ACCELERATING PACE OF CHANGE:
computing power, information in scientific journals, global population, environmental change and many other aspects of modern life are undergoing rapid if not exponential increases. This rate of scientific and technological change is increasing human opportunity but also social and environmental risk. We have become used to this acceleration of history, as surprising technological advances become commonplace news items. However, many of these changes are driven by corporate motivations and are often already developed before their full ethical consequences can be properly debated. Each technological advance is progressive from the previous technologies, so there is a certain "spike" in the future beyond which prediction may be impossible.

ACCIDENT : Accidents are usually thought of as any events which were not in tended. Some accidents, like auto accidents, are bad. Others, like accidentally finding a treasure trove of gold, are good accidents. Another kind of accident would be an event which unpredictable. By "unpredictable" is not meant "hard to predict", or " i mpossible to forsee given current knowledge or methods". What is meant is an event which even God, or someone with perfect knowledge of all preconditions and scientific laws, would not have been able to predict. Some people think that events of the kin d which are studied in mathematical theories of chaos are accidental in this sense. But they are not, because chaotic systems are perfectly deterministic and predictable by means of mathematical functions. These functions are "non-linear", however. Whet h er or not an event is "accidental" is probably only a function of our ignorance. If we know the causes of an event, we say that it was determined. If we are ignorant of the causes, we call it "accidental".(FL)

ACCURACY: 1. correctness; 2. the extent to which a measurement is close to the actual value of a quantity being measured. Accuracy is the correctness of a measurement compared to the actually existing value or standard. In mathematics the accuracy of a number is expressed by its number of decimal places or of significant digits (e.g. 3.14 is accurate to 3 significant digits). (See PRECISION) (MP+RW)
ACETYLCHOLINE (ACh) : a major and widely distributed peripheral and brain neurotransmitter. ACh, first synthesized in 1867, is a cholinergic neurotransmitter with the primary function mediating synaptic activity of the nervous system and skeletal muscles. ACh is rapidly degraded by acetylcholinesterase (AChE) which prevents accumulation of the neurotransmitter. Naturally occurring ACh agonists include pilocarpine, muscarine (mushrooms) and arecoline (betel nuts). Symptoms of intoxication include salivation, nausea, vomiting, headache, visual disturbances, diarrhea, decreased heart rate and blood pressure, shock and possibly death. The best known antagonist is atropine but there is also scopolamine and related belladonna alkaloids, which are found in plants such as deadly nightshade. The ACh antagonists cause dryness of the mouth, increased heart rate, dilated pupils, difficulty swallowing, atazia, restlessness, hallucinations and coma. A number of insecticides and nerve gases block AChE which results in elevated levels of ACh that can be fatal; hence the use of atropine to contract these effects.

ACTIVISM: Self-initiated action and activity towards an ideological, political or environmental cause. Democratic countries encourage freedom of expression, and protest may include petitions, public marches, civil disobedience and media attention. Direct action is action outside the normal procedural system. There is opportunity for official activism from within charities, non-profit and non-government organizations. Workers activism may include mass refusals to work - the strike or industrial action. Creatively attracting the media to an issue is one method used by social and environmenten change destructive practices once exposed to the camera spotlight. Appropriating the power of media to a cause has been called culture jamming. The internet has created a forum for uncontrolled discussion and organization of activism, as well as the online vandalism of hacktivism. Sometimet activism undermines the cause and is sometimes branded ecoterrorism. Quite the RESISTANCE,NATIVE PARADIGM) (MP)

ACUPUNCTURE: A Chinese traditional system of healing. This system treats various ailments by means of inserting small needles into the skin briefly at specific locations. These locations are known as "acupuncture points", and groups of these points are classed together in "meridians", of which there are twelve major ones. The system of acupuncture is popular in East Asia, and in recent decades has gained prominence in the West as well, as a method of controlling pain. The theory behind acupuncture is quite complex, involving the interaction of different organs with the Five Elements (see FIVE ELEMENTS) and with Yin and Yang (see YIN AND YANG). The central texts on acupuncture are written in classical Chinese, although some texts have been translated. (AG)

ADAPT: (Latin: adaptâre to fit to) The adjustment of behaviour, form or function as a result of changes in the surrounding environment or circumstances. For something to adapt, it must change or modify to suit a different purpose. Biology adapts during evolution, technology adapts to modernity, but most importantly for ethics, belief systems and human behaviours must adapt to suit an increasingly crowded and limited Earth. (See ADAPTATION, ADAPTIVE THINKING, ADAPTIVE MANAGEMENT, HUMAN EXTINCTION). (MP)
ADAPTABILITY : The ability to adjust with changes in circumstances is an important attribute for effective learning, personality development, planning, management, marketing, development and technological implementation. (See ADAPTIVE THINKING) (MP)
ADAPTATION : 1. in evolutionary biology a particular structure, physiological process or behavior that provides an organism with an advantage to better survive and reproduce; 2. the evolutionary process which leads to the development or modification of an existing structure or function in response to a changed environment; 3. the physiological response of sensory receptor organs (vision, touch, temperature, olfaction, audition and pain) to stimuli from the continually changing environment; 4. the conscious or unconscious modification of an individual adjusting to changing social and cultural surroundings. (IP)
ADAPTIVE MANAGEMENT: Adaptive management is handling, direction and control, which is responsive to changing circumstances. Ecological, sociopolitical and corporate management strategies are most effective when easily adapted and modified to accommodate changed environments, superior information or new motivations. This is a continuous dynamic process involving environmental and economic monitoring and assessment. Elements associated with adaptive management include: the collection and incorporation of new information, evidence-based management, adaptive modification of plans and strategies, the precautionary principle, strategic environmental assessment, environmental impact assessment, mitigation and contingency planning, taking opportunities rather than waiting for them, learning from the mistakes of others as well as your own, openness to innovation and responsiveness to critical input into the process.

ADD: See ATTENTION DEFICIT HYPERACTIVITY DISORDER
ADDICTION: (Latin: addicere to devote) Compulsive, uncontrollable dependence on a substance, habit or practice to such a degree that cessation causes severe emotional and/or physical responses; however, the term is most often used in the context of drug addiction. Because drug addiction is a difficult concept to define, a WHO expert committee in 1970 substituted the words "drug dependence" which is characterized by psychological symptoms such as craving and a compulsion to take the drug on a continuous or periodic basis, with serious emotional and physical side-effects developing when the drug is withheld. The drugs of major concern (all causing physical and/or psychological symptoms of dependence) are alcohol, nicotine, the opiates, the sedatives particularly barbiturates, stimulants such as cocaine and the amphetamines, the hallucinogens like mescaline and lysergic acid diethylamide (LSD), and cannabis also known as marijuana, pot, dope or hashish. Although government concern centers primarily on illegal drug abuse such as heroin, the adverse effects of these is relatively small in comparison with the very large number of people dependent on alcohol and tobacco. Furthermore, few addicts confine their intake to a single substance, and synergistic interactions are often many times more hazardous than the additive effects would indicate. Dopamine is the messenger of the brains reward systems and has been dubbed the courier of addiction because many paths of pleasure in the brain employ dopamine messengers in their reinforcement. Mine in the brain and stimulate this reward system. For example, the "buzz" described by those taking amphetamines (better known as speed), or the "rush" of snf the sudden increase of brain dopamine activity that these drugs stimulate. Consequently, it is not entirely by accident that the ingenious human species hasts - often with pain and illness to themselves and their offspring as a result - of the natural intoxicants like alcohol, tobacco, opium and cocaine. Thereforponsibility and intelligent realism when it comes to caring for oneself, and if that fails judicious pharmacological intervention plus a program of self-educaand prevention (Latin addicere to devote) (see FETAL ALCOHOL SYNDROME; DRUG TOLERANCE; INDIVIDUAL DRUG ENTRIES; INTERNET ADDICTION; GAMBLING ADDICTION).

ADOLESCENCE: the period between childhood and adulthood when, typically, dependence and immaturity are replaced by independence and maturity. In the USA it is the age designation for humans 13-18 years old. Adolescence is a time of emotional fluctuation and vulnerability due to the biological effects of rising sex hormone secretion and heightened libido. It may be a time of identity crisis, changing body image, experimentation with sex roles and sexuality (see PUBERTY). (IP, DM)
ADOPTION : The bringing of someone into a relationship that (s)he did not previously enjoy. Normally used to refer to the taking into a family of a baby or young person. Such adoptees generally have the legal privileges of natural daughters and sons. Refers to the integration of a child, born to another couple, into a family who decides to take care, educate and give love to this child. Law rules strictly the qualifications needed for adoption; usually, it is requested that the couple be composed by father and mother, but in some occasions, a single mother or father is also allowed to adopt. Third world countries bestow an elevated number of children for adoption to couples from wealthy countries. Usually, children for adoption have been previously abandoned or given to special institutions for this purpose. In most cases, these children are born to single women, whose economical situation does not allow them to raise a child, or are the outcome of rape. Unmarried pregnant young women in particular families are also sometimes forced by these to give their baby away for adoption. Since abortion is prohibited in most of these countries, they all have in the majority of cases no other way to solve the problem. Many hundreds of children around the world are adopted per year, but still many more remain in institutions awaiting for someone to give them a better life. In some countries, like Japan, adoption of older persons occurs. (MR+GK)
ADRENAL GLANDS : Paired organs situated on top of each kidney. Each adrenal gland is in fact two separate glands: a) the adrenal cortex (the outer portion) which synthesizes three principal classes of hormones - the glucocorticoids such as cortisol (implicated in stress physiology), the mineralocorticoids such as aldosterone (implicated in ionic balance of body fluids) and smaller amounts of sex hormones such as androgens and estrogens and b) the adrenal medulla (the inner portion) which consists of sympathetic neurons that secrete adrenaline and noradrenaline facilitating the alarm reaction of the General Adaptation Syndrome. (See ADRENALINE; GENERAL ADAPTATION SYNDROME; HOMEOSTASIS). (IP)
ADRENALINE : (Latin ad 'at' + ren 'kidney') Also known as epinephrine, is the 'fight-or-flight' hormone secreted by the adrenal medulla and affecting circulation, muscular action and general arousal. It also acts as a catecholamine neurotransmitter and provides the reaction sought after by the so called "adrenaline junkies". (See ADRENALINE JUNKIES; GENERAL ADAPTATION SYNDROME; ADRENAL GLANDS). (IP+MP)
ADRENALINE JUNKIE: A person who habitually engages in risk-taking behavior such as extreme sports, due to a more than usual enjoyment in the associated releases of adrenaline or related hormones and neurotransmitters. (See ADRENALINE, JUNKIE) (MP)
ADULTS : Important for definition in relation to consent. Varies between countries. In the USA it is the age designation for humans 19-64 years old, with those 65 years and older being referred to as the aged. For bioethics purposes those persons 18 years and older are given legal competence in most countries. (See CONSENT). (DM).
ADULTERY: voluntary sexual intercourse between a married person and any other than the lawful spouse. In many countries adultery has been the principal ground for divorce and in earlier periods was even punishable by death, but despite legal and cultural prohibitions adultery has persisted throughout history. Various published surveys originating in the west have indicate that at least 50% of married men and women admit to having sexual intercourse after marriage with a person other than their spouse. From the biological perspective, the practice may represent a subconscious desire to outbreed and gain fitness by increased genetic diversity. (See SPERM COMPETITION, MARRIAGE, OPEN MARRIAGE, SWINGING, MISTRESS, CONCUBINE, COURTESAN, CUCKOLD, DIVORCE). (IP)
ADVANCE DIRECTIVES : Declarations by patients, made in advance of a situation in which they may be incompetent or unable to decide about their own care, stating their treatment preferences or authorizing a third party to make decisions for them. These include various documents including Durable power of attorney, Living wills, Psychiatric wills, Donor cards. (See also LIVING WILL, RIGHT TO DIE, EUTHANASIA). (DM+IP)

AEROBIC: Pertaining to the presence of air or oxygen, or requiring oxygen for the maintenance of life (Greek aer air) (see AEROBIC EXERCISE, ANAEROBIC). (IP)
AEROBIC EXERCISE : any physical exercise which requires additional effort by the heart and lungs to meet the increased respiratory demand for oxygen. The activity is beneficial for all body components and it is significant to note that physical activity need not consist of an organized exercise program because simple pleasures, such as bush walking, gardening and other homely physical activities, also burn off excess calories which, if unused, turn to fat. Regular gentle aerobic exercise is important in pregnancy, however, since pregnancy requires a high degree of reflex coordination high impact sports needing a good sense of balance; such as water and snow skiing, diving, ice skating and riding, should be avoided. (See ANAEROBIC EXERCISE). (IP)
AEROBICS : See AEROBIC EXERCISE.
AEROSOLS: are small particulates both natural and synthetic which are potentially of great importance climatically. The general trend suggests that they are increasing over the globe, particularly over industrial regions of the Northern Hemisphere where they reduce solar radiation reaching the surface of the Earth. The colloquial epithet "aerosol abuse" has been used to highlight harm caused from industrial aerosols by the environmentally irresponsible (see NUCLEAR WINTER). (IP)
AESTHETICS : The appreciation of beauty and appearance. (DM)

AFFIRMATIVE ACTION: The positive treatment of minority groups. Some say that positive discrimination is still discrimination, but affirmative action helps rebuild bridges of opportunity, and is a form of acknowledgement for past wrongs and the legacies of slavery, Colonialism and the dispossession of indigenous people. Examples of affirmative action include the Affirmative Action (Equal Employment Opportunity for Women) Act (Australia), Indigenous land management, educational privileges, healthcare assistance and social welfare assistance.

AFRO-AMERICAN : This term is used to designate the African descendants born in the United States of America. It has replaced the terms of "colored" or "black", which had a racist connotation. The word also vindicates the cultural relationship of these American descendants with the African cultures. Afro-American is also used in a broad sense to designate the Afro-descendants of all America, North, Central and South. (GK)
AFRO-COLOMBIAN, AFRO-BRAZILIAN : In those countries of South America, where a considerable part of the population descend from African immigrants, these people recognize themselves as Afro-Colombians of Afro-Brazilians. Many cultural traits have survived admixture and imposition of the dominant European culture. This is particularly true in music, dance, funerary rituals, marriage, extended families, etc. In Colombia, some of these groups have even maintained a Bantu related language, a pidgin language called "palenquero". (GK)
AGAPE: In the Greek language, three verbs can be used for the English word love, namely eros, phileo and agapao. These there verbs mean sensual love, brotherly love and self-giving love respectively. Agape love indicates the supreme and a nobler form of love, as seen in the sacrificial death of the Lord Jesus Christ on the cross for all human sin. Both Jews and Gentiles have a practice of fellowship and brotherhood means. The name agape can also indicate such fellowship meal. (JA)
AGE : Age factors are used when age is discussed as in relation to a subject or problem example, age of consent, or age related quality of life.

In developed countries with fewer children there is occurring a graying of the population, whereas many less developed countries have the reverse, a youth bulge. Age distrT, LIFE CYCLE) (MP)
AGE OF CONSENT: The age at which consenting sexual intercourse becomes legal, commonly at 16 years. More broadly, also the ages at which other rights of adults are conferred onto kids, such as driving, drinking alcohol and voting. (See ADULTS, CONSENT) (MP)
AGE/SEX PYRAMID: The Age/Sex Pyramid is a frequency distribution histogram displaying population composition according to age group (vertical scale) and gender (left/right), useful for illustrating age-specific birth, death, disease, fertility rates etc. (See AGE DISTRIBUTION) (MP)
: In the USA this is the age designation for humans 65 years or older. Many persons in modern society live into advanced age, so the definition of 65 years or older may not be ethically relevant. Homes for the aged, pension schemes, senile dementia, and ageism (age-related discrimination in access to health care or other social services) are important issues. (See QUALITY OF LIFE). (DM)
AGENDA 21: An environmental, social and economic action plan for the 21 st Century based upon principles of sustainable development. Agenda 21 was arranged and approved by many countries during the Rio de Janeiro United Nations Conference on Environment and Development (UNCED 1992). Although it suffers from negotiated compromise and is not legally binding, it is nevertheless an ambitious first international attempt to reconcile development and environment issues. (See EARTH SUMMIT, CONVENTION OF BIOLOGICAL DIVERSITY, SUSTAINABLE DEVELOPMENT). (MP)
AGENT ORANGE : the U.S. military code name of a mixture of herbicides used as a defoliant agent in Southeast Asia to deny communist soldiers jungle cover during the 1960s war in Vietnam. It is claimed that exposure to this agent is a cause of generations of birth defects and other inherited ailments including cancer, neuropathy and a variety of chronic diseases, however, confirmation of any such linkage would take decades of further research; thus, compensation demands from Hanoi and U.S. veterans are easily dismissed. Spraying was halted in 1971 when it was discovered that Agent Orange was contaminated with the highly toxic chemical dioxin, which is capable of harming human and animal health and has well-established multigenerational adverse health effects. Despite uncertainty as to the long-term effects of the wartime defoliant, there is the view that Washington and Agent Orange manufacturers, Dow Chemical Co. and Monsanto Co., have a moral duty to compensate Vietnamese who have suffered from exposure. (See VIETNAM WAR, DIOXIN). (IP)
AGGRESSION: Hostile or malicious actions or behavior; the act of violating by force the rights of another individual or group, including territorial rights. Aggressive behavior may have a genetic component, however it is likely to be predominantly a learned response in humans, precipitated by environmental variables such as periods of stress. Males have a higher incidence of fighting, crime, verbal aggression and fantasy aggression, although females will aggressively protect their young. Human aggression can be reduced by a nurturing environment of social responsibility from a young age. (see AGGRESSOR NATION, DESENSITIZATION, VIOLENT MEDIA, WARFARE). (MP)
AGGRESSOR NATION: The nation state which attacks, initiates or first declares a situation of warfare with another nation. Although it may sometimes be difficult, due to historical and social circumstances or wartime propaganda, the decisive determination of who was the aggressor nation can be a useful step in ethical conflict resolution, mediation and peace enforcement. (See INSTITUTION OF WAR, PEACE ENFORCEMENT) (MP)
AGRICULTURE Cultivation of crops and domestication of farm animals. Seems to have happened independently around 10 000 to 8000 BCE in the Middle East, the Orient and the Americas. Involves four processes: (1) Breeding of animals or sowing of seeds; (2) Caring for the animals or plants; (3) Collecting produce (e.g. harvesting, milking, slaughtering); (4) Selecting and keeping back some of the produce for the next generation. (MR)
AGING : A natural biological process beginning soon after birth, and ending with death. In most ancient cultures, youngsters honored aged persons, seen as experienced, wise people. Still sometimes in aboriginal groups, one of the old men or women is chosen as the shaman, and given the religious, medical and political leadership of the whole community. Today, aging is seen in western countries as a fatal issue of life, and many hope that, with ongoing progress of biomedical sciences, its happening will be thrown back many years. Also, due to better life conditions and health care programs, people get older than decades before. In both cases, a high input of money and human endeavor is needed to give aging people an adequate life quality. Ethical considerations must balance the justification of these efforts face to other more poignant problems of humanity, as is famine, misery, war mutilations, basic health care, etc. (GK)
AGNOSTIC: (Greek: agnostos 'unknown') Holding the belief that because nothing is known about the existence of God there is the need to keeps an open mind beyond physical/ biological phenomena. The Victorian biologist and philosopher T.H. Huxley coined the term stating that in his opinion the laws of Nature could quite satisfactorily explain all natural phenomena and could not find a logical need for the existence of God. [Greek agnostos unknown] (IP)
AGRICULTURAL ETHICS : The study of the ethical issues associated by agriculture, aquaculture and fishing. May also include forestry in common discussions, e.g. the Ethics in Food and Agriculture program on FAO (www.fao.org). There are numerous topics discussed in the use of agriculture, and some are reflected in documents relating to agriculture, including the debates over the use of animals, the concept of quality of life for animals, the concept of Maximum Sustainable Yield in fishing, the Land Charter, Peasant's Charter, the Pesticide Convention, and access to, and conservation of, genetic resources, for example. (DM)
AGRICULTURE : The planned cultivation and/or nurture of living organisms to provide food or other products, e.g. wool, cotton. Often also called farming. Origins are unsure, but commonly considered to be seen in the past ten thousand years of human culture. There are possible signs of agriculture in humans over the past hundred thousand years. Some agriculture is seen in other species as well, at much earlier points in history. (DM)
AGROBACTERIUM: (Agro = soil) Agrobacterium tumefaciens a common soil bacteria that can naturally carry genetic information (DNA) into plant cells by infecting wound sites on plant stems (JA)
AGRO-BIOTECHNOLOGY: The application of biotechnology to agriculture, such as the use of modern recombinant DNA technology in plant breeding programs to increase crop yield or disease resistance. In addition to creating genetically modified novel crop varieties, agro-biotechnology is also used by conservationists to maintain a viable global supply of germ plasm in order to safeguard future genetic diversity and a continuing crop inventory. (see AGROTECHNOLOGY, GENETIC ENGINEERING) (MP & IP)
AGROFORESTRY: (Agronomy + Forestry) A farming practice which integrates timber plantation with agricultural production on the same area of land. The combination of trees with crops not only provides a diversification of produce, but also provides habitat and protection from soil erosion and salinity. (See PERMACULTURE, TREE PLANTING). (MP)
AGRONOMICS: The economics of agronomy, for example the productivity of cultivation practices or the trade and distribution of agricultural products. (MP)
AGRONOMY: The science of agricultural cultivation, land and soil management, and the production of crops. (See AGRICULTURE) (MP)
AGROTECHNOLOGY: (Agronomy + technology) The application of science-based technology to agricultural production; the technological means by which humans exploit farm ecosystems, artificially eliminating natural species competition and manipulating the system to increase its yield of products of high value to humans. Examples include modern agricultural equipment such as hydroponics, agri-business such as large government-financed breeding programs, and agro-biotechnology such as genetically modified crops.

AIDS: acronym for Acquired Immunodeficiency Syndrome - the clinical end stage of human immunodeficiency virus (HIV) infection which results in severe, irreversible immune suppression. After sufficient immune system damage has occurred, the individual becomes susceptible to infection by many opportunistic diseases including cancers. These opportunistic diseases then become the indirect markers of AIDS; thus, AIDS is a syndrome or collection of many diseases resulting from HIV infection. The conditions was first noticed by doctors in the 1970s and formally described under the name acquired immune deficiency state in 1980. At first AIDS was identified as principally affecting two groups: drug users who shared needles and male homosexuals but now its principally spread by the heterosexual community and bisexual males, and can be passed through the placenta and breast milk to the children of thosets and kills CD4+ lymphocytes (T helper cells) weakening the immune systems ability to fight infection. HIV may also invade macrophages and brain cecourse, semen and contaminated blood. All semen donors are initially testeill within the incubation period), before the donor product may be used in any IVF clinic.
A patient may be diagnosed as having AIDS if infected with HIV virus and a CD4+ count below 200-500 cells per milliliter of blood. Low cell count is usually accompanied by symptoms of extreme fatigue, intermittent fever, night sweats, chills, lymphadenopathy, enlarged spleen, severe diarrhea and weight loss, apathy and depression. Treatment consists primarily of combined chemotherapy, such as the antiviral drug AZT, to counteract the opportunistic infections but no cure has yet been found. Public awareness and sex education, particularly of adolescents, must remain a high priority. (See SYPHILIS). (DM+IP)
AIDS SERODIAGNOSIS : Immunologic tests for the identification of HIV (HTLV-III/LAV) antibodies; includes assays for HIVseropositivity and seronegativity which have been developed for detecting persons carrying the viral antibody. (DM+)

AIR POLLUTION : Gases, liquids and solids which, when added to the normal composition of the atmosphere, may be hazardous to biology, ecology or human health. Processes leading to pollution of the atmosphere include attrition, vaporization and combustion. Types and sources of air pollution include photochemical smog, transportation exhausts, incinerator emissions, forest fire smoke, industrial discharges, greenhouse gases (carbon dioxide, nitrous oxides, CFCs etc.), suspended particulates, oxides of carbon and sulfur, inorganic and organic acids, toxic chemicals, trace elements, irritants and odors. Grit is sharp particulate matter such as dust which may cause skin and eye irritation. Grime is accumulated soot or dirt which adheres to a person or cityscape. Airborne particles may adsorb corrosive chemicals leading to the erosion of infrastructure and monuments. Air pollution epidemics are a recurring health problem in many major urban centers. Monitoring and regulation are beginning to improve in the developed world, with air pollution meteorology and models becoming more common in weather forecasts. Emissions may be controlled or reduced by absorption, adsorption, mechanical collection, air pollutant incineration, catalytic conversion, electrostatic precipitation, fabric filters, wet collectors, mechanical cyclones, smokestack scrubbers and other pollution control devices - often legally regulated but also self-initiated by visionary companies. (See POLLUTION, WATER POLLUTION, ATMOSPHERE, GREENHOUSE GASES, ACID RAIN) (MP)
AKIDO vs UESHIBA, MORIHEI: A Japanese martial art, based on ancient tradition derived from the Samurai. But while Japanese martial arts formerly combined both violent and peaceful aspects, Aikido is one of those arts which, after World War II, has been emphasizing the peaceful, seeing martial techniques as ways of discouraging a violent attacker without hurting him or her seriously, eventually leading to love and peace. It is for these reasons that martial arts can be important to bioethics. (FL)
ALCOHOL: (Arabic: alkohl 'subtle essence') A clear water miscible organic substance obtained by fermentation with one or more hydroxyl (OH - ) groups; but in common parlance refers to the ethyl alcohol or spirit contained in any beverage such as wine or liquor.

ALDRIN : A dangerous chlorinated hydrocarbon pesticide, one of the 'dirty dozen' persistent organic pollutants. (See PERSISTENT ORGANIC POLLUTANTS) (MP)
ALEXITHYMIA: lack of emotionality or an inability to consciously experience and communicate feelings (see AXIODRAMA, EMOTIONAL INTELLIGENCE). (IP)
ALGAE: (Latin: alga "seaweed") A wide diversity of chiefly aquatic organisms comprising the seaweeds and various freshwater forms varying in appearance and size from single celled phytoplankton to multicellular macroalgae such as kelps. They are the Earths dominant autotrophs supplying 50-60% of all photosynthesis on Earth (see AUTOTROPH, LICHENS). (MP & IP)
ALGAL BLOOM: A suffocating build-up of rapidly multiplying algae and bacteria, occurring in phosphorus enriched waterways caused by run-off sewage, fertilizers and the processes of eutrophication. The resulting increased biological activity transforms the water-mass green or red with large-scale decomposition rendering the habitat malodorous and toxic. Since all available oxygen is utilized by the bloom, anaerobic organisms begin to dominate the sediments, killing most of the animals from the previously viable aquatic habitat (see EUTROPHICATION & FISH KILLS). (MP & IP)
ALGEBRA : the branch of mathematics in which symbols (e.g. x,y,z ) are used to represent numbers or variables in arithmetic operations. (See ARITHMETIC). (IP)
AL-GHAZALI: (1058-1111)- Muslim scholar, theologian and Sufi, author of "Ihya Ulum al-Din" ("Revivification of the Religious Sciences"). In his major work , "Ihya Ulum al-Din", Al-Ghazali explains and clarifies in four parts, the foundation of the beliefs of Islam, and the path of the Sufi. The first part deals with basic principles, the concept of worship in Islam and the importance of study and seeking knowledge. The second part deals with many matters of ethics. The third section deals with the evil traits that should be avoided, as they are an obstacle to approaching God. The fourth section deals with the stages of spiritual purification that are needed in order to attain salvation. (AG)
ALGORITHM: A set of steps or instructions which precisely describe a limited procedure or task. Computer programs are written in programming languages designed around the requirements for precision and coordination of sets of algorithms. (See COMPUTER, ARTIFICIAL LANGUAGES, GENETIC ALGORITHM) (MP)
It is certainly possible, perhaps probable, that life is common across the universe. Readings from distant sources in the galaxy have detected some chemical constituents of chlorophyll and amino acids. One serious scientific theory proposes that ice from impacting comets may have delivered the first building blocks of life to Earth. Solar systems with planets similar to our own are relatively common, estimated conservatively by Harvard Universitys Harlow Shapley at more than one hundred million fcts for life in our solar system are on Europa, oneeport flying saucers and alien abductions. Scientifent life cannot be found because it quickly tends to destroy itself with its own technology. (See LIFE, SETI, ORIGIN OF LIFE) (MP)
ALIENS : Beings from another planet. Ethical issues relating to the human attitude to aliens has been extensively discussed in science fiction literature. The term is also used in Japan and the USA to refer to foreigners. (DM)
ALLAH : Allah is special name for God in Arabic. In Islamic belief, Allah alone is the true God for all that exists who has no partners or rivals. The Quran mentions 100 names for God, which in deed they are adjectives and each one expresses one of His attributes. Allah is not a descriptive name like other ninety nine names and attributes such as The Merciful, The Beneficent. The name Allah, itself contains all these attributes. There is no consensus that the word Allah is compounded of "al" the definite article and "ilah", meaning "a god". The Qur`an mentions the word "Allah" have also been used in pre-Islamic times.This word is used by all Arabic speaking, Muslims, Christians Jews and others. (See QURAN) (AB).
ALLELES: Alternative forms of a genetic locus; alleles are inherited separately from each parent (e.g. at a locus for eye color there might be alleles resulting in blue or brown eyes). (DM) Alleles arise through mutations in a given DNA sequence. If the locus codes for a protein, alleles can result in different phenotypes. Alleles can be dominant (a single dose is sufficient for expression of the phenotype) or recessive (both genes must carry a mutant allele in order to express the trait). At the genotype level, the alleles at a given locus are co-dominant. Different alleles can also be found in silent regions of the genome (the non-coding part of the genome) (see STR, VNTR, SNP, RFLP). Some loci are bi-allelic, having only two alternative forms, but the most useful loci for gene mapping, population studies and human identification analyses are those which are multiallelic, resulting in a high polymorphism content of the locus at the population level.

ALLOGRAFT : (Greek allos "other" + graphion "stylus") also called homograft, a non-permanent graft of tissue between two genetically different individuals of the same species such as a tissues transplant between two individuals who are not identical twins. The graft material can include, for example, cadaver skin stored in a tissue-bank. (See AUTOGRAFT, XENOGRAFT). (IP)
ALLOPATRIC SPECIATION : Evolutionary divergence of populations which forms different species due to geographic separation, which do not interbreed. (JA)
ALLOPATRY: (Greek: allo "other" and Latin: patria "homeland"). Occupying different geographic distributions or ranges. (See ALLOPATRIC SPECIATION, SYMPATRY) (MP)
ALLOSTASIS: (Greek: allo 'variable' + stasis 'stability') literally 'achieving stability through change' describes the mechanisms which enable the body to withstand challenge. Allostatic systems, particularly the nervous, hormonal and immune complexes, protect the body by adapting to the ever-changing internal and external demands made on it. Allostatic load refers to the price of adaptation; that is, the accumulated wear and tear from chronic over- or underactivity of the allostatic systems (see STRESS, HOPE and WELLBEING). (IP)
ALLOWABLE CATCH : See TOTAL ALLOWABLE CATCH.
ALLOWING TO DIE: Thee withdrawal or withholding of life-prolonging treatment. This is often referred to as Passive euthanasia, and is sometimes effected through Do not Resuscitate (DNR) orders.

AL-RAZI (RHAZES) ; 865-925, Muslim scholar, physician and chemist. He was born at Ray, Iran. Author of works on medicine, pharmacology and philosophy. His contribution to medicine was so significant that it can be compared to that of Ibn Sina, his share, greatly influenced the development of science in general and medicine in particular. In his method, he took patient's history and clinical observation in medical practice.
He wrote around 50 books only in medicine and some of his famous books on medicine are: Al-Hawi, which contained various medical subjects and all important information that was available from Greek and Arab sources including his own remarks based on his experiences and views; "Al-Judrai Wal Hassba" was the first book to draw clear comparisons between smallpox and chicken-pox. He also prepared alcohol by fermenting sweet products. (AB)
ALTERED STATES OF CONSCIOUSNESS: An abnormal state of mind. Space and time may appear to be suspended, and the psyche (mind/soul) may seem detached from the body (soma). Such a condition may be the result of meditation, mystical prayer, ritualistic ceremonies, orgiastic dancing, sleep deprivation, starvation, shock, hypnosis, mental illness, mind-altering drugs and of course dreaming. (See MEDITATION, DREAM, RECREATIONAL DRUGS, HYPNOSIS, MANIA, DEPERSONALIZATION, DISSOCIATION) (IP & MP)
ALTERNATIVE ENERGY: See RENEWABLE ENERGY.
ALTERNATIVE PARADIGM: An up-and-coming alternative social framework or world-view. The new environmental paradigm places intrinsic value in the preservation of nature, is eco-centric, based on soft power and soft technology, treats economics only as a means to an end, recognizes limits to growth, condones collaborative, leisurely and sufficiency lifestyles, believes in grassroots organization, decentralization, people power and nonviolent direct action, is non-consumeristic and non-nuclear, promotes sustainable development and ethical value systems, and encourages compassion and tolerance towards other species, human groups, and future generations. (See DOMINANT PARADIGM, PARADIGM SHIFT, GREEN MOVEMENT, PEACE MOVEMENT, ANTI-GLOBALIZATION MOVEMENT, SOFT POWER, SOFT TECHNOLOGY, HIPPIES, NONVIOLENT DIRECT ACTION, ACTIVISM, DEVELOPMENT, SUSTAINABLE DEVELOPMENT, PROGRESS, UTOPIA) (MP)
: Unorthodox or unconventional or complementary therapeutic systems and therapies. What is unconventional in some parts of the world may be very conventional in others. For example Ayurvedic and Chinese medicine are unconventional in the West, but quite conventional in the East. Although Western physicians have had a very negative attitude in the past, to what is regarded as unconventional, there are now increasingly many attempts at scientific clinical trials of alternative medicine. The idea of "integrative medicine", seeking to integrate the best from various methods, may replace old ideas of what is conventional and what isn't.
Concepts in some alternative therapies, like the energy which is called ki in Japanese, and chi in Chinese, are a challenge to philosophies of science which, since Newton and Hume, have been trying to rid science of mysterious concepts of energy . (DM)(FL)
The dilutions in Homeopathy, moreover, are a challenge to orthodox chemistry. Sometimes, when new developments seem to contradict science, we reject the new developments. Sometimes, we revise orthodox science. The astronomical observations made after the invention of the telescope were difficult, if not impossible, to reconcile with Ptolemaic astronomy. Rather than rejecting the new observations, Copernicus, Kepler and Galileo rejected Ptolemaic astronomy. It will be interesting to see whether the future will bring a reaffirmation of orthodox science, and a rejection of unorthodox medicine, or the exact opposite. Or perhaps there will be a new synthesis that we have not yet thought of. (DM, FL)
ALTERNATIVES: (MP) (See DECISION MAKING, DECISION SUPPORT SYSTEMS)
ALTRUISM : Social interaction, a behavior of doing good to another at the expense of its own welfare. Disinterested altruism is a disadvantage from an evolutionary viewpoint. A gene can be altruistic if promotes the welfare of another entity. Opp. Selfish = opposite sense. There are however interested forms of altruism, which may favour survival of the individual or the species, by being cooperative. (JA, DM)
ALZHEIMERs DISEASE : Also called senile dementia-Alzheimer type after Alois Alzheimer, neurologist, 1864-1915. It is characterized by progressive and irreversible mental deterioration, confusion, memory failure, disorientation, restlessness, speech and movement disturbances and hallucinosis (See DEMENTIA; PSYCHOSIS). (IP+DR)
AMBIGUITY: Vague or uncertain meaning; the possibility of multiple distinct interpretations of a single expression. Ambiguity and circumlocution are tools used by politicians to avoid sensitive lines of questioning. Ambiguity can be beneficial to the spread of some memes, for example the term "sustainable development" has broad appeal to both environmentalists and developers precisely because of its ambiguity. The ambiguities of language may provide the subtleties of literature, but language precision is centrally important to bioethical policy and scientific discourse where ambiguity can obscure important assumptions or methodological details. (See DEFINITION, EUPHEMISM) (MP)
AMERINDIAN : Definition adopted by anthropologists to call the inhabitants of the Americas belonging to one of the three main linguistic families defined by Joseph Greenberg, the Amerind speaking peoples. In modern biological anthropology and genetics, this term has been adopted to designate a group of present-day native American peoples from North-, Central- and South America in all the studies of the biological variation that attempt to characterize the DNA polymorphisms of different loci in these and other human groups. Although the linguistic classification of the Native American languages remains controversial, the term is now coined for the peoples inhabiting this part of the planet. (GK)
AMINO ACID: Any of a group of 20 molecules that combine to form proteins in living things. Chemically they contain an amino group, -NH2, and a carboxyl group, -COOH. The sequence of amino acids in a protein is determined by the genetic code. There are actually 21 in number, with the 21 st , selenocysteine, being seldom used. They are the building blocks to form proteins, e.g. Glycine. (DM+JA)
AMNESIA: (Greek: mnasthai "to forget") Memory loss caused by brain damage or severe emotional trauma. Usually only certain sections of the memory are affected, for example anterograde amnesia is the inability to form new memories since the onset of amnesia, whilst still allowing the retention of language and other basic skills. (See MEMORY IMPAIRMENT) (MP)
AMNIOCENTESIS : Diagnostic sampling of the amniotic fluid during pregnancy, usually performed by insertion of a needle into the amniotic cavity which surrounds the foetus during pregnancy. Performed for prenatal screening. (see PRENATAL DIAGNOSIS) (IP, DM). Amniocentesis is followed by either a karyotype (see KARYOTYPE ANALYSIS) to explore the possibility of a chromosomal abnormality in the foetus, or by a molecular genetic test for a particular genetic disease. Usually, amniocentesis is accompanied by genetic counselling; in the case the test results indicate a genetic abnormality in the foetus, parents are given the choice of either interrupting or pursuing the pregnancy. Amniocentesis for Down Syndrome detection is mandatory in many countries for women over 35 years, due to the increased risk from this age on, but in many countries, amniocentesis, and thus, prenatal diagnosis, is not even permitted, on grounds of the illegality of abortion. Nevertheless, bioethicists and lawyers have pointed that the right to know has to be respected above any other consideration. In the case of a positive result for Down syndrome or any other genetic condition, it may help parents and other family members in preparing themselves psychologically to accept the baby, whereas, in the case of a negative result, throwing out the presence of such a problem, the parents are relieved of an unnecessary anxiety during pregnancy (GK).
: The fluid in which the fetus floats. (JA)
AMOTIVATIONAL SYNDROME : The loss of interest, drive and progress in certain normal aspects of life. These may include social life, for example non-maintenance of friendships, lost interest in outdoor recreation or reduced sex drive; or more commonly in working life, for example a decline in productivity or performance, dropping out of student courses or regular non-attendance at work. Amotivational Syndrome may be an indication of depression, anxiety, persistent drug use or other conditions with symptoms of dullness and lethargy. (See MOTIVATION). (IP+MP)
AMPHETAMINES : Central nervous system stimulants, commonly amphetamine sulfate which has the trade name Benzedrine. Developed in the 1920s, amphetamines and their relatives have been used to treat depression, obesity, narcolepsy and attention deficit hyperactivity disorder. Amphetamines are subject to abuse because of their stimulant properties, which include wakefulness, excitement and increased energy levels, but they are also attractive because of their ability to generate an addictive euphoria when they are ingested, injected or snorted. Abuse can lead to compulsive behavior, dependence, hostility, paranoia, hallucinations, physical deterioration - particularly cardio-vascular - and suicidal tendencies. Regular use may also lead to serious amphetamine-induced psychosis. Amphetamines have many street names such as "speed", "black beauties", "lid poppers", "pep pills" but also "base" which is much stronger, and "crystal meth" or "ice" which is a smokable crystalline derivative of methylamphetamine. As for most toxic addictive drugs, it takes strong motivation to quit, however, users should at all times take care to prevent conception since amphetamine abuse adversely affects sperm quality and in utero fetal development risking postnatal wellbeing. (See RECREATIONAL DRUGS, INTRAUTERINE GROWTH RETARDATION). (IP)
AMPHIBIA: See FROG EXTINCTIONS.
AMYGDALA: (Greek: "almond") Part of the brains limbic system, specialising in thheir lives. (See EMOTION, EMOTIONAL INTELLIGENCE) (MP)
ANABOLIC STEROIDS: Synthetic compounds with a molecular structure similar to the male sex hormone testosterone. The anabolic component promotes muscle growth and the androgenic component acts upon masculine traits in the body. They have an important function in general medical applications as; for example, in replacement therapy for men with low testosterone levels, but are also commonly illegally used as performance-enhancing drugs in dosage regimes 10 to 100 times the accepted therapeutic range. Performance enhancement is suitable for weight lifting, body building, power lifting and field events where they permit athletes to train longer and harder with improved competitiveness due to heightened aggression. Uncontrolled steroid use is damaging to health and can cause liver dysfunction and increased risk of cardiovascular disease and cancer. Unscrupulous scientists, malpractising doctors or misguided administrators can create a rationale that international success, especially in the Olympic Games, implies the use of performance-enhancing drugs where disputes surrounding the legality of some winning performances (catching "Fool's gold"). Traces can last for years (see ERYTHROPOIETIN or EPO). (IP).
ANAEROBE: (Greek: an + aer "without air" + bios "life") any microorganism which lives and grows in the absence, or almost absence, of oxygen. They are widely distributed in nature with just a few being infectious occurring, typically, in deep puncture wounds that exclude air or in tissue that has diminished oxygen-reducing potential. Common examples of anaerobic infections are gangrene, tetanus and botulism - the last a source of poisoning from improperly cooked or canned foods (see BOTULISM; ENDOTOXIN). (IP)
ANAEROBIC: A ny species which generally lives in the absence of oxygen (Greek: an + aer "without air" + bios "life"). (IP)
ANAEROBIC EXERCISE : Muscular exertion sufficient to result in metabolic acidosis resulting from accumulation of lactic acid - a product of muscle metabolism. This form of strenuous exercise should be avoided at all costs during pregnancy because strenuous physical activity results in many physiological changes that can affect the wellbeing of the fetus. Some of these changes are obvious; for example, severe exercise stimulates increased production of noradrenaline causing immediate contractions of the uterus, which may negatively affect the uteroplacental circulation and the fetus. The most serious argument against endurance sport and also prolonged immersion in saunas during pregnancy concerns the consequences of maternal hyperthermia or overheating. Animal studies have shown a consistent relationship between birth defects and exposure to high temperatures, although the data on human pregnancy and elevated temperature are not as consistent. Hyperthermia has at least four deleterious effects a) teratogenic effects of core temperatures of greater than 40 degrees C in early pregnancy have been conclusively demonstrated in animal studies b) effects of elevated temperature on oxygen hemoglobin-binding curves makes oxygen uptake by the fetal blood more difficult c) effects of increased maternal oxygen consumption due to temperature-induced elevated metabolic rate reduces oxygen availability for fetal consumption d) increased maternal blood flow to the skin for thermoregulation decreases uterine irrigation affecting placental transport of oxygen and nutrients. (See AEROBIC EXERCISE; ANAEROBIC; HYPERTHERMIA). (IP)
ANALOG : (Greek analogos 'proportionate'). 1. Likeness in appearance or function but not in evolutionary origin; for example, the insect eye and the mammalian eye - hence analogous. 2. Numerical information (as in analog computer) that is represented in the form of a quantity (usually a voltage) that varies in equal manner as the data but is convenient to manipulate mathematically. (See DIGITAL, COMPUTER). (IP)
ANALOGOUS : See ANALOG.
ANALOGY : (Greek analogia 'proportion'). In mathematics the identification of a general agreement or similarity between two problems or methods. For instance, analogy is used to indicate the results of one problem from the known results of the other. In biology the identification of a resemblance of form or function between organs essentially different; that is, not of common evolutionary origin. For instance, the wings of birds are analogous to the wings of insects. (See METAPHOR). (IP)
ANALYSIS : (Greek ana + lyein 'to loosen'). The branch of mathematics that uses the concept of limits - resolution to simple elements. In chemistry/biology the separation of substances into their constituent parts and the determination of their nature; for example, qualitative analysis determines what elements are present while quantitative analysis determines the quantity of each element. (See ANALYSIS OF VARIANCE, SCIENTIFIC METHOD, STATISTICS). (IP)
ANALYSIS OF VARIANCE: Analysis of Variance (ANOVA) is a series of statistical procedures for determining whether differences among groups of data are attributable to chance alone. A significance test, it determines whether there is a significant difference between the means of a number of treatment groups. As a common technique for comparison of two or more populations, care should be taken to coordinate experimental design with its requirements. Design considerations and elements of ANOVA include one-way ANOVA, two-way ANOVA, multi-factorial comparisons, randomized block designs, orthogonal designs, nested or hierarchical analyses, transformations of data, degrees of freedom, significance level and probability of Type I and Type II Errors. Tests for homogeneity of variance include Cochrans Test for balanced data, and Bartletts Test for unbalanced data. Analysis of Covariance combines regression techniques with analysis of variance. (See ANALYSIS, VARIANCE, STATISTICS, SIGNIFICANCE LEVEL, TYPE I ERROR, CHI-SQUARE TEST, SCIENTIFIC METHOD) (MP & IP)
A movement begun at the beginning of the twentieth century by Bertrand Russell, Alfred North Whitehead and G.E. Moore in England, by Ludwig Wittgenstein in Austria and England and by Gottlob Frege in Germany. Originally it was an extremely demanding discipline of analysing scientific and mathematical language in terms of mathematical logic. It was thought that all knowledge consists of sense experience expressed in logical form, except for mathematics which is entirely formal. Mathematics, therefore, was thought of as a branch of logic, and all mathematical truths were to be proved from axioms of logic. (Axioms of logic are obviously true contentless statements like: "Either it is or it isn't".) In 1931, however, this was shown to be a hopeless dream when Kurt Godel published a paper proving that in any logical system which is strong enough to formulate simple arithmetic, there will be true statements which cannot be proven from the axioms of the system.
While analytic philosophy was highly mathematical at Cambridge, Oxford philosophers developed the "ordinary language" school of philosophy, analysing concepts by observation of how we use words in ordinary speech. Gilbert Ryle believed, for example, that neurobiology is irrelevant to the study of the mind: we only need analyse our uses of mental words, like "think", "feel", "imagine", etc, in ordinary language. Ethics became no longer an enquiry into what is right and what is wrong but an enquiry into how we use words like "right and wrong". An offspring of this approach is today's "descriptive bioethics". But while Oxford ordinary language philosophy was highly parochial, restricting one's investigation to how English-speaking people use words, descriptive bioethics uses international surveys to try to bridge cultural relativism. (FL)
ANARCHISM: The term is often used pejoratively, with associations of violent lawlessness. But it also has positive meanings having to do with the attempt to live without government, coercion or any uniformity of practice imposed from above. In politics, the doctrine is difficult to carry out in practice when defense requires some form of governmental organization. In individual life, however, it can be more practical and some have succeeded in living quite well while ignoring government and other coercive institutions.
A bioethical attitude inspired by anarchism is one's taking care of one's own health -- carefully observing the effects of foods and lifestyles on one's health, for example -- rather than living and eating thoughtlessly and then running to physicians to get one out of trouble. In clinical ethics, an attitude inspired by anarchism would be the rejection of national or international -- or even hospital-wide -- laws or guidelines for DNR, abortion, candidacy for IVF, etc, leaving the decisions up to ward staff meetings, including doctors, nurses and social workers, together of course with patient and family. (FL)
ANCIENT WISDOM Some people think that humans are getting wiser and more ethical in every generation. Others think that we are getting less wise and less ethical. Many cultures have traditions of ancient wisdom, which is thought of as better than what we have today. Much of these traditions are based on the idea that prophesy belonged only to the ancients, because God, or the gods, only spoke to people in the old days. But there is no emphasis that this is true. It is just as likely that there be prophesy in every generation, or perhaps prophetic periods of history, followed by empty ones, which are followed by new prophesy. (FL)
ANDROID: (Greek: andros "man" + eidos "form") Pre-dating the word "robot", the term "android" was used in reference to any machine designed in the human image or constructed to imitate human actions. In contemporary popular culture, an android is a robot difficult to distinguish from human flesh and form, perhaps a cybernetic combination of biochemical and electromechanical components. (See ROBOT). (MP)
ANENCEPHALIC: Literally the condition of having no encephalon or brain (normally applied to fetuses or infants with no cerebrum). Anencephaly is the congenital absence of all or a major part of the brain. (DM)
ANESTHESIA: The partial or complete loss of sensation with or without consciousness as the result of injury, disease, or administration of an anesthetic. (DM)
ANEUPLOIDY: Refers to an abnormal number of chromosomes observed in a karyotype. The number can be either higher (presence of a trisomy), or lower (presence of a monosomy). (JA+GK)
ANGEL: A spiritual being, perhaps endowed with personality. They were extensively analysed in Jewish philosophy of Maimonides (Moshe ben Maimon) and in the Christian philosophy of St Thomas Aquinas. Although Judaism, Islam and Christianity are sometimes thought of as "monotheistic" religions, recognizing only one God, as opposed to "polytheistic" religions which have many, it is hard to find any ontological difference between the angels of the Hebrew Bible and the gods of Hinduism and Shinto. And the Bible describes the prophets as having had many interactions with angels. Indeed there are traditions both in Shinto and in Hinduism, which interpret the many gods just like Judaism interprets angels, as many different appearances of one infinite god. (The ancient Greeks and Romans, in contrast, do not seem to have had any concept of this unity.) So the distinction between monotheistic and polytheistic religions seems to disappear, making possible more toleration of diverse religions and cults as representing many different ways of approaching one infinite God (an attitude once argued for by Sri Aurobindo).
Many scientific people today doubt that angels exist. But many scientists believe in infinitely many non-physical entities, like "sets" and "numbers", whose existence has never been proved. Unlike sets and numbers, however, angels are thought of as active. But sub-atomic particles are also very active. And sub-atomic particles do not seem to be physical objects. Because if Heisenberg was right about indeterminacy then it follows that sub-atomic particles are not physical objects. For sub-atomic particles, according to Heisenberg, have no determinate (but only statistical) simultaneous location and motion. But it is part of being physical that an object, at any given time, is at a specific place with a specific (possibly zero) motion. So we have an example of scientifically recognized non-physical objects.
Socrates thought that a daemon was guiding his conscience. The 17th Century French mathematician, physicist and philosopher, Descartes, contemplated the possibility that an evil angel was confusing his thoughts, and at about the same time Milton, in England, was writing "Paradise Lost" about "fallen angels" confusing people's ethics. The idea of angels influencing our ethics may have been a way of expressing the feeling that some of our life decisions (bioethics) are neither the result of education nor of rational investigation, but are things we are driven to do by causes which we do not understand. (FL)
ANGEL DUST : See PHENCYCLIDINE HYDROCHLORIDE.
A negative emotional reaction associated with other bad feelings such as fear, disgust, shame, irritability, outrage, hostility and possibly even violence. Actions resulting from anger often have negative consequences, because the neurotransmitters/hormones (e.g. adrenaline) released during anger intensify impulsive action and cloud rational thought processes. (See AGGRESSION, ADRENALINE, FEAR, CONFLICT MANAGEMENT, EMOTIONAL INTELLIGENCE, TRANQUILITY, JOY) (MP)
ANGIOSPERM: The flowering vascular plants which dominate many terrestrial habitats such as deciduous forest, sclerophyll forest and rainforest. Class Angiospermae is primarily differentiated from the Gymnospermae by its mode of reproduction, which is via the seed, the fruit and the flower with its pistil and stamen. Angiosperms are divided into monocotyledonous and dicotyledonous plants. (See FLOWER, HARDWOODS, GYMNOSPERM) (MP)

meter. Ĺ is used to express wavelengths of light, ultraviolet radiation and sizes of molecules. (IP)
ANIMAL : A living being with a capacity for spontaneous movement and a rapid motor response to stimulation. Animals can be divided into two groups, invertebrates (animals without backbones) and vertebrates (animals with backbones). (DM)
ANIMAL CARE COMMITTEES : Institutional committees established to protect the welfare of animals used in research. A type of ethics committee that focuses on the welfare of nonhuman animals. (See also ANIMAL EXPERIMENTATION). (DM)
ANIMAL EXPERIMENTS : An experimental procedure conducted upon a non-human animal. These may be conducted for a variety of purposes, including education, medical research, cosmetic testing, product safety. There are ethics committees in many countries to regulate the experimental nature, procedure and justified purposes. (See ANIMAL RIGHTS, CLINICAL TRIALS). (DM)
ANIMAL HOUSE : A place where animals are reared and bred for experimental research, or laboratory testing, of cosmetics and other chemical substances prior to wider use. (JA+DM)
ANIMAL RIGHTS : A right is a thing to which an entity is entitled, for example, the 'right to free speech'. Traditionally only human beings have been said to possess rights and even then the term 'rights' is understood by many philosophers as having only legal currency rather than moral authority. The notion of animal rights extends rights to certain non-humans, typically those with sentience, that is, the ability to feel pleasures and pains. Those who advocate animal rights maintain that to allow humans rights but to deny them to all other species is speciesist - which is unacceptably discriminatory. There is an ethical and legal move to ascribe rights to Great Apes, and New Zealand has enacted laws which do. The UK and European Union have not enacted laws which ascribe rights to the Great Apes but it has stopped the practice of using Great Apes in medical experiments, whatever the purported benefits. (See GREAT APE PROJECT, HUMAN RIGHTS) (MR+DM)
ANIMAL TESTING ALTERNATIVES : Procedures, such as tissue culture and mathematical models, that are used in place of the use of animals in research or diagnostic laboratories. (DM)
ANIMAL WELFARE: The entitlement of animals to protection from cruelty and abuse, or to not be used solely for the benefit of humans. (See BIOCENTRIC). (DM)
ANIMISM : The belief that the boundary between human and non-human is fluid so that the things of the world, both animate and inanimate, are spirited and able to communicate or be spiritually affiliated with humans (see Dreaming). In the modern context most of us now wish to see ourselves more as a participating member of Nature by giving due regard to the interdependence of all living systems and their further dependence on physical cycles. This acknowledgment is a significant intellectual advance as it undercuts the dualistic Greco-Roman view of human and natural systems being distinct from one another and links back to ancient understandings, as substantiated in Paleolithic cave paintings at Lascaux and Altamira and the Dreamtime depictions in Aboriginal rock art. Our hunter ancestors knew Nature and its creatures (many of whom were also their deities) and respected their ethical right to exist alongside humankind. Animism probably served as an adaptive ecological mechanism by impressing a bioethical restraint upon overexploitation and abuse (see TOTEMISM & AUSTRALIAN ABORIGINAL) (IP+AG).
ANNELIDA : (Latin: ănulus 'ring') The zoological phylum containing annelid worms with an internally and externally segmented body and hydrostatic skeleton. Annelida includes the classes Polychaeta (marine worms), Oligochaeta (earthworms) and Hirudinea (leeches). (MP)
ANOMALY : See DEVELOPMENTAL ANOMALY.
ANONYMITY : Without a name. The concept is used in databases to protect the privacy of an individual sample by deleting the name, or identifiable information. The removal of the identifying information can occur before entering the storage facility, or database, or after. (DM)
ANONYMOUS TESTING : Epidemiological testing in which the source of the specimen or the person being tested is not individually identified; often used in testing for the prevalence of a disease. (DM)
ANOREXIA ATHLETICA: is an exercise addiction which often overlaps with eating disorders such as anorexia nervosa or bulimia where the cycle of forced, prolonged exercise (swimming, running, dancing) and decreasing food intake forms the basis of activity anorexia. In order to maintain an adequate energy balance, caloric needs for non-essential bodily functions; such as reproduction, are suppressed. In the human context, anorexias may have resulted from natural selection favoring those individuals who become active in times of food scarcity as stopping to eat is negatively balanced against reaching an area where food may be abundant (see ANOREXIA NERVOSA; BULIMIA NERVOSA; OBESITY). (IP)
ANOREXIA NERVOSA: (Greek: a + orexis 'no appetite') An eating disorder characterized by a prolonged revulsion to eating resulting in emaciation, loss of periods, and emotional disturbance concerning body image and fear of becoming obese. The cause of thinness cannot be attributed to a primary endocrine (hormonal) disorder but the conditions of anorexia nervosa, bulimia nervosa, emotional deprivation and calorie restriction can cause secondary endocrine abnormalities; such as delayed or absent puberty and infertility. The condition is primarily a maturational problem in adolescents who, in the majority of cases, come from dysfunctional family homes. For example, a significant proportion of patients with eating disorders were sexually molested by a family member or friend during childhood, or who associated eating with emotional distress, conflict and anxiety states (Greek a + orexis meaning no appetite) (see BULIMIA NERVOSA; ANOREXIA ATHLETICA; OBESITY) . (IP)
ANOVA: see ANALYSIS OF VARIANCE.
ANOSMIA : (Greek a + osme 'without smell'). 'Odor blindness' - the total loss or impairment of the sense of smell. Anosmia may be temporary resulting, for example, from an obstructive respiratory infection or a blow on the head which may damage the olfactory receptors, or be permanent as a result of an irreversible damage to any part of the olfactory apparatus. Sometimes anosmia (the so called specific anosmias) does not involve a total loss or reduction of the sense of smell but is instead specific to particular substances; for example, 3% of the population has trouble smelling the odor of sweat, 12% have diminished sensitivity to musky odors. It is important to note that anosmia may be induced by injuring the olfactory receptors consequent to inhaling caustic substances such as lead, zinc sulfate, or concentrated matter such as cocaine. (See OLFACTION, SENSES). (IP)
ANTARCTICA : The continent at the South of the planet Earth, where the South Pole is located. A landmass covered with ice, up to several km thick, because it is below freezing. The Antarctic Treaty is an international treaty against commercial exploitation of the mineral resources of this continent, intended to prevent pollution. Many nations have research bases on he continent, and some claim territory of Antarctica or islands off its coast. (DM)
ANTE- : Prefix denoting before in space or time. (See PRE-, ANTI-) (MP)
: See PRENATAL DIAGNOSIS.
ANTHRAX : One of the powerful bacterial biological weapons Bacillus anthracis occurs in many different strains as skin and inhalation strains, stable in spore condition, on contact it multiplies, its toxins cause hemorrhage leading to death. (JA)
ANTHROPIC PRINCIPLE: (Greek: anthropo human) Cose exiandon Carter and developed in John Barrow and Frank Tiplers The Anthropic Cosmological Principle . (See OMEGA POINT THEORY, PARALLEL UNIVERSES THEORY, HOLOGRAPHIC UNIVERSE THEORY, ANTHROPOCENTRIC) (MP)
A belief, doctrine or attitude in which the Universe is regarded as centered around humankind and organized in terms of human values). Anthropocentrism has been fostered by religious beliefs, placing human beings at the center of Creation, until scientific theories laid down by Darwin, Wallace and other naturalists in the mid-XIX
century have demonstrated that all living beings have common evolutionary roots and share mutual interdependence relationships, including our species. Bioethics based on anthropocentric views overlooks the many issues in which other species are involved, centering its attention only on human beings. ((see BIOCENTRIC). (IP, GK).
ANTHROPOLOGY: (Greek, Anthropo : man) The study of humans, regarded as the most scientific of the humanities and the humanity of the sciences. Study of human origin, social development and political organization, language, religion and art. (JA)
ANTHROPOMORPHISM: (Greek: anthropos "man" + morphe "form") The attribution of human qualities to animals, inventions and other non-human objects or organisms. Although animals may not display properties related to human intelligence, they may have variations on other human qualities such as emotions and feelings like sadness or pain. (MP)
ANTHROPOSPHERE: (Greek: anthropo "human" + sphaira "globe") The realm of human activity and infrastructure, a rapidly growing component of the biosphere. The anthroposphere has an input of materials and natural resources, and outputs a flow of waste materials. (See BIOSPHERE) (MP)
ANTI- : Combining prefix denoting against, reverse or in opposition to. (See ANTE-, MAL-, PSEUDO-, META-) (MP)

ANTIBIOTIC: (Anti=against; bios = life) Anti = against, bios = life, substances produced by plants/animals/microbes which can kill microbes or inhibit their growth. Synthetically produced to stop microbial infection. (Bioactive compounds)(JA)
ANTIBIOTIC RESISTANCE : The ability of microorganisms to adapt and survive high concentrations of a normally lethal antibiotic. The resistance is acquired by the natural selection of resistant mutants in the presence of low concentrations of this antibiotic; however, the production of resistant strains of microorganisms can also be artificially created by means of genetic technology. Antibiotic resistance is often an accidental result of medical overprescription. Another reason is the environmental release of large quantities of antibiotics which are added to the feed of factory-farmed animals. The accidental acceleration of antibiotic resistance generates an urgent race to create new drugs for combating human disease. (See ANTIBIOTIC, ANTIBIOTIC OVERPRESCRIPTION). (IP+MP)
ANTIBIOTIC OVERPRESCRIPTION : The overuse or overprescription of antibiotic drugs may result in the accelerated adaptation of resistant strains of microorganisms in the patient and the environment. Hospitals are one of the more common breeding grounds for antibiotic resistant bacteria. Antibiotics are often considered a generic treatment, and in many less developed countries are generally sold over the counter without a prescription or specialist advice. Careless use of antibiotics may also have other side effects, such as the death of useful symbiotic bacteria in the gut, or damage to the structure and function of the ear. For example, antibiotics called aminoglycosides (neuromycin, kanamycin, dihydrostreptomycin and vancomycin) may irreversibly damage hearing by attacking the hair of the cochlea, while streptomycin and gentomycin may affect coordination and balance - if continued, nerve deafness may occur. (See ANTIBIOTIC, ANTIBIOTIC RESISTANCE). (IP+MP)
ANTIBODY : Immune related protein produced by the body in response to a specific antigen. A blood protein (immunoglobin) produced by white blood cells in response to the presence of a specific foreign substance (antigen) in the body, with which it fights or otherwise interacts. Antibodies recognize thousands of different antigens through their highly variable antigen-binding regions, and interact with leukocytes and/or complement components to destroy the antigen. Antibodies to sperm, if present, can impair fertility by causing agglutination of sperm. Antibodies against natural components of the body can also be generated, inducing an autoimmune response and subsequent destruction of the tissue (i.e. in insulin dependent diabetes mellitus, lupus erythematosus or rheumatoid arthritis). (DM+GK+JA)
ANTICODON : Complementary to the codon of triplet code on a tRNA attracted to a complementary codon on mRNA. (JA)
ANTICOPYRIGHT: A term referring to new publications which are legally open to duplication and distribution to the widest possible audience. Poor nations are those most in need of ethical, environmental, social and medical information and resources. Anticopyright status may only be limited to poorer nations or non-profit organizations, in order to maintain economic incentives. Activist and subversive literature often bears an anticopyright label, and the internet has provided a free platform for many of the scientific and medical journals. (See COPYRIGHT, ANTI-PATENTING) (MP)
ANTIDEPRESSANT DRUGS : Drugs for the treatment and control of depressive illness. There exist three major groups of antidepressant drugs the monoamine oxidase (MAO) inhibitors, the tricyclic antidepressants and the latest generation serotonin re-uptake inhibitors. The latter are favored for their selective action, since the tricyclics affect a broader range of neurotransmitter systems, and MAO inhibitors can potentially interact dangerously with certain food constituents. Lithium is also used to treat bipolar disorder (manic depression), and various herbal remedies (e.g. St. Johns Wort) are also used to combat depression. (See SEROTONIN RE-UPTAKE INHIBITORS, PROZAC, LITHIUM, MONOAMINE OXIDASE, BRAIN NEUROTRANSMITTERS). (IP+MP)
ANTIDOTE: A drug which neutralizes poisons and their effects. Antidotes may react chemically to produce harmless compounds, act mechanically to prevent absorption, or perform physiologically to produce opposite effects to the poison. Usually the stomach should also be pumped to remove the poison (and the occasionally toxic antidote), however not when this may cause damage in patients who have ingested caustic agents. (See POISON) (MP)
ANTIGEN : A foreign protein/polysaccharide, initiates immune response to form antibodies specific to it. (JA)
ANTI-GLOBALIZATION MOVEMENT: A global collective of concerned people remarkable for its breadth and diversity, including workers groups, industrial unions, human rights advocates, social workers, ethicists, environmentalists, socialists, anarchists, anti-capitalists, the anti-war movement, green movement, advocates of fair trade, forgiveness of third world debt, anti-patenting of pharmaceuticals/genes, workers rights and ecology, including people from mainstream society in both the developed and developing worlds. Commentators on the globalization debate in no particular order include George Monbiot, Susan George, Edward Herman, Naomi Klein, Anita Roddick, Ralph Nader, Charles Handy, John Ralston Saul, Francis Fukuyama, Samuel Huntington, John Micklethwait, Lester Thurow, Noam Chomsky, Michael Albert, Michael Moore, David Ransom, John Pilger, Vandana Shiva, Maria Mies, Joseph Stiglitz, David Pearce, Hunter Lovins and others. The anti-globalization movement dramatically increased its presence in the media and public consciousness with the 1999 Seattle protest gathering during the World Trade Organization conference, marred by rioting and security clashes. One section of the anti-globalization movement believes that any system which has lost control of whats good, freedom, justice, human rights, responsonal trade agreements and global institutions (f sustainable development, global equity and etOBEDIENCE, PROTEST, PROGRESS, GLOBAL VILLAGE) (MP)
Drugs which block the histamine receptors of cells to prevent allergic response. Antihistamines are used to treat allergic rhinitis (hay-fever), allergic rashes, asthma, and the common cold. Side effects may include sleepiness, dizziness and dry mouth. (See ANTIBIOTICS) (MP)
ANTIMISSILE: A missile or other defensive measure, which involves the interception and destruction of attacking enemy missiles. (MP)
ANTIOXIDANTS : are substances which delay the oxidation (spoilage) of matter, for example, raw vegetable oils contain natural antioxidants which reduce the speed of deterioration. Antioxidants are deliberately added to prepacked foods and drugs in order to delay degradation by oxidation and increase their shelf-lives. The consumer is often led to believe that vitamin supplements having antioxidant properties should be taken daily, however, the rationale for daily use of such products has not been established. In general, healthy adult men and non-pregnant women consuming a normal varied diet do not need vitamin supplements. (See VITAMINS; FREE RADICALS). (IP)
ANTI-PATENTING: A term referring to the movement against the patenting of products which increase environmental quality and social wellbeing. Products designed for sale in the developed world can be beyond the economic reach of people in less developed nations, for example drug patents prevent equitable availability to those living with HIV or dying of other diseases. The free or economically-scaled release of such bioethical products should be encouraged and subsidised. (See PATENT, ANTICOPYRIGHT) (MP)
ANTIPSYCHOTIC DRUGS : Drugs used to treat severe mental illnesses such as aggressive psychosis, schizophrenia, bipolar disorder, mania and severe depression. They usually normalize the action of dopamine and possibly other neurotransmitters. Although antipsychotics can save people from the need for incarceration, they may have serious side effects such as dyskinesia (tremors), ataxia (staggering), seizures and lethargy. It is perhaps well to bear in mind that one-third to one-half of psychotic patients improve symptomatically - or show constructive personality change - without prescribed medication. When assessing drug effectiveness care must be taken to include adequate control groups - either untreated or treated by another type of therapy in order to avoid possible long-term risk. (See COGNITIVE BEHAVIORAL THERAPY, LITHIUM). (IP+ MP)
'ANTISENSE' RNA: RNA that is complementary to the nucleotide sequence of normal mRNA. It therefore forms a duplex with the mRNA preventing the mRNA being used in protein synthesis, thus indirectly controlling gene expression. (DM)
ANTI-REDUCTIONISM: Reductionism, a doctrine deriving from Auguste Comte, says that "higher-level" sciences can always be reduced, ie explained in terms of "lower-level" or more fundamental ones. Thus sociology is explained in terms of psychology, which is explained in terms of physiology, which is explained in terms of biology, which is explained in terms of chemistry, which is explained in terms of physics, which is explained in terms of mathematics. Thus all history, international relations, human relations and our mental and emotional lives are really matters of particle physics formulated mathematically. Genetic Reductionism is just a special case of reductionism explaining human life in terms of molecular genetics.
Anti-Reductionism has been formulated in terms of a number of different arguments: (I) "Not even all clinical phenotypes can be attributed to single genes, so obviously not all personality types or patterns of human action can be attributed to single genes": to which the answer is that genetic reductionism need not be single-gene reductionism, but can explain each phenotype in terms of multiple genes. (II) "Human characterists, including clinical disease, are rarely explainable in terms of genetics alone. There are also environmental -- including nutritional and educational -- co-factors.": to which the answer is that while the objection may refute Genetic Reductionism, it does not refute Reductionism in general, because maybe environmental cofactors may eventually be explained in terms of mathematical physics. (III) "Reductionism leads to the denial of free will": to which the answer is that this begs the question. Maybe free will is just an illusion anyway. (IV) "Reductionism has never been proved. Has anyone ever shown how we can really explain international relations as events on the subatomic level?": to which the answer is that we need patience. Let's see how science develops, in the meantime leaving Reductionism as an open possibility. (V) "Reductionism takes the spiritual out of life, by making everything mathematical physics." To which the answer is that maybe subatomic particles are less material and more spiritual than we have thought, as explained in the entry ANGELS (q.v.) (FL)
ANTI-SEMITISM: Semites are a loosely interrelated group of populations speaking similar languages, including Hebrew, Arabic, and such Ethiopian languages as Geez, Amharic and Tigrinya. But "Anti-Semitism" usually means the hatred of Jews. Anti-Semitism was a central doctrine in Nazi ideology. (FL)
ANTISOCIAL: Antisocial behavior conflicts with societal expectations, and may range from harmless eccentricity, through rudeness and negativity, to aggressive or psychotic behavior. (See ASOCIAL) (MP)
ANTIVIVISECTION: A movement against invasive experimentation or teaching using live animals. Nowadays, the movement has taken more moderate forms, such as the Fund for the Replacement of Animals in Medical Experimentation, which teaches the "Three R's": Replacement (of animals with tissue cultures and computer modeling), Reduction (of the number of animals used in each trial), and Refinement (of experimentation by less painful methods). The publish a scientific journal called Alternatives to Laboratory Animals , and other journals also exist. (FL)
ANTI-WAR MOVEMENT: See PEACE MOVEMENT
) anticipation of impending dread, danger or misfortune not associated with an apparent stimulus and accompanied by tension, restlessness and other adrenaline-generated physiological symptoms such as increased heart rate, throat tension, gut cramps, tremors, cold sweats and insomnia. Psychological symptoms are subjective and often "free-floating". Typical signs of psychological distress include irritability, sensitivity to constructive criticism, uneasiness about the future, feelings of uncertainty and helplessness, unconscious conflict regarding lifes essential values and goals. Anxiety disorders are complex and may take different forms (generalized anxiety, separation anxiety, panic anxiety, situationalgical variables. Anti-anxiety drugs (anxiolytics), by helping to control the physiological symptoms, provide relief. The definitive treatment, however, restsr example changes in health, self-concept or environment, maturational crises or subconscious conflicts. Anxiety differs from depression, but is typically liee FEAR, ANXIOLYTICS, DEPRESSION, GENERAL ADAPTATION SYNDROME). (IP+MP)
ANXIOLYTICS: Anti-anxiety drugs, including sedatives and minor tranquillizers, used temporarily to treat panic and anxiety reactions in conjunction with counseling to address related underlying life-factors. (See ANXIETY) (MP)
ANZECC : Australia and New Zealand Environment and Conservation Council.
APARTHEID: A political system in which people of different races are separated. In the past in South Africa for much of the twentieth century. (DM)
APATHY: A state of not caring; not wanting to know; complacency; indifference; to ignore; disinterested in contemplation; anesthetized by popular culture; a postmodern intellectual narcosis; compassion fatigue; too lazy; too busy; self-indulgence; limited choices in work and leisure-time; non-reflection, non-deliberation and subconscious blocking of distressing information. Apathy is less ethically excusable than ignorance. Apathy implies at least subconscious knowledge of the truth - if those who know will not take action, then those who dont know certainly wont, and those who are the subject of oppression or ethical concern usually cant. (See IGNORANCE, UNCERTAINTY) (MP)

APOCALYPSE : The end of the world. (DM)
APOPTOSIS : (Greek: apo 'away' + ptosis 'falling') Programmed cell death is the mechanism whereby damaged, malfunctioning or unnecessary cells can be removed from the body. All animal cells carry an intrinsic genetic "death" program which is important in growth and development, and in the repair and maintenance of mature body tissues. Apoptosis is not a cause of aging; however defects in this system may contribute to age-related processes (Greek apo meaning away and ptosis falling). (IP)
APPLIED ETHICS: If theoretical ethics studies the meaning of ethical terminology and the foundations of ethical thinking, applied ethics studies the application of ethical reasoning in real life. The distinction is the same as that between Foundational Bioethics (studying the foundations of bioethical reasoning in culture, spirituality, religion, law and philosophy) and Applied Bioethics (including clinical medical and nursing ethics, environmental ethics, research ethics, etc.) There is a philosophical journal called Applied Ethics . (See APPLIED MATHEMATICS, APPLIED PSYCHOLOGY) (FL)
APPLIED MATHEMATICS : The study of the mathematical techniques used to solve problems; that is, the application of mathematics to existing systems. (See APPLIED ETHICS, APPLIED PSYCHOLOGY). (IP)
APPLIED PSYCHOLOGY : That part of psychology which places its knowledge to effect in practical situations. Important branches of psychology which emphasize practical rather than theoretical approaches are educational psychology, clinical psychology, child psychology and industrial/occupational psychology. (See APPLIED MATHEMATICS, APPLIED ETHICS). (IP)
AQUABOT: Aquatic robots, or autonomous underwater vehicles. These small devices can navigate in three dimensions and use sensors to collect oceanographic data, carry out underwater mapping, measure effluent pollutants, gather military intelligence or sweep mines. Future generations of aquabots may be schooled to create a moving sensor array, and of course may also potentially be weaponized. (See ROBOT) (MP)
AQUACULTURE : (Latin: aqua 'water' + culture) A form of agriculture where plants and animals are cultures in farms in fresh water bodies. When seawater is used then it is called mariculture. In fish farming areas fishes like Tilapia and other commercially valuable fishes can be cultured. In a marine ecosystem shell fishes like Perna viridis (green mussel) oysters are cultivated as a commercial enterprise. (JA)
(1225? -1274) : The greatest of the medieval
philosophers, canonised as Saint Thomas by the Catholic Church. His philosophy is called
were Catholics who were known for their detailed, logical debates, often dwelling on fine and seemingly sterile distinctions to the point that they have been accused of "hair splitting". It was joked about them that they would debate for years about how many angels could dance on the point of a pin. The joke is unfair. Aquinas' detailed method of question and argument did not always lead to results. But -- like mathematical games -- it engendered habits of careful and penetrating logical thinking, which became part of the European intellectual tradition.
Following the example of the Guide to the Perplexed of MAIMONIDES (q.v.), whose influence Aquinas sometimes acknowledges, Aquinas interpreted the Bible according to Aristotelian philosophy. Although this practice was at first objected to by other Church authorities, it eventually became so embedded in European Christian culture that disagreeing with Aristotle was considered to be at least as heretical as disagreeing with Jesus. This attitude remained until criticised by the mathematical and scientific philosophers of the Seventeenth Century, like Rene Descartes, and by the Protestant Reformation.
Aquinas was also familiar with Arabic philosophy, and disagreed with European followers of Ibn Roshd, who were referred to as the Latin Averroists. In his tract , On the Unity of the Intellect against the Averroists , Aquinas attacks Siger of Brabant. In the Aristotelian philosophy, that element of the soul, which is responsible for intellectual understanding, is called the Agent Intellect. Aristotle thought that the agent intellect is eternal. Ibn Roshd accepted this idea, and argued that there is only one agent intellect, which is shared by all humans. Maimonides' doctrine seems to have been similar, as he refers to the agent intellect as an angel. Siger of Brabant, however, went further and argued that the passive elements of intellection are also common to all humans. This is tantamount to monopsychism, the doctrine that there really is only one soul, in which we all share. This made Aquinas quite angry, because it seems to provide a philosophical basis for forgiving sinners too easily. For, as Latin Averroists seemed to believe, if Saint Paul's soul is saved, and if my soul is the same as that of Saint Paul, then my soul is already saved as well. So even if I sin all I like, I will get to heaven. Aquinas' On the Unity of the Intellect is a polemical diatribe against this doctrine. But monopsychism seems bioethically appealing nonetheless. It seems to affirm the unity and solidarity of all humans, encouraging love. And why shouldn't we welcome reasons for forgiving people? (FL)
Aquinas' Doctrine of Double Effect has had considerable influence on bioethics. It says that it is permissible to do an act which produces an unethical effect, when the act is performed with the intention of achieving another effect which itself is ethical. The unethical effect may be foreseen, but it must not be intended. Thus, priests have permitted birth control pills if the intended effect is to regulate the menstrual period, and not to prevent conception. The doctrine is used to permit giving patients high doses of opiods like morphine or heroin, even if death is a foreseen result, when what is intended is not death but relieving pain. This application of the doctrine has been hotly debated. (FL)

ARISTOTLE (c. 384-322 BC) Perhaps the most famous of Greek philosophers, he influenced Islamic, Jewish and Christian philosophy. Author of works on logic, philosophy, natural science, ethics, politics and poetics. He believed in living according to a "middle road" between extremes (an idea which is also found in Buddhist writings, leading to the question whether it began in Greece or much farther East). He thought that the most ethical life is the life of intellectual activity, in which we become most similar to and beloved by the gods. His main ethical works, the Nicomachean Ethics and the Politics, were the crowning finale to a massive corpus including logic, scientific method, philosophy of mathematics, physics, biology and metaphysics. This raises the question whether todays specialized BA, MA and PhD programmes in ethics are the best way to educate bioethicists. Perhaps they should start with more science and substantive philosophy, like Aristotle.
Aristotle said that it is a mark of maturity not to seek more precision than one's subject can allow, and that ethics -- more of an art than a science -- is incapable of the degree of precision which mathematics and physics allow. This implies harsh criticism for philosophers like the utilitarian, Bentham, who sought an ethical calculus which would give definitive answers to questions, as well as for those who try to quantify ethics through statistical surveys. (FL)
ARITHMETIC : The study and the understanding of the structure of the number system and the skills necessary to manipulate numbers in order to solve problems.

ARTIFICIAL: Created, produced or imitated by humans. Not occurring in nature, or not the genuine article. Artificial creations such as new chemical products, newly designed drugs or genetically modified organisms may have unpredictable effects on biological or ecological systems, as they have not been tested by any previous evolutionary process.

a synthetic membrane that is stitched in place to seal the vagina before the marriage ceremony. The operation is practiced in cultures where virginity (virtue) at marriage is regarded as desirable or even mandatory. (IP)
ARTIFICIAL INSEMINATION: The introduction of sperm into a woman's vagina or uterus by noncoital methods, for the purpose of conception. The procedure is done either with semen from an anonymous donor (artificial insemination by donor or AID) or from semen provided by the partner or husband (artificial insemination by husband AIH). AID is recommended when the partner is infertile or in cases in which he is a carrier of a serious genetic defect. Assuming normal fertility in the female, tested donor semen results in a pregnancy in 70% of the cases and is, therefore, one of the major treatments for male infertility. The procedure does not carry an increased risk of spontaneous abortion or congenital anomalies. AIH has a much lower success rate but is useful in cases of paraplegia (sperm is collected by electroejaculation), obstructed vas deferens or epididymis (sperm is aspirated from the epididymis) and forced separation of couples (prisoners on long-term sentences). AI as a technique has been practiced for centuries as a tool in livestock production and its application has been broadened to include conservation programs for endangered species. The first recorded human birth after AIH was in 1790 when the Scottish physician John Hunter inseminated a woman with epididymal sperm from her husband who had urethral defect (see artificial insemination by husband, ASSISTED REPRODUCTIVE TECHNOLOGY). (IP, DM)
ARTIFICIAL INSEMINATION BY HUSBAND : The procedure is used in cases of paraplegia, obstructed vas deferens or epididymis and forced separation. It is also used widely for idiopathic (cause unknown) infertility. Between 15-30% of women become pregnant during six insemination (menstrual) treatment cycles, significantly less successful compared with donor insemination purporting a reported 60% birth rate after six insemination cycles. (See ARTIFICIAL INSEMINATION, DONOR INSEMINATION). (DM+IP)
ARTIFICIAL LANGUAGES: Many artificial or auxiliary languages have been invented and used to facilitate international communication and understanding. These have included Volapük (World language 1880), Esperanto (Lingvo Internacia 1887), Idiom Neu986). Natural languages have been modified or simplified, for example Latino Sine Flexione (Latin without inflections) and BASIC English ('British American Scientific International Commercial English') with its selective 850 word vocabulary. Other languages have evolved (e.g. slang and jargon), merged (e.g. pidgins and creoles), been developed by necessity (e.g. sign language and shorthand) or for specialized purposes such as computer programming (e.g. Basic, Pascal and Java). Other artificial languages are just plain fun, for example Solresol ('Langue Musicale Universelle'), whose syllables are based on the musical tones such that it can be spoken, sung or played. (See ESPERANTO, PIDGIN, LINGUISTICS, SEMIOTICS, MULTIMODAL COMMUNICATION, TRANSLATION SOFTWARE) (MP)
Artificial Intelligence (AI) is the computer modeling and software simulation of human intelligence and other mental processes. Such intelligence would include holding a conversation, problem-solving, thought processing, object manipulation, playing chess, writing stories, translating, speech recognition, pattern recognition (vision), interactivity and learning. Current commercial AI has been slow to match the science fiction dreamers in simulating human mental functions. However, the evolution of technology is accelerating and tends to progress in sudden surges. Expert Systems and Decision-Support Systems are the practical application of AI research. They are used for solving problems and making decisions in a particular domain, for example Cyc is inn of AI. Bionics, cybernetics and the cyborg are medical applications of AI. Combination of all these technological features of intelligence is called the top-down approach to AI, whereas the bottom-up approach is the endowment of Artificial Life with the powers of replication, adaptation, learning and self-evolution. Popular science fiction such as Hollywoods
have presented the possibility of the human species being superseded by the evolution of artificial intelligence. Despite skepticism, scientific risk-analysis and ethical debate is required because of the extreme consequences to humanity from such a scenario. Scientific and philosophical debate has not been able to rule out the possibility of silicon-based life - works such as
The Emperors New Mind
by Roger Penrose which have tried to refute the possibility have had their assumptions criticized. It seems that certain thresholds or previous limits to the creation of artificial intelligence are likely to be breached by advances in quantum computing, nanotechnology and/or molecular electronics. These advances combine immense increases in processing power with the replication and manipulation of molecules and atoms, and add carbon (organic molecules) to the traditional silicon of microcircuits. Whether or not all definitional requirements for life or intelligence are met, something much
these things is on the technological horizon. Even today, non-sentient information databases and other computerized technology are taking over our daily transactions whether individually (automated workplace, privacy, Big Brother) or collectively (over-reliance on technology).

ARTIFICIAL LIFE: Software and hardware which has similar characteristics to living organisms. The top-down approac out to be quite cute, for example the camera and gyroscope-faced Cog and Kismet, or the insect-like heat-sensing six-legged Genghis… but endowed with artificial intelligence in a terrain of unmanned vehicles and autonomous weapons it is a different story. The opposing mode of research into artificial life is the bottom-up approach, which allows artificial life to create itself through the powers of evolution. Using nature as the model, programs such as genetic algorithms and cellular automata are created with. Examples of ear internet, with iintranets and firlar electronics atween natural selection in organisms/cells and that of cellular automata is that biological evolution selects among random variations, whereas variation in artificial life may be heuristically directed . The potential ethical danger from this is that artificial life can evolve at an incredibly greater speed than any biological system. The internet provides a very difficult-to-control habitat with a rich informational database, and could perhaps eventually support a very diverse form of cyber-ecology or central intelligence.

ARTIFICIAL NEURAL NETWORKS:
Computational models which emulate biological neural networks. Artificial neural networks contain components and functions analogous to neurons, for example the processing element (nucleus), network node (soma), inputs (dendrites), output (axon) and signal weight (synapse), though without all of the layers of complexity of biology. Artificial neural networks are associative memory systems using inductive reasoning, self-organization and parallel processing similar to the human brain. They are driven by data, and function by scanning many case studies for common patterns. They can function despite the presence of ambiguity by using induction, associative memory or fuzzy logic.

ASHKENAZI JEWS : "Ashkenaz" means Germany in Hebrew and "Sefarad" means Spain. In popular language Ashkenazi Jews are those whose ancestors lived during the exile in Northern Europe, while -- because many Spanish Jews fled eastward after the expulsion of the Jews from Spain in 1492, Sefaradi Jews are thought of as those from North Africa and the Middle East. But this is a misconception because many Spanish Jews fled to Northern Europe after the expulsion, and many so-called Ashkenazi Jews are descended from them. Also, many North African and Middle Eastern Jews are descended from families who were never in Spain. These include most notably the "Bavlim" (Babylonians) who were in Iraq since Biblical times, the Yemenites, who were in Yemen since Biblical times or shortly thereafter, and Israeli families who have been in Israel continuously since Biblical times. There are also communities who were never either in Europe or the Middle East before they immigrated to Israel. These include the Ethiopian community, and the Kochinim (from Kerala in Southwest India) who were in their exilic homelands at least since the time of the Second Temple.
Ashkenazi Jews are often mentioned in genetic medicine because of a number of genetic diseases -- notably Gaucher, Tau-Sachs and breast cancers -- which occur particularly frequently in this population, and have attracted much research interest. (FL)

ASPHYXIA: (Greek: a + sphyxis 'without pulse') Severe reduction of oxygen in the blood resulting in loss of consciousness and, if not reversed, death. Causes can be varied; for example, drowning, inhalation of toxic gas or smoke, poisoning and blockage of respiratory tract. The condition is of specific concern in some newborns where it may develop during labor or immediately after delivery due to, for example, prematurity or the effects of anesthetics and analgesics (Greek a + sphyxis without pulse) (see INTRAUTERINE GROWTH RETARDATION and HYPOXIA). (IP)
ASPHYXIATION : (Greek a 'without' + sphyxis pulse). Suspension of breathing due to an abnormally low oxygen concentration in the lungs. The condition may be brought about by a) obstruction to the passage of air to and from the lungs as in drowning, presence of foreign bodies/malignant growths in the air passages, b) insufficient oxygen supply in the air, c) poisonous (asphyxiant) chemical substances causing suffocation. Whatever the cause severe hypoxia, if not corrected quickly, leads to hypoxia risking brain damage, irreversible paralysis and ultimately death. (See HYPOXIA). (IP)
ASPIRIN : Acetylsalicylic acid (C 9 H 8 O 4 ) probably the most widely used over-the-counter analgesic bought for headache, dental pain and symptomatic relief in flu. It has been the mainstay of pain relief for 100 years but despite this its mechanism of action is not fully understood, however, it seems to reduce pain by acting on blood platelets which are involved in the process of inflammation. For this reason aspirin is also a mainstay in arthritis and is valuable in forestalling heart attacks; however, it does not offer heart-attack protection. Aspirin is the standard against which other non-steroidal anti-inflammatory drugs are measured. It is important to take the medication with food to prevent gastrointestinal irritation. (See ANALGESIC; CORTICOSTEROIDS). (IP)
ASSASSINATION: (Assassin from Arabic hashshashin 'hash eaters') The surprise murder of a prominent political or public figure for the purposes of making a statement or otherwise changing the course of human events. Rightly branded as terrorism during times of peace, assassination may become common practice during times of war. National non-assassination policies should be encouraged, especially in Western democracies. International systems of justice and intervention should be empowered to provide just and legal alternative means. (MP)

Almost all thought processes and knowledge are based upon some assumptions. (See AXIOM, THEORY, HYPOTHESIS, CONJECTURE, PREMISES) (MP)
ASTHMA : Asthma, or a pathological shortness of breath, can be treated by various drugs. MAIMONIDES(q.v.) in his medieval Treatise on Asthma, maintained that it can be treated psychosomatically, by calming the mind. One of the authors of this dictionary has cured himself of an addiction to an asthma inhaltor of over twenty years, by combining breathing from Yoga and from Japanese martial arts. He inhales through the mouth, for a count of seven, drawing the air down to the "tanden", w h ich is the centre point between the naval and the pubic bone, and allowing the air to expand the lower abdomen. Then, without releasing any air, he switches to breathing in through the nose, again for a count of seven, but this time expanding the chest a nd (imagining the chest to be open at the bottom like an upturned barrel) drawing air up from the tanden into the upper chest. He then holds his breath for a count of seven, and then while counting again to seven, releases it through the nose. He does t his excercise while standing and raising his arms higher, and higher, in order to open the chest as much as possible. He also does it while sitting in Japanese "seiza" position, either raising the arms, or simply letting them rest on his lap. This metho d has not yet undergone controlled clinical trial.

ATMOSPHERE: The envelope of gases and particles surrounding the Earth, within which are maintained homeostatic conditions for life. Environmental indicators for the atmosphere usually concern air quality or climate. The troposphere is the lower atmosphere up to about 20km, in which minor gases, particles, water vapour and carbon dioxide have a significant effect and where most weather takes place. The stratosphere is from about 20-50km and contains much of the ozone layer. Above that are the mesosphere and thermosphere before the vacuum of space. (See GLOBAL WARMING, GREENHOUSE EFFECT) (MP)
ATMOSPHERIC POLLUTION : See AIR POLLUTION.
ATOM: The atom is the building block of matter. An atom is composed of positive protons and non-charged neutrons in its nucleus, surrounded by shields of negative electrons. All atoms of an element are different from the atoms of another element. The atomic number of an element is its positive charge - the number of protons in its atoms. The protons and neutrons are composed of different types of quarks. Atoms can emit energy and radiation. (See ATOM BOMB, ELEMENT, QUARK) (MP)
ATOM BOMB : Bomb in which the explosive power, measured in terms of equivalent TNT, is provided by the nuclear fission of material such as 135 Uranium or 239 Plutonium. The bombs dropped on Hiroshima and Nagasaki was of this type. The most tragic moment in human history was fifteen minutes past eight on the morning of August 6, 1945 when the first atom bomb ever was dropped on the earth and exploded above Hiroshima city. That one explosion reduced the entire city to ashes and 247,000 lives were instantly wiped out. Gamma rays and neutrons produced by atomic explosions penetrate deeply into animal tissues causing immediate death or delayed effects, known as radiation sickness, observed as internal bleeding, vomiting, diarrhea and skin lesions which may become evident months after exposure. Moreover, the offspring of those exposed to radiation may be affected by harmful mutations that can reappear in future generations. The post-war Japanese constitution completely renounces war and advocates permanent peace for the world something that had never been done before in the history of humankind. The Japanese people accepted the Potsdam Declaration in a spirit of repentance for the destruction and misery inflicted upon a large number of human beings by the militaristic Japan of the war years.

ATTENTION-DEFICIT HYPERACTIVITY DISORDER (ADHD): is the latest term designating a chronic disorder that begins early in childhood and is manifested by problems of awareness, difficulty with attention, excessive motor activity (hyperactivity) and poor impulse control (impulsiveness). It is among the most common causes of behavioral disturbances, estimated to affect 3-5% of school-age children with highest risk in boys. Symptoms associated with ADHD (although not called this at the time) were first described in 1902 by British pediatrician George Still. Still, correctly, suggested that behaviors he had observed amongst certain children in his practice were not caused by bad parenting but a subtle unidentified brain injury. Recent evidence points to a brain-based biological disorder where a possible genetic predisposition is activated by stressful environmental factors. Environmental factors such as hypoxia, pre-, peri- and postnatal trauma have been implicated, as has exposure to toxic substances such as alcohol, cocaine, nicotine, marijuana and lead. ADHD individuals have lower than normal levels of selected neurotransmitters, dopamine in particular, which means that the brain will metabolize more slowly. (See BRAIN NEUROTRANSMITTERS, RITALIN HYDROCHLORIDE). (IP)
AUGUSTINE: (354-430, Numidia), also called Saint Augustine of Hippo, original Latin name was Aurelius Augustinus. Was one of the Latin Fathers of the Catholic Church, one of the Doctors of the Church, and is considered by many as the most significant Christian thinker after St. Paul. Augustine 's adaptation of classical thought to Christian teaching created a theological system of great power and lasting influence. His numerous written works, the most important of which are Confessions and City of God , shaped the practice of biblical exegesis and helped lay the foundation for much of medieval and modern Christian thought. More than five million words of his writings survive. He adapted Platonic tradition to Christian concepts. (DM)

AURA: An aura is a kind of light which seems to surround human beings. It may also surround animals, plants and even inanimate objects. Kirlian photography, invented in Russia, seems to be a method to photograph auras. People may have varying degrees of ability to see auras, or to read their meanings. The halo, seen in Christian and Buddhist religious paintings, seems to have been an aura, representing the strong light which highly spiritual people seem to project. The lehat, or light surrounding the sword which protected the Biblical Garden of Eden (Genesis III, 24) may also have been an aura.
Some methods of spiritual healing are said to word by way of the aura. In Rei-Ki healing, the healer massages the aura more than the body. Sometimes one can get a feeling for the aura with no need to touch the person's body, although it is often necessary to begin by touching the various points on the body, either through clothing or directly, in order to get a feeling for the aura. Special Rei-Ki training is usually needed, to acquire this ability. Some trained Rei-Ki people can feel the aura more strongly than they can see it. (See Haloes ) (FL)
AUSCHWITZ : In Polish Oswiecim , also called Auschwitz-Birkenau. Nazi Germany's largest concentration camp included a prison, an extermination camp, and a slave-labour camp. Auschwitz has become the symbolic site of the final solution, a virtual synonym for the Holocaust. Newly arrived prisoners at the death camp were divided in a process known as Selektion . The young and the able-bodied were sent to work. Young children and their mothers and the old and infirm were sent directly to the gas chambers. Thousands of prisoners were also selected by the camp doctor, Josef MENGELE, for medical experiments. Auschwitz doctors tested methods of sterilization on the prisoners using massive doses of radiation, uterine injections, and other barbaric procedures. Experiments involving the killing of twins, upon whom autopsies were performed, were meant to provide information that would supposedly lead to the rapid expansion of the Aryan race. Subject to harsh conditionsincluding inadequate shelter and sanitationgiven minimal food, and worked to exhaustioto Auschwitz. Between 1.1 and 1.5 million people died at Auschwitz; 90 percent of them were Jews. Also among the dead were gypsies .Auschwitz was designated a UNESCO World Heritage Site in 1979. (DM)

AUSTRALIAN ABORIGINAL: The indigenous Australians believe that they have been in Australia since the Dreamtime or Creation. Although their origin is still unsubstantiated scientifically, it is hypothesized that they migrated from the South East Asian region more that 50,000 years ago when the sea was at its lowest levels and more exposed land enabled such a crossing (see GONDWANA).
Among Australias indigenous peoples many cultures exist and Aboriginal people identify as both indigenous and, whenever possible, also as a member of their language group; that is, coming from a particular place/country each identifiable by its own creation stories (see Dreamtime and Dreaming). It is estimated that at the time of invasion (Captain Phillipss landing at Botany Bay, Sydney, in 1788) there was a population of about 3 million Aboriginal peoialects - each with their own country and culture. These days, over 250 languages are spoken and tmostly English words and indigenous language structures; such as the creole, known as Kriol, spokents ensured that being identified as Aboriginal could mean further loss (see Reconciliation). Abor prevented from speaking their language or practicing their culture, and their children were denie taken away from their families to be placed in institutions, or brought up by non-Aboriginal fami by living a European lifestyle and agreeing not to associate with any Aboriginals, exceptions (re Aboriginal, for example, was awarded a certificate of citizenship in 1957 in recognition of his alcohol with his kin (the supply of alcohol was a criminal offense), was imprisoned and died soon ay the Australian electorate, granted Aboriginal and Torres Strait Islander peoples full citizenshins many of the traditional values and assumptions.

AUTISM : (Greek autos "self") a little understood rare (4 in 10,000 live births) mental disorder first named by Leo Kanner, an American psychiatrist, in 1943. The condition is characterized by extreme social withdrawal and inability to communicate verbally or emotionally with people. Impairment of social interactions may be due to an abnormal interest in fantasy engendered by delusions and hallucinations resembling schizophrenic withdrawal in adults. The onset of this pervasive developmental disorder may be in infancy or early childhood and is characterized by internally-stimulated thinking where ideas have a private meaning and abnormal ways of relating to people, objects and situations. Recent findings suggest that organic, rather than psychological, injuries in the limbic system (the brain's emotional center) might explain some elements of autistic behavior. Although far more autistic children have sub-normal levels in IQ than would be expected from the normal continuum of all levels of intelligence, a small number possess superior intelligence and/or certain skills related to their lateral thinking or highly-focused attention on aspects of interest. The best educational approach is thought to be sympathetic but formal instruction. (IP+MP)
AUTOGRAFT : (Greek autos "self" + graphion "stylus") a permanent transplantation of any tissue from one site of the body to another site in the same individual.

AUTOMATIC WEAPONS : Automatic weapons enable rapid fire by using some of the explosive energy to eject the shell and automatically reload the next bullet into the chamber. An automatic weapon fires in a continuous stream for as long as the trigger is depressed. A semi-automatic weapon fires one bullet for each click of the trigger. Mobile or mounted automatic weapons of varying sizes are also known as machine guns. The smaller sub-machine gun is designed for portability and flexibility, with lightweight frame and short barrel usually firing pistol ammunition. Many non-violent countries restrict or severely regulate civilian ownership of automatic weapons. (See SMALL ARMS, AUTONOMOUS WEAPONS) (MP)

BACTERIA: (Greek: bakterion 'small stick') Bacteria (singular: bacterium ) are small (between 1 and 10 microns) single-celled microorganisms whose genetic material is not enclosed in a special nuclear membrane. For this reason, bacteria are called procaryotes, from the Greek meaning prenucleus. Bacterial cells generally appear in one of several shapes; bacillus (rodlike), coccus (spherical or ovoid) spiral (corkscrew) or vibrios (comma-shaped) being the most common shapes. Individual bacteria may form pairs, chains, clusters, or other groupings and generally reproduce by a process called binary fission; that is, dividing into two equal daughter cells. For nutrition, most bacteria use organic chemicals, which in nature is derived from either dead or living organisms, however, some can manufacture their own food by photosynthesis and others from inorganic substances. Life on Earth as we know it would not exist if it were not for microorganisms because the microorganisms, bacteria mostly, play a key role in recycling essential nutrients when they decompose organic waste and dead plants and animals. Only a minority of all bacteria is pathogenic causing disease, while the vast majority benefit humans, other animals and plants (Greek bakterion meaning small stick) (see BIOGEOCHEMICAL CYCLE; MICROBIAL ECOLOGY; MICROORGANISMS).

BATES, WILLIAM H. (1860-1931) American ophthalmologist. In 1919 he published a book called "Better Eyesight without Glasses", which has been reprinted many times. He has been much maligned by ophthalmologists, although it is difficult to find any scientific refutation of his doctrines in the medical literature. He has also been misrepresented by commercializers who pretend to teach the "Bates Method", but then teach eye exercises unrelated to the advice given in Bates' own book. Bates believed that vision problems are not a disease of the eye but a disease of the mind. The ability to see clearly is a function of the ability to imagine clearly. And -- since tension is an obstacle to good vision -- the first step is to stop caring so much whether you see clearly or not, and just relax. This latter advice resembles an attitude cultivated by Zen archers and other Japanese martial artists, although Bates did not mention these disciplines in his book. Anecdotally, some people report high success with Bates' method and others report that they cannot understand what he is trying to say. No controlled clinical trial has been reported to date. (FL)

BEAUVOIR, SIMONE DE : (1908-1986). French writer, feminist, philosopher, leader of the post-war existentialist movement and early exponent of women's rights. In the 1940s de Beauvoir with Sartre formulated the principles of a modern existentialist philosophy that stressed the importance of personal experience in a largely meaningless world. According to these principles, people need to create their own ethical values and be responsible for their own actions. Many of her novels reflect this view - most notably 'The Blood of Others' 1948; 'All Men are Mortal' 1955; 'The Woman Destroyed' 1968. A long commitment to improving the status of women gave rise in 1949 to her immeasurably popular and controversial book 'The Second Sex' . ' The Second Sex' traces women's oppression by male-dominated society and effectively argues that women's inferior social position does not reflect biology but systematic political subjugation. Simone de Beauvoir's 'ovarian' work had a profound influence on the Women's Liberation Movement of the 1960s and influenced later feminist writers. (See DWORKIN, ANDREA, GREER, GERMAINE). (IP)

BENTHAM, JEREMY: (1748-1832) One of the founders of the Utilitarian movement in philosophical ethics. He tried to put ethics on a scientific foundation by interpreting good and pleasure, and evil as pain, and by proposing as calculus of pleasures and pains which would give a scientific measure of the rightness or wrongness of the action. Although a seminal thinker, his follower, John Stuart Mill (q.v.) is probably better known today. (FL)
BENTHOS: 1. Benthos is the bed or bottom of a body of water, including the layers of mud, silt or sand. 2. Benthos (or benthon; benthic organisms) are the animals and plants which live on the seabed or lake bottom. (See ESTUARY, SEAGRASS) (MP)

BERKELEY, GEORGE : ( 1685-1753) Irish Bishop and philosopher. Berkeley, California, is named for him because of his prophetic poem about the course of British Empire moving westward.. He argued that matter doesn't exist. What we call material objects are really collections of sense perceptions -- colours, sounds, smells, tastes and tactile sensations -- which he called "ideas", and which he believed exist only in the mind. He was therefore the father both of radical Empiricism and of the Logical Positivist school in philosophy of science. He believed that we get our sense experiences directly from God, who needs no such intermediaries as material objects, and who gives us experiences not to teach us about a material world but to teach us moral lessons. (FL)

The Gita is one of the principal scriptures of Hinduism, the oldest of the great, formal religions of the world. It has a deep philosophical structure projecting the essence of the Vedas, the cornerstones of Hindu orthodox tradition, interlaced in the dramatic background of the ancient great battle, the Mahabharata. While the latter is composed by the sage-author Vedvyasa, the origin of the Gita is attributed to Krishna, a major player in the Mahabharata, and believed to be one of the few great avatars (incarnations) of the Supreme Lord, now regarded as Vishnu, the Creator among the Hindu trinity of Brhama, Vishnu and Mahesh.
On the battlefield of Kurukshetra, where the Great War of Mahabharata was about to commence, Arjuna, the great archer Prince of the Pandav dynasty facing the armies of the related clan of Kauravas, was overwhelmed by the piquancy of having to do battle unto death with his own kin. He voiced his feelings of utter confusion and dejection by seeking to lay down arms rather than destroy his own flesh and blood for the sake of worldly wealth in the form of the Kingdom of Hastinapur for his Pandava clan. Krishna, the renowned warrior strategist with manifest divine origins and nature, had sworn not to take to arms or sides with either of the two feuding clans since both were his friends and relatives. He had therefore offered to both either his powerful army, or only himself, unarmed. The Kauravas had chosen his army, and the Pandavas chose him alone. Krishna offered to be the charioteer of Arjuna, his friend and the prime archer among the Pandava brothers. Thus, seeing Arjuna falter on the eve of the great battle, Krishna gave him the message of Gita, which has since become not only Hinduism's but one of Humanity's universal theological philosophy.
Krishna's message, or the teaching of the Gita , in the briefest nutshell, was based on the philosophy of Karma, or Action. According to the Gita, Man was enjoined to do his dutiful and right (moral) Karma, without seeking fruit in the form of rewards, but ascribing, or offering the latter, as indeed the Karma itself, to the Lord. Krishna also expounded the doctrine of Re-birth in which the soul passes through several incarnations. Thus, earthly relations such as father, mother, brother, uncle, wife, son etc are all essentially illusory and impermanent. Only the corporeal body dies. The soul does not. The soul is untouched by pain, joy or death. It remains unscathed , and passes through cycles of birth and rebirth till its good Karmas release it from these sagas of suffering and unite it with the Supreme. Thus, opined Krishna, the father of this birth may be the son in the next. Such relations are transient, as is Life. Only the soul is permanent, and its journey through time is governed by Karmas performed through the various Lives. Only Karma which is performed in the line of duty, is moral, and whose rewards are not sought but even if accruing are offered to the Lord is the one which is the noblest. After hearing the exposition of this new and great philosophy of the Gita, Arjuna took up arms and and the battle of Mahabharata was fought and won victory for the morally rightful Pandavas.
The Gita has also been called the Song Divine. It is written in Sanskrit in the form of shlokas, or poetic stanzas, and comprised of 18 chapters. It has been translated in all major languages of the world and has been the subject of inumerable commentaries. Many of its principal cornerstones, eg the idea of Karma, rebirth, the immutability of the soul etc have entered not only the parlance, but the spirit of the modern universal human psyche. (RNS)
BHOPAL : Bhopal is a city in the State of Madya Pradesh in central India. It is the site of an industrial tragedy, which killed about 2000 people and injured many others. In 1985, Union Carbide chemical industry met with an accident, which involved the leak of the poisonous gas methyl isocyanate (MIC). The victims who inhaled MIC were subjected to cyanide poisoning with necrosis of the cells in the respiratory tract. Many legal and ethical issues were raised, some of which were not settled. (JA)

BICYCLE TRANSPORT: Safe and extensive bicycle transport networks are an essential component of a healthy city. Cycling is an addition rather than an alternative to car commuting. Advantages in cities include less traffic congestion, parking space and air pollution, and advantages to cyclists are equitability, convenience, exercise and enjoyment. In some cities there is a monthly "Critical Mass"; a cyclist demonstration and congregation on central city arteries to highlight the demand for cycle-ways and affirm cyclist road rights. Many Asian and other poorer countries have high proportions of cyclists on the roads, but models for bicycle-friendly cities may be found in certain European countries such as Holland, where safe cycle-ways and a culture of respect for cyclists are standard. (See SUSTAINABLE CITIES) (MP)
BIG BANG: Astrophysical theory about the origin of our universe. The Big Bang was the beginning of both time and space, a giant explosion around 14 billion years ago which expanded rapidly, cooled and coalesced into the universe of today. Some predictions from the theory have since had corresponding data from the distant universe, and the theory is believed by much of the science community. The total mass of the universe will have a bearing on whether the universe will continue expanding forever (the heat death of the universe) or contract back again due to gravity (the Big Crunch).

BIOCONVERSION : BIOS = life, It is a method in biotechnology. Transformation of chemical products into its raw materials or into another form by biological organisms like converting hydrocarbons to alcohols also called biological transformation or microbial transformation (since microbes are used). Extensively used in organic chemistry for carrying out complex synthesis. e.g. fermentation of sugar into alcohol by microbes. The soil bacterium Pseudomonas can break down organic compounds and has been used in industrial applications. Organic waste can be converted to the biogas methane when fermented under anaerobic conditions. Methane can be used to produce light and in cooking. (JA)
see Biological diversity - indicates the total number of living species found in the biosphere including variations found in form and function in the entire biological systems. Three types of biodiversity- genetic (molecular), biological (organismal) and habitat (ecological), the word first appeared in biological literature in 1986, given preeminent importance during the Convention on Biodiversity held in Rio in 1992. Biodiversity is an index of the biological wealth of this planet (see CONVENTION OF BIOLOGICAL DIVERSITY) (JA+GK+IP)
BIODIVERSITY HOTSPOT : A region of very high endemism where threats to habitat integrity or of extinction are also high. As human activities are drastically accelerating extinction worldwide and only limited resources are available to conserve many endangered organisms, this concept was proposed to focus effort and funding on areas where there might be the best possible conservation results. Conservation International (http://www.conservation.org/xp/CIWEB/home) leads efforts to mobilize international public and private resources to support conservation of biodiversity hotspots with involvement of local communities. (RW)

(IP)
Term coined by Darryl Macer in 1994.
A mature society is one which has developed some of the social and behavioural tools to balance bioethical principles, and apply them to new situation
s raised by technology. We could call the bioethical maturity of a society the ability to balance the benefits
of applications of biological or medical technology. It is also reflected in the extent to which the public views are incorporated into policy-making while respecting the duties of society to ensure individual's informed choice. Awareness of concerns and risks should be maintained, and debated, for it may lessen the possibility of misuse of these technologies. Other important ideals of bioethics such as autonomy
need to be protected and included in the benefit/risk balancing which is important for the ethical application of biotechnology
in medicine. Concern about technology should be valued as discretion that is basic to increasing the bioethical maturity of a society, rather than being fear
ed as a barrier to the implementation of new technology. (DM)
BIOETHICS 1. the study of life ethics. A word coined in the later part of the 20 th century to describe the various rights and wrongs of new scientific and technological procedures and discoveries (in particular in response to human experimentation during World War II) which were seen to bear a direct and significant impact upon humane survival". 2. Rules of conduct in scientific research and involves many disciplines and skills such as law, philosophy, theology medicine, science and technological research [derived from Greek bio - life and ethicos moral]. 3. Love of Life. (see BIOSCIENCE ETHICS). (IP+DM)
BIOETHICS COMMITTEES: Groups of people set up to adjudicate about bioethical matters. In an increasing number of countries such committees are established in law and are charged with certain legal responsibilities, typically about the conduct of research or clinical practice at either local or national level. (MR)
BIOETHICS INFORMATION DIRECTORIES: Bioethics is a subject which covers an encompassing range of issues and information. Organizations and internet directories which increase the accessibility and dissemination of bioethics information include Eubios Ethics Institute, Kennedy Institute of Ethics, Bioethicsline, Bioethics Net, International Association of Bioethics, International Society for Environmental Ethics, and Institute for Global Ethics. (See MEDICAL INFORMATION DIRECTORIES, ENVIRONMENTAL INFORMATION DIRECTORIES) (MP)
BIOGAS : is a non conventional energy, methane as a natural gas is an example. When organic waste is fermented using methanogenic bacteria, methane is produced also called the marsh gas. Biogas is an alternate source of energy, can be used in domestic applications such as lighting a house. (JA)
Refers to the reciprocal interactions between living organisms and their elemental bio-cycles. Earth is essentially a closed system with respect to carbon, hydrogen, oxygen, nitrogen, phosphorus and sulfur the elements organisms need in large quantities; thus, these elements cycle from the environment through organisms back to the environment in sustainable harmony. There are two major types of biogeochemical cycles - gaseous and sedimentary, where each element has its distinct cycle with the specifics depending on its physical and chemical properties and how it is utilized by organisms (see CARBON CYCLE; NITROGEN CYCLE; HYDROLOGICAL CYCLE). (JA+IP)
BIOGEOCHEMISTRY : The study of fluxes and transformations of the materials that constitute the Earth, including the Earth's interior, surface, oceans, and atmosphere. (RW)
BIOGEOCOENOSIS: A seemless partnership between living organisms and their physical environment. Frequently used in Russian literature, equivalent to the word "ecosystem". (JA)
BIOGEOGRAPHY: The branch of biology which studies the geographical range and distribution of animals and plants across the earth. Of particular importance to ecological sustainability is the distribution and abundance of keystone, endangered and exotic pest species. (MP)
BIOHAZARD: A health hazard from a biological organism or substance. (See BIOSAFETY). (DM)
BIOINFORMATICS: The acquisition, management, analysis, storing and processing of biological information; such as, gene sequences, genomics, biological structures, pharmaceutical chemicals, taxonomy, biodiversity and environment. Biomolecules such as DNA and proteins have large amounts of information of biological interest. DNA is called the blue print of life and proteins are the building blocks of life. Developed out of a combination of computer science, information technology and genetics to determine and analyze genetic/biological information, and these technologies can be now used as a scientific basis on which ethical decisions can be made. Origin - the first bioinformatic databases were constructed a few years after the first protein sequences began to become available. The first protein sequence reported was that of bovine insulin in 1956, consisting of 51 residues. Nearly a decade later, the first nuclei acid sequence was reported, that of yeast alanine tRNA with 77 bases. Soon thereafter Dayhoff gathered all the available sequence data to create the first bioinformatic database . Organizations in biomolecular databases have two goals: (i) to get valuable and practical information out of these databases (ii) to integrate information from diverse sources. DNA databases are stored in GenBank Company in USA and also in the European Molecular Biology Laboratory in Germany. Similar protein sequence databases are also available. (See INFORMATICS, GENBANK) (IP, JA)

BIOLOGICAL: Any event/processes relating to life/organisms. (JA)
BIOLOGICAL CONTROL is a method of controlling pest species by introducing one of their natural predators or otherwise interfering with their life cycle; for example, the Mediterranean fruit fly has been successfully controlled by the method known as "sterile male technique" where unproductive adult flies are released into their habitat after the pupae were sterilized by exposure to gamma radiation. This method has distinct advantages over the use of toxic, non-biodegradable chemicals. (IP)
BIOLOGICAL DETERMINISM theory that human action or behavior (aggression, sexual orientation, sex roles, intelligence and so on) are not free but set by genetics. The theory always becomes popular at times of political austerity where whole populations are encouraged to believe that their social prejudices are scientifically based (see DETERMINISM). (IP)
BIOLOGICAL DIVERSITY See BIODIVERSITY.
BIOLOGICAL SCALES: Fields of biology and units of biodiversity organized by increasing scale and complexity are as follows: carbon chemistry leads into biochemistry, genetics, molecular biology, cellular biology, physiology, organism biology, behavioral studies, community biology, ecology, environmental biology, human ecology, evolutionary biology, Gaia hypothesis, artificial life, psychology, consciousness and further into biological philosophy and bioethics. (See BIOLOGY, BIODIVERSITY, BIOETHICS). (MP)
BIOLOGICAL SYSTEMS: see BIOSYSTEMS.
BIOLOGICAL TISSUES BANKS: BLOOD BANK, DNA BANK, CELL BANK, ORGAN DONOR BANK. Refers to a collection of samples gathered from free donors, whose purpose is to serve as tissue (blood) or organ donor center to save sick peoples" lives (blood transfusions or organ transplantation). DNA and cell banks are meant to provide samples for research purposes, either in genetic, physiology, biochemistry or other experimental protocols. Neither of these tissue banks have commercial interests. In the case some money is charged, it is to compensate the costs of maintaining, culturing and dispatching the samples. (See also REPOSITORY.) (GK)
BIOLOGICAL WARFARE: Waging war by the deployment of biological weapons; that is, the deliberate release of natural or genetically engineered disease causing organisms, or their products, into enemy territory. The threat of biological warfare has not decreased since the signing of the 1972 worldwide treaty on Biological and Toxic Weapons which in theory prohibits their development and deployment. On the contrary, the danger of institutionalized terrorism has become more real with the alleged stockpiling of many agent of germ warfare (see BIOWEAPON, INSTITUTION OF WAR & VIRTUAL WARFARE, ETHNIC CLEANSING). (IP+GK)
BIOLOGY: Bios (life), logy (study). The science of life. Includes the study of zoology and botany. The term appeared in a book title during 1802 by a German physican , Gottfried Reinhold Treviranus, the title of the book being, "Biologie oder Philosophie der lebenden Natur fur Naturforscher und Aerzte (Biology, or philosophy of the living Nature for Scientists and Physicians" Source - firstname.lastname@example.org (JA)
BIOLUMINESCENCE AND BIOELECTRICITY the production of light or electric discharges by living organisms. The mechanism has evolved independently in many kinds of organisms from bacteria to vertebrates; for example fireflies who produce flashes of light used to attract mates, the electric eel who can generate up to 550 volts which it uses for offense and defense, fishes who use electric organs and electroreceptors for navigation purposes and a variety of deep-sea creatures who are luminescent by means of either light-producing body cells or by specialized organs containing luminous bacteria. Now we can also include human engineered chimeras, like the tobacco plant which produces a dazzling light when watered with an appropriate substrate due to the inclusion into its genome the luminescent firefly gene. (IP)
BIOMAGNIFICATION : The increase in toxicity of chemically stable synthetic human-made compounds which resist the natural detoxifying processes of excretion and decay, so the poison accumulates exponentially in the animal body as it progress up the food chain (see Food Web) and, through the process of magnification, the concentrations of any single pollutant can be millions of times greater in the body of a top predator (carnivores like the eagle, tiger or human) compared with the surrounding environment. For example, the biomagnification of PCBs in fish can be concentrated to reach an accumulation factor exceeding 250,000 times that in the water (see FOOD WEB, POLYCHLORINATED BIPHENYLS, ENDOCRINE DISRUPTERS & DDT). (IP)
BIOMASS: The total biological mass, quantity of living matter, or dry weight of a particular species, within a habitat or geographical area. Since species differ in size, the use of the mass rather than the number of organisms per unit of area helps to indicate the importance of a population in relation to productivity and the flow of energy and nutrients through an ecosystem. The global biomass consists of all of the organisms in the world. (See BIODIVERSITY). (MP)
BIOMASS ENERGY: Biomass energy is fuel stored in organic matter such as plants or animals and their waste products. Much of the population in developing nations rely on biomass for fuel, especially from wood. Although a renewable resource, improperly managed use of fuelwood is having adverse impacts on habitats and biodiversity. The burning of dung indoors for heating or cooking has also been implicated in respiratory health problems. (See BIOMASS, RENEWABLE ENERGY) (MP)
BIOME: (Greek: bio "life" + oma "tumor" or "mass"). A major ecological community or category of habitat, and having a characteristic ecology, climate or geographical region. (MP)
BIOMEDICAL ETHICS: Domain of ethics (moral philosophy) concerned with such medical matters as ABORTION (q.v.), CLINICAL TRIALS (q.v.) and EUTHANASIA (q.v.). (MR)
BIOMEDICAL RESEARCH: Biomedical research is usually thought of as highly scientific laboratory or clinical research. But vast numbers of the world's population, maybe the majority, have no access to medicine at all. They have little chance to benefit from the results of high-tech medical research. So research into methods to teach healthy behavior to medically deprived populations should be thought of as a central part of biomedical research. This research would include strategies for encouraging avoidance of sexually transmitted diseases (as through condom use), healthy and sanitary childbirth, simple methods of environmental health, like digging a pit for nightsoil so that children won't wander in it barefoot and become invested with parasites, simple nutritional advice, etc. Researchers should seriously study whether low-tech biomedical research of this sort might save many more lives than the high-tech sort. (FL)
BIOMEDICAL WASTE : Atretions/secretions, contaminated with blood. (JA)
BIOMETRICS: 1. Also known as biometry, biometrics is the application of statistics to biological data. 2. The use of distinctive biological characteristics for the recognition and positive identification of an individual. The most familiar biometric tag is the fingerprint, but the technology is fast advancing examples include iris pattern scanning, electronic voice verification, DNA fingerprinting and face recognition in security cameras.

BIOPHYSICS: The science of the application of the laws of physics to life processes. (See PHYSICS; BIOENGINEERING; BIOTECH; BIOTECHNOLOGY). (IP)
1. The use of nature or traditional knowledge and/or medicines for modern use without consent and/or acknowledgment of their origins 2. theft of biological knowledge for profit. Origin - the first patent was granted to General Electric Company in 1971 for what the "inventor" - Anand Mohan Chakravarty - described as "
I simply shuffled genes, changing bacteria that already existed
." This stimulated a rush by US corporations to understand, and ultimately, to patent and claim ownership of existent and modified life forms. From this behavior the term "biopiracy" was coined (see web site at http://www.cqs.com/biopiracy.htm). (IP)
BIOPROSPECTING : Investigative collection of living organisms with the aim of uncovering potentially useful applications, for example biomimetic design features, unique genetic information, food and crop varieties, indigenous medicines, and especially with reference to the potential presence of pharmaceutically-active alkaloids. Conservationists and developers today find agreement over the value of biodiversity protection, at least on practical if not ideological grounds. Less than 1 or 2% of Earth's organisms have been examined - the investigation and conservation of global biodiversity remaining one of the last great unexplored and undervalued realms of scientific discovery.

BIOPSY: The surgical removal of a cell or sample of tissue for diagnostic purposes. (DM)
BIOREGION: An integrated and continuous natural area which contains an interconnected biophysical system, for example a river catchment, mountain range or other discrete ecosystem. (See BIOREGIONALISM) (MP)
BIOREGIONALISM: The defining and management of regions according to their biophysical and ecological characteristics, without restriction by political borders or other arbitrary human boundaries. This recognizes the integrity and continuity of large biological systems such as habitats and ecosystems, and is the appropriate large-scale unit for integrated management and monitoring of environmental impacts and change. (See BIOREGION, INTEGRATED MANAGEMENT) (MP)
BIOREMEDIATION: Cleaning the environment of pollution and waste materials of human origin using the ability of microorganisms to break down complex organic and inorganic compounds. The organic decontamination or resuscitation of ex-industrial sites and other desecrated lands can be achieved using biologically active plants, fungi and bacteria. These destroy or degrade pollutant chemicals into their basic components and remediate the soil creating a viable ecology or usable land quality. For example, keratinophilic fungi can break down the keratins of hair, nails and feathers efficiently into basic biochemicals which can be reused. Bioremediation technologies include composting, land-farming organisms on site, bioreactor organisms cultured offsite, soil-bank air and water networks, ecological and biochemical techniques. Research includes enzymic incorporation of pesticide residues, and desalination of soils by plant biomass. Alternative chemical and physical remediation processes may also serve to transfer rather than to degrade many pollutants.

Implementation of international safeguards, Controlling agency like Food and Drug Administrative Office (US). (JA)
BIOSCIENCE ETHICS: Acts as the interface between science and bioethics - science is descriptive and ethically neutral as it deals with facts requiring verification, whereas ethics is prescriptive dealing with what ought to be and depends on intellectual justification; however, if the bioethical discussion is to be relevant to our knowledge-based lives, there is the expectation of high biological standards in agreement with modern scientific insights. Bioscience ethics resides in between scientific endeavor and its application into acceptable forms of bioethical consensus with its major elements being increased understanding of biological systems, responsible use of technology and curtailment of ethnocentric debates more in tune with new scientific insights. Irina Pollard and Steven Gilbert first used the term in 1997 (see Bioethics , SCIENTIFIC METHOD). (IP)
BIOSPHERE: It is a combination of two words - bios (life) and sphere (globe), meaning a globe that can sustain life, e.g. Earth. Largest self-sustaining and self-maintaining biological system. Biosphere = Ecosphere. refers to the regions of the Earths atmosphere and crust occupied by living matter (see Cryosphere, Hydrosphere & Exosphere) [Greek bios = life + sphaira = globe] (JA+IP)
BIOSPHERE 2 PROJECT: Biosphere 1 is Gaia, or the Earth. The Biosphere 2 Project was a closed-environment experiment in which 8 humans were enclosed for two years (1991-93) in a large artificial habitat in Arizona. The glass domes of Biosphere 2 contained 204,000 cubic meters including a mini-sea, mangroves, rainforest, desert and farm. Unexpected difficulties arose in the maintenance of the system over the two years, for example most vertebrate and insect species went extinct, including all plant pollinators. Most problematic was the biogeochemical regulation of water quality and the atmosphere, with oxygen in the end having to be added from the outside. Such mixed success maintaining a self-sufficient colony can only further impress the need for preservation of the intricate ecological life-support systems already provided by the Earth, but taken for granted. (See BIOSPHERE, ARTIFICIAL HABITAT) (MP)

BIOTA : The combined living organisms of a given ecological habitat, biome or geographical region, comprising all of the plants, animals and microorganisms. The collection of all organisms living in a place. (See BIODIVERSITY, BIOMASS) (MP, RW)
BIOTECH: The shortened form of "biotechnology" which first appeared in the 1970s when it became possible to manipulate the genetic make-up of living organisms; for example, biotech companies can create plants and animals with new characteristics such as resistance to disease where the biotechnician is a person working in a biotech laboratory. Since the 1970s, the creation of modified life-forms have generated heated ethical and environmental controversy (see BIOTECHNOLOGY AND GENETIC ENGINEERING). (IP)
BIOTECHNOLOGY: The use or development of techniques using organisms (or parts of organisms) to provide or improve goods or services. It is the application of biological knowledge for the purpose of solving practical problems in healthcare, agriculture, veterinary science and related fields (see BIOTECH AND GENETIC ENGINEERING). (IP, DM, DR)
BIOTIC COMMUNITY : The community consisting of all of earths living organisms. The proposal for an extension of ethics to cover all the species of the living systems emerged in the 20 th century, particularly by means of Aldo Leopolds A Sand County Almanac and Sketches Here and There (1949). (CP)
: A weaponry must have the killing power and is easy to manufacture and handle; to weaponise biological organisms as agents of mass destruction of human beings. Between a 100 Kg bomb and 100 Kg bacteria, the kill is greater in the later. It can kill from one to four million people depending upon the spread of bacterial. See Anthrax, smallpox. (JA)
BIPOLAR (MANIC) DEPRESSION: a spectrum disorder where the sufferer can be in varying degrees manic (elation/excitement) or even-tempered, depressed (melancholia) or normal, or alternating between mania and depression. The condition can be severe, intermittent or chronic and can be primary or secondary. A primary depression is one where the particular mood disorder is the dominant problem, while in a secondary depression a number of psychological, physiological and/or social variables, for example, schizophrenia, drug abuse (alcoholism, marijuana, amphetamines, cocaine), extreme nutritional deficiencies and physical illness, may produce the symptoms. On the whole, bipolar patients are a much more homogeneous group compared to unipolar depressives as they experience, in varying degrees, alternating cycles of mania and depression. They are also more responsive to treatment with lithium salts than are those with recurrent attacks of depression only. If severe manic episodes escalate, the patient may lose contact with reality, hallucinate and, if coupled with paranoia, become openly psychotic (see DEPRESSION; UNIPOLAR DEPRESSION; BRAIN NEUROTRANSMITTERS; LITHIUM; SEROTONIN RE-UPTAKE INHIBITORS). (IP)
BIRDS : Homeothermic (warm-blooded), feathered, egg-laying vertebrates of the class Aves. The forelimb of birds is in the form of a wing, though not all birds fly. According to the World Conservation Union (IUCN) Red Book data from year 2000, about 12% of birds face a serious risk of extinction during the next 100 years. (RW)
BIRTH CONTROL: The prevention of birth. Birth control has been practiced by different contraceptive methods in almost all cultures and epochs. It has not been an exclusivity of females, since males have used different means to kill sperm cells before intercourse. Birth control policies in Latin America have been introduced with great effort since the sixties, first by private ONGs, then by national health services, but in many of these countries, the Catholic church has tirelessly been opposed to any method different from the rhythm method (Ogyno). As a result of educational campaigns and higher schooling, middle to upper classes in these countries have gained control over their reproductive choices, reducing the overall birthrate, but lower classes still have high numbers of children and do not use contraceptive methods.

BIRTH DEFECTS : hereditary birth defects are transmitted by the parents genes; however, many birth defects are the result of e the greater uncertainty about their predictability. (See TERATOLOGY; CONGENITAL MALFORMATION). (IP)
BIRTH RATE: Quantification of the potential rate of increase of a population due to the production (birth) of new individuals. Normally expressed as number of young produced per adult female per unit time. (MR)
BIT: (Binary + Digit) A bit is the smallest unit of information in mathematics or computer terminology, representing the presence or absence of a single feature (1 or 0; on or off). Eight bits comprise one byte. (See BYTE, QUBIT) (MP)
BLACK AND WHITE THINKING: See CONTINUUM, ADAPTIVE THINKING.
BLACK HOLE: Coined in 1969 by John Wheeler and further theorized by Stephen Hawking among others, a black hole is a point in the universe of immense gravity, often created by the collapse upon itself of a giant star some twenty times the size of our Sun or larger. A black hole is so dense that matter or light cannot escape once past the event horizon. The centre is postulated to be an infinitely dense point known as a singularity. Contrary alaxies. (See WORMHOLE, SINGULARITY, EVENT HORIZON, BIG BANG, PARALLEL UNIVERSES THEORY) (MP)
A hollow ball of cells, filled with fluid, that forms about four days after fertilization from the zygote, and prior to the beginning of the process of implantation. The embryo develops from a small cluster of cells in the centre of the sphere, and the outer wall of the sphere becomes the placenta. (DM)
BLASTOMERES: The daughter cells that derive from the first and subsequent cleavages of the zygote. (DM)
BLIND EXPERIMENT: See DOUBLE BLIND EXPERIMENT

BOARD : An authority with office bearers and expert members possessing qualifications, knowledge and experience of scientific engineering or management aspects of a given subject for example, Pollution. The Board accordingly is the Pollution Control Board, which is empowered to give directions requiring control measures. (JA)
BOAT PEOPLE: A term often used to mean illegal immigrants arriving by boat, often in an attempt to escape brutality or impoverishment. In sympathy, perhaps it should be remembered that Europeans in Australasia and North America, and Chinese and Korean forefathers of Japanese in Japan, were originally boat people themselves. (MP, DM)
BODHISATTVA : Buddha-in-the-making, literally an "enlightenment being"- to keep free all beings from the coils of suffering. (JA)
BONE MARROW : soft, spongy tissue found in the center of large bones that is essential in the manufacture and maturation of blood cells (white cells, red cells and platelets). It is sensitive to the effects of radiation, anticancer drugs and toxic agents (e.g. benzene). Damage to the bone marrow can cause leukemia or suppressed immune system. (See CANCER; IMMUNE SYSTEM; IMMUNITY). (SG2)
BOOK OF ENOCH:
The name of several unrelated books of the Apocrypha. Each of these books is ascribed to the Biblical figure Enoch, who has long been associated with visions, due to the cryptic note in Genesis 5,24 that he was no longer to be found because God "took him". No direct mention is made of Enoch's death, and so, a tradition developed that he ascended alive to Heaven. Each of the books called "Enoch" describes a collection of heavenly visions. The Ethiopian Book of Enoch in particular supplies much information on angelology, and supplies the names of a large number of angels. (AG)
BOOK OF MORMON: A central scripture of the Mormons. This book is actually a collection of many books, and serves as a "Third Testament" for the Mormons, in addition to the Old Testament and the New Testament. The Book of Mormon chronicles historical events and figures important to Mormon history starting from the 2nd Temple period in Judea, and continuing in North America of ancient times. According to Mormon tradition, this history was written on golden plates in a form of the Egyptian language and was hidden in ancient times in North America. In modern times, they were rediscovered by Joseph Smith, and with the assistance of the angel Moroni, Joseph Smith translated these records on the golden plates from Egyptian to English. The standard Book of Mormon is now printed in English. Two other books important to Mormons (although not as central as the Book of Mormon) are "Pearl of Great Price", and "Doctrines and Covenants". (AG)
BOOK OF THE DEAD: Tibetan Book of the Dead (In Tibetan, "Bardo thos grol chen mo", meaning "The Great Book of Natural Liberation Through Understanding in the Between". The popular title of the book in English, however, is "Book of the Dead"). A Tibetan Buddhist text written by Padma Sambhava in the 8th/9th century which explains the stages through which a person goes during the process of dying, and the process through which the person's soul is reborn into another body to begin a new life. The book is useful both to an individual who is dying, and to relatives and friends, because it explains both what process the dying person goes through and the prayers which are helpful in assisting the individual to be reborn in the next life. The book contains a day by day description of the stages the individual's soul goes through, and the beings it encounters leading up to rebirth. (AG)
BOOK OF THE DEAD: Egyptian Book of the Dead A collection of magical texts which were written on papyrus by the ancient Egyptians and placed upon their dead in order to assist the deceased with their journey through the netherworld, and to help them deal with the dangers of this journey, and ultimately help them attain the afterlife. The text was divided into spells, and was accompanied by pictures and illustrations which further explained the various aspects of the netherworld. The earliest such collection of papyri from the middle of the 15th century bce, but the traditions contained within them are a great deal more ancient. (AG)
BOOLEAN LOGIC: Named for the English mathematician George Boole, Boolean Logic uses the logical relationships AND, OR and NOT, useful for symbolic representation in Boolean algebra and computer programming. (See GAME THEORY, MODEL) (MP)
BOOMERANG: Australian Aboriginal returning and non-returning flat hardwood object used for hunting or ceremonial purposes. Nowadays the most popular model is shaped such that the projectile returns to its thrower. In areas of Arnhem Land in the Northern Territory it was also used as a musical instrument as well as a hunting tool. Term is also colloquially used to indicate 'the return to' or 'recoil upon' the originator of an idea, gift, promise etc like " a boomerang decision", " a boomerang cheque" and of particular importance a dishonored political promises made to the Aboriginal people like " boomeranged promises" (see CORROBOREE; RECONCILIATION).

BOREAL FOREST: See CONIFEROUS FOREST.
is an example of ex situ conservation where endangered plants are grown under human care and protection. There are about 1,500 botanical gardens world wide, mostly found in industrialized countries. About 230 botanical gardens are found in topical developing countries, which are rich in plant diversity. (JA)
BOTANY: (Greek: botani "plant") The branch of biological science dealing with plant life, for example the classification, structure or ecology of plants, or the flora characteristics of a particular time or region. (MP)
BOTULISM: (Latin: botulus "sausage"). An often fatal form of food poisoning caused by the endotoxin produced by the anaerobic bacterium Clostridium botulinum . The toxin is ingested in contaminated food from improper sterilization during canning or preservation, but the live bacteria need not necessarily be present once the toxin has been released. Unlike other forms of food poisoning, symptoms occur from 18 hours up to one week post-ingestion, and include lassitude, fatigue, muscle weakness and visual disturbances. Nausea and vomiting occurs in less than 50% of cases. Two thirds of cases are fatal, usually as a result of delayed diagnosis and treatment. (See ENDOTOXIN, FOOD SAFETY) (MP & IP)
BOTULINUM TOXIN : A bacterial toxin of Clostridium botulinum , One gram of crystalline toxin can kill about one million people. (JA)
BOVINE SPONGIFORM ENCEPHALOPATHY (BSE) a fatal degenerative Prion brain disease of cattle characterized by clumsy, jerky movements, loss of balance and apprehensive behavior. The disease was first observed in cattle by veterinarians in 1983 with its outbreak in England being associated with other spongiform encephalopathies such as scrapie in sheep, from which it is hypothesized it crossed species through scrapie-infected bone and meal supplemented cattle feed. The subsequent outbreak of a new variant of Creuzfeldt-Jabob disease in humans during the 1980s was blamed on the consumption of BSE-infected beef, though there is no conclusive scientific proof of this transmission; however there is a major concern as bovine albumin has been routinely used in Assisted Reproductive Technology programs, organ culture media and blood products (see PRIONS & CREUTZFELDT-JAKOB DISEASE). (IP)
BOVINE SOMATOTROPIN (bST) : Somatotropin is a growth hormone found in all mammals, and in lactating cows (bovine) it increases milk production. In the early 1990s, bacterium E. Coli was genetically engineered to produce bST, which made its use economically practical in dairy farming. Bovine Somatotrophin hormone also know as Bovine Growth Hormone. However, the use of bST to increase commercial milk production continues to be controversial. The genetically engineered (GE) hormone (rBST) was manufactured by a multinational company, the Monsanto as an agricultural product to improve the growth rate and protein and was approved for use in USA in 1993. A few side effects in animal health concerns have been noticed in the treated cows which include increased risk of udder infection (mastitis) , lameness and a reduction in life span. (See GENETIC ENGINEERING). (SG2, JA)
: The structure of the nervous system that provides the highest level of integration, control and regulation. It weighs about 1.5 kg in the adult (only about 2.5% of body weight) but receives 15% of the blood supply and 25% of the oxygen consumed by the body. The cells in the brain are far more individualized in structure and function than cells in any other part of the body. The brain can be divided up into a) cerebrum comprised of four lobes (frontal, temporal, parietal and occipital) where each lobe has special functions; b) cerebellum which helps the body to maintain balance by integrating several kinds of information such as vision, inner ear and impulses caused by the effect of gravity. Besides equilibrium the cerebellum affects muscular coordination and the autonomic execution of fine movements; c) the brain stem that connects the higher brain centers with the spinal cord and is the seat of the basic involuntary functions in the brain stem. The brain stem is divided up into several sections - the hypothalamus which regulates the hormones through the body by its secretions to the pituitary gland (growth, puberty, metabolism and reproduction) and the lowest part being the medulla whose cells control many autonomic and involuntary functions such as heart beat, breathing, intestinal activity and so on. (See BRAIN NEUROTRANSMITTERS). (IP)
BRAIN DEATH : Defined as the entire, permanent, irreversible cessation of functions of the brain stem that is synonymous with brain-stem death, since the centers for the control of such essential body functions as consciousness, respiration and blood pressure are situated within the brain stem". It is significant that guidelines on live donor transplantation, Cadaver donor transplantation and the on recipients of transplantation are being considered (JA..+FL,IP)
BRAIN DEATH, BRAIN-STEM DEATH: After the first heart transplant in 1968, people began to raise questions about whether a heart can be transplanted without murdering the donor. For the procedure can be begun only if the heart has not died a natural death, ie only if it is still beating. But if the heart is beating then the patient seemed -- by traditional standards -- still to be alive. The problem was solved in many countries by defining "death' as the death of the brain. "Brain death" was then defined as brain-stem death, and clinical criteria were developed for determining brain-stem death.
Brain death is to be distinguished from other syndromes, like Persistant Vegetative State, Permanent Vegetative State, Locked-in Syndrome, Advanced Dementia, etc, where one may be unresponsive to stimuli while the brain is nonetheless alive. Indeed in the Persistant Vegetative State there are discernible periods of sleep and wakefulness, and there has been some success in restoring PVS patient to various degrees of conscious function, as has been reported in a number of papers by Keith Andrews in London.
In a classic paper, Robert Truog and James Fackler (Critical Care Medicine, (1992) 20: 1705-1712) brought considerable clinical evidence to show that patients who have satisfied then-current criteria for Brain Death retained, nonetheless, brain function in the forms of hypothalamic endocrine function; cerebral electric activity; some environmental responsiveness with clear hemodynamic response to surgical incision at the time of organ removal; and spinal cord function in the form of spinal reflexes.
In the light of these data, one might easily conclude that we are harvesting organs from people who are really alive. Such a conclusion can lead to either of two quite contradictory courses of action. On the one hand it can be concluded that if we are already taking organs from live people, then we may as well find even more fruitful sources of organs and take them from patients in the Persistant Vegetative State (a position close to that advocated in a later article by Truog: Is it time to abandon brain death? HCR (1997) 27:29-37), or even from severely demented or other seriously mentally ill patients. But on the other hand one might conclude exactly the opposite, ie that if heart and other major organ transplantation requires taking organs from live people, then this is murder and such transplantations ought to be stopped.
The dilemma is reflected in debates within ancient spiritual cultures, such as Israel and Japan. Since 1997, Japan has had a law allowing taking hearts from brain-dead patients, for transplantation. But there both lay and scientifically educated Japanese have been reluctant to donate, perhaps because of deep-rooted beliefs about the importance of heartbeat and blood to life. Important aspects of brain-death and transplantation in Japan are discussed by Dr Masahiro Morioka in his website: <http://www.lifestudiesnetwork.com/specialreport01.html>
As for Israel, the basic spiritual source, the Bible, is ambiguous. One verse says: "And the Lord, God formed the human of the dust of the earth, and breathed into his nostrils the breath of life, and the human became a living being". (Genesis: II,7) This has been used (together with a Mishna in Tractate Yoma) to argue that the ability to breathe is the basic criterion for human life. So since the controls for spontaneous breathing are in the brainstem, the death of the brainstem is death. But the Bible says in another place: "Only be sure not to eat the blood, for the blood is the life...." (Deuteronomy XII,23) So one can as easily argue that the circulation of blood is the basic criterion of life. So as long as the heart is beating and blood is circulating, one is alive.
Israeli law and the Chief Rabbinate (the major government-established religious authority) recognize brain death and both allow and encourage major organ donation. But a large number of other religous authorities in Israel refuse to accept heart transplantation. Their reasons are not simply a matter of religious faith, but based on scientific and clinical evidence of the kind cited in Truog's articles (cited above). But their conclusions from the evidence are of course the opposite of Truog's.
As for method's of determining brain death based on advanced imaging techniques, some rabbis argue that it is not necessary to use such procedures unless there is a doubt whether the patient is dead or alive. But if the patient should be alive (although dying) then subjecting the patient to these procedures is unnecessarily disturbing, and perhaps hastening the death, of a dying patient. (FL)
BRAIN NEUROTRANSMITTERS: (Greek: neuron 'nerve' + Latin: transmittere 'to transmit') A substance produced in and released by one neuron, that diffuses across a synapse and excites or inhibits the postsynaptic neuron or neurones. There are four principal neurotransmitters in the brain; dopamine, noradrenaline (norepinephrine), serotonin and acetylcholine and together they balance physical health and the chemistry of mood. Dopamine and noradrenaline are both members of the catecholamine family because they are produced from tyrosine, an amino acid present in the normal diet. Serotonin, an indoleamine, is a close cousin and manufactured from another dietary amino acid called tryptophan. Dopamine, noradrenaline and serotonin are collectively known as monoamines and, together with another monoamine acetylcholine, which is more involved in muscle movement and thinking than in mood, they are the key brain messengers maintaining the flow of information across the synaptic junctions of the limbic system. The limbic system has three major functions; maintenance of homeostasis, development of nurturance skills and monitoring emotion. When, for whatever reason, the balance of these neurotransmitters is disturbed, emotional regulation becomes unstable and in those individuals genetically vulnerable to bipolar disorder, for example, the syndromes of melancholia and mania may develop. In cases of severe mania, acute schizophrenia or psychosis, it is dopamine which dominates the pathways of limbic communication. Antidepressants and many mood-altering drugs - including those that produce addiction; such as amphetamines or cocaine - similarly achieve their behavioral effect by blocking or mimicking neurotransmitter activity and altering the messenger balance at the synapse and the homeostatic mechanisms that regulate synaptic transmission (Greek neuron nerve + Latin transmittere to transmit) (see UNIPOLAR DEPRESSION; BIPOLAR DEPRESSION; NEUROHORMONE; DEPRESSION; ADDICTION).

BRAINWASHING: See PROPAGANDA.
BRCA1, BRCA2 GENES. Major breast cancer associated genes. Mutations in these genes lead to predisposition to breast and ovarian cancers. Their normal counterpart code for ubiquitously expressed proteins that are required for cellular proliferation, homologous recombination and DNA repair and transcriptional regulation. Since mutations in the gene are not causal for cancer development, and many different mutations have been found in the different populations at risk so far analyzed, counseling in female carriers of mutations is a delicate issue. Scientists from the University of Utah and the US company Myriad Genetics discovered the gene in 1994. A patent has been received by them for normal gene sequence, various mutations and diagnostic tests, which has raised controversy. (GK, JA).
'piece of loaf') S
taple food made of usually leavened moistened flour , kneaded and baked. As the basic dietary component going back thousands of years, humans have enjoyed a special cultural and spiritual relationship with bread. We need a high glucose intake for our brains and cereal metabolism is the best way to secure this; thus as the single most consumed foodstuff it also serves as a widespread symbol supporting livelihood - "Give us our daily bread" or "Bread winner" and of friendship or hospitality "Break bread" (Old Teutonic
piece of loaf). (IP)
BREAST CANCER. One of the most frequent cancers in wealthy countries. Many genes contribute to its development. To date, two of the high risk factor genes have been cloned, whose mutations have been associated to the development of the disease in family as well as sporadic forms of the disease.

BREEDING : Biological process of producing a progeny with desired trait in plants and animals under specific conditions. Involves identification and control of human of human-use-value traits in further offspring. Enhancement of recognizable trait by human selection yielding improved varieties/breeds, e.g. Color, height, yield; or to yield better products e.g. good barley to make whisky. Compare to - Back cross - cross breeding of F1 hybrid offspring with one of the parents varying in their toxicity; Crosses - breeding different parental stocks. (JA)

Title of Gautama Shakyamuni, born in Nepal, approx 6th century bce. Gautama was born to a wealthy family, and at first his parents shielded him from the unpleasantness of the outside world. However, eventually Gautama was faced with real-life examples of sickness, poverty, old age and suffering. These things troubled him, and he set out to examine the problem of suffering in the world and how to eliminate it. A key point in his teaching is that if an individual is unable to break free from the cycle of suffering in this lifetime, that individual is reborn to continue the quest for the release from suffering. (see KARMA) Buddha's teachings focus on the problem of suffering, its causes, and ways to reduce and elminate it. In a more general sense, the term "buddha" is applied to other individuals who have managed to achieve the release from the cycle of suffering. (AG)
BUDDHISM Belief in the philosophy of Buddha and the lifestyle based upon it. Two major branches of Buddhism are Theravada (school of the Elders) and Mahayana (lit. "Great Vehicle"). (AG)
BUFFER ZONES: Intervening areas of natural vegetation which provide National Parks and other forests protection from edge effects and the encroachment of other impacts. Buffer zones are important to reduce habitat fragmentation and demonstrate good environmental management policy outside parks and preserves. They provide wildlife corridors and improve the aesthetic values of suburban and rural landscapes. (See WILDLIFE CORRIDORS, EDGE EFFECTS, HABITAT FRAGMENTATION, MULTIPLE USE ZONES) (MP)
BUG: 1. An error in computer programming, for example incorrect coding of an instruction (syntax error) or instructions unable to provide the required solution to a particular problem (logic error). (See DEBUG, PROGRAM, COMPUTER VIRUS). 2. A tag or sensor such as a microphone or locator, usually covertly placed for the purposes of spying and strategic surveillance. Sensor networks and smart dust are in thying invertebrates, especially beetles (Coleoptera) and cockroaches (Blattodea). (See COLEOPTERA) (MP &IP)
An eating disorder - also called binge eating - characterized by recurrent episodes of binge eating and a feeling of lack of control of eating behavior during eating binges which are interspersed by self-induced vomiting, use of laxatives or diuretics, dieting and rigorous exercise all to prevent further weight gain. Bulimia may cause hormonal disorders followed by depression, disturbed menstrual cycles and fertility problems (Greek

BULLY: 1. a person who browbeats smaller or weaker people 2. Archaic : a man hired to do violence. (IP)
BURIAL: Placing of the body in the ground after death. This method of showing respect for the human body has been practiced since ancient times in many cultures around the world. It is the preferred method of dealing with the human body after death in Jewish, Muslim and many other traditions. Burial sites have been found around the world from prehistoric times onward. In many traditions, a place where humans are buried is a sacred site, or a site which is to be avoided. In Jewish tradition, the kohen (priest) is forbidden to approach a burial site, except in the case of the closest relatives and a person who has no relatives, and therefore has no one to look after burial procedures. (AG)
BUSH : in Australia and Africa represents the wild uncultivated indigenous forests and scrublands - countryside left in its native state; hence, 'go bush' or escaping one's usual surroundings for the natural landscape; that is, running wild. (See BUSH MEDICINE). (IP)
BUSH MEDICINE : The total sum of Australian Aboriginal knowledge accumulated over thousands of years in the use of indigenous plants and herbs with curative properties. On the whole, plant remedies represent a universal and continuous form of medicine with its chief therapeutic products becoming any nations specific "folk medicine". Australian bush medicine is based on word-of-mouth; that is, the digenous plant used in bush medicine has specific meaning and effects, either in isolation or plant remedies that compensate for one anothers undesirable properties. For example, a laxati eucalypt ingredient to improve the taste. Simiing metabolic activity. The basic assumption be influences of natural organic substances essen terms of proportions rather than measured amounts providing a relative simple holistic treatment in harmony with life and Nature - something that modern medicine lacks.
Since the accepted wisdom behind bush medicine is that the body is capable of healing itself once the proper conditions are provided, treatment remedies are designed to neutralize and eliminate from the body the harmful substances that impair its power to heal itself. Of course this kind of wisdom, which has been largely lost and replaced by modern - European mostly - beliefs and by synthetic pharmaceuticals, is common to many traditional remedies. However, in a new spirit of inquiry into Aboriginal heritage, the therapeutic property of Australian plants has become an important topic of study, documentation and retrieval of lost knowledge. In future the best of traditional Australian medicine may comfortably co-exist with the best of western-style medicine - there is space for both.

BY-CATCH: The accompanying organisms contained in a fishing catch which are incidental to the targeted effort. By-catch comprises a large proportion of the catch from commercial fish and prawn trawlers, impacting for example juvenile fish, invertebrates, turtles, coral and benthos. The portion of the by-catch returned to the sea, mostly dead or dying, is termed the discard catch. Technology and regulation help reduce ecological impacts, for example closure of trawling in estuaries to allow stock replenishment, catch-excluding devices for turtles and other animals, selective fishing gear, and a culture of catch-and-release.

The killing (e.g. by hanging, electrocution, lethal injection or shooting) of a convicted criminal. A significant number of countries have by now outlawed capital punishment and those which still practise it use it for fewer crimes, often only murder, than was once the case. Often cited intrinsic arguments against capital punishment include the assertion that only God has the right to take human life. However, in some societies a significant proportion of people don't believe in God, and, anyway, many religions permit people to be killed in certain circumstances, e.g. in war. One intrinsic argument in favour of capital punishment is that the right punishment for certain crimes - e.g. murder, treason or piracy - is to forfeit one's life. There are also consequentialist arguments both for and against capital punishment. Indeed, much of the information that would be needed to reach a rigorous consequentialist conclusion is uncertain. For example, does capital punishment act as a significant deterrent to crime and how often is the wrong person killed under capital punishment? (MR)
CAPITALISM : Capitalism is any economic system in which people make money out of other people's labour. It is generally the goal of capitalists to make as much money as possible by paying the labourer just a little less than one needs to support a family. But labour movements have forced employers, under threat of strikes, sometimes violent, to be more generous in their salaries. It used to be thought that socialism was the opposite of capitalism. But deeper analyses (such as by movements like the Industrial Workers of the World) pointed out that the leaders of socialist communities or societies are also living off the work of others, but calling themselves "leaders" or "managers" or "statesmen" rather than "capitalists". (FL)
CARBON: Sixth ELEMENT (q.v.) in the Periodic Table. Along with hydrogen, oxygen, nitrogen and a few other elements, carbon is an essential constituent of all known life. Chemicals with more than just one or two carbon atoms are said to be 'organic'. All other chemicals are inorganic. (MR)
CARBON-BASED ELECTRONICS: See MOLECULAR ELECTRONICS
See ORGANIC CHEMISTRY.
CARBON CREDITS: See ENVIRONMENTAL COMPENSATION, GLOBAL WARMING.
CARBON CYCLE: The redistribution of carbon between organisms and the atmospheric, oceanic and terrestrial compartments. The cycle is primarily driven by the action of biological processes such as the removal of carbon from the atmosphere during photosynthesis and its return to the atmosphere during respiration. Human utilization of fossil fuels such as oil, natural gas and coal, have resulted in carbon dioxide being produced and released into the atmosphere faster than it is being removed by living organisms (see CARBON, GREENHOUSE EFFECT, NITROGEN CYCLE, PHOSPHORUS CYCLE). (MP)
CARBON DATING: See RADIOCARBON DATING.
CARBON DIOXIDE : (Chemical formula CO 2 ; Latin carbo 'coal' + Greek dis 'twice' and oxys 'sharp'). A colorless, odorless gas produced naturally by the complete oxidation of carbon. It occurs in the atmosphere 0.03% and is found in solution in sea-water and rivers. CO 2 plays an essential part in metabolism and ecosystem stability - a waste product of cellular respiration (carbohydrate and fat metabolism) utilized by plants during photosynthesis. That is, plants absorb carbon dioxide to obtain the carbon needed to build their tissues while plants and animals expel the gas as a product of food oxidation. In its solid form (dry ice) it is used in the treatment of some skin conditions. It is also used in fire-extinguishers, aerated water and in the bakery industry where bubbles of carbon dioxide liberated by yeast (or baking powder) in the dough lightens the dough rendering it more palatable.

CARDIOVASCULAR DISEASE : (Greek kardia 'heart'). Any abnormal condition characterized by the dysfunction of the heart or blood vessels such as arteriosclerosis, rheumatic heart disease and systemic hypertension. In affluent western societies such as the USA and Australia, cardiovascular disease is the leading cause of death. (See STRESS; DISEASES OF ADAPTATION; GENERAL ADAPTATION SYNDROME). (SG2+IP)
CARING: With the rise of VIRTUE ETHICS (q.v.) a caring person is increasingly recognised in ethics as a particular instance of a good person. Caring is not to be equated with BENEFICENCE (q.v.), having a more relational quality to it. FEMINISM (q.v.) has seen caring as a central human virtue yet one that has traditionally been undervalued both in academic ethics in particular and in patriarchal societies more widely. It has been strongly argued that caring is central to such professions as nursing and teaching. (MR)
CARRIER : Someone who may transmit a recessive genetic condition but who normally does not show any evidence of the disease (DM). It is possible to distinguish two types of carriers, sex-linked and autosomal carriers. In the first case, only women are carriers, and may transmit the disease gene to either sex of her children, but only boys will be affected in a ratio of 1 in 2 (50% chance). In the second case, if both parents are carriers of a mutant gene, any child has a chance of 1 in 4 (25%) to suffer the disease (GK).
: Used to detect individuals who possess a single copy of a gene which follows an autosomal recessive pattern of inheritance. Such an individual will not normally develop any disease or disorder but may pass on the gene to his or her offspring.
CARRYING CAPACITY: Carrying capacity (represented by the symbol K in ecology) is the maximum population density able to be sustained by an environment for a prolonged period of time without causing lasting damage or degradation. The concept also has applications to human ecology, for example in international development, food production or ecotourism management. (See SUSTAINABILITY, LIMITS OF ACCEPTABLE CHANGE) (MP)
CARSON, RACHEL: (1907-1964). Biologist and writer whose 1962 book Silent Spring has widely been hailed as heralding the environmental movement in the West. Carson initially specialised in English but her ambition to become a writer was initially overcome by her interest in natural history. For much of her working life she was genetic biologist and then editor-in-chief for the US Fish and Wildlife Service. In Silent Spring Carson presciently argued that chemical pollution, particularly through the widespread use of agricultural pesticides, was both killing wildlife and upsetting the balance of nature.

CATALYST : 1. A chemical which remains unchanged but acts to initiate or increase the rate of a chemical or biological reaction. 2. More generally, a catalyst may be any substance, course of action or idea which initiates or increases the efficiency of any process of change. (See ENZYME) (MP)
CATHEKONIC ETHIC : A philosophical principle that deals with the relationship between parts and the whole. (JA)
CATHOLIC: Universal. So, strictly, the Catholic Church is either the whole body of Christians or the whole Christian Church before it separated into the Greek (Eastern) and Latin (Western) branches. In practice, though, the Catholic Church is widely understood as the Roman Catholic Church, namely that part of the Latin Church which remained under Roman authority after the Reformation. Roman Catholic theology has been and remains important in much medical ethics, for example with regard to the PRINCIPLE OF DOUBLE EFFECT (q.v.) and such issues as ABORTION (q.v.), CONTRACEPTION (q.v.) and EUTHANASIA (q.v.), with Roman Catholic teaching being strongly and consistently against all three.

CAUSATION: An interaction which produces or brings something about, pertaining to the cause and effect relation. Causes have consequences; affects have effects; act-contact-impact over time. Causation implies a pre-impact necessary connection and constant conjunction . Correlation or logical necessity may not necessarily indicate causation. Many things have a plurality of causes, the multitude of which leads to ultimate causation and the freedom/determinism debate. (See CORRELATION, AFFECT, EFFECT, PROOF, ENVIRONMENTAL IMPACT) (MP)

CENSUS: 1. Statistics: a census is a survey which investigates every member of a statistical population to determine its parameters. 2. Sociology: a government- sponsored obligatory survey of all individuals in a country or region. Early censuses (from 1801 in Britain) were in the form of simple head-counts, but today census forms ask for a wide range of personal and household information. Privacy and trust issues make it preferable that the census be anonymous. Census data may be disaggregated to provide localized political, academic and market research. Social statistics are an important resource for investigating trends in social well being, stratification and sustainability. (MP)
CENTIGRADE : See CELCIUS DEGREE (°C).
CENTENARIAN: A person who has reached the age of one hundred years. (See LIFE EXTENSION) (MP)
CENTIMORGAN: A unit of measure of genetic recombination frequency. One centimorgan is equal to a 1 percent chance that a genetic locus will be separated from a marker due to recombination in a single generation. In human beings, 1 centimorgan is equivalent, on average, to 1 million base pairs. The recombination frequencies between two loci on a chromosome are not the same in both sexes, and may be quite different from one chromosomal region to the other. Therefore, genetic distances measured in centimorgans are just an approximate measure of the physical distance as measured in base pair units. (DM+GK)

CERVIX: (Latin cervix "neck") that part of the uterus that protrudes into the cavity of the vagina - also called the "neck of uterus". Cancer of the cervix is a major cause of death among women (see CERVICAL CANCER; CERVICAL MUCUS; OVULATION METHOD OF FAMILY PLANNING). (IP)
CERVICAL CANCER: a neoplasm (abnormal development of cells that may be benign or malignant) of the uterine cervix that can be detected in the early, curable stage by the Papanicolaou (Pap) smear test. If left untreated cervical cancer invades the adjacent tissues and organs and eventually metastasizes through lymphatic dispersal. Carcinoma in situ , on the other hand, may be easily treated by excision or cryosurgery. Factors, which may be associated with the development of cervical cancer, are coitus at an early age, relations with many sexual partners, genital herpesvirus infections, multiparty, and poor obstetric and gynecologic care (see PAP SMEAR TEST). (IP)
CERVICAL MUCUS: a secretion of the lining of the upper portion of the cervical canal of the uterus. The mucus" consistency and appearance changes throughout the menstrual cycle. Around the time of ovulation, the volume of mucus increases and becomes thin, clear elastic, and easily penetrable by sperm; during the infertile periods of the menstrual cycle the mucus is thick and less penetrable to bacteria and sperm. The cervical-mucus method of birth-control is based on the detection of this change in the vaginal mucus in order to avoid intercourse during the likely fertile period. (IP)

(See TIME, PROCESSES)
CHAOS THEORY: The notion in the natural sciences that a very small change in a system may have massive, unpredictable consequences. Memorably summed up by the 'Butterfly effect' in which it is possible, though of course, not certain, that the beating of a butterfly's wings in one part of the world may lead, a few weeks later, to a storm thousands of miles away. The indeterminacy of Heisenberg's Uncertainty Principle (q.v.) and chaos theory effectively ended belief in a Newtonian, determinate world-view in which an accurate description of a system allows its future to be predicted absolutely. Nowadays, for example, scientists predict that however accurate our measuring instruments and powerful our computers we will never be able to predict local weather variations more than a couple of weeks ahead. (MR)

CHEMOTAXIS the process whereby bacteria that possess flagellae for propulsion sense a concentration gradient of a chemical substance in the medium and move either toward or away from it (see TAXIS). IP
CHEMOTHERAPY the treatment of diseases with chemical agents. The procedure involves the exploitation of biochemical differences between the disease process and the host tissue in order to interfere selectively with the disease process; for example, in selectively destroying cancer cells. Modern biochemical pharmacology is based on designing specific inhibitors targeted to discriminate against a metabolic process that is specific to the pathological condition. (IP)

CHILD ABUSE: physical, sexual, or emotional mistreatment of an infant or child by any adult or adults. Major therapeutic and statutory concerns are identifying dysfunctional family members, friends or relatives and the children at risk. A duty of care falls on any individual who is confronted with children with obvious physical signs (the "battered-child syndrome") such as burns, welts, bruises, frequent physical mishaps/fractures, suspected sexual molestation, or signs of emotional distress and overall failure to thrive. Characteristically, abuse may be seen as the final behavioral consequence of multiple factors compounded by a variety of stressful circumstances; such as drug abuse, lack of emotional support within the family unit or lack of nurturing experience, possibly by victims of child abuse themselves. Child Sexual Abuse is the involvement of dependent, developmentally immature children and adolescents in sexual activities to which they are unable to give informed consent, and which violate the social taboos of family responsibilities. Despite recent insights, there still remain a large number of uncertainties and confusions surrounding child abuse. To some degree, this may be due to the particular protection society affords to "family business" and problems adults have in dealing with sexuality in themselves and in children. Additionally the area of child abuse is difficult to research objectively because it raises issues about power, secrecy, shame and guilt. (See ABUSE; elder abuse ; DRUG ABUSE). (IP)

(See PERSISTENT ORGANIC POLLUTANTS) (MP)
CHLOROFLUOROCARBONS OR CFCs: Volatile compounds commonly known as "Freons". The chemicals have been used in association with refrigerant fluids, solvents, aerosol propellants and blowing agents in the fabrication of foam plastics. Their extraordinarily high stability enables them to persist in the atmosphere and to enter the stratosphere where they are the major culprit in ozone layer depletion (see OZONE HOLE). Lag times before the effects of human-driven change emerge can often be long; for example, CFCs released into the atmosphere now will damage the ozone layer in thirty to eighty years time, risking a false sense of safety.

CHRIST, JESUS: Central figure of the Christian faith, understood in a unique way as God's Son and, along with God the Father and the Holy Spirit, as one of the Trinity. Seen by some other faiths as a great prophet. (MR)
CHRISTIAN ETHICS : System of belief about right and wrong actions and attitudes derived from, or at least strongly influenced by, Christianity (faith in Jesus, the Christ as the one son of God). Much Christian ethics derives from scripture, so discussions / disagreements among Christians about such matters as divorce often cite particular verses in the bible that deal with the issue. Many of todays ethical issues, of course, lack much or any specific scriptural reference e.g. genetic engineering, euthanasia, cloning, and the conservation of endangered species. Christian ethicists typically still draw on more general scriptural principles e.g. about the place of God in creation, and stewardship as well as reason and tradition when debating such issues. (MR)
CHRISTIANS : The disciples of the Lord Jesus Christ were called Christians in the city of Antioch (Bible. Acts. 11:26). Their life style was so unique that King Agrippa replied St Paul " Do you think that in such a short time you can persuade me to be a Christian" (Acts. 21:28). Till about 300 AD, Christians were persecuted (1 Peter 4:16) like the people living in Cappadocia (now in Turkey). Although there are two major divisions, namely Protestants and Roman Catholics, these groups are not found in the Bible, there are now many sects among Christians, which are based on minor doctrinal differences.

CHRONICALLY ILL See CHRONIC DISEASE, CRITICALLY ILL, DISABLED, REHABILITATION, TERMINALLY ILL.
CHRONOCENTRISM: (From the Greek "chrono-"= time + center+ ism) A belief or viewpoint which holds that a particular time period is better than others, and that the society which lives in that time period is superior to societies which live/d in other time periods. During the 20th century, many new terms were coined to acknowledge the growing awareness that being self-focused (either as an individual or as a group) has negative aspects, and that there are multiple viewpoints and perspectives that need to be recognised. The terms "racism", "sexism", "antisemitism", and "ageism" demonstrate examples of discrimination applied to certain groups of people, based upon the conditions of their birth, whether gender, ethnicity, race or religion are a factor. The coining of "ageism" also shows awareness of a person's age and how that affects the way that person is viewed in society. There is also recognition of the problem of discrimination of people with disabilities of various sorts. However, there is another subtle form of self-centered thinking, which has not been acknowledged with a special term, and this is why the term "chronocentrism" is being offered.
It is difficult to claim that chronocentrism is a form of discrimination in the usual sense of the word. The reason is that generally chronocentrism is applied towards people who are not currently alive. Chronocentrism is not quite the same as discrimination against people who were born earlier, and thus lived their formative years in a different societal and technological setting. It is also not quite the same as discrimination applied towards a traditional society that is considered "backward". In both cases, the discrimination is applied to people, and the negative attitude towards those people's ideas is given as the reason for the discrimination. However, in the case of chronocentrism, the negative attitude is applied to a society, rather than towards a particular person. That society is held to be "inferior" to one's own. In some ways, this parallels negative attitudes towards foreign societies that are contemporary with one's own. However, in the case of chronocentrism, the negative attitude is applied even towards one's own society of a different time period. While this does not have a direct affect on a particular human being, it can have affect on a large number of people, because chronocentrism is directed at the values and lifestyle of society. Derivative forms include "chronocentric" for an adjectival form, "chronocentrist"- "one who practices chronocentrism". (AG)
CHU HSI: (pinyin spelling Zhu Xi) (1130-1200) Confucian scholar and philosopher. His most influential work included commentary of the classical Confucian texts.

: Practiced for religious reasons by Jews and Muslims, and for medical reasons to a large extent in the United States and Canada. Reviews conducted by committees of the Canadian Pediatric Society and the American Medical Association acknowledged some benefits of the operation for reducing sexually transmitted disease, penile cancer and neonatal urinary tract infections. But they also noted dangers of surgical error and complications. Both the benefits and the risks are statistically small, and they are close to equal. So both committees recommended against routine medical neonatal circumcision. Their reports were published, however, before more recent research suggesting that circumcision may protect against AIDS because receptors for the HIV virus are located on the inner side of the foreskin and at the point where the foreskin is attached to the penis.
There is a debate in Jewish tradition between those who believe, with Rabbi Akiva and Rabbi Saadia Gaon, that circumcision improves the baby by removing an unnecessary piece of skin, and those who believe, with Maimonides (q.v.) that nature never does anything unnecessarily, and that whatever nature does routinely (as opposed to mutations) is for the good of health. Maimonides believed that the foreskin performs a perfectly healthy function, contributing to pleasure and erectile Function, and that Jews are commanded to remove it in order to reduce sexual pleasure to no more than is needed to perform the Biblical commandment to be fruitful and multiply. There are religious Jewish movements today, associated with Reform Judaism, who want to do away with infant circumcision. (FL)
CIRCUMCISION, FEMALE : See FEMALE GENITAL MUTILATION.
CIRCUMSTANTIAL EVIDENCE: Common-sense notion of indirect information that suggests the most likely explanation for some event. For example, if a gun shot is heard from a room with only one entrance/exit and I then walk out and others then find a dead woman in the room, there is circumstantial evidence that I killed her. Of course, it could be that she killed herself, that I shot her but she was already dead, etc.. (MR)

CLASH OF CIVILIZATIONS: A popular term emphasizing the role of inter-civilizational differences as one of the causes of wars, cold war and international tension, for example contrasts between the dominant religious/political/ideological systems of the Sinic, Islamic and Western civilizations. Popularized by Samuel Huntington's 1997 book of the same name, the clash of civilizations hypothesis experienced a revival after the 2001 terrorist attacks upon America. Although a useful basis for peace research and the search for common philosophical ground, care should be taken not to promote the concept of a divided world. Such generalizations should not ignore the positive international effects of multiculturalism, trade, travel and human diversity, nor the fact that civilizational differences are often merely used as an excuse to justify war - the true underlying reasons for war usually more directly involve power, territory, resources and/or economics. (See CIVILIZATION, WESTERN CIVILIZATION) (MP)
CLASS: (Latin: classis "rank") 1. Sociology: A division or classification of people by economic, cultural or social ranking, or containing members sharing common attributes. Social rank, economic stratum and cultural caste may be useful classifications for understanding socioeconomic systems, but should be broken down to bring people together rather than emphasizing difference and encouraging prejudice.

CLAUSEWITZ, CARL VON: Prussian-born military officer and strategist Carl von Clausewitz (1780-1831) was the author of On War, considered one of the definitive collections of insights on the subject. Although his work has negligible emphasis on morality or war ethics, its contributions to the theory and nature of war include valuable insights. Clausewitz argues that politics is the source and objective of war, which is mere "continuation of policy by other means". (See INSTITUTION OF WAR) (MP)

CLINICAL ETHICS COMMITTEES : Institutional committees established to protect the welfare of patients. (See ETHICS COMMITTEES). (DM)
CLINICAL TRIALS: A general term for attempts to make testing of new drugs as scientific as possible. Clinical trials are the central method for applying the ideal of "Evidence Based Medicine", i.e. allowing into the physician's pharmacopoeia and clinical repertoire only those drugs and techniques which have been scientifically proved to be safe and effective. This is still far from reality, however, as it is generally understood that the majority of treatments in use today are still based upon the collective experience of the profession, and not on scientific evidence. Also, controlled clinical trials of surgical techniques lag far behind those of drugs.
After a new drug is studied in vitro and with animal subjects (a bioethical issue in itself) controlled clinical trials are performed on human subjects, ideally with the free informed consent of the patient, although this is problematic in pediatric, psychiatric and geriatric medicine. Trials are "controlled" in that the test group may be compared with a group which receives no treatment, or with a group receiving an existing treatment, or with a group receiving a placebo. The most recent version of the Helsinki Declaration (q.v.) however, recommends using an existing treatment for comparison rather than a placebo. The bioethical reason is that patients may find that their only hope for cure is to enter a trial and take a risk of getting the placebo rather than the real treatment. This would be a form of coercion. Trials are also supposed to be "double blind" in the sense that both the physician and the patient are not supposed to know who is getting the treatment and who is getting the placebo.
Clinical trials are usually sponsored by the corporation which has invested in developing the drug, and which hopes to eventually make a profit. This can lead to many bioethical problems. For example, there is little uniformity among contracts between drug companies and physician-researchers, but some have clauses forbidding the physician to divulge to a third party or to publish information learned during the conduct of the trial, unless the drug company gives permission. A physician, whose first loyalty must be to one's patients, and to patients in general, has a bioethical dilemma when one has concluded that the drug is detrimental to the patients, but the drug company is slow about giving permission to publish this information. By the time the drug company gets around to giving permission, some patients can be hurt. Physicians who have seen their loyalty to their patients, and their academic freedom to publish data which can prevent future harm to patients, as more important than their contract with the drug company, have not always been supported by their hospitals and universities. (FL)
CLINICAL TRIALS, INFORMED CONSENT IN PEDIATRIC, PSYCHIATRIC AND GERIATRIC : The requirement for freely-given informed consent becomes problematic when the patient is incapable of clearly understanding and freely assenting, or when the patient's competence is on the borderline. Such cases may be more the rule than the exceptions in hospitals, where even the most sane, intelligent and well-informed patients may be in pain, in fear and under great emotional pressure. These problems are amplified when the patient is a baby, or mentally ill or a geriatric patient in or close to dementia, or when the patient is in coma. In order to allow research to proceed, the concept of a "proxy" or "surrogate" was devised. A parent of a baby, for example, or a family member of an adult incompetent patient, is allowed to give the "free informed consent" thereby preserving the ideology of "autonomy". But this is a legal and bioethical fiction.
When the treatment under trial is indicated for the clear medical benefit of the patient, then there is room for proxy assent. Obviously a parent can impose treatment (an unpleasant vaccine injection, for example) when it is clearly for a baby's good. But more attention must be paid to formulating ethics of interventional trials on healthy babies, or on other patients who are incapable of giving free informed consent by themselves. (FL)

Direct causes may be poor sperm or egg quality of a male or female cocaine user, and/or drug-effects in utero adversely affecting the developing embryo and fetus. Contributing causes may be poor nutritional habits and abuse of additional substances such as alcohol and tobacco (see COCAINE HYDROCHLORIDE; CRACK; ADDICTION). (IP)
COCAINE HYDROCHLORIDE: a crystalline alkaloid derived from coca leaves but can also be manufactured synthetically. Traditionally used as a local anesthetic cocaine, when taken internally, is highly toxic with serious psychotropic effects. It is one of the most powerful dopamine-enhancing drugs and achieves its effect at the nerve synapse by blocking the neurons recycling system for dopamine; thus dramatically increasing the amount of dopamine messenger available to stimulate neurotransmission. Throf excitability characterized by euphoria, optimism, increased energy and decreased need for sleep. The euphoric effect lasts about 30 minuttement, restlessness, incoherent speech, fever, hypertension, and cardiac arrhythmias which can lead to convulsions, respiratory arrest and ssion so frequently abuse it (see CRACK; COCA; COCAINE BABIES; ADDICTION). (IP)
CODE: A set of principles (see GENETIC CODE).
CODE OF HAMMURABI: (actually should be Hammurapi, based on Ugaritic texts) Major lawcode of ancient Mesopotamia. This lawcode is named for Hammurapi, the king 6th king of the first dynasty of Babylon (1792-50 bce). On the stele of Hammurapi, the king is protrayed as receiving the lawcode from Shamash, the sun god. The laws in the code demonstrate three levels in society: the awilum (free man), the mushkenum (the dependant, of somewhat lower status than the awilum), and the wardum (slave). Each is judged according to his social class, and greater damages are awarded to an awilum who was injured than a mushkenum or wardum who was injured. The principle of "an eye for an eye" is applied to the extreme in this lawcode. Many of the cases in the code of Hammurapi are dealt with in the Torah as well, and so, this lawcode has become a popular source of comparison between Babylonian law and Jewish law. The text of the code is written in the Babylonian dialect of the Akkadian language. (AG)
CODES OF CONDUCT: See ENVIRONMENTAL CODE OF CONDUCT.
CODES OF ETHICS : Systems of principles or rules of ethical professional conduct, usually established by professional societies. An ethical code governs , for instance, the use of a technology or the Patient -Doctor relationship. Ethical considerations form a guideline evoking acceptable behavior based on moral values and practical experiences. It serves as a regulatory principle e.g. marketing and labeling of GM food, confidentiality in the treatment of people living with HIV and AIDS. (DM, JA).
CODEX ALIMENTARIUS COMMISSION (CAC):
The joint FAO-WHO Intergovernmental body that makes legally binding standards for international regulation of food quality, safety and trade.
CODOMINANT. 1. From the phenotypic point of view, status of the alleles of an autosomal gene, where both contribute to the phenotype due to that particular gene in a heterozygote. 2. From the molecular point of view, differences in the two copies of a specific gene in a heterozygous person, that can be visualized by molecular methods (i.e., two sizes of a STR or a VNTR, or presence/absence of a restriction site from a RFLP marker). (GK)
CODON: A sequence of three DNA base pairs which codes for an amino acid. Consist of three nucleotides, a three lettered code word (e.g. UUU for phenylalanine/AAA= lysine) for each of 20 amino acids. (DM, JA)
COEFFICIENT VARIATION: It is the measure of how much bigger is the standard deviation when compared with the mean (JA)
COELENTERATES: Coelenterata is previous taxonomical terminology for the phylum Cnidaria. The coelenterates (cnidarians) include corals, hydrozoans and jellyfish. (See CNIDARIA) (MP)
: An action taken to force another to adopt a behaviour. Issues include force feeding, and mandatory programs as compared to voluntary programs. (DM)
COGNISANCE: (Latin: cognitio 'apprehend') 1. knowledge, awareness, perception, bioethics self-awareness 2. to investigate for the purpose of knowing, to understand, learn knowledge, recognition by observation or information 3. consciousness, state of awareness [Latin cognitio apprehend] (IP)
COGNITIVE-BEHAVIORAL THERAPY: was conceived and developed by Aaron Beck, a professor of psychiatry at the University of Pennsylvania, and emphasizes the power of positive thinking. Basically the therapy assumes that, given accurate information, the brain can "think" its way back to health; that is, by harnessing its powerful intelligence, the brain can learn to be objective about itself and replace old destructive thinking patterns with new, constructive adaptive ones. Cognitive-behavioral therapists believe that conscious thought, rather than unconscious motivation, determines social behavior; therefore, with professional guidance, individuals can learn to change their maladaptive attitudes toward other people. This form of therapy differs from the older psychodynamic therapies by placing greater emphasis upon the active participation of the patient, with the ultimate goal being the regaining of personal control of the social environment through self-education and learned optimism. These therapies have been compared, head-to-head, with antidepressant drugs in the treatment of acute episodes of depression, and found to be effective, especially in milder illness. It seems, therefore, that thinking about how one thinks is an essential tool because it provides a sense of personal control and complements the wise use of medication (see ELECTROCONVULSIVE THERAPY). (IP)
COGNITIVE LIMITS: See IMPOSSIBILITY, UNKNOWABLE.
A set of beliefs or theories are in coherence when they are mutually supportive and none are inconsistent with any other. (See CONSILIENCE, CORRELATION) (MP)
COHORT: A group of individuals of the same age/generation within a population. It is often useful in ecological management and marine conservation to track cohorts through their life cycle within the general population. (See AGE DISTRIBUTION) (MP)
COITUS : (Latin coire to go together). An act of intercourse that usually, but not always, involves penetration of the penis into the vagina and results in sexual excitation and, as a rule, orgasm. (See COITUS INTERRUPTUS). (IP)
COITUS INTERRUPTUS : Withdrawal of the penis from the vagina just before ejaculation. It is thought to be the oldest method of contraception and is mentioned in the Book of Genesis. The method is not reliable (failure rate is above 15%) because small amounts of sperm containing seminal fluid may be emitted before full sensation leading to ejaculation is felt. Unwanted conceptions may carry the risk of conflict, resentment and prenatal/postnatal neglect. (See NATURAL FAMILY PLANNING METHODS, CONTRACEPTIVES, CONDOM). (IP)
: The insect order containing the beetles, Coleoptera is such a diverse and widespread order that beetles comprise over a quarter of all species found on Earth today. (MP)
COLLATERAL DAMAGE: (Collateral: "situated beside" + Damage: "injury or loss") A military term referring to civilian victims and casualties of military operations, including non-combatant deaths or injuries and damages to civil property. The 1949 Geneva Convention and 1977 Geneva Protocol outline internationally recognized protections for innocent civilians. Scrutinized strategic targeting with modern precision weapons has changed the nature of war in comparison to the deliberate targeting of civilian populations in World War II. Collateral damages are today generally unintentional, and can be used for propaganda purposes and war crimes allegations. The term collateral damage is a good example of the use of euphemism to render distasteful concepts obscure to the layperson. (See GENEVA CONVENTIONS, JUDGE ADVOCATE GENERAL, EUPHEMISM, REFUGEES, CASUALTIES, POST TRAUMATIC STRESS DISORDER) (MP)
A group of people who have assembled together due to similar value systems and a common cause; for example a collective farm or kibbutz. (See UNITED) (MP)
COLLECTIVE BARGAINING: The practice of reaching work and pay agreements directly through representatives of employers and employees, often bypassing workers rights protection afforded by industrial dispute institutions such as trade unions. (See INDUSTRIAL RELATIONS, INDUSTRIAL ACTION) (MP)
COLLECTIVE CONSCIOUSNESS: A hypothetical spiritual communion of all thoughts, emotions, memes and memories into a collective or super-consciousness, perhaps with emergent properties. (See COLLECTIVE MEMORY, COLLECTIVE UNCONSCIOUS, INFOSPHERE, MORPHIC RESONANCE) (MP)
The "meme pool", or shared and combined experiences and memories of the sentient animals on Earth. Although each of us has a unique set of memories, we also have shared memories of our historical record and our collective achievements and mistakes. The expansion of this shared consciousness through the promotion of learning can help to guide us towards a more ethical future in which previous human and environmental tragedies are not perpetuated. (See MEME, CULTURE, DREAMTIME) (MP)
COLLECTIVE SECURITY : This concept grew out of the Geneva conferences on disarmament after the First World War. Literally the term meant that under the covenant of the League of Nations, the member states of the League should together guarantee the security of each individual member. (See INSTITUTION OF WAR). (IP)
A Jungian psychological theory in which some collective aspects of consciousness such as community history may be imprinted in the individual unconscious mind. (See COLLECTIVE MEMORY, COLLECTIVE CONSCIOUSNESS) (MP)
COLLECTIVISM: A socio-political ideology in which means of production and control are placed with the people collectively, usually represented by the state. The emphasis is on responsibilities rather than rights, and the collective is more important than personal individuality. Collectivism may incorporate aspects of family, democracy, socialism and/or Confucianism. (See INDIVIDUALISM) (MP)
The domination of a country by the imposition of economic, religious, cultural and language practices of the colonial power upon local populations. Examples include the colonization of the African, Asian, Australian and American continents by the English, French, Dutch, Spanish and Portuguese during the 15th to 18th centuries. Most of these colonies have now been granted political autonomy, although usually with the maintenance of cultural and economic ties. Any Western expansionist policies left over from the Ages of Discovery and Imperialism have today been replaced by economic ones. (MP)
COMA : Unconscious state, which may occur after a traumatic accident or stroke. Usually afer two weeks a person is either dead, or enters persistent vegetative state. (See BRAIN DEATH, PVS). (DM)
COMMENSALISM: A symbiotic relationship in which one species gains some benefit from an association with another species, but in which the second partner has neither benefit nor detriment. An example of a commensal organism is the rainforest epiphyte, which grows on the trunk of a host tree and gains the advantage of support, shelter, access to leaf litter, water flow and sunlight. (See SYMBIOSIS, PARASITE). (MP)
COMMON GOOD: The good of every body. (See JUSTICE). (DM)
COMMON LAW 1. the part of a system of laws of any state or nation that is of a general and universal application 2. the system of laws originated and developed in England, based on court decisions, on the doctrines implicit in those decisions, and on customs and usages, rather than on codified written laws (see STATUTE LAW) (IP)
COMMON SENSE: The basic level of practical knowledge and judgment that we all need to help us live in a reasonable and safe way. Common sense varies between people and culture, though it is still called "common". (DM)
COMMONS: Land not owned privately but in public ownership. (See TRAGEDY OF THE COMMONS ) (MR)
COMMUNICABLE DISEASES : Diseases that can be transferred between individuals, infectious diseases. (DM)
COMMUNICATION: The sending and reception of useful information between two or more parties. (See DISCOURSE ) (MR)
The belief in a society without different classes in which the methods of production are owned and controlled by all its members and everyone works as much as they can and receives what they need. It is a system of political and economic organization in which property is owned by the state or community and all citizens share in the common wealth, more or less according to their need. Many small communist communities have existed at one time or another, most of them on a religious basis, generally under the inspiration of a literal interpretation of Scripture. In 1848 the word communism acquired a new meaning when it was used as identical with socialism by Karl MARX and Friederich ENGELS in their famous
. They and their followers used the term to mean a late stage of socialism in which goods would become so abundant that they would be distributed on the basis of need rather than of endeavour. The Bolshevik wing of the Russian Social-Democratic Workers' Party, which took power in Russia in 1917, changed its name to the All-Russian Communist Party in 1918. Thus the Soviet Union and other states that were governed by Soviet-type parties were referred to as Communist and their official doctrines were called Communism, although in none of these countries had a communist society in its original meaning been fully established. (DM)
COMMUNITARIANISM : An ethical and political philosophy which combines meritism in the allocation of rights with collectivism in regard to freedom. Central to the communitarian idea of democracy is that citizens' true opinions can only be detected by observing the community's traditional responses to ethical issues; that is, the citizens have to condone traditional values such as, for example, the prohibition of contraceptives on religious grounds. There are two main dividing lines between the most important late twentieth-century theories of ethical and political philosophy. The first distinction concerns the nature of human individualism; that is, freedom or liberalism. The second distinction concerns the nature of human rights or entitlements of help from others in situations where they cannot cope for themselves. These categories can be divided into the ethics of self-actualization and the ethics of caring and are, clearly, interrelated since the second (freedom from need) is a prerequisite to the first (liberty to freely express ones genetic potential). Within these two main dividing lines there are four distinct principles of social and political philosophy; libertarianism, socialism, communitarianism and liberal utilitarianism. All of these four doctrines can be democratic in their own special ways, but the content and principles of democracy varies considerably from one theory to another. (See LIBERTARIANISM; LIBERAL UTILITARIANISM; UTILITARIANISM; SOCIALISM; DEMOCRACY). (IP)
government program to provide long-term care for the elderly, disabled and mentally ill within the resources offered by the community, rather than in hospitals or institutions. The policy was first introduced in the UK and Australia in the early 1990s and represented a far-reaching National Health Service reform aimed at replacing traditional institutional provision of long-term care by community outreach programs. It was claimed that the major aim was to offer the long-term patient a better quality of life; however, the scheme has suffered considerable criticism on the grounds that, as old institutions closed, the level of support for people in need had correspondingly dropped placing a greater burden on non-professional carers, typically the children or partners of the disabled or elderly. (IP)
COMMUNITY SERVICES : Health care and related support services which are based in the local community . (DM)
COMPASSION: The emotion associated with sharing the suffering of another together with the desire to give aid. (See BENEFICENCE, CARING, LOVE, VIRTUES) (DM)
COMPENSATION : Payment for injury. (DM)
COMPETENCE : Mental capacity to make responsible choices. Compare to incompetence, which is used to refer to someone unable to make choices. (See INFORMED CONSENT). (DM)
COMPETITION: (Latin: competere 'to come together or seek in common') 1. Act of competing in the market, sport, examination etc. 2. In biology a process that determines how available resources are distributed among entities that demand them. The supply of any resource at the scale of biological organisms (including humans), is generally finite. Organisms that are best able to gather a resource amongst the efforts of other organisms to do the same, obtain more of this resource, and are said to be most competitive with respect to that resource. Indirect harm may be caused by the most competitive entity to any less competitive entities who receive less of the resource, especially if the resource is essential to their physical operation. One example of competition concerns plants regenerating in a place cleared of vegetation, but left for plants to regrow. Some plant species are very good at growing quickly, and they gain primary access to sunlight above slower-growing species, reducing the likelihood of their survival if they are unable to cope with reduced light. In this example, only a certain amount of light arrives at the surface of the earth, and this is the finite resource. The plants that are superior at acquiring light (by growing taller), do so at the expense of plants who are less competitive (slower growing). A related, and ethically relevant example is competition for space and other resources between humans and species of plants and animals. Humans are able to acquire vast areas of space (by habitat modification) at the expense of the organisms that occupied this space previously (unable to exist in the modified environment). Interestingly, some organisms might be better able to occupy the modified habitat, and they profit (e.g. establish larger populations) compared to their ability in the unmodified habitat. What, if anything, determines how much a particular organism should harm a competitor by reducing the amount they receive of an essential resource? Large bodies of empirical and theoretical research into aspects of competition exist in the ecological and economic literature. (See TRAGEDY OF THE COMMONS). (IP+HM)
COMPLACENCY : See APATHY.
COMPLEMENTARY DNA (cDNA):
DNA that is synthesized from a messenger RNA template; the single-strand form is often used as a probe in physical mapping. (DM)
COMPLEMENTARY MEDICINE: is a vast, heterogeneous set of therapies which generally have a common philosophy which is a belief in a holistic approach to health. Therapies focus, to varying degrees, on the integration of mind, body and spirit to restore health. Complementary medicine is also known as complementary and alternative medicine (CAM), natural therapies, alternative medicine, unconventional medicine and integrative medicine. Terms including "alternative" are now considered to be inappropriate as they imply a polarized position to that of allopathic or conventional medicine and is sometimes used in a pejorative sense to imply some form of quackery. A general definition is that complementary therapies are those therapies that are not taught as a normal part of medical education or provided within conventional health care facilities. However this becoming an increasingly impractical definition due to increased integration of complementary and conventional health care. In addition there is a culture context where therapies considered complementary in one culture may be mainstream in another e.g. acupuncture in China (JW).
1. Unpredictable, intricate, complicated or composed of many parts. (See COMPLEXITY) 2. Psychology: A group of related feelings, emotions or ideas which are activated, expressed, repressed and selected for together. (See MEME COMPLEX) (MP)
COMPLEXITY: Lack of predictability in a system due to nonlinear collective behavior. General order of complexity in the sciences, from the simplest or most predictable system mathematics, whose statements are logical consequences or tautologies, then increases through physics, chemistry, microbiology and biology, to greatest complexity in ecology and human sociology. A crude measure of complexity is the amount of information or symbols required for description. The emerging science of complexity theory tries to elucidate the universal features of complexity among systems. It uses synthesis as an opposing complement to reductionism, at the level of the behavior of subsystems and whole systems. (See COMPLEX, COMPLEXITY THEORY, SYSTEMS THEORY, EMERGENT PROPERTIES, SIMPLICITY, SIMPLEXITY, COMPLICITY, COMPLICATEDNESS, CHAOS) (MP)
COMPLEXITY THEORY: Complexity theory is the investiga nested hierarchies of subsystems, leading to coordinated behavior and emergent properties in meta-systems. C, chaos and order. Some of these trains of thought have a philosophical lineage in rational morphology and the search for laws of form (e.g. Kant,rt Kauffman,ARCHY, NETWORK, PROCESS) (MP)
COMPLICATEDNESS: Difficulty of analysis and understanding due to the presence of many interconnected elements. (See COMPLEXITY) (MP)
COMPLICITY: 1. Complicity is being in partnership; having an accomplice and sharing responsibility. 2. Complexity theorists Jack Cohen and Ian Stewart use complicity to mean the emergence of large-scale simplicity from the convergence of different subsystems of rules, which enlarges the space of the possible. Examples include evolution, consciousness, economics. Complicity is also referred to as super emergence (regular emergence is expressed in simplexity). (See SIMPLICITY, SIMPLEXITY, COMPLEXITY, EMERGENT PROPERTIES) (MP)
COMPONENTS: Units, parts, parameter, factors of a system, independent and interdependent units. Biotic components: genes, cells, organs, organisms, populations, communities. Abiotic components: Matter and energy (JA)
COMPROMISE: 1. Compromise is the process or result of concessions from both sides of a dispute with the aim of finding common middle ground. Settlement of differences is achieved from mutual adjustment of conflicting claims/principles by yielding a part of each. Compromise is possible for disputes but may be more difficult for institutionalized conflict. Cultural values or human needs such as identity and security may not be subject to compromise. 2. A concession made at the expense of ones integrity or original values; exposure to danger or suspicion, especially of repu to subject it to risk of passage to an unauthorized person. Compromise is from the original Latin: compromissum mutual promise to abide by a decision, now obsolete but appropriate to biohe previous positions. (See CONSENSUS, CONCILIATION, COLLABORATION, CONDITIONALITY, NEGOTIATION, FACILITATION, ARBITRATION, DISPUTE, CONFLICT) (IP & MP)
: Understanding by a patient or research subject of information disclosed orally or in writing. (DM)
COMPUTER : Any automated device or machine that can perform calculations on information or data. The data must be received in an appropriate form that is then processed according to specific instructions. The most widely used is the digital computer - an automatically controlled calculator machine in which data is represented by combinations of discrete electrical pulses. The information is analyzed according to a set of instructions or programs. At the same time as the computer's electronic circuits have decreased in size they have become smaller, faster and much more powerful. Fields such as science, technology, industry, commerce, education and communication could not cope in the modern world without the use of modern computers. (See COMPUTER MODELING). (IP)
COMPUTER MODELING : The development of a description or mathematical representation; i.e. a model, of a process or living system using a computer. This model can then be used to study the mechanism or behavior of the system under varying artificially controlled conditions, and analyzing likely outcomes. For example, the likely effect of a climatic change in areas where certain types of fauna and flora flourish maybe be amenable to modeling. To explore variables to an extent that is not possible by any other experimental means makes computer modeling a powerful tool in predicting possible ecological reactions under modern environmental stresses. (See COMPUTER). (IP)
COMPUTER VIRUS : An unauthorized computer program or software fragment which has the ability to propagate itself within a networked computer system or across the internet. It parasitizes other software, often damaging, deleting or otherwise interfering with data and/or the normal operations of programs. A 'virus' propagates itself by latching onto another program or data file. A 'worm' is able to self-propagate copies or segments of its programming autonomously. A 'Trojan horse' masquerades as a useful program whilst covertly accessing or altering restricted information. Computer viruses may be programmed by hackers, targeted at specific organizations by hacktivists, indiscriminately released by hacks, or strategically employed to jam data and communications during cyber-warfare. Viruses may arrive as executable e-mail attachments, and are often targeted at Microsoft products because of the widespread use of this software. Reproduction can be rapid and global, for example using e-mail address lists for propagation. This necessitates constant engineering of antivirus software, an interesting example of which is the 'viral predator' sent down the same electronic pathways in an attempt to hunt down and neutralize the virus and its progeny. (See WORM, BUG, VIRUS, ARTIFICIAL LIFE, HACKERS, HACKTIVISM) (MP)
COMPUTER WORM : See WORM.
CONCENTRATION CAMP : Internment centers for political prisoners. The British were the first to have instituted a system of concentration camps in Cap Colony and the Transvaal during the Boar War of 1901-1902. However, the most notorious concentration camp system was that used in Nazi Germany during the Second World War. Among the most infamous were Belsen, Buchenwald, Dachau, Auschwitz, Oranienburg, Papenburg, Maidenec and Treblinka. On account of their ethnicity, millions of innocent people were starved, tortured and killed in these camps as a deliberate act of mass extermination. (See INSTITUTION OF WAR, NAZI(S)). (IP)
CONCEPTION: The fertilization of the egg by a sperm that initiates the formation of a zygote (has been used for implantation also). (See FERTILIZATION) (DM)
CONCEPTUS: This term refers to the products of fertilization. It includes the embryo proper as well as extraembryonic structures and tissues that develop from the zygote (e.g. placenta). It is also called the preembryo . (DM)
CONCILIATION: Dispute resolution in normal relationships by the offer of friendly gestures and overtures. (See CONFLICT RESOLUTION) (MP)
CONCUBINE: archaic term for a class of woman who co-habits in the same house without being married to her partner. The famous orator of Greece Demosthenes (384-322 BC) placed things of Eros in perspective by defining " We have hetairas (prostitutes) for sensual pleasure, concubines for our daily bodily needs, and legal spouses to give birth to pure children and to be faithful guardians of the home ." In the majority of nations the legal rights of the de-facto partner or modern concubine approaches that of marriage (see marriage). (See MARRIAGE, OPEN MARRIAGE, ADULTERY) (IP)
CONDITIONALITY: 1. Depending upon certain conditions for a particular outcome. 2. A term pertinent to discussions of international development, often referring to the conditionality imposed upon structural adjustment loans issued by instor elementary school education in developing countries. (MP)
CONDOM: is a barrier method of contraception and protection from sexually-transmitted diseases (STDs) including AIDS. The term is derived from the Latin condus meaning receptacle and was originally designed as a prophylactic against STDs associated with prostitution. When properly used it ranks relatively high in effectiveness; however, its failure rate of between 10 and 15 percent, among the young especially, is often high (see FEMALE CONDOM). (IP)
CONFIDENCE LIMITS : Numbers that indicate the statistical certainty of a particular value. For example, if the 95% confidence limits for the mean mass (3.2 g) of a particular species of snail in a named wood are ±0.13 g it means that there is a 5% chance that the mean mass of that species of snail in that wood lies outside the range 3.07 to 3.33 g. (MR)
CONFIDENTIALITY: One of the important components of bioethical principles and a fundamental component in the physician-patient relationship, stemming primarily form the Hippocratic oath. All information of a person, whether personal, private or genetic is confidential and not to be revealed to others without the individual's consent. In the case of AIDS patients their visit to the testing place and results of testing should be held in confidence (DM, JA).
CONFLICT: A situation in which opposing viewpoints have come into physical confrontation. Conflicts are more intractable than simple disputes because of the existence of institutionalized, fundamental disagreement with limited malleability of participants or the situation. (See DISPUTE, CONFLICT RESOLUTION) (MP)
CONFLICT OF INTEREST
: Can arrive any time personal, family, national or financial interests distort the pure pursuit of truth, goodness, love or health. This can apply to anyone, for example a cab driver who takes you for a longer ride than necessary, or a member of the family of a terminally-ill mentally incompetent patient, who makes a "proxy" or "surrogate" decision to stop treatment, ostensibly for the patient's good but really to benefit from an inheritance, or because of the high cost of medical treatment (in those countries which do not yet have universal, government-supported, free health care), or because of the simple burden of care.
Bioethical attention, however, is usually given to conflicts of interest of scientists, scholars and health professionals. Cases are clear when a physician prescribes drugs manufactured by a company from which the physician benefits financially, or when a scientist publishes an article with positive conclusions about a drug or other product of a corporation for which the scientist works. Things are more complicated when a nurse hesitates to complain about medical negligence for fear of jeopardizing employment or advancement, or when a physician eats a free lunch supplied by a drug company for all who attend a staff lecture or grand rounds.
It is hard to be totally pure and free of conflict of interest. You may refuse to fly to a conference if the tickets are supplied by a corporation which you would like to be free to criticize, only to discover later that the disinterested scientific association which invited you received donations from that same corporation. And if you pay for the tickets from research funds which you receive from your own university, you might want to look into the corporations whose donations are allowing your university (and you and your family!) to survive. Nor does it help to say that everything is alright if you have academic freedom to say what you want. During the United States war in Vietnam, universities which existed on weapons research contracts were happy to employ radical anti-war professors, whose noisy presence gave the university a liberal image. Even if one could get free of financial interests, personal and emotional interests would remain. There is a school of literary criticism called "deconstructionism" which seeks the hidden motives of authors of literary creations. Ideas from this school have had some influence on philosophical and scientific criticism. Medical journals are beginning to require that authors list possible conflicts of interest. (FL)
CONFLICT RESOLUTION: Conflict resolution is an important feature of both personal and international relations. Conflict analysis, negotiation, mediation, conciliation, facilitation, arbitration and judicial settlement are aspects of collaboration towards a compromise or consensus decision. Negotiation can be aided by good working relationships, persuasive value systems and soft power. Mediationtion provt, whereasTION, COMPROMISE, CONSENSUS, CONCILIATION, PREVENTIVE DIPLOMACY, PEACE BUILDING, PEACE MAKING, PEACE KEEPING) (MP)
Confucius (c.551-479 bce) Philosopher of ancient China. The teachings of Confucius were recorded by his students, especially in the book known as Lun Yu (or in English: Analects). Confucius stressed the importance of acquiring virtue and acting according to proper moral behavior. His teaching places special emphasis on the importance of family, and on filial obligations towards parents. The father-son relationships is one of the Five Relationships (see Five Relationships). Confucius' teachings were influential not only in China, but also in Japan, Korea, Vietnam and other parts of East Asia. (AG)
CONFUCIAN CANON: Chinese texts of Confucianism containing the philosophy of Confucius, or K'ung Fu-tzu (551-479 BCE ), originally comprising the Five Classics ("Shih Ching", "Li Ching", "Shu Ching", "Chun Chiu" and "I Ching"), later reorganised by Chu Hsi (1130-1200 CE ) into four Books ("Analects of Confucius", "Book of Mencius", "Great Learning" and "Doctrine of the Mean"). (See CONFUCIUS) (MP)
CONGENITAL DISORDER : A defect present at birth, regardless of cause, which may or may not be inherited. (JA, DM)
CONGENITAL MALFORMATION structural or anatomical aberrations or less obvious physiological, functional, immunological or behavioral defects in neonatal or postnatal offspring (see teratogen). (DM+DR)
The coniferous, or boreal foresrous forest, or taiga, con forests provide important habitat for hawk, owl, mink, elk, moose, bears and wolf. (See TAIGA, GYMNOSPERM, SOFTWOOD) (MP)
CONJECTURE: Conjecture simply means taking a guess. For example, a hypothesis is a refined and structured kind of conjecture. An educated guess is made by an expert with some backing in related knowledge. Heuristics is the use of educated guesses in the search for a solution. (See HYPOTHESIS, HEURISTICS, ASSUMPTION) (MP)
Two fetuses developed from the same ovum that are physically united at birth. Conjoint twins are the result of identical twins where the split is incomplete and the two new embryonic axes fail to separate in their entirety. The degree of union may be slight or extensive, and the twins may be joined at any part of their bodies. Most conjoined twins do not survive after birth and frequently suffer from major heart malformations. Ever since medical science made the separation of conjoined twins a possibility, there have been concerns about the ethics involved; sometimes one of the twins is sacrificed for the sake of the other. The famous 'Siamese' twins, Eng and Chang Bunker, were born in 1811, lived for 63 years and had 22 children between them. Their wives lived in separate houses and the twins spent alternate weeks with each of them. (See TWINS/TWINNING). (IP)
CONJUGATION: The reproductive process by which DNA is transferred between bacteria during cell-to-cell contact. (DM)
CONSANGUINITY: Descent from common ancestors. (DM)
CONSCIENCE: The ethical sense of right and wrong which is generally valued as the hallmark of a true existence as it represents the ability to choose and decide to take action and assess reaction. What one believes is right or wrong. It is sometimes thought of as an "inner voice". The conscience is a very unreliable guide to ethics. Psychopathic killers have sometimes thought that their consciences were telling them to kill. (IP, FL)
CONSCIENTIOUS OBJECTOR : A term that came into prominence during the First World War and applies to those who object to military service in a fighting capacity on moral, religious or ethical grounds. The British Military Service Act of 1916 dealt with conscientious objectors characteristically harshly. In 1939 provisions were made in the Military Training Act for exemption of bona fides to be allocated to various other appropriate form of national service. (See VIETNAM WAR, INSTITUTION OF WAR). (IP)
CONSCIOUSNESS: The registration of an effect, for example, a scale is conscious of weight. The ability to be aware of one's actions or experiences. Most biologists would hold that at least many mammals species, including the non-human primates, exhibit consciousness. Moral agents have especial duties towards conscious entities since such entities are aware of their pleasures and PAINS (q.v.). It is difficult to suppose that there will never be conscious ROBOTS (q.v.). (MR)
CONSEQUENT : In logic the second part of a conditional statement; that is, a statement (or proposition) that is said to follow from, or be implied by, another statement. For example, if the breeding conditions improve then the endangered species will flourish - will flourish is the consequent. (See CONSEQUENTIALISM). (IP)
CONSEQUENTIALISM: The normative theory that the rightness or wrongness of actions is determined by anticipated or known consequences, compare to deontologism. (DM)
CONSENSUS: A consensual agreement or win-win outcome of collaborative problem-solving and conflict resolution. A consensus implies that debate has taken place, the solution is generally accepted rather than a grudging compromise, and that agreement is deep-rooted enough that it can stand for some time without need to revisit the issue. (See COMPROMISE, COLLABORATION, CONFLICT RESOLUTION, DELPHI METHOD) (MP)
: A conference of persons, usually of lay persons, which seeks to reach consensus on a moral dilemma, which is useful as a model for society. (DM)
CONSENT: See INFORMED CONSENT.
CONSENT FORMS : Papers given to persons to explain a procedure, and request their signature as a record of agreement. (See INFORMED CONSENT, CLINICAL TRIALS). (DM)
CONSERVATION: includes both preservation and protection, preservation for long term use by the future generation and protection of what we have on the biosphere (earth). Opposite of hoarding. Needs sound management practices. Two types - In situ and Ex situ depending on the region of conservation. see In situ and Ex situ. In situ Conservation: - conservation of naturally found ecosystems includes the care and maintenance of living populations of species in their natural habitats - domesticated and cultivated species. Ex situ Conservation: - When an exotic species is removed from its original habitat and in an artificial habitat such as the zoo/zoological parks and botanical gardens/seed banks. Currently there are about 500.000 species of living creatures in zoos and 35,000 species of plants in 1,500 botanical gardens which is 15 per cent of world's plant resources. Some estimates indicate the number of plant species in botanical gardens as high as 70,000 to 80,000 species. Example - Royal Botanic Gardens at Kew, UK (JA)
CONSERVATION DEPENDENT SPECIES: A species which is the focus of a continuing program of taxon or habitat conservation, such that it would qualify for threatened species status if the conservation efforts were to cease. (See CONSERVATION, THREATENED SPECIES, ENDANGERED SPECIES) (MP)
CONSERVATION OF BIODIVERSITY: See CONVENTION OF BIOLOGICAL DIVERSITY.
CONSERVATION OF CULTURE: See CULTURAL HERITAGE, CULTURAL EVOLUTION.
CONSERVATION OF HERITAGE: See HERITAGE.
CONSERVATION MOVEMENT : Widespread belief, accompanied by action, that wildlife and wilderness areas should be preserved. Many traditional cultures have an implicit conservation movement, though traditional cultures have also often caused environmental degradation and have resulted in species going extinct. In the West the modern conservation movement dates only from the late nineteenth and early twentieth century when increasing numbers of people became concerned at the threat to rare species, scarce habitats and unspoilt areas of natural beauty. An increasing number of non-government organisations have arisen dedicated to conserving certain aspects of the natural world. (See GREEN MOVEMENT). (MR)
: The joining together of knowledge and information across disciplines to create a unified framework of understanding. The concept was developed by Harvard biologist E.O. Wilson in a book named
Consilience: the unity of knowledge
(1997). (See E.O. WILSON, HOLISTIC THINKING) (RW)
CONSPICUOUS CONSUMPTION: The consumption of goods based on the desire for social status, such that the satisfaction is based upon the desire to impress rather than on any other usefulness or utility of the item to the consumer. (See CONSUMPTION, CHINDOGU) (MP)
CONSTANT CAPITAL: The constant capital rule implies the passing on to future generations of an aggregate capital (economic, human and natural capital) equivalent to that of today. Strong sustainability requires the forms of capital to remain in constant proportion, whereas weak sustainability allows substitution between them. Critical natural capital must remain constant, functioning as it does to provide our global life-support system. (See STRONG SUSTAINABILITY, WEAK SUSTAINABILITY, NATURAL CAPITAL, CRITICAL NATURAL CAPITAL) (MP)
See SCIENTIFIC METHOD.
CONSUMER PARTICIPATION : See PUBLIC PARTICIPATION.
CONSUMPTION: Resource consumption is the utilization of natural capital, involving flows of energy and materials from the environment. Consumption creates the demand which is the economic driving force for production and supply. Personal consumption may be measured per capita in dollars, energy use, tonnes of CO2 emissions, paper consumption, water usage, or ecological footprint. Consumption is one of the major socioeconomic factors leading to environmental destruction. It is a central component of Ehrlichs famous equation I=PCT (in which I = ecological impact, P = population, C = consumption, and T = thasis on materialistic economic measures of wellbeing. Reality however reminds us that global limitforms of consumption have environmental costs significantly disproportional to any real human benefcuous consumption are phased out or become socially unacceptable.

CONTACT TRACING : A public health practice of identifying persons who have been exposed to a communicable disease through person-to-person contact; includes, for example, identification of the sexual partners of persons infected with the human immunodeficiency virus. (See AIDS, CONFIDENTIALITY , COMMUNICABLE DISEASES, PUBLIC HEALTH). (DM)
CONTAINMENT : The use of biological or physical means to minimize or prevent the dissemination of biologically active agents which may be hazardous. (See BIOSAFETY, RECOMBINANT DNA RESEARCH). (DM)
1. Important initial reference list of the structure, organization and themes within a work of (usually) non-fiction. (See INDEX) 2. Inside elements; ingredients determined by the reductionist approach of breaking something down into its constituent parts. (See CONTEXT) (MP)

CONTIGS: Groups of clones representing overlapping, or contiguous, regions of a genome. (DM)
CONTINUUM: A plane of thought; a continuous axis or tangent. In mathematics the continuum is the set of all real numbers. Elements or opinions are arranged in clumps along many conceptual continuums. Opposites are at polar extremes of a continuum, but often cannot really exist without the other. The continuum reminds us that ideas have fuzzy boundaries, and that most things are not black-and-white but a matter of degree. (See SPACE-TIME CONTINUUM, FUZZY LOGIC, MIDDLE WAY) (MP)
the prevention of pregnancy, especially through the use of devices and medications, or through behavioral procedures such as withdrawal, abstinence, and sterilization. Contraception by biological means involves the prevention of one or more of a) formation or release of gametes in the male or the female b) fertilization c) implantation of the fertilized egg, or development of the early embryo [Latin

CONTRACEPTIVES: devices or medications used to prevent conception. These include diaphragms, condoms, intrauterine devices (IUDs), cervical caps, spermicidal creams, various formulations of the pill, subdermal implants and injectables (see Contraception). (IP)
CONTRACT: Binding agreement between two or more parties. Most ethicists would hold that a person generally has a duty to fulfil a contract into which she has voluntarily entered unless certain unforeseen and particular circumstances arise so that significant harm would result from fulfilling the contract.
A social contract, is, roughly speaking, a presumed, implicit agreement between the members of a SOCIETY (q.v.) or between individuals and the state. Thus, for example, there may exist an unspoken agreement that the state should uphold the rule of law so that I and other good citizens may live in peace but that, at the same time, I have certain duties towards the state - for example, to sit on a jury or even fight on its behalf in a (just) WAR (q.v.). (MR)
CONTRACTARIANISM: Ethical and political theories involving a social contract. Negotiations are capable of yielding mutual principles of conduct, which are binding upon all parties to create a just society. Ethical philosophers who had an influence on contractarian thought include Hobbes" moral theory based on desire, and Kants "Metaphysics of Morals" (1797). The most famous contemporary contractarian is John Rawls, who in his "A Theo of individual equality. Other contractarians may define the goals or contracting parties in different ways, fthe most good for the greatest number. (MP & IP)

CONVENTION OF BIOLOGICAL DIVERSITY (CBD) It was negotiated before the United Nations Conference on Environment and Development held in Rio de Janeiro in 1992. The agreed text of the convention of biological diversity was adopted by 101 governments and signed by 159 governments and the European Union. It was adopted to stress the equity in the use of biodiversity on ethical principles. CBD has been ratified by a total of 177 countries, excluding the United States of America. The objectives of the Convention as stated, in part, are as follows: Article 1 "conservation of biological diversity, the sustainable use of its components and the fair and equitable sharing of benefits arising out of the utilization of genetic resources, including by appropriate access to genetic resources and by appropriate transfer of relevant technologies". Article 2 " Biological Diversity means the variability among living organisms from all sources, including, inter alia, terrestrial, marine and other aquatic ecosystems and the ecological complexes of which they are part; this includes diversity within species, between species and of ecosystems". (IP, JA)
CONVENTIONAL WEAPONS: Euphemistic term for missiles, explosives, artillery, small arms and other weapons, which although distinct from nuclear or other weapons of mass destruction, have in total produced ovance, Russia, China and North Korea who have been among major world-wide distributors of conventional weapons. The boundaries of conventional should not be pushed to include decidedly unconventional new proposals such as space weapons, low-impact nuclear weapons (e.g. gamma ray bomb) or swarm intelligence.

Coral is a colonial animal which is formed from the symbiotic relationship of single-celled dinoflagellate algae (zooxanthellae) with coral polyps (class Anthozoa, phylum Cnidaria). The polyps exchange phosphates and nitrates for carbohydrates in the process of skeleton building. (See CNIDARIA, CORAL REEF, CORAL BLEACHING) (MP)
CORAL BLEACHING: A devastating condition which has spread alarmingly in recent years and now affects large regions of Earths coral reef systems, coral bleaching occurs when the zooxanthellae evacuate the coral skeleton, leaving thting global warming as a possible cause. Coral bleaching is a process which destroys the very habitat upon which whole ecologies depend. (See CORAL) (MP)
CORAL REEF: A habitat which provides for one of the largest biodiversities of any other, coral reefs are perhaps the underwater equivalent of tropical rainforests. Also found mostly in tropical and subtropical zones, coral reefs tend to form in less than 100m depth and greater than 18 o C temperature. An atoll is a coral island, often a ring of reef with a lagoon. Coral reefs are dynamic systems with high biodiversity, productivity and complexity, even in a nutrient-poor environment. They are giant living platforms of interlaced corals and the complex ecological community that comes along with them. Coral reefs are fragile, and currently threatened by coral bleaching, sediment/fertilizer runoff, commercial fishing trawlers, over-fishing, oil exploration, pest species like the crown-of-thorns starfish, anchor damage, development and mass tourism. (See CORAL, CORAL BLEACHING, GREAT BARRIER REEF, SUPER-ORGANISM) (MP)

CORONAS meaning "crown" are colored rings which appear around the moon or sun when seen through thin clouds consisting of water droplets. They are produced by diffraction and are more common with the moon because the suns brightness may make it difficult to see the effect (see RAINBOWS, HALOES, MIRAGES & GREEN FLASH). (IP)
CORRELATION: Relationship between two variables. A correlation coefficient shows how closely two sets of data are related. If the relationship between the two sets of data is perfect and positive, then the correlation coefficient is 1.0. If, for example, an extra 1 cm of height always meant that a person was 600 g heavier, then the correlation coefficient between heights and masses among people would be 1.0. If the relationship between two sets of data is inverse, then the correlation coefficient is negative. A perfect, inverse relationship has a correlation coefficient of -1.0. When there is no relationship between two sets of data the correlation coefficient is close to 0 and does not differ significantly from it. Correlation does not imply CAUSATION (q.v.). (MR) (See CAUSATION)
A hypothesis is corroborated if it is subjected to an experimental test which cannot manage to falsify it. (See FALSIFICATION) (MP)
CORROBOREE It is said that the word is the English version of the Australian Aboriginal
term "carib-berie" or ceremony ritualized in song and dance. Traditionally, corroborrees re-enacted the Dreamtime or Creation stories and were also activated for sacred, law education or war-like purposes. Aboriginal cultures have an oral tradition where stories (often past from one generation to the next for thousands of years) are used to educate about traditional law, folk lore, spirituality and gender-specific matters (see Menss Business & Womens Business). Nowadtheir perspective (see AUSTRALIAN ABORIGINAL). 2. In general usage for any large and noisy Australian celebration. (IP)
A glucocorticoid steroid hormone produced naturally by the cortex of the adrenal gland and also synthesized for pharmacological use. Cortisol and its synthetic derivatives; such as cortisone (also called prednilosone), are most potent anti-inflammatory agents that can effectively treat asthma attacks and reduce joint inflammation. When injected directly into joints, bursae or tendon sheaths the drug, since it does not enter the general circulation, is less likely to cause multiple toxic effects compared to oral administration. Treatments for asthma, which are typically delivered in aerosols (puffers or inhalers) containing corticosteroids such as cortisone, are drugs that relax (bronchodilate) airways. Asthma is more common in Australia and New Zealand than anywhere else in the world. It is thought to be provoked by external allergens such as pollen, dust, certain foods, emotional crises and excessive cold or exercise. (See ADRENAL GLANDS; ASPIRIN). (IP)
COSMETIC SURGERY : (Greek kosmesis 'adornment'). The improvement of the outward appearance of parts of the body. A distinction can be made between cosmetic surgery and plastic surgery where the former, typically, refers to minor reconstruction of cutaneous or underlying tissues performed to improve or correct a structural defect. This is usually done under local anesthetic. Plastic (from the Greek plassein 'to mold') surgery, on the other hand, applies to the alteration, replacement or restoration of visible parts of the body in order to correct a major structural or cosmetic defect. In these operations the surgeon may, typically, resort to tissue grafting (most commonly skin grafts) or employ inert material that can be molded into the required shape (mammoplasty or breast implants, for example). Reconstructive plastic surgery is routinely performed to correct birth defects (cleft lip and palate, for example) and to repair structures destroyed by trauma. (See COSMETICS). (DM, IP)
COSMETICS : (Greek kosmein 'to adorn'). The preparations used to enhance the appearance of skin or for emphasizing the features of the face or the shape of the finger-tips and so on. Face powder made of powdered rice or semolina, or of chemical compounds has been widely used for giving the face a smooth, mat surface. Kohl is used for shading the eyelids in order to make the eyes appear bigger, henna for staining hair, fingers and toes. Rouge for coloring cheeks and rouge paste (lipstick) for reddening the lips and varnish for finger and toenails. Since antiquity, the human animal has re-designed the body to enhance beauty for aesthetic augmentation and for heightened sexual excitement. (See COSMETIC SURGERY). (IP)
COSMIC RADIATION : High-energy particles with extreme penetration power capable of passing through many meters of lead. Cosmic rays originate in outer space and are distinguished as primary which impinge on the Earth's atmosphere and secondary which are produced within the atmosphere, or the Earth itself, from collisions between the primary radiation and atmospheric atoms.

CREATION: see CREATIONISM; ORIGIN OF LIFE.
CREATIONISM: The idea that God created the world, sometimes also identified with the idea that God created each species separately. Some people think that creationism conflicts with the idea that the world has always existed, but there is no contradiction in the idea that a God who has always existed has always been creating the world. Some people think that Darwinist evolutionary theory conflicts with creationism, but there is no contradiction in the idea that God created the world with laws of the sort described in Darwinist evolutionary theory. (See ORIGIN OF LIFE).
Fundamental Christian creationists have often objected to Darwin, just as the Catholic Church condemned Galileo for his acceptance of the Copernican heliocentric theory in astronomy. This was because Christians often insisted on a literal interpretation Of the Bible. But Jews, who since Talmudic times have been accustomed to metaphorical interpretations of Biblical texts, had no theological problems either with Galileo or Darwin. Darwin reported that an article in Hebrew claimed that the doctrine of The Origin of Species matches the Biblical account of creation. Rabbi Avraham Itzhak Kook, the great rabbi and philosopher of modern Israel, had a philosophy very congenial to Darwinism. (See ORIGIN OF LIFE) (FL)
CREATIVITY: Valid originality. (MR)
CREEL SURVEY: A creel is a basket or trap for holding fish, so a creel survey is a technique for estimating fishing effort by interviewing fishers and surveying their catch. (See SUSTAINABLE FISHING) (MP)
Burning of the human body and reducing it to ashes. This practice was in effect in Europe already in the Stone Age. In Mycenean Greece (10 century bce), it was an important part of Greek funeral ceremonies. Cremation was widely practiced in the Roman Empire, but was avoided by the Jewish and Christian communities, because the practice was seen as pagan. It was also avoided by Zoroastrians because it was seen as polluting the fire. (see Tower of Silence) In Asia, cremation is an important part of Hindu and Buddhist funerals, and has been practiced since ancient times. (AG)
CREUTZFELDT-JAKOB DISEASE (CJD) a fatal encephalopathy caused by a prion first documented by German neurologists Hans Creutzfeldt (1885-1964) and Alfons Jakob (1884-1931). The formation of dementia-inducing plaques in the brain of infected individuals causes a progressive decline in cognition and motor function and, ultimately, death within a year of commencement of symptoms. The prion is thought to be a human variant of mad cow disease. There are well documented cases of cross-infection in patients who have developed the disease iatrogenically following corneal transplantation or hormonal treatments, such as fertility drugs or growth hormone, processed from infected human pituitary-derived preparations. The true extent of spread in the human population is unknown because of the diseases extended 15-40 year incubation period (see PRIONS & BOVINE SPONGIFORM ENCEPHALOPATHY). (IP)
CRIMES AGAINST HUMANITY: A term used since the Nuremberg Trials, international war crimes recognized as 'Crimes Against Humanity' (Rome Statute of the International Criminal Court, 1998) are known acts as part of widespread or systematic aggression towards any civilian population which include: a) murder, b) extermination, c) enslavement, d) deportation or forcible transfer, e) imprisonment, f) torture, g) rape or enforced prostitution, pregnancy or sterilization, h) group persecution on grounds of politics, race, nationality, ethnicity, culture, religion or gender, i) enforced disappearance, j) the crime of apartheid, and k) other similarly inhumane acts causing great suffering or serious mental or physical injury.

CRITICAL NATURAL CAPITAL:
Natural capital and environmental assets essential to the functioning of the life support services supplied by ecosystems. These non-substitutable components of the global environment must be conserved for human survival and wellbeing. Human uses and values are ultimately dependent upon the primary values of ecological systems. Biogeochemical cycles, keystone species and the ozone layer are examples of critical natural capital. (See NATURAL CAPITAL) (MP)
CRITICALLY ENDANGERED: A species or other taxon which is at extreme risk of becoming extinct in the wild in the immediate future. This may be indicated by any of the following measures: a) a previous or projected population reduction of at least 80% over whichever is longer of a period of 10 years or three generations, b) extent of occurrence less than 100 km 2 or area of occupancy less than 10 km 2 , along with population decline, fragmentation or extreme fluctuations, c) population less than 250 mature individuals with continuing decline, d) population less than 50 mature individuals, or e) probability of extinction in the wild estimated at 50% over the longer of 10 years or three generations.

CRYOBIOLOGY: (Greek: kryos 'cold') Refers to the technology of freezing and thawing of biological tissues, particularly of gametes (sperm and oocytes) and embryos. Although the deep freezing of sperm was developed early in the 1900s, the successful freezing and thawing of oocytes and embryos is a relatively new technology. The first successful freezing and thawing of mouse embryos was reported independently in 1972 by David Whittingham and Ian Wilmut and paved the way for the first human frozen embryo born in 1983 in The Netherlands, and the second in Australia in 1984. (Greek kryos cold) (see CRYOPRESERVATION). (IP)
CRYOGEN: (Greek: kryos 'cold' + genein 'to produce') A chemical such as dry ice (solid carbon dioxide) that induces freezing which is commonly used to destroy diseased tissue without injuring the adjacent structures as used in cryosurgery (Greek kryos hidden + genein to produce) (see CRYOBIOLOGY AND CRYOPRESERVATION). (IP)
CRYOGENICS: The science of producing very low temperatures, as well as the applications, phenomena and technology pertaining to those temperatures. Applications include cryobiology, cryosurgery and the cryopreservation of biological samples.

CRYOPRESERVATION: A hi-tech methodology involving the use of liquid nitrogen to preserve living organisms/parts (sperms/eggs/embryo) with a possibility of revival to life at a later date. A method of preserving cells, tissues and organs in a viable state by freezing. The basis of the technique is to allow cooling to take place at a carefully controlled rate in the presence of cryoprotective agents; that is, antifreezes such as dimethylsulphoxide with the aim to subject, an embryo for example, to controlled desiccation thus preventing fatal damage by the formation of ice crystals. Once deep-frozen the gametes/embryos may be stored indefinitely in liquid nitrogen at a temperature of minus 196 degrees Celsius . Cryopreservation is particularly important in the context of the preservation of endangered species (see CRYOBIOLOGY). (IP+JA)

CULTIVAR: An international term denoting certain cultivated plants that are clearly distinguishable from others by one or more characteristics and which when reproduced retain those characteristics. A cultured variety of plant. In the USA "variety" is considered to be synonymous with cultivar (derived from cultivated variety). Cultivars are also called ^straqin^. In closely related species although a few genetically disctiinct features can be recognized, the differences are not strong enough to consider them as two different species. This word is commonly used in plant breeding and in the culture of microorganisms. (DM, JA).
CULTURAL EVOLUTION: Culture evolves and technology progresses, with cultural evolutionary mechanisms analogous but different to those of biological evolution. Investigators of evolutionary aspects of culture have included philosophers (e.g. Lewis Morgan, Arnold Toynbee, James Baldwin, Thomas Kuhn, Daniel Dennett, Jared Diamond), social Darwinists (Herbert Spencer), linguists (Noam Chomsky, Steven Pinker), environmentalists (E.F. Schumacher), biologists (Richard Dawkins), sociobiologists (F.T. Cloak, E.O. Wilson) and technologists (Eric Drexler, Marvin Minsky). Cultural evolution differs from biological evolution in its fast rate, directedness, and Lamarckian copy the product inheritance amoete for survivalion, globalization, westernization and urbanization.

CULTURAL HERITAGE: Cultural heritage sites include the significant monuments, architecture, artistry, archaeology, artifacts and other human works of outstanding universal value from the point of view of history, art or science. The conservation of cultural heritage is achieved at a local level with organizations such as the National Trust of Australia, and internationally as outlined in the 1972 UNESCO Convention concerning the Protection of World Cultural and Natural Heritage. The less tangible forms of cultural heritage - beliefs and practices handed down by generational transmission, must be conserved by recording indigenous knowledge into permanent written form, and by maintaining cultural diversity itself. (See HERITAGE, NATURAL HERITAGE, WORLD HERITAGE) (MP)
The cultural background and behavioral distinctiveness an individual tends to be associated and identify with. Cultural identity is a mixture of history, social mores, cultural values and spiritual belief. Using the Australian example, Aboriginal culture may identify with life on the land, local community, respect for elders, and the ancestral Dreamtime. Members of the stolen generation adopted into whi egalitarianism, TURE, MULTICULTURALISM, MINORITY GROUP, BOAT PEOPLE, STOLEN GENERATION) (MP)
CULTURAL IDENTITY : Cultural identity is a form of collective identity which is focusing on culture. Whereas in a nation state, most of the citizens are having a sense of belonging (collective identity) resulting from a shared faith as a people, a common central government, constitutioal rights and some basic societal values, they can have various cultural identities (for instance, as Native Americans, African Americans, Irish Americans, and so on). (BP)
: The presence of multiple value systems within or among societies.(DM)
CULTURAL RELATIVISM : The idea that there are no absolute rights or wrongs, but what is right and wrong depends upon what is accepted in one's culture. It would follow from this doctrine that female infanticide is perfectly alright, just so long as one's culture accepts it. (FL)
CULTURE [Social meaning] : The way people live in identified areas, times and settings (HT. Odum)* sum total of cumulative processes and products of societal achievement. Includes: Folk - Customary attitudes and social norms and customs believed and practiced traditionally, e.g. Eastern practice of eating with hands; Technological - changes in customary attitudes and social customs due to advances in science and technology, e.g. Eastern practice of eating with fork and spoon.
Cultural lag: both folk and technological cultures do not keep pace with each other, a term proposed by F. Ogburn in 1922 to indicate the difference between the two. Education and regulatory norms/practices are necessary to bridge the gap. (JA)
CULTURE [Scientific meaning] : technique of growing cells/tissues/plants/microorganisms in sterilized liquid/agar gel media containing nutrients. Tissue culture - growth of plant/animal tissue in liquid medium, first practiced by the German botanist Gottleib Haberlandt during 1902. Meristem : Extension of plant tissue culture, in liquid culture medium containing auxin and cytokinin, produces many new shoots from a single plant shoot apex. Anther : a recent technique, mature anthers are grown in tissue culture medium with vitamins and plant growth regulators, in dividing haploid pollen tube cells yields proembryos, with the rupture of pollen grain about 40 haploid embryos are released. (JA)
CULTURE : Everyone has a culture because culture is about people, how they live and interact with one another. There is also no indigenous culture without its spiritual traditions, social practices, beliefs and laws of behavior - whether it be the rite of passage into adulthood involving greater responsibility, or initiation rituals conferring the status of "wise elder" commanding a deeper service to the community. For our hunter-gatherer ancestors, the only means of passing on knowledge was by example, demonstration or word of mouth, and elders of a tribe were given special status as an acknowledgment of knowledge and experience. The Australian Aboriginal culture, for example, is contained within the Dreaming stories (see DREAMTIME and DREAMING). (IP)
CULTURE JAMMING: Strategic media manipulation and the re-application of advertising techniques and mass-media channels for activist, subversive or culturally reflective purposes. Culture jamming is social activism in the information age. Culture-jammers see themselves as communication strategists supplying sensitive information suppressed by mainstream media, spreading memes or media viruses towards the emergence of an alternative paradigm. Early examples might include Australias BUGA-UP graffiti network, Americas Hip-Hop culture, communi media channels with alterom mild political satire t Culture jammers are true mature strategy, direct criticism, defamation or any obvious confrontation which may provide impetus to counter-actions.

CURIE : Unit of radioactivity defined as the quantity of any radioactive nuclide which undergoes 3.7x10 10 disintegrations per second. (See RADIOACTIVITY; RADIATION; CURIE, MARIE; CURIE, PIERRE). (IP)
CURIE, MARIE : (1867-1934). Polish-French physicist, chemist. Co-discoverer with Pierre Curie of radium and polonium. Mari Curie was the first woman to win a Nobel Prize in 1903 for physics jointly with her husband Pierre and Antoine Becquerel (discoverer of radioactivity in uranium) for their work on radioactivity; and the first person to win a second Nobel Prize in 1911 in chemistry for her discovery of radium and polonium. In her pursuit to demonstrate that two uranium minerals - pitchblende and chalcolite - were more radioactive than uranium, she discovered the existence of two new highly radioactive elements, radium and polonium. At the time the harmful effects of radiation were not recognized, thus, no precautions were taken and it has been said that Marie's notebooks of this period are still too dangerous to handle. However, a quote from the preface of Pierre Curie's 'Collected Works' may give the reader a flavor of the excitement that cutting-edge research may bestow 'I remember the delight we experienced when we happened to enter our domain at night and saw on all sides the palely luminescent silhouette of the products of our work. ' Marie Curie's major published work was the two-volume 'Treatise on Radioactivity' (1910). Marie Curie died of leukemia. (See RADIOACTIVITY, RADIATION, CURIE; CURIE, PIERRE). (IP)
CURIE, PIERRE : (1859-1906). French physicist. With Marie Curie he subjected pitchblende (a uranium ore) to fractionation hoping to reveal a substance more radioactive than uranium. This research resulted in the discovery of radium and one of its transformations products polonium. In 1903 the Curies received the Nobel Prize for physics, it being shared with Antoine Becquerel who, in 1896, discovered radioactivity in uranium (Becquerel rays). Pierre Curie tragically died in a street accident. (See RADIOACTIVITY, RADIATION, CURIE; CURIE, MARIE). (IP)

CYBER CRIME: Crimes committed primarily through Internet contact include: credit card fraud, identity theft, child pornography, indecent chat-room behavior, software and media piracy, web-site vandalism, release of viruses and worms, spam marketing, invasion of privacy, cyber-spying and most forms of hacking and cyber warfare. The cyberian legal system has a hard job keeping up along the technology trail of software designers and hackers. (See HACKER, INTERNET PRIVACY, MEDIA PIRACY, CYBER WARFARE) (MP)
The civilization developing in the online world of cyberspace. To some extent cyberia parallels and interacts with outside social reality, containing structures for business, education and entertainment. Its limitations are however not the physical environment and political authority, but the rather the capacities of technology and human imagination itself. The future nature of cyberia will be engineered by cyberians themselves. Increased computer power and improvements in virtual reality technology will make it a much grander and easier empire for many to spend larger amounts of time. Cyberian social organization has both democratic and anarchic elements. Its unruly networks include temporary autonomous zones and encrypted communities able to act as independent informational and political structures, whether they be cultural expressions, terrorist networks or sanctioned military science. (See CYBERSPACE, CYBERCULTURE, VIRTUAL REALITY) (MP)
CYBERCULTURE: The culture developing around computer technologies and within the cyberspace environment. Cyberculture is often characterized as a reflection of a fractured technocentric existence; individualistic, egalitarian, anti-authority, technologically enabled, chemically enhanced, postmodern, multimodal and multidimensional. The inhabitants of cyberia tend to be young and/or professional, sometimes internet addicts, activist hackers, pioneering cybernauts and nerd geniuses whose life revolves around access to information and technology.

CYBERNETICS: (Greek: kubernetes "steersman" or "self-regulation") The branch of science concerned with communication and control systems in organisms and machines, and the common ground between biology and computation. Cybernetics incorporates the concepts of feedback, homeostasis and neural networks. A cybernetic system involves a series of operations in which information gained at one stage can be fed back to modify later stages of the process. Such feedback allows control systems to check and adjust behavior as required. For example, the bodys response to stress functions as a biological cybernetic system in which biofeedback from its subsystems act as a mastecs" was coined and developed by US mathematician Norbert Wiener (1894-1964), in his 1948 book of the same name.

CYBERPUNK: The genre of science fiction dealing with cyberspace environments and social organization within the virtual worlds of integrated computer networks. Cyberpunk is characterized by dystopian visions of a bleak technocentric future and anarchic cyberian societies, the darker electronic by-ways of which are frequented by techno-enhanced freaks and rebellious hackers. The genre reflects the visions and fears of the young, and addresses bioethical issues of control and autonomy in a future of irreversible integration of technology into human bodies and minds. (See CYBERIA, SCIENCE FICTION, DYSTOPIA) (MP)
CYBERSEX: The most significant proportion of web traffic consists of pornography and other sex-related content. Anonymity and interactivity has made cyberspace a haven for those interested in sex, whether it be finding a partner through chat rooms, cyber sexual harassment, or explicit pornographic material. If the internet is any guide, the development of virtual reality technology may also be driven by the sex industry. Teledildonics is a term used in virtual reality discourse which describes simulated sexual intercourse in cyberspace. This online sex may be with a designed artificial partner, or sex at a distance with a real person, making use of tactile clothing, sensory equipment and real-time interactive telepresence. (See VIRTUAL REALITY). (MP)
CYBERSPACE: A term apparently first defined in William Gibsons Neuromancer as "consensual hallucination", cyberspace is the hyperdimensional environment of the internet, virtual reality and the online experience. This digital turf is generated by integrated information networks and computer technology, but has the feel of a real but radical universe with its own laws, for example allowing dissociation from the body and identity. Cyberspace enables interpersonal exchanges without the limitations of time, place or race, through e-mail, videophone links, virtual conferences, translation software, voice recognition, multimedia, digital viruses, artificial environments, and even interactive touch and smell with recent virtual reality technology. It is a place characterized by freedom, vibrancy, individuality, intrusiveness, incongruent conjunctions of people and ideas and complex flows of information. Cyberspace is an artificial space divorced from biology and the surrounding environment but unlimited in its internal complexity. (See INTERNET, CYBERIA, CYBERCULTURE, CYBERWARFARE, WORLD WIDE WEB) (MP)
See INTERNET PRIVACY.
CYBERWARFARE: The use of communications and cyberspace environments to disrupt enemy command and control systems, infiltrate sensitive intelligence information, disseminate decoy intelligence, infect/disable software networks, persuade troop surrenders, distribute propaganda and other technological means, usually as an adjunct to more traditional means of warfare. (See VIRTUAL WARFARE, SPACE WARFARE, HACKER, HACKTIVISM) (MP)
CYBOFREE : Cybofree is a term used to indicate the futility with which the mind tries to acheive perfection by using the body as a facilitator of pleasure.When a cyborg body iscreated solely for the purpose of self-gratification (ie) using the body as a facilitator of pleasure, the mind experiences a false sense of freedom called CYBOFREE.Iutility with which the mind tries to acheive perfection by using the body as a facilitator of pleasure. This term was coined by V.R.Manoj and Dr.Jayapaul Azariah in tntasy, Reality, Ethics and Education (FREE)" published in Eubios Journal of Asian and International Bioethics, November 2001. (VRM & JA ) http://eubios.info/EJ116/ej116b.htm
An organism or entity created by merging electronics with biology; for example a semi-robotic human. The term usually implies major integration of computer technology into living tissue such that biological limitations are transcended, rather than limited use of simple bionic technologies for the restoration of normal function. A recent example has been "remote controlled rats", directed by computer with the use of controlled stimulation of the brain centers which process the whiskers sense (to direct movement) and pleasure response (to control motivation). These semi-robotic rats may have uses for example in earthquake rescue, but could also be considered subjects of animal rights abuse. Another recent step has been a vision chip able to partially combat blindness by sending digitally video-recorded images directly to cybernetic attachments in the cortex of the human brain. Such technology not only has the capability to restore normal vision, but is also a first step towards infra-red, telescopic, microscopic or remote vision. Robotics experts such as Marvin Minsky and Hans Moravec imagine that the cyborg is the next phase of human evolution, endowing post-humans with incredible mental capacities, physical strength and longevity.

CYCLOSPORINE: An immuno-suppressive drug. This drug is of great importance to organ transplantation, because by suppressing the immune system of the organ recipient, it prevents rejection of the transplanted organ. However, cyclosporine does have problematic side effects. Much research is being done to discover a drug that can produce the immuno-suppressive effect with less extreme side-effects. (AG)
CYSTIC FIBROSIS: Disease which affects the sweat and mucus-secreting glands, resulting in chronic lung disease, pancreatic insufficiency, abnormally salty sweat, and in some cases, liver disease. (+DR) Its inheritance is autosomal recessive, with several hundred mutations found so far in the CFTR gene in the patients. The most frequent mutation, DF508, is present almost in every patient group around the world with, nevertheless, big differences in its frequency. In Caucasian population from Europe and USA, the frequency of DF508 as a cause of cystic fibrosis in patients varies from 45-88%, and in Latin America it varies from 25-66%.

DATA MINING: The process of knowledge discovery or retrieval of hidden information from data banks and collections of databases. Initial steps involve selection and pre-processing by an expert in the appropriate knowledge domain. Then patterns are identified using tools and techniques such as filtering, transformation, induction, cluster analysis, discriminant analysis, fuzzy logic, computer algorithms, case-based reasoning, intelligent agents and artificial neural networks. Information gleaned from data mining may then be interpreted, evaluated, incorporated into the existing knowledge base and modeled. (See DATABASE, KNOWLEDGE ACQUISITION) (MP).

DDT abbreviation for the polychlorinated biphenyl pesticide dichloro-diphenyl-trichloroethane. Owing to their estrogenic potency and biological stability, DDT and its major metabolite DDE (dichlorophenyl-dichloroethane) are implicated in many reproductive dysfunctions, best publicized being faulty calcium mobilization in egg shell production resulting in extinction or endangerment of birds of prey; such the bald eagle and the osprey. It is also believed by some scientists that the PCBs, such as DDT and DDE, may be implicated in falling sperm counts, increasing testicular cancer, hypospadias (abnormal penile development) and cryptorchidism (mal-descent of the testes) in humans over the last 50 years (see ENDOCRINE DISRUPTERS, POLYCHLORINATED BIPHENYLS & BIOMAGNIFICATION).

DEAD SEA SCROLLS: A collection of ancient scrolls found in 11 caves in Qumran, near the Dead Sea. These scrolls were discovered over 50 years ago by a Bedouin who was herding his goats. The find was a very rare one because these scrolls were written 2000 years ago, and parchment is a perishable material that generally does not survive many centuries. The climate of the Judean desert helped to preserve these scrolls over the many centuries. The language of the scrolls is generally Hebrew, although some scrolls were found to be written in Aramaic or Greek. The script is a variant of the one currently used to write Hebrew, although in a few texts an older script is also found. These scrolls were written between 100 b.c.e. and 100 c.e. by a group which lived in Qumran. Their lifestyle bears some similarity to a sect known as the Essenes in the writings of the historian Josephus Flavius, and so, the scrolls are often identified as Essene. The content of the scrolls is varied. Included are Biblical texts (Old Testament and Apocrypha), some of the commentaries of the Qumran sect on Biblical books, the rules and regulations of the Qumran sect, and correspondence. These texts are very important for comparison of Biblical manuscripts, knowledge of Hebrew of the 2nd Temple period, knowledge of 2nd Temple period Judaism, and knowledge of early Christianity and its early development.

DECADENCE: (Medieval Latin: decadentia "a falling away") Self-indulgent behavior usually characterized by wastefulness, moral corruption and cultural deterioration. The materialism, self-absorption and decline of religious values characterized by the West has inspired the term "Western decadence". To bridge this cultural divide, affluent countries can no longer remain apathetic to the needs of the poor, and neither can the limited Earth support a decadent lifestyle for all people of the world.

Deep ecology is one of the most ecocentric of the preservationist green ideologies, and may also be referred to as ecologism, deep green or Gaian viewnmentnologREEN) (MP)
DEEP DESIGN VALUE SYSTEMS:
Value systems which take into account the wider, long-term ecological issues of sustainability, esthetics and bioethics within the holistic framework of environmental management; for example by taking account of the fundamental importance of symbiotic relationships, a deep value system contrasts starkly with the simplistic and materialistically driven short-term approaches, which could well be described as "shallow design value systems" (see DEEP ECOLOGY).

DEEP FREEZING: Typically refers to the freezing of gametes (sperm and eggs) and embryos. Frozen human and animal semen are routinely used and more sophisticated techniques for eggs and embryos are being developed. The main ethical questions which arise in the context of human material are for how long gametes and embryos should be cryopreserved and what should happen to them if the donor(s) die. The Warnock Report (UK Committee reported in June 1984) recommended that storage of embryos could be for a maximum of 5 years and gametes for a maximum of 10 years and that said embryos and gametes could only be stored with the signed consent of the donors, and could only be used by the license holder responsible for storage for the purposes specified in the consent; for example, for infertility treatment or for research. The sale and purchase of human gametes and embryos should be controlled so as to avoid the risk of commercial exploitation. (See CRYOBIOLOGY, CRYOGENICS, CRYOPRESERVATION). (IP)

DEMATERIALIZATION: The process of reducing human consumption of materials. Although contrary to the current economic paradigm of growth, dematerialization will be essential for allowing equity of human wellbeing whilst conserving ecosystem life-support services in line with requirements for sustainable development. Eminent authorities such as the World Resources Institute and Wuppertal Insitute have cited the dematerialization requirement at Factor 10, or a staggering 90% reduction of current material consumption in developed countries. This was the central recommendation of the Factor 10 Club Carnoules Declaration in 1994. Factor 10 should be achievable using present technologies, and has been acknowledged by governments like Sweden, Denmark and Austria. There are lighter recommendations in the Club of Rome report Factor 4: Doubling Wealth - Halving Resource Use (1997). The dematerialization component of sustainability requires much work in the face of powerful growth-oriented global institutions and corporations. (See DEMILITARIZATION, OVERDEVELOPED NATIONS) (MP)
DEMENTIA: (Latin de 'out' + mens 'mind'). A progressive organic mental disorder characterized by deteriorated memory control, personality disintegration, confusion, disorientation and degeneration of intellectual capacity and function. Organic forms of dementia are generally progressive and incurable; however, recent studies have shown that about 10% of patients with dementia have conditions for which treatment can reverse the otherwise irreversible decline of mental function. Progressive dementia, known as senile and multi-infarct (arteriosclerotic) dementia, is most often diagnosed in the elderly.

'the people' +
Government by the people; state so governed by direct or representative representation. The system of government first evolved in ancient Greece when all citizens, including the poor, had access to the market place where the orators spoke and the politicians stood and took part in the democratic processes for the election of their rulers [Greek
the people and Kratein rule]. (IP)
DEMOCRACY PARADOX: See WESTERN DECLINE.
: literally: rule of the people. When it refers to a mode of governing in modern states, it describes a particular way of will formation that goes from the bottom up, that is, theoretically includes every citizen (Citizen does not coincide with human being. Citizen commonthe term citizen did not include individuals that were regarded as being of minor dignity, like women, slaves, peasants).
Since the purest form of democracy, that is, the participation of every citizen in every single act of governmental will formation (see Jean-Jaques Rousseau, Social Contract ) is not feasible in modern states, when we speak of democracy, we refeanction tt and transparent court system is essential in a democratic system.
Democratic also refers to a mode of will formation in communities or ad hoc groups of people, which includes everybody in the decision making process, instead of subjugating the group to the rule of one. (BP)
DEMOCRATIC : "Demos" means people in Greek, and a democracy is a society ruled by the people. Some democracies, like ancient Athens, are "direct" in the sense that the people directly vote whether they are in favour of, or oppose a proposal. Direct democracy still exists in relatively small groups, like the New England town meetings, kibbutz meetings, etc. Modern states, however, are usually representa t ive democracies, in which decisions are made by elected representatives. It is sometimes remarked that a democracy is dictatorship for four years. The idea of modern democracy developed together with the reorganization of church government during the 16t h and 17th century Protestant reformation in Europe. The Catholic Church heirarchy ruled from the top down, by means of the priesthood, who essentially told the people what to believe. The Protestant reformers introduced an idea of the "priesthood of all b elievers". They believed that if you read the (Christian) Bible with faith, the Holy Spirit will enlighten you, and your interpretation will be as valid, or more valid than the priestly interpretations. This lead to the idea that the congregation of b e lievers has the major authority in church government. The people, in Protestantism, do not take orders from the priest, but appoint or hire a minister to help them with this religious needs. The minister can be hired or fired by the people. Political dem o cracy is only a secular application of this religious idea, with elected politicians gaining their authority from the consent of the governed. Democracy has been strongly criticised by anarchists, who have argued that there is really no difference betw e en monarchy, democracy, dictatorship, etc. In any system, they argue, those who are gifted at manipulating and exploiting other people will rule. The differences between "elected representatives", "nobility", "commissars" etc etc, are only differences i n name. But in fact, the anarchists argue, they are all the same people. (FL)

DEPRESSION: Depression is a mood disorder characterised by severe emotional disturbance due to feelings of sadness, despondency, dejection or despair. A minimal requirement for its diagnosis is set down by the World Health Organization in the International Classification of Diseases as "a period of at least two weeks in which there is a depressed mood or loss of interest or pleasure in nearly all activities". Causes of depression may include bereavement, illness, anxiety, relationship breakdown, postnatal stress, work or social failure, seasonally affective disorder, loneliness, life instability or low self esteem. The illness also sometimes has a hereditary component, and may be divided into endogenous (implying a genetic predisposition), or reactive (induced by external life events). The condition may be difficult to diagnose as it ranges from mild melancholia (dysthymia) to major chronic depressive disorder. Common symptoms include: loss of interest in enjoyable activities, lowered initiative, inability to concentrate or make decisions, decreased efficiency, fatigue or sleep disorders, change in weight, sullen attitude, negativity, irritability, feelings of guilt or worthlessness, loss of hope, and possible contemplation of suicide. The majority of cases will undergo remission without treatment, however relapse is also common and a combination of psychological counselling and temporary drug treatment may be helpful (e.g. Prozac, Lithium or St Johns Wort).

DESCARTES, RENE: (1596-1650) French mathematician, physicist and physiologist, who wrote philosophical treatises (The Discourse on Method and the Meditations on First Philosophy) to attempt to make his science palatable to a religious and university world in which Aristotelian philosophy and science were so entrenched that they were almost regarded as inseparable parts of Christian doctrine. Descartes is regarded as the modern father of "dualism", the idea that we have both souls and bodies. It is generally accepted that, in Descartes' philosophy the soul and the body have equal status, or perhaps the soul is even more important. But his "real distinction between soul and body" really opens the way for a mechanistic scientific approach in which we can study the workings of the body through Cartesian physiology and mathematical physics with no need to take the soul into account. So perhaps Descartes is more the father of modern secular science than of spiritual philosophy. But Newton's fame quickly eclipsed that of Descartes.
Descartes lived at a time when sailing ships and empires were increasingly opening contact and trade with Asia. He called his major philosophical work: "Meditations", and in it he tries to forget by doubting, at least temporarily, his education, his cultural heritage, indeed to empty his mind of thoughts, imaginations and memories, until enlightenment in the form of what he called "clear and distinct ideas", should finally appear. The similarity to Zen and to the Tao are too great for so many years to have passed without someone's writing a doctoral thesis exploring the connexion. (FL)

DESENSITIZATION: (Latin: de "away from" + sentire "feel"). A technique used in behavioural therapy for the elimination of maladaptive anxieties associated with phobias and neuroses. Psychological trauma, feelings of shame or revolt from acts of violence, and inhibitions to aggression can also be decreased as a result of desensitization of the normal reactions due to frequent exposure. Such desensitization can result from repetitive violence without apparent consequences in media such as movies and video games, as well as various techniques common in military training.

Everything is determined in advance. There are at least three kinds of determinism: logical, theological and scientific.
Logical determinism is based on the Aristotelian Law of the Excluded Middle. There is no middle ground between truth and falsity. Any statement is either true or false. So a statement like "By the end of the 21 st Century, human cloning will be widespread and legal in most countries", is already true or already false. We just don"t know which. So there is no free choice about this matter or any other. Aristotle tried to avoid this problem, and to save free will, by declaring that the Law of Excluded Middle does not apply to contingent statements about the future. Those who believe in free will may applaud Aristotle, while those who do not may call his tactic artificial and unwarranted.
Theological determinism says that God already knows the future. Therefore, since God knows what we shall do tomorrow, tomorrow is already determined. Although we may be aware of ourselves actually making choices, God knew in advance exactly what choices we were going to make.
Scientific Determinism says that everything, which happens in the world, follows necessarily from the laws of science. Since we are ultimately composed of subatomic particles, are actions are the necessary outcome of the laws of particle physics. (See biological determinism). (FL)
Since this description of the First World is based around the achievement of wealth, wellbeing and some approximation of freedom and democracy, it is convenient to extend the continuum to point out that in many respects countries may be
developed, or wastefully rich and self-interested to the detriment of equity, other nations and the global environment. (See OVERDEVELOPED NATIONS, FIRST WORLD, NORTH, DEVELOPMENT, DECONSUMERISM, DEVELOPING NATIONS) (MP)
DEVELOPING NATIONS: Common descriptive term for countries with less economic wealth or social wellbeing with an emphasis on progress and the processes of development. Terms for developing nations have propagated in the search for political correctness and the right spin. The Third World descriptive system has endured despite criticism, geographical reorganization and diminution of the Second World. South is ave terms such as Less Developed Country, Newly Industrialized Country and Emerging Economy have been used in different contexts. It is ironic that some economically-minded commentators consider the stagnating Fourth World as not implied by the term developing - where td more on ING, SUSTAINABLE DEVELOPMENT) (MP)
DEVELOPMENT: (French: développer to unfold) 1. Biolved levelL ANOMALY, DEVELOPMENTAL POTENTIAL, GROWTH, LIFE CYCLE, ONTOGENY) (IP)
2. Environment and socioeconomics: Progress which increases the wellbeing of humans and the environment. Development is any activity or process which increases capacity to meet ecological needs and human quality of life. Too often it is accidentally or deliberately confused with the concept of growth, in particular economic growth including consumerism, commercialism, environmental destruction and demoralizing industries. Development has also been defined in many other more positive ways: poverty-reduction, modernization, infrastructure, more jobs and income, higher standards of living, more equity, democratization, increased freedom, fair trade, institutional reorganization, shift from capitalist modes of production, and socioeconomic transformation. It is internationally recognized that all large-scale development should adhere to sustainable principlest. (See SUSLTH, STATE OF THE ENVIRONMENT REPORT, DEVELOPING NATIONS) (MP)
DEVELOPMENTAL ANOMALY : Any congenital defect; such as congenital heart defect, spina bifida, intellectual disability, that results from a disturbance of the normal processes of growth and differentiation during the embryonic and/or fetal periods. (See DEVELOPMENT; DEVELOPMENTAL POTENTIAL; TERATOLOGY; TOXICOLOGY). (IP)
DEVELOPMENTAL PHYSIOLOGY: The study of the physiological processes as they relate to embryonic and fetal development. (See DEVELOPMENT; DEVELOPMENTAL POTENTIAL). (IP)
DEVELOPMENTAL POTENTIAL: The full expression of an organism's latent genetic capacity. Any child's genetic potential is determined by the product of genetic endowment and by the environmental conditions, especially during prenatal development. Since the reproductive health of the parents can improve or undermine the expression of their child's genetic potential, planned pregnancies (that is, the conscious separation of fertility from sexual pleasure) should become the ethically acceptable norm. Major reproductive health determinants are lifestyle, socioeconomic conditions, medical knowledge and available services. (See INTRAUTERINE GROWTH RETARDATION; ADDICTION; PREMATURITY; SUDDEN INFANT DEATH SYNDROME). (IP)
An evil angel. If there are spiritual beings at all, there is certainly no evidence that all of them are good. There might be some bad ones, who give people bad advice. It is not, therefore, clear that those people who are, or who claim to be "spiritual" are any more ethical than those who are not. So-called "spiritual" people, if they are not deluded, do not necessarily receive their spiritual inspiration from healthy sources. (FL)
DIABETES MELLITUS : a complex disorder of carbohydrate, fat and protein metabolism primarily caused by a) the absence or malfunctioning of the beta cells in the islets of Langerhans of the pancreas resulting in a deficiency or complete lack of insulin secretion or by 2) defects of the insulin receptors resulting in tissues being unable to utilize circulating insulin. Insulin and glucagon (released by the alpha cells of the islets of Langerhans) are hormones that regulate normal glucose concentration in the blood. There are two basic types of the disease. Type I diabetes (also known as juvenile diabetes or insulin-dependent diabetes) affects 15% of diabetics. Typically this form develops in children or young adults and these individuals have a total or near total lack of insulin and consequently need daily injections of insulin to prevent a life-threatening condition called ketosis where glucose and acids reach dangerously high levels in the blood. Type II diabetes (also called mature-onset diabetes, adult-onset diabetes or non-insulin-dependent diabetes) usually develops after age 40 in typically obese victims. In type II diabetes insulin is synthesized but not in sufficient quantity to control normal blood glucose levels so prompt treatment may minimize diabetic complications such as diseases of the eyes, kidney and nervous system. Gestational diabetes greatly increases the risk of stillbirth, birth defects and the development of large overweight babies due to the mother's excess glucose levels affecting normal fetal growth. Viral infections at critical periods of prenatal or postnatal development may also be implicated in the onset of the disease. Diabetes is often familial but a genetic predisposition is not the only factor since environmental and lifestyle variables interact with heredity to determine whether the disease will be expressed or not. The Australian Aboriginals have the highest rates of diabetes in the world where it is considered to be due to the abandonment of a traditional lifestyle in favor for a more sessile existence together with an unhealthy diet and excessive alcohol consumption. (See AUSTRALIAN ABORIGINAL). (IP)
DIAGNOSIS : (Greek dia 'thorough' + gnosis 'knowledge'). The process of identifying a disease or condition. In western medicine this is a procedure involving a medical history and listing the patient's symptoms, physical signs and results from the laboratory analysis of blood, urine, tissue biopsy or other substance which may identify clinical signs of disease. The final stage is to assemble all the relevant information in order to decide whether it fits a known pattern of disease. (IP)
DIAGNOSTIC GENETIC TESTING : Use of genetic testing in a symptomatic patient to aid the doctors in their diagnosis, treatment and management of the disease. (JA)
DIALYSIS : Dia = two, lysis = separate, Separation of soluable substances from colloids by diffusion through a semi permeable membrane, to dialyze (verb) to pass through a semi permeable membrane. (JA)
DIAZEPAM : A benzodiazepine sedative and tranquilizer traded under the name of Valium. It is predominantly prescribed in the treatment of anxiety, nervous tension, mild depression and as an anticonvulsant for epilepsy and similar disorders. Among the more serious side-effects is its addictive property, and since the drug was popularly prescribed even overprescribed to alleviate minor complaints and dissatisfactions numerous patients became dependent on the drug. (IP)
DICTATOR: Absolute ruler. Now generally used pejoratively though benign dictators exist, though rarely. (MR)
DICTATORSHIP : When dictatorship relates to a mode of governing in modern states, it labels the unrestricted power of one person (or a group of individuals), who actually monopolizes and exercises all political powers. Dictators shape rules without being subjugated to them, and their actions cannot be sanctioned by anyone. All these features stand in sharp contrast to DEMOCRACY. Dictatorship can also refer to a particular mode of exercising power within a community or an ad hoc group of people, which is unrestrained by exterior forces and not dependent on the will formation within the group. (BP)
DIDGERIDOO: traditional Australian Aboriginal wind instrument from the Northern Territory made from a witchety grub-hollowed out tree trunk and emitting a mesmerizing drone. The modern perception that all Aboriginal people played didgeridoo is based on stereotypes rather than fact as its use was limited and women were not permitted to play the instrument. Nowadays its a most popular instrument instantly recognizable as Aboriginal whether solo, accompanying lyrics or orchestral. Contemporary music has extended the traditioadition and also has a place in modern political life (see MENs BUSINESS). (IP)
DIETHYLSTILBESTROL (DES) a synthetic non-steroidal hormone with estrogenic properties which was promoted between the late 1940s until its prohibition in the early 1970s for the treatment of women at risk of miscarriage. During that period its potent teratogenicity was discovered with the in utero exposed offspring suffering an increased incidence of a rare form of carcinoma of the vagina and cervix and a range of other reproductive abnormalities in both sexes. (IP)
DIFFERENTIATION: An increase in complexity and organization of cells and tissues during development. (JA)
DIGITAL : (Latin digitus 'finger'). 1. Pertaining to a digit; that is, finger or toe. 2. Using numerical numbers (digits - as in a digital watch) that show a signal in terms of a series of numbers rather than a continuously varying value. Digital devices work by a counting process either mechanical or electronic. Early calculating machines; such as the abacus, counted with mechanical relays while modern calculators are electronic circuits. (See ANALOG, COMPUTER, QUANTUM COMPUTING). (IP)
DIGITAL FINGERPRINT: An invisible code embedded into a copyright image or other intellectual property such that any unauthorized use can be traced across the internet, sometimes even if the image itself has been digitally altered. (MP)
DILEMMA : Two lemmas, i.e. two different conclusions. A dilemma is a situation in which one can equally well arrive at either of two mutually contradictory conclusions, or decisions as to action, from the same data. Bioethics is often taught as a series of dilemmas, such as "to abort or not to abort", "to turn off the ventilator or to keep it running". Although this is not the only way to approach bioethics, it is a legitimate way. (FL)
DINOSAUR EXTINCTION: See MASS EXTINCTION.
DIPLOID: A full set of genetic material (two paired sets of chromosomes), one from each parental set. All cells except sperm and egg cells have a diploid set of chromosomes. The diploid human genome has 46 chromosomes (see haploid .). A nucleus with two sets of chromosomes (2n). total chromosome number specific for each species, double = 2n. (DM, JA +GK)
DIOECIOUS are organisms, such as most animals and some plants like holly bushes, which have separate sexes where some of the individuals can produce only female gametes and others only male gametes (Greek di double + oikion house) (see MONOECIOUS). (IP)
DIOXIN : Dioxins such as TCDD (2,3,7,8-tetrachlorodibenzoparadioxin) are among the most dangerous of the persistent organic chemical pollutants, are highly toxic in small doses, and have been implicated as carcinogens and endocrine disruptors. Dioxins are a by-product of the chemical industry, contaminants of herbicides used in forestry and agriculture, and were a component of Agent Orange. Dioxin-containing compounds have been recognized as hazardous and phased out in much of the developed world. (See PERSISTENT ORGANIC POLLUTANTS, SYNTHETIC HORMONE DISRUPTORS, POLYCHLORINATED BIPHENYLS, AGENT ORANGE) (MP & IP)
DIRECT ACTION: Protests outside the institutionalized framework, for example grassroots activism, Greenpeace-style tactics, illegal public demonstrations, protest movements, computer hacking, stoppage of work, prevention of transport, locking on to machinery, sabotage etc. (See NONVIOLENT DIRECT ACTION, ACTIVISM, HACKTIVISM, ECO-TERRORISM) (MP)
: Tissue or organ donation intended for the benefit of a designated recipient. (DM)
DISADVANTAGED: Persons lacking the basic resources or conditions believed to be necessary for an adequate standard of living. These may include, homeless persons, minority groups, etc. (DM)
include: Strategic Arms Limitation Talks (SALT I and SALT II), Strategic Arms Reduction Treaties (START I, 1991 and START II, 1993), Nuclear Non-Proliferation Treaty (NPT, 1995), Comprehensive Nuclear Test Ban Treaty (1996).
Conventions against Chemical and Biological Weapons include: Protocol for the Prohibition of the Use in War of Asphyxiating, Poisonous and Other Gases and of Bacteriological Methods of Warfare (1925), Convention on the Prohibition of the Development, Production, Stockpiling and Use of Chemical Weapons and on their Destruction (1993).
Conventions against Land Mines include: Convention on the Prohibition of the Use, Stockpiling, Production and Transfer of Anti-Personnel Mines and on their Destruction (1997).
National commitments against Missiles have generally gone through the Missile Technology Control Regime.
Agreements or restrictions on manufacture and trade in Conventional Weapons have been made difficult by the right of nations to self-defense, and economic incentives in countries with an extensive military-industrial sector of their economy. The drive to disarmament and demilitarization (See DEMILITARIZATION, WEAPONS OF MASS DESTRUCTION, CONVENTIONAL WEAPONS) (MP)
DISCLOSURE: Revelation of information, such as the risks and benefits or economic implications of clinical or experimental procedures, to help patients or research subjects make informed decisions. (DM)
DISCOURSE: Narrowly understood as talk but nowadays typically used much more widely to mean a whole way of thinking, understanding and even constructing reality, as, for example, in 'feminist discourse'. Habermas and others have used the phrase 'discourse ethics' when talking about the conditions (listening to others, being prepared to change one's opinions, etc.) that are necessary for valid debate among people preparatory to reaching a common ethical conclusion. (MR)
DISCRIMINATION: Selection between alternatives based on observable characteristics. Discrimination may be ethically appropriate or inappropriate. It is appropriate to discriminate in favour of a job applicant when she displays certain needed skills/abilities, e.g. excellence in teaching and research when appointing an academic, more than other candidates. With certain exceptions, it is inappropriate when the criteria used are such ones as sex, religion, ethnicity and age. However, there are many contentious areas. Is it acceptable to insist that airline stewards are below a certain age? Is it acceptable to favour Christian teachers for a Christian school? Will it be acceptable to test potential airline pilots to see if they have a genetic susceptibility to heart attack? (MR+GK)
DISEASE: Common-sense and widely used though difficult to pin down term generally held to mean either the absence of health or the presence of something that actively impairs full physical and/or mental functioning. Measles, cystic fibrosis and cancers are clearly diseases. But what about the menopause, crooked teeth or short stature? Without intending entirely to deny their objective existence, diseases are clearly also human constructions with a degree of cultural specificity. (MR)
DISEASES OF ADAPTATION : are stress-induced conditions; that is, diseases of exogenous non-infectious etiology such as hypertension, cardiovascular and renal dysfunction and gastric or duodenal ulcers. They are also sometimes called 'lifestyle diseases' (see GENERAL ADAPTATION SYNDROME, DISTRESS). (IP)
DISORDER, GENETIC : By characterizing the nature of the protein normally produced by the gene, greater understanding of the disease process can be obtained. Such an understanding help to assess the relationship of the protein to other body processes and how changes in the gene result in disease. These disorders in the genetic makeup of a person lead to disability and disease, see MULTIFACTORIAL DISORDERS, LATE ONSET DISORDERS, AUTOSOMAL RECESSIVE DISORDERS AND AUTOSOMAL DOMINANT DISORDERS. (JA)
See MEASURES OF DISPERSION
DISPUTE: Not as strong connotation as conflict, a dispute is an argument or debate, often involving material considerations, which can be settled by peaceful mediation, negotiation or legal means. (See CONFLICT) (MP)
DISPUTE RESOLUTION: See CONFLICT RESOLUTION
DISSENT: Difference in sentiment, such as an alternative opinion or separation from an established religion. Public dissent may be expressed in protest or activism, which require attention by the processes of democracy and peace building. (See ACTIVISM, PROTEST, PEACE BUILDING) (MP)
DISSOCIATION: (Latin: dis "apart" + sociatio "union") An emotional separation of normal thought processes from consciousness (dissociative disorder or reaction), for example in amnesia, somnambulism or lucid dreaming. Another form involves the splitting of individuality into multiple sub-personalities who may or may not be aware of each other, each with distinct behaviors and emotional development (dissociative identity disorder). (See DEPERSONALIZATION) (MP)
DISSOCIATIVE IDENTITY DISORDER:
DISSOLVED OXYGEN (DO): An important component of water quality, DO is a measure of the concentration of oxygen available for biochemical activity within a water body or sample. (See BIOCHEMICAL OXYGEN DEMAND) (MP)
DISTRESS : Unhappy stress from the Latin dis meaning negative. In biology stress is essentially reflected in the total rate of all the wear and tear caused by life and, although it is impossible to avoid stress, a lot can be learnt about how to keep its damaging side effects to a minimum. It is argued that many common diseases can be avoided if the adaptive response to stress were more moderate and thus better controlled. For example, many nervous and emotional disturbances, high blood pressure, gastric and duodenal ulcers, certain types of sexual dysfunction, allergic, cardiovascular and renal derangements appear to be essentially diseases of inadequate adaptation. It helps to know your personal strengths and weaknesses and so adjust your life, as much as is possible, to function within these constraints. In addition, the routine incorporation of knowledgeable nutrition and relaxation (meditation, sport, music) and the ability to reduce other sources of stress when subjected to a certain particular stress help to heighten eustress and conserve the body's energy for use in areas of maximum demand and effect. (See EUSTRESS; STRESS; GENERAL ADAPTATION SYNDROME). (IP)
See POPULATION DISTRIBUTION.
DIVORCE: Legal dissolution of marriage. In the UK and Australia, for example, irretrievable breakdown of marriage becomes the basis of divorce. The five main proofs of irretrievable breakdown are adultery, unreasonable behavior, desertion for two years, living apart for two years or when both partners consent to divorce. A divorce is granted provided the court is satisfied that financial and child-care arrangements are reasonable. (See MARRIAGE). (IP)
DMT: DMT is short for dimethyltryptamine, among the most powerful of the hallucinogenic recreational drugs. Usually smoked in a safe environment, its action is similarly intense but much shorter lasting than that of LSD. (See HALLUCINOGENS, LSD). (IP)
DNA, DEOXYRIBONUCLEIC ACID: The molecule that encodes genetic information. DNA is a double-stranded molecule held together by weak bonds between base pairs of nucleotides. There are four nucleotides in DNA: adenosine (A), guanosine (G), cytidine (C) and thymidine (T). In nature, base pairs form only between A and T and between G and C, thus the sequence of each single strand can be deduced from that of its partner. Deoxyribonucleic acid usually found in chromosomes, contains genetic triplet code - structure elucidated by Watson and Crick in 1953 Determines the sequence of amino acids in a protein. (DM, JA)
DNA COMPUTER: A computer which uses dissolved DNA molecules in a test tube for calculations rather than silicon chips (ordinary computers) or electrons (quantum computers). Leonard Adelman has demonstrated their efficacy at the University of Southern California. These energy-efficient machines are capable of performing multitudinous simultaneous calculations, providing enough power to crack codes and solve problems too complex for ordinary computing. Unlike quantum computers, they remain digital, with specific gene sequences coded as 1 or 0. Chemical processes are used for calculating, such as cutting DNA sequences with restriction enzymes and reproducing them with the polymerase chain reaction. Minor drawbacks include their technical intricacy, bulky proportions and the decay of DNA molecules, meaning that information cannot be stored for long periods of time data must be transferred to silicon computers for reliable memory. The principal drawback is their lack of versatility a unique sequence of chemical reactions is required to address each new problem, unlike all-purpose silicon computers. DNA computers may have applications similar to heavy-duty mainframe supercomputers. (See QUANTUM COMPUTING, MOLECULAR COMPUTER, COMPUTER) (MP)
DNA DATA BANKS: Collections of genetic information that are maintained for clinical, research, or law enforcement purposes. (See DATA BANKS, DNA FINGERPRINTING). (DM)
DNA FINGERPRINTING: A genetic identification procedure in which band patterns of DNA (the DNA fingerprint) from one individual or an unknown individual are evaluated for similarities with those of a known individual. Used in forensic medicine and immigration cases, and investigation of paternity. (See DNA DATA BANKS, GENETIC SCREENING). (DM)
DNA HYBRIDIZATION TECHNOLOGY: The formation of double-helix deoxyribonucleic acid from two complementary single strands. The technique is useful for comparing genome relationships between different species. Comparing human and chimpanzee DNA by the process of DNA hybridization, reveals that the DNA of humans and chimpanzees is much more similar (1.6% difference or 98.4% similarity in DNA sequences) than would be expected, given the considerable morphological differences between the two species. More recently, DNA sequencing of genes fully supports and adds detail to the data obtained from hybridization technology. (See RECOMBINANT DNA TECHNOLOGIES). (IP)
Segments of single-strand DNA that are labeled with a radioactive or other chemical marker and used to identify complementary sequences of DNA by hybridizing with them (see
DNA RECOMBINANTS: See RECOMBINANT DNA RESEARCH.
DNA SEQUENCE: The relative order of base pairs, whether in a stretch of DNA, a gene, a chromosome, or an entire genome. (DM)
DNA SEQUENCING TECHNOLOGY: S ee DNA hybridization technology.
DNR (DO NOT RESUSCITATE): A decision or order not to administer life-saving treatment, especially CPR, the next time a patient begins to fail. With respect to adults, and children sufficiently mature and intelligent to participate in the decision, it has been generally accepted that DNR is appropriate only if the patient has given an advance directive to that effect. But literature has begun to appear in which it is argued that even lacking such directives, staff and/or family can make these decisions if they clearly consider DNR to be in the "best interests" of the patient.
When the patient has not made an advance directive, a DNR decision involves grave seriousness. And even if the patient has made an advance directive, it is not always clear whether the patient's intentions apply at a certain time, or whether the patient may have undergone a change of mind. And in some countries (e.g. Israel) advance directives are not legally binding. In some places even a registrar can make a DNR decision with no need to consult others. In others, the hospital ethicist or ethics committee must be consulted. More attention might be paid to making DNR decisions ward decisions involving more than one physician, together with nurses, social workers and, of course, .whenever possible the patient and the family.
Some bioethicists think that there should be international, or nationwide, or at least hospital-wide guidelines for DNR. But others think that the issue is so complicated and the differences among individual cases so subtly different, that it is healthy for each ward staff to exercise its own judgment and conscience. (FL)
DO NO HARM: The principle of 'doing no harm' or 'not doing harm' is generally thought of as perhaps the first duty of a doctor or other health professional and appears in the HIPPOCRATIC OATH (q.v.) in the form 'at least, do no harm'. (See PRIMUM NON NOCERE ).
'Doing no harm', or NONMALEFICENCE (q.v.), is also often thought of as a duty incumbent on all moral agents. Some moral philosophers recognise no distinction between nonmaleficence and BENEFICENCE (q.v.) - 'doing good' - but most hold that they are distinct, albeit complementary. In many countries there is a legal requirement for a person not to harm others, including strangers, whereas there are only rare circumstances in which a person is legally required to help strangers. (MR)
DOCTOR-ASSISTED SUICIDE: The taking of a lethal drug provided by a doctor for the purpose of ending the life of a terminally ill patient. Central to the euthanasia debate is the reduction of extended pain and human suffering. However, the legalization of euthanasia and the concept of assisted suicide have also highlighted the dilemma within medical ethics of whether or not assistance is a breach of the Hippocratic Oath and whether the application of advanced medical technology is a breach of patient autonomy. Most Western countries have passed laws making doctor-assisted, physician-assisted or medically-assisted suicide illegal. (See EUTHANASIA; SUICIDE). (IP)
An idea or doctrine which is not supposed to be questioned, if one is not to fall out of favour with a political, religious, scientific, medical, academic, etc., establishment. Dogmas are often false. But the fact that something is a dogma does not guarantee that it is false. Some dogmas are true. In science, Darwinian evolution is a kind of a dogma. But in some religious circles, its denial is a dogma. In medicine, the idea that brain death is really death is becoming a dogma. (FL)
DOLLY: A transgenic cloned farm sheep, produced by Dr. Ian Wilmut, Roslin Institute, Edinburgh, through a technique of somatic nuclear transfer in 1997. Died in 2003. See also TRACY and POLLY. (JA)
DOLPHINS: 32 species in 17 genera in the family Delphinidae and five species in four genera in the family Plantanistidae. Some people believe that dolphins have similar intellectual abilities and complexities of social organisation to the Great APES (q.v.) and so deserve comparable ethical regard. Most biologists, though, hold that this overstates the mental faculties of dolphins. Large numbers of dolphins die in fishing nets put out to catch tuna and other fish. 'Dolphin-friendly tuna' sells well in some countries as a result of consumer objections to such deaths. (MR)
DOMAIN: 1. An area of land or habitat occupied by a particular individual or species. (See POPULATION DISTRIBUTION) 2. Descriptive term for a general collection of related pieces of information, usually studied by specialists within a particular profession; a domain of knowledge. (See KNOWLEDGE) (MP) 3. A discrete portion of a protein with its own function. The combination of domains in a single protein determines its unique overall function. (DM)
DOMINANT: A trait or condition that is expressed in individuals who have a single version of a particular gene. (DM)
DOMINANT PARADIGM: The prevailing epistemological framework or world-view, entrenched in place by inertia, tradition and established institutions. The current dominant social paradigm is techno-centric, militaristic and capitalistic, based on hard energy and hard power, treats economics as an end in itself, condones competitive, complex and fast lifestyles, places a low value on nature by destroying it for economic growth, and places a low value on human compassion evidenced by a lack of concern for other species, other people or for future generations.

DONOR CARDS: Cards on which a person notes their preferences regarding donation of their organs after death. (See BRAIN DEATH, ORGAN TRANSPLANTS). (DM)
DONOR GAMETES: Eggs or sperm donated by individuals for medically assisted conception. (DM)
DONOR INSEMINATION (DI): also known as artificial insemination by donor. DI is the insemination of a woman with sperm from a donor other than her husband or defacto partner. DI is much more successful than husband/partner insemination with a reported 60% birth rate after six insemination cycles and is, therefore, one of the major treatments for male infertility. The technique is routinely used in Australia, Europe, and the US. As an example of its popularity, over 30,000 DI births were registered in the US in 1987. (See ARTIFICIAL INSEMINATION, ARTIFICIAL INSEMINATION BY HUSBAND). (IP)
DOPAMINE : Is a major neurotransmitter coordinating brain function through an extensive network of synapses. Dopamine functions as the messenger of the brains reward system; that is, it generates the subjective feeling of pleasure or happiness and for this reason has been dubbed the courier of addiction. Heroin, cocaine, each drug's characterones that control tha and acute schizophly-induced manic-depressive psychosis. (See HAPPINESS; BRAIN NEUROTRANSMITTERS; LIMBIC SYSTEM; ADDICTION; SCHIZOPHRENIA). (IP)
DOPE: Colloquial for marijuana (or recreational drugs in general). "Dope" refers not only to the brains dopamine neurotransmitter but also to the dumb or "dopey" behavior of the stoned marijuana smosarily the emotional mind and its creativity). For example memorization, sustained concentration and attention to arithmetic are temporarily disorganized. (See MARIJUANA). (IP+MP)
DOUBLE BLIND EXPERIMENT: An experiment or medical trial where neither the researcher nor the subjects know which treatments or placebos are given to which subjects. (See CLINICAL TRIALS, EXPERIMENTAL GROUPS, CONTROL GROUPS, PLACEBO) (MP)
DOUBLE EFFECT, LAW OF or DOCTRINE OF or PRINCIPLE OF:
The theory that an evil effect is morally acceptable provided a proportional good effect will accrue, evil is not intended, the evil effect is not the means to the good, and the action is not intrinsically evil. (See AQUINAS, THOMAS). (DM)
DOUBLE HELIX: The shape in which two linear strands of DNA are bonded together. (DM)
DOVE: 1. A bird from several species within the pigeon family Columbidae, often smaller than the pigeons and white or blue-gray. A dove is said to have delivered an olive branch to Noahs Ark to indicate the end of the great flood. The dove is considered a symbol of peace, innocence and gentleness. 2. A colloquial term for a politician or international statesperscy, conciliation and peaceful resolution over threats of aggression or armed conflict. (See HAWK) (MP)
DOWN'S SYNDROME: Due to abnormal meiosis, non separation of a paired chromosome resulting in trisomy 21 aneuploidy in humans with 24 chromosomes. Symptoms mental retardation, mongoloid eyefolds, short stature, abnormal hands, feet and palm prints. See SYNDROME. (JA)
DREAM: (Middle English dreem 'joyful noise'). The manifestations of conscious thoughts, feelings and images during the rapid-eye-movement stage of sleep. Sometimes a dream may actually be acted out by the dreamer as in, for example, sleep-walking, sleep-talking and the performance of other acts during sleep which the dreamer has no recollection of on awakening. The whole question of the interpretation of dreams was put on a new basis in the 20 th century by the work of Sigmund Freud and his followers. Freud and his school of psychoanalysts regarded the dream as the direct road to the 'unconscious' mind and consequently used it as a means to the patient's unconscious thoughts, emotions and illnesses. Dream analysis - the process of gaining access to the unconscious mind by means of examining the content of dreams, usually through the method of free association - is accepted as being a useful tool in psychotherapy. (See FREUD, SIGMUND). (IP)
DREAMING ECOLOGY see DREAMTIME
DREAMTIME or DREAMING: the Dreamtime refers to the beginning or Creation in the ancient past during which Australia was constructed as a land of hundreds of distinct Aboriginal countries. The Dreaming, on the other hand, refers to the ongoing connection over all time as defined by language, belief systems, cultural practices and social organization as guided by the spirit ancestors. The Dreamtime is the story of how the Spirit Ancestors created the land with its natural features, sky, sun, moon and star systems, all based on the understanding of Earth as Mother - the giver and provider of all life. The Dreamtime also provides the spiritual affiliation with the land and the method of responsible custodianship to land which cannot be owned, sold or given away (see Corroboree; Sacred Sites & Totemism). Spiritual beliefs and practices vary widely among Aboriginal language groups, however, central to their spirituality is the identification with land and the Dreamings creative force where land remains eternally sacred - the source from which the ancestral spirits continue to render to its people the biological and sowisdom for healthy living. The Dreaming, as representing a complex social organization of political systems and relationships of peoples to land and spiro assumed that the land was not being owned; thus he adopted the concept of Terra Nullius (land belonging to no one) and claimed Australia for the EmpireOW SERPENT; NATIVE TITLE LEGISLATION - AUSTRALIA & MABO CASE). (IP)
DRIFTNETS: Large gill nets of up to ten kilometers in length with floats along the upper and weights along the lower edge, designed to entangle fish whilst drifting in the current. When lost to the ocean, driftnets continue "ghost fishing" for long periods of time. Maligned as "walls of death" because of their large by-catch including marine mammals, their use on the high seas has been curtailed since 1991 by the Wellington Driftnet Convention and the 1993 UN General Assembly moratorium on large-scale driftnets. (See SUSTAINABLE FISHING) (MP)
DRUG: (French drogue "chemical material") any substance taken orally, or applied topically, or injected subcutaneously, intramuscularly or intravenously, or applied to a body cavity to treat or prevent a disease or condition. A drug when taken into the body modifies one or more of its functions. (See ADDICTION, RECREATIONAL DRUGS, DRUG ABUSE, harm minimization). (IP)
DRUG ABUSE: Drug abuse refers to the deliberate long-term self-administration of a recreational or medical drug with uncontrolled frequency, excessive dosage, and/or in combination with other drugs. This behavior is distinct from drug misuse, which is accidental or intermittent use of drugs in a way not prescribed by a physician. The adverse consequences of drug abuse may be the development of drug tolerance, dependence and addiction with resulting personal health and wider social impacts. There is also the view that under certain circumstances 'responsible' recreational use, or self-medication, of some substances where control over frequency and dosage is strictly maintained may, in fact, be efficacious and not necessarily adversely impact on the normal processes of life and health. In the latter instance the double standard is evoked when illegal drug use is automatically assumed to be drug abuse, and abuse in relation to legal drugs, such as nicotine and alcohol, is under-recognized.

DRUG TESTING: 1. Random mandatory drug tests in the workplace are becoming a common feature of corporate life in developed countries. This is considered by some an imposition on recreational freedoms, however may be justified especially in careers involving fair competition (e.g. sportspeople), considerable responsibility (e.g. politicians) or risk to human life (e.g. pilots). 2. Voluntary ecstasy-testing booths have been used to assess drug constituents and strength, for example in Dutch nightclubs as a harm-minimization initiative. (See HARM MINIMIZATION) (IP+MP)
DRUG TOLERANCE: Tolerance in this respect refers to the adaptation of the cellular biochemistry to accommodate a pharmacologically active substance so that progressively larger doses are required to achieve the same physiological and/or psychological effects previously achieved from smaller doses. Tolerance management is an important concept for the occasional medicinal or recreational drug user. The maintenance of a low tolerance to a drug minimizes the loss of effectiveness, health impacts, monetary costs and likelihood of addiction. (See addiction, DRUG DEPENDENCY). (IP+MP)
DUAL INHERITANCE THEORY: refers to studies that view culture and genes as providing separate but linked systems of inheritance, variation, and fitness adaptations in order to yield distinct, but interacting, evolutionary change. Inheritance in this instance refers to the idea that culture is information that is acquired socially; i.e., non-genetic, contrasting with information acquired through genetically inherited mechanisms (see MEME; HUMAN BEHAVIORAL ECOLOGY AND EVOLUTIONARY PSYCHOLOGY).

DUCHENNE MUSCULAR DYSTROPHY: A genetic disorder. (See MUSCULAR DYSTROPHY)
DUE PROCESS: Legal procedures for the protection of individual rights in accordance with established standards of fairness and justice.
DUPLICATION. Gene or DNA segment that is found twice on the same chromosome. Multigenic families have evolved by duplication of an ancestral gene. Duplications can also be aberrant, in that they arise through chromosomal rearrangements during meiosis at particular breakpoint regions. (See also DELETIONS). (GK)
DURABLE POWER OF ATTORNEY: See ADVANCE DIRECTIVES.
DUSTSTORMS: Are an unwelcome feature of the weather over arid areas, particularly at times of draught. Due to the destruction of much of the vegetation and the drying out the land, duststorms in Australia have become more severe since European settlement illustrating the importance of land management in the fight against soil erosion and climate change. Overstocking and intensive agriculture can turn areas into dustbowls (see SOUTHERLY BUSTER). (IP)
DUTY TO WARN: A health professional's obligation to breach patient confidentiality to warn third parties of the danger of their being assaulted or of contracting a serious infection. (See CONFIDENTIALITY ).
DWORKIN, ANDREA: (1946- ). American feminist writer who portrays a deeply pessimistic view of modern society in which men are presented as constructing images of women that lead to hatred and violence such as rape, battering and psychological assault. These scenarios are described in her works 'Woman Hating' 1974; 'Our Blood: Prophesies & Discourses on Sexual Politics ' 1976; 'The New Woman's Broken Heart' 1980. Dworkin actively campaigns against pornography which, since it violates equal human rights, she regards as a foremost form of sexism. These social issues are dealt with in 'Take Back the Night: Women on Pornography' 1980; 'Pornography: Men Possessing Women' 1980. (See BEAUVOIR, SIMONE DE, GREER, GERMAINE, SEXISM). (IP)

In 1992 in Rio de Janeiro, Brazil, the world's governments met in the United Nations Conference on Environment and Development (UNCED). Five major agreements came of this so-called Earth Summit:
Agenda 21 - a broad, 40-chapter statement of goals and potential programs related to sustainable development
The Rio Declaration - a brief statement of principles on sustainable development
The Biodiversity Treaty - a binding international agreement aimed at strengthening national control and preservation of biological resources
The Statement of Forest Principles - a non-binding agreement on development, preservation, and management of the Earth's remaining forests
The Framework Convention on Climate Change - a binding international agreement that seeks to limit or reduce emissions of gases associated with the potential for global warming. (RW)
EASTERN PHILOSOPHY: Buddhist, Hindu, Shinto, and other philosophies from South and East Asian countries are usually thought of as Eastern Philosophy. It is debatable whether there are common points uniting all Eastern philosophies and distinguishing them from Western ones. (FL)
EASTERN RELIGIONS Religions originating in Asia, particularly those which originated in the subcontinent and eastward, and are not based upon Jewish, Christian or Muslim scriptures. Some Eastern religions have texts which are designated as sacred, others are based on oral traditions. (AG)

ECNC: European Centre for Nature Conservation.
ECO-: (Greek: oikos "house") Combining prefix indicating ecology or an ecological component (e.g. ecocentric, ecotourism, ecocide). It is informative to note that both the words ecology and economy are derived from the same Greek root oikos ; eco-logy (- logy "the study of" from logos "word") being the scientific study of the house, and eco-nomy (from nemein "to manage") being the management of the house. It is therefore easy to see that the economy should be subservient to and dictated by ecology - rather than todays apparent economic orthodoxy of the other way around. (See ECOLOGY, ECONOMY) (MP)
ECOBALANCE: Ecological balance, Interaction between the environment and the living beings to bring about a steady-state - balance is not a point but a condition. (JA)
ECOCENTRIC: Viewpoint giving importance to ecological processes, living in tune with nature, an accent on ecobalance, recycling, conservation of natural resources. (JA)
ECOCIDE: Ecological genocide; the total destruction of the natural ecology and environment to make way for humans and their desires. Typically, ecocide tends not to have legal recognition as an atrocity or crime. (MP)
ECOCUISINE: (Greek oikos 'house' + French coquere 'cook'). The preparation and cooking of wild species, perhaps even ecologically endangered species. The underlying psychology of killing endangered species stems from the acceptance that humanity is prepared to nurture and protect commercially importance species while it condones mass extinctions in the wild. The expectation is that once an ecologically unique dish has gained popularity, the species will be saved through efforts at sustained agri- aquaculture, domestication, or enhanced environmental protection. Several formerly threatened species; such as the crocodile, have been given a reprieve by enhancing their gastronomic attractiveness. (See SUSTAINABLE DEVELOPMENT PRINCIPLES; ECOLOGICALLY SUSTAINABLE DEVELOPMENT). (IP)
A concept of living in consonance with nature, employing technology that preserves the beauty and integrity of ecosystem. (JA)

ECOLOGICAL ECONOMICS: See NATURAL CAPITAL, ETHICAL INVESTMENTS, ENVIRONMENTAL VALUATION.
ECOLOGICAL FOOTPRINT: A measure of consumption, our ecological footprint is an amount of land area which represents our resource use. Ecological footprint analysis converts our use of materials and energy into hectares of land per person required to provide these resources. It is an illustrative indicator of individual or collective human impact which highlights concepts such as natural capital, carrying capacity and ecological limits. (See CONSUMPTION, FLOWS) (MP)

An innate awareness of the total interdependence of living things functioning as both a scientific and philosophical moderator as expressed in the phrases thinking ecologically and an ecological point of view. (See ECOLOGICALLY SUSTAINABLE DEVELOPMENT; GAIA HYPOTHESIS). (IP+MP)
ECOLOGICAL JUSTICE / ECOJUSTICE: A principle that links social justice with environmental quality, that which is due to the ecosystem. The right of each components of an ecosystem to be free from human exploitation and to be free from destruction, discrimination, bias and extinction. A principle that deals with solidarity of creation that ensures sufficiency and sustainability avoiding disposal of /poisonous/ toxic/hazardous wastes like nuclear wastes that threaten the fundamental right to clean air, land, water and food. (JA)
ECOLOGICAL LOCATION : A composite expression referring to the combination of location where the human and nonhuman is situated in the web of biotic communities, contrasting with social location which is restrncentrates on the location of all the biospheres inhabitants and how these interspecies relatigy. (See SUSTAINABLE DEVELOPMENT; GAIA HYPOTHESIS). (IP)
ECOLOGICAL NICHE: A particular physical habitat or resource that is exploited by an organism. Niches often are defined in terms of food (e.g., carnivore or detritivore) or a functional role in an ecosystem (e.g., primary producer, consumer). (See NICHE, NICHE DIFFERENTIATION). (RW)
ECOLOGICAL PROCESSES: Ecological processes are the which Ecosystem services are They include environmental processes such as chemical transformation, phase transfer and mass transfer. Evolutionary processes include natural selection, punctuated equilibrium and speciation. Biological development processes include meiosis, mitosis, differentiation, growth and ontogeny. Human socioeconomic development introduces a whole new set of disruptive ecological processes, investigated by Environmental Impact Studies. (See PROCESS, ENVIRONMENTAL PROCESSES) (MP)
See RESTORATION ECOLOGY.
ECOLOGICAL SUCCESSION: The sequence of ecological communities that grow in a habitat. Typically, a pioneer community becomes established after a disturbance. This pioneer community will be displaced by various successors until the establishment of a climax community, which, by definition, is essentially stable until the next disturbance. (RW)
ECOLOGICALLY SUSTAINABLE DEVELOPMENT: A variant of the term "Sustainable Development" emphasizing the underlying importance of ecological integrity to human life. The ecological component cannot however be separated from the economic and social components. Theoretically committed to the concept, the Commonwealth Government of Australia (1990) defined it as follows: "Ecologically sustainable development means using, conserving and enhancing the communitys resources so that the ecological processes on which life depends, are maintained, and the total quality of life, now and in the future, can be increased." (See SUSTAINABLE DEVELOPMENT). (MP)
ECOLOGISM: A green philosophy which emphasizes the need for deep social, economic, political and environmental reform in preparation for a post-industrial sustainable future - in comparison to environmentalism, which involves reform within the boundaries of the current sociopolitical system. Ecologism has similar viewpoints to deep ecology, including recognitions of an ecocentric perspective, biophilia, limits to growth, and the radical restructuring of existing institutions and ideologies.

"house") The branch of biology dealing with living organisms" distribution, behavior, mode of life and relations to their surroundings. The word was coined by the German biologist Ernst Haeckel in 1869, derived from the Greek root "oikos" which means "dwelling place, place to live, house" (i.e. environment). Defined as the study of the structure and function of nature in which human beings are a part. Ecology includes all the patterns of relationship between all organisms and their environments.

ECONOMETRICS : Application of mathematics and statistical principles in economics so as to test economic theories and their relationship and to make quantitative predictions. (JA)
ECONOMIC GROWTH: See GROWTH
ECONOMIC SANCTIONS: Economic sanctions have been questioned on grounds of effectiveness, equity and ethics. They impose budgetary losses to neighboring third-party states, or may involve unilateral political gain or manipulation. But most importantly, economic sanctions usually have a devastating effect on community health and wellbeing in the affected country. Limited resources may be disproportionately allocated to elites and the military, leaving innocent citizens to bear the brunt of the impacts of the sanctions. For example, the Oil for Food Programme during United Nations sanctions on Iraq was inadequate to prevent an estimated 5,200 preventable deaths in under 5-year olds per month between 1991 and 1998 (UNICEF 1999) due to lack of access to basic facilities. (See SANCTIONS) (MP)
The branch of biology investigating the physiological structures, functions and adaptations which enable organisms to survive in interaction with their ecosystem and physical environment. (MP)
ECOPSYCHOLOGY: Psychological study of the human mind in relationship, interaction and affinity with nature. It has been a long-held theme that divorce from nature (or the natural order of things, e.g. Macbeth ) may precipitate mental instability. This may be of relevance in this modern world of invented physical and virtual environments. (MP)
ECOSPHERE: biosphere is an ecosphere, meaning the existence of various types of habitats and biomes. Indicates the living relationship between all of earths' living beings with the physical environment. Ecosphere = Biosphere(JA)
ECOSYSTEM first proposed by the British ecologist A.G. Tansley in 1935.It is derived from two words, ecology and systems to mean ecological systems, shorted to ecosystem. A functional unit and a dynamic system. It signifies the interaction between community and abiotic components such as matter and energy. (See also MICROECOSYSTEM) (JA)
Biodiversity impacts of ecosystem fragmentation include disruption of migration and foraging routes, reduced genetic exchange, isolation of ecological communities and exposure to edge effects, weed invasions etc. Experimental studies reviewed by E.O. Wilson suggest that a tenfold decrease in land area will approximately halve the number of species present, although the specific area-species curve is dependent on the ease of dispersal of given organisms. As with conservation of endangered species, focus has been on the
of small size on population persistence, and must address the
of such reductions in size and connectivity. These causes include expansion of human-dominated ecosystems, creation of edges (e.g. roads), creation of barriers (e.g. dams), land clearing, monoculture, hunting/harvesting, removal of food-web species, separation of mutualistic organisms, habitat competition from introduced species, introduced predators, and other ecosystem disruption and destruction. (See HABITAT FRAGMENTATION, HABITAT DESTRUCTION, EDGE EFFECTS, BUFFER ZONES, WILDLIFE CORRIDORS, RESTORATION ECOLOGY) (MP)
ECOSYSTEM SERVICES: Humans are ultimately dependent upon the functions and services of ecological systems. Ecosystem services are the supply and restoration processes essential to the functioning of the life. They may break down wastes (e.g. biogeochemical cycles), provide shelter, energy and oxygen (e.g. forests) or protect us in other ways (e.g. the ozone layer). Although usually taken for granted, these services are provided free by ecosystems, but end up costing heavily if damaged or destroyed. Essential ecosystem services are critical natural capital which must be conserved to provide our global life-support system. (See CRITICAL NATURAL CAPITAL) (MP)
ECO-TERRORISM: The use of fear and violence in the cause of environmentalism or to save ecology facing destruction. Or more broadly, use of violence in either the activist protection or the commercial extraction of ecological resources. So-called eco-terrorist groups such as the Earth Liberation Front (ELF) may conduct illegal activities, usually against property, but lives are also confronted and lost as a result of ecocide, inappropriate technologies, habitat destruction, threats to biodiversity, justifications for war, and ironically some officially sanctioned fighting against illegal loggers and big-game wildlife poachers.

EDUCATION: (Latin: educatio "rearing" or "bringing up") Systematic instruction, usually of the young, which provides people with the knowledge, skills and wisdom necessary for them to become active members of society. In its widest sense education includes the life-long process of development and maturation, but is more officially restricted to those influences brought to bear on children, adolescents and young adults preparing for the workforce. In ancient times the Greeks were one of the first civilizations to provide schooling and organized instruction (education). Jewish education also developed early, following along the lines of Old Testament injunctions regarding the training of children, and the Arab world too was very scholarly. The 12 th century saw the rapid development of learning in Europe during the Renaissance, heavily indebted to both Arabic and Hebrew scholarship. With the rise of Christianity, schools were instructing this religious doctrine as well as subjects such as the liberal arts, grammar, logic, arithmetic and music. The most famous university was in Paris, the chief center of philosophy and theology, while the prototype universities were Englands Oxford and Cambridge. In Catholic countries the church maintained control of education until more recently. By the 19 th century new approaches were coming to the fore, heralding, in the 20 th century, a wide variety of secular institutions such as Montessori schools and Progressive Education Movements which allow practical, self-paced development. It is now generally recognized that the state has a duty to provide education for all its citizens, for example the United Nations Development Programmes Human Development Index uses adult literacy and education enrolment as two of its four measures. Most of the trends are for increased up-front fees for attendance at the tertiary (university) level. Australia, for examps a non-discriminatory scheme in which payment of fees can be deferred until later entry into the workforce. Pr in poor countries like Vietnam, seem reprehensible.

EFFECTIVENESS: Effectiveness, or efficacy, is a mot just financial but in an overall integrated and sustainable way. The most economically efficient process may not prove be the most effective. (See EFFICIENCY) (MP)
EFFICACY: See EFFECTIVENESS.
EFFICIENCY: 1. Mechanics: a measure of the ratio of work done to energy supplied. 2. Economics: The same concept applied to money; the ratio of value of output to value of input. Productive efficiency is the least-cost set of technologically sufficient inputs, and allocative efficiency is putting scarce resources to the most useful purposes. Different interpretations have included the straightforward economic efficiency of Adam Smith, the social employment efficiency of John Maynard Keynes, and the adaptive efficiency of Joseph Schumpeter with investment in technology and creativity. Clearly there are many forms of efficiency, others relating to the rights of workers, environment, corporate behavior, and efficiency towards sustainable development and social values. All forms of efficiency must be considered to provide balance in economic policy. Efficiency is not necessarily the same as effectiveness - depending on whether the balance of focus is on the efficiency or the equity component of economics. (See EFFECTIVENESS, EQUITY) (MP)

EINSTEIN, ALBERT : (1879-1955). German-Swiss mathematician/physicist and originator of the theory of relativity. Einstein's insight pointed out that time and space are not absolute but merely relative to the observer and that in the case of rapid relative motion involving velocities approaching the speed of light, phenomena such as decrease in size and mass are to be expected. His predicted equivalence of mass (m) and energy (E) is stated in the equation E = mc 2 , where c is the velocity of light. This relationship was strikingly demonstrated in the production of nuclear power and the explosion of the atom bomb. Einstein's seminal works were 'The Basis of the General Theory of Relativity ' 1916 and 'On the Special and the General Theory of Relativity ' 1921 the same year that he received the Nobel Prize in physics. Einstein ranks with Galileo and Newton as one of the greatest conceptual thinkers and revisers of human understanding of the Universe. From the 1930s Einstein became increasingly outspoken in support of world peace and towards the end of his life he devoted himself completely to the establishment of a world government and to the eradication of warfare. One of his last acts was to sign a plea for the renunciation of nuclear weapons. (See ATOM BOMB; CLASSICAL MECHANICS; NEWTON, ISAAC; QUANTUM THEORY, PLANCK, MAX). (IP)

EL NINO-SOUTHERN OSCILLATION PHENOMENON or ENSOP refers to the warm ocean current that blows along the northern tropical coast of South America in its changing phase causing unseasonable changing weather patterns in the Americas and Pacific Region, including Australia. El Nino refers to "the child" of change as opposed to La Nina "the Child" of constancy. Great interest has been expressed in the phenomenon and whether its current greater frequency is linked to global warming and human increases in atmospheric carbon dioxide. One model postulates such a relationship in which trapped heat in the CO 2 -rich atmosphere increases the temperature of the oceans, triggering cycles of drought and rain. The local effects of the El Nino current were known to the ancient people of Peru long before the arrival of the Spanish conquistadores (see SOUTHERN OSCILLATION INDEX & LA NINA -SOUTHERN OSCILLATION PHENOMENON).

ELECTROCONVULSIVE THERAPY (ECT): applying a voltage with surface electrodes across the brain under general anesthesia or muscle-relaxants to prevent muscular convulsions, which can be hazardous. In general, electrical therapy is a valuable medical procedure used by both the radiologist and the psychiatrist, and it can be an important intervention prior to starting stabilizing drug treatment. Cardiologists call their procedures "Cardioversion and Defibrillation" ; psychiatrists call theirs "Electroconvulsive Therapy or ECT" but the two emergency procedures are similar in principle and practice. For example, when the heart muscle beats so fast that it is merely shivering, the heart is said to be fibrillating - a state of increased excitability where the blood ceases to circulate in the body. In this situation a pulse of electricity passing through the heart muscle discharges its electrical potential which stabilized and resets the conducting system of the heart until the muscle begins once more its rhythmic beat. In a mental state of extreme agitation the brains information too fails to flow in logical patterns; thus, a controlled electrical pulse passing across the frontal-temporal region of the brain, hegan in the 1930s as a treatment for severe schizophrenia following the observation that patients with schizophrenia and suffering spontaneous seizeing used as a convenient and quick treatment for manic depression and melancholia. In the United States of America, for example, approximately 80% that 90% of these will show a marked improvement - a significantly higher figure than that from those treated with antidepressant medication. Desputation (described as a barbaric intrusion in Ken Keseys book One Flew Over the Cuckoos Nest which was written before the use of anesthesia). However, scientific criticism of its extensive use is justified because convulsive therapy in inexperienced hands may produce permanent brain damage, especially losses of memory and intelligence. Nowadays, the pulse of electricity in its passage through the brain is monitored by an electroencephalograph, a machine which measures brain-wave activity from electrodes placed on the scalp (see COGNITIVE-BEHAVIORAL THERAPY, LEUKOTOMY).

ELECTROMAGNETIC RADIATION is the Suns ultimate s radiant, anging fromare harnessing this absolute source of energy in original and creative ways. (IP)
ELECTROPHORESIS: A method of separating large molecules (such as DNA fragments or proteins) from a mixture of similar molecules. An electric current is passed through a medium containing the mixture, and each kind of molecule travels through the medium at a different rate, depending on its electrical charge and size. Separation is based on these differences. (DM)
ELEMENT: 1. Elements are the building blocks of chemistry. Elements are the simplest components of molecules that can be produced by normal chemical means. The nucleus of every atom in an element has the same number of protons. Each chemical element contains different atoms to the other elements, and gives off an individual line spectrum. The Periodic Table arranges all of the elements according to their properties. The hundred or so elements combine to create thousands of compounds with the different physical properties that make up the world. (See ATOM, ISOTOPE)

A developing organism in an egg, seed or uterus of its mother. It includes any developing organism before birth, that is derived by fertilization, parthenogenesis, cloning or any other means from one or more human gametes or human diploid cells. Somatic formation of embryo like structures on top of the callus can be grown which can lead to cloned plants from full grown (plant) flower meristem. In human, early or preimplantation embryo refers to the first two weeks after the formation of the zygote. Embryo technically refers to the stage from the third to eighth week of development. Often the term embryo also encompasses development from the beginning up to the eighth week. A specially created embryo can be made by human technology from donor sperm and ovum, under laboratory conditions for research purposes (IVF technology). At times the US government has disallowed funding for embryo research due to ethically and morally contested questions. Source of human embryos include: 1. Elective abortion 2. IVF technology through donor sperm and oocyte of unrelated persons 3. Left over embryos in infertility treatment by couples 4. Cloned embryos. (See FETUS, PRE-EMBRYO). (DM, JA)
EMBRYO DONATION: The transfer from one woman to another of an embryo obtained by artificial insemination and lavage or, more commonly, by IVF.
EMBRYO EXPERIMENT: Why do scientists and doctors carry out experiments on early human embryos? There many aspects to this question but it's important to understand that research and advances in medicine are inseparable. Without research on embryos, for example, the Assisted Reproductive Technologies (ART) would never have been developed and countless infertile couples would not have been helped by modern IVF technology. However, ART procedures are not perfect and to improve their efficacy, further research is required. The area of genetic defects which amount to 2-5% of all births and about half of infant mortality, is another example where responsible embryo research would improve existing understanding of the mechanisms involved in normal and abnormal development.

EMBRYONIC PERIOD : Comprises the first 8 weeks of prenatal life where organogenesis takes place. Organogenesis is the most complex stage of development and is characterized by the formation of all organs and organ systems of the embyonic body. Each organ or organ system has a particular time during pregnancy when it is being formed called the critical period. During the critical period of intrauterine development the embryo or fetus has the greatest sensitivity to environmental influences. Striking advances during the third week is the development of somites, the heart, the neural folds and the major divisions of the brain, the neural crest, and the beginnings of the internal ear and the eye (see also FETOGENIC PERIOD, EMBRYO, FETUS). (IP)
EMBRYONIC STAGE (INTEGRATE!) : A stage in human development between 15 days and 8 weeks post-conception of pregnancy.

The distinction of the can not yet be defined as contributing to the es have been laid down and there is a general appearance of a mammal-to-be with four limbs and a head. (JA)
EMBRYONIC STEM CELLS : (Anglo-Saxon stemm tree or trunk & Latin cella storeroom). A formative cell whose daughter cells give rise to other cell types; for example, pluripotent embryonic stem cells are capable of generating all cell types compared to the multipotent adult-derived stem cells which generate many but not all cell types. Thus, stem cells may originate from embryonic tissue and from adult tissue and both types are suitable for cloning technology; that is, therapeutic and/or reproductive. Therapeutic cloning is the cloning of embryos containing DNA from an individual's own cell to generate a source of embryonic stem cell-progenitor cells that can differentiate into the different cell types of the body. The aim is to produce healthy replacement tissue that would be readily available and due to immunocompatibility, the recipients would not have to take immunosuppressant drugs for the rest of their lives. The ethical status of embryonic stem cells is a matter of controversy because the label embryo is asyo. Folls arts against cloning maintain that by virtue of the pre-embryos special status, its wrong to carry out destructive experiments on them. (See STEM CELL). (IP)

cultured cells obtained by isolation of inner cell mass cells from blastocysts or by isolation of primordial germ cells from a foetus. Embryonic stem cells will not give rise to an embryo if placed in the uterus. (JA)
EMBRYO TRANSFER is the procedure of transferring an in vitro fertilized conceptus into the uterus. The embryos to be transferred are loaded into a fine plastic tube which under ultrasound guidance is introduced via the cervix into the uterus and is, in most clinics, done without anesthesia (see Assisted Reproductive Technologies). (IP)
The appearance of simple large-scale behavior from complexity. Collective behavior is by its nature unpredictable, arising as it does from a complex system of rules and complicated network of subsystems all undergoing change. Emergence is the surfacing of order, from a sea of fluctuations, at a certain scale or level of organization. (See EMERGENT PROPERTIES, SIMPLEXITY, COMPLICITY) (MP)
EMERGENT PROPERTIES: The global properties and behavior of whole systems. Complex systems consist of many interacting subunits which combine to create emergent properties. The inability of reductionism to predict collective behavior is neatly encapsulated by the whole is more than the sum of its parts. Whether or not technically true, the intepossible by collectivity and organization - include economic fluctuations, social order, life, intelligence and consciousness.

EMOTICON: (Emotion + icon) A text-based icon which communicates an emotion, commonly used as a cute form of netiquette in e-mails. For example:
smiley-face :-) wink ;-) laugh :-D frown :-( crying :-(
shock :-o say nothing :-X greedy $-) angel 0:-) devil }:-)
some upright versions, mostly of Japanese origin such as:
glowing smile *^_^* blush @^_^@
and many others. J; (See NETIQUETTE) (MP)
EMOTION: Emotion is the transient psychological, physiological and behavioral response to thoughts, events and social activity. A typical classification of emotions might be the following primary families: anger/annoyance; fear/anxiety; sadness/loneliness; disgust/shame; surprise/shock; pleasure/joy; love/friendship. These feelings arise from neural excitement triggered by perception, cognition or memory. The emotional brain is the limbic system, including its functional compartments: thalamus, hypothalamus, hippocampus, amygdala and pituitary gland. Emotional intelligence is self-awareness and management of ones own emotiTIVISM, MOOD, LIMBIC SYSTEM, AMYGDALA, ANGER, FEAR, PLEASURE, JOY, LOVE) (IP & MP)
EMOTIONAL INTELLIGENCE: A term emphasizing the range of different types of intelligence and the role that emotions play in effective communication and decision making. Emotional intelligence, as Daniel Goleman articulates in his book of the same name, is the most crucial factor in relationship and career success and involves awareness of the appropriateness of emotions we and others use as a guide to our thinking and behaviour. Components of emotional intelligence include the following abilities: self-awareness of ones emotions and their significance, management of ones emotions, awareness of the emotions of others, em both thought and feeling in decision-making, stressersonal connection and effective relationships, conflict resolution, cooperation and communication. (see EMOTIONS, EMPATHY, ALEXITHYMIA) (MP)
EMOTIONAL INTELLIGENCE QUOTIENT (EQ): E.Q. (Emotional intelligence Quotient or Emotional Quotient) is an adaptation of the more commonly known test measure I.Q. (Intelligence Quotient), emphasizing characteristics of emotional intelligence such as ability to read the emotions of others and control ones own emotions accordingly. (See EMOTIONAL INTELLIGENCE) (MP)
: Sometimes emotions are thought of as a better guide to truth and goodness than is the intellect. David Hume (q.v.) said that "the intellect is and ought to be slave of the passions and can pretend to no other office than to serve and obey them." He also argued that ethical statements are really only expressions of how we feel about things. The ethical philosophy of emotivism is one of Hume's heirs. Although it can be debated whether intellect or emotion is a surer guide to truth, they might both be equally determined by education and cultural conditioning. (FL)
EMPATHY: (Greek: empatheia 'affection' or 'feeling into') Empathy refers to an ability to imagine or perceive the emotions or experience of another person. The word was first used in reference to physical or motor mimicry. It requires an emotive psychological identification with another's feelings and identity. Psychopaths and sociopaths may lack the empathy to make this emotional connection. Empathy is the root of compassion. (See SYMPATHY, COMPASSION) (MP)
Derived from observation, experience or experiment rather than from conjecture, hypothesis or theory. Empirical information is based on perception with the five senses rather than thinking and rationalism. (See EMPIRICISM) (MP)
EMPIRICISM: A view or philosophy of knowledge which considers sensory experience to be the primary source of information. Locke, Berkeley and Hume are among the British Empiricists, Kant, James and Wittingstein continued the discussion, and the logical positivists (linguistic empiricism) include A.J. Ayer, Rudolph Carnap, C.W. Morris, Ernest Nagel and Moritz Schlick. (See EMPIRICAL) (MP)
EMPHYSEMA : A lung disease, genetic defect due to lack of a protein, alpha-1-antitrypsin (AAT). (JA)
The provision of power, usually to those seemingly without means of self-protection or control over changes affecting their life. This may include increasing the awareness of indigenous people or minority groups. Without the benefit of an outside perspective it is often difficult to understand the larger-scale system, corporate/government motivations, or avenues of protest, media coverage and/or legal recourse. (See CAPACITY BUILDING, MINORITY GROUPS) (MP)
ENCEPHALIZATION QUOTIENT: Comparative indicator of brain size in relation to body size - for example a species with EQ=1 has an average sized brain for its body size, EQ=2 refers to twice average, dolphins are said to have an EQ of about 5 and humans an EQ of around 7. (MP)
A species that is specific in its occurrence in a particular geographical area. Like the Kangaroo of Australia. (JA)
ENDANGERED SPECIES: A species which is at very high risk of becoming extinct in the wild in the near future. This may be indicated by any of the following measures: a) a previous or projected population reduction of at least 50% over whichever is longer of a period of 10 years or three generations, b) extent of occurrence less than 5000 km 2 or area of occupancy less than 500 km 2 , along with population decline, fragmentation or extreme fluctuations, c) population less than 2500 mature individuals with continuing decline, d) population less than 250 mature individuals, or e) probability of extinction in the wild estimated at 20% over the longer of 20 years or five generations (IUCN Red List Categories 1994). (See CRITICALLY ENDANGERED, VULNERABLE SPECIES, THREATENED SPECIES, GHOST SPECIES, EXTINCTION) (MP)

ENDOCRINOLOGY the study of hormones and their actions (see ENDOCRINE SYSTEM).
ENDOGENOUS: Developing or originating within the organism, or arising from causes within the organism. (DM)
ENDOGENOUS DEPRESSION: Depression arising from within the mind of the individual rather than as a result of external (exogenous) factors or life circumstances. This reflects a genetic predisposition to the disorder, usually involving a physiological imbalance in brain neurotransmitters. Often this results in recurring depressive episodes or chronic major depression, however a predisposition to its expression is not a foregone conclusion with the right lifestyle and environment. Endogenous depression may be managed, with preferably minimal pharmacological treatment, strong social support and a positive, resilient attitude. (See DEPRESSION) (MP)
ENDOMORPH : A person with an extreme body type typified by rounded frame, soft body and plump features such as abdomen larger than thorax. People with a high degree of endomorphy may suffer from difficulty shedding weight, perhaps poor self-image, and increased risk of conditions related to obesity such as heart disease. (See ECTOMORPH, MESOMORPH, OBESITY) (MP)
ENDOTOXIN: Poison produced by some gram-negative bacteria, present in the cellular membrane, and released only upon cell rupture; composed of complex lipopolysaccharide (fat-like molecule and sugar molecule) and more heat-stable than protein exotoxins. (DM)

Kinetic energy (mechanical), potential energy (gravitational), electrical energy, chemical energy (molecular, nuclear), radiant energy (light, electromagnetic radiation) and heat energy. 4. The capacity to cause change in a system; origin of processes, system dynamics. 5. Energy sources: oil, coal, natural gas, ethanol, wind, water, biomass, chemistry, geothermal, nuclear, and the primary energy source for living systems on Earth, the sun. 6.

ENGINEER: (Old French: engignier "to contrive", from Latin: ingenium "talent") The engineer uses materials and processes in the invention, design, planning and construction of systems, products and infrastructure. To engineer is also to originate or cleverly plan an outcome. For the engineer, difficult technical problems must be identified and choices made for the deployment of applied solutions in the face of social and ecological risk and uncertainty. (See ENGINEERING, ENGINEERING ETHICS) (MP)
ENGINEERING: Engineering is the vehicle for the realization of technology. Using information generated from science, engineering oversees the transformation of raw materials into technology. The engineering profession is commonly divided into mechanical, civil, electrical, chemical, aeronautical and military engineering. Such purview indicates the ethical responsibility implicit in this sector and its control over the course of development and change. (See ENGINEER, ENGINEERING ETHICS) (MP)
ENGINEERING ETHICS: Engineers solve problems and build infrastructure within a set of physical, environmental, economic and design constraints. Among those constraints is an ethical duty of care to social and environmental needs. Human and environmental wellbeing are the driving forces rather than individual or commercial desire. Social and ecological requirements are introduced into engineering through regulatory methods like the precautionary principle and environmental impact assessment, and through ethical codes of conduct. Examples of engineering codes of ethics include those of the World Federation of Engineering Organizations, the Institute of Electrical and Electronics Engineers (US) and the Institution of Engineers (Australia). These may include references to fairness, accountability, environmental principles, public protection, and not allowing client interests to compromise community goals. (See ENGINEER, ENGINEERING) (MP)

ENSO : See EL NINO -SOUTHERN OSCILLATION PHENOMENON
ENTREPRENEURSHIP : Investment by health professionals or researchers in a profit-making business or enterprise related to their work (See CONFLICT OF INTEREST). (DM)
ENTROPY: A measure of the disorder or randomness in a system. The second law of thermodynamics states that entropy of a closed system always increases over time. This means that energy is being transformed by the mechanics of the universe into uniformly-distributed heat energy. However, this is true only for large closed systems, and order can be maintained in an open system containing life. (See ENERGY) (MP)
ENVIRONMENT: The sum total of all that surrounds an organism, both biological environment and physio-chemical environment. (JA)
Environmental compensation is a trade-off of beneficial environmental outcomes to compensate for the damage or adverse impacts of development, thus maintaining the aggregate natural stock. Desoals ng industries by establishing programs of tree-planting or trading of carbon credits. (See ENVIRONMENTAL SUBSTITUTION, CARBON CREDITS, BIOREMEDIATION, TREE-PLANTING, RESTORATION ECOLOGY) (MP)
ENVIRONMENTAL DEFENSE FUND: A commendable US coalition of environmental lawyers who forego lucrative careers to rely on public donations in the fight against destructive corporate practices and the support of environmental values in the legal system. (MP)
ENVIRONMENTAL ETHICS : The ethical issues relating to environment. May take anthropocentric, biocentric or ecocentric approaches. Bioethics is a term including both environmental ethics and medical ethics issues. (See BIOETHICS, ENVIRONMENT). (DM)
Movements through compartments of the environment, a model or process. Environmental flows include abiotic solids (e.g. minerals, topsoil), biotic flows (e.g. harvest biomass), ecological flows (e.g. migration), genetic exchange (e.g. crop genetics), water (surface water, ocean currents), air (atmospheric gases), biogeochemical cycles (e.g. carbon, nitrogen cycles), product cycles (extraction, production, transport) and pollution (waste, heat, radioactive materials etc). (See MATERIAL FLOWS, ENVIRONMENTAL PROCESSES, ENVIRONMENTAL SYSTEMS, LIFE CYCLE ASSESSMENT) (MP)
ENVIRONMENTAL GRADIENT: A gradual change in certain environmental conditions. Examples include geographical gradients of climate, soil or vegetation, or abundance/productivity gradients graphed against climate or soil type. Environmental gradients determine the optimal range and distribution of species with different requirements. (See STENOTYPIC SPECIES, EURYTYPIC SPECIES, GRADUALISM) (MP)
Environmental Health : Describes circumstances that ensure that living organisms (plants, animals and microorganisms) are provided with the best chance to reach and maintain their full genetic potential. For example, it is well known that children exposed to harmful agents; such as lead or alcohol, during critical periods in their development, are deprived from reaching their full genetic potential. Obviously the maintenance of overall environmental health is a balancing act between conflicting needs; however, since humans are now 'in charge' of planetary health, we have an ethical duty to do or best in maintaining as fully as possible the genetic potential of all living things. (See WELLBEING; HEALTH; ENVIRONMENTAL ETHICS). (SG2+IP)
ENVIRONMENTAL IMPACT: An environmental impact may be adverse, beneficial or a combination of these, although use of the term often connotes a negative impact. It may be sudden (e.g. land clearing), gradual (e.g. water utilization) or have delayed action (e.g. climate change). Impacts may create secondary or flow-on impacts, and may add or multiply in combination with other impacts. It may be an environmental impact on humans (e.g. natural hazards) or a human impact on the environment (mining, dams, pollution etc). Usually refers to adverse impacts of human activities and developments on natural systems and ecology (e.g. environmental impact assessment), or also on the broader environment including human society (e.g. social impact assessment). Attempts have been made to estimate the total environmental impact of human activity on the Earth; for example,
Total impact = PF (Population
impact per capita)
b) Ecological impact = PCT (Population x Consumption/affluence x Technological efficiency)
c) Impact damage = population x economic intensity x resource intensity x environmental pressure on the resource x susceptibility of the environment
d) Impact = PLOT (Population x Lifestyle x Organization x Technology).
Risk evaluation and prevention of environmental impacts is essential to avoid further breakdown of the Earths ecosystem support processes, critical natural capital and quality of life. (See IMPACT, ENVIRONMENTAL IMPAMENT REPORT) (MP)
ENVIRONMENTAL IMPACT STATEMENT (EIS):
The final document prepared for the Environmental Impact Assessment, outlining the environmental consequences and recommended alternatives or mitigation measures. (See Environmental Impact Assessment) (MP)
ENVIRONMENTAL INFORMATION DIRECTORIES: The proliferation of data collected in recent decades has necessitated information networks and metadata directories to simplify the storage and distribution of environmental information. A few examples include online scientific journals and State of the Environment Reports, national Bureaus of Statistics, United Nations Statistical Division (UNSTAT), Sustainability Web Ring, Center for International Earth Science Information Network (CIESIN), American Library Association Task Force on the Environment, Environmental Resources Information Network (Australia), National Directory of Australian Resources (National Resource Information Centre), World Resources Institute, World Meteorological Organization, Global Change Research Program (US Govt.) and Global Change Master Directory (NASA). (See BIOETHICS INFORMATION DIRECTORIES, MEDICAL INFORMATION DIRECTORIES) (MP) (feel free to add any other major examples)
ENVIRONMENTALISM : The movement concerned with slowing or reversing environmental degradation caused by human activities. (RW)
ENVIRONMENTAL AUDITING: (See ENVIRONMENTAL MONITORING, ENVIRON. IMPACT ASSESS)
ENVIRONMENTAL CODE OF CONDUCT: The integration of an ethical dimension into considerations affecting the environment. This may involve the formulation of new rights, responsibilities and obligations, such as rights of access to environmental information, consultation in environmental decision making, environmental impact assessment, and environmental policy-making which ensures a sustainable quality of life on Earth. (See ENVIRONMENTAL IMPACT ASSESSMENT) (MP+IP)
ENVIRONMENTAL CONSULTING: See CORPORATE ACCOUNTABILITY, ENVIRON. IMPACT ASSESS.
ENVIRONMENTAL EDUCATION: Environmental education is to teach the facts about the environment. It can teach people our relationship to other parts of nature. Environmental ethics education is more. It is to teach how to incorporate the facts and values of different organisms into ethical decision-making. Environmental ethics education teaches how we should live, whereas environmental education is linguistically descriptive, how we do live. However, much of environmental education is actually also teaching some values. But without teaching how to balance all interests, and facts and values, it can be propaganda. (DM)
Ethical issues associated with the environment. Can refer to both living and non-living parts of the environment. Part of Bioethics. (See BIOETHICS). (DM)
ENVIRONMENTAL IMPACT ASSESSMENT : Cl; project like building a high rise dam/a fertilizer chemical plant, it provides useful information for helps decision. Components include: Project concept, pre-feasibility studies, fessibility, design and engineering, implementation, monitoring and evaluation. Principles includevolving the appropriate experts and groups, linking of information obtained with decisions about the proposed projects, presentation of cleaound environmental management. And provision of information in a executive statement for the decision makers.Participants include the develotaff, competent and government authority, local community and politicians. Scope: 1. What will happen as a result of implementing the propos social changes Do the changes matter much? What can be done about them in terms of remedy? How can the decision-makers be informed of what completing the EIA study. (JA)
ENVIRONMENTAL INDICATORS: Physical, chemical, biological, social and economic characteristics of the environment which are monitored as indicators of broader environmental health and integrity. They provide comparisons with standard references, between regions, and of course across time. Environmental indicators create meaning, simplify data and streamline management by reducing the number of measures needed for exact representation of the environmental situation. They represent key states or processes within a well-developed interpretive framework such as Environmental Impact Assessment, Pressure/State/Response models and State of the Environment reporting. As examples, indicators of pressures may include vegetation clearance/fragmentation, indicators of environmental state may include distributions/abundances of species, and indicators of response might include the proportions of protected area by ecosystem type. Environmental indicators may include pre-existing managerial, commercial or census data. Implicit in the choice of a key set of indicators are simplifications, assumptions and value judgments. Care must be taken that they cover all fundamental issues and are appropriately scaled, broadly representative, robust, comparable, credible, and easily monitored. (See INDICATOR SPECIES, PRESSURE/STATE/RESPONSE MODEL, ENVIRONMENTAL MONITORING, ENVIRONMENTAL AUDITING, ADAPTIVE MANAGEMENT) (MP)
ENVIRONMENTAL MONITORING: A process of repeated collection of data from a number of environmental indicators according to schedules across time and space. These are essential for awareness of environmental change and the impacts of policy and development. Choice of measurement parameters is determined by broader frameworks investigating different postulates and processes. Measurement is the authority of science, and neither adaptive management nor credible sustainable development can occur without monitoring. One criticism of the Environmental Impact Statement is its inability to illustrate change, without monitoring we only have static baseline observation. Regularly-used environmental indicators include water quality, species abundance and habitat distribution, but standardized data is also collected by remote sensing and collated by census and State of the Environment reporting. (See ENVIRONMENTAL INDICATORS, BASELINE MONITORING, ADAPTIVE MANAGEMENT, ENVIRONMENTAL AUDITING, ENVIRONMENTAL IMPACT ASSESSMENT, STATE OF THE ENVIRONMENT REPORT, REMOTE SENSING) (MP)
ENVIRONMENTAL PROCESSES: Environmental processes are the functions, forces and dynamics which drive change in environmental systems. Although systems may be diverse and complex, fundamental processes acting upon them are more limited in number and therefore easier to model and manage. Examples of micro-scale environmental processes (with examples of broader application) include the following: chemical transformation and precipitation (e.g. pollution chemistry), biochemical transformation (e.g. metabolic pathways), ion exchange (cellular transfer), genetic exchange (modified crops/ecosystems), adsorption, absorption (biochemical oxygen demand), acid/base reactions (acid rain), sterilization (disinfection), filtration (water quality), coagulation, membrane separations, oxidization/reduction, volatilization (air quality), thermal transformations, phase transfer and mass transfer processes among other transport and transformation processes. The environmental processes category is only one sS, ENVIRONMENTAL FLOWS, PRESSURE/STATE/RESPONSE MODEL) (MP)
ENVIRONMENTAL RESOURCE ECONOMICS : Refers to economic management which goes beyond the conventional supply/demand relationships and monetary values by including other economic aspects of resource usage. Some of these additional aspects include pollution, general environmental degradation, effects on existing life-support systems, and other broadly-based environmentally connected economic concerns. Many aspects of resource utilization consist of intangibles such as culture, knowledge, beauty, ethical insights and general satisfaction with life. These intangibles need to be considered when allocating value to resource development. (IP)
The exchange of one type of resource for another, the usual example being the transition from ecological resources to technological substitutes, usually not until the resource is damaged or depleted. A better proposition is substitution which replaces human economic capital with enhanced natural capital and a stronger environment. Strong sustainability does not allow environmental substitution, and even weak sustainability does not allow substitution of critical natural capital. (See STRONG SUSTAINABILITY, CONSTANT CAPITAL, CRITICAL NATURAL CAPITAL, ENVIRONMENTAL COMPENSATION) (MP)
ENVIRONMENTALLY SUSTAINABLE DEVELOPMENT: Sustainable Development with an emphasis on the integrative inclusion of the whole environment, (not over-emphasizing ecological or economic aspects). (See SUSTAINABLE DEVELOPMENT, ECOLOGICALLY SUSTAINABLE DEVELOPMENT) (MP)
ENVIRONMENTAL SYSTEMS: Environmental systems may be biological, ecological, chemical, physical, socio-economic or managerial. Systems may be natural (e.g. ecosystems), engineered (e.g. urban environment) or artificial (e.g. cyberspace). (See SYSTEM, ECOSYSTEM, ENVIRONMENTAL PROCESSES, ENVIRONMENTAL FLOWS, PRESSURE/STATE/RESPONSE MODEL, SYSTEMS THEORY, COMPLEXITY THEORY) (MP)
(See ECOLOGICAL ECONOMICS, INTRINSIC VALUE, USE VALUE)
ENZYME: A protein that acts as a catalyst, speeding the rate at which a biochemical reaction proceeds by not altering its direction or nature. Also some RNA can act as an enzyme, a ribozyme. Enzymes regulate chemical reactions in cell of an organisms - Most names of enzymes usually end with "ase" eg. Protease. Amylase Exceptions - like Trypsin. (DM, JA)
EPA : Environmental Protection Agency of the USA.
EPC : See EUROPEAN PATENT CONVENTION.
The science of disease incidence and patterns of disease spread and distribution, including disease control and prevention. The study ("ology") of diseases or other phenomena over ("epi") a population ("demos"). The word derives from a book of that name by Hippocrates. Modern epidemiology makes .extensive use of advanced computerized statistical methods. Epidemiology is a powerful tool in evidence-based medicine. But there are always exceptions to every rule. Some few people are sedentary, heavy smokers, and eat all the worst foods, but live long, happy lives. So the value of epidemiology remains incomplete. But today researchers are beginning to pay detailed attention to genetic factors which may explain individual differences and exceptions to rules. This may help epidemiology to become an even more powerful tool.
Bioethical restrictions on study of patients' files and tissue samples, for reasons of privacy, hamper the progress of epidemiological research. While ethical restrictions on interventional and prospective research might be made stricter, more attention might be given to liberalizing restrictions on non-interventional, retrospective research, aided by computerized, anonymized, hospital and health ministry files, opening the way for epidemiology to serve public health even more beneficially. (FL) (See GENETIC EPIDEMIOLOGY)
EPIGENETIC : Different factors can alter the phenotype without modifying the genotype. Imprinting is considered a form of epigenetic modification of the expression of a given genomic region, since the same DNA rearrangement can lead to different phenotypes, depending of the parental origin of the aberrant chromosome. Methylation of suppressor genes in some forms of tumors can also explain modified phenotypes, where no alteration of the genotype is observed. Sibs sharing a same mutated genotype in autosomal dominant or recessive diseases with complete penetrance, but showing a different phenotype, can also result from epigenetic factors acting on the genotype. (See also EPISTATIC). (GK)
EPINEPHRINE : see ADRENALINE.
EPISOME: A DNA molecule that may exist either as an integrated part of a chromosomal DNA molecule of the host or as an independently replicating DNA molecule (plasmid) free of the host chromosome. (DM)
EPISTATIC: Several genes can act on a genotype in modifying its phenotypic expression. This phenomenon has been described for mendelian disorders with complete penetrance, like Cystic Fibrosis, where the same mutated genotypes can have varying degrees of severity of the clinical symptoms. It is presumed that proteins encoded by other genes can modify the original impairment of the CFTR-encoded ion channel. In the case of this disease, epistatic and epigenetic factors, although not yet characterized, are important issues in genetic counseling. (GK)
EPISTEMOLOGY: (Greek: epistemo knowledge) The braf, certainty, doubt, opinion, explanation, interpretation, possibility, skepticism. Sources of knowledge may be sensations, reason, introspection or memory. Epistemology can be considered a theory of knowledge or theory of cognition. Is there an archiettier, Foucault and Pyrrho of Elis. (See KNOWLEDGE, META-KNOWLEDGE, ONTOLOGY) (MP)
Epistemology, or Theory of Knowledge,is the study of how we know, and to what extent we can be sure that our knowledge is true. So epistemology is inseperable from the philosophy and methodology of science. And epistemology of bioethics would be a stu dy of how we can know whether our bioethical opinions are right or wrong. Surely a survey of opinions would not answer the question, because the opinions of a radical reformer might be right, but might be quite unpopular, at least at the beginning. Nor c an be say that we can find out what is bioethically true by looking at religious sources. Although religious sources, like the Bible, might be the inspiration for much deep bioethical thinking, such sources are notoriously unclear about details, and ope n to a variety of interpretations. A good example is the abortion debate within Judaism, where even among the orthodox there is a wide variety of opinions, ranging from the extremely strict to the quite liberal. Since the same sources are available bot h to the strict and to the liberal, we can be sure that the sources do not decide the issue. Utilitarianism (q.v.) was developed by Bentham and Mill as an attempt at an epistemology of ethics. They thought that it would be possible to sit down and calcul a te what act causes the greatest pleasure and the least pain, and is therefore the most ethical.(see the discussion under UTILITARIANISM, ACT AND RULE, in this Dictionary.) Because of the difficulties of developing a scientific method in ethics, emotivis t doctrines (see the discussion under EMOTIONS, EMOTIVISM in this Dictionary) are quite popular. The easiest way to solve the problem is simply to say that words like 'good" and "bad" are simply ways of expressing our feelings about things. So moral sta t ements are neither true nor false, but simply a matter of taste. It is hard to accept this doctrine because it is obvious that statements like "Torturing children is bad" are obviously true. So the search for an epistemology of bioethics is still urgent. ( FL)
Epistemological (or epistemic) is an adjective referring to something with relation to knowledge or belief e.g. an epistemological framework may comprise a certain cognitive stance,

ERGONOMICS: The relation of humans with machines, in particular the study of body posture in relation to engineering. Ergonomics includes features of chair design, tool design, positioning of dials, room layout and computer interface which correspond to healthy body form. For those at a machine, desk or computer for long hours, an ergonomic chair and workplace are essential for preventing stress, fatigue, neck strain, back injuries, deep-vein thrombosis, sprained muscles and repetitive strain injury (RSI). Good posture and movement, correct distance, stretching, work rotation and ergonomic furniture are all healthy aspects of the workplace. (See REPETITIVE STRAIN INJURY) (MP)

EROS: the ancient Greek God of love and sex (known in the west as the winged cherub Cupid). It was believed that Eros participated at the very beginning of creation and from humankinds inception directed and regulated the life and happiness of all. Owing to his multi-faceted characteristics, which effectively recognized the combined elements of loves carnal somatic and psychic dimensions, this God was honored and exalted above any other. It was believed that the communication between the inner psychic and the prols the ideal way of existence in biological terms as it led to the genesis of spiritual goodness and a longing for immortality. (IP)
ERROR : (Latin errare 'to wonder'). In research the uncertainty in a measurement or estimate of a quantity. Uncertainty should be expressed when a temperature, for example, is readable only to the nearest degree Celsius - this temperature should then be documented as 20}0.5_C meaning that the true value lies between 1se from faults/inaccuracies in instruments or changes in conditions can be corrected for. (See ESTIMATE). (IP)
ERYTHROPOIETIN OR EPO: is a naturally occurring hormone produced by the kidneys which stimulates the bone marrow to produce more erythrocytes or red blood cells. Synthetic EPO has gained disrepute because of its illegal use by athletes. The theory behind its popularity is that since red blood cells carry oxygen around the body, hormone-driven increases in cell numbers will also lead to increased oxygen availability and better body performance; for instance, an elite cyclist can travel anywhere between 70-75 km/h but with increased oxygen carrying capacity the rider can potentially reach that speed more quickly and hold it for longer periods. Until recently EPO abuse has been difficult to detect because the synthetic form could not be distinguished from the naturally occurring form. However, technology developed by Australian scientists can now identify biological markers which allow drug-testing authorities to identify the synthetic hormone up to four weeks after the last dose. EPO drug testing was first approved for use in the Sydney Olympic Games in October, 2000. (IP)
ESCHATOLOGY : (Greek: eskhatos 'last') 1. Theology: the branch of religious theory concerned with last things; in particular death, the 'end of the world', and our individual and collective ultimate fate in different religious philosophies. Some traditional 'after-death' circumstances such as divine judgement have been philosophized to occur also on Earth during the lifetime; this is 'realized eschatology'. (See LIFE AFTER DEATH) 2. Science: theoretical physics also contributes towards eschatology, with current cosmological models tending to favor the 'heat death' of the universe over the 'big crunch', depending upon the mass of the mysterious 'dark matter' of the universe. (See BIG CRUNCH, HEAT DEATH, OMEGA POINT THEORY) 3. Strategy and management: the study of logical endpoints and the projection of processes or philosophical models to their ultimate inferred conclusion. Eschatological analysis illuminates the long-term, identifying philosophical directions for problem-solving and decision-making. This can also expose certain ironies inherent in common assumptions about human behavior - for instance, the eschatology of capitalism without regulation or ethical restraint seems to be a final person/company/country with all the fluid capital and an almost total majority with nothing or next-to-nothing. (See VISION, INTEGRATED MANAGEMENT) (MP)
ESD: See ECOLOGICALLY SUSTAINABLE DEVELOPMENT.
ESOTERIC: Typically used to mean 'rarefied and so of little relevance' but originally used with reference to philosophical debates to mean 'meant only for the initiated'. In this sense, an esoteric argument could be difficult to understand but have major consequences. (MR)
ESP: See EXTRASENSORY PERCEPTION.
ESPERANTO : An artificial language designed as a global lingua franca, Esperanto was first published in 1887 by the name 'Lingvo Internacia' by Ludwig Zamenhof under the pseudonym Doktoro Esperanto ('Doctor Hopeful').

ESTUARY: Semi-enclosed coastal waters at the junctions of rivers with ocean habitats, for example littoral basins, bays, inlets and harbours. Estuaries have a high biological productivity due to nutrient delivery and mixing processes. The salinity gradient between the fresh and salt water typically takes the form of a heavier saline wedge, mixed by flood and tidal flows. Major communities in the estuarine habitat may include juvenile fish, benthos, seagrass, mangrove, saltmarsh and wetland ecosystems. Estuaries are essential breeding grounds for many fish species and must be protected from habitat-damaging fishing practices such as trawling. Activities upstream can adversely impact the estuarine environment, for example agricultural runoff which may cause sedimentation and eutrophication.

ETHICAL ANALYSIS : The application of ethical theory to specific moral problems. (DM)
ETHICAL CODES : See CODES OF ETHICS.
ETHICAL INVESTMENT: Financial involvement in ethical companies and sustainable practices which cause no depletion of natural assets or environmental degradation, have no involvement in weapons, uranium, gambling, tobacco or alcohol, and do not infringe the rights of workers, women, indigenous people, children or animals. Many may not agree with or be aware of the ways banks and superannuation funds use community savings to fund corporations with non-sustainable practices. The claim that the market is essentially "amoral" can be countered when knowledge is made explicit of the effects of specific capital flows on the future environment and community. Credit unions, "friendly" societies and local community banks are more consciously managed in the interests of members. Sets of company principles, commercial transparency and consumer watchdogs all facilitate ethical investment. Ethical companies may be involved in alternative energies and sustainable development, or in the creative and information industries where money can be generated without the involvement of natural resources. Appropriate share portfolios can be developed using indexes such as the Domini Social Index (DSI) of US ethical investments, or managed through ethical investment funds like the Australian Ethical Investment Trust. The DSI and other ethical options can outperform the S&P 500 market index. The ethical and environmental sector has the potential to be a boom market as corporations are forced to address their responsibilities towards the planet. Shares in small, well-placed start-up companies dealing with environmental and information technologies generate risky but high returns. Marketing and promotion of ethical or environmental principles can increase consumer interest in a company. Visionary companies motivate with the use of well-defined goals, and sustainable corporations innovate with adaptable working conditions. In the realm of biotechnology companies, the ethics of an investment portfolio may be a matter of opinion. (See SUSTAINABLE CORPORATION, VISIONARY COMPANY, ECOLOGICAL ECONOMICS) (MP)
ETHICAL RELATIVISM : The view that ethical principles vary, or ought to vary, among different groups or cultures. (See CULTURAL PLURALISM). (DM)
ETHICAL REVIEW : Committee review of patient care or research proposals for conformity with ethical guidelines. (See ANIMAL CARE COMMITTEES, ETHICS COMMITTEES). (DM)
ETHICAL THEORY : See ETHICS.
ETHICIST, CLINICAL: A hospital, sick fund, or health management organization employee who participates in ethical decision making in clinical medicine. The employer-employee relationship requires care about potential conflict of interest. Clinical ethicists may be involved only in standard bio-medical issues like DNR (q.v.), truth-telling, coercive treatment, etc., or might be called in to consult on questions of medical negligence, malpractice and the like. In some places, patients and their families are charged for ethics consultations. If the consultation is about withdrawing care from a terminal patient, the family may find themselves in a situation where the patient will not be allowed to die unless an ethicist's fee is paid.
It can be debated whether hospital ethicists are necessary or whether it would be better to encourage physicians and nurses to study ethics deeply and to take more direct responsibility for their decisions. If it is acknowledged that physicians are in the need of someone to observe and criticize their ethics, it can be debated whether the idea of the clinical ethicist is really the best solution, or whether nurses -- who are aware of everything going on in the wards anyway -- should be encouraged to speak out more, and to take more part in clinical ethical decision making. It can also be debated whether those who are learned in bio-medical ethics can make the best contribution by becoming clinical ethicists or whether they might contribute more as educators in medical and nursing schools, teaching physicians and nurses to understand ethical issues more deeply. (FL)
ETHICS: A system of moral principles or standards governing conduct. 1. a system of principles by which human actions and proposals may be judged good or bad, right or wrong; 2. A set of rules or a standard governing the conduct of a particular class of human action or profession; 3. Any set of moral principles or values recognized by a particular religion, belief or philosophy; 4. The principles of right conduct of an individual. Ethical behavior requires the ability to reason, to understand the consequences and to make choices about ones actions. As modern society changes and advances are made in technology, the prevailing ethical standards need to also evolve to incory) [Latin ethicus or Greek ethikos pertaining to "ethos" or character].
Traditional ethics was divided into Substantive ethics or meta ethics. Substantive ethics deals with "what are the rules?" and includes the utilitarian and Kantianism concepts, often both agree on practical applications. In Kantianism actions must subscribe other people as "ends in themselves" and not as means to the ends of others or for self-gratification. In utilitarianism actions on the basis of their anticipated consequences (good actions maximize happiness or minimize unhappiness). (DM, IP, JA)
ETHICS COMMITTEE: Committees established by groups such as professional organizations to consider ethical issues. see INSTITUTIONAL ETHICS COMMITTEE. (DM+FL)
ETHICS-OF-CARE a more encompassing theory of bioethics incorporating the group-point of view; that is, an emotional commitment to, and willingness to act on behalf of persons with whom one has a significant relationship (see ETHICS-OF-RIGHTS). (IP)
ETHICS-OF-RIGHTS is a theory of bioethics which emphasizes the self-awareness point of view; that is, empowered by being informed or care through self-awareness (see ETHICS-OF-CARE). (IP)
ethnic cleansing: The mass expulsion or extermination of people from a minority ethnic or religious group within a certain area and who, in many instances, had lived in harmony for generations prior to the outbreak of national hostilities. Well publicized examples include ethnic atrocities experienced in the former Yugoslavia where the full extent of carnage committed, particularly between Bosnian Serbs and Bosnian Muslims, may never be revealed. War violates fundamental human decency but it is at its worst when actions are taken against the civilian population who then is subjected to atrocities such as rape, assassinations, massacres, torture and ethnic cleansing. (See GENOCIDE; EXTERMINATION; EUGENICS; CRIMES AGAINST HUMANITY; INTERNATIONAL HUMAN RIGHTS LAW; INSTITUTION OF WAR; BIOLOGICAL WARFARE; POST TRAUMATIC STRESS DISORDER). (IP)

"covered", referring to the flower bud operculum). The eucalypts or "gum-trees" are a large genus of over 700 species of trees and shrubs endemic to Australia, making up the vast majority of forest habitat in that country. In addition to
a new genus of eucalypts is now recognized:
which includes the bloodwoods and ghost gums. Eucalypts are commonly cultivated worldwide, and provide valuable hardwood timber as well as eucalyptus oil used as a germicide and expectorant. (See SCLEROPHYLL FOREST) (MP)

EUGENICS: Attempts to improve hereditary qualities through selective breeding. See positive eugenics, negative eugenics, eugenics of normalcy . Eugenics is defined " as any effort to interfere with individuals" procreative choices in order to attain a societal goal ". Word means " good breeding " from the Greek names Eugene and Eugenia expressing the notion of "well born" which was a celebration of parents belief that their offspring are especially blessed. The term was coined by Sir Francis Galton, an English scidea has been abused in the past; for example, by the Nazis in the 1930s and early 1940s, and some countries havern eugenics is based on eliminating genetic disorders. (See ETHNIC CLEANSING) (DM+IP)
EUGENICS OF NORMALCY: Policies and programs intended to ensure that each individual has at least a minimum number of normal genes. (IP)
EUPHEMISM: (Greek: euphemismos "good speech") Terminology or language which puts a favorable connotation on a sensitive word. Early euphemisms probably arose as discreet references to revered deities. The use of euphemism for political, medical and sexual concepts flowered in the decorous and dignified language of Renaissance and Victorian aristocracy. These courtly circumlocutions were described as "euphuism" by John Lyly in his 1578 satire Euphues . Euphemisms may be created by widening concepts, semantic shifts, metaphor or phonetic distortion. Euphemism provides the useful bioethical function of avoiding offense and reducing unpleasant psychological associations from fearful or grievous situations such as death. However, euphemisms are also employed in deceit and propaganda to obscure embarrassing concepts and practices in politics (e.g. peoples dem, freedom fighter, peace enforcement, pre-emptive strike and preventive war).

A species which has a large tolerance to environmental change, typically with a wide geographical distribution. (See STENOTYPIC SPECIES, ENVIRONMENTAL GRADIENT) (MP)
EUSTRESS : Happy stress from the Greek eu meaning happy or well. In biology stress is essentially reflected in the total rate of all the wear and tear caused by life and, although it is impossible to avoid stress, a lot can be learnt about how to keep its damaging side effects to a minimum. Stress is personal - envigorating for some, devastating for others; thus, the stress experienced depends not so much on what we do or what happens but on the way we take it. Characteristics such as self-confidence, reliance, trust, esteem and a flexible motivation springing from an inner strength all lower distress and heighten eustress. Additionally, eustress increases productivity and learning, whereas prolonged distress has the opposite effect. (See DISTRESS; STRESS; GENERAL ADAPTATION SYNDROME). (IP)

EUTROPHICATION: (Greek eu well + trephein to flourish). The addition of nutrient material, mostly from domestic sewage, some industrial wastes and the leaching of fertilizers from agricultural lands, into rivers and lakes with the subsequent flourishing of algae and microorganisms. This results in the depletion of dissolved oxygen and the potential suffocation of other aquatic organisms (see ALGAL BLOOMS). (MP & IP)

EVENT HORIZON : The event horizon, or 'Schwarzchild radius', refers to the gravitational 'point of no return' surrounding a black hole. Beyond this point matter and light are captured by the black hole, preventing the possibility of any return or communication back across the event horizon. (See BLACK HOLE, IRREVERSIBLE DAMAGE) (MP)
EVIDENCE: Expert knowledge, information or data which supports an assertion or hypothesis. (See EVIDENCE-BASED MANAGEMENT, VALIDATION, EMPIRICAL) (MP)
EVIDENCE-BASED MANAGEMENT: The use of existing data and on-going monitoring of indicators to determine the most appropriate management strategies. In practice this may mean that environmental management should have stronger links to scientific recommendations than to political whims. If the best available information is inadequate, the precautionary principle should be considered and action should not be taken/delayed while waiting for better evidence. (See ADAPTIVE MANAGEMENT, BEST AVAILABLE INFORMATION, BEST CURRENT PRACTICE, PRECAUTIONARY PRINCIPLE, ENVIRONMENTAL MONITORING, ENVIRONMENTAL INDICATORS). (MP)
The ancient religion of Manichaeism taught that the world derives from two principles, the Principle of Good and the Principle of Evil, which are always in conflict with one another. Christianity, holding that God is entirely good, and has created everything, had to deny the real existence of evil, and to reject Manichaeism as a heresy. Christian philosophers attempted to explain the apparent existence of evil in the world by saying that evil does not really exist, but is only the
, or lack of good. A lie, therefore, is only a falling-short of honesty. Meanness is only a falling-short of generosity. Cowardice is only a falling-short of courage. And gluttony is only a falling-short of self control. This doctrine has much to recommend it in terms of its value in encouraging a charitable attitude towards others. Rather than harping upon the faults of others, let's not look at their lacks, but at their positive qualities.
This doctrine, however, seems to be at its best when it is a question of the rather minor faults and errors of our friends and neighbors, and of ourselves: where it is good advice to overlook the sins and focus on the virtues. But what about a terrorist leader, who plays on the religious faith of some poor fool, indoctrinates him with venom, dopes him up, and with metaphysical promises gets him to go blow himself up in a bus full of simple working people and schoolchildren? Should we ignore the evil of this act and focus instead charitably upon the virtues of the terrorist leader, such as that he pays his debts in time and brings his wife flowers regularly?
Unlike Manichaeism, Judaism does not recognize evil as a principle equal in power to good. But unlike Christianity, Judaism does not deny the real existence of evil. Nor does Judaism have any article of faith according to which God is all perfect and incapable of doing evil. Indeed when God threatened to kill all of Sedom, Avraham found this ethically abhorrent and argued: "Shall not the Judge of all the earth do right?" (Genesis XVIII, 25) Judaism believes that God creates both good and evil, and commands us to bless God for both. We do not, however, know God's reasons for anything, including God's reasons for creating evil. We can guess that God perhaps creates evil in order to put us through experiences which will help strengthen and improve our souls, an idea which fits in well with the doctrine of reincarnation. But this is only a guess. God's real reasons for doing anything (if God indeed has reasons in any sense of the word "reason" which we can understand) are mysteries which are for God, and not for us, to know. (FL)
EVOLUTION: 1. Any series of gradual or punctuated changes through time. 2. In biology, the continuous genetic adaptation of species to environmental change by the agencies of natural selection, hybridization, inbreeding and mutation. The theory of evolution by natural selection was first popularized by British naturalist Charles Darwin in The Origin of Species (1859) and has since been supported by scientific research such as breeding experiments.

Allocation of value to ecosystems and the natural environment as a reflection of human desire for their continued existence - despite no expectation of actual contact or use of the resource. Although less selfish than values derived from direct use, existence value is still slightly anthropocentric in that it reflects human sympathy and preferences rather than any naturally inherent intrinsic value.

(See CONTROL GROUPS, DOUBLE BLIND EXPERIMENT) (MP)
"known by experience") Experts possess detailed current knowledge and an ability to process complex information. Their expertise may derive from proficiency in specialised skills, depth or range of knowledge, or decisive wisdom in judgement. Critics maintain that expertise from a single professional field poorly equips the specialist for problems in a broad, interconnected and complex world. Narrower specialised knowledge should be supplemented by higher order knowledge of the context, for example interrelated concepts, spatiotemporal relationships and processes of change. Experts have a privileged position of community trust as sources of knowledge, and this implies professional ethical responsibility in the gathering, distribution and use of this knowledge for decision making. (See EXPERTISE, EXPERT SYSTEM) (MP)
EXPERT SYSTEM: Expert systems and decision support systems are software which mimic the inductive or deductive reasoning of a human expert. Complex problems such as diagnosis, prediction, interpretation, planning and design are modelled and solved using inferences from facts and rules derived from expert knowledge. Expert systems may be defined by their task specialization and performance, problem solving ability in a given domain, ability to reformulate a problem, efficiency, complexity or symbol manipulation. Such software is the practical application of artificial intelligence research. Expert systems for management advisory and executive decision support have been deployed in industries such as medical diagnosis, mineral prospecting, military planning, engineering and finance. (See ARTIFICIAL INTELLIGENCE, EXPERT, EXPERTISE) (MP)
EXPERT SYSTEM SHELL: Software containing the basic non-specialized components of an expert system such as the inference mechanisms and user interface, but not including the specialized knowledge base. The addition of expert knowledge to this shell creates a new expert system specialized for a specific domain. (See EXPERT SYSTEM) (MP)
EXPERT TESTIMONY : The presentation of pertinent information by a qualified specialist before a court or governmental body. (DM)
EXPERTISE: Expertise is usually defined by scope of detailed current knowledge and range of experience within a professional field or fields. It may also be expressed as proficient ability with a skilled task and familiarity with its performance. Other characteristics commonly regarded as comprising expertise include a combination of the following: high level attention, perception, concentration, cognitive processing and analytical intelligence, knowledge of context and complexity, understanding of fundamental patterns and processes, ability to understand abstract concepts, intellectual confidence in decision making, creative ability with ideas and concepts, selectivity regarding the relevance of information, adaptability to change, strong co-operation and communication skills, credibility of reputation, and a strong sense of professional ethical responsibility for choices made. (See EXPERT, EXPERT SYSTEM) (MP)
EXPONENTIAL: Something grows exponentially, i.e. geometrically, if it increases (or decreases) by a constant factor with each unit of time. For example, the value of money decreases exponentially with time if the inflation rate remains constant. For much of human history, world population size has been increasing exponentially or even at a great than exponential rate. This cannot continue for many more decades. (MR)
EXPLOITATION : 1. Taking unjust advantage of another or utilize a person for ones own profit or benefit 2. utilization by application of industry, argument or other means, as the taking advantage of a mine or an old-growth forest. (IP)
EXPLORATORY RESEARCH: Initial broad investigations, such as baseline monitoring or pilot studies to determine the nature of the subject and priority problems for research. (See PILOT STUDY, RESEARCH AND DEVELOPMENT) (MP)
: Substances such as gunpowder, cordite, nitroglycerine and TNT which decay rapidly under certain conditions, causing sudden violent expansion with a shock-wave of kinetic energy, sound, light and heat. Explosives are the basis for most modern weapon and rocket systems, from the handgun to the nuclear bomb. The primary purpose of explosives in warfare is the destruction of people and infrastructure. The purpose, precision and effectiveness of this task are obviously matters of bioethical concern. Factors influencing the consequences of the use of explosives include type of weapon, impact precision, burst specifics, explosive yield, lethal radius, ground characteristics and target density. (See EXPLOSIVE YIELD, TNT, BALLISTICS, MISSILES, LAND MINES, NUCLEAR WEAPONS) (MP)
EXPLOSIVE YIELD : The strength of explosive energy contained within a bomb or nuclear warhead, expressed as the equivalent tonnage of TNT required to produce the same explosion (one ton of TNT releases about 106 calories of energy). For example the 20 kiloton atom bombs dropped on Hiroshima and Nagasaki had an explosive yield equivalent to 20,000 tons of TNT. Other nuclear weapons have been tested with explosive yields up to 70 megatons. (See EXPLOSIVES, TNT, NUCLEAR WEAPONS) (MP)
EXPRESSED SEQUENCE TAG : A segment of DNA corresponding (can be used as a tag) to turned on genes in a particular tissue/organism. (JA)
EXTENT OF OCCURRENCE: See POPULATION DISTRIBUTION.
EXTERMINATION : 1. The complete destruction of a population or community of living organisms, for example pests or vermin. (See EXTINCTION) 2. Intentional infliction of insufferable conditions for life (e.g. prevention of access to water, food, medicine or safety) with the intent of destroying some segment of a population. (See GENOCIDE, CRIMES AGAINST HUMANITY, ETHNIC CLEANSING) (MP)
EXTERNALITIES: Variables affecting human welfare which are impacted by economic processes, but not calculated or recompensated in economic terms. The generators of externalities and those benefited/impacted would be taxed or subsidized accordingly in a broadly sustainable system. Various categories of externalities include pareto-relevant, pecuniary, technological, private/public goods, socio-cultural amenities, pollution and natural resource values. In the interests of economic efficiency corporations/governments often dont factor in these external costs, to the detriment of society and the environment. (See OPPORTUNITY COST, EFFICIENCY, ENVIRONMENTAL ECONOMICS) (MP)
No longer existing in living form as a species, having died out as a result of the normal dynamic of evolution or commonly also due to human disturbances such as habitat destruction. Current programs to store and perhaps restore frozen DNA of extinct species are commendable only if they take no pressure off efforts at conservation of the living organisms; after all we aren"t able to recreate the most significant units of nature, complex ecosystems. (See EXTINCTION, ENDANGERED SPECIES) (MP)
EXTINCT IN THE WILD: A taxon which has not been recorded in expected habitat over an appropriate time frame throughout its past range. Such species may survive only in captivity, cultivation or as a naturalised population away from its original wild habitat. (See ENDANGERED SPECIES, GHOST SPECIES, EXTINCTION) (MP)
EXTINCTION: Extinction is the termination or extinguishing from the Earth of an evolutionary lineage such that they no longer exist in living form. Anything which ceases to exist can also be said to undergo extinction, such as outmoded technology, information, beliefs or behaviours. In psychology and physiology, extinction is a decline in a learned or stimulus response in the absence of reinforcement. Extinction however most often refers to the loss of a group of organisms, usually a species but ranging from a local population to a phylum. We are currently experiencing a human-driven mass extinction, and extrapolations from current trends predict the rapid extinction of approximately half of the species on Earth. This mass extinction is the result of rapidly expanding human populations and our excessive focus on economic growth, with the associated development, pollution, hunting, pest introductions, land degradation, habitat destruction and ecosystem fragmentation. This massive loss of life will have serious global repercussions for the future of natural biodiversity, ecosystem processes, habitat stability and other essential ecological functions. Even from a purely anthropocentric point of view which ignores the intrinsic value of nature, this mass extinction is resulting in rapid loss of information and ideas, new patterns and processes, chemical and food products, and other economic, aesthetic and spiritual opportunity costs. Perhaps the greatest danger from this extinction of biodiversity is the risk of undermining the stability and homeostasis of the Earths self-sustaining feedback mechanisms, possibly resulting in a world uninhabitable to humans. (See EXTINCT, MASS EXTINCTION, HUMAN EXTINCTION). (MP)
EXTRACHROMOSOMAL DNA: DNA not associated with the chromosome(s), for example, plasmid DNA or organelle (mitochondria or chloroplast) DNA).
EXTRAORDINARY TREATMENT : Therapeutic measures which cannot be obtained without excessive expense, pain, or other burden, or which, if used, would not offer a reasonable hope of benefit. (See FUTILITY). (DM)
EXTRASENSORY PERCEPTION (ESP): The alleged ability to perceive or receive information from beyond the natural range of the five senses. ESP takes various forms, including alleged awareness over a distance of events (clairvoyance), thoughts (telepathy) or feelings (telesthesia), sometimes ahead of time (precognition). Biotechnology such as cybernetic connections between neurons and microprocessors in combination with wireless internet technology or virtual reality may in the future potentially allow the simulation of some of these forms of ESP involving distance. (See CLAIRVOYANCE, PRECOGNITION, PSYCHOKINESIS, TELEPATHY, TELESTHESIA) (MP)
Blood clotting elements are know as Factor V III and IX. They are extracted from a collection of blood samples. It is important that hemophiliacs do not receive contaminated blood. (JA)
FACTORY FARMING: Production of meat or other animal products under industrial conditions. Although there are situations in which the industrialisation of animal husbandry can have animal welfare benefits - e.g. the practice of bringing lambs indoors after birth - the general consequences for animal welfare have been negative. Factory farming only became widespread and significant during the second half of the twentieth century. It helped to lead to large falls in the cost of animal products but has increasingly been criticised on bioethical grounds. Some countries are now, slowly, legislating against certain factory farm practices, such as excessive overcrowding and the prophylactic use of antibiotics. (MR)
FAHRENHEIT (°F) : (German physicist Daniel Fahrenheit 1686-1736). A scale of temperature in which the freezing point of water is 32 ° F and the boiling point is 212 ° F at one atmosphere of pressure. (See CELCIUS DEGREE, TEMPERATURE) (IP)
FAITH: Usually thought of as a belief which is not founded upon experience, scientific evidence, or deductive reasoning (q.v.). The idea of faith is strong in Christianity. Although it exists in Judaism, it is not clear how much of the idea is original to Israeli sources, and how much is adopted from Christianity. Epistemologically, it is extremely difficult to distinguish between faith, indoctrination and emotional enthusiasm. It should be discussed whether a deep inner calmness may serve us more strongly in times of need, than can religious faith. (FL)
FALLACY: 1. In philosophy, a fallacy is a logical breach or fault in an argument. A logical or formal fallacy is an invalid argument in which the premises do not deductively imply the conclusion. 2. More broadly, a belief which, although it may be widespread in the community, happens to be wrong. (See FALSIFICATION, PROOF, LIES) (MP)
FALLOPIAN TUBE: Either of a pair of tubes that conduct the egg from the ovary to the uterus. Fertilization normally occurs within this structure. Blocked or scarred fallopian tubes are a leading source of infertility in women. (IP)
FALSIFICATION: Outside of philosophy, to falsify may mean to fake evidence for a theory, but more technically in the philosophy of science, falsification is the process of showing a theory or hypothesis to be false. This method, emphasized by Karl Popper in his Logic of Scientific Discovery , is one of the most powerful determinants of probable truth. The process begins with a hypothesis, the opposite of which is thus the null hypothesis, which is then attempted to be experimentally disproved. This experimental rejection of the null hypothesis is indirect proof which lends support to the hypothesis, but does not ultimately prove it. Because of the difficulties of confirmation and ultimate proof, the critical method of falsification is the primary process at work in the advancement of science. (See SCIENTIFIC METHOD, EMPIRICISM, HYPOTHESIS, PROOF) (MP)
FAMILIAL DISAUTONOMY (FAMILIAL DISAUTONOMIA)
: An autosomal recessively inherited disease, most commonly seen in Ashkenazi Jewish children. It was first described by Reily and Day in 1949, and in 1993 the responsible gene was located somewhere on chromosome 9, a fact which makes it possible to identify the carriers but not the diseased fetus. Patients with FD suffer from autonomic neuropathy affecting the glossopharyngeal or vagus nerves, baroreceptor response and other sensory and motor neuropathies. Orthostatic hypotension is the most disabling aspect of FD, others include disturbances of sweating, salivation, and swollowing. Treatment consists of symptomatic and preventive measures including medication, physiotherapy, behavioral, and family treatment. The ethical aproach for Familial Dysautonomy is a paradigm for most of the genetic diseases and includes different issues: 1.genetic screening. One must decide if it preferableto screen the whole population in Israel or just Ashkenazi Jews or just families with known members with FD who want to have children. 2.If one tests positive for FD during pregnancy, the physician must decide whether to recommend an abortion without knowing if the fetus is a carrier or a diseased child. In religious families, can we recommend an abortion without knowing the attitude of the patient`s spiritual guide towards abortions and even the discussion may cause the family anguish and perhaps shame and guilt feelings? 3. When there is a child born with FD who needs an expensive treatment, should a state, or state subsidized, health service pay for it at the expense of treatment for other diseases or should the cost be shared with the family? Should the state also have to pay for complementary medicine including herbal and oriental medicine, which in certain cases can help relieve some of the symptoms although it is not evidence based medicine? Other ethical aspects concern the medical staff: doctors, nurses, physiotherapists etc. who needs to maintain neutrality even if they object to abortions. If they make recommendations, and the family does not cooperate, they still must relate to the family and continue the treatment with intensity and compassion. There are many open questions and some of the answers depend on cultural, behavioral and religious opinions of families, medical staff and the public. (AZ)
FAMILY 1. any group of persons closely related by blood or choice like parents and their children including adopted 2. all those descended from a common progenitor 3. in biology the major subdivision of an order or suborder, commonly comprising several generations. (GK)
EXTENDED FAMILY In many developing countries, the family unit includes grandparents, aunts and uncles and even more distant family members that might live together in a common house and exert parenthood towards small children. Conversely, adults take care of their parents until death, taking over the costs of an extended household in these types of families. (GK)
NUCLEAR FAMILY Indicates the family made up of father, mother and children (biological or adopted). Many laws in developing countries, especially catholic, legislate for housing, subsidies, etc, for the nuclear family, ignoring the complex reality of different sorts of family units. Moreover, many of these laws recognize the father as the head of the nuclear family, whereas a great amount of these are fatherless families, where the mother is the head, but without prerogatives face to the law. (GK)
UNIPARENTAL FAMILY : A family made up of only one of both parents and its children. Today, in most uniparental families the parent who is missing is the father. Most of these families are to be found in third world countries, where their occurrence is the result of a fatal incident: in many cases the father is missing because he has abandoned his family, in others because he has been killed during war or violence bursts of different sources. Single women can also decide to have children, in which case the uniparental family is the result of a choice. (GK)
FAMILY PLANNING : Programs or services designed to help people avoid unwanted births or control the interval between pregnancies. (See Natural Family Planning Methods , CONTRACEPTION, POPULATION CONTROL). (DM)
FAMILY PRACTICE : The branch of medicine concerned with the provision of continuing, comprehensive health care for the entire family. (See GENERAL PRACTICE). (DM)
FAMINE: Famine is widespread risk of death by starvation and malnutrition; a devastating condition of insufficient food supply, usually combined with shortages of water and medicine. Famine affected countries have included Ethiopia, Somalia, Iraq, Afghanistan and North Korea, exacerbated by drought, political mismanagement or conditions of war. Emergency food aid should be deployed efficiently and independently of any economic sanctions or political concerns. (See FOOD AID, FOOD CRISIS, MALNUTRITION) (MP)

FAQIH : From Arabic root, f.q.h. literally means a scientist, well-informed, clever. In the Islamic society Faqih is a person who is an Islamic scholar to teaches and guides to Islamic faith. Who spends years of study in Islamic law, jurisprudence, philosophy, ethics as well as being engaged in self-purification.Muslims can refer to him in order to find the answer for their religious questions. (AB)
FAS: See FETAL ALCOHOL SYNDROME .
FASTING : Abstaining from food (and drink). This practice is found in many of the world's religions and traditions. In some cases, the abstention is total, as in Jewish fasts, and the Muslim fast of Ramadan, and in other cases, the abstention is in limiting the range of foods eaten, as in some Buddhist and Hindu traditions. Generally, when the abstention is total, the time limit is sunrise to sunset, or 24 hours. If the abstention is partial, the duration of the fast may be a number of weeks, depending on the tradition. (AG)
FATWA : (Arabic fată 'to instruct by a legal decision'). A generic term for any legal decision made by a Mufti or other Islamic religious authority. The term acquired familiarity in the West when in 1989 Iran's Ayatollah Khomeini issued a fatwa sentencing the British writer Salman Rushdie to death for publishing The Satanic Verses which was considered by many Muslims as blasphemous and extraordinarily offensive. The word, however, does not necessarily mean a death sentence. (IP)

FEAR : 1. (Middle English fer 'danger') the feeling of anxiety related to an identified source threatening potential personal harm or safety of another; apprehension of approaching danger 2. state of alarm generated by the neuroendocrine response to threat causing muscular and psychological tension that interferes with the normal processes of living. (See ADRENALINE; GENERAL ADAPTATION SYNDROME; FIGHT OR FLIGHT RESPONSE). (IP)
FEEBLE-MINDED : Little used pejorative term referring to arrested or incomplete development of the mind, including subnormality of intelligence ranging from slight to severe. Other outdated disparaging terms in this category are 'idiots', 'imbeciles' and 'mongols' that describe individuals having an IQ between 50 and 69. (See INTELLIGENCE, INTELLIGENCE QUOTIENT, FETAL ALCOHOL SYNDROME, AUTISM, DOWN'S SYNDROME). (IP)
Feedback is the flow of changes through a system which come back in a circle to again affect the initial cause of the change. This feedback loop is a continuous re-iterative cause-and-effect relationship between interactive elements and adjusting subsystems. Positive feedback reinforces the original process and negative feedback suppresses the original process. Automatic feedback control and cybernetics are important to adaptive intelligence in both humans and machines. Reinforcing feedback increasingly alters the system away from its initial point as each change amplifies the next (e.g. population growth, epidemics, cancer, debts, self-advancement). Balancing feedback dampens the effecloquially, a negatlth and relationships. (See FEEDFORWARD, CYBERNETICS, SYSTEMS THEORY, SYSTEM DYNAMICS, COMPLEXITY THEORY, CATALYST, THRESHOLD, POSITIVITY) (MP)
FEEDFORWARD: A sort-of positive balancing feedback, feedforward drives a sITY) (MP)
FEMALE : 1. Organisms whose reproductive organs produce only female gametes; that is, eggs in animals or ovules in fruit-bearing plants. 2. may also be used as a derogative metaphor suggestive of 'weakness' or 'inferiority'. (See MALE; FEMINISM). (IP)
is a relatively new barrier method of contraception which is female-based, gives protection against sexually-transmitted diseases including AIDS, and is not dependent on male erection and intromission. The Femshield consists of a polyurethane vaginal sheath lining the whole vaginal surface, is stronger and lighter than the latex rubber used in male condoms, easy to insert and is used in conjunction with a lubricant. Women find it very effective being attracted to their control of contraception and protection against disease (see CONDOM). (IP)
FEMSHIELD: see FEMALE CONDOM.
FEMALE GENITAL MUTILATION is an ancient practice which is said to predate most modern religions, including Christianity and Islam on account of its not being mentioned anywhere in the Quran or the Hadith collection of Al-Bukhari; that is the collections of traditions about Muhammad and his companions. The practice as it endures today covers a graded series of alterations to the female genitalia, ranging from mild to most severe. "Sunna" or circumcision is the mildest form where the hood of the clitoris is removed only; clitorectomy involves the removal of the entire clitoris as well as the labia minora; infibulation involves the removal of the clitoris, labia minora, labia majora and parts of the vulva. After infibulation, the remaining tissue mass is sewn together with catgut or held together with thorns, leaving a tiny hole for urine and menstrual blood to pass through. Deinfibulation and reinfibulation occurs when it is decided that the woman should conceive and give birth. Genital mutilations cause local infections, generalized septicemia, life-long problems with urination and menstruation, chronic pain, suffering and death and is an extreme example of abuse resulting from culturally-driven control of female sexuality. Worldwide, it is estimated that 130 million girls and women, mostly African, have been affected by the practice and that a further 2 million are at risk every year. (IP+AG)
FEMICIDE : The killing of a woman, one who kills a woman. (See FETICIDE). (IP)
: A contemptuous blended term for a radical feminist. The use of the word was originally associated, in the early 1990s, with the abortion debate and was applied to women who supported the pro-choice movement. The term has now spread outside the abortion issue into general use. (See FEMINISM). (IP)
FEMINISM (FEMINIST MOVEMENT) : A widespread and extremely influential movement by women against male-dominated society. Feminists demand abolition of the double standard, removal of traditional stereotypes representing women as fragile, dependent and passive, equal pay for equal work and the right to social and sexual equality. (See FEMINAZI). (IP)
FERMENTATION: The process of growing microorganisms.
FERTILITY : The ability to reproduce. In women days 10-18 from the beginning of the menstrual period are considered the days of highest fertility. Fertility is the ability to produce a offspring or a progeny. Many factors are known to impair fertility such as environmental mimics of estrogen due to the use of chemical fertilizers, plastics, chemicals used during pregnancy. (See INFERTILITY; FERTILITY RATE). (IP,JA)
FERTILITY DRUGS: Compounds used to treat ovulatory dysfunction. These include clomiphene citrate, human gonadotropins, bromocriptine, glucocorticoids and progesterone. (IP)
FERTILITY RATE : The number of pregnancies per year per 1,000 women of childbearing age. (See FERTILITY; INFERTILITY). (IP)
FETAL ALCOHOL SYNDROME (FAS): a set of congenital psychological, behavioral and physical abnormalities in infants whose mothers consumed alcohol during pregnancy. The syndrome was first reported in 1968 by the French pediatrician Lemoine and his colleagues who described a distinct pattern of anomalies in babies born to families with a history of chronic alcoholism. The anomalies included growth deficiency, reduced brain size (microcephaly), a cluster of anomalous facial characteristics, cardiac defects, limb deformities, central nervous system dysfunctions resulting in attention-deficit hyperactivity disorder, delays in psychomotor and language development, poor visual memory and psychosocial maladjustment. The IQ of the children described was about 70; however, the severity of mental and physical disability is related to the degree of alcohol exposure in utero and to varying genetic susceptibilities in the fetus. Of all the characteristics of FAS, mental disability is the most damaging and consistent consequence, and alcohol is now the leading cause of intellectual disability in the western world, followed by Downs syndrome and cerebral palsy. The detrimental consequenc children and the consumption of alcoholic beverages by young married couples was prohibited in ancient Greek and old testament writings. (IP)
FETAL REDUCTION : The deliberate therapeutic removal of one or two fetuses following the diagnosis of a multiple pregnancy. Multiple pregnancy is not solely a specific risk of in vitro fertilization treatments, where two or three-embryo transfers are permissible, but also because the incidence of multiple births has been steadily increasing in all developed countries since the early 1980s. Preterm delivery and low birth weight are the main causes of increased morbidity and mortality in the neonatal period. The average duration of pregnancy is 38 weeks for singletons, 37 weeks for twins, 33.5 weeks for triplets and 31.5 weeks for quads. Parents of multiple-birth children face not only a significant higher risk of one of their children having a disability but a further specific risk owing to the fact that compared to singletons, there is a 3-7 fold higher incidence of cerebral palsy in twins and over ten-fold higher incidence in triplets. The perinatal mortality rate in twins is nearly five times higher than in singletons and in triplets eight times higher. The main contributor to the high morbidity and death rate in multiple births is prematurity and its complications. It is easy to see that for some couples faced with the risk of death or disability to one or more of their children, a fetal reduction may seem the best option; but this is not an easy or uncontroversial solution as it too carries its own risk of medical and emotional complications. (See INTRAUTERINE GROWTH RETARDATION; PREMATURITY; SUDDEN INFANT DEATH SYNDROME). (IP)
FETAL GERM CELLS (FG)
: Germ cells of fetal origin. (JA)
FETAL THERAPY : In utero therapy. (DM)
FETOGENIC PERIOD : In humans lasts from week 9 to birth where important developments are general body growth, histological and functional development of organs and the histological development of the central nervous system (CNS). Approximately 38 weeks post-conception in humans (40 weeks post=last menstrual period). Brain development, however, occurs during the entire period of fetal differentiation and through the first 2 years of postnatal life. Drug abuse during gametogenic, embryonic and fetogenic periods may harm normal growth and development in the offspring and increase its changes of being born with birth defects, low birthweight, and mental/behavioral deficits (see embryonic period, teratology, embryo and fetus). (IP)

FINGERPRINTING: The technique of DNA fingerprinting is used to uniquely characterize individual organisms, foods, or biological samples, based on their DNA composition (can also fingerprint chemicals and proteins). (DM+GK)
FIQH: The science of Muslim religious law or Islamic jurisprudence. The first scholar to write a treatise on Fiqh was Shafi'i (d. 820). Four main schools of Muslim law have survived to modern times among the Sunni. These are: Hanafi, Hanbali, Maliki and Shafi'i. Each of these is regarded as equally valid by Orthodox Muslims. The Shi'i have their own systems of Muslim law. (AG)

FIRST WORLD: Slightly condescending term for the developed nations, or wealthy North. The first world includes Europe, North America, Japan, Australia and New Zealand, and sometimes including industrialized countries like Singapore and Taiwan, democratic states like Israel and South Africa, and/or emerging capitalist economies such as Russia. The wisdom of being first depends on whats ahead and what you leave in your wake. In many respects the First World may be over developed, requiring demilitarization, dematerialization and more responsible ethical standards for custody of the global environment. (See FOURTH WORLD, THIRD WORLD, SECOND WORLD, NORTH, DEVELOPMENT, DEVELOPED NATIONS, OVERDEVELOPED NATIONS, ENVIRONMENTAL CODE OF CONDUCT, DEMILITARIZATION, DEMATERIALIZATION) (MP)

FISHING PRACTICES: (See COASTAL ZONE MANAGEMENT)
FISHING QUOTA : The fishing or vessel quota is a sustainable fisheries management method for allocating fishery property rights and sharing the 'total allowable catch' among rightful fishing parties. Fishing quotas may be transferable, seasonal, area-specific, species-specific and/or enforceable by law. (See QUOTA, TOTAL ALLOWABLE CATCH, THRESHOLD MANAGEMENT) (MP)
FIVE ELEMENTS: In traditional Chinese belief, the world is composed of five elements: water, fire, wood, metal, and earth. In addition to the elements themselves, the way in which they interact with each other is very important, and this plays a role in traditional Chinese medicine and astrology. In the traditional Chinese calendar, each year is assigned an animal and an element. There are 12 animals and 5 elements, and so, all the possible combinations are exhausted after 60 years, when a new cycle of years begins. For this reason, the 60th birthday in Chinese tradition is very significant. (AG)
FIVE RELATIONSHIPS: The relationships in Confucius' teaching which define inter-personal relations in society. The five relationships are: relationship between a father and son, ruler and minister, husband and wife, elder brother and younger brother, friend and friend.

FODDER: Anything given on farms or sold for non-human animal consumption. Compare FOOD. (DM)
FOLIC ACID is a vitamin of the B complex group essential for cell growth and reproduction. The need for folic acid increases in pregnancy, infancy and periods of stress where a daily intake of 400 mg before conception and during early pregnancy lowers the risk of fetal neural tube defect (see spina bifida). Rich dietary sources are deep green leafy vegetables such as spinach, liver, beans, nuts and whole-grain cereals and bread (see SPINA BIFIDA). (IP)
FOLLICLE: The structure on the ovary surface that nurtures a ripening oocyte. At ovulation the follicle produces estrogen until the oocyte is released, after which it becomes a yellowish protrusion on the ovary called the corpus luteum. (DM)
FOOD: Anything consumed or sold for human consumption. Compare FODDER. Food can also be any substance consumed by living organism. (DM)
FOOD ADDITIVE: A minor usually synthetic ingredient added to food to achieve a specific effect. In law, some of these compounds are legally excluded from being called this term for the purposes of food safety regulation. (DM)
FOOD AID: Food Aid is internationally distributed humanitarian famine relief and emergency food assistance, for example from non-government organizations (NGOs) or the UNs Food and Agriculture Organization (FAO) and World Food Programme (WFP). Food aid should be deployed directly to where it can save lives, independent of economiuld be taken that food is not redirected to the wealthy or the armed forces. Care should be taken not to undercut local markets or encourage a handout economy. Ntant, and some African countries have rejected genetically modified foods. Food aid should include local capacity building in agriculture and technology, developlf-reliance and long term food security. (See FOOD CRISIS, FAMINE, NUTRITION, CAPACITY BUILDING) (MP)
FOOD CHAIN: = energy transfer from plants to top carnivore through a few intermediary organisms- the act of repeated eating and being eaten. (JA)

The FDA's basic tasks are research, inspection and licensing of drugs and food-stuffs for manufacturing and distribution. (IP)
: The conceptual web of food connections between organisms in an ecological community. Primary producers create organic matter and are eaten by grazers (herbivores), which are in turn eaten by carnivores. Formerly, this was called a food chain, but recognition that such links are often nonlinear lead ecologists to change this to food web. (See TROPHIC INTERACTIONS, AUTOTROPH, HETEROTROPH) (RW)
FORCE FEEDING : Coercive feeding, usually artificial feeding. (DM)
FORENSIC DNA ANALYSIS : Powerful tool for identification of individuals in forensic cases. The DNA analyses are performed on semen, blood stains, hair roots or any other biological evidence. Different DNA polymorphic regions can be analysed: VNTRs, STRs, mitochondrial D-loop region (mtDNA replication region).

E.g. use of DNA finger printing to determine the human identity with a victim, the time of murder inferring the patterns of breeding in insects. (JA)
FOREST: Large area of land dominated by trees. Massive deforestation has taken place in many countries to the extent that in only South America and Africa were there significant amounts of native forest left at the start of the twenty first century, and these were rapidly being removed. The full ecological consequences of widespread deforestation are still unknown but certainly include soil erosion and probably include significant, undesirable and difficult to reverse climate change. (MR)
FORMALISM a deontological (from Gk deon meaning duty) ethical system where the theory holds that an action is right if it accords with a moral rule, and wrong if it violates such a rule.
FOSSIL FUELS : Fuels derived from the fossilized remains of plants and animals. For example, coal is the remains of primeval forests; petroleum and natural gas are the remains of prehistoric animals and plant; peat is partly decayed plant matter in an early stage of coal formation. Fossil fuels are precious non-renewable resources. (See SUSTAINABLE DEVELOPMENT, GREENHOUSE EFFECT). (IP)
FOSSIL RECORD : (Latin fossus 'dug up'). Objects such as the remains or traces - like foot prints, burrows, trails referred to as 'trace fossils' - of fauna and flora which have been embedded, typically, in shale or sandstone which prevented their decay. Since fossils prove the previous existence of extinct organisms, the fossil record lends strong support for the theory of evolution, and is also useful to the geologist in revealing former environmental conditions in geological time (geochronology). The presence of certain fossils can be used as a guide to the relative age of the rock stratum or bed in which it is found; that is, to correlate the sequence of stratified formation in different parts of the world. (See FOSSIL FUELS, EVOLUTION). (IP)
FOUNDER EFFECT: Evolutionary adaptation and speciation which results in rapid change (punctuated equilibrium) due to sudden mass mortality or genetic partitioning, for example geographical separation, natural disasters or other evolutionary bottlenecks.

The well-known four freedoms are 'freedom of speech ', 'freedom of worship ', 'freedom from economic want' and 'freedom from aggression '. Nowadays a fifth freedom can well be added - 'freedom from excess fertility' . (See FREEDOM). (IP+MP)
FOUR NOBLE TRUTHS: Philosophical teachings of the enlightened Buddha: 1. life has omnipresent suffering; 2. suffering involves a chain of causes including desire and selfishness; 3. suffering can be removed by removal its causes such as desire; and 4. there is a path towards this end (the Eightfold Path).

FREE MARKET: An economic system (or lack of system) in which uncontrolled competition rules, only the fit (in terms of success in marketing goods, services, or one's own body, survive, and the main motive is profit. The profit may be money, or material goods or food (as may be observed when chickens fight over a piece of food). Or it may be pride, honours, fame or the like. Many people have been convinced that the fall of the Soviet Union was proof of the evils of socialism and the gospel truth of free market ideology, although there may have been other causes such as subversive activity on the part of Western countries. (FL)
FREE MARKET MEDICINE: An ideology which encourages the profit motive in medicine. An extreme version would allow for people to be treated only if they have the ability to pay, although some doctors in such an environment might be willing to treat some people for free if it serves some research purpose. Medical systems which began with an ideology of universal, egalitarian medical care, such as the National Health Service in the United Kingdom and the Sick Funds in Israel, now are mixed with varying degrees of free market medicine in the form of private clinics, fee charging for special treatment on the part of physicians even during their work hours in the national medical system, and high prices (or special insurance policies) for certain treatments and medications, such as expensive drugs, certain kinds of preventive medicine, immunizations for foreign travel, etc: with competition among providers for offering the most attractive insurance packages. It can be debated whether a physician in a free market system can adhere to all of the recognized principles of bioethics, especially the principle of beneficence. For it is questionable whether a physician can act entirely for the benefit of the patient if the patient's ability to pay determines the quality and quantity of treatment. (FL)
FREEDOM: The absence of external constraints on the individual's right and ability to act and make decisions. (DM)
FRESHWATER : Water that is not salty. As an adjective, of, relating to, or living in water that is not salty.

(RW)
FREUD, SIGMUND : (1856-1930). Austrian physician and pioneer of psychoanalysis. Freud's major contribution can be broadly summarized as the exploration of the unconscious mind and his coining of the term 'id' to define the true unconscious representing the individual's self-preserving tendencies and instincts. Freud claimed that interpretation of dreams is an important factor in psychoanalysis. By studying the dreams of his patients, Freud crystallized his theory that nearly all cases of neurosis were due to repression of sexual desires. His theory was published in the influential text 'Three Treatises on the Sexual Theory ' in 1905. Freud's influence in the 19-20 th centuries cannot be underestimated as almost every branch of thought, particularly in education, was affected by the theories of psychoanalysis. (See DREAM). (IP)

FUNGAL TOXINS : The fungi Fusarium can produce a toxin known as deoxynivalenol or DON. Fungal infection of food-crops (such as wheat) can harbor DON. Unfavorable weather conditions can strongly influence the concentration of DON in wheat. In animals , exposure to high concentrtion of DON has adverse effect on the immune system, fertility and in embryo development. ( JA).
FUNGI: One of the five taxonomic kingdoms (along with Animalia, Plantae, Protista and Monera), the Fungi are a diverse group of heterotrophic organisms with a rigid cell wall. Lacking chloroplasts, the fungus obtains its nutrients from mineral absorption through its hyphae and mycelium. Fungi perform an important ecological function as decomposers. Fungi include mushrooms, toadstools, bracket fungi, lichens, water molds and unicellular organisms and range from edible to poisonous. (See LICHEN, DECOMPOSE, PSILOCYBIN, PLANTAE) (MP)

Limits to Growth
(1972), K. Eric Drexler
Engines of Creation
(1986), Marvin Minsky
, Michio Kaku
(1998), Lee Silver
(1998) and Frank Tipler
Physics of Immortality.
Futurologists have traditionally been somewhat optimistic in their time-frames (e.g. George Orwell
), but the accelerating pace of change will bring current technological predictions more rapidly. New and dangerous spaces of possibility have recently been opened up by new advances in genetic engineering, genetic medicine, cloning, cybernetic nerve-computer interfaces, cyborgs, organization of cyberspace, artificial neural networks, networked sensor arrays, smart dust, miniaturization of robotics, autonomous weapons, molecular electronics, nanotechnology, and evolutionary approaches to artificial life. Insight into single-technology possibilities has grown rapidly, however professional specialization has not allowed for proper consideration of their potentially dramatic impacts in combination. Success rates can be patchy if projected too far into the future along assumed curves which may be subject to sudden or unexpected interferences. This significance may be crucial to human survival and wellbeing, and despite skepticism, futurology is an essential and underrated component of dealing with the progress of ethically fraught technologies.

GAME THEORY: Game theory is the stu games of chance, strategy games and war gaming. Standard game theories include chicken, prisoners dilemma and minimax, and military game theories include STAGE (Simulation of Total Atomic Global Exchange) or the US Armys TACSPIEL (divisional tactics) and AGILE (counter-insurgency). The game is defined by the rules governing moves, examples including conflict, coordination, cooperation, coalition and positive-sum games. Game theory is a scary term in some ways, in a world where actors treat internet, economic and military affairs as a big game whilst safely shielded from the real-life consequences of their actions.

Generality or a generalization implies a common theme or average measure of similarity across a range of subjects, and indicates the breadth of relevance of certain processes, philosophical ideas or research. General knowledge refers to common wide-ranging knowledge, but with facts readily accessible in academic literature and the internet, today a generalized education IDISCIPLINARY) (MP)
1. where the name of a particular drug also describes its chemistry; such as penicillin or tetracycline 2. pertaining to a substance, product or drug that is no longer protected by trademark and where this product, identical or closely related to the original, is placed on the market by a manufacturer other than the holder of the original patent. No new clinical trials are required by the new supplier as it is assumed that the generic drug is safe and effective; thus, typically, these drugs cost a fraction of the original price. Generic drugs are also called "me-too" drugs (Latin
GENETIC CODE: The sequence of base pairs in DNA providing information to form proteins. (DM)
GENE CONSTRUCT : A gene sequence prepared under laboratory conditions for transgenic transfer where the desired characteristics will be expressed. (JA)
GENE CHIP: An array of probes of nucleic acid on a chip for rapid assays of genetic variation, and mutated DNA sequences in an organism. Gene chips may allow for the diagnosis of all the genes of a genome in one test, and analysis is done by computer technology. (DM)
GENE DIAGNOSTIC TESTING : The presence of a faulty gene can be detected by techniques using the results on the gene structure e.g. association of BRCA1 with breast cancer. (JA).
The process by which a gene's blueprint is converted into the structures present and operating in the cell. Expressed genes include those that are transcribed into mRNA and then translated into protein and those that are transcribed into RNA but not translated into protein (e.g., transfer and ribosomal RNAs). Appearance of a phenotypic characteristic specified by a gene like the shape of a fruit/color of a seed (DM, JA)
GENE FAMILIES: Groups of closely related genes that make similar products.
GENE GUN - a method for introducing foreign particles or genes into cells. The accelerating particles have a diameter sufficiently small to penetrate the surface membranes and be retained in a preselected cell without killing the cell. The idea is for the gene to be functionally incorporated into the interior of the cell without disrupting normal gene sequences (see GENE THERAPY). (IP)
GENE KNOCKOUT : An organism that has been genetically modified so that one gene is knocked out, or dysfunctional, for use in biomedical research of gene function. (DM)
GENE PATENTING: There has been controversy over the issuance of patents to nucleic acid sequences, and article 4 of the Universal Declaration on the Human genome and Human Rights, approved by all members of UNESCO in 1997 states "The genome in its natural state shall not be patented". In considering DNA as an assert or a property the following three arguments have been raised in a Nuffield Bioethics Council Report. 1. Patents that assert rights over DNA sequences, in particular human DNA sequences, should not be allowed by virtue of the special status es should not be allowd because they do not meet the legal criteria for patenting. 3. patents that assert rights over DNA sequences shounces for healthcare and research related to healthcare. (JA, DM)
The sum total of all the different GENES (q.v.) and forms of genes (ALLELES (q.v.)) found in a POPULATION (q.v.) or other collection of organisms within a SPECIES (q.v.). So the gene pool contains all the genetic variation found among the organisms in question.

GENE TRANSFER refers to the spread of genetic material through natural genetic mechanisms. Little is known about the frequency of genetic exchange in Nature. Recent concerns are about outcrossing to wild varieties of genetically engineered plants and risk of transfer of foreign DNA across to insects, birds and mammals which normally consume some parts of the genetically modified organism and its long-term impact on those species (see GMOs) (IP)
GENERA : Plural term for genus. (See GENUS).
GENERAL ADAPTATION SYNDROME (GAS): was first described by Canadian physician Hans Selye in 1956 and describes the link between stress (whether physical or psychological) and nervous-hormonal activation resulting in the release of adrenaline (also called the fight-or-flight reaction), cortisol and other hormones involved in the emergency feedback loop to changing environmental influences. Since the hypothalamic-pituitary-adrenal axis is involved in the homeostatic adaptation to environmental and metabolic change, stress is necessary for continued adaptation, and in non-threatening situations is also the spice of life. Stress is harmful only when it's prolonged and ineffective where it can lead to degenerative conditions such as cardiovascular disease. Biologically, the essential thing is that the body must be prepared for changing circumstances by the initiation of an appropriate GAS response (see DISEASES OF ADAPTATION, STRESS, POST TRAUMATIC STRESS DISORDER; EUSTRESS; DISTRESS). (IP)
GENERATION : 1. Production, reproduction; the process of bringing something into being (e.g. the conception of offspring). 2. People in a social demographic having approximately the same age, perhaps also correlating with a certain outlook or attitude (e.g. the grandparent's generation). 3. A successive period in the reproductive evolution of a family lineage (e.g. about 35 years for humans). A generation is best measured not as the age of first breeding, but as the average age of the active parents in a population. (See GENERATION GAP, GENESIS) (MP)
GENERATION GAP : 1. The average length of time between successive generations of a population. 2. Perceived differences in the attitudes, opinions, behaviors and concerns of successive generations. The generation gap is created by shifts in philosophical frame of reference between age groups which have grown up in divergent avenues of social, cultural and technological evolution. This age barrier may be broken down using communication, curiosity and tolerance, and the avoidance of age-related habitual patterns and ingrained belief systems. (See GENERATION) (MP)
GENESIS : (Greek: gignesthai 'to be born') 1. Origin, first beginning. 2. The first book in the Old Testament of the Holy Bible of the Judeo-Christian faiths. The Book of Genesis begins with divine creation (Genesis 1.1: "In the beginning God created the heavens and the earth"), including the first humans Adam and Eve, created in God's image but banished from the Garden of Eden for eating from the tree of knowledge of good and evil. (See OLD TESTAMENT, TORAH, ORIGINAL SIN) (MP + JA)

(JA)
GENETIC COUNSELING : A process of consultation by which information is imparted to individuals or families affected by or at risk of a genetic disorder. It includes information on the nature of the disorder; the size and extent of genetic risks, the options, including genetic testing, that may help clarify the risks; the available preventive and therapeutic measures and the provision of psychological, social and practical support. In the context of genetic testing it may include responding to the concerns of individuals referred and their families, discussing the consequences of a test and enabling them to choose the optimal decision for themselves but not determining a particular course of action. (JA)
GENETIC DETERMINISM: Doctrine or theory that the genetic make-up of an individual absolutely characterises (i.e. determines) its appearance (i.e. PHENOTYPE (q.v.)). Strictly, the theory is entirely invalid in that a sufficient change in the environment (e.g. the absence of any water) is sufficient to prevent the phenotype being observed (in the case of the absence of water, because the organism will have died). However, the theory is of use in that certain characteristics, e.g. natural iris colour in humans, have a much stronger genetic component to them than do certain other characteristics, e.g. language spoken. At the same time, certain phenotypes which might be thought to be 'genetically determined' , e.g. the 'genetic disease' of PHENYLKETONURIA (q.v.), can be almost entirely avoided by appropriate changes in the environment, i.e. childhood diet in the case of phenylketonuria. (MR)
GENETIC DIAGNOSIS : See PRENATAL DIAGNOSIS, PREIMPLANTATION GENETIC DIAGNOSIS.
GENETIC DISEASE : Afflictions which are due to defects in the genetic endowment of a person. They may be the direct consequences of defects in single genes; or in whole chromosomes, part of which may be lost, duplicated or misplaced; or due to the interaction of multiple genes and external factors in fetal development. Later in life such interactions appear to be the basis of many of the common serious disorders, such as heart disease, diabetes and cancer. (see GENETIC DISORDERS, DISORDER GENETIC) (JA)
GENETIC DISORDER : A malfunction or a disability caused due to a genetic factor, which results in the manifestation of human diseases. E.g. a). phenylketoneuria b). Congenital hypothyroidism c).

GENETIC STATUS : It indicates the genetic condition of a person whether there are any genetic abnormality in a person. Three types of genetic status may be recognized. (i) a monogenetic condition in which a gene if present or absent may create a genetic condition which may be expressed or presymptomatic in nature. (ii) When a trait is controlled by one or more genes different types of environmental stimuli may induce difference gene response. E.g a mutation which lacks enough power to induce a phenotypic expression. (iii) a person may carry one defective copy of a gene but the healthy copy of a gene may dominate and the person may not suffer any ill effect. (JA)
A genetic risk for developing a disease. The disease may be simple or complex, and the chance of actually getting the condition or disease ranges from 1-100% between genes and individuals. (DM)
GENETIC TEST : Genetic testing is a part of diagnosis in pediatric practice. Tests that are carried out to detect the presence or absence of, or change in, a particular gene or chromosome, or a change in a gene product, in relation to a genetic disorder.

GENETICALLY MODIFIED ORGANISMS: See GMOs.
GENETICALLY MODIFIED VIRUS: Newly-developed strains of virus created by genetic engineering for specialized purposes such as biological control. For example, Australian research has genetically modified strains of virus to interfere with the ova of introduced mice and rabbits to render them sterile. New Zealand researchers meanwhile have designed a similar virus targeting possums, which are native to Australia. Ethical and ecological concerns include the potential for trans-national spread, potential impacts on related endemic mammals, and the grave avenue of ethno-terrorism and genetically-specific bioweapons.

The 1949 Geneva Conventions I-IV provide legal codes on the humane care and treatment of: Convention I - sick and wounded combatants, irrespective of race, religion or politics; Convention II - shipwrecked or wounded at sea; Convention III - prisoners of war, not to be used as hostages, labor, experimental subjects or torture; and Convention IV - protections and rights for civilians during war. The Geneva Conventions were followed up by Geneva Convention Protocols I and II in 1977. These international laws will have their teeth strengthened by international war law institutions such as the International Criminal Court. (See GENEVA PROTOCOLS, HAGUE CONVENTIONS, INTERNATIONAL HUMAN RIGHTS LAW, INTERNATIONAL CRIMINAL COURT) (MP)
GENEVA PROTOCOLS: The 1977 Geneva Convention Protocols I and II were an important addition to the Geneva Conventions of 1949. Protocol I refers to limits to the rights of parties to choose the means of warfare, prohibition of weapons causing superfluous suffering, and prohibition of means of warfare which cause widespread or long-term damage to the natural environment. Protocol II includes humane treatment of victims of non-international armed conflicts. (See GENEVA CONVENTIONS, HAGUE CONVENTIONS) (MP)

GENOCENTRISM the belief that the gene is at the center of all things. (IP)
GENOCIDE : Genocide is any political or military act committed with the intent of partially or wholly destroying a particular ethnic, cultural, religious or national population. It includes killing members of the group, causing serious mental/bodily harm, inflicting destructive conditions for life, imposing birth-prevention measures or forcibly transferring children on the basis of their race. It was the first of the war crimes to attract international legal condemnation with the 1948 Convention on the Prevention and Punishment of the Crime of Genocide. Conventional warfare and the use of force between nations are not necessarily genocide when directed at a political state rather than a specific racial or cultural group. (See EXTERMINATION, WAR CRIMES, CRIMES AGAINST HUMANITY, ETHNIC CLEANSING, GENEVA CONVENTIONS, INTERNATIONAL CRIMINAL COURT) (MP)
GENOME: All the genetic material in the chromosomes of a particular organism; its size is generally given as its total number of base pairs. Weighs about 200th billionth of a gram in humans. (JA)

GENOMIC LIBRARY: A collection of clones made from a set of overlapping DNA fragments representing the entire genome of an organism. Compare library . (DM)
GENOMICS: Characterizes the technologies supporting the science of genetics; that is, the DNA informational content of a cell. Since the late 1990s, the field has changed the way we view the biological world since all living organisms, whether bacteria or human, can now have their genomes completely sequenced and archived for ready access. Was a term originally coined to describe the discipline of science concerned with the mapping, sequencing and analysis of genomes - the complete set of genes from an organism and described the "parts manual" for an organism. The commercialization of genome technology, however, is usually focused on the discovery of medically relevant genes as potential therapeutic drug targets or identification of specific gene sequences that are correlated with genetic disorders. Modern advances in genetics have changed the way we view the biological world since all living organisms, ranging from bacteria to humans, can now have their genome sequenced, creating crucial issues of access and ownership of genomes (see BIOINFORMATICS; PROTEOME; PROTEOMICS). (IP)
GENOTYPE: The genetic constitution or makeup of an individual. (DM)
GENUINE PROGRESS INDICATOR: A monetary measure of national wellbeing and the progress of sustainability. Directly comparable to and based on the Gross Domestic Product (GDP), the Genuine Progress Indicator (GPI) goes further by adjusting for economic estimates of 24 additional factors. Among others, these include income distribution, crime, family breakdown, volunteer work, leisure time, resource depletion, pollution, environmental damage, public infrastructure, defensive expenditures and dependence on foreign assets. The GPI has revealed a gradual decline in national wellbeing since the mid 1970s for countries such as the USA, UK, Germany and the Netherlands. This indicates that even despite growth in GDP figures, the total environmental and social costs have outweighed the benefits of economic activity. (See PROGRESS, GROSS DOMESTIC PRODUCT, HUMAN DEVELOPMENT INDEX, INDEX OF SOCIAL HEALTH, SUSTAINABLE DEVELOPMENT). (MP)
GENUS: Level in the classification of organisms above SPECIES (q.v.) and below family. For example, the family Delphinidae (the DOLPHINS (q.v.)) contains 32 species in 17 genera. However, whereas species can be defined with come degree of objectivity, genera, families and the other levels in the classification of organisms are far more subjective. Their meaning is almost entirely the result of previous historical usage of the terms rather than of any feature of the natural world. (MR)
GEODESY : A branch of geophysics, survey methodology involving the mapping of biosphere, map making and correlating with geological, gravitational and magnetic measurements. (JA)
GEOGRAPHIC INFORMATION SYSTEMS (GIS): Computer technology for the storage, analysis, manipulation, synthesis and display of spatially referenced information. Overlay mapping allows the integration of multiple geographical or social data sets to find patterns, correlations and new information for strategic management.

GERM CELLS (GC) : Cells connected with reproduction, primordial cells found in testis and ovary. Egg and sperm cells and the cells that give rise to them. (see GENE THERAPY). (germ = reproductive) a reproductive cell precursor to the formation of a sperm or ovum (DM, JA)
GERM-LINE GENE THERAPY : A gene therapy technology targeting the germ cells that eventually produce gametes; that is, the oogonia in the ovaries and the spermatogonia in the testes. The protocol is of injecting correcting, modifying or additional DNA into the pronucleus of a fertilized egg. The technology requires that fertilization would occur in vitro using the usual IVF procedures of super-ovulation and fertilization of a number of egg cells prior to micromanipulation and embryo transfer. Deliberately targeting the human germ-line is problematical from biological and ethical view points, especially in view of unknown consequences passed down generations. To assume the right to manipulate our descendants in this way seems to be an extreme form of arrogance. (See SOMATIC-CELL GENE THERAPY; IN UTERO GENE THERAPY; GENE THERAPY). (IP)
The total genetic variability, represented by germ cells or seeds, available to a particular population of organisms. (DM)
GESAMP : Group of Experts on the Scientific Aspects of Marine Pollution. UN, UNEP, UNESCO. (JA)
GHOST SPECIES: Once a population decreases to a certain threshold, the species may be virtually doomed. Lacking sufficient genetic diversity, habitat size or ecological support, the species may live for some time as a non-viable population or require human intervention for the prevention of extinction. Such "ghost species" may lead to an underestimation of biodiversity loss as measured by extinction rate. (See BIODIVERSITY, ENDANGERED SPECIES, EXTINCTION) (MP)
GHB : GHB is short for gamma hydroxybutyrate, a recreational drug also known in the gay and club scenes since the 1990s as Liquid Ecstasy. GHB acts on the dopamine system and has been used medicinally in the past as an anesthetic and antidepressant. When swallowed it has euphoric and aphrodisiac qualities, but taken in excess it may progressively induce drowsiness, nausea, respiratory depression, coma and death. The likelihood of overdose is increased by co-consumption of alcohol and lack of quality control. (See ECSTASY). (IP+MP)

GINSENG: (Chinese : jen-shen "man image") The man-shaped root from plants of the genus Panax (from Greek: panacea ). Ginseng grows in China, Japan, Korea and America and is a popular remedy in East Asian and North American traditional medicines. Its tonic, stimulant and aphrodisiac properties are said to be good for digestive, nervous, pulmonary and vitality disorders. Some of the active constituents are steroid compounds, so care should be taken with regular use especially during pregnancy. More modern medical research is required to gauge the safety and efficacy of traditional herbal remedies such as ginseng. (See HERBALISM, BUSH MEDICINE). (MP)

GLOBAL WARMING: (See GREENHOUSE EFFECT, CLIMATE)
: Globalization commonly refers to a tendency to transcend the boundaries of the nation state. This tendency can be observed in almost every aspect of modern life: ideologies, economics, technical advances, transnational regulations, environmental problems. Whereas in the course of the 20
century, nation states have been the main agents in the international community, they are increasingly being replaced by non-governmental and/or transnational actors. Environmentalist movements operate worldwide, international organizations address the problems of global warming or the problem of poverty, and transnational companies are important players on the world market. High technology advances (media, the internet) have enabled individuals to communicate with others in any part of the world, hereby enabled them to participate globalizing their lives.
Nevertheless, globalization cannot only be viewed as a desirable process. Many critics have been addressing the problems that globalization poses: while it broadens the options for westerners and highly educated elites all around the world, it increases discrimination of the poor even further. In this context, globalization can be defined as the spacial and temporal approximation of world regions that have access to high tech means for communication and information. (BP)

GODS: Usually "God" refers to the One God, while "gods" refers to deities of polytheistic religions. In polytheistic religions, sometimes statues or other idols are referred to as "gods", but deeper thinkers regard these as material representations of concepts or of spiritual beings. The similarity between the gods of "polytheistic" religions and the angels (q.v.) of "monotheistic" ones may make the distinction between polytheism and monotheism outdated.(FL)
GOLDEN RULE: An almost universal principle of ethics, the Golden Rule is summarized by the phrase Do unto others as you would have them do unto you . Variations on this theme recur across most religions and ethical philosophies, including Zoroastrianism, Confucianism, Jainism, Buddhism, Christianity, Islam, in the Mahabharata , the Book of Leviticus , Kant, Mills Utilitarianism , and Rawls Theory of Justice . Deep Ecology also recognizes the golden rule for the Earths other species and ecosystems. (See RECIPROCITY) (MP& MV)
: about 200 million years ago all major continents were locked together in a supercontinent named Pangea (meaning "all Earth"). Pangea began to break up about 190 million years ago. First, the northern group of continents (Laurasia) split apart from the southern group (Gondwana). Laurasia formed North America and Eurasia while Gondwana broke into three parts; Africa-South America, Australia-Antarctica and India. India drifted northwards and collided with Asia which collision initiated the uplift of the Himalayas. Subsequently, South America and Africa separated and Antarctica separated from Australia. From the outset, continental drift has been closely interwoven with that of evolution. Australia, which has been separated the longest from other continents (about 65 million years) has the most distinct biota, including its indigenous people. Interestingly, the first evidence of life on Earth comes from the north-west of Western Australia, where microbe-size fossils, some of which may have produced oxygen, have been dated at 3.465 billion years before present. South America has the next most distinct biota, having been isolated from other continents for nearly 60 million years. North America and Eurasia, which were joined together for much of Earths history, have very similar biotas. (IP)
GOOD SAMARITAN: The term originates in the New Testament story in the book of Luke (chapter 10). In that story, a Jewish man was attacked by thieves and left for dead. As he lay there by the side of the road hoping for help, two people walked by without extending any assistance. Then a Samaritan (inhabitant of the Samaria region, and traditional enemy of the Jews) took the wounded man to an inn, tended to his wounds, fed him, and paid his expenses. The exemplary behavior of this Samaritan was remembered in the expression "good Samaritan", which was later extended to refer to anyone who saw a person in need and extended assistance. (AG)
GOSSES: A Hebrew word referring to a patient who is in the process of dying. There is no clear and universally accepted definition of the word, although some physicians and nurses say that they can recognize someone who is about to die. In Jewish Law, "halacha" (q.v.) a gosses is regarded as totally alive. This means that it is forbidden to disturb a gosses in such a way as to hasten death. It is for this reason that some Rabbis forbid testing for brain death with advanced methods of imaging, because it may disturb a gosses. And killing a gosses is murder. On the other hand , a distinguished Israeli Rabbi, Rabbi Itzhak Silberstein, in "Assia", the Hebrew journal of Halacha and medicine, argued that it is a question which requires further deep study, whether the Law of the Pursuer (Din ha-Rodef, which requires one to take violent action against anyone who is acting so as to threaten the life of an innocent person) applies at all when the threatened person is a gosses.

GRAY GOO CATASTROPHE: This term is used in nanotechnology discourse to refer to the possibility of an apocalyptic end to life on Earth as a result of accidental release of the wrong replicating assemblers. Nanotechnology "bacteria" could be designed to utilize elements such as carbon from their surroundings to replicate more of themselves in an uncontrollable chain reaction. This evolutionarily superior "gray goo" may spread rapidly across the globe to obliterate all species including its creator. (See NANOTECHNOLOGY, NANOTECHNOLOGY WEAPONS) (MP)
GREAT APE PROJECT : A book title and organization. The idea is to include the nonhuman great apes (chimpanzees, gorillas and orangutans) within the community of equals by granting them the basic moral and legal protection that only human beings currently enjoy. The book is an edited work from a group of scientists and scholars against the unthinking denial of fundamental rights, or moral protections, to beings who are not members of our own species, but who quite evidently possess many of the characteristics that we consider morally important. The organization is an international group founded to work for the removal of the nonhuman great apes from the category of property, and for their immediate inclusion within the category of persons . Their long-term goal is a United Nations Declaration of the Rights of Great Apes. (Web site: http://www.greatapeproject.org/) (DM)
GREAT BARRIER REEF MARINE PARK: Australia is home to the largest coral reef in the world, the Great Barrier Reef extending from tropical latitudes to temperate ones, a super-organism visible from space. It is managed as a multiple-use zoned Marine Park. Forty different bioregions are recognized; within these Green Zones are protected, Yellow is for recreational fishing and Blue for commercial fishing excluding trawling. Many of the worlds coral ref Marine Science and Great Barrier Reef Marine Park Authority. (See CORAL REEF, MARINE PARK) (MP)
GREED: (Old English graedig "covetous"). Excessive desire to acquire or consume more than is reasonable or fair, for example in relation to wealth, power or resource consumption. (see SUFFICIENCY). (MP)
grow) The adjective green implies association with ecology, conservation of nature and relevance to environmental issues; for example the green revolution involved new high-yield agricultural techniques, a green belt is uncultivated nature or parks surrounding a community, greenery is growing plant foliage, greens are leafy vegetables, and a green thumb implies gardening ability. The green activist movement has been building since the early 70s along with green politics and organizations such as Greenpeace. Conservationists have become greenies with shallow/light green or deep/dark green ideologies. Green is also increasingly used as an adjective - green products, and as a verb - greening a corporate image. (See GREEN MOVEMENT, GREENIES, DEEP ECOLOGY, ECOLOGISM, ENVIRONMENTALISM) (MP)
GREEN BAN: Green Bans are strikes or union bans imposed in recognition of particular ethical or environmental concerns identified by the workers or community. (See GREEN MOVEMENT, INDUSTRIAL ACTION) (MP)
GREEN CONSUMERISM: Concern for the environmental and human health has created economic demand for green products, green labeling, recyclable materials, organic foods, soft energy/technology, green standards of practice, corporate responsibility/liability, ethical investments, etc. Multinational corporations have responded, not only in forms like the Body Shop and health-food stores, but more broadly across the spectrum - corporate and executive images are being cleaned and greened ranging from Microsoft to British Petroleum. The power of consumer demand is one of the motivating factors towards a green economy; others include green politics, green taxes etc. (See GREEN, ENVIRONMENTAL ECONOMICS, ECOLOGICAL ECONOMICS) (MP)
GREEN FLASH is an intense, brief flash visible under certain conditions following the moment the sun goes beyond the horizon. The phenomenon is due to refraction of light rays from the setting sun as they pass through the lower layers of the atmosphere (see CORONAS, RAINBOWS, MIRAGES & HALOES). (IP)
GREEN MOVEMENT: A strong international activist movement and political viewpoint which has the following central assumptions: intrinsic value and preservation of nature, eco-centrism, ethical value systems, sustainable development, grassroots democracy, social and economic justice, disarmament and non-violence. It involves movement towards the alternative environmental paradigm of a decentralized, non-consumeristic, non-nuclear, participatory, harmonious society. The green movement shares the aims of the peace movement and some of those of the anti-globalization movement, recognizing that ecological values require factoring in to human activities, and that poverty itself comprises a threat to environmental protection. Some of the earliest environmental political groups were formed in West Germany by people such as Petra Kelly, the German Greens, Grüne Aktion Zukunft and electoral candidate green lists. Politicalerately strexample, the Green Bans from 1971, partly inspired by the womens group Battlers for Kellys Bush, werement oment iing, salinization), despite efforts such as the National Strategy for the Implementation of Sustainable Development in combination with the National Parks and Wildlife Service and organizations such as Australian Conservation Foundation and the Wilderness Society. Globally the movement includes United Nations Environment Programme (UNEP), International Union for the Conservation of Nature and Natural Resources (IUCN), environmental watchdogs like WorldWatch Institute, green charities like World Wildlife Fund, and activist networks like Friends of the Earth and Greenpeace. Prominent international contributors to the green movement have included in no particular order Rachel Carson, David Suzuki, Gro Harlem Brundtland, David Attenborough, Chico Mendes, Jane Goodall, Dian Fossey, Wangari Maathai, Jacques Cousteau, Paul Ehrlich, Theodore Roszak, Richard Leakey, Edward Goldsmith, Lester Brown, Norman Myers, Howard Rheingold, James Lovelock, Amory and Hunter Lovins and E.O. Wilson. (See GREEN, GREENIES, GREEN CONSUMERISM, ENVIRONMENTALISM, ACTIVISM, PEACE MOVEMENT, ANTI-GLOBALIZATION MOVEMENT, SUSTAINABLE DEVELOPMENT) (MP)
: The very large increase in agricultural productivity in the late 20
Century facilitated by the introduction of high-yielding crop varieties, increased use of pesticides and fertilizers, and improved management techniques. The Consultative Group for International Agricultural Research (CGIAR; http://www.cgiar.org/) coordinates a network of international agricultural research institutes focused especially on the needs of developing countries; CGIAR has been involved in many of the innovations that made the green revolution possible.

GREENHOUSE EFFECT: Trapping of heat within the Earth's atmosphere. If the Earth had no atmosphere, its average surface temperature would be about -18 oC but the various GREENHOUSE GASES (q.v.) prevent much of the incoming radiation from the Sun from being re-radiated out into space. Some of these gases, particularly carbon dioxide, are increasing in concentration as a result of human activity - particularly the burning of fossil fuels. (See GLOBAL WARMING) (MR)
GREENHOUSE GASES: Carbon dioxide, water vapour, methane, nitrous oxides, chlorofluorocarbons (CFCs), nitrous oxides and the other gases that trap heat within the Earth's atmosphere. (See GREENHOUSE EFFECT) (MR)
GREENIES: Colloquial term for people active in or concerned with conservation, environmental issues or green politics. People with a green outlook range from everyday citizens through to deep ecologists and radical activists, and usage of the term greenie ranges from friendly to derogatory depending on perspective. Greenies may have much in common with related groups, especially with the peace movement (peaceniks), small-scale sufficiency lifestyles (hippies), and to a lesser degree with socialist ideology (reds). Greenies should try not to be inexperienced or gullible (greenhorns), avoid over-consumption (unlike the yuppie), and stand opposed to those who fight, hunt or discriminate (rednecks). (See HIPPIES, YUPPIES) (MP)
: (1939- ). Australian writer and feminist whose influential best seller
'The Female Eunuch'
(1970) became in the 1970s the public face of feminism. Greer rejects the stereotype of femininity that 'castrates' women by conditioning them to believe that passivity and dependence is the natural female state. Throughout her career she has urged women to fight against this artificial attitude and, if they are to fully express their genetic creativity, encouraged them to explore their sexuality. In her later works Greer investigated the importance of motherhood to women in
'Sex and Destiny: The Politics of Human Fertility
' and whether aging post the menopause is a special kind of female liberation in
'The Change: Women, Ageing, and the Menopause'
1991. (See BEAUVOIR, SIMONE DE, DWORKIN, ANDREA). (IP)
GROSS DOMESTIC PRODUCT (GDP): GDP is an aggregated annual measure of the total market value of goods and services produced within a nation. "Gross" implies that expenditures on replacement of capital goods are not deducted, and "domestic" implies that incomes from foreign investments are not included. The problem with GDP lies in how the statistic is used and interpreted. GDP is an index of economic turnover rather than national wealth, as it fails to measure the value of unpaid and voluntary work, or the economic potential of existing infrastructure and unexploited natural resources. Importantly, it does not differentiate between detrimental and sustainable generation of income, masking the impacts of some economic activities on social and natural systems. For example, GDP registers economic gain from such things as accidents requiring medical treatment, inbuilt obsolescence of goods, and environmentally destructive developments. The common use of GDP per capita as a measure of quality of life or human wellbeing is therefore flawed by its inability to pick up such social and environmental consequences. A nations GDP must be compared with other broader indicators such as the Human Development Index or Genuinethe people. (See GROSS NATIONAL PRODUCT, GENUINE PROGRESS INDICATORS, HUMAN DEVELOPMENT INDEX) (MP)
GROSS NATIONAL PRODUCT (GNP): GNP is an aggregated annual measure of the total market value of goods and services produced by a nation, including income from overseas investments but excluding income to overseas investors. GNP influences the distribution of power and policy in the international economic system, for example voting power in the International Monetary Fund. Although GNP is a useful economic statistic, it is not necessarily an accurate measure of sustainable progress or human well being. (See GROSS DOMESTIC PRODUCT, GENUINE PROGRESS INDICATORS) (MP)
GROUNDWATER: Sub-surface fresh water infiltrating the spaces between soil particles, contained in permeable rock or in voids between rock layers. Sustainable management of the saturated "water table" is required to prevent soil and groundwater salinity. In the upper "vadose" zone, some water is bonded to soils, whereas the "phreatic" zone is beneath the saturated level of the water table. Underground reservoirs and aquifers such as Australias Great Artesian Basin are not necessarily renewable and require protection from pollution and overuse. (See WATER CYCLE) (MP)

GROWTH: Enlargement (increase in size, development, knowledge, wealth). Growth is an existing characteristic of many global phenomena, such as human physiology, human populations, size of corporations, successful industries and certain value systems. With growth can come inequality and decreased wellbeing, for example profits to rich international food chains instead of local food merchants. In a world of limits, growth often comes at the expense of others or the environment. Such negatives are measured as growth in indicators such as Gross Domestic Product (GDP), but should not be considered progress or sustainable development. Growth implies a transition to maturity - the application of mature ethical principles to wisdom. Hopefully growth to collective maturity is the next stage of progress. Ironically perhaps, those attempting to spread free the ideas and applications of sustainability and bioethics can learn from growth practices such as efficiency and marketing. (See ADOLESCENCE, DEVELOPMENT, PROGRESS, GROSS DOMESTIC PRODUCT, EXTERNALITIES, OLD AGE) (MP)
GROWTH HORMONE (GH):
A hormone which contributes to the growth of a child. Its availability may also be related to the aging process. GH from cadavers was once used to replace GH deficiency in short-stature children. But a suspected link between cadaver-derived GH and Creutzfeld-Jacob disease encouraged the development of genetically engineered GH derived from genetically modified E-Coli. The use of GH for healthy, non-GM deficient, but short stature children raises bioethical questions of pediatric informed consent, of whether "short-stature" is a medical or a culture-relative term, and of whether medical solutions ought to be applied to problems for which alternative solutions, such as sport, martial arts, change of attitude and lifestyle, might be tried. These questions are all the more salient since there is no conclusive evidence that GM treatment for healthy, short-stature children affects final height rather than just growth rate. (FL)
GUERRILLA WARFARE: See INSTITUTION OF WAR, CHE GUEVARA.

GURU GRANTH SAHIB : The most sacred book of the Sikhs, compiled by Guru Arjan (1563-1606) (see Sikh). This book is so revered by the Sikhs it is given the honorary title of "Guru" (teacher). This title is usually only applied to human beings, and so, when used in connection with this text, it conveys the idea that one is standing in the presence of a teacher when standing before this book. A central theme of the Granth is the unity of God and God's transcendence. The book contains many hymns praising the greatness of God. (AG)
GUT: See GRAND UNIFYING THEORY OF NATURE. Also a term for the intestinal tract.
GYMNOSOPHY: "Gymnos" means nudity in Greek, and "Sophia" means wisdom. Gymnosophy is an ethic encouraging nudism (q.v.) as a way of divesting oneself of attachment to material possessions or to anything which covers what one really is or makes one appear other than what one really is, in order to achieve a more spiritual state, a greater closeness to nature, or more authentic relations with other people. There have been gymnosophical sects since ancient times, and there is a gymnosophical branch of Jainism in India today. In the 1960's and 1970's in the West, public nudity was a form of protest against war, capitalism and authoritarianism. This was a neo-gymnosophy, although the word was not used. (FL)
GYMNOSPERM: The cone-bearing trees, evolutionarily older than the angiosperms, for example conifers and boreal forest such as pine, spruce and fir trees. (See CONIFEROUS FOREST, SOFTWOODS, ANGIOSPERM) (MP)
Branch of medicine dealing with diseases of the female reproductive tract.(see obstetrics). A branch of medical science that deals with the physiological condition and function of the reproductive system of women.
It has been confused for not dealing with broader aspects of women's health.

HABITAT CORRIDORS: The impacts of habitat fragmentation can be somewhat alleviated by the provision of habitat corridors: wide connecting areas of appropriate habitat to link existing ecosystems and allow connectivity, biophysical regeneration, migration, genetic exchange, foraging routes, ecosystem services and biodiversity conservation. A corridor implies free movement, ranging from wildlife tunnels under large roads to large-scale links between National Parks. Habitat corridors also provide aesthetic values and hazard protection to intervening suburban landscapes. (See WILDLIFE CORRIDORS, HABITAT FRAGMENTATION, RESTORATION ECOLOGY) (MP)
HABITAT DEGRADATION: Habitat degradation is the gradual erosion of environmental integrity, quality, biodiversity and aesthetics, leading ecosystems into a state of fragmentation and several steps closer to destruction. Usually a result of human activity, habitat degradation includes industrial pollution, climate change, forestry and mining operations, dams, desertification, salinization, loss of land fertility, erosion, edge effects, ecological effects of pesticides, water diversion, river turbidity, eutrophication, trawling, coral bleaching, introduction of diseases, exotic predators, invasive weeds or vulnerable genetic stock etc. New generations may not bear witness to the true beauty and bounty of surroundings they inherit, and adjust to a lower standard of environmental quality and diversity. (See HABITAT DESTRUCTION, HABITAT FRAGMENTATION, ENVIRONMENTAL INTEGRITY) (MP)
HABITAT DESTRUCTION: Widespread forms of habitat destruction, which lead to fragmentation of what remains, include deforestation, land clearing, slash and burn cultivation, cattle ranching, large-scale agriculture, large-scale mining, the effects of large dams, industrial warfare, industrial and suburban encroachment, urban sprawl and the ecological footprint of cities etc. Of human activities, agriculture and grazing occupy the most land-surface area, with corresponding opportunity cost for natural ecosystems. Habitat destruction is obviously one of the priority issues in environmental ethics, requiring political and community activism and economic restructuring.

(from the Arabic root H.d.th., meaning "to report, to relate") Collections of traditions relating to Muhammad and his companions. These traditions carry considerable weight in terms of Islamic customs. Various Hadith collections exist, and each is listed according to the name of its compiler. The chain of transmission of traditions carries great weight in Hadith collections, and each Hadith tradition is quoted preceded by the chain of narrators who transmitted it from teacher to student. As a result, the most important Hadith collections are the ones with the clearest and most reliable chain of transmission. The most authoritative collection of Hadith is that of al-Bukhari. (AG)
HAGUE CONVENTIONS : The first (1899) and second (1907) Hague Peace Conferences were early conventions to limit the conduct of warfare and development of inhumane and expensive armaments. The Hague Conventions are legal codes for the conduct of war, including prohibitions on the use of poison gas, attacks upon surrendered soldiers, attacks upon undefended civilian targets, or weapons calculated to cause unnecessary suffering. The Hague continues its involvement in international human rights law, for example the 1923 agreement to restrict aerial bombing to military not civilian targets, and since 1993 the Hague War Crimes Tribunal. (See HAGUE TRIBUNAL, GENEVA CONVENTIONS, LIEBER CODE, INTERNATIONAL HUMAN RIGHTS LAW) (MP)
HAGUE TRIBUNAL: The Hague Tribunal for War Crimes in the Former Yugoslavia was established for the UN Security Council in 1993 to uphold international humanitarian law over alleged crimes against humanity perpetrated during the Balkan Wars, by defendants including Dusko Tadic, Radovan Karadzic, General Ratko Mladic and President Slobodan Milosevic.

HALACHA: A Hebrew word literally meaning "walking", and referring to the path which a religious Jew is expected to follow in life. Etymologically and semantically, the word is therefore similar to "DO" in Japanese and "TAO" in Chinese. Its basis is the Bible, especially the first five books, which are called the Tora. According to tradition, the Tora was given to Moshe at Mount Sinai in a written form, together with an oral interpretation, which was passed on by word of mouth, from generation to generation, until much of it was finally written down, in the "Mishna", during the time of Roman rule in the Land of Israel. But writing it down did not mean that there would not be further need for interpretation, and further discussions, commentaries and legends were written in the first centuries A.D. in the Talmud. This process of continuous discussion and interpretation has continued to this day. The entire corpus, includes thousands of books. Those opinions upon which there is wide consensus are collectively called the Halacha.
Halacha includes religious guidelines having to do with prayer, Sabbath observance, Jewish dietary laws, etc, as well as the future bringing of sacrifices to God-about which there is a debate whether they will include animals or be vegetarian. It also includes laws of ethical behavior between friends, neighbors and business associates. Halachic authorities, moreover, have always dealt with great bioethical questions arising in the social and scientific contexts of their times. Today there is a growing body of Halacha dealing with biomedical ethics, environmental ethics, animal rights, etc. A general introduction is in Rabbi Immanuel Jakobovits' book: Jewish Medical Ethics. There is also a journal of halacha and medicine, Assia (meaning "physician" in Aramaic) which appears in Hebrew and English. (FL)
HALAL: Arabic word meaning "permissible". In the context of diet, this term refers to foods which are permissible to observant Muslims. Some of the key factors involved in Halal foods include: Avoidance of the pig and its products, avoidance of meat from an animal which was not slaughtered at the neck with a pronouncement of the name of God over it, and avoidance of alcohol. The status of certain sea creatures is debated, and is considered Halal by some Muslims, but not by others. Most food products which are kosher (see KASHRUT) are considered Halal as well. (AG)
HALF-LIFE: See METABOLISM, RADIOACTIVITY.
HALLUCINATION a sensory perception occurring in the wakeful state which is not the result from external stimuli and may be auditory, gustatory, olfactory, tactile or visual. Hallucinations may be induced by drugs or may be a symptom of mental or physical disorders; such as noted in schizophrenia (Latin alucinari to wander in mind). (See HALLUCINOGENS) (IP)
HALLUCINOGENS : one way to classify drugs is by their major effect(s) but, typically, there are numerous areas of overlap. The drugs which cause hallucinations (a marked change in the user's sense of the world) are classified as hallucinogens. These include drugs of potential abuse such as mescaline, LSD, magic mushrooms and similar substances. The most well known hazard is the so-called 'bad trip', manifested by uncontrollable fear, panic and a feeling of impending insanity. (See HALLUCINATION, PSILOCYBIN, RECREATIONAL DRUGS). (IP).
HALOES are a colored or whitish ring or arc of light around and extending outwards from the sun or moon when seen through an ice crystal cloud or a sky filled with falling ice crystals. In general the processes of reflection, refraction, scattering and diffraction, individually or in combination, produce a wide variety of beautiful optical phenomena in the atmosphere (See AURA, CORONAS, RAINBOWS, MIRAGES, HALOES & GREEN FLASH). (IP)
HANDICAP a social disadvantage resulting from an impairment or disability which limits or prevents the fulfillment of a "normal" role in life. In the bioethical sense, handicaps, are imposed by society as an additional limitation and could be significantly reduced by a change in social attitude. (DM)
HAPLOID: A single set of chromosomes (half the full set of genetic material), present in the egg and sperm cells of animals and in the pollen cells of plants. Human beings have 23 chromosomes in their reproductive cells. Compare diploid . Haploid indicates half of total chromosome (n) of diploid number (2n) in gametes due to reduction division (meiosis).

HAPPINESS : A state of mind typically described as akin to pleasure, joy or enjoyment; however, in the language of natural science joy/pleasure are rendered transient emotional states while happiness is a continuum of pleasure or desired mood tempered by personalized values, history and a unique view of life. Thus, happiness, from the biological point of view, demands both the minds powers of reasoning and emotional intelligence the understanding and use of emotional informatitate of consciousness) can be spontaneous or artificially induced. The constitutional right of men and women to pursue their happiness means the them the highest enjoyment. (See JOY; PLEASURE; EMOTIONAL INTELLIGENCE; WELLBEING; DOPAMINE). (IP)

HARD POWER: Traditional hard powive over the long term than the use of soft power options. (See HAWK, SOFT POWER) (MP)
HARD TECHNOLOGY: Technology which is typically high in resource and energy consumption and pollution emissions, often involved in the production and manufacture of unnecessary consumer goods and dangerous applications of science. Such industries produce waste and are wasteful of resources, have unsatisfying labor-intensive working conditions, and may be dogged by ethical controversy. Hard technology is usually associated with the hard power and hard energy industries. There are opportunities forthcoming from across the board of technologies, and socially responsible corporate codes of conduct would shift heavy industry towards the sphere of soft or sustainable technologies. (See SOFT TECHNOLOGY, HARD POWER, HARD ENERGY) (MP)
HARDWARE: Mechanical and electronic equipment such as work tools, gear, gadgets and machines. Also the material (non-software) elements of computers such as keyboard, monitor, motherboard, central processing unit, discs, drives, cards and chips. (See SOFTWARE, COMPUTER) (MP)

HARM MINIMIZATION : Harm minimization is a management strategy which attempts to protect individuals or the environment from harm as the main priority ahead of political or commercial considerations. The term is most commonly used with reference to the war on drugs and the consequences of drug addiction - it implies a pragmatic acknowledgment that addicts will continue to use, and treats addiction as a medical rather than a criminal problem. Harm minimization for addicts/victims is not necessarily incompatible with zero tolerance for drug traffickers/dealers. Common harm minimization strategies include needle exchange programs, heroin trials, medically-supervised injecting rooms, methadone programs, access to counseling and medical supervision, pharmacotherapy, ecstasy testers in clubs, drug education in schools, tolerance of possession for personal use, discrimination between 'hard' and 'soft' drug categories, imprisonment only as a last resort, and drug decriminalization. (See DECRIMINALIZATION, HEROIN TRIALS, ZERO TOLERANCE). (IP+MP)
HASHISH : (Arabic: "hemp" or "dried grass") The purified exudation of resin and pollen from plants of the genus Cannabis , which forms a sticky brown substance which is smoked for its euphoric effects. Its active constituent (THC) is the same as for marijuana, and despite its illegality, hashish is very popular among young people especially in Europe. Hash or hash oil are usually smoked with tobacco to enable burning, however this habit risks nicotine addiction. (See MARIJUANA, THC). (IP+MP)
HAWK: A colloquial term for a hard-line politician or international strategist who considers that power and strength are fundamental to success in foreign relations. Hawks are characterised by a mistrustful and adversarial nature, believe in deterrence and coercion, and have a willingness to use aggressive armed conflict. The outcome of hawkish behaviour from both sides can be the self-fulfilling prophecy of war. The hawk mentality is named after predatory diurnal birds of the family Falconidae such as falcons, goshawks, kites and buzzards. Other related meanings include to hunt on the wing, a person who preys upon others, or an aggressive salesperson. (See DOVE) (MP)

HEARING : the sense that enables sound to be perceived. The ear is the organ of hearing - it is supplied by the 8th cranial nerve which is stimulated by the vibrations caused by sound waves. Every sound produces sound waves or disturbances in the air, which travel at about 340 meters per second. Because of its shape, the outer external ear concentrates the waves and directs them along the auditory meatus causing the ear drum (tympanic membrane) to vibrate. These vibrations are transmitted through the air-filled middle ear by movements of the auditory ossicles - three very small bones called the malleus, incus and stapes. The ossicles extend across the middle ear and function like a series of movable joints with each other and with the medial wall separating the middle and inner ear cavities called the oval window. It is the stapes that rocks to and fro in the oval window setting up fluid pressure waves in the internal ear which stimulate the neuroepithelial cells of the organ of hearing the cocklea from which nerve impulses pass to the hearing areas in the mid brain and cerebral cortex. It is in the brain where sound is perceived. Also situated in the internal ear are the semicircular canals - three tubes arranged so that one is stimulated in each of the three planes of space. The semicircular canals have no auditory function although they are closely associated with the cocklea - they provide information about the position of the head in space, contributing to the maintenance of equilibrium and balance. There are many diseases of the ear - prominently infections which may permanently affect hearing due to destruction of, for example, the ossicles causing conduction hearing loss or deafness, or damage to the cocklea or auditory nerve causing sensorineural hearing loss or deafness.

HEATING: Heat is a form of energy transfer. Specific heat capacity is the energy required to raise one kilogram of a substance by one Kelvin. Heat always travels from matter at a higher temperature to matter at a lower temperature. This is the basis of the solar hot water system and the heat pump. Some animals have a heat exchange system to maintain the body temperature of organs such as the brain. Heating and cooling of home and work spaces requires significant global energy resources, so building materials should be selected which are slow to transfer heat. (See TEMPERATURE) (MP)
HEAVEN: Place reserved for the righteous after death. Many religious traditions include a belief in some form of heaven, which reflects the reward in the next world that doers of good deeds will receive after death. This place is referred to in opposition to a place known as hell, which is reserved for evildoers. (see Hell). Some religious systems however, hold an alternate view, that the souls or spirits of those who have died go to a place known as "netherworld", regardless of their moral standing. (see Netherworld) Many different descriptions exist of heaven in different religious traditions, some more elaborate than others. However, these various traditions do seem to be in agreement about general ideas of heaven. For example: that heaven is a place where there is no pain or suffering, and that it is a pleasurable place, whether in spiritual or physical terms. (AG)
