AAT:
or alpha-1-antitrypsin. A protein which in deficiency causes a lung
disease called emphysema, due to altered regulation of the enzyme.
AAT can be produced through genetic technology in the milk of sheep,
by transfer of the human gene to the sheep. One sheep made to produce
AAT is called Tracy. (JA)
ABM:
Anti-Ballistic Missile.

ABNORMALITY:
Something that is not the normal. This term is used in the debate
over fetal diagnosis in the selection of embryos or fetuses that
have a trait that will cause disease. (See PRENATAL DIAGNOSIS) (DM)
ABORIGINAL:
Original inhabitants of those parts of the world that were conquered
and colonized with an overwhelming thrust aside of these populations
to relatively isolated regions. These peoples are now called aboriginals,
and are still found in many parts of the world: America (see AMERINDIAN),
Australia (see AUSTRALIAN ABORIGINAL and Torres Straight Islander
peoples), Guinea (Papuans), New Zealand (Maoris), etc. The natural
admixture with the new settlers has been partially or totally absent,
leaving a native community virtually untouched in biological and
cultural terms. (See also AUSTRALIAN ABORIGINAL & INDIGENOUS)
(GK)
ABORTION:
The spontaneous or deliberate termination of pregnancy before the
embryo or fetus has been born, or is viable outside the womb. Should
be restricted to refer to the termination of a pregnancy after implantation
of the embryo into the mother. Many countries have laws restricting
access of mothers to abort their fetus. Some countries prohibit
abortion outright, other countries allow for a range of conditions
affecting the mother, and/or for fetal indications. Spontaneous
abortions in the first trimester are due in 50% of the cases to
chromosomal abnormalities (26% are due to trisomies, 10% to X monosomies,
and the rest to triploidies, tetraploidies, or structural abnormalities).
Moral issues have been extensively discussed for several millenium
without resolution. (DM, FL, GK)
ABORTION
ON DEMAND:
Readily available legalized abortion, including abortion for personal
or social reasons. (DM)
ABORTION
IN JUDAISM:
An extremely early Jewish source, the Mishna, (Tractate
Ohalot
not only allows abortion, but requires it when in cases when pregnancy
threatens the life of the mother. The crucial issue according to
the Mishna, is that "Her life is more important than its life."
Among current authorities, there is no debate about the fact that
abortion is sometimes permitted and required. The only debate is
over the specific circumstances in which abortion would be indicated.
The more strict, inspired by the writings of the late Rabbi Moshe
Feinstein, allow for abortion only when the life of the mother is
in clear and certain danger. More liberal orthodox rabbis, inspired
by the views of Rabbi Eliezer Waldenberg, allow for abortion when
the mother's life is in probable but not certain danger, when
her health although not her life is in danger, when her mental although
not her physical health is in danger, and even when the mother is
a married woman who became pregnant because of an extra-marital
relationship. (FL)

ABSTRACT
THOUGHT:
A general concept, as opposed to a thought about a particular individual.
PLATO (q.v.) and his followers believed that while an imagination
or memory about an individual object or person might contain palpable
characteristics like colour, sound, taste, smell or tactile feeling,
abstract thoughts are totally spiritual with no palpable content.
But David HUME (q.v.) claimed that he had never experienced any
such "spiritual and refined perceptions", and that all
of his thoughts were really only particular images which might nonetheless
be used in one's thinking to represent a large class of things.
(In thinking about all dogs, for example, I might already have an
image of a particular dog in my mind.)
Abstract thinking is really the same as thinking
in generalizations, not thinking about "this particular cancer
patient", for example, but thinking about "all (or most)
cancer patients". Thinking in generalizations, or "epidemiologically",
is a characteristic of Western conventional medicine. A new treatment
is not accepted to replace an old one unless it works better in
a "statistically significant" percentage of the tested
population. Some Asian medical systems, like Ayurvedic and Chinese,
are much more individualistic, and the doctor will prescribe a treatment
only after observing many different characteristics of the individual
patient. This makes it difficult to carry out conventional clinical
trials on Asian medicine. Medical genetics, which is learning to
spot genetically determined differences in patients' responses
to drugs and environmental influences, may however cause a "paradigm
shift" and make scientific but individualized medicine possible.
(FL)
ABUSE:
(Latin
abuti
'to waste'). 1. the intentional or unintentional misuse
of substances, drugs, equipment, programs and so forth 2. to physically
or verbally attack or maltreat another; for example, an abused person
is an individual who has been harmed by another person or situation.
(See CHILD ABUSE; DRUG ABUSE; ELDER ABUSE) (IP)

ACCELERATING PACE OF CHANGE:
Technological innovation,
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.
(See
TECHNOLOGY, MOORES LAW, FUTUROLOGY, CHANGE) (MP)
ACCEPTANCE:
See PUBLIC ACCEPTANCE.
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)
ACCOUNTABLE:
Emphasized liability for something of value either contractually
or because of ones position of responsibility (see ACCOUNTABILITY,
RESPONSIBLE) (IP)
ACCOUNTABILITY:
Responsibility for explaining or justifying one's conduct to
the public or to one's superiors. Social responsibility includes
the obligations of an individual or institution to society. (see
RESPONSIBLE) (DM)
 |
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. (See
Brain Neurotransmitters; TOXICOLOGY; DOPAMINE; POISON HEMLOCK).

ACF:
Australian Conservation Foundation.
ACGT:
UK Advisory Committee on Genetic Testing, United Kingdom. It terms
of reference are (1) to provide advice to Ministers on developments
in testing for genetic disorders; (2) to advise on testing individuals
for genetic disorders taking account of ethical, social and scientific
aspects; and (3) to establish requirements, especially in respect
of efficacy and product information, to be met by manufacturers
and suppliers of genetic tests. (JA)

ACHIEVEMENT:
The successful completion of tasks, plans and responsibilities,
or other accomplishments whether from inspiration, heroism or hard
work. Achievements may be assigned by the self or motivated by a
teacher, and the goals realized may be personal or professional.
The achievements of people are commonly compared by society using
age-related tests in school, and experience-related tests in the
workplace. (MP)
ACID:
1. A compound that yields hydrogen ions (H+)
when dissociated in solution, reacts with bases to form salts and
tastes sour due to its low pH value 2. Street slang for the hallucinogenic
mood-altering drug lysergic acid diethylamide (LSD), for example,
"to
drop acid"
meaning to take LSD. (See ACID SOILS, LSD) (IP+MP)
ACNFP:
Advisory Committee on Novel Foods and Processes of GM Food.

ACT:
Advanced Cell Technology is a biotechnology organization and is
located in Massachusetts in USA. (JA).
ACT CONSEQUENTIALISM:
See UTILITARIANISM.
ACT
OF GOD:
See ACT OF NATURE.
ACT
OF NATURE:
a misadventure or casualty which is said to be caused by an 'Act
of God'; that is, occasioned exclusively by forces of nature
without the intervention of any human agency. An act of nature may
be any accident produced by any physical force such as lighting
strikes, tempests, perils of the seas, tornados, earthquakes etc.
(See ACT OF PROVIDENCE) (IP)
ACT
OF PARLIAMENT:
a statute or law made by the sovereign with the advice and consent
of those assembled in parliament. Acts of parliament form the written
laws of the nation and are of three kinds: public, local or special,
private or personal. The validity of a statute cannot be questioned
in court. (IP)
ACT
OF PROVIDENCE:
an uncontrollable accident against which ordinary experience or
foresight could not guard. (See ACT OF NATURE) (IP)

ACTIVE
EUGENICS:

ACTIVE
EUTHANASIA:
See EUTHANASIA.
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 environmental
activists - companies will often 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’.
Sometimes activism can spill over, such as the riots at the anti-globalization
protests of the 1999 Seattle World Trade Organization meeting. Non-violent
direct action must be recommended, as violent activism undermines
the cause and is sometimes branded ‘ecoterrorism’. Quite
the reverse, most protest and activism works towards human rights
and socio-ecological harmony, including the peace movement, civil
rights movement and green movement. (See PROTEST, NONVIOLENT RESISTANCE,
CIVIL DISOBEDIENCE, DIRECT ACTION, DISSENT, INDUSTRIAL ACTION, CULTURE
JAMMING, REVOLUTIONARY, ECOTERRORISM, HACKTIVISM, ANTI-GLOBALIZATION

ACTIVITY ANOREXIA:
See ANOREXIA ATHLETICA.
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)
ADA:
American Disability Act of 1990 which prohibits discrimination in
the workplace against a handicapped person who is otherwise qualified.
The act came into effect from 1992. (JA).
ADA DEFICIENCY:
Adenosime deaminase deficiency is a rare genetic disease that is
caused by lack of functional adenosine deaminase enzyme, that causes
an immunodeficiency disease. In 1990 it was the target disease of
the first attempts at human gene therapy, and has been one of the
few genetic diseases claimed to be cured by gene therapy (2001).
(See HUMAN GENE THERAPY) (DM)
ADAM
AND EVE:
See GENESIS and ORIGINAL SIN.
ADAPT:
(Latin:
adapt’re
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. (See ADAPT, ADAPTIVE THINKING,
STRATEGIC MANAGEMENT, PRECAUTIONARY PRINCIPLE) (MP)
ADAPTIVE
RADIATION:
The evolutionary divergence of a lineage of organisms into different
phenotypes. (See RADIATION, EVOLUTION, NATURAL SELECTION) (MP)
ADAPTIVE
THINKING:
The ability to change ones mind on the basis of newcertainty,
is able to say 'I don't know', and is willing to
revise beliefs and opinions. (See ADAPT, ADAPTATION, ADAPTIVE MANAGEMENT)
(MP)
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.
(see FETAL ALCOHOL SYNDROME; DRUG TOLERANCE; INDIVIDUAL DRUG ENTRIES;
INTERNET ADDICTION; GAMBLING ADDICTION) (IP)
ADENINE:
Commonly abbreviated as A, one of four nitrogen containing bases
in nucleotides, a component of DNA and RNA. (JA)
ADENOSINE
DEAMINASE DEFICIENCY:
See ADA DEFICIENCY.
ADHD:
See ATTENTION DEFICIT HYPERACTIVITY DISORDER.
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)
ADVERSARIAL SYSTEM:
A system or process which relies on two or more opposing sides to
resolve conflict and make decisions. Adversarial government systems
and legal process may engender conflict, bickering and zero-sum
bitternl iterations and destructive criticism of theories are the
backbone of progress in science. (See COLLABORATION, TEAMWORK, CONFLICT
RESOLUTION, GAME THEORY) (MP)
ADVERSE
EFFECT:
a clinical or perceived undesired effect of a chemical or physical
agent. (SG2)
ADVISORY COMMITTEES:
Committees or commissions set up to advise governmental bodies or
other institutions on public policy. (See also ETHICS COMMITTEES
, REVIEW COMMITTEES) (DM)
ADVISORY
COMMITTEE ON GENETIC TESTING:
See ACGT (UK).
AEROBE:
(Greek:
aer
'air')
Any microorganism that lives and grows on free oxygen (Greek:
aer
air +
bios
life). (See ANAEROBE) (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)
AFFECT:
A transitive verb meaning to influence (act on, move, impress) to
produce change in something (e.g. in a system, disease, person).
To affect is to produce an effect. (See CAUSATION, EFFECT) (MP)
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.
(See MINORITY GROUPS, ACTIVISM) (MP)
AFLOTOXINS:
Fungal toxins,
Aspergillus flavus,
of peanut, corn toxins have carcinogenic substances. (JA)
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.
AGE DISTRIBUTION:
The demography of the comparative ages of individuals in a population,
commonly graphed as a ‘population pyramid’. 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 distribution helps elucidate
population trends, cohorts, generations, immigrations, emigrations,
birth rates and mortality rates. (See AGE/SEX PYRAMID, POPULATION
DISTRIBUTION, DEMOGRAPHY, COHORT, 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)
AGED:
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.
(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:

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. (See AGRO-BIOTECHNOLOGY, AGRICULTURE) (IP & MP)
AHIMSA:
The South Asian cultural ideal of being non violent. Mahatma Gandhi
used the principle of non violence in his struggle for freedom from
foreign occupation of India. (JA)
AI:
See ARTIFICIAL INSEMINATION or ARTIFICIAL INTELLIGENCE.
AID:
Artificial insemination using donor sperm. (see ARTIFICIAL INSEMINATION)
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.

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.
(see ALCOHOLISM; ETHYL ALCOHOL; FETAL ALCOHOL SYNDROME) (IP)
ALCOHOLISM:
severe dependency on alcohol intake associated with cumulative destructive
physical, reproductive and behavioral effects. The most serious
medical consequences are central nervous system deterioration, liver
cirrhosis and adverse reproductive effects. Alcohol abuse is the
overuse of alcohol to the extent of habituation, dependence, or
addiction. (see ALCOHOLICS ANONYMOUS (AA); FETAL ALCOHOL SYNDROME)
(IP, DM)
ALCOHOLICS
ANONYMOUS (AA):
an international nonprofit organization, founded in 1935, made up

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)
ALIEN LIFE:
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)

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)

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,

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

(MP)
ALTERNATIVE THERAPIES:
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.
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:
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 21st
, 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).
AMNIOTIC FLUID:
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

(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:
(Greek:
an +
aer
"without air" +
bios
"life") Any
species which generally lives in the absence of oxygen.
(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

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,

ANALYTIC PHILOSOPHY:
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.
ANGER:
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,

ÅNGSTROM:
A unit of length defined as 10
-10
meter. Å 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:
“nulus
'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:

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.

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. (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)

UNIVERSE THEORY, ANTHROPOCENTRIC) (MP)
ANTHROPOCENTRIC:
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
th
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)

Combining prefix denoting against, reverse or
in opposition to. (See ANTE-, MAL-, PSEUDO-, META-) (MP)
ANTI-ANXIETY DRUGS:
See ANXIOLYTICS and ANXIETY.
ANTIBIOTIC:
(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

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,

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

ANTIHISTAMINES:
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

ANTI-SEMITISM:
Semites are a loosely interrelated group of populations speaking
similar languages, including Hebrew, Arabic, and such Ethiopian

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.

ANXIETY:
(Latin
anxietas)
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
life’s essential values and goals. Anxiety disorders are complex
and may take different forms (generalized anxiety, separation anxiety,
panic anxiety, situational anxiety, for example) with separate etiological
variables. Anti-anxiety drugs (anxiolytics), by helping to control
the physiological symptoms, provide relief. The definitive treatment,
however, rests with addressing the underlying cause(s) for example
changes in health, self-concept or environment, maturational crises
or subconscious conflicts. Anxiety differs from depression, but
is typically linked to all forms of depressive illness. (See 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

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,

(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.

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)
AQUINAS, THOMAS:
(1225? -1274) The greatest of the medieval
Scholastic
philosophers, canonised as Saint Thomas by the Catholic Church.
His philosophy is called
Thomism
. The
Scholastics
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)
ARBITRARY:
Uncertain; random; accidental; discretionary; outside of central
relevance to the methodology, law or principle, therefore accepting
of individual choice and subjectivity. (MP)
ARBITRATION:
The hearing and resolution of a dispute by a person or legal body
(arbitrator) chosen by the disputing parties or appointed by government
statute. (See MEDIATION, NEGOTIATION, FACILITATION, DISPUTE) (MP)

ARETAIC
ETHICS:
The principle of centrality of employing moral agents as the basis

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. Numbers may be manipulated to advantage from one form
to another, for example, fractions to decimals. (See ALGEBRA, ANALYSIS
OF VARIANCE, SCIENTIFIC METHOD, STATISTIC) (IP)

ARTHROPODA:
Name of a phylum in the animal kingdom. Animals (arthropods) that
have joined appendages. E.g. Fly, Crabs, Millipedes, Scorpions etc.
(JA)
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.
(See ARTIFICIAL LIFE, GENETIC ENGINEERING) (MP)
ARTIFICIAL
FEEDING:
Feeding other than by mouth. The terms, Enteral feeding, Parenteral
feeding, and Tube feeding are used.
(DM)
ARTIFICIAL HABITAT:
Artificial habitat is sometimes used in an extreme envich
included humansearch on the safety of artificial habitats will be
required before colonization of the moon becomes realistic. (See
HABITAT, BIOSPHERE 2 PROJECT, INTERNATIONAL SPACE STATION) (MP)
ARTIFICIAL HYMEN:
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 Volap¸k (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:
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
Matrix
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
like
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). (See ARTIFICIAL LIFE, EXPERT SYSTEM, ROBOTICS, ROBOT
ETHICS, INTELLIGENCE, CYBORG, BIONICS, BIG BROTHER, DEEP BLUE, TURING
TEST) (MP)
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 GenghisÖ 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. (See
LIFE, ARTIFICIAL INTELLIGENCE, INTELLIGENT AGENT, CELLULAR AUTOMATA,
COMPUTER VIRUS, WORM, ROBOTICS, ROBOT BUSH) (MP)
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. (See

ASEXUAL
REPRODUCTION:
Reproduction of organisms by purely vegetative means without the
function and interaction of the two sexes. Examples of commonly
asexually reproduced plants are roses, peach trees, and lilies.
All plants can produce vegetatively, but many normally use sexual
reproduction. (DM+IP)
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)
ASOCIAL:
Asocial behavior refers to withdrawal from society, including inhibition,
inconsideration and avoidance of others. It may often be accompanied
by anxiety and depression. (See ANTISOCIAL) (MP)
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. (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 (C9
H8
O4)
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)

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. ( See CORTISOL)

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
135Uranium
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
AURORAS, HALOES)
(FL)
AURORAS: (Latin: Auror 'Goddess of Dawn').
Also known as the Northern and Southern Lights. The aurora lights
form when solar particles and magnetic fields hit the Earth’s
magnetic field, speeding up electically charged particles trapped
within. These crash into the upper atmosphere over polar regions,
creating a ghostly, multicolored glow. (See AURA, HALOES) (IP)

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

AUSTRALASIA:
The land masses of Oceania in the South Pacific together with Australia,
New Zealand, New Guinea and associated islands (Latin
australis
= southern + Asia). (IP)
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.

years ago. It exhibits bipedalism, has protruding jaws and a small
brain cavity. When compared to the bigger cranial cavity of Modern
Homo sapiens.

AUTHORITARIAN:
Demanding total obedience and refusing to allow people freedom to
act as they wish. (DM)
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. Autografting
is typically used in medical surgery such as the replacement of
lost skin in cases of severe burns, or in plastic surgery such as
the remodeling of facial features. (See ALLOGRAFT, XENOGRAFT) (IP)
AUTOIMMUNE
DISEASE:
A disorder in which the immune system fails to recognize self and
directs an immune response against its own body tissues. Among human
autoimmune diseases in which components of the body are attacked
by its own immune system are rheumatic fever, rheumatoid arthritis,
ulcerative colitis and myasthenia gravis (muscle weakness).
(IP)
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)
AUTOMATON:
(Greek:
automatos
'acting of itself')
An early term for a mechanical device or simple robot able to self-perform
or imitate real-life actions. Sometimes used as derogatory for a
person who goes through life with a mechanically predictable and
ordinary routine. Descartes argued that animals may also be mere
automata, wholly governed by the laws of physics. (See ROBOT, CELLULAR
AUTOMATA) (MP)
AUTONOMIC
NERVOUS SYSTEM:
The motor nerve fibers supplying the glands, organs and smooth muscles
of the vertebrate body, including the sympathetic and parasympathetic
nervous systems; the elements of the nervous system which automatically
manage the functions of internal organs such as pulse and digestion.
(See CENTRAL NERVOUS SYSTEM) (MP)
AUTONOMOUS:
Ability to operate on ones own. (See AUTONOMY) (MP)
AUTONOMOUS UNDERWATER VEHICLE:
See AQUABOT.
AUTONOMOUS WEAPONS:
An ethically perilous form of missiles and other robotic weapons,
endowed with onboard ‘intelligence’ to locate themselves,
navigate and destroy the enemy without direct external guidance
or tele-operation from humans. Euphemistically called ‘smart’
weapons, they may in fact not be very smart - either in the immediate
sense of killing, or in the broader philosophical sense of combining
artificial intelligence with weapon systems. (See VIRTUAL WARFARE,
ROBOTICS, AUTOMATIC WEAPONS, MISSILES) (MP)
AUTONOMY:
(Greek:
autos
'self' +
nomos
'law')
The governing of one's self according to one's own system
of morals and beliefs. 1.
the absence of external constraint and a positive power of self-determination
often applied to the right of personal freedom in actions, choices,
beliefs and preferences. Bioethics uses autonomy as self rule, though
the term self-love has been 2. in political philosophy the right
of self-government of community, group or state, to formulate and
enforce its own laws, policies and affairs; being independently
accountable 3. biological organic independence evolved and controlled
by natural laws and not subject to any other. (IP+DM)
AUTOPSY:

AUTOSOMAL
RECESSIVE DISORDERS: Disorders,
where for a person to be affected, a mutation has to be inherited

only have a single copy of the mutant gene. Recessive disorders
commonly have onset in childhood and include cystic fibrosis, sickle
cell disease and thalassaemia. (JA)
AUTOSOMAL
DOMINANT DISORDERS:
Disorders where inheritance of a mutation from one parent only (or
