On the ethics of extending human life: healthy people have a right to carry on livingHumanity has long demonstrated a paradoxical ambivalence concerning the extension of a healthy human lifespan. Modest health extension has been universally sought, whereas extreme health extension has been regarded as a snare and delusion—a dream beyond all others at first blush, but actually something we are better off without. The prevailing pace of biotechnological progress is bringing ever closer the day when humanity will be able (...) to act on the latter view by rejecting a clear and present opportunity for much longer healthy lives. Indeed, some biogerontologists contend that that day has already arrived, to the extent that our hesitation in embarking on a vigorous “war on ageing” is already delaying the point at which a cure for ageing will be developed. Here I consider whether our present caution concerning the wisdom of truly curing ageing is likely to survive the increased scrutiny that it will receive in coming years as a result of these technical advances. I conclude that it will not, because of its irreconcilability with values that are more deeply held by the large majority of humanity than any values that argue against the quest for a cure. I further conclude that all the major current reasons given for not curing ageing are mere crutches to help us cope with the immutability of ageing that we have been brought up to accept. Our failure to set aside such irrationality is already shortening potential longevity—quite probably of those already alive today—to a staggering degree. Once we realise this, our determination to consign human ageing to history will be second …. (shrink)
Editors’ note: These four interrelated discussions of the role of the cerebellum in coordinating emotional and higher cognitive functions developed out of a workshop presented by the four authors for the 2000 Conference of the Cognitive Science Society at the University of Pennsylvania. The four interrelated discussions explore the implications of the recent explosion of cerebellum research suggesting an expanded cerebellar role in higher cognitive functions as well as in the coordination of emotional functions with learning, logical thinking, perceptual consciousness, (...) and action planning.

T hese are indignant times. Reading news- papers, talking to friends or coworkers, we seem often to live in a state of perpetual moral outrage.The targets of our indignation depend on the particular group, religion, and political party we are associated with. If the Terry Schiavo case does not convince of you of this, take the issue of same-sex marriage. Conservatives are furious over the prospect of gays and lesbians marrying, and liberals are furious that conservatives are furious. But has (...) anyone on either side subjected their views to serious scrutiny? What’s the response, for example, when conservatives are asked exactly why gays and lesbians shouldn’t be allowed to marry? “It threatens the institution of marriage.” OK. How? “Marriage is between a man and a woman.” (Democ- rats give this answer as well.) Right, but why? “It’s unnatu- ral.” Isn’t that true of marriage in general? “Well… look… I.. (shrink)
SummaryUsing follow-up data on a sample of mothers who gave birth at a Lucknow city hospital, the family size ideals of the women were examined in relation to experienced and perceived levels of child mortality and socioeconomic and demographic characteristics.The fear of child mortality and their own experience tended to increase the size of family which the mothers considered to be ideal. Lower ideal family size was found among younger women, those who married at later ages and those currently using (...) contraception. Family size preferences were also influenced by rural/urban background, religion, caste, type of family, education, income and occupation of husband and type of housing. (shrink)
It is time for the noon conference. Your job is to impart a career-changing experience in ethics to a group of students and interns gathered from four different schools with varying curriculums in ethics. They have just finished 1½ h of didactic sessions and lunch. One third of them were on call last night. Your first job is to keep them awake. The authors argue that this “tragic case” approach to ethics education is of limited value because it limits understanding (...) of moral problems to dilemmas; negates the moral agency of the student; encourages solutions that are merely intellectual; and suggests that ethical encounters are a matter for experts. The authors propose an alternative that focuses on three issues: the provider-patient relationship, the relationships between providers in the everyday world of health work and, the social position of healthcare providers in society. In this approach, teachers are not experts but more like guides on a journey who help students to learn that much of ethical practice comprises living through difficult situations of caring for vulnerable others and who help students to navigate some of these difficulties.

The Protein Ontology (PRO) provides a formal, logically-based classification of specific protein classes including structured representations of protein isoforms, variants and modified forms. Initially focused on proteins found in human, mouse and Escherichia coli, PRO now includes representations of protein complexes. The PRO Consortium works in concert with the developers of other biomedical ontologies and protein knowledge bases to provide the ability to formally organize and integrate representations of precise protein forms so as to enhance accessibility to results of protein (...) research. PRO (http://pir.georgetown.edu/pro) is part of the Open Biomedical Ontologies (OBO) Foundry. (shrink)
