The more flagrant aspects of Antisocial Personality Disorder (APD), particularly criminality, are thought to diminish or "burnout" after age 30. However, empirical evidence of burnout in clinically defined groups is lacking. This study explores burnout in a cohort of forensic psychiatric patients, aged 41 to 67, with clinically diagnosed DSM-III APD (N = 39). Conviction data revealed that criminality did appear to decline from age 27 onward, but not in a straightforward manner. Further, a significant portion of the cohort remained criminally active throughout most of their adult lives. Age did not appear to interact with crime class.  相似文献

George Washington University Medical Center's Policy on decisionmaking by pregnant patients is being widely circulated by the ACLU; copies of the Policy can be obtained by calling the American Civil Liberties Union Reproductive Freedom Project. There is, of course, much disagreement over the details of the Policy; not everyone will agree with its underlying philosophy favoring maternal rights. Nevertheless, there does seem to be a consensus that wherever possible these conflicts should be resolved in accordance with previously adopted policies rather than by the courts on an ad hoc basis. Had the Policy been in place in 1987, the Carder case would probably not have been submitted to a judge in the first place, nor would Angela Carder have been forced to undergo a Caesarean section. All hospitals should consider adopting a maternal-fetal conflict policy, and those that do so should be aware of the George Washington University Medical Center Policy, whether or not they agree with its provisions. Whatever policy each hospital ultimately develops should be integrated with decisionmaking and informed consent policies already in place. The formulation and implementation of such a policy, reflecting the hospital's legal and ethical obligations to its pregnant patients, will go a long way towards preventing unnecessary resort to the courts.  相似文献

It is widely believed that electoral pressures cause legislators to favor government spending programs. This electoral theory of spending is shown to encompass two core hypotheses: (1) the electoral consequences hypothesis, which states that support for spending programs improves the representative's electoral showing; and (2) the legislator insecurity hypothesis, which states that greater electoral insecurity leads representatives to be more in favor of spending programs. A test of these ideas using spending scores for U.S. representatives in 1986 finds that neither hypothesis is supported by the data.  相似文献

When dying is all that awaits them, more and more people are choosing certain death now rather than uncertain life on medical support systems. But the decision seldom comes easy, as a Newsweek reporter discovers during three weeks with the doctors, nurses, patients and families in an intensive-care ward. A best-selling guide to suicide fires debate over when it is right to let life go--and who should make that choice when the patient no longer can.  相似文献
