A review of the way physician-assisted suicide (PAS) is being addressed in the United States reveals three models, each functioning out of distinctive concepts of autonomy: (1) litigation, which utilizes philosophical autonomy; (2) legislation, which utilizes political autonomy; and (3) act of conscience by a physician, which utilizes consumer autonomy. Each model raises a correspondingly distinct set of ethical questions and challenges centered around their point of reference-the judicial system, voters, or the doctor-patient relationship. In the end, however, efforts to resolve the challenge of PAS will falter if they do not go beyond these models of autonomy. Religious institutions offer a more constructive setting for facing the life and death decisionmaking of PAS. The challenge for religion is to address PAS in solidarity with sufferers, physicians, and the community, rather than retreating into iconoclastic dogmas.  相似文献

Whereas the introduction of new technologies previously has raised the ethical question of who ought to have access to a new procedure or device, genetic testing technology raises the new ethical question of to whom access to a new technology ought to be limited. In this article we discuss the implications of employers and private health insurance companies having access to genetic testing technology. Although there may be legitimate business interests in allowing employers and insurers to conduct genetic screening, there are other valid societal interests in regulating or limiting the use of this technology by third parties. Public policy developed in the area of new genetic technology must reflect such interests.  相似文献

An analysis of the field of higher education reveals a surprisingly large number of classification errors within the (US) National Taxonomy of Exempt Entities database. Of the nearly 4,000 non-profit entities coded within the universe of institutions of higher education, we estimate that approximately 60 per cent were incorrectly included (Type II errors). Institutions incorrectly excluded from the higher education universe (Type I errors) represent roughly 10 per cent of the institutions coded correctly. These errors result primarily from assigning codes on the basis of the names of organisations (for example, College Park Towers is classified as a college, when it is in fact a housing complex for senior citizens) and from trying too hard to assign codes in ambiguous situations. The consequences can be significant for the users of these data, and we recommend raising bright warning flags while simultaneously enlisting the help of the entire non-profit sector in improving the classification coding process.The authors are with The Andrew W. Mellon Foundation. In addition to our colleagues on the staff of the Foundation, we wish to thank Helmut Anheier, Ted Bozovich, Harvey Dale, Virginia Hodgkinson, Stephen Noga and Christopher Toppe for helpful suggestions.  相似文献

Job satisfaction surveys among physicians, a recent phenomenon, are a very important managerial tool to determine the work motivation needs of physician-employees. The first MD Job Survey was done in 1984 by Lichtenstein on physicians employed by prisons. The largest survey of salaried physicians to date has been the 1987 Health Services Research Center of Chapel Hill survey of physicians employed in group practices. Currently, individual group practices are surveying their staffs with job satisfaction questions in order to enhance the work environment.  相似文献

5he purpose of this study was to determine whether or not suspected variables affected a surgery clerk's chances of being awarded an honor rating. Findings indicated a significant relationship between a student receiving an honor rating and his or her preceptor's predetermined level of student advocacy, the number of completed patient interview and physical examination write-ups, and final examination scores. There was no significant relationship found between honor ratings and the preceptor's status, the sequence in which the student was discussed or the length of time spent discussing the student at the final evaluation meeting, or the number of clinical faculty present at the meeting. These results lend support to the faculty forum evaluation approach, but suggest a need for further scrutiny of some influencing variables to ensure all students are fairly considered and honor ratings judiciously awarded.  相似文献

"Although the flow of human beings between countries and continents has marked the behaviours of populations for centuries, present international migration is clearly characterized by a number of new factors which make it distinct from international movements of people in the past. This paper aims to identify such new factors relating to the underlying reasons for the international mobility of people, including the motivations of the individuals concerned, and attempts to examine the consequences as they are being faced by the individuals involved, the countries concerned and--in more general terms--the international community."
