The issue of whether civilly committed patients should be extended the right to accept or refuse treatment has generated much controversy and litigation during the past 15 years. In general, the current rule is that in nonemergency situations, individuals who are competent to give informed consent to treatment should be extended the right to refuse it. Obviously, the manner in which this rule is implemented partly depends on how competence to consent to treatment is defined and measured. Most researchers have implicitly assumed that an understanding of treatment information is the sole criterion of competence. It is argued that such a definition may be incomplete and is in need of reexamination. Following a review and analysis of the relevant legal and psychological literature, a comprehensive construct of competency to consent to treatment is proposed and future directions for research are discussed.  相似文献

Spleen and portal lymphnode sections from 86 drug addicts submitted for medico-legal autopsy at the Institute of Forensic Medicine in Copenhagen in the year 1979 were studied together with tissue sections from 24 "normal" persons. In 70% of the drug addicts the spleen weight was more than 200 g, and in 71% portal lymphnode hyperplasia was found. Birefringent foreign material was found in spleen tissue of drug addicts in 72% and in portal lymphnode tissue in 44%. Signs of antigen stimulation in both spleen and portal lymphnode tissue evaluated by the number of germinal centre and plasma cells were found in more than 80% of the drug addicts compared with about 20% of the "normal" persons. The results were related to anamnestic information of duration of drug abuse, to the spleen weight, to the occurrence of birefringent material and to the liver changes. Examination of lysozyme and immunoglobulin containing cells using the indirect preoxidase technique was performed in a total of 72 cases of spleen tissue, 59 cases of portal lymphnode tissue from drug addicts, 24 cases of spleen tissue and 18 of portal lymphnode tissue from "normal" persons. Lysozyme, IgM and IgG containing cells were found significantly more often among drug addicts than "normal" persons. The results indicate that the splenomegalia and the portal lymphnode hyperplasia often found in drug addicts are caused by continuous antigen stimulation due to repeated injections of various antigens.  相似文献

A split-ballot experiment shows that, when people are asked how interested they are in following political campaigns, their response depends not only on the order in which the question is asked, but also on the broader electoral context in which it is posed. When asked how interested they were in following the political campaigns immediatelyafter a question about whether or not they voted in the (1982) election, people were more likely to think they were interested in the campaign, especially if they claimed to have voted, than if they were asked about it immediatelybefore the question on whether or not they voted. This order effect, however, appears to depend onwhen the questions are asked. If asked within a few weeks after the election, there is little or no order effect. But later, as the memory of the campaign fades, the order of the questions makes a sizable difference in the results. This order effect also seems to be more pronounced among better-educated respondents, suggesting that they are more likely to feel pressured by a social norm to vote and to express an interest in political affairs, not only in real life, but in the survey interview as well. The paper concludes with a brief discussion of the implications for the design of the interview schedule used in the American National Election Studies.The research reported in this paper was supported by a grant from the National Science Foundation (SES81-11404).  相似文献

Defining risk   总被引:6,自引:0,他引:6  
Risk is the focal topic in the management of many activities and technologies. For that management to be successful, an explicit and accepted definition of the term risk is essential. Creation of that definition is a political act, expressing the definers' values regarding the relative importance of different possible adverse consequences for a particular decision. Those values, and with them the definition of risk, can change with changes in the decisionmaker, the technologies considered, or the decision problem. After a review of the sources of controversy in defining risk, a general framework is developed, showing how these value issues can be systematically addressed. As an example, the approach is applied to characterizing the risks of six competing energy technologies, the relative riskeness of which depends upon the particular definition used.  相似文献

ABSTRACT

Intimate partner violence (IPV) continues to be an urgent social problem, despite decades of intervention and prevention efforts. Restorative justice programs (e.g., victim impact panels) may be a useful addition to intimate partner violence (IPV) intervention, but it is unclear how these panels operate and to what extent they are consistent with restorative justice models. This naturalistic study of IPV surrogate impact panels used ethnographic observation of panels (n = 18), archival analysis of audience responses to the panel (N = 287), and focus groups and interviews (k = 4) with IPV survivors, an audience member, and batterer intervention providers to investigate these gaps. Findings suggest the panels manifest interactional processes consistent with restorative justice principles. Implications, limitations, and future aims of research on these panels are discussed.  相似文献
