Assessment of competency for execution presents two compelling ethical questions for mental health professionals: whether clinicians can ethically provide such assessment, and if so, how it should be done in order to maximize quality and minimize ethical conflict. In this article we address the issue of whether to participate and, if so, how. The question of whether to participate is discussed by summarizing the arguments for and against participation and offering guidelines for making a decision. The question of how to proceed is discussed in two contexts: preadjudication (before a formal decision about competency) and postadjudication (following a determination of "incompetent" and transfer of the offender to another facility for treatment and further assessment). Finally, recommendations are made regarding research that would improve the quality of execution competency assessments.  相似文献

Constitutional engineering to overcome ethnoregional cleavagesis being put to a severe test on Cyprus, where Greek and Turkishcommunities haltingly endeavor to salvage a divided state Threeyears after independence in 1960, the attempt to govern throughfunctional federalism ended in civil war. Intervention by Greeceand Turkey in 1974 resulted in a de facto partitioning of therepublic into two ethnically homogeneous areas. Under UnitedNations auspices, communal elites bargain for a consociationalsettlement, balancing national autonomy and individual rights.The solution requires international safeguards guaranteeinga new constitution and providing for "free cities" under a bicommunaladministration. Failure of the international community to actwill lead to a partitionist solution as manifested by a growingacceptance of Turkish Cypriot statehood.  相似文献

During preliminary examination of the body of a homicide victim, a peculiar red "fiber" was noticed and recovered. Initially believing this to be a carpet fiber, the item was subjected to fiber analysis. It was found to be a short coiled particle not like any known natural or synthetic fabric fiber. Subsequent examinations determined this "fiber" to be the larva of a common freshwater midge (Diptera; Chironomidae). Chironomid larvae have been observed on other bodies recovered from freshwater environments. Entomological studies of this organism have led to the conclusion that the presence of chironomid larvae indicates submersion of the body.  相似文献

So far, the law in the Federal Republic of Germany still allows the injection of fresh-cell preparations from animals as a roborant to increase the vitality of the organism and to strengthen the body's immune defense system. The use of "sicca-cell" preparations was provisionally forbidden in 1987 by the Federal Health Organization (Bundesgesundheitsamt; BGA). Prohibition of fresh-cell injections would have exceeded the authority of this office, although the same serious reservations also applied in the case of this treatment method. Several publications that have appeared since 1955 have reported serious complications of this therapy, some life-threatening and some even lethal. Two further cases are now added: (1) A woman aged 69 had been receiving treatment with cell injections for 9 years. Immediately after an injection of sicca cells she collapsed and was hospitalized; 7 days thereafter she developed an ascending paralysis with increasing inability to swallow or breathe. She died 25 days after the injection as a consequence of central and peripheral respiratory failure. Autopsy revealed the alterations typical for acute Landry-Guillain-Barré-Strohl syndrome. (2) A 76-year-old healthy woman had been receiving treatment with fresh-cell preparations for several years. After an injection of cell suspensions a painful local swelling was observed. The symptoms were interpreted as the consequence of an iatrogenic local hematoma, and repeated punctures were performed to obtain blood. The patient was transferred to a surgical department for further therapy. Two days after the injection she suddenly died with signs of acute cardiovascular failure. Autopsy revealed the signs of a fulminating clostridial infection and also the characteristic signs of Landry-Guillain-Barré syndrome with involvement of the autonomic nervous system. In both cases the development of an inflammatory process in the peripheral nervous system could be interpreted as an immune-mediated allergic disease, related to the repeated injection of heterologous antigenic material containing nervous tissues. This hypothesis would also explain the two other cases already published and would be consistent with the observed perivenous leukoencephalopathy of the central nervous system. The human disease pictures correspond to the well-established animal models of EAEM (experimental allergic encephalomyelitis) and EAN (experimental allergic neuritis). The pathogenesis is discussed; the major role of the central and peripheral nervous system is stressed, with special reference to the risk of acute autonomic failure. The need for specific autopsy techniques for the investigation of the entire nervous system, including spinal cord, roots, spinal ganglia and peripheral nerves with sympathetic chains, is raised.  相似文献
