Sudden death during sexual activity is generally caused by natural diseases, like coronary sclerosis and myocardial infarction. Only a few case reports describe outer circumstances as responsible for the fatal outcome. This is a case report of a couple that drowned within a car sinking into a river. The extraordinary scenery led to the supposition that sexual intercourse was involved with these fatalities. The victims--a young woman and a young man, both had children, the man was married--kept up an extramarital liaison. Both were reported missing by their relatives days before the corpses could be recovered.  相似文献

The authors report on the death of a 25-year-old man due to electric current in prison, which was not recognized at first. The fatal accident was caused by a self-made electric kettle. The only electrothermal skin lesions were some pinhead-sized electric marks on the left thumb. Careful external inspection of the body in combination with an analysis of the conductor material (aluminium) by means of atomic absorption spectrometry (AAS) revealed the cause of death and the source of accidental electrocution.  相似文献

Conclusion Historically, the conception of good faith has been shaped by a variety of forces — political, mercantile and religious among them. Similarly, the CISG also treats the duty of good faith in a holistic manner; rather that attempt to explicitly define the good faith obligation in isolated provisions, the drafters of the CISG marked good faith as an integral and pervasive requirement. The drafters rightly understood that unfair dealing is best recognized in specific factual scenarios; judges and arbitrators will know bad faith when they see it. Thus, the drafters designed a systematic approach to international sales transactions with the assumption that the basic obligations of good faith and fair dealing are understood by the parties. In so doing, they have provided a source of confidence to traders who, due to the nature of the modern international marketplace, must forge their agreements fax-to-fax rather than face-to-face.Law Clerk, Allan Kanner & Associates, New Orleans, Louisiana.

The National Health Service is a system designed to bring about a rational use and distribution of resources yet which largely ignores the contribution of the research community. With a relatively closed health policy arena, there are few customers for policy-oriented research. With responsibility for funding research concentrated at the center and responsibility for delivering services at the periphery, the research community finds itself in limbo. In comparison to both the U.S. and Canada, Britain therefore offers an example of research both underfinanced and undervalued. However, research has made some significant contributions in areas where there has been a perceived use for its findings to support service developments. And the changes now being introduced in Britain's NHS are likely to create a new market for research as the system adopts some North American ideas and becomes less consensual and more pluralistic.  相似文献

Israeli academics disagree with respect to the scope of the change that has transpired within the PLO. Proponents of the first approach are convinced that leaders in the PLO mainstream have indeed changed the organization's basic orientation. Advocates of the second orientation, on the other hand, contend that the putative transition does not represent anything more than the potential for real revision of historic objectives. In this article, I outline the broad theoretical framework within which this interpretative argument has taken place. After elaborating the theoretical framework, I propose a methodological direction which differs from the one traced by these two opposite approaches. I claim that an arbitration mechanism that negotiates a middle ground between the fundamental and operative ideology has developed within the PLO. These three dimensions exist within the PLO at one and the same time; and since its crystallization in the mid‐1980s, the middle ground has become the dimension that dominates the PLO's activities.  相似文献

The current clandestine methodology for the manufacture of illicit cocaine hydrochloride utilizes microwave heating in order to dry the finished product. This study addresses the effects this step has on the occluded solvents present in newly prepared cocaine hydrochloride. Nine 1-kilogram-sized batches of cocaine hydrochloride were prepared from cocaine base using a variety of solvents or solvent mixtures commonly utilized in clandestine laboratories, pressed into bricks, and submitted to microwave heating. Residual solvents were qualitatively and quantitatively monitored before, during, and following the microwaving step by static headspace-gas chromatography-mass spectrometry. All solvents used in the conversion process were easily detected in the bricks even after extensive irradiation, confirming that occluded solvents are extremely resistant to removal by microwave heating. Qualitative and quantitative data corresponding to the residual solvents in the prepared cocaine hydrochloride bricks are presented.  相似文献

Despite evidence that early care and education services benefit at-risk children, they remain underutilized by families in the child welfare system. This article describes two training programs developed to educate child welfare and childcare/preschool staff about the importance of early care and education for maltreated children and how to access these services. A combined total of 274 trainees completed knowledge tests about this topic and significant pre- to post-training improvements indicate that both training programs effectively increased participants' knowledge about this important topic. In addition, improvement in self-assessed competency was observed for participants in one program, and positive changes in attitudes and anticipated practice behavior regarding childcare for foster children were observed among participants in the other.  相似文献
