The presence of smeared or unsmeared ink on the skin resulting from the writing process has been observed in a number of suicide victims who have left suicide notes. The authors report a case of a palmar "cutaneous ink sign" and discuss its forensic science import.  相似文献

Multiple deaths from argon contamination of hospital oxygen supply   总被引:1,自引:0,他引:1  
During the course of routine hospital surgical procedures, three patients lapsed into hypoxic cyanosis. Two expired immediately, another after four days of coma. Investigation of the hospital's central liquid oxygen tank revealed that it had been refilled recently and was labelled both "oxygen" and "argon." Mass spectrometric analysis of gas sampled from the questioned tank revealed a predominance of argon. A discussion of the sampling technique, method of analysis, role of the criminalist, and causes of this accident is presented.  相似文献

A conference was held at the State University of New York at Stony Brook in October 1984 to discuss the controversy concerning treatment of a newborn with severe congenital defects that became known as the Baby Jane Doe case. Fox provides some background information on the case to introduce a set of of six articles consisting of papers delivered at the conference. These articles deal with historical aspects of the treatment debate (Stanley J. Reiser), problems of clinical decision making (John M. Freeman), the legal issues involved (John A. Robertson), coverage of the case by the media (Stephen Klaidman and Tom L. Beauchamp), federal efforts to regulate the treatment of handicapped newborns (Lawrence D. Brown), and the alliance that arose between opponents of abortion and advocates of the rights of the handicapped (Constance Paige and Elisa B. Karnofsky).  相似文献

The writings of Sir Bernard Spilsbury: Part I   总被引:1,自引:0,他引:1  
This is a two-part historical feature, highlighting the rare writings of Sir Bernard Spilsbury, the recognized leader of British forensic medicine in the first half of the 20th century. Parts I and II were compiled from the publications of the Medicolegal Society of Great Britain, where Sir Bernard Spilsbury served as President in 1933. Although his profile was presented previously in this Journal (vol. 2, no. 2, 179-182, 1981), it is felt that much of Sir Bernard Spilsbury's personality comes out in his writings and recordings of his speeches in the Medicolegal Society publications. Part I includes his lecture on "The Medico-Legal Significance of Bruises," presented before the Medicolegal Society in 1938; and a short case report read before the Medicolegal Society in 1924. The subject of the case report was sudden death from inhibition. Part II will contain two papers from the Medicolegal Society publications.  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

Analyses of public policy are rooted in the economic theory of the private sector. How relevant is this approach to the public sector? Specifically, where the organization is generally viewed as a controlled variable it often exhibits the characteristics of an independent variable working to constrain the feasible solution space. An illustration of this phenomenon is discussed, using a state rehabilitation agency as the case in point. Conclusions of an analysis based mainly on maximizing the economic value of return on investment conflicted with the agency professional values of individualized client service. This external/internal value conflict led to the apparent inability of the agency to implement the study conclusions in the near term. The substance of this conflict is seen as the main problem facing many public administrators. Recognition of economic values as but one element of public agency analysis is suggested as an approach superior to sole concentration on maximization of the return on public investment. By taking a broader view, the analyst may be able to encourage more rapid implementation of his recommendations.  相似文献
