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

随着互联网和人工智能的快速发展,恐怖主义活动方式变得更为隐秘。网络恐怖主义活动空间从表网的在线社区与视频分享平台转向暗网黑市交易和暗网论坛。针对暗网节点通信和交易信息高度匿名等特点,相应的反恐工作需要采取新的技术手段,以深度切入恐怖分子用于扩大影响的暗网空间。为此,可以设计和优化专门适用于暗网的聚焦爬虫工具,挖掘恐怖主义活动信息;可以搭建涉恐事件数据模型,分析恐怖组织可能的线下攻击手段;可以利用社会网络分析和超链接分析方法,定位暗网内恐怖主义隐蔽社区和危险用户集群。通过准确把握暗网中的匿名恐怖主义活动规律,抓住安全监控与防范的重点、难点,综合施策,以及适时制定和精准实施反恐网络安全策略,能够最大限度遏制暗网恐怖主义的危害,保护国家安全和人民利益。  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
