Presented in this paper are the initial results involving the use of the nose or outer ear as temperature measurement sites to determine the postmortem period of the human corpse. Simple mathematical models for both sites are developed based on cooling curves of five corpses. Analysis of errors between actual and calculated postmortem intervals suggest that in its present form, the described methods would not be suitable for use in accurately determining the time since death of human corpses.  相似文献

Incarceration rates in the United States dramatically increased over the past several decades. This trend has drawn significant academic attention to prison overcrowding and its potential effect on inmate misconduct. The empirical relationship between inmate misconduct and overcrowding, however, is less than clear. To be sure, studies indicating positive, negative, and null relationships can all be found in the literature. The current research subjects this body of literature to a meta-analysis in an effort to: (1) clarify the direction and strength of the relationship between overcrowding and rates of prison misconduct across all studies, and (2) to uncover the degree to which variation in research outcomes can be attributed to methodological differences across studies. Results indicate that prison crowding has little substantive impact on inmate misconduct. Implications of the findings are discussed in detail.  相似文献

Those in need of employment and training programs face a variety of difficulties. Accordingly, the federal response to labor market problems has encompassed a wide range of initiatives. These include preparing people for work (through skills training, the Job Corps, work experience programs); improving the functioning of the labor market (through matching workers with jobs, establishing a minimum wage, and the Targeted Jobs Tax Credit program); and preventing discrimination. Unresolved issues in these areas are examined. They include who should be targeted for federal assistance, which levels of government can best operate programs, how public versus private efforts should be balanced, how limited resources should be distributed, and how the welfare versus work question should be resolved.  相似文献

In the following paper, I analyze the influence of advisers and domestic political factors on President Clinton's decision to use force against Slobodan Milosevic and the Serbs in Kosovo in March 1999. I present an analysis and examination of President Clinton's decision-making process, using press reports, personal speeches, etc. In other words, I attempt to trace the process by which Clinton came to the decision to use force in Yugoslavia. Specifically, using the poliheuristic theory, I argue that President Clinton's decision was influenced by noncompensatory domestic political calculations and the strong influence of his Secretary of State, Madeleine K. Albright. Examining how advisers interact with one another, their status in the advisory group, and the manner in which presidents solicit information from advisers will further our understanding of how, when, and under what conditions national security-level decision makers make decisions.  相似文献
