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

A dissecting intramural haematoma of the coronary artery is an infrequent cause of sudden and unexpected death. Most cases are women and in a significant number of these women, the haematoma occurred at term to 80 days postpartum. Because the intimal rupture and communication with the lumen were not found in most of the cases, the site of rupture has been considered to be a vasa vasorum. The authors report on a case of one woman who was at a later postpartum period (106 days). The microscopic finding of the dissected coronary artery revealed two intimal tears in a section. The case showed that the dissecting intramural haematoma of the coronary artery is caused not only by the rupture of the vasa vasorum but also by the rupture of the intima.  相似文献

A final course, or project is a standard requirement in Master of Public Administration (MPA) programs. This requirement is intended to permit the student to demonstrate advanced ability in the discipline. This article examines one such course at Florida State University. The course included readings, exercises, oral presentations, and a written report. This author assesses the merits and drawbacks of the course as well as notes the unintended consequences that resulted. In concluding the article, the author makes several recommendations for future courses based on the experiences gained in the Florida state model.  相似文献

Abstract
The author presents a relatively formal theory of the rule of law which includes three basic components: conceptual, institutional and axiological. He then emphasizes the differences between a formal and a substantive theory of the rule of law and highlights the advantages and limits of the former. Finally, the author indicates the importance of this type of theory, namely the values it implies such as predictability, justified reliance, autonomous choice, minimization of disputes and legitimacy.**  相似文献

The manner in which agenda change occurs demonstrates how institutional arrangements influence agenda priorities in the Supreme Court and Courts of Appeals. A neo-institutional theoretic perspective is employed to examine the dynamics of agenda formation in these courts. The article finds that the Supreme Court's agenda choices influence the decisions of litigants, interest groups, and lawyers to appeal certain cases to the Courts of Appeals. While the Supreme Court's agenda primarily is influenced by internal factors, it is constrained by agenda changes in the appeals courts. Critically, it is shown that these federal appellate courts exist within an endogenous system with respect to agenda formation, as both courts respond to agenda changes made in the other over time.  相似文献
