The association of simultaneous abnormalities of the thyroid and thymus is well documented, particularly in the case of Graves' disease. We present a case of a natural death following thyroid storm in which marked thymic hyperplasia was present. This finding can be helpful in determining the cause of death. 相似文献

Modern liberal theories share the idea that the state and its laws should remain neutral with respect to the varying conceptions of the good life held by individuals. This article discusses the way in which this notion of neutrality is defined and justified. Rawls's theory of justice is shown to be a prime example of such a theory. Questions are raised, however, if Rawls's theory has adequately formulated the conditions that would make it possible for each citizen to fulfill his own conception of the good. After arguing that Dworkin's solution to this problem is also problematic, it is argued that Sen's solution to the question of what conditions create neutrality shows the way ahead. 相似文献

An ultrathin-layer polyacrylamide gel isoelectric focusing technique that uses a composite of ampholytes from three commercial sources is described for subtyping esterase D. All common allelic products of esterase D were separated clearly. The technique described in this paper provides a higher conclusive call rate on known blood specimens (95.8%) and questioned bloodstains (69.7%) compared with continuous zone electrophoresis in agarose gels (89.9 and 37.6%, respectively). 相似文献

Policy analysis in the U.S. and Canada tends to follow the methods of systems analysis and takes into account variables relating to substantive matters as well as political and administrative constraints that governments face in pursuing different alternatives.Comparative analysis of the political effectiveness of the two governments in implementing the results of analysis indicates that Canada has built-in constitutional advantages. Comparative assessment of bureaucratic skills in policy analysis and policy implementation suggests that the American system is relatively weaker in terms of implementation, but relatively stronger in terms of policy analytical skills. This is followed by an assessment of the attempts made by the U.S. government to improve its policymaking structures through the setting up of the Domestic Council and the reorganized OMB, and the Canadian attempts to improve its policymaking capabilities through a reorganized Cabinet committee system and the strengthening of the Privy Council Office.The final section suggests that analysis of values and norms should be an integral part of policy analysis. The scope of policy analysis should be extended to include long-term economic and political analyses. 相似文献

As consultation-liaison psychiatrists to a cardiac transplantation team, we have observed various informed consent issues that are particularly associated with evaluation for cardiac transplantation. We discuss complicating factors that relate to each component of informed consent and present the defense mechanism of denial as a barrier to making the decision to accept or refuse transplantation. Changes in the evaluation protocol could preclude existing impediments to provision of information and patient autonomy; however, certain intrapsychic issues must be recognized as ongoing clinical realities to be addressed as the doctrine of informed consent continues to evolve. 相似文献

The microscopical examination of original surfaces on casework sized glass particles using an interference objective and the interpretation of their interferograms is discussed. To reduce subjectivity, a numerical criterion was devised to assess the curvature of glass particles and this was then applied to a survey of window, container, tableware and vehicle glasses. Objects with curved surfaces produced particles that were distinctly curved while those from surfaces of both modern and old windows were clearly identifiable as flat. Apparently flat surfaces from tableware and containers almost always yielded specimens that were detectably curved. In addition, there was no evidence that a fracture surface would be confused with an original surface from a plain flat glass.In a ‘blind’ trial to assess the interferometric routines, three examiners correctly identified flat and curved surfaces on 15 particles derived from a selection of glass objects. 相似文献
