With increasing frequency, relatively small, fragmentary evidence thought to be osseous or dental tissue of human origin is submitted to the forensic laboratory for DNA analysis with the request for positive identification. Prior to performing DNA analysis, however, it is prudent to first perform a presumptive test or "screen" to determine whether the questioned material may be eliminated from further consideration. When material is shown not to be consistent with bone/teeth, DNA testing is not performed. When such determinations cannot be made from gross morphological features, elemental analysis can be indicative. This presumptive test is made possible by applying scanning electron microscopy/energy dispersive X-ray spectroscopy (SEM/EDS) in conjunction with an X-ray spectral database recently developed by the FBI laboratory. This database includes spectra for many different materials including known examples of bone and tooth from many different contexts and representing the full range of taphonomic conditions. Results of SEM/EDS analysis of evidence can be compared to these standards to determine if they are consistent with bone and/or tooth and, if not, then what the material might represent. Analysis suggests that although the proportions and amounts of calcium and phosphorus are particularly important in differentiating bone and tooth from other materials, other minor differences in spectral profile can also provide significant discrimination. Analysis enables bone and tooth to be successfully distinguished from other materials in most cases. Exceptions appear to be ivory, mineral apatite, and perhaps some types of corals. 相似文献

The authors evaluated the usefulness of the postmortem biochemical analysis of ionic ratios in different parts of the heart and their relation to cardiac damage caused by chest trauma, as observed by anatomopathologic study. Fifty-nine 59 cases were studied, selected from routine necropsies, and samples were taken from different sites of cardiac tissue. The cause of death was trauma in 40 cases and nontraumatic causes in 19 cases. The object of this study was to analyze the levels of Na+, K+, Ca+2, Mg+2, and Zn+2 in different zones of the heart, and the relationship between intracellular and extracellular ion ratios and the different causes of death and any anatomopathologic alterations observed. The biochemical tests revealed a possible relation between the ionic values and cause of death. Alterations in cell membrane permeability and corresponding modification of the ionic ratios were produced earlier than histologic alterations, which need longer to establish themselves whether or not they follow a traumatic process. 相似文献

Public management scholars often claim that agency competition provides an effective institutional check on monopoly authority, and hence, leads to improvement of administrative performance in public sector agencies. This logic was central for creating the Congressional Budget Office (CBO) in 1975 to challenge the policy information provided by the Office of Management and Budget (OMB). We challenge this conventional wisdom by demonstrating that CBO has failed to enhance the quality of U.S. fiscal policy analysis on its own terms; nor has it spurred improvements in OMB's performance. Our empirical results indicate that the quality of OMB's fiscal projections has often deteriorated since the establishment of CBO as a rival bureau. We also show that both public and private information is being shared by these agencies to produce a similar caliber of task outputs. The broader implications of our study indicate that although politicians face incentives to employ agency competition in governmental settings, this type of bureaucratic strategy does not necessarily enhance the quality of administrative performance. © 2006 by the Association for Public Policy Analysis and Management 相似文献

The author draws on the Brazilian public administration literature to discuss the conflict between the need to remain open to lessons from elsewhere, while at the same time remaining grounded in a particular local context. The article begins by presenting calls by a number of Brazilian public administration scholars for what might be termed an "administrative particularism," or an assertion that universal lessons do not apply in the discipline. This is followed by a discussion of the challenges that these and other Brazilian public administration scholars identify. Further discussion will suggest these challenges, and many of the solutions most commonly offered for them, imply that, far from a uniquely Brazilian public administration, the country seeks to move closer to the model of public administration practiced elsewhere, especially in the developed world. 相似文献

Over the past seven years, Japan's party system has undergone a transition from single-party rule to multi-party coalitions, albeit under continuing LDP dominance. The LDP's propensity for coalition politics has been influenced not only by the loss of its Diet majorities but by a number of other factors including the end of the polarized party politics of the Cold War period. In this article, Aurelia George Mulgan, Associate Professor of Politics at the University of New South Wales, Australian Defence Force Academy, explains the LDP's complex Diet management strategy underlying its choice of coalition partners. At the same time, Dr. George Mulgan argues that these strategies represent just a more developed form of the deal-making politics the LDP pursued during periods of evenly balanced Diet forces in the 1970s and 1980s. The key difference is the greater level of transparency and Diet-centered nature of inter-party negotiations. 相似文献

In an attempt to learn more about the validity of the Offer Self-Image Questionnaire for Adolescents (OSQ), the 11 scale scores for 14 male and 26 female adolescent patients in a private psychiatric hospital were correlated with their scores on 13 of the 14 minnesota Multiphasic Personality Inventory (MMPI) Scales. Of the 144 correlations calculated, 27% were significant at least at the 0.05 level and 5% were significant at the 0.01 level. The OSQ seems to be measuring depression, anxiety, and self-devaluation as they affect emotional tone, mastery of external problems, psychopathology, and adjustment. Further work needs to be done with normal adolescents concerning the validity of the OSQ scales. Additional research on the Impulse Control and Social Relationship scales is especially needed to determine the exact meaning of these scales. A review of some of the pertinent literature shows that self-report methods are appropriate and efficient in clinical work and research with adolescents. A general comparison of the OSQ and the MMPI shows that the MMPI has the advantage of good validity scales and other statistical properties, while the OSQ appears more attractive because of its appropriateness for adolescents.Received Ph.D. in clinical psychology from the University of Bonn in West Germany. 相似文献

Act of XIX/1998 on Criminal Procedure that had become known in theeyes of the public and the legal sciences as The New Code on CriminalProcedure was promulgated by the Hungarian Parliament on its sessionof 10th of March 1998. The reason for the creation of such an Act was theeagerness to finally get rid of the criminal procedure act of the socialistera, e.g. to get rid of its principle of equality of two main phases: theinvestigation and the procedure in front of the court. Also it was among thepurposes of the new act to adjust our rules of procedure to the regulationsof the Western European Countries. The legislator was took into considerationthe general principles and institutions of Act XXXIII of 1896 on CriminalProcedure, without reviving its surpassed parts. The practices of the Strasbourginstitutes were considered as well. 相似文献

This paper discusses how Marxist understandings of politics and civil society, particularly Marx's own work, can contribute to understanding the dynamics of political change in contemporary capitalist democracies. While briefly exploring the conceptual problems contained in the political-philosophical agenda set out in Marx's earliest works, the paper argues that his subsequent examinations of civil society and class relations are grounded in a political economy of capitalist development which retains considerable salience. The possibilities of a post-Marxist politics of civil society are assessed in this light, using the example of recent neo-liberal and neo-conservative assaults on the welfare state to indicate the ways in which membership of civil society is itself a critical focus of political contestation. A politics of civil society (for example, contemporary 'third way' strategies) lacks any substantive democratic potential, without the type of radical political economy developed by Marx. 相似文献
