Since its very inception, the United Nations has worked with NGOs (non-governmental organizations) or, to use the contemporary term, a "civil society." In fact, every single U.N. department now has an NGO liaison. As the world becomes increasingly smaller, the role and influence of NGOs will continue to be significant in international negotiations.  相似文献

Since forensic facial approximations are used to promote recognition of a deceased person, an accurate forensic facial approximation (FFA) should be easily recognized as the person to whom the skull belonged (target individual). However, the accuracy of FFAs has been previously assessed by the direct comparison of an FFA to the corresponding target individual for similarity (i.e., a resemblance rating). Resemblance ratings may not indicate a facial approximation's accuracy since the resemblance of non-target individuals is not accounted for. This experiment tests the validity of using resemblance ratings to assess the accuracy of FFAs. The study indicates that there is no statistically significant difference between: (a) resemblance ratings of FFAs to target individuals and (b) resemblance ratings of FFAs to individuals incorrectly identified as the target individual. It is concluded that it is not possible from resemblance ratings to determine the accuracy and/or quality of a facial approximation since a non-target individual may receive a resemblance rating equal to, or higher than, the target individual.  相似文献

Organized medicine has battled the Federal Trade Commission (FTC) since the 1970s over enforcement of the antitrust laws. Physicians' discontent stems from the belief that federal policy allows managed care organizations to achieve dominance in health care markets just as it discourages physicians from taking collective action to protect their interests. This article examines two important efforts by organized medicine over a twenty-year interval to alter federal antitrust policy. In 1982, physicians and other professionals sought a special exemption from FTC jurisdiction; beginning in 1998, physicians promoted legislation that would exempt independent practitioners from the antitrust laws for collective bargaining purposes. Both initiatives passed in the House of Representatives but failed in the Senate. This article uses an advocacy coalition framework to reinterpret the events and to assess the reasons for legislative failure. The evidence suggests that in both instances, although twenty years apart, consumer groups and federal bureaucrats determined the outcome in favor of corporate medicine.  相似文献

Non-missile penetrating brain injuries are rare events in western countries. We report a case with lethal stab injury of the brain and identification of the weapon used in the assault by digital superimposition on CT scans taken at admission of the victim to a hospital. Furthermore, all cases with knife stab wounds of the skull between 1971 and 2000 were analyzed and compared with literature reports. Results of this study show that there is no region preference despite of differences in bone thickness, that stab wounds of the brain are almost invariably associated with multiple stab wounds to the trunk and that the wound tract may correspond to the dimensions of the blade allowing the identification of the weapon by digital image analysis.  相似文献

This note critically interrogates the Civil Partnership Act 2004. Through an examination of the legislative background and some of the provisions of the Act, it is argued that civil partnership mirrors a marriage model with some exceptions. In creating this new legal status, the legislation also exacerbates the exclusion of some relationship forms from dominant legal norms. It should be understood as part of an agenda for social inclusion, rather than as radical social change.  相似文献

Existential anxiety is hypothesized to be a core human issue in a great deal of theoretical and philosophical writing. However, little is known about the emergence of these concerns and their relation to emotional functioning in youth. The purpose of this study was to examine the phenomenon of existential anxiety in a sample of adolescents. Data on existential concerns, identity development and psychological symptoms were collected on a sample of 139 youth in grades 9–12. Results indicated that existential anxiety concerns have a theoretically consistent factor structure, are common among adolescents, and are associated with psychological symptoms, as well as identity issues. Results are discussed with regard to the importance of existential concerns in the lives of youth and the need for additional research.Received PhD from Florida International University. Interests are identity development including associated anxiety and distress, cross-national comparisons, and the development of identity interventions.Received PhD from Florida International University. Interests focus on the developmental psychopathology of anxiety and depression.Received PhD from the University of Arizona. Interests include a range of topics in developmental psychopathology, prevention, program evaluation, and research methodology.  相似文献

Scholars and practitioners within the U.S. education system have focused considerable attention on developing new programs aimed at raising educational achievement for disadvantaged students. New programs are only one way to improve student performance, however; recent work in public administration suggests that public management and implementation practices might also have a large impact on student performance. Existing research shows that managerial networking, managerial quality, and effective personnel management can significantly improve the quality of the education received by disadvantaged students. Additional work highlights the contribution of representative bureaucracy. Because these research agendas have targeted the public administration literature rather than the education policy literature, this article seeks to bring this research back to education policy. Using data from several hundred Texas public school districts, spanning 1995 to 2002, and focusing on disadvantaged student performance (Latinos, blacks, and low‐income students), this article illustrates how both management and processes to enhance the representativeness of teaching faculty produce benefits for disadvantaged students.  相似文献
