The DNA commission of the International Society of Forensic Genetics (ISFG) was convened at the 21st congress of the International Society for Forensic Genetics held between 13 and 17 September in the Azores, Portugal. The purpose of the group was to agree on guidelines to encourage best practice that can be universally applied to assist with mixture interpretation. In addition the commission was tasked to provide guidance on low copy number (LCN) reporting. Our discussions have highlighted a significant need for continuing education and research into this area. We have attempted to present a consensus from experts but to be practical we do not claim to have conveyed a clear vision in every respect in this difficult subject. For this reason, we propose to allow a period of time for feedback and reflection by the scientific community. Then the DNA commission will meet again to consider further recommendations.  相似文献

This article considers two recent books in the history of childhood, youth, and the law: Holly Brewer, By Birth or Consent and Stephen Robertson, Crimes Against Children . It argues that these works mark the emergence of age as a category of analysis in sociolegal studies. It calls for further investigations in the legal history of childhood and youth, outlines several areas of interest, and suggests that attention to age will alter how scholars look at the law by complicating key concepts such as innocence, authority, and citizenship. Studies of age and the law could benefit from cross-cultural and transnational approaches.  相似文献

COMPSTAT, the latest innovation in American policing, has been widely heralded as a management and technological system whose elements work together to transform police organizations radically. Skeptical observers suggest that COMPSTAT merely reinforces existing structures and practices. However, in trying to assess how much COMPSTAT has altered police organizations, research has failed to provide a broader theoretical basis for explaining how COMPSTAT operates and for understanding the implications of this reform. This article compares two different perspectives on organizations—technical/rational and institutional—to COMPSTAT's adoption and operation in three municipal police departments. Based on fieldwork, our analysis suggests that relative to technical considerations for changing each organization to improve its effectiveness, all three sites adopted COMPSTAT in response to strong institutional pressures to appear progressive and successful. Furthermore, institutional theory better explained the nature of the changes we observed under COMPSTAT than the technical/rational model. The greatest collective emphasis was on those COMPSTAT elements that were most likely to confer legitimacy, and on implementing them in ways that would minimize disruption to existing organizational routines. COMPSTAT was less successful when trying to provide a basis for rigorously assessing organizational performance, and when trying to change those structures and routines widely accepted as being "appropriate." We posit that it will take profound changes in the technical and institutional environments of American police agencies for police departments to restructure in the ways anticipated by a technically efficient COMPSTAT.  相似文献

Serious conflicts can arise when contacts between a child and a parent require supervision unless specific guidelines and objectives are clarified for all involved parties. This article discusses supervision objectives, the importance of maintaining the parent-child relationship, instances warranting recommendation for no parental contact, qualifications of the supervisor, and practical guidelines for supervision.  相似文献

The most ferocious debates are about whether the United States should be described as imperial, but in practice other countries also try to influence other countries’ domestic policies, to propagate their visions, to exert power and to stabilize areas beyond their borders that are perceived as a source of threats. While in the 1990s the winners of globalization were seen as small open states, since the turn of the millennium big powers appear to be gaining because of their ability to project political power: the United States, but also China, Russia, India, and Brazil. This makes for a greater instability and leads to the formulation of theories of realism or neo-realism. The essay concludes with an examination of alternatives to empire and the neo-imperial vision, in particular the importance of elaboration of common or shared values in helping to build a safer and more peaceful international order.  相似文献
