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

Abstract: This paper is concerned with an analysis of legislation, public administration and government expenditure decisions on policing activities. These three dimensions of government can be used as mechanisms of social control. Whether they are or not is an empirical question that has to be determined in each case. It is shown that there are no strict relationships between the three dimensions of government activity: separate decision-making is undertaken for each of the three dimensions. It is indicated that there are eight possible combinations of the three dimensions, assuming that the three dimensions of government activity are bivariate and discrete. The empirical analysis relates to the state of Queensland and it is concluded that Queensland can be described as a case consisting of authoritarian legislation, public administration contrary to the rule of law, and low policing expenditures.  相似文献

Lawyers for conservative and libertarian causes are active in organizing and mobilizing interest groups within the conservative coalition, and networks of relationships among those lawyers help to maintain and shape the coalition. Using data gathered in interviews with seventy-two such lawyers, this article analyzes characteristics of the lawyers and the structure of their networks. The findings suggest that the networks are divided into segments or blocks that are identified with particular constituencies, but that a distinct set of actors with extensive relationships serves to bridge the constituencies. Measures of centrality and brokerage confirm the structural importance of these actors in the network, and a search of references in news media confirms their prominence or prestige. This "core" set of actors occupies the "structural hole" in the network that separates the business constituency from religious conservatives. Libertarians, located near the core of the network, also occupy an intermediate position. Regression analysis of ties within the network suggests that the Federalist Society plays an important role in bringing the lawyers together.  相似文献
