Divorce, although a statistical norm, is a developmental trauma to the children involved. This article looks at the two-camp emotional environment of a divorcing family and its effect on the formation of a child's identity. By examining developmental ages, chosen according to divorce research, the author attempts to show how the interspouse emotional cathexes negatively affect a child's sense of self in ways specific to the child's age at the divorce.  相似文献

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

This paper links the policy context regarding S&T parks to the objectives and characteristics of the established parks and incubators in a relatively small, converging European country. S&T parks and incubators in Greece during the past decade and a half have gradually shifted in terms of ownership and management from university/research institute to the private sector and in terms of financing from public to private funds, also involving the provision of seed capital and access to venture capital. This gradual shift toward more private engagement has created a variety of models out of which, it is hoped, successful innovative companies will emerge in larger numbers than in the past.

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
