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

Investigative bodies and other observers have attributed much of the blame for the 1985 MOVE catastrophe in Philadelphia to ineffective management by the city's previously successful mayor, W. Wilson Goode. Goode's behavior toward the disruptive extremist group followed two patterns, both paradoxical: protracted delay followed by excessive haste, and arms-length action that contrasted sharply with his usual hands-on management style. Drawing on the theory of decisionmaking developed by Irving Janis and Leon Mann, this paper suggests that both paradoxes resulted from unresolved decisional conflicts that impeded responsible and rational handling of the problem. The case points to the value of devoting more attention to the psychology of decision-making in educating present and future public managers.  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 contributes to the development of theories on European integration by testing and exploring statistical models on the long-term development of legislative activity of the European Commission. Drawing on legal information gained from the European Union’s PreLex database and analyzing it with the help of statistical analyses, we map out growth patterns of EU law between 1976 and 2003. We construct time-series models and models based on non-linear regression. While the performance of models based on the traditional theoretical approaches, intergovernmentalism and neo-functionalism, is rather poor, the analysis suggests that nonlinear dynamic models might be an interesting avenue for future conceptualizations of the EU integration process. This article is based on a paper presented at the ECPR Standing Group on the European Union Second Pan-European Conference on EU Politics, “Implications of a Wider Europe: Politics, Institutions and Diversity”, 24–26 June 2004, Bologna, Italy. We would like to thank the seminar participants for useful comments.  相似文献

Abstract. The paper replies to Bix and Soper ( Bix 2007 ; Soper 2007 ). Bix's paper raises methodological questions, especially whether a form‐theorist merely needs to reflect on form from the arm‐chair so to speak. A variety of methods is called for, including conceptual analysis, study of usage, “education in the obvious,” general reflection on the nature of specific functional legal units, empirical research on their operation and effects, and still more. Further methodological remarks are made in response to Soper's paper. Soper suggests the possibility of substituting “form v. substance” of a unit as the central contrast here rather than form v. complementary material or other components of a unit. Various reasons are given here for not doing this. Among other things, it is also argued here that form does not, contrary to Soper's suggestion, always follow substance.  相似文献
