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

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.

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
