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

广义上的律师职业拒证特权是律师在诉讼业务和非讼业务中所知悉的公司、个人和非法人团体的秘密拒绝向国家、社会和第三人泄露,狭义上的律师特权是指在刑事诉讼活动中从当事人口述或书面交流中获知的与正在侦查或追诉的案件有关的、不利于当事人的证据信息或信息线索,拒绝向司法机关报告或作证。律师拒证特权使律师处于二难风险:可能受到国家的职业否定,亦可能遭受当事人利益反悔的贬损。律师必须正确、恰当理解职业拒证特权的界限,即不帮助犯罪嫌疑人、被告人隐匿、毁灭、伪造证据或串供,不威胁、诱骗证人作伪证,消极履行真实义务,根据证据,不做违背事实真相的辩护。 相似文献

50余年以来,中国、美国、巴基斯坦三国之间的关系经历了四个演化阶段,但却表现出共同的深层结构,即密切联动、大国主导、小国相机调适。反恐战争后的中巴美三边关系出现了若干新的变化,但由于上述深层结构的决定性作用,可以预见中巴美关系将在历史形成的既有框架中继续演进。 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

This article evaluates the effectiveness of OAS mechanisms for safeguarding democracy through multilateral diplomacy, what some scholars have dubbed the interamerican defense of democracy regime. Drawing on a range of international relations theories, this study derives competing hypotheses about member states' responses to democratic crises in the Americas. It then analyzes all instances in which a collective response—that is, an application of Resolution 1080 or the Inter-American Democratic Charter—was debated in the OAS between 1991 and 2002. Patterns of state behavior suggest that domestic politics, rather than the structural or systemic traits of the interamerican system, best explain foreign policy responses to crises of democracy in the region. The OAS record in confronting such crises is uneven. 相似文献
