奥巴马政府上台后,美国核不扩散政策出现了重要转变。这一转变既是奥巴马政府对布什政府核不扩散政策进行反思的结果,又是修复美国国际形象和维护其世界领导地位的战略需要,更是美国对朝鲜和伊朗的核开发问题施加压力的一种手段。奥巴马政府对美国核不扩散政策的调整,有利于国际核军控工作走上正轨;将对中国产生多重影响;对地区核问题的解决所产生的效果具有不确定性。 相似文献

Desmond Ellis 《Family Court Review》2008,46(3):531-536
Approximately 50% of couples who have separated report being victims of violence and/or emotional abuse by their former intimate partners. Family courts can make an important contribution toward reducing the number of intimate partners who report being victims of domestic violence and abuse during and following their participation in divorce proceedings in three ways. First, increase opportunities for participation in nonadversarial procedures. Second, implement mandatory assessment/screening for domestic violence using field‐tested instruments that link subscores on sets of items (e.g., control motivated violence, conflict instigated violence/abuse, substance abuse associated violence/abuse) with appropriate community‐based treatments and/or resources. Third, educate family court judges, lawyers, mediators, and other court personnel in the dynamics of domestic violence generally, as well as the dynamics associated with separation/divorce. 相似文献

Public-goods dilemmas are characterized by conflicts between self-interest and the welfare of a group or society at large. Research has identified several factors that enhance cooperation in such dilemmas. However, less is known about how concern for distributive justice affects willingness to contribute in asymmetric public-goods dilemmas. To test the hypothesis that contributions to a common resource is related to perceived fairness, experiments were performed to investigate willingness to pay to the social service of child care in hypothetical societies. Experiment 1 aimed at replicating a previous survey study (Biel et al., 1997). Experiments 2 and 3 were extensions. In all three experiments subjects were asked to indicate how fair they considered different distributions of the quality of child care provided by their municipality. These distributions corresponded to the principles of equality, equity, and need. University students (32, 48, and 32 in the three experiments, respectively) served as subjects. Ratings of perceived fairness were positively related to willingness to pay. Other factors also positively related to willingness to pay included ability to pay, personal need, expected payment from others, and the number of households who had to contribute in order to maintain the quality. Furthermore, decreasing municipality size increased willingness to pay. 相似文献

Despite a dramatic reduction in fighting in Burma's ethnic states, militarization has increased as the regime seeks to extend its sovereignty and capitalize on economic opportunities. Rather than ensuring civilians' safety, militarization has exposed more civilians to human security threats, with serious consequences for families and communities. Abuses are likely to continue as long as the regime under-finances its army, disregards disciplinary problems, and receives diplomatic cover from its foreign economic partners. While civilians have sought to manage these threats as best they can, their degree of agency is, in most cases, highly constrained, and women have been particularly affected. Nevertheless, the development of community-based organizations which make use of porous borders to expose abuses and provide assistance to distressed communities constitutes an important, if limited, development. 相似文献

在我国,新世纪以来几件为公众周知的事件促生了一些人所称道的法规和案例。“因事成制”的思维和路径契合我国文化传统,是“因势成事”的具体表现。“因事成制”可以创新制度,也可以进行法律移植。“因事成制”有其存在的现实必要性和可能性,既体现了政治家使新闻传播权利“软着陆”的智慧,又有着深厚的法学理据,论题学法学、伯克利学派,以及哈耶克的有关理论等皆可使其得以证立。“因事”包括“借事”与“造事”,新闻法制变革借事成制已有,而造事未见。 相似文献
