This article describes the current state and range of information protection in the growing number of states and Canadian provinces that employ parenting coordination in an effort to reduce repeat custody litigation. The predominant approach—in which what is revealed during the process is not confidential—is analyzed in terms of its compatibility with the parenting coordinator's multiple tasks of educating parents, seeking to facilitate agreements, and, if necessary, providing the court with a report, a recommended decision, or an arbitrated result. Using a case scenario with multiple parts, the article then examines such confidentiality schemes in practice by providing an action‐oriented series of questions that illustrate how much of this topic must be resolved through a parenting coordinator's exercise of discretion in the absence of rule clarity. The article then raises a number of policy questions about whether current parenting coordination confidentiality norms strike the optimal or even the correct balance on information protection and concludes by identifying several policy options that might address these questions.  相似文献

Recent increases in deaths in the United States from synthetic opioids such as fentanyl and fentanyl analogues (fentanyls) have raised concerns about possible occupational exposures to these potent agents. Medicolegal death investigators and autopsy suite staff might perform job tasks involving exposure to fentanyls. The potential for exposure to fentanyls among medicolegal death investigators and autopsy technicians at a state medical examiner's office was evaluated through review of caseload characteristics, injury and illness logs, and procedures and policies and discussions with management and employee representatives. The evaluation showed that this medical examiner's office had low potential for work-related exposure to fentanyls; its standard operating procedures and personal protective equipment requirements should reduce the potential for occupational exposure. Medicolegal death investigation agencies can develop and implement guidance to control exposures and provide workforce education and training to reduce the potential for work-related exposure to fentanyls.  相似文献

自苏联解体以后,中亚地区成了国际社会瞩目的焦点.作为曾经的苏联国家的一部分,目前该地区充满矛盾.地区内的两个大国--哈萨克斯坦和乌兹别克斯坦选择了不同的发展战略,导致了有趣而充满分歧的结果.取得独立后,哈萨克斯坦选择开放它的经济,而乌兹别克斯坦政府则专注于政治稳定和完全协调发展的经济.1990年代早期,乌兹别克斯坦的策略看上去更合理且更少痛苦,而哈萨克斯坦在那时遭受了严重的经济衰退.然而,到了世纪之交,哈萨克斯坦的经济表现远远超过了它的邻国.本文的目的是分析和比较哈萨克斯坦和乌兹别克斯坦独立早期所选择的两种不同的转型战略,以及评价未来几年里这两种战略的前景和它们所隐含的意义.  相似文献

The present study provides a comparative analysis of sexual-minority and heterosexual emerging adult women’s experiences seeking support for sexual issues from parents and friends. Participants included 229 college women (88 sexual-minority women; 141 heterosexual women), ranging from 18 to 25 years of age, who provided written responses to an inquiry about a time they went to friends and parents for support for a issue related to their sexuality. Responses indicated that the majority of participants had sought support from either a parent or a friend and that mothers and female friends were more likely involved than fathers or male friends, respectively. Sexual issues that participants reported discussing with parents and friends were inductively grouped into five categories: dating and romantic relationships, sexual behavior, sexual health, identity negotiation, and discrimination and violence. Issues that were discussed differed based on sexual orientation identity and the source of support (parent or friend); they did not differ by age. Participants generally perceived parents and friends’ responses as helpful, though sexual-minority participants perceived both parents and friends’ responses as less helpful than did heterosexual participants. Overall, results suggest both similarities and differences between sexual-minority and heterosexual young women’s experiences seeking support for sexual issues from parents and friends.  相似文献

African indigenous vegetables (AIVs) have potential to sustainably address malnutrition, a growing problem in sub-Saharan Africa. Their consumption is however, limited by poor perceptions and lack of awareness of nutritional benefits. There is limited evidence of the effectiveness of community-focused information dissemination approaches in influencing participants’ perceptions and uptake of innovations in AIVs to address malnutrition. This article aims to fill this knowledge gap, using a case study focusing on pastoral communities in Monduli district in northern Tanzania. Target communities participated in a community-based nutritional outreach facilitated by the Good Seed Initiative (GSI), held at Monduli district hospital in September 2014. The results provide evidence of the achievements of the GSI intervention, and the effectiveness of alternative information dissemination approaches.  相似文献

The Russian challenge to the European security system is internal rather than external, because despite all the political efforts at distancing Russia from Europe, the indivisibility remains undiminished. The underlying assumption for Russia’s course is that the West is in irreversible decline, and the conclusion about the dissolution of the West-controlled world order is established in the key doctrinal documents. Instead of passively waiting for this meltdown to develop, it makes perfect sense for the Russian leadership to accelerate it pro-actively, using various levers, including military force. Moscow acts on the assumption that its “unconventional” methods could yield results only if augmented by military threats, against which the Europeans cannot master convincing counter-argument. The imperative to sustain and update credibility of these threats necessitates allocation of greater share of available resources to military build-up, which clashes with economic rationale of reducing this burden in the situation of protracted stagnation.  相似文献

Intelligence products have a degree of uncertainty associated with them. This is typically expressed using linguistic probabilities (e.g., ‘likely’), and some organizations have adopted standardized lexicons for communicating uncertainty. This paper empirically shows that intelligence analysts use a wide heterogeneity of language to communicate uncertainty. This does not include all of the phrases in standardized lexicons used by the intelligence community. In addition, analysts may use some phrases differently to that advocated. Miscommunication of uncertainty can have deleterious effects on decision-making, and so standardization of uncertainty communication should be evidence-based. This paper discusses ways in which such evidence can be generated.  相似文献

Party politics and electoral research generally assume that party members are loyal voters. This article first assesses the empirical basis for this assumption before providing individual‐level explanations for defection. It combines prominent theories from party politics and electoral behaviour research and argues that internal disagreement and external pressure can each bring about disloyal voting. The hypotheses are motivated with multi‐country European survey data and tested on two sets of party‐level national surveys. The results show, first, that, on average, 8 per cent of European party members cast a defecting vote in the last election, and second, that dissatisfaction with the leadership is the strongest predictor of defection. Additionally, internal ideological disagreement is associated with higher probabilities of defection, whereas the effects of pull factors in the form of contentious policies are rather limited. These findings emphasise the importance of testing scientific assumptions and the potential significance of party leadership contests.  相似文献

Human resource management and managerial capacity are well documented in the public management literature as integral management functions. The field has devoted attention to the importance of human resources, but it has yet to consider whether human resource management interacts with capacity in attaining organizational outcomes. Using a large‐N, multiyear data set of public organizations, this article seeks to rectify this gap in the literature. The findings validate scholarly arguments on the importance of public organizations’ need to manage human resources and capacity effectively, identifying just the right combination for performance gains. Empirical results encourage practitioners to consider the ways in which human resource management and capacity work together to influence performance but sometimes undermine each other in counterintuitive ways.  相似文献
