Many factors influence the extent to which nonprofit organizations engage in evaluation. Drawing on organization theory, nonprofit scholarship, and public administration research, we propose a set of hypotheses concerning the interrelationships between organizational characteristics and various aspects of nonprofit evaluation. We test these hypotheses using combined data from an original national survey and IRS Forms 990. Analysis reveals that although higher levels of staff compensation support many aspects of evaluation, higher levels of executive compensation exert negative effects. Additionally, evaluation culture mediates the effects of several variables on evaluation rigor and frequency. Practical implications are discussed for scholars and practitioners. 相似文献

Using a photovoice approach, this study explores stressing factors for African refugees after resettlement in Canada and the strategies they adopt to cope. The study used a purposive sampling procedure to recruit 15 participants (8 women and 7 men). Participants took part in a three-phase process of picture taking, one-on-one interviews, and focus group discussions on the selected pictures. Thematic analysis was applied to analyze the data. Identified stressors included social relationship ruptures, lack of understanding of the new culture, unemployment, and navigating unfamiliar laws and regulations. Coping strategies and recommendations for policies and best practices are discussed. 相似文献

Although it is well established that victimization and delinquency are related, it is not clear how this relationship works, and victims and offenders are still often studied and treated as two distinct groups. General strain theory views victimization as a form of injustice, which can give rise to anger and eventually lead to delinquency. The authors examine victimization, in particular polyvictimization, as a criminogenic factor. Based on a sample of 1,400 youths 12–17 years old in Quebec (Canada), they examine polyvictimization in relation to delinquency as well as negative emotions that can result from victimization namely anger, depression, and posttraumatic stress. The findings show support for general strain theory and highlight the importance of anger for the relationship between victimization and juvenile delinquency. 相似文献

This integrative literature review synthesizes recent empirical knowledge about lesbian and gay immigrants' post-migration experiences. Twenty-four studies with various designs are included. The literature shows that those immigrants encounter some opportunities but also many challenges on economical, social and identity levels, thus soliciting coping strategies. Results are synthesized under five topics: the delicate situation in which they find themselves for revealing their lesbian or gay sexual orientation; the racist and homophobic discrimination they can experience; their renegotiation of socioeconomic status; the identity and affiliation challenges they have to overcome; and the hardships that can impact their health. 相似文献

核不扩散机制使得世界从1945年以后没有发生过核战争,而且帮助防止了核武器扩散至更多国家或流入恐怖组织手中。然而,当前围绕禁止核武器条约的态势,可能会分散国际社会对核不扩散机制的关注和努力,这是禁止核武器条约的反对者和怀疑者们所担心的。禁止核武器条约的讨论得到国际支持,主要是因为核武器国家未能在《不扩散核武器条约》框架下就核裁军显示出“诚意”。无核武器国家占据大多数,而其中的多数又不能接受核裁军没有进展的现状,也不愿意成为有核国家启动核战争决策的人质。此外,尽管促成禁核条约的种种关切合情合理,但令人担忧的是条约过于简单,从而缺少严格的核查以及强制遵约条款。因此,核武器国家可以单独或与其他核武器国家一道更加认真地履行核裁军义务,设计核裁军机制的范本需要解决禁核条约绕开的关键问题,并需要进行国际辩论,讨论何种条件下首先使用核武器是必要与正当的,才是消除禁核条约造成对立的出路所在。 相似文献

We offer a model of media as a multisided platform, providing entertainment and news to viewers, commercial opportunities to advertisers, and political influence to politicians, thanks to the presence of influenceable voters among the media audience. We characterize a political economic equilibrium, determining simultaneously media choices and politicians’ electoral positions. We show that as the value of political influence increases, the media transitions from catering to commercial advertisers to selling political influence, resulting in policy choices that hurt influenceable voters. 相似文献

The paper builds upon an original pre- and post-election survey that we conducted before and after the 2015 Canadian election. Directly after Election Day, we asked Canadians for which party they voted, and whether they regret their choice. We find that 39% of them are not perfectly happy with their decision, and 4% even say that they made a bad decision. We show that the propensity to regret can be explained by a mixed-utility theory, whereby voters attempt to maximize a mixture of instrumental and expressive utilities. Our study contributes to the literatures on voting behaviour and political economy, which usually considers that voters are either instrumental or expressive, but not both at the same time. 相似文献

AbstractThe question posed in this article is how to explain that the governance of secrecy in EU external relations varies. While the Common Foreign and Security Policy appears to retain its secretive character, the EU’s external trade policy has recently seen a shift towards more transparency. This article argues that to understand this variation, one has to take into account the institutional power of the European Parliament as well as the extent to which the rules and practices of secrecy are perceived as legitimate. The empowerment of the Parliament in trade means that it has had recent success in pushing back secrecy in this area. However, a general finding is that the majority of parliamentarians seem only rarely to question the executive’s governance of secrecy in external relations. The analysis shows that perceptions of legitimacy are crucial to account for different secrecy regimes – a finding that is likely to be relevant for the understanding of secrecy in foreign policy beyond the EU. 相似文献
