Explaining the Consequences of Imprisonment for Union Formation and Dissolution in Denmark 下载免费PDF全文
Crime and subsequent imprisonment reduces men's chances on the marriage market and increases their divorce risk, but existing research, with a few notable exceptions, is silent about the underlying mechanisms driving these effects. This article studies the effect of home confinement under electronic monitoring as a noncustodial alternative to imprisonment on the risk of relationship dissolution and being single, thereby distinguishing between effects of incarceration and of committing crime. We study a policy that expanded the use of electronic monitoring to address nonrandom selection into electronic monitoring instead of in prison. Results from a sample of 4,522 men show that home confinement under electronic monitoring significantly and persistently lowers the risk both of being single and of becoming single during the first five years following conviction. The results show that one of the tools that could promote decarceration trends also secures better relationship outcomes of convicted men. 相似文献

Experimentalists are increasingly examining heterogeneous treatment effects, in which observed individual-level characteristics are hypothesized to moderate an experimental treatment effect. Such work places researchers at the nexus of experimental and observational approaches. In this paper, we discuss the theoretical and statistical issues that can arise in testing such hypotheses. We note that inclusion of an observed (as opposed to randomly-assigned) moderator introduces the possibility of confounds that are commonplace in observational data analysis but too-easily ignored in experimental data analysis. We simulate several different data generating processes that include heterogeneous treatment effects, and we discuss the implications of various statistical models. We aim to provide researchers who examine heterogeneous treatment effects with background and advice that enable them to identify where common issues may arise and to develop research designs and implement statistical tests that will mitigate them. 相似文献

The structure of foreign policy attitudes in transatlantic perspective: Comparing the United States,United Kingdom,France and Germany 下载免费PDF全文

While public opinion about foreign policy has been studied extensively in the United States, there is less systematic research of foreign policy opinions in other countries. Given that public opinion about international affairs affects who gets elected in democracies and then constrains the foreign policies available to leaders once elected, both comparative politics and international relations scholarship benefit from more systematic investigation of foreign policy attitudes outside the United States. Using new data, this article presents a common set of core constructs structuring both American and European attitudes about foreign policy. Surveys conducted in four countries (the United States, the United Kingdom, France and Germany) provide an expanded set of foreign policy‐related survey items that are analysed using exploratory structural equation modeling (ESEM). Measurement equivalence is specifically tested and a common four‐factor structure that fits the data in all four countries is found. Consequently, valid, direct comparisons of the foreign policy preferences of four world powers are made. In the process, the four‐factor model confirms and expands previous work on the structure of foreign policy attitudes. The article also demonstrates the capability of ESEM in testing the dimensionality and cross‐national equivalence of social science concepts. 相似文献

The politicization of government communications requires intense control. Centralization of government power accompanies advances in information and communications technology, as political elites use branding strategy in an attempt to impose discipline on their messengers and on media coverage. The strategic appeal of public sector branding is that it replaces conflicting messages with penetrating message reinforcement. Among the notable features are central control, a marketing ethos, a master brand, communications cohesiveness, and message simplicity. Together these features work to conflate the party government and the public service, which perpetuates trends of centralization. Using Canada's Conservative government (2006–2015) as a case study, public sector branding explains the hyper control over government communications and demonstrates why these developments can be expected to last, regardless of which party or leader is in control. 相似文献

This article revisits regulatory debates about environmental valuation following the Exxon Valdez oil spill to argue that the spill can be seen as a constitutive moment in the rise of neoliberalism. I show that rationalizing environmental values was not simply about applying market rationality to the natural world, but entailed reexamining the nature of that rationality itself and its relevance to social behavior. I then trace the reverberations of these debates beyond the realm of environmental policy, highlighting an underappreciated legacy of the Valdez: the first credit default swap, executed in response to an unprecedented punitive fine leveled against Exxon. Illuminating the linked histories of environmental valuation, corporate environmentalism, and financialization through that event, I argue that environmental valuation is a political problem through which neoliberal strategies for the governance of life (both human and nonhuman) have been forged. 相似文献

The research reported here is an analysis of the evolution of the relationships that comprise a single public health network, focusing especially on the position of the network administrative organization (Provan and Kenis 2008) in the flow of knowledge among a large number of organizations providing similar services. Our study examines the North American Quitline Consortium (NAQC), a multi-sector network that spans the US and Canada and whose members provide telephone-based tobacco cessation services to anyone interested in quitting smoking. Data were collected using web-based surveys at three different points of time. Implications are discussed for network organizing, for both theory and practice, focusing especially on the importance of the network administrative organization in shaping the evolution of the whole network information flow. 相似文献

The maintenance of welfare state policies requires citizen support for the provision of a social safety net through taxation and redistribution. Research has shown that a diverse political polity presents a risk to the welfare state; however, Canada bucks the trend and does not see citizen support for economic redistribution decline in response to immigration-based population diversity. Using Canada as our case, we argue that scholars of welfare state politics and redistribution should turn their attention to other sources of population heterogeneity in an effort to better understand how different political cleavages affect citizens’ redistributive preferences. We use an online experimental survey to manipulate the in-group identity of 500 Canadians. The survey enables respondents to identify with other in-group identities along regional, linguistic, income-group, and urban/rural characteristics. Our results find that while Canadians do have a strong baseline preference for redistributive behaviour, regional and linguistic cleavages moderate this outcome. 相似文献

Many core graduate-level seminars claim to expose students to their discipline’s “canon.” The contents of this canon, however, can and do differ across departments and instructors. This project employs a survey of core American politics PhD seminar syllabi at highly ranked universities to construct a systematic account of the American politics canon. Our results offer valuable insights into the topics and literature that political scientists consider important and on which future scholars base their work. Our article breaks down the literature into a comprehensive list of topics and subtopics, which allows us to identify both an overall field canon and one for each topic, to assess whether some topics receive more attention than others, and to identify which topics are most clearly defined. We explore the extent to which diverse perspectives and methods are (or are not) taught to young scholars, and, although we identify sets of frequently assigned readings and authors within each topic, we also find considerable variation between seminars. 相似文献
