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
TIMOTHY B. GRAVELLE JASON REIFLER THOMAS J. SCOTTO 《European Journal of Political Research》2017,56(4):757-776
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

The following is a brief survey of Marx and Engels’ views on ecology, from the viewpoint of their relevance for 21th-century ecosocialism. While there are some serious limitations in the way both consider the “development of productive forces,” there are powerful insights in their discussion of the destructive consequences of capitalist expansion for the environment—an expansion that generates a disastrous metabolic rift in the exchanges between human societies and nature. Some ecological Marxists distinguish between “first stage ecosocialists”—who believe that Marx analyses on ecological issues are too incomplete and dated to be of real relevance today—and “second stage ecosocialists,” who emphasize the contemporary methodological significance of Marx’s ecological critique of capitalism. This paper tries to argue for a third position (which probably could be accepted by several people of the two groups above): Marx and Engels’ discussion on ecological issues is incomplete and dated but despite these shortcomings it does have real relevance and methodological significance today. 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

AbstractThe emerging literature on neoliberal feminism appears to signal the revitalization of the study of feminist ideologies, suspended since the mid-1980s. However, it is argued here that scholars tend to conceptualize neoliberal feminism in a way that inhibits ideological analysis, as exemplified in Nancy Fraser’s Fortunes of Feminism. They take classifications of feminist political ideologies from the 1980s as representative of the only true feminisms, and thus view neoliberal feminism as a perversion, rather than an outgrowth, of earlier feminisms. This account of the emergence of neoliberal feminism is both historically inaccurate and politically problematic: it positions feminists as passive in the face of an overpowering neoliberal agency, and limits feminists’ capacity to imagine themselves as agents of political and ideological change. Building on Michael Freeden’s work on political ideologies, an alternative account of neoliberal feminism is offered, one that locates feminist agency in the production of new feminist ideologies. 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
