Students of American politics rarely study public sector unions and their impacts on government. The literature sees bureaucratic power as rooted in expertise, but largely ignores the fact that bureaucrats often join unions to promote their own interests, and that the power of their unions may affect government and its performance. This article focuses on the public schools, which are among the most numerous government agencies in the country, and investigates whether collective bargaining by teachers—the key bureaucrats—affects the schools' capacity to educate children. Using California data, analysis shows that, in large school districts, restrictive labor contracts have a very negative impact on academic achievement, particularly for minority students. The evidence suggests, then, that public sector unions do indeed have important consequences for American public education. Whether they are consequential in other areas of government remains to be seen, but it is an avenue well worth pursuing.  相似文献

This paper situates food safety concerns raised in the Brexit debate since the referendum and suggests that, although the issue of chlorinated chicken entered public discourse, it represents wider concerns about food safety standards. Food safety has had high resonance in the UK since the 1980s, but Brexit shows how it connects to wider concerns also raised about Brexit, such as impacts on healthcare, the effects of austerity on food poverty, the limitations of low waged employment, concerns about migration and labour markets, and regional economic disparities. Brexit’s impact on the UK food system is immense because food has been highly integrated into EU governance. While food standards can be portrayed as a single narrow issue, the paper suggests it provides a useful lens with which to examine, interrogate and comprehend these wider Brexit politics. The complex realities of food politics and wider food system dynamics undermine any simplistic political narrative of ‘taking back control’.  相似文献

Ola Listhaug Department of Sociology and Political Science, Norwegian University of Science and Technology, N-7491 Trondheim, Norway e-mail: olal{at}svt.ntnu.no e-mail: rabinowitz{at}unc.edu (corresponding author) How should one analyze data when the underlying models beingtested are statistically intractable? In this article, we offera simulation approach that involves creating sets of artificialdata with fully known generating models that can be meaningfullycompared to real data. The strategy depends on constructingsimulations that are well matched to the data against whichthey will be compared. Our particular concern is to considerconcurrently how voters place parties on issue scales and howthey evaluate parties based on issues. We reconsider the Lewisand King (2000) analysis of issue voting in Norway. The simulationfindings resolve the ambiguity that Lewis and King report, asvoters appear to assimilate and contrast party placements andto evaluate parties directionally. The simulations also providea strong caveat against the use of individually perceived partyplacements in analyses of issue voting.  相似文献

Despite the clinical relevance of self-injurious thoughts and behaviors (SITB) among youth, little is known about the subset of youth most at-risk for SITB. This study examined the moderating roles of gender, racial/ethnic background, and school-level (and their interactions) on rates of SITB within a large (N = 2638, 52.2% female), ethnically-diverse sample of middle- and high-school youth in a relatively poor and underserved area of the Southern United States. Extending extant research in this area, findings indicated a significant interaction between gender and race for self-injurious behaviors, with African–American boys reporting higher rates than all other groups. Findings also indicated significant interactions between school-level and both gender and race for self-injurious thoughts. Whereas comparable levels of self-injurious thoughts were reported across middle- and high-schools for girls and African–American youth, the frequency of these thoughts was higher among both boys and White students in high-school (vs. middle-school). Results highlight the need for further research on SITB among diverse youth in underserved areas.  相似文献
