Schools across the country are ending the practice of grouping students based on ability, in part, because of research indicating that tracking hurts low-ability students without helping students of other ability levels. Using a nationally representative survey conducted by the National Center for Education Statistics, (NCES) we reexamine the impact of tracking on high school student achievement through the estimation of a standard education production function. This approach allows us to control for the possibility that track is correlated with factors such as class size and teacher education. In addition, we address the possibility that there are unobserved student or school characteristics that affect both achievement and track placement. Our results indicate that abolishing tracking in America's schools would have a large positive impact on achievement for students currently in the lower tracks, but that this increase in achievement would come at the expense of students in upper-track classes. 相似文献

This article explores the role of Queensland voters in the 2019 Australian federal election. The article identifies five key elements of a Queensland political culture before offering evidence that the Liberal-National Coalition's exceedingly strong performance in Queensland in 2019 was not a single aberration, but one of a long and continuing pattern of electoral nonconformity. The article also argues Queensland's complex regional diversity necessitates analysis across not one or two constituencies but via six geographically, economically and demographically diverse regions. Third, the article argues the unexpectedly large swing against the Australian Labor Party in Queensland in 2019 was fuelled, overwhelmingly, by five factors, each consistent with the five core elements of a Queensland political culture. 相似文献

This article employs the concepts of security culture and normlocalization to explore some of the cultural dimensions of theAfrican Union's (AU) security policies. After providing an overviewof constructivist accounts of norm socialization in internationalrelations, I use these insights to analyse the origins and developmentof the AU's security culture. The final two sections explorethe ongoing process of norm localization in relation to thetwo most recent tenets of the AU's security culture: intoleranceof unconstitutional changes of government and the responsibilityto protect principle. An awareness of the uneven and contestednature of this process helps account for the fact that althoughthese two transnational norms have been institutionalized inthe AU Charter and endorsed by the United Nations, they havebeen internalized unevenly by the AU's member states. Externaladvocates of these two norms would thus do well to help thecontinent's norm entrepreneurs build congruence between thesenorms and the AU's security culture. 相似文献

The Herero were the first ethnic group to be subjected to genocidein the twentieth century. In 2001, the Herero became the firstethnic group to seek reparations for colonial policies thatfit the definition of genocide. The Herero are the latest plaintiffto use the procedures of the Alien Torts Claim Act of 1789 toseek reparations in a US federal court for war crimes committedoverseas. This article analyzes the legal arguments by Hererosagainst Germany within the context of current understandingsof international law and identifies the challenges that lieahead for this claim. The article also explores the implicationsof the Herero claim for other ethnic groups victimized by colonization. 相似文献

Abstract We study the degree of convergence or divergence in fiscal decentralization in the European Union over the period 1995–2015 using a club convergence approach. First, we analyze non-central expenditure and revenue as percentages of GDP, of total expenditure and of total revenue. The results for the EU-15 countries indicate some clustering, with three clubs formed when using GDP and four to five when using total revenue or expenditure. Second, we study the gap between expenditure and revenue as a proxy of fiscal responsibility. This results in three and two clubs respectively, with Denmark as the divergent country with the highest gap. Finally, we analyze potential unions of clubs and transitions. We also interpret our results taking into account variables found in the literature as determinants of fiscal decentralization. These results show how European countries are quite heterogeneous in terms of fiscal federalism and decentralization, with greater convergence in fiscal responsibility than in the other magnitudes. 相似文献

Research on the public affairs profession in both South and Latin America is one of the leading limitations today in international public relations research. This study helps to lessen such a gap by offering more realistic insight into the ideologies and pressures that govern public affairs practice in Chile. In‐depth interviews were conducted with 15 experts who are current senior‐level public affairs practitioners in the Chilean capital of Santiago. Results offer three key insights: First, the core function of public affairs in Chile surrounds behaviors of lobbying and governmental relations. Second, leveraging cohesion between organizational private interest and the public interest is a key to leveraging pressure on elected officials and governmental agencies. Lastly, there is significant concern regarding public trust in the lack of transparency in the Chilean public affairs field, facilitated by insufficient governmental regulation. Such research offers practical and grounded insights for public affairs and public relations scholarship. 相似文献

As the emergence of nongovernmental conservation efforts generates conflict among various stakeholders, the causal story that each party articulates regarding conservation and the causes of land degradation reflects their unique interests. This study uses existing literature to evaluate causal stories surrounding a contemporary conservation effort: Montana's American Prairie Reserve. Through qualitative review of web‐based documents and newspaper articles, it generates a preliminary account of key stakeholders' causal stories. The case study suggests that parties who might be disadvantaged by ascribing responsibility for environmental harms in an adversarial fashion may instead elect to articulate causal stories that are more neutral than existing approaches might forecast. The study concludes by suggesting that further development of causal story literature may enable it to better address contemporary conservation efforts. 相似文献
