The present paper uses a rich dataset based on naturally-occurring lotteries for 68 new small non-selective high schools in New York City, which we refer to as small schools of choice (SSCs), to address two related questions: (1) What high school features are promising levers for increasing graduation rates for disadvantaged students? and (2) What high school features helped to produce SSCs’ positive impacts on graduation rates? Our findings provide suggestive evidence that school leadership quality, teacher empowerment, teacher mutual support, teacher evaluation and feedback, teacher professional development, data-driven instruction, teacher/parent communication, academic rigor, personalized learning, and teacher/student respect are promising levers for increasing graduation rates for disadvantaged students. Our findings also provide suggestive evidence that many of these school features explain part of the total average SSC effect on graduation rates, although most of this average effect remains unexplained. Lastly, our findings indicate that SSCs are clearly distinguishable from their counterfactual counterparts in terms of school features that were emphasized by SSC funders.  相似文献

Magocsi has held the Chair of Ukrainian Studies at the University of Toronto for three decades during which he has devoted himself to both Ukrainian and Rusyn history. Critics of Magocsi, particularly in the Ukrainian diaspora in North America, focus on his Rusyn publications while ignoring his great contribution to Ukrainian history which remains unparalleled among other Western historians of Ukraine and other Chairs of Ukrainian History and academic institutions.  相似文献

Political discussion research often focuses on general discussion without analyzing interesting subsets of interpersonal communication, such as political advocacy. Political advocacy is crucial to study because it is where citizens make clear statements of their beliefs when trying to influence others, which democratic theorists cite as valuable in spreading information in discussion networks. In this project, we test theoretically relevant determinants of political advocacy, focusing on campaign spending. Using multilevel logistic regression models of American National Election Study survey data from presidential elections between 1976 and 2008, we find that campaign spending correlates with an increase in the likelihood of advocating. We also find that the likelihood of being an advocate correlates with greater political discussion, television usage, interest in politics, partisanship, efficacy, and socioeconomic status. Additionally, we break these results down by party spending and party identification, and find differentiated results by party. Generally, these results show how the electoral environment shapes interpersonal communication.  相似文献

Abstract

Neighborhoods surrounding large public housing developments have historically been economically distressed. The revitalization of many developments through the federal HOPE VI program, in conjunction with increased inner‐city lending and a strong economy for much of the 1990s, should theoretically lead to improvements in these neighborhoods. This study analyzes changes in selected HOPE VI neighborhoods since 1990 and compares them with changes in other high‐poverty communities, as well as with overall trends in their respective cities.

At the beginning of the decade, conditions in HOPE VI communities were almost universally worse than in other high‐poverty areas. By the end of the decade, the relationship was reversed. The changes resulted from a number of interrelated factors, including the redevelopments themselves, other private market activity, specific commitments of resources by city governments, and increased attention to the communities by lenders. These neighborhoods still qualify as economically distressed, but economic development now seems a realistic possibility.  相似文献

Currently, the use of isotopic ratio as corroborative evidence in criminal trials is explored. Beyond the analytical challenges that have been reported elsewhere, the crucial issue of the interpretation of analytical results in a fair and balanced way remains poorly documented. The aim of this paper is to propose a likelihood ratio approach for the evaluation of stable isotope data acquired from semtex samples. It will also lead to recommendations in relation to the acquisition of normalised international data.  相似文献
