We use matched employee–employer records from the teacher labor market to explore the effects of late teacher hiring on student achievement. Hiring teachers after the school year starts reduces student achievement by 0.042 SD in mathematics and 0.026 SD in reading. This reflects, in part, a temporary disruption effect in the first year. In mathematics, but not in reading, late‐hired teachers remain persistently less effective, evidence of negative selection in the teacher labor market. Late hiring concentrates in schools that disproportionately serve disadvantaged student populations, contributing to challenges in ensuring an equitable distribution of educational resources for all students. 相似文献

Mass media reports attribute the occurrence of decomposed or mummified corpses in a domestic setting mainly to an increasing social isolation of elderly people. Not much is known about the demographic and medical conditions under which individuals are found months or even years after death in their homes. For this study, autopsy reports of individuals found dead and mummified or decomposed between 1993 and 1997 with those from 1963 to 1967 were retrospectively analyzed. Between 1993 and 1997, a total number of 320 individuals were found decomposed at home compared to 412 such cases between 1963 and 1967. The proportion of individuals older than 64 years was significantly higher during the 1990s study period. Furthermore, the proportion of deaths attributable to natural causes was significantly lower during the 1990s, whereas the rate of suicides was nearly three times higher. 相似文献

Nuclear waste policy in the United States has jailed in large part because of public and state opposition to repository siting. However, that outcome was not inevitable. This paver argues that better policy design and greater attention to the crucial tasks of policy legitimation both by the U.S. Congress and by the Department of Energy might have significantly increased the chances for successful implementation. Even though the program now has a highly uncertain future, suggestions are offered for policy learning and change that may increase the probability of success. 相似文献

Native American youth suffer disproportionately from a range of adverse health conditions. Empowering youth leaders to work on community-based solutions has proved effective in reducing tobacco use and gun violence and is now emerging as a promising approach to improving fitness and health. This article, based on direct observation and interviews with key informants, examines the implementation of a Robert Wood Johnson Foundation-funded project that gave tribal youth councils minigrants to design and run diverse projects that encourage physical activity in their communities. The article highlights the institutional challenges that confront health-promotion strategies for disadvantaged populations. Unless they take proper account of organizational, political, environmental, and cultural forces, funders' interventions have limited chances for success and sustainability. 相似文献

When do political parties push for public investments in education, research, and infrastructure? Existing literature has mainly answered this question by pointing to parties’ state?market ideology. In contrast, this article presents a novel argument highlighting the role of parties’ aspirations to office and their ambitions to maximize votes. It builds on the idea that investments not only constitute redistributive tools for politicians, but also work as public means to foster economic growth in the long run. This unique feature makes investments attractive for parties with high office and vote aspirations, because they anticipate government responsibility in the future and can use investments’ dispersed growth effects to appeal broadly to a large, heterogeneous pool of voters. Support for this claim is found through time-series cross-sectional analyses of party manifestos from 22 Western democracies between 1947 and 2013. Results also indicate that parties’ positions on the second social value dimension matter. 相似文献
