This article investigates whether and the extent to which “white flight” from Hispanic and Limited English Proficient (LEP)
students has been occurring in California’s public schools and further, examines the level (school or district) on which “white
flight” may operate. Using school-level administrative data from the California Department of Education from 1990 to 2000,
we estimate exponential growth rate models of white enrollment with school-level fixed effects. The results shed light on
the implications of immigration for school segregation in the United States. The analysis indicates that white enrollment
declined in response to increases in the number of Spanish-speaking LEP and Hispanic students, and that “white flight” from
LEP or Hispanic students occurred more at the district than the school level in the case of primary schools, and at the school
level for secondary schools. In addition, schools with higher percentages of Spanish LEP students in the school than the district,
and with higher percentages in the district relative to the county, experienced greater losses in white enrollments than other
schools, thus suggesting that higher levels of segregation in the wider metropolitan area accelerate white flight. 相似文献

The central aims of this paper are: (1) to explore the utility of using personal correspondence as a source of data for sociological investigations into the history of sociology in the UK; (2) in relation to this undertaking, to advance the beginnings of a figurational analysis of epistolary forms; and (3), to provide an empirically-grounded discussion of the historical significance of the Department of Sociology at the University of Leicester (a University largely ignored in 'standard histories' of the subject) at a formative phase in the development of the discipline within the UK. The correspondence drawn upon in the paper is between Norbert Elias and Ilya Neustadt between 1962 and 1964 when Elias was Professor of Sociology at the University of Ghana and Ilya Neustadt was Professor of Sociology and Head of the Sociology Department at the University of Leicester. From an analysis of this correspondence, we elucidate an emergent dynamic to the relationship between Neustadt and Elias, one which, we argue, undergirds the development of sociology at Leicester and the distinctive character of the intellectual climate that prevailed there during the 1960s. The paper concludes with a consideration of whether it was a collapse of this dynamic that led to a total breakdown in the relationship between Neustadt and Elias, and by extension, an important phase in the expansion of sociology at Leicester. 相似文献

Adolescents take more risks in the presence of their peers, but the mechanism through which peer presence affects risky decision‐making is unknown. We propose that the presence of peers increases the salience of the immediate rewards of a risky choice. The current study examined the effect of peer presence on reward sensitivity in a sample of 100 late adolescents ages 18 through 20 (M=18.5) using a delay discounting task, which assesses an individual's preference for immediate versus delayed rewards. Participants were randomly assigned to complete the task alone or with 2 same‐age, same‐sex peers observing. Consistent with our prediction, adolescents demonstrated a greater preference for immediate rewards when with their peers than when alone. Heightened risk taking by adolescents in the company of their friends may be due in part to the effect that being with one's peers has on reward sensitivity. 相似文献

This paper shows that the bootstrap does not consistently estimate the asymptotic distribution of the maximum score estimator. The theory developed also applies to other estimators within a cube‐root convergence class. For some single‐parameter estimators in this class, the results suggest a simple method for inference based upon the bootstrap. 相似文献

Past literature in nonprofit management uses the overhead ratio of nonprofits as a measure of efficiency. Although the overhead ratio might measure top‐heaviness, we argue that it does not measure nonprofit efficiency. To investigate this, we use financial and operational data to rank the efficiency of Habitat for Humanity affiliates with the overhead and administrative ratio, as well as data envelopment analysis (DEA) and stochastic frontier analysis (SFA), two of the most popular efficiency measures. While the DEA and SFA rankings are statistically correlated, overhead ratio rankings are negatively correlated with both SFA and DEA rankings. We argue that nonprofit scholars, managers, and donors should move away from concepts and measures of efficiency based on financial ratios, and toward ones that embrace maximizing what nonprofits are able to make and do. 相似文献

Abstract Social smokers manage the conflicting aspects of their liminal identities by negotiating complex roles of performance and exchange. Using a combination of methods, including both participant observation of cultural performances and informal interviews, to elicit lay theories and accounts of self-conscious practices, this project examines social actors, self-defined as nonsmokers (or reformed smokers), who engage in recreational tobacco use. Through in-depth interviews and observations of self-identified female social smokers, we document general characteristics of this subpopulation, sampled from a large Midwest capital and its surrounding areas. Social smokers occupy an untenable social space; as neither smokers nor nonsmokers, they use both practices and discourses about those practices to stake their claim to an untenable social position. We conclude with a theoretical discussion that compares our findings with other discourses on smoking, especially the discourse of addiction narratives. In an age of increasing awareness of the health consequences, smoking has become a culturally unavailable category producing “disconfirming realities” in which social smokers constantly renegotiate their status. 相似文献

Objective. In September 2005, approximately 150,000 Gulf Coast residents fled to Houston, Texas, seeking shelter following Hurricane Katrina. Since the majority of evacuees were poor African Americans, the political and social consequences of the storm inspired a national dialogue on race and class. However, in Houston, the discourse on Katrina evacuees also involved immigration concerns. The city's distinction as a gateway to new arrivals influenced the dialogue on the evacuees' impact on the local area. This article assesses the extent to which race, class, and immigration concerns influenced Houstonians' beliefs about the Katrina evacuees. Methods. We analyze data from the 2006 and 2008 Houston Area Survey in order to assess attitudes toward these newcomers at two distinct time periods: within six months of their arrival and then again more than two years later. Results. Our findings show that both national and local factors influenced beliefs about the Katrina evacuees. Conclusions. The dynamics of race/ethnicity and apprehension toward immigrants drove largely antagonistic beliefs about the mostly poor, mostly black new arrivals. 相似文献
