The authors investigated the dimensions and mechanisms of belonging relevant to motivation and achievement among high school students representing 4 ethnic groups. Using survey data from 9th to 12th grade students (N = 5,494) attending 7 ethnically-diverse high schools, structural equation modeling was employed to explore, independently for each ethnic group, the relationships between students’ perceptions of their belonging (encompassing relationships with teachers and peers, extracurricular involvement, and perceived ethnic-based discrimination), motivation (efficacy beliefs and valuing school activities), and academic success. All 4 measures of belonging were significant for European-American and Latino students. However, friendship nominations were not significant for all groups, suggesting potential variability in perspectives across ethnic groups. The strength of the structural model postulating belonging as a mediator, including statistically significant indirect paths, supported the hypothesis that the belonging construct accounted for much of the relationship between student motivation and success across groups.Beverly Faircloth is a doctoral candidate of the University of North Carolina at Chapel Hill. Her research interests include the developmental and motivational processes that support adolescent school engagement in ethnically diverse settings.Jill Hamm is an Assistant Professor at the University of North Carolina at Chapel Hill. She received her Ph.D. from the University of Wisconsin-Madison in 1996. Her research interests are adolescents’ peer relations in ethnically diverse schools and classrooms.  相似文献

This research evaluated a dual pathway model for body dissatisfaction among adolescent boys. The study provides empirical support for the importance of distinguishing between weight and muscularity concerns in understanding male body image. A total of 128 boys from grades 8 and 11 completed a self-report questionnaire. Results indicated that weight and muscularity concerns each made unique contributions to body dissatisfaction and were associated with distinct individual and peer context characteristics. Weight concern was associated with elevated BMI and more frequent appearance conversations with friends. Muscularity concern was significantly greater among boys who reported more frequent muscle-building conversations, had lower BMI, and were older. The results support the importance of distinguishing between and assessing both muscularity and weight concerns in the development of body image dissatisfaction among adolescent boys.  相似文献

Biotechnological enhancement of human capabilities reveals a characteristically modern stance toward nature: Human nature, as given, is an impediment to be overcome on the way to full human freedom. As a form of metaphysical partisanship, the biotech enterprise seems to further the political intention of Thomas Hobbes to nullify human diversity. Commerce in biotech enhancements, and the individual liberty such commerce instantiates, is likely to have the ironic effect of psychic homogenization.

Government borrowing occurs whenever the government forgoes control over some future flow of resources or benefits in order to acquire resources for current use. Based on this definition, the authors identify several ways that state governments borrow, which include widely recognized forms of debt as well as types of actions that are less transparent. Case studies for Connecticut, Illinois, and New York document the large amounts of future commitments that these states have taken on to cover operating deficits over the last decade. The authors conclude by evaluating the usefulness of current financial statements for assessing the amount of borrowing that states have done to support current services and suggest areas for which additional information is needed.  相似文献

Abstract

Despite an overall decrease in residential mobility after the 2007 housing crisis, many households, particularly those that are low income, continue to move in pursuit of a better life. Traditional theories of residential mobility suggest that mobility will occur when housing and transportation costs are cumulatively greater than the cost of moving to a new location. At the same time, the influence of these factors is not likely to be uniform across geographic contexts or for moves up or down the metropolitan hierarchy. Our analysis examines how well affordability measures explain patterns of county-level residential mobility. Specifically, we contrast conventional measures of affordability focused on the ratio of income to housing expense with measures of location affordability that factor in both housing and transportation costs. We find that whereas households tend to move from lower to higher cost locations, transit affordability at the destination plays an important role in mobility decisions.  相似文献
