The literature consistently shows an association between pubertal maturation and internalizing problems in girls. The association for boys is less clear. The present study examines genetic and environmental influences on the association between pubertal maturation and internalizing problems for boys and girls in two primarily Caucasian adolescent twin/sibling studies: The Swedish Twin study of CHild and Adolescent Development (706 same-sex twin pairs aged 13-14, M = 13.7 years, 50 % female), and the Nonshared Environment in Adolescent Development sample (US-based, 687 same-sex twin/sibling pairs aged 10-18, M = 13.6 years, 47 % female). For girls, more advanced pubertal maturation was associated modestly with more internalizing problems, and that association was entirely explained by shared environmental influences. For boys, the association between pubertal maturation and internalizing problems was weak and inconsistent. Results for girls were remarkably consistent across samples. Findings suggest that nongenetic mechanisms mediate the association between pubertal maturation and internalizing problems. Findings have implications for intervention such that environmental influences shared by twins/siblings may provide the best targets for intervention strategies designed to minimize the potential negative effects of pubertal maturation on internalizing symptoms in girls. 相似文献

International student enrollment in public service degrees such as Public Administration in the United States has grown rapidly. Harnessing this growth to improve the knowledge and expertise of employees in public service is a vital opportunity. However, our survey of public service schools shows that international students perceive an extensive lack of support with financial and linguistic challenges. Furthermore, schools practice little performance evaluation concerning international student experience. We conclude that schools collect more data on international students and communicate better information about programs to improve services and ensure that students know accurately what to expect from their overseas education. 相似文献

The perpetration of bullying is a significant issue among researchers, policymakers, and the general public. Although researchers have examined the link between bullying and subsequent antisocial behavior, data and methodological limitations have hampered firm conclusions. This study uses longitudinal data from 411 males in the Cambridge Study in Delinquent Development from ages 8 to 56 in order to examine the relationship between adolescent bullying and distinct late middle adulthood trajectories of offending, in which different groups of males follow different offending pathways. Results show that self-reported bullying predicts only certain adult offending trajectories but that the effect becomes insignificant once controls are introduced for childhood risk factors, although this may be due to the small number of the most chronic offenders. Study implications and directions for future research are noted. 相似文献

Documenting Louisiana Sugar (http://www.sussex.ac.uk/louisianasugar), an on-line database project rolled out in July 2008 and now freely available, provides historians and social scientists with an innovative tool for examining one sector of the plantation economy and agrarian society in the American South. Utilizing exceptionally detailed annual crop returns and additional census records, the project makes available two fully searchable databases that allow users to examine in micro and macro detail the evolution of one of America's definitive plantation crops, namely cane sugar. These are available on the project's website, which also includes census material, illustrations, bibliographies, and essays. What follows is a report describing the evolution and aims of this innovative effort to make primary sources widely available in digitized form on the internet. 相似文献

This article examines the compatibility between performance improvement and compliance‐based accountability in the implementation of a new system of public health performance management in Ontario. Findings from this mixed‐method study show that only minor elements of performance improvement get incorporated into pre‐existing compliance‐based accountability structures, that reinforcement of accountability structures works to the detriment of performance improvement intentions, and that limiting managerial influence in developing performance measures and targets diminish the utility of information for improvement. The study concludes that achieving a better balance requires an alternative to top‐down decision making that goes beyond consultation to include partnership. 相似文献
