Youth who participate in service activities differ from those who do not on a number of key demographic characteristics like socio-economic status and other indicators of risk; and most studies demonstrating positive outcomes among service participants employ small non-representative samples. Thus, there is little evidence as to whether the outcomes associated with service participation are similar among students with varying levels of risk. The National Household Education Survey of 1999, a large nationally representative cross-sectional data set that focused on community service, was analyzed to investigate associations between the risk status of 4,306 adolescent students (50.2% female; 63.3% European American, M age?=?15.9), their participation in community service, and their academic adjustment, behavioral problems, and civic knowledge. Because adolescents who participate in service differ from those who do not with respect to demographic characteristics, propensity score analyses were used to correct for potential selection bias in the examination of these relationships. Analyses tested competing theoretical models of service??protective versus compensatory??among students at varying levels of risk, and suggested that service acts as a compensatory factor with respect to academic, behavioral, and civic outcomes. Propensity score analyses revealed patterns suggesting that, in some cases, students with certain demographic profiles that are themselves related to the likelihood of service participation may benefit from service participation more than others. Findings are discussed in terms of their significance for adolescent development, for planning service programs, and for educational policy. 相似文献

ABSTRACTThis article is situated within nascent debates on the role of academics within food sovereignty movements. Drawing on insights from a collective autoethnography, we report on our experiences conducting three food sovereignty research projects in different contexts and at different scales. We suggest that that the principles and practices of food sovereignty translate into a food sovereignty research praxis. This consists of three pillars focusing on people (humanizing research relationships), power (equalizing power relations) and change (pursuing transformative orientations). This article discusses these pillars and analyzes the extent to which we were able to embody them within our projects. 相似文献

The hundredth anniversary of the original publication of Eugen Ehrlich's Fundamental Principles of the Sociology of Law is nearly upon us. The book earned high praise from Oliver Wendell Holmes, Roscoe Pound, and Karl Llewellyn as one of the outstanding works of its time. Ehrlich has been identified as an early legal realist, a pioneering figure in legal sociology, and a leading theorist of legal pluralism. In this retrospective review, I explain the strengths and weaknesses of this classic book. Ehrlich articulated an unsurpassed account of dynamic social‐legal change, an account that remains fresh and timely today. 相似文献

In this paper, we consider several features of teacher‐retention policies based on value‐added measures of effectiveness under a variety of empirically grounded rules and parameters. We consider the effects of policy design by varying the standard above which satisfactory teachers are expected to perform. We simulate recently adopted policies that remove teachers based on consecutive unsatisfactory performance and compare these to policies that remove teachers based on poor performance on average over a multiyear period. We also consider the precision of the performance measure and the underlying variation in teacher quality on policy effects. Finally, the simulation makes a step forward by incorporating recent empirical findings of a relationship between teacher quality and natural attrition from the profession. Our results indicate that deselection policies based on value‐added measures have the potential to improve teacher quality, although understanding the role of policy design, self‐selected exits, and the underlying variation in teacher quality is essential for determining policy effects. 相似文献

This paper uses an augmented Solow model, with cross section data, to measure the effect on per-capita income of a) the entrenchment of various rights in a country's constitution and b) the level of economic freedom in a country, broadly construed. The results suggest that entrenchment,per se, of any single right seldom has a significant general economic effect, while the effect of economic freedom is significant and substantial. The paper then considers whether such evidence could support the proposition that “constitutions do not matter.” While it concludes otherwise, it does caution against incurring excessive negotiation costs to obtain entrenchment of a comprehensive “wish list” of rights. 相似文献
