Parental involvement in education is an important determinant of youth’s academic success. Yet, there is limited knowledge on how Latino parents’ education-related involvement changes over time. Using data from a longitudinal study of 674 Mexican-origin families (mother-adolescent dyad; M age of child at Wave 1=10.4, SD?=?0.60), we examined trajectories of parental involvement from 5th to 11th grade and the effects of socio-cultural (e.g., family SES and acculturation) and contextual (e.g., neighborhood) factors on these trajectories. Results showed that mothers reduced two aspects of the educational involvement: home-based involvement and academic aspirations, but increased on a third aspect of involvement, resource seeking. Furthermore, family SES, acculturation, and neighborhood context were differentially associated with mothers’ involvement at 5th grade and predicted changes in involvement across elementary and high school.  相似文献

Abstract

Much has been written and published about the 25 January 2011 Egyptian revolution from the perspective of contemporary history and political science. Much less attention has focused on social policy. I am unaware of any scholarly material that has dealt with illicit drugs during the critical 2011–2016 period, yet increasing drugs consumption provided a social backdrop to the events of that period. This paper identifies historical trends in illicit drugs consumption over the course of the last century to the beginning of the Arab Spring. During much of this period hashish was the drug of choice. This paper argues that drug consumption was on the rise in Egypt well before the downfall of President Husni Mubarak in February 2011, but that it has grown markedly since the ousting of the former president. It will ask which have been and are the drugs of choice in contemporary Egypt. It will further ask how this composition has changed and why, giving special focus to the relatively new mass, opioid drug, Tramadol.  相似文献

Government‐funded training programs in the United States have often been subject to rigorous evaluation. Indeed, many of these programs have been evaluated with random assignment, although sophisticated quasi‐experimental methods have also been used. Until very recently, however, there has been little systematic attempt to use the cumulative information vested in these evaluations to attempt determine which kinds of programs work best in which setting and with respect to which types of client. Meta‐analysis—a set of statistical procedures for systematically synthesizing findings from separate studies—can, in theory at least, address these and other topics that evaluation of individual programs cannot. This article discusses the steps in conducting such a synthesis, summarizes the results of three recently conducted meta‐analyses of training and welfare‐to‐work programs, identifies limitations to the meta‐analytic approach, and considers ways in which some of these limitations can be overcome.  相似文献

Since 1968 more than thirty-five social policy experiments have been conducted in the United States. During this period through 1976 these experiments were generally long-term, large-scale tests of major new programs; thereafter, experiments became markedly more modest in scope. Although hundreds of millions of dollars were spent on the earlier programs, the experiments probably had only a negligible impact on policies. This result stemmed from a variety of factors: Social testing actually tends to exert a conservative influence on policymaking; and the time required to complete experiments and interpret results is often incompatible with the needs of policy makers. In addition, test results are often not effectively communicated to Congress, the administration and the public, and even when the results are conveyed, policy makers are frequently skeptical about the soundness of the methodologies employed. If recent experimental programs are to exert more influence on policymaking, program oficials will need to address these dificulties.  相似文献
