The role of subsequent school contexts in the long-term effects of early childhood interventions has received increasing attention, but has been understudied in the literature. Using data from the Chicago School Readiness Project (CSRP), a cluster-randomized controlled trial conducted in Head Start programs, we investigate whether the intervention had differential effects on academic and behavioral outcomes in kindergarten if children attended high- or low-performing schools subsequent to the preschool intervention year. To address the issue of selection bias, we adopt an innovative method, principal score matching, and control for a set of child, mother, and classroom covariates. We find that exposure to the CSRP intervention in the Head Start year had significant effects on academic and behavioral outcomes in kindergarten for children who subsequently attended high-performing schools, but no significant effects on children attending low-performing schools. Policy implications of the findings are discussed. 相似文献

Abstract Objective: This study aimed to understand the gaps in college students' knowledge regarding sexual health information. Participants: A sample of 242 participants enrolled in an introductory college course participated in this study in the Fall 2009 semester. Methods: Students participated in 1 of 2 brief interventions and wrote a response paper about their experience. The papers were analyzed using conventional content analysis for information that was new to participants by looking for key words that suggested learning took place. Results: The findings indicated that the majority of participants learned new information. Most learning occurred regarding sexually transmitted infections (ie, types, symptoms, prevalence, treatment, testing) and correct condom use. There were also demographic differences regarding reported new information. Conclusions: Findings can be used to develop future sex education programs for college students by providing college educators with an understanding of where students lack knowledge of sexual health. 相似文献

Although studies document the health-enhancing effects of social engagement, they reveal little about the underlying mechanisms operating within specific organizational contexts. Limited attention is given to the role of inequality - particularly age and gender - in shaping either the organizations to which we belong or their consequences for our well-being. We address this issue by examining the Red Hat Society, a social organization for middle-aged and older women. Interviews with members (n=52) illustrate how age and gender inequality interact to shape the organization, which can be viewed as a gendered subculture of aging. Drawing on this framework, we discuss four processes through which participation generates benefits for older women involved in age- and gender-segregated organizations: enhancing social networks, countering invisibility, creating positive frames for aging experiences, and promoting youthful identities. 相似文献

This article seeks to explore the extent to which the military rebuilds or reframes masculinities as a means of meeting the aims of the process of militarization. It focuses on the dimensions of military masculinities that can be distinguished as distinctive in practice. Drawing on Etienne Wenger's notion of communities of practice, this research asks how military men orient themselves in their social and material world, considering the role of practice in the development of military masculinities. A total of 71 semi‐structured interviews were conducted with 53 male and 18 female personnel of various ranks working in the Army, Navy and Royal Air Force. Six focus groups were also carried out (with a total of 10 male and six female participants). Thematic analyses of the narratives indicated that one outcome of militarization is the construction of military masculinities. The military reframes masculinities as a means of meeting the aims of the process of militarization. Dimensions of military masculinities can be distinguished as attributes and qualities and masculinities that are distinctive to the military are constructed through military practice. A strong sense of belonging to the military community of practice is fundamental to the development of military masculinities. In order to feel that one belongs, the recognition and acceptance of others is needed. Those who share the attributes and comply with the practices peculiar to the military achieve this recognition. 相似文献
