A growing body of research is examining the strengths and weaknesses of specific after school programs and their effect on youth outcomes. Few reviews, however, have sought to examine the components of citywide system-building—to understand intentional efforts to develop, support and sustain high quality after school programming across a community. Beginning in the mid-1990s and continuing through the present, private funders, public officials and program practitioners in cities across America have joined together to build systems to support the expansion and improvement of after school programs at the city-level. This paper presents the community context and underlying principles that drove the development of Baltimore’s After-School Strategy; articulates a set of system components derived from this experience and the available literature; and lays out future work to expand high quality after-school opportunities for youth in Baltimore and in other distressed urban environments.  相似文献

Using a collaborative research approach, this project describes a partnership between community residents and university researchers to develop a comprehensive survey of the after-school needs of a low-income urban community in a large Midwestern city. Surveying parents and children was considered particularly important because the current literature on after-school does not include much input from them, the key stakeholders in programming. By surveying pre- and young adolescent youth (N = 416) and parents (N = 225) in the community, information was gathered to document the need for after-school programming, tap program preferences, and uncover barriers to participation and enrollment. Survey findings revealed significant differences between youth and parent perspectives. Disagreements between youth and parent survey responses suggest that after-school programs in the community should offer a balance of academic, recreational, and social activities, as well as a tutoring or homework component. Further, in order to increase participation and attendance rates, community after-school programs need to address the following barriers to participation: safety, transportation, family responsibilities (e.g., care for siblings, household chores), and access to information about available programs. These findings guided the planning of future after-school programs. The survey results and comparisons between youth and parent data will be presented.  相似文献

A unique observational data set was used to explore quality at the point of service in after-school programs. Staff practices in after-school settings were represented on a series of unidimensional scales closely indexed to staff behavior. In order to account for heterogeneity of staff performances, pattern-centered methods were used to construct profiles of common staff practices. Results revealed six pedagogy profiles that were classified in terms of three broad types of performances delivered by after-school staff: (1) positive youth development, (2) staff-centered, and (3) low-quality. Staff membership in these profiles was not related to youth-staff ratio. However, results revealed significant differences between the profiles on the content of the offering and the age of youth in the setting.  相似文献

In the current study, we examined parent gender differences in feelings (negativity and positivity) and perceptions of child behavioural and emotional problems in adoptive and biological parent-child dyads. In a sample of 85 families, we used a novel within-family adoption design in which one child was adopted and one child was a biological child of the couple, and tested whether the links between parent feelings and child maladjustment included effects of passive gene-environment correlation. Parents reported more negativity and less positivity as well as higher levels of externalizing behaviour for the adopted child compared to the non-adopted child, although effect sizes were small and no longer statistically significant after correcting for multiple comparisons. Fathers and mothers did not differ significantly in their reports of positive and negative feelings towards their children or in regard to child externalizing and internalizing behaviours. The correlations between parental negativity and positivity and child externalizing and internalizing were similar for fathers and mothers, and for adopted and non-adopted children. The findings suggest similar parent-child relationship processes for fathers and mothers, and that genetic transmission of behaviour from parent to child does not account for the association between parental warmth and hostility and child-adjustment problems.  相似文献

Research on youth mentoring highlights the importance of the relationship quality between mentor and mentee; mentoring results in more positive outcomes when the mentee perceives the relationship as satisfying and trustworthy. Research on relationship quality shows that social skills are important for constructing new relationships. However, whereas improved social skills are often one of the main goals of youth mentoring, little is known about the importance of social skills for relationship quality in youth mentoring relations. In this study, we examined whether mentee's pre-intervention social skills were related to mentor–mentee relationship quality as perceived by the mentee, and in turn, if relationship quality was associated with post-intervention social skills. We additionally examined possible gender and age differences in these associations. Data were used from a two-wave study that assessed relationship quality and social skills before and after one semester of mentoring of 390 secondary school students in a school-based mentoring program. Results indicated that relationship quality was positively associated with post-intervention social skills. However, only for young mentees pre-intervention social skills were associated with better relationship quality. Moreover, only for young mentees, relationship quality mediated the association between pre- and post-intervention social skills.  相似文献

采用实验法以90名3~5岁的儿童为被试,探讨其在个体和群体情境中延迟策略的使用状况。研究结果表明:在注意转移策略的使用上,存在着显著的年龄差异;在被动策略的使用上4岁组的幼儿具有显著差异;在个体与群体情境下,除了寻求帮助策略上有显著的差异外,其他延迟策略上均无显著差异;在延迟策略的使用上没有显著的性别差异。  相似文献

This study was based on a questionnaire and included a group of home care workers (HCW) (n = 305) and a reference group of municipal employees (n = 694). The relationship between the work environment and musculoskeletal symptoms was analysed. The HCW were less satisfied with their control over their work and stimulus from their work and had a higher physical work load and prevalence of musculoskeletal symptoms, compared with the reference group. The Rate Ratio (RR) of neck and shoulder symptoms among HCW was 83 and 54 %, respectively, higher among those reporting a "high" psychological work load compared with those reporting a "low" load. The highest RR for a single risk indicator was 2.5, and this concerned low-back symptoms among HCW who often worked with twisted postures. A combination of "poor" psychosocial work environment and "high" physical work load produced the highest RR for work-related neck (RR = 2.57) and shoulder (RR = 2.13) symptoms.  相似文献
