Patterns and predictors of center-based early care and education (ECE) of children in foster care were examined. Participants included 192 pre-Kindergarten age children in foster care. Foster parents reported demographics, ECE and other service use. Foster care history data was abstracted from case files. High rates of attendance in ECE prior to Kindergarten, including Head Start, other center-based ECE, or both were found. Children who attended Head Start were younger when first placed in foster care. Children who attended other center-based ECE services were more likely to live with kinship foster parents and foster families with higher incomes. Latent class analysis of ECE quantity, quality, type, and duration revealed three patterns: part-time Head Start, part-time other ECE, and full-time mixed ECE. Child and foster family characteristics predicted these patterns, illustrating distinct groups with potential implications for the development of children in foster care.  相似文献

Objective

We examined whether psychotropic medication (PTM) use was related to testing positive for Chlamydia and Gonorrhea among detained adolescents.

Methods

A convenience sample of 550 detained adolescents ages 14-18 years were recruited from eight youth detention centers in Georgia. Using A-CASI technology, data was collected on demographic factors, use of PTM, and sexual risk behaviors. Chlamydia and Gonorrhea diagnoses were assessed by laboratory testing.

Results

Thirteen percent (13.1%) of adolescents not using PTMs tested positive for STIs compared to only 4.9% of those reporting PTM use. PTM users had a 62% smaller odds ratio for testing positive for Chlamydia or Gonorrhea.

Conclusion

Findings suggest that use of psychotropic medication, if deemed useful by detained youth, may be a protective factor against engaging in behaviors which may culminate in contracting some STDs. The practice implications are discussed within the context of these findings.  相似文献

Although many economic analyses of adolescents have examined the costs of risky behaviors, few have investigated the gains that young people derive from such actions, particularly in terms of social payoffs for complying with peer behavior. This paper studies the relationship between adolescents' use of alcohol (relative to that of their peers) and popularity at school. We use data from the National Longitudinal Study of Adolescent Health, a rich and nationally representative survey with detailed information on social networks. Our findings suggest that adolescents are socially rewarded for conforming to their peers' alcohol use and penalized (to a lesser degree) for increasing their consumption above that of their peers. Male adolescents are rewarded for keeping up with their peers' drinking and for getting drunk. Female adolescents are rewarded for drinking per se, but not necessarily for keeping up with their peers. The results offer new information on peer influence and have implications for substance abuse interventions at school and in the community.  相似文献

There is continued interest in employment and subjective well-being among the elderly because of the increasing proportion of elderly population in the labor force. This study investigates the association between part-time and full-time employment and life satisfaction of the elderly in Taiwan. We also examine how these associations may differ across socio-demographic groups. An ordinal treatment effect model is developed to accommodate the discrete feature of the employment decision and the potential endogeneity of these two outcomes. Using a unique sample of the elderly in Taiwan, in contrast to findings for the general population of the previous studies, we find that part-time employment is significant and positively associated with life satisfaction, while elderly with full-time employment have lower life satisfaction. These results are robust across socio-demographic groups.  相似文献

The incorporation of compulsory courses on human rights into the secondary school curriculum in 1998 has been an important first step in developing respect for human rights and responsibilities among the younger generation in Turkey. Yet, these courses have many shortcomings in terms of materials, pedagogy and teacher attitudes. This paper explores Grades 7 and 8 (ages 13 and 14) students’ experiences in Citizenship and Human Rights Education courses on the basis of qualitative data collected through focus group discussions in Ankara and Istanbul in the 2006–2007 academic year. The responses of the students indicate that these courses have had little impact in empowering students or in facilitating them to consider their own or others’ human rights as an integral part of their lives. Rather, the students perceive the national and the global arena as characterized by mass human rights violations against which they feel powerless. The paper draws attention to the importance of a revised human rights education for students along with a global focus and appropriate methodology.  相似文献

Given the varied nature of resource dependent communities, the gendered experiences of women and men may vary in unexpected and contradictory ways. Building on a review and critique of existing theoretical approaches and studies of US and Canadian extractive resource communities in both the feminist and rural social science literature, we provide an analytical approach to engage with gender in the context of these dramatic changes. Our framework, which integrates key insights from recent feminist theorizing, summarizes emergent constructions of masculinity and femininity in a given context by emphasizing the possible contradictions along three broad lines: material, material-discursive, and discursive.  相似文献
