The goals of this study were to assess the significance of two timing variables (objective timing of menarche and subjective timing, i.e., the belief—not necessarily true—about one's status as early, average, or late maturing) and two cognitive variables (preparation for menstruation and ego functioning) as predictors of the experience of menarche. Subjects were 92 girls who changed from pre- to postmenarcheal between two test occasions, six months apart. Findings were that subjective timing of menarche and preparation were significant predictors of menarcheal experience, while objective timing and ego functioning were not. The results replicated earlier findings based on cross-sectional analyses. Interpretation of the results suggested some directions for further exploration of determinants of initial menstrual experience.This research was supported by National Institute of Child Health and Human Development Grant 16034 to the first two authors.Received Ph.D. from Clark University.

Although scholarship shows how collective memory aids community resilience to hazards, sociopolitical forces erode this transformative potential. A study of Brisbane River floods highlights the entanglement of memory with a myth of flood immunity, created by community faith in dams to prevent flooding, infrequent floods, drought and hydrological misunderstandings, and upheld by floodplain development perceived as an economic booster. When flooding threatened the myth of immunity in 2011, the event was framed as dam mismanagement to deflect attention from poor land use practices and government culpability. This myth endures, leaving South East Queensland no more resilient for unpredictable but certain future flooding.  相似文献

This study explores the role of income for young people with experience in foster care transitioning to adulthood. It draws on in-depth structured interviews with eight staff members and 38 current and former foster youths age 18 years and older, who were participants in an innovative program to build their assets and financial capability. Interviews took place in four sites in three states. This study illuminates how those with experience in foster care seek to obtain and manage money to transition successfully to adult financial roles. Findings suggest that early and practical experiences with money are important for gaining financial capability. The study also highlights the need for child welfare professionals to develop expertise in financial literacy and understand the pitfalls that lie in both traditional and nontraditional financial services. By deepening understanding among staff of the economic realities facing the young people today, child welfare agencies will be more likely to prepare former foster youths for life on their own.  相似文献

Literature on family drug treatment courts (FDTCs) suggests that parental participation in these courts is associated with improved substance abuse treatment and child welfare system outcomes. Despite these beneficial outcomes, FDTCs serve only 7‐10% of eligible child welfare involved families. As part of a FDTC evaluation, this FDTC site sought to provide stakeholders with information about costs and benefits. Considering the program costs alongside the cost avoidance from reduced time in foster care, this analysis determined that FDTC participation resulted in a net savings per child of $9,710. The cost component of the evaluation proved valuable, challenging, and informative.  相似文献

What is a social rule? This paper first notes three important problems for H.L.A. Hart’s famous answer in the Concept of Law. An alternative account that avoids the problems is then sketched. It is less individualistic than Hart’s and related accounts. This alternative account can explain a phenomenon observed but downplayed by Hart: the parties to a social rule feel that they are in some sense ‘bound’ to conform to it.

The leading school reform policy in the United States revolves around strong accountability of schools with consequences for performance. The federal government's involvement through the No Child Left Behind Act of 2001 reinforces the prior movement of many states toward policies based on measured student achievement. Analysis of state achievement growth as measured by the National Assessment of Educational progress shows that accountability systems introduced during the 1990s had a clear positive impact on student achievement. This single policy instrument did not, however, also lead to any narrowing in the Black‐White achievement gap (though it did narrow the Hispanic‐White achievement gap). Moreover, the Black‐White gap appears to have been adversely impacted over the decade by increasing minority concentrations in the schools. An additional issue surrounding stronger accountability has been a concern about unintended outcomes related to such things as higher exclusion rates from testing, increased dropout rates, and the like. Our analysis of special education placement rates, a frequently identified area of concern, does not show any responsiveness to the introduction of accountability systems.© 2005 by the Association for Public Policy Analysis and Management  相似文献
