The paper compares public policy on vocational training provided by employers in France, West Germany and the UK, and looks particularly at the way in which responsibilities and costs are shared between government and employers. The paper concludes that fundamental divergencies between training cultures and systems in the three countries require different policies and forms of government intervention.  相似文献

The purpose of this study was to determine how three generations view the contribution and needs of grandparents in Japan. A sample consisting of 239 grandparents, 266 parents, and 274 grandchildren from, urban and rural areas completed the Grandparent Strengths and Needs Inventory (Strom & Strom, 1993). Grandparents reported more satisfaction, success, and involvement in teaching than was observed by parents or grandchildren. Grandparents experienced greater difficulty as well as frustration and saw themselves as less informed about their role than was reported by younger people. Significant main effects were generation, grandchild gender, grandchild age, generations living together, frequency of grandchild care by the grandparent, and amount of time the generations spent together. Implications for building curricula and guidelines for program development are identified.  相似文献

This technical note describes the construction and use of a portable silver nitrate test kit designed to be safely usable in the storeroom during collection condition surveys. It provides the surveying conservator with supplementary test data to better predict the level of hazard presented by soluble salts in collections.  相似文献

UK educational administration scholars have undertaken a survey to redefine the field of knowledge in educational management and/or administration. In responding to the resulting corpus of work, I argue that that this is an exercise in ‘turf talk’. I draw on theorizations of the socio-spatialities of fields of knowledge to consider educational management and/or administration and its border scuffles with policy sociology and the exclusion of debates about knowledge and truth claims that characterize the ‘new humanities’. I suggest that the lack of regard accorded the situated empirical and practical knowledges of practitioners, and the invisibility in the analyses of the active role of head teacher professional associations in the current context, places the academy in an adversarial position vis-á-vis practitioners. As government moves to make research ‘more useful’, and positions academics as training providers and management consultants for head teachers, I propose that educational management and/or administration scholars must move over to share ground and dialogue with the emerging head teacher profession.  相似文献

Objective

Children of mothers with mental illness are at risk for multiple untoward outcomes, including child maltreatment and foster care placement. The purpose of this analysis was to determine the association between maternal mental illness and children's long term safety and stability.

Methods

A multi-sector administrative dataset from the Department of Social Services (DSS) and Department of Mental Health (DMH) was analyzed. The sample was 4,895 low income families (mother and child dyads) first reported to child welfare in 1993 or 1994. Families were followed until March of 2009. Dates of new report and foster care placement were obtained from DSS data. ICD-09 or ICD-10 diagnostic codes were obtained from Department of Mental Health data. Schizophrenic disorders, episodic mood disorders, anxiety disorders and personality disorders were examined.

Results

New reports were more likely for children of mothers with mental illness, regardless of diagnosis. While overall 67% of children had a new report over the course of their childhood, rates ranged from 80 to 90% for children of mothers with mental illness and occurred within a shorter time frame than for other children. In the multivariate models, mood (HR = 1.41, p < .001) and anxiety disorders (HR = 1.32, p < .05) placed children at greater risk for new reports. The proportion of children with foster placements was more than double for children of mothers with mental illness than for other children. In the multivariate model, anxiety disorders were strongly associated with the risk of placement (HR = 1.75, p < .001).

Conclusions and Practice implications

Important differences in safety and stability were found between children of mothers with and without mental illnesses, as well as some variability across diagnoses. Since these mothers had already received services our findings suggest that access is not enough. The services they are receiving or have received may be an ineffective approach to helping them parent safely.  相似文献

In response to the call of BIO2010 for integrating quantitative skills into undergraduate biology education, 30 Howard Hughes Medical Institute (HHMI) Program Directors at the 2006 HHMI Program Directors Meeting established a consortium to investigate, implement, develop, and disseminate best practices resulting from the integration of math and biology. With the assistance of an HHMI-funded mini-grant, led by Karl Joplin of East Tennessee State University, and support in institutional HHMI grants at Emory and University of Delaware, these institutions held a series of summer institutes and workshops to document progress toward and address the challenges of implementing a more quantitative approach to undergraduate biology education. This report summarizes the results of the four summer institutes (2007–2010). The group developed four draft white papers, a wiki site, and a listserv. One major outcome of these meetings is this issue of CBE—Life Sciences Education, which resulted from proposals at our 2008 meeting and a January 2009 planning session. Many of the papers in this issue emerged from or were influenced by these meetings.  相似文献

OBJECTIVE: This study uses administrative data to track the first re-reports of maltreatment in a low-income, urban child welfare population (n=4957) while controlling for other public service involvement. Service system involvement is explored across the following sectors: Child Welfare, Income Maintenance, Special Education, Juvenile Court, and various forms of Medicaid-reimbursed medical or mental health care. This study builds knowledge by adding the services dimension to an ecological framework for analyses and by following recurrence for a longer period of time than prior investigations (7.5 years). METHOD: We model the re-reporting of a child for maltreatment as a function of child, caregiver, service, and neighborhood characteristics using data from birth records, child welfare, income maintenance, Medicaid, adult corrections, juvenile court, special education, law enforcement, and census sources. Bivariate and multivariate analyses are presented, the latter using Cox regression with a robust sandwich covariance matrix estimate to account for the intracluster dependence within tracts. RESULTS: Key results across bivariate and multivariate analyses included a lower rate of re-reporting among children with parents who were high school graduates and/or permanently exited from the first spell on AFDC (p<.0001); and for children in families that received less intensive in-home services compared to those not receiving services, receiving intensive in-home, or foster care services (p<.0001). Higher rates of re-reporting were found for children with Medicaid mental health/substance abuse treatment records (p<.0001) and special education eligibility for emotional disturbance (p<.005). CONCLUSIONS: Caretaker characteristics and non-child welfare service use patterns had a strong association with the likelihood of a child being re-reported to the child welfare agency and should be more heavily attended to by child welfare workers. High rates of service sector overlap suggest that interagency ties and cooperation should be strengthened. The lower risk associated with less intensive in-home services compared to un-served cases may indicate under-identification of in-home service eligibility following a first report of maltreatment.  相似文献
