青少年是一个具有较高智力,较高文化和较强自尊的特殊群体,正处于人格和性格的塑造期,他们大多数对人生、自我和复杂的社会缺乏深刻的认识,再加上其他客观原因的影响,青少年群体或多或少地受到心理问题的困扰,而当前中学心理咨询与辅导在硬件和软件方面存在着诸多不足。学校社会工作尊重每一个学生,注重人的潜能的开发与发展,具有自身一套独特的理论和工作方法,与当前的中学心理咨询与辅导相比,具有无可比拟的优势,所以强调和提出学校社会工作介入青少年心理健康辅导的优势及介入的措施显得尤为必要。 相似文献

Education is one major public service in which quasi‐markets and other choice‐based mechanisms are now established methods of delivery. The types of school people choose, and the extent to which their choices are realized, have a fundamental impact on the outcomes of any mechanism of school choice. In this article, we provide a comparative analysis of the school choice strategies of middle‐class families in London and Paris. We draw on approximately 200 in‐depth interviews carried out across the two cities. This enables us to investigate the extent to which middle‐class school choice strategies transcend the institutional context provided by both the local (state and private) schools market and national education policy in England and France. We discuss these findings in the context of current school choice policy and consider their implications for future policy design. 相似文献

Using judgments obtained in interviews with 33 Massachusetts physicians, the annual statewide volume of expenditures incurred for defensive medical reasons in 1982 was estimated to be $1.0 billion, 12% of all medical care expenditures. Estimates for the nation were $37 billion, 14% of expenditures. Nationally, 180,000 cesarean deliveries were thought to be performed for defensive motives. In their own institutions, respondents judged 43% of all skull x-rays following injury to be medically justified, 30% to be defensive medicine, 16% to be placebos, and 11% to be physician misjudgments. In considering the economic and noneconomic costs of medical malpractice procedures, the dollar costs of insurance were considered most serious, followed closely by defensive medicine, unfairness, and poorer relations with patients. Thirty-two percent of the responsibility for the negative aspects of malpractice processes was assigned to lawyers, 21% to physicians, 18% to legislatures and courts, 16% to patients, and 13% to insurance companies. 相似文献

5he purpose of this study was to determine whether or not suspected variables affected a surgery clerk's chances of being awarded an honor rating. Findings indicated a significant relationship between a student receiving an honor rating and his or her preceptor's predetermined level of student advocacy, the number of completed patient interview and physical examination write-ups, and final examination scores. There was no significant relationship found between honor ratings and the preceptor's status, the sequence in which the student was discussed or the length of time spent discussing the student at the final evaluation meeting, or the number of clinical faculty present at the meeting. These results lend support to the faculty forum evaluation approach, but suggest a need for further scrutiny of some influencing variables to ensure all students are fairly considered and honor ratings judiciously awarded. 相似文献

This study considers the problem of inferring a functional evaluation criterion from existing performance measure policies. The objective is to develop a rational basis by which to adaptively evaluate a current best set of performance measures from alternative sets. The analysis is based on a matrix approach for relating system characteristics to performance measures across a set of activities. A procedure for ranking measure combinations which are candidate implementation alternatives is devised using this matrix representation and cost information. An example illustrating the procedure is presented. 相似文献

This article explores the extent to which a decision maker's probabilities can be measured separately from his/her utilities by observing his/her acceptance of small monetary gambles. Only a partial separation is achieved: the acceptable gambles are partitioned into a set of belief gambles, which reveals probabilities distorted by marginal utilities for money, and a set of preference gambles, which reveals utilities reciprocally distorted by marginal utilities for money. However, the information in these gambles still enables us to solve the decision maker's problem: his/her utility-maximizing decision is the one that avoids arbitrage (i.e., incoherence or Dutch books). 相似文献

Lifestyle Education for Activity Program (LEAP) was a comprehensive, school-based intervention designed to promote physical activity in high school girls. The intervention focused on changes in instructional practices and the school environment to affect personal, social, and environmental factors related to physical activity. Multiple process evaluation tools and an organizational assessment tool were developed to monitor program implementation from a framework called the LEAP essential elements, which characterized complete and acceptable intervention delivery; secular trends were also monitored. Using process data, LEAP intervention schools were categorized into low- and high-implementing groups and compared with control schools on nine essential elements assessed at the organizational level. The Wilcoxon scores test revealed that low- and high-implementing intervention, and control schools differed significantly on two of nine administrator-reported organizational-level components: having a physical activity team and having a faculty-staff health promotion program. A mixed-model analysis of covariance indicated that, compared to control schools, a greater percentage of girls in high-implementing schools reported engaging in vigorous physical activity. Process evaluation can be used to understand the relationship between level of implementation and successful program outcome. 相似文献

The purpose of this paper was to examine if the school-attendance requirement of the Personal Responsibility and Work Opportunity Reconciliation Act (PRWORA) significantly increased attendance among the teenage girls that the policy targeted. This study applied difference-in-difference and difference-in-difference-in-difference methods to 12 years of cross-sectional data from the October Supplement of the Current Population Survey while isolating the effects of PRWORA from the effects of other factors that might have influenced the target population's school attendance. The findings indicated that PRWORA, overall, did not have significant positive impacts on school attendance; rather, the policy was associated with a small but significant reduction in school attendance of U.S.-born disadvantaged teenage girls between 1996 through 1999 and essentially no effects on the target population thereafter. 相似文献

Given large numbers of children attending center-based child care and considerable teacher and child mobility, it is important to study correlates and outcomes of children experiencing a change in their primary teacher/caregiver and/or a change to a different child care center. The present study investigated teacher and center stability in a group of 3238 urban, ethnically diverse, low-income, four-year-olds receiving subsidies to attend center-based child care. Children were individually assessed for cognitive and language development at the beginning and end of the pre-kindergarten year. Parents and teachers rated children on their socio-emotional skills and behavior at both time points. Children who experienced a change in their primary caregiver from the beginning to the end of the school year (41% of the sample) showed less growth in initiative for learning and attachment/closeness with adults over time, and scored lower on most indices of school readiness compared to those that had a stable caregiver. Children who moved to a different center during the year scored lower on teacher-reported initiative and attachment. African American children who switched centers were particularly at-risk for poorer outcomes, and boys who experienced a change in primary teacher, in particular, showed slower growth in cognitive development. 相似文献
