This paper examines if ‘naming and shaming’ is an effective tool to increase accountability in school dropout for cities with disadvantaged student populations. It argues that a comparison with other cities might be unfair if regional and population characteristics differ. It discusses the example of two Dutch new towns. The new town policy deliberately attracted low- and medium-income households in the past, such that today the population of those cities differs from other cities. We use a matching analysis to account for observed differences in population and regional characteristics. The results point out that ‘naming and shaming’ may be a dangerous policy to increase accountability: early school leaving differences are driven, to a large extent, by observed differences in population and regional characteristics. 相似文献

An attributional analysis of neonatal euthanasia was undertaken in two studies to compare the responsibility attributions of nursing and non-nursing students (Study 1) and nurses (Study 2) toward a physician for a critically ill neonate's death. In both studies, vignettes about a newborn's death differed with respect to the physician's treatment of the critically ill newborn. In the student study, the physician was attributed the least responsibility for the newborn's death when cardiopulmonary resuscitation was attempted but failed, followed by the physician's issuance of either a "Do Not Resuscitate" order or an order to turn off the infant's respirator. Greatest responsibility was attributed to the physician when he ordered the infant's nutritional and hydration support to be terminated. In addition, the student's major (nursing vs. non-nursing) and the nursing student's educational cohort impacted the level of physician responsibility attributed. In contrast, the nurses' study found that the termination of nutritional and hydrational support was viewed as different from the physician's other three actions. 相似文献

Conflicting legal, administrative, and professional policies surround family involvement in the deinstitutionalization process. This article addresses these discrepancies and makes recommendations for developing effective and consistent channels of policy among social workers and other helping professionals. 相似文献

We describe the summative assessment of role-play scenarios that we previously developed to teach central topics in the responsible conduct of research (RCR) to graduate students in science and engineering. Interviews with role-play participants, with participants in a case discussion training session, and with untrained students suggested that role-playing might promote a deeper appreciation of RCR by shifting the focus away from wanting to simply "know the rules." We also present the results of a think-aloud case analysis study and describe the development of a behaviorally-anchored rating scale (BARS) to assess participants' case analysis performance. 相似文献

Between 1990 and 2007, the number of Catholic schools in the United States decreased by 14% and enrollment diminished by 7%. We generate two measures of publicity of sexual abuse at the diocesan level—public disclosure and news coverage. Dioceses with higher rates of negative publicity had a larger decline in both the number of Catholic schools and overall Catholic school enrollment. We estimate that publicity arising from sexual offenders within the Church explains 5% of the decline in the availability of Catholic schooling. (JEL I21, H52, H44) 相似文献

We show that with common knowledge and a common rate of time preference, the potential loser can always avoid wasteful conflict through a time-consistent series of small concessions. We examine how the failure of each of these assumptions may explain why conflicts arise. We also debate which actions may be helpful in such unfortunate circumstances. 相似文献

SmithKline Beecham (SBPI) is a major player in the Indian pharmaceutical industry. Though relatively small in terms of turnover, it has performed Pharmaceuticals (India) exceptionally well in terms ofprofitability and growth rate. The firm has substantial cash reserves. However, the firm operates in 'mass production' mode at present, with the established finished goods inventory norms being in the range of 1 to 1.5 months. Competitive pressure on the firm is now forcing it to move towards world class manufacturing and the application of concepts from MRP II, JIT and OPT is under consideration. This paper describes the considerations that went into the justification, design and implementation of an integrated production planning and control system in this situaion. 相似文献

This research presents the results of two related studies on the convergent and construct validity of three measures of reciprocity in exchange relationships at work. In Study 1, 71 Dutch teachers were interviewed about their specific investments and outcomes in the exchange relationships with their students, colleagues and school. ANOVA revealed that they reported significantly more investments than outcomes, and that the number of reported investments and outcomes mentioned varied as a function of the type of exchange relationship. Building on these results, multi-item scales were created to assess reciprocity at a detailed level for each of the three exchange relationships. Study 2 validated these specific reciprocity measures by relating them to two global assessments of reciprocity (convergent validity) as well as to measures of job stress and well-being (construct validity). LISREL-analysis of data obtained from a further sample of 224 teachers revealed that for each type of exchange relationship there were significant, consistent and meaningful relationships among the three reciprocity measures. Further, hierarchical regression analysis showed that the reciprocity measures were differentially related to job stressors and measures of well-being. Implications are discussed. 相似文献
