To understand the roles of the medical director and the chief of staff, it is important to consider the environment in which they operate. If both the environment and the roles are designed for collaboration and cooperation, these physicians can contribute to the success of the institution.  相似文献

This paper describes an intervention designed to address the special needs of youths with histories of maltreatment and exposure to family and community violence. The primary components of the model include an enhanced therapeutic community environment and a psychoeducation program that is aimed at changing non-adaptive cognitive and behavioral patterns which developed as means of coping with traumatic experiences. The implementation of the model and proximal effects on the therapeutic communities and youths are being examined in comparison to standard residential services. Initial perceptions of staff illustrate the challenges in applying an intervention that calls for changing the organizational culture.  相似文献

This article provides a brief overview of CASAWORKS for Families (CWF), an innovative intervention designed to help substance-abusing parenting women on welfare. CWF was developed in response to the passage of welfare reform legislation in 1996. Factors that provided a background and context for the development of CWF are considered. The rationale, key elements, and the conduct of a pilot demonstration of CWF are described. Evaluation findings that serve to guide the next steps to improve the intervention are reviewed. Finally, new welfare policy priorities emerging around the importance of addressing behavioral health problems among welfare recipients are highlighted.  相似文献

This article explores the possibility of randomly assigning groups (or clusters) of individuals to a program or a control group to estimate the impacts of programs designed to affect whole groups. This cluster assignment approach maintains the primary strength of random assignment--the provision of unbiased impact estimates--but has less statistical power than random assignment of individuals, which usually is not possible for programs focused on whole groups. To explore the statistical implications of cluster assignment, the authors (a) outline the issues involved, (b) present an analytic framework for studying these issues, and (c) apply this framework to assess the potential for using the approach to evaluate education programs targeted on whole schools. The findings suggest that cluster assignment of schools holds some promise for estimating the impacts of education programs when it is possible to control for the average performance of past student cohorts or the past performance of individual students.  相似文献

A qualitative study by ChangeMakers Refugee Forum and the National Refugee Network of the experiences of 18 Convention refugees has highlighted that the standards of safety and protection that Aotearoa New Zealand is obliged to extend to Convention refugees are inadequately met; most notably that there is a significant disparity between United Nations High Commissioner for Refugees quota refugees and Convention refugees, despite there being no distinction between the two within the 1951 Refugee Convention. Themes relating to participants' experiences of destitution, discrimination, and the deterioration of their physical and mental health during the process of seeking asylum and protection emerged from the study. Lack of resources, information and insufficient policies amounts to a lack of security and protection for Convention refugees in Aotearoa New Zealand, revealing an environment where funding, collaboration, and political and public goodwill are minimal.  相似文献

Adults rate vocalizing 3-month-old boys as more socially favorable (pleasant, friendly, fun, likeable, cuddly, cute) than girls when they are producing syllabic sounds. Is the preference due to gender bias or to actual sex differences in the acoustical quality of early vocalizations? In Experiment 1, 59 adults rated videotaped segments of 4 vocalizing boys and 4 vocalizing girls who were dressed identically in white gowns, and labelled with a name representing their sex or a name of the opposite sex. Two infants of each sex produced syllabic sounds, and 2 produced vocalic sounds. Adults rated boys producing syllabic sounds more favorably even when the boys were labelled with the names of girls. Therefore, the preference was not due to gender bias. In Experiment 2, 3 groups of adults (N = 50, 49, and 50, respectively) each viewed and rated 1 of 3 different sets of videotaped infants. The videotapes contained segments of 8 infants (4 boys, 4 girls, 2 of each producing syllabic sounds, and 2 producing vocalic sounds); infants appeared dressed in identical white gowns and were identified only by number, not by name or sex. In addition to the social favorability ratings, adults guessed the sex of the infant. Adults rated syllabic boys more favorably even though gender was disguised, and even though their guesses of gender were no better than chance. In Experiment 3, the vocalizations of the infants who were heard in the 3 videotapes were subjected to spectrographic acoustic analysis. The acoustic quality of boys' syllabic sounds differed from that of girls' only on the feature of nasality. As expected, syllabic, as compared with vocalic, sounds of both boys and girls were similarly longer in duration and differed in frequency characteristics, but these differences were related only to sound category and not to sex. The variance in adult social favorability ratings due to sex of infant was explained by the less nasal acoustic quality of the boys' voices. These results have implications for early socialization, because we know that mothers respond more to less nasal vocalizations. These results parallel the less nasal quality of men's voices as compared with women's voices, and suggest continuities from early vocalizations to speech.  相似文献

Abstract

Although vacation from work provides a valuable opportunity for recovery, few studies have met the requirements for assessing its effects. These include taking measurements well ahead of the vacation, during the vacation and at several points in time afterwards. Our study on vacation (after-) effects focused on two related questions: (1) Do health and well-being of working individuals improve during a vacation? and (2) How long does a vacation effect last after resumption of work? In a longitudinal study covering seven weeks, 96 Dutch workers reported their health and well-being levels two weeks before a winter sports vacation, during vacation and one week, two weeks and four weeks after vacation on seven indicators. Participants' health and well-being improved during vacation on five indicators: health status, mood, tension, energy level and satisfaction. However, during the first week of work resumption, health and well-being had generally returned to pre-vacation levels. In conclusion, a winter sports vacation is associated with improvements in self-reported health and well-being among working individuals. However, these effects fade out rapidly after work resumption. We propose a framework for future vacation research and suggest investigating the role of vacation type, duration and means to prolong vacation relief.  相似文献

Information science stands as a bridge between the practitioner facing clients in a day-to-day world and the mountain of relevant and not-so-relevant information that the social sciences have accumulated. This paper reports one school's attempts to encourage effective utilization of scientific knowledge through experimentation with (1) a computer-based retrieval system, (2) a specialized library of information tools that permits precise retrieval of current materials, and (3) an educational program that stresses the importance of having the best available knowledge as a guide to practice, and provides training in obtaining it.  相似文献

Uncertainty appears to jump up after major shocks like the Cuban Missile crisis, the assassination of JFK, the OPEC I oil‐price shock, and the 9/11 terrorist attacks. This paper offers a structural framework to analyze the impact of these uncertainty shocks. I build a model with a time‐varying second moment, which is numerically solved and estimated using firm‐level data. The parameterized model is then used to simulate a macro uncertainty shock, which produces a rapid drop and rebound in aggregate output and employment. This occurs because higher uncertainty causes firms to temporarily pause their investment and hiring. Productivity growth also falls because this pause in activity freezes reallocation across units. In the medium term the increased volatility from the shock induces an overshoot in output, employment, and productivity. Thus, uncertainty shocks generate short sharp recessions and recoveries. This simulated impact of an uncertainty shock is compared to vector autoregression estimations on actual data, showing a good match in both magnitude and timing. The paper also jointly estimates labor and capital adjustment costs (both convex and nonconvex). Ignoring capital adjustment costs is shown to lead to substantial bias, while ignoring labor adjustment costs does not.  相似文献
