Supervisees in Commission on Accreditation for Marriage and Family Therapy Education-(COAMFTE) accredited and candidacy training programs were asked to describe their best and worst supervision experiences in terms of the context of training and supervision, the perceived personal attributes of the supervisor, and specific behaviors perceived to be enacted by the supervisor during supervision. Contextual factors such as supervision modality, frequency and duration of supervisory contacts, and sources of supervisory data appeared to distinguish between supervisees' perceptions of their best and worst experiences. These experiences were further distinguished by the supervisees' perceptions regarding the supervisor's level of interpersonal attractiveness, trustworthiness, and expertise. Key behaviors perceived to be enacted by supervisors during best and worst experiences clustered into several dimensions that included creating an open supervisory environment, communication and encouragement, attending to personal growth, and providing conceptual and technical guidance and direction.  相似文献

OBJECTIVES: Identify associations between lack of formal boater training, drinking and boating, and other unsafe boating practices. METHODS: A telephone survey queried respondents (age 16 or older in continental United States) about boating experience, type of boat used, and training. RESULTS: Of the 3,042 boaters surveyed (70% response), most had no formal training (73%). Boaters with formal training failed to use PFDs about as often as those without formal training and were equally or more likely to use alcohol while boating. CONCLUSIONS: The unexpected association between formal training and unsafe boating practices is probably due to reduced risk perception and inadequacies of boater training programs. Such programs seldom mention the risks of alcohol use while boating. Decisions to mandate formal training should be informed by these results; if mandated, training should address the risks of alcohol use while boating, and should be renewed frequently enough to offset reductions in risk perception.  相似文献

1. The lack of psychiatric services for the mentally retarded is of particular concern for advanced practice nurses in psychiatry. 2. Prevalence of psychopathology and behavioral problems in the mentally retarded appears to be significant. 3. For purposes of diagnostic clarity, a thorough mental status and neurological examination specifically devised for the mentally retarded population must be utilized.  相似文献

conclusion The Information Age has revolutionized the workplace. While it is possible to purchase or copy machines and technology, their very interchangeability means they fail to cre-ate a sustained competitive advantage for an organization (Barney, 1991). The research directions this paper offers are intended to develop firm knowledge that allows creation of inimitable human resources. Importantly, in the rush to embrace new information technologies, organizations must remember the fundamental principle that workers will invest in firm goals in the presence of shared values and a commitment by the firm to make their well-being a priority. We urge continued attention to fulfillment of the psy-chological contract, and to the "people issues" that frequently seem less critical than issues of hardware or technology.  相似文献

Relying on demographic and labour surveys which the Palestinian Central Bureau of Statistics collected in 1995, this article investigates the profile of West Bank and Gaza refugees. Refugees are better educated and have higher fertility than non-refugee Palestinians, but the difference is small. However, they have a significantly lower participation rate, a higher unemployment rate and a higher incidence of arrests and work stoppage than the corresponding rates among non-refugee Palestinians. A smaller proportion of Palestinians commute to work into the Israeli labour market and refugees earn lower wages than non-refugees. Returns to investment in education are small for both groups. High fertility among refugees imposes a future challenge for policy makers in terms of resources required for the provision of appropriate education and health facilities. Employing future labour market entrants is another serious policy challenge.  相似文献

This study used administrative data, census data, and geographic information system (GIS) technology to map and analyze the rates and distribution of child physical abuse, sexual abuse, and neglect at the neighborhood level in a suburban jurisdiction. The results provide an example of how administrative data, census data, and GIS technology can give child protective services and community-based agencies a visual tool to help identify and target neighborhoods in which children may be at high risk for maltreatment.  相似文献

Receiving shadows: governance and liminality in the night-time economy   总被引:1,自引:0,他引:1  
This paper focuses upon the emergence of the night-time economy both materially and culturally as a powerful manifestation of post-industrial society. This emergence features two key processes: firstly a shift in economic development from the industrial to the post-industrial; secondly a significant orientation of urban governance involving a move away from the traditional managerial functions of local service provision, towards an entrepreneurial stance primarily focused on the facilitation of economic growth. Central to this new economic era is the identification and promotion of liminality. The State's apparent inability to control these new leisure zones constitutes the creation of an urban frontier that is governed by commercial imperatives.  相似文献

This paper describes a case study in the application of a productivity analysis model in a plant producing industrial gases. Although the process is a relatively simple one, several inputs (labour, electricity, capital and some materials) and several outputs (liquid and gaseous oxygen, gaseous nitrogen, argon and a hydrogen-nitrogen mixture) are involved. The case study demonstrates how measures of total input and total output can be applied and analyses the performance of the plant over a 15-month period in terms of a variety of managerial control ratios.  相似文献
