A number of case reviews and observations have reported on the effects, on counsellors, of working with victims of violence. In this study two groups of counsellors, sexual assault counsellors (n = 41) and counsellors from a range of other therapy areas (n = 32), were compared on a number of measures including the Maslach Burnout Inventory, Ways of Coping Scale and a Beliefs and Values Questionnaire. The results indicate that sexual assault counsellors experience greater emotional exhaustion and use more escape/avoidance coping strategies. Responses concerning beliefs and values are discussed in terms of McCann and Pearlman's constructivist self-development model and indicate support for the concept of vicarious traumatization. Implications of these findings for Sexual Assault Services are discussed. 相似文献

Assessments of aggregate exposure to pesticides and other surface contamination in residential environments are often driven by assumptions about dermal contacts. Accurately predicting cumulative doses from realistic skin contact scenarios requires characterization of exposure scenarios, skin surface loading and unloading rates, and contaminant movement through the epidermis. In this article we (1) develop and test a finite-difference model of contaminant transport through the epidermis; (2) develop archetypal exposure scenarios based on behavioral data to estimate characteristic loading and unloading rates; and (3) quantify 24-hour accumulation below the epidermis by applying a Monte Carlo simulation of these archetypal exposure scenarios. The numerical model, called Transient Transport through the epiDERMis (TTDERM), allows us to account for variable exposure times and time between exposures, temporal and spatial variations in skin and compound properties, and uncertainty in model parameters. Using TTDERM we investigate the use of a macro-activity parameter (cumulative contact time) for predicting daily (24-hour) integrated uptake of pesticides during complex exposure scenarios. For characteristic child behaviors and hand loading and unloading rates, we find that a power law represents the relationship between cumulative contact time and cumulative mass transport through the skin. With almost no loss of reliability, this simple relationship can be used in place of the more complex micro-activity simulations that require activity data on one- to five-minute intervals. The methods developed in this study can be used to guide dermal exposure model refinements and exposure measurement study design. 相似文献

This paper uses data from an intensive study of Boston's antebellum black community to demonstrate how sustained social activism is embedded in the formal and informal institutions of the community. The social networks of cooperative institutions were primary factors in this community's ability to mobilize and sustain protest actions and to call attention to social injustice. This examination of antebellum black Boston indicates that the issue of slavery was crucial to social activism. This suggests that the presence of a salient issue which links the everyday lives of participants with a public issue may be an important factor in building a social movement based in a poor, relatively powerless community. 相似文献

The purpose of this article is to demonstrate how social network analysis can be used to provide information for policy decisions pertaining to physicians' adoption and utilization of new medical technology. Interviews and hospital records were used to obtain data on refenals, consultations, discussions, and on-call coverage; utilization of a computer-based hospital information system; and personal and practice characteristics from 24 physicians who belong to a private group practice. The results of a block-model analysis suggest that the physician's relative position in the network is an important determinant of his/her participation in the diffusion process. A number of policy implications related to the introduction of new medical technology into practice settings are discussed. 相似文献
