Community-based policing requires a radically different philosophical and organizational approach from the more traditional approach to policing. Stress may be experienced during organizational change as areas of responsibility and roles are altered. This study had three primary objectives: to identify (1) the areas officers and their immediate supervisors actually consider stressful, (2) the officers' and supervisors' responses to stress, and (3) the influence of their social support systems on these responses. Data were collected from community coordinators, radio response officers, and sergeants of the Charlotte-Mecklenburg Police Department in North Carolina. The officers and sergeants report specific physiological responses, lack of job involvement, and propensity to leave law enforcement; all responses that are considered by the literature to be related to stress. Stressors that are both common in law enforcement in general and stressors unique to a department implementing community policing are found to be significant. Work social support does appear to affect the level of job involvement of the officers. The finding that sergeants do not appear to feel that they have work social support may be working to the detriment of their ability to cope with stress and their willingness to be involved with their job. 相似文献

The authors expand their methodology for quantifying and comparing civil commitment processes by developing new formulas for the determination of the average commitment detention time and cost. They also examine the effects of specific changes in commitment procedures on the average detention time and cost. Using data from Oregon's civil commitment process, the authors present several examples of the practical application of their methodology and conclude with a discussion of its major administrative and research implications. 相似文献
