Suicide and rurality in urban society   总被引:3,自引:0,他引:3  
Recent findings suggest that suicide increases with rurality, but research on rural suicide leaves many questions unanswered. This study specifies problems of community organization as a reason for expecting a positive effect of rurality on the suicide rate. A multiple regression analysis of county data shows that rurality has a substantial positive effect and is, in fact, the best predictor of the suicide rate among several variables selected from the previous literature. Additional research is needed to test the interpretation that rurality contributes to an incomplete, fragmented form of community organization which influences the suicide rate by disrupting primary relationships.  相似文献

The authors conducted two full-scale network assemblies for the family network of a suicidal adolescent. Findings from the clinical follow-up and telephone interviews with 21 of 65 participants revealed benefits for the index family and the network members who participated in the meetings. A ripple effect in which the participants' own personal networks improved was also demonstrated. Benefits included resolution of a suicidal crisis, better understanding of depression and family stress, more adaptive responses to depression and suicidal risk, and improved personal relationships. No casualties from this intervention were discovered. This report is intended to stimulate future, more systematic outcome studies.  相似文献

In two experiments, fear was conditioned to the situational cues in one compartment of a hurdle-jumping apparatus and was then extinguished. Subsequently, either one shock (Experiment 1) or three or nine shocks (Experiment 2) were given in a situation distinctively different from that in which conditioning and extinction had taken place. Although some associative strength between the situational cues and fear was shown to have remained after extinction, in neither experiment did the postextinction-shock treatment increase the fear elicited by these cues: Escape-from-fear performance was no better in the shocked groups than in control groups given no additional shock. Thus, the nonassociative hypothesis which postulates that inflating the value of the representation of the UCS with shock-alone presentations can reinstate the extinguished fear of a stimulus was not supported. Rather, the results showed that, after extinction, an increase in fear of a simulus depended on further conditioning to that stimulus. The data also indicated that the nonvisual components of the situational cues predominated over the visual component.  相似文献

The ability to recognize and analyze a personal legend in the conversation of an older person is a useful tool for the skilled, compassionate conversation partner. Having isolated the legend, the empathic listener can offer the teller of the legend the gift of an understanding, clarifying interpretation of its significance.Carolyn K. Dennis, M. Th., is assistant chaplain and program coordinator of the health care lay ministry training program at Gaston Episcopal Hospital, in Dallas, Texas.  相似文献

The intention of this study was to improve behavioral modeling's effectiveness by substituting managers for professional trainers and to evaluate the effect on 44 male supervisors using Kirkpatrick's four levels of evaluation: reaction, learning, behavior on the job, and performance. Twenty-two supervisors were trained with six behavior modeling modules and the effect was compared to a control group consisting of 22 supervisors. The research also examined the effects of trainees’ self-esteem and the perceived power of the trainers. The results showed that behavior modeling resulted in favorable reactions and an increase in learning, but did not produce behavior change on the job, or improved performance results. Power and self-esteem did not moderate the training effectiveness. The findings are compared with previous behavior modeling research. The discussion concludes with a recommendation for researchers to identify more complete theoretical models which explain behavioral change on the job (e.g., Maltz's theory of psycho-cybernetics) as opposed to relying solely on Bandura's social learning theory.  相似文献
