Cases of completed suicide among U.S. Navy enlisted personnel occurring from 1974 through 1985 were identified and compared with similar rates in the U.S. general population and in the U.S. Army. Although the Navy suicide rate was the lowest of the three groups, this rate increased between 1976 and 1983. This was in contrast to national and Army trends during the same period. Young white males in the apprentice/recruit and blue-collar occupations had the highest rates of completed suicide in the Navy. Recommendations for prevention and treatment are discussed.  相似文献

This preliminary study examined the effects of a hostility-reduction intervention on patients with coronary heart disease (CHD). Twenty-two high-hostile CHD men were matched on age and hostility and then randomly assigned to a hostility intervention (N = 10) or an information-control group (N = 12). Patients were reassessed immediately and 2 months posttreatment on hostility (with self-report and structured interview) and resting blood pressure. The intervention's overall effect size was moderately strong (d' = .62). Intervention patients reported at both reassessments and were observed at follow-up to be less hostile than controls. At follow-up, intervention patients had significantly lower diastolic blood pressure (DBP) than controls. Finally, reductions in hostility were significantly and positively correlated with reductions in DBP. Replication with a larger sample and CHD outcomes is recommended.  相似文献

This study examined the relationship between physical contact and decision type in predicting “harm to save” behavior. Participants were assigned to making either a judgment or a choice involving moral dilemmas. All participants were presented with dilemmas that either required or did not require having physical contact with potential victims. Participants were asked to decide whether to sacrifice fewer people to save more (utilitarian responses) or not to do so and thus more people would die (deontological responses). The study sample included 345 participants who completed a set of self‐report measures. Results indicated an interaction between physical contact and decision type. In the choice condition only, participants reported significantly less utilitarian responses to the dilemmas that required having physical contact with the person to be harmed than to dilemmas that did not require physical contact. This difference was not found in the judgment condition. These results contribute to a greater understanding of the nature and potential malleability of human morality.  相似文献

Building on the conservation of resources model, we conducted three studies to explore the link between ambient temperature and individual prosocial behavior. In study 1, analyzing the two‐wave field data from a chain of retail stores in Eastern Europe, we find that, in hot, as opposed to normal temperatures, employees are less likely to act in a prosocial manner. In study 2, we replicate and extend these findings in a randomized controlled experiment by identifying mechanisms underlying the relationship between hot ambient temperature and helping behavior. Specifically, we find that heat increases fatigue that leads to reduction in positive affect and subsequently reduces individual helping. Finally, in study 3, we replicate these findings in a field experiment. Taken together, our study helps to explain how and through what mechanisms ambient temperature influences individual helping. The theoretical and practical implications of our findings are discussed.  相似文献

Emotion influences memory in many ways. For example, when a mood-dependent processing shift is operative, happy moods promote global processing and sad moods direct attention to local features of complex visual stimuli. We hypothesized that an emotional context associated with to-be-learned facial stimuli could preferentially promote global or local processing. At learning, faces with neutral expressions were paired with a narrative providing either a happy or a sad context. At test, faces were presented in an upright or inverted orientation, emphasizing configural or analytical processing, respectively. A recognition advantage was found for upright faces learned in happy contexts relative to those in sad contexts, whereas recognition was better for inverted faces learned in sad contexts than for those in happy contexts. We thus infer that a positive emotional context prompted more effective storage of holistic, configural, or global facial information, whereas a negative emotional context prompted relatively more effective storage of local or feature-based facial information  相似文献

This study employs the 1983–1985 data from Social Sciences Citation Index's Journal Citation Reports to examine citation linkages of 10 communication journals. Some newly developed citation indices, together with existing ones, are used to examine the citation characteristics of these journals. The citation patterns found in this study are consistent with Reeves and Borgman's findings. There are some indications of gradual development in the field. However, in comparison with other social science fields, communication is still less developed and occupies only a peripheral position in the ecology of knowledge. The relative lack of interflow within the field and between communication and other fields is quite prominent.  相似文献

We propose a model to measure risk in a prisoner's dilemma based on Coombs' (1973) re‐parameterization of the game as an individual risk decision‐making task that chooses between a gamble of cooperation and another gamble of defection. Specifically, we propose an index, r, to represent the risk associated with cooperation relative to defection. In conjunction with Rapoport's (1967) index of cooperation (K), our formulation of risk allows us to construct games that vary in risk (as indexed by r) while controlling for cooperativeness (as indexed by K). Following utility analysis that models risk seeking as a convex utility function and risk averse as a concave function, we predict that risk‐seeking people cooperate more in games that the cooperation choice is more risky, whereas risk‐averse people cooperate more in games that the cooperation choice is less risky. In the three studies that we varied game parameters, used different measures of risk orientation and prosocial orientation and used different experimental procedures, we found robust results supporting our predictions. Theoretical analysis of our formulation further suggests that risk and cooperativeness of a prisoner's dilemma game is not entirely independent. Games that have a higher cooperativeness index are necessarily more risky. Copyright © 2011 John Wiley & Sons, Ltd.  相似文献

We argue that consumers with high self-brand connections (SBC) respond to negative brand information as they do to personal failure — they experience a threat to their positive self-view. After viewing negative brand information, high (vs. low) SBC consumers reported lower state self-esteem. Consumers with high SBC also maintained favorable brand evaluations despite negative brand information. However, when they completed an unrelated self-affirmation task, they lowered their brand evaluations the same as low SBC consumers. This finding suggests that high SBC consumers' reluctance to lower brand evaluation might be driven by a motivation to protect the self rather than the brand.  相似文献
