Examined as an isolated situation, and through the lens of a rare and feared disease, Mr. Duncan's case seems ripe for second-guessing the physicians and nurses who cared for him. But viewed from the perspective of what we know about errors and team communication, his case is all too common. Nearly 440,000 patient deaths in the U.S. each year may be attributable to medical errors. Breakdowns in communication among health care teams contribute in the majority of these errors. The culture of health care does not seem to foster functional, effective communication between and among professionals. Why? And more importantly, why do we not do something about it?  相似文献

In the present work, we examined associations between oppressive, sexist beliefs and consideration of cosmetic surgery for oneself and also endorsement of cosmetic surgery for one's romantic partner. A total of 554 German‐speaking volunteers from the community, mainly in Austria, completed measures of consideration of cosmetic surgery and three measures of sexist attitudes, while a subset of participants in romantic relationships completed a measure of endorsement of cosmetic surgery for their partners along with the measures of sexism. Preliminary analyses showed that women and single respondents were more likely to consider having cosmetic surgery than men and committed respondents, respectively. Further analyses showed that consideration of cosmetic surgery for oneself was significantly associated with sexist attitudes, particularly hostile attitudes to women. In addition, among participants in a relationship, sexist attitudes were associated with endorsement of cosmetic surgery for one's partner. These results indicate that attitudes to cosmetic surgery for oneself and one's partner are shaped by gender‐ideological belief systems in patriarchal societies. Possible implications for understanding the motivations for having cosmetic surgery, among both single respondents and couples, are discussed.  相似文献

Most people living with HIV/AIDS (PLWHA) take steps to protect their sexual partners. However, a minority of PLWHA continue to engage in sexual risk behaviors that might contribute to the transmission of HIV. Psychiatric conditions, including certain pathological traits, are associated with sexual risk behaviors. Research examining the association between narcissistic traits as they relate to HIV transmission risk is limited. In the present study, 303 PLWHA were recruited from an infectious disease clinic and completed questionnaires assessing narcissistic characteristics, substance use, sexual risk behavior, and intentions to use condoms in the future. Narcissistic traits predicted unprotected sex with partners who are HIV-negative or whose HIV status was unknown as well as lower intentions to use condoms, after controlling for demographic factors and substance use. Interventions focused on reducing the transmission of HIV should take into account associations between sexual risk behavior and narcissism.  相似文献

Following the revival of virtue theory, some moral theorists have argued that virtue ethics can provide the basis for a radical politics. Such a politics essentially departs from the liberal model of the moral agent as an autonomous reason‐giver. It instead privileges an understanding of the agent as conditioned by her community, and in the case of social oppression and marginalization, communal virtues may become a vehicle for social change. This essay compares political appropriations of virtue theory by Christian theologian Stanley Hauerwas and secular feminist thinkers Lisa Tessman and Margaret Urban Walker. Hauerwas and feminist theorists both embrace a kind of embodied vulnerability as a political virtue, arguing that it enables more genuine social recognition. The virtue feminist critique is more robust than Hauerwas's, however, insofar as it understands mutual recognition to involve acknowledgment of social difference and the concomitant pursuit of justice.  相似文献

High-hope and low-hope research participants (males and females), as preselected on the basis of a dispositional self-report scale, choose freely between brief audiotaped messages that varied in depressive content. In the first experiment, the messages were of either positive or negative content. Highhope as compared to low-hope persons preferred listening to the positive tapes (no differences related to Gender), and this Hope main effect remained after the shared variance related to depression and positive and negative affectivity were removed. In a modified replication, the contents of the tapes were comprised of successful or unsuccessful goal-attainment statements related to hopeful thinking. High-hope as compared to low-hope persons again preferred to listen to the successful goal pursuit messages (no differences related to Gender), and this Hope main effect on listening choices remained after the shared variances related to depression, positive and negative affectivity, and self-esteem were removed. Implications are discussed.  相似文献

Weighting the arms during locomotion results in decreased swing motion and increased shoulder muscle activity. To determine the functional relevance of this activity, participants walked on a treadmill with the arms unweighted, or weighted unilaterally or bilaterally. Similar to past work, the weighted arms decreased in swing amplitude and increased their shoulder muscle activity. A close examination of shoulder muscle activities in specific regions of the arm swing cycle suggested these muscles primarily acted eccentrically for all weighting conditions. These findings suggest that the increased shoulder muscle activities when weighting the arms act to dampen the arms when the inertial characteristics of the arms are altered, as opposed to assisting in driving swing of the heavier arms.  相似文献

This fMRI study investigated the neural correlates of reward-related trial-and-error learning in association with changing degrees of stimulus-outcome predictabilities. We found that decreasing predictability was associated with increasing activation in a frontoparietal network. Only maximum predictability was associated with signal decreases across the learning process. The receipt of monetary reward revealed activation in the striatum and associated frontoparietal regions. Present data indicate that during reward-related learning, high uncertainty forces areas relevant for cognitive control to remain activated. In contrast, learning on the basis of predictable stimulus-outcome associations enables the brain to reduce resources in association with the processes of prediction.  相似文献
