Previous research has established the existence of homogeneous religious coping profiles in cardiac-transplantation candidates labeled as the deferring/collaborators, self-directors, and the eclectic religious copers. However, their prospective impact on outcome has not yet been established. This paper examines potential differences between pre-cardiac transplantation religious coping cluster groups on post-cardiac transplantation quality of life (physical functioning, mental health, and general health). Results indicated that the religious coping profiles of deferring/collaborators and self-directors had significantly better scores on mental health and general health than did the eclectics. Implications for religious-coping research and clinical practice are discussed.  相似文献

This study was conducted to examine the relations between dimensions of perfectionism and suicide ideation in an adolescent psychiatric sample. A sample of 66 adolescents from an inpatient psychiatric facility completed the Child and Adolescent Perfectionism Scale, the Child's Hopelessness Scale, and the Suicide Ideation Questionnaire. Overall, the results indicated that socially prescribed perfectionism was associated with greater suicide ideation and that it, along with hopelessness, accounted for unique variance in suicide ideation scores. The findings are discussed in terms of their practical and theoretical significance as well as their consistency with similar research with adults.  相似文献

Managed care organizations can produce conflicts of obligation and conflicts of interest that may lead to problems of conscience for health care professionals. This paper provides a basis for understanding the notions of conscience and conscientious objection and offers a framework for clinicians to stake out positions grounded in personal conscience as a way for them to respond to unacceptable pressures from managers to limit services.  相似文献

CLUSTERS PRECEDE SHAPES IN PERCEPTUAL ORGANIZATION   总被引:2,自引:0,他引:2  
Abstract —Does perceptual grouping require attention? Recent controversy on this question may be caused by a conflation of two aspects of grouping: element clustering (determining which elements belong together) and shape formation (determining cluster boundaries). In Experiment 1, observers enumerated diamonds that were drawn with either lines or dots. These two types of stimuli were subitized (enumerated rapidly and accurately in the range from one to three items) equally well, suggesting that clustering dots into countable entities did not detnand attention. In contrast, when target diamonds were enumerated among distractor squares in Experiment 2. only line-drawn items could be subitized. We propose that clustering and shape formation not only involve different perceptual processes, but play different functional roles in vision.  相似文献

Loomingness and the Fear of AIDS: Perceptions of Motion and Menace   总被引:1,自引:0,他引:1  
The authors examined the role of "perceived loomingness" in fear of HIV. Perceived loomingness refers to perceptions of rapid forward movement and instantaneous changes in the distance and danger of a potential threat (Riskind, 1992). One hundred and twenty undergraduates rated vignettes of two public encounters with an HIV-positive stranger. High-HIV fear subjects perceived greater loomingness and danger in these vignettes than did low-HIV fear subjects. Regression analyses that tested for a mediated model confirmed that the perceptions of loomingness may spark threat cognitions (such as the probability and imminence of harm), which, in turn, lead to fear. As predicted by the harm-looming model, loomingness also had some effects on fear that were not mediated by such standard threat cognitions.  相似文献

Abstract. Theology and ethics intersect with sciences at different points depending upon whether the scholars involved are interested in, for example, general epistemological issues or practical moral judgments. The intersection affects theology and ethics in different ways, depending upon various commitments or resistances on the part of theologians. The author surveys his own writings to show how openness to the sciences has had an impact on various phases of his work and what issues remain somewhat unresolved.  相似文献

Abstract. The development of Ralph Wendell Burhoe's philosophy of religion and science occurred in the shadow of the continuing dialogue about the place of science in American society. Like his friend and mentor, Harvard astronomer Harlow Shapley, Burhoe was distressed and intrigued by the troubled postwar relations between science and religion. Unlike Shapley, however, Burhoe sought to create a new modernism, a blend of religion and science that would allow each to develop and complement the other.  相似文献
