This study of 230 predominantly poor Hispanic and African American women aged 25 to 61 years living with HIV/AIDS in New York City revealed high levels of both sexual (39%) and physical (44%) trauma before the age of 16. Both types of early trauma were correlated with later trauma, and all forms of trauma were significantly associated with current perceived health. In multivariate analyses controlling for relevant covariates, the Powerful Others and Internal Control subscales of the Multidimensional Health Locus of Control Scales (K. A. Wallston, B. S. Wallston, & R. DeVellis, 1978) acted as independent predictors of perceived health rather than (as hypothesized) mediators of the association between trauma and perceived health. Findings underscore the importance of addressing trauma and perceptions of control over one's physical health in the provision of health services to HIV-positive women. 相似文献

The women's movement is often described as „white middle-class” despite the fact that black women not only are more oppressed than whites, but are more favorable to the goals of the women's movement. Black women, especially those identified with the black rights movement, fear that feminism will split their ranks and divert public attention. Black women's problems also differ from those of whites in other ways, mostly related to the fact that their economic position is much worse than that of either white women or black men. Moreover, blacks hesitate to join organizations they perceive as white dominated. It is argued that both black and women's rights movements need each others' support and that black women cannot achieve equality unless both movements succeed 相似文献

Attachment theory offers a way of thinking about the dyadic relationships within the family system. Family systems theory and therapy can contribute to attachment theory, as dyadic relationships do not exist in isolation but within the context of other relationships. Research at the interface between systemic practice and attachment theory is reviewed with examination of the central role they may play together in the developing understanding of family relationships. 相似文献

Previously we showed that stress and depression could result in a 50% lowering of lymphocytic 5-ectonucleotidase (NT) which could be resolved by a diet high in antioxidants. This study suggested that high levels of free radicals mediated by stress/depression may be involved in lowering NT activities. The aim of the present study was to assess whether oxygen radicals could directly affect NT and whether excess free radicals generated in stress/depression may affect tissue ascorbate stores. Exam-stressed students and depressed patients were compared respectively to these students at low stress and depressed patients on high antioxidant intakes. In this study, NT correlated positively with tissue ascorbate stores. A range of antioxidants were tested as possible inhibitors of oxy radical interaction with NT using nitroblue tetrazolium reduction to for-mazan with superoxide anion. At physiological plasma concentrations, ascorbate inhibited this reduction but dehydroascorbate, tocopherol, retinol, selenium, urate, and reduced glutathione were ineffective. Superoxide anion directly reduced lymphocytic NT activity and this effect was reversed by either 100 molar ascorbate in vitro or a high antioxidant intake in vivo. In conclusion, the low NT activities and ascorbate stores found in stressed/depressed people appear to be mediated by higher levels of free radicals reported in these subjects. These conclusions are consistent with published reports of (1) normal NT levels in melancholic patients on high antioxidant diets; (2) heightened inflammatory reponses during stress/depression; (3) low serum levels of zinc in depressed patients. 相似文献

Hood (1995) reported a vertical invisible displacement task where the goal was to find a ball that was dropped down one of three chimneys connected to three hiding boxes below by opaque tubes. Preschool children exhibited perseverative search at the box directly below the chimney where the ball was dropped even though the tubes were always visible and the children were given numerous trials and feedback. This behavior was interpreted as a naive theory of gravity. The current study set out to test the naive gravity theory hypothesis by reversing the motion of the event on a television. On half of the trials the object appeared to fall up the tube into one of the boxes which were now on the top of the apparatus. There were significantly more errors for ‘down’ trials as compared to ‘up’ trials which supports the hypothesis that children are biased to infer that falling objects travel in a straight line whereas anti-gravity events do not conform to this naive theory. 相似文献
