Abuse, health locus of control, and perceived health among HIV-positive women.

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.     

Racism and Feminism: Is Women's Liberation for Whites Only?

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     

Attachment theory and systemic practice: research update

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.     

Evidence for Free Radical-Mediated Reduction of Lymphocytic 5′-Ectonucleotidase During Stress

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.     

Source Monitoring: ERP Evidence for Greater Reactivity to Nontarget Information in Older Adults

Event-Related Potentials (ERPs) were collected concurrently with stimulus presentation during a source monitoring task. Younger adults were less likely than older adults to make source monitoring errors and their ERP records showed far greater discrimination between target stimuli and familiar but nontarget foils. Older adults not only made more source errors but produced high amplitude late positivities to the nontarget foils even when these foils were correctly rejected. Under divided attention conditions, younger adults performance was similar to that of the older adults both behaviorally and electrophysiologically. These data illustrate the role that attentional resources play in the ability to inhibit response tendencies and suggest that age differences in source monitoring may be more related to attentional control than inefficiencies in the encoding of contextual information. As well, they suggest that the ERP late positivity may represent a more general response to item salience rather than serve as an index of recollection as is the current view.
