We examine interviews from a qualitative study designed to examine HIV perceptions, risk, and risk management among Puerto Rican women who have sex with women (WSW) and who also have been diagnosed with major depression, bipolar disorder, or schizophrenia. These women's stories challenge both the lesbian and the Latino communities to reexamine how and why they claim individuals as their own and they similarly challenge professional communities, including HIV educators, health researchers, and medical care providers, to develop effective HIV prevention programs and counseling approaches that facilitate patient/client self-disclosure and consider cultural and contextual barriers to both self-disclosure and the provision of services. 相似文献

Effective measurement of information system (IS) success continues to be a top concern for both practitioners and researchers. Labeled the “productivity paradox”, previous attempts to quantify the benefits of IS have often resulted in inconclusive or inconsistent results. The present study contributes to IS success research through the development and empirical testing of a process-oriented model of IS success. Using an operational perspective and combining primary and secondary measures, this study examines the influence of lower-level intangible IS and information technology (IT) benefits on higher-level financial measures. Additionally, we introduce IS plan quality as an antecedent to the model's input variables. Primary survey data from CIOs of primarily Fortune 2000 size firms are combined with secondary data, total operational cost, from Compustat to facilitate the examination of the IS benefits. This study also addresses shortcomings cited in other studies that might have contributed to the productivity paradox by including control variables in the model, defining a research perspective—the operational success perspective—and clearly articulating the level of analysis as the organizational level. The results supported a process-oriented view of the benefits from IS and showed how the effects of IS along a path can lead to better organizational performance, in this case, lower overall costs. These results are discussed and future research implications are presented. 相似文献

Observers watched videotaped face‐to‐face mother–infant and stranger–infant interactions of 12 infants at 2, 4, or 6 months of age. Half of the observers saw each mother paired with her own infant and another infant of the same age (mother tapes) and half saw each infant paired with his or her mother and with a stranger (infant tapes). Observers were asked to judge which was the mother–infant dyad in each pair. Observers' accuracy improved as infants aged and was above chance for both mother and infant tapes when infants were 6 months. Differences between mother–infant and stranger–infant dyadic communication patterns also emerged as the infants aged. At 6 months, mother–infant dyads had more symmetrical communication and less asymmetrical communication than stranger–infant dyads. 相似文献
