The rate of HIV/AIDS among women in India is expected to rise yet few studies have examined factors related to HIV risk among Indian women. The objective of this prospective, cross-sectional study was to characterize similarities and differences in the relationships, psychological well-being, and sexual behaviors among Indian women (N=459). Both HIV positive (N=216) and negative (N=243) women from urban and rural areas in India were included in this study. Chi-square, analysis of variance, and logistic regression analyses revealed that in both geographic groups, HIV-positive women were significantly more likely to report marital dissatisfaction, a history of forced sex, domestic violence, depressive symptoms and husband's extra marital sex when compared to the HIV-negative women. Findings also indicate that specific factors related to the quality of the marital relationship such as domestic violence, martial dysfunction, and depressive symptoms may be related to HIV-related risks for women. Implications for future research and culturally relevant interventions are discussed. 相似文献

In this study, the impact of implicit and explicit activation of gender stereotypes on men's and women's intentions to pursue a traditionally masculine career, such as entrepreneurship, was examined. On the basis of stereotype activation theory, it was hypothesized that men and women would confirm the gender stereotype about entrepreneurship when it was presented implicitly but disconfirm it when it was presented explicitly. Hypotheses were tested by randomly assigning 469 business students to one of 6 experimental conditions and then measuring their entrepreneurial intentions. Results supported the hypothesis when entrepreneurship was associated with stereotypically masculine characteristics but not when it was associated with traditionally feminine characteristics. Men also had higher entrepreneurial intention scores compared with women when no stereotypical information about entrepreneurship was presented, suggesting that underlying societal stereotypes associating entrepreneurship with masculine characteristics may influence people's intentions. However, men and women reported similar intentions when entrepreneurship was presented as gender neutral, suggesting that widely held gender stereotypes can be nullified. Practical implications and directions for future research are discussed. 相似文献

Contrary to the theory and research on employee engagement in the western countries, less consideration has been given to the importance of employee engagement in Asian countries wherein its need is felt more. As more and more companies in Asia realize the importance of a productive workforce, this research examines the mediating role of employee engagement in the relationships of corporate social responsibility (CSR), employee–company identification (E–C) and organizational commitment (OC). Structural analysis of 290 online responses of employees working for various Indian and foreign information technology enabled services (ITES) companies in India, confirms the presence of partial mediation by employee engagement in between its antecedents (CSR and E–C) and its consequence (OC). The proposed model was found to be a good fit. The study provides empirical support to the argument that CSR and E–C are distant antecedents of OC. The results may encourage managers of ITES companies to consider CSR as an investment rather than an expense. 相似文献

N-methyl-D-aspartate (NMDA) receptors play an important role in excitatory neurotransmission and mediate synaptic plasticity associated with learning and memory. NMDA receptors are composed of two NR1 and two NR2 subunits and the identity of the NR2 subunit confers unique electrophysiologic and pharmacologic properties to the receptor. The precise role of NR2C-containing receptors in vivo is poorly understood. We have performed a battery of behavioral tests on NR2C knockout/nβ-galactosidase knock-in mice and found no difference in spontaneous activity, basal anxiety, forced-swim immobility, novel object recognition, pain sensitivity and reference memory in comparison to wildtype counterparts. However, NR2C knockout mice were found to exhibit deficits in fear acquisition and working memory compared to wildtype mice. Deficit in fear acquisition correlated with lack of fear conditioning-induced plasticity at the thalamo-amygdala synapse. These findings suggest a unique role of NR2C-containing receptors in associative and executive learning representing a novel therapeutic target for deficits in cognition. 相似文献

The purpose of this study was to apply a behavioral epidemiology framework reported in J. F. Sallis, N. Owen, and M. J. Fotheringham (2000) to the field of child health psychology and describe the resulting distribution of research phases. Recent volumes of the Journal of Pediatric Psychology were analyzed and their articles classified as belonging to one of five sequentially-ordered phases of behavioral epidemiology research: Phase 1—relationship between behavior and health; Phase 2—measurement and method; Phase 3—factors influencing behavior; Phase 4—intervention; Phase 5—translation. The results indicate that Phase 3 studies (46%) were the most well-represented in the field, followed by Phase 2 (11%), Phase 1 (9%), Phase 4 (8%), and Phase 5 studies (2%). Compared to the journal Health Psychology, the shape of the research phase distribution of articles published in the Journal of Pediatric Psychology was similar. Overall, an encouraging amount of data in the field of child health psychology is being amassed in preparation for behavioral intervention. As research in the field matures, it will likely have a greater impact on public health via chronic disease prevention and control and health promotion interventions. 相似文献

Theoretical and computational analysis of skill learning, repetition priming, and procedural memory 总被引:6,自引:0,他引:6
This article analyzes the relationship between skill learning and repetition priming, 2 implicit memory phenomena. A number of reports have suggested that skill learning and repetition priming can be dissociated from each other and are therefore based on different mechanisms. The authors present a theoretical analysis showing that previous results cannot be regarded as evidence of a processing dissociation between skill learning and repetition priming. The authors also present a single-mechanism computational model that simulates a specific experimental task and exhibits both skill learning and repetition priming, as well as a number of apparent dissociations between these measures. These theoretical and computational analyses provide complementary evidence that skill learning and repetition priming are aspects of a single underlying mechanism that has the characteristics of procedural memory. 相似文献

Cognitive scientists have long used distributional semantic representations of categories. The predominant approach uses distributional representations of category-denoting nouns, such as “city” for the category city. We propose a novel scheme that represents categories as prototypes over representations of names of its members, such as “Barcelona,” “Mumbai,” and “Wuhan” for the category city. This name-based representation empirically outperforms the noun-based representation on two experiments (modeling human judgments of category relatedness and predicting category membership) with particular improvements for ambiguous nouns. We discuss the model complexity of both classes of models and argue that the name-based model has superior explanatory potential with regard to concept acquisition. 相似文献

Texture development during cross rolling of a dual-phase Fe–Cr–Ni alloy: experiments and simulations
Texture development during multi-step cross rolling of a dual-phase Fe–Cr–Ni alloy has been investigated. X-ray diffraction was used to investigate changes in crystallographic texture of both the constituent phases (austenite and ferrite) through changes in orientation distribution function. After deformation, rotated brass (rotated along φ1, i.e. the sample normal direction ND), along with a weak cube texture was observed in austenite, while a strong rotated cube texture was obtained in ferrite. Texture was also simulated for various strains using a co-deformation model by self-consistent visco-plastic (VPSC) formulation. Simulations showed strong rotated brass texture in austenite and a strongly rotated cube, α-fibre (sample rolling direction RD //<1 1 0>) and γ-fibre (ND //<1 1 1>) in ferrite after highest strain (εt = 1.6). VPSC models could not effectively capture the change in crystallographic texture during cross rolling. In ferrite, simulations showed an overestimation of γ-fibre component and an underestimation of rotated cube component. Simulated texture of austenite, on the other hand, showed an overestimation of rotated brass with an absence of cube component. The results are rationalised based on the possible role of shear banding and activation of non-octahedral slip system during cross rolling, both of which are not incorporated in conventional VPSC models. 相似文献
