In the context of HIV, women’s sexual rights and sexual autonomy are important but frequently overlooked and violated. Guided by community voices, feminist theories, and qualitative empirical research, we reviewed two decades of global quantitative research on sexuality among women living with HIV. In the 32 studies we found, conducted in 25 countries and composed mostly of cis-gender heterosexual women, sexuality was narrowly constructed as sexual behaviours involving risk (namely, penetration) and physiological dysfunctions relating to HIV illness, with far less attention given to the fullness of sexual lives in context, including more positive and rewarding experiences such as satisfaction and pleasure. Findings suggest that women experience declines in sexual activity, function, satisfaction, and pleasure following HIV diagnosis, at least for some period. The extent of such declines, however, is varied, with numerous contextual forces shaping women’s sexual well-being. Clinical markers of HIV (e.g., viral load, CD4 cell count) poorly predicted sexual outcomes, interrupting widely held assumptions about sexuality for women with HIV. Instead, the effects of HIV-related stigma intersecting with inequities related to trauma, violence, intimate relations, substance use, poverty, aging, and other social and cultural conditions primarily influenced the ways in which women experienced and enacted their sexuality. However, studies framed through a medical lens tended to pathologize outcomes as individual “problems,” whereas others driven by a public health agenda remained primarily preoccupied with protecting the public from HIV. In light of these findings, we present a new feminist approach for research, policy, and practice toward understanding and enhancing women’s sexual lives—one that affirms sexual diversity; engages deeply with society, politics, and history; and is grounded in women’s sexual rights. 相似文献

Although the mapping between form and meaning is often regarded as arbitrary, there are in fact well‐known constraints on words which are the result of functional pressures associated with language use and its acquisition. In particular, languages have been shown to encode meaning distinctions in their sound properties, which may be important for language learning. Here, we investigate the relationship between semantic distance and phonological distance in the large‐scale structure of the lexicon. We show evidence in 100 languages from a diverse array of language families that more semantically similar word pairs are also more phonologically similar. This suggests that there is an important statistical trend for lexicons to have semantically similar words be phonologically similar as well, possibly for functional reasons associated with language learning. 相似文献

Purpose
The purpose of this research is to investigate how organizations can best facilitate an empowered workforce that makes autonomous decisions and acts expediently, which the literature on high performing organizations posits will increase the likelihood of sustained performance and retaining competitive advantages. We introduce a novel mechanism for encouraging such behaviors and pursuant outcomes: vicarious learning from a supervisor who demonstrates autonomy and expediency.Design/Methodology/Approach
We drew experimental data from a sample of participants who underwent a managerial simulation, and used these data to investigate relationships between the vicarious learning of empowered behaviors and individual task performance (n = 100).Findings
Results indicate that when supervisors behave with autonomy and expediency this both increases the extent to which individuals behave similarly, and is associated with enhanced individual performance. Further, we find that expedient behavior fully mediates the relationship between empowered supervisor behavior and performance.Implications
Findings show that supervisors need not necessarily engage directly in empowering others. Rather, by modeling behaviors, supervisors can craft a context where employees may act with autonomy and efficiency. This provides an opportunity for empowerment that is both actionable and cost-effective.Originality/Value
This is the first study to consider empowerment as a managerial phenomenon that can be vicariously learned, integrating theories of social learning and empowerment, and extending existing empowerment constructs (including psychological and structural) to develop an indirect, yet potent means of encouraging empowered behavior.754.
Lewthwaite et al. (2015) reported that the learning benefits of exercising choice (i.e., their self-controlled condition) are not restricted to task-relevant features (e.g., feedback). They found that choosing one’s golf ball color (Exp. 1) or choosing which of two tasks to perform at a later time plus which of two artworks to hang (Exp. 2) resulted in better retention than did being denied these same choices (i.e., yoked condition). The researchers concluded that the learning benefits derived from choice, whether irrelevant or relevant to the to-be-learned task, are predominantly motivational because choice is intrinsically rewarding and satisfies basic psychological needs. However, the absence of a group that made task-relevant choices and the lack of psychological measures significantly weakened their conclusions. Here, we investigated how task-relevant and task-irrelevant choices affect motor-skill learning. Participants practiced a spatiotemporal motor task in either a task-relevant group (choice over feedback schedule), a task-irrelevant group (choice over the color of an arm-wrap plus game selection), or a no-choice group. The results showed significantly greater learning in the task-relevant group than in both the task-irrelevant and no-choice groups, who did not differ significantly. Critically, these learning differences were not attributed to differences in perceptions of competence or autonomy, but instead to superior error-estimation abilities. These results challenge the perspective that motivational influences are the root cause of self-controlled learning advantages. Instead, the findings add to the growing evidence highlighting that the informational value gained from task-relevant choices makes a greater relative contribution to these advantages than motivational influences do. 相似文献

This study uses a cross-sectional research design to examine how individuals perceive recent experiences of identity change in various person, role, and social identities. Specifically addressed is how self-perceptions regarding the magnitude and direction of one’s experience of identity change relate to depression. A survey was administered to 854 study participants that measured perceived changes in 12 discrete identities (four person, four role, and four social identities) over a 6-month period. The results reveal that the more severe one perceives their experience of identity change to be, the greater their level of depression. However, generally, when one perceives that the direction of their identity change is progressive (rather than regressive), they are less likely to be depressed. 相似文献

Expertise facilitates change detection performance, but the neural underpinnings of these benefits are unknown. Expert image
analysts showed larger change-related ERP effects between about 100–200 msec after stimulus onset than did novices, which
correlated with both accuracy and years of analysis experience. These results demonstrate that years of visual experience
can induce fundamental changes in early visual processing which are related to change detection abilities. 相似文献

Action Understanding in the Superior Temporal Sulcus Region 总被引:1,自引:0,他引:1

ABSTRACT— The posterior superior temporal sulcus (STS) region plays an important role in the perception of social acts, although its full role has not been completely clarified. This functional magnetic resonance imaging experiment examined activity in the STS region as participants viewed actions that were congruent or incongruent with intentions established by a previous emotional context. Participants viewed an actress express either a positive or a negative emotion toward one of two objects and then subsequently pick up one of them. If the object that was picked up had received positive regard, or if the object that was not picked up had received negative regard, the action was congruent; otherwise, the action was incongruent. Activity in the right posterior STS region was sensitive to the congruency between the action and the actress's emotional expression (i.e., STS activity was greater on incongruent than on congruent trials). These findings suggest that the posterior STS represents not only biological motion, but also how another person's motion is related to his or her intentions. 相似文献

There has been a recent surge of interest in the question of how infants respond to the social attributes of race and gender information in faces. This work has demonstrated that by 3 months of age, infants will respond preferentially to same‐race faces and faces depicting the gender of the primary caregiver. In the current study, we investigated emergence of the female face preference for same‐ versus other‐race faces to examine whether the determinants of preference for face gender and race are independent or interactive in young infants. In Expt 1, 3‐month‐old Caucasian infants displayed a preference for female over male faces when the faces were Caucasian, but not when the faces were Asian. In Expt 2, new‐born Caucasian infants did not demonstrate a preference for female over male faces for Caucasian faces. The results are discussed in terms of a face prototype that becomes progressively tuned as it is structured by the interaction of the gender and race of faces that are experienced during early development. 相似文献
