The credibility of digital identity information on the social web: a user study

A theory of the dynamical conductance of mesoscopic conductors is presented. It is applied to mesoscopic capacitors, resonant double barriers, ballistic wires, metallic diffusive wires, and to the Corbino disk and the Hall bar in quantizing magnetic fields. Central to this approach is a discussion of the charge and potential distribution in mesoscopic conductors. It is necessary to take into account the implications of the long-range Coulomb interaction in order to obtain a charge and current conserving theory. We emphasize the low-frequency response. This has the advantage that the approach is of considerable generality. The theory can be used to discuss the self-consistency of the dc-conductance formula. The theory can also be applied to discuss the rectifying (nonlinear) behavior of mesoscopic conductors.Comment: 29 pages, figures not included (preprints with figures can be obtained by conventional mail on request from T.Christen [email protected]

Exploring Coping and Social Support with Gender and Education Among People Living with HIV in China

Social support promotes positive coping strategies among people living with HIV (PLH); however, little is known about the various aspects of social support and their distinct effects on coping. The present study investigates the specific links between coping and perceived social support with respect to gender and education among PLH. A total of 522 PLH in Anhui, China, participated in an assessment that collected data on demographics, perceived tangible and emotional support, and cognitive and behavioral coping. The assessment was conducted using the computer-assisted personal interviewing method. The data were analyzed using linear mixed models. Emotional support was significantly associated with both cognitive and behavioral coping. Tangible support was significantly associated with behavioral coping but not with emotional coping. Women reported significantly lower levels of emotional support, cognitive coping, and behavioral coping than men did. Significant associations between tangible support and coping were found only among illiterate males. Women living with HIV are in greater need of social support and coping strategies. Future interventions should be gender specific, with targeted support for women with lower education levels to enhance their coping strategies

A Structural Equation Model of HIV-Related Stigma, Racial Discrimination, Housing Insecurity and Wellbeing among African and Caribbean Black Women Living with HIV in Ontario, Canada

African and Caribbean Black women in Canada have new HIV infection rates 7 times higher than their white counterparts. This overrepresentation is situated in structural contexts of inequities that result in social, economic and health disparities among African and Caribbean Black populations. Economic insecurity is a distal driver of HIV vulnerability, reducing access to HIV testing, prevention and care. Less is known about how economic insecurity indicators, such as housing security, continue to influence the lives of women living with HIV following HIV-positive diagnoses. The aim of this study was to test a conceptual model of the pathways linking HIV-related stigma, racial discrimination, housing insecurity, and wellbeing (depression, social support, self-rated health). We implemented a cross-sectional survey with African and Caribbean Black women living with HIV in 5 Ontario cities, and included 157 participants with complete data in the analyses. We conducted structural equation modeling using maximum likelihood estimation to evaluate the hypothesized conceptual model. One-fifth (22.5%; n = 39) of participants reported housing insecurity. As hypothesized, racial discrimination had significant direct effects on: HIV-related stigma, depression and social support, and an indirect effect on self-rated health via HIV-related stigma. HIV-related stigma and housing insecurity had direct effects on depression and social support, and HIV-related stigma had a direct effect on self-rated health. The model fit the data well: χ2 (45, n = 154) = 54.28, p = 0.387; CFI = 0.997; TLI = 0.996; RMSEA = 0.016. Findings highlight the need to address housing insecurity and intersecting forms of stigma and discrimination among African and Caribbean Black women living with HIV. Understanding the complex relationships between housing insecurity, HIV-related stigma, racial discrimination, and wellbeing can inform multi-level interventions to reduce stigma and enhance health
