While multiple studies have documented shifting educational gradients in HIV prevalence, less attention has been given to the effect of school participation and academic skills on infection during adolescence. Using the Malawi Schooling and Adolescent Study, a longitudinal survey that followed 2,649 young people aged 14–17 at baseline from 2007 to 2013, we estimate the effect of three education variables: school enrolment, grade attainment, and academic skills—numeracy and Chichewa literacy—on herpes simplex virus type 2 (HSV-2) and HIV incidence using interval-censored survival analysis. We find that grade attainment is significantly associated with lower rates of both HSV-2 and HIV among girls, and is negatively associated with HSV-2 but not HIV among boys. School enrolment and academic skills are not significantly associated with sexually transmitted infections (STIs) for boys or girls in our final models. Efforts to encourage school progression in high-prevalence settings in sub-Saharan Africa could well reduce, or at least postpone, acquisition of STIs.  相似文献

Much contemporary debate about pornography centers on its role in portraying and perpetuating gender inequality. This article compares traditional gendered attitudes between cisgender men attending the Adult Entertainment Expo (n = 294) and a random sample of male respondents from the 2016 General Social Survey (GSS), a U.S. representative survey of general attitudes and beliefs collected every two years (n = 863). Our survey borrowed questions from the GSS to measure attitudes about gender equality across four dimensions: (1) working mothers, (2) women in politics, (3) traditional gender roles in the family, and (4) affirmative action for women in the workplace. Through bivariate analyses, we found that “porn superfans” are no more sexist or misogynistic than the general U.S. public on two of the four measures (women in politics and women in the general workplace) and held more progressive gender‐role attitudes than the general public on the other two measures. We conducted binary logistic regressions for those two measures to determine if the relationship remained significant when controlling for other factors. For one dimension, working mothers, it did (p < .001). Our results call into question some of the claims that porn consumption fosters de facto negative and hostile attitudes toward women.  相似文献

We study the benefit of exploiting the gene–environment independence (GEI) assumption for inferring the joint effect of genotype and environmental exposure on disease risk in a case–control study. By transforming the problem into a constrained maximum likelihood estimation problem we derive the asymptotic distribution of the maximum likelihood estimator (MLE) under the GEI assumption (MLE‐GEI) in a closed form. Our approach uncovers a transparent explanation of the efficiency gained by exploiting the GEI assumption in more general settings, thus bridging an important gap in the existing literature. Moreover, we propose an easy‐to‐implement numerical algorithm for estimating the model parameters in practice. Finally, we conduct simulation studies to compare the proposed method with the traditional prospective logistic regression method and the case‐only estimator.

Although Vietnamese society is currently undergoing significant changes with regards to the rights and perceptions of gay, lesbian, bisexual, transgender, and queer (GLBTQ) people, dominant socio-cultural norms related to gender, sexuality, and the importance of the patrilineal family regime continue to cast a shadow over the lives of GLBTQ in contemporary Vietnam. Based on ethnographic fieldwork conducted in the urban centers of Hanoi and Ho Chi Minh City, as well as legal documents and secondary sources, this article illustrates how dominant heteronormative socio-cultural norms have contributed to the political, legal, and social exclusion of same-sex sexualities through a process of outlawing, whereby GLBTQ have been systematically excluded from the rights of law. Drawing on qualitative interviews with gay men and lesbian women between the ages of 20 and 50, the article also highlights how this relation of domination has allowed for instances of GLBTQ resistance, through subversive opposition, strategies of avoidance, and the seeking out of new opportunities in urban spaces outside the dominant sociality. The article thus provides a qualitatively nuanced account of family politics and GLBTQ resistance in urban Vietnam at a significant socio-political historical juncture.  相似文献

The role of financial counsellors as providers of information, support and advocacy for those in financial difficulty is a well established mechanism in the mainstream welfare landscape in Australia. In general, the role of financial counsellors is in helping people alleviate or resolve their financial difficulties through improvement of their financial literacy. It is recognised as an important component of policy responses to assist low‐income households and individuals in financial stress. The use of financial counsellors for older persons (i.e., those aged 65+ years), however, appears to be underutilised. Financial hardship and abuse of older persons within our community are becoming key issues as the population of Australia “ages”. Existing evidence also suggests that service providers alone do not have adequate skills to address these issues. This paper firstly examines the development of financial counselling in Australia. It then examines the newly emerging role of financial counselling in supporting older persons in addressing barriers to financial literacy and then in navigating the complex landscape of aged care service provision. The current financialisation, marketisation and complexities of consumer‐directed care are identified as key contextual factors. The paper will then discuss an evaluation study of the provision of financial counselling to the older person population designed to support financial hardship and navigation of the complex aged care services system. The findings of the paper are based on an evaluation of the Financial Consumer Rights Council (FCRC), Victoria: Dignity and Debt Financial Difficulty and Getting Older initiative. This pilot initiative included older persons from both community‐based and aged care residential facilities in one regional area of Victoria. The initiative, conducted over 2016, was designed to assess the effectiveness of one‐on‐one financial counselling sessions with older persons that provided consumer advocacy and information about support services and entitlements (including hardship protections) associated with ageing. The evaluation found that the provision of financial counselling to the older person population could be a key mechanism in improving overall financial literacy, avoiding periods of financial hardship and in maintaining financial well‐being, quality of life and positive ageing. Findings also demonstrated a need for an expanded outreach financial counselling model to better service older persons in more isolated living environments and/or with mobility impairments living in the community, and the potential to situate offices of financial counsellors within medical centres (a space often visited by the ageing population), to co‐situate financial health check‐ups as an overall element of health and well‐being. As such, financial counselling was viewed as well placed to support older persons in improvement of financial literacy and in supporting navigation of the increasingly complex marketised and consumer‐directed care (CDC) landscape of aged care service provision in Australia.  相似文献

This paper uses conceptual resources drawn from psychosocial process thinking (Brown & Reavey, 2015; Brown & Stenner, 2009; Stenner, 2017) and from G.H. Mead in particular, to contribute to an emerging body of work on the experiences of adult women with ADHD (Horton‐Salway & Davies, 2018; Quinn & Madhoo, 2014; Singh, 2002; Waite & Ivey, 2009). It has a particular focus on how ADHD features in the construction of women's identities and life‐stories and it draws upon findings from a qualitative investigation of adult women diagnosed or self‐diagnosed with Attention Deficit Hyperactivity Disorder (ADHD). A theoretically informed ‘thematic decomposition’ of 16 depth interviews reveals how complex processes of identity transformation are mediated by the social category of ADHD. Through this process, troubled pasts are reconstructed from the perspective of an ‘emergent’ identity that offers participants the potential for a more enabling and positive future.  相似文献

Investments in protective measures involve an initial immediate cost in exchange for a stream of potential benefits accruing over time in the form of reduced expected losses. This paper describes two studies in which individuals were asked both to make choices and indicate the maximum amount they were willing to pay (WTP) for such protective measures. By varying the number of years that the measures provided protection, we observed four different decision strategies that individuals use to determine their maximum WTP. The findings from these experiments strongly suggest that most individuals do not take into account the added benefits of having a protective measure in place over a longer period of time when determining the likelihood of purchasing protection or the maximum price they are willing to pay. The behavior of a relatively small proportion of the subjects was consistent with a discounted utility model. Most subjects were either myopic in their behavior or did not change their maximum WTP as the time horizon changed. Despite the fact that most subjects were insensitive to time changes, they were generally willing to purchase the protective measures. Implications of these results for investment in risk mitigation measures are briefly explored.  相似文献
