Nonresponse in repeat population-based voluntary counseling and testing for HIV in rural Malawi

Despite the increasing number of population-based surveys in sub-Saharan Africa that provide testing and counseling for HIV over the past decade, understanding the nature of nonresponse in these surveys, especially panel HIV surveys, is still limited. This article uses longitudinal HIV data collected from rural Malawi in 2004 and 2006 to examine nonresponse in repeat population-based testing. It shows that nonresponse in repeat testing led to significant bias in the estimates of HIV prevalence and to inconsistent conclusions about the predictors of HIV status. In contrast, previous cross-sectional analyses found that nonresponse does not significantly bias the estimates of HIV prevalence. The difference in conclusions from cross-sectional and longitudinal analyses of nonresponse can be attributed to two factors: the different definitions of what constitutes nonresponse in both contexts, and the risk profiles of the missed populations. In particular, although refusal and temporary absence are the major sources ofnonresponse in the cross-sectional contexts, attrition attributable to mortality and out-migration are additional sources of nonresponse in repeat testing. Evidence shows that out-migrants have higher HIV prevalence than nonmigrants, which could account for significant bias in the estimates of prevalence among participants in both tests observed in this study.     

The municipal solid waste and the quality of life of collectors of recyclable materials in Juiz de Fora, Minas Gerais

The generation growing and diversified of Municipal Solid Waste is configured as an environmental problem, economic and social deterioration, especially, by application of inappropriate management of them. Faced with this urban context, the research in development presents as specific objective assessment of the quality of life of the gatherers of recyclable materials were active in the city of Juiz de Fora, in the brazilian state of Minas Gerais. In addition, the objective is, still, the recognition of the activity of sorting performed by "scavengers" in order to maximize the reduction, reuse and recycling energy and material waste daily. The proposed methodology is based on the application of the questionnaire Word Health Organization Quality of Life (WHOQOL-100), prepared by the World Health Organization, in order to value the quality of life of the gatherers of recyclable materials, involved, even in educational workshops in order to discuss and organize strategies of health care and scouting to the basement to public policies.     

The role of The Boffin as abject Other in gendered performances of school achievement

The gendered subjectivities of high achieving school pupils are examined, demonstrating the uneasy relationship between high educational achievement and peer popularity. Drawing on data from a study involving classroom observation and interviews with 71 high-achieving pupils across nine secondary schools in England, the article focuses on the gendered construction of The Boffin. Judith Butler's work, and Hannah Arendt's conception of pariahs and parvenus, are applied to analyse The Boffin as pariah, and as 'queer' in the classroom. The article explores the ways in which this construction is gendered, and the consequences of its application for girls and boys. It is argued that application of this stigmatised term functioned as a powerful deterrent to 'excessive' performances of achievement, for all pupils. But the risks are particularly acute for boys, to whom the 'naming' of Boffin appeared more readily applied, and for whom marginalization as Boffin appears especially perilous (risking particularly pernicious forms of punishment at the hands of other boys).     

Men's psychological functioning in the context of women's breast cancer

Previous research indicates that men are affected when their female partners have breast cancer. However, little is known about what predicts men's psychological well-being in this context. The current investigation involved couples in which the woman had early stage breast cancer and explored the degree to which men's positive and negative well-being was related to women's well-being, women's physical symptoms, relationship functioning, and relationship duration. The findings indicate that all of these factors play a role and interact in predicting men's well-being. In particular, when women have a high level of physical symptoms, the typical associations between men's well-being with women's well-being and relationship adjustment no longer persist. Implications for working with couples addressing health problems are provided.     

Standards of Care in Assessment of Lesbian,Gay, Bisexual,Transgender, Gender Expansive,and Queer/Questioning (LGBTGEQ+) Persons

ABSTRACT

A Joint Task Force comprised of members of the Association for Lesbian, Gay, Bisexual, and Transgender Issues in Counseling (ALGBTIC) and the Association for Assessment and Research in Counseling (AARC) present standards of care for assessment of Lesbian, Gay, Bisexual, Transgender, Gender Expansive, and Queer/Questioning (LGBTGEQ+) Persons.     

Proposing an Initiative Research Methodology for LGBTQ+ Youth: Photo-Elicitation and Thematic Analysis

ABSTRACT

A framework for approaching lesbian, gay, bisexual, transgender, queer+ (LGBTQ+) youth is presented that honors their voice. This methodology utilizes participant-driven photo elicitation as a qualitative data collection method, and then integrates thematic analysis. A brief review of current literature is provided to outline gaps, which establish the need to expand effective research methods with LGBTQ+ youth. Photo elicitation is explained with discussion specific to use with LGBTQ+ youth. Thematic analysis is identified and explained as an analytic approach. Challenges of implementing this methodology are discussed with attention to ethical concerns.     

The struggle for hegemony: the emergence of a counter-public sphere in post-1997 Hong Kong

The present study examines the struggle for hegemony in the public sphere by two different systems, following Hong Kong’s handover to China in 1997. It has been postulated that the new media, particularly social media, has become an important public sphere for the citizens of Hong Kong to engage in an anti-hegemonic struggle against China’s discursive encroachment into Hong Kong since 1997. Given that the public platform provided by legacy media has been bought out or coopted by China, new media has begun to serve as a subaltern public sphere to enable resisting the hegemony imposed by China. This was analyzed through a survey conducted as part of this study, which showed that people who are young, read the Apple Daily, have high expectations of local autonomy, and a high regard for press freedom are prone to using social media to obtain their social and political information. This article analyzes the implications of the emergence of a counter-China hegemonic public sphere.     

A study on imbalance support vector machine algorithms for sufficient dimension reduction

Li et al. (2011 Li, B., Artemiou, A., Li, L. (2011). Principal support vector machine for linear and nonlinear sufficient dimension reduction. Ann. Stat. 39:3182–3210.[Crossref], [Web of Science ®] , [Google Scholar]) presented the novel idea of using support vector machines (SVMs) to perform sufficient dimension reduction. In this work, we investigate the potential improvement in recovering the dimension reduction subspace when one changes the SVM algorithm to treat imbalance based on several proposals in the machine learning literature. We find out that in most situations, treating the imbalanced nature of the slices will help improve the estimation. Our results are verified through simulation and real data applications.     

Modified linear programming and class 0 bounds for graph pebbling

Given a configuration of pebbles on the vertices of a connected graph G, a pebbling move removes two pebbles from some vertex and places one pebble on an adjacent vertex. The pebbling number of a graph G is the smallest integer k such that for each vertex v and each configuration of k pebbles on G there is a sequence of pebbling moves that places at least one pebble on v. First, we improve on results of Hurlbert, who introduced a linear optimization technique for graph pebbling. In particular, we use a different set of weight functions, based on graphs more general than trees. We apply this new idea to some graphs from Hurlbert’s paper to give improved bounds on their pebbling numbers. Second, we investigate the structure of Class 0 graphs with few edges. We show that every n-vertex Class 0 graph has at least \(\frac{5}{3}n - \frac{11}{3}\) edges. This disproves a conjecture of Blasiak et al. For diameter 2 graphs, we strengthen this lower bound to \(2n - 5\), which is best possible. Further, we characterize the graphs where the bound holds with equality and extend the argument to obtain an identical bound for diameter 2 graphs with no cut-vertex.
