The missed HIV-positive children of Ethiopia
No full textObjective: As elsewhere, due to scarcity of data and limited awareness of HIV infection, especially in older children, the HIV epidemic among Ethiopian children appears neglected in national programs (children ART coverage is of only 12% in 2013). This paper estimates the country burden of HIV in older children and investigates the prevalence of HIV in orphans and vulnerable children (OVC) households. Design/Methods: We analyzed national HIV data for Ethiopia, using Spectrum/ Estimation and Projection Package (EPP) and primary data on children living in households with at least one HIV-positive adult in the Amhara and Tigrai regions. Descriptive analysis of the age and sex distribution of HIV-positive OVC in Ethiopia was performed. Results: Our Spectrum/EPP analysis estimated the population of HIV-positive children under 15 years old to be 160,000 in 2013. The majority of children (81•6%) were aged five to 14 years. The estimated number of orphans due to AIDS was 800,000. The empirical data from almost 10,000 OVC under 18 years showed 11•9% were HIV-positive, the majority of whom were between five and 10 years old with no significant difference between males and females. Conclusions: There is a large population of children living with HIV in Ethiopia, the magnitude of which not previously recognized. The majority were vertically infected and never identified nor linked into treatment. OVC represent a reachable group which could account for a substantial proportion of the HIV infected older children. We recommend that HIV programs urgently synergize with social protection sectors and address these children with HIV testing and related services
Health impacts amongst carers of orphans and other children in a high HIV prevalence community in South Africa
Full text linkFifteen million children have been orphaned by AIDS. A growing body of evidence documents impacts of parental deaths on orphans, but little is known about impacts faced by AIDS-orphan carers. This study set out to: (a) investigate physical and mental health outcomes of adults caring for children in Umlazi, a high HIV prevalence township in South Africa; (b) assess whether AIDS-orphan carers face worse outcomes compared to other carers; and, (c) identify risk and protective factors for health. Using a cross-sectional survey, data was gathered from a representative community sample from August 2008 to March 2009 resulting in the largest known study conducted on AIDS-orphan carers to date (n=1599). The majority of carers looked after non-orphaned children (66.85%) followed by AIDS-orphan (22.45%) and other-orphan children (10.69%). Orphan carers had significantly worse general health and functioning, depression, and post-traumatic stress than non-orphan carers but patterns were less clear when orphan carers were disaggregated into AIDS-orphan and other-orphan carers for comparison. This suggests that health interventions might target orphan carers, rather than singling out AIDS-orphan carers. Differences in age, gender, education, economic assets, and source of household income fully accounted for the association between being an orphan carer and poor health. Social policy grants reduced negative health disparities between orphan carers and non-orphan carers. Social support, education, economic assets, food, access to water, and housing were iii also identified as risk and protective co-factors that might reduce orphan carer disparities in health. By highlighting health as a serious issue for orphan carers and identifying risk and protective factors for health, this study offers policy and program insights into how to mitigate negative impacts faced by carers in high HIV prevalence communities facing escalating numbers of orphans
Role of family in HIV prevention: systematic reviews and qualitative investigation of young Thai women in Bangkok
Full text linkYoung women are particularly vulnerable to HIV. Despite the successful HIV prevention efforts in Thailand in the past, young Thai women are at increased HIV risk and in urgent need of effective HIV interventions. Numerous studies have emphasised the importance of family in determining young people’s sexual behaviour. This thesis explores the roles of family in shaping young people’s sexual decisions and examines the potential of family-involved HIV interventions (FIHIs) for young Thai women. The thesis systematically examines studies across settings to determine whether involving family in HIV interventions could influence young people’s sexual behaviour. The findings suggest that FIHIs have a potential in shaping young people’s condom use practices. It identifies several key characteristics of effective FIHIs that can potentially be valuable for future HIV development in other contexts. Qualitative data collected from focus groups of young Thai women in Bangkok are analysed using the framework developed from the systematic review of qualitative studies. The findings highlight several challenges for future FIHIs for young Thai women. These are barriers to parent-child communication, a tension of coexistence of two divergent sexual norms - traditional/Thai versus modern/globalised, alternative sources of sexual health and HIV knowledge, the importance of family relationships, and the different circumstances and needs of young Thai women from different backgrounds. Future FIHIs for young Thai women should consider a comprehensive, structural and eco-developmental approach, simultaneously targeting both individuals and the wider environment. This thesis offers a new contribution to the HIV prevention and sexual health education literature and identifies the potential effectiveness of FIHIs tailored to young Thai women,constituting an important step in addressing the public health problems of HIV/AIDS infections in Thailand
Sexual risk behaviors of African American men who have sex with men: implication of situational factors and partner dynamics
Full text linkHIV infection disproportionately burdens Black men who have sex with men (MSM) living in the United States. Qualitative research is able to richly contextualize the HIV risk factors of Black MSM, but to date limited qualitative evidence exists. This study set out to: (a) examine how participants perceived their childhood experiences to impact their adult sexual behaviors; (b) describe the situational context and the main perceived drivers of high and low risk behaviors, and contextualize these behaviors according to life circumstances at the time; and (c) explore participants' perceived sources of social support, and understand how the quality of this social support may influence participants' psychological well-being and HIV risk behaviors. Semi-structured in-depth interviews were conducted with 34 Black MSM in Providence, Rhode Island, USA. Thematic analysis sought to understand the factors contributing to an episode of protected sex and unprotected sex occurring within the previous 12 months. Narratives suggest that sexual risk behaviors are not isolated events, but instead the result of a lifetime of experiences that may influence attitudes and beliefs toward sexual safety, mental and emotional health, and self-efficacy for condom use. Participants perceived that: (a) interpersonal, internal/psychological, and episodic factors influenced their high risk and low risk sexual behaviors; (b) childhood socioeconomic status, family characteristics, and experiences of abuse were among the most important childhood factors implicated in their adult sexual behaviors; and (c) limited social support led to feelings of loneliness, isolation, and alienation, which may have led participants to seek intimacy through high-risk sexual episodes. This thesis suggests that complex interrelated factors underlie the sexual risk behaviors of Black MSM. Future HIV prevention efforts must extend beyond safer-sex approaches and address the social-ecological determinants of sexual behaviors. Further qualitative examination can deepen understanding of Black MSM’s sexual behaviors, provide meaningful insight into the factors driving unprotected sexual behaviors, and uncover novel points for intervention
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Variations on the Author
Full text link“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
Full text linkWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis

Dispelling the Myths Behind First-author Citation Counts
Full text linkWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
