Know your HIV epidemic (KYE) report: review of the HIV epidemic in South Africa.
No full textIn order to update and consolidate South Africa’s evidence base for HIV-prevention interventions, it was decided by the Government of South Africa to commission a synthesis of the available data on the epidemiology of prevalent and incident HIV infections, and the wider epidemic context of these infections. This know your epidemic (KYE) approach has been successfully implemented in a number of sub-Saharan African countries.2 The process involves a desk review and secondary analysis of existing biological, behavioural and socio-demographic data in order to determine the epidemiology of new HIV infections. KYE reports present key findings and policy and programme recommendations which are grounded in local evidence and aim to support decision-making and improve HIV-prevention results. In 2010, South Africa also conducted a know your response (KYR) review, which critically assessed HIV-prevention policies, programmes and resource allocations. The overall results of this HIV epidemic review and the KYR review will be published in a separate, national KYE/KYR synthesis report
Homelessness, Mental Health and Resilience of Young People Transitioning from Out-of-Home Care
Full text linkYoung people transitioning from out-of-home care often experience poor long-term outcomes, including mental health and homelessness. This project used integrated administrative and longitudinal data from Victoria and Western Australia, with growth mixture modelling revealing subgroups with distinct trajectories of mental health and homelessness. Structural equation modelling revealed mediating and moderating factors influencing resilience. There is need for targeted, trauma-informed interventions to address the complex challenges faced by this population
Impact Evaluation on Improving Voluntary Medical Male Circumcision Demand in Malawi through the Use of Incentives
No full textThis report presents an impact
evaluation assessing the effect of incentives on improving
the uptake of Voluntary Medical Male Circumcision (VMMC) in
two districts in Malawi. The cluster randomised control
trial was led by the National AIDS Commission of Malawi and
implemented from December 2015 to April 2016. The primary
research question was whether incentives can increase VMMC
uptake among in-school and out-of-school males aged 10-34.
Collective incentives (e.g. whiteboards, football equipment)
to schools and Mothers’ Groups, as well as individual
incentives in the form of vouchers for VMMC were tested. The
evaluation found that incentives in the form of vouchers for
VMMC work. The vouchers had a significant positive impact on
VMMC demand by increasing the odds of getting circumcised by
over seven times. Secondary distribution by voucher
recipients showed potential to informally increase
distribution networks without increasing costs. There was
some evidence of spill-over to relatives: nearly a third of
participants in both study districts who had been given
vouchers reported that they gave vouchers to relatives.
Using the participants’ own social networks had the result
of expanding the reach of the intervention without
additional distribution costs. The evaluation also found
that community-involvement, especially in the form of
Mothers’ Groups, was essential to motivate young men to seek
VMMC. The report discusses the policy implications of this
positive finding of incentives
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
koamabayili/VECTRON-author-checklist: VECTRON author checklist
No full textWe have done our best to complete the author checklist relating to the use of animals in the hut study. Note that the objective for the hut study was to evaluate the IRS treatment applications for residual efficacy against Anopheles mosquitoes, including the local An. coluzzii mosquito population. Cows were only used to attract mosquitoes into the huts and no tests were carried out directly on the cows. The author checklist is intended for use with studies where experiments are carried out on animals, which is why we have had such difficulty in completing this for the hut study, as many of the questions do not relate to how the cows were used
