A systematic review of counselling for HIV testing of pregnant women

JOURNAL OF CLINICAL NURSING, Issue 13 2009
Karin S Minnie
Background., Evidence-based strategies have made it possible to limit mother-to-child transmission of the HI-virus to a large extent and enable HIV-positive women to stay healthy for longer, provided their HIV status is known. Although voluntary counselling and testing for HIV is part of routine antenatal care in South Africa, the uptake of testing varies and a large number of pregnant women's HIV status is not known at the time of birth. Aim., The aim of the study was to establish research evidence regarding factors influencing counselling for HIV testing during pregnancy by means of systematic review, forming part of a larger study using a variety of evidence to develop best practice guidelines. Design., Systematic review. Methods., The question steering the review was: ,What factors influence counselling for HIV testing during pregnancy?'. A multi-stage search of relevant research studies was undertaken using a variety of sources. A total of 33 studies were retrieved and critically appraised. Data were extracted from the studies and assessed according to its applicability in the South African context. Results., The results are presented according to the following themes: effects of counselling, quality of counselling, group vs. individual counselling, ways of offering HIV testing, rapid testing, counselling and testing during labour, couple counselling and testing, counsellor and organisational factors. Conclusions., According to research evidence, factors such as whether counselling is presented in a group or individually, different ways to present HIV testing as well as counsellor and organisational factors can influence counselling for HIV testing during pregnancy. When developing best practice guidelines for settings very dissimilar from where the research was done, research evidence must be contextualised. Relevance to clinical practice., Implementation of the best practice guidelines may lead to the increased uptake of HIV testing in pregnancy in developing countries like South Africa and thus to an increase in the number of women whose status is known when their babies are born.

A judicial presentation of evidence of a student culture of "dealing"

JOURNAL OF RESEARCH IN SCIENCE TEACHING, Issue 4 2009
Nathan B. Wood
Abstract This study uses a new-to-educational-research methodology, based on the legal process, to build a case that U.S. students have been largely ignored in discussion and planning for their own, presumed futures. A variety of evidence, from two large and distinct data bases, is drawn together to show: (1) students perceive their classrooms in ways distinctly different from the ways in which teachers perceive the same classrooms, (2) students' values are fundamentally different from teachers', (3) student and teacher cultures work together to perpetuate the status quo, and (4) existing educational policy, and the research on which it is based, does not adequately consider student culture. A global student culture of "dealing" is described and it is argued that this culture is an underlying cause of the deterioration in the achievement of U.S. students and the failures of so many reform efforts to bring about substantial and lasting change. © 2009 Wiley Periodicals, Inc.

Xmrks the spot: life history tradeoffs, sexual selection and the evolutionary ecology of oncogenesis

MOLECULAR ECOLOGY, Issue 15 2010
KYLE SUMMERS
In a classic paper, George Williams (1957) argued that alleles promoting reproductive success early in life may be favoured by selection, even if they reduce the lifespan of individuals that bear the allele. A variety of evidence supports the theory that such ,antagonistic pleiotropy' is a major factor contributing to the evolution of senescence (Ljubuncic & Reznick 2009), but examples of specific alleles known to fulfil Williams' criteria remain rare, in both humans and other animals (e.g. Alexander et al. 2007; Kulminski et al. 2010). An intriguing example in this issue of Molecular Ecology (Fernandez & Bowser 2010) demonstrates that both natural and sexual selection may favour melanoma-promoting oncogene alleles in the fish genus Xiphophorus.

Governmental and accrediting entities are demanding increased accountability and efficiency from colleges and universities. This chapter discusses strategies for developing institutional data sets that create a "culture of evidence." [source]

Are the Japanese Selfish, Altruistic or Dynastic?

THE JAPANESE ECONOMIC REVIEW, Issue 1 2002
Charles Yuji HoriokaArticle first published online: 18 DEC 200
I analyse a variety of evidence for Japan and, where available, for the United States on bequest practices, the importance and nature of bequest motives, bequest division, the willingness of individuals to help others, etc., in order to shed light on which model of household behaviour applies in the two countries. My results suggest that the selfish lifecycle model is the dominant model of household behaviour in both countries but that it is far more applicable in Japan; that the dynasty model is also more applicable in Japan but is not of dominant importance even there; and, conversely, that the altruism model is far more applicable in the USA.
