No full textEpidemiological transition and double burden of diseases in low-income countries: The case of Mozambique
No full textEpidemiological transition theory aims to describe changes in epidemiological scenarios at the global and national level. The assumption is the shift from infectious diseases (IDs) to non-communicable diseases (NCDs). Some authors argue that this theory failed to describe epidemiology in sub-Saharan Africa. We considered the case of Mozambique, where is occurring a rapid demographic change, with dramatic growth of the population. According to the data, we concluded that NCDs are increasing in Mozambique, but due to the vast predominance of IDs, a double burden of disease model is more accurate to describe the actual epidemiological context of the country. Consequently, health funding focusing on IDs should take into account the concomitant epidemiological scenario and try to encompass other health challenges
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
The effectiveness of interventions to involve men living with HIV positive pregnant women in low-income countries: A systematic review of the literature
Full text linkBackground: Male involvement (MI) along the continuum of HIV healthcare services has been promoted as a
critical intervention in low-income countries and represents one of the reasons for dropout and low retention of
women along the cascade of care. The present review aims to identify interventions adopted to improve MI across
Antenatal Clinics (ANCs).
Methods: For this systematic review, we searched electronic databases, including Scopus, PubMed, Web of Science
(from 2008 to 2018) in English language. We included all interventions explicitly aimed at involving partners in
pregnant women’s HIV continuum of care and we excluded studies performed in developed countries, not
involving pregnant women. We followed the PRISMA checklist.
Results: We identified a total of 1694 records and excluded 1651 after duplicates were removed and abstract
eligibility assessments were performed. Forty-three full-text articles were screened, but only 12 studies were
included. Recurrent intermediate outcomes were antenatal partner attendance rate and male HIV testing. We
subdivided articles according to the type of intervention: single intervention (7) and multiple interventions (5).
Among single interventions, two studies evaluated the use of an invitation letter sent via women to encourage
male attendance to the ANC. Four Randomized Controlled Trials (RCTs) compared the invitation card (standard of
care, SC) to word of mouth, information letter, home visit and invitation card plus partner tracing. The partner
attendance rate was lower in SC than in the intervention arm in three RCTs: information letter (14.2% vs 16.2%),
home-visit (39% vs 87%) and invitation card plus partner tracing (52% vs 74%). Home visit strategies seemed the
most effective. One study evaluated words of encouragement adopted to trigger women to invite their partners.
Among multiple interventions, the most effective strategies in terms of male attendance included health promotion
through education and healthcare worker development. These interventions were more likely to be effective in
promoting MI than single interventions.
Conclusions: From the review emerges the importance of male involvement in HIV cascade for pregnant women
in countries with a significant HIV incidence and the need to define more precise indicators for measuring MI
