Maternal and neonatal helath in Africa at MDG end : availabiliy of and access to maternal health services, and outcomes of intervention strategies
No full textBackground: There is a need to provide increased evidence on effective interventions to reduce maternal and neonatal mortality in low- and middle-income countries (LMICs). Objectives: To summarize the breadth of knowledge on using routine data (Routine Health Information Systems [RHIS] and Intermittent Community Surveys [ICS]) forwell-designed maternal and neonatal health evaluations inLMICs. Search strategy:We searched reports and articles published inEmbase, Medline, and Google scholar. Selection criteria Studieswere considered for inclusion if they were carried out in LMICs, using RHIS or ICS data with experimental or quasi-experimental design. Data collection and analysis: A form was used to collect information on indicators used for interventions’ impact assessment. Descriptive statistics and multiple correspondence analyses were then performed. Main results: Of the 1201 publications identified, 46 studies met the inclusion criteria. Most of these were using RHIS data (n=40), mainly extracted from health facility registers (n=34), and non-controlled before and after design (n=30). The indicators, which were mostly reported, were related to the use of healthcare services (n=36) and maternal/neonatal health outcomes (n=31). Few studies used ICS data (n=6) or indicators of severity (n=2). Conclusion: RHIS and ICS data should be increasingly used for impact studies on maternal and neonatal health in LMICs
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
Maternal and neonatal helath in Africa at MDG end : availabiliy of and access to maternal health services, and outcomes of intervention strategies
No full textObjective: To determine the components of initial management associated with a decreased risk of severe postpartum hemorrhage (PPH) in Benin and Mali. Methods: A cohort study was conducted between May 2013 and September 2014 that included all women who delivered vaginally in seven participating centers and who presented excessive bleeding after birth. Severe PPH was defined as PPH that required surgical treatment (vascular ligature and/or hysterectomy), and/or blood transfusion, and/or transfer to an intensive care unit, and/or an outcome of maternal death. Logistic regression was used to identify the components of initial PPH management that were associated with severe PPH, adjusting for case mix. Results: A total of 223 women presented a primary PPH presumably caused by uterine atony. Among those, 88 (39.5%) had severe PPH. Nearly one-third of women (30.4%) had a late injection of oxytocin (N10 minutes) after PPH diagnosis or no injection. Oxytocin injection within 10 minutes after the PPH diagnosis was significantly associated with a decreased risk of severe PPH (adjusted OR=0.3; 95% CI, 0.14–0.77). Conclusion: Decrease in the delays in oxytocin administration is a key determinant to improve maternal outcomes related to PPH in this context
