    Is lack of breakfast contributing to nutrient deficits and poor nutritional indicators among adolescent girls?

    Background: Breakfast is considered the first and most important meal of the day. Missing the first meal may result in significant nutritional deficits, if not compensated in subsequent meals. Aim: To describe the nutrient intake through breakfast and to study its association with nutritional indicators among adolescent girls. Methods: A cross-sectional study among adolescent girls ( n = 565) 16–18 years was carried out in urban slums of Pune, Maharashtra, India. Haemoglobin was assessed by cyanmethemoglobin method. Nutritional status was assessed through anthropometry and three 24-hours diet recall. Z scores, independent sample test, and linear logistic regression were used to assess undernutrition, to compare means of nutrient intake and to associate nutrient intake with nutritional status, respectively. Results: Almost 50% did not consume solid food for breakfast and 99% of the participants consumed inadequate breakfast (&lt;610 kcal). Two types of breakfast emerged: I (bakery products + beverage) and II (traditional breakfast + beverage). Although the mean energy intake of type II breakfast (235±100.55 kcal) and the mean micronutrient intake was significantly higher than type I (micronutrients: vitamin C and folate ( p = 0.001), iron ( p = 0.01)) it did not meet the adequacy norms for breakfast. Among nutritional indicators breakfast intake was not directly associated with body mass index. However, mean intake of nutrients such as energy, protein and iron through the day were significantly lesser ( p = 0.001, p = 0.01 and p = 0.01 respectively) among anaemic adolescents. Linear regression showed significant association between energy, fat intake and BAZ scores. Conclusions: Compensating dietary deficits that arise in the first meal would directly address the day’s nutrient deficit. The results highlight the need for a food-based approach to address undernutrition among adolescent girls in resource-poor settings. </jats:sec

    Assessment of personal hygiene and sanitation using a composite index among adolescent girls and their households in urban slums of Pune, Maharashtra

    The assessment of hygiene and sanitation in urban slums is essential to identify adolescent health needs. A tool that comprised of three domains and 13 variables including drinking water index (DWI), personal hygiene index (PHI) and household hygiene index (HHI) was developed and tested among 60 households. Observations were repeated after 6 weeks. Cronbach's alpha was used to test the reliability and Inter Class Correlation Coefficient was used to assess repeatability of the questionnaire. The tool was used to assess the personal hygiene of adolescent girls (n = 565) and their household sanitation in nine slums of Pune city. Excellent reliability (α = 0.9) was obtained for four variables, two observations obtained good (α = 0.8), two scored acceptable (α = 0.7) and one scored questionable (α &amp;lt; 0.6) reliability. No variance was observed among four variables. DWI and PHI scores were average (between 2 and 3). About 40% of the households scored the least (between zero to one) in HHI. History of malaria was reported among 3%, one year prior to the study period and 30% minor infections were reported. The composite index developed was valid to assess hygiene and sanitation of this population. Measures to improve household hygiene would contribute to integrated approaches in improving adolescent health.</jats:p

    Going Beyond Counting First Authors in Author Co-citation Analysis

    The 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

    “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

    We 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

    We 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 text
    We 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
