Full text linkThe “Pappa di Parma” integrated approach against moderate acute malnutrition
No full textThe use of Ready-to-Use Therapeutic Foods (RUTFs) is not a sustainable strategy to treat child moderate acute malnutrition due to its high cost and unfamiliarity. An integrated multidisciplinary approach called “Pappa di Parma” was used to develop, characterize and introduce alternative sustainable and energy-dense meals against malnutrition. Six formulations were developed by using basic accessible technologies and locally available ingredients (Tanzania), a daily portion of which meets RUTFs macronutrient requirements and most micronutrients RNI. Quality characterization, rheological properties and shelf-stability of formulae were assessed under different storage conditions disclosing the suitability and stability of no-water formulae in all tested storage conditions for almost under three months. Moreover, the cultural acceptance and the economical sustainability through the implementation in Tanzania were also evaluated. Overall, this study confirmed the “Pappa di Parma” approach as a valid starting point to sustainable alternatives to RUTFs, tailored to specific agricultural and socio-economic contexts
Understanding, promoting and predicting sustainable diets: A systematic review
Full text linkBackground: The understanding of consumers' behaviours is crucial for developing strategies and educational interventions necessary to transition towards more sustainable diets at the individual and population level. In this regard, social-psychological models can be effective in identifying and understanding the role of the cognitive constructs behind the consumers’ behaviour. Scope and approach: The present systematic review is aimed at identifying the main drivers and barriers towards the adoption of sustainable dietary behaviours in adult populations. Sixty-seven papers were analysed by applying at least one of the following three theoretical approaches: the Theory of Reasoned Action, the Theory of Planned Behaviour, and the Social Cognitive Theory. Key findings and conclusions: Most of the studies were conducted in industrialised countries and, with one exception, only one among health, environmental, socio-economic and qualitative dietary dimensions was considered in each study. The adoption (or the intention to adopt) a healthy or a low-fat diet was the most analysed. A multitude of significant predictors of intention and behaviour was found. The most recurrent predictors were attitude for intention and intention for behaviour. Social-psychological models can be relevant when applied to dietary behaviour contexts, but present limits in explaining behaviour when prospective and more objective tools to assess food consumption (e.g., food diaries and/or food frequency questionnaires) are used. By identifying the drivers of consumers’ behavioural changes, the collected results may support policy makers in providing recommendations and defining primary prevention interventions which enhance consumer awareness and engagement towards more sustainable dietary habits
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
