Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe 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
Impact de la participation à un jardin partagé en ville sur l’adoption de styles de vie plus durables
No full textThe creation of urban community gardens is arousing growing interest among many stakeholders as a tool for improving the physical, mental and social health of city dwellers while contributing to the sustainable development of cities. The objective of this thesis was to determine whether community gardens can be an effective tool to promote the health of urban residents, but also more sustainable lifestyles, in a French context. A systematic literature review on the relationship between urban community garden participation and health in general adult population highlighted the limitations of the existing literature dominated by cross-sectional studies, based on self-reported measures and conducted in North-American context. The JArDinS quasi-experimental study was implemented to evaluate the effect of the first year of community gardening on the sustainability of the gardeners' monthly household food supplies (nutritional quality, environmental impact and cost), gardeners’ level of physical activity, their mental and social well-being, as well as their sensitivity to food waste and their connection to nature. We did not find a positive impact of participating in a community garden on the investigated variables. These findings are supported by a qualitative evaluation that highlights barriers and limitations of existing gardens. At a time when many cities are turning their attention to the development of community gardens on their territories, this thesis calls for new forms of community gardens that would favour the integration and long-term participation of individuals with a variety of cultural and socio-economic profiles. An evaluation of these new gardening formats through intervention studies will provide evidence of the relevance of using community gardens to accompany the urban population towards the adoption of more sustainable lifestyles.La création de jardins partagés urbains suscite un intérêt croissant de nombreux acteurs qui y voient un levier pour améliorer la santé physique, mentale et sociale des citadins tout en contribuant au développement durable des villes. L’objectif de cette thèse était de déterminer si les jardins partagés peuvent être un outil efficace pour promouvoir la santé des citadins, mais aussi des styles de vie plus durables, dans un contexte français. Une revue systématique de la littérature sur le lien entre la participation à un jardin collectif urbain et la santé en population générale adulte a souligné les limites de la littérature existante dominée par des études transversales, basées sur des déclarations et menées dans un contexte nord-américain. L’étude quasi-expérimentale JArDinS a été mise en place afin d’évaluer l’effet de la première année de jardinage sur la durabilité des approvisionnements alimentaires mensuels des foyers des jardiniers (qualité nutritionnelle, impact environnemental et coût), le niveau d'activité physique des jardiniers, leur bien-être mental et social, ainsi que leur sensibilité au gaspillage alimentaire et leur lien avec la nature. Notre étude n’a pas mis en évidence d’impact positif de la participation à un jardin partagé sur les variables mesurées. Ces résultats sont appuyés par une évaluation qualitative qui souligne les freins et limites des jardins existants. A l’heure où de nombreuses villes envisagent d’implanter des jardins partagés sur leurs territoires, cette thèse invite à réfléchir à de nouvelles formes de jardins partagés qui favoriseraient l’intégration et la participation active sur le long terme d’individus ayant des profils culturels et socioéconomiques variés. Une évaluation de ces nouveaux formats de jardinage au moyen d’études interventionnelles fournira des preuves de la pertinence ou non d’utiliser les jardins partagés pour accompagner la population urbaine vers l’adoption de styles de vie plus durables
Variations on the Author
Get PDF“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
Get PDFWe 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
Get PDFWe 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
