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
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

Agricultural Risks and Social Vulnerability in Rural Areas in The Commune of Houéyogbé in South-Benin
Get PDFThe present research aims at studying the social vulnerability of the agricultural risks in the Commune of Houéyogbé The methodological step used is articulated around the analysis and, their treatment data-gathering of the results. The data-gathering consisted of the information retrieval and of investigation of ground by using the individual talks and the method of x-ray group. The statistics heights of rains and the data hydrometric of the period 1981-2010 then the pedo-geomorphological and agricultural data of same period (SCDA Houéyogbé) made it possible to study the agricultural risks The data and information resulting from the information retrieval and the socio-anthropological investigations made it possible to apprehend the social vulnerability of the rural populations to the agricultural risks.¶The matrix of appreciation of the vulnerability made it possible to determine the current and future vulnerability rural communities (for example, the level of high impact and low capacity of adaptation give the high level of vulnerability).¶With the latter, the strategies of mitigation locally installation are added (early harvest, temporary migration towards the no flooded grounds, etc).¶Moreover, the data and information relating to the agricultural risk management collected with the seat of the specialized organizations such as the ANPC and Caritas-Benign made it possible to propose suitable mechanisms of management.
Atouts et Contraintes Lies à la Production de la Patate Douce (Ipomoea Batatas) dans la Commune de Sô-Ava au Benin
No full textRésuméL’agriculture occupe désormais le devant de la scène internationale, du fait des crises alimentaires récentes et des préoccupations croissantes liées à la démographie galopante. La présente étude vise à contribuer à une meilleure connaissance liée à la production de la patate douce dans la commune de Sô-Ava au Bénin. Les données utilisées dans le cadre de cette étude sont à la fois qualitatives et quantitatives. Il s’agit notamment des statistiques climatologiques (pluie, ETP et températures maxi et mini) et agricoles ainsi que celles relatives aux contraintes liées à cette activité recueillie auprès des producteurs lors des enquêtes qui ont lieu dans quatre arrondissements de la commune. Il ressort de l’analyse des résultats obtenus que la commune de Sô-Ava dispose de bons nombres de conditions biophysiques favorables à la production de la patate douce. Les contraintes qui handicapent la production de la patate douce sont : les aléas climatiques, la conservation des racines, les insectes ravageurs, la non organisation des producteurs, etc. Face à cette situation de nouvelles stratégies doivent être développées pour un meilleur développement de la filière patate douce dans la commune de Sô-Ava.Mots clés : Commune de Sô-Ava, production et commercialisation, patate douce, économie, contraintes AbstractAgriculture is now at the forefront of the international scene, due to recent food crises and growing concerns related to rampant demography. This research aims to contribute to a better knowledge related to the production of sweet potato in the commune of Sô-Ava in Benin. The data used in this study are both qualitative and quantitative. These include climatological (rain, FTE and maximum and minimum temperatures) and agricultural statistics as well as those relating to the constraints linked to this activity collected from producers during surveys which take place in four districts of the municipality. Analysis of the results shows that the municipality of Sô-Ava has many biophysical conditions favorable to the production of sweet potato. The constraints which handicap the production of sweet potato are : climatic vagaries, conservation of tubers, insect pests, non-organization of producers, etc. Faced with this situation, new strategies must be developed for better development of the sweet potato industry in the Municipality of Sô-Ava.
