Stratégies organisationnelles et capacité d’adaptation des coopératives agricoles dans un contexte de changement climatique : cas des coopératives agricoles du 2ème pôle de développement agricole au Bénin
No full textThis thesis aims to understand the mechanisms by which the organisational strategies implemented by agricultural actors favour the adaptation of agricultural cooperatives to the effects of climate change. An essentially qualitative methodological approach based on an interpretative positioning and an inductive reasoning mode was adopted. It consisted of conducting semi-directive and focus group interviews with seventy-three (73) actors from agricultural cooperatives involved in cotton, maize and market gardening production and with actors from the support and supervision structures of these cooperatives. At the end of the analyses, it emerged that the stakeholders of the agricultural cooperatives have a good perception of their environment and the effects that the latter has on the cooperative. It also emerges that cooperatives face a high degree of vulnerability in the current context. This vulnerability is due to several factors categorised into five main groups, namely organisational, economic, climatic, socio-cultural and relational factors. Finally, we note that in the face of these vulnerabilities and according to the perceptions of the actors, several strategic organisational and farming choices are made by the actors to ensure their survival.La présente thèse vise à comprendre les mécanismes par lesquelles les stratégies organisationnelles mises en œuvre par les acteurs agricoles favorisent l’adaptation des coopératives agricoles face aux effets des changements climatiques. Une démarche méthodologique essentiellement qualitative basée sur un positionnement interprétativiste et un mode de raisonnement inductif a été adoptés. Elle a consisté à mener des entretiens semi-directifs et focus group avec soixante-treize (73) acteurs de coopératives agricoles intervenant dans la production du coton, du maïs et du maraichage et avec les acteurs des structures d’accompagnement et d’encadrement de ces coopératives. Au terme des analyses, il ressort que les acteurs des coopératives agricoles ont une bonne perception de leur environnement et des effets que ce dernier provoque sur la coopérative. Aussi, il ressort que les coopératives font face à un degré élevé de vulnérabilité dans le contexte actuel. Cette vulnérabilité est due à plusieurs facteurs catégorisés en cinq grands groupes à savoir les facteurs organisationnels, économiques, climatiques, socioculturels et enfin les facteurs relationnels. Nous retenons enfin que face à ces vulnérabilités et en fonction des perceptions des acteurs, plusieurs choix stratégiques organisationnels et paysans sont opérés par les acteurs afin d’assurer leur survie
Vie professionnelle - vie privée des femmes dirigeantes au sein des organisations au Bénin
Full text linkCette recherche se veut une contribution à l’analyse des déterminants de la conciliation vie privée-vie professionnelle des femmes dirigeantes au sein des organisations en République du Bénin. Notre objectif est donc d’analyser l’influence de certaines variables de la vie professionnelle mises en évidence par la littérature sur la vie privée des femmes dirigeantes. En effet, il existe une littérature abondante principalement anglo-saxonne, sur ce sujet. Cependant, les résultats empiriques des études réalisées n’apportent pas encore une réponse définitive à la question de la conciliation vie privée-vie professionnelle de cette population de leader. Pour conduire cette étude, le modèle d’analyse du comportement social des organisations a été mobilisé. Les données de l’enquête portant sur 105 femmes dirigeantes ont permis la validation empirique du modèle. Les résultats montrent que les activités exercées, le temps consacré aux activités exercées et l’énergie déployée aux activités exercées par les femmes dirigeantes au sein des organisations en République du Bénin ont un effet négatif sur leur vie privée. Ils confirment ainsi l’effet de la vie professionnelle sur la vie privée des femmes dirigeantes au sein des organisations en République du Bénin
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
