Santé et croissance économique dans les pays de l’union économique et monétaire ouest africain (UEMOA)
Full text linkLe pays le plus avancé de l’UEMOA a l’espérance de vie la plus faible. Problématique Dans un contexte où pratiquement tous des pays de l’UEMOA, mettent en place des programmes de couverture sanitaire universelle, la question de l’effet de la santé sur la croissance économique se pose. La littérature économique considère le capital humain comme un des facteurs pouvant expliquer le miracle asiatique, comparé à l’échec du développement dans la grande majorité des pays africains durant les années..
ANALYSE DES EFFETS DES TECHNOLOGIES DE L’INFORMATION ET DE LA COMMUNICATION (TIC) SUR L’EMPLOI AU SENEGAL
Full text linkCet article analyse les effets des TIC sur l’emploi au Sénégal. Le papier utilise des données d’enquête sur les entreprises, réalisée uniquement dans le but d’étudier les effets des TIC sur le marché du travail. La modélisation économétrique porte sur les facteurs qui expliquent directement ou indirectement les flux d’emplois pour les différentes catégories socioprofessionnelles à partir d’un modèle Tobit de type I. Il ressort des résultats que les TIC ont eu des effets positifs sur le niveau global de l’emploi et de façon spécifique sur l’emploi féminin. L’analyse des effets des TIC sur les flux d’emplois des différentes catégories socioprofessionnelles a montré que la diffusion des TIC au sein des entreprises, s’accompagne de changements dans la qualification exigée des employeurs mais aussi des changements dans leurs organisations. Les résultats ont aussi montré que : les TIC contribuent également à faire émerger un grand nombre d’emplois peu qualifiés, surtout féminins, notamment dans les services, ainsi que dans les activités commerciales. Cependant elles contribuent concomitamment à l’instabilité de tous les emplois qualifiés et non qualifiés. En définitive, Cet article montre que l’adoption des TIC par les entreprises ne conduit pas à un chômage structurel généralisé mais suscite plutôt une évolution continuelle de la nature des emplois et une hausse correspondante des exigences professionnelles liées à des types d’emplois donnés

Perception of Climate Change Impacts on Livelihoods in Central Mali
Full text linkThe main objective of this research is to analyze the perceptions of local communities on climate change and its impacts on livelihoods in Central Mali. A survey data collected using multistage random sampling methods have been used for that purpose. From the result, the multinomial logit analysis, shows that households in Central Mali are well aware of climate change, its different manifestations (change in temperature, in precipitation duration and amount, in wind etc.) and the related adverse effects on their livelihoods. However, they face considerable challenges in adapting to those changes in climate. Lack of funds and credit facilities, lack of access to timely weather information, lack of technologies (physical infrastructure, technical material and equipment), lack of knowledge regarding adaptation technics (required human skills, e.g., applying specific planning and management approaches and methods), lack of appropriate seeds have been identified as the major critical barriers to climate change adaptation in the region. These constraints probably explain why individuals often resort to poor but more affordable adaptation strategies which are conflict sensitive and likely to disrupt social cohesion between local communities. In this context, implementing policies aiming at improving the effectiveness of extension services in supporting households to better adapt to climate change could be of great importance
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
