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
Digital financial innovation, migration and development in sub-Saharan Africa
No full textCette thèse examine la manière dont les innovations financières digitales telles que les plateformes de financement participatif et le mobile money influencent les comportements des migrants en matière de transfert de fonds individuels et collectifs, ainsi que leur impact sur le développement économique en Afrique sub-saharienne. L’Afrique sub-saharienne connaît une croissance rapide en matière d’adoption des technologies financières, souvent en réponse à l’inaccessibilité des services bancaires traditionnels. Parallèlement, les migrations internationales, tant intra-africaines qu’intercontinentales, jouent un rôle crucial dans les dynamiques économiques de la région, notamment par les transferts de fonds des migrants. Ce travail de recherche s’articule autour de trois articles distincts et adopte une approche mixte combinant une analyse quantitative et qualitative. Le premier chapitre révèle que les individus qui possèdent et utilisent un compte mobile money sont moins susceptibles d’envoyer des fonds par un canal informel de transfert (Amis, famille, courrier, Hawala. . . ). La décomposition des pays par quartile d’index de niveau de développement financier montre que l’impact négatif du mobile money sur le recours aux canaux informels est plus prononcé dans des pays caractérisés par un système financier insuffisamment développé. Le second chapitre met en évidence l’existence d’une relation positive entre l’utilisation du mobile money et la mise en place d’une activité génératrice de revenu non agricole. Cette relation passe par le canal des transferts des fonds et est fonction de la fréquence de réception de ces transferts. Plus précisément, le mobile money accroit la probabilité de recevoir des transferts de fonds. Cependant, les individus qui reçoivent régulièrement des transferts de fonds ont une plus faible probabilité de créer une activité génératrice de revenu non agricole que ceux qui en reçoivent moins fréquemment. Le troisième chapitre s’intéresse aux plateformes de crowdfunding de micro-crédit et à la perception qu’ont les Organisations de Solidarité Internationales des Migrants (OSIM) maliens concernant leur développement. L’analyse thématique montre que les OSIM ne considèrent pas les plateformes comme une menace pour la survie de leur activité de financement entrepreneurial et de développement local. Les deux acteurs ont des points communs et complémentaires qui pourraient permettre de mieux servir les populations cibles dans les pays en développement. Les technologies des plateformes de crowdfunding de microcrédit pourraient permettre un déploiement optimal de la philanthropie des OSIM et, à son tour, la diaspora via les OSIM pourraient proposer des réseaux et des connaissances qui peuvent compenser les vulnérabilités des plateformes de crowdfunding de microcrédit. Les résultats de cette recherche éclairent les mécanismes par lesquels les innovations financières digitales facilitent les transferts de fonds et renforcent leur impact sur le développement en Afrique sub -saharienne. Les implications pour les politiques publiques sont explorées, mettant en lumière l’importance de promouvoir l’inclusion financière à travers des technologies accessibles, abordables, fiables et efficaces pour un développement durable.This thesis examines how digital financial innovations such as crowdfunding platforms and mobile money influence migrants’ individual and collective remittance behaviour and their impact on economic development in sub-Saharan Africa. Sub-Saharan Africa is experiencing rapid growth in the adoption of financial technologies, often in response to the inaccessibility of traditional banking services. At the same time, international migration, both intra-African and intercontinental, is playing a crucial role in the region’s economic dynamics, particularly through migrant remittances. This research is structured around three articles and adopts a mixed approach combining quantitative and qualitative analysis. The first chapter reveals that individuals who own and use a mobile money account are less likely to send funds via an informal transfer channel (friends, family, mail, Hawala, etc.). The breakdown of countries by financial development index quartile shows that the negative impact of mobile money on the use of informal channels is more pronounced in countries with an underdeveloped financial system. The second chapter highlights a positive relationship between using mobile money and establishing a non-agricultural income generating activity. The remittance channel mediates this relationship and is a function of the frequency with which remittances are received. More specifically, mobile money increases the probability of receiving remittances. However, individuals who receive remittances regularly have a lower probability of creating a non-farm income-generating activity than those who receive them less frequently. The third chapter looks at microcredit crowdfunding platforms
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
