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
The role of drug depots in the informal circulation of medicines in Madagascar
Get PDFThe geographical circulation of products used in a therapeutic context at different spatial scales is a phenomenon that has been increasing for several decades with the progression of trade, ease of travel, migration and the spread of biomedicine on a global scale. Health products are now part of economic globalisation and represent a lucrative market that is difficult to quantify due to the formal and informal channels and networks used. The ci..
Le marché informel du médicament à Madagascar : une revanche populaire
No full textThis work shows us, in an inductive way, how the informal drug market is a popular revenge. This notion of "popular revenge" is understood as a form of counter-power put in place by drug sellers, and whose practice is made sustainable by the popular demand for pharmaceutical drugs. The informal drug market, as an example of a popular economy initiative, embodies a phenomenon of counter-power whose strength is to propose an alternative to the pharmaceutical structural framework in place in Madagascar, considered by our interlocutors as failing and not adequate to the demands of users. This counter-power is organized around the drug as "merchandise" and puts its market value on its therapeutic value. On the one hand, the trade of this commodity offers to its sellers exercising within the informal sector the opportunity of an escape from the peasant condition and the invention of a new "living together", based on ancestral values: the fihavanana or the principle of unity which constitutes the keystone of the social relations in Madagascar, and the respect of tanindrazana, the ancestral lands. On the other hand, for users, the acquisition of "drug-goods", as permitted through the informal drug market and carried out outside the biomedical context of the medical consultation, is in line with usual spending patterns.

Le rôle des dépôts de médicaments dans la circulation informelle de médicaments à Madagascar
Get PDFRésumé : Le présent article rend compte du rôle des dépôts de médicaments dans l’approvisionnement du secteur pharmaceutique informel à Madagascar. Les dépôts constituent un acteur incontournable dans la distribution pharmaceutique à Madagascar, ils ont été mis en place en 2011 pour pallier le manque de pharmaciens sur l’île ainsi que pour répondre aux problèmes d’accessibilités des populations aux médicaments essentiels. Partant de l’analyse de l’organisation de la distribution de médicaments à Madagascar (secteur privé, public et informel), nous y décrivons les caractéristiques, mécanismes de fonctionnement et modalités d’approvisionnement des dépôts de médicaments. Cet article se base sur les résultats de ma thèse, dont les données ont été collectées par trois biais : entretiens semi-directifs, observations directes et relevés des points de ventes informels. Une centaine d’entretiens semi-directifs a été réalisé entre 2013 et 2017 à Madagascar auprès d’acteurs issus des différents secteurs de distribution pharmaceutique
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
