    Going Beyond Counting First Authors in Author Co-citation Analysis

    The 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

    “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

    We 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

    We 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

    We 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

    Dynamique urbaine et problemes environementaux à Ougadougou, Burkina Faso

    Le Burkina Faso connaît une urbanisation relativement modérée. En effet, selon le recensement de décembre 1985, le taux d'urbanisation s'élevait à 13,6% et cela en tenant compte des seize centres secondaires de plus de 10.000 habitants. En se basant sur les 119 localités de plus de 5.000 habitants, ce taux dépasse à peine 27%. Or des pays tels que la Côte d'Ivoire, le Ghana et le Sénégal présentaient au même moment des taux de 45 à 50%. Cependant la taille et le nombre des centres urbains ne cessent de croître. Mais jusqu'à présent, le pays ne compte que deux principales villes: Ouagadougou et Bobo Dioulasso avec respectivement 441.514 et 228.668 habitants soit 70% environ de la population urbaine nationale. Les estimations de 1992 donnent à Ouagadougou 842.000 habitants et environ 400.000 à Bobo-Dioulasso. Ouagadougou, la capitale est sans doute le pôle le plus développé avec une armature urbaine assez complète, des activités et des fonctions diversifiées. Le développement urbain est ici plus perceptible qu'ailleurs, il en est autant des problèmes: équipements insuffisants et inadaptés, marginalisation des populations démunies, destruction du patrimoine naturel, forte croissance démographique. Les problèmes environnementaux sont multiples et se manifestent différemment avec plus ou moins d'acuité. C'est cet aspect précis que nous allons analyser

    Enclavement et industrialisation au Burkina Faso

    Enclavement and Industrialization in Burkina Faso .The phenomenon of the enclavement of Burkina Faso has various implications on the process of industrialization that is being carried out in the country. The geographic position of the nation has some advantages (a country of transit, an important crossroads of exchanges in the West Africain zone, etc.), but which do not efface the vast distances that must be covered. On account of these handicaps, local industry typical of land-locked countries has come into being. It is an industry but slightly diversified and mainly located in the larger towns and cities. Because of this fact, and in spite of countless potential industrial possibilities, few of the country’s natural resources have been exploited. However, efforts are presently being undertaken to reinforce the basic infrastructures, especially transportation and communications, in order to achieve a certain coherence as respects the development programs under way.Le phénomène de l’enclavement du Burkina Faso a de nombreuses implications dans le processus d’industrialisation en cours. La situation géographique du pays présente quelques atouts (pays de transit, important carrefour d’échanges de la région ouest-africaine, etc.), qui n’effacent cependant pas les effets des grandes distances à parcourir. De ces contraintes sont nées des localisations industrielles typiques des pays sans débouché vers la mer : une industrie peu diversifiée essentiellement cantonnée dans les principales villes. De ce fait, malgré l’existence de nombreuses potentialités industrielles, peu de ressources ont été exploitées. Cependant, des efforts sont en train d’être déployés pour le renforcement des infrastructures de base, notamment des transports et communications, afin d’arriver à une certaine cohérence dans les actions de développement.Compaore Georges.
