    Going Beyond Counting First Authors in Author Co-citation Analysis

    Full text link
    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

    Full text link
    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

    Full text link
    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

    Système de gestion pour la pérennisation de la filière crabe de mangrove Scylla serrata (Forskal, 1775) : cas de Boanamary à Madagascar

    Full text link
    Le crabe Scylla serrata est l’habitant le plus intéressant de l’écosystème de mangrove. La préservation et la restauration des mangroves constituent un moyen de pérenniser l’exploitation des crabes. Malheureusement, certaines mangroves localisées à proximité des grandes villes exposent des signes de surexploitation notamment la baisse du rendement de pêche et la disparition des gros crabes. Une forte pression a été constatée par l’augmentation de la demande des crabes vivants à l’exportation, la croissance démographique et la migration vers la côte. Comment les pêcheurs peuvent-ils gagner plus tout en capturant moins ? L’objectif de l’étude est d’assurer la pérennisation de la filière crabe de mangrove par une gestion durable et une exploitation raisonnable. A Boanamary, l’analyse statistique sur les échantillons de nombre des individus mâles et femelles capturés a été réalisée depuis la pêche jusqu’à la commercialisation.  Les crabes capturés ont été mesurés à partir d’un pied à coulisses et pesés par une balance alimentaire. La vulgarisation des pratiques novatrices des matériels innovants comme la pêche à la nasse (treko) respectant une maille stricte a été adoptée et utilisée pour éviter la capture des crabes inférieure à 11 cm. Le renforcement de la réglementation de fermeture de 2 mois, les systèmes de contrôle, de suivi et de surveillance communautaires intégrés permettent une meilleure gestion de la pérennisation de la filière. Ainsi, les résultats obtenus montrent une réduction de pertes après capture de 15% pendant l’exploitation de la chaine de valeur des crabes. Par ailleurs, la taille céphalothoracique des crabes capturé présente un intervalle de 10 à 13 cm n'atteignant plus le gros calibre qui devrait être supérieur à 15 cm. La taille moyenne des crabes capturés mesure 12 cm. Les pêcheurs de Boanamary présentent 90% de la population. Leurs revenues dépendent de la pêche. La gestion de la chaîne de valeur depuis la pêche jusqu’à la commercialisation, en respectant la règlementation mise en vigueur, demeure primordiale pour la durabilité de la filière crabe et procure un bénéfice social et économique des habitants et même du pays. / The crab Scylla serrata is the most interesting inhabitant of the mangrove ecosystem. The preservation and restoration of mangroves is a way to sustain the exploitation of crabs. Unfortunately, some mangroves located near major cities show signs of overexploitation, including the decline in fishing yield and the disappearance of large crabs. Strong pressure has been seen from increased demand for live crabs for export, population growth and migration to the coast. How can fishermen earn more while catching less? The objective of the study is to ensure the sustainability of the mangrove crab sector through sustainable management and reasonable exploitation. In Boanamary, statistical analysis of the samples of the number of male and female individuals caught was carried out from fishing to marketing. The crabs caught were measured from a caliper and weighed by a food scale. The popularization of innovative practices and innovative equipment such as trap fishing (treko) respecting a strict mesh size has been adopted and used to avoid the capture of crabs smaller than 11 cm. The strengthening of the 2-month closure regulations, the integrated Community control, monitoring and surveillance systems allow for better management of the sustainability of the sector. Thus, the results obtained show a 15% reduction in post-harvest losses during the exploitation of the crab value chain. In addition, the cephalothoracic size of the crabs caught has an interval of 10 to 13 cm, no longer reaching the large calibre, which should be greater than 15 cm. The average size of the crabs caught is 12 cm. The fishermen of Boanamary represent 90% of the population. Their income depends on fishing. The management of the value chain from fishing to marketing, in compliance with the regulations in force, remains essential for the sustainability of the crab sector and provides social and economic benefits to the inhabitants and even to the country

    koamabayili/VECTRON-author-checklist: VECTRON author checklist

    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

    Author Under Sail The Imagination of Jack London, 1893-1902

    No full text
    In Author Under Sail, Jay Williams offers the first complete literary biography of Jack London as a professional writer engaged in the labor of writing. It examines the authorial imagination in London's work, the use of imagination in both his fiction and nonfiction, and the ways he defined imagination in the creative process in his business dealings with his publishers, editors, and agents. In this first volume of a two-volume biography, Williams traverses the years 1893 to 1902, from London's "Story of a Typhoon" to The People of the Abyss. The Jack London who emerges in the pages of Author Under Sail is a writer whose partnership with publishers, most notably his productive alliance with George Brett of Macmillan, was one of the most formative in American literary history. London pioneered many author models during the heyday of realism and naturalism, blurring the boundaries of these popular genres by focusing on absorption and theatricality and the representation of the seen and unseen. London created an impassioned, sincere, and extremely personal realism unlike that of other American writers of the time. Author Under Sail is a literary tour de force that reveals the full range of London as writer, creative citizen, and entrepreneur at the same time it sheds light on the maverick side of machine-age literature.Intro -- Title Page -- Copyright Page -- Dedication -- Contents -- Acknowledgments -- Introduction -- 1.
