    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

    Médecine (Rhumatologie)Les maladies musculo-squelettiques (MSQ) sont des maladies fréquentes qui se caractérisent par une faible mortalité mais un fort retentissement fonctionnel. Plusieurs études ont déjà montré la nécessité d’une meilleure prise en charge globale des MSQ pour améliorer la qualité de vie liée à la santé. L’objectif de cette étude était de quantifier le retentissement global des MSQ dans le monde et d’étudier leur évolution au cours des 15 dernières années, à partir de la base de données de l’Organisation Mondiale de la Santé (OMS). Nous avons extrait les données relatives au retentissement des MSQ, comparativement à 22 autres causes de morbidité à partir de la base mondiale « Global Burden of Disease » de l’OMS. Nous avons analysé les données de DALY (nombre d’années perdues liées à l’incapacité), YLD (années vécues avec un handicap) et YLL (années de vies perdues liées à l’incapacité) des MSQ comparativement à l’ensemble des autres pathologies pays par pays puis à l’échelle des continents et du monde. En 2015, les MSQ sont la 9e cause de DALYs (sur les 23 causes de morbidité définies par l’OMS), la 2e cause d’YLDs et la 19ème cause d’YLL dans le monde. L’Europe est le continent où la proportion de DALYs MSQ est la plus élevée par rapport à l’ensemble des causes des DALYs (médiane 6,66% [écart interquartile, EIQ: 5.30 – 7.88]) tandis que la proportion la plus faible est observée en Afrique (1,33% [EIQ: 1.03 – 1.92]). En France, les MSQ sont la 5e cause de DALYs (7,5% de la totalité des DALYs), la 2ème cause d’YLD (17,6%) et la 17ème cause d’YLL (0,5%) ce qui place la France à la 23/183ème place par importance de DALYs liés aux MSQ dans le monde. Les MSQ ont un taux de mortalité faible mais entrainent un retentissement important de par leur chronicité et l’altération de la qualité de vie qu’elles engendrent. En ce sens, les YLDs plutôt que les YLLs composent l’essentiel des DALYs musculo-squelettiques. Le retentissement des MSQ, évalué par les DALYs a progressé au cours des 15 dernières années suite au vieillissement global de la population mondiale, surtout dans les pays en voie de développement. L’Europe reste encore le continent où le retentissement des maladies MSQ est le plus important. Cette analyse détaillée de la base Global Burden Disease de l’OMS permet pour la première fois de préciser le retentissement global des maladies musculo-squelettiques, comparativement aux autres types de pathologies, à l’échelle de la France, des continents, et du monde. En 2015, les MSQ se placent à la 9e position des causes de DALYs dans le monde et à la 5ème place en FranceBackground: Musculoskeletal (MSK) diseases are expected to have a growing impact worldwide. Objective: To analyse the worldwide burden of MSK diseases from 2000 to 2015. Methods: Disability-adjusted life years (DALYs), which combines the years of life lost (YLLs) and the years lived with disability (YLDs), were extracted for 183 countries from the WHO Global Health Estimates Database. We analysed the median proportion of DALYS, YLLs and YLDs for MSK diseases (ICD-10: M00-M99) among the 23 WHO categories of diseases. Mixed models were built to assess temporal changes. Results: Worldwide, the total number of MSK DALYs increased significantly from 80,225,634.6 in 2000 to 107,885,832.6 in 2015 (p - 0.001), with the total number of MSK YLDs increasing from 77,377,709.4 to 103,817,908.4 (p = 0.0008) and MSK diseases being the second cause of YLDs worldwide. YLLs due to MSK diseases increased from 2,847,925.2 to 4,067,924.2 (p = 0.03). In 2015, the median proportion of DALYs attributed to MSK diseases was 6.66% (IQR: 5.30 - 7.88) in Europe versus 4.66% (3.98 - 5.59) in the Americas (p - 0.0001 vs Europe), 4.17% (3.14 - 6.25) in Asia (p - 0.0001), 4.14% (2.65 - 5.57) in Oceania (p = 0.0008) and 1.33% (1.03 - 1.92) in Africa (p - 0.0001). We observed a significant correlation (r = 0.85, p - 0.0001) between the proportion of MSK DALYs and the gross domestic product per capita for the year 2015. Conclusions: The burden of MSK diseases increased significantly between 2000 and 2015 and is high in Europe. These results are crucial to health professionals and policy makers to implement future health plan adjustments for MSK disease

    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

    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

    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.
