    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

    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

    Development of an alternative design method for aluminium open cross-sections using the Overall Interaction Concept

    L'utilisation accrue de l'aluminium structural au cours des dernières décennies s'explique par ses nombreux avantages, tels que son excellente résistance par rapport à son poids, sa résistance à la corrosion et ses bénéfices environnementaux. Dû à son coup initial élevé, l'optimisation des méthodes de conception est essentielle pour exploiter pleinement ces propriétés. Cependant, les normes actuelles utilisent des approches simplifiées pour prédire la résistance des éléments en aluminium, qui ne sont pas optimisées pour tenir compte des effets de l'écrouissage, des instabilités, des propriétés réduites dans la zone affectée thermiquement et des formes extrudées souvent complexes. Ce mémoire présente le développement d'une méthode alternative de dimensionnement des sections ouvertes en aluminium, basée sur l'Overall Interaction Concept (O.I.C.). Cette approche de conception innovante est basée sur l'interaction entre résistance et stabilité, tout en considérant les imperfections géométriques et matérielles. De plus, elle permet d'obtenir des résultats précis et cohérents par l'utilisation de courbes de flambement continues. Un modèle numérique d'éléments finis a été développé pour prédire avec précision la résistance en section des éléments en aluminium. Son efficacité a été validée en comparant les résultats à ceux de tests expérimentaux. Des études paramétriques approfondies ont ensuite été menées, permettant d'étudier l'impact de diverses géométries, d'alliages et de cas de charge sur la résistance. Avec les résultats de plus de 4500 simulations numériques non linéaires, des propositions de calculs de type O.I.C. ont été formulées pour la résistance locale des sections d'aluminium extrudées et soudées en forme de "I". La performance des propositions a été évaluée en la comparant d'abord aux résultats numériques, puis aux prévisions de résistance des normes de conception d'aluminium canadienne, européenne et américaine. Les comparaisons ont prouvé que la méthode de conception de l'O.I.C. mène à des résultats beaucoup plus précis que les normes actuelles, tout en étant plus simple et plus efficace.The increased use of structural aluminium in the last decades can be explained by the many advantages of this material, such as its great strength-to-weight ratio, resistance to corrosion, and environmental benefits. Due to its high initial cost, optimization of design methods is essential to fully benefit of these properties. However, current standards use simplified approaches to predict the resistance of aluminium elements, that are not optimized to account for the effects of strain hardening, instabilities, heat reduced properties and often complex extruded shapes. This thesis presents the investigations conducted for the development of an alternative design method for aluminium open cross-sections, based on the Overall Interaction Concept (O.I.C.). This innovative design approach relies on the interaction between resistance and stability, and also allows to consider geometrical and material imperfections. Moreover, it allows to obtain precise and consistent results by the use of continuous buckling curves. A numerical finite element model was developed to accurately predict the cross-sectional resistance of aluminium elements. Its efficiency was validated by comparing the results to available experimental test data. Extensive parametric studies were then conducted, allowing to study the impact of various geometries, alloys, and load cases on the resistance. Using the results from more than 4500 nonlinear numerical simulations, O.I.C.-type design proposals were formulated for the local resistance of extruded and welded aluminium sections of "I" shape. The performance of the proposals was evaluated by first comparing it to the numerical results, then to the resistance predictions from the Canadian, European, and American aluminium design standards. The comparisons showed that the O.I.C. design proposal leads to much more accurate results than the current standards, while still being simpler and more efficient

    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

    koamabayili/VECTRON-author-checklist: VECTRON author checklist

    No full text
    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.
