Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe 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
Full text link“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 linkWe 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 linkWe 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

Five Essays on Cooperative Oligopoly Games
No full textTout d'abord, nous traitons des jeux d'oligopole de Cournot sous forme caractéristique gamma. Nous montrons que ces jeux sont balancés lorsque les fonctions de profit individuel sont concave. Ensuite, lorsque les fonctions de coût individuel sont linéaires, la «valeur au prorata de Nash» appartient au cœur. Par la suite, nous étudions les jeux d'oligopole de Cournot sous forme d'intervalle gamma. Nous prouvons que le cœur intervalle (standard) est non-vide si et seulement si le jeu d'oligopole de Cournot sous forme caractéristique gamma associé à la meilleure (plus faible) capacité qu'obtient chaque coalition admet un cœur non vide. Ensuite, nous analysons les jeux d'oligopole de Stackelberg sous forme caractéristique gamma. Nous montrons que le cœur est égal à l'ensemble des imputations. Ensuite, nous donnons une condition nécessaire et suffisante, qui dépend de l'hétérogénéité des coûts marginaux, assurant la non-vacuité du cœur. Enfin, nous considérons les jeux d'oligopole de Bertrand. Nous prouvons que les jeux sous les formes caractéristiques alpha ou bêta satisfont à la propriété de convexité. Ensuite, nous prouvons que la valeur de partage égalitaire appartient au cœur des jeux sous forme caractéristique gamma et nous donnons une condition suffisante qui assure que ces jeux satisfont à la propriété de convexité. Nous prolongeons cette analyse en supposant que les coûts marginaux sont distincts. Si la constante de la demande est suffisamment petite, alors les jeux sous forme caractéristique bêta satisfont à la propriété de balancement total. Autrement, ces jeux satisfont à la propriété de convexité.In the first essay, we study Cournot oligopoly TU-games in gamma-characteristic function form. First, we prove that if any individual profit function is concave, such games are balanced. Then, when the individual cost functions are linear, we provide a solution in the core, called NP(Nash Prorata) value. The second essay considers Cournot oligopoly interval game in gamma-set function form. The first (second) result states that the interval (standard) core is non empty if and only if the Cournot oligopoly TU-game associated with the best (worst) worth of every coalition in its worth interval admits a non-empty core. In the thirdessay, we focus on Stackelberg oligopoly TU-games in gamma-characteristic function form. First, we prove that the core is equal to the set of imputations. Th en, we provide a necessary and sufficient condition, depending on the heterogeneity of firms' marginal costs, under which the core is non-empty. In the fourth essay, we show that Bertrand oligopoly TU-games inalpha and beta-characteristic function forms are convex. Then, we prove that the equal division solution is in the core of Bertrand oligopoly TU-games in gamma-characteristic function form and we give a sufficient condition under which such games are convex. The fifth essay studies the case where the marginal costs are distinct. If the intercept of demand is sufficiently small then games in _beta-characteristic function form are totally balanced. Otherwise, these games are convex
Author Under Sail The Imagination of Jack London, 1893-1902
No full textIn 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.
