    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

    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

    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

    Simulation of phi 4 theory in the strong coupling expansion beyond the Ising Limit

    Diese Arbeit beschäftigt sich mit der Simulation der phi**4-Theorie mit dem Wurm-Algorithmus, einer Simulationsmethode die sich als sehr effizient bei der Betrachtung kritischer Systeme gezeigt hat. Die Entwicklung der Theorie in die Strong-Coupling-Expansion wird beschrieben und zwei Varianten des Wurm-Algorithmus werden vorgestellt. Eine Implementierung des Algorithmus in C wird angefertigt und die Ergebnisse von Tests im Ising- und Gauß-Limes sowie in phi**4-Theorie mit endlicher Wechselwirkung werden präsentiert und mit einer konventionellen Metropolis-Simulation verglichen. Anschließend wird die Dynamik des Algorithmus ausführlich im freien sowie im wechselwirkenden Fall der Theorie in zwei, drei und vier Dimensionen untersucht. In der freien zweidimensionalen Theorie weist der Algorithmus ausgeprägtes Critical Slowing Down mit kritischen Exponenten von bis zu 1.6 auf. In drei Dimensionen liegen alle kritischen Exponenten unter 1.0, und in vier Dimensionen messen wir kritische Exponenten von bis zu 0.6. Wir präsentieren eine Heuristik, die dieses Verhalten auf lange Autokorrelationen in der Besetzung des Link-Feldes zurückführt. Unsere Messungen in der wechselwirkenden Theorie werden bei lambda=0.5 durchgeführt. Autokorrelationszeiten sind hier wesentlich kürzer als in der freien Theorie. Kritische Exponenten sind von Observable zu Observable sehr unterschiedlich, liegen aber in jedem Fall unter 0.55. In vielen Fällen wird auch ein ein logarithmischer Zusammenhang festgestellt. Ein Methode zur Schätzung der renormierten Kopplung mit dem Wurm-Algorithmus wird vorgestellt. Tests zeigen jedoch, dass sich dieser Ansatz nicht für kritische Systeme eignet.This thesis reports on the simulation of phi**4 theory using the worm algorithm, a recent simulation method which has been proven to eliminate critical slowing down in a number of statistical systems. The untruncated strong coupling represention of the theory is derived and two variants of the worm algorithm for phi**4 theory are presented. The algorithm is implemented in C, and we report on tests in the Ising and Gaussian limits of the theory as well as at finite coupling strengths, and compare results with a standard Metropolis simulation. The dynamical behavior of the algorithm is examined in detail in the Gaussian case and in the interacting case at lambda=0.5 in two, three and four dimensions. We find substantial critical slowing down in the two-dimensional Gaussian case and measure critical exponents of up to 1.6. This is reduced in three dimensions where we measure critical exponents below one, and further reduced in four dimensions where critical exponents are below 0.6. We present some heuristic arguments that this is due to very long autocorrelations in the population of the link field. In the interacting theory, we find short autocorrelations independent of the dimension of the theory. Different observables here show distinct dynamical behavior, but all measured critical exponents are below 0.55. In several cases we also find logarithmic behavior. An approach to the estimation of the renormalized coupling using the worm algorithm is presented, but tests show that it is ill-suited for critical systems

    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.
