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

Contribution à la méthode de Mahler : équations linéaires et automates finis
No full textIn this thesis, we investigate topics belonging to number theory, and especially to transcendental number theory. We discuss the results we have obtained in the papers [13, 14, 15, 16]. Our main aim is to study the transcendence and algebraic independence of the values, at algebraic points, of the so-called Mahler functions. The latter are convergent power series satisfying difference equations for the operator z → z^q. In order to study these power series, we develop what is known as Mahler's method, a method initiated by Mahler in the late 1920's. Besides its theoretical interest, Mahler's method has applications regarding the complexity of expansions of real numbers in integer or algebraic bases. Indeed, Mahler functions whose coefficients belong to a finite set are precisely the generating series of automatic sequences. We broaden the scope of Mahler's method, completing the already well-advanced study of the transcendence and linear relations between q-Mahler functions evaluated at a given algebraic point. In particular, we prove a conjecture due to Cobham in 1968, stating that a Mahler function with rational coefficients cannot take algebraic irrational values at rational points. We also show that the algebraic relations between the values of q-Mahler functions at algebraic points all come from specializations of q-orbital functional relations, that is relations between these functions and their images under the iterated action of the map z → z^q. In addition, we establish an algorithm that allows us to determine whether or not an arbitrary Mahler function takes a transcendental value at a given algebraic point.In the second part of the thesis, we develop the theory of multivariate regular singular Mahler systems, a generic class of linear Mahler systems. We obtain a general criterion of algebraic independence for the values at algebraic points of Mahler functions associated with such systems. We could summarize this criterion in the following way: transcendental values of Mahler functions associated with operators having pairwise multiplicatively independent spectral radius, or with multiplicatively independent algebraic points, are always algebraically independent.Cette thèse se situe dans le domaine de la théorie des nombres. Nous y présentons les résultats obtenus dans [13, 14, 15, 16]. Nous étudions la transcendance et l'indépendance algébrique des valeurs de fonctions mahlériennes en des points algébriques. Ce sont des séries entières convergentes solutions d'équations linéaires aux différences pour l'opérateur z → z^q. Pour étudier ces fonctions, on utilise une méthode appelée méthode de Mahler, laquelle s'inscrit dans la grande famille des méthodes de transcendance. En plus d'un intérêt théorique important quant aux techniques de transcendance, la méthode de Mahler a des applications liées à la complexité du développement des nombres réels. En effet, les fonctions mahlériennes dont les coefficients appartiennent à un ensemble fini sont précisément les séries génératrices des suites automatiques.Nous élargissons le champ d'application de la méthode en parachevant l'étude, déjà bien entamée, de la transcendance des fonctions q-mahlériennes d'une variable, et des relations linéaires entre leurs valeurs, en un point algébrique. Nous démontrons notamment une conjecture de Cobham de 1968, énonçant le fait qu'une fonction mahlérienne à coefficients rationnels ne prend, aux points rationnels, que des valeurs rationnelles ou transcendantes. Nous montrons que les relations algébriques entre les valeurs de fonctions q-mahlériennes en un point algébrique proviennent, par spécialisation, d'une relation fonctionnelle q-orbitale, c'est-à-dire d'une relation entre ces fonctions et leurs images sous l'action répétée du morphisme z → z^q. Nous établissons également un algorithme permettant de déterminer si la valeur d'une fonction mahlérienne en un point algébrique donné est un nombre transcendant ou pas.Nous développons ensuite la théorie des systèmes mahlériens réguliers singuliers de plusieurs variables, une classe générique de systèmes mahlériens. Nous en déduisons un critère général d'indépendance algébrique pour les valeurs de fonctions mahlériennes associées à de tels systèmes. Ce critère pourrait être résumé de la façon suivante: des valeurs transcendantes de fonctions mahlériennes associées à des opérateurs ayant des rayons spectraux multiplicativement indépendants deux à deux, ou des points algébriques multiplicativement indépendants, sont toujours algébriquement indépendantes
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.
