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

Modélisation du procédé de fabrication des batteries lithium-ion : impact de la mésostructure de l'électrode sur sa performance électrochimique
No full textThis Ph.D. project is within the scope of the ERC-ARTISTIC Project, which aims to correlate the fabrication process to the performance of lithium-ion batteries. To do so, the mesostructure of the electrode is either simulated with a 3-D physical model in accordance with the different fabrication parameters used, either stochastically generated, or reconstructed from tomography data. The mesostructure is imported and the partial differential equations are solved in Comsol Multiphysics, which relies on the finite element method. This Ph.D. investigations aim to unravel the link between structural observables and the performance of an electrode. The novelty of this study relies on the explicit consideration of the inactive phase of the electrode, as well as the investigations on the interphase that forms at the interface between the active material and the electrolyte.Several algorithms were developed during the course of this Ph.D. to address the obstacles to include the carbon binder phase explicitly in a 3-D electrochemical model. In particular, a stochastic generation functionality allowing a fine tuning over the electrode through the particle size distribution and shape, and the inactive phase morphology and a meshing algorithm enabling the meshing of an indefinite number of phase and saving into a format suitable to be imported into Comsol Multiphysics. All these tools were embedded into a single graphical user interface to increase their user-friendliness. Fine studies on the role of the inactive phase and its location were carried out, highlighting the importance of the explicit consideration of this phase. A particular focus was put on the calendering step and its impact on the mesostructure and the electrochemical performance to unravel the link between the properties of the mesostructure and the electrochemical behavior of a cell. Moreover, we investigated the impact of a heterogeneous layer arising from electrolyte decomposition at both the positive and negative electrodes, i.e. the cathode and solid electrolyte interphase. Finally, a full-cell model demonstrates the relevance of all the tools developed and presented in this work to achieve state-of-the-art studies. Indeed, a discharge of a full-cell with each particle individually identified in both electrodes illustrates the capability of the algorithms to allow fine investigations with the observables of each particles individually accessibleCe projet de thèse s'inscrit dans le projet ERC ARTISTIC dont l'objectif est de développer une plateforme de simulation prédictive des procédés de fabrication des électrodes de batterie lithium ion. Cette thèse consiste à développer un simulateur dynamique avec résolution spatiale 3D de la performance électrochimique des électrodes de batterie lithium ion. Ce simulateur utilise des électrodes issues de simulations physiques, de générations stochastiques ou bien d'images tomographiques, et repose sur la méthode d'éléments finis dans le logiciel Comsol Multiphysics. L'ensemble des travaux a pour objectif d'établir des liens entre des observables de la mésostructure d'une électrode à ses performances électrochimiques. L'apport de cette thèse vis-à-vis de l'état de l’art consiste en la considération explicite de la phase carbone et binder au sein du système modélisé, ainsi qu'en l'étude de l'interphase se formant à l'interface entre le matériau actif et l'électrolyte. Plusieurs algorithmes ont été développés au cours de cette thèse pour répondre aux problématiques qui se posent lors de l'inclusion de manière explicite de la phase inactive dans un modèle électrochimique 3-D. En particulier une fonctionnalité permettant la génération stochastique d'électrodes avec un fin contrôle sur ses paramètres tels que la distribution de taille ou la morphologie des particules actives et la morphologie du domaine carbone et binder, ainsi qu'un algorithme permettant le maillage d'un nombre indéfini de phase ainsi que la sauvegarde du maillage en un format favorisant l'importation dans le logiciel Comsol Multiphysics. Toutes ces fonctionnalités ont été inclues dans une seule interface graphique afin de rendre leur utilisation plus intuitive. Enfin, des études portant sur le rôle de la phase inactive et l'impact de son emplacement sur la comportement d'une électrode en décharge ont été menées, ainsi que des travaux sur l'impact de certaines propriétés de la mésostructure sur la performance d'une batterie. L'interface solide électrolyte résultant de la décomposition de l'électrolyte a également été étudiée pour des matériaux actifs d'électrodes négatives et positives. Pour conclure, un modèle de batterie complète est présenté et démontre la pertinence des outils développés et présentés dans ce manuscrit pour réaliser des simulations au niveau voire au-delà de l'état-de-l'art. En effet, ce modèle est illustré à travers la décharge d'une batterie complète avec toutes les particules de matériaux actifs individuellement identifiés, ce qui permet donc d'avoir accès individuellement à leurs observables et de ce fait avoir un suivi plus fin de l'évolution de la batterie en fonctionnemen
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.
