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

DHA supplementation and skeletal muscle of adult rat in hypoxia
No full textLe maintien ou le renforcement de la masse et de la fonction musculaire, altérées chez les patients BPCO, est un objectif primordial pour préserver, voire améliorer leur tolérance à l'effort, leur qualité de vie et leur survie. Afin d'optimiser la prise en charge de cette dysfonction musculaire, la réhabilitation est complétée par des interventions nutritionnelles, encore appelées réhabilitations nutritionnelles. Dans ce contexte, l'apport d'acides gras polyinsaturés de la série n-3, et plus particulièrement d'acide docosahexaénoïque (DHA), pourrait s'avérer intéressant en raison de leurs effets bénéfiques démontrés dans plusieurs pathologies chroniques. L'objectif de ce travail était donc de caractériser les effets d'une supplémentation en DHA sur la tolérance à l'effort et sur le métabolisme énergétique des muscles squelettiques de rats adultes exposés à une hypoxie comme modèle de muscle de patient BPCO au stade de l'insuffisance respiratoire chronique. La tolérance à l'effort est améliorée par le DHA, que les rats soient conditionnés en normoxie ou en hypoxie. En normoxie, les mécanismes impliqués seraient liés à un effet du DHA mimétique de celui d'un exercice d'endurance, avec une activation de l'AMPK et une amélioration de la fonction mitochondriale étudiée sur fibres musculaires perméabilisées. En hypoxie, le DHA agirait différemment, réduisant les effets de l'hypoxie sur le muscle, sans que les mécanismes mimétiques de l'exercice d'endurance ne soient clairement retrouvés. La prise de DHA chez des rats entrainés et conditionnés en hypoxie permet également un gain d'endurance mais les mécanismes à l'origine de cet effet ne sont pas élucidés et nécessitent des travaux complémentaires. Au vu des résultats sur le muscle, la supplémentation en DHA pourrait donc être bénéfique dans la prise en charge de la dysfonction musculaire dans les maladies chroniques telles que la BPCO.The maintenance and reinforcement of skeletal muscle mass and function, impaired in COPD patients, is a crucial aim to preserve, and even improve, their exercise tolerance, quality of life and survival. In order to optimize the management of such a muscular dysfunction, rehabilitation could be completed by nutritional interventions, also called nutritional rehabilitation. In this context, the intake of polyunsaturated fatty acids of the n-3 class, and particularly of docosahexaenoic acid (DHA), could be interesting, due to their benefic effects demonstrated in many chronic pathologies. Therefore, the aim of our work was to characterize the effects of DHA supplementation on exercise tolerance and skeletal muscle metabolism in rats exposed to hypoxia as a model of muscle dysfunction as seen in COPD patients suffering chronic respiratory failure. Results showed that exercise tolerance was improved by DHA in both normoxia and hypoxia conditions. In normoxia, the involved mechanisms may rely on an endurance exercise mimetic effect of DHA, including AMPK activation and improved mitochondrial function studied on permeabilized muscular fibers. In hypoxia, DHA acts differently, probably by minimizing hypoxia effects on muscle. However, the endurance exercise mimetic mechanisms were not clearly found. In hypoxia exposed-endurance trained-rats, DHA improved endurance exercise capacity but the involved mechanisms were not fully characterized and need further work. In conclusion, our results on muscle suggest that DHA supplementation could be beneficial in management of muscular dysfunction induced by chronic diseases such as COPD
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.
