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
Fibronectin type III domain-containing (FNDC) : facteurs clés dans le métabolisme énergétique et les fonctions ovariennes chez la vache ?
Full text linkThèse réalisée en cotutelle avec l’Université de Tours présentée en vue de l’obtention du grade de Philosophiae doctor (Ph.D.) en sciences vétérinaires option Reproduction et Philosophiae doctor (Ph.D.) en Sciences de la vie et de la SantéLa sélection génétique pour la production laitière a induit une diminution de la fertilité de la vache laitière. Au début de la lactation, les besoins énergétiques dépassent la consommation d’énergie et la vache rentre en bilan énergétique négatif (BEN). Cela induit une mobilisation du tissu adipeux, suivi, en cas de fort BEN d’une mobilisation du muscle squelettique. Les tissus adipeux et musculaire sécrètent des adipokines et des myokines, respectivement, connues pour réguler les fonctions du follicule ovarien. Plus récemment, une famille d’adipokine-myokine a été caractérisée : Fibronectin type III domain-containing (FNDC). Cependant, le rôle de cette nouvelle famille dans le BEN et la fertilité n'avait, à ce jour, pas été étudié. L’hypothèse générale de cette thèse est que les FNDCs altèrent les fonctions ovariennes. Nous avons démontré ici que l’expression génique de FNDC3A, FNDC3B, FNDC4 et FNDC5 dans le tissu adipeux était augmentée une semaine post-partum. Uniquement les concentrations plasmatiques de FNDC5/irisine étaient augmentées durant cette période et l’ajout d’irisine à des explants de tissu adipeux in vitro a augmenté la sécrétion de glycérol et l’expression génique de l’ATGL et de la LHS suggérant le rôle de l’irisine dans la lipolyse. Les FNDCs sont présents dans l’ovaire et l’injection d'irisine et de FNDC4 directement dans un follicule ovarien en croissance in vivo a provoqué une régression folliculaire. In vitro, l'irisine a modulé le métabolisme du glucose des cellules de la granulosa et de la thèque et altéré la stéroïdogenèse tandis que FNDC4 a augmenté le métabolisme du glucose des cellules de la granulosa et a modulé le métabolisme des acides gras des cellules de la granulosa et de la thèque bovines de manière insulino-dépendante. Enfin, FNDC3A a réduit la glycolyse et la sécrétion de progestérone IGF1-dépendante des cellules de granulosa. Ainsi, ces données indiquent que les FNDCs pourraient réguler la folliculogenèse en modulant la stéroïdogenèse et le métabolisme du glucose.Genetic selection for dairy production has led to a decrease of dairy cows’ fertility. At the beginning of the lactation, energy needs exceed energy consumption, and the cow enters a negative energy balance (BEN). This induces a mobilization of adipose tissue, followed, in case of high BEN, by a mobilization of skeletal muscle. Adipose and muscle tissues secrete adipokines and myokines, respectively, known to regulate ovarian follicle functions. More recently, a family of adipokine-myokine has been characterized: Fibronectin type III domain-containing (FNDC). However, the role of this new family in BEN and fertility has not been studied to date. The general hypothesis of this thesis is that FDNCs affect ovarian function. We demonstrated herein that the gene expression of FNDC3A, FNDC3B, FNDC4 and FNDC5 in adipose tissue was increased one week postpartum. Only plasma concentrations of FNDC5/irisin were increased during this period and the addition of irisin to adipose tissue explants in vitro increased glycerol secretion and gene expression of ATGL and LHS suggesting the role of irisin in lipolysis. The FNDCs are present in the ovary and injection of irisin and FNDC4 directly into a growing ovarian follicle in vivo caused follicular regression. In vitro, irisin modulated glucose metabolism of granulosa and theca cells and impaired steroidogenesis in vitro while FNDC4 increased glucose metabolism of granulosa cells and modulated fatty acid metabolism of granulosa and theca cells in an insulin-dependent manner. Finally, the addition of recombinant FNDC3A reduced glycolysis and IGF1-dependent progesterone secretion of granulosa cells. Taken together, these data suggest that FNDCs regulate folliculogenesis by modulating ovarian steroidogenesis and glucose metabolism
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

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.
