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
Génie des produits formules (amélioration des spécifications de l'Ibuprofène, principe actif peu hydrosoluble, par le procédé d'atomisation)
No full textAvec les progrés opérés depuis quelques années dans le domaine de la synthèse chimique et les performances nouvelles générées, à la fois par la chimie combiantoire et les études de en plus sophistiquées de "screening" de molécules nouvelles, la Recherche et Développement Pharmaceutique se trouve très fréquemment confrontée à la formulation de principes actifs à très faible solubilité aqueuse et pour lesquels, cliniciens et services de marketing souhaitent mettre au point et commercialiser des formes solides pour administration par voie orale. Dans le contexte de la gestion de la qualité pharmaceutique, cette problématique oblige le formulateur à concevoir des formules et/ou proposer de nouveaux procédés de mise en forme. Ainsi, et pour un composant actif donné, les études de pré-formulation, essentiellement basées sur la sélectionqualitative d'excipients fonctionnels, puis les études de formulation considérant la définition quantitative de ces substances auxiliaires pour élaborer une forme de présentation donnée, obligent les acteurs du Développement à considerer une approche couplée Produit/Procédé. Dans cet esprit du Génie des produis formulés, l'objectif essentiel de cette étude, est, à partir d'un composant actif modèle, reconnu pour sa faible capacité à se solubiliser dans l'eau (l'ibuprofène) de développer des microparticules formulées permettant d'améliorer sa vitesse de dissolution en faisant appel à un procédé robuste, prenant en compte la protection de l'environnement, respectant les bonnes pratiques de fabrication et par ailleurs, économiquement applicable. Ainsi, une étude de mélanges physiques, puis celle du broyage, de l'évaporation de solvant et enfin de l'atomisation de suspensions actives en phase liquide majoritairement aqueuse a été menée. Des travaux réalisés, il ressort que l'amélioration de la vitesse de dissolution de l'ibuprofène dépend de la nature des adjuvantes de formulation et des méthodes de préparation utilisées. Dans les conditions expérimentales testées, nous avons pu démontrer tout l'intérêt de la valorisation du procédé d'atomisation, pour fournir des microparticules de morphologie et de granulométrie maîtrisées et présentant par ailleurs une aptitude à la dissolution in vitro qualifiée de rapide, comparativement à la matière actif originelle. Les performances de l'atomisation et la qualité des atomisats développées sont cependant très variables et dépendent : du type de surfactant et d'agent de séchage, mais également des paramètres propres au procédé (température notamment). Parmi les agents de séchage sélectionnées, nous avons pu dégager l'intérêt de l'utilisation de l'Aerosil 200® et tout particulièrement sa fonctionnalité à fournir des rendements de production satisfaisants. Pour ce qui est de l'utilisation de surfactants, les matières grasses gras (Tween 80®) se sont révélées peu efficaces comparativement aux surfactants solides de type lauryl sulfate de sodium et cétrimide. Pour ce qui est de la partie propre au procédé, il a été mis en évidence un intérêt à retenir et valorises le procédé d'atomisation pour ce type de production, intérêt que nous avons démontré, par une étude chimiométrique en plans d'expériences et une approche de transposition d'échelle sur un équipement pilote.MONTPELLIER-BU Pharmacie (341722105) / SudocSudocFranceF
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.
