Going Beyond Counting First Authors in Author Co-citation Analysis
No full textThe 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
No full text“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
No full textWe 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
No full textWe 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
Characterization of Calophyllum inophyllum L. resins : dereplicative approach for the search of antimicrobial compounds
No full textCalophyllum inophyllum L. est une plante tropicale très répandue, de la famille des Calophyllaceae. L’huile obtenue par pression à froid des fruits de l’arbre (‘’huile de Tamanu’’) est employée dans le monde, au-delà des usages traditionnels des îles du Pacifique, pour ses propriétés dermatologiques. L’huile est dotée d’une fraction résineuse, riche en métabolites secondaires de type coumarines et dérivés, et responsable des propriétés biologiques et notamment antimicrobiennes, de celle-ci. La résine, précipitée à l’éthanol à partir de l’huile alors utilisée dans les spas et instituts de massage, est verte et odorante, et se prête ainsi mal aux critères d’emploi dans l’industrie dermo-cosmétique. Cette dernière, bien que portant un intérêt biologique, constitue alors un sous-produit de l’industrie cosmétique, non valorisé aujourd’hui. La résine du tronc de cet arbre, bien qu’employée dès le XVIIIe siècle en France métropolitaine sous le nom de ‘’Gomme de Tacamaque’’ ou ‘’Baume Vert’’, pour soigner les articulations et troubles dentaires, est quant à elle très peu rapportée dans la littérature, et son utilisation est aujourd’hui tombée en désuétude. C’est dans ce contexte et avec l’émergence de nouveaux outils de déréplication que les relations contenu/activité antimicrobienne de ces résines ont été étudiées dans ces travaux. L’empreinte moléculaire par la méthode des réseaux moléculaires a été réalisée pour chacune des deux résines, à partir des analyses UHPLC-HRMS², et les réseaux moléculaires ont été annotés par un indice d’activité antimicrobienne : la concentration minimale inhibitrice (CMI), et par des marqueurs préalablement isolés, certains pour la première fois de la résine d’huile, et un composé nouveau à partir de la résine de tronc. L’empreinte moléculaire de la résine de tronc a également été comparée avec celle d’échantillons muséaux provenant du musée de drogues végétales François Tillequin (Paris Descartes), par les réseaux moléculaires afin de vérifier la traçabilité d’échantillons anciens. Une dégradation mimée de la résine de tronc fraîche a aussi été réalisée dans ce contexte et cette étude a été complétée par une approche déréplicative par RMN.Calophyllum inophyllum L. is a widespread tropical tree belongs to Calophyllaceae family. The oil obtained from its fruits ("Tamanu oil") is used all around the world to treat dermatological diseases beyond its traditional Polynesian uses. The oil contains a resinous fraction with a high content of secondary metabolites and specially coumarins. These molecules are responsible for the biological activities of the oil such as antimicrobial behaviour. The resinous fraction precipitated from the oil with ethanol, is green and odorous and not suitable for cosmetics uses. The oil without its resinous fraction is used for massages. Thus, the resin from the fruit oil is a by-product for cosmetic industry. Furthermore, bark resin (called ‘’Gomme Tacamaque’’ or ‘’Baume Vert”) was used in metropolitan France in the eighteenth century to treat the joints and dental disorders but is not well known in the literature and is not still used. In this context, and thanks to the emergence of new dereplicative tools, we studied the content/antimicrobial activity relationship of these resins. The molecular fingerprint of each resin was made by molecular networks from UHPLC-ESI-Q-TOF-HRMS² analysis. Molecular networks were annotated with the minimal inhibitory concentration (MIC) previously determined, and with isolated markers. One of these markers was isolated for the first time from the oil resin and isolated compound from the bark resin is a new molecule. Molecular fingerprint of the bark resin and from museum samples from the François Tillequin museum (Paris Descartes) were compared thanks to molecular networks to confirm the traceability of old samples. The fresh resin was also degraded to be compared to museum resins. This study was completed by NMR dereplication approach

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.
