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
Diversity and evolution of the Ostreid Herpesvirus type 1
No full textL’utilisation des nouvelles générations de séquençage (NGS) pour étudier et surveiller les agents pathogènes chez les mollusques bivalves est cruciale pour anticiper la détection de nouveaux agents pathogènes ou l’émergence de nouveaux génotypes. Améliorer nos connaissances et nos techniques de caractérisation génomique permet de mieux appréhender le cycle de vie de ces agents pathogènes, leurs interactions avec les hôtes et de caractériser leur capacité d’adaptation et d’évolution. L’Ostreid Herpevirus 1 (OsHV-1), responsable chaque année de fortes mortalités chez les larves et les juvéniles d’huîtres creuses Magallana gigas. Ce virus a également été détecté chez d’autres espèces de bivalves associés à des mortalités. L’étude du génome d’OsHV-1 est rendue complexe par i) l’impossibilité de le cultiver in vitro car aucune lignée cellulaire pour le propager n’est disponible ii) la présence de grandes régions répétées inversées. En 2019, seuls six génomes du virus OsHV-1 étaient disponibles dans les bases de données publiques, limitant ainsi considérablement notre compréhension de sa diversité spatio-temporelle et parmi différentes espèces hôtes. Dans ce contexte, mes travaux de thèse ont été consacrés à l'acquisition et à l'assemblage de plus de 400 génomes du virus OsHV-1, grâce au développement d'un pipeline bioinformatique spécifiquement conçu pour son analyse génomique. L'analyse de ces génomes a permis de comprendre la structuration spatio-temporelle des populations du virus OsHV-1, notamment en lien avec les mouvements d'huîtres entre différentes zones ostréicoles en France. En complément, les résultats obtenus ont permis de caractériser l’isolement génétique des génotypes viraux de l’huître creuse M. gigas vis-à-vis de ceux retrouvés chez l’huître plate Ostrea edulis et d’inférer des fréquences de transmissions du virus inter-espèces quasi-nulles. Enfin, dans une approche d’évolution expérimentale, l’impact du fond génétique de l’hôte sur la diversité virale a été étudié, révélant l’influence conjointe de la dérive génétique et de la sélection essentiels dans l'évolution du virus OsHV-1. L'ensemble de ces travaux a contribué de manière significative à l'acquisition d’un grand nombre de données génomiques, favorisant ainsi une compréhension plus approfondie de la diversité, de l'évolution et de l'adaptation du virus à son hôte.Using next generation sequencing technologies (NGS) to study and monitor pathogens in bivalve mollusks is crucial for anticipating the detection of new pathogens or the emergence of new genotypes. Improving our knowledge and genomic characterization techniques allows for a better understanding of the life cycle of these pathogens, their interactions with hosts, and characterizing their capacity for adaptation and evolution. The Ostreid Herpesvirus 1 (OsHV-1) is responsible for significant mortalities in Pacific oyster (Magallana gigas) larvae and juveniles every year. This virus has been detected in other bivalve species associated with mortalities. Studying the OsHV-1 genome is challenging due to i) the inability to cultivate it in vitro because no cell line is available for propagation, and ii) the presence of large inverted repeat regions. In 2019, only six OsHV-1 virus genomes were available in public databases, significantly limiting our understanding of its spatiotemporal diversity across different host species. In this context, my doctoral research was dedicated to acquiring and assembling over 400 genomes of OsHV-1 virus, thanks to the development of a bioinformatics pipeline specifically designed for its genomic analysis. The analysis of these genomes helped elucidate the spatiotemporal structuring of OsHV-1 virus populations, particularly in relation to oyster movements between different oyster farming areas in France. Furthermore, the results obtained characterized the genetic isolation of viral genotypes in Pacific oysters M. gigas compared to those found in flat oysters Ostrea edulis and inferred nearly negligible inter-species virus transmission frequencies. Finally, in an experimental evolution approach, the impact of the host's genetic background on viral diversity was studied, revealing the joint influence of genetic drift and essential selection in the evolution of OsHV-1 virus. This work has significantly contributed to the acquisition of a substantial amount of genomic data, thereby promoting a deeper understanding of the diversity, evolution, and adaptation of the virus to its host
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.
