    The 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

    “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 text
    We 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

    We 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 text
    We 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

    Microparticles analysis in systemic lupus erythematosus

    Introduction : le lupus érythémateux systémique est une maladie auto-immune dont l’évolution est marquée par l’alternance de phases de rémission et de poussées difficilement prévisibles. De ce fait, le développement de nouveaux biomarqueurs permettant d’ajuster les traitements immunosuppresseur avant les poussées est attendu. De précédentes études suggèrent que les patients atteints de lupus présentent une augmentation importante du taux de microparticules (MPs). Le nombre de MPs pourrait corréler à l’activité de la maladie et être à ce titre utiliser comme biomarqueur d’activité. Objectif : étudier les microparticules plaquettaire, endothéliales et granulocytaires circulantes dans une cohorte de patients atteints de lupus et d’établir les microparticules plaquettaires P-sélectine positive (PMPs Psel+) comme biomarqueur d’activité. Méthodes : nous avons inclus de façon prospective 67 patients suivis au CHU de Bordeaux. Les échantillons sanguins des patients et des sujets contrôles étaient prélevés par ponction veineuse et traitées de façon à obtenir du plasma dépourvu de plaquette qui était stocké à -80° jusqu’à l’analyse. Le nombre de MPs de chaque sous type était déterminé par cytométrie de flux. Résultats : au total, le nombre global de MPs/μL était de 6579 (IQR: 4175-19887) chez les patients et 3055 (IQR: 2710-3965) chez les sujets contrôles (p <0,0001). Les patients actifs avaient plus de PMPs Psel+ que les contrôles (677 vs 82, p <0.0001) et les sujets non-actifs (677 vs 199, p=0.03). De plus, le nombre de PMPs Psel+ corrélait positivement avec l’activité de la maladie évalué par le SLE disease activity index (SLEDAI). Les PMPs Psel+ avaient une meilleure valeur discriminative que les MPs et les anticorps anti-dsDNA pour distinguer les patients non-actifs des patients en poussée. L’analyse longitudinal au cours du temps a révélé que le nombre de PMPs Psel+ évoluaient de façon très proche des modifications du SLEDAI suggérant qu’elles pourraient être un bon biomarqueur d’activité. L’analyse des MPs granulocytaire (GMPs) souligne qu’un tiers des patients présentaient un profile High-GMPs dans le sang, celui-ci était associé à une plus forte activité de la maladie et une fréquence plus élevé d’anticorps anti-phospholipides. Conclusion : nous démontrons que les patients lupiques ont non seulement un nombre plus élevé de MPs mais surtout un plus grand nombre de MPs sélectine positives. Nous montrons également que les PMPs Psel+ peuvent être un biomarqueur d’activité de la maladie.Introduction: systemic lupus erythematosus (SLE) is an autoimmune disease that alternates between remission phase and hardly predictable flare-up. Therefore, the development of new disease activity biomarkers which could help to adjust immunosuppressive treatments before flare-up is urgently needed. Previous studies suggested that SLE patients have a higher number of microparticles (MPs) than healthy controls. MPs absolute count may correlate to disease activity and be used as a biomarker of disease activity in SLE patients. Objective: we aimed to investigate circulating platelet-, endothelial- and granulocyte-derived MPs in a cohort of SLE patients and to assess P-selectin positive MPs (PMPs Psel+) as a potential disease activity biomarker. Methods: we prospectively included 67 consecutive SLE patients followed in Bordeaux University Hospital. Blood samples from patients and controls were collected by venipuncture and processed to obtain platelet-free plasma which was stored at −80 °C until MPs analysis. Absolute counts of subset-specific circulating isolated MPs were characterized by flow cytometry. Results: overall, the median numbers of MPs/μL measured in the blood were 6579 (IQR: 4175-19887) in SLE patients and 3055 (IQR: 2710-3965) in controls (p <0,0001). Active SLE patients had more PMPs Psel+ compared to controls (677 vs 82, p <0.0001) and non-active patients (677 vs 199, p=0.03). Moreover, there was a positive correlation between PMPs Psel+ absolute count and disease activity assessed by the SLE disease activity index (SLEDAI). PMPs Psel+ yielded a higher discriminative value than MPs and anti-double stranded DNA (anti-dsDNA) to distinguish quiescent patients from those with flare-up. The longitudinal characterization of MPs over time revealed that PMPs Psel+ followed the changes of SLEDAI score in a really accurate way suggesting that it could be a good biomarker of disease activity. The assessment of granulocyte-MPs (GMPs) highlighted that one third of patients displayed a high-GMPs profile in their blood which was associated with a higher active disease and a higher proportion of antiphospholipid antibodies. Conclusion: we demonstrated that SLE patients not only have a higher number of circulating MPs in the blood but especially more selectins-positive MPs. In addition, we showed that PMPs Psel+ is a potential biomarker of disease activity since the number of PMPs Psel+ is correlated and evolve in the same way than SLEDAI score in a longitudinal analysis

    Author Under Sail The Imagination of Jack London, 1893-1902

    No full text
    In 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.
