    Going Beyond Counting First Authors in Author Co-citation Analysis

    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” 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 link
    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

    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.

    Médecine généraleContexte. Le nombre de patients nonagénaires ne cesse d'augmenter ces dernières années. L'allongement de l'espérance de vie s'accompagne d'une hausse de la prévalence des maladies cardiaques dégénératives, notamment de la sténose aortique. Le but de cette étude est de comparer les résultats des procédures d'implantation de valves aortiques percutanées (TAVI) chez les patients de plus de 90 ans par rapport au reste de la population. Les objectifs secondaires sont d'analyser les différentes complications cardio-vasculaires entre les deux groupes ainsi que la qualité de vie. Méthodes. Nous avons inclus l'ensemble des patients ayant bénéficié d'une procédure par TAVI au CHU de Strasbourg entre 2010 et 2019. Les données concernant les caractéristiques des patients, les détails de la procédure, les résultats et les complications ont été recueillis de manière prospective dans la base de données FRANCE-2 et FRANCE-TAVI. Nous avons réalisé une analyse de survie entre les deux groupes ainsi qu'une analyse comparative des principales complications. Dans un second temps, la qualité de vie des patients nonagénaires encore en vie a été évaluée à l'aide d'un questionnaire standardisé EQ 5D 5L évaluant 5 items : la mobilité, l'autonomie, les activités de la vie courante, la douleur ou inconfort, l'état d'anxiété ou de dépression. L'amélioration de la dyspnée, le vécu de l'opération et la cotation de santé entre 0 et 100 ont également été relevées. Résultats. Sur 1125 patients inclus, 151 (13 %) avaient plus de 90 ans. La survie à 30 jours était de 95 % pour les patients nonagénaires contre 95,3% pour les patients plus jeunes et la survie à 1 an était de 82,7 % pour les patients nonagénaires contre 85,5% pour les patients de moins de 90 ans. À un suivi de 5 ans, la survie actuarielle était plus faible chez les nonagénaires comparativement au reste de la population (23,7 vs. 32,8 (LogRank 0.003)). Nous avons relevé de façon significative davantage de bloc auriculo-ventriculaire per procédure, de complications vasculaires majeures, de complications hémorragiques immédiates avec nécessité de transfusion, ainsi que davantage d'évènements cardio-vasculaires majeurs dans le groupe des patients nonagénaires (p-0,05). Il n'y avait pas de différences significatives pour les autres paramètres étudiés. L'étude de la qualité de vie réalisée sur 49 patients montrait quant à elle une amélioration du stade de dyspnée d'un demi stade NYHA, un bon vécu de l'opération, un score de qualité de vie moyen de 55,4/100 et une amélioration subjective de l'autonomie. Le taux de satisfaction de l'intervention était de 87,8% et 85,7% des patients étaient prêts à refaire cette intervention si nécessaire. Conclusion. Les résultats du TAVI sur une population de patients nonagénaires selectionnée sont bons en dépit d'une mortalité plus élevée à moyen terme. Le bénéfice obtenu sur la qualité de vie donne satisfaction à une large majorité des patients.Context. The last years have seen a constant increase of nonagerian patients. The longer life expectancy comes with a higher prevalence of degenerative cardiac diseases, in particular that of the aortic stenosis. This study aims to compare the outcomes of transcatheter aortic valve implantations (TAVI) in over 90 years old patients as opposed to TAVI procedures in under 90 years old. Secondary objectives are the comparison of various cardiovascular complications in the two groups, as well as a quality of life study. Methods. Included in the study are all patients having undergone TAVI procedures at the Strasburg CHU between 2010 and 2019. Data relative to patient characteristics, details of the procedure, results, and complications were gathered through the FRANCE-2 et France-TAVI data banks. We performed a survival analysis for both groups as well as a comparative study of the major complications. Further, a quality of life assessment was conducted for those nonagerian patients alive in 2020 **(give a date here, a year)** using the standardised questionnaire EQ 5D 5L. The questionnaire targets the five dimensions of mobility, self-care, usual activities, pain and discomfort, and anxiety and depression. Also recorded were improvement of dyspnoea, the experience of the intervention, and self-assessment of health status on a scale of 0 to 100. Results. Out of the 1125 patients included, 151 (13 %) were over 90 years old. Survival rate at 30 days was 95 % for the latter patients and 95.3 % for the younger ones, and the rate at one year was 82.7 % against 85.5 %. At 5 years, acturial survival for the over 90 years old was 23.7 % against 32.8 % for the remainder of the patients (logrank 0.003). Also for the over 90 years old, we noted a significative increase of atrioventricular block per procedure, of major vascular complications, immediate bleeding complications requiring transfusions, as well as more major cardiovascular events (p - 0.05). There were no significant differences for the other factors studied. The quality of life study for the 49 patients concerned showed an improvement of the dyspnoea class by a half class NYHA, a good experience of the operation, an average quality of life score of 55.4/100, and a subjective improvement in self-care. The rate of satisfaction over the TAVI procedure was of 94 % among the patients, and 93 % of them were prepared to repeat it if necessary. Conclusion. Outcomes of TAVI procedures for the selected population of over 90 years old were good despite a higher mid-term mortality. Quality of life benefits have been experienced by a large majority of patients
