Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe 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
Get PDF“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
Get PDFWe 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
Get PDFWe 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
Influenza vaccine during pregnancy determinants
No full textContexte : Bien que la vaccination des femmes enceintes contre la grippe soit recommandée en France, la couverture vaccinale antigrippale reste très faible.Objectif : Identifier les déterminants du recours à la vaccination antigrippale et ceux d’une bonne connaissance concernant la grippe et la vaccination antigrippale chez les femmes enceintes ; chez les professionnels de santé : identifier les connaissances, les pratiques et les freins à la vaccination antigrippale.Matériel et Méthodes : Deux études prospectives observationnelles ont été réalisées durant la saison grippale 2014/2015. La première a été effectuée par auto-questionnaires auprès de toutes les femmes venant d’accoucher dans notre maternité universitaire ; la seconde a été menée à l’aide d’auto-questionnaires adressés à tous les professionnels de santé de notre réseau de périnatalité.Résultats : Parmi les 2045 femmes incluses dans notre étude (87%), 35% ont déclaré avoir été vaccinées contre la grippe pendant leur grossesse. Les déterminants du recours à la vaccination étaient : une vaccination antérieure contre la grippe, la nulliparité, un antécédent d’accouchement prématuré <34 SA, la perception que la fréquence des complications du vaccin est très faible chez le bébé, une bonne connaissance concernant la grippe et la vaccination antigrippale, une recommandation vaccinale par un professionnel de santé, avoir reçu le formulaire de remboursement et avoir été informée par au moins un professionnel de santé. Les déterminants d’une bonne connaissance étaient : un âge supérieur à 24 ans, un haut niveau d’éducation, un antécédent de vaccination contre la grippe, la nulliparité et une recommandation vaccinale par un professionnel de santé. Les 144 professionnels ayant répondu à notre questionnaire (41%) avaient des bonnes connaissances. Les principaux freins qu’ils rencontraient étaient le refus des patientes (54%), un manque de connaissance de leur part (32%) et un manque de temps (21%).Conclusion : La couverture vaccinale des femmes enceintes semble liée à plusieurs facteurs. Notre travail invite à mener des actions à destination des femmes enceintes, mais surtout des professionnels de santé qui les prennent en charge. Il s’agira d’améliorer leurs connaissances concernant la gravité de la maladie, l’efficacité du vaccin pour la mère et pour le bébé, ainsi que sa prise en charge totale par l’Assurance Maladie.Background: Although vaccination of pregnant women against influenza is recommended, the vaccination rate remains low. We have conducted a study to identify determinants of influenza vaccination uptake in pregnancy, determinant of a good knowledge and knowledge, practices and barriers reported by healthcare professionals with regard to influenza vaccination during pregnancy.Methods: We have conducted 2 studies. The first one was a prospective observational hospital-based study in the French hospital, performing the highest number of deliveries among all women who had given birth during the 2014–2015 influenza season. Data were collected through a self-completed survey and from medical files. Determinants of vaccination uptake and of a good knowledge were identified using logistic regression analysis. The second study was a prospective, observational, self-questionnaire-based study of healthcare professionals in a mother & child health network during the same period.Results: Among the 2045 women concerned by the study, 35.5% reported that they had been vaccinated against influenza during their pregnancy. The principal factors significantly associated with greater vaccination uptake were previous influenza vaccination, nulliparity, history of preterm delivery <34 weeks, the mother’s perception that the frequency of vaccine complications for babies is very low, the mother’s good knowledge of influenza and its vaccine, vaccination recommendations during pregnancy by a healthcare worker, receipt of a vaccine reimbursement form, and information from at least one healthcare worker about the vaccine. Determinants of the highest level of knowledge were age over 24, a high educational level, previous influenza vaccination, nulliparity, and the recommendation of vaccination by a healthcare professional. According to the 144 respondents, the main reported barriers to vaccination were refusal by the patient (54%), the healthcare professional’s admitted lack of knowledge about influenza and the influenza vaccine (32%), and a lack of time (20%).Conclusions: Our findings suggest that, in order to increase flu vaccination compliance among pregnant women, future public health programs must ensure cost-free access to vaccination, and incorporate education about the risks of influenza and the efficacy/safety of vaccination and clear recommendations from healthcare professionals into routine antenatal care
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.
