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
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

Understanding the determinants of HPV vaccine hesitancy in France
No full textCette thèse consiste en trois articles scientifiques s’intéressant aux facteurs influençant la couverture vaccinale par le vaccin anti-HPV. Plus spécifiquement, elle analyse les facteurs liés à cette vaccination chez les mères de filles âgées de 11 à 14 ans en France métropolitaine, sous l’angle de l’hésitation vaccinale. Le premier article restitue l’élaboration d’un instrument visant à interroger les facteurs influençant la couverture vaccinale par le vaccin anti-HPV, selon le modèle conceptuel des déterminants de l’hésitation vaccinale de l’OMS. Nous nous sommes appuyés sur une revue de la littérature scientifique de questionnaires validés, et sur un panel multidisciplinaire d’une quinzaine d’experts sollicités selon la méthodologie de Delphi. Cette consultation réalisée sur Internet en deux tours a permis d’identifier 57 questions. Le deuxième article présente les résultats d’une enquête téléphonique menée sur un échantillon représentatif de 1102 mères de filles âgées de 11 à 14 ans sélectionné par la méthode des quotas, faisant suite à une phase pilote testant l’instrument du premier article sur un échantillon représentatif d’une trentaine de mères. Les entretiens comprenaient des questions additionnelles, et avaient été conduits selon la méthode d’entretien téléphonique assisté par ordinateur. Le facteur le plus fortement négativement associé à la vaccination anti-HPV était l'âge de l'adolescente : la croyance de la mère selon laquelle sa fille était trop jeune pour être vaccinée (OR=0,16 ; IC95% 0,09-0,29), et l'âge plus jeune de l'adolescente (OR=0,17 ; IC95%, 0,10-0,28 pour les filles âgées de 11 ans par rapport à celles âgées de 14 ans). Deux facteurs étaient positivement associés à la couverture vaccinale : être en accord avec l'affirmation selon laquelle les médecins croient que vacciner les filles contre les HPV est une bonne idée, et avoir posé des questions au médecin traitant sur les vaccins HPV (OR=4,99 ; IC95%, 2,09-11,89 ; et OR=3,44 ; IC95 %, 2,40-4,92, respectivement). Le troisième article présente une analyse secondaire des données de l’enquête Vaccinoscopie® visant à évaluer le rôle du recours à Internet comme source d’information sur la vaccination chez les mères hésitantes vis-à-vis de cette vaccination, sur la vaccination anti-HPV de leurs filles. Nous avons réalisé une analyse poolée des données de 2015 à 2018 portant sur les mères de filles âgées de 14 et 15 ans, d’abord à travers un modèle de régression logistique multivarié, puis par des modèles d’équations structurelles. La régression logistique ajustée sur la recommandation de la vaccination anti-HPV par le médecin, les attitudes à l'égard des vaccins en général, la perception de l'utilité du vaccin anti-HPV, le niveau d'éducation de la mère, la région de résidence et l'année de l'enquête montrait que l’utilisation d'Internet par les mères était significativement associée à une moindre vaccination anti-HPV chez leurs filles (OR=0,66 ; IC95%, 0,47-0,91). Les modèles d’équations structurelles ont confirmé l'effet négatif de l'utilisation d'Internet, en révélant les liens mécanistiques sous-jacents à la moindre couverture vaccinale du vaccin anti-HPV. Les résultats de cette thèse ont des implications en matière de politiques publiques de vaccination anti-HPV. Ils interrogent notamment sur l’opportunité d’abaisser le seuil d’éligibilité de la vaccination anti-HPV en population générale de 11 à 9 ans et soulignent, entre autres, la nécessité de renforcer la formation et l’implication des médecins généralistes quant à la recommandation de vacciner contre les HPV.This thesis consists of three scientific articles related to the factors influencing HPV vaccine coverage. More specifically, it analyses the factors linked to this vaccination among mothers of girls aged 11 to 14 years in metropolitan France, from the perspective of vaccine hesitancy. The first article reports on the development of an instrument that questions the factors involved in HPV vaccination uptake using the World Health Organization conceptual model of determinants of vaccine hesitancy. We relied on a review of the scientific literature of validated questionnaires, and on a multidisciplinary panel of fifteen experts solicited using the Delphi methodology. This two-round web-based consultation led to the inclusion of 57 questions in the instrument. The second article presents the results of a telephone survey among a representative sample of 1102 mothers of girls aged 11 to 14 years in metropolitan France, selected by the quota method, following the pilot testing of the instrument of the first article among a representative sample of thirty mothers. The interviews included additional questions and were conducted using the computer-assisted telephone interviewing method. The strongest factor negatively associated with HPV vaccination uptake was the age of the adolescent girl: mother's belief that her daughter was too young to be vaccinated (OR=0.16; CI95% 0.09-0.29), and the younger age of the adolescent girl (OR=0.17; CI95%, 0.10-0.28 for girls aged 11 years compared to those aged 14 years). Two factors were positively associated with HPV vaccination uptake: agreeing with the statement that doctors believe that vaccinating girls against HPV is a good idea, and having asked questions to the attending doctor about HPV vaccines (OR=4.99; CI95%, 2.09-11.89, and OR=3.44; CI95%, 2.40-4.92, respectively). The third paper presents a secondary analysis of the Vaccinoscopie® survey data assessing the role of Internet use as a source of information on vaccination among vaccine-hesitant mothers on their daughters' HPV vaccination uptake. We performed a pooled analysis of data from 2015 to 2018 in mothers of 14- and 15-year-old girls, first through a multivariate logistic regression model, then through structural equation modeling. Logistic regression adjusted for physician recommendation of HPV vaccination, attitudes towards vaccines in general, perceived usefulness of the HPV vaccine, mother's education level, region of residence, and survey year, showed that mothers' use of the internet was significantly associated with a lower HPV vaccination uptake in their daughters (OR= 0.66; CI95%, 0.47-0.91). The structural equation modeling confirmed the negative effect of Internet use, revealing the underlying mechanistic links leading to lower HPV vaccine uptake. The results of this thesis have implications for public policy on HPV vaccination. They raise questions, in particular, about the opportunity of lowering the eligibility threshold for HPV vaccination in the general population from 11 to 9 years. Furthermore, they emphasize the need to strengthen the training and involvement of general practitioners in recommending HPV vaccination
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.
