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
Evolution and synthesis of knowledge on an enigmatic neurological pathology : Nodding Syndrome
No full textLe Nodding Syndrome (NS) est une forme d’épilepsie atypique de l’enfant sévissant depuis de nombreuses années en Afrique de l’Est. L’objectif de cette thèse était de faire un état des lieux le plus exhaustif possible de cette pathologie. Pour atteindre cet objectif, nous avons d’abord confirmé, par une enquête de terrain, l’existence de cas de NS en République Centrafricaine, confirmant ainsi une extension vers l’Afrique Centrale. Ensuite, nous avons réalisé une revue systématique de la littérature qui nous a permis : 1) d’étudier la distribution géographique contemporaine des cas de NS (qui reste limité à l’Est et au Centre de l’Afrique) ; 2) d’identifier les limites et les défis liés à une définition inopérante de cette pathologie et ainsi d’en proposer une qui soit adaptée aux enquêtes épidémiologiques ; 3) de décrire les présentations cliniques particulières du NS ; 4) d’identifier les traitements utilisés et leurs alternatives et 5) de réaliser une synthèse détaillée des recherches à visée étiologique, puisque sa cause demeure toujours inconnue. Enfin, nous avons proposé un schéma d’étude multicentrique dont l’objectif principal porte sur les étiologies possibles/ probables du NS. Cette thèse a ainsi permis de mesurer ce fardeau de santé publique qui reste limité (pour l’instant) à l’Afrique sub-saharienne, et de souligner les nombreux défis auxquels la communauté scientifique doit faire face dans la lutte contre cette pathologie (aux rebondissements épidémiologiques imprévisibles). En regroupant et étudiant la quasi-totalité des publications afférant au NS jusqu’à la fin de l’année 2021, ce travail s'est voulu un apport indispensable pour une vision exhaustive de ce que l’on sait aujourd’hui sur le NS, et des questions qui restent en suspens. Les contributions sur les plans épidémiologique et clinique donneront peut-être de nouvelles orientations sur le sujet notamment une aide à la conception de stratégies de santé publique adaptées à chaque zone pour une meilleure prise en charge des enfants touchés par cette pathologie redoutable.The Nodding Syndrome (NS) is an atypical form of childhood epilepsy that has been prevalent in East Africa for many years. The aim of this thesis was to provide as comprehensive an overview as possible of this condition. To achieve this objective, we first confirmed, through a field survey, the existence of NS cases in the Central African Republic, thus confirming an extension to Central Africa. Next, we conducted a systematic review of the literature which allowed us to: 1) study the contemporary geographical distribution of NS cases (which remains limited to Eastern and Central Africa); 2) identify the limitations and challenges of an inoperative definition of the condition and thus propose one that is suitable for epidemiological investigations; 3) describe the particular clinical presentations of NS; 4) identify the treatments used and their alternatives; and 5) carry out a detailed synthesis of etiological research, since its cause remains unknown. Finally, we have proposed a multicentric survey with the main objective of investigating the possible/probable etiologies of NS. This thesis has thus made it possible to measure this public health burden, which remains limited (for the time being) to sub-Saharan Africa, and to highlight the many challenges facing the scientific community in the fight against this pathology (with its unpredictable epidemiological twists and turns). By gathering and studying almost all the publications on NS up to the end of the year 2021, this work aims at providing a comprehensive view of what is known about NS today, and of the questions that remain unanswered. The epidemiological and clinical contributions may provide new directions on the subject, including helping to design area-specific public health strategies for better management of children affected by this dreadful disease
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
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.
