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

Child physical abuse : clinical and population-based epidemiology
No full textLa maltraitance physique infantile (MPI) est une situation pathologique qui a des spécificités qui rendent sa prévention, son repérage, son diagnostic, sa prise en charge et son étude scientifique complexes. Les objectifs de ce travail doctoral étaient d'utiliser des approches d'épidémiologie clinique et populationnelle pour améliorer les connaissances sur l'épidémiologie, le repérage et le diagnostic de la MPI. Pour répondre à ces objectifs, nous avons utilisé successivement (i) la base de données hospitalières de l'hôpital Necker-Enfants malades pour évaluer, par des analyses de séries temporelles, l'impact de la pandémie COVID-19 sur l'incidence et la gravité des traumatismes crâniens non accidentels (TCNA) chez des nourrissons de moins de 2 ans en Ile-de-France ; (ii) la base de données hospitalières du centre hospitalier universitaire de Nantes pour étudier, selon la méthode des enquêtes confidentielles avec comité d'experts, l'optimalité du parcours de soin des enfants de moins de 6 ans hospitalisés pour MPI sévère ; (iii) la base de données MEDLINE (via PubMed) et les sites internet des agences sanitaires et des sociétés savantes des pays avec une économie avancée afin de comparer les recommandations cliniques nationales et internationales publiées depuis 2010 pour le repérage et le diagnostic de la MPI. Nous avons montré que l'incidence mensuelle du TCNA était stable en 2020 (rapport des taux d'incidence ajustés -RTIa- : 1,02 [IC 95% 0,59-1,77]) puis avait doublé en 2021 (RTIa : 1,92 [1,23-2,99]) par rapport à la période pré-pandémique, avec une mortalité multipliée par 9 (odds-ratio 9,39 [IC 95% 1,88-47,00]). Nous avons démontré qu'un tiers des enfants victimes de MPI avait un parcours de soin avant diagnostic jugé comme suboptimal par les experts. Nous avons identifié 2 catégories non exclusives de soins suboptimaux : le « retard diagnostique » et la « prévention secondaire inefficace ». Enfin, nous avons identifié une très grande hétérogénéité entre les recommandations cliniques pour le repérage et le diagnostic de la MPI produites dans différents pays que ce soit la définition des lésions sentinelles, les examens à réaliser pour le diagnostic positif de la MPI ou les diagnostics différentiels. L'ensemble de ces travaux a permis de mettre en évidence la nécessité (i) d'accompagner les mesures de confinement de programmes ambitieux de prévention et de repérage du TCNA, (ii) de mieux former le personnel de la petite enfance sur les signes et symptômes de la MPI pour en raccourcir les délais diagnostiques, et (iii) d'élaborer des recommandations internationales standardisées afin de contribuer à l'optimisation des pratiques cliniques dans le futur.Child physical abuse (CPA) is a pathological situation with specificities that make its prevention, detection, diagnosis, management and scientific study complex. The objectives of this doctoral work were to use clinical and population-based epidemiological approaches to improve knowledge on the epidemiology, detection and diagnosis of CPA. To reach these objectives, we successively used (i) the hospital database of the Necker Hospital for Sick Children to evaluate, using time series analyses, the impact of the COVID-19 pandemic on the incidence and severity of abusive head trauma (AHT) in infants under 2 years of age in the Paris metropolitan area; (ii) the hospital database of the University Hospital of Nantes to study, using the confidential survey method with expert committee, the optimality of the care pathway of children under 6 years of age hospitalized for severe CPA; (iii) the MEDLINE database (via PubMed) and the websites of health agencies and academic societies in high income countries to compare the national and international clinical guidelines published since 2010 for the detection and diagnosis of CPA. We showed that the monthly incidence of AHT was stable in 2020 (adjusted incidence rate ratio -aIRR-: 1.02 [95% CI 0.59-1.77]) and then doubled in 2021 (aIRR: 1.92 [1.23-2.99]) compared with the pre-pandemic period, with a 9-fold increase in mortality (odds ratio 9.39 [95% CI 1.88-47.00]). We demonstrated that one third of children with CPA had a care pathway before diagnosis that was judged suboptimal by experts. We identified 2 non-exclusive categories of suboptimal care: "diagnostic delay" and "ineffective secondary prevention". Finally, we identified a substantial heterogeneity between the clinical guidelines for the detection and diagnosis of CPA produced in different countries, regarding the definition of sentinel injuries, the tests to be performed for the positive diagnosis of CPA and the differential diagnoses. These findings have highlighted the need to (i) support containment measures with ambitious AHT prevention and detection programs; (ii) better train early childhood professionals on the signs and symptoms of CPA to reduce diagnostic delays and (iii) develop standardized guidelines to help optimize clinical practice in the future
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.
