    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

    “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

    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

    Improving the Management of Older Patients with Cancer : Identification Elements of Frailty

    No full text
    INTRODUCTION : La majorité des cancers survient chez la personne âgée. Cette population est hétérogène du fait de la prévalence de comorbidités, d’incapacités et de syndromes gériatriques contribuant à la fragilité. Ces éléments rendent complexe le choix de la stratégie thérapeutique à adopter. L’évaluation gériatrique approfondie (EGA) est recommandée pour évaluer la fragilité de ces patients. L’objectif général était d’identifier parmi les patients âgés de 70 ans et plus atteints de cancer, ceux qui présentaient un haut risque de morbi-mortalité afin de limiter les thérapeutiques agressives et proposer une prise en charge adaptée. Les objectifs spécifiques étaient : 1/d’identifier les facteurs oncologiques et paramètres de l’EGA conjointement associés au décès à 1 an, 2/d’identifier des profils de santé et de les valider sur la morbi-mortalité, 3/ d’évaluer la concordance entre 4 classifications de fragilité et de comparer leurs performances pronostiques. METHODES : ces travaux ont été réalisés à partir de la cohorte dynamique prospective ELCAPA (Elderly CAncer PAtient) qui inclut consécutivement tous les patients âgés de 70 ans et plus, avec un diagnostic de cancer solide ou hématologique et adressés en consultation d’oncogériatrie, dans 2 centres hospitalo-universitaires parisiens. Entre 2007 et 2012, 1 021 patients ont été inclus. Les critères de jugements étaient la mortalité globale à 1 an, les hospitalisations non programmées à 6 mois et la décision finale de traitement (curative, palliative). Nous avons analysé les facteurs associés au décès à 1 an de 993 patients à l’aide de modèles de Cox. Nous avons ensuite réalisé une analyse en classes latentes (ACL) sur cas-complets (n=821), avec analyses de sensibilité incluant les données manquantes (n= 1 021), puis selon le statut métastatique et validé cette typologie sur 375 nouveaux patients inclus dans la cohorte. La dernière étude a été réalisée sur 763 patients avec données complètes pour 4 classifications étudiées à l’aide de modèles de Cox (décès) et régression logistique (hospitalisations).RESULTATS: L’âge moyen était de 80,2 ans, 51,2% étaient des hommes, 21,4% avaient un cancer colorectal et 45% des métastases. Le nombre de comorbidités sévères (P≤0,05), la dénutrition (P80 ans (P≤0,05), le site tumoral et statut métastatique (P80 years (P<0.05), tumor site and metastatic status (P<0.001) were associated with death independently from impaired ECOG-PS (P<0.001), ADL (P<0.001), and GUG (P<0.001). LCA displayed 4 health profiles: those relatively healthy [LC1, 28.3%], malnourished [LC2, 35.8%], with cognitive and/or mood impairments [LC3, 15.1%], and gloablly impaired [LC4, 20 8%]. In adjusted pairwise comparisons, compared to LC1, the three other LCs were associated with higher risks of palliative treatment, death, and unplanned admission. LC4 was associated with 1-year mortality and palliative treatment compared to LC2 and LC3. For unplanned admissions, no differences were demonstrated across these three LCs. Patient distribution differed significantly across the four classifications, i.e., Latent class Typology, Balducci, SIOG1 and SIOG2 (P<0.001). Agreement between these four classifications was globally poor to moderate. For mortality, discrimination was good for the 4 models (C-index ≥0.70) with slightly better performance for SIOG 1-model. For hospitalizations, performance was good and close between the four models (C-index ≥0.70). None of the four classifications performed best for all the three tumor sites.CONCLUSIONS: We showed the usefulness of GA and especially some GA-parameters to identify among older patients, those who are frail. Intervention studies are needed to assess the impact of GA on morbi-mortality and quality of life of those patients

    koamabayili/VECTRON-author-checklist: VECTRON author checklist

    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.
