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
Comparative study of the multi-allergenic screening tests PHADIATOP and SX01 in the screening of respiratory, ENT and ophthalmic allergies
No full textIntroduction : les allergies causées par les pneumallergènes sont parmi les maladies chroniques les plus fréquentes au monde, elles pourraient toucher 50% de la population mondiale d’ici 2050. Ce sont également des maladies largement sous diagnostiquées. Le dosage PHADIATOP® (ThermoFischer) est un test de dépistage multi-allergénique (mélange d’allergènes extraits), considéré comme référence en Europe. Sa spécificité et sa sensibilité sont supérieures à 80-90%, ce qui en fait une bonne première approche diagnostique de l'allergie respiratoire pour le médecin sans compétence allergologique. Nous avons comparé les performances du PHADIATOP avec celles d’un autre test de dépistage multi-allergénique : le Sx01 (Hycor), nouveau sur le marché, composé d’allergènes moléculaires modulables par le biologiste. Matériel Et Méthodes : nous avons effectué une étude observationnelle rétrospective transversale : Dans un premier temps, les sérums de patients ayant effectué un test PHADIATOP® au CHU de Bordeaux durant la période d’inclusion ont été testés avec le test Sx01 pour comparer leur performances diagnostiques biologiques. Dans un deuxième temps, un recueil clinique a été effectué sur l’ensemble des sérums analysés pour comparer leurs performances diagnostiques cliniques. Résultats : nous avons retrouvé de très bonnes performances pour le test Sx01, qui est non inférieur au test PHADIATOP®, avec comparativement une sensibilité de 85,96%, une spécificité de 98,09%, une valeur prédictive positive de 94,23% et une valeur prédictive négative de 95,06% (p < 0,01). Les discordances portaient principalement sur la sensibilisation aux moisissures. Comparativement à la clinique, nous avons retrouvé respectivement pour PHADIATOP® et Sx01 une sensibilité de 88,46% et 97,87%, une spécificité de 94,96% et 95,14%, une valeur prédictive positive de 86,79% et 86,79% et une valeur prédictive négative de 95,65% et 99,28% (p < 0,01). Conclusion : cette étude de comparaison des performances diagnostiques biologiques et cliniques des tests PHADIATOP® et Sx01 montre des résultats très prometteurs pour le Sx01 en termes de performance diagnostique, ce qui en ferait un très bon test de dépistage. De plus, il présente des caractéristiques techniques rendant son utilisation particulièrement intéressante, notamment la possibilité de s’adapter aux allergènes selon leur répartition territoriale.Introduction: allergies caused by pneumallergens are among the most common chronic diseases in the world, they could affect 50% of the world population by 2050. They are also largely underdiagnosed diseases. The PHADIATOP® assay (ThermoFischer) is a multi-allergenic screening test (mixture of extract allergens), considered a reference in Europe. Its specificity and sensitivity are greater than 80-90%, which makes it a good first diagnostic approach to respiratory allergy for doctors without allergological expertise. We compared the performances of PHADIATOP with those of another multi-allergenic screening test: Sx01 (Hycor), new on the market, composed of molecular allergens that can be modulated by the biologist. Material and methods: we carried out a retrospective, cross-sectional observational study. Firstly, sera from patients who performed a PHADIATOP® test at Bordeaux University Hospital during the inclusion period were tested with the Sx01 test to compare their biological diagnostic performance. Secondly, a clinical collection was carried out on all the sera analyzed to compare their clinical diagnostic performances. Results: we found very good performance for the Sx01 test, which is non-inferior to the PHADIATOP® test, with comparatively a sensitivity of 85.96%, a specificity of 98.09%, a positive predictive value of 94.23% and a negative predictive value of 95.06% (p < 0.01). The discrepancies mainly concerned mold sensitization. In the complementary clinical study, we found respectively for PHADIATOP® and Sx01 a sensitivity of 88.46% and 97.87%, a specificity of 94.96% and 95.14%, a positive predictive value of 86.79% and 86.79% and a negative predictive value of 95.65% and 99.28% (p < 0.01). Conclusion: this comparison study of the biological and clinical diagnostic performances of the PHADIATOP® and Sx01 tests shows very promising results for Sx01 in terms of diagnostic performance, which would make it a very good screening test. In addition, it has technical characteristics making its use particularly interesting, in particular the possibility of adapting to allergens according to their territorial distribution
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.
