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
Résistance aux antimicrobiens d\u27Escherichia coli et de Klebsiella spp. isolés de volailles dans la commune de Mont-Ngafula à Kinshasa, République démocratique du Congo
No full textBackground: In poultry farming, the widespread use of antibiotics to prevent and treat infections and promote growth has led to the emergence of resistant bacteria. As a result, bacterial infections can spread in the environment, contaminating humans and other animals. Aim: To assess the sensitivity of enterobacteria to antibiotics on poultry farms in the peri-urban area of Kinshasa, by analyzing fecal samples collected from poultry, including laying hens, broilers and ducks in the commune of Mont-Ngafula. Methods: Antibiotic-resistant enterobacteria were identified with a classic gallery and sensitivity tests were conducted on the isolated strains using the disk diffusion method with Mueller Hinton agar. Results: Sample analyses identified 64 bacterial isolates, including 60 Escherichia coli isolates (94%) and 4 Klebsiella spp. isolates (6%). Antibiotic sensitivity tests revealed resistance to amoxicillin (83.3%), ampicillin (83.3%) and sulfadimidine (83.3%), while all isolates were sensitive to gentamicin and cefuroxime (100%). Conclusions: The high bacterial resistance to a wide range of antibiotics in poultry constitutes a serious risk, which must be addressed by the structures responsible for animal and public health. A more in-depth study would improve our understanding of the antimicrobial resistance observed in poultry in Kinshasa.Contexto: En avicultura, la utilización generalizada de antibióticos para prevenir y tratar las infecciones y favorecer el crecimiento ha hecho emerger bacterias resistentes que pueden propagarse en el medio ambiente y contaminar al hombre y a los demás animales. Objetivo: Para evaluar la sensibilidad de las enterobacterias a los antibióticos, nuestro estudio se interesa por la cría de aves de corral de la comuna de Mont-Ngafula, en la zona periurbana de Kinsasa. Métodos: Se aislaron enterobacterias resistentes a los antibióticos a partir de muestras fecales tomadas en aves de corral, especialmente gallinas ponedoras, pollos para carne y patos. Se identificaron con una galería clásica y se realizaron pruebas de sensibilidad con la ayuda del método de difusión por disco sobre gelosa de Mueller Hinton. Resultados: El análisis de las muestras permitió identificar 64 cepas bacterianas aisladas, entre las cuales había 60 cepas de Escherichia coli (94 %) y 4 cepas de Klebsiella spp. (6 %). Las pruebas de sensibilidad a los antibióticos revelaron una resistencia a la amoxicilina (83,3 %), a la ampicilina (83,3 %) y a la sulfadimidina (83,3 %), mientras que todas las cepas bacterianas aisladas eran sensibles a la gentamicina y a la cefuroxima (100 %). Conclusiones: Esta fuerte resistencia de las bacterias a una amplia gama de antibióticos en las aves de corral constituye un serio riesgo, que deben tener en cuenta las estructuras encargadas de la salud animal y de la salud pública. Un estudio más profundo permitiría mejorar nuestra comprensión de la resistencia observada en las aves de corral de Kinsasa.Contexte : En aviculture, l’utilisation généralisée d’antibiotiques pour prévenir et traiter les infections et favoriser la croissance a conduit à l’émergence de bactéries résistantes qui peuvent se propager dans l’environnement et contaminer l’homme et les autres animaux. Objectif : Afin d’évaluer la sensibilité des entérobactéries aux antibiotiques, notre étude s’est intéressée aux élevages de volailles dans la commune de Mont-Ngafula en zone périurbaine de Kinshasa. Méthodes : Des entérobactéries résistantes aux antibiotiques ont été isolées à partir d’échantillons fécaux prélevés sur des volailles, notamment des poules pondeuses, des poulets de chair et des canards. Elles ont été identifiées avec une galerie classique et des tests de sensibilité ont été réalisés à l’aide de la méthode de diffusion par disque sur gélose de Mueller Hinton. Résultats : L’analyse des échantillons a permis d’identifier 64 isolats bactériens, dont 60 isolats d’Escherichia coli (94%) et 4 isolats de Klebsiella spp. (6%). Les tests de sensibilité aux antibiotiques ont révélé une résistance à l’Amoxicilline (83,3%), à l’Ampicilline (83,3%) et à la Sulfadimidine (83,3%), tandis que tous les isolats étaient sensibles à la Gentamicine et à la Cefuroxime (100%). Conclusions : Cette forte résistance de bactéries à une large gamme d’antibiotiques chez les volailles constitue un sérieux risque, qui doit être pris en compte par les structures en charge de la santé animale et de la santé publique. Une étude plus approfondie permettrait d’améliorer notre compréhension de la résistance observée chez les volailles à Kinshasa
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

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.
