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
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

Étude de la transmission d'Echinococcus multilocularis dans une grande agglomération : influence du comportement alimentaire et de l'utilisation de l'espace par le renard roux (Vulpes vulpes) sur la contamination de l'environnement.
No full textAlveolar Echinococcosis is a lethal zoonosis transmitted to humans by the ingestion of eggs of the tænia Echinococcus multilocularis. The cycle of the parasite needs a carnivore as definitive host (mainly the red fox) and the common and water voles (Microtus arvalis and Arvicola terrestris) as intermediate hosts. Since 20 years, the more and more common observations of urban foxes gave rise to many questions about the possible increased risk of transmission to man due to the proximity of foxes. Recent studies showed the presence of E. multilocularis in urban foxes with variable prevalence. However, the conditions of the development of this parasite in the urbanized area are few documented. Work presented here proposes to improve comprehension of the cycle of E. multilocularis in such urbanized area. A monitoring of the red fox infection by collection of road kills or trapped animals highlighted a "rural to urban" decreasing gradient of infection. Along this gradient, different habitats were regularly sampled; this study showed the importance for the red fox of the availability of Microtus sp. in waste land landscape. The study of the adaptation of its diet by red fox to the variations of rodents densities showed that the Microtus sp. was highly consumed even when it was poorly represented in the field whereas in peri-urban area, A. terrestris,is consumed according to its availability. Taking in account the availability of rodents on the scale of the city, it was shown that the consumption of intermediate hosts is more important in rural area than in urban area and that the rural diet exhibits a predominance of Microtus sp. versus A. terrestris whereas these differences are lacking in urban area. The distribution of faeces of the red fox appeared correlated with the densities of Microtus sp and A. terrestris, underlining the possibilities of closing the parasitic cycle whatever the urbanization level. Lastly, the study of foxes movements using GPS collars has allowed to observe various types of behaviours which could induce a modulation in the space dynamics of the urban transmission of the parasite based on the stability of the local red fox populations.L'Echinococcose Alveolaire est une zoonose mortelle transmise a l'Homme par l'ingestion des oeufs du tænia Echinococcus multilocularis. Le cycle du parasite fait intervenir un carnivore comme hote definitif (principalement le renard roux) et des campagnols prairiaux (Microtus arvalis et Arvicola terrestris) comme hotes intermediaires. Depuis une vingtaine d'annees, les observations de plus en plus frequentes de renards urbains ont suscite de nombreuses questions sur l'augmentation du risque de contamination humaine a cause de cette proximite des renards. Des etudes recentes ont montre la presence d'E. multilocularis chez le renard urbain avec des prevalences tres variables. Cependant, les conditions du developpement de ce parasite dans les milieux urbanises sont peu documentees. Les travaux presentes proposent d'ameliorer la comprehension du cycle d'E. multilocularis dans de tels milieux. Un suivi de l'infection vulpine par collecte de cadavres a mis en evidence un gradient d'infection decroissant du milieu rural au milieu urbain. Le long de ce gradient, differents milieux ont ete regulierement echantillonnes et ont montre l'importance pour le renard roux de la disponibilite en Microtus sp. dans les milieux friches. L'etude de la reponse alimentaire du renard roux aux variations de densites de rongeurs a montre que Microtus sp. etait fortement consomme meme lorsqu'il etait faiblement present sur le terrain alors que A. terrestris, en milieu peri-urbain, est consomme selon sa disponibilite. L'etude de la disponibilite en rongeurs a l'echelle de la ville montre que la consommation en hotes intermediaires est plus importante en milieu rural qu'en milieu urbain et que le regime alimentaire rural se caracterise par une predominance de Microtus sp. par rapport a A. terrestris alors que ces differences sont pas presentes en milieu urbain. La repartition des feces de renard roux est correlee aux densites de Microtus sp et d'A. terrestris, soulignant les possibilites d'existence du cycle parasitaire quel que soit le niveau d'urbanisation. Enfin, l'etude de trajectoires de renards par utilisation de colliers GPS a permis d'observer differents types de comportements individuels qui pourraient entrainer une modulation de la dynamique spatiale de la transmission urbaine du parasite basee sur la stabilite des populations vulpines
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.
