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
La Naissance de l'idée de photographie.
No full textLa naissance de l'idée de photographie, Paris, PUF, 2011.A milestone work that examines the democratic idea of photography and its expansion in common culture, particularly in the United States; generously illustrated.This influential text by French historian and theorist François Brunet considers the invention and history of photography as the birth of an idea, rather than a new type of image. This “idea photography” combines a logical theme—that of an art without artistry—and the democratic political promise of an art for all. Officially endorsed by the 1839 French law on the daguerreotype, this idea reverberated throughout the nineteenth century in Europe and America. Brunet shows how emerging image technologies and practices in France and Britain were linked to this logical/political construction of photography, from the earliest researches of Nicéphore Niépce, Louis-Jacques-Mandé Daguerre, and Henry Fox Talbot up to the turn of the twentieth century. The parallel development of the Kodak camera and Alfred Stieglitz's “straight” vision in the United States then fulfilled, while also depreciating, the utopian promise of photography for all. This history reached a provisional climax with the reflections on images by Ralph Waldo Emerson, Hippolyte Adolphe Taine, Sigmund Freud, Henri-Louis Bergson, and Charles Sanders Peirce, reflections that both demonstrated the novelty of photography and forecast many later debates on its technology and aesthetics.The Birth of the Idea of Photography has been enriched with more than fifty photographs, reproduced in color, from North American and European collections. This edition also features a new preface by the author
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

Dedalus à Paris.
No full textInternational audienceComment comprendre le retour de Dedalus à Dublin, après son séjour parisien, dans Ulysses ? Plutôt qu’un échec, c’est une expérience à plusieurs facettes. D’un côté, sa translation à Paris montre une résistance aux jeux anglais/irlandais, Londres/Dublin, dominateur/dominé, que les écrivains irlandais ne pouvaient ignorer. D’un autre, son retour de Paris s’insère comme une étape dans sa quête d’une identité linguistique, culturelle et politique pour l’âme irlandaise sous l’emprise britannique. Et il s’agit bien de retour, car le français dans le texte revient dans ses souvenirs, les bribes de français remontent à la surface, remontent le temps, et re-montent—comme dans un travail de montage—la langue. Que fait Paris dans Ulysses ? Dans cette œuvre parsemée de souvenirs et de phrases « parisiens », Paris a plusieurs visages, clichés tirés des expériences de l’auteur avec le chic et l’exotique européens. Paris écrit, il trace, il dit et fait dire plusieurs choses, il hante. La langue chez Joyce semble dire, comme le narrateur dans Nadja d’André Breton, « Dis-moi qui tu hantes, je te dirai qui tu es ». Si Joyce explore les stéréotypes, c’est pour montrer que le français a déjà envahi la langue anglaise, comme autant de fragments de culture et de langue échoués sur les rivages de la langue anglaise
