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
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.

Technical innovation in the making Drip irrigation in use in Morocco : actors, bricolages and efficiencies.
No full textPromue comme la technique d'irrigation en théorie la plus efficiente, et mise à contribution pour régler les grandes crises d'eau, le goutte à goutte se diffuse très rapidement de par le monde. La perspective d'une technique étudiée en station expérimentale, sans utilisateurs, et en définitive idéalisée, nous a d'emblée interpellé. Rejetant une vision normative du goutte à goutte (ce qu'il devrait être/faire), nous l'avons étudié en pratique, en interactions avec une multitude d'acteurs (ce qu'est le goutte à goutte et ce qu'il fait et pour qui). Notre objectif est d'analyser comment la pratique de cette innovation technique a changé la technologie et les trajectoires socioprofessionnelles des acteurs, et l'impact sur les efficiences d'irrigation. Nous montrons comment les acteurs locaux ont pris le contrôle de l'innovation, et des responsabilités dans des domaines que l'on pensait réservés aux ingénieurs dans la production, l'utilisation et la diffusion de l'innovation. Ces initiatives locales croisent et renforcent les programmes étatiques de développement du goutte à goutte. La technologie a séduit un grand nombre d'acteurs non-conventionnels qui ont changé la technologie, mais ont changé aussi eux-mêmes. La diffusion réussie du goutte à goutte assure leur promotion socioprofessionnelle, et à leur tour ils vont attirer d'autres utilisateurs dans le monde du goutte à goutte. C'est là où se résume la force du goutte à goutte comme objet technique autour duquel de puissants réseaux sociotechniques se sont construits. Le bricolage a permis la conception de systèmes plus adaptés aux conditions locales, mais aussi un apprentissage de la technique pour apprivoiser le changement. D'une technologie importée accessible à une minorité de grands agriculteurs, une pluralité de systèmes de goutte à goutte de proximité sont désormais accessibles au plus grand nombre. Enfin, les performances d'irrigation de ces systèmes sont hétérogènes, certains agriculteurs irriguant 3-4 fois plus que les volumes nécessaires aux besoins de la culture. Ces performances peuvent être expliquées par des pratiques d'irrigation favorisant le confort hydrique de la plante, traduisant ainsi les logiques des acteurs. Aujourd'hui, « l'économie d'eau » est un objectif irréalisable, qui n'est prioritaire pour aucun des acteurs, y compris l'Etat-promoteur. Nous concluons qu'il serait intéressant de mobiliser les acteurs non-conventionnels pour en faire des alliés pour intégrer le concept d'économie d'eau sur le terrain auprès des utilisateurs.Abstract Promoted as the most efficient irrigation technology, able to contribute to solving the major current water crises, drip irrigation spreads quickly throughout the world. The perspective of an idealized technology with a theoretical efficiency studied in experimental stations without users struck us immediately. Rejecting a normative view of drip irrigation (what it should be/do), we studied it in practice, interacting with a multitude of actors focusing on what it does and for whom. Our objective is to analyse how the practice of this technical innovation has changed the technology and the socio-professional pathways of different actors involved in drip irrigation, and analyse the impact on actual irrigation efficiencies. We show how local actors took control of the innovation taking responsibility in spheres once thought reserved for engineers in the production, use and dissemination of innovation. These local initiatives crossed and strengthened state development programs promoting drip irrigation. The technology attracted a large number of non-conventional actors who changed the technology, but also changed themselves. The successful diffusion of drip irrigation ensures their socio-professional promotion, and they in turn will attract more users to the world of drip irrigation. This constitutes the strength of drip irrigation, which is a technical object around which powerful socio-technical networks were built. Bricolage helped design systems better suited to local conditions, but was also a learning process to incorporate change. From an imported technology accessible to a minority of large farmers, a plurality of drip systems is now accessible for a wide diversity of farmers. Finally, the performance of irrigation systems is heterogeneous, some farmers irrigating 3-4 times the volume necessary for crop water requirements. This performance can be explained by irrigation practices favouring a water comfort to crops, reflecting the logic of the actors. Today, "water saving" is an unattainable goal, as it is not a priority for any of the actors, including the state. We conclude that it would be interesting to engage non-conventional actors as allies in order to promote the concept of water saving on the field with users
