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
Growth and microdensity responses of multiple Douglas fir provenances to drought events in Southern France
No full textEngineering schoolForest plays an essential role with strong economic and ecologic values. However, these roles are threatened by the oncoming climate changes. Thus, a better comprehension and assessment of trees’ ability to survive in warmer and dryer climate but mostly to stronger drought event is important. Douglas fir (Pseudotsuga menziesii (Mirb.) Franco) is one of the most important planted trees in Europe and has a vast natural range. In its vast natural range Douglas fir faces various climates. Thus, understanding the variability of Douglas fir's responses within its natural range is a key to select well-adapted provenances for future plantations. Here, the response of Douglas fir coming from four regions is studied: Oregon, Washington, interior California and coastal California planted on two dry differing sites in 1992. The first site considered as the "dry" site is located in Corsica and the second considered as the "wet" site is located in the Gard. The response to drought events is studied using dendroecology and more specifically the resistance, recovery and resilience indices defined by Lloret on the 5 driest years of the dataset. The results show the importance of the testing site when studying drought responses. Similar drought response was obtained between all provenance regions on the moist site but not for the driest site where provenance coming from California showed highest radial growth resilience to the driest years. A trade-off between resistance and recovery is found for the ring width and the maximum density with differing strategies between Californian provenances and the others. Maximum density of the tree ring appears to be a strong marker of the drought events for all sites and provenance regions. As Californian provenances showed the highest overall growth for the dry site combined with the highest drought resilience, these provenances seem to be the most adapted for future plantation on dry sites. On moist site however with low drought risk, planting Californian provenances may result in unnecessary production loss compared to more productive Oregon or Washington provenances.La forêt joue un rôle essentiel à la fois économique et écologique mais ces rôles sont menacés par les changements climatiques. Une meilleure connaissance et compréhension des processus permettant aux arbres de survivre dans un climat plus chaud et plus sec mais surtout à des événements extrêmes est donc primordial. Le douglas (Pseudotsuga menziesii (Mirb.) Franco) qui possède une vaste aire naturelle a largement été planté en Europe. Dans sa vaste aire naturelle, le douglas est confronté à différents climats. La compréhension de la variabilité des réponses du douglas à ces contextes environnementaux dans son aire d’introduction est un enjeu clé afin de sélectionner les provenances les plus adaptées pour de futures plantations. Cette étude se concentre sur la réponse du douglas de quatre régions de provenance : Oregon, Washington, Californie intérieure et Californie côtière plantées sur deux sites en 1992. Le premier site, considéré comme le site “sec” se situe en Corse et le second, considéré comme le site “humide” se situe dans le Gard. La réaction aux évènements de sécheresse des arbres a été étudiée par dendroécologie en utilisant les indices de résistance, récupération et résilience de Lloret sur les 5 années les plus sèches de chaque site. Les résultats montrent l’importance de l’effet du site sur la réponse à la sécheresse. Sur le site humide, il y a peu de différence de résilience entre provenances sur les caractères étudiés alors que sur le site sec, les provenances Californienne ont eu une plus grande résilience de leur croissance radiale pour l’évènement le plus sec. Deux compromis entre la résistance et la récupération ont été trouvés entre la largeur de cerne et la densité maximale du cerne avec des stratégies différenciées entre les provenances Californiennes et les autres. La densité maximum du cerne apparait comme un très bon indicateur de la sécheresse pour les deux sites et quelle que soit la région de provenance. Les provenances Californiennes semblent les plus adaptées à des plantations sur site sec ou sur lesquels de la sécheresse est attendue car elles ont une meilleure résilience et croissance lors d’événements de sècheresse. En revanche pour les sites lesquels le risque de sécheresse est faible, la plantation de provenances Californiennes induit un sacrifice de production non justifiée par rapport aux provenances de l’Oregon ou du Washington
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.
