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
Energy transfers in the ice and surface Arctic ocean at inertial and sub-inertial frequencies
No full textThe effect of sea ice on inertial motion in the Arctic Ocean is analyzed using the MIT global circulation model (MITgcm). Inertial oscillations in the ice are found to be more important in low ice concentration areas. In these zones, ice drags the underlying ocean into circular motion, forming near-inertial waves in the ocean's mixed layer. At the base of the mixed layer, increased shear drives a deepening of the mixed layer and the strong stratification leads to a stronger vertical component of the near-inertial oscillations, creating internal gravity waves. When the ice concentration is high, the amplitude of inertial oscillations in the ice can be different between nearby locations (because of a spatially varying ice strength or wind). This results into divergent/convergent motion of the ice at the inertial frequency, which generates near-inertial oscillations with a strong vertical component, by alternating suction/pushing of the water. These two mechanisms produce inertial energy in the presence of ice. We find that the effects of sea ice on the generation of near-inertial oscillations are i) to reduce the amount of near-inertial waves in the surface ocean (by about 60%), and ii) to increase the generation of internal gravity waves (vertical component of near-inertial waves) in the winter, by the convergence/divergence mechanism outlined above. We also find that the generation of near-inertial motion is a local process, since no significant vertical and horizontal propagation of near-inertial energy is found.L'effet de la glace de mer sur les mouvements inertiels dans l'Océan Arctique est analys é à l'aide du modèle de circulation globale du MIT (MITgcm). On trouve de plus importantes oscillations inertielles dans la glace dans les zones faibles en glace. Dans ces zones, la glace entraîne l'océan sous-jacent dans des mouvements circulaires, générant des ondes inertielles dans la couche de mélange. À la base de la couche de mélange, le fort cisaillement entraîne un approfondissement de la couche et la forte stratification rend la composante verticale de l'oscillation inertielle plus forte, créant des ondes internes de gravité. Lorsque la concentration de glace est élevée, l'amplitude des oscillations inertielles dans la glace peut être différente entre zones voisines (à cause d'une force de glace ou d'un vent qui varie spatialement). Ceci résulte en un mouvement de convergence/divergence de la glace à la fréquence inertielle, ce qui génère des oscillations inertielles avec une forte composante verticale dans la couche de mélange par l'alternance de mouvements qui tirent/poussent l'eau verticalement. Il s'agit là des deux méchanismes contribuant à l'énergie inertielle de l'océan en présence de glace de mer. Les effets de la glace sont i) de réduire la quantité d'ondes inertielles latérales dans l'océan desurface (d'environ 60%) et ii) d'augmenter la génération d'ondes de gravité internes (composante vertical des oscillations inertielles) en hiver. La génération d'oscillations inertielles est un processus local, puisqu'aucune propagation importante d'énergie inertielle n'est observée
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.
