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
Conduits périodiques et localement résonants pour le contrôle des ondes vibratoires en contexte industriel
No full textThe control of structural vibrations is a recurrent topic in industry. The automotive industry is no exception, as vibration and acoustic comfort are not only a selling point but also a legislative constraint. An automobile, whether thermally or electrically driven, has to deal with significant vibration problems. The system can be represented by three elements: a vibration source (e.g., engine or pump), a waveguide (e.g., fuel line, power cable), and a radiating element (e.g., firewall or fuel rail). In this work, the focus is on the waveguide and how to transform it so that it prevents source vibrations from reaching the radiating element. This work explores the effects of vibration attenuation and absorption enabled by the design of a phononic crystal based multi-wave vibration filter and the design of local resonator based 1D multi-wave vibration filters and absorbers. Phononic crystals are used to achieve filtering effects with band gap achievement. Local resonators are used to obtain attenuation or vibration absorption effects. The applicative potential of this type of system in the automotive context is then discussed around the effects related to the curvature of a waveguide, its coupling with a radiating plate and finally the influence of a heavy fluid in a periodic waveguide.Through this thesis, analytical models, numerical simulations and experiments are used to validate the physical behavior of the presented systems. This allows to propose designs to control the vibratory propagation in a waveguide.La maîtrise des vibrations structurelles est un sujet récurrent dans l'industrie. Le contexte de l'industrie automobile ne fait pas exception, car les vibrations et le confort acoustique ne sont pas seulement un argument de vente mais aussi une contrainte législative. Une automobile, qu'elle soit à propulsion thermique ou électrique, doit faire face à d'importants problèmes de vibrations.Le système peut être représenté par trois éléments : une source de vibrations (par exemple, un moteur ou une pompe), un guide d'ondes (une conduite de carburant, un câble d'alimentation) et un élément rayonnant (une cloison pare-feu, une rail d'injection). Dans ce travail, l'accent est mis sur le guide d'ondes et sur la manière de le transformer pour qu'il empêche les vibrations de la source d'atteindre l'élément rayonnant. Ce travail explore les effets de l'atténuation et de l'absorption des vibrations permises par la conception d'un filtre de vibrations multi-ondes basé sur un cristal phononique et la conception de filtres et d'absorbeurs de vibrations multi-ondes 1D basés sur des résonateurs locaux. Les cristaux phononiques permettent d'obtenir des effets de filtrage avec l'obtention de la bande interdite. Les résonateurs locaux sont utilisés pour obtenir des effets d'atténuation ou d'absorption vibratoire. Le potentiel applicatif de ce type de système dans le contexte automobile est ensuite discuté autour des effets liés à la courbure d'un guide d'ondes, à son couplage avec une plaque rayonnante et enfin à l'influence d'un fluide lourd dans un guide d'ondes périodique. A travers cette thèse, des modèles analytiques, des simulations numériques et des expériences sont utilisés pour valider le comportement physique des systèmes présentés. Ceci permet de proposer des conceptions pour contrôler la propagation vibratoire dans un guide d'ondes
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.
