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
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.

New physical interactions for mobile devices
No full textSoixante pour cent de la population mondiale possède aujourd'hui un téléphone portable. Les modèles récents, qui tendent à devenir de petits ordinateurs portables, sont jusqu’à 10 000 fois plus puissants et 300 000 fois moins lourds que le premier ordinateur, apparu voici 60 ans. Malgré cette puissance, et les ressources offertes par les équipements dont ils sont munis (écran tactile multitouch, accéléromètres et autres capteurs...), les mobiles souffrent de certaines limitations du fait de la disparition de nombreux périphériques d'entrée classiques tels que le clavier et la souris. Afin d'augmenter la bande passante interactionnelle de ces dispositifs et de tirer partie de ces capteurs, nous nous sommes intéressé dans cette thèse aux possibilités offertes par l'interaction gestuelle en considérant deux axes de recherche : les mouvements sur le mobile et les mouvements du mobile. Après avoir proposé un espace de classification nous avons conçu et développé plusieurs techniques d'interaction gestuelle destinées à enrichir et faciliter l'interaction de l'utilisateur avec ces dispositifs.Concernant les mouvements sur le mobile, nous nous sommes intéressé à l'amélioration du Flick, une technique de défilement largement popularisée ces dernières années. Après avoir étudié son ‘anatomie’, nous avons proposé d'exploiter plusieurs ressources interactionnelles jusqu'à présent inutilisées. Ce travail a donné naissance à trois nouvelles techniques: Flick-and-brake et LongFlick, qui utilisent respectivement la pression sur l'écran et les caractéristiques du geste de lancer pour mieux contrôler le défilement, et 'Semantic Flicking' qui exploite la sémantique du document pour faciliter la lecture. Dans un second temps nous avons considéré les possibilités offertes par l'interaction 3D, en déplaçant le dispositif mobile dans l'espace. Cette voie de recherche vise à permettre d'augmenter le vocabulaire d'interaction sans parasiter les interactions tactiles déjà existantes. Tirant parti des capteurs intégrés dans les mobiles, en particulier les accéléromètres, nous avons proposé deux nouvelles techniques d'interaction 3D : TimeTilt qui utilise des gestes fluides et impulsifs pour naviguer aisément entre différentes vues et JerkTilt qui introduit la notion de gestes 'auto-délimités' pour accéder rapidement à des commandes. Ces gestes auto-délimités ayant également la particularité de pouvoir être facilement combinés avec des interactions sur l'écran, nous avons enfin considéré la combinaison des modalités offertes par les gestes bi- et tri-dimensionnels.Sixty percent of the world's population now owns a mobile phone. Recent models, which tend to become small laptops are up to 10 000 times more powerful and 300 000 times less heavy than the first computer, appeared 60 years ago. Despite this power and all the resources provided by modern equipment (touchscreen, accelerometer and other sensors...), mobile phones suffer from certain limitations due to the lack of conventional input such as keyboard and mouse. To increase the interaction bandwidth of these device and take advantage of these sensors, we investigate the potential offered by gestural interaction by considering two lines of research: movements on the mobile and movements of the mobile. After defining a classification space we conceived and developed several gestural interaction techniques to enrich and facilitate interaction between the user and these devices. For the movements on the mobile we have proposed to improve the flick, a scrolling technique widely popularized in recent years. We first studied his ‘anatomy’ of this technique, then we proposed to exploit multiple interactional resources hitherto unused. This work gave birth to three new techniques: Flick-and-Brake and LongFlick, that respectively use the pressure on the screen and the characteristics of the throwing action to better control scrolling, and Semantic Flicking which leverage on document semantics to facilitate reading. In a second stage we considered the potential of 3D interaction, by moving the mobile device in the space. This line of research aims at expanding the interaction vocabulary while avoiding interferences with existing touch interactions. Leveraging on integrated sensors such as accelerometers, we proposed two new techniques for 3D interaction: TimeTilt, which uses smooth and impulsive gestures to easily navigate between different views, and JerkTilt, which introduced the notion of self-delimited gestures for accessing quickly to commands. An interesting property of these self-defined gestures is their ability to be combined with common interactions on the screen. We thus finally considered the combination of modalities offered by the two and three-dimensional gestures
