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
Flow fact automata for the expression and the integration of properties in WCET analysis
No full textDans le domaine des systèmes critiques, l'analyse des temps d'exécution des programmes est nécessaire pour planifier et ordonnancer au mieux différentes tâches et par extension pour dimensionner les systèmes. La durée d'exécution d'un programme dépend de divers facteurs comme ses entrées ou le matériel utilisé. Or cette variation temporelle pose problème dans les systèmes temps-réel dans lesquels il est nécessaire de dimensionner précisément les temps processeur alloués à chaque tâche, et pour cela, connaître leur temps d'exécution au pire cas. Au sein de l'équipe TRACES à l'IRIT, nous cherchons à calculer une borne supérieure à ce temps d'exécution au pire cas qui soit la plus précise possible. Pour cela, nous travaillons sur le graphe de flot de contrôle d'un programme qui représente un sur-ensemble des ses exécutions possibles, que nous accompagnons d'annotations sur des comportements spécifiques du programme susceptibles de réduire la sur-approximation de notre estimation. Dans les outils destinés au calcul du temps d'exécution au pire cas des programmes, les annotations sont habituellement exprimées et intégrées grâce à des langages d'annotation spécifiques. Nous proposons d'utiliser des automates appelés automates d'annotation de flot en lieu et place de ces langages, afin de fonder non seulement l'expression, mais également l'intégration d'annotations dans l'analyse sur des bases formelles. Nous présentons ces automates enrichis de contraintes, de variables et d'une hiérarchie et nous montrons comment ils supportent les divers types d'annotations utilisés dans le domaine de l'analyse du temps d'exécution au pire cas. Par ailleurs, l'intégration des annotations dans une analyse se fait habituellement par l'association de contraintes numériques au graphe de flot de contrôle. Les automates que nous présentons supportent cette méthode mais leur expressivité offre également de nouvelles possibilités d'intégration basées sur le dépliage du graphe de flot de contrôle. Nous présentons des résultats expérimentaux issus de la comparaison de ces deux méthodes qui montrent comment le dépliage de graphe peut améliorer la précision de l'analyse. A terme, ce gain de précision dans l'estimation du temps d'exécution au pire cas permettra de mieux exploiter le matériel sans faire courir de risques à l'utilisateur ou au système.In the domain of critical systems, the analysis of execution times of programs is needed to schedule various task at best and by extension to dimension the whole system. The execution time of a program depends on multiple factors such as entries of the program or the targeted hardware. Yet this time variation is an issue in real-time systems where the duration is required to allow correct processor time to each task, and in this purpose, we need to know their worst-case execution time. In the TRACES team at IRIT, we try to compute a safe upper bound of this worst-case execution time that would be as precise as possible. In order to do so, we work on the control flow graph of a program that represents an over-set of its possible executions and we combine this structure with annotations on specific behaviours of the program that might reduce the over-approximation of our estimation. Tools designed to compute worst-case execution times of programmes usually support the expression and the integration of annotations thanks to specific annotation languages. Our proposal is to replace these languages with a type of automata named flow fact automata so that not only the expression but also the integration of annotations in the analysis inherit from the formal basis of automata. Based on these automata enriched with constraints, variables and a hierarchy, we show how they support the various annotation types used in the worst-case execution time domain. Additionally, the integration of annotations in an analysis usually lead to associate numerical constraint to the control flow graph. The automata presented here support this method but their expressiveness offers new integration possibilities based on the partial unfolding of control flow graph. We present experimental results from the comparison of these two methods that show how the graph unfolding can improve the analysis precision. In the end, this precision gain in the worst-case execution time will ensure a better usage of the hardware as well as the absence of risks for the user or the system itself

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.
