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
Qu'est-ce que programmer une interface adaptative ? Le cas du prototype de station sol pour drones du projet D3CoS
No full textNational audienceApparu dans les années 80, l'adaptation est un thème de recherche récurrent en informatique interactive. Il est aujourd'hui abordé par des communautés très hétérogènes et s'articule autour de problématiques très diverses : adaptation à l'utilisateur, adaptation à la plateforme d'exécution, adaptation à l'environnement physique, etc. Mais si de nombreux cadres conceptuels ont été élaborés, peu a été fait en direction des programmeurs de tels systèmes adaptatifs, ce qui rend leur tâche particulièrement difficile. Dans cet exposé nous montrerons que l'adaptation est en réalité une propriété relative au point de vue pris sur le système et que, du point de vue de la programmation, la majeure partie des scénarios d'adaptation peut se ramener à un patron d'architecture simple de programmation réactive. C'est en nous appuyant sur cette analyse que nous avons pu développer une application, dans le cadre du projet D3CoS, qui combine de manière simple et innovante interaction et adaptation. Nous en présenterons quelques aspects
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
Concepts and tool for interactive computing
No full textLes systèmes informatiques actuels au cœur des systèmes critiques, notamment le transport aérien, sont caractérisés par de multiples interactions, ou couplages forts, entre les opérateurs humains, les dispositifs physiques et les logiciels. La conception de ces systèmes nécessite de prêter attention aux relations causales entre les différents processus impliqués. Par conséquent, il ne s'agit plus de concevoir des systèmes d'entrée/sortie pour lesquels l'algorithme doit être créé, mais de spécifier des réseaux dynamiques de processus hétérogènes en interaction. En conséquence, ces systèmes informatiques ne peuvent plus être facilement appréhendés dans le cadre théorique classique : la théorie de la calculabilité, héritée des travaux de Turing et Church. Les événements asynchrones, les flux d'exécution indépendants, la création dynamique d'objets, ou encore les processus d'attente passive posent des difficultés spécifiques dans la modélisation et la pratique. L'objectif principal de cette thèse est d'examiner la possibilité d'un nouveau cadre théorique pour l'informatique interactive afin de mieux la caractériser, en suivant un programme de recherche qui vise à définir l'interaction. Sonder la question de l'interaction se situe à l'intersection entre l'interaction homme-machine et les pratiques de programmation impliquées, l'épistémologie de l'informatique et l'informatique théorique. Nous cherchons à expliquer ce qui rend possible l'interaction dans un système informatique, autrement dit nous nous interrogeons sur les mécanismes sous-jacents. Nous proposons le concept de modèle d'exécution pour construire une telle explication. Parmi les exigences, nous définissons la nécessité d'un composant que nous appelons un "orchestrateur causal''. La conséquence de cette réflexion épistémologique est de motiver, guidée par une étude auprès de programmeurs, une approche visant à outiller un langage dédié à l'interaction. A travers un ensemble de techniques d'interaction au sein d'un éditeur de code, Causette, nous proposons d'aider le programmeur à comprendre les relations causales d'un programme.Current computing systems at the heart of critical systems, especially air transport, are characterized by multiple interactions, or strong couplings, between human operators, physical devices, and software. The design of such systems requires attention to the causal relationships between the different processes involved. Therefore, the task is no longer about designing input/output systems for which the algorithm must be created but specifying dynamic networks of interacting heterogeneous processes. As a result, these computing systems can no longer be easily understood within the classical theoretical framework: computability theory, inherited from the work of Turing and Church. Asynchronous events, independent execution flows, dynamic object creation, or passive waiting processes pose specific difficulties in modeling and practice. The primary objective of this thesis is to examine the possibility of a new theoretical framework for interactive computing to characterize it better, following a research program that aims at defining interaction. Probing the question about interaction is at the intersection of Human-Computer Interaction and involved programming practices, the epistemology of computing, and theoretical computer science. We are looking for an explanation of how interactive computing comes about and what mechanisms support it. We propose the concept of an execution model to build such an explanation. Among the requirements, we define the necessity of a component that we call a "causal orchestrator''. The consequence of this reflection is to motivate, guided by a study with programmers, an approach to tool a language dedicated to interaction. Through a set of interaction techniques within a code editor, Causette, we propose a way to support the programmer in understanding causal relationships between processes described in interaction programs
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
