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
Conception et combinaisons de techniques d'interaction mid-air dans les environnements à grands écrans
No full textLarge display environments (LDEs) are interactive physical workspaces featuring one or more static large displays as well as rich interaction capabilities, and are meant to visualize and manipulate very large datasets. Research about mid-air interactions in such environments has emerged over the past decade, and a number of interaction techniques are now available for most elementary tasks such as pointing, navigating and command selection. However these techniques are often designed and evaluated separately on specific platforms and for specific use-cases or operationalizations, which makes it hard to choose, compare and combine them.In this dissertation I propose a framework and a set of guidelines for analyzing and combining the input and output channels available in LDEs. I analyze the characteristics of LDEs in terms of (1) visual output and how it affects usability and collaboration and (2) input channels and how to combine them in rich sets of mid-air interaction techniques. These analyses lead to four design requirements intended to ensure that a set of interaction techniques can be used (i) at a distance, (ii) together with other interaction techniques and (iii) when collaborating with other users. In accordance with these requirements, I designed and evaluated a set of mid-air interaction techniques for panning and zooming, for invoking commands while pointing and for performing difficult pointing tasks with limited input requirements. For the latter I also developed two methods, one for calibrating high-precision techniques with two levels of precision and one for tuning velocity-based transfer functions. Finally, I introduce two higher-level design considerations for combining interaction techniques in input-constrained environments. Designers should take into account (1) the trade-off between minimizing limb usage and performing actions in parallel that affects overall performance, and (2) the decision and adaptation costs incurred by changing the resolution function of a pointing technique during a pointing task.Les environnements à grands écrans (Large Display Environments, LDE) sont des espaces de travail interactifs contenant un ou plusieurs grands écrans fixes et divers dispositifs d'entrée ayant pour but de permettre la visualisation et la manipulation de très grands jeux de données. La recherche s'est de plus en plus intéressée à ces environnements durant ces dix dernières années, et il existe d'ores-et-déjà un certain nombre de techniques d'interaction correspondant à la plupart des tâches élémentaires comme le pointage, la navigation et la sélection de commandes. Cependant, ces techniques sont souvent conçues et évaluées séparément, dans des environnements et des cas d'utilisations spécifiques. Il est donc difficile de les comparer et de les combiner.Dans ce manuscrit, je propose un ensemble de guides pour l'analyse et la combinaison des canaux d'entrée et de sortie disponibles dans les LDEs. Je présente d'abord une étude de leurs caractéristiques selon deux axes: (1) le retour visuel, et la manière dont il affecte l'utilisabilité des techniques d'interaction et la collaboration co-localisée, et (2) les canaux d'entrée, et comment les combiner en d'efficaces ensembles de techniques d'interaction. Grâce à ces analyses, j'ai développé quatre pré-requis de conception destinés à assurer que des techniques d'interaction peuvent être utilisées (i) à distance, (ii) en même temps que d'autres techniques et (iii) avec d'autres utilisateurs. Suivant ces pré-requis, j'ai conçu et évalué un ensemble de techniques de navigation, d'invocation de commandes tout en pointant, et de pointage haute-précision avec des moyens d'entrée limités. J'ai également développé deux méthodes de calibration de techniques de pointage, l'une spécifique aux techniques ayant deux niveaux de précision et l'autre adaptée aux fonctions d'accélération. En conclusion, j'introduis deux considérations de plus haut niveau sur la combinaison de techniques d'interaction dans des environnements aux canaux d'entrée limités : (1) il existe un compromis entre le fait de minimiser l'utilisation des membres de l'utilisateur et celui d'effectuer des actions en parallèle qui affecte les performances de l'ensemble ; (2) changer la fonction de transfert d'une technique de pointage durant son utilisation peut avoir un effet négatif sur les performances
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
