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
Repenser la notion d'affordance dans ses dynamiques sémiotiques
No full textInternational audienceRethinking the Notion of Affordance in its Semiotic Dynamics. As far as semiotic and cognitive theories are concerned, new digital texts and objects emphasize the need to refocus on the intimate connection between user and his environment, considered as a space where cognition emerges, is deployed and manipulated through repeated interactions between subject's body and the technological and cultural world which surrounds him. In this case, the concept of "affordance" assumes a more central importance. Originally developed in the framework of the Gestalt theory, the notion of Aufforderungscharackter was subsequently reworked and made famous through the notion of affordance integrated in the ecological approach to visual perception conceived by James Gibson. However, the concept has successively been integrated into a more binary conception of cognition, which seems to be responsible for the loss of much of its heuristic power. I intend to go back here to the genesis of the notion and propose a semiotic and dynamic reinterpretation of this concept, where affordances can be seen as dispositions to act and patterns of expectation that are, from the beginning, intrinsically linked to the social and cultural dimensions of the human world. I will show how semiotic activity cannot take place in an infinitely brief present-time, but needs to be comprehended into a more systemic approach to cognition, where the environment and the subject cannot be considered on the basis of a binary distinction, and where an intrinsically cultural microgenetic activity of perception and cognition is seen as necessary for the emergence of possibilities of action in material and digital objects. In this context, affordances may be explained as responses to a conceivable practical action made possible by habits that subjects consider on the basis of their inclusion into a system of practices and knowledge which foreshadows a specific and situated horizon of action.Les nouveaux textes et objets numériques demandent aux théories sémiotiques et cognitives d'abandonner les approches structuralistes et computationnelles pour se recentrer sur le couplage intime formé par les usagers et leur environnement d'interaction, ce dernier considéré comme un espace permettant l'émergence, le déploiement et la manipulation d'une activité cognitive qui ne peut pas exister en dehors des interactions répétées établies entre le corps du sujet et le monde technologique et culturel l'entourant. Dans ces conditions la notion d'affordance assume une nouvelle centralité. Développée en partant de thématiques propres à la tradition gestaltiste, cette notion a été par la suite rendue célèbre par James Gibson qui en a fait un des piliers théoriques de son approche écologique à la perception visuelle. Malgré cela, ce concept a été par la suite intégré à des conceptions bien plus binaires de la cognition, qui semblent aujourd'hui responsables de la perte d'une grande partie de son pouvoir heuristique. L'objectif de cet article est de revenir à l'origine de cette notion et d'en proposer une relecture dynamique et sémiotique nous permettant de comprendre les affordances comme des dispositions à agir, comme des horizons d'attente étant, dès le début, intrinsèquement liés à la dimension sociale et culturelle du monde humain. Nous montrerons comment l'émergence des possibilités d'interaction avec les objets, et plus généralement comment toute activité sémiotique, ne peut pas se développer dans un temps ponctuel. Elle nécessite, au contraire, d'être comprise dans la continuité propre à une approche systémique à la cognition, permettant de prendre en compte l'environnement et le sujet en dehors d'une distinction binaire et nécessitant en même temps une émergence des activités cognitives et perceptives intégrant des dimensions culturelles et sociales fondamentales. Dans ce cadre, les affordances, peuvent être vues comme des structures émergentes, des réponses concevables à des actions pratiques rendues possibles par les habitudes cognitives retenues par les sujets sur la base de leur inclusion dans un système de pratiques et de connaissances qui présuppose un horizon d'action située et spécifique
