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

La réalité virtuelle pour les besoins de l'industrie du bâtiment : guider la conception des interactions utilisateurs grâce à une méthodologie centrée sur les tâches
No full textThe field of virtual reality (VR) has undergone significant development these last years due to the growing maturity of this technology. This has allowed for its diffusion in many domains, notably in the building construction one. However, a problem resulting from such use of VR is that the VR interactions provided to the users are often not sufficiently adapted to their needs. It is indeed difficult to make a synthesis between the building trades’ expertise and the VR expertise. A research question then arises, which is how to allow the experts in a specific field, who do not have VR expertise, to be able to define and obtain the specifications of VR interaction technique, in autonomy. To answer this question, in this research we propose a new task-oriented methodology for the design of VR interactions. This one contains semi-automated systems that allow for the decomposition of the user task and for the determination of proposals of VR interaction techniques - i.e. the obtaining of the two types of specifications that are expected here. This methodology has been tested and evaluated on two case studies from the building sector. The results obtained show that our methodology can be used by experts from the construction industry, in autonomy, and that they have obtained specifications similar to the ones obtained by following a traditional user-centred design methodology.Le domaine de la réalité virtuelle (RV) a connu un développement important ces dernières années en raison de la maturité croissante de cette technologie. Cela a permis sa diffusion dans de nombreux domaines, notamment dans celui du bâtiment. Cependant, un problème résultant de l’utilisation de la RV dans ce domaine est que les interactions de RV fournies aux utilisateurs ne sont souvent pas suffisamment adaptées à leurs besoins. Il est en effet difficile de faire une synthèse entre l’expertise des métiers du bâtiment et l’expertise de la RV. Une question de recherche se pose alors qui est de savoir comment offrir la possibilité aux experts d’un domaine spécifique, qui n’ont pas d’expertise en RV, d’arriver à définir et obtenir les spécifications des techniques d’interaction de RV, et ce de manière autonome. Pour répondre à cette question, nous proposons dans cette recherche une nouvelle méthodologie centrée sur les tâches, pour la conception des interactions de RV. Celle-ci contient des systèmes semi-automatiques qui permettent la décomposition de la tâche utilisateur et la détermination de propositions de techniques d’interaction - i.e. l’obtention des deux types de spécifications attendus. Cette méthodologie a été testée et évaluée sur deux cas d’étude du secteur du bâtiment. Les résultats obtenus montrent que notre méthodologie est utilisable par des experts du bâtiment, en autonomie, et qu’ils ont obtenu des spécifications similaires `a celles qui sont obtenues en suivant une méthodologie traditionnelle de design centrée sur l’utilisateur
