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
Développement de réseaux de communication pour la détection précoce de symptômes pathologiques
No full textThe objective of the thesis is to study and develop networks of sensors WBAN (Wireless Body Area Networks) consisting of monitoring patients remotely, detecting and preventing critical medical situations while reducing energy consumption. First, we studied the architecture and characteristics of WBAN networks and we identified the different candidate wireless technologies for these networks. Then, WBAN medical applications resulting from research work as well as medical sensors were presented. Secondly, we have interested to the LoRa technology, highlighted previously. We have proposed a low-energy medical application based on LoRa technology (named HeaLoRa) to determine and transmit the level of criticality of a patient to the medical center. Then, based on the spreading factor of the LoRa technology which provides a compromise between the energy consumption and the error probability, we proposed a selection method to choose the relevant spreading factor according to the critical state of a patient. Finally, for the experimental part, we have developed medical applications for the early detection of pathological symptoms of patientsL’objectif de la thèse est d’étudier et développer des réseaux de capteurs WBAN (Wireless Body Area Networks) consistant à surveiller les patients à distance, de détecter et de prévenir les situations médicales critiques tout en réduisant la consommation énergétique. Dans un premier temps, nous avons étudié l’architecture et les caractéristiques des réseaux WBAN et nous avons recensé les différentes technologies sans fil candidates pour ces réseaux. Puis, des applications médicales WBAN issues de travaux de recherche ainsi que des capteurs médicaux ont été présentés. Dans un second temps, nous nous sommes intéressés à la technologie LoRa, mise en évidence précédemment. Nous avons proposé une application médicale à faible consommation énergétique basée sur la technologie LoRa (nommée HeaLoRa) permettant de déterminer et de transmettre le niveau de criticité d’un patient au centre médical. Puis, nous basant sur le facteur d’étalement de la technologie LoRa qui fournit un compromis entre la consommation énergétique et la probabilité d’erreur, nous avons proposé une méthode de sélection pour choisir un facteur d’étalement pertinent suivant l’état critique d’un patient. Enfin, pour la partie expérimentale, nous avons développé des applications médicales pour la détection précoce des symptômes pathologiques des patient

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
