Interactions épistémiques médiatisées par ordinateur pour l’apprentissage des sciences
No full textThis paper reports on a five-year collaborative research programme, the aim of which was to create CSCL Environments that favour and support the production of epistemic interactions for the co-construction of scientific notions. The successive development of three systems (C-CHENE, CONNECT and DAMOCLES) enabled several research questions to be addressed, including : structuring the communication interface, statistically or automatically constituting dyads in order to favour conceptual confrontation, summarising points to be debated, and the teacher’s multiple roles. In conclusion, limitations of, and lessons learned from this research are discussed, notably : freedom and constraint in the communication interface, structuring overall collaborative problem-solving sequences, the richness and negotiability of environments, the interrelations between cognitive, epistemic and social dimensions of interaction, and the evolution of new educational practices.Nous présentons le bilan d’un programme de recherches à cinq ans concernant l’élaboration d’ Environnements Informatiques d’ Apprentissage Coopérant (EIAC) qui visent la co-construction de notions scientifiques dans et par les interactions épistémiques. Lors de l’élaboration successive de trois systèmes (C-CHENE, CONNECT et DAMOCLES), les questions de recherche suivantes ont été abordées : la structuration de l’interface de communication, la constitution des dyades (statistique ou combinatoire) afin de favoriser une confrontation conceptuelle, la présentation des points à débattre et les rôles multiples du professeur. Nous discutons des limites de notre recherche et apportons notre bilan concernant le degré de liberté et de contrainte dans l’interface de communication, l’organisation générale des séquences de résolution de problèmes, la richesse et la flexibilité des environnements, les interrelations entre les dimensions cognitive, épistémique et sociale de l’interaction et enfin l’évolution des pratiques éducatives.Baker Michael, De Vries Erica, Lund Kristine, Quignard Matthieu.

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
Ma guerre 1914-1918 di Charles Bruneau: parole di un linguista al fronte
No full textVersion française. Le chapitre original est en italien.International audienceThe French linguist Charles Bruneau (1883-1969) was 31 years old when the war was declared. He was assistant professor at the Faculté des Lettres in Nancy. He served as a radio soldier, receiving and translating german communication for the État-Major of the 132 e R.I. (24th brigade). Very early in his war experience, on May 6th 1915, he asked a former student Maurice Journé, 16 years old, to keep his correspondance until the end of the war, like a most reliable deposit of his war memory. Right after the war, Charles Bruneau collected all his writings (letters to his family, to Maurice and his war diary) and made a book called "My War 1914-1918". We present this unpublished book and some preliminary analyses based on textual statistics
