Some sensitive issues in the use and development of the anthropological theory of the didactic
Get PDFThis presentation repeats the opening lecture that the author gave on January 23, 2018 in Autrans (France) during the 6th International Congress on the ATD. Something of the oral form has been deliberately preserved in the text proposed here to the reader. As the title indicates, the aim was to draw attention to certain difficulties observed in the reception and use of the ATD. It is these difficulties that the structure of the text seeks to highlight and help overcome. After having underlined the question of the vocabulary specific to the ATD, we successively examine its theory of cognition, which is the basis of the ATD, then the cardinal notion of the possibly didactic, before moving on to the theory of praxeologies, which has undoubtedly received the greatest diffusion so far, and to progress by deepening the dialectic of persons and institutional positions, before specifying the concept of inquiry, which is at the heart of the current and future developments of the ATD
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
The mathematical needs of nonmathematicians : which institutional and social fate ? : studies in the didactic ecology and economy of mathematical knowledge
No full textCette recherche se situe dans le cadre de la théorie anthropologique du didactique (TAD) et a pour point de départ le constat d’une inégale diffusion des connaissances mathématiques opérationnelles dans les sociétés contemporaines. Au contraire des explications spontanées qui voient l’origine de ce phénomène dans une « propriété » des individus, dont beaucoup seraient rétifs, par nature ou par expérience, au « fait mathématique », cette recherche regarde de telles manifestations comme des symptômes individuels dont il s’agit d’étudier les causes à la lumière de la didactique entendue comme science des conditions et contraintes de tous niveaux déterminant la diffusion (et la non-diffusion) des connaissances. Les résultats obtenus permettent d’envisager une nouvelle définition du contrat gouvernant le rapport des personnes et des institutions à leurs besoins mathématiques.The framework of this research is the anthropological theory of the didactic (ATD). It takes as its starting point the uneven diffusion of a working knowledge of mathematics in contemporary societies. Unlike most spontaneous causal explanations in terms of “properties” of individuals, many of whom are thought to be averse to mathematics (either by nature or experience), this research construes such manifestations as individual symptoms to be interpreted in the field of didactics, regarded as the science of the conditions and constraints of all levels that determine the diffusion (and nondiffusion) of knowledge. The results arrived at allow us to contemplate the possibility of reconfiguring the relation of persons and institutions to their mathematical needs
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
