A role for peroxisome proliferator-activated receptor gamma in resveratrol-induced colon cancer cell apoptosis.

2014

Scope Resveratrol may function as a chemopreventive agent. A recent clinical study demonstrates a reduction in tumor cell proliferation in colorectal patients receiving repeated oral ingestion of resveratrol. However, gaps remain in our knowledge of the molecular mechanisms by which resveratrol exerts its chemopreventive effect. We have previously demonstrated that resveratrol induces apoptosis in colon cancer cells and that resveratrol can sensitize chemoresistant colon cancer cells to various drugs. Based on its ability to activate peroxisome proliferator-activated receptor gamma (PPARγ) in colon cancer cells, we sought to determine the implication of this nuclear transcription factor in …

La politisation de l'ordinaire : Enjeux et limites de la mobilisation numérique

2015

This article examines the politicization processes of ordinary digital practices as well as its role in the constitution of new protester groups. Its interest is also represented by the construction of an original theoretical framework aiming to underline the complementarity between different theoretical perspectives. By encouraging a connection between the sociology of social movements, the critical Theory and the studies of “information practices”, the author elaborates a new approach to mobilisation focused on the emergence of a more and more citizen's engaged position with regard to the “information world” and not only based on militant uses of the media. While claiming a critical appro…

Les représentations du livre numérique chez les professionnels de l’information-documentation

2014

L’émergence du livre numérique dans le paysage culturel français contribue à progressivement redessiner nombre de pratiques professionnelles. Parmi les sphères professionnelles directement concernées, celle de l’information-documentation occupe une place particulière. Nous présentons ici le résultat de travaux de recherche menés auprès de professionnels, bibliothécaires ou enseignants documentalistes, usagers ou non-usagers de dispositifs de lecture numérique, afin de questionner leurs représentations du livre numérique ainsi que leurs perceptions des évolutions futures de leurs métiers.

Les Français, mauvais élèves de la classe de langues ? : De la communication pour sortir du mythe

2006

16 pages; Issu d'une réflexion pédagogique, nourrie d'une théorisation de la communication interpersonnelle, cet article attribue le mythe des difficultés des Français à apprendre des langues étrangères à une angoisse liée à leur représentation culturelle de la langue française. L'article montre comment, grâce à une prise en compte des identités et à une focalisation sur la compétence de communication (Hymes), des étudiants français peuvent être amenés à communiquer de manière spontanée et à assumer leur niveau, forcément imparfait, dans une langue étrangère.

La convivialité en entreprise. Topique et topographie d'une figure sensible.

2009

International audience; D'abord marquée par l'isotopie de la table, le partage alimentaire et le plaisir de manger, la convivialité s'est progressivement émancipée de cet espace symbolique pour investir d'autres lieux : la vie en société, les relations interpersonnelles, le monde des objets. Dans son pouvoir d'extension, cette valeur a pris, au sein des organisations, de multiples traits de manifestation, des signes les plus discrets de politesse aux événements les plus fastueux. Au-delà, c'est tout le déploiement figuratif de la convivialité, la conversion de cette valeur en figure sensible, qui en dessine les contours symboliques au coeur des organisations.

Design in education and training

2019

Based on interviews with innovative companies in the education and training sector, this article studies the processes by which these companies innovate. The observations focus on the positioning of innovative companies in the field of education, the constraints that structure them, the processes implemented in the deployment of services and products, and the organization of communication on design. The results of the lexicometric analysis contribute to describing an episteme of contemporary design that both structures and limits the work of designers. This episteme partly reverses the Taylorist episteme of industrial design while retaining some of its characteristics. In particular, the hu…

Design in education and training

2019

À partir d’entretiens réalisés auprès d’entreprises innovantes du secteur de l’éducation et de la formation, cet article étudie les processus par lesquels ces entreprises innovent. Les observations portent sur le positionnement des entreprises innovantes dans le champ de l’éducation, les contraintes qui les structurent, les processus mis en œuvre dans le déploiement des services et produits, et l’organisation de la communication sur le design. Les résultats de l’analyse lexicométrique contribuent à décrire une épistémè du design innovant qui à la fois structure et limite le travail des designers. Celle-ci renverse en partie l’épistémè tayloriste du design industriel tout en héritant de cert…

Multimodal Communication and Peer Interaction during Equation-Solving Sessions with and without Tangible Technologies

2023

Despite the increasing use of technologies in the classroom, there are concerns that technology-enhanced learning environments may hinder students’ communication and interaction. In this study, we investigated how tangible technologies can enhance students’ multimodal communication and interaction during equation-solving pair work compared to working without such technologies. A tangible app for learning equation solving was developed and tested in fourth and fifth-grade classrooms with two class teachers and 24 students. Video data of the interventions were analysed using deductive and inductive content analysis. Coded data were also quantified for quantitative analysis. Additionally, teac…

Extension du domaine du sacré

2013

Faisant le constat qu’il releve d’un monde aujourd’hui completement revolu, Paul Ricœur (1974 : 71) ecrivait : « Le sacre est l’archaique ». Demarche bien temeraire, donc, celle d’engager Questions de communication dans un debat referme sur le passe, voire depasse. La discussion serait close et le sujet entendu. Tournons la page. Pourtant le sacre reste d’une etonnante acuite. Il y a quelques annees, il trouvait encore a s’exposer dans ce temple de la creation moderne et de l’avant-garde qu’e...
