As part of its seminar, Centre Arcadie will be pleased to welcome Jeanne Etelain for a session devoted to her book Zones. Terre, sexes et science-fiction, Flammarion, 2025.Jeanne Etelain, PhD from New York University and Université Paris-Nanterre, teaches philosophy and contemporary theory at the École supérieure des Beaux-Arts de Montpellier.After a presentation of the book, Igor Krtolica will be interviewed by Jean-Baptiste Vuillerod and Thibault De Meyer.After a presentation of the book, Jeanne Etelain will be interviewed by Ludovic Dubois, Nathalie Grandjean and Sébastien Laoureux.Free admission. Welcome to all.Book presentation Zone: this ubiquitous term nevertheless remains elusive. In a stunning conceptual investigation at the crossroads of geography, psychoanalysis and science fiction, Jeanne Etelain explores how "zone" has become central to understanding space, in the contemporary context of a crisis in the planet's conditions of habitability. The zone thus emerges as a spatial modality that defies habitual categories, confronting us with space's power to act, whether it's nature, the Earth or the body. All Centre Arcadie activities

Conference organized by Centre Arcadie and the Department of Philosophy as part of the "Philosophie du cinéma" course and the "Cultures et pensées cinématographiques" Specialization Master's degree.Dork Zabunyan is Professor of Film Studies at Université Paris 8 Vincennes-Saint-Denis. His publications include Les Cinémas de Gilles Deleuze (Bayard, 2011), L'Insistance des luttes - Images, soulèvements, contre-révolutions (De l'incidence éditeur, 2016), Foucault va au cinéma (Bayard, 2011) with Patrice Maniglier, Jacques Rancière et le monde des images(Mimesis, 2023).In 2020 he published Fictions of Trump. Puissances des images et exercices du pouvoir(Le point du jour). In this conference, the aim will be to take up this work in the context of Trump's second term.Presentation of the workDonald Trump's body is almost everywhere, outside us, on our screens, caught up in information channels that disseminate still and moving images of him. He is also present within us, more or less floating, in the minds of his detractors and supporters alike. The 45th President of the United States of America is not, however, the book's only subject. Based on his countless audiovisual representations, both before and after his election, the aim here is to explore the function of images in the exercise of power today, the stories they tell and the discourses they condition. Two questions run through this essay: what is this strange love of power, conveyed by images of an authoritarian leader, to which individuals who have no interest in voting for him adhere? What filmic counter-fires, real or imagined, are likely to mobilize the powers of images to evade this power, or even to thwart it? All Centre Arcadie activities

Conceptual field theory and didactic situation theory Two complementary theories for thinking about and organizing mathematical learningIn the first part of this talk, I'll propose an introductory situation in literal arithmetic (Barallobres & Giroux, 2008) that will enable me to introduce and illustrate the main concepts and methodological tools of the theory of didactic situations developed by Guy Brousseau (Brousseau, 1997; Bessot, 2024). In the second part, I will give a brief presentation of Gérard Vergnaud's theory of conceptual fields (Vergnaud, 1990; Durand-Guerrier and Saby, 2023), then show how this theory helps to shed further light on the introductory situation.The contributions of the anthropological theory of didactics The Anthropological Theory of Didactics (TAD, Chevallard, 2001) aims to explain why and how a given knowledge lives in a certain institution, and/or is transformed as it passes from one institution to another. This perspective and some of its evolutions will be presented and illustrated in this talk.Students' activities and teachers' practices in the mathematics classroom: analysis methodology with Activity TheoryIn this talk, we will present the founding assumptions of the Activity Theory framework adapted to the Didactics of Mathematics (TADM, Vandebrouck, 2008), showing how this theory gives importance to fine-grained analyses of mathematical knowledge to appreciate classroom developments. We will then exemplify some of these aspects on the teaching of limits at university (Bridoux and Grenier-Boley, 2024).BibliographyBarallobres, G., & Giroux, J. (2008).

Decarboxylation has become a key chemical transformation and has been widely reported in organic chemistry except for carbohydrates. This reaction can be catalyzed by transition metal and can also be induced by light, thermal activation, or photocatalysis. Borylated compounds have stimulated the pharmaceutical industry's interest (Boromycin, Bortezomib or boron neutron capture therapy). Recent methodologies have been developed to transform carboxylic acids to boronate esters by metal-catalyzed or light-promoted or photocatalyzed reactions. In this thesis, we explored the synthesis of borylated carbohydrates through a decarboxylation pathway. More specifically, sialic acids being among the most important carbohydrates in glycobiology, we addressed the problem of the synthesis of borylated sialic acids. On the other hand, organophosphates play an important role in diverse fields: in materials chemistry, in agriculture, in organic chemistry, and in biochemistry. Phosphorylation is a key reaction in biological processes such as signal transduction and cell activity regulation. The formation of phosphorylated carbohydrates has been widely described through two-electron mechanisms. However, radical phosphorylation of carbohydrates remains unexplored. This Ph.D. thesis describes the development of new methodologies for the decarboxylative functionalization of carbohydrates, focusing on borylation and phosphorylation..

The success of female Cistercian monasticism in the Southern Netherlands in the 13th century - over forty houses in the dioceses of Liège and Cambrai - is a powerful indicator of the aspirations of a society in transformation, enthusiastic about new forms of spirituality and religious life. For all that, the phenomenon remains surprisingly little studied, despite the wealth of archaeological and historical sources.
