Cuestiones epistemolĂłgicas y estudios de caso
En un paĂs -Francia- donde el campo del teatro estĂĄ estructurado culturalmente durante dĂ©cadas, el Teatro Aplicado es una nociĂłn que a menudo aparece como ancillar, frente a un arte institucionali-zado, incluso mirificado. Por un lado, estarĂa el Teatro, puro, noble, autĂ©ntico y por otro, estarĂan sus avatares: el teatro de empresa, el teatro para el desarrollo personal, el teatro para patologĂas, etc. Si tienen la misma fuente, su consanguinidad no deja de asustar. ÂżcĂłmo pueden unos artistas que crean alejados de cualquier coacciĂłn exterior pertenecer a la misma familia del teatro que unos actores o directores que "obedecen" a un encargo, en un contexto especĂfico, con un pĂșblico muchas veces participantes de talleres ... y que son por tanto prisioneros, en cierto modo, de un arte instru-mental izado? A este problema Ă©tico, este libro intenta responder, a travĂ©s de ejemplos concretos, para una mayor comprensiĂłn inrerculrural Francia/ Colombia.In a country -France- where the field of theater has been culturally structured for decades, Applied Theater is a notion that often appears as an ancillary, in the face of an institutionalized, even mirified, art. On the one hand, there would be the Theater, pure, noble, authentic and on the other, there would be its ups and downs: company theater, theater for personal development, theater for pathologies, etc. If they have the same source, their consanguinity does not stop frightening. How can some artists who create far from any external coercion belong to the same theater family as some actors or directors who "obey" a commission, in a specific context, with an audience that is often workshop participants... are they therefore prisoners, in a certain way, of an instrumented art? To this ethical problem, this book tries to respond, through concrete examples, for a greater intercultural understanding France/ Colombia.Bogot
Du calcul réfléchi à la multiplication posée
Lâobservation de difficultĂ©s dâĂ©lĂšves de cycle 3 dans la rĂ©alisation de lâalgorithme de la multiplication posĂ©e amĂšne Ă se demander quel continuum existe entre calcul rĂ©flĂ©chi et techniques opĂ©ratoires. Dans quelle mesure les Ă©lĂšves de cycle 3 font-ils appel au calcul rĂ©flĂ©chi dans la rĂ©alisation de la multiplication posĂ©e? Les programmes prĂ©conisent lâĂ©tablissement dâun lien Ă©troit entre apprentissage des techniques opĂ©ratoires, propriĂ©tĂ©s et sens des opĂ©rations. Ce travail sur le sens et les propriĂ©tĂ©s passe par la pratique du calcul rĂ©flĂ©chi. Instaurer des allers-retours entre technique automatisĂ©e et pratique rĂ©flĂ©chie semble indispensable, or lâapprentissage de la multiplication posĂ©e emprunte une direction : du calcul rĂ©flĂ©chi vers lâopĂ©ration posĂ©e. Notre protocole propose dâemprunter la direction inverse : partir dâune rĂ©alisation automatique, pour parvenir Ă une approche plus rĂ©flĂ©chie en imposant de la nĂ©cessitĂ© de reconnaĂźtre les calculs intermĂ©diaires. LâexpĂ©rimentation a permis de montrer comment des Ă©lĂšves de cycle 3 pouvaient passer d'une mĂ©thode automatique apprise en classe, dont le sens a Ă©tĂ© perdu de vue, Ă un travail faisant appel Ă une rĂ©flexion retrouvĂ©e sur le sens

This is a series of lectures on Bishop--Gromov's type inequalities adapted to metric spaces. We consider the case of Gromov-hyperbolic spaces and draw consequences of these inequalities such as compactness and finiteness Theorems. This course is intended to be elementary in the sense that the necessary background is described in detail

: Ăcole dâĂ©tĂ© 2021 - Contraintes de courbures et espaces mĂ©triques
The purpose of this course is to introduce the synthetic treatment of sectional curvature upper-bound on metric spaces. The basic idea of A.D. Alexandrov was to characterize the curvature bounds on the sectional curvature of a Riemannian manifold in term of properties of its distance function, and then to consider metric spaces with these properties. This approach turned out to be very fruitful and it found many applications, bringing geometric ideas to other settings.In this course we will introduce the metric spaces with a curvature upper-bound in the sense of Alexandrov, and derive some of their geometric properties. The subject is very vast and it is not possible to be exhaustive in the limited time of this course. We will concentrate on some properties, both local and global, emphasizing that these metric spaces share many properties with manifolds of bounded curvature
