Les formes de l’animation : variété et variations
No full textInternational audienceThis article explores the variety and variations of socio-cultural animation. It draws on theorisations of forms of education, particularly school education, to examine those of animation and popular education. It is based on an ethnographic fieldwork of a number of settings and analyses the configurations of the sequences offered to children from diffrent dimensions. It shows how these forms of animation are situated on a continuum between recreation and education.Cet article explore la variété et les variations des formes de l’animation socioculturelle. Il s’appuie sur les théorisations des formes de l’éducation, notamment scolaire, pour interroger celles de l’animation et de l’éducation populaire. Il repose sur une enquête ethnographique dans plusieurs accueils collectifs de mineurs et analyse les configurations des séquences proposées aux enfants selon plusieurs dimensions. Il montre ainsi comment ces formes de l’animation se situent sur un continuum entre récréation et éducation
ARCHIMEDE, THEON de SMYRNE et √3
No full textWe know that the algorithm of Theon of Smyrna (70-135 AD) made it possible to highlight fine frames of √2 by rationals. However, this same algorithm also applies to √3 and makes it possible to find the famous Archimedes inequalities:265/153 < √3 < 1351/780. An interesting question is whether this very simple iterative method exposed by Theon was not known to the Greeks before him, notably by Archimedes or his contemporaries. Knowing that Theon of Smyrna had already compiled previous works. Note that this algorithm had also made it possible to open a breach towards the Pell-Fermat equations and continued fractions.On sait que l’algorithme de Théon de Smyrne (70-135 ap JC) a permis de mettre en évidence des encadrements fins de √2 par des rationnels. Pourtant ce même algorithme s’applique aussi à √3 et permet de retrouver les fameuses inégalités d’Archimède :265/153 < √3 < 1351/780. Une question intéressante est de savoir si cette méthode itérative très simple exposée par Théon n’était pas connue des grecs avant lui, notamment par Archimède ou ses contemporains. Sachant que Théon de Smyrne avait déjà compilé des travaux antérieurs. Notons que cet algorithme avait permis aussi d’ouvrir une brèche vers les équation de Pell-Fermat et les fractions continues

No full textAuctorialité et fanfictions en ligne : disparition de l’auteur ou figure hybride
No full textInternational audienceThis article aims to examine how collaborative and contributive dynamics – key drivers in the production of fan writings such as online fanfiction – are concretely expressed in the activity of their authors. The analysis focuses on the mechanisms that facilitate connections between authors and their readership, in order to identify an underlying form of relational economy. Drawing on the concept of authoriality (Neeman, 2012), the article moves beyond questions of authority and ownership to explore other dynamics at play. The study of personal networks reveals how these dynamics emerge within interpersonal relationships. It relies on data collected from 71 participants through semi-structured interviews, as well as systematic gathering of reader comments, to refine the understanding of audience contribution. The purpose is to grasp the key factors shaping the production of these specific contents, such as fanfiction, while exploring whether the role of digital technologies leads to the disappearance of the author or the creation of a hybrid figure.Cet article propose d’examiner comment les dynamiques collaboratives et contributives, qui jouent un rôle clé dans la production des écrits de fans, tels que les fanfictions sur le Web, se manifestent concrètement dans l’activité de leurs auteurs et autrices. L’analyse se concentre sur les dispositifs qui facilitent la mise en relation des autrices/auteurs et de leur lectorat, afin d’identifier une forme d’économie relationnelle sous-jacente. S’appuyant sur le concept d’auctorialité (Neeman, 2012), l’article va au-delà des questions d’autorité et de propriété en explorant d’autres dynamiques en jeu. L’analyse des réseaux personnels révèle comment celles-ci se forment au sein de relations interpersonnelles. Il mobilise des données obtenues auprès de 71 personnes enquêtées lors d’entretiens semi-directifs, mais également des données issues d’un recueil systématique des commentaires reçus, afin d’affiner la compréhension de la contribution du lectorat. L’objectif est de comprendre les enjeux qui structurent la production de ces contenus spécifiques, tels que les fanfictions, tout en explorant si le rôle joué par le numérique conduit à une disparition de l’auteur ou à la création d’une figure hybride
Documenting the political divide : health crisis, government communication, and political legitimacy in Cameroon
No full textThe reception given to the various government measures to combat Covid-19 in the midst of the health crisis between 2021 and 2022 illustrates the political divide between the Cameroonian State and its population. This article analyzes the mechanisms behind this lack of trust, using a sociology of public action to combat Covid-19 and a sociology of the State. Our analysis highlights several structural elements that undermine the legitimacy of the Cameroonian State in the eyes of its population: centralist decision-making logics that resist any form of openness likely to give more room to the dialogue and consensus required by the health emergency; the instrumentalization of public action for presidential marketing purposes, and a great lack of flexibility and proximity in government communication. All this in a context of technological evolution (the weight of social networks) that calls for a rethinking of the content, form, channels and carriers of information and communication
Rendre compte de la fracture politique : crise sanitaire, communication gouvernementale et légitimité politique au Cameroun
No full textL'accueil réservé aux différentes mesures gouvernementales de lutte contre la Covid-19 en pleine crise sanitaire entre 2021 et 2022 illustre la fracture politique entre l'État camerounais et sa population.Cet article analyse les mécanismes de ce manque de confiance, à partir d'une sociologie de l'action publique de lutte contre le Covid-19 et d'une sociologie de l'État. Notre analyse fait ressortir plusieurs élémentsstructurels qui sapent la légitimité de l'État camerounais aux yeux de sa population : des logiques décisionnelles centralistes qui résistent à toute forme d'ouverture susceptible d'accorder plus de place au dialogue et auconsensus qu'exige l'urgence sanitaire ; l'instrumentalisation de l'action publique à des fins de marketing présidentiel, et un grand manque de flexibilité et de proximité dans la communication gouvernementale. Tout cecidans un contexte d'évolution technologique (le poids des réseaux sociaux) qui invite à repenser le contenu, la forme, les canaux et les porteurs de l'information et de la communication
MEFA: Multimodal Image Early Fusion with Attention Module for Pedestrian and Vehicle Detection
No full textInternational audiencePedestrian and vehicle detection represents a significant challenge in autonomous driving, particularly in adverse weather conditions. Multimodal image fusion addresses this challenge. This paper proposes a new early-fusion attention-based approach from visible, infrared, and LiDAR images, designated as MEFA (Multimodal image Early Fusion with Attention). In this study, we compare our MEFA proposal with a channel-wise concatenation early-fusion approach. When coupled with YOLOv8 or RT-DETRv1 for pedestrian and vehicle detection, our contribution is promising in adverse weather conditions (i.e. rainy days or foggy nights). Furthermore, our MEFA proposal demonstrated superior mAP accuracy on the DENSE dataset
Analysis of a toy model for optimal crop protection
No full textInternational audienceIn this paper we investigate an optimal control problem involving a toy model for theprotection on a crop field. Precisely, we consider a protection on a crop field and we wantto place intervention zones represented by a control, in order to maximize the protection onthe field during a given period. We prove that there exists a unique control which maximizesthe protection and, moreover, it must be a bang-bang control. Furthermore, with additionalassumptions on the crop field geometry, some results on the shape of the optimal interventionare proved using comparison results for elliptic equations via Schwarz and Steiner symmetrizations. Finally, some numerical simulations are performed in order to illustrate those results
