Bright Hot Impacts by Erupted Fragments Falling Back on the Sun: Magnetic Channelling
2016
Dense plasma fragments were observed to fall back on the solar surface by the Solar Dynamics Observatory after an eruption on 7 June 2011, producing strong EUV brightenings. Previous studies investigated impacts in regions of weak magnetic field. Here we model the $\sim~300$ km/s impact of fragments channelled by the magnetic field close to active regions. In the observations, the magnetic channel brightens before the fragment impact. We use a 3D-MHD model of spherical blobs downfalling in a magnetized atmosphere. The blob parameters are constrained from the observation. We run numerical simulations with different ambient density and magnetic field intensity. We compare the model emission i…
Do ventilatory parameters influence outcome in patients with severe acute respiratory infection? Secondary analysis of an international, multicentre1…
2021
Purpose: To investigate the possible association between ventilatory settings on the first day of invasive mechanical ventilation (IMV) and mortality in patients admitted to the intensive care unit (ICU) with severe acute respiratory infection (SARI). Materials and methods: In this pre-planned sub-study of a prospective, multicentre observational study, 441 patients with SARI who received controlled IMV during the ICU stay were included in the analysis. Results: ICU and hospital mortality rates were 23.1 and 28.1%, respectively. In multivariable analysis, tidal volume and respiratory rate on the first day of IMV were not associated with an increased risk of death; however, higher driving pr…
Age Differences in Learning from Instructional Animations
2015
Summary: The present study tests the effects of the decline of executive functions and spatial abilities with aging on the comprehension of a complex instructional animation. An animation of a piano mechanism was presented individually to 33 young adults and 31 elderly participants. Two presentation speeds of the animation (normal and slow) were compared in a 2×2 experimental design. Eye movements were recorded during the learning time. Then, four executive function tests (inhibition, shifting, updating, and processing speed) and a spatial ability test (differential aptitude test) were undertaken by each participant. Results showed that the comprehension of animations was significantly affe…
Can animation compensate for temporal processing difficulties in deaf people?
2020
International audience; This article addresses the issue of animation as an aid for temporal processing difficulties in deaf people learning the Highway Code. A decision‐making task involving static or animated road situations was performed by 21 deaf and 24 hearing participants. They were confronted with four types of driving situations (overtaking, negotiating roundabouts, highways, and intersections) and had to decide whether or not to proceed. Participants were presented with two different formats (static vs. animated) and two levels of difficulty (simple vs. complex). Results showed that deaf participants had poorer performances in the static condition than hearing participants. Perfor…
Animer le matériel d'apprentissage du code de la route pour une meilleure compréhension et réussite à l'examen
2016
29èmes Entretiens du Centre Jacques-Cartier. Facteurs humains, technologies embarquées et numériques : quel rôle pour les politiques de sécurité routière ?, LYON, FRANCE, 21-/11/2016 - 23/11/2016; Des travaux sur l'intérêt d'animer le matériel du code de la route pour des publics en difficulté linguistique sont présentés et discutés.
Rendre dynamique le matériel d'apprentissage du code de la route : un intérêt particulier pour les sourds
2017
Entretiens Jacques Cartier, QUEBEC, CANADA, 16-/10/2017 - 18/10/2017; ACOSUR : Accès au Code de la route et SURdité. Contexte : La réussite à l'examen du code de la route est un facteur facilitant l'insertion sociale et professionnelle. Avec un taux de réussite largement inférieur aux candidats entendants, les individus sourds éprouvent de nombreuses difficultés. Le matériel actuel composé d'images statiques ne serait pas compatible avec des habiletés temporelles dégradées dues à l'absence d'audition. Objectif : La présente étude s'intéresse au bénéfice d'un matériel dynamique basé sur des animations 3D par rapport à un matériel statique dans une tâche de prise de décision. Méthode : 21 can…
Animer le matériel d'apprentissage du code de la route, une solution pour les personnes sourdes et malentendantes.
2016
Séminaire ARPEGE, PARIS, FRANCE, 05-/12/2016 - 05/12/2016; L'examen du code de la route est actuellement sources de difficultés pour la population sourde. Les supports statiques mériteraient d'être animé pour transmettre les rapport temps-vitesse distance, notions fondamentales pour transmettre les notions de sécurité routière. Les résultats de plusieurs travaux sont présentés et discutés.
Demonstration Tasks for Assessment
2017
International audience; Learning from animations is conventionally measured using static assessment tools such as multiple choice tests or extended answer questions. These tools tend to rely heavily on textual information both for presenting the assessment items and as the medium for learner response. However, such assessments are not well aligned with the defining dynamic, pictorial characteristics of animated learning materials. This chapter considers the potential of demonstration tasks to offer more appropriate assessments of learning from animation. In these tasks, learners interact with a manipulable model of the animation’s subject matter to provide an explanatory account of how it c…
La construction territoriale d'une offre périscolaire dans le département de la Côte d'Or : les familles, les collectivités et la réforme
2017
Cette enquête porte sur la mise en ouvre de la réforme de l'articulation des temps scolaires et périscolaires, dans le cadre de la loi d'orientation et de programmation pour la refondation de l’école de la République du 8 juillet 2013, en Côte d'Or. L'enquête dont les résultats sont présentés ici repose sur un matériel substantiel récolté entre 2015 et 2017 formé par une base de données formée à partir de projets éducatifs territoriaux fournis par les communes volontaires. L'objectif de l'enquête était de faire un répertoire de l'offre périscolaire en Bourgogne et de la manière dont les territoires peuvent ou non constituer des ressources dans la mise en ouvre de la réforme, tout en prenant…
Social Animation in Complex Environments
2007
This work presents a market-based social model to produce good quality behavioral animations for groups of intelligent virtual agents. The social model coordinates the activities of groups of virtual characters and also includes social actions in the agent decision-making. We follow the Multi-Agent Resource Allocation approach presented in [2], where agents express their preferences using utility functions. The dynamics of social interactions is inspired by the theory of Piaget [3] over which we have implemented reciprocal task exchanges.
