Tandem présentiel-distance : articulation difficile, enjeux et perspectives de mutations de l’enseignement et de l’apprentissage au Cap-Vert

This research is in the field of information technology and communication for teaching (ITC) and aims at studying the joint-face and distance in the Cape Verdean context. It is in order to understand this form of blended learning that a device allowing students to share and collaborate around collaborative tasks has been established.The theoretical framework refers to social constructivism, communication mediated by computer (CMC) and written as basic foundation for this search. It has a comprehensive and praxeological reference, the overall objective is to provide insights for easier understanding of the ITC to effectively integrate the use of technological tools in training in teaching French. The approach we have adopted is based on an ethnomethodological approach. The data obtained were analyzed quantitatively and qualitatively, then they were crossed according to the principle of triangulation (Van Der Maren, 1997).This research provides some answers. The use of technological tools facilitates exchanges between students, allowing them to co- construct their learning, and enables feedback on linguistic forms. It also facilitates management and support to students. Technological and technical conditions are also important.Cette recherche s’inscrit dans le domaine des technologies de l’information et de la communication pour l’enseignement (Tice) et a pour objet d’étudier l’articulation du présentiel et de la distance dans le contexte capverdien. Elle vise la compréhension de cette modalité d’apprentissage hybride. Un dispositif permettant aux étudiants d’échanger et de collaborer autour de tâches collaboratives a été mis en place.Le cadre théorique fait référence au socioconstructivisme, à la communication médiée par ordinateur (CMO) et à l’écrit comme fondement de base pour cette recherche. Celle-ci a une visée compréhensive et praxéologique, l’objectif général et à terme étant d’apporter des éclairages permettant d’appréhender plus facilement les Tice en vue de les intégrer efficacement dans des formations en français autorisant l’usage des outils technologiques. La démarche que nous avons adoptée est axée sur une approche ethnométhodologique. Les données obtenues ont été analysées quantitativement et qualitativement puis, elles ont été croisées selon le principe de la triangulation (Van Der Maren, 1997).Cette recherche propose quelques éléments de réponse. L’usage des outils technologiques facilite les échanges entre les étudiants, leur permet de co-construire leur apprentissage, autorise des rétroactions sur les formes linguistiques. Elle facilite l’encadrement et l’accompagnement des étudiants. Les conditions technologiques et techniques sont également importantes

High-resolution CT phenotypes in pulmonary sarcoidosis: a multinational Delphi consensus study

One view of sarcoidosis is that the term covers many different diseases. However, no classification framework exists for the future exploration of pathogenetic pathways, genetic or trigger predilections, patterns of lung function impairment, or treatment separations, or for the development of diagnostic algorithms or relevant outcome measures. We aimed to establish agreement on high-resolution CT (HRCT) phenotypic separations in sarcoidosis to anchor future CT research through a multinational two-round Delphi consensus process. Delphi participants included members of the Fleischner Society and the World Association of Sarcoidosis and other Granulomatous Disorders, as well as members' nominees. 146 individuals (98 chest physicians, 48 thoracic radiologists) from 28 countries took part, 144 of whom completed both Delphi rounds. After rating of 35 Delphi statements on a five-point Likert scale, consensus was achieved for 22 (63%) statements. There was 97% agreement on the existence of distinct HRCT phenotypes, with seven HRCT phenotypes that were categorised by participants as non-fibrotic or likely to be fibrotic. The international consensus reached in this Delphi exercise justifies the formulation of a CT classification as a basis for the possible definition of separate diseases. Further refinement of phenotypes with rapidly achievable CT studies is now needed to underpin the development of a formal classification of sarcoidosis

Cold atoms in space: community workshop summary and proposed road-map

We summarise the discussions at a virtual Community Workshop on Cold Atoms in Space concerning the status of cold atom technologies, the prospective scientific and societal opportunities offered by their deployment in space, and the developments needed before cold atoms could be operated in space. The cold atom technologies discussed include atomic clocks, quantum gravimeters and accelerometers, and atom interferometers. Prospective applications include metrology, geodesy and measurement of terrestrial mass change due to, e.g., climate change, and fundamental science experiments such as tests of the equivalence principle, searches for dark matter, measurements of gravitational waves and tests of quantum mechanics. We review the current status of cold atom technologies and outline the requirements for their space qualification, including the development paths and the corresponding technical milestones, and identifying possible pathfinder missions to pave the way for missions to exploit the full potential of cold atoms in space. Finally, we present a first draft of a possible road-map for achieving these goals, that we propose for discussion by the interested cold atom, Earth Observation, fundamental physics and other prospective scientific user communities, together with the European Space Agency (ESA) and national space and research funding agencies.publishedVersio
