Negative and positive feedback from a supernova remnant with SHREC
2022
Supernova remnants (SNRs) contribute to regulate the star formation efficiency and evolution of galaxies. As they expand into the interstellar medium (ISM), they transfer vast amounts of energy and momentum that displace, compress and heat the surrounding material. Despite the extensive work in galaxy evolution models, it remains to be observationally validated to what extent the molecular ISM is affected by the interaction with SNRs. We use the first results of the ESO-ARO Public Spectroscopic Survey SHREC, to investigate the shock interaction between the SNR IC443 and the nearby molecular clump G. We use high sensitivity SiO(2-1) and H$^{13}$CO$^+$(1-0) maps obtained by SHREC together wit…
Modeling the mixed-morphology supernova remnant IC 443. Origin of its complex morphology and X-ray emission
2020
The morphology and the distribution of material observed in SNRs reflect the interaction of the SN blast wave with the ambient environment, the physical processes associated with the SN explosion and the internal structure of the progenitor star. IC 443 is a MM SNR located in a quite complex environment: it interacts with a molecular cloud in the NW and SE areas and with an atomic cloud in the NE. In this work we aim at investigating the origin of the complex morphology and multi-thermal X-ray emission observed in SNR IC 443, through the study of the effect of the inhomogeneous ambient medium in shaping its observed structure, and the exploration of the main parameters characterizing the re…
Novel Indexing Method of Relations Between Salient Objects
2011
Since the last decade, images have been integrated into several application domains such as GIS, medicine, etc. This integration necessitates new managing methods particularly in image retrieval. Queries should be formulated using different types of features such as low-level features of images (histograms, color distribution, etc.), spatial and temporal relations between salient objects, semantic features, etc. In this chapter, we propose a novel method for identifying and indexing several types of relations between salient objects. Spatial relations are used here to show how our method can provide high expressive power to relations in comparison to the traditional methods.
La motivación de las tareas digitales mediante “pseudo-ApS” en Biología Celular del grado de Medicina
2020
[ES] Los grupos tutorizados de la asignatura “Biología” de 1º de Medicina (Universitat de València) son un entorno estupendo en el que desarrollas actividades que aúnen el carácter formativo conceptual con el desarrollo competencial transversal. Para ello, en el curso 19-20, hemos implementado la vinculación de la cuenta institucional UV con Microsoft 365, gracias al convenio existente entre ambas entidades para facilitar la utilización de las Tecnologías de la Información y la Comunicación (TICs) en la gestión del tiempo y del intercambio de información. Se propone a los alumnos la elaboración de objetos de aprendizaje propios y originales, en formato animación, que serán utilizados durant…

L'acceptation des dispositifs technologiquesd'auto-production par le consommateur : une approche par l'empowerment psychologique
2022
During the Covid-19 pandemic, the deployment of self-service technologies (self-checking, interactive terminals, smart devices…), allowing to substitute existing service employees and give more autonomy to consumers, have accelerated. In the french academic literature, Cova et al. (2013) conceptualized these devices as « directed self-production » technologies, underlining a more or less imposed transfer of tasks operated by firms. Among consumers, these technological devices have been subjected to ambivalent representations from consumers : some positive representations mainly related to greater autonomy for individuals exist alongside concerns about human contact degradation, macrostructu…

Handling knowledge: Using classroom materials to construct and interpret information requests
2015
Abstract This article contributes to the recent conversation analytic interest in exploring the mechanisms of action formation and ascription by investigating how embodied interactional practices involving material objects relate to the organization of social action. Using as data information request sequences in student–student interaction, the study highlights the material nature of an interactional context and examines how students orient in talk and by bodily-visual means to their and their co-conversants’ textual documents during individual task work. Sequential analyses illustrate how the manual handling of such everyday learning materials as handouts and tasks sheets is not only an i…
The environment of a bilingual classroom as an interactional resource
2018
Both schoolscape studies and recent conversation analytic (CA) research on classroom interaction have demonstrated that material artefacts such as images, texts and different kinds of objects found in classrooms have a significant role in educational practice. This article turns the spotlight on social action within a bilingual classroom, exploring how participants visibly orient to the surrounding material environment during instructional interaction. The data consist of video-recorded lessons from secondary-level education. A multimodal conversation analytic investigation focuses on interactions during which participants attend to classroom texts and semiotic objects in ways that foregrou…
