Encuentro de saberes: Huellas de memoria pluriversa y descolonización de la Universidad contemporánea
2018
This paper studies the Encounter of Knowledge as a project that, by welcoming mestres and mestras of ancestral knowledge into universities, contributes to decolonize higher education, broadening its field of memory. Based on a systematization exercise, we established a theoretical dialogue with Bajtin and Bejamin. Based on the participation of four mestres -Lucely Pío, raicera del Cerrado, Mãe Lu and Tata Mutá Imé, religious leaders of Candomblé and the political leader and shaman Álvaro Tukano of the Tukano nation- we show how the project promotes in the contemporary Brazilian university a space of mnemic pluriversity, capable of activating diverse narrative planes (biographical, political…
Global Estimation of Biophysical Variables from Google Earth Engine Platform
2018
This paper proposes a processing chain for the derivation of global Leaf Area Index (LAI), Fraction of Absorbed Photosynthetically Active Radiation (FAPAR), Fraction Vegetation Cover (FVC), and Canopy water content (CWC) maps from 15-years of MODIS data exploiting the capabilities of the Google Earth Engine (GEE) cloud platform. The retrieval chain is based on a hybrid method inverting the PROSAIL radiative transfer model (RTM) with Random forests (RF) regression. A major feature of this work is the implementation of a retrieval chain exploiting the GEE capabilities using global and climate data records (CDR) of both MODIS surface reflectance and LAI/FAPAR datasets allowing the global estim…
Biological and Mechanical Characterization of the Random Positioning Machine (RPM) for Microgravity Simulations
2021
The rapid improvement of space technologies is leading to the continuous increase of space missions that will soon bring humans back to the Moon and, in the coming future, toward longer interplanetary missions such as the one to Mars. The idea of living in space is charming and fascinating; however, the space environment is a harsh place to host human life and exposes the crew to many physical challenges. The absence of gravity experienced in space affects many aspects of human biology and can be reproduced in vitro with the help of microgravity simulators. Simulated microgravity (s-μg) is applied in many fields of research, ranging from cell biology to physics, including cancer biology. In…
Current Social and Rangeland Access Trends among Pastoralists in the Western Algerian Steppe
2021
International audience; In the western Algerian steppe, the public authorities have carried out actions aimed at rural development (agricultural development programs) and combating desertification (grazing reserves) to counter the significant and rapid loss of vegetation cover of pastures by overgrazing, and the consequent impacts on local livelihoods. In the Rogassa area, these actions have impacted land tenure and the ancestral and collective way of land use and access. These changes have caused transformations in lifestyle and pasture management. This research aims to characterize how such changes are affecting local pastoralists and what their perceptions are about them. A selective sam…
Més enllà de Kohlberg: l'aprenentatge ètic per a la coherència entre judici, sentiments i accions morals
2017
espanolPara la comunidad educativa el desarrollo moral sigue siendo un asunto de preocupacion. Varios agentes educativos dedican tiempo y esfuerzo a un tema que, actualmente, evidencia una clara separacion entre lo teorico y lo practico, un sesgo entre lo que uno piensa y lo que uno hace, entre el razonamiento y las acciones morales. Las finalidades y las intenciones de los agentes educativos son respetables; pero contrariamente a estas, ninos y adolescentes actuan de manera demasiado reactiva y les cuesta generalizar ciertos comportamientos. En esta linea, el planteamiento de Kohlberg, centrado en el desarrollo del juicio y el razonamiento moral, parece proporcionarles principalmente eleme…
TISSBERT: A benchmark for the validation and comparison of NDVI time series reconstruction methods
2018
[EN] This paper introduces the Time Series Simulation for Benchmarking of Reconstruction Techniques (TISSBERT) dataset, intended to provide a benchmark for the validation and comparison of time series reconstruction methods. Such methods are routinely used to estimate vegetation characteristics from optical remotely sensed data, where the presence of clouds decreases the usefulness of the data. As for their validation, these methods have been compared with previously published ones, although with different approaches, which sometimes lead to contradictory results. We designed the TISSBERT dataset to be generic so that it could simulate realistic reference and cloud-contaminated time series …

Contribución a un futuro sostenible. Una dimensión necesaria y posible en toda acción e investigación educativa
2005
El estudio de los errores conceptuales, preconcepciones, concepciones alternativas, etc., ha constituido posiblemente la línea de investigación más desarrollada en didáctica de las ciencias. Miles de artículos publicados lo atestiguan (Duit, 2004). Sin embargo, la inmensa mayoría de estos trabajos se centra en conceptos concretos de los distintos campos de la ciencia y, en cambio, apenas si se ha prestado atención a otras concepciones, tanto del alumnado como del profesorado, con notable influencia en el proceso de enseñanza/ aprendizaje, como las referidas a la naturaleza de la ciencia y, más particularmente, a las relaciones CTSA. Para ver en qué medida este reduccionismo persiste hoy en …
S’aimer à l’heure du numérique : la relation conjugale à l’épreuve de l’hyperconnectivité
2014
L’introduction des nouveaux objets connectés (NOC) dans les foyers vient réinterroger la relation conjugale. Avec les objets nomades, le couple doit faire face à un individualisme connecté. Ils amplifient notamment la privatisation des territoires dans l’espace domestique semblant de ce fait affecter la conversation conjugale. À travers notre enquête, nous avons constaté que les technologies de l’information et de la communication (TIC) peuvent certes avoir un impact négatif sur la relation de couple, mais peuvent a contrario venir renforcer la relation en donnant entre autres une nouvelle place à l’écrit dans la communication conjugale. Des différences apparaissent toutefois selon les type…
Rotational effects on the oscillation frequencies of newly born proto-neutron stars
2003
In this paper we study the effects of rotation on the frequencies of the quasi-normal modes of a proto-neutron star (PNS) born in a gravitational collapse during the first minute of life. Our analysis starts a few tenths of seconds after the PNS formation, when the stellar evolution can be described by a sequence of equilibrium configurations. We use the evolutionary models developed by Pons et al. (1999; 2001) that describe how a non rotating star cools down and contracts while neutrino diffusion and thermalization processes dominate the stellar dynamics. For assigned values of the evolution time, we set the star into slow rotation and integrate the equations of stellar perturbations in th…
