À la recherche de l’intelligence : de la mesure et de l’organisation

2016

Cet ouvrage aborde le champ des difficultés et des troubles de la vie intellectuelle et cognitive dans l’enfance et, plus généralement, celui des apprentissages et des moyens psychiques d’accès à la connaissance impliqués dans la réussite scolaire en particulier, et dans la réussite plus globale de l’enfant dans sa vie d’enfant, son bien-être, son développement harmonieux et dans sa future vie d’adulte.Fondé sur l’expérience clinique des auteurs auprès des enfants et des adolescents, mais aussi sur un enseignement dans le cadre d’un Diplôme universitaire, ce livre apporte également un éclairage plus large sur les processus impliqués dans les activités d’apprendre, de connaître et de penser,…

2017

Biological invasions are recognized as a significant evolutionary factor over short time scales. In particular, their effect is well recorded on the genetic structure of populations, the patterns of phenotypic evolution and the richness of parasite fauna associated to invasive populations. This study aims at quantifying the consequences of a biological invasion according to these three levels (genetical, phenotypical and parasitological) taking as example the Mozambique tilapia Oreochromis mossambicus. This African cichlid is characterized by an unusual conservation status since it is both (i) ranked among the world's worst invasive species due to its global dispersion during the 20th centu…

TimeSens - un logiciel Web pour l'acquisition et le traitement des données sensorielles

2010

TimeSens est un nouveau logiciel dédié à l'acquisition et au traitement des données d'analyse sensorielle. TimeSens bénéficie de l'expérience et de l'expertise de ChemoSens, la plate-forme d'analyse sensorielle du CSGA. TimeSenspropose la plupart des protocoles standards de l'analyse sensorielle (profil, tests hédoniques, DTS), ainsi que des protocoles originaux (MATI, PSP). Les résultats collectés peuvent être analysés à l'aide de méthodes statistiques traditionnelles ou innovantes.

Single-cell analysis of population context advances RNAi screening at multiple levels

2012

Isogenic cells in culture show strong variability, which arises from dynamic adaptations to the microenvironment of individual cells. Here we study the influence of the cell population context, which determines a single cell's microenvironment, in image‐based RNAi screens. We developed a comprehensive computational approach that employs Bayesian and multivariate methods at the single‐cell level. We applied these methods to 45 RNA interference screens of various sizes, including 7 druggable genome and 2 genome‐wide screens, analysing 17 different mammalian virus infections and four related cell physiological processes. Analysing cell‐based screens at this depth reveals widespread RNAi‐induce…

Exploration de la biodiversité végétale et microbienne pour la qualité et la sureté des aliments

2016

International audience; La qualité et sureté des aliments jouent un rôle important au Vietnam et dans la région de l'Asie du Sud Est. Dans son programme intégral, l'ASEAN met la sureté des aliments parmi des 12 priorités. Plusieurs travaux ont été focalises sur l'exploration de la biodiversité et des innovations technologiques en Asie du Sud Est afin d'améliorer la qualité et de gérer la sureté des aliments. C'est pour ces raisons, nous avons crée un réseau régional avec les soutiens des partenaires francophones et non-francophones en se basant sur les besoins de la région, l'expertise des partenaires et les coopérations étroites. Ce réseau est composé des 10 partenaires dynamiques et actif…

Environmental effects on the covariation among pace-of-life traits

2019

Pace‐of‐life syndromes (POLSs) are suites of life‐history, physiological and behavioural traits that arise due to trade‐offs between allocation to current and future reproduction. Traits generally show covariation that can arise from genetic and environmental influences on phenotypes and constrain the independent evolution of traits, resulting in fitness consequences and impacts on population dynamics. The notion that correlations among traits may vary among populations along environmental gradients suggests an important role for the environment in shaping and maintaining POLSs. However, no synthesis has been attempted of the myriad ways in which environmental factors should influence POLSs…

Evolutionary advantage conferred by an eukaryote-to-eukaryote gene transfer event in wine yeasts

2015

Although an increasing number of horizontal gene transfers have been reported in eukaryotes, experimental evidence for their adaptive value is lacking. Here, we report the recent transfer of a 158-kb genomic region between Torulaspora microellipsoides and Saccharomyces cerevisiae wine yeasts or closely related strains. This genomic region has undergone several rearrangements in S. cerevisiae strains, including gene loss and gene conversion between two tandemly duplicated FOT genes encoding oligopeptide transporters. We show that FOT genes confer a strong competitive advantage during grape must fermentation by increasing the number and diversity of oligopeptides that yeast can utilize as a s…
