Kohti sosioemotionaalisia taitoja ja lasten osallisuutta tukevaa toimintakulttuuria – ProVaka-toimintamallin pilottivaiheen analyysi
2021
Kaikkien lasten osallisuuden tukeminen edellyttää tarvittavan kehityksen ja oppimisen tuen järjestämistä varhaiskasvatukseen. Osallistavan varhaiskasvatuksen toimintakulttuurin kehittämisellä tuetaan koko lapsiryhmän kanssa toteutettavia toimintatapoja tukemaan kaikkien lasten käyttäytymistä ja sosioemotionaalisia taitoja. Käyttäytymispsykologinen Positiivisesti ryhmässä oppiva varhaiskasvatus (ProVaka) -toimintamalli edistää tutkimusnäyttöön pohjautuvien menetelmien käyttöönottoa sosiaalisen käyttäytymisen tukemisessa. ProVaka-toiminnassa korostuvat yhteisesti sovitut ja selkeät käyttäytymisodotukset, toivotun käyttäytymisen systemaattinen opettaminen ja käyttäytymiseen kohdennetulla posit…
Vacunas y evolución: ¿Por qué es importante entender la diversidad genética de los patógenos?
2013
Desde el punto de vista de las intervenciones en salud pública no hay mejor arma que aquella que permite prevenir la transmisión o aparición de la enfermedad. Dentro del campo de las enfermedades infecciosas las vacunas se han convertido en esa arma y han permitido controlar muchas de ellas. Hoy en día hay un gran número de enfermedades infecciosas emergentes para las que no existen vacunas o enfermedades olvidadas que están reemergiendo. Nuevas vacunas se están desarrollando para atacar a los patógenos que están relacionados con ellas. Sin embargo, y a pesar de la importancia del diseño de una buena vacuna, la diversidad genética de los patógenos no se ha tenido siempre en cuenta. El estud…

Maternal weaning practices and their impact on infant's acceptance of new food
2010
Objective. The introduction of solid foods is a major step in the development of food behaviour. Previous studies showed that higher sensory variety in weaning period can later influence infant's acceptance of new food. The aim of the present study is (i) to describe precisely the different maternal weaning practices, (ii) to relate them with the individual mothers' and infants' characteristics, (iii) to study if these practices could impact infant's acceptance of new foods. Methods. Mothers (n=121) were requested to record each food proposed to their infant detailed from a sensory point of view and to score the level of its acceptance at the 4 first presentations. The beginning of the wean…
Heterozygote advantage and pleiotropy contribute to intraspecific color trait variability
2022
The persistence of intrapopulation phenotypic variation typically requires some form of balancing selection because drift and directional selection eventually erode genetic variation. Heterozygote advantage remains a classic explanation for the maintenance of genetic variation in the face of selection. However, examples of heterozygote advantage, other than those associated with disease resistance, are rather uncommon. Across most of its distribution, males of the aposematic moth Arctia plantaginis have two hindwing phenotypes determined by a heritable one locus-two allele polymorphism (genotypes: WW/Wy = white morph, yy = yellow morph). Using genotyped moths, we show that the presence of o…

La Géométrie pour l'Unicité, la Parcimonie et l'Appariement des Estimateurs Pénalisés
2022
During the talk we will give a necessary and sufficient condition for the uniqueness of a penalized least squares estimator whose penalty term is a polyhedral norm. Our results cover many methods including the OSCAR, SLOPE and LASSO estimators as well as the related method of basis pursuit. The geometrical condition for uniqueness involves how the row span of the design matrix intersects the faces of the dual normunit ball. Theoretical results on sparsity by LASSO and basis pursuit estimators are deduced from this condition via the characterization of accessible sign vectors for these two methods.
The role of lipid metabolism in the acquisition of desiccation tolerance inCraterostigma plantagineum: a comparative approach
2013
Summary Dehydration leads to different physiological and biochemical responses in plants. We analysed the lipid composition and the expression of genes involved in lipid biosynthesis in the desiccation-tolerant plant Craterostigma plantagineum. A comparative approach was carried out with Lindernia brevidens (desiccation tolerant) and two desiccation-sensitive species, Lindernia subracemosa and Arabidopsis thaliana. In C. plantagineum the total lipid content remained constant while the lipid composition underwent major changes during desiccation. The most prominent change was the removal of monogalactosyldiacylglycerol (MGDG) from the thylakoids. Analysis of molecular species composition rev…
Drying process strongly affects probiotics viability and functionalities
2015
International audience; Probiotic formulations are widely used and are proposed to have a variety of beneficial effects, depending on the probiotic strains present in the product. The impact of drying processes on the viability of probiotics is well documented. However, the impact of these processes on probiotics functionality remains unclear. In this work, we investigated variations in seven different bacterial markers after various desiccation processes. Markers were composed of four different viability evaluation (combining two growth abilities and two cytometric measurements) and in three in vitro functionalities: stimulation of IL-10 and IL-12 production by PBMCs (immunomodulation) and…
Regulation of hdc expression and HDC activity by enological factors in lactic acid bacteria.
2008
Aims: The aim of this work was to study the influence of enological factors on the histidine decarboxylase gene (hdc) expression and on histidine decarboxylase enzyme (HDC) activity in Lactobacillus hilgardii, Pediococcus parvulus and Oenococcus oeni. Methods and Results: Cell extracts and whole cells were used. Glucose, fructose, malic acid and citric acid diminished the hdc expression. Ethanol did not increase hdc expression or activity in cells, but increased HDC activity. Temperature and pH had effect on the activity of HDC but not on hdc expression. Tartaric acid and l-lactic acid, and sulphur dioxide (SO2) had no effect on enzyme synthesis and activity. Bacterial species differ in t…
