Les compétences sociales : enjeux conceptuels, méthodologiques et pratiques
2015
Ce document comprend quatre chapitres. Le premier est consacré à une réflexion théorique et épistémologique sur la notion de compétences sociales et les enjeux qu'elle soulève. Dans un deuxième chapitre, nous nous centrerons sur la mesure de cette notion dans le domaine scolaire et professionnel à partir d'une recension et une analyse des différents outils existants. Une analyse de programmes visant à améliorer l'insertion professionnelle des jeunes par l'intermédiaire du développement des compétences sociales sera réalisée dans un troisième chapitre. Enfin, le quatrième chapitre aura une visée plus applicative puisque nous proposerons des pistes de réflexions et d'actions pour développer l…
Further Evidence that Papillomavirus Capsids Exist inTwo DistinctConformations
2003
ABSTRACT Cell surface heparan sulfate proteoglycans (HSPGs) serve as primary attachment receptors for human papillomaviruses (HPVs). To demonstrate that a biologically functional HPV-receptor interaction is restricted to a specific subset of HSPGs, we first explored the role of HSPG glucosaminoglycan side chain modifications. We demonstrate that HSPG O sulfation is essential for HPV binding and infection, whereas de-N-sulfated heparin interfered with VLP binding but not with HPV pseudoinfection. This points to differences in VLP-HSPG and pseudovirion-HSPG interactions. Interestingly, internalization kinetics of VLPs and pseudovirions, as measured by fluorescence-activated cell sorting analy…
Conservation genetics of endangered leaf-beetle Cheilotoma musciformis populations in Poland
2012
Steppe-like habitats in Europe are seriously threatened as a result of fragmentation and anthropogenic degradation, at least in western and central parts. Considering the dramatic loss of steppe-like habitats, the evaluation of genetic variation in populations of steppe species is of immediate importance if appropriate conservation measures are to be undertaken. In this paper, we examine the genetic diversity of the highly endangered populations of the leaf-beetle Cheilotoma musciformis, which inhabits only a limited area in south-central Poland, which is geographically isolated from the continuous range of this species. Both mitochondrial and nuclear markers show that the Polish population…
Geographic Distribution and Niche Divergence of Two Stinkbugs,Parastrachia japonensisandParastrachia nagaensis
2014
Parastrachiidae is a small stinkbug family containing only one genus and two species, Parastrachia japonensis (Scott) (Hemiptera: Heteroptera: Pentatomoidea) and Parastrachia nagaensis Distant. The geographic distribution of the genus has been poorly studied. Niche conservatism refers to that idea that closely related species are more ecologically similar than would be expected, whereas niche divergence predicts they occupy distinct niche spaces. The existence of only two species within one genus suggests niche conservatism or differentiation might exist among them. Herein, the distribution of the genus was mapped, potential distributions were predicted using ecological niche modeling, and …
Inflorescence-visiting insects of a functionally dioecious wild grapevine
2018
The wild grapevine [Vitis vinifera L. subsp. sylvestris (Gmelin) Hegi] is the Eurasian dioecious ancestral form of mostly monoecious domesticated cultivars (Vitis vinifera subsp. vinifera). There are different hypotheses about grapevine pollination, varying from insect to wind pollination to spontaneous self-pollination. The aim of this paper is to update our knowledge on the biology of the wild grapevine by studying the insects visiting their inflorescences. During the fieldworks, floral visitors were observed, captured and identified. The most frequent insects visiting both sexes of wild grapevine were beetles (55%) followed by bees (45%). The present study shows that although in vineyard…
Il suolo come risorsa
2011
La Ley del Suelo del 2007 ha segnato una svolta radicale nelle politiche urbane e territoriali spagnole. L'articolo cerca di comprendere "cosa" e "come" cambia l'urbanistica in Spagna alla luce delle recenti riforme legislative.
Inducible Genetic Code Expansion in Eukaryotes
2020
Abstract Genetic code expansion (GCE) is a versatile tool to site‐specifically incorporate a noncanonical amino acid (ncAA) into a protein, for example, to perform fluorescent labeling inside living cells. To this end, an orthogonal aminoacyl‐tRNA‐synthetase/tRNA (RS/tRNA) pair is used to insert the ncAA in response to an amber stop codon in the protein of interest. One of the drawbacks of this system is that, in order to achieve maximum efficiency, high levels of the orthogonal tRNA are required, and this could interfere with host cell functionality. To minimize the adverse effects on the host, we have developed an inducible GCE system that enables us to switch on tRNA or RS expression whe…
Sociologie de l'école : 6ème édition
2022
Cette 6eédition, totalement réactualisée, d’un manuel devenu « la » référence sur le monde de l’école, des élèves et des enseignants, explore le domaine de manière systématique et objective, et sous des aspects divers : place de l’école dans la société (politiques scolaires, inégalités de carrière, enjeux de la réussite scolaire, évolution des analyses théoriques), mais aussi acteurs et pratiques (profession enseignante, programmes, pratiques éducatives des familles, métiers d’élève).L’ouvrage propose ainsi de nombreux éléments sur les effets des politiques éducatives, la construction et les effets de ségrégation scolaire, ou encore les changements introduits par le renouvellement des ensei…
Un sistema formativo ancora da costruire. Riflessioni e proposte per la formazione iniziale degli educatori per la prima infanzia
2022
Mettendo in relazione la formazione iniziale di educatori/educatrici e insegnanti per la prima infanzia con le conoscenze relative allo sviluppo, alle modalità di apprendimento e ai bisogni dei bambini nei primi sei anni di vita, il mio intervento si centra sulla ipotesi di un curriculo formativo unitario. Individua quindi sia le aree disciplinari fondamentali e i possibili contenuti, sia i modelli formativi più efficaci per delineare un profilo professionale specifico, conducendo un approfondimento sull’apprendimento dall’esperienza all’interno dell’Università e sulle modalità di tirocinio maggiormente efficaci. In base alla normativa vigente, delineo poi le criticità del modello formativo…
Simúlidos (Diptera: Simuliidae) de los ríos de la Comunidad Valenciana: Implicaciones en la salud pública y su control
2018
Los simúlidos (Diptera: Simuliidae) se encuentran distribuidos por casi todo el mundo. Su presencia está ampliamente influenciada por la disponibilidad de cursos de agua con flujo, necesarios para el desarrollo de los estados inmaduros (ADLER & McCREADIE, 2002), ocupando ambientes que van desde cursos temporales hasta grandes ríos. Los simúlidos crían en aguas corrientes, se les puede encontrar tanto en arroyos y torrentes de montaña como en los lentos flujos de agua de los ríos en sus tramos bajos. Además, existen unas pocas especies las cuales se han adaptado a flujos de agua tan escasos donde incluso la corriente es casi imperceptible (BURGER, 1987). En cualquier caso, se sabe que cierto…
