Numerous students are having school difficulties linked to the way they learn. Some authors speak of a “metacognitive deficit”. We refer to a “sleeping potential” instead (Frenkel, 2013, in press; Frenkel & Deforge, in press; Frenkel & Nobile, 2013). Be it psychologists, teachers or parents, all wish to develop their skills in order to help these students. This is the case in primary and secondary school. Metacognitive abilities play a central role in learning (e.g., Frenkel & Deforge, in press; Giasson, 2001; Grangeat, 1997; Hessels & Hessels-Schlatter, 2010b; Lumbelli, 2003; Poissant, Poëllhuber & Falardeau, 1994; Rozencwajg, 2003; Veenman, Kok & Blöte, 2005) and thus in successful school learning (Büchel, 2013a, 2013b; Van der Stel & Veenman, 2010; Wang, Haertel & Walberg, 1994). However, studying them requires that we clarify what is meant by “metacognition” and “metacognitive abilities”. In this framework, we developed the EDUCA + project which is intended to provide possible solutions. EDUCA + is based on wide field experience. Its theoretical background is based on a substantial review of the literature. Its objective is to increase the expertise of “front line” field workers by developing specific products such as tools, training courses, services, and a website (Frenkel, in press). This will notably enable them to develop their expertise, detect « sleeping » potential, diagnose, give advice when necessary, intervene (prevention and remediation) and use the tools efficiently. Two types of tools are being designed. On the one hand, assessment tools (tests allowing to put forward the learner’s strengths and weaknesses as well as the scope of his/her “sleeping potential”). On the other hand, intervention tools (short prevention vs. remediation programs). This also includes training courses and services. The creation of a website also aims to reinforce the actions of EDUCA + (personalized access depending on the internaut’s profile: students, parents, professionals). The aim of this paper is to present this research project and its main theoretical background. [less ▲]

Culicoides biting midges (Diptera: Ceratopogonidae) serve as biological vectors for several pathogens, including the Bluetongue virus and the recently described Schmallenberg virus in northern Europe. These diseases have caused considerable direct and indirect economic losses to the sheep and cattle industries. This study undertaken between August and December 2007 on a sheep farm in the Namur province (Belgium) aims to evaluate Culicoides populations present inside a partially opened sheepfold and in a nearby sheep meadow, using light traps. The comparative analysis of insects trapped at 18 dates at regular intervals showed that Culicoides were most abundant Inside this livestock building (17,450 midges) than in surrounding meadow (1,121 midges); this meadow had however a greater species diversity. The two species C. obsoletus and C. scoticus constituting the Obsoletus complex predominated for all trappings and females were much more numerous than males. Important capture of engorged females of the Obsoletus complex inside the sheepfold seems to reflect the possibility of an opportunistic endophagous behavior. Maintaining sheep inside livestock buildings in order to reduce the risk of Culicoides bites – and thus of pathogens transmission – however requires to limit biting midge populations which are likely to enter or to develop inside these buildings. Implementation of effective sanitation and hygiene measures against midges present inside farms, as well as establishing of measures to protect livestock against intrusion and improvement of “midge-proofing” of animal housing are therefore highly recommended.

Cet article étudie le rôle que peut jouer la bibliothèque en temps d’information overload et part des deux composantes de base du phénomène de l’infobésité : en premier lieu, un flot de données objectivement important, et, en second lieu, la manière dont ces données sont traitées par le sujet humain, l’usager. Pour gérer l’afflux de données constant, la bibliothèque offre d’abord un outillage technique. Le développement récent des outils « discovery » peut être resitué dans cette veine. Deuxièmement, c’est en investissant dans les compétences informationnelles des utilisateurs que la bibliothèque peut lutter contre le versant subjectif de l’infobésité. Dans ce processus, la communication joue un rôle primordial. [less ▲]

Le norovirus murin (MuNoV), un virus à ARN de polarité positive appartenant à la famille des Caliciviridae, est considéré comme un modèle adéquat pour les infections humaines à norovirus, une des causes étiologiques les plus importantes dans les cas de gastroentérite épidémique ou sporadique dans le monde entier. Quatre cadres de lecture ouverts (ORF) sont décrits au sein de son génome : l’ORF1 code les protéine non structurales (NS), dont l’ARN polymérase ARN dépendante virale (RdRp) ; l’ORF2 code l’unique protéine de capside (VP1), dans laquelle sont décrites deux régions : une relativement conservée (domaine « shell ») et une autre beaucoup plus variable (domaine « protruding ») ; l’ORF3 code une protéine structurale mineure ; et l’ORF4, actuellement uniquement décrit chez les virus génétiquement apparentés au MuNoV, code un facteur de virulence. Dans cette étude, nous démontrons par séquençage à haut débit que, durant des passages successifs du MuNoV en culture cellulaire, les taux de substitution, estimés par inférences Bayésiennes, n’ont pas significativement différé au travers des cinq régions génomiques ciblées à l’exception d’une région bien précise. Ces taux étaient similaires pour quatre régions englobant des séquences partielles codant les protéines non structurales NS1-2, NS5, NS6 et NS7 (RdRp) et VP1 dans sa région conservée (incluant également l’ORF4). Dans la région codant partiellement la protéine structurale mineure, ce taux de substitution, exprimé en substitution/site/jour, a été cependant estimé être plus élevée d’au moins une unité logarithmique. La localisation précise des mutations ponctuelles détectées (substitution, délétion et insertion) est rapportée ainsi que l’augmentation ou la diminution quantitative du nombre des séquences qui les présentaient au cours de dix passages successifs en culture cellulaire. Les localisations des mutations non silencieuses ont aussi été représentées dans une modélisation tridimensionnelle de quatre des cinq régions étudiées. Ces résultats ont d’importantes implications pour différents champs de recherche sur les norovirus, spécialement en termes de diagnostic, de méthodologie de classification et d’évolution génétique.

Methane (CH4) plays an important role in the Earth’s climate system. The atmospheric CH4 concentration has increased in concert with the industrialization, but since the mid 80’s the CH4 growth rate decreased to reach a near-zero level in 2000 and started to increase again from 2007 on. However, the underlying variations in sources and/or sinks that cause these variations are to date not well understood. To predict future climate, it is essential to unravel the processes controlling the CH4 cycle, especially in the Arctic regions, which are highly vulnerable to climate change and contain large CH4 reservoirs. Recently, an unexpected CH4 excess has been reported above Arctic sea-ice showing that sea-ice might play a significant role in the CH4 cycle. Nonetheless, the nature of the process leading to CH4 production in or nearby sea-ice has not yet been identified. We applied a new multi-proxy approach merging atmospheric chemistry, glaciology and biogeochemistry to understand and quantify the processes responsible for the CH4 excess above sea-ice. We performed CH4 isotope (13C and D) analyses on sea-ice samples, as well as microbial (lipid biomarkers) and geochemical measurements, to determine the possible pathways involved in CH4 production and removal in or nearby sea-ice. We will present results from sea-ice samples drilled above the shallow-shelf in Barrow (Alaska) from January to June 2009 as well as above deep Southern Ocean locations in 2013. Those results allow investigating the seasonality and spatial variability in methane formation and removal pathways associated to the methane enclosed in sea-ice. [less ▲]

According to previous studies, pCO2 fluxes measured over Arctic sea ice are higher than those measured over Antarctic sea ice. We hypothesized that this was due to enhanced respiration in Arctic sea ice, as a consequence of higher riverine inputs of dissolved organic carbon (DOC) into Arctic seawater. We tested this hypothesis during the Interice V experiment at the HSVA (Hamburg) environmental test basin facility. We reproduced the growth and decay cycle of sea ice in replicate mesocosms (1 m3) filled with North Sea water (NSW series), and compared these with another series of mesocosms to which humic-rich river water had been added (10%) to increase the DOC concentration (R series). Primary producers were excluded from the experiment. The evolution of the temperature, salinity, DOC, pCO2 and bacterial biomass and production were measured in ice sampled at regular intervals throughout the experiment, as well as in the under-ice water. In addition, ice-air pCO2 fluxes were continuously monitored over both NSW and R mesocosms. pCO2 values in ice were higher in the R ice than in the NSW ice. This is attributed to the DOC content and bacterial respiration, rather than to the ice physical properties (i.e., ice permeability constrained by the ice temperature and salinity). Indeed, R ice had higher DOC content and bacterial production than the NSW ice while both showed similar physical properties. The evolution of the ice-air pCO2 fluxes was consistent with the evolution of pCO2 in ice. The fluxes were, as expected, positive (from sea ice to the atmosphere) during ice growth and negative (from the atmosphere to the ice) during ice melt. [less ▲]
