Entre 2007 et 2012, des innovations pédagogiques initialement conçues de façon intuitive et ponctuelle par quelques enseignants se sont développées, améliorées et généralisées. Comment ont-elles progressivement pris corps d'un point de vue théorique ? Comment sont-elles devenues les composantes essentielles d'un portfolio qui se développera peut-être bientôt sur plusieurs années du cursus ? Comment l'ensemble s'articule-t-il autour d'un projet de référentiel de compétences facultaire ? [less ▲]

This article presents a study of the use of the Dutch cardinal posture verbs staan (‘stand’), liggen (‘lie) and zitten (‘sit’) by French-speaking learners of Dutch; the data is drawn from a corpus of semi-spontaneous oral picture descriptions. Due to the typological differences between French and Dutch in the spatial domain (see Talmy 2000; Lemmens & Slobin 2008), the use of posture verbs is a highly problematic subject for French-speaking learners of Dutch. As a result, their interlanguage is typically characterized by an overall underuse of posture verbs as well as a confusion of the different posture verbs. Our study evaluates how the use of the posture verbs by the learners aligns with their level of proficiency. Strikingly, the statistical tendencies in our data show that a higher proficiency does not correspond to a more accurate use of posture verbs. At first sight, this seems to suggest that advanced learners have become worse at the use of posture verbs. A more refined analysis, however, shows that despite the increase of errors, the learners adopt more native-like strategies as their level of foreign language proficiency increases, suggesting that they gradually become more aware of the strong locative character of Dutch.

Black rats are major invasive vertebrate pests with severe ecological, economic and health impacts. Remarkably, their evolutionary history has received little attention and there is no firm agreement on how many species should be recognized within the black rat complex. This species complex is native to India and Southeast Asia. According to current taxonomic classification, there are three taxa living in sympatry in several parts of Thailand, Cambodia and Lao People's Democratic Republic, where this study was conducted: two accepted species (Rattus tanezumi, Rattus sakeratensis) and an additional mitochondrial lineage of unclear taxonomic status referred to here as ‘Rattus R3’. We used extensive sampling, morphological data and diverse genetic markers differing in rates of evolution and parental inheritance (two mitochondrial DNA genes, one nuclear gene and eight microsatellite loci) to assess the reproductive isolation of these three taxa. Two close Asian relatives, Rattus argentiventer and Rattus exulans, were also included in the genetic analyses. Genetic analyses revealed discordance between the mitochondrial and nuclear data. Mitochondrial phylogeny studies identified three reciprocally monophyletic clades in the black rat complex. However, studies of the phylogeny of the nuclear exon IRBP and clustering and assignation analyses with eight microsatellites failed to separate R. tanezumi and R3. Morphometric analyses were consistent with nuclear data. The incongruence between mitochondrial and nuclear (and morphological) data rendered R. tanezumi/R3 paraphyletic for mitochondrial lineages with respect to R. sakeratensis. Various evolutionary processes, such as shared ancestral polymorphism and incomplete lineage sorting or hybridization with massive mitochondrial introgression between species, may account for this unusual genetic pattern in mammals.

Dans la nuit du 3 au 4 août 1312, la Cité de Liège est mise à feu et à sang. Sept siècles plus tard, la mémoire collective liégeoise compte encore cet évènement au nombre des jalons les plus tragiques de l’histoire de la Principauté. Les conditions dans lesquelles moururent les patriciens demeurent inqualifiables, de même que les moyens auxquels recourut la masse populaire révoltée pour venir à bout de son adversaire. Cet évènement anecdotique au regard de la grande histoire met en lumière la place ambivalente du feu dans la vie et la mentalité des hommes et des femmes du Moyen Âge. Il invite à une profonde réflexion mêlant des considérations juridiques, spirituelles, symboliques et anthropologiques [less ▲]

Context. Debris discs are a consequence of the planet formation process and constitute the fingerprints of planetesimal systems. Their solar system's counterparts are the asteroid and Edgeworth-Kuiper belts. Aims. The DUNES survey aims at detecting extra-solar analogues to the Edgeworth-Kuiper belt around solar-type stars, putting in this way the solar system into context. The survey allows us to address some questions related to the prevalence and properties of planetesimal systems. Methods. We used Herschel/PACS to observe a sample of nearby FGK stars. Data at 100 and 160 μm were obtained, complemented in some cases with observations at 70 μm, and at 250, 350 and 500 μm using SPIRE. The observing strategy was to integrate as deep as possible at 100 μm to detect the stellar photosphere. Results. Debris discs have been detected at a fractional luminosity level down to several times that of the Edgeworth-Kuiper belt. The incidence rate of discs around the DUNES stars is increased from a rate of ∼ 12.1% ± 5% before Herschel to ∼ 20.2% ± 2%. A significant fraction (∼ 52%) of the discs are resolved, which represents an enormous step ahead from the previously known resolved discs. Some stars are associated with faint far-IR excesses attributed to a new class of cold discs. Although it cannot be excluded that these excesses are produced by coincidental alignment of background galaxies, statistical arguments suggest that at least some of them are true debris discs. Some discs display peculiar SEDs with spectral indexes in the 70–160 μm range steeper than the Rayleigh-Jeans one. An analysis of the debris disc parameters suggests that a decrease might exist of the mean black body radius from the F-type to the K-type stars. In addition, a weak trend is suggested for a correlation of disc sizes and an anticorrelation of disc temperatures with the stellar age. [less ▲]

This text focuses on how teachers and other institutional actors (such as headmasters, psychologists and social workers) offer guidance to pupils in secondary schools. It stresses the epistemological and empirical challenges inherent in a study of decisionmaking in school guidance as used by teachers, based on field theory. The text begins with a presentation of several sociological studies of how teachers construct their judgments about pupils. It emphasizes the strength of the concept of field as a key to understanding the role played by teachers in the formal process of educational (school) guidance, specifically in the case of the French "Grandes Ecoles". This section goes on to show that, with the weakening of the autonomy of (the) educational institutions, (the) French sociology of education moved away from (the) Bourdieu’s perspective, (and) to focus(ed) on the moral pluralism inherent in education and the ethical tensions that institutional actors face. The second part of the text discusses the findings of socioanthropological fieldwork undertaken in secondary schools in the French Community of Belgium. This section argues that the dynamics of judgments made by teachers today canbest be understood through their structural linkages with the structure of the field of secondary education. [less ▲]

Third generation stellar models for asteroseismology of hot B subdwarf stars. A test of accuracy with the pulsating eclipsing binary PG 1336–018

Context. Asteroseismic determinations of structural parameters of hot B subdwarfs (sdB) have been carried out for more than a decade now. These analyses rely on stellar models whose reliability for the required task needs to be evaluated critically. Aims. We present new models of the so-called third generation (3G) dedicated to the asteroseismology of sdB stars, in particular to long-period pulsators observed from space. These parameterized models are complete static structures suitable for analyzing both p- and g-mode pulsators, contrary to the former second generation (2G) models that were limited to p-modes. While the reliability of the 2G models has been successfully verified in the past, this important test still has to be conducted on the 3G structures. Methods. The close eclipsing binary PG 1336−018 provides a unique opportunity to test the reliability of hot B subdwarf models. We compare the structural parameters of the sdB component in PG 1336−018 obtained from asteroseismology based on the 3G models, with those derived independently from the modeling of the reflection/irradiation effect and the eclipses observed in the light curve. Results. The stellar parameters inferred from asteroseismology using the 3G models are found to be remarkably consistent with both the preferred orbital solution obtained from the binary light curve modeling and the updated spectroscopic estimates for the surface gravity of the star. The seismology gives M∗ = 0.471 ± 0.006 M⊙ , R∗ = 0.1474 ± 0.0009 R⊙ , and log g = 5.775 ± 0.007, while orbitology leads to M∗ = 0.466 ± 0.006 M⊙ , R∗ = 0.15 ± 0.01 R⊙ , log g = 5.77 ± 0.06, and spectroscopy yields log g = 5.771 ± 0.015. In comparison seismology from a former analysis based on the 2G models gave very similar results with M∗ = 0.459 ± 0.005 M⊙ , R∗ = 0.151±0.001 R⊙, and log g = 5.739±0.002. We also show that the uncertainties on the input physics included in stellar models have no noticeable impact, at the current level of accuracy, on the structural parameters derived by asteroseismology. Conclusions. The stellar models (both of second and third generation) presently used to carry out quantitative seismic analyses of sdB stars are reliable for the task. The stellar parameters inferred by this technique, at least for those that could be tested (M∗, R, and log g), appear to be both very precise and accurate, as no significant systematic effect has been found.
