Il est exceptionnel de pouvoir appliquer la démarche palethnologique, si fréquemment développée pour le Magdalénien, aux gisement du Paléolithique supérieur ancien dans le Bassin parisien, dans la mesure où ils sont rares, c'est indéniable, mais aussi en raison d'un état de conservation généralement médiocre de la plupart d'entre eux. Le site d'Ormesson, situé en Seine-et-Marne, à proximité de la vallée du Loing et de la ville de Nemours, constitue depuis 2009, année de la première fouille, un gisement-laboratoire pour l'approche palethnographique de différentes populations de la fin du Paléolithique moyen au Badegoulien. A travers cet exemple devenu désormais une référence pour le Paléolithique supérieur ancien, nous nous poserons la question suivante : Palethnologie ou pâle ethnologie ? [less ▲]

This study’s main aim is to identify plant species showing anti-oxidant, anti-inflammatory and skin whitening properties. A selection of 89 samples from previous infield studies on the traditional uses of plants in Mayotte were analyzed. The anti-oxidant activity was assessed using the α, α-diphenyl-β-picrylhydrazyl (DPPH) method developed by Blois [1]. The anti-inflammatory activity and the skin whitening activity were both assessed through the study of inhibition kinetics from specific enzymes: respectively, lipoxygenase (EC 1.13.11.12) due to its important role in the leukotriene pathway and tyrosinase (EC. 1.14.18.1) as it takes part in the melanogenesis pathway. The IC 50 value for each sample and for each activity was obtained using UV/Vis spectrophotometric technics. These IC 50 were then compared with the ones obtained from known molecules found in the literature: namely, (±)-6-Hydroxy-2,5,7,8-tetramethylchromane-2-carboxylic acid (IC50 = 4,388 µM) for the anti-oxidant activity, nordihydroguaiaretic acid (IC50 = 3,5µM) for the anti-inflammatory activity and kojic acid (IC50 = 722 µM) for the anti-tyrosinase activity. The most effective anti-oxidant activity was observed in fresh leaves from Acalypha wilkesiana Müll.Arg. (IC50 = 0,381 g/L) and Leea guineensis G. Don. (IC50 = 0,225 g/L) as well as in dried roots from Litchi chinensis Sonn. (IC50 = 0,346 g/L). All results are expressed in grams of fresh matter. According to the preliminary tests for the-anti-inflammatory and skin whitening activities, the crude extracts from Kalanchoe pinnata Lam. Pers., Litchi chinensis Sonn., Zingiber zerumbet (L.) Sm., Leea guineensis G. Don. and Paullinia pinnata L. are likely to show promising activities. [less ▲]

We present our investigations on two interferometric methods suitable for industrial conditions dedicated to the visualization of vibration modes of aeronautic blades. First, we consider long-wave infrared (LWIR) electronic speckle pattern interferometry (ESPI). The use of long wavelength allows measuring larger amplitudes of vibrations compared with what can be achieved with visible light. Also longer wavelengths allow lower sensitivity to external perturbations. Second, shearography at 532 nm is used as an alternative to LWIR ESPI. Both methods are used in time-averaged mode with the use of phase-stepping. This allows transforming Bessel fringes, typical to time averaging, into phase values that provide higher contrast and improve the visualization of vibration mode shapes. Laboratory experimental results with both techniques allowed comparison of techniques, leading to selection of shearography. Finally a vibration test on electrodynamic shaker is performed in an industrial environment and mode shapes are obtained with good quality by shearography. [less ▲]

Functional biomarkers able to identify multiple sclerosis (MS) patients at high risk of fast disability progression are lacking. The aim of this study was to evaluate the ability of multimodal (upper and lower limbs motor, visual, lower limbs somatosensory) evoked potentials (EP) to monitor disease course and identify patients exposed to unfavourable evolution. One hundred MS patients were assessed with visual, somatosensory and motor EP and rated on the Expanded Disability Status Scale (EDSS) at baseline (T0) and about 6 years later (T1). The Spearman correlation (rS) was used to evaluate the relationship between conventional EP scores and clinical findings. Multiple (logistic) regression analysis estimated the predictive value of baseline electrophysiological data for three clinical outcomes: EDSS, annual EDSS progression, and the risk of EDSS worsening. In contrast to longitudinal correlations, cross-sectional correlations between the different EP scores and EDSS were all significant (0.33 ≤ rS < 0.67, p < 0.001). Baseline global EP score and EDSS were highly significant predictors (p < 0.0001) of EDSS progression 6 years later. The aseline global EP score was found to be an independent predictor of the EDSS annual progression rate (p < 0.001), and of the risk of disability progression over time (p < 0.005). Based on a ROC curve determination, we defined a Global EP Score cut off point (17/30) to identify patients at high risk of disability progression illustrated by a positive predictive value of 70 %. This study provides a proof of the concept that electrophysiology could be added to MRI and used as another complementary prognostic tool in MS patients. [less ▲]

Rwanda. Through us, humanity (2005), a movie by Marie-France Collard, follows on from the play Rwanda 94, a project in which she tool part as a author and videographer. Showcased in 2000, the play arises questions about memory, representation, and commitment. The documentary was carried out during artist collective Groupov's tour in Kigaly on the occasion of the commemoration of the genocide's tenth anniversary. It brings those topics up again, gets back to the reception of the play by the Rwandan audience and, in a broader way, to a country in mourning. [less ▲]

Analogical reasoning development maintains a mutual influence with language acquisition: the use of relational labels helps to resolve analogical reasoning tasks (Christie & Gentner, 2014) while analogical reasoning enables the acquisition of new linguistic concepts or structures (Gentner & Namy, 2006). This link has driven some authors to examine the analogical reasoning ability of children with Specific Language Impairment. Those children have poorer analogical reasoning performance than their age-matched peers without language disorders (Leroy et al., 2012 ; Leroy et al., 2014). So, children with SLI seem to have an analogical reasoning weakness which could be linked to their language disorders. Thus, our goal here is to measure the ability of children with SLI to solve analogies, and to compare it to chronological age-matched but also to linguistic age-matched peers without language disorders. Our hypotheses here are the followings: children with SLI have weaker analogical reasoning competence compared to chronological age-matched peers and similar or weaker analogical reasoning competence compared to language-matched peers. To test these hypotheses, we use a scene analogy task composed of pictures of 20 relations (Richland et al., 2006) varying in relational complexity (binary or ternary relations) and in perceptual distraction. Twenty children with SLI are matched to chronological age and linguistic age peers without language disorders. Children with SLI have poorer performance then their age-matched peers but they have similar performance to their language-matched peers. This data reinforces the idea of a link between analogical reasoning and language, also in children with SLI. However, the nature of this link should still be clarified. [less ▲]

Genau wie bei allen anderen Bestandteilen Belgiens ist auch das Erscheinungsbild der Deutschsprachigen Gemeinschaft durch die sechste Staatsreform grundlegend verändert worden. Sie verfügt fortan über die konstitutive Autonomie – das bedeutet, die Funktionsweise ihrer Regierung und ihres Parlamentes zu regeln. Vor allem hat sich ihr Handlungsspielraum im Bereich der kulturellen und personenbezogenen Angelegenheiten ebenso wie bei der Französischen und Flämischen Gemeinschaft erweitert: Familienleistungen, Gesundheitsversorgung, Personenbeistand, Justizhaus, elektronische Überwachung, Industrielehre, … Zudem hat die Wallonische Region ihr die Ausübung neuer Zuständigkeiten im Bereich des Tourismus, der Beschäftigung und der Gemeinden übertragen. Der vorliegende Courrier hebdomadaire macht eine Bestandsaufnahme der Zuständigkeiten sowie der Finanzierung der Deutschsprachigen Gemeinschaft und identifiziert dabei die Veränderungen, die die sechste Staatsreform in dieser Hinsicht gebracht hat. Er geht auf die politischen Debatten ein, die diese Reformen begleitet haben und auf die Art und Weise, wie diese bereites teilweise umgesetzt worden sind. Er rekapituliert auch wie die Deutschsprachigen Gemeinschaft innerhalb der Europäischen Union, auf föderaler Ebene, innerhalb der Wallonischen Region und in der Provinz Lüttich vertreten wird . Die Studie zeigt die Perspektiven auf, die sich der Deutschsprachigen Gemeinschaft in Zukunft eröffnen. Diese fordert dabei zum einen, die Gesamtheit der regionalen und provinzialen Zuständigkeiten auf ihrem Gebiet ausüben zu können und zum anderen, einen sichtbareren Platz in der institutionellen Architektur des Landes einzunehmen. Da diesen Ansprüchen bislang nicht nachgekommen wurde, möchten die deutschsprachigen politischen Verantwortlichen die Diskussion im Laufe der kommenden Jahre wieder aufgreifen. [less ▲]
