Dans quelle mesure la littérature est-elle enseignée dans les manuels belges et français contemporains en interaction avec d’autres formes artistiques, qu’elles soient plastiques, visuelles, musicales, architecturales, cinématographiques… ? Voici la question qui s’inscrit au cœur de notre propos. En effet, la présente contribution étudie l’articulation entre littérature et art telle qu’elle se donne à voir dans les manuels belges et français actuels destinés aux élèves du secondaire inférieur (collège) et supérieur (lycée). Pour ce faire, nous commencerons par décliner plusieurs questions de recherches plus circonscrites avant de discuter les concepts-clés de notre problématique. L’étude repose sur des fondements théoriques multiples et hétérogènes, puisqu’ont été convoqués notamment les travaux de Choppin (2005, 2008), de Bautier et al. (2012), de Perret-Truchot (2015) ou de Bonnery (2015). Nos résultats s’appuient sur l’analyse fine de trente-neuf manuels. Si la recherche revêt un caractère exploratoire, les résultats qu’elle a induits invitent à prendre en compte ultérieurement un corpus plus important et suscitent des questions vives, tant du côté de la conception des manuels que de leur réception auprès des élèves, mais aussi des enseignants ou de leurs formateurs.

Introduction Physical literacy development during childhood is critical not only to favor sport performance outcomes but also to develop long term physical activity. It’s very important for children to move in a thinking way. Diversified activities are important to develop a large panel of fundamental motor skills and to stimulate perception. It is important for children to move, but it has to be done in a thinking way. Focus on inquiry With young children it is important to maximize active time, to develop fundamental motor skills and perception, to take into account inter-individual differences, to favor enjoyment, self-confidence and to guarantee optimal security. Most of these pedagogical challenges can be reached by appropriate instruction and by an adapted environment. Contribution There is clear evidence that modifying exercise facilities influence children’s behaviour with consequences for motivation, activity level and motor development. For 25 years a reflexive approach has been used at CEReKi (Liège, Belgium) in order to determine how indoor facilities can be modified with the aim to meet children needs and to favor motor development. Attractive circuits have been developed to stimulate specific motor skills (gymnastic, athletic or ball circuits). They were created to afford action possibilities and challenges for children to explore their own abilities for exercise. According to the children’s age and level of ability different pedagogical conditions can be provided: spontaneous play, guided discovery or structured games. Circuits have to be organised in such a way that children can do most exercises on their own. The arrangement of equipment offers multiple possibilities for movement, favouring active discovery for all children. The autonomy of children allows the teacher to move throughout the circuit and assist children by scaffolding their learning. Conclusion Our experience confirms that modifying indoor facilities is relevant for 3 to 8 years old children activities. [less ▲]

Background In the Congo Basin most of the light-demanding timber tree species display a deficit of natural regeneration which is a major handicap for sustainable production and certification. Whilst the majority of scientists investigate abiotic and biotic factors explaining that pattern, we hypothesize that tree population density or individual spatial isolation may also affect the tree fitness through inbreeding. In this study, we integrate ecological and genetic approaches to characterize the regeneration potential of a set of priority timber species by (i) estimating pollen dispersal distances at various tree population densities, and (ii) evaluating the impact of increasing spatial isolation on mating characteristics and tree fitness. The ultimate goal is the proposal of minimum population density that prevents inbreeding consequences. Method This ongoing study focuses on 10 timber species (Pericopsis elata, Milicia excelsa, Baillonella toxisperma, Entandrophragma cylindricum, E. utile, E. angolense, E. candollei, Afzelia bipindensis, Erythrophleum suaveloens, Terminalia superba). The data collection was carried out in the logging concession granted to Pallisco in Cameroon. We established two 400-ha plots, where all individuals (DBH > 10 cm) of the target species were inventoried and mapped. A sample of leave or cambium was collected for each of these individuals, as well as for seedlings to characterize patterns of gene flow using genetic tools (nuclear microsatellites). Dispersal agents were identified by direct observations and camera traps. Germination success was characterized in nursery for seeds collected on trees under an increasing isolation gradient. Results Main dispersal agents (wind, bat, rodent) and predators (rodent) were identified for all the species. The gene flow and germination data is still being analyzed and the main results will be presented in the poster. Conclusion Our data will allow characterizing the reproductive biology of a set of important timber species from the Congo basin. These information will strengthen sustainable forest management and the application of certification by adjusting harvesting norms through the use of scientifically-relevant data. In particular, we will tentatively define a maximum distance to be maintained between two adults to allow a qualitative reproduction. [less ▲]

This paper looks at the relationship between higher education ministers and the performance of the sector that they govern. Using an original panel dataset with the characteristics of European higher education ministers, we find that having a past experience in the sector leads to a higher level of performance, as measured by ranking data. Making a parallel with the literature about the impact of education on the educated, we discuss potential explanations behind the impact of this on-the-job learning experience. As we find that this characteristic has no impact on the spendings of the sector, we argue that this academic experience makes them more prone to introduce adequate reforms that makes the sector more attractive for top-researchers. Furthermore, we find that this result is driven by ministers with both sector-specific and electoral experience, the latter measured by a successful election at the regional or national level. This tends to show that political credibility should not be overshadowed by the importance of the sector-specific experience of ministers. [less ▲]

Le modèle dit de Sherbrooke développé par P. Loisel au Québec constitue le fondement des recommandations internationales en matière de programmes de retour au travail pour les travailleurs souffrant de lombalgie. Ce modèle a inspiré les recommandations belges et françaises (HAS 2013) en la matière. De nombreuses études explorent maintenant la possibilité d’une intervention précoce en milieu de travail – un des axes essentiels du modèle de Sherbrooke - dans d’autres problématiques de santé que la lombalgie, et notamment en cas de décompensation psychique. La combinaison d’une telle intervention avec les approches propres aux milieux de soin représente cependant un réel défi. Le programme de prévention secondaire de la lombalgie initié en Belgique en 2004 dans le cadre de l’assurance maladies professionnelles permet d’illustrer quelques-unes des difficultés à surmonter : information du public-cible (tout travailleur exposé à la manutention de charges et/ou aux vibrations corps-entier) et des médecins traitants concernés, mise en place d’une collaboration, jusque-là inexistante, entre médecins de revalidation et médecins du travail, sensibilisation des employeurs. Même la collaboration entre médecins se heurte à de sérieuses barrières. Elle implique en effet un dialogue et une relation de confiance entre le médecin traitant qui considère prioritairement la protection de son patient, le médecin du travail qui a à juger l’aptitude d’un travailleur pour une activité de travail définie et un médecin-conseil de la sécurité sociale dont la fonction centrale était encore récemment le contrôle du bien-fondé de l’arrêt de travail afin de préserver l’équilibre financier du système. La prévention de la désinsertion professionnelle devrait idéalement constituer un objectif commun à ces trois métiers médicaux mais il s’agit à l’évidence d’un chantier de longue haleine. La décision du gouvernement belge d’instaurer un trajet de réintégration multidisciplinaire au sein de l'Assurance Maladie pour tout assuré en arrêt-maladie depuis 3 mois a révélé, avant même sa mise en application prévue en 2016, les enjeux sous-jacents à un tel projet. Les négociations avec les partenaires sociaux ont abordé plusieurs questions. Veut-on promouvoir plus d’équité sociale, ou simplement limiter l’augmentation alarmante des dépenses d’invalidité ? L’entrée de l’assuré dans le trajet proposé va-t-elle se faire sur base volontaire, ou faut-il prévoir une sanction financière en cas de refus ? A quel médecin confier la direction du trajet ? Quelle place réserver au médecin du travail, et au médecin traitant ? Faut-il prévoir une responsabilisation financière de l’entreprise ou faire confiance à la bonne volonté des employeurs ?

Large granular lymphocyte and prolymphocytic leukaemias are rare chronic lymphoproliferative disorders. Large granular lymphocyte leukaemias consist of indolent disorders such as T-cell large granular lymphocyte and chronic lymphoproliferative disorder of natural killer cells and the very rare but aggressive natural killer cell leukaemia. Treatment of the indolent large granular lymphocyte leukaemias is necessary in case of symptomatic cytopaenias or non-haematological autoimmune disorders. First line therapy of these two disorders is based on three immunosuppressive drugs: methotrexate, cyclophosphamide and cyclosporine A. Aggressive natural killer cell leukaemia needs an L-asparaginase containing regimen as induction followed by allogeneic stem cell transplantation to prolong remission. T-cell prolymphocytic leukaemia always follows an aggressive course even after an indolent onset. The optimal treatment strategy should exist of remission induction with alemtuzumab intravenously followed by autologous or allogeneic stem cell transplantation. Treatment indications for B-cell prolymphocytic leukaemia follow the criteria described by the chronic lymphocytic leukaemia guidelines. After induction with fludarabine, cyclophosphamide, rituximab or bendamustine in patients without a p53 mutation and/or a 17p deletion and alemtuzumab in case of a p53 mutation and/or a 17p deletion, stem cell transplantation must be considered.

The energy transition corresponding to more electricity generation from variable and decentralized renewable energy sources requires the development of electricity storage technologies ranging from seconds to seasons. The power-to-fuel process provides a way to store electricity as a liquid energy vector, leading to high energy density and cheap long-term storage at ambient conditions. In the present work, we study the powerto- methanol process combining CO2 capture, water/CO2 co-electrolysis and methanol synthesis. An Aspen Plus model focussing on the electrolysis and methanol synthesis sub-processes is presented. The energy conversion efficiency is improved from 40.1 to 53.0 % thanks to heat integration using the pinch method. Further works include the experimental demonstration of this technology as well as the development of control strategies for its regulation. [less ▲]

In the frame of the ICON (Ionospheric Connection Explorer) mission of NASA led by UC Berkeley, CSL and SSL Berkeley have designed in cooperation a new Far UV spectro-imager. The instrument is based on a Czerny-Turner spectrograph coupled with two back imagers. The whole field of view covers [± 12° vertical, ± 9° horizontal]. The instrument is surmounted by a rotating mirror to adjust the horizontal field of view pointing by ± 30°. To meet the scientific imaging and spectral requirements the instrument has been optimized. The optimization philosophy and related analysis are presented in the present paper. PSF, distortion map and spectral properties are described. A tolerance study and alignment cases were performed to prove the instrument can be built and aligned. Finally straylight and out of band properties are discussed. [less ▲]

The optical calibration of the ICON-FUV instrument requires designing specific ground support equipment (GSE). The ICON-FUV instrument is a spectrographic imager that operates on two specific wavelengths in the UV (135.6 nm and 157 nm). All the operations have to be performed under vacuum UV light. The optical setup is based on a VUV monochromator coupled with a collimator that illuminates the FUV entrance slit. The instrument is placed on a manipulator providing fields pointing. Image quality and spectral properties can be then characterized for each field. OGSE, MGSE, optical calibration plan and vacuum alignment of the instrument are described. [less ▲]

Precision Livestock Farming (PLF) is spreading rapidly in intensive cattle farms. It is based on the monitoring of individuals using different kinds of sensors. Applied to grazing animals, PLF is mainly based on the recording of three parameters: the location, the posture and the movements of the animal. Until now, several techniques have been used to discriminate grazing and ruminating behaviors with accuracies over 90% on average, when compared to observations, providing valuable tools to improve the management of pasture and grazing animals. However, bites and jaw movements are still overlooked, even though they are of utmost importance to assess the animal grazing strategies for various pasture types and develop future techniques allowing better estimation of their intake. The goal of this review is to explore the possibility of monitoring the individual jaw movements and the differentiation of bites in grazing animals. For this purpose, (1) the mechanisms of forage intake in cattle are explained briefly in order to understand the movements performed by the cow, especially during grazing, (2) the various sensors that have been proposed to monitor jaw movements of ruminants such as mechanical sensors (pressure sensors), acoustic sensors (microphone) and electromyography sensors are compared and (3) finally the relationship between jaw movements, biting behavior and forage intake is discussed. The review clearly demonstrated the abilities of mechanical, acoustic and electromyography sensors to classify the difference types of jaw movements. However, it also indicated a wide range of accuracies and different observation windows required to reach these accuracies when compared to the observed movement. This classification purpose could lead to a better detection of more specific behavior, e.g. bite detection, and their exact location on pasture. [less ▲]

PROBA-3 [1] [2] is a Mission of the European Space Agency (ESA) composed of two formation-flying satellites, planned for their joint launch by the end of 2018. Its main purposes have a dual nature: scientific and technological. In particular, it is designed to observe and study the inner part of the visible solar corona, thanks to a dedicated coronagraph called ASPIICS (Association of Spacecraft for Polarimetric and Imaging Investigation of the Corona of the Sun), and to demonstrate the in-orbit formation flying (FF) and attitude control capability of its two satellites. The Coronagraph payload on-board PROBA-3 consists of the following parts: the Coronagraph Instrument (CI) with the Shadow Position Sensor (SPS) on the Coronagraph Spacecraft (CSC), the Occulter Position Sensor (OPSE) [3] [4] and the External Occulting (EO) disk on the Occulter Spacecraft (OSC). The SPS subsystem [5] is one of the main metrological devices of the Mission, adopted to control and to maintain the relative (i.e. between the two satellites) and absolute (i.e. with respect to the Sun) FF attitude. It is composed of eight micro arrays of silicon photomultipliers (SiPMs) [6] that shall be able to measure, with the required sensitivity and dynamic range as asked by ESA, the penumbral light intensity on the Coronagraph entrance pupil. With the present paper we describe the testing activities on the SPS breadboard (BB) and Development Model (DM) as well as the present status and future developments of this PROBA-3 metrological subsystem.

This paper presents the current status of ASPIICS, a solar coronagraph that is the primary payload of ESA’s formation flying in-orbit demonstration mission PROBA-3. The “sonic region” of the Sun corona remains extremely difficult to observe with spatial resolution and sensitivity sufficient to understand the fine scale phenomena that govern the quiescent solar corona, as well as phenomena that lead to coronal mass ejections (CMEs), which influence space weather. Improvement on this front requires eclipse-like conditions over long observation times. The space-borne coronagraphs flown so far provided a continuous coverage of the external parts of the corona but their over-occulting system did not permit to analyse the part of the white-light corona where the main coronal mass is concentrated. The PROBA-3 Coronagraph System, also known as ASPIICS (Association of Spacecraft for Polarimetric and Imaging Investigation of the Corona of the Sun) is designed as a classical externally occulted Lyot coronagraph but it takes advantage of the opportunity to place the external occulter on a companion spacecraft, about 150m apart, to perform high resolution imaging of the inner corona of the Sun as close as ~1.1 solar radii. The images will be tiled and compressed on board in an FPGA before being down-linked to ground for scientific analyses. ASPIICS is built by a large European consortium including about 20 partners from 7 countries under the auspices of the European Space Agency. This paper is reviewing the recent development status of the ASPIICS instrument as it is approaching CDR. [less ▲]

Metrology in diluted systems for space applications is one of the most important technology research fields that in recent years have raised increasing interest. Many applications of astronomical observation techniques, as coronography and interferometry get great benefit when moved in space and the employment of diluted systems represents a milestone to step-over in astronomical research. In this work, we present the Optical Position Sensors Emitter (OPSE) metrological sub-system on-board of the PROBA3. PROBA3 is an ESA technology mission that will test in-orbit many metrology techniques for the maintenance of a Formation Flying with two satellites, in this case an occulter and a main satellite housing a coronagraph named ASPIICS, kept at an average inter-distance of 144m. The scientific task is the observation of the Sun’s Corona at high spatial and temporal resolution down to 1.08R⊙. The OPSE will monitor the relative position of the two satellites and consists of 3 emitters positioned on the rear surface of the occulter, that will be observed by the coronagraph itself. A Centre of Gravity (CoG) algorithm is used to monitor the emitter’s PSF at the focal plane of the Coronagraph retrieving the Occulter position with respect to the main spacecraft. The 3 location target accuracy is 300m for lateral movement and 21cm for longitudinal movements. A description of the characterization tests on the OPSE LED sources, and of the design for a laboratory set-up for on ground testing is given with a preliminary assessment of the performances expected from the OPSE images centroiding algorithm.
