Cet article rend compte de la réflexion d’une équipe de formateurs à propos du mode d’évaluation à appliquer aux travaux d’enseignants en formation disposant au départ d’un bagage de compétences hétérogènes. Cette variété des compétences de départ a pour effet que les enseignants recourent de façon plus ou moins intensive à l’accompagnement pédagogique qui leur est proposé pour réaliser certaines tâches. Dans les cas d’un recours intensif à l’accompagnement se pose la question de la part de la note finale qui revient véritablement à l’enseignant-participant. Ces tensions entre équité et différentiation sont analysées dans le cadre du master complémentaire en pédagogie de l’enseignement supérieur organisé à l’Université de Liège (IFRES-FAPSE). Un outil est proposé pour les aborder : une grille visant à objectiver l’intensité de l’accompagnement dispensé/reçu et donc à apporter un éclairage plus nuancé sur les résultats de l’évaluation finale standardisée.

Une nouvelle intervention pédagogique a été mise en place en 2012-2013 en premier master. Basée sur les principes de la pédagogie inversée et de l’usage des boîtiers de votes, son objectif était d’améliorer la capacité des étudiants à réaliser un choix raisonné des médicaments antimicrobiens en situations cliniques simples en favorisant l’interactivité et la résolution de problèmes. Le dispositif et l’évaluation Trois heures de cours ont été consacrées à expliquer la démarche décisionnelle visant à optimaliser l’antibiothérapie et à présenter de manière magistrale une première famille d’antibiotiques. Des notes de cours détaillées et des résumés des points essentiels ont été mis à disposition des étudiants qui disposaient d’un boîtier vote électronique. Pour chaque situation, les questions majeures nécessaires à la structuration d’une démarche décisionnelle cohérente ont été sélectionnées par l’enseignant sur base des critères de choix des antibiotiques. Chacune d’elle était décomposée en sous-question pour lesquelles plusieurs solutions décisionnelles ont été proposées aux étudiants (Turning Point). A chaque étape, un vote suivi d’une discussion avec les étudiants était organisé, visant à comprendre le choix proposé par l’enseignant, discuter les choix alternatifs justifiés par les étudiants et à expliquer les erreurs décisionnelles mises en évidence par le vote. Une enquête de satisfaction a été réalisée. A l’examen oral de fin d’année, les connaissances et la capacité à structurer un schéma décisionnel ont été évaluées. Résultats et conclusion Le haut degré de satisfaction des étudiants, le sentiment d’un meilleur apprentissage de la démarche et la supériorité des notes d’examen des étudiants ayant suivi cette formation sont des éléments concordants en faveur d’un effet positif de l’intervention pédagogique sur la capacité décisionnelle des étudiants. Ce résultat a été obtenu par la combinaison de la pédagogie inversée, couplée à l’usage des boîtiers de vote et à la conception de questionnaires structurés pour discuter les démarches décisionnelles de manière interactive au sein d’une cohorte importante d’étudiants.

Galleries drilling leads to damage propagation, fracturing and properties modifications in the surrounding medium. The prediction of the damaged zone behaviour is an important matter and needs to be properly assessed. To do so the fractures can be modelled using shear strain localisation. The coupled local second gradient model is used under unsaturated conditions to correctly model the strain localisation behaviour. The permeability evolution and the rock desaturation due to air ventilation in galleries are considered. Finally, a hydro-mechanical modelling of a gallery excavation in Callovo-Oxfordian claystone is performed leading to a fairly good representation of the damaged zone. [less ▲]

Le cancer constitue une maladie fréquente en Belgique puisqu'un homme sur trois et une femme sur quatre sont confrontés à la maladie avant l'âge de septante-cinq ans (Fondation Registre du Cancer, 2008). La détection précoce et l'amélioration des traitements du cancer, généralement une combinaison de chirurgie, radiothérapie, chimiothérapie, hormonothérapie et thérapie ciblée, ont permis une augmentation du taux de survie. Cependant, ces traitements peuvent être à l'origine de nombreux effets secondaires, non seulement précoces, mais également tardifs, réduisant la qualité de vie. De nombreux programmes de réhabilitation après cancer sont basés sur la psychothérapie et le support social uniquement, or ceux-ci n'agissent généralement pas sur les problèmes physiques encourus par les patients tels que la fatigue, la prise de poids et la diminution des capacités fonctionnelles. C'est pourquoi nous émettons l'hypothèse qu'une revalidation physique, associée à des séances psycho-éducatives et constituant ainsi une prise en charge multidisciplinaire, permettrait d'améliorer d'autant plus la qualité de vie et le bien-être tant physique que psychologique des patients ayant été traités pour un cancer.

In dealing with monuments of small scale and local importance historical social, cultural, religious or political networks can be detected once we transcend the solely focus on the object. At the same time those buildings remain to have, up to today, an impact on the social and cultural stratification and an engaged community involvement is very often present. These building are often considered modest heritage although they show great craftsmanship. There is a well-known framework to cope with the material aspects of conservation and restoration of these buildings, but a framework for the intangible layers is lacking. In the tackled heritage societal value was important and crucial. The buildings became collective by their use, local significance or representation. They became beacons, points of reference or meeting points. They form complex spaces of experiences, places of attachment and recognition. Within managing heritage one is hardly focusing on the ‘nameless local’, i.e. the person or social groups that in most cases appropriated the building and its significance ‘in the meantime’, the time between the original occupation and the project of adaptive reuse of the monument. Forgetting about this informal actor is not difficult as they are often invisible or disappearing amid all other elements, especially if one focuses only on the materiality of the building as a historic data. This is enforced by the fact that there are no approved ways for it tracing this. In this contribution some of the tested concepts and tools discovered in the search for and the development of strategies to develop historical buildings in their context differently by reading, mapping, unveiling and understanding their societal meaning for the individual and for the local community will be described.

Be stars are B-type stars near the main sequence which undergo episodic mass loss events detected by emission lines, whose line shape and intensity vary with a timescale of the order of decades. Spectroscopic observations show a large rotation velocity such that one of the prevailing scenarios for the formation of the equatorial disk consists in an increasing equatorial rotation velocity to the break-up limit where gravity is challenged by the centrifugal force. We investigate here a new scenario recently suggested by Ishimatsu & Shibahashi (2013), in which the transport of angular momentum through the photosphere would be achieved by leaky waves, keeping the rotation velocity still below the break-up limit.

It has been proposed that the variability seen in absorption lines of the O6Ief star λ Cep is periodical and due to non-radial pulsations (NRP). We have obtained new spectra during six campaigns lasting between five and nine nights. In some datasets we find recurrent spectral variations which move redward in the absorption line profile, consistent with perturbations on the stellar surface of a rotating star. However the periods found are not stable between datasets, at odds with the NRP hypothesis. Moreover, even when no redward trend is found in a full dataset of an observing campaign, it can be present in a subset, suggesting that the phenomenon is short-lived, of the order of a few days, and possibly linked to transient magnetic loops.

Early-type stars are well-known to be sources of soft X-rays. However, this high-energy emission can be supplemented by bright and hard X-rays when magnetically confined winds are present. In an attempt to clarify the systematics of the observed X-ray properties of this phenomenon, a large series of Chandra and XMM observations was analyzed, over 100 exposures of 60% of the known magnetic massive stars listed recently by Petit et al. (2013). It is found that the X-ray luminosity is strongly correlated with mass-loss rate, in agreement with predictions of magnetically confined wind models, though the predictions of higher temperature are not always verified. We also investigated the behaviour of other X-ray properties (absorption, variability), yielding additional constraints on models. This work not only advances our knowledge of the X-ray emission of massive stars, but also suggests new observational and theoretical avenues to further explore magnetically confined winds. [less ▲]

Although playing a key role in the understanding of the supernova phenomenon, the evolution of massive stars still suffers from uncertainties in their structure, even during their ``quiet'' main sequence phase and later on during their subgiant and helium burning phases. What is the extent of the mixed central region? In the local mixing length theory (LMLT) frame, are there structural differences using Schwarzschild or Ledoux convection criterion? Where are located the convective zone boundaries? Are there intermediate convection zones during MS and post-MS phase, and what is their extent and location? We discuss these points and show how asteroseismology could bring some light on these questions. [less ▲]

A recent photometric survey in the NGC 3766 cluster led to the detection of stars presenting an unexpected variability. They lie in a region of the Hertzsprung-Russell (HR) diagram where no pulsation are theoretically expected, in between the δ Scuti and slowly pulsating B (SPB) star instability domains. Their variability periods, between ~0.1-0.7 d, are outside the expected domains of these well-known pulsators. The NCG 3766 cluster is known to host fast rotating stars. Rotation can significantly affect the pulsation properties of stars and alter their apparent luminosity through gravity darkening. Therefore we inspect if the new variable stars could correspond to fast rotating SPB stars. We carry out instability and visibility analysis of SPB pulsation modes within the frame of the traditional approximation. The effects of gravity darkening on typical SPB models are next studied. We find that at the red border of the SPB instability strip, prograde sectoral (PS) modes are preferentially excited, with periods shifted in the 0.2-0.5 d range due to the Coriolis effect. These modes are best seen when the star is seen equator-on. For such inclinations, low-mass SPB models can appear fainter due to gravity darkening and as if they were located between the δ Scuti and SPB instability strips. [less ▲]

Avant d'être l'affaire des courants de l'éducation nouvelle, la pédagogie par projet était présente dans les discours de formation d'architecture italienne dès le 16e siècle. Aujourd'hui, elle s'inscrit parmi les multiples approches d'une pédagogie différenciée et est utilisée dans plusieurs disciplines, des arts aux sciences, en passant par l'ingénierie et l'administration. Plusieurs écrits existent à son sujet, mais peu s'attardent aux pratiques d'évaluation des apprentissages qu'elle génère. Pourtant, celle-ci est l'un des aspects les plus complexes de l'enseignement et le plus prenant puisque le professeur en est l'unique responsable et qu'il occupe près de la moitié de sa tâche (Laurier, Tousignant et Morrissette, 2005). Dimension fondamentale, et parfois difficile, dans le parcours de l'apprenant, l'évaluation des apprentissages impose actuellement un changement de culture important pour les professeurs, particulièrement lorsqu'il est question de pédagogie par projet. Pour certains d'entre eux, souvent peu formés en enseignement, mais possédant une expérience du métier reconnue, l'évaluation se limite au projet et à sa présentation devant un jury et les pairs au détriment de la qualité de la démarche et surtout des apprentissages réalisés (Allal, 2013; Beattie, 2006; Gaillot, 2009 ; Romainville, 2011). Dans la formation d'architecte, la pédagogie par projet fait partie intégrante du processus d'enseignement, d'apprentissage et d'évaluation. En atelier de projet de 3e bachelier à l'ULg, l'évaluation des apprentissages exclusivement orientés sur le projet a mené, après plusieurs années d'expérimentations, à la création de dispositifs adaptés et spécifiques. S'appuyant sur les principes clés et actuels en évaluation des apprentissages, ces dispositifs tentent de mettre en avant-plan un souci de concordance entre le contenu à enseigner et les méthodes utilisées. Croisant les regards théoriques et pratiques sur le sujet de l'évaluation de performances complexes intégrant créativité et innovation, un bilan des expériences sera établi et tentera de dégager des pistes de régulations pour continuer d'élever le niveau de validité du processus présenté.

Since 2000, we can observe important changes in traditional production systems of coastal communes in North Vietnam. Faced with relatively low incomes, rice farms converted the surfaces available to them in aquaculture ponds. These are difficult to reverse conversions were carried out by farmers seeking to improve family income in areas of relatively low rice productivity. These changes have had a significant impact on the revenues generated in coastal villages with changes in work organization and the upstream business opportunities for feed plants. This type of family aquaculture has grown rapidly to meet domestic demand but also to export markets. Faced with these voluntary initiatives, the Vietnamese authorities have had difficulties to coach and support these new producers in sustainable development schemes for fresh water or brackish water aquaculture. In addition, climate change could significantly affect these areas particularly exposed to rising sea waters. Moreover, aquaculture producers respond to logic relatively isolated individual entrepreneurs. They deliver their products to many collectors who engage strong competition. This is particularly true at the sub-sectors supplying the domestic market. The Vietnamese marketing system for aquaculture products is generally considered competitive and efficient. It involves different stakeholders (collectors, dealers, wholesalers and processors) that develop often difficult short-term strategies to understand and which do not permit a good traceability of production. At producer level, understanding of market mechanisms is very limited which makes it difficult to decision support for investments and marketing. Meanwhile, producers are exposed to high price volatility. Small producers oriented towards the local market are particularly exposed and vulnerable to this issue and it is important to understand the strategies that can be implemented to ensure against this form of risk. In this context, this paper describes two initiatives conducted in the Northern area of Vietnam to strengthen the sustainability of clam’s farms and supported by researchers from Vietnam National University of Agriculture.

Locality and place making as elements of social sustainability play a significant role in a world of growing globalization. More and more researchers and professionals realize that the identity of small communities is also constructed by modest heritage, responsible for a large part of the quality and social cohesion. Once we focus on the historical, social, cultural, ecological and physical meshwork, we transcend the solely focus on the object to explore the physical, emotional and experiential realities of place and how these are rooted in the individual and collective memory as they unfold in the everyday life. In the creation of a sustainable and resilient society the meaning and appropriation of that heritage is too important and too complex to restrict the significance of it purely to the artefact itself with its acknowledged architectural, historical or archaeological values. How can new meaning of place be enacted, created and negotiated in current times of migration and mobility? What is the status and role of modest heritage in small communities today? Does it still play a considerable role in the identity, quality and social cohesion of a region? How do we explore the intangible dimension of the tangible? How do we deal with the intangible and informal aspects of heritage? This paper concentrates on these issues in the complex urban countryside of the region of Flanders (Belgium). Flanders is a highly dense and post-industrialized area where the countryside is under an urbanized pressure. Within the fabric we detect numerous small-scale heritage as chapels, parsonages, ice-cellars, donjons, square farms and wind- and watermills. Possible relationships of heritage with its context will be tackled, explored and tested in different layers through particular cases within the strategy of storytelling as a spatial practice.

This paper scrutinizes various dependency-based representations of the syntax of function words, such as prepositions. The focus is on the underlying formal object used to encode the linguistic analyses and its relation to the corresponding linguistic theory. Two types of representation are proposed for the encoding of syntactic properties and applied for function words. Although the mathematical object introduced here encodes a dependency-based analysis, it does not consist in a tree. It is rather more general than a graph (it allows edges to be vertices of other edges) and is called a polygraph. [less ▲]

Neonatal hypoxic-ischemic brain injury remains a main problem of perinatal medicine. About 20% of affected newborns die in the postnatal period, and an additional 25% will sustain childhood disabilities mostly in the form of motor and cognitive delays. The nature of the deficits is dependent on the gestational age and severity of the insult, though it is s seldom reported in preterm infants. No medical treatment provides important neuroprotection against HIE. Studies in animal models of HIE may provide important information for the development of treatment for this pathological condition. Estetrol (E4) is a recently described estrogen with four hydroxyl-groups that is synthesized exclusively during pregnancy by the human fetal liver. In this study, we defined the antioxidative effect of E4 in primary hippocampal cell cultures taken from newborn rat pups (in vitro) and evaluated its neuroprotective and therapeutic potency in neonatal HIE model of the immature newborn rat (in vivo). Lactate Dehydrogenase (LDH) and cell survival (MTS) assays were performed on primary neuronal cell cultures. Rat pups body temperatures were examined along with their body and brain weights. Brains were studied at the level of the hippocampus and cortex. Intact cell counting and expressions of markers for neuronal cell viability (microtubule-associated protein-2 (MAP-2)), neurogenesis (doublecortin (DCX)) and angiogenesis (vascular-endothelial growth factor (VEGF)) were evaluated by histo- and immunohistochemistry. The serum levels of two markers of brain damage (S100B and glial fibrillary acidic protein (GFAP)) were measured by ELISA. Our results demonstrate that E4 has a significant neuroprotective and therapeutic dose-dependent effects. Estetrol has powerful antioxidative and cell survival effects in vitro. It decreases the early gray matter loss and promotes neuro- and angiogenesis in vivo. Estetrol treatment has no effects on body weight, brain weight or body temperature. Taken together, Estetrol might become an important safe and physiological substance to treat neonatal HIE. [less ▲]

Recycled concrete aggregates (RCA) are mainly composed of an intimate mix between natural aggregates and cement paste and the complete separation between these two phases is difficult. Cement paste generally presents a much larger porosity than natural aggregates, the content and the physicochemical properties of cement paste therefore have a large influence on the properties of RCA. Any method seems to be adapted to the characterization of cement paste content (CPC) in fine recycled concrete aggregates (FRCA) especially for RCA containing calcareous aggregates. A simple method based on the dissolution of the cement paste in a solution of salicylic acid in methanol was specifically developed to estimate the cement paste content of RCA. Results showed that salicylic acid dissolution method can dissolve most phases of hardened Portland cement paste such as Portlandite, ettringite and C-S-H without dissolving siliceous and calcareous aggregates. The experimental results for two neat Portland cement pastes (white cement paste and grey cement paste) showed that the soluble fraction in salicylic acid (SFSA) was equal to the cement paste content for white cement and slightly lower for the grey cement. The SFSA was measured for different types of RCA. The RCA manufactured in the laboratory whose composition is fully known and three RCA manufactured from industrial crushing platforms have been characterized. Whatever RCA used in our study, SFSA varies almost linearly with the average particle size. A linear relationship was obtained between the water absorption coefficient and SFSA. This relationship allowed us to accurately determine the water absorption coefficient of the smallest granular class 0/0.63mm. [less ▲]

An adhesion in repair system is one of the most important factors that affect the repair efficiency. The elaboration of reliable nondestructive method for an adhesion mapping is one of the most important tasks. A majority of NDT methods mentioned in EN 1504-10 and ACI Concrete Repair Manual for assessment of concrete structures are based on propagation of stress waves. However, these investigations are rarely focused on evaluation of bond strength. Repair system is difficult to test with NDT methods because of many factors influencing stress wave propagation. In this paper the effect of a quality of concrete substrate on propagation of stress waves in repair system and their influence on possibility of estimation of the bond strength is discussed.

The primary objective of this paper is to explore the influence of socio-demographic and contextual variables on the multimodal character of public transit journeys. Accounting for multimodality in public transit journeys is important from a demand modeling point of view, especially in the assessment of new projected public transit infrastructure. To meet the objective, data from the national household travel survey of Flanders (Belgium) is analyzed. Based on 2,202 public transit journeys, the main public transit mode choice (bus/tram/metro or train) and access/egress mode choice are simultaneously estimated using a multinomial logit model, and by explicitly making a distinction between unimodal and multimodal transit journeys. The results indicate that various socio-demographical (e.g. age, gender, level of education, household income) and contextual factors (e.g. journey distance, journey motive, urbanization degree, car availability) significantly influence the joint decision process. Total journey distance and car availability are identified as the most important explanatory variables. In terms of model performance, the model appears to yield satisfactory predictions, justifying the integration of the model in more general demand modeling frameworks. [less ▲]

In recent years the increasing interest for eco-sustainable building materials and the rising issue of plastic waste disposal are leading to the engineering of new composite construction materials incorporating post consumer recycled plastics, able at the same time to meet new standard requirements, in terms of energy efficiency, and to reduce the consumption of natural resources. In the context of these issues, we have performed investigations on the effects of the addition of foamed artificial aggregates deriving from recycled plastic materials to a cementitious mortar. For this purpose, several mortar samples containing natural sand and different amounts (10, 25 and 50 % by volume) of foamed recycled plastic wastes were produced. The foaming of the recycled plastic waste was performed in laboratory by a foam extrusion process using a blowing agent (2 wt.%). An artificial aggregates particle size distribution similar to standard sand was used. Rheological and physical properties of lightweight mortar were studied. The improved surface roughness of foamed plastic aggregates ensures a more continuous interface and the presence of surface pores provides interlocking effect with cement paste. Replacement of natural sand by artificial aggregates produces a lightweight mortar but reduces mechanical properties. [less ▲]

Forage legumes (FL) are used in tropical countries to feed pigs, either by reducing allowance of well-balanced diets and supplementing with FL or by incorporating FL in unbalanced fibre-rich diets. The impact of both strategies on animal and economical performances was studied in 2 growth experiments. In Exp. 1, 4 groups of 8 growing pigs (25.5 +- 4.2 kg) were fed under one of 4 dietary treatment: a well-balanced diet (CONTROL) ad libitum or 80% of the ad libitum level of CONTROL + ad libitum freshly cut foliage of one of 3 FL species (Vigna unguiculata, Stylosanthes guinanensis, or Psophocarpens scandens). Similarly, in Exp. 2, 4 groups of 6 pigs (22.6 +- 3.7 kg) were fed one of 4 experimental diets: the well-balanced diet (CONTROL), an unbalanced traditional diet rich in fibre and made of bran, brewers grain, and corn (TRAD) or 80% TRAD diet supplemented with 20% of one of 2 FL hays (V. unguiculata or S. guinanensis). Animals were regularly weighed and feed intake was monitored. After 90d, animals were slaughtered and carcass composition and economic traits were recorded to calculate production costs and economical value. In addition, nutritive value of the FL and the diets was assessed by means of an in vitro model of the pig digestive tract combining an enzymatic hydrolysis to a fermentation with a fecal inoculum. Results indicate that pigs fed diets with FL (Exp.1) and TRAD with and without FL (Exp.2) had reduced ADG, final live and carcass weights (P<0.05) compared to CONTROL pigs. Surprisingly , dry matter intake (DMI) was also reduced by 10% with those diets compared to CONTROL (P<0.001) in both experiments. In Exp. 1, FCR and carcass dressing were not affected by the 20% reduction in CONTROL diet and supplementation with fresh FL, while in Exp. 2 those parameters were negatively affected in TRAD with and without FL compared to CONTROL pigs. In vitro data showed that differences in nutritive values explained most differences in growth performances and carcass traits, but not the decrease in intake, since passage rate and voluntary intake are not taken into account in the in vitro model. Economical assessment showed that fresh foliage of FL could increase incomes, as long as their production costs remain marginal, but the incorporation of FL hays could not improve economical performances in pigs fed traditional unbalanced fibre-rich diets.

The work reported in this paper is part of a wider research program intended to provide the repair industry with improved fundamental knowledge to implement rational design methods and rules for repairs. In that regard, there is a strong need to study the fundamental relationships and parameters that underlie the repair compatibility concepts, in particular those relating to dimensional compatibility. In the first part of the paper, classical formulas derived for thick cylindrical specimens were used to analyze the tensile stress buildup in annular restrained shrinkage test specimens, taking into account the restraining conditions the investigated ring test method and the individual concrete properties/phenomena determined experimentally (elastic modulus, creep coefficient, drying shrinkage deformation). By comparing the ring test results with the calculated tensile stresses, the validity and accuracy of the theoretical approach could be appraised. A quantitative approach for the evaluation of the performance of concrete repair in terms of dimensional compatibility was then developed. Derived from the basic strain balance approach (ratio between the total deformability in tension and the drying shrinkage deformation), a parameter referred to as dimensional compatibility index (CI) was introduced in order to analyze the evolution of dimensional compatibility as a function of time for a given concrete mixture, taking into account the actual degree of restraint in the element. Compatibility index evolution curves were calculated for various repair concrete mixtures in order to highlight material behavior relating to composition parameters and temperature. As it requires the evaluation of a limited number of individual properties that are for most readily available (i.e. strength, elastic modulus, shrinkage), the compatibility index expressed in terms of deformation carries a lot of potential as a relatively simple and convenient analytical tool for assessing the cracking sensitivity of concrete repair materials. Overall, it can be stated that a good correlation was found between the ring test results and the tensile stress values calculated based on individual concrete properties / phenomena and that the proposed calculation method lays ground for evaluating quantitatively the dimensional compatibility of repair materials and defining suitable performance criteria.

Algorithmic and computer programming in the bachelor’s degree is a course that demands a large involvement of students in performing non-standard exercises. This practical aspect is incompatible with classical ex cathedra course. It is the reason why we implement a blended learning approach much more responsive to students in a bachelor class of Bio Engineering at the Gembloux Agro Bio Tech Faculty (University of Liege, Belgium). This course alternates theoretical classes, take-home lessons with the help of online pedagogical resources and video and debriefing sessions where students have the possibility to benefit from teacher’ support. In doing so, the students are better prepared for the examination. They also gain in confidence and motivation. The teacher no longer simply transmits the knowledge but assists the students in their reflection process and their mastering of programming tools [less ▲]

We describe a new gait segmentation method based on the continuous wavelet transform to identify stride-by-stride gait cycles from measurements of foot-mounted three-dimensional (3D) accelerometers. The detection of such gait cycles is indeed a crucial step for an accurate extraction of relevant gait events such as heel strike, toe strike, heel-off, and toe-off. We demonstrate the ability of this segmentation method, used in conjunction with a validated extraction algorithm, to calculate the following gait (duration) parameters for each gait cycle during the gait of a healthy young subject and of an elderly subject with Parkinson’s disease (PD) in OFF and ON states: durations of (1) loading response, (2) mid-stance, (3) push-off, (4) stance, (5) swing, (6) stride, (7) step, and (8) double support phases. The experimental results show that the proposed method can extract relevant refined gait parameters to quantify subtle gait disturbances in subjects with PD. [less ▲]

Technology assessment (TA) and TA-like activities in countries like Japan have a unique history and continue to play a role in contemporary science, technology, and innovation (STI) processes. The aim of the discussion of TA’s experience in East Asia is how STI governance is locally enacted in Asian knowledge-driven economies, as TA activities develop in conjunction with STI policies and programs. To render these processes, policies, and programs visible and to understand their implications for STI governance, a panel at the Berlin conference on TA discussed contributions that described and conceptualized, for example, how TA activities have emerged in Asian knowledge-based economies (KBE), in which particular forms (e.g., academic and parliamentary TA programs), to which technologies and/or actors they are linked, and which methods are used and why. The panel also sought to compare and contrast how TA is (or is not) institutionalized in Asian countries and regions, and to point to prospects for expansion of TA capacity. In doing so, the panellists placed the development of TA in a historical, sociological, and comparative perspective, and opened space for critical reflection on the potential, problems, and limitations associated with initiating TA in Asia and with KBEs overall.

How could we link together digital dictionaries which have no common lexical units, but deal with the same linguistic area? And how could we do that automatically, in order to ensure that all future updates of these dictionaries are taken into account in the linking process? This contribution exposes the solutions that we propose in the field of French and Gallo-Romance historical lexicography. The digitalisation currently in progress of a work of scientific reference, i.e. the Französisches Etymologisches Wörterbuch (FEW), gives us a mean to link together other dictionaries, such as the Dictionnaire Etymologique de l’Ancien Français (DEAF), the Dictionnaire du Moyen Français (DMF), the Anglo-Norman Dictionary (AND), or the Atlas Linguistique de la Wallonie (ALW), through the use of the references of these dictionaries to the FEW. Concrete examples of linking lexical data are discussed in this context. We also describe a simple peer-to-peer protocol allowing e-dictionaries to be automatically linked in a distributed way using the references of their articles. An implementation based on a simple REST API is suggested to let teams maintaining different e-dictionaries keep their own technologies and data schema. [less ▲]

Face à une situation de manque de terre et de pression démographique sans aucune amélioration des techniques de production, le choix des cultures à pratiquer permettant de rentabiliser la petite surface agricole disponible devient donc crucial pour les producteurs de Matongo en particulier et du Burundi en général. C'est dans ce contexte que le fruit de la passion est intégré dans les systèmes de production de certains ménages de Matongo dans le but d'améliorer leurs conditions de vie grâce à un supplément de revenu. Vu l'état actuel de la vulnérabilité de l'agriculture et de l'économie dans cette commune, il s'avère important de connaître les contraintes rencontrées par les adoptants du fruit de la passion en tenant compte de l'environnement dans lequel se pratique sa culture.

The objective of this paper is to study the effect of structural dissipation on the dynamic response of tape springs using experimentally-validated finite element models. In order to reach this goal, an experimental set-up is built. It consists of two tape springs connected to a fixation support and a dummy panel. The data are collected through a force plate and a 3D motion analysis system. The post-treatment of the experimental results and a comparison with a finite element model show that the Kelvin-Voigt model gives a fair approximation of the structural damping for small oscillations, however, more advanced model should be considered in future works for a better understanding in case of large displacements.

This paper presents an explicit multi-model predictive controller (MMPC) for a waste heat recovery system (WHRS) mounted on a heavy duty truck engine. WHRS based on the Rankine cycle principle attracts a lot of interest in the heavy duty industry, over the past few years, to decrease the fuel consumption and reach the future pollutant emissions standards. Control issues have still to be faced before the integration of such a system into a vehicle. Model predictive controllers suits really well for our control purpose due to their ability to handle online optimal control problem. This paper focuses on the development of an explicit control law based on MMPC with aim to control the fluid temperature at the inlet of the expansion machine in order to increase the system performance and the reliability.

Over the past decades, researchers studying adult metacognition have placed a heavy emphasis on how expectations and naïve theories about memory functioning can improve memory accuracy through the implementation of some metacognitive rules. By contrasts, however, research on metacognition in children has only recently started to pay attention to the influence of these heuristic-based judgments on decision making. Generally, the results of these studies indicate that memory decisions are already based on some heuristics by the ages of 7-8 years. Thus far, the question of whether younger children can do the same has widely gone unexamined. The present experiment investigates whether young children are able to reduce their false recognitions rate after distinctive encoding through the implementation of a strategic metacognitive rule. Specifically, we examine the use of a retrieval strategy called the distinctiveness heuristic whereby people infer that an event has not occurred when they cannot remember expected memorial information about it. Seventy-two children, aged 4, 6, and 9 years, studied two lists of unrelated items. One of these lists was visually displayed (picture/dictinctive condition) while the other was presented auditorily (word/no-distinctive condition). After each study phase, participants completed recognition tests. Finally, they answered questions about their explicit knowledge of the distinctive-encoding effect. The results revealed that even the youngest children in our sample showed a smaller proportion of intrusions in the picture condition than in the word condition. Furthermore, the findings of the signal detection analyses are consistent with the hypothesis that the lower rate of false recognitions after picture encoding results from the implementation of a conservative response criterion based on the participants’ metacognitive expectations (distinctiveness heuristic). Moreover, the absence of correlation between children’s explicit knowledge of the distinctiveness rule and their effective use of this metacognitive heuristic seems to indicate that its involvement in memory decisions could be mediated by implicit mechanisms.

Since migration was mentioned as a pattern of development, the debates have never ended. In Vietnam, the industrial zone has been developed rapidly for more than 20 years. However, the rate of migrant labor is high. Based on push and pull theory of migration the study is to find the reasons that push or pull rural labors to migrate to industrial zones. By surveying 190 migrants in industrial zone, the study found that the employment in the zones is not stable in the long run. Migration not always driven by poor economic condition of the houhsehold in the areas of origin, it is the way of life of young rural labor and the migrants in the zones seem to be pulled rather than pushed.

Cooperative organisations play an important role in the peacebuilding efforts undertaken in the wake of the Rwanda genocide in1994. The genocide tore apart and destroyed large parts of the country’s socio-economic and institutional foundations, its consequences are still evident. Coffee is the main source of income for approximatively 500.000 households. The paper aimed to analyze the impact of coffee cooperatives and the coffee washing stations in the peacebuilding socio-economic changes of coffee farmer’s members in Huye District, Southern Province of Rwanda. A research surveyed selected 70 small coffee farmers from 3 cooperatives to measure socio-economic development of coffee washing stations on the growers. Results reveal that cooperatives increase production and improve the socioeconomic households’ income (86.5%). Jobs are created for women and girls especially during the harvesting and the coffee processing (98.7%). When farmers are working together, a synergy is created among them, by disucussion, exchanging experiences, which avoide discrimination, conflict, division between antagonist ethnic groups Hutu and Tutsi (67.1%). Results reveal that coffee cooperatives promote a spirit of understanding each other and the tolerance between farmers (72.3%). Cooperatives provide loans to the members through the “rotating funds: Ibimina”. They also educate members through vocational trainings by enhancing and empowering farmers especially women and girls (97.1%). This is evidenced by the provision of adequate shelter, the observation of human rights, access to the medical insurance, school fees for children, undertaking entrepreneurial activities, unity and reconciliation between members, participating in the household’s incomes allocation. Cooperatives uses various strategies in peacebuilding such as working together to construct new schools and houses, land inheritance for women, clubs for peacebuilding and visiting each others (74.3%).

The notion of citizenship rests on the cleavage between national and international law as a matter predominantly shaped by state's internal acts, in accordance with limits determined by the state's interrelations with other states and rules of international law. The respective dichotomy generates further branching of the notional structure, making it multilayered, multidimensional and fluid. The simplified definition of citizenship conceptualises it as a real and effective link between the state and an individual, however, in social reality the notion transcends the respective formal perception and interferes with conceptions of identity, belonging and sentiments. With the aim of positioning citizenship within the domain of contemporary international human rights protection, this paper focuses on the analysis of jurisprudence of the European Court of Human Rights which has in several of its recent judgments provided for an original interpretation of the right to citizenship, subsuming it under the ambit of Article 8 of the Convention for the Protection of Human Rights and Fundamental Freedoms on the right to private and family life. Although Conventional norms do not grant the right to citizenship expressis verbis, an insight into three judgments (Genovese v. Malta, Mennesson v. France and Jeunesse v. the Netherlands) demonstrates that the Court's innovative interpretation of Article 8 has proved that flexible notions of private and family life are comparable enough with citizenship to embrace the aspects of a person's social identity which make up the essence of the concept of citizenship.

Selon la loi de Pareto, 80 % des effets sont produits par 20 % des causes. Transféré au contexte universitaire, on dira que les petites différences de comportement, notamment langagier, entre enseignants conduisent à des effets sur les étudiants qui peuvent être fortement diversifiés. C’est cette observation qui nous a encouragé à développer les études micropédagogiques , c’est-à-dire l’observation fine de l’activité des enseignants pour saisir ce qui la caractérise et la rend plus ou moins « efficace » (le terme étant évidemment relatif et à définir en fonction des contextes, des objectifs poursuivis et des apprenants). Le principe méthodologique de l’étude micropédagogique consiste donc à combiner (1) l’analyse fine de l’activité enseignante et (2) ses effets auprès des apprenants. Dans le cadre de cette communication, nous présentons l’intégration d’un dispositif de recherche et d’un dispositif d’apprentissage situés dans cette perspective d’approche micropédagogique. Durant plusieurs cours, deux caméras filment simultanément d’une part l’enseignant qui réalise un exposé et d’autre part le groupe d’étudiants. Lors de la séquence pédagogique suivante, les apprenants visionnent le double film (en split screen) et le commentent collectivement, en reliant les observations sur l’activité de l’enseignant et les effets que cela a eu sur leur dynamique d’apprentissage. Il en ressort que plusieurs actions du formateur ont fort impact sur l’apprentissage et la motivation, notamment : les modes de gestion du groupe, la formulation des questions, les modes de réactions de l’enseignant aux interventions des participants, les types d’exemples choisis, l’utilisation des analogies ou encore la projection dans le passé et dans le futur. Selon la manière de procéder de l’enseignant, ils contribueront plus ou moins à l’apprentissage et à la dynamique motivationnelle des étudiants. Par cette démarche de recherche, les apprenants produisent à la fois de la connaissance scientifique et développent leur propre apprentissage sur les contenus de l’étude micropédagogique. [less ▲]

Outil d’évaluation interactive, les boitiers de vote, apparaissent comme un outil propice à la mise en œuvre d’une pédagogie favorisant l’engagement de tous les étudiants dans le cours et en permettant une régulation du processus enseignement/apprentissage « on line ». La littérature déjà abondante apporte des éléments qui vont dans ce sens bien que certains résultats viennent également questionner les bénéfices cognitifs des BVE. Parallèlement aux comptes-rendus d’expérience, les recherches, essentiellement quantitatives, s’intéressent davantage aux appréciations des acteurs et aux performances des étudiants qu’à l’observation des usages en situation. Afin d’appréhender l’utilisation effective des BVE dans les cours, des études de cas approfondies ont été conduites à l’université Blaise Pascal selon un protocole de recueil de données reposant sur des entretiens conduits avec les enseignants avant et après des séances de cours observées et filmées ainsi qu’un recueil des points de vue des étudiants. A partir des résultats obtenus, nous avons construit un schéma théorique visant à modéliser les dimensions structurantes de l’apprentissage actif avec les boitiers qui sera présenté lors de la communication.

In the context of Renovation in Vietnam, there is a large wave of peasant migrants moving out of agriculture to find the jobs in nonfarm sectors. The interactions of migration and agricultural production can be seen in different aspects. This research focused on behaviors of farm households. There are the less evidences of labor shortages at both production and hiring labors. Maintenance at reasonable level rather than rather than the abandonment or expansion of agricultural activites is likely the more popular trend. Although remittance presented as a stable financial inflow ensures the sufficient cash which would strenghten the rural households' livelihoods security and reduce force of selling agricultural production for cash, agriculture production is still fundamental livelihood activity for household security.

Fast rotation in massive stars is predicted to induce mixing in their interior, but a population of fast-rotating stars with normal nitrogen abundances at their surface has recently been revealed (Hunter et al. 2009; Brott et al. 2011, but see Maeder et al. 2014). However, as the binary fraction of these stars is unknown, no definitive statements about the ability of single-star evolutionary models including rotation to reproduce these observations can be made. Our work combines for the first time a detailed surface abundance analysis with a radial-velocity monitoring for a sample of bright, fast-rotating Galactic OB stars to put strong constraints on stellar evolutionary and interior models.

Difficulties in everyday life activities are core features of persons diagnosed with schizophrenia, and in particular for those activities requiring multitasking capacities. Multitasking refers to activities (e.g. preparing a meal) where the person has to: (a) carry out and alternate between different tasks that vary in terms of priority, difficulty and duration; (b) define the tasks’ targets; (c) and face unexpected problems during the realization of these tasks. Moreover, schizophrenia is characterized by a great heterogeneity in regard to their everyday life difficulties and cognitive functioning. At present, patients’ multitasking capacities have not been adequately examined in the literature due to an absence of suitable assessment strategies. We thus recently developed a computerized real-life activity task designed to take into account the complex and multitasking nature of certain everyday life activities where participants are required to prepare a room for a meeting (i.e. the Computerized Meeting Preparation Task, CMPT). The aim of this study was to examine the multitasking abilities in persons diagnosed with schizophrenia and in particular the existence of subgroups of patients in regard to their performances on cognitive measures and on the CMPT. Sixty-two patients diagnosed with schizophrenia and 39 paired healthy controls completed the CMPT and a cognitive battery. The results reveal that the CMPT possesses good sensitivity and suggest three underlying constructs of multitasking (Memory, Planning and Intent), which were found to be underpinned by several cognitive functions and multitasking aspects. Moreover, cluster analyses revealed subgroups of patients differing in terms of their cognitive and CMPT performances. Taken together, these results show the need for a cognitive model of multitasking abilities in persons diagnosed with schiozphrenia. Taken together, this cognitive model and the CMPT, could be a good basis for cognitive interventions of multitasking abilities in schizophrenia. Finally, the results underline the heterogeneity of schizophrenia. [less ▲]
