« L’enseignement de base est obligatoire pour tous les enfants de six ans à seize ans », ainsi stipule l’article 4 de la Loi d’Orientation de l’Éducation au Burkina Faso. Dans cette communication, nous partirons d’une expérience d’offre et de demande scolaire dans une zone rurale du centre-est du Burkina Faso. Nous verrons comment l’école, de par son fonctionnement interne et sa structuration, a transformé l’engouement en désaffection. Cette expérience rurale n’est pas isolée. Elle nous permet ensuite d’interroger le système scolaire burkinabè contemporain : ses curricula, son fonctionnement interne, sa sélection et sa finalité. Enfin, nous examinerons dans quelle mesure cette école-là peut être une alternative au “travail des enfants”, dont l’élimination semble être une priorité politique depuis une quinzaine d’années. La présente communication s’inspire d’une recherche doctorale en cours. [less ▲]

One major drawback of the post-combustion CO2 capture using conventional amine solvents is solvent degradation, which can be due to thermal as well as oxidative mechanisms. Degradation affects the CO2 capture process since it may cause corrosion, foaming and fouling, possibly inducing a decrease of the solvent efficiency and high additional operating costs due to solvent replacement. In order to study degradation of conventional amine solvents as well as degradation of novel solvents, a degradation test rig has been built at the University of Liège in collaboration with the company Laborelec, member of the GDF SUEZ group. Since degradation generally occurs within a few months in real plant conditions, this equipment has been designed to allow the study of different degradation mechanisms under accelerated conditions, at high temperatures (up to 140°C) and high partial pressures in oxygen and CO2 (total pressure up to 20 bar with varying gas composition). An advantage of this degradation test rig is that it can be used in batch as well as in semi-batch mode with constant gas flow. High gas-liquid contact efficiency is also ensured thanks to a mechanical agitation system combined with gas bubbling. For a typical run, 300g of aqueous amine solution (30 wt % MEA in water) is introduced into the reactor and degraded during two weeks. The degraded solutions are then analysed using high pressure liquid chromatography (HPLC) for MEA quantification and gas chromatography with flame ionization detector (GC-FID) for the characterization of degradation products. The gas phase is analysed by Fourier Transform Infra Red spectroscopy. The final objective of this work is to implement the data obtained from experimental results on the degradation test rig into an existing simulation model that has been developed based on an existing pilot plant.

Avec les avenues qu’offre le Web2.0, le processus d’évaluation des apprentissages en éducation/formation pourrait subir des transformations auxquelles on n’osait penser il y a très peu de temps. Il est ainsi fort possible que la contribution humaine à ce processus soit toute autre que celle que les étudiants du XXe siècle ont connue. Mais ces transformations à venir du processus d’évaluation et de ses objets signifient-elles qu’il y aura un prix à payer en termes de validité et de fidélité ? Ainsi, l’entrée en jeu de nouveaux outils pour observer et recueillir des données sur les compétences développées pose des défis particuliers parce que dans une approche par compétence ce qui doit être évalué diffère passablement de ce qui est valorisé lorsque les seules connaissances sont visées. L’effervescence observée à cet égard est ainsi une bonne occasion pour faire le point sur ce qu’il est possible de faire pour évaluer des compétences en utilisant l’ordinateur (i.e. les TIC) et sur la validité et la fidélité du processus d’évaluation dans ce contexte.

Clownfishes are brightly coloured coral reef fishes well known for their mutualistic symbiosis with tropical sea anemones. These fishes live in social groups in which there is a size-based dominance hierarchy. In this structure where sex is socially controlled, agonistic interactions are numerous and serve to maintain size differences between individuals adjacent in rank. Clownfishes are also prolific callers whose sounds seem to play an important role in the social hierarchy. Agonistic interactions being involved in daily behaviour suggest how important acoustic communication might be in their way of life. Recording the different acoustic behaviours indicated that sounds are divided into two main categories: aggressive sounds produced in conjunction with threat postures (charge and chase), and submissive sounds always emitted when fish exhibited an appeasement display (namely the head shaking movements). Both types of sounds showed size-related intraspecific variation in dominant frequency and pulse duration: smaller individuals produce higher frequency and shorter duration pulses than larger ones. Consequently, these sonic features might be useful cues for individual recognition within the group. On the other hand, no acoustic call was associated with courtship and reproductive behaviours. Unlike other pomacentrids, sounds are not produced for mate attraction in clownfishes but to reach and to defend their breeding status, which explains why constraints are not important enough for promoting call diversification in this genus. However, acoustic signals seem to be an integral part of the peculiar way of life of clownfishes, although they are restricted to agonistic interactions only. [less ▲]

We report on the extraction of dihadron fragmentation functions (DiFF) from the semi- inclusive production of two hadron pairs in back-to-back jets in e+e− annihilation. A nonzero asymmetry in the correlation of azimuthal orientations of opposite π+π− pairs is related to the transverse polarization of fragmenting quarks through a significant polarized DiFF. A combined analysis of this asymmetry and the spin asymmetry in the SIDIS process ep↑ → e′(π+π−)X has led to the first extraction of the u and d-flavor transversity parton distribution function in the framework of collinear factorization.

Cette communication présentera les résultats d’une enquête quantitative sur les représentations sociales des handicaps menée en Belgique Francophone en 2010. Selon Moscovici, Il existe un lien fort entre représentations sociales et attitudes. Les représentations sociales préparent à l’action et guident les comportements. Les comportements et les attitudes peuvent, à leurs tours, déforcer ou renforcer les représentations. Notre recherche a permis d’approcher les représentations sociales des handicaps en sondant les attitudes, les comportements et les opinions en Belgique francophone. Trois dimensions ont été suivies : les sentiments et attitudes envers le handicap en étudiant la peur, la compassion et le sentiment d’inconfort ; la place personne handicapée en utilisant des cercles concentriques autours du répondant et enfin la citoyenneté et les droits des personnes en situation de handicap. L’originalité de cette recherche réside dans l’analyse comparative entre des opinions et des attitudes envers différents types de handicap. Nous avons mis au point un procédé permettant de comparer les attitudes envers trois handicaps types: le handicap moteur, le handicap mental léger et le handicap sensoriel, afin de tester les différences de représentations envers ces objets dans le but de faire émerger les représentations sociales envers des handicaps précisés.

Background: The most widely used mice model of chronic graft-versus-host disease (cGvHD) is an MHC-matched bone marrow transplantation model of sclerodermatous cGvHD. A limitation of that model is that mortality is relatively low, making difficult to study the impact of potentially therapeutic compounds. Aims: To develop a more severe model of cGVHD and to assess the impact of Rapamycin administration in that model. Results: Lethally irradiated Balb/C mice were injected with 10x106 bone marrow cells and 70x106 splenocytes from B10.D2 donor mice. Twenty-one days later, all mice developed cGvHD. For the severe model, donor B10.D2 mice were injected with 0.5x106 splenocytes from Balb/C twenty-one days before transplantation. All mice from the severe model (n=8) died a median of 32 days while 3 of 7 mice in the classical model survived beyond day 52. Mean survival was decreased in the severe model compared to the classical model (32 days versus 37 days; p=0.0185). Recipient mice in the severe group experienced higher weight loss, hair loss and skin fi brosis. Numbers of T lymphocytes (231.9 ± 151.4 versus 951 ± 532.8; p=0.0032) and CD4+ T cells (63.25 ± 41.93 versus 135.0 ± 14.39; p=0.0018) per microliter of blood at day 21 were lower in the severe group than in the classical model. Moreover, number of regulatory T cells (Tregs) was decreased in the severe model (1.250 ± 0.8864 versus 8.000 ± 6.753; p=0.0151). We then investigated whether rapamycin administration could prevent GVHD in the severe model. All (n=8) mice treated with PBS (placebo) died a median of 32 days after transplantation, while 6 of 8 mice given 1 mg/kg/day i.p. rapamycin survived beyond day 52 (p=0.0012). Number of Tregs/μl was higher at day 21 in rapamycin-treated mice than in mice given PBS (2.000±1.195 versus 1.250±0.8864; p=0.0796). Moreover, number of naïve CD4+T (10.00±4.192 versus 30.25±5.185; p= 0.0089) and effector memory T cells (EMT) (30.67±3.180 versus 67.33±7.881; p= 0.0125) were higher in rapamycin mice. Finally, proliferation of EMT (assessed by fl ow cytometry using Ki-67) was higher in PBS than in rapamycin mice (45.28%±4.084 versus 31.90%± 2.003; p=0.0474). Conclusion: We have developed a mice model of severe cGVHD. Interestingly, rapamycin prevented death from cGVHD in that model, perhaps through in vivo expansion of Treg. [less ▲]

1. Matériels et méthodes. Les difficultés mnésiques des patients à un stade léger d’une maladie d’Alzheimer sont marquées par une atteinte sévère de la récupération consciente des informations dans leur contexte d’apprentissage (recollection). Par contre, la reconnaissance des informations sur base d’un sentiment de familiarité (savoir qu’une information a été rencontrée auparavant sans récupérer son contexte d’apprentissage) est relativement préservée (Dalla Barba, 1997; Rauchs et al., 2007). L’objectif de cette étude était de révéler les substrats cérébraux des processus de recollection et familiarité dans la maladie d’Alzheimer au moyen d’une tâche de mémoire associative analysée selon les principes de la Procédure de Dissociation des Processus (Jacoby, 1991). Pendant une acquisition en IRM fonctionnelle, 26 patients avec une maladie d’Alzheimer probable à un stade léger et 17 témoins âgés ont étudié des paires de mots, puis ont dû les reconnaître parmi des paires recombinées (deux mots vus mais pas ensemble) et des paires nouvelles. 2. Résultats. Les analyses comportementales ont indiqué que 10 patients Alzheimer avaient des indices de recollection nuls (AD-), tandis que 16 autres patients présentaient des processus de recollection résiduels (AD+) bien que significativement moins importants que les témoins. Par contre, le score estimant la contribution des processus de familiarité était équivalent dans les trois groupes. L’analyse de l’activité cérébrale a montré que, chez les patients AD+ comme chez les témoins, la recollection activait le cortex cingulaire postérieur. Cependant, cette région était fonctionnellement connectée à l’hippocampe, au cortex pariétal inférieur et au cortex préfrontal dorsolatéral uniquement chez les témoins. Par ailleurs, dans les trois groupes, la familiarité activait le sillon intrapariétal. 3. Conclusion. Cette étude montre un déficit sévère de recollection et une relative préservation de la familiarité chez des patients Alzheimer. Lorsque les patients possèdent des capacités résiduelles de recollection, celles-ci sont soutenues par le cortex cingulaire postérieur comme chez les personnes âgées saines. Cependant, une perturbation de la connectivité fonctionnelle entre le cortex cingulaire postérieur et des régions impliquées dans la mémoire relationnelle, les aspects subjectifs de la recollection et les processus de monitoring post-récupération suggère que la qualité de la recollection résiduelle des patients Alzheimer est dégradée. 4.

En Belgique, et plus précisément en Wallonie, la Cellule de reconversion est le dispositif privilégié depuis 1977 par les pouvoirs publics afin de prendre en charge les travailleurs victimes d’un licenciement collectif et de leur permettre de retrouver un emploi. Financé entièrement par la Région Wallonne, le dispositif est géré au jour le jour par des conseillers du service public de l’emploi wallon, le Forem, en partenariat avec un ou plusieurs « accompagnateurs sociaux », anciens délégués syndicaux issus de l’entreprise en restructuration et comptant parmi les victimes du licenciement collectif. Le dispositif est mis en place pour une période d’un an. Durant cette période, il accompagne les travailleurs licenciés au rythme d’activités collectives et individuelles, de formations courtes ou longues, afin de permettre à ces travailleurs de retrouver un emploi, dit « de qualité ». La cellule a pour vocation d’être le guichet unique à disposition de ses bénéficiaires afin que ceux-ci y remplissent leurs obligations administratives en tant que demandeurs d’emploi, s’inscrivent à une ou plusieurs formations assurées par des prestataires privés ou publics, répondent à une offre d’emploi, etc. En ce sens, la cellule joue un rôle d’interface entre le collectif de travailleurs licenciés et le marché de l’emploi. Cet article s’inscrit dans le cadre du projet « En-Train » financé par l’Agence Belge du Fonds Social Européen et dont l’objectif est d’accompagner le développement et la formalisation des cellules de reconversion. Une des activités de ce projet portant sur l’analyse qualitative et quantitative de ces cellules, nous proposons de présenter ici les premiers résultats du suivi d’une cellule lancée en région liégeoise au printemps dernier. Il s’agira non seulement d’analyser les résultats de ce dispositif, en se posant la question du taux de retour en emploi après dix mois de fonctionnement de la cellule, mais également d’interroger les bénéficiaires de ces cellules sur la manière dont ils envisagent leur reconversion professionnelle.

Our study helps understand how fragmented forests affect bonobos forest use. Previous studies already reveal that habitat types influence bonobos’ densities, but forests’ spatial structure could also have an impact. In the current context of deforestation and increasing illegal concessions, approaching such questions should help orient future conservation programs. We focus on the influence of edge effect on bonobos forest use, presuming that they avoid areas with non mature forests and increased human pressure. We travelled along transects (113km total) to define habitat types and to record bonobos indices (tracks, food remains and nesting sites) in 200km² of forests in Southwestern Lake Tumba Region. Our results show that bonobos clearly prefer specific habitats for nesting, and, within these nest-forest types, an understory of Marantaceae Haumania sp. is preferentially chosen. To evaluate edge effect on nesting behavior, we counted nesting sites in 100m distance classes from the forest edge. Our results indicate a uniform distribution of nesting sites, but with a negative edge effect in the first 100m. When we analyzed tracks and food remains distribution, we didn’t find any habitat type preferences or any edge effect. These results indicate that, although bonobos are known to favor dense forests, they can also adapt to fragmented forests environment. Habitat types appear to be more relevant to understand their distribution and range. [less ▲]

The magnetosphere is known to respond to solar wind driving by displaying a variety of behaviours known as magnetospheric modes, including the substorm cycle, sawtooth intervals, and steady magnetospheric convection. Other behaviour includes geomagnetic storms and periods of relative magnetospheric quiescence associated with northward interplanetary magnetic field. There have been many studies of the changes in magnetospheric open flux content during different modes to investigate the role of magnetic reconnection at the magnetopause and in the magnetotail in determining the magnetospheric response. In this study we attempt an automated recognition of different modes by their characteristic signatures in geomagnetic indices and other magnetospheric state parameters, including open flux. This allows us to investigate the interplanetary conditions that give rise to different behaviours. [less ▲]

Dairy milk production in Moc Chau contributes to improve the welfare of farm households. It generates daily income for farmers, provides a highly nutritious food for people, create employment opportunities for the society. Although it brings a rather high income for farmers, their lives are very hard, and their living standard is quite low. This study aims to apply a monitoring system in farms to assist farmers improving their performance. Six field trips were carried out to help dairy farmers to monitor their farms and collect economic and technical data in 2010-2012 in Moc Chau. The main findings are: stocking rate, milk yield and income were rather high but varied largely from this farm to others. Cost control in farm was not good thus dairy margin was not high. Purchased feed cost was too high. Homegrown feed accounted for a small part of cost but produced large amount of milk while purchased feed dominated a very large proportion of cost but produced less milk quantity. Most of the farmers followed the objective of increasing milk production but did not pay attention to the quality of herd and milk; did not make an optimal decision. Experience, land area, and herd size were the major factors that increased economic performance in farms. [less ▲]

From Engels to Adorno and Horkheimer, to Althusser or Bourdieu everything seems to occur as if criticism in its main variation – the Marxist approach – had worked to feed a principal way of thinking: individuals (workers, proletarians, social actors, etc.) unconsciously reproduce the social structures of capitalism which alienate them. They accept the conditions enforced on them and no longer seek to rebel against a world which substantially impoverish their labor, their soul and their creativity. Even worse: they ensure the reproduction of the system by seeking to engage in mass consumption at any price. There is little doubt that Marx was not wrong to point out, with the concept of alienation, the inhuman working conditions in which the nineteenth century proletariat was, and which a huge part of the workers still have to face all around the world nowadays. Should the worker-consumer only be seen as a scatterbrain being who unconsciously reproduces, to use Bourdieu’s language, the conditions of his domination? My intention here is not to put Marx in the dock, since he is, I am sure, an author whose work has remained of unequalled power for over a century. However, I would like to try and show that by dint of favouring almost exclusively the concept of alienation in his work, there is a considerable risk that only a negative path for criticism can emerge from it. It is that initial heart of criticism which was Marx’s thinking and which has irrigated the whole twentieth century from the Frankfurt School to French critical sociology that I would like to put into perspective by suggesting a new agenda for critical research that I would characterize as, for now and for lack of a better term, positive. This agenda of research is in its early days. Nonetheless, in my opinion, a theoretical base should be given to it straight away. The following pages will try to establish it by notably drawing on the main theoretician of libertarian anarchism, Marx’s rival on socialist theory, Proudhon. However, I would like to insist on the fact that the purpose is not to truly turn the latter against Marx . Because I think that Marx must remain a topical issue, I rather wish to demonstrate that, at the cradle of criticism, right next to him, there is an equally – or even more? – Materialist position which could be pertinently combined to the criticism of alienation . This position might be helpful to highlight, here and now, possibilities of emancipation through labor which are not exclusively conditioned by the “Grand Soir”. Proudhon’s work is certainly philosophically and economically weaker than Marx’s. However, Proudhon is very interesting in the way he manages to see in a “laboring” man something else than a slave-laboring animal deprived of subjectivity by capitalism and who only exists as a production tool. In that way, criticism, if any, may be considered as positive [less ▲]

Over the last decade, China has deeply affected the economic map of Latin America. Many of regional countries quickly increased their exchanges with China and got engaged in new partnerships, while questioning the American leadership. Numbers of researches tend to analyse the Sino-Latin American relationship with the eyes of reciprocity. This contribution rather makes the choice of analysing China’s strategy for growth on the world stage, focusing onto Latin America. By integrating all dimensions of the Chinese power through its foreign policy and its incantatory diplomacy, this article will identify real Chinese influence by measuring the distance between perception (cooperation) and reality (hegemony).

It has been suggested that mathematics learning disabilities, including those of genetic origin, result from a basic impairment of quantitative representations. In Williams syndrome in particular, recent studies report a specific deficit in tasks requiring symbolic and non symbolic numerical magnitude processing (Krajcsi et al., 2009 ; O’Hearn & Landau, 2007; Paterson et al., 2006). However, to our knowledge, the integrity of non numerical quantitative processing has never been investigated. Moreover, in the visual modality, it is difficult to disentangle the influence of the massive visuo-spatial impairment, which is a main characteristic of the cognitive phenotype of Williams syndrome, from the numerical magnitude processing deficit. Therefore, numerical and non numerical acuity were assessed in a group of patients with Williams syndrome using tasks with different visuo-spatial processing requirements. To assess the processing of non numerical continuous quantities, participants were asked to compare the length of two sticks (spatial dimension) vs. the duration of two sounds (temporal dimension). Their ability to process non-symbolic numerical magnitudes was explored in tasks requiring the comparison of two arrays of elements (spatial arrangement) versus two sequences of dots flashed in a single location (no spatial processing). Finally, their access to symbolic number meaning was assessed through the numerical comparison of two Arabic numbers vs two Spoken verbal numerals. In each task, the ratio between the quantities was manipulated in order to measure the entire psychophysic curve and to measure the acuity of their numerical and non numerical magnitude representations in non-symbolic tasks.
