The Building Construction System « Upbrella » proposes a new concept for the erection of high-rise buildings and offers a controlled and isolated work environment by integrating a protective mobile roof and wall during construction. Therefore lower floors could be occupied once their construction is completed, while other higher floors are still under construction.We aim to explore, using a design science approach, how the overall construction phase could be optimized the by integrating some of BIM and LEAN construction processes within the Upbrella system. A first six-story building will be erected from June 2012 in order to test the system. The building will be built in two phases (3 floors per phase). The first phase will consist of a traditional construction without the Upbrella system and the second phase will use the Upbrella system. [less ▲]

Le Service de Surveillance et de Renseignements aux Frontières (S.S.R.F.) est un service de surveillance mis en place en théorie sur l’ensemble du périmètre frontalier belge. Il se compose de gendarmes, auxquels sont adjoints dans un premier temps des douaniers et des agents des Eaux et Forêts. Le S.S.R.F. connut deux périodes d’existence officielle. La première s’étend de 1896, année de parution de la première ordonnance régissant le service, à l’invasion allemande. La seconde correspond à la réapparition du projet dans les années 1930 qui devait aboutir au fonctionnement du service pendant toute la « drôle de guerre » jusqu’à la campagne de mai 1940. La première période, où le S.S.R.F. fonctionne quelques jours seulement, de la toute fin du mois de juillet 1914 à l’invasion allemande, ayant fait l’objet d’une précédente publication , l’exposé sera consacré à la période postérieure à la Première Guerre mondiale. En effet, un projet théorique de remise sur pied du S.S.R.F. reprend vigueur dans les années 1930. Relativement mieux préparé et organisé dès le temps de paix (retrait des douaniers du service, meilleure coordination avec le réseau de surveillance de l’armée), il fonctionne plusieurs mois durant à partir de la mobilisation de l’armée belge en septembre 1939. Dans le contexte de la « neutralité choisie », le périmètre sur lequel le S.S.R.F. est effectivement en place est considérablement étendu : frontière française, allemande, luxembourgeoise, moins rigoureusement la frontière des Pays-Bas, sont concernées. L’objectif sera donc d’analyser le dispositif en place ainsi que les nuances en fonction de la frontière gardée. Cette communication est basée sur un mémoire de fin d’études défendu en janvier 2010 à l’Université de Liège en vue de l’obtention du grade de Master en Histoire. [less ▲]

Majority of operational sea surface temperature (SST) infra-red (IR) products have small overall bias but exhibit higher absolute biases in specific regions. Previous studies [for example Tomazic et al., 2011] showed that over Adriatic Sea there is a positive summer bias sometimes exceeding 0.5 K. Methodology to decrease regional biases [Le Borgne et al., 2011], based on using atmospheric profiles, surface SST fields and radiative transfer model to simulate the non-linear split window SST (NLSST) algorithm error, was used to assess the impact of atmospheric profiles with different spatial resolution (ECMWF: 0.125 deg and ALADIN 2 km), different input surface SST fields (OSTIA 6 km and CNR UHR L4 1 km) and different time and space averaging criteria’s in deriving the algorithm correction. SST corrections derived for the NLSST Spinning Enhanced Visible and Infrared Imager (SEVIRI) algorithm for five months (July, October and December 2010 and March and July 2011) are validated with AATSR L2 SST fields and compared to already implemented regional correction procedure at Center de Meteorologie Spatiale (CMS) to assess the optimal combination of space and time averaging criteria’s and input fields. Results show that the best improvement for all available months and for both day and night is obtained when using spatial averaging over the whole domain in combination with time averaging between the last 15 and last 31 days both for day and night time analysis. Using higher resolution ALADIN atmospheric profiles with OSTIA input SST fields didn’t improve the SST correction compared to using combination of coarser ECMWF atmospheric profiles and OSTIA input SST. Small improvement, based only on analysis for two months in 2011, is obtained when using both higher spatial resolution atmospheric profiles (ALADIN) and higher resolution input SST fields (CNR UHR L4 1 km). The best improvement obtained for spatial averaging over the whole domain (Adriatic Sea) suggests that the domain should be more extended (to Mediterranean Sea) to derive optimal spatial averaging, while conclusion of improvement obtained when using both the higher spatial resolution atmospheric profiles and input SST field need extension of analysis on other months in 2010.

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 ▲]

BACKGROUND. Overweight and obesity in youth must be combated through a multiple approach combining management principles in nutrition and physical activity (PA). In the hospital context, medical staff seems to be more focused on nutrition. AIM. In this study, we proposed to implement a specific intervention focusing on PA in parallel with traditional paediatric and dietetic visits designed to 6-12 year-old children. METHODS. Data were collected in three steps: (1) after a visit at the hospital, subjects and their parents answered to a questionnaire (lifestyle, representation about PA) and attended to a meeting during which they received written (illustrated booklet) and oral cues about PA as well as an invitation to use a PA diary and a pedometer; (2) before the next visit (almost 8 weeks interval), they were free to apply the recommendations; (3) after the next visit to the hospital, subjects analyzed the diary with one of the researchers and answered to questions about their current lifestyle and representations about PA. 34 children respected the whole protocol. FINDINGS. Among the children and their parents, representations of PA changed between the visits (PA was no longer regarded merely as sport). Major changes were also identified in children’s lifestyle (increase of number of weekly PA, family PA, weekly PA time; decrease of inactivity time like TV or video games). Only 27 children out of 34 used the PA diary at least once (information were recorded for a mean of 18 days/child between the 2 visits – a third of the duration of the interval). The pedometer has been used by 15 children and was considered as a motivating tool. 58.5% of comments collected at the end of the second meeting were positive and emphasized the interest of the intervention; 24.6% were negative and mainly focused the PA diary). DISCUSSION. This study underlines the need to improve the family's representations about PA in paediatric and dietetic visits. It supports PA experts' integration in the staff. [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.

Au Bénin, la production cotonnière s’est accompagnée d’une surexploitation des ressources foncières et a entraîné à long terme leur dégradation. Ainsi, diverses initiatives se développent pour une gestion rationnelle de la fertilité du sol avec un regain d’intérêt pour la fertilisation organique. A partir d’une typologie des cotonculteurs du Nord-Bénin établie suivant des critères endogènes de prospérité, cet article révèle l’existence d’une diversité de pratiques paysannes de gestion de la fumure organique. Ainsi, le niveau de prospérité détermine dans une certaine mesure les stratégies de gestion adoptées par l’exploitant, stratégies basées sur une maximisation des apports de matière organique plutôt que sur les exigences agronomiques du cotonnier. L’étude a montré la nécessité de mener des recherches pour mieux apprécier l’efficacité de telles pratiques et leur impact dans la restauration de la fertilité des sols. [less ▲]

The transcription factors of the soxE family, including sox8, sox9 and sox10 play important roles in diverse developmental processes. However little is known about their function during inner ear development. In the developing inner ear we detected sox9 and sox10 in the sensory epithelia since the formation of the otic placode. As the organ of Corti begins to differentiate, sox9 and sox10 expression are progressively restricted to supporting cells. To elucidate the role of sox10, we first analysed sox10 knockout mice. Using sox2 as a molecular marker of the prosensory domain, we showed that sox 10 is not required for its formation but is necessary for its maintenance. Indeed, we observed a significant shortening of the cochlear duct. Interestingly, expression of the notch ligand Jagged 1, which plays a crucial role during cochlear development, is decreased in the prosensory area of sox10-deficient mice. In parallel, using both gain- and loss-of function approaches, we showed that sox9 is required for cell patterning in the organ of Corti. Taken together, these results demonstrate diverse roles of soxE genes during the inner ear development, specification and maintenance of differentiated cells within the cochlea. [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 ▲]

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.

Dans l’état de Sao Paulo, au Brésil, de nombreuses cavités sont trouvées dans des grès continentaux du Jurassique affleurant dans le front de la cuesta d’Itaqueri. Ces grottes se développent subhorizontalement dans une lithologie compacte et non carbonatée. Elles peuvent s’enfoncer d’une centaine de mètres à dans le massif. Précédemment, plusieurs auteurs ont donné aux différentes failles parcourant les roches un rôle prépondérant dans la genèse des cavités. Deux hypothèses ont été proposées pour leur formation: une dissolution en profondeur, aux nœuds de fracturation et/ou une évacuation mécanique postérieure des résidus d’altération par des écoulements percolant à travers le massif et résurgeant dans le front de cuesta. Pourtant, plusieurs observations telles que l’absence de circulation d'eau à l’intérieur des grottes ou la dislocation de morphologies anciennes par les différentes fractures contredisent ces deux propositions. Les accidents répertoriés au sein des cavités sont datés de 126 Ma et viennent démanteler plus qu’accompagner le développement des systèmes souterrains préexistants. Ces failles permettent de déterminer une karstification initiale des grès antérieure, vraisemblablement en milieu noyé. [less ▲]
