Several studies explored the relationship between verbal short-term memory (STM) and numerical cognition, but with inconclusive findings. The present study re-explored this relationship, by adopting the critical distinction between STM for item information (the items to be retained) and STM for order information (the order of the items within a list). We hypothesized that especially STM for order should be related to the development of numerical abilities, given that recent studies suggest the intervention of common processes during the representation of order information in STM and numerical tasks. We investigated item and order STM abilities and numerical processing abilities in 72 children during their third year in kindergarten. We observed that order STM abilities, but not item STM abilities, correlated significantly with performance on numerical order judgment and calculation tasks. These associations remained after control of interindividual differences in verbal and non-verbal cognitive efficiency. Our results suggest a specific relationship between order STM processes and numerical cognition, opening new perspectives for our understanding of the STM determinants of numerical cognition development.

A monitoring of Giardia lamblia and Cryptosporidium parvum occurrence was conducted for 2 years in the largest drinking water reservoir of Luxembourg (Esch-sur-Sûre reservoir) using microscopy and qPCR techniques. Parasite analyses were performed on water samples collected from three sites: site A located at the inlet of the reservoir, site B located 18 km downstream site A, at the inlet of the drinking water treatment plant near the dam of the reservoir and site C where the finished drinking water is injected in the distribution network. The communication presented the main results of the survey and the assessment of risk infection with parasites. [less ▲]

Aphids are some of the most serious pests of cultivated crops worldwide, causing major yield and economic losses. Previous works have demonstrated ants and natural enemies (including ladybeetles and hoverflies) to be able to use aphid volatile chemicals to locate aphid colonies. Here, we report the first isolation of a bacterium from the pea aphid Acyrthosiphon pisum honeydew, Staphylococcus sciuri, which produces kairomones used by the aphidophagous hoverfly Episyrphus balteatus and the Asian Ladybeetle Harmonia axyridis during their search for prey colonies. Some specific semiochemicals produced by S. sciuri were identified as attractants and ovipositional stimulants. Similarly, we have shown scouts of the aphid tending ant species, Lasius niger, to orientate their foraging behaviour toward an Aphis fabae infested plant and we have demonstrated that the odours released by this aphid honeydew were attractive for ant scouts. Again, bacteria were involved in the production of these honeydew semiochemicals. Interestingly, ant scouts were also able to discriminate honeydew odour from A. fabae (usually attended by L. niger) and A. pisum (unattendedby L. niger). Comparison of the volatile and bacteria composition of both aphid species honeydew were attended. [less ▲]

Studies on nationalism were often interested with the city, especially the city centers. The politics of heritage, the architecture of public buildings and the design and use of central public spaces are often studied in relation to national identity politics. Municipal politics of the historical city in the face of central authorities’ urban politics is also frequently approached in the light of Nation-State building issues. If no doubt the consideration of city centers as a vantage point for understanding the relation between nationalism and the city is an interesting one that bore many fruits, we believe that a vantage point concentrating on the peripheries can highly contribute in unveiling other aspects of this relation. This paper aims at investigating the potentialities of this contribution. As the place where urbanization is taking place, the periphery is: - Where the national identity construction logic is put to test. First because, historically, it is here where the confrontation between the urban and the rural did first take place. Second, because rural exodus and migration, usually more important in the periphery, will continue to challenge it. - Where the city and the hinterland get connected through different national territory building networks. - Where the Nation-State central authorities will find the largest land reserves to develop their large emblematic projects. - Where urban fragmentation poses the strongest challenge to the unitarian message of nationalism, but also is where some nationalist movements might best develop In fact, the periphery represents equally a fertile ground for nationalism and for resistances to it. This paper will rely on the city of Beirut as a case study. [less ▲]

Mg-Al-Zn alloys have been reinforced with carbon fibres using friction stir processing (FSP) which appears as a promising alternative for the large-scale production of C-Mg composites. The process has shown its ability to produce sound composites with enhanced strength compared to the non-reinforced alloys. The C fabric is fragmented in short fibres leading to a reduction in grain size and an improved hardness. [less ▲]

Hotelling’s T2 control chart is one of the most popular multivariate control charts for monitoring multiple variables simultaneously. Recent studies have shown that applying the T2 control chart by using a variable parameters (VP) scheme yields more rapid detection of assignable causes than the classical method of taking fixed sample sizes at fixed intervals of time. This paper presents an economic-statistical design (ESD) of the VP T2 control chart using the general model of Lorenzen and Vance. The genetic algorithm (GA) is then employed to search for the optimal values of the eight test parameters of the chart. Furthermore, VP and FRS schemes are compared with respect to the expect cost per unit time. [less ▲]

In Belgium, as in many other countries, relatively anarchic economical and industrial development of the past century has resulted in a significant number of contaminated sites. When one of these sites poses a risk to human or ecosystem, measures need to be taken to clean it up. Among these measures, methods using in situ bioremediation are beginning to become more important because of their ease of implementation and their relatively low cost. However, it is often difficult to ensure their effectiveness except by carrying out extensive drilling and sampling, which can be long and expensive while offering only punctual information. Thus, it becomes necessary to use other techniques to overcome these shortcomings. Recently, an increasing interest is being born to use geophysical methods as tools for remediation monitoring. As part of our work, we conducted several electrical resistivity tomography campaigns on a bus station located in Bassenge (Belgium) which has undergone a contamination of hydrocarbons (gasoline) for several years and on which a biostimulation remediation device was set up in order to clean it up. The aim of our investigations was to study the electrical response of the contaminated area during the remediation phase and whether electrical resistivity tomography allowed to monitor its effectiveness. After a year of monitoring, the time lapse images obtained show a significant decrease of electrical resistivities (up to -40%) during biostimulation at the location of the main contaminant plume and an increase again of resistivities from the time the biostimulation was stopped. The electrical response during the biostimulation is in agreement with the models presented by several authors in the literature. The increase again of resistivities after the stimulation is however more surprising and can be explained by several physico-chemical (sorption-desorption processes) or biological (decrease of conductive biofilms) assumptions. The results obtained tend to suggest that it is possible to use electrical resistivity tomography as a tool for qualitative control during the remediation of a contaminated site. However, for a more quantitative use of resistivity models, it is important to assess their reliability through the use of resolution indicators. We therefore developed a methodology to address this issue based on the creation of synthetic models representing simplified cases of field resistivities and we applied it on our case study. The results obtained provided us important information about the reliable parts of the resistivity models. These findings may lead in the future to the development of mathematical models that can link quantitatively geophysical properties to the level of (de)contamination of a site. [less ▲]

De plus en plus de dispositifs d’évaluation (évaluation formative, monitoring, épreuves d’orientation scolaire, …) ont recours aux Modèles de Réponse à l’Item pour estimer les compétences scolaires des élèves au départ de tests papier-crayon ou d’épreuves proposées sur ordinateur. Ces modèles de mesure – dont les propriétés laissaient entrevoir des progrès et des avantages considérables – se sont d’abord imposés comme standards de référence dans les enquêtes internationales pour être ensuite transposés dans des contextes locaux, notamment pour l’évaluation externe des compétences des élèves. Cependant, la technicité des MRI, leur nature stochastique et leurs composantes statistiques relativement complexes n’ont pas toujours permis une approche cartésienne et prudente de leur exploitation. On a cru pendant longtemps que la transposition de ces modèles à l’évaluation des compétences était naturelle et ne souffrait d’aucun obstacle fondamental. Mais les objectifs, les caractéristiques et les exigences de l’évaluation des compétences sont parfois bien éloignés des préoccupations internationales. Nous nous proposons donc, au départ des résultats empiriques et/ou des réflexions théoriques des intervenants de la table ronde, de déterminer dans quelles conditions l’application des MRI à l’évaluation des compétences est pertinente? Dans cette perspective, plusieurs critères d’analyse seront envisagés : la nature théorique des modèles (les MRI sont-ils adaptés pour atteindre les objectifs des dispositifs d’évaluation des compétences?), les caractéristiques psychométriques des évaluations (les conditions d’application des MRI sont-elles toujours remplies dans le cadre des évaluations de compétences?) et les méthodes de validation des modèles (les méthodes pour évaluer l’adéquation des modèles sont-elles adaptées à l’évaluation des compétences?). Pour ne pas conclure, les intervenants s’interrogeront sur l’opportunité de développer de nouveaux modèles de mesure pour l’évaluation des compétences. Trois questions principales structureront les échanges : Question 1: Quelles sont les caractéristiques psychométriques des dispositifs d’évaluation des compétences ? Question 2: Les Modèles de Réponse à l’Item sont-ils adaptés pour évaluer les compétences ? Question 3: Est-il opportun de développer de nouveaux modèles pour l’évaluation des compétences ? Si oui, quelles devraient en être les caractéristiques ? [less ▲]

« 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 ▲]

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.

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.

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 ▲]

In vivo T cell depletion of the graft with anti-thymocyte globulin (ATG) or with alemtuzumab has been frequently used in the setting of RIC allo-SCT from unrelated donors. This survey compared allo-SCT outcomes between 364 AML patients in first CR given unrelated PBSC after chemotherapy-based RIC and given either ATG (n=213) or alemtuzumab (n=151) in the conditioning regimen. Alemtuzumab patients were more frequently given grafts from HLA-mismatched donors (30% versus 16% having at least 1/10 HLA-mismatch with their donor, P=0.005), and were conditioned more often with melphalan-based RIC (62%), while ATG recipients were more frequently conditioned with busulfan-based RIC (84%). Median time to neutrophil engraftment (>500 ANC) was 16 days in ATG recipients, versus 12 days in alemtuzumab recipients (P<0.001). The incidence of grade II-IV acute GVHD was 28% in ATG recipients (9 patients with grade IV) and 24% (NS) in alemtuzumab recipients (2 patients with grade IV). Two-year incidences of chronic GVHD, relapse and NRM were 45%, 23% and 14%, respectively, in ATG recipients, and 47% (NS), 25% (NS) and 25% (P=0.008), respectively, in alemtuzumab recipients. Two-year OS and LFS were 69% and 63%, respectively, in ATG recipients, versus 55% (P=0.003) and 51% (P=0.02), respectively, in alemtuzumab recipients. Death from infection occurred in 7% of ATG recipients, versus 12% of alemtuzumab recipients. When the analysis was restricted to the 210 patients given grafts from 10/10 HLA-matched unrelated donors, the use of alemtuzumab (n=64) remained signifi cantly associated with higher NRM (22% vs 9%, P=0.007), lower LFS (58% vs 69%, P=0.07), and lower OS (62% vs 74%, P=0.04). In multivariate analyses (performed in patients given grafts from 10/10 HLA-matched donors), in comparison to the use of ATG, the use of alemtuzumab was associated with higher NRM (HR=2.5, P=0.025), a statistically non-signifi cant but higher relapse rate (HR=1.7, P=0.18), and signifi cantly worse LFS (HR=0.5, P=0.013) and OS (HR=0.4, P=0.002). In summary, this homogeneous cohort of AML patients transplanted in fi rst CR and given PBSC grafts from unrelated donors, the use of alemtuzumab in comparison with ATG was associated with worse LFS and OS.

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.

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.

This paper aims at proposing an integrated model of the performance management of SME's of the luxury industry through the organization of key success factors (KSF) identified in a critical sample of the existing literature. The model is constructed on a basis of the Porter's value chain (1998) and the resource-based theory (Wernefelt, 1984; Berney, 1991) that helps to identify the critical resources and their deployment through the SME's value chain that lead to manage the identified KSF.

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 ▲]

The analysis of cases of several Belgian juvenile courts (Antwerp, Brussels, Namur, Arlon) revealed questionable practices within some establishments for young delinquents. One institution in particular (Refuge Sainte Madeleine, Brussels), specialized in the rehabilitation of delinquent (and often pregnant) girls, developed suspicious methods of treatment. Indications of dysfunction in this private institution are numerous, and present a lot of similarities with practices observed in Irish Magdalene Asylums: teenage girls employed in a laundry run by a religious congregation, unexplained « disappearances » of the children born to delinquent girls, very high death rates, complaints from minors themselves and from their families regarding forms of negligence and even abuse. This local example leads us to question the practices of the Belgian protection system, and more specifically, the ‘pedogical approach’ in Magdalena covents. How to describe and explain the ‘pedagogical approach’ implemented within these institutions? What is the daily life of the institutionalized girls taking into account their living conditions and implemented discipline? Who worked in these private institutions? Were they trained in modern techniques of rehabilitation, and if so, what principles and applications were associated with these techniques? What is the influence of the Belgian separation between public and private sector with the child protection system? This case also invites us to examine the tension between official discourse and practice and raises questions on gendered reactions within the Belgian system. [less ▲]

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 ▲]
