In this paper, we present the results of three different studies of the Fomalhaut debris disk with infrared interferometry. First, VLTI/AMBER measurements are used to determine the position angle of the slightly oblate rapidly rotating photosphere by means of differential phase measurements across the Br-gamma photospheric line. This measurement allows us to confirm that the debris disk is located in the equatorial plane of its host star. Second, we use VLTI/VINCI to search for resolved near-infrared emission around the stellar photosphere, which would correspond to the presence of large amounts of hot dust grains located between the sublimation radius and the habitable zone. Our observations reveal a small excess of 0.88%+/-0.12% in K band relative to the photospheric flux. Finally, we use the Keck Interferometer Nuller in order to derive additional constraints on the nature of the resolved infrared emission. Our observations suggest a marginal detection of a circumstellar excess at 10 μm, which we use together with the VINCI detection to model the circumstellar emission. Preliminary results from this modeling effort are discussed. [less ▲]

Routine genetic evaluation for milk fatty acids is under development in the Walloon Region of Belgium. The objective of this study was to test the heterogeneity of residual variances and therefore indirectly the potential need to adjust for this heterogeneity if it exists. The residuals were computed as the difference between the observed and the estimated values using a multi-trait random regression test-day model, similar to the Walloon routine model, used for first lactation only milk yield, quantities and percentages of protein (PROT) and fat (FAT), content of saturated fatty acids in milk (g/100g of milk, SAT) and, content of mono-unsaturated fatty acids in milk (g/100g of milk, MONO). Residuals were considered homogeneous inside strata defined, among others, by weeks of lactation, by days in milk and by calendar months of test date. About 6,687,000 records were available for milk yield and for FAT and PROT parameters. For SAT and for MONO, about 184,000 records were available in this database. Means of residuals were stable and close to zero for all traits. Variances were more variable for MONO and SAT than for milk yield, for example. Daily and weekly variances tended to decrease at the end of the lactation (50%). When the variances were computed by month of test date, some variations were observed and some periods of year were more marked. In conclusion, the observed residual variances were less stable for MONO and SAT. We can conclude that introduction for heterogeneous residual variance is more important for the new traits (MONO, SAT) than it was for the old, traditional ones. [less ▲]

This document gives an overview of the challenges and issues related to a sustainable use of steel in the construction sector. After an introduction that concerns the challenges associated to the use of steel as a sustainable material, the principles of a life-cycle analysis are presented. The paper then focuses on the life-cycle inventory data of several products: finished cold-rolled coil, electro-galvanized steel, section rolling and rebar. The data are presented for two (sometimes three) different recycling rates. Indeed, since steel is recycled to more than 85% at the end of its life and recyclable and indefinite number of times, the presented inventory includes allocation for scrap inputs and outputs using the closed material loop recycling methodology developed by the International Iron and Steel Institute (IISI). A description of the method principles is also provided. The influence of the end-of-life credit method will be discussed. Corrosion and subsequently maintenance of steel products will be treated afterwards and a brief comparison of the life-cycle inventory will be provided for electro-galvanized steel and finished steel.

Differential item functioning (DIF) has received increasing focus in the past decades. Recently, Magis and De Boeck (2009) proposed to identify differentially functioning items as outliers in a one-dimensional space of DIF measures, using robust statistical tools for outlier identification. The purpose of this talk is to present an extension of this approach for the case of more than one focal group. In this multiple group framework, items can be characterized by multiple vectors of DIF measures, one for each focal group, so that a multivariate DIF space is obtained. DIF items can then be identified as outliers in this multivariate space, based on robust multivariate estimators of location and dispersion. The MCD (Minimum Covariance Determinant) estimator is shown to be adequate for this purpose. A major asset of the method that it can rely on existing DIF indices to define the DIF vectors, and that it does not need a purification step. Alternatively, it can be used to determine on an anchor set. The method will be illustrated by an example about calculator effects on mathematics test items. [less ▲]

The geometry of the scroll compressor determines the efficiency of the scroll compressor and controls all elements of its operation. It is therefore critical to be able to accurately model the volumes of the compressor over the course of a revolution. This paper proposes a novel quasi-analytic formulation of the suction, compression and discharge chambers based on a change of variables from involute angle to polar integration angle. This solution has been compared against a reference polygon solution, and for the suction chamber this solution agrees to within 0.02%. The solutions for the compression and discharge chamber volumes are analytic and incur a negligible penalty to overhead of a detailed compressor model. In addition, the general nature of the solution presented allows for multiple compression chambers and more complex discharge geometry. [less ▲]

Because of its resistance to corrosion and chemicals, relevant mechanical and esthetical properties, stainless steel (SS) is widely used in the daily life (food industry, household appliances, surgery …). However, SS is unable to prevent bacteria from adhering, proliferating and forming a resistant biofilm when ageing. Therefore, surface modification is needed for providing durable antibacterial properties. We report here on an all-in-one approach to prepare refillable antimicrobial films using the layer-by-layer deposition of polyelectrolytes. Specifically designed biocidal multilayered polyelectrolyte films that bear 3,4-dihydroxyphenylalanine (DOPA), known as a promoter of adhesion to inorganic surfaces, were deposited onto SS. DOPA was incorporated in the polycationic chains by radical copolymerisation of N-methacrylated DOPA with the quaternary ammonium salt of 2-(dimethylamino)ethyl methacrylate (DMAEMA+). In order to boost the antibacterial activity of the polycationic layer, AgNO3 was added to the aqueous solution of P(DOPA)-co-P(DMAEMA+), which resulted in the in-situ formation of silver based nanoparticles, sources of biocial Ag+. The layer-by-layer deposition of aqueous P(DOPA)-co-P(DMAEMA+)/AgCl/Ag0 suspension and aqueous solution of poly(styrene sulfonate) provides high antibacterial activity against Gram-negative E. Coli bacteria. Moreover, after silver depletion, films retain some antimicrobial activity, thanks to ammonium groups of the copolymer. We also show that the antibacterial activity of the films can then be easily re-boosted. [less ▲]

Logistic regression is a widely used tool designed to model the success probability of a Bernoulli random variable depending on some explanatory variables. A generalization of this bimodal model is the multinomial case where the dependent variable has more than two categories. When these categories are naturally ordered (e.g. in questionnaires where individuals are asked whether they strongly disagree, disagree, are indifferent, agree or strongly agree with a given statement), one speaks about ordered or ordinal logistic regression. The classical technique for estimating the unknown parameters is based on Maximum Likelihood estimation. Maximum Likelihood procedures are however known to be vulnerable to contamination in the data. The lack of robustness of this technique in the simple logistic regression setting has already been investigated in the literature, either by computing breakdown points or influence functions. Robust alternatives have also been constructed for that model. In this talk, the breakdown behaviour of the ML-estimation procedure will be considered in the context of ordinal logistic regression. Influence functions will be computed and shown to be unbounded. A robust alternative based on a weighting idea will then be suggested and illustrated on some examples. The influence functions of the ordinal logistic regression estimators may be used to compute classification efficiencies or to derive diagnostic measures, as will be illustrated on some examples.

Mitochondrial Chlamydomonas mutants for respiratory complexes present a decreased dark respiration and apparent yield of photosynthetic linear electron flow. They accumulate reducing power such as NAD(P)H and show lower levels of ATP. Under restrictive conditions, like sulfur depletion and anoxia, Chlamydomonas is able to produce hydrogen towards the activation of a chloroplatic O2-sensitive Fe-hydrogenase which catalyses the reduction of electrons to H2. In this study we used an adapted Melis protocol to analyse hydrogen evolution of mitochondrial mutants. For this aim a simple-flask system was built with gaz collecting tubes. A parallel flask was used for GC analyses. [less ▲]

Constructivist approach (Goldberg, 1995; Tomasello, 2003) considers that analogical reasoning is a cognitive process which underlies the abstraction of the linguistic forms and the construction of more abstract linguistic schemas. When children hear two utterances such as “John eats an apple” and “She sees a bird”, they can infer the abstract schema [Subject Verb Object] by realizing analogies between the two utterances. Morphosyntactic disorders encountered by children with specific language impairment (SLI) could be caused by problems with analogies, what would hinder their abstraction of construction schemas. Consequently, children with SLI would be less productive with their language and would use more fixed linguistic forms. Owing to these problems of generalization, the morphosyntactic development of children with SLI would be slow down [less ▲]

Previous studies (Lum et al., 2009; Tomblin et al., 2007; Ullman & Pierpont, 2005) have suggested that difficulties in the procedural learning system could contribute, in part, to the language difficulties observed in children with SLI. However, we have recently shown, with a classical serial reaction time (SRT) task, that children with SLI are able to learn implicitly non-linguistic statistical regularities (Gabriel et al., 2010). The aim of the present study was to explore whether children with SLI could learn similar statistical regularities with non-linguistic auditory stimuli. For this purpose, we compared performance of children with SLI and controls in two adapted SRT tasks: a visual SRT task and a non-verbal auditory SRT task. [less ▲]

This presentation proposal rests on empirical data collected through a European program named « Know and Pol ». The aim of our paper is to understand the process through which the recommendations emitted by the World Health Organization are translated in on-the-ground policy and practices in the Belgian mental health sector. As for many countries, these recommendations and the care model they promote contrast on several points with the practices and the structure of the Belgian mental health sector. One element advocated by the WHO has in particular raised controversies and oppositions: the necessity to replace the traditional hospital-centered model by community cares within small ambulatory structures. Therein lies the principal criticism addressed to the Belgian mental health cares policy. Through a focus on the reception of these recommendations and on a particular policy – “the therapeutic projects in mental health”, which can be seen as the last tentative to reform the organization of the sector –, we will analyze a process through which “big ideas” are translated in concrete policies. Indeed, in spite of the lack of legal constraint, these recommendations have proved to have some kind of normative capacity. Nowadays in Belgium, every text or policy discourse (held by politicians, civil servants or representatives of the field actors) concerning the mental health policy acknowledges the WHO’s recommendations and this, despite the fact that they could be seen as antagonist to some actors’ interests. In order to understand this evolution, we shall refer to the Michel Callon’s concept of “point of obligatory passage” which underlines the creative activity of the actors who do not just receive passively these norms but, on the contrary, who reinterpret and translate these ideas in new policy. Our presentation will underline (1) that in spite of the antagonism between those ideas and some actors’ constituted interests, notably the representatives of the hospital organizations, these actors may reinterpret WHO norms strategically so as to fit with their own interests and the organizational context they are involved in. (2) We assume that such an interpretive work is possible because these recommendations do not provide a clear way to act but, can be used in order to imagine “new possible worlds”. (3) By doing so, these actors are legitimizing WHO’s recommendations and are reinforcing the possibility for other actors to use them in order to elaborate and legitimize new policies. In conclusion, we’ll see that the process of reform and the influence of these norms are far from being direct and linear but, on the contrary, are long, iterative and constituted of “reinforcing loops”. At the methodological level, we’ll discuss the possibility to observe the multi-level process of elaboration of a policy through the materials (texts, declarations, evaluations…) produced and mobilized by the different actors. Indeed, with the interviews and observations, these materials constitute one of the major parts of our data collection. [less ▲]

In 2005, a reform aiming at reorganizing Belgian mental health supply around networks and care circuits organized along the needs of mentally ill persons has begun. The working conditions in mental health networks are experimented through the “therapeutic projects” and the “transversal dialog”. These two consultation devices offer an opportunity to observe the inner working of new policy settings which collectively entrust different actors, relying on political, administrative, professional or profane logics, with a reflexive mandate. This paper reports the results of a case study of the cluster “adults suffering from mood disorders” of the “transversal dialog”. The whole experiment realized on this scene is presented in three Acts that represent the successive steps of a translation (Callon 1986). Indeed, while the transversal dialog aims at producing hybrid knowledge on mental health sector, providing policy actors with relevant insights in the perspective of the reform, it constitutes a “stage” where the problematization of the mental health world is negotiated. However, the way policy actors have received the hybrid discourse produced by the field actors raise questions as to the actual objectives of the experimentation: does the transversal dialog produce knowledge on mental health sector or does it instil a culture of the controversy?

Various aquifers are studied in terms of low temperature geothermal potential. The feasibility and impact studies of these systems imply very often a numerical simulation of groundwater flow and heat transport. Nowadays, some finite element or finite difference codes are able to deal with such non linear simulations. On a synthetic case study and then on a real case study, a detailed comparative sensitivity analysis is performed using three different codes (MT3DMS, SHEMAT and HYDROGEOSHERE). For low temperatures and relatively small temperature changes, it appears rapidly that the uncertainty affecting values of the main hydrodynamic parameters (i.e. hydraulic conductivity) influences more the results than taking into account any coupling or non linearity. For a case study, the pumping and associated groundwater flow and heat transport are modeled in an alluvial aquifer interacting with a main river in order to assess feasibility of a low energy air cooling /heating system for a large office building. The worst case scenario corresponds to hot summer conditions simultaneously with river maximum temperature and the model leads to an optimization with intermittent pumping in minimum 6 wells. Numerical codes are ready to simulate complex groundwater flow, solute transport and heat transport situations in aquifers, however efforts must be realized to obtain reliable experimental in-situ measured values for the hydro-thermal properties.

Introduction: Lumbar pain among athletes is a common problem and can be challenging for athletic trainers and therapists. Unfortunately, little is known about the capabilities of trunk muscle function in elite athletes Therefore, an objective assessment of muscle performance is relevant in injury prevention and rehabilitation. The purpose of this study was to examine the specific trunk muscle strength and endurance in different sports i.e. swimming, rowing and tennis. Methods: We assessed maximum isometric trunk extensor, rotator, flexor and lateroflexor muscle strength as well as trunk extensor muscle endurance of 10 swimmers, 10 rowers, 10 tennismen and 10 sedentary students (control group). Strength was measured by means of specific trunk dynamometers. An adaptation of the Sorensen test was performed to assess trunk extensor endurance. Results: Muscle strength appeared generally higher among athletes than among control subjects. However, differences were statistically significant only with swimmers for trunk flexors (p<0.05) and trunk rotators (p<0.05), with rowers for trunk flexors (p<0.05) and with tennismen for dominant lateroflexors (p<0.05) and non-dominant trunk rotators (p<0.05). No significant bilateral difference appeared for trunk lateralflexors strength. For trunk rotators, tennismen were significantly stronger in the non-dominant side (p<0.05). Trunk extensor endurance was higher among rowers than among the other groups. Conclusion: This study underlined several differences in trunk muscle performance between athletes and control subjects as well as within athletes groups in relation to their sports. Further studies would clarify the full significance of these results with respect to performance and injury. [less ▲]

A new set of 725 NO limb profiles has been analyzed. The profiles have been deconvolved and inverted to get volume emission rates. Updates mean VER peak altitude is 115 km, in excellent agreement with PV results obtained 30 years ago. The corresponding average vertical intensity is 1.2 kR. The altitude of emission occurs at a higher altitude near the bright spot region than at larger distances (by about 7 km). The location of the statistical bright spot is the same as observed with PV (that is shifted dawnward by 2 hrs and slightly south of AS point). The nightside mean vertical intensity is between 0.4 and 1.8 kR, which brackets the values derived from the limb profiles. These results, coupled with other airglow measurements, provide constraints on global atmospheric circulation and vertical transport [less ▲]

Nowadays more than ever, dealing with risky scientific and technological issues requires careful attention and sustained policy-making support. In Western Europe, since the 1980s onwards, science and technology (S&T) issues are addressed in the institutional arena of Parliamentary Technology Assessment (PTA) offices. The main function of those PTAs is to increase the democratic accountability of S&T governance by providing the policy-makers and some stakeholders with intelligence on technological innovations and/or by enhancing social debate. Being based on literature research, participatory observation, official document analysis and qualitative data collection (through semi-structured interviews with academics and TA practitioners), we claim that the emergence and development of Parliamentary Technology Assessment offices (PTAs), leading/supposed to lead to an increased democratic accountability, embody a relevant indication of S&T governance becoming more reflexive. We offer case studies of several European PTAs and we are particularly interested in how much reflexivity is visible. After formulating two main dimensions of (reflexive) governance of S&T, openness to plurality and blurring of boundaries, we map the paths of these institutions over time along these two dimensions. Then, we argue than there appears to be a reflexivity pathway, on which some PTAs have moved farther than others. The empirical evidence for such a pathway to exist reveals the multiple features of democratic accountability fostered by one PTA setting or another, which may range from a managerial outcome (decision-makers are accountable) to a public outcome (citizens are accountable) and a professional outcome (scientists are accountable).

A new European frame has developed stepwise to manage the health effect of air pollution from particulate matter (PM 10 and PM 2,5), backed by an international body of scientific knowledge and OMS reports. The European Union CAFE Directive (2008) leaves the Member States with an important margin to translate the air quality objectives into action plans. In Belgium this policy is entirely left to the regions which developed different frames and decisional spaces. Belgium is a pollution 'hot spot' because of the variety of pollution sources it is faced with (traffic density, industrial density, transboundary pollution). As such, it provides an interesting ground for comparative research. We conducted a comparative research in the two largest Belgian regions and identified two decisional spaces that differ on a political, administrative and technical levels. Earlier research on risk management has pointed out that transversality, openness, and interdisciplinarity positively affect the quality of decision making under uncertainty. In that perspective, can specific tools help foster a transversal and integrative approach in air policy? In the Scope-project, a web-based tool using the Delphi method has been tested in the two regions. This allowed to put forward some hypotheses concerning the potential for transversality, interdisciplinary and openness in these different structures and decisional spaces. The results of the experiment and its potential for generalisation will be discussed at length. [less ▲]

In the setting of a maternal GBS-screening program and successful implementation of the strategy, efforts to improve screening for GBS status remain important. Critical factors that influence the accuracy of detecting GBS maternal colonization are the choice of culture media, the body sites sampled, and the timing of sampling. The evolution of the different culture options to improve the GBS-screening strategy will be reviewed. Despite efforts related to sampling and culture procedures, false-negative GBS-screening contributing to continuing EOGBS cases and false-positive screening leading to unecessary IAP, occur. As GBS carriage is highly variable, the predictive values of GBS antenatal cultures are not always good predictors of the maternal GBS status at presentation for delivery. Rapid non-cultural GBS screening methods have been developed: antigenic tests are not sensitive enough to replace antenatal screening cultures but available real-time PCR have faired better in the detection of GBS. Real-time PCR tests could improve effectiveness of the screening-based strategy and lead to a further reduction of the incidence of EOGBS disease. However questions of costs and logistics remain unanswered. Either for therapy or for intrapartum chemoprophylaxis, penicillin G for its bactericidal activity and narrow spectrum, remains the agent of choice. But in the true penicillin allergic patients, clindamycin or erythromycin have been recommended as alternative drugs. However, probably as a consequence of the important use of macrolides, related drug resistance among streptococcal isolates is currently recognized in many countries. Epidemiology of resistance to antimicrobial agents will be presented. [less ▲]

Studies about metallic reinforcements in historical monuments multiply themselves. Thanks to building archaeology and dendrochronology, we are able to determine the archaeological contexts to which the metallic elements belong and to date them. One of the objectives of the research is to list the different appearances of iron in roof frames and to identify the function of each. At the end, the principal aim is to create a typo-chronological inventory which will index all the iron reinforcements met in medieval roof frames of the Meuse basin (Belgium). [less ▲]

The use of new technologies and the merging of our libraries have led us to think about marketing our library services. At the same time, Belgian universities in the French Community decided to conduct the LibQual+ survey. We participated in the working group responsible for data analysis of this survey regarding our institution. This gave us an initial assessment of the level of user satisfaction in our library, pointing to general library strengths and weaknesses and highlighting several questions to be investigated further. We searched for alternative evaluation methods that could help us to validate the LibQual+ conclusions and to explore further certain issues regarding different library user groups (students / researchers / clinicians / academic professors). Methodologies for conducting focus groups, semi-structured interviews and participant observations are largely described in the literature. We propose to test and compare these methodologies in order to discover which method is the most appropriate for each type of user and how far these approaches may be complementary. We also want to verify whether these investigation strategies will lead to reproducible conclusions able to support strategic planning for the library. Lastly, we need to decide whether these methods could also be used to measure the impact of future marketing activities. It may be useful to share our working procedures, conclusions and experiences with colleagues involved in similar marketing challenge. [less ▲]

Additive technologies offer the possibilities to build complex geometries with integrated functionalities, specific to target application. 3D-printing of metallic powder is an additive technology proceeding in 2 steps: a green part is first built layer by layer by printing a liquid binder on the powder bed, and then green part is debinded and sintered. As sintering occurs separately of shaping process, 3D-printing is one of the only additive techniques able to produce porous parts, as filters or other fluid permeable components. Different porous characteristics can be obtained by playing on process parameters. [less ▲]

Governments and public authorities are increasingly relying on Public-Private Partnerships for the provision of public goods and services. It is often argued that the use of a public private partnership can relieve the government from a strained budget constraint and, in this paper, we analyze the choice of a contractual solution for designing, constructing and managing a project, with observable externalities, by a budget-constrained government. We show that the quality of the project and the designed contractor are affected by the extent of the budget constraint and we show that the use of a PPP may partially overcome the resulting inefficiencies.

Introduction – Lors de l’enregistrement du potentiel global d’action musculaire (PGAM) au niveau du muscle premier interosseux dorsal de la main (PID) après stimulation du nerf ulnaire au poignet, il est habituel d’observer un pic positif initial (pour une amplification d’environ 1 mV par division). Objectif – Déterminer l’origine de cette déflection positive précédant le PAGM du PID lors de la stimulation du nerf ulnaire au poignet. S’agit-il d’une réponse motrice générée au voisinage de l’électrode de détection active (champ proche) ? La positivité signifiant que les plaques motrices, où est générée cette réponse, ne sont pas exactement sous l’électrode active. S’agit-il, au contraire, de la captation d’une activité générée nettement à distance du système de détection (champ lointain) ? La positivité étant alors liée à l’orientation d’un dipôle électrique par rapport au système de détection. Sujets et méthodes - Dix patients successifs, indemnes d’atteinte du nerf ulnaire, sont étudiés. Une électrode active (G1) est placée sur le PID, au sommet de la saillie musculaire provoquée par le rapprochement actif du pouce et de l’index. L’électrode de référence (G2) est placée successivement sur le pouce, l’index, l’auriculaire, l’os trapèze au poignet et sur le membre controlatéral. Une stimulation électrique percutanée est appliquée au nerf ulnaire au poignet. Le muscle abducteur du Vème doigt (AB5) est également étudié (G1 au milieu de l’éminence hypothénar et G2 sur l’auriculaire). Résultats – Le pic positif précédant le PAGM du PID est en moyenne plus ample lorsque l’électrode de référence est placée sur l’index. Le PAGM du PID débute systématiquement par une déflection négative lorsque l’électrode de référence est placée sur l’os trapèze au poignet ou sur le membre controlatéral. L’absence de positivité initiale est associée à un raccourcissement de la latence distale motrice. Lorsque le gain des réponses motrices du PID et de l’AB5 est fixé à 0,1 ou 0,2 mV/division, quel que soit le muscle étudié et quel que soit le montage G1/G2 utilisé, toutes les déflections initiales (positives ou négatives) présentent une latence identique ou presque. Discussion – La déflection positive initiale qui précède le PAGM du PID, lorsque G2 est distale par rapport à la cathode, reflète l’activité générée au niveau des autres muscles innervés par le nerf ulnaire et notamment l’AB5. L’absence de cette positivité, lorsque G2 est proximale à la cathode ou sur le membre controlatéral, est liée à une inversion de polarité de la déflection initiale. Il en résulte, une réduction artificielle de la latence distale motrice. Ce type de référence doit donc être évité dans nos examens de routine. Conclusion – Ce travail souligne d’une part, l’importance de G2 dans l’enregistrement d’un PAGM et d’autre part, que les enregistrements de surface peuvent être influencés par la contraction de muscles situés à distance du couple G1/G2, même si un seul nerf est activé par la stimulation électrique percutanée.

La sensibilité à l'anxiété (AS)est la peur des sensations corporelles liées à l'anxiété. Plusieurs études constatent qu'une grande proportion de la variance de l'AS des filles et la totalité de la variance de l'AS des garçons s'expliquent par des facteurs environnementaux. L'objectif est de dégager, chez l'enfant au sein du milieu familial, les facteurs de risque et de protection de la sensibilité à l'anxiété (AS). Dans un premier temps, le lien entre divers états émotionnels des parents et la présence d'une AS chez leur enfant sera étudiée. La part contributive des mécanismes d'apprentissage (transmission d'information, renforcement, modeling) de l'AS lorsque l'enfant ressent des symptômes corporels sera également analysée. Différents effets seront testés: le type d esymptômes sur lequel l'apprentissage porte (douleur/anxiété), la source (père/mère) et la diversité des apprentissages. Dans un second temps, afin d'affiner les liens entre les états émotionnels des parents, les expériences d'apprentissage au sein du milieu familial et la présence d'une sensibilité à l'anxiété chez l'enfant, l'influence de deux modérateurs sera testée: l‘intelligence émotionnelle de l'enfant et les apprentissages sociaux. Les hommes apprennent qu'il est moins acceptable pour eux que pour les femmes d'exprimer leurs craintes. Les mères parlent plus volontiers de leurs inquiétudes et donc, lorsqu'elles présentent des manifestations anxieuses, elles peuvent plus facilement expliquer à l'enfant que ses peurs sont irrationnelles contrairement aux pères qui préféreront ne pas en parler. Que se passerait-il si le père parlait de ses craintes sachant qu'un père qui oserait exprimer sa détresse sera perçu de façon plus marquante par son enfant qu'une mère qui ose le faire? [less ▲]

According to us, it matters to situate the sustainable development in relation to the social responsibility and to the question of the different actors. It is in this particular context that we will analyse the relationship between the trade unions and the sustainable development in Belgium. We will show the involvement of the trade unions in relation to the three areas which define the sustainable development: the environment protection, the work quality and its organization and the benefit notion. This implication depends on the relations between the actors: state, company, workers (notably the trade unions). The question of sustainable development is culturally rooted and is linked to a certain conception of the economy and of the social contract. Obstacles are liable to appear during the appropriation of the sustainable development by the trade unions. The resolution of these difficulties is linked with the company management, the corporate culture and the type of negotiation. The trade union involvement depends on particular situations and specific contexts. We will therefore show that a systemic and contingent approach to the problem is required. [less ▲]

Les caractéristiques du langage adressé à l’enfant ont un impact important sur l’acquisition langagière, tant chez les enfants présentant un développement normal du langage que pour ceux qui ont des troubles langagiers. Mais, pour ces derniers, le bénéfice lié à un input optimal est plus important que chez les enfants sans trouble (Snow, 1994). Malheureusement, en raison même du retard de développement du langage, l’ajustement du langage de l’adulte à l’enfant est rendu plus difficile (D’Ordorico & Jacob, 2006). On se trouve dans une spirale négative : les enfants fragiles au niveau langagier dépendent plus que leurs pairs de la qualité de l’input qui leur est proposé et, à cause de leurs difficultés langagières, ils suscitent des interactions moins riches et moins à même de les soutenir dans leur développement langagier ultérieur. Face à ce constat, des programmes d’intervention ont été mis en place (Girolametto, Weitzman, & Greenberg, 2004). Dans ce travail, nous présenterons les résultats obtenus suite à une session de guidance parentale organisée avec les parents de 4 enfants d’environ 4 ans présentant un retard de développement de langage. L’objectif de cette formation est d’aider les parents à tenir un rôle d’acteur principal dans le développement langagier de leur enfant, en lui donnant des occasions de communiquer, en suivant ses intérêts, en le plaçant dans des routines prévisibles et familières, et en lui fournissant un langage plus adapté à ses difficultés. Dans un premier temps, chaque enfant a été filmé en interaction avec ses parents afin de disposer de mesures pré-thérapeutiques concernant le niveau langagier et communicatif de l’enfant et les stratégies d’interaction parentales. Ensuite, deux orthophonistes ont travaillé avec le groupe de parents afin de les familiariser aux stratégies utilisées dans les programmes d’intervention parentale. Ces stratégies sont les suivantes (Girolametto, 2004) : 1) les stratégies centrées sur l’enfant (par exemple, se mettre au niveau de l’enfant, attendre que l’enfant initie l'interaction) ; 2) les stratégies de promotion de l’interaction (par exemple, encourager l’enfant à prendre leur tour dans une interaction, à poser des questions) ; 3) les stratégies de modelage du langage (par exemple, l’expansion, la reformulation, etc). Enfin, deux séances de post-thérapie ont été réalisées, la première directement après la session de formation, la seconde 6 mois plus tard. Chaque film a été transcrit et analysé. Les résultats, qui seront présentés et discutés, ont des implications importantes en termes de prise en charge précoce des enfants présentant des troubles de développement langagier. [less ▲]

Towards the end of the 20th century, as the propagation of new discourses of ethnic success generated new versions of the American Dream, “America” came to signify not only immigrant mobility and whiteness, but also multiculturalism. As Inderpal Grewal argues in Transnational America, this paradox of sorts was only made possible through a slippage in the meaning of “white,” within which whiteness still connoted Anglo-America, yet extended its meaning to include a more heterogeneous group that passed as white through the endorsement of culturally-specific consumerist practices and middle-class norms of behaviour. Posing as multicultural yet covertly fastening whiteness to an ideal Americanness, these so-called “new” versions of the American Dream elevated the Asian American community to “model minority” status, thus contributing to rationalize away the lure that a “relative whiteness” could somehow be acquired by non-white minority groups. Drawing on whiteness studies and psychoanalytical theory, my paper will explore representations of interracial relationships as a means to claim and/or contest the ideal of whiteness in Mohsin Hamid’s The Reluctant Fundamentalist. In Hamid’s novel, the 9/11 attacks trigger a crisis in self-identification for model-minority protagonist Changez, which proves illuminating in terms of the invisible racial subjugation exerted so far onto him by Jim, Changez’s passport into the corporate world, and by Erica, his (white) lifeline to exclusive Manhattan. My paper will focus on the ways in which Hamid uses the post 9/11 context to reveal the racial melancholia surreptitiously informing today’s “new” versions of the American Dream, which is apparent in Changez’s and Erica’s relationship as well as in their parallel impossible mourning of the broken mirror of “white” Am/Erica. Emphasizing the extent to which whiteness and racial melancholia permeate the discourse of assimilation, Hamid’s book rewrites the “new” American Dream as a “fantasy built on absences” (Anne Anlin Cheng).

In Parkinson's disease, altered activity in posterior associative cortices has often been associated with dementia. It remains to be determined if this pattern is a reliable marker of a progression toward dementia in patients without demonstratable dementia. In this retrospective analysis, we used positron emission tomography to study resting-state cerebral fluodeoxyglucose uptake in 8 healthy controls and 8 Parkinson's disease patients who did not have evidence of dementia at the time of assessment. For those patients, clinical follow up was available and we know that they did not meet dementia criteria on average 10,37 years after assessment. The results show that patients had reduced fluodeoxyglucose uptake mostly localised in the right hemisphere and including precuneus, superior temporal, middle temporal and inferior parietal cortices. It also includes right insula. These cerebral activity predominating in posterior cortices is present in non-demened patients but is not always predictive of dementia within the 10,34 years.

Nowadays, collision avoidance (CA) systems are an intensive research topic since the majority of all traffic accidents are collisions that are caused due to inattention or unadjusted driving behaviour of the driver. Up to date prototypic CA systems are based on on-board environmental sensors, such as camera or radar systems, in order to scan the vehicle’s surrounding for potential crashes. The functionality of the used sensors under varying environmental conditions and the limited sensor covering area require an enormous effort to ensure a reliable detection of obstacles, and thus limit the application of the systems. In order to expand the operating field of such systems, a GALILEO-based CA system will be developed within the project GALILEO-above. This advanced driver assistance system detects surrounding vehicles that are on collision course, and react autonomous, if the driver does not intervene to avoid the crash. For this purpose the system initiates an emergency stop or an emergency steering. For the development of the CA system the GALILEO test centre “Automotive Gate” in Aldenhoven, Germany will be used. On this test area pseudolites will be installed which provide GALILEO-like navigation signals. Thus, the development respectively tuning of GALILEO based vehicle systems will be enabled, so that they are available on the market when the GALILEO satellite system becomes operative. At the end of the project GALILEO-above, first prototypes should demonstrate the potential of GALILEO-based collision avoidance systems. In this paper the GALILEO-above project will be introduced followed by a detailed description of the development process of the CA system. Furthermore, first results will be presented. [less ▲]

Pharyngo Laryngeal Reflux (PLR) influences the voice quality : hoarseness, vocal fatigue and hypertonia (Shaw et al, Hopkins et al). Our goal is to measure the influence of the PLR on the voice of 96 subjects by using the Belafsky’s reflux symptom index (RSI) and reflux finding score (RFS). 46 dysphonic patients (26M/24F) constitute the experimental group (EG) and 50 subjects (13 M/33F) without vocal or gastric complaint the control group (CG). All are evaluated by subjective measures (RSI), D-type scale (DS-16, Denollet et al) and objective measures (Video Laryngo Stroboscopy, RFS). The EG shows a RSI score significantly higher on test than on the retest (p=0.002). The specificity of the RSI calculated on the CG amounts to 98 % (chi ²: p < 0,05, Cramer: 0,678). The EG scores are significantly higher than those of the CG (p=0,000) although the CG obtains scores significantly higher as for the eating risk habits (p=0,001). In the EG, we note a correlation between the coffee consumption, the item 9 (pyrosis) (rho: 0,32; p < 0,05 ) and the global RSI score (rho: 0,35; p < 0,05). In the CG, alcohol consumption influences significantly the item 9 (rho: 0,47). The correlations between RSI and RFS are not significant (p < 0.05). The ENT evaluation is severe and probably influences the result. We observe no influence of the gender and of the D-type scale on the RSI scores (p <0.05). The RSI scale is an interesting tool for the detection of RPL. [less ▲]

The term empathy refers to two related human abilities: mental perspective taking (cognitive empathy) and the vicarious sharing of emotions (emotional empathy). The main object of this study was to explore the relationship between capacities of both aspects of empathy and their relationships with interpersonal difficulties in alcohol-dependant patients (AD). The research in alcoholism empathy has focalised around one aspect of cognitive empathy - the capacity to infer an emotional state-, and that essentially on the basis of emotional facial expression (EFE) recognition. However, researchers have shown little interest in the investigation of the other aspects of cognitive empathy. The present study focuses on the capacity to infer interpersonal intentions and on emotional empathy. As documented by the research on EFE decoding, AD patients show deficits in cognitive empathy. In this study, we investigated their capacity to infer interpersonal intentions in social situation. We hypothesized that AD patients compared to healthy individuals and to depressed patients will attributed more intentions of reject and of aggressiveness to other people on the basis of their EFE. In this study, emotional empathy was defined as the modulation of the emotional feeling state of the participant in function of the EFE display by other people. We hypothesized that the modulation in AD patient will be different from the one of healthy people in function of the Cloninger subtype of alcoholism (Cloninger, Bohman, Sigvardsson, 1987). This emotional reactivity will be more important in Type II alcoholism and less important in Type I alcoholism. As Mimicry facilitates feelings of empathy in healthy people, it was also investigated. Twenty type I AD patients, 20 type II AD patients, 20 depressed patients, and 20 healthy subjects participated to the study. The alcoholism subtype identification was maid according to the criteria from von Knorring, Bohman, von Knorring, and Oreland (1985). The participant completed questionnaires assessing the quality of interpersonal relationships, their usual quantity of alcohol consumption, and, for AD patients, their level of alcohol dependence. Their capacity to recognise faces was evaluated by the Benton facial recognition test. The empathy tasks were computerized. In the cognitive empathy task, the participants had to evaluate the adequacy (in a 7-point Likert scale) between a film of a face changing from a neutral EFE to an emotional EFE (the photographs come from the material of Matsumoto & Ekman, 1988) and an adjective descriptive of personality. Each adjective was weighted on the interpersonal dimensions of reject, aggressiveness, dominance, and affiliation. In the emotional empathy task, the participants had to evaluate their own emotional feeling state (in a 7-point Likert scale; from very negative to very positive) after watching a series of films depicting emotional faces (same material as before). During this task, the participant’s face was filmed in order to assess mimicry. The differences of empathy capacities between AD patients and control participants (depressed and healthy) are discussed in reference to the characteristics of their interpersonal relationship.

Socially anxious children have difficulties to interact adequately with others. The core characteristic of social anxiety, the fear of being negatively evaluated by others, may among others, be based on problems with the decoding of other persons’ emotional facial expression (EFE). Up to now, the research on EFE recognition in socially anxious children has produced mixed results. Whereas some studies reported differences between anxious and healthy children in EFE recognition (e.g., Simonian, Beidel, Turner, Berkes, & Long, 2001), others didn’t find such differences (Melfsen & Florin, 2002). In this study, we addressed two new issues in the investigation of EFE recognition in socially anxious children. Firstly, we investigated self-esteem. Socially anxious children show low confidence in one’s cognitive and social abilities. Furthermore, high self-esteem is related to high capacities of EFE recognition (Garfield, Rogoff, & Steinberg, 1987), and more generally to high level of social functioning (Serretti et al., 1999 ; Shapira et al., 1999). Indeed, the perception of ourselves depends on the way we think others people perceive us. Secondly, past researches have investigated this issue in low anxious situations and thus, not in situations in which social anxious individuals feel threatened. The originality of the present study is that it addresses the relationship between EFE recognition performance and self-esteem in children placed in an anxious social situation. We predicted a low capacity to decode EFE in socially anxious children. Moreover, we hypothesised a relationship between a low self-esteem and difficulties to decode accurately EFE in an anxious social situation. Seventy children (8 – 12 years) were placed in an anxious social situation of performance in which they were instructed to count aloud backwards, beginning at 200 in increments of 13. Children assessed their emotional feeling state, including their degree of anxiety, before and after the anxious social situation. Furthermore, children were assessed on an EFE decoding test consisting of 16 photographs depicting EFE of happiness, anger, disgust, and sadness. For each photograph, they evaluated the presence of nine types of emotions on a 7-point Likert scale. They also completed the Self-Perception Profile for Children (Harter, 1985). No correlations emerged between the accuracy of EFE recognition and an increase of anxious feelings after the anxious social situation. However, self-esteem was correlated with performance on the EFE recognition test, r (70) = -.33, p < .01. Moreover, the lower the child’s level of self-esteem was, the more he/she perceived negative emotions (fear, anger, disgust, and shame) in EFE of anger. In conclusion, social anxiety doesn’t seem to interfere with EFE recognition performance in an anxious social situation. However, low level of self-esteem in children appears to be associated with deficits and interpretative bias in EFE recognition in an anxious social situation. The recognition of the expression of anger, an emotion socially threatening, seems particularly biased in children with low level of self-esteem. [less ▲]

Computation of lactation yields from test-day data has lost much of its importance for genetic evaluations as the use of test-day models is currently quite widespread. In the other hand its interest for intra-farm management is increasing as a base for advanced management tools. The first and principal aim of this study was to develop a method which takes into account advantages and disadvantages of existing methods, and to test its potential to provide useful management tools to dairy farmers. A test-day model with modifications to able daily run and management tools was developed. Because of its similarities with best prediction, the method developed here was called modified best prediction. The second objective was to compare the accuracy of this new method with best prediction and test interval methods. Modified best prediction showed good results for predicting daily yields and was slightly better than best prediction for lactation yields prediction. Management tools obtained with modified best prediction are explained. [less ▲]
