In this talk, we discuss an extension of the strong axiom of revealed preferences to collective households. The question that we address is whether a set of observed consumption baskets can be decomposed in such a way that each of the derived data sets reflects the choices of a “rational” (i.e., utility-maximizing) individual member of the household. Although testing revealed preference axioms on data generated by a single decisionmaker can be done in polynomial time, the extension to two-member households is NP-complete. We propose two algorithms for testing the collective consumption model on large data sets. The first one is an exact algorithm based on a new mixed-integer programming formulation, whereas the second one is a heuristic based on a simulated annealing procedure that solves a global optimization formulation of the problem. Computational experiments are performed on real-life data. [less ▲]

La Lozana andaluza describes the story of a gifted prostitute which adventures occur in Rome before the Sack of 1527. However, the writer, an Andalusian priest, fills his text with biblical references. As the purpose of his Portrait gives rise to debate and is valued according to its (un)appropriateness to the Christian doctrine, we study the role of the biblical intertextuality in the determination of this purpose. Indeed, in La Lozana, the biblical hypotext presents its traditional function as an auctoritas but it also constitutes a favored tool of linguistic games, a source of comic effects, and supplies the framework of the Portrait. In this work we examine the mixed intertextuality used by an autor which anticlericalism was sometimes interpreted as an erasmist feature. Consequently, we highlight, always making links with the biblical marks of La Lozana, first some evidences that make an orthodox interpretation possible, and later some dissident tendencies that cross the story. The biblical intertextuality produces a duplicity of the discourse that prevents an univocal interpretation. In fact, this posture is understandable during a time which is disturbed by religious tensions. [less ▲]

De nombreuses études montrent que les pères ont un rôle influent dans la prise de décision des femmes d’allaiter leur enfant, et que leur soutien est crucial pour le succès de l’allaitement dans la durée. Or ils sont peu préparés à ce rôle et souhaiteraient davantage de soutien dans cette expérience. Les recherches menées montrent que si la plupart des pères, pendant la grossesse, ont une représentation positive de l’allaitement et veulent être impliqués, la confrontation avec la réalité est souvent difficile (difficultés d’allaitement inattendues, pression et contradictions de professionnels de santé tournés sur l’aspect technique de l’allaitement, place limitée auprès de l’enfant,…). Après le retour à domicile, les sentiments des pères vis-à-vis de l’allaitement sont très divers et semblent liés à la place qu’ils prennent dans la triade, modulée parfois par la place que leur laisse la mère de l’enfant. Certains pères vivent un sentiment d’exclusion, d’autres se voient comme un « membre de l’équipe allaitante », trouvant d’autres manières de s’impliquer avec leur enfant. Le soutien apporté aux mères prend différentes formes : direct et indirect, verbal et non-verbal, émotionnel et instrumental. Selon les mères ce soutien est essentiel, davantage encore dans certaines situations (primiparité, césarienne, difficultés d’allaitement, fatigue, retour au travail). De leur côté les pères ont besoin d’une reconnaissance de leur rôle par leur partenaire d’une part, par les professionnels de santé d’autre part. Un système de santé « ami des pères » doit impliquer les pères précocement et de manière effective, pour les aider à soutenir leur partenaire dans l’expérience de l’allaitement. [less ▲]

Frictional resistance is an important part of the total resistance of a ship, especially when the Froude number is small. There exists different ways to reduce it, like riblets, polymer injection, air lubrication and air cavity. The first two techniques are hard to implement for full-scale ships. The air lubrication is subjected to plenty of research for around twenty years and could lead to resistance reduction up to 80%. Unfortunately, full-scale tests do not present the same results. The principle of air cavity ships is quite different, in the sense that air is blocked under the hull. The system exists for more than 100 years, but does not seem to convince the naval architects, although it can reduce the resistance up to 20%. The problem is that it can increase the resistance. Better knowledge of the phenomena is then necessary. [less ▲]

Brentano’s views on psychology influenced the way philosophy was made at the beginning of the 20th century. But did this influence spread as far as to give place to Freud’s revolutionary discovery of the psychoanalytical unconscious? We know that Sigmund Freud attended enthusiastically Brentano’s lectures between 1874 and 1876. Yet, since Brentano’s name is never mentioned in Freud’s later, properly psychoanalytical writings, there is a very convincing argument for stating that Brentano had no lasting influence on Freud. Furthermore, Freud’s theory of the unconscious doesn’t seem to continue, but rather to oppose Brentano’s psychological views. Yet, as it was shown lately by a number of philosophers there are reasons to believe that Brentano had a profound influence on Freud. An attentive analysis of Freud’s vocabulary as well as his arguments against “philosophical” objections supports this point rather convincingly. However, Freud was not a philosopher and Brentano’s historical influence does not suffice to transform the Freudian unconscious in a philosophical concept. It is the purpose of this paper to sketch a way to make a philosophical use of Freud’s unconscious by reconstructing the dialogue between Brentano and Freud on a conceptual level. First, I will explain the differences between Brentano and Freud’s psychology. While Brentano and even the most original of his students thought the mind is entirely conscious, and they only called “unconscious” certain intermittences of this consciousness, Freud’s metapsychology rests on the supposition that the mind is primarily unconscious and it is consciousness that appears locally as a quality of certain mental events. In the second part of my paper I will show that this opposition is not as radical as it seems. Freud’s metapsychological supposition of an unconscious mind is not merely stated but proven by clinical facts. And these facts allow Freud to substitute a dynamic approach of the mental to a descriptive psychology of Brentanian inspiration: a mental state is only conscious because it becomes thus by passing from an unconscious to a conscious state. It is this change in the point of view that allows Freud to see mental events as processes rather than mere states. Thus, the results of Brentano’s descriptive psychology are not denied but rather completed by Freud’s dynamic theory of the unconscious. The purpose of this paper is thus to clarify not only Freud’s historical relation to Brentano, but also the relation of his metapsychology to Brentano’s descriptive psychology and to all psychology that takes Freud’s discovery of the unconscious seriously. Despite the explicit critique of the unconscious that we find in the Psychology from an Empirical Standpoint, I think that Freud never truly opposed Brentano. He rather took Brentano’s descriptive psychology a step further: he introduced a dynamic component to the analysis of the psyche that could throw light on the blind spots in Brentano’s psychology.

There is now growing consensus about the importance of building and strengthening national monitoring platforms in order to facilitate the evaluation of large-scale health programmes and initiatives in low- and middle-income countries [see the paper published in 2010 in The Lancet by Victora et al.]. This is also crucial for improving accountability, which is defined by the United Nations' Commission on Information and Accountability for Women's and Children's Health as a cyclical process of monitoring, review, and (remedial) action. The International Health Partnership and related initiatives (IHP+), World Health Organization and other partners have recently developed guidelines to support country-led platforms for monitoring, evaluation and review of national health strategies. The national Compacts promoted in the framework of IHP+ offer an excellent opportunity to foster the development of such country-led platforms for information and accountability. Indeed, a Compact formalises the commitments of the recipient government and health sector partners to increase financing efforts in the health sector, to respect aid effectiveness principles and to support the national health policy and strategies in a common planning, coordination, and monitoring & evaluation framework. IHP+ is also closely connected to initiatives such as the Health Metrics Network that aims to improve the quality of health information in developing countries. We propose to analyse how the Ministries of Health in four Francophone Western African countries (Benin, Burkina Faso, Mali and Senegal) have seized the opportunity of IHP+ to strengthen their monitoring and accountability platforms, and assess what further actions could be taken in the future. We present a comparative analysis grid filled on the basis of the experience of the co-authors in supporting the process in the four countries. This composes the first step of an on-going research and experience sharing project supported by GRAP-PA Santé. [less ▲]

OBJECTIVES: This study evaluates the impact on voice of a 2-hour reading task between 70-75 dB(A) in 16 normophonic and 16 dysphonic female teachers with vocal nodules. METHODS: Objective measurements (acoustic analysis, voice range measurements, aerodynamic measurements) and subjective self-ratings were collected before the task and every 30 minutes during the reading to determine the voice evolution in both groups. RESULTS: Fundamental frequency, lowest frequency, highest frequency (F-High), highest intensity and intensity range increase through the reading, whereas Shimmer decreases. Maximum phonation time decreases after 30 minutes. Estimated subglottal pressure (ESP) and sound pressure level increase during the first hour. Afterwards, ESP decreases. Self-ratings worsen through time. When comparing the normophonic and the dysphonic teachers, self-ratings reveal more complaints in the dysphonic group. Few differences in objective measurements are found between both groups: normophonic teachers show lower ESP, higher F-High and greater frequency range. CONCLUSIONS: Frequency modifications from acoustic analysis and voice range measurements suggest an increased laryngeal tension during vocal load, while subjects perceive a worsening of voice. Aerodynamic parameters depict first a deterioration of voice efficiency and then an adaptation to the prolonged reading. The comparison between both groups shows a discrepancy between objective measurements and self-ratings, suggesting that both approaches are necessary to have a complete view of vocal load effects. Surprisingly, both groups behave similarly through vocal load, without more or quicker deterioration of voice in the dysphonic group. [less ▲]

Agricultural crops became through years an attractive option to increase European energy independence. Brazil has taken this opportunity since the seventies by using sugar cane bioethanol as vehicle fuel. The development of biofuels production is more recent in Europe. Due to temperate climates, bioethanol production is mostly based on wheat and sugar beet, this latter being considered as the ‘equivalent’ sugar crop to sugar cane for Europe. Biofuel is the most common application of bioethanol but its transformation into bioethylene through a dehydration step and then its polymerization into bioplastic can be an alternative as already found in Brazil. This paper will consider both potential uses and compare them using Life Cycle Assessment methodology. Common boundaries of the systems comprise the cultivation step for both crops, i.e. sugar cane and sugar beet, with all associated energetic and fertilizer consumptions, the transportation step from field to the industrial plant, the sugar crops transformation into hydrate bioethanol, the by-products valorisation and the specific end-of-life. For the biofuel scenario, a dehydration step using molecular sieve is added to get anhydrous bioethanol. For the bioethylene scenario, industrial dehydration and polymerization steps are added. Direct comparison between both scenarios is not possible due to different products uses. The comparison was then performed for both scenarios between the bio-based product and its fossil equivalent. ReCiPe 2008 method was used at midpoint level to get the environmental impacts. As expected, the impact of bio-based products in climate change and fossil fuel depletion categories decreases compared to the fossil counterparts. For other categories, difference is less significant and results are often better for fossil products. Land use change impact was implemented to assess its importance. Depending on assumptions, the greenhouse gas emissions from crop implementation on a natural land can counteract the previous mentioned benefits. To get an idea of the performance of each considered bioethanol use, a single score relative to the amount of sugar cane and sugar beet cultivated on one hectare was calculated using the endpoint level of ReCiPe 2008 methodology. The environmental gain was then evaluated comparing the bio-based product use with the classical one. The highest performance was obtained for the bioplastic scenario based on sugar cane followed by the sugar beet bioplastic. The E5 biofuel based on sugar beet reaches a slightly lower gain. The E85 fuel obtains less gain due to the higher amount of biofuel needed to drive the same distance as using fossil fuel. When taking the land use change into account, the best gain is given by the sugar beet bioplastic. On the one hand, this study shows the importance of assumptions, especially in the agricultural field, on the obtained results. On the other hand, it points out that considering bioethanol as a chemical intermediate and not a fuel can be better from an environmental point of view. [less ▲]

Straw bales technology for buildings is developing in Belgium as in many other countries. The market is growing but significant uncertainties are left concerning how to model its dynamical hygrothermal performances and its long term behaviour. The present paper presents the preliminary analysis conducted on material parameters and component’s response to dynamic heat and moisture solicitations. The simulations use WUFI Pro software based on material parameters form literature and both reference climate files for Belgium and theoretical climates to analyse the interactions between straw bale walls and finishing materials and their influence on component performances and durability. A specific prefabricated wall element sold on Belgian market is detailed and introduced in simulations. The influence on comfort feelings and indoor air quality are discussed with a focus on component´s thermal inertia and moisture regulation capacity. The paper concludes with recommendations on wall composition to help straw bale technologies to develop in building market of Belgium and other countries. [less ▲]

Située dans la partie Sud-Ouest du Niger, le bassin de Dargol appartient à la région de socle précambrien du Liptako. L’étude du chimisme des eaux souterraines révèle trois types de faciès dont le plus dominant est le type bicarbonaté calcique à magnésien (65%). Environ 47% d’ouvrages ont des teneurs en nitrates dépassant largement les normes OMS (50 mg/l). Les teneurs en isotopes stables (δ18O, δ2H) de la nappe indiquent deux mécanismes de recharge: une recharge directe par les eaux des pluies peu ou pas évaporées, et une recharge indirecte par les eaux évaporées issues des lits de koris et des eaux de surface. L’analyse des teneurs en tritium de la nappe indique que la recharge est récente pour la majorité des points investigués. En revanche, dans le secteur à faibles teneurs en tritium, le taux de renouvellement semble être faible voire nul. [less ▲]

We introduce the concept of constant 2-labelling of a weighted graph and show how it can be used to obtain periodic sphere packing. Roughly speaking, a constant 2-labelling of a weighted graph is a 2-coloring (black and white) of its vertex set which preserves the sum of the weight of black vertices under some automorphisms. In this manuscript, we study this problem on weighted complete graphs and on weighted cycles. Our results on cycles allow us to determine (r,a,b)-codes in Z^2 whenever |a-b|>4 and r>1. [less ▲]

Abstract The alluvial plain of the Kou basin is located in the southwest of Burkina Faso. In this basin, the main surface water resource for agricultural needs is constituted by a small perennial river, but in recent years this resource is insufficient to satisfy the uses in agriculture. The alluvial plain which extends from either side of this river banks is expected to have the potential for constituting an alternative water supply for agricultural needs. However, the characterisation of the alluvial plain is still superficial though the plain extension and the nature of the deposits are roughly known. The objective of this study is to improve the characterisation of the alluvial plain, in particular the heterogeneity and the thickness of the deposits, using geophysical methods, namely Electrical Resistivity Tomography (ERT) and Horizontal and Vertical Spectral Ratio (H/V SR). The ERT and H/V SR methods are non invasive geophysical techniques, simple, efficient, robust and easy-to-use geophysical tools in alluvial environment based respectively on the soil resistivity and the resonant frequency of superficial materials. In upstream of the alluvial plain, near the river, these methods were used to map the sandy to sandy-thin deposits (0-5m) and the unfractured bedrock. Downstream they highlight fractured and deconsolidated bedrock drawing a V-shaped geometry of deposits. This geometry is due to the faults and the magmatic intrusions. The bottom of the V-shaped would be filled mainly by fractured/deconsolidated bedrock materials and the edges by the clay and laterites deposits. The alluvial plain would be relatively thicker downstream of the study area (approximately 30 to 50m). A correlation is obtained between ERT images and resonance frequencies determined on the H/V profiles. From a hydrogeological point of view, downstream of the study area, the alluvial plain would constitute an important aquifer with a high porosity and thick deposits. This aquifer could be easily accessible with rudimentary structures (such as sumps) and could constitute a supplementary water source, for irrigation activities in this second region of Burkina Faso.

L’évaluation de l’état actuel de la qualité des eaux de la nappe du Continental Terminal et du fleuve Saloum a été réalisée grâce à l’analyse de 44 échantillons d’eau souterraine et 3 échantillons d’eau de surface collectés en saison humide. Les analyses des ions majeurs et les mesures de la conductivité électrique (CE) ont démontré que les eaux de la nappe du CT du Saloum étaient largement contaminées par la salinisation (CE comprise entre à 750 et 2800 µS/cm) au niveau de la zone côtière à l’ouest et au nord sur une bande longeant le fleuve Saloum. Dans ces zones, les eaux ont désormais des faciès chimiques chlorurés sodiques venant de faciès au départ bicarbonatés calciques des eaux souterraines peu contaminées. Au niveau de certains points, la composition des eaux souterraines devient sensiblement la même que celle des eaux du fleuve Saloum. Les diagrammes binaires (Na versus Cl, Na/Cl versus Cl, [Ca + Mg] versus HCO3 et [(Ca+Mg) - (HCO3+SO4)] versus (Na-Cl)) ont permis de définir les processus géochimiques et les phénomènes de mélange impliqués dans la minéralisation des eaux.

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. This expression profile prompted us to evaluate the role of SoxE genes in cochlear cell terminal differentiation. Analysis of Sox10 knockout mice showed that it is dispensable for prosensory domain formation but that it is required for its maintenance. Indeed, we observed a significant shortening of the cochlear duct. However, Sox10 does not seem to play a role in cochlear cell fate since cell patterning is not affected in knockout mice. In parallel, we analysed the role of Sox9 in cell specification using both gain- and loss-of function approaches. We demonstrate that Sox9 strongly inhibits hair cell fate even when it is forced by ectopic expression of Atoh1, a potent inducer of hair cell differentiation. Accordingly, Sox9 expression needs to be downregulated in cells that are committed to become hair cells as it was observed in the developing inner ear. To confirm the role of Sox9 in vivo, we also analysed inner ear cell patterning in Sox9a-/-, Sox9b-/- and double knockout zebrafishes at different developmental stages. In parallel, we are investigating the molecular mechanisms underlying Sox9 inhibitory effect on hair cell fate in UB/OC1 cell line and more specifically its relationship with other important factors for cell specification in the organ of Corti such as Sox2, Notch pathway or Atoh1. Taken together, our work is shedding a new light on the role of soxE genes during inner ear development, specification and maintenance of differentiated cells within the cochlea. [less ▲]

The non-energetic valorization of renewable resources using efficient and eco-friendly methodologies is the central axis of the “green chemistry” concept. In particular, the chemical conversion of carbohydrates arising from the hydrolysis of non-edible vegetable feedstock (i.e., lignocellulosic biomass and streams) is a widely explored thematic for the production of new high-added value materials. In this context, we report here on the development of a microwave heating methodology for the efficient production of carbohydrate-based and lignin-based chemicals with relevant antioxidant and surface-active properties. New effective synthetic protocols minimizing wastes and energy-consumption are proposed. Enhanced yields and selectivities are achieved after a few minutes of microwave heating using heterogeneous catalysts. The benefits of this microwave approach are highlighted in terms of yields, atom efficiency, environmental factor, and carbon efficiency. Up-scaling assays are also discussed. [less ▲]

In a rapidly changing world, human activities offer opportunities for many plant species to colonize new areas. Increasingly, it is recognized that colonization can be accompanied by different ecological and evolutionary processes, acting over relatively short periods of time. When populations colonize novel environments, individuals’ phenotypes will depend on a combination of different, non-exclusive processes, including phenotypic plasticity (PP), local adaptation (LA), environmental maternal effects (EME) and genetic drift (GD)(Monty and Mahy 2009b). Despite these processes have long been studied independently, few attempts have been made to simultaneously address the importance of those processes in plant colonization. Here, we present a set of related studies aiming at disentangling the role of PP, LA, EME and GD in Senecio inaequidens (Asteraceae) in southern France, where it was introduced at a single wool-processing site in the late 19th century. We used seeds from populations growing in contrasted climates to explore the phenotypic variation related to climate. We performed several common garden experiments (Monty et al. 2009, Monty and Mahy 2009a, 2010), as well as a reciprocal sowing experiment with gardens under Mediterranean and Pyrenean climates (Monty et al. in revision). We analyzed climatic phenotypic variation in germination, growth, reproduction, leaf physiology and survival. We characterized genetic structure in the studied populations using AFLP. We found consistent genetic differentiation in growth traits but no home-site advantage, thus weak support for LA to climatic conditions. In contrast, genetic differentiation showed a relationship to colonization history. PP in response to climate was observed for most traits, and it played a particularly important role in leaf trait variation. EME mediated by seed mass influenced all but leaf traits under harsh climate. Heavier, earlier-germinating seeds produced larger individuals that eventually produced more flower heads throughout the growing season. However in a milder climate, EME were negligible. Our different studies suggest that phenotypic variation in response to climate depends on various ecological and evolutionary processes associated with geographical zone and life history traits. Therefore, we argue that a “local adaptation vs. phenotypic plasticity” approach, as often considered in the literature, is not sufficient to fully understand what shapes phenotypic variation and genetic architecture of colonizing populations.

On the Antarctic continent, cyanobacteria produce conspicuous benthic microbial mats in lakes, from the coastal regions to the mountains (till 84°S). However, little is known about theirl biodiversity in comparison with other regions of the world. The BelSPO project AMBIO aimed to test whether (i) microbial communities are structured by the same factors as those shaping communities of macroorganisms, and (ii) endemism among cyanobacteria does exist. We have analyzed the cyanobacterial biodiversity in a variety of aquatic habitats from the three main biogeographical regions (Continental, Maritime Antarctica and the Sub-Antarctic) and determined the ‘baseline’ data needed to understand the contribution of various processes that are responsible for the distribution patterns.

Background: In cardiac surgery, acute kidney injury (AKI) is a severe postoperative complication and associated with increased rates of mortality, morbidity, and length of stay in intensive care units (ICU). It occurs in 5% to 30% of patients depending on the definition used [1] [2] [3]. The aim of this study is to present an overview of AKI following cardiac surgery associated or not with cardiopulmonary bypass, in our center. Methods: This retrospective study includes patients treated by cardiac surgery from April 1st, 2008 to March 31th, 2009 in a single center. We selected patients who underwent on-pump coronary artery bypass surgery (CABG), off-pump CABG (OPCAB), aortic valve replacement, mitral valve repair or replacement and aortic valve replacement combined with CABG. Patients undergoing renal replacement therapy preoperatively were excluded. The RIFLE classification (Risk, Injury, Failure, Loss and End stage kidney disease) allowed stratifying the patients into the 3 grades of AKI severity. The stratification was based on the most pejorative element observed within 7 days after surgery: increased serum creatinine level or decreased urine output, or decreased glomerular filtration rate according to criteria of Bellomo [4]. Occurrence of AKI was studied by type of cardiac surgery as its impact on the length of stay in ICU and in the hospital. Proportions were compared by the Chi-square test and median values by the Mann-Whitney U test. Results were considered significant at p < 0.05. Results: Four hundred and thirty-four patients were included: median (IQR) age 69.0(60.0-76.0) year, 30.2% females, 2.76% urgent/emergent cases. Fifty-eight patients (13.4%) underwent OPCAB, 182(41.9%) on-pump CABG, 104(24.0%) aortic valve replacement, 44(10.1%) mitral valve repair or replacement and 46(10.6%) aortic valve replacement combined with CABG. AKI occurred in 213(49.1%) patients: 79(37.1%) “Risk”, 108(50.7%) “Injury” and 26(12,2%) “Failure”. Distribution of AKI by type of surgery was equal to 36.2% among OPCABG, 44.0% on-pump CABG, 49.0% aortic valve replacement, 52.3% mitral valve surgery and 82.6% aortic valve replacement combined with CABG, respectively. AKI occurrences differed significantly according to the type of surgery (p<0.0001). Lengths of stay in ICU were significantly longer (p<0.0001) in AKI group compared with non AKI group: 3(2-4) days versus 2(2-3) days. However, no difference (p = 0.65) was observed between the two (AKI and NON-AKI) groups in hospital length of stay: 13(10-18) days versus 12(10-16) days. Conclusions: The incidence of AKI is very high in this population as compared to the literature. This may be due to the fact that the three elements of the RIFLE classification for all the population studied have been used. This study emphasizes the need for clear definition of AKI in order to compare different studies adequately. AKI after cardiac surgery with cardiopulmonary bypass would be further studied in order to develop more appropriate preventive measures. [less ▲]

The weighted likelihood estimator of ability (WLE, [3]) was introduced as an asymptotically unbiased estimator of ability in item response theory (IRT) models. Moreover, its standard error was shown to be asymptotically equal to that of the maximum likelihood (ML) estimator [2]. Although this asymptotic framework is most often encountered in psychometric and educational studies, there are several practical applications for which an "exact" formula for the standard error would be useful. For instance, such a formula would certainly be convenient at the early steps of a computerized adaptive test (CAT), whenever only a few items are administered. The purpose of this paper is to derive two possible formulas for the standard error of the WLE, by starting from the objective function to be optimized and deriving the standard error in a similar approach of the ML framework (see e.g., [1]). The two potential formulas are then compared through both, a small simulation study and a practical analysis with realistic, yet arti cial data. It is concluded that one of the formulas must be preferred to the other, both for mathematical consistency and on the basis of the simulated results. References [1] Baker, F. B., & Kim, S.-H. (2004).

This paper aims at analyzing the work activities carried out by children in artisanal and small-scale mining in Katanga, DRC, in the wake of the evolution of representations of work, masculinity, family and childhood since the reforms of the Congolese mining sector promoted by the institutions of Bretton Woods. Katanga has been the industrial flagship of the Belgian Congo organized around the mining town of Lubumbashi during the colonial period and also after the independence of the country. The “union minière du Haut-Katanga” created by Belgians and nationalized after with the name of “Gécamines” has had a decisive impact on the structuration of the collective imagination on work, masculinity, family and childhood in this area of the country, which contains an infinite geologic potential and, as such, is strongly connected to global flows of raw materials exploitation. What is the impact of the reforms of the mining sector encouraged by the World Bank and the International Monetary Fund according to the ideals of schooling, nuclear family and father as the main breadwinner, the ones that have been promoted by the Gecamines during several decades? More specifically, what are the effects of these measures on socialization processes of youth and what are the consequences of those transformations on intergenerational dynamics? These questions that deal with the evolution of representations of childhood, work and family will be the main focus of our paper, which presents the results of a collective socio-anthropological research about child work in artisanal and small scale-mining in the Democratic Republic of Congo (Katanga province).

Practices of legal and bureaucratic categorisation, as well normative practices of naming are key within the endless construction and reinvention of nation-states. Such practices are part of larger and complex configurations of power along with institutions, more or less formal-informal practices of social control and governing. Today’s production and circulation of categories such “illegal migrant”, “refugee”, “young delinquent”, etc. need to be thought of in relation to categories such as “the national citizen” and the core values and principles attached to such categories. In this paper, I will explore how the dialectics of legality-illegality ─ and practices of visibilisation and invisibilisation ─ can be problematized in relation to a dual process: the ritual affirmation of the Party-state authority and the identity formation of rural migrant workers in South-China. I will argue that such politics ought to be read within the political economy of South-China or what Lee Ching-Kwan has called “decentralized legal authoritarianism” (Lee 2007). By looking at the production and circulation of the category of “the three no’s” (sanwu), I will show that the ambiguity and the flexibility of how this category is used is central in order to account for its symbolic and performative power.

In this presentation, we study the nonparametric regression model Y = m(X) +sigma(X) * epsilon where the error epsilon, with unknown distribution, is independent of the covariate X, and m(X) = E[Y|X] and sigma²(X) =Var[Y|X] are unknown smooth functions. The problem is to estimate the cumulative distribution function of the error in a nonparametric way when the couple (X;Y) is subject to generalized bias selection while the positive response Y can be right-censored. We propose a new estimator for the error distribution function. Asymptotic properties of the proposed estimator are established, namely the rate of convergence and the limiting distribution. A bootstrap procedure is developed to solve the critical problem of the smoothing parameter choice. The performance of the proposed estimator is investigated through simulations. Finally, a data set based on the mortality of diabetics is analyzed. [less ▲]

As early as the second half of the nineteenth century, some major European cities developed museums to present their history. This movement has grown around the world throughout the twentieth century. The phenomenon is now more relevant than ever, as evidenced by numerous projects of creation and renovation of such institutions. Nevertheless, it took a long time before this kind of museum began to be considered as part of a specific museum category, with its own characteristics and challenges. It was only in 1993, at the Museum of London, that representatives of museums devoted to the study of cities met for the very first time, in order “to discuss [their] problems, to develop theories and to promote [their] special place in the museum movement worldwide” (Hebditch, Max, Key-note address, in Johnson, Nichola, ed., Reflecting cities. The proceedings of a symposium. London, Museum of London, 1993, p. 1). The expression “city museum” took shape for this occasion, with the creation at the end of the symposium of what can be seen as the ancestor of CAMOC, the International Association of City Museums, which faded in 2005. For almost two decades, the city museum has become the object of study of a large number – almost one per year – of international conferences and collections of articles bringing together academics, but mostly professionals who live and experience the museum every day. Practitioners appear therefore as the main producers of discourse on the city museum. This presentation examines the concept of city museum through its different uses and definitions within the museological literature, between 1993 and 2008. The analysis of these speeches will highlight the fact that there are no unanimously established uses of the expression among the authors. It will also show that, as a museum category, city museum is an object whose identity is still under construction. [less ▲]

Dans un article de 2002, Jean and John Comarrof se penchent sur les « contradictions expérientielles » de ce qu’ils appellent un « capitalisme millénariste », c’est-à-dire « un capitalisme investi d’une force salvatrice » devant permettre la transformation des marginalisés et des subalternes » (Jean Comaroff and John Comaroff, « Alien-Nation : Zombies, Immigrants, and Millenial Capitalism », The South Atlantic Quarterly, n° 101, 4, Fall 2002). L’étude du fonctionnement du capitalisme flexible en Chine, avec son processus d’accumulation résultant de la combinaison de mécanismes institutionnels hérités du maoïsme et de mécanismes de marché, permet de se pencher sur les ruses du capitalisme, sur les redéploiements de modes complexes de gouvernement et de domination et sur les modes d’accommodement et de résistances des individus et groupes sociaux. Dans cette communication, j’explore des modes de domination qui, en parallèle avec la répression routinière et les régimes de production disciplinaires, agissent de façon complexe parce qu’ils sont basés sur des catégories d’émancipation et qu’ils travaillent au niveau des espoirs individuels de changement de condition, agissant au niveau des catégories de sens commun ou pratiques dans un contexte où le développement des forces productives et du marché constitue un champ idéologique intensément investi par les élites urbaines et l’Etat-parti. En me penchant sur les modalités de mise en récit et de luttes autour de la migration et du travail en ville─ mobilisations stratégiques, accommodements, renversements et chevauchements hégémoniques ─, j’entends montrer comment les expériences et récits des travailleurs migrants chinois s’articulent au sein d’un projet hégémonique de légitimation de l’ordre social et d’extraction de la plus value. Pour appréhender ce processus, je mobiliserai la notion de « cadre hégémonique » (Roseberry) entendu comme projet politique visant à établir un cadre matériel et discursif commun afin de cadrer et d’organiser la colère, la frustration mais aussi les espoirs, les aspirations et les désirs.

Les petites et moyennes entreprises (PME) constituent l’un des piliers de l’économie tunisienne où elles représentent 97 % du tissu économique. Bien que les études consacrées aux PME tunisiennes (Adair et al., 2009 ; Fhima et al., 2009 ; Djelassi et al. , 2010 ) sont assez nombreuses, rares sont les recherches scientifiques qui portent sur les spécificités des PME industrielles. Or, comme les autres entreprises, les PMI tunisiennes sont forcées de s’adapter aux mutations profondes qui caractérisent nos environnements et cette adaptation passe par une évolution constante de leur système d’information, notamment dans sa dimension comptable. Notre contribution se propose dès lors d’étudier théoriquement, au départ de l'analyse de la littérature développée en contexte tunisien, les spécificités des PMI tunisiennes et d’examiner l’impact des facteurs de contingence tels que la taille, le cycle de vie, la structure organisationnelle, l’incertitude de l’environnement, le secteur d’activité, le profil du dirigeant, l’âge et l’exportation sur le design du système d’information comptable.

Background Acknowledging individual and societal consequences of long term sickness absence, a political awareness is raising in Belgium in favour of a more active reintegration policy. Since various stakeholders are implied and several legislations may apply, it was deemed necessary to analyse the interplay between regulations and the role of the respective interveners to optimise return to work practices. The study focused on workers who are still under contract. Methods To this purpose, 23 representatives of various categories of stakeholders were interviewed: social insurance physicians, occupational physicians, insurers, social administration services, employers, unions, employment advisers, etc… Interviewees were asked to describe their role, to identify difficulties in the execution of their mission and sources of conflict between legislations, and to propose improvements. The interviews were audiotaped and fully transcribed. Results Several barriers to worker reintegration were pointed out during the interviews. On individual level, the worker social situation and a lack of information influence the chance of a successful return to work. At the enterprise level, the enterprise size, quality of peer support and lack of financial incentives were often mentioned. Most remarks concerned legislation. In Belgian labour law, the employment contract may be ended if the employee is permanently unable to perform his current job, even though modified work would remain possible. For many stakeholders, a sustainable return to work is hindered by the complexity of legislation which was developed for different domains (disability benefits, unemployment, work accident, occupational disease) with little attention to transitions from one domain to the other, especially between benefit insurance and unemployment legislation. It was also stressed that the possibilities offered by the occupational health legislation are underused or inappropriately used. Conclusions Legal and financial security must be insured for the worker who is ready to enrol in a reintegration trajectory. Public authorities should promote better knowledge and implementation of reintegration policies and current legislation should be improved with an emphasis on a better collaboration between stakeholders.

Aseptic and automatable vitrification of human embryonic stem cells using defined media Efficient recovery of biologically safe and undifferentiated hESCs is a major challenge after cryobanking, especially when their use for human therapy is foreseen. One drawback of actual cryopreservation protocols is the direct contact of the cells with liquid nitrogen, therefore cells can be in contact with heavy metals, bacteria, viruses or fungi during cooling and storage. We describe a novel cryopreservation method which uses aseptic vitrification1 (no direct contact with LN2) and only chemically defined materials and media, and is automatable. 1: Vitrification is a cryopreservation method based on the conversion of a liquid into a glass-like state by an infinite enhancement of its viscosity and without formation of ice crystals.

Updated information on the most common infectious diseases that the mother may transmit to her infant during pregnancy, at birth or by breast feeding the infant. Most of the emphasis is directed to preventive measures, screening when interventions are available, and the detailed analysis of interventions during the preconceptional period, antenatal care, perinatal care and maternal and neonatal care after birth. The strategic approach for prevention is illustrated with the group B streptococci story. This information emphasizes the basic knowledge of the pathogen, the disease, the burden of problems caused by the disease in the mother and her offspring, epidemiological aspects, and how to manage the disease. Most of the emphasis is directed to screening-based preventive measures and new approaches to improve the accuracy and predictive values of screening are discussed. An update of the developments of a group B streptococcal vaccine is briefly presented. [less ▲]

Background: Coordination between levels of care is not compulsory in the Belgian health system. Patients have direct access to specialists. Hence, competition between professionals and fragmentation of care do occur, leading to poor quality of care and waste of resources. A strategy that improves communication and coordination between actors and stakeholders at a local scale represents a solution to develop integrative care oriented to people and community. The Local Health System (LHS), launched 15 years ago with some success in specific settings in Belgium, is the model used for this experience. What could be the opportunities and threats to improve coordination between levels of care in various local contexts? [less ▲]

Background: Unjustified modifications of the patient’s usual medication during his hospitalisation induce various problems for the patient (confusion, additional costs) and for healthcare professionals (work overload, additional cost). The principle of favouring dialogue between local actors to reach commonly accepted solutions (KCE, 2010) was used in the current study. Research question: Which local strategies could be implemented to improve continuity of drug therapy when the patient moves to hospital or back home? Method: The study took place in Liège (Wallonia). Participants were recruited within four professional groups: general practitioners, hospital specialists, pharmacists and hospital stakeholders. First, a nominal group was carried out for each professional group. Prioritized suggestions were obtained. In a second phase, Delphi method was used. Suggestions from the nominal group were submitted to representatives of each profession (a total of 40) to evaluate relevance, acceptability and feasibility of each one. Results: A total of 101 suggestions were evoked in the first phase. They were related to two main themes: implication of well-defined actors and development of specific means. Five consensual suggestions emerged from the Delphi process: provision by the general practitioner of a complete list of medication on hospital admission; provision by the hospital specialist of a list of drugs at discharge; development of formal hospital processes to keep the patient’s usual medication; centralisation of medication data; development and use of a unique medical record. Conclusion: A link medium handled by the patient when he moves to the hospital and back home is the major idea mentioned and accepted by local actors. [less ▲]

Sport pedagogy is a discipline aimed at providing scientific data on the education and training in the different contexts in the field of sport and physical activity: education, coaching, recreation, rehabilitation … Using traditionally descriptive, correlational and experimental approaches, it is focused as much on the main actors (participants and educators) than on contents or on curricula. Its main objectives consist to improve the knowledge and the field practice of the physical educators and their trainers. Most studies in sport pedagogy are conducted in the school context as physical education remains a central concern of researchers. Nevertheless, since two decades, the place of the science of coaching grows slowly while researches in leisure and rehabilitation are still quite rare. In parallel, physical activity and the fight against one sedentary lifestyle became really important in the preoccupations of most of the researchers. Moreover, two important concepts are developing nowadays: accountability and literacy. This underlines that physical educators are expected to meet the goals that modern society emphasizes: efficiency and effectiveness. Quality is now regularly identified as a priority or even a prerequisite. Current researches in sport pedagogy is become complex as they mobilize more and more often complementary approaches taking into account all the involved actors and environment. Moreover, subjects became central with the development of action researches and communities of practices. [less ▲]

Metagenomics has appeared as a powerful tool to study bacterial composition of various environmental samples. This work describes the application of this technique to study the bacterial population of two fresh fish filets. The two fish species are from freshwater (pangasius) and seawater (haddock), respectively. Samples where directly analyzed the day of receipt. Others samples were analyzed at the end their shelf life after storage at 4°C (1/3 of their shelf life) and 8°C (2/3 of their shelf life). For these samples, packagings were made in plastic wrap for atmospheric air condition and in trays under modified atmosphere. Classical microbiological and 16S rDNA metagenomic analysis were carried out on all these samples. The composition and evolution of microbial populations of fish filet stored under different packaging conditions and temperatures of storage were investigated with identification of bacteria species. A total of 40 different species were identified for both fish types. Gram-negative bacteria are always predominated among the initial flora and at the end of the shelf life in all the trials. At the beginning of storage, the predominant Gram-negative microflora consisted of Moraxellaceae (Acinetobacter spp, Psychrobacter spp.), Pseudomonadaceae (Pseudomonas spp), and Shewanella spp and the Gram-positive flora was identified as Lactobacillaceae (Carnobacterium spp), Brochothrix thermosphacta and Planococcus donghaensis (only for pangasius). For the pangasius, Planococcus donghaensis is only present before the fish is packed and its dominant presence could provide an indication of the freshness of the fish. The metagenomic analysis is a useful tool to identify and to measure the relative proportions of bacterial species in fish filet samples. [less ▲]

MSC cells have demonstrated significant immunosuppressive effects in various in vivo and in vitro studies. This study aims to be the first evaluation of the safety and tolerability of third party MSC infusion after cadaveric kidney and liver transplantation in a prospective phase I-II study, taking advantage of our centre expertise and experience in MSC use in graft-versus-host disease (GVHD) after bone marrow transplantation and using an already functioning GMP-compliant laboratory producing clinical-grade MSC. Secondary end-points will help to evaluate the immunosuppressive potential of MSC after organ transplantation, and the opportunity to develop larger randomised, controlled, phase III trials. After successful transplantation, 10 liver and 10 kidney transplant recipients under standard immunosuppression (tacrolimus, MMF, steroids) will receive an intravenous infusion of 1.5-3x106/kg of third-party MSC on post-operative day 3±2. These patients will be prospectively compared to 10 liver and 10 kidney recipients who meet the inclusion criteria but deny MSC infusion. Safety will be assessed by recording side effects, including opportunistic infections and cancers. Immunosuppressive potential will be evaluated by rejection episode rates, by graft/patient survivals, by immunohistology of 3-months kidney and 6-month liver graft biopsies and by in vitro evaluation of the immunity profile of the recipients. In a second step, reduction (kidney) and progressive weaning (liver) of immunosuppression will be attempted in recipients who received MSC. This ongoing study is supported by research grants from the CHU of Liège, University of Liège, and by the Senior Clinical Research Grant from ESOT. The first patients were included and treated in early 2012, and final results expected in late 2013. [less ▲]

Aims: To evaluate the prognosis of horses treated surgically for open joint injuries. Methods: The medical records of horses admitted for surgical treatment of a wound in communication with a joint were reviewed. A telephone questionnaire was used for the long term evaluation. Fisher’s exact tests were used for the statistical analyses. Results: Twenty two horses were included in the study with the following distribution of lesions: 6 carpi, 6 fetlocks, 4 tibiotarsal joints, 2 proximal and 3 distal interphalangeal joints, 1 elbow. The duration of the injury before referral ranged from 3 hours to 10 days. Surgical treatment consisted of 1-3 joint lavages. Of the 22 horses, 4 were euthanatized during hospitalization and 18 were discharged. After discharge, 3 horses died due to colic, 2 were lost and 13 were still alive. The survival was not influenced by the duration of the wound. All horses with cutaneous defects less than 5 cm and all horses affected in the lower limb (below the level of the canon) were discharged. Having an affected joint proximal to the canon was significantly associated to the need of multiple surgeries (OR: 17.5; p= 0.024). Conclusions: Even if the prognosis remains guarded for open joint injuries, a long delay between injury and treatment should not be systematically associated with a bad prognosis for survival. Open joint injuries of the lower limb were associated with survival. They required less often multiple articular lavages than open joint injuries of the upper limb, warranting thus a better prognosis. [less ▲]
