In Europe, as in North America, GBS infections among infants are associated to high morbidity and mortality even if some differences exist between different European countries. During the past two decades, major initiatives have been proposed to prevent early onset GBS disease (EOD) and they are still subject of controversy. Several European countries have issued guidelines for the prevention of neonatal GBS diseases, either universal screening-based or risk-based strategy, others have no official guidelines at all. In countries having guidelines, despite considerable efforts and economic resources spent on intrapartum antimicrobial prophylaxis for GBS EOD, cases continue to occur. Among these cases there are a lot of missed opportunities to administer IAP but there are also false negative screening. Therefore in the setting of a maternal GBS-screening program and successful implementation of the strategy, efforts to improve screening for GBS status remain important. The natural reservoir for GBS is the gastrointestinal tract and is likely the source for vaginal colonization. Among pregnant women, GBS carriage rate in the vaginal and rectal flora ranges from 10% up to 30%. Critical factors that influence the accuracy of detecting GBS maternal colonization are the choice of the body sites sampled, the timing of sampling and the use of selective culture media. The evolution of the different culture options to improve the GBS-screening strategy will be reviewed. If the optimal time for performing antenatal cultures is between 35 to 37 weeks’ gestation, as GBS carriage is highly variable, the predictive values of GBS antenatal cultures are not always as good predictors of the maternal GBS status at presentation for delivery as expected. Potential alternative to antenatal GBS-screening culture is the identification of GBS colonization at presentation for delivery. Use of a reliable, sensitive, easy to use rapid test should be cost effective leading to the prevention of more EOGBS cases while reducing the number of unnecessarily IAP. Advances of polymerase chain reaction (PCR) and fluorescence labeling technologies has provided new detection tools for bacterial identification. Therefore, commercialization of rapid detection of GBS through real-time PCR offers the potential for GBS detection among women without prenatal care or those in whom no antenatal culture was collected. However questions of costs and logistics remain unanswered. Could such rapid intrapartum test replace existing screening strategies or could it be used in conjunction with them? Colonizing rates and recommended screening procedures existing through Europe will be reviewed. [less ▲]

Le psychothérapeute (psychologue ou psychiatre) peut être convoqué comme témoin lors d’un procès concernant un de ses patients ou clients. Dans ce cadre, la Loi prévoit une exception à l’obligation du secret professionnel et autorise le professionnel à dévoiler des éléments liés à la psychothérapie. Cependant, si la Loi autorise la levée du secret professionnel, l’éthique et la déontologie professionnelles ne recommandent pas nécessairement de suivre cette voie. En effet, de nombreuses questions, telles que l’utilité, les risques et les conséquences de cette divulgation, se posent aussi bien au niveau de la relation thérapeutique avec la personne concernée que pour l’ensemble de la profession et le cadre thérapeutique de la pratique clinique de manière générale. Cette communication présente une réflexion autour des divergences qui apparaissent entre ce que préconisent la Loi, l’éthique et la déontologie. En outre, nous proposons d’alimenter la discussion en distinguant les situations dans lesquelles le patient ou client du psychothérapeute est la victime ou au contraire, l’auteur de faits délictueux.

Introduction and Background: Carbohydrate-based surfactants (CBS) are, today, among the most attractive amphiphilic compounds owing to their high potentiality for a large product concept. The main fundamental reasons are the abundance of their precursors from renewable resources, the excellent environmental compatibility, and the quasi-unlimited availability of their molecular structure and geometry. Based on the latter aspect, CBS would be expected to generate a wide range of functionalities and activities for food and non-food applications. All kinds of amphiphilic compounds including small surfactants, bolaforms, geminis, oligomeric, and polymeric molecules with a single or a multiple hydrophobic tails can be designed by synthetic routes thanks to a large number of reactive chemical groups in their basic structure. Consequently, various methodologies are required, and could be used in complementary for identifying all of their potentiality for further development. Methodology: The methodology is based on the characterization in the laboratory scale, i.e. using only small amounts of sample, of CBS properties at fluid and solid interfaces, in bulk liquid phases, and at the solid state with simplified models. Results and Discussion: In this communication, an overview of functionality and activity-predicting methods for a wide range of CBS structures varying in head polar groups, hydrophobic tail and number, and linkers will be presented and discussed. Performances and complementarities of different approaches, methodologies, and techniques will be emphasized. These include sample preparation and analysis procedures, interfacial-characterizing instruments, mainly tensiometers and Langmuir balances used both in dynamic and (quasi)-static modes, particle size and electrical charge analyser, and (micro)calorimeters using differential scanning, isothermal titration, and thermogravimetry methods. Conclusion: The knowledge of these basic properties is helpful for predicting their main activities and functionalities like their aptitude for forming and stabilizing colloidal systems, and for developing biological activities. This is also necessary for the rational design of CBS amphiphilic structure regarding to specific properties. The same approach can also be applied for other required features as the compound stability, toxicity, and biodegradability. [less ▲]

Notre rapport aux images peut-il être aussi réfléchi et critique que notre rapport aux discours (au langage) ? Et si l’on suppose que oui, comment le définir ? Cette question est d’une grande actualité : l’iconosphère contemporaine est tellement riche (au double sens d’abondante et de difficile à digérer/assimiler), qu’il importe de se ménager la possibilité d’un point de vue critique sur les images. Warburg – pour sa part – formulait le problème comme suit : comment s’orienter dans l’espace de pensée ouvert par les images ? À cette question d'orientation répond le projet d’un Atlas d’images intitulé Mnemosyne. Je vais donc ici tourner autour de l’œuvre tardive de Warburg (années 20) pour essayer de saisir au mieux l’usage qu’il fait du concept de Denkraum (espace de pensée). Il y a un lien étroit entre les recherches de Warburg sur le Denkraum et le projet Mnemosyne. Pour le dire plus franchement encore : l’Atlas de Warburg nous présente visuellement le Denkraum. Le projet de l’Atlas tend vers une explicitation de l’espace de pensée renaissant et, à partir de là sans doute, de l’espace de pensée contemporain. Warburg dit lui même que l’idée qui guide la confection de l’Atlas consiste à retrouver l’origine de l’espace de pensée [Der Ursprung des Denkraums] . [less ▲]

This paper aims at studying the effect of the extent of disclosure on information asymmetry and stock-market liquidity in France. Our sample includes196 French listed firms over a period ranging from 2004 to 2007, the results show that the extent of disclosure in annual reports positively influence the liquidity of the French market. This is explained by the negative effect of the disclosure on the adverse selection component of the bid-ask spread. This effect is further confirmed by the commitment to IFRS by French-listed firms from 2005. This result should encourage French authorities to further improve their information environment as essential to reduce the costs of asymetric information and prevent the risk of illiquidity.

This paper presents first results of a study that examines the impact of the workplace climate on workplace training effectiveness. Here training effectiveness is conceptualised in terms of transfer of training and the workplace climate is specified in terms of transfer climate. According to the theoretical framework by Carr, Schmidt, Ford and DeShon (2003), we hypothesise that the impact of the transfer climate on the transfer of training will be moderated and/or mediated by cognitive and affective states. Statistical analyses will be conducted to check the hypothesised mediating and moderating role of job satisfaction (affective state) and job engagement (cognitive state) between the transfer climate and the transfer of the newly acquired knowledge. Transfer climate has been broadly studied for its direct impact on transfer of training. The major issue of this study is to examine the interaction of the transfer climate with other variables In a longitudinal quantitative study, data are collected at the Belgian Sickness Fund. Participants are employees who took part to a training session between March and December 2010 (N=680). Right after the conclusion of the training program, each trainee is invited to fill the Learning transfer System Inventory (Holton, Bates, & Ruona, 2000), a scale measuring 16 dimensions of the transfer climate. One month later, participants are asked to fill a second questionnaire about their perception of the transfer (general and specific performance), job satisfaction (Price, 1977) and job engagement (Schaufeli & Bakker, 2003).

Mind-wandering refers to the occurrence of thoughts whose content is both decoupled from stimuli present in the immediate environment and unrelated to the task currently being carried out. In a series of experiments, we used a newly designed experience sampling method to assess mind-wandering episodes and to distinguish them from other kinds of distractions (irrelevant interoceptive/exteroceptive sensory perceptions and interfering thoughts related to the appraisal of the current task). In Experiment 1, we examined the impact of mind-wandering on performance of the Sustained Attention to Response Task (SART; a Go/No-Go task). Analyses demonstrated that episodes of mind-wandering impair SART performance to the same extent as irrelevant sensory perceptions. In Experiment 2, we focused on the content of mind-wandering in order to assess its possible functions. We observed that most of reported mind-wandering episodes refer to the anticipation and planning of future events. Furthermore, this “prospective bias” was increased when participants’ attention had been oriented toward their personal goals prior to performing the SART. In Experiment 3, we examined the neural correlates of mind-wandering using functional magnetic resonance imaging. The results showed that the brain regions that were more active during episodes of mind-wandering are similar to the regions that have been associated with imagining future events in previous studies. Together, these results suggest that although episodes of mind-wandering negatively impact current task performance, they may have important adaptive value and could, in particular, play a key role in planning for the future.

Le décret des missions prioritaires de l’enseignement fondamental et secondaire, les programmes du secondaire supérieur en sciences et les commissions des outils d’évaluation recommandent de travailler la compétence « expérimenter – utiliser des procédures expérimentales » avec les élèves (FT2 mener à bien une recherche expérimentale). Les futurs enseignants du secondaire supérieur ne sont pas toujours conscients des enjeux et de la portée des démarches scientifiques (et/ou expérimentales) qu’ils mettent en place en classe. Regarder un « C’est pas sorcier », cela équivaut-il à réaliser ou faire réaliser aux élèves une expérience en classe ? Certains ont peur de se lancer dans des démarches expérimentales plus libres car ils craignent la question dont ils n’auraient pas réponse immédiate ou la piste expérimentale qu’ils n’auraient pas anticipée. D’autres craignent l’expérience qui rate, la saleté, le désordre et le bruit. D’autres encore mentionnent le matériel, difficile à rassembler et surtout à transporter, le temps nécessaire pour mener à bien certaines expériences (p.ex. germinations)… Sous l’intitulé « expérimentons », les manuels scolaires proposent différents types d’outils. Est-ce que ces démarches correspondent réellement à cette compétence ? Est-ce l’élève qui expérimente ? Quel est l’apport de ce type d’outils ? En proposant différents ateliers « expérimentaux » aux participants, nous voudrions attirer l’attention sur ces différents points et réfléchir ensemble à ces questions :  Quel est le statut réel de la démarche proposée aux élèves ?  Quelle est la part de l’élève dans la construction de son apprentissage? Quel est le rôle de l’enseignant ?  Quels sont les avantages à travailler par ce type de démarches pour l’enseignant et pour ses élèves? Quelle image de la science et du scientifique véhicule-t-on à travers notre façon de travailler la compétence « expérimenter » en classe ?

The Belgian emigrants’ political participation in home country politics is an issue that has undergone several important developments since the end of the 1990s but has surprisingly been subject to very little research. The absence of the issue of emigration from the Belgian political agenda combined with the limited engagement of this population with the home country thus stands for the absence of research on the topic. The lack of academic interest, in turn, has favoured the development of two major stereotypes in Belgium with respect to the political preferences of citizens residing abroad. One is that the Belgian population abroad would tend to be more favourable to right-wing parties than the average Belgian citizens. This stereotype has long explained why the Francophone liberal party (PRL later called MR) has been most active in supporting the enfranchisement of citizens abroad for legislative elections. The second stereotype, to which we will devote most of our attention in this article, supposes that Belgians abroad would be unaffected by the political tensions opposing Flemish and Francophone political parties in Belgium over the past decade. Despite the fact that over the past forty years Belgian politics have been increasingly dominated by the ethnic tension between Flemings and Francophones, the stereotype that Belgians abroad would be unaffected by these developments has remained. The idea that the evolution towards greater regional autonomy defended by political parties (with more intensity in Flanders than in French-speaking Belgium) would not find echo among Belgians abroad is thus very prevalent and is still frequently propagated by the press. In this article, I however question this idea that the political opinions of Belgians abroad would be unaffected by the evolution of the ethnic conflict between Flemings and Francophones and argue instead that the evolution of the ethnic conflict has led to the parallel division of the Belgian political opinion abroad. Belgian emigrants are not more supportive of the Belgian unitary state model than Belgian citizens residing in Belgium. To support this argument, I will proceed to the following analysis. After a brief presentation of the socio-demographic profile of the Belgian emigrant population, I first proceed to a discussion on the creation of the two main Belgian emigrant associations to demonstrate how the tension between Flemings and Francophones was a crucial variable in the creation and development of these organizations. Second, I discuss the adoption of the two external voting laws to illustrate how the anticipated impact of emigrant voters has steered controversies on the territorial border between Flemish and French-speaking areas of Belgium. This situation, I argue, has contributed to further the distinction between Flemish and French-speaking Belgians abroad. Third, comparing the evolution of national legislative elections in 2003, 2007 and 2010, I argue that the success of Flemish nationalist parties in Flanders has followed a similar pattern among Flemish voters abroad.

Nowadays, analysis of bibliographic databases is a current practice, especially the comparison between traditional, commercial databases and search engines as Google Scholar that has wind right aft. A great deal of researchers analyzed the contents or the citations system of various databases. Some compared the contents of several databases, for specific scientific domains, searching by author (Mikki, 2010; Cecchino, 2010) or keywords (Falagas, 2008). There are no studies concerning the precise domain of geography. This study covers bibliographical databases specialized in geography (physical and human) and Google Scholar search engine. This analyze will point out to geographers what a research in Google Scholar search engine can offer, regarding exclusively contents, in comparison with traditional databases: WOS, Francis and Georef. This analysis does not aim to underline the difference of databases features, but to show what a research in certain databases can bring, from the point of view of contents. To perform this study, we use keywords (in English) and establish them for the physical and human geography according to actual subjects of the respective fields. The research will bring new concrete results given that no comparison of this type was led between the traditional databases used by geographers and Google Scholar. We also hope to give an idea of the possible evolution of the contents for Google Scholar search engine during the determined period of our study. [less ▲]

Several satellites measure Sea Surface Temperature (SST), each of these with different technical specificities and error sources. Together with in situ data, they form a highly complementary data set. The creation of merged SST products, integrating the strengths of each of its components and minimising their weaknesses, is however not an easy task, but it is certainly a desirable goal that has generated a large amount of research over the last years. The main objectives of this project are, among others: 1.To develop a technology, based on DINEOF (Data Interpolating Empirical Orthogonal Functions), that allows to merge different data sets at very different sampling intervals (in space and time) and create an integrated product at the highest sampling frequency and with the highest quality possible. 2.To provide improved, merged analyses of variables such as SST and chlorophyll. 3.Obtain a better understanding of the diurnal cycle of the studied variables. 4.To better understand the relation between variables (and take advantage of these relationship to improve the analyses). 5.Using the above-mentioned developments, explore the capability of the developed technology to produce SST forecasts based on multi-variate EOFs and model forecasts. We will present the first preliminary results for merging different SST data sets, as well as our plans for future developments and applications.

The aphid Aphis gossypii Glover (Homoptera: Aphididae) is known as worldwide important pest. It causes serious injuries to crops, but is also able to feed on various cultivated and wild plants. Some programs are developped to control this aphid. In many studies , hoverfy Episyrphus balteatus De Geer (Diptera : Syrphidae) is used as an efficient and aphid specific predator in biological control systems. In this work, we study cotton aphid choice plant discrimination, the effect of host plants on its developpment(fecondity and mortality), and the E.balteatus foraging and oviposition behavior according aphid host plants. Biologic parameters were observed using various plant combinations. E.balteatus behavioral observations were conducted using the Noldus Observer v.5.0. A.gossypii makes discriminant choice of his hosts, with better preference on Cucurbita pepo L. (Cucurbitaceae) and Capsicum annuum L. (Solanaceae). Dacryodes edulis (G. Don) H.J. Lam. (Burseraceae) and Vicia faba L. (Fabaceae) are the midle choice while Hibiscus sabdariffa L. (Malvaceae) is less chosen. A.gossypii develops easily on C.pepo, and weakly on C.anuum, H.sabdariffa,and V.faba. D. edulis induces very high mortality to A.gossypii. According to E. balteatus behavior, A. gossypii is more attractive when infesting C .pepo and V.faba, less on H. sabdariffa. While non infested , the hoverfly more attractive plant is V.faba. Our results highlited the importance of interactions between aphids and their host plants and the prey-host influence on a specific aphid predatory hoverfy. Suitable ways in correlation with this work are to investigated to complete this study and perform aphids biological control. [less ▲]

Postharvest fungal pathogens, mainly Botrytis cinerea, Penicillum expansum and Gloeosporium spp., annually cause 5-20% losses of fruit. Control measures against these diseases include chemical fungicide applications, but the development of resistant fungal explains the growing interest for biological control. Pichia anomala strain K was previously identified as an efficient antagonist of pathogens on apples. Indeed, the percentage of protection of P.anomala against B.cinerea reached from 90 to 100% on apple wounds according to the experimental conditions. Microbiological, biochemical and molecular approaches demonstrated the implication of exo-β-1,3-glucanases in the mechanism of action of P.anomala. However, study of these mechanisms could be improved by observations under natural infection conditions in order to take into account the tripartite interactions host/antagonist/pathogen. The proteomic tool allowed an overview of process implicated in the antagonism against B.cinerea in such conditions. One 50mm wound per apple were covered by a membrane and inoculated by a P.anomala suspension then by B.cinerea or not. Samples were collected during the exponential and stationary phase to identify the early and later responses to the presence of B.cinerea. After extraction, proteins were separated on 2DE gels. Spots influenced by the presence of B.cinerea in exponential and stationary phases were identified by MALDI-ToF. One hundred five and sixty spots of proteins were influenced by the presence of B.cinerea in exponential and stationary phase respectively. In exponential phase, influenced proteins were implicated in the different steps of the proteins biosynthesis: amino acid synthesis, translation or mRNA maturation and in energy synthesis. On the other hand, in stationary phase, influenced proteins were mainly implicated in energy metabolic pathway: glycolysis, alcoholic fermentation or gluconeogenesis. The presence of B.cinerea seemed to induce a slowdown in the metabolism of P.anomala without influenced its growth. Further studies have to be realized to understand the complexity of these modes of action. [less ▲]

Wireworms, the belowground larvae of click beetles (Coleoptera: Elateridae), represent a threat for various crops, including cereals, potatoes and small fruits, in many countries. In order to promote the development of bio-pesticides or the selection of resistant varieties, studies concerning the close relationship between wireworms and the roots they attack have to be conducted. Indeed, lacks of knowledge in the chemical ecology of these small but consequent pests baffle such achievements. Here, we studied the reactions of wireworms (Agriotes sordidus Illiger) facing root-emitted volatile organic compounds (VOCs) of barley. We first tested the ability of wireworms to orientate towards a blend of volatile compounds emitted by seven day’s old mashed roots of barley grown in vermiculite. We used a Y-shaped horizontal olfactometre, which inferior half was filled with compressed and humidified vermiculite. Wireworms were able to detect blends of volatiles emitted by mashed roots, and to orientate their foraging behaviour toward the emission source. Volatile compounds were identified from barley roots using SPME-GC-MS and several chemicals were identified. This study is part of a larger programme which purpose is the identification of VOCs emitted by the roots of barley and different actors of the rhizosphere, and to assess their semiochemical functions.

The Phase Response Curve (PRC) has proven a useful tool for the reduction of complex oscillator models to one-dimensional phase models. We introduce the sensitivity analysis of this important mathematical object and its numerical implementation. As an application, we study simple biochemical models of circadian oscillators and discuss how sensitivity analysis helps drawing connections between the state-space model of the oscillator and its phase response curve.

Introduction From April 2011, the function of dialogue will receive a structural financial support for the mental health care in Belgium. This function will be partly built on the experience of the therapeutic projects “care networks”. This research work takes shape with the organisation of multidisciplinary meetings and dialogues around chronic and complex situations. Especially, the therapeutic project n°79 “disruptive children and adolescents behaviours from moderate to severe intensity” tends to provide tailor-made care and a better follow-up to these patients while maximizing complementarities between partners and avoiding as much as possible redundancy in care, help, support and supervision. Purpose To provide recommendations on the organization of consultation meetings and intersectorial collaboration. Methodology The therapeutic project n° 79 is aimed at children and adolescents aged 0 to 21, living in the province of Liège and showing a specific psychiatric pathology: conduct disorder, oppositional defiant disorder, attention deficit/hyperactivity disorder. This project is based on an empirical approach. It consists in organising multidisciplinary meetings and dialogues concerning patients and their families, with the aim of a individualized follow-up. The device used in these meetings is the care plan. It allows structure the debates considering a general goal for the child and the specific aims of the different services. This personalized care plan provides network coordination to the child and his family and avoids any situation of mutual returns. It also increases the visibility of each other’s role within the care plan. Moreover, it results in the definition of a schedule and evaluation periods. Results The project has followed 59 users, 44% of whom were adolescents above the age of 12. In each situation, an agent has been chosen to follow the case. His role is to keep in touch with the user and to be the contact person with the different professionals. He is in charge of the organisation and the management of the meetings. The agent can come from any sector. Recommendations on this topic have been reported. Discussion/conclusion The experience of the therapeutic project n° 79 turned out to be highly fruitful. All the purposes focusing on the user and his family were achieved and there were also many positive interprofessional relationships and collaborative work. Multidisciplinary consultation meetings turned out to be an effective way to get to know partners and it gives a clear view of their respective services and care offers as well as their functioning. The method applied in our project appeared to facilitate collaborative working and coordination between professionals from various areas acting in the users’ own interests. [less ▲]

In October-November 2010, more than 5000 Belgian students from both side of the linguistic border have been asked to “draw Belgium” – no other guidelines were given. In addition to this rather unusual question, the students were surveyed on their political interest, political knowledge, identities, political perceptions and preferences as well as their attitudes towards Belgium and her future. In a time when Belgium is stuck in a quite deep institutional crisis, this innovative research yields original data on the political visions held by a generation that always lived under federalism and that might soon decide upon the future of the country. The results for this sample can also be compared to samples drawn from the whole population and therefore offer much insight about how young Belgians differ – or not – from previous generations. Moreover, such a design allows for comparisons within and between the two main linguistic communities; this is likely to offer a much more diverse portrait than the too-common picture of two monolithic blocks at war with each other along linguistic lines. Above all, with this research we can indirectly explore the processes – of socialization – behind the formation of political preferences and more specifically how socio-demographics, political knowledge, political interest, voting behaviour interact with the students’ representations and attitudes vis-à-vis their country and its future.

La question du vivre ensemble se situe au cœur de toute société multinationale ; plus précisément, elle définit la nature des relations entre les « communautés » nationales qui composent cette société et anime sa dynamique politique. Avec deux grandes communautés nationales, le Canada et la Belgique connaissent régulièrement l’acuité de cette question fondamentale. Dans ces deux fédérations, les différences linguistiques entre l’anglais et le français, d’une part, et le néerlandais et le français, d’autre part, posent naturellement des problèmes à la fois philosophiques, linguistiques et politiques. Surtout ces différences – en termes d’expressions – renvoient à des représentations différentes du vivre ensemble. Cette proposition vise à explorer ces différences d’expressions et de représentations en étudiant quatre corpus de données recueillis au Québec (Montréal), en Ontario (Kingston), en Belgique francophone (Liège) et en Belgique néerlandophone (Anvers) lors de quatre panels citoyens qui ont rassemblés pendant plusieurs heures une vingtaine de citoyens locaux. Ces données permettent non seulement des comparaisons au sein de chaque terrain mais également entre les terrains. C’est donc de véritables regards croisés qui peuvent venir éclairer la question du vivre ensemble au Canada et en Belgique. Il ressort de cette lecture comparative, mêlant science politique et linguistique, que si les mots et les expressions importent dans une réflexion politique sur le vivre ensemble, il convient de relier ceux-ci aux représentations, voire aux métaphores, sous-jacentes qui les animent. Se pose alors la question de savoir si les différences linguistiques et politiques entre les deux grandes communautés nationales de chaque pays sont rédhibitoires ou non, et surtout ce que cela implique pour l’organisation du vivre ensemble.

The TCLUST procedure is a new robust clustering method introduced by García-Escudero et al. (2008). It performs clustering with the aim of finding clusters with different scatters and weights. As the corresponding objective function can be unbounded, a restriction is added on the eigenvalues-ratio of the scatter matrices. The robustness of the method is guaranteed by allowing the trimming of a given proportion of observations. This trimming level has to be chosen by the practitioner, as well as the number of clusters. Suitable values for these parameters can be obtained throughout the careful examination of some classification trimmed likelihood curves (García-Escudero et al., 2010). The first part of this talk will consist of a brief presentation of this clustering procedure and the related R package (tclust). In the second part of the talk, the robustness of the TCLUST procedure, and more precisely its breakdown behavior, will be studied. In the context of cluster analysis, Hennig (2004, 2008) has defined some useful concepts to characterize the breakdown of a procedure; the r-components breakdown point, the dissolution point and the isolation robustness. These tools will be applied to the TCLUST procedure and some examples will be presented. [less ▲]

This paper examines the potential of economies of scale and scope among the African central securities depository institutions. We address whether the consolidation of settlement and custody activities of securities make these institutions efficient in light of the costs of service parameter. To do this, we rely on the translog cost function [introduced by Christensen et al. (1971)] and the constant elasticity of substitution of seven central securities depositories in Africa over the period 2004-2009. The results show the existence of significant economies of scale and scope in these institutions. The extent of these economies differs upon the size of the institution and the level of automation mechanisms to combine securities settlement and custody activities. Our findings also indicate that, unlike large institutions in countries such as South Africa and Mauritius, which have heavily invested in automation mechanisms, smaller institutions have higher service costs, which implies a need for consolidation of activities to reduce these costs.

The effects of reproduction and maternal investment (i.e. milk transfer) on trace element levels remain poorly understood in marine mammals. We examined the blood dynamics of Cd, Pb, Hg, Cr, Ni, V, Zn, Cu, Fe, Ca and Se throughout lactation in a top predator from the North Sea, the grey seal (Halichoerus grypus). Trace element levels were measured in blood and milk of 21 mother-pup pairs in early and late lactation. Maternal hair and natal fur (lanugo) were also collected and analyzed. Trace element levels in blood decreased according to the following pattern: Fe > Ca > Zn > Se > Cu > Hg > Pb > Cr > V in mothers and pups. Cd and Ni were not detected in blood. The substantial levels measured in lanugo indicate nevertheless that all trace elements (including Cd and Ni) were transferred to offspring through the placenta. In maternal hair, Pb levels (~ 2.2 mg/kg dw) were relatively high in comparison with other phocid species. All trace elements, except Cd, were detected in the milk showing a transmammary transfer to offspring, especially for elements such as Ca, Se, V, Ni and Pb. Hg showed the highest levels in blood (up to 0.25 mg/kg ww) and hair (up to 21 mg/kg dw) from the non-essential and toxic metals measured. Levels of Hg and essential elements (Ca, Fe, Zn, Cu and Se) in blood and milk showed significant variations throughout the lactation period. Therefore, physiological processes such as lactation affect trace element levels in tissues of mother and pup elephant seals. Such processes and its relationship to body condition should be considered carefully when interpreting trace element levels in the framework of biomonitoring. [less ▲]

Since 1960, both Canada and Belgium have experienced passionate debates about the future of federalism in their country. While the debate has somewhat declined in Canada in general and in Quebec in particular, it is currently very hot in Belgium. However, both federations share a common goal – accommodating within a single country two national communities – which enables a fruitful comparison of the way one can think Canada with or without Quebec and Belgium with or without Flanders. More specifically it is interesting to look comparatively at the place of Quebec and of Flanders in their respective federation. It can be done through the eyes of Quebeckers and Flemish but also through the eyes of citizens from the other community: English-speaking Canadians and French-speaking Belgians. Relying on qualitative date collected in Quebec, Ontario, Flanders and Wallonia, this paper aims at illuminating the identity and the federal dynamics in Canada and Belgium from below – the citizens – rather than from the top – institutions or political actors. While institutions and political actors do matter, citizens play also an important role in thinking their country and the place of their region within or without it. [less ▲]

Methylmercury (MeHg) and selenium (Se) can be found at elevated concentrations in blood of marine mammals and both display modulatory effects on the immune system. Whereas mercury (Hg)-Se antagonism in liver of marine mammals is well known, the protective role of Se against Hg immunotoxicity in marine mammals has been poorly described. We propose here an in vitro approach using combined Hg and Se in vitro exposure of peripheral blood mononuclear cells (PBMCs) of the harbor seal (Phoca vitulina). PBMCs were isolated from the blood of 10 harbor seals and exposed to environmental concentrations of MeHg (1µM) and selenite or selenomethionine (5µM), respectively inorganic and organic forms of Se. MeHg leaded to a decrease of lymphocyte proliferation, to an increase of cells with compromised mitochondrial membrane potentials and cell death. Preliminary results evidenced that none of the two Se forms had a protective effect against MeHg toxicity, although cells were slightly stimulated by Se alone. Therefore MeHg expresses its toxicity among blood circulating lymphocytes in presence or absence of selenite or selenomethionine. [less ▲]

Elle est aussi souvent prescrite au stade de l'intolérance au glucose ou dans l'hyperinsulinisme avec hypoglycémies réactionnelles. La metformine a obtenu ses lettres de noblesse dans le cadre de troubles de la glycémie. Elle expose à certains inconforts abdominaux fréquents et proportionnels à la dose. Une complication rare mais très dangereuse sur le plan vital est l'acidose lactique due le plus souvent à l'usage de la metformine dans des situations d'accumulation de la molécule avec un terrain de métabolisme anaérobique.

A partir d’expériences cliniques, nous souhaiterions discuter des facultés d’appropriation de l’espace du sujet psychotique. Face au constat d’impasse que peut provoquer le récit du sujet psychotique, nous proposons une méthodologie alternative axée sur le rapport du sujet à sa propre géographie et à sa faculté de « territorialisation ». Étude territoriale donc, qui ne se réduit pas à une réflexion sur l’espace mais intègre forcément aussi la temporalité, le geste et les rythmes pour, fondamentalement réfléchir au statut épistémique du sens et de la sensation psychotique. Les actes, que phénoménologues et éthologues appellent ritournelle, ajustement social, régulation affective ou encore intuition relationnelle, sont un ensemble de petits gestes quotidiens qui va donc prendre une valeur d’analyse significative dans la problématique du sujet psychotique. C’est donc à travers l’espace investi, le territoire, et la capacité à faire œuvre de territorialisation et de ritournelles que le sujet psychotique va proposer un mode d’expression où la question centrale devient : comment être au milieu des autres ? Cette question qui apparait à tout-un-chacun dans sa composante intuitive, automatique et quasiment inconsciente semble chez le psychotique le submerger. Ce sentiment de déterritorialisation irait de pair avec ce qu’il convient d’appeler une crise identitaire. Le socle social de l’identité propre est ici vacillant ; il y a trouble de l’ajustement corporel et dissolution du corps commun. L’ensemble des conventions sociales implicites devient un ensemble d’énigmes ou d’impasses explicites auxquelles le sujet ne parvient pas à répondre. Enfin, le phénomène de territorialisation doit aussi pouvoir s’inscrire dans la temporalité. En effet, la territorialisation n’aura d’effet que si elle se répète, s’inscrivant alors dans le temps. Cette inscription temporelle, permet d’introduire cohérence et articulation entre différents événements. L’unité même d’un objet, pour apparaître à la conscience, suppose le temps. Husserl le démontre en décrivant l’audition d’une mélodie. Si l’on isole les différentes notes, chacune prise comme une réalité isolée, une idée globale de la phénoménalité de la mélodie est tout simplement impossible. Ce sont l’articulation et l’enchevêtrement des mesures qui vont permettre la perception auditive de la mélodie et d’échapper à la monotonie ou la cacophonie. Le psychotique serait voué à vaquer du chaos au néant, de cette monotonie à la cacophonie sans jamais rencontrer un « quotidien-changeant » essentiel à la territorialisation et à l’inscription sociale.

La technique LIBS (Laser Induced Breakdown Spectroscopy) permet une analyse rapide in situ des éléments chimiques sans préparation de l'échantillon. La LIBS consiste à illuminer un échantillon à analyser avec une impulsion laser nanoseconde et concentrée par un système optique. Il en résulte la production en surface du matériau d'un plasma qui émet de la lumière dont le contenu spectral est ensuite analysé à distance. La LIBS a diverses applications dans le secteur de l'environnement. Dans la présentation, nous mettons en avant les applications dans la recherche de polluants ainsi que la possibilité de trier les vitrocéramiques dans les déchets verriers.

This bibliographical study falls under the context of researching financial autonomy for durable management of South countries’ wastewater ponds (WSP), and growing interest on shellfish zooplanktons that contribute to water treatment and can be recovered in aquaculture and many industrial applications. Our project w ill start by gathering available data aiming at the development of a mathematical model of the contribution of zooplankton in pond ecosystems. This model would include the effect of most driving factors on the growth of shellfish zooplankton in WSP combined with water treatment effi ciency and biomass productivities. After a description of various types of WSP and their corresponding zooplanktons, emphasis is put on the shellfish cladocerans, especially Daphnia. The range of growth rates in various conditions is provided and expressions of growth kinetic, merging the effect of most important factors identified. These expressions of kinetic and the corresponding stoichiometry will serve as a first approach in our model. We hope that this type of research will help in the development of sustainable sanitation systems in developing countries. [less ▲]

In the course of our investigations on Strychnos usambarensis leaves in order to isolate isostrychnopentamine, the main alkaloid responsible for the antiplasmodial activity of the plant, a new tertiary indolic alkaloid has been isolated: 17-O-acetyl, 10-hydroxycorynantheol 1. Its structure was determined by means of spectroscopic and spectrometric methods such as UV, IR, CD, NMR and ESI-MS. 17-O-acetyl, 10-hydroxycorynantheol 1 is one of the most active monomeric indole alkaloid known to date showing an in vitro activity against Plasmodium falciparum close to 5 µM and a high selectivity.

Œuvre originale de la première moitié du XVIIIe siècle, Le Cuisinier gascon est certainement l’un des ouvrages culinaires les plus énigmatiques de son époque. Publié de façon anonyme, le livre est aujourd’hui attribué au Prince de Dombes, frère du comte d’Eu et grand veneur de Louis XV avec lequel il partage le goût de la chasse et des bons repas. L’ouvrage présente deux cent dix-sept recettes disparates dont l’écriture ne déroge à aucune règle fondamentale : concision et efficacité du style, sobriété de la syntaxe, homogénéité des moyens d’expression de l’injonction. En effet, la recette de cuisine, par sa nature prescriptive, laisse peu de place aux figures stylistiques et à la créativité de son auteur. En réalité, le seul espace qui permet de laisser quelque latitude à l’imagination est concentré dans l’intitulé du plat décrit. Or, Le Cuisinier gascon présente de nombreuses désignations de plats fantaisistes et, en particulier, un nombre impressionnant de dénominations « étrangères » telles que les Cuisses de poularde à la Suisse ou les Poulpettes à l’Italienne. Il est donc évident que l’ouvrage se veut cosmopolite, résolument tourné vers l’ailleurs – qu’il soit géographique ou imaginaire. De manière générale, nous nous demanderons dans quelle mesure les emprunts lexicaux tels que Woatre fiche, oille et niocs peuvent être considérés comme des transferts culturels, à la fois matériel (la spécialité culinaire) et linguistique (sa dénomination). Peut-on voir dans cet exotisme culinaire le signe d’influences culturelles entre des pays dont les frontières politiques ne cessent de se redessiner durant un siècle éclairé par les Lumières ? En particulier, deux types de désignations problématiques retiendront notre attention ; le premier type portant sur « l’ailleurs spatial » et le second sur « l’ailleurs imaginaire ». Premièrement, on note de nombreux adjectifs invariables construits sur le modèle « à la + adj. fém. sg. » : les uns réfèrent à des régions (à la Provençale) et les autres à des entités culturelles plus vastes (à l’Espagnole). Si le lien entre la désignation et la référence est parfois évident (par exemple, on trouve presque invariablement du parmesan dans la composition des plats à l’Italienne), il peut s’avérer abscons dans d’autres cas ; ainsi, nous rencontrons des Choux à la Turque et des Foyes gras à l’Indienne qui n’ont rien d’oriental. Ces qualifications sont-elles purement fantaisistes ou ont-elles une explication rationnelle ? Ces adjectifs font-il véritablement référence à une nation ou plutôt à une tradition, à un événement historique ou à une personnalité ? Deuxièmement, on observe des désignations inédites, propres au Cuisinier gascon : les Yeux de veau farcis au gratin, le Hachis d’œufs sans malice et le Veau en crotte d’âne roulé à la Nenteau en sont les meilleurs exemples. Ici, ce ne sont plus les frontières géographiques qui sont franchies, mais celles du réel. Comment comprendre l’étrangeté de ces appellations qui mêlent la représentation imagée des aliments et une poésie pleine d’humour ? Ne pourrait-on lire dans cette liberté nominative la volonté de l’auteur-cuisinier de s’émanciper en s’appropriant la matière culinaire grâce à l’usage qu’il fait de la langue ? Par l’étude de quelques désignations, nous verrons à quel point les transferts culturels imprègnent la gastronomie de l’époque et lui permettent d’évoluer. De plus, nous envisagerons la possibilité que le cuisinier, en introduisant l’étrange ou l’étranger dans son texte, devienne lui-même autre (un véritable auteur) et qu’il emmène le genre culinaire vers un ailleurs: la gasconnade.
