The session is devoted to the launch of an online knowledge database specific to GP / FM. This work is the result of a two years’ work of a cooperative project between participants from 12 countries and 8 languages. People are now used to the International classification of Primary Care (ICPC-2) which addresses the clinical issues in GP/FM , ie Symptoms, Process and Diagnosis. We have work on non-clinical issues i.e. all themes addressed by GPs during congresses which concern organizational, ethical, structure, teaching or patient related issues not encompassed by ICPC-2. The letter Q was used to name Q-Codes because this letter wasn’t yet used in ICPC-2. Q-codes are a classification of non-clinical items in General Practice / Family Medicine (GP/FM). Q-codes are a classification of non-clinical items in General Practice / Family Medicine (GP/FM). After a demonstration of the Q-Codes terminology and of the online database, we are proud to present to you a new GP/FM terminology in 6 languages freely available online.

Le but de la présentation est de synthétiser les connaissances sur le contrôle de la dynamique du phytoplancton par les contraintes environnementales dans un site de référence méditerranéen. L’étude est réalisée en Baie de Calvi (Corse) à la station PHYTOCLY (42°34.85'N, 08°43.71'E) où des séries temporelles haute fréquence de données physiques, chimiques et biologiques sont réalisées depuis 1979. Depuis 2006, l’acquisition des données de subsurface et le traitement des échantillons, qui inclut des analyses HPLC de contenu pigmentaire du phytoplancton et des comptages de flore totale, sont réalisés grâce au soutien de la DCE. En Baie de Calvi, l’intensité de la rigueur hivernale, identifiée par deux proxys, la température de l’eau et le nombre de jours de vent fort, contrôle le réapprovisionnement en sels nutritifs des couches de surface et le développement du bloom phytoplanctonique (détails dans Goffart et al., 2015, Progress in Oceanography). Lors des années caractérisées par un hiver rigoureux (e.g. 2010), le bloom phytoplanctonique hivernal se développe pendant la période d’eau froide (eau de subsurface ≤13.5°C). Il est dominé par les diatomées et les cryptophycées, deux groupes qui montrent une préférence marquée pour les eaux froides et riches en sels nutritifs. Lorsque l’hiver est très doux (e.g. 2007), la disponibilité en sels nutritifs est réduite et le bloom ne se développe pas. Les diatomées et les cryptophycées sont absentes, et les communautés phytoplanctoniques sont dominées par les prymnesiophycées pico- et nanoplanctoniques et les cyanobactéries. Les résultats de l’étude permettent aussi : • de fixer les limites de la variabilité naturelle du phytoplancton dans un site de référence méditerranéen, • d’expliquer les variations interannuelles de biomasse et de composition phytoplanctonique, • de définir les préférences écologiques des différents groupes phytoplanctoniques, • d’établir des courbes d’évolution saisonnière des principaux groupes phytoplanctoniques qui intègrent la variabilité interannuelle liée aux variations climatiques. La connaissance acquise au cours de cette étude permet de contribuer au développement d’indices de qualité intégrant la composition du phytoplancton (e.g. indice de composition I C MEDIT) et de tester des méthodes de surveillance à grande échelle (e.g. croisement des suivis pigmentaires réalisés à haute fréquence et de l’imagerie satellitaire), contribuant ainsi à la mise en œuvre des politiques publiques (DCE, DCSMM).

Dans les églises des congrégations féminines, la problématique du « voir » est étroitement associée au « ne pas être vu ». Plus encore que leurs homologues masculins, moniales et religieuses, implantées en milieu urbain tout en étant soumises à la stricte clôture, ont dû trouver des solutions architecturales qui satisfassent à ces deux exigences. Dans ce contexte, les enjeux se focalisent en particulier sur l’articulation de l’église « extérieure » et de l’église « intérieure » – pour reprendre l’expression de Carlo Borromeo – où se déroulent les principaux moments de la vie liturgique de la communauté. En examinant les églises de trois ordres méconnus implantés aux frontières de la catholicité entre le XVe et le XVIIIe siècle (chanoinesses du Saint-Sépulcre, bénédictines réformées de la Paix Notre-Dame et annonciades célestes), il s’agit d’analyser tant la forme (plan, décor, mobilier) que la fonction des nouvelles constructions, mais aussi les aménagements – bien moins connus – des églises monastiques préexistantes et des maisons particulières acquises lors de la fondation.

The theorem of Büchi-Bruyère states that a subset of N^d is b-recognizable if and only if it is b-definable. As a corollary, the first-order theory of (N,+,V_b) is decidable (where V_b(n) is the largest power of the base b dividing n). This classical result is a powerful tool in order to show that many properties of b-automatic sequences are decidable. The first part of my lecture will be devoted to presenting this result and its applications to b-automatic sequences. Then I will move to b-regular sequences, which can be viewed as a generalization of b-automatic sequences to integer-valued sequences. I will explain how first-order logic can be used to show that many enumeration problems of b-automatic sequences give rise to corresponding b-regular sequences. Finally, I will consider more general frameworks than integer bases and (try to) give a state of the art of the research in this domain. [less ▲]

Objective : Blood pressure (BP) control in chronic hemodialysis (HD) patients is a major challenge and could explain the controversial results about its cardiovascular risk. Our study aimed to assess the contribution of two ambulatory techniques of measurements compared with office BP (OBP): ambulatory monitoring during a maximum of 44h interdialytic period (ABPM) and home blood pressure (HBPM) during a variable period of days in prevalent HD patients. Methodology : 43 prevalent chronically HD patients (M=28; F=15), mean age 68.3±13 years were submitted to a 44h monitoring of BP (Spacelabs 90207) from the end of an HD session to 10 minutes before the next session, immediately followed by a 7days HBPM (Omron M6). Office BP was the mean of pre-dialysis BP or post-dialysis-BP recorded over 2 weeks (6 HD sessions). Hypertension was defined as BP equal or higher than 140/90 mmHg for pre-HD, 130/80 mmHg for post-HD, 130/80 mmHg for 44 h ABPM and 135/85 mmHg for HBPM. Results : Good correlations were noted between ABPM and HBPM for the diagnosis of hypertension in HD patients. Both ambulatory techniques give the same proportion of masked hypertension and white coat hypertension compared with OBP (25%). The best diagnostic precision was noted for the longest periods of recordings (44h for ABPM and 7days for HBPM). Shorter periods were more practical for the patients but less precise for high BP identification. HBPM was more appreciated than ABPM by the patients Conclusion : ABPM and HBPM identified a quarter of patients with a particular phenotype of hypertension not correctly classified by OBP. HBPM should be first recommended in HD (at least 1 week/month). As ABPM provides unique information for nocturnal BP, it could be proposed 1 time/year in all patients. [less ▲]

Background The distinction of dermatophytes strains by conventional methods is problematic due to a lack of reliable characteristics between isolates. The ability to identify individual organisms allows identification of infection sources, such as communal swimming and public washing rooms and apply appropriate control measures. Several outbreaks of dermatophytes infection have already been described in Europe and the feasibility of comparing DNA fingerprints is of interest in this particular field. We have successfully applied the rep-PCR method for typing dermatophytes species such as Microsporum audouinii, Trichophyton violaceum and Trichophyton mentagrophytes complex (T.mentagrophytes complex). Methods The Diversilab® system (bioMérieux, France) has been used to perform rep-PCR. Strains of M. audouinii (116) and T. violaceum (23) were collected during a national survey conducted by the National Reference center (NRC) for mycoses (Liège) in Belgium from February 2013 to March 2014. Strains of T. mentagrophytes complex (32) are part of the national collection of the NRC collected between 2012 and 2015. Results The Diversilab® is able to distinguish different subspecies between the same species complex as it was confirmed with the T. mentagrophytes complex. For this group of strains, two major groups are clearly visible after Diversilab analysis and correspond to white strains (ITS sequenced as T. interdigitale) and yellow strains (ITS sequenced as A. benhamiae) of T. mentagrophytes complex. Both groups share only 70% of similarity. Within a same species of dermatophyte, the Rep-PCR is also able to define several subgroups sometimes linked with epidemiological factors. Inside the T. violaceum strains circulating in Belgium, two different DNA fingerprints have been found. These two subgroups were well separated regarding the geographical location in Belgium (Wallonia and Flanders). Inside the M. audouinii species, 6 different DNA fingerprints have been detected with a main group. The degree of similarity between these six groups is comprised between 85,6% and 94%. Strains belonging to the six groups were defined as M. audouinii by ITS sequencing. Conclusion The DiversiLab® system with the Rep-PCR technology proved to be an efficient method for dermatophytes molecular typing. It is highly sensitive to discriminate small genotypic variation between two strains within the same species which is not possible with other molecular methods such as ITS sequencing. Inside the T. mentagrophytes complex, it permits to easily distinguish the yellow zoophilic strains from the white anthropophilic strain, hardly possible by microscopy. [less ▲]

L’hypothèse générale qui sous-tend cette conférence est que le mental animal est une perception émergente liée aux conditions de l’interaction entre une personne humaine et un animal. Si on compare la manière dont un chercheur ou un propriétaire d’animal de compagnie perçoivent les caractéristiques mentales de leur animal, il est évident que le type de « mind » qui est perçu est le produit d’une interaction, d’une manière de se relier au monde de la vie, ainsi que d’un certain nombre de conceptions sur « ce qu’est » un animal. C’est ainsi que des modalités relationnelles différentes vont amener un sujet à expérimenter/découvrir des minds animaux très différents.

Creating wildflower strips is often suggested as a tool to support pollinator diversity in agricultural landscapes and to promote crop pollination service. The choice of the plant species to sow in flower strips can influence the effectivity of the strips in supporting pollinators. While it has already been shown that increasing plant species diversity is beneficial for ecosystem services, it is often suggested that plant functional traits and functional trait diversity are the key for this relationship. We created a replicated field experiment with different levels of plant functional diversity in wildflower strips in Belgium to test the effect on the flower-visiting pollinator community. We sampled plant-pollinator interaction networks during 2 years and assessed how the plant functional diversity affected the network structure. Plant functional diversity did not have a clear effect on visiting pollinator species richness, however a different interaction pattern was observed with different functional diversity level. Pollinators in wildflower strips with higher functional diversity had less overlap in their ecological niche, while network stability and robustness for secondary extinctions were not affected. We discuss implications for wildflower strip design. [less ▲]

The aim of this study is to have a good understanding of the environmental impact of glucose production to be able to study material produce from glucose. Glucose is general-ly produced from corn or wheat. Since agricultural processes are known to be difficult to evaluate by LCA, the results obtained with two different LCA databases, Gabi and EcoIn-vent, are compared in this work. The production of glucose from raw materials can be divided in two steps: the agricul-tural step allowing the plant production, and the conversion step including the extraction of the starch from the plant and its hydrolysis into glucose. Preliminary results underline the high impact of the agricultural step, so a special attention has been paid to these data. Specific Belgian data collected by the Walloon Agricultural Research Centre (CRA-W) (2014) [1] have been used as primary data (yield, amount of fertilizers, etc.), either using EcoInvent or Gabi datasets background data to model fertilizers, diesel consumption, etc. A third model was built using only data available in Ecoinvent for corn and wheat cultures. For the conversion step, literature data have been used along with some industrial data. As few studies are available in the literature concerning starch hydrolysis, the focus has been placed on data validation (mass balance checks, cross-reference information, etc.). Based on these multiple sources, it is possible to compare the LCA results for the pro-duction of 1 kg of glucose for three different cases, summarized in the following table. Table 1: Summary of modelled cases Agricultural step Conversion steps Primary data Dataset Primary data Dataset Case 1 Belgian GaBi Literature + Industry GaBi Case 2 Belgian Ecoinvent Literature + Industry Ecoinvent Case 2 Ecoinvent Literature + Industry Ecoinvent The results obtained using these three models will be presented, at both the inventory and impact assessment steps. They show significant differences and highlight the need to understand in depth the involved assumptions when developing the datasets, in addition to the ones adopted for the inventory. These differences in results lead to higher uncer-tainties, allowing only to have a range of possible values as a result. We make the choice to only communicate this range of value and not an absolute value when communicating the results of this study but this leads to some disadvantages such as difficulties in com-parison, etc. [less ▲]

The monitoring of coastal environments remains a research domain of great interest and concern. Coastal ecosystems are threatened by natural and human-induced stressors and are, as transitional environments, particularly sensitive to disturbances. EcoNum first research thematic revolves around hermatypic corals, calcifying organisms, and their adaptation potentials to environmental changes including by using original and patented chemostats. The studied organisms are grown and maintained in artificial mesocosms that simulate environmental conditions of a natural system. This infrastructure allows to perform long-term experiments, giving time to organisms to adapt to the tested conditions (e.g., increased temperature or lowered pH). Longer-term studies have demonstrated that many organisms are more resistant to environmental stressors than previously observed on the short-term. EcoNum also studies coastal plankton abundance and diversity. Plankton is particularly sensitive to physicochemical changes of water bodies. The classification and the enumeration of planktonic organisms require specialized tools in order to analyse time series of multiple samples. EcoNum has developed a software for the semi-automatic classification of planktonic organisms called Zoo/PhytoImage. This software has been used to study a 10-year time series of coastal Mediterranean zooplankton samples. The concomitant analysis of environmental parameters registered at high frequency with specific statistical tools such as the R package pastecs allows to understand the processes governing the changes observed in plankton assemblages. The use and the development of statistical tools in R (e.g., Zoo/Phytoimage, pastecs) is a priority of EcoNum to favour open access knowledge and reproductive sciences. EcoNum research topics also focus on coastal ecotoxicology. Chemicals, including trace elements, remain contaminants of concern, mainly in coastal environments that are the final sink of inland pollution sources. The chemical integrity of coastal ecosystems thus has to be accurately monitored. The partitioning of chemicals between their dissolved, particulate and sedimentary phases does not provide information on their bioavailability. EcoNum thus monitors coastal waters using bioindicator species such as seagrasses, mussels or sand worms. A global map of the contamination of the Mediterranean by trace elements has been drawn using seagrasses has bioindicator species. EcoNum also studies trace element ecology and toxicology. For instance, it has demonstrated the toxicity of copper on the coral Seriatopora hystrix and it's symbiont's photosynthetic processes, or its bioaccumulation and basipetal translocation towards rhizomes in the seagrass Posidonia oceanica as reserve nutrient for subsequent leaf growth. Finally, coastal vegetated systems are potential carbon thinks (or sources) in the global carbon cycle. Therefore, EcoNum studies the primary productivity of seagrass meadows, from the individual to the community, with measuring techniques as diverse as PAM-fluorometry or biomass production determination. To conclude, EcoNum is a research unit devoted to marine environment monitoring. It develops research thematics on major coastal communities such as coral reefs, seagrass beds or plankton assemblages and studies their natural dynamics and the effects of stressors on their global functioning.

Natural soft clay exhibits a considerable degree of anisotropy as a result of its past sedimentation and consolidation history. It also tends to have significant inter-particle bonding, which affects its mechanical behavior. The natural structure of in-situ soils makes their behavior different from that of a reconstituted material. In fact, most clays lose a proportion of their strength when remoulded. Various authors proposed anisotropic elastoplastic soil models allowing the yield surface to rotate with the stress history. These models have a “rotational hardening law" which relates the change of the inclination of the yield surface to the current soil state and to the increments of the plastic volumetric and/or shear strain, [Sekiguchi and Otha (1977)], [Hashiguchi and Chen (1998)], [Wheeller et al (2003)]… Other authors combine the plastic anisotropy with destructuration effects observed in soft sensitive soils by assuming that the size and /or the position of the center of the yield surface depends on the amount of the structural soil degradation. These models use an additional isotropic hardening law that relates the size and/or the position of the yield surface of the intact sample to that of the reconstituted one [Nova et al (2003)]. The previous models provide little or no flexibility when it comes to describe the change of the plastic modulus with the loading direction as they are unable to produce a smooth degradation of the stiffness, being single yield surface models. A way to improve this behavior is to introduce the “bounding surface plasticity” theory, initially developed by Dafalias [Dafalias and Herrmann 1986]. Unlike a single yield surface model, the bounding surface theory allows a smooth transition of stresses within and on the bounding surface. The mean feature of this concept is that the actual stress is mapped to the imaginary stress on the bounding surface. The distance between the real and imaginary stress, which is called the “ function distance ”, is used to specify the plastic modulus. This work presents a bounding surface plasticity model for natural and structured clays based on the critical state theory. A novel rotational hardening rule for clays is presented, and a hardening function distance is introduced to describe the evolution of the bounding surface. Validation of the model is provided by drained and undrained tests of Scottish and Finnish intact and reconstituted clays [Kastunnen 2008]. Finally, finite element simulations of a foundation considering the formulated constitutive law are presented. [less ▲]

The probability of perceiving objects in a group as being similar to each other is a negative exponential function of the distance between them in a psychological space (Shepard 1987). Here I summarize results from recent experimental studies showing that the psychological distance and thereby the similarity between objects of the same category depends on object properties such as size, frequency, and manipulability. For example, people judged elephants to be more different from each other than ants are. Further results show that irrelevant object properties evoked by digit-word expressions modulate numerosity estimations. For example, people judged “8 elephants” to be more numerous than “8 ants”. Taken together, these findings demonstrate that individuals need not directly perceive specific object properties in order to develop numerosity estimation biases (cf. Binet 1890) but promptly and unduly take into account irrelevant object properties when the objects are being merely mentioned, suggesting that words can instantly access rich mental representations that subsequently affect measurement estimations. Additional experimental findings suggest that emotional states can also impact measurement estimations. [less ▲]

The analysis of the of Silva’s collection of works places us in quite a disconcerting, yet no less encouraging, position, when re-assessing the different forms of importing literary movements. On one hand, the image attributed to Silva both by his contemporaries and his successors is that of the leading figure in the assimilation and absorption of the literary European movements that would give rise to modernism. On the other hand, the absence of public visibility for Silva’s works, be it through texts or paratexts, let us in a difficult situation to prove the poet’s will to position himself as the one who introduced the new literary movement to Colombia. If we accept from the outset, as we will in this article, that the Colombian poet possessed an obstinate determination to appropriate and assimilate the European literary movements that give rise to modernism, then we must entertain the possibility that Silva’s literary transfer took place through media other than books, journals or magazines. Our hypothesis is that by focusing on the acts of reading and poise, the literary coterie became the ideal platform for the Colombian writer to adopt and propagate the image of the decadent writer, which would become the embodiment of the aesthetic ideals of modern literature.

Le diagnostic médical d'une pathologie est un événement significatif dans les parcours de vie des patients et de leurs proches. Il vient catégoriser des symptômes, participer aux processus de (re)construction de soi, et induire des attitudes et comportements en vue d'intervenir activement sur les événements. Notamment, il correspond pour certains au moment de leur engagement au sein d'une association concernée par la pathologie ou le syndrome diagnostiqué en question. De telles associations de patients s'impliquent souvent dans diverses activités de production, de mobilisation et de circulation de connaissances sur les conditions et leurs causes. Ces modes d'activisme dits "basés sur la connaissance" (evidence-based activism) se caractérisent par une articulation étroite entre des connaissances issues d'expertise biomédicale et des connaissances expérientielles, issues des expériences vécues au quotidien par les patients et leurs proches, dont ils revendiquent la légitimité. S'inscrivant à la croisée des Science and Technology Studies et de l'anthropologie de la santé et de la maladie, la présente communication vise à explorer les dynamiques de cette articulation à partir d'une ethnographie multi-site menée auprès d'associations belges francophones concernées par des pathologies ou syndromes génétiques. Plus particulièrement, la communication s'intéresse à un projet d'information et de sensibilisation autour du trouble du spectre autistique (TSA) qui est développé par un groupe de parents concernés. Le TSA y est défini comme une condition complexe et multidimensionnelle, aux causes incertaines et controversées mais dont ils revendiquent la part déterminante de la génétique. Comment des "connaissances expérientielles" sont-elles produites, validées et mises en circulation dans le cadre de telles activités ? Au-delà de la simple information, les observations montrent qu'elles comportent des enjeux identitaires importants. [less ▲]

Dans les années 60, Grothendieck révolutionna la géométrie algébrique en introduisant le concept de topos. Faisant face à des situations où la notion d'ouvert était trop restrictive pour comprendre les phénomènes géométriques sous-jacents, il définit une nouvelle notion de topologie dans le langage de la théorie des catégories. Très utilisée pour résoudre des problèmes de géométrie et d'analyse contemporains, cette notion a aussi de nombreuses applications surprenantes en logique (théorie intuitionniste, équivalence de Morita, etc ...). Dans ce séminaire je proposerai une application de la théorie des topos de Grothendieck pour étudier les fonctions et les distributions tempérées. En effet, ces objets ne forment un faisceau que sur une topologie de Grothendieck particulière (la topologie sous-analytique), qui n'est pas une topologie au sens usuel du terme. Je montrerai alors, de manière abstraite, comment définir un faisceau de fonctions holomorphes tempérées qui a joué un rôle crucial dans la démonstration de la correspondance de Riemann-Hilbert (généralisation du 21ème problème d'Hilbert). En particulier, ce nouveau faisceau fournira une nouvelle définition, presque purement algébrique, des distributions de Schwartz. [less ▲]

Las siguientes consideraciones metodológicas surgen esencialmente de la confrontación de la teoría de las transferencias con mi corpus actual de trabajo, esto es, con las modalidades de importación literaria durante el modernismo, época que, como todos sabemos, constituyó un momento de apertura privilegiado para la apropiación y asimilación de las producciones culturales extranjeras. Los escollos metodológicos encontrados a medida que avanzábamos en la problematización de nuestro corpus sirvieron pues de estímulo para integrar y transponer algunos conceptos y herramientas teóricas tomados principalmente de la teoría de los campos de Pierre Bourdieu, del análisis del discurso a la manera de Dominique Maingueneau y de la poética histórica de los soportes tal y como ha sido desarrollada en Francia por Alain Vaillant y Marie-Ève Thérenty. Es a partir de dicho diálogo que podemos hoy afinar ciertos conceptos y herramientas teóricas indispensables para repensar algunos puntos ciegos de la teoría de las transferencias. [less ▲]

Il existe actuellement un consensus sur le fait que les scientifiques ne décrivent pas la réalité telle qu’elle est dans toute sa complexité mais qu’ils en construisent des représentations qui leur permettent de l’expliquer partiellement et de la maîtriser, partiellement également. De telles représentations sont généralement appelées des modèles et le processus de leur construction est la modélisation. Les référentiels et programmes de sciences insistent de plus en plus, dans un souci d’authenticité épistémologique, sur la nécessité de confronter les élèves aux modèles établis et à leur élaboration, afin qu’ils se constituent une vision aussi fidèle que possible de l’entreprise scientifique. Le concept de modèle possède des composantes multiples et il n’est pas aisé d’en donner une définition compacte, complète et définitive. On pourrait tenter de dire, en bref, que modéliser, c’est simplifier délibérément pour pouvoir expliquer et agir efficacement. On peut envisager différents types de modèles qui ne s’excluent pas mutuellement. On les rencontrera dans les différentes activités expérimentales que nous proposons. (i) On peut tout d’abord modéliser une situation expérimentale complexe (une pile commerciale ou un accumulateur, par exemple) par une autre situation apparentée mais plus simple et dont on contrôle mieux les paramètres, afin de mettre leur influence en lumière. Diverses expériences sur les piles (de Daniell, entre autres) illustrent cet aspect. Les expériences proposées sur la diffusion entrent également dans cette catégorie. (ii) En chimie, le principe explicatif fondamental consiste à fonder les observations macroscopiques sur des processus décrits au niveau sub-microscopique (atomes, molécules, ions, électrons). Cette représentation sub-microscopique peut être schématique et/ou symbolique. Pour plusieurs des expériences proposées, on demande de représenter schématiquement les mouvements des particules concernées. On demande aussi de traduire le phénomène en un langage symbolique, l’écriture de la réaction chimique. Ici aussi, il s’agit d’une modélisation : quand on écrit HCl(aq), par exemple, on remplace une situation complexe et relativement mal définie – des ions H3O+ et des ions Cl- hydratés avec éventuellement plusieurs couches d’hydratation – par une écriture compacte qui représente de manière conventionnelle l’essentiel de l’information dont on a besoin dans un but déterminé (un titrage, par exemple).

The YROSIAE (Year Round survey of Ocean-Sea Ice-Air Exchanges) survey aimed to carry out a year-round survey of land-fast sea ice focusing on the study of sea ice physics and biogeochemistry. Ice cores, sea water, brines material were collected at regular intervals about 1 km off cape Evans in McMurdo Sound, Antarctica, from November 2011 to December 2011 and from September 2012 to December 2012. Samples were processed to characterize both the vertical distribution and temporal changes of climate gases (CO2, DMS, CH4, N2O), CO2-related parameters (ice-air CO2 fluxes, dissolved inorganic carbon, total alkalinity and CaCO3 amount), physical parameters (salinity, temperature, and ice texture), biogeochemical parameters (macro-nutrients, particulate and dissolved organic carbon, δ13C, δ30Si and δ15N) and biological parameters (chlorophyll a, primary production within sea ice derived from O2:Ar and O2:N ratios…). Very high chlorophyll a abundance was observed at the bottom of the ice, a common feature of land fast ice in McMurdo Sound. During spring, chlorophyll a exhibited a significant increase suggesting high primary production. . However, at the same time, nutrients at the bottom of the ice increased significantly suggesting high remineralization and heterotrophy. In the middle of the ice column, evolution of dissolved inorganic carbon shown a succession of autotrophic and heterotrophic phases. However, the overall increase of DIC suggests that the ice interior was rather heterotroph. This was consistent with the increase in nutrients observed at the bottom of the ice. Such sea ice system should expel CO2. Yet, strong under saturation in CO2 in surface ice, and negative air-ice CO2 fluxes suggested that sea ice was taking up CO2 from the atmosphere. Meanwhile, measurements of N2O within the sea ice suggest that the ice was releasing N2O to the atmosphere as a result of high nitrification. On the whole land fast sea ice in McMurdo Sound appears as a puzzling ecosystem. It is able to support elevated growth of autotrophic organisms, but appears to be heterotrophic, yet pumping CO2 to the atmosphere but releasing other greenhouse gases. [less ▲]

Le présent article s’intéresse à la reconfiguration du contrôle managérial face à une des évolutions actuelles des formes de travail, à savoir le travail à distance. Après avoir circonscrit ce concept et à partir d’une étude empirique menée au sein d’un groupe international du secteur des télécommunications, cette thématique particulière est abordée à l’aune de la sociologie de Goffman. Cette dernière s’avère singulièrement riche pour appréhender les changements, y compris digitaux, qui prennent place à l’heure actuelle dans les organisations. L’apport goffmanien est double : le propos de l’auteur constitue, d’une part, les bases de la méthodologie ethnographique de recueil des données élaborée et, d’autre part, l’éclairage théorique choisi pour discuter les résultats empiriques. Il apparaît ainsi que le contrôle managérial du travail à distance donne naissance à des situations paradoxales au sein desquelles s’opposent l’invisibilité engendrée par l’absence intra muros et l’hypervisibilité mise en place lorsque les personnes sont présentes dans les établissements physiques de l’entreprise, d’une part, et à travers les outils technologiques, d’autre part. La recommandation classique de la littérature prônant le passage à une direction par objectifs s’avère insuffisante pour répondre à l’enjeu du contrôle managérial. Les conclusions de cette recherche suggèrent davantage une hybridation réfléchie des modes de contrôle articulés autour d’une relation de confiance. [less ▲]

While representing less than 5% of the total ice cover around Antarctica, fast ice is nevertheless an important habitat with highest biomass and production occurring in the bottom (Archer et al., 1996). Sea--‐ice algae are playing a key role in structuring the ecosystem, as they are an essential food source for krill. With the annual melting of the sea ice there is a strong release of nutrients and algae to the water, possibly fertilizing and/or seeding algae the underlying water column. A time series was sampled during the Austral spring of 2015 (Oct. 27th – Dec. 11th), in the vicinity of Davis station (68°35’ S, 77°58’ E, Prydz Bay, Antarctica). Fast ice, snow cover and underlying water column were sampled with focus on the nitrogen and carbon cycle and the pivotal role of sea--‐ice algae for higher tropic levels. Different parameters such as nutrients, particulate matter (PM) and isotopic signatures for nitrate, ammonium and PM will be measured. Primary production and uptake rates for different nitrogen substrates were also measured using in--‐situ stable isotope incubation experiments to study the change in algae growth rates. That campaign was performed in close relation with colleagues from the Institute of Marine and Antarctic Studies (Hobart, Australia) to link our findings with the availability of trace metals such as iron. Temperature profiles in the ice showed a clear change halfway the sampling campaign with increasing temperatures, likely accompanied by an increase in permeability throughout the ice. Results show a large accumulation of biomass in the bottom few 5 cm (particulate organic carbon reaching up to 1300 μmol l‐1). Preliminary data also shows a large accumulation of nitrate at the bottom with concentrations exceeding those in the underlying water. Preliminary results will be presented and discussed. [less ▲]

La parentalité est un concept difficile à définir car il s’inscrit à la fois "dans le champ social, juridique et psychologique" [1]. De nos jours, le « devenir parent » est décrit comme un processus dynamique, qui débute dès le désir d’enfant, et qui s’accompagne de remaniements psychiques importants chez les deux parents. Depuis plusieurs années, des études se sont intéressées à l’impact de la précarité sur la sphère familiale. Il est aujourd’hui reconnu que la précarité psychosociale impacte toutes les dimensions du développement de l’enfant et plusieurs dimensions de la parentalité (sensibilité parentale, disponibilité émotionnelle, pratiques éducatives, …). La précarité est définie comme « l’absence d’une ou plusieurs des sécurités, notamment celle de l’emploi, permettant aux personnes et aux familles d’assumer leurs obligations professionnelles, familiales et sociales, et de jouir de leurs droits fondamentaux » [2]. Selon Furtos, à la précarité économique s’ajoute la précarité psychosociale et, parfois, un syndrome d’auto exclusion sociale. Selon lui, « d’un côté, l’environnement est excluant, tandis que de l’autre côté le mot « auto » renvoie à la part du sujet : tout en subissant une situation d’exclusion, le sujet a la capacité d’exercer sur lui-même une activité pour s’exclure de la situation, pour ne pas la souffrir, transformant ainsi le subir en agir » [3]. Ce public est caractérisé par une problématique du lien. Entrer en relation, s’investir dans un suivi, maintenir une continuité du lien sont autant de défis pour les parents en syndrome d’autoexclusion sociale. Parvenir à les rejoindre nécessite donc de développer des structures flexibles et créatives, tant en ce qui concerne le suivi psychosocial que la recherche. Au travers de différentes recherches-action auprès de ces familles, nous avons été confrontés à la nécessité de développer un processus de recherche basée sur le lien pour accéder tant à l’évaluation de pratiques d’intervention et à l’évaluation du vécu de ces parents. Nos travaux ont montré combien le lien occupe une place centrale dans la prise en charge et dans la recherche avec des bénéficiaires en grande précarité psychosociale.

Les environnements flexibles sont en vogue. Présentés dans la littérature managériale comme un terrain d'émancipation pour les travailleurs, gages d'un accroissement de leur autonomie et de leur liberté, ils font désormais partie intégrante des projets de modernisation. Constatant un état des lieux plus alarmiste sur cette thématique dans la littérature académique, nous mettons en question le caractère réellement émancipatoire de ce type d'espace. Par une recherche empirique, conduite dans une entreprise publique belge, nous observerons une réalité plus nuancée. Quand ils ne font pas l'objet de réformes profondes de l'organisation du travail dès le tout début du processus de changement, ce type d'agencement est susceptible de se faire au détriment des travailleurs.

Les multiples systèmes, formes, catégories et pratiques de la parenté ont retenu l’attention des anthropologues comme une dimension centrale des façons dont les individus et les groupes humains conçoivent et vivent leurs rapports à eux-mêmes, aux autres, aux sociétés et au monde qui les entoure. Dans différents contextes et périodes historiques, des évolutions – tant démographiques, politiques, socio-culturelles, économiques, juridiques, scientifiques, médicales, ou encore relatives aux âges ou aux genres – ont contribué à sa (re)définition constante. Force est de constater que les innovations récentes concernant, entre autres, les technologies de procréation médicalement assistée et de gestation pour autrui, ou les débats autour du « mariage pour tous » et de l’adoption par des couples du même sexe, ont parfois été interprétés en termes de profondes ruptures par rapport à des conceptions plus « traditionnelles » de la parenté, ce qui leur confère un certain caractère inédit et polémique. D’un point de vue anthropologique, ces reconfigurations de la parenté témoignent de différentes modalités d’articulation entre le social, le culturel et le biologique, faits de société et faits de nature, construit et inné, dans la définition de la parenté. Cela amène à repenser la parenté dans toutes ses dimensions, du public à l’intime. Partant de l’anthropologie, et afin d’élargir le champ des réflexions empiriques, théoriques et épistémologiques, ce colloque invite à croiser les perspectives sur les (re)configurations contemporaines de la parenté dans les sciences humaines et sociales en privilégiant les approches ethnographiques. Il comprend deux axes principaux mais non exclusifs. Le premier axe entend appréhender les manières dont la question des (re)configurations contemporaines de la parenté est posée dans différents espaces publics et intimes. Le second axe ouvre quant à lui un débat épistémologique sur les regards croisés et comparatifs entre divers contextes, thématiques ou disciplines en invitant à analyser les enjeux, apports et limites issus de tels travaux de recherche.

Dans le champ intellectuel contemporain, la pensée de Paul Ricœur semble avoir pleinement intégré l’outillage conceptuel requis pour penser les identités et modes de subjectivation. Contre les conceptions du texte comme espace formel autorégulé, Ricœur a décrit le récit comme un dispositif cognitif fondamental, offrant aux individus et aux collectivités des modes de subjectivation et des prises sur le monde. Cette approche constitue un bénéfice disciplinaire non- négligeable pour les sciences humaines. Cette actualité de Ricœur peut sembler paradoxale. Certes, le concept de refiguration permet de penser les effets du récit dans le monde, à une époque où la diffusion massive d’information nécessite de capter l’attention par des récits efficaces (storytelling en politique, publicité, management, infotainment). Par contre, le concept d’identité narrative ne semble pas pouvoir se justifier de la même actualité. En effet, quoi de plus opposé à nos expériences démultipliées que cette forme narrative qui devrait les ordonner dans un récit unique ? Quoi de plus hétérogène que le vécu de l’individu contemporain, sans cesse sommé de s’adapter à de nouveaux rôles et de nouveaux projets ? Dans le cadre de cette communication, notre objectif sera d’évaluer la pertinence du concept d’identité narrative pour penser les modes de subjectivation individuelle, par le prisme de plusieurs romans contemporains (Farah, Delaume, Mérot, Minard, de Toledo, Vasset). Comment le récit de vie littéraire développe-t-il des formes qui puissent répondre aux expériences fragmentaires des sujets ? Ces formes renouvellent-elles l’usage de la narration et/ou de la fiction ? [less ▲]

Polarimetry constitutes one of the fundamental tools for characterizing the surface texture and composition of airless Solar System bodies. In 2006, polarimetric observations led to the discovery of a new type of asteroids, which displays a peculiar polarimetric response. These asteroids are collectively known as "Barbarians", from (234) Barbara the first discovered one.The most commonly accepted explanation for this perculiar polarization response seems to be the presence of a high percentage of fluffy-type Calcium Aluminium-rich Inclusions (CAIs), whose optical properties could produce the observed polarization. Their reflectance spectra also exibit an absorption feature in the near-infrared around 2.1-2.2 microns, that is characteristic of this peculiar group.Based on these results, we organized a systematic polarimetric and near-infrared observational campaign of known Barbarians or candidate asteroids. These campaigns include members of the family of 1040 Klumpkea, 2085 Henan and 729 Watsonia, which are known to contain Barbarian and/or L-type asteroids also suspected to have such a polarimetric behaviour. We have made use of the ToPo polarimeter at the 1m telescope of the Centre pédagogique Planète et Univers (C2PU, Observatoire de la Côte d'Azur, France). The spectroscopic observations in the near-infrared were obtained with the SpeX instrument at the NASA's InfraRed Telescope Facility (IRTF).By combining polarimetry and spectroscopy we find a correlation between the abundance of CAIs and the inversion angle of the phase-polarization curve of Barbarian asteroids. This is the first time that a direct link has been established between a specific polarimetric response and the surface composition of asteroids. In addition, we find a considerable variety of CAI abundance from one object to the other, consistent with a wide range of possible albedos. Since these asteroids constitute a reservoir of primitive Solar System material, understanding their origin can shed light on the processes driving the formation and transport of the refractory minerals that first condensed in the protoplanetary disk.

We apply the convex inversion method to the new optical data obtained by six instruments together with the already existing observations and derive convex shape model of low-perihelion near-Earth asteroid (3200) Phaethon. This shape model is then used as an input for the thermophysical modeling. We present new convex shape model and rotational state of Phaethon - sidereal rotation period of 3.603958(2) h and ecliptic coordinates of the preferred pole orientation of (319, -39) with a 5 degree uncertainty. Moreover, we derive its size (D=5.1±0.2 km), thermal inertia (Γ=600±200 J m-2s-1/2K-1), geometric visible albedo (pV=0.122±0.008), and estimate the macroscopic surface roughness by the thermophysical model. We also estimate the average size of the surface regolith to few centimeters. The Spitzer emission spectrum of Phaethon is similar to those of CV/CK carbonaceous chondrite meteorites, match with CI/CM carbonaceous chondrites is ruled out. We also study the long-term stability of Phaethon's orbit and spin axis by a numerical orbital and rotation-state integrator. We find that the Sun illumination at the perihelion passage during past thousands of years is not connected to a specific area on the surface implying non-preferential heating. Considering the most important meteor stream of the Geminids is associated with Phaethon, we predict that the meteorites dropped by Geminids are CVs or CKs. We also discuss the possible dynamical link between Phaethon and Pallas and its collisional family. [less ▲]

Ion mobility spectrometry (IMS) is a gas phase separation technique which relies on differences in the collisional cross section (CCS) of ions. Ionic clouds of unresolved conformers overlapped if the CCS difference is below the instrumental resolution expressed as Ω/ΔΩ. The experimental arrival time distribution (ATD) peak is then a superimposition of the various contributions weighted by their relative intensities. We have developed a strategy for accurate drift time determination using traveling wave ion mobility spectrometry (TWIMS) of poorly and unresolved conformers. This method implements through a calibration procedure the link between the peak full width at half maximum (FWHM) and the drift time of model compounds for wide range of settings for wave heights and velocities. We modified a Gaussian equation which achieves the deconvolution of ATD peaks where the FWHM is fixed according to our calibration procedure. The new fitting Gaussian equation only depends on two parameters: The apex of the peak (A) and the mean drift time value (µ). The standard deviation parameter (correlated to FWHM) becomes a function of the drift time. This correlation function between µ and FWHM is obtained using the TWIMS calibration procedure which determines the maximum instrumental ion beam diffusion using ionic compounds which are detected as single conformers in the gas phase. This deconvolution process has been used to highlight the presence of poorly resolved conformers for couples of crown ethers and peptides leading to CCS determination in better agreement with quantum chemistry predictions.

Asthma is a respiratory disease characterized by chronic airway inflammation which can lead, if not correctly managed, to tissue remodeling associated with an irreversible decline in lung function. Hypersensitivity of the respiratory tract to non-specific stimuli, which causes triggering of asthma attacks, is also observed. Despite medical advances, asthma remains an important socio-economic and public health concern since this condition affects 300 million people and causes more than 300 000 deaths worldwide every year. Furthermore its annual cost is estimated at over 30 billion euros in Europe. These issues can be partially linked to an inadequate control of asthma due to undesirable effects of existing medication such as corticosteroids. Hence, the development of new medications with improved effectiveness and reduced adverse effects could allow a better management of the disease. It has been recently discovered that inhaled solution of hydroxylpropyl-beta-cyclodextrin (HPBCD) is able to reduce allergen-induced bronchoconstriction in asthmatic patients, with no toxicity observed in healthy patients further to administration. Based on these results, our project seeks to develop new antiasthmatic medication containing an association of HPBCD and budesonide, a widely used corticosteroid in long-term treatment of asthma. Thus, we investigated complexation between the two molecules. Interestingly, it was observed that when budesonide is complexed with HPBCD, its permeability across a Calu-3 cell layer is reduced. Several experiments in mouse models confirmed that HPBCD acts as a sustained delivery system which progressively releases budesonide into the lung parenchyma, leading to a prolonged anti-inflammatory effect. Due to high Peclet number of HPBCD, the spray dried complex exhibited wrinkled particles whose interest in dry powder for inhalation is well known. Thanks to its anti-inflammatory effect and its sustained release potential, HPBCD could significantly reduce corticosteroids needed doses for management of asthma. However, a clinical study has to be performed to determine the optimal budesonide/HPBCD ratio and the minimal effective dose of complex. Further investigations are also needed to exploit the potential of spray dried HPBCD and develop a powder for inhalation by particle engineering. [less ▲]

Atomic theory is a key concept in science education. However, it was found that students often have difficulties in learning the fundamental notions of this theory. These difficulties reveal themselves in the expression of some preconceptions which tend to persist over time and thus may occur up to the higher education level. The goal of our study is to highlight some difficulties related to the notions of models and modelling notions and to illustrate the causes of appearance of such preconceptions. To do this, two questionnaires were submitted to future sciences teachers (chemistry, biology and physics) who did a training at the University of Belgium in 2014-2015 and in 2015-2016 (40> participants). The first questionnaire deals with the modelling concept and process while the second one is about the atomic model diagrams which illustrate many textbooks. Identifying the nature of the models and their construction may lead to misconceptions while acquiring basic scientific knowledge. [less ▲]

Die Möglichkeit, seit Ende des 19. Jahrhunderts Klänge elektronisch zu produzieren und zu reproduzieren, hat die Wahrnehmung für die Materialität von Musik im Laufe des 20. Jahrhunderts immer weiter geschärft. Durch neue Studiotechniken wurde der Klang sicht- und greifbar gemacht, konnte zerschnitten und abgemischt werden. Autoren der Beat Generation eigneten sich diese Möglichkeiten an und versuchten sie, auf das Textmaterial anzuwenden. Doch was geschieht genau, wenn Literatur elektrifiziert wird? Der Untersuchung dienen deutsche und französische Werke seit den 1980er Jahren, Werke von Rainald Goetz (Irre, Rave) und Virginie Despentes (Bye bye Blondie, Vernon Subutex), die neuere Entwicklungen der „electronic revolution“ (W.S. Burroughs) hervorheben. Beide Autoren bedienen sich der Nähe zur Musik um neue Kompositionsprinzipien, Raumgestaltungen und Figurenkonstellationen zu entwerfen, die in den jüngsten Werken – entgegen den Anfängen der Popliteratur – auch politische Stellungnahmen zum Umgang mit Rauschen und Geräusch skizzieren.

Perineuronal nets (PNNs) are aggregations of extracellular matrix components surrounding the soma of some neurons, mainly GABAergic interneurons expressing the calcium binding protein parvalbumin (PV+). In mammals, the development of PNNs limits synaptogenesis around PV+ neurons and PNNs have been validated as a marker characterizing the end of critical periods for some types of learning. In oscines, song learning is limited to critical periods either during ontogeny in close-ended learners such as zebra finches or during specific phases of the annual cycle in open-ended learners such as canaries or starlings. In zebra finches, PNN expression increases when the song crystalizes and this increase is markedly inhibited if juveniles are deprived from a tutor, which is known to delay the closure of the critical period for song learning. Nothing is known however about a possible role of PNNs in adult seasonal plasticity of open-ended learners. We compared PNNs expression and their colocalization with PV+ neurons in photosensitive, photostimulated, and photorefractory starlings. Although this treatment affected as expected the testes volumes, testosterone concentrations and volumes of song control nuclei, it did not markedly change the expression of PNNs or PV+ neurons in song control or auditory nuclei. In a second experiment, brains of female canaries implanted with testosterone for 1, 2, 9, or 21 days displayed an increase of the total numbers of PV+ neurons and PNNs in HVC, the total number of PNNs in nucleus robustusarcopallialis (RA), the density of PNNs in Area X and the %PV+ neurons surrounded by PNNs in RA and Area X. Interestingly the density of PNNs in song control nuclei progressively decreases from zebra finches to canaries to starlings in parallel with the increased song plasticity in these species supporting the notion that PNNs may limit brain and thus song plasticity in a species-typical manner.

In the univariate context, coefficients of variation (CV) are widely used to compare the dispersion of a variable in several populations. When the comparison is based on p characteristics however, side-by-side comparison of marginal CV’s may lead to contradictions. In this talk, we present a multivariate coefficient of variation (MCV), defined as the inverse of the Mahalanobis distance between the mean and the origin, whose usefulness is demonstrated in some applications in finance and analytical chemistry. A full inference toolbox is provided for practitioners: several parametric and non-parametric bias-correction methods are suggested and compared, and some exact and approximate confidence intervals are built and analyzed in a simulation study. Finally, in order to meet the practical need to compare MCV’s in K populations, some asymptotic statistical testing procedures are derived, whose finite-sample performance is empirically assessed. Throughout the talk, the robustness of the techniques will be discussed. As a by-product, a test statistic allowing to reliably compare K univariate CV’s even in presence of outliers will be outlined. [less ▲]

We report here the cases of uncommon-shaped crystals in patient's urine. The first one is a 73years-old man with massive crystalluria observed in his microscopic urinalysis on Sedimax° (Menarini). Observed crystals had various shape (needle, stick, Feather...). The patient was hospitalized because of lactic acidosis due to suicide attempt by medication overdose. The following medication had been taken: prazepam, acetaminophen, tramadol and Triumeq°, a new anti-retroviral association of dolutegravir, abacavir and lamivudine. Infrared analysis of dryed urine didn"t allow to identify any common stone component, nor any medication. We further discuss about the possible implication of dolutegravir in crystalluria in this patient. Secondly, we show several N-acetylsulfamethoxazol (sulfamethoxazol metabolite) urine crystals detected in microscopic urinalysis of various patients. All had uncommon shape and were sometimes associated to acute kidney injury [less ▲]
