Orange Flowers and Incense to the Glory of the King in the French Festivals of 1622 The communication explores the way in which the festival apparatus establishes a sacred dimension in the ordinary space and time of the city. We consider the immaterial devices of the spectacular apparatus: light, sound, with special attention to the smell, its iconic power and liturgical significance. The study is conducted on the iconographic and textual descriptions of two kind of celebrations which took place during the summer and autumn of 1622 in France: Louis’s triumphal entries following his victories against the Protestant rebels, and the solemnities for canonization of Jesuits Ignatius of Loyola and Francis Xavier, miles of catholic faith between Europe and Asia. In this historical perspective where sacred/secular points converge, these festivals contribute to shape the imago gloriae on the urban space through the ephemeral language of festival and its indelible poli-sensory effect on audience’s memory.

The aim of the present study is to build a mathematical model of the respiratory system connected to an extracorporeal CO2 removal device (ECCO2RD) to optimize the gas exchanges efficiency. The model must be simple enough to provide rapid solutions and to estimate specific parameters from available clinical data. But it also must be complex enough to be able to simulate the respiratory system when protective ventilation is used and when this system is assisted by an ECCO2RD. [less ▲]

Notre objectif est de discuter des diagnostics du fonctionnement psychologique pervers et de la personnalité psychopathique. Si les versions récentes du DSM (IV et 5) ignorent ces diagnostics, la pratique clinique suggère de conserver ces deux entités présentant une finesse psychopathologique plus grande et un pouvoir discriminatif plus important que la personnalité antisociale. Nous souhaitons interroger les dimensions intrinsèquement adaptatives de ces deux entités, mais aussi relever leurs différences sur le continuum de l’adaptation. Nous chercherons, en effet, à démontrer que le principe d'adaptation est une dimension centrale et commune aux deux entités, mais qui « se joue » de façons différentes pour chacune. Le pervers est hyper-adapté à son interlocuteur tout en présentant des moments paradoxaux d'inadaptation. Le psychopathe, avec sa faculté de chosification de l'alter ego et ses compétences émotionnelles paradoxales, présente une adaptation plus solitaire. Dans une perspective inspirée des paradigmes éthologique et phénoménologique, nous tenterons de cerner les différences essentielles entre ces deux modes d’être-au-monde. [less ▲]

In a world where the electricity prices become more and more volatile, notably due to renewable energies, the industry is suffering from cost variations never seen before, especially when electro-intensive. Nevertheless, the plants can significantly reduce this impact: some electro-intensive factories could shift their production to time periods where the electricity is cheaper, resulting in large savings. At the same time, the grid operator can remunerate this consumption adaptation as a flexibility service. Our research goal is to optimise the operations of a factory around this flexibility. We compute a production plan that adapts to price forecasts, but also flexibility levers that adjust this plan to react to unexpected price changes. We propose the unifying concept of reservoir to provide sufficiently good models for the plant's processes. Nevertheless, this methodology implies to have frequent production plan changes, which directly impacts the workers, as they may be asked to follow barely predictable schedules. This has a significant detrimental effect on their quality of life. As a consequence, the human aspect of flexibility must also be considered: we seek for production plans that consider both workforce and energy costs, and we then assign workers to work shifts while ensuring their well-being. This HR orientation is the most innovative contribution of this research project. [less ▲]

What strategies do migrants living in European cities use to challenge inequalities in access to healthcare, participation in the labor market and the creation of social support networks? The papers in this panel aim to respond to this question by drawing from transnational and intersectional approaches conceptualizing inequalities as sets of relationships between people and broader structures in which interactions generate better opportunity for some more than for others (Tilly, 2000). Panel participants consider that these interactions and the benefits that can be obtained through migration are affected by various social categories such as gender, class, sexual identity, transnational connections, and citizenship. Intersectional approaches allow to examine how these axes of inequality (Crenshaw, 1989; Anthias, 2001) simultaneously affect migration outcomes and also how they operate differently according to the geographical space in which they develop: origin and host societies as well as transnationally. Nonetheless, the papers presented in this panel will also emphasize migrants’ agency to resist or conform to the inequalities they face. Overall, this panel aims to contribute to the study of migration and inequality at the conceptual and methodological levels. At the theoretical level, the panel will build on new debates on the reproduction of intersectional inequalities in transnational settings (Faist, 2016, Amelina, 2017). At the methodological level, all paper presenters have use multi-sited ethnographic methods (working in cities such as Madrid, London, Milan, Brussels and Frankfurt) and will therefore use the panel as an opportunity to discuss the strengths and weaknesses of such method.

De nombreux programmes thérapeutiques recommandent d’orienter la thérapie sur la reconnaissance du trouble ou de la maladie. Nous évoquerons cette problématique dans le cadre de la psychiatrie légale (particulièrement avec des patients présentant un diagnostic de schizophrénie et ayant commis des faits de délinquance sexuelle). Avoir pour objectif de réduire l’anosognosie pose la question des représentations du trouble et de la connaissance de ces phénomènes complexes. La distinction des perspectives en première et troisième personnes est un apport récent et décisif de la phénoménologie à la psychologie clinique et à la psychopathologie (Parnas, Sass & Zahavi, 2012). La perspective en troisième personne consiste en l’attribution, depuis une position externe, de signes cliniques repérés indépendamment du ressenti exprimé par le patient. L’exemple typique de ces signes est le délire et l’hallucination du schizophrène. Ces symptômes cristallisent précisément les difficultés qu’éprouve le sujet à se reconnaitre affecté du trouble. La perspective en première personne concentre, quant à elle, son attention sur l’expérience subjective exprimée par le patient. Si l’on reprend le cas de la schizophrénie, ce sont la « perte de l’évidence naturelle » des choses ou un « sentiment de diminution du soi » qui sont verbalisés. Ce pas de côté de la vision omnisciente du médical, assumant une remise en cause du pouvoir de domination qu’entraine la perspective en troisième personne, se révèle être un outil psychothérapeutique pertinent. Il désacralise le problème de l’anosognosie et ouvre la voie à une perspective intersubjective, à une « co-reconnaissance ». [less ▲]

Detailed topographic data have become widely available for inundation mapping. While the use of such high-resolution data enables the computation of flow variables at a fine scale, the computation time remains too high for many practical applications. In contrast, models solving the shallow-water equations with porosity provide a useful tool to improve the computational efficiency, while preserving to some extent the detailed topographic information through porosity parameters. In this study, we present a new model solving the fully dynamic shallow water equations with anisotropic porosity based on Cartesian grids. Using a Cartesian grid leads to specific challenges, particularly as regards the definition of the conveyance porosities at the cell edges. Moreover, the presented model is further improved by a merging method so as to increase the computational efficiency without affecting the overall accuracy. The performance of the model has been evaluated based on a wide range of test cases, which confirm the validity of the model and the benefits of such a modelling framework. [less ▲]

During service encounters, customer contact employees often need to deliver bad news: unexpected information contrary to the customer’s wellbeing. For example, technicians regularly tell customers that none of the data on their computer hard drive can be retrieved, veterinarians often inform owners that a beloved pet has cancer and cannot be cured, and airline staff regularly tell travelers that their flights have been cancelled due to bad weather. For some customer-contact employees, delivering bad news is an unavoidable, delicate, and emotionally-charged task that occurs regularly. Disclosing bad news can be highly stressful and perhaps detrimental for (1) customers, (2) customer- contact employees, and (3) service firms in general. Accordingly, it is crucial for service organizations to better understand bad news encounters (i.e., situations during which customer contact employees must deliver negative information) to better equip their managers and employees to deliver such news to customers. The topic of how to best deliver bad news has been broached in various disciplines, including the medical literature (e.g., Baile et al. 2000, 2002; Rosenbaum et al. 2004), the management literature (e.g., Bies 2013; Kothari, Shu, and Wysocki 2009), and the sociology literature (e.g., Clark and LaBeff 1986). These literatures have (1) examined the attitudes and emotions of the discloser of extreme bad news in very specific contexts, (2) identified the tactics used by disclosers, and (3) developed protocols for delivering extremely negative information. Surprisingly, studies of bad news delivered by contact employees are scarce in service research. Service failure and service recovery have received much attention, but this literature has two major gaps when it comes to understanding the delivery of negative information. First, service recovery research generally skips over the initial part of the process where employees first communicate bad news to customers, and instead focuses primarily on the process involved to resolve the situation. Second, there are many situations in which employees must deliver negative information to customers where it is clear that a service failure has not occurred (e.g., informing a customer that his 30-year old dishwasher is beyond repair). We use the critical incident technique (CIT) (Flanagan 1954; Gremler 2004) to analyze 200 incidents where service employees from a wide range of service sectors had to deliver bad news to a customer.

Despite low crude oil prices and the increasing access to shale gas, the establishment of a biobased economy remains a worldwide priority. An integrated biobased economy would not only consider renewable biobased resources to provide industrially relevant chemicals, but would also redefine chemical processing by using greener, safer and more selective process technologies. The last few decades have witnessed the emergence of promising alternative energy sources such as microwave irradiation and alternative process technology such as continuous-flow reactors. Even if biobased chemicals are still marginal on the marklet compared to petrochemicals, many biorefineries are now able to convert biomass into biobased chemical building blocks of good purity on large scales. Amongst these products, glycerol – a side product of the biodiesel industry – is a particularly appealing chemical platform thanks to its high functionality and its wide availability. Various high-value added chemicals can be obtained from glycerol, among which glycerol carbonate retained our attention. Glycerol carbonate is an attractive glycerol derivative that can be used in many applications ranging from low-VOC solvent to polymer synthesis. Many publications describe its synthesis using different catalysts or alternative activation methods such as microwave. Our research effort in process intensification for the industrial valorization of biomass led us to develop an intensified carbonation process of glycerol under microwave irradiation, affording an unprecedented reactivity with short reaction times and high selectivity towards glycerol carbonate. Based on this preliminary study, and using the microwave-to-flow paradigm, continuous-flow processes using mesofluidic reactors have been developed to obtain glycerol carbonate in good yield and high purity.

L'objectif de cette communication consiste à dégager les caractéristiques normatives de la conscience émue. Nous mobiliserons pour ce faire la thématique des "impératifs affectifs", qui est abondamment discutée par Sartre dans "Les Racines de l'éthique". Sur cette base, nous développerons une réflexion en trois temps. 1° Nous situerons tout d'abord les "Racines de l'éthique" dans la continuité des réflexions de "l'Esquisse d'une théorie des émotions". 2° Nous montrerons ensuite que l'analyse des impératifs affectifs enveloppe une critique du positivisme, qui est une approche massivement adoptée par nombre de philosophie des émotions. 3° Enfin, nous approfondirons la description sartrienne des impératifs affectifs à partir de "L'Émile" de Jean-Jacques Rousseau. L'association de l'un et l'autre texte nous permettra en effet de commenter la "seconde forme d'émotion" qui est très allusivement décrite par les dernières pages de l'Esquisse d'une théorie des émotions. Plus largement, ce détour par la philosophie politique des modernes permettra d'établir un dialogue entre la phénoménologie sartrienne de l'affectivité et l'approche de la normativité qui est proposée par la philosophie française des sciences sociales.

The existing literature in fire engineering is mostly based on single component study of structures, as opposed to system level building performance. In current practice, fire does not need to be considered as part of the structural design of the building. The required fire protection for steel components in a building is based on prescriptive design guidelines, which are based on standard fire tests on individual structural members. In addition, the fire-structure engineering has primary focused on deterministic analysis, while the field is moving towards performance-based design in recent years. Meanwhile, the scenarios leading to a fire event and the performance of the structure at elevated temperatures involve a great level of uncertainty. This work focuses on fire-structure interaction with the objective of developing fire fragility functions that capture fire damage uncertainty for the entire building (i.e., at the system-level). A fragility function provides the probability of exceeding a damage state for a given intensity measure of a given hazard. Fire fragility functions can be developed to measure the expected losses based on performance of a building structural system, rather than a single component. Different functions can be developed for buildings with different typologies (e.g. high-rise steel building with moment resisting frame, low rise steel building with bracing). This presentation derives fragility functions based on stochastic analyses of prototype buildings. In developing the fragility functions, uncertainties in the fire model, the heat transfer model and the thermo-mechanical response should be considered; but such a large number of random variables adds to the complexity of analysis and the computational time. Based on a sensitivity analysis for steel gravity frames, this work identifies the most important input parameters to be considered as random variables when developing fire fragility functions for an entire building. The sensitivity analysis for a multi-story steel building prototype is completed considering uncertainties at the compartment and building levels. At the compartment level, uncertainty in the fire scenario, compartment geometry, applied load, thermal and mechanical properties of steel and insulating materials are considered. At the building level, the influence of fire-resistance rating, building height, and occupancy type are studied. The results of this study identify the local and global parameters needed as part of deriving system-level fire fragility functions for a steel building. [less ▲]

Urban flood risk is influenced by many factors such as hydro-meteorological drivers, existing drainage systems as well as vulnerability of population and assets. The urban fabric itself has also a complex influence on inundation flows. In this research, we performed a systematic analysis on how various characteristics of urban patterns control inundation flow within the urban area and upstream of it. An urban generator tool was used to generate over 2,250 synthetic urban networks of 1 km². This tool is based on the procedural modelling presented by Parish and Müller (2001) which was adapted to generate a broader variety of urban networks. Nine input parameters were used to control the urban geometry. Three of them define the average length, orientation and curvature of the streets. Two orthogonal major roads, for which the width constitutes the fourth input parameter, work as constraints to generate the urban network. The width of secondary streets is given by the fifth input parameter. Each parcel generated by the street network based on a parcel mean area parameter can be either a park or a building parcel depending on the park ratio parameter. Three setback parameters constraint the exact location of the building whithin a building parcel. For each of synthetic urban network, detailed two-dimensional inundation maps were computed with a hydraulic model. The computational efficiency was enhanced by means of a porosity model. This enables the use of a coarser computational grid , while preserving information on the detailed geometry of the urban network (Sanders et al. 2008). These porosity parameters reflect not only the void fraction, which influences the storage capacity of the urban area, but also the influence of buildings on flow conveyance (dynamic effects). A sensitivity analysis was performed based on the inundation maps to highlight the respective impact of each input parameter characteristizing the urban networks. The findings of the study pinpoint which properties of urban networks have a major influence on urban inundation flow, enabling better informed flood-proof urban design. [less ▲]

Uncertainties in sea-level rise projections are mostly due to uncertainties in Antarctic ice-sheet predictions (IPCC AR5 report, 2013), because key parameters related to the current state of the Antarctic ice sheet (e.g. sub-ice- shelf melting) and future climate forcing are poorly constrained. Here, we propose to improve the predictions of Antarctic ice-sheet behaviour using new uncertainty quantification methods. As opposed to ensemble modelling (Bindschadler et al., 2013) which provides a rather limited view on input and output dispersion, new stochastic methods (Le Maître and Knio, 2010) can provide deeper insight into the impact of uncertainties on complex system behaviour. Such stochastic methods usually begin with deducing a probabilistic description of input parameter uncertainties from the available data. Then, the impact of these input parameter uncertainties on output quantities is assessed by estimating the probability distribution of the outputs by means of uncertainty propagation methods such as Monte Carlo methods or stochastic expansion methods. The use of such uncertainty propagation methods in glaciology may be computationally costly because of the high computational complexity of ice-sheet models. This challenge emphasises the importance of developing reliable and computationally efficient ice-sheet models such as the f.ETISh ice-sheet model (Pattyn, 2015), a new fast thermomechanical coupled ice sheet/ice shelf model capable of handling complex and critical processes such as the marine ice-sheet instability mechanism. Here, we apply these methods to investigate the role of uncertainties in sub-ice-shelf melting, calving rates and climate projections in assessing Antarctic contribution to sea-level rise for the next centuries using the f.ETISh model. We detail the methods and show results that provide nominal values and uncertainty bounds for future sea- level rise as a reflection of the impact of the input parameter uncertainties under consideration, as well as a ranking of the input parameter uncertainties in the order of the significance of their contribution to uncertainty in future sea-level rise. In addition, we discuss how limitations posed by the available information (poorly constrained data) pose challenges that motivate our current research. [less ▲]

En 2006, l’écrivain et essayiste allemand Hans Magnus Enzensberger publie Le perdant radical, un « essai sur les hommes de la terreur », conformément au sous-titre de cet ouvrage d’une soixantaine de pages dans lequel l’auteur décrit les multiples facettes d’un ensemble de figures meurtrières. Du tireur fou dans un lycée américain au combattant islamiste ceinturé d’explosifs, isolé ou organisé en groupe, tout perdant radical répond au même mécanisme : c’est « lorsqu’il aura repris à son compte le jugement des autres, ceux qu’il tient pour les gagnants (…) qu’il pète les plombs. » L’indistinction est frappante : pour Enzensberger, le perdant radical peut sévir seul ou en groupe ; son moteur profond, irréductible à un engagement politique ou religieux, reste le même dans les deux cas. Car pour l’essayiste, rien, pas même une théorie critique de la société, ne permet de rendre compte de la nature du perdant radical, si ce n’est la suppression de l’instinct de conservation. Dans plusieurs textes littéraires – on songe notamment à son poème Zur Frage der Bedürfnisse (1991) et à son entretien autobiographique fictif avec lui-même Erinnerungen an einen Tumult (2014) –, Hans Magnus Enzensberger crée ou recrée des figures de terroristes qui réalisent parfaitement le profil type du perdant radical. Andreas Baader, les jeunes bourgeois d’une secte marxiste en Suède, un terroriste islamiste en fuite, un guérillero sud-américain qui a perdu tout sens de la réalité, autant de figures fictionnelles ou refictionnalisées qui, partant d’une même position d’échec apparemment imposée de l’extérieur et assumée en tant que telle, superposent destruction et autodestruction. L’hypothèse générale à laquelle nous voudrions soumettre ces personnages de terroristes est qu’ils sont les héritiers d’une figure essentielle pour la littérature allemande et anglo-saxonne : l’amok.

Antarctica currently undergoes strong and contrasted impacts linked with climate change. While the West Antarctic Peninsula is one of the most rapidly warming regions in the world, resulting in sea ice cover decrease, the sea ice cover of East Antarctica unexpectedly tends to increase, possibly in relation with changes in atmospheric circulation. Sea ice is a major environmental driver in Antarctica, and changes in sea ice cover are likely to influence benthic food web structure through several processes (modifications of benthic-pelagic coupling, disruption of benthic production and/or modifications of benthic community structure and therefore resource availability for benthic consumers). To date, regions where sea ice cover is decreasing have received more attention than regions where it is increasing. Here, on the other hand, we studied shallow (0-20 m) benthic food web structure on the coasts of Petrels Island (Adélie Land, East Antarctica) during an event of unusually high spatial and temporal (two successive austral summers without seasonal break-up) sea ice cover. Using time-tested integrative trophic markers (stable isotope ratios of carbon, nitrogen and sulfur) and state-of-the-art data analysis tools (bayesian ecological models), we studied the structure of the food web associated to benthic macroinvertebrates communities. In total, 28 macroinvertebrate taxa spanning most present animal groups (sponges, sea anemones, nemerteans, nematods, sipunculids, sessile and mobile polychaetes, gastropods, bivalves, pycnogonids, crustaceans, sea stars, sea urchins, brittle stars and sea cucumbers) and functional guilds (grazers, deposit feeders, filter feeders, predators, scavengers) were investigated. Our results indicate that the absence of seasonal sea ice breakup deeply influences coastal benthic food webs in Antarctica. We recorded marked differences from literature data, both in terms of horizontal (i.e. primary producers and resources supporting animal populations) and vertical (i.e. trophic level of the studied consumers) structure of the food web. Overall, sympagic (sea-ice associated) algae dominated the diet of many important consumers, and the trophic levels of invertebrates were low, suggesting omnivore consumers relied less on predation and/or scavenging than in normal environmental conditions. Surprisingly, few animals seemed to feed on the extremely abundant benthic biofilm, whose exceptional development was also presumably linked with the peculiar sea ice conditions. Interpretation of data was complicated by the peculiar ecophysiological features of Antarctic invertebrates, whose very low metabolic rates could be associated to low tissue turnover. However, comparison of data obtained in the austral summers of 2013-2014 (first year without seasonal breakup) and 2014-2015 (second year without seasonal breakup) clearly showed that the observed trends were linked with actual temporal changes in invertebrate feeding habits rather than with other potential ecological drivers. Our results provide insights about how Antarctic benthic consumers, which have evolved in an extremely stable environment, might adapt their feeding habits in response to sudden man-driven changes in environmental conditions and trophic resource availability. They also show that local and/or global trends of sea ice increase in Antarctica could cause strong changes in food web structure and therefore impact zoobenthic communities. This reinforces the view that, no matter their overall direction (i.e. increase or decrease), fluctuations in sea ice cover are likely to influence Antarctic benthic ecosystems' structure and functioning.

Use of Information Technologies in Egyptology can be traced back to the early 1960s, when first efforts were made in documenting Meroitic scripts or emblematic corpora such as the Pyramid Texts. With the rise of the Digital Humanities in the mid-2000s, many new academic projects that implement IT solutions not only as a way to manage and present data, but also to produce, process and analyse the material, have come to light in the field. The aim of this paper is to give a survey of current digital projects related to the study of ancient Egyptian and Coptic texts. Our goal is not to be exhaustive, but to discuss the methods and tools that are being used and to describe the variety of scholarly practices. The first set of projects to be examined are those related to digital text editions and annotated corpora (including the types of representation format). Second, the question of how to handle the complex writing systems of Ancient Egypt will be addressed by looking at projects that focus on encoding (Manuel de Codage vs Unicode), on establishing hieroglyphic sign-lists (the Thot-Sign-List), on palaeographical databases and on ways to OCRize original texts efficiently. The issue of interoperability and data sharing will then be investigated through a presentation of several related projects working on a XML/TEI interchange format as well as on digital resources for enabling a Linked Open Data approach to the ancient Egyptian written material (http://thot.philo.ulg.ac.be/). Finally, we will argue in favour of a coherent data model so that encoding of data and metadata is done in the most effective way. [less ▲]

Le dispositif du remembrement-relotissement, aussi appelé « Association Foncière Urbaine » en France, est un outil foncier qui permet de réaménager le maillage parcellaire et les espaces publics. Il a pour finalité de matérialiser un projet urbain et il est associé au transfert à une structure de copropriété des droits de propriété relatifs aux terrains nécessaires à la réalisation du projet en question. Il revient ensuite à cette structure de copropriété de gérer le développement du périmètre. À l’issue de l’aménagement, les propriétaires sont rétribués proportionnellement à la valeur de leurs apports fonciers respectifs. Le remembrement-relotissement est considérée comme une « Belle endormie » de l’aménagement . En effet, alors que ce dispositif présente de nombreux avantages (mobilisation du foncier à faible coût, développement de projets intégrés…), il n’est que très rarement appliqué sur le terrain . C’est dans ce cadre que se situe notre proposition, dont l’objectif est de chercher à comprendre les raisons qui limitent l’usage de cette procédure ainsi que les leviers susceptibles d’enfin banaliser sa pratique. Notre intervention sera structurée en trois parties. En première partie, nous développerons les résultats d’une analyse ayant cherché à comprendre la non-utilisation du dispositif au sein du contexte wallon . Ce travail a mis en avant que le remembrement-relotissement souffre d’une mauvaise image auprès des experts wallons de l’aménagement du territoire. Le problème fondamental réside dans la faible faisabilité liée à l’incapacité de mobiliser de concert un nombre suffisamment élevé de propriétaires. La seconde partie de notre intervention sera consacrée à la situation néerlandaise. Aux Pays-Bas, le remembrement-relotissement n’est pas non plus un outil fréquemment utilisé, ce qui s’explique par la tradition de production foncière publique. En effet, il est inutile de chercher à travailler avec les propriétaires lorsque les collectivités locales sont directement à la manœuvre pour mettre en place les projets de développement. Pour autant, en raison de la crise du modèle néerlandais de la production foncière publique, le remembrement-relotissement est aujourd’hui considéré par les autorités néerlandaises comme un outil très important afin de continuer à contrôler les montages opérationnels tout en limitant l’implication financière des collectivités. Il ressort de la comparaison entre les Pays-Bas et le Wallonie que le différentiel de confiance entre acteurs est une explication fondamentale de l’opposition entre les deux contextes. Dans ce cadre, la troisième partie de notre intervention rendra compte d’une recherche en cours qui vise à objectiver l’impact des cultures d’aménagement sur les montages opérationnels. Ce projet, qui s’appuie sur le champ de l’économie comportementale , vise en particulier à traiter des thématiques de l’aversion face aux risques et de l’importance de la confiance dans le développement des partenariats et des coopérations.

The criterion of 3% of stuttered disfluencies – (part-)word repetitions, sound prolongations and blocks – is often suggested to diagnose the stuttering in children (e.g., Boey et al., 2007; Yairi & Ambrose, 2005). There is a long-lasting debate among scholars about the relevance of considering monosyllabic word repetitions as stuttered disfluencies, given their high frequency in typically developing children (e.g., Howell, 2013; Wingate, 2001). Yet, these are the prime characteristics that prompt identification of early stuttering by parents (Yairi & Ambrose, 2013). Nevertheless, very few normative data exist concerning the disfluencies occurring in the speech of normally fluent children (Tumanova et al., 2014), and none exist in French. The aim of this study is to examine the need for reference data in French in order to distinguish typical developmental disfluency from stuttering. We used the CHAT transcription system and the coding conventions of FluencyBank to transcribe and analyse the speech disfluencies of twenty monolingual, French speaking children who do not stutter, aged 4 years. FluencyBank (Bernstein-Ratner & MacWhinney) is a shared database for the study of the development of fluency in both normal and disordered populations. It is a project of Talkbank that seeks to archive and facilitate sharing of data relevant to fluency research. [less ▲]

Regulation in terms of greenhouse gas emissions becomes more and more stringent and the fuel consumption targets decrease. In order to meet these demands, vehicle electrification has increased over the last decade. With the arrival of plug-in hybrids and battery electric vehicles, efficient battery cooling system becomes a necessity and has to be integrated into the vehicle thermal management. One of the possibility is to integrate a chiller in the air conditioning system for extreme operating points. Moreover, this kind of system can be dedicated to luxury or large passenger cars for which a secondary evaporator is present to guarantee the comfort for rear passengers. The main challenge of this air-conditioning architecture is to maintain simultaneously the cabin thermal comfort via one or two evaporators on one hand and to maintain the battery cells in an ideal temperature range on the other hand.

Membre d’une ancienne famille noble d’origine allemande, le baron Frédéric de Reiffenberg (1795-1850) s’est distingué dans l’histoire de Belgique pour avoir été le premier à occuper le poste de conservateur de la Bibliothèque royale de Belgique, fondée en 1837. S’il doit notamment ce poste à l’appui qu’il reçut d’amis haut placé, il convient de rappeler que la nomination à la direction de cette institution fut pour lui une belle opportunité pour quitter Liège et, plus spécifiquement, la charge de professeur d’histoire du Moyen Âge qu’il occupait à l’Université depuis le 6 décembre 1835. En effet, au cours de l’année 1836, son parcours professionnelle fut entaché d’un scandale sans précédent qui le contraint à démissionner : une accusation de plagiat formulée par l’un de ses éminents collègues, Edouard de Lavalleye (1811-1869).

This presentation focuses on multiple-choice items without any correction or control for guessing. Most often, item responses are recoded as binary outcomes so that dichotomous logistic item response models (such as the 2PL or 3PL models) can be used to estimate ability levels. This is however at the cost of loosing information from collapsing all distractors into a single FALSE category. Polytomous IRT models could be considered to overcome that drawback but none of the classical models are suitable to incorporate guessing into account. The purpose of this talk is to introduce a modification to the graded response model (Samejima, 1969) that can take guessing into account. The modification consists in introducing lower and upper asymptotes to the cumulative probability curves. After a brief theoretical and technical description, practical implementation using the R package mirt (Chalmers, 2012) is discussed. Primary results from a simulation study are eventually presented and compared to traditional IRT scoring methods for scoring multiple-choice items. [less ▲]

En 1916, l’archéologue Vittorio di Cicco entreprenait des fouilles sur le site de la « Vigna Manzi », à Garaguso, en Basilicate. Il y découvrit les vestiges d’un temple qui contenait encore une partie de son mobilier et différentes offrandes dont la statuette en marbre d’une déesse trônante accompagnée d’un tempietto. Cette découverte ramenait à la lumière un site de premier ordre pour l’étude des relations qu’entretenaient, dans ces territoires d’Italie méridionale, les populations indigènes et les Grecs des cités de Grande Grèce. Dans le courant du XXe siècle, d’autres fouilles se sont succédé dans le sanctuaire de la « Vigna Manzi » – sans grand résultat. Durant l’été 2008, l’archéologue Jean-Marc Moret a cherché à identifier l’emplacement de la fouille de Vittorio di Cicco. Ce sondage lui a permis de retrouver d’autres structures monumentales augurant une découverte d’envergure.

Architecture refers to the overall shape of a tree and the spatial position of its components. Tree height determines the position in the forest canopy and access to light, while the amount and spatial distribution of the foliage depend on the depth and the width of the crown. The aim of this study is to understand how tree architecture varies across coexisting tropical tree species and relates to functional traits. Forty five coexisting tree species were sampled in the semi-deciduous forests of Northern Congo. Species were classified according to ecological strategies, specifically regeneration guilds: shade bearers (27 species), non-pioneers light demanding (14 species) and pioneers (4 species). For each species, 14–72 trees (968 trees in total) were measured over a large range of diameter (10–162 cm). At the tree level, we measured the diameter (D in cm), height (H in m), crown radius (Cr in m) and crown depth (Cd in m) and crown exposure index (CEI) was visually estimated. At species level, architectural traits (Dmax, Hmax, Crmax and Cdmax), life history traits (dispersal mode, phenology and guild) and functional traits (wood density and light requirement) were obtained. We investigates the H-D, Cr-D and Cd-D allometric relationships at the tree level using linear mixed models on log-transformed data with species as a random effect on both slope and intercept. We used the multivariate analysis to quantify the relationship between architectural, functional traits and life history traits. Based on AIC, we found that the best linear mixed model was the one with two species random parameters (intercept and slope) for H-D and Cr-D allometries, while the best model for Cd-D allometry was the one with only a random intercept. Thus, our results showed a significant variation in tree allometry between coexisting species. The interspecific variation in H-D allometry was related to light requirement while Cr-D and Cd-D allometries were more related to dispersal mode and wood density, respectively. The confirmed the existence of three ecological strategies (shade bearers, non-pioneers light demanding and pioneers) in tropical forests, specifically in Central Africa. Architectural traits were the main traits that differentiate between ecological strategies. Architectural traits are therefore strong predictors of ecological strategies of coexisting tropical tree species. [less ▲]

In 1960, some architects questionned the « Charte d’Athènes » and its principles. They explored the language of architecture in some Congress and took the name of Team X. During their meeting they tried to take into account the potential of different finding in sciences. The architects of the Team X group who intervened in France where mostly influenced by structuralist apprach of Levi-Strauss an the biologist François Jacob. In his book la logique du vivant , Jacob introduced some concepts, some vocabulary words which inspired architects. These terms, this architectural grammar is : fabric, cells, DNA, 3d structure. Candilis-Wood-Josic were influenced by Jacob’s book and radio conference at that time and did some projects around theses formal analogies. In our point of view, like Jean Renaudie said, biology findings influenced his vision of the society and contributed to question architecture, its forms, its vocabulary. For us, biological analogies following Jean-Pierre Chupin decription, contributed mostly to the development of the neo avant-garde in the 1960’s in France and the different constructions we can see in the french landscape marked the architectural theory and is widely reused nowadays. Through these conference, we want to demonstrate that hypothesis trhough the work of l’Atelier de Montrouge in which Jean Renaudie worked. [less ▲]

If this conference proposes to explore the singular and minor expressions of architectural theory, it could at first seem strange to propose here a paper about the so-called derridean years of architecture. Rather, the vast body of literature produced on this specific episode argues that the encounter of architectural discourses with derridean deconstruction played a major role into the implementation of "the gilded age of theory" (Mallgrave, Goodman, 2011). But such an "age" needs now to be redefined in regard with its own cultural boundaries. What the decon has produced in the Anglo-American field of architectural theory is not what the deconstruction has produced on the French-speaking part of the debate (following the argument of Cusset, 2005). In France, the question of the effects of the Derrida's philosophy on the contemporary architectural discourses and practices still causes a kind of discomfort. "As if" no one could face with what this disciplinary cross-over of the mid-eighties both has produced and has not succeeded in producing; "as if", failure or not, this experimental encounter could had been no effects or consequences on the theories and practices which succeeded it. From one cultural context to another, we have two different versions of a same history. Different but not unrelated. The proposition is here to invest the productive gap between these overlapped versions, in order to question their respective modes of construction but also to re-open their ways of being transmitted. From an original translation of Derrida's Haunt (Wigley, 1993) in French, I would present a methodological approach (Despret, 2001) which attempts to create the conditions of a renewed relation between different versions of what the deconstruction could have produced in architecture. The exercise of the translation is seen as a way to question the co-existence of these different possible versions; a way to slow down the multiple gestures which hastily sweep the hesitations in the shared course of their history.

Tropical forests are important providers of natural resources and ecosystem services but their ecological functions are facing increasing human pressure, linked to economic development. The preservation of tropical forest ecosystems is interrelated with effective land use planning and identification of priority areas for conservation. Initially defined by Greenpeace and the World Resources Institute (WRI) in 2000, Intact Forest Landscapes (IFLs) are large areas of forest minimally impacted by human activities. IFLs were identified by mapping industrial activities, road networks and infrastructure using remote sensing. Since 2014, when IFLs were recognized and adopted by the certification scheme Forest Stewardship Council (FSC), the IFLs have become integrated into forest management policies. In order to trace the history and evaluate the applicability of IFLs for forest management policy in the Central African context, we searched for documents related to the IFL method, and previous similar concepts. The IFL method is simple and cost-effective and enables the monitoring of forest degradation at a global scale. However, the approach mainly considers forest cover and is imprecise at the local scale. For example, hunting, one of the main threats faced by Central African ecosystems, cannot be detected by satellite imagery and is therefore disregarded in IFL identification processes. In contrast, there are other considered anthropogenic activities, such as reduced-impact selective logging, which may be compatible with forest ecosystem conservation. To better tailor the IFL approach to Central African forests, we recommend (i) the consideration of wildlife communities distribution in the analysis of disturbance, (ii) a thorough evaluation of the impacts of different human activities on forest ecosystems, and (iii) the integration of local stakeholders and governments in the design of land management strategies devised to address social, economic and environmental needs.

En 1975, la notion de conservation intégrée est consacrée par la Charte européenne du Patrimoine architectural, adoptée par le Comité des Ministres du Conseil de l’Europe avant d’être solennellement proclamée et développée au Congrès d’Amsterdam (21-25 octobre 1975). Renouvelant fondamentalement les pratiques de rénovation des centres anciens avec l’ambition de créer un dialogue entre aménageurs et conservateurs, cette approche résulte de dix années de réflexions nourries par des échanges entre experts principalement européens, initiés non seulement par le Conseil de l’Europe (Confrontations de Barcelone (1965), Bath (1966), La Haye (1967) et Avignon (1968)), mais également par l’ICOMOS, dès sa fondation en 1965 (Colloques de Cacérès (1965), Tunis (1966), Leningrad et Graz (1969), Lausanne (1973), Rothenburg et Bruges (1975)). Si un regard macroscopique révèle le rôle central joué par Piero Gazzola et Raymond Lemaire, respectivement président et secrétaire général de l’ICOMOS et auteurs, avec François Sorlin, d’une étude de synthèse préalable à la Charte européenne, cette contribution se propose d’augmenter la focale afin de révéler, à travers l’étude des actes des colloques, le rôle des réseaux d’acteurs en présence dans l’élaboration de la nouvelle politique.

Fundamental motor patterns are prerequisites to specific motor/sports skills and a determinant of the involvement in physical activity. Several tools have been developed in order to measure motor development in children. Each test battery presents its own characteristics. MOBAK-1 focuses on two categories of basic motor competencies in order to record the effects of physical education (PE) at the elementary school level. That tool proposed 8 tests. For each of them, pupils receive point scores (0–2 points) according to the quality of their performance. MOBAK-1 is supposed to be used by PE teachers but there is still a lack of data about this, justifying the present study. We trained 7 PE teachers (4 males) and analysed the way they implemented the tests in their classes (1st and 2d grades – 6-8 year-old pupils). The training comprised a description of the tests with video examples of the expected movements and common errors, and an analysis of the reliability of the teachers evaluating pupils’ performances showed on video (at least 10 trials). A participating observation and a short interview were planned to analyse the evaluation process of each PE teacher. Catching and Rolling reached the reliability requirements within the first 10 trials while 15 to 16 videos were necessary for the six other tests. Two teachers seemed to have more difficulties that could be related to their lack of experience (P1) or a potential lower interest (P7). Before implementing the test with their classes, all teachers read again the guidelines. The majority was really satisfied by the information provided by the researchers (3.86/4) and confident about how to manage the evaluation (3.57/4). Five teachers worked alone and 4 were able to evaluate one class/lesson. All teachers developed specific strategies in order to save time. Several practical recommendations have been proposed.

School is a privileged place for evaluating children’s physical and motor competencies. Tests are often used for educational and/or research purposes. Adults collect the data but do not verify how children experience these evaluations that can be perceived as difficult moments. Even if they are supposed to motivate pupils, they can decrease the self-perception and limit the participation. Several test batteries have been developed in order to measure motor development of young children (M-ABC, KTK, TGMD …). They are based on the assessment of performances. On the other hand, MOBAK-1 has been developed in order to verify if some motor competencies are mastered or not. To our knowledge, no study tried to determine how the pupils passing these tests feel about their experience. This study focused on that original topic. Seven primary school PE teachers administrated the MOBAK-1 tests to their classes (149 1st and 2d grades – 6-8 year-old). After the tests, pupils fulfilled an adapted questionnaire based on pictograms designed to facilitate pupils’ understanding. The most important finding is that 80.5% of the pupils answered that they loved doing the tests. Only 3 pupils expressed a negative opinion. As pointed out by the correlation between the real achievement mean scores and the perceived competence mean score for each test (r= 0.90), pupil’s self-assessment seemed appropriate. The correlation between the perceived competence and appraisal of the tests is lower (r=0.59). The gamelike status of some tests would be more determinant for their appraisal by the pupils than their level of achievement: balancing is definitely the most appreciated test (35.6% of the pupils selected it). In the same way, even if the achievement level is not high, throwing is relatively well appreciated. Trying to touch a target with a ball is funny. On the other hand, jumping and bouncing were ‘less’ appreciated. [less ▲]

Une enquête interne au sein du département de Physique de l’Université de Liège (Belgique) a révélé que les assistants en charge des travaux pratiques considéraient importante l’aide qu’ils apportent aux étudiants en laboratoire. Malgré cela, les assistants sondés considèrent que les étudiants sont insuffisamment motivés lors de leur arrivée et observent un manque d’investissement dans la tâche au cours de ces laboratoires. En réponse à ces constats, un projet a été développé afin de tenter de faciliter la compréhension de la matière par les étudiants et d’accroître leur motivation à s’investir davantage dans leur formation, et en particulier, lors des travaux pratiques de physique. Basé sur le principe de la classe inversée, ce projet consiste en la réalisation de courtes séquences vidéo introductives aux travaux pratiques. Elles ont notamment pour objectif de présenter la matière sous une autre forme que celle utilisée lors des cours en classe. Concrètement, une première séquence est publiée quelques jours avant le laboratoire. Les concepts de base y sont illustrés et rapidement mis en application. Les étudiants sont alors invités à commenter une application particulière et non expliquée. Quelques jours plus tard, une seconde séquence vidéo est postée. Elle comprend la solution au problème et la présentation du matériel de laboratoire. Ces vidéos ont été conçues en accord avec les standards pédagogiques en la matière au niveau de la durée, de la distribution de la charge cognitive et des principes du multimédia. Une attention particulière a été apportée afin de rendre signifiante la matière enseignée au public particulier auquel elles s’adressent. Enfin, un test formatif composé de QCM permet à l’étudiant de s’auto-évaluer avant le laboratoire. Une analyse portant sur une éventuelle augmentation des notes obtenues aux questions en rapport avec ces deux laboratoires et sur la satisfaction des étudiants et des assistants sera effectuée.

Gail Jones’s short story “The Ocean” was published in 2013 as part of an anthology edited by Thomas Keneally and Rosie Scott. Entitled A Country Too Far: Writings on Asylum Seekers, this anthology aimed to ask “some of [the] most admired Australian writers to bring a different perspective and depth to the public debate on asylum seekers”. With “The Ocean”, Jones takes up the challenge quite successfully and, I may also add, quite literally or meta-discursively. The short story’s two interwoven narratives are articulated following an ebb-and-flow movement that enhances the text’s play with the notions of liquidity and time. This is reminiscent of French philosopher Michel Serres’s view of time as made of counter-currents, undertows and turbulences. These liquid folds allow for originally distant points – with no link whatsoever – to become close, superimposed. This then creates an effect of strangeness which Jones cultivates, as when she claims that, since “we’re always in a forward-backward rhythm, not often fully here in the present moment” and “our present is inflected and intercepted by the past and the future, pleated and folded,” this means that, “if we were to see our contemporary world with the eyes of the future, we might see it suddenly aestheticized and made endearingly strange”. By focusing on Jones’s play with perspectives, her narrativisation of folds, and the intertextual link with Primo Levi’s The Drowned and the Saved, my paper will seek to investigate how Jones’s writing not only claims an ethical and moral dimension but also takes up a political stance: it is by writing from multiple perspectives and thus forging unexpected connections, allowing people of different backgrounds, cultures and religions to interconnect, that Jones voices resistance to the narrow-mindedness of those who are privileged in today’s world-wide migration crisis.

Depuis septembre 2012, en Fédération Wallonie-Bruxelles de Belgique, les étudiants inscrits en première année de bachelier en médecine sont interrogés sous forme de questions à choix multiples lors des épreuves certificatives des cours scientifiques donnés au premier quadrimestre de leurs études. Au Département de Physique de l’Université de Liège, les questions des examens antérieurs sont répertoriées, et éventuellement améliorées, afin d’être réutilisées dans le cadre d’un outil d’entraînement en ligne, appelé « simulateur d’examens » (Marique, 2015). Cet outil est destiné à améliorer des connaissances directement en lien avec une stimulation constante de la mémoire des étudiants à l’aide de QCM. Les questions sont analysées de 2 façons différentes : d’une part sur base des résultats des étudiants lors de l’examen (indice de facilité P et P’ et indices de discrimination B et D) et d’autre part, par une évaluation effectuée par les membres de l’équipe pédagogique. Ceux-ci attribuent un niveau de difficulté à chaque question en fonction de 4 critères empiriques : abstraction, réflexion, mixité, mathématiques. Chaque évaluateur attribue une note de 1 à 3 à chacun des critères. La somme obtenue indiquera le niveau de difficulté total de la question selon une règle simple. A l’avenir, dans une perspective d’amélioration du classement par niveau des questions disponibles dans le simulateur d’examens, la concordance entre l’indice P’ et le niveau de difficulté qui lui a été attribué par l’équipe pédagogique, sera étudiée. L’impact de ce système sur l’apprentissage des étudiants fait actuellement l’objet d’un suivi particulier et précis. Toutes les tentatives des étudiants et leurs résultats sont enregistrés systématiquement en prévision d’une analyse des effets de ce système. [less ▲]

Cette communication exposera le dispositif mis en place dans le cadre d’une formation d’enseignants du secondaire supérieur en psychologie et sciences de l’éducation pour amener les étudiants à s’autoévaluer sur la base d’une autoscopie. Ces futurs agrégés effectuent des stages dans l’enseignement général ainsi que dans l’enseignement professionnalisant. Au-delà de la préparation et de la phase active de la pratique enseignante, il est indispensable pour les futurs enseignants (FE) de prendre du recul et d’évaluer leurs pratiques lors d’une phase post active. Afin de les soutenir dans cette démarche exigeante et non intuitive, les formatrices proposent un dispositif aux FE (Inspiré d’un dispositif organisé par l’équipe de Hindryckx MN. dans le cadre de la formation initiale des futurs enseignants du secondaire supérieur en biologie à l’Université de Liège). Celui-ci se décline en plusieurs phases soutenues par différents outils. Lors de deux des trois stages d’enseignement effectués, les futurs enseignants (FE) doivent se filmer en action lors d’une leçon de leur choix (avec l’appui logistique de leur « maitre de stage »). En effet, l’autoscopie, qui correspond à la démarche au cours de laquelle les FE se confrontent aux traces vidéoscopées de leur pratique (Beckers et Leroy, 2011), permet de poursuivre plusieurs objectifs : se (perce) voir en action pour prendre conscience de soi ; analyser et évaluer son propre comportement ; se transformer pour parvenir à une plus grande efficacité et satisfaction de soi (Peraya, 1990). Suite à la leçon filmée, les FE sont invités à procéder à une autoévaluation de leur pratique en plusieurs étapes (« retour à chaud », visionnage de la vidéo et analyse d’un moment de l’action soutenue par une démarche structurée et utilisation d’une grille d’autoévaluation des compétences d’enseignant pour permettre une généralisation). L’ensemble de ce processus individuel sera communiqué aux formatrices par le biais des rapports de stage et fera l’objet d’une évaluation et d’un feedback formatif. [less ▲]

Notre communication se centrerait sur les récits de combats singuliers le manuscrit Gerard du Frattre (1525) et dans l'imprimé Gerard d'Euphrate (1549). Alors que Gerard du Frattre est presque exclusivement constitué de scènes de guerre, le texte de 1459 fait se côtoyer aventures guerrières, amoureuses, comiques et merveilleuses. Eu égard à ces divergences structurelles et thématiques, le duel, qui constitue un motif relativement figé et caractéristique du genre épique, se présente comme un lieu d’observation privilégié pour mesurer les particularités stylistiques des deux proses. Malgré son intérêt de premier ordre, la langue littéraire telle qu’elle se développe dans les réécritures du début du XVIe siècle ne retient que rarement l’attention de la critique. Pour lors, nous étudierions les mécanismes linguistiques mis en place pour « faire jouer [...] les stéréotypes d’une tradition littéraire révolue », en nous attachant particulièrement au lexique et aux figures de style des récits d’exploits guerriers dans les deux récits gerardiens.

Certains étudiants peuvent répondre au hasard ou être inattentifs en situation d’examen. Les indices de détection de patrons de réponses inappropriés (person-fit index) sont prometteurs pour détecter ces types de réponse. Nous allons, dans le cadre de cette communication, nous pencher sur le cas de trois indices de détection populaires qui présentent des caractéristiques permettant d’en faciliter l’interprétation : lz, ZU et ZW. Par contre, des études antérieures ont montré que ces trois indices sont fortement affectés par le fait que l’habileté d’un étudiant est estimée plutôt que réelle (Molenaar et Hoijtink, 1990). Snijders (2001) a proposé une version corrigée de l’indice lz (nommée lz*) afin de tenir compte de cette difficulté. De leur côté, Magis, Béland et Raîche (2014) ont corrigé deux autres indices selon l’approche de Snijders (2001) : U* et W*. Il reste cependant à analyser plus en détails le comportement de la famille des indices corrigés, soit, lz*, U* et W*. Pour ce faire, nous effectuons une étude de simulation et une étude des données du test de classement en anglais, langue seconde (TCALS-II). Les résultats démontrent que les indices corrigés lz* et W* sont les plus intéressants à utiliser. De son côté, U* présente des résultats parfois inappropriés, ce qui relance la réflexion sur la pertinence des indices de détection basés sur les carré-moyens non-pondérés. [less ▲]

Lorsque l’on doit évaluer les résultats d’un test à l’aide de questions à choix multiples (QCM), le traitement des réponses au hasard (« guessing ») est un enjeu crucial pour une évaluation fiable et non biaisée de la compétence testée. Divers mécanismes (comme l’application d’une correction pour le guessing) ont été proposées mais ne sont pas exemptes de problèmes méthodologiques. Une approche par modèles de réponses aux items (MRI) est aussi souvent considérée, mais revient à résumer les réponses des QCM en « vrai/faux » et appliquer des modèles dichotomiques (comme le modèle logistique à trois paramètres). Le but de cette présentation est double : (a) mettre en évidence les faiblesses d’une telle approche dichotomique, et (b) présenter une modification d’un modèle de réponses aux items polytomiques qui prend en compte le possible « guessing » des participants. Cette approche a l’avantage de modéliser chaque réponse possible (y compris les distracteurs) tout en autorisant une réponse au hasard pour les participants de compétence plus faibles. Une comparaison des approches dichotomique et polytomique est réalisée au moyen de données simulées selon un modèle de réponse au hasard plausible. Les avantages et inconvénients de l’approche polytomique, tant du point de vue technique que pédagogique, sont discutés. [less ▲]

We introduce a generalization of Pascal triangle based on binomial coefficients of finite words. These coefficients count the number of times a word appears as a subsequence of another finite word. Similarly to the Sierpinski gasket that can be built as the limit set, for the Hausdorff distance, of a convergent sequence of normalized compact blocks extracted from Pascal triangle modulo 2, we show the existence of a subset of [0, 1]×[0, 1] associated with this extended Pascal triangle modulo a prime p.

The Walloon Region Soil decree proposes a series of guidance documents associated to the procedures for site remediation operations. Among others, one of these documents describes methodologies and tools for risk assessment of pollutant leaching from soil to groundwater and for pollutant dispersion through groundwater. These tools require using estimates of hydrogeolocial parameters such as hydraulic conductivity, effective (transport) porosity etc. In this context, an inventory of hydrogeological studies (regional characterization studies, groundwater protection zones…) was performed to identify and collect available field-based measurements for a statistical description and analysis of such data. Complementary to that, a simple geodatabase has been developed to manage and process these data. As expected, these results show contrasted parameter distributions per geological contexts and regions. The objective of the presentation is to describe the methodology followed for the statistical treatment of hydrogeological data and to present the results and associated database. It is believed that such results can be very useful for different hydrogeological studies, in particular as a first referential for groundwater modelling applications and any other studies where statistical descriptions of hydrogeological data are relevant.

Almost a century ago, Presburger showed that the first order theory of the natural numbers with addition is decidable. Following the work of B\"uchi in 1960, this result still holds when adding a function $V_k$ to the structure, where $V_k(n)$ is the largest power of $k\ge 2$ diving $n$. In particular, this leads to a logical characterization of the $k$-automatic sequences. During the last few years, many applications of this result have been considered in combinatorics on words, mostly by J. Shallit and his coauthors. In this talk, we will present this theorem of B\"uchi where decidability relies on finite automata. Then we will review some results about automatic sequences or morphic words that can be proved automatically (i.e., the proof is carried on by an algorithm). Finally, we will sketch the limitation of this technique. With a single line formula, one can prove automatically that the Thue-Morse word has no overlap but, hopefully, not all the combinatorial properties of morphic words can be derived in this way. We will not assume any background in combinatorics on words from the audience. [less ▲]

Introduction For years, bad news delivery’s impact on patients or their relatives, as well as physicians’ stress has been a major concern. Based on studies claiming the efficacy of training courses to help physicians delivering such news, many protocols, like SPIKES, BREAKS or SHARE, have emerged worldwide. However, training to such protocol might be time-consuming and not suitable with junior doctors or trainees’ turnover. We hypothesised that a standardized 5-hours training program could improve bad news delivery practice. Participants and methods This preliminary study was conducted in the ED of a tertiary care academic hospital accounting for 90000 ED census per year, 16 attending physicians, 10 junior residents, and 5 trainees per month. Data were collected between November 2015 and April 2016. The study included 3 phases over 4 weeks. Video recorded single role-playing sessions happened the 1st (T1) and the 4th (T3) weeks. A 3-hour theory lesson happened the second week (T2), introducing the basics of therapeutic communication and delivering bad news. Each role-playing session lasted almost 1 hour (10 minutes briefing and medical case reading, 10 minutes role-plays and 40 minutes group debriefing). Bad news delivery performance was evaluated by a 14-points retrospective assessment tool (1). We collected data about the status and impact of a stressful event at 3-days using the French version of the IES-R scale (2). We applied Student t-tests for statistical analysis. Results 14 volunteers (10 trainees and 4 junior emergency physicians) were included in the study. On average, bad-news delivery process took 9’45’’ at T1 and 10’20’’ at T3. From T1 to T3, bad-news delivery performance increased significantly for both junior emergency physicians and trainees (p=0.0003 and p=0.0006, respectively). Further analysis revealed that most relevant increases involved the “situation” (p<0.001), “presentation” (p=0.009), “knowledge” (p=0.037), “emotions” (p=0.01) and “summary” (p=0.001) steps. We also found a significant decrease of the impact of bad-news delivery on trainee physicians’ stress (p=0.006). Discussion and conclusion These preliminary results indicate some potential for this new standardized course of bad news delivery. Apart from allowing physicians increase their communications skills, we believe that this simple 5-hour simulation-training program could alleviate physicians’ stress when they happen to break bad news.
