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 ▲]

Speleothems, presented in Belgium, are now regarded as valuable archive of paelenvirenmental variations on the continents, offering a number of advantages relative to other continental climate proxy recorders such as lake sediments. They are reliable continental archives of high interest due to their dating possibilities and their possibility to preserve multi-proxy records of environmental and climatic dynamics. Establishing high-resolution trace element time series in speleothems requires analytical techniques capable of representative sampling at sub-annual spatial resolution (on order of 22 µm in this study). In the Belgian Pere Noel cave (PN), high spatial resolution measurements of trace elements (e.g., Mg, Sr, Ba) were realized by using LA-ICP-MS and compared with results from lower resolution techniques (ICP-MS). The results from both techniques have been analysed in order to assess the capability of each technique to reconstruct climate changes at high resolution from PN stalagmite. Results showed that LA-ICP-MS technique allows a rapid analysis of multiple elemental concentrations, and uses minimal sample volume allowing for replicate sampling and availability of almost the entire original sample for other analyses.

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.

Natural estrogens (estrone: E1, 17-β-estradiol : E2, estriol : E3) and synthetic estrogen (17-α-ethinylestradiol: EE2) are powerful endocrine disruptors. They may have deleterious effects on aquatic wildlife and also humans even at extremely low concentrations. For this reason, these molecules have been included in a watch list from the European Commission regarding emerging aquatic pollutants. The maximum detection limits are set at 0.035 and 0.40 ng/L for EE2 and E1, E2 respectively. Reaching such low levels of concentration of estrogenic compounds is a challenge, even using state-of-the-art analytical methods. In this study, we developed a UHPLC-ESI-MS/MS method allowing the quantification of E1, E2, E3 and EE2 residues in aqueous matrices. Studies commonly used ESI in negative mode albeit the poor ionization efficiency of native estrogenic compounds in this mode. In this study, the molecules were derivatised using a sulfonyl chloride reagent (pyridine-3-sulfonyl, P-3-S). The resulting response in the positive mode was significantly enhanced. Similarly to other dansyl derivatives, the product ion spectra of the P-3-S derivatives indicate ions originating from the derivatization reagent moiety. Moreover, several other ions were included in the product ion spectra of the P-3-S derivatives. Their specificity was assessed by a qualitative approach implying the analysis of different types of water samples (groundwater, surface water). Some product ions were found to be noticeably better for quantification and confirmation of the analytes. The developed analytical method was validated according to the NF T90-210 norm which is suitable to assess the performances of a method in the water quality field. The limits of quantification were 0.04, 0.05, 0.10 and 0.02 ng/L in groundwater and 0.89, 0.79,4.42 and 0.29 ng/L in surface water for E1, E2, E3 and EE2 respectively. [less ▲]

Alkaloids are a class of naturally occurring organic nitrogen-containing bases that are found primarily in plants. They display a huge diversity with more than 3,000 different types already identified. Next to their different pharmacological and therapeutic effects, alkaloids can have a deleterious impact on organisms as they are known to be neurotoxic and cardiotoxic for mammals and insects. In the current context of worldwide bee decline, occurrence of such compounds in floral production, i.e. nectar and pollen, raises major concerns. They could be beneficial to bees by protecting them against disease and pathogens but they could also cause toxicity. Until now alkaloids, and their effect on human health, are mainly studied in vegetative parts of plants. More recently the natural occurrence of alkaloids in nectar was also studied to investigate their effect on bee health. Whereas nectar chemicals can relatively easily and quickly be analyzed by chromatography, extracting chemicals from low pollen amount remains a challenge because of pollen structure and complexity. However, characterization of pollen chemicals can lead to valuable insight in their impact on pollinators allowing the development of mitigation strategies. In this study, we used a UHPLC-(ESI)-Q-ToF/MS method allowing the identification and quantification of alkaloids in pollen matrices from four Aconitum species; A. lycoctonum, A. napellus compactum, A. napellus neomontanum and A. variegatum. Alkaloid extraction was performed using bead-beating disruption of the pollen sample and chromatographic analysis was carried out on an Acquity UPLC system interfaced with a Synapt G2 QTOF. The separation was achieved in gradient mode on an Acquity UPLC BEH C18 column and detection was performed in electrospray positive ionization mode (ES+). Alkaloid concentrations were measured as aconitine equivalents by using a pure aconitine standard as reference compound. The total amount of alkaloids in Aconitum pollen ranged from 0.75 to 1.20 mg/g with 859 different compounds detected, some of them being pollen-specific. Statistical analyses were conducted on the global dataset to assess both quantitative and qualitative interspecific differences. One-way analysis of variance was performed on the total alkaloid content while a permutational test of multivatiate analysis of variance was used to compare the alkaloid profiles among the four Aconitum species. Results are briefly discussed in an ecological context. [less ▲]

Concrete frame structures often include both slender and deep beams. Deep beams possess a large shear capacity, and thus are typically used as transfer girders to carry heavy loads over large spans. The overloading of such members due to extreme events such as earthquakes may result in the collapse of the entire structure. To evaluate the resilience of large frame structures under extreme loading, it is necessary to model the interaction between the deep girders and the rest of the structure in an accurate and computationally effective manner. To address this issue, this paper proposes a mixed-type modelling framework by formulating an innovative 1D macro deep-beam element and coupling it with 1D slender elements. The new macro element aims to combine the accuracy of 2D micro finite elements with the simplicity of 1D macro elements. The paper summarizes the formulations of this element, based on the three-parameter kinematic theory, and integrates it into an existing global nonlinear analysis procedure to create a mixed-type modeling framework. The verification study, including a frame structure with a deep transfer girder, has shown that this approach captures the response of the frame with an accuracy similar to that of 2D micro finite elements, while requiring approx. 20% of the analysis time.

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.

Contrairement aux autres manuels de grammaire latine destinés aux hellénophones, comme ceux de Charisius, Diomède et Priscien qui travaillent dans la pars Orientis pour des hellénophones, l’Ars grammatica de Dosithée est accompagnée d’une traduction grecque. La présence de cette traduction, qui ne concerne toutefois pas toute la grammaire, mais seulement environ la moitié du texte, singularise ce manuel dans la tradition des artes, même si nous ne pouvons exclure que d’autres traités grammaticaux du même type n’aient pas été accompagnés d’une traduction grecque que nous n’aurions pas conservée. Quoi qu’il en soit, le statut de cette traduction est assez difficile à établir. Essentiellement deux questions se posent à son sujet : quel est son auteur, est-ce Dosithée lui-même ou un utilisateur plus tardif (éventuellement dans le monde occidental), et à quoi sert-elle ? Il apparaît clairement que le grec doit aider à la compréhension du latin, non le remplacer. La traduction grecque n’a donc pas une vocation à l’autonomie. Elle n’a de sens qu’en relation avec le latin. La traduction semble se réduire au fur et à mesure que l’on avance dans la grammaire. Il semble que Dosithée attende de l’utilisateur de la grammaire qu’il ait de moins en moins besoin d’aide à mesure qu’il progresse dans l’apprentissage.

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.

Hydrogeophysics is an interdisciplinary field of sciences aiming at a better understanding of subsurface hydrological processes. If geophysical surveys have been successfully used to qualitatively characterize the subsurface, two important challenges remain for a better quantification of hydrological processes: (1) the inversion of geophysical data and (2) their integration in hydrological subsurface models. The classical inversion approach using regularization suffers from spatially and temporally varying resolution and yields geologically unrealistic solutions without uncertainty quantification, making their utilization for hydrogeological calibration less consistent. More advanced techniques such as coupled inversion allow for a direct use of geophysical data for conditioning groundwater and solute transport model calibration. However, the technique is difficult to apply in complex cases and remains computationally demanding to estimate uncertainty. In a recent study, we investigate a prediction-focused approach (PFA) to directly estimate subsurface physical properties from geophysical data, circumventing the need for classic inversions. In PFA, we seek a direct relationship between the data and the subsurface variables we want to predict (the forecast). This relationship is obtained through a prior set of subsurface models for which both data and forecast are computed. A direct relationship can often be derived through dimension reduction techniques. PFA offers a framework for both hydrogeophysical “inversion” and hydrogeophysical data integration. For hydrogeophysical “inversion”, the considered forecast variable is the subsurface variable, such as the salinity. An ensemble of possible solutions is generated, allowing uncertainty quantification. For hydrogeophysical data integration, the forecast variable becomes the prediction we want to make with our subsurface models, such as the concentration of contaminant in a drinking water production well. Geophysical and hydrological data are combined to derive a direct relationship between data and forecast. We illustrate the process for the design of an aquifer thermal energy storage (ATES) system. An ATES system can theoretically recover in winter the heat stored in the aquifer during summer. In practice, the energy efficiency is often lower than expected due to spatial heterogeneity of hydraulic properties combined to a non-favorable hydrogeological gradient. A proper design of ATES systems should consider the uncertainty of the prediction related to those parameters. With a global sensitivity analysis, we identify sensitive parameters for heat storage prediction and validate the use of a short term heat tracing experiment monitored with geophysics to generate informative data. First, we illustrate how PFA can be used to successfully derive the distribution of temperature in the aquifer from ERT during the heat tracing experiment. Then, we successfully integrate the geophysical data to predict medium-term heat storage in the aquifer using PFA. The result is a full quantification of the posterior distribution of the prediction conditioned to observed data in a relatively limited time budget. [less ▲]

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.

Durant le Paléolithique moyen, l’alternance entre les périodes glaciaire et interglaciaire a rendu le peuplement de la France septentrionale discontinu. Cette région bénéficie d’un bon cadre chronostratigraphique permettant l’étude des peuplements néandertaliens. Cependant certains aspects de leurs comportements restent encore mal caractérisés, particulièrement la fonction des sites reste souvent à préciser. L’étude de l’organisation spatiale intrasite apporte des éléments de réponse à ces questions. La fouille d’un site du Paléolithique moyen ne met pas directement en évidence l’organisation spatiale des lieux de vie, une modélisation est nécessaire pour la déceler. Nous avons donc débuté la construction d’un protocole d’analyse spatiale basé sur un Système d’Information Géographique et appuyé sur les sites de Caours. Ce site possède un rôle majeur de par sa superficie et l’excellente préservation des restes fauniques. Nous montrons ici l’existence d’une organisation spatiale sous forme de zones de concentration de vestiges en corrélant plusieurs méthodes – parmi lesquelles le K-mean Clustering et la Kernel Density Estimation. Nous préciserons ensuite la fonction de ces zones au sein d’un espace de vie et leur interaction entre elles au travers de la distribution spatiale des différents vestiges fauniques ou lithiques.

Continuous-flow micro- and mesofluidic reactors come with inherent properties that can be advantageously utilized for expanding the horizon of synthetic organic chemistry. Accurate control over local process parameters, even under extreme conditions, inherent safety, production homogeneity and seamless scale-up are amongst the most important assets of continuous-flow chemistry. Besides, flow chemistry enables the design of efficient multistep processes with significantly reduced footprints. In this lecture, we will discuss some of the most fascinating aspects of continuous-flow micro- and mesofluidic reactors in the specific context of preparative organic chemistry. Multiple examples illustrating the development and implementation of continuous-flow multistep strategies for the synthesis of high-value added organic targets will be presented. [less ▲]

Le triangle de Pascal classique ainsi que le triangle de Sierpiński sont des objets largement étudiés. Ils montrent des aspects auto-similaires et ont des liens avec les systèmes dynamiques, les automates cellulaires, la théorie des nombres et les suites dites automatiques. Dans ce séminaire, nous présentons un travail en collaboration avec Julien Leroy et Michel Rigo. Dans un premier temps, nous introduisons une généralisation du triangle de Pascal basée sur les coefficients binomiaux de mots finis et nous étudions le cas plus particulier des représentations en base 2. Ces coefficients comptent le nombre de fois qu’un mot fini apparaît comme sous-suite d’un autre mot fini. De la même façon que le triangle de Sierpiński peut être construit comme l’ensemble limite, pour la distance de Hausdorff, d’une suite convergente de compacts renormalisés extraits du triangle de Pascal classique modulo 2, nous décrivons et étudions les premières propriétés du sous-ensemble de [0, 1] × [0, 1] associé à ce triangle de Pascal généralisé modulo un nombre premier p. Dans un second temps, nous étudions la suite qui compte, sur chaque ligne du triangle de Pascal généralisé en base 2, le nombre de coefficients binomiaux strictement positifs. Cette suite présente une régularité étonnante qui peut être mise en évidence en utilisant une structure particulière de graphes, appelée arbre des sous-mots. [less ▲]

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 ▲]

Sever fires in buildings can lead to local failures, instability, partial or total collapse of the structure. In majority of the times, fire is a secondary event, after blast or impact, while the building has experienced some damage. Examples of widely known events include the 1968 Ronan Point collapse in the UK, the 1995 Oklahoma City bombing, the World Trade Center Collapse in New York in 2001, the 2014 collapse of a building at New York’s Harlem neighborhood due to a gas explosion, and the recent 2015 collapse of a building at New York’s East Village also due to a gas explosion. The initial shock to the building can be conservatively modeled by removing an intermediate vertical supporting element (i.e. loss of load-carrying capacity in a critical element), leading to an increased span for composite floor slabs. In a lowrise building, if there is enough reinforcement throughout the slab and enough continuity and restraint, despite large deflections that will develop, the slab is capable of carrying the loads by membrane action. Fundamentally, the floor system behaves as an inverted dome structure with radial tensile forces and a compressive hoop stresses. This holds true at ambient temperature, yet a similar resisting mechanism forms during fire. Previous research and experimental work shows that fire performance of composite floor slabs can be used to reduce the fire protection requirement of the steel elements, i.e. the designer should take advantage of reserve capacity in the composite floor slab membrane action. The utilization of membrane action in the design of composite floor slabs has been used, to some extent, for mitigating collapse from single events (blast or fire only). Given that, often the initial blast is followed by a secondary fire event, this work investigates the system-level performance of low-rise damaged buildings subject to post-blast fires. The hypothesis is that, when incorporated in the design, low-rise buildings can withstand the post-blast fires through membrane action of composite floor slabs. Application of this concept, within a performance-based framework, can be used to avoid progressive collapse, or at the minimum increase fire resistance to allow for safe evacuation. This work investigates the design requirements for beam sizes, fire protection, concrete reinforcement and cover thickness to develop membrane action for a pre-defined fire resistance rating under cascading post-blast fires.

In the last fifteen years, Belgian prisons have been characterized by an increase of managerial and legal regulations. This rise of “inscribed knowledge” (Freeman & Sturdy, 2015) however leads to a sharper need of prison governors for “practical wisdom” (Chia and Holt, 2009). Firstly, because law and policy don't apply automatically, but must always be interpreted by human actors in relation to the situation. Secondly, because the increase of legal and managerial inscriptions reinforces prison governors’ more general inclinations to “satisficing” decisions (March and Simon, 1958). Drawing on four years of qualitative research with 40 Belgian prison governors, this empirically based paper analyses how they cope with complex, uncertain and ambiguous situations where neither epistemic nor technical knowledge is available. In doing so, we assume that they – at least marginally – “enact” prison organisations and prison policy (Weick, 1988). [less ▲]

Background For the documentation of the clinical data, the International Classification of Primary Care (ICPC-2) is used, often in conjunction with the more granular International Classification of Diseases (ICD). For retrieval of scientific bibliographic information in GP/FM, Medical Subject Headings (MeSH) are used. With over 25,000 available MeSH descriptors, indexing is not easy, and yet not all aspects of the broad field of GM/FM are covered . ICPC-2 has been developed to identify reasons for encounter, symptoms, acts performed or requested and diagnosis in daily practice: It captures clinical encounters for epidemiological research. But, it was not constructed to reflect the non-clinical aspects of the profession, such as organizational, managerial, educational, and investigational aspects. Recently, a new taxonomy of organizational aspect of GM/FM has been developed to ameliorate this situation. The purpose of this development was to provide tools to exploit modern technology in terminology for information storage and retrieval systems , such as machine learning, semantic web techniques and natural language processing (NLP). The 182 concepts identified were thoroughly described in terminology records, which are freely accessible on the web (www.hetop.eu/Q). All concept and definitions were translated into 8 languages and are available online. (http://3cgp.woncaeurope.org). A book is available in 6 languages To develop the Q-codes 1700 abstracts of GP/FM congresses have been carefully analyzed. This has been the basis of the work. As a team of the EGRPN has also analyzed 600 EGPRN abstracts and developed a taxonomy of research, I have this work has been incorporated to update the QR domain. Thus ongoing Q-Codes are based on the analysis of 2300 abstracts The most important fact is that there is a Q-Codes only if the theme has been discussed by physicians during congresses. This is a bottom-up approach which contrast with the expert approach of the authors of textbook The Q-Codes have been integrated with the clinical classification ICPC-2 into a coherent whole, under the name Core Content of General Practice and Family Medicine (3CGP), for further enhancement of medical documentation and indexing of GP/FM master thesis and congress abstracts The value of a taxonomy is determined by the quality and speed of the maintenance and updating process. This will be handled by a working group of the Wonca International Classification Committee (WICC) (www.ph3c.org/Q) already authors of ICPC-2. Aim to present the preventive aspects of the Q-codes, a taxonomy specifically directed to describe the managerial aspects of GP/FM.

L’appel au peuple contre des élites (politiques, économiques,…) constitue le cœur de la rhétorique populiste. Cependant, cette invocation du peuple, des hommes de la rue, des citoyens ordinaires n’est pas un acte strictement populiste. En effet, si la démocratie peut se définir, entre autre, comme le pouvoir au peuple, n’induit-elle pas alors un nécessaires recours à sa mobilisation ? Comment distinguer l’appel au peuple du discours populiste, d’un discours démocratique ? Plus précisément, comment pouvons-nous définir le peuple ? Et quels sont les enjeux politiques et idéologiques qui sous-tendent sa mobilisation dans la rhétorique populiste ? Pour répondre à cette interrogation, nous proposons, dans un premier temps, en nous appuyant sur la littérature scientifique, de clarifier la notion de peuple et de populisme. Dans un second temps, nous étudierons le discours politique du Front national français tout en mobilisant les apports théoriques précédemment analysés. Pour ce faire, nous concentrerons notre attention sur le programme du parti, les communications orales de ses principaux représentants ainsi que les différents éditoriaux publiés sur leurs sites internet. L’analyse est discursive. En guise de conclusion, nous reviendrons sur la classification du Front national en tant que parti populiste tout en essayant de dégager les points communs et les divergences que nous pouvons observer entre la notion de peuple telle que définie par la littérature scientifique sur la démocratie, le populisme et dans les discours du FN. À terme, nous espérons ainsi mieux comprendre la notion de peuple dans l’argumentaire frontiste ainsi que ses différents éléments constituants. [less ▲]

Revenant sur les appels à la « fierté collective », au « patriotisme économique » et au « nationalisme d’ouverture » réitérés par les derniers Ministres-Présidents à la tête de la Wallonie, la communication s’attache à montrer comment ces tentatives de revitalisation d’un sentiment d’attachement identitaire, tout en relevant des manifestations du « nationalisme banal » (M. Billig), entretiennent le déficit d’imaginaire régional, réduit au développement de la « marque Wallonie » et de sa promotion auprès de ses habitants et des investisseurs. L’insistance sur la seule valeur économique et instrumentale de la communauté, visant à améliorer la compétitivité de la région sur son marché global et intérieur, fait d’autant mieux ressortir, par contraste, la dimension narrative sous-jacente à l’imagination nationaliste, particulièrement mise en évidence dans la nouvelle économie de l’enrichissement (L. Boltanski et A. Esquerre), fondée sur la patrimonialisation et l’exploitation du passé comme gisement de valeur. Du croisement des deux axes ainsi dégagés (nationalisme de faible ou forte intensité ; recours plus ou moins appuyé au storytelling), émerge une conception élargie du nationalisme, qui en fait apparaître de nouvelles modalités et permet d’ouvrir à une autre compréhension de doctrines comme le national-libéralisme ou le projet post-national. Dans la continuité des observations de M. Billig, notre cadre d'analyse structurale tend à faire des mouvements nationalistes (au sens le plus courant du terme dans l’analyse politique) un simple cas particulier parmi d’autres modes de participation plus ordinaires, infra-conscientes et naturalisées, à la communauté nationale.

Pliosaurids are iconic marine reptiles that dominated marine ecosystems during the Jurassic and the Cretaceous. These giant predators met their demise during the early Late Cretaceous but the final chapter of their long evolutionary history remains barely documented. Prompted by the discovery of a peculiar and very well preserved new taxon from Russia, we compute the evolution of pliosaurid disparity from their Early Jurassic radiation to their Late Cretaceous extinction. Despite a patchy Early Cretaceous fossil record, we show pliosaurids reached their maximal disparity during the Hauterivian-Barremian interval, suggesting a strong Early Cretaceous recovery from the apparently low phenotypic disparity of Late Jurassic pliosaurids. By using cladistic and ecomorphological data, we show that pliosaurids have repeatedly evolved slender-snouted polycotylid-like morphologies in each of their temporal radiations (Early Jurassic, Middle Jurassic and Early Cretaceous), demonstrating a more complex evolutionary history than their traditional representation as gigantic apex predators of Mesozoic marine ecosystems suggests. The extinction of pliosaurids during the Turonian (early Late Cretaceous) appears preceded by a late Early Cretaceous contraction of their disparity, the trajectory documented in ichthyosaurs, another successful marine reptile clade that disappeared during the Cenomanian-Turonian interval.

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 ▲]

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 ▲]

La dégradation considérable de la qualité de l’eau et les utilisations concurentielles de cette ressource par tous les secteurs s’accèlèrent, notamment en région méditerranéenne. Certains pays souffrant déjà de la rareté de leurs ressources en eau seront de plus en plus menacés dans un futur proche. Cette situation de pénurie serait aggravée par les dérèglements climatiques qui menacent les ressources en eau par l’augmentation de l’évaporation des reservoirs et des plans d’eau et par la fréquence des inondatons et des sécheresses. La Tunisie fait partie des pays les plus vulnérables de la région méditerranéenne. Le pays est classé selon l’indice de Falkenmark parmi les pays en pénurie d’eau, ce qui rend la disponibilité naturelle de cette ressource insuffisante pour satisfaire une demande en hausse. En effet, selon l’organisation des nations unies pour l’alimentation et l’agriculture (FAO, 2014), les disponibilités en eau douce de la Tunisie baisseraient à 450 m3/habitant/an en 2030 et à 427 m3/habitant/an en 2050. En 2015, les apports cumulés aux barrages ont enregistré une baisse de 66% par rapport à la moyenne. Cette baisse a le plus affecté la région du Nord, forte contributrice au stockage d’eau de surface (plus de 80% des ressources en eau de surface). Le barrage Joumine était parmi les barrages les plus affectés par cette baisse enregistrant une perte de stockage de 37 Mm3 en une année, soit 30% de sa capacité utile actuelle. A cette baisse de la ressource s’associe la vulnérabilité à la pollution diffuse. En effet, le bassin versant de l’oued Joumine est un bassin versant agricole dominé par les cultures céréalières très exigeantes en intrants (192 milles tonnes d’Ammonitrate, 25,9 milles tonnes de superphosphate 45 et 82 milles tonnes de DAP pour le total des surfaces céréalières emblavées du pays) (DGPA, 2016). Dans ce travail, on estime ces apports issus des terres agricoles et évalue sa réponse face aux nombreuses pressions dans un contexte de changement climatique. La méthodologie adoptée implique, en plus des observations et prospection terrain, la représentation mathématique de la relation « pression – impact », modélisée par le logiciel PEGOPERA, outil de simulation numérique de l’écosystème rivière développé par l’Unité R&D de l’Aquapôle de l’Université de Liège. Le but étant de fournir une image de la qualité de l’eau de l’oued Joumine dans des conditions hydrologiques particulières, à un pas de temps journalier et en tout point du réseau en assurant des simulations physiquement basées avec un outil dédié au calcul déterministe des écosystèmes rivières à partir des données des débits mesurés, la température de l’eau, les insolations solaires et les rejets (Deliège et al., 2009; Deliege et al 2014 ; Grard et al 2014). La mise en place du modèle a nécessité la construction d’une base de données géographique à partir des informations relatives à l’occupation des terres et le relief, le tracé digitalisé des rivières et le découpage administratif par délégation. Des algorithmes de pré-processing PEGASE ont été appliqués pour la construction et la vérification de la topologie du réseau hydrographique, la génération des profils altimétriques des rivières et de la connectivité. Une méthode d’interfaçage a été par ailleurs définie avec le modèle agro-hydrologique SWAT en vue du calcul déterministe et explicite des apports diffus des sols tout en s’assurant de la cohérence des échelles temporelle et spatiale entre les deux modèles et des processus modélisés. Le modéle a été paramétré pour simuler l’état du systéme depuis l’année hydrologique 2015/2016 et des scénarios prospectifs sont en cours d’étude pour simuler la réponse du système dans des situations particulières, notamment les projections climatiques futures.

BACKGROUND: In Belgium, music theory teachers teach theoretical aspects of rhythm, singing and other music-related skills (such as pitch accuracy or singing in harmony) outside the regular school setting. To date, their voice use and how it may be affected by background noise have hardly been studied. OBJECTIVES: 1) to determine the relationship between music theory teachers’ vocal loading and background noise and 2) to examine if the daily number of vocal fold vibration cycles (vocal loading index, VLI) is reflected in the teachers’ auto-evaluation of their voice. METHODS: A VoxLog voice dosimeter (Sonvox) was used to monitor 13 music theory teachers for one 6-day workweek from the early morning until late evening. Parameters analysed were fundamental frequency (F0, Hz), voice sound pressure level (SPL, dB), time dose (%), noise SPL (dB), and VLI. At the end of each monitoring day, subjects evaluated their voice quality, vocal fatigue, and amount of speaking and singing voice used by means of a visual analogue scale. RESULTS: Statistical analysis revealed positive correlations between noise SPL and F0, voice SPL and time dose. Correlations were also found between VLI and auto-evaluation data: a rise in VLI accompanied a decrease in self-perceived voice quality, an increase in vocal fatigue and an increase in the perceived amount of singing and speaking voice used. CONCLUSION: Three conclusions were drawn from the results. Firstly, vocal loading measured in music theory teachers is connected to the background noise level. Secondly, a great number of vibration cycles is associated with a self-reported increase in vocal fatigue and a lower general voice quality at the end of the day. Finally, correlations between the number of vibration cycles and the self-reported amount of voice use suggest that visual analogue scales are a reliable method to evaluate daily voice use. [less ▲]

The legal situation of Belgian gay men and lesbians may be perceived as one of the best in Europe. Indeed, the Belgian Parliament has legalized marriage and parenting for same-sex couples, has enacted anti-discrimination laws, and has funded several action plans to combat homophobia. More particularly, the access to parenthood is legally possible for same-sex couples through adoption, artificial insemination and in vitro fecundation. In this supportive political context, lots of same-sex-headed families exist. However, same-sex parenting is still considered as a controversial topic by some heterosexual people. Therefore, this paper aims at understanding heterosexuals’ attitudes towards the different types of same-sex parenting as well as the rationales underlying those attitudes. In Study 1, the degrees of support of 1168 heterosexual participants aged from 18 to 81 towards those types of parenting have been analysed through a self-report questionnaire. Results revealed that heterosexuals’ participants do not show the same degree of support towards the different types of same-sex parenting. In particular, adoption by lesbian and gay couples is the more accepted type of parenting, followed by artificial insemination. Then, adoption for single lesbians or gay men and surrogacy are the types of parenting that are the less supported. Then, though the content analysis of comments posted on social networks (Study 2), we highlighted the arguments in favour and against those specific types of parenting. Those results highlight that citizens’ attitudes can go from supportive to unsupportive and this could lead to some kind of discrimination towards children raised in specific forms of same-sex-headed families. This contribution highlights work’s implication for public policy and social transformation by understanding the challenges that gay and lesbian couples and their children have to face. [less ▲]

Dans cet exposé, j'analyse le cas Montjean, inscrit au cœur de la pratique fargienne. Il m’intéresse particulièrement : il est révélateur tant du projet d’Arlette Farge que de sa mise en œuvre. Une première fois appréhendé au sein d’un ouvrage – La vie fragile (Paris, Hachette, 1986) – qui annonce, en bien des lieux, la poétique de l’historienne, on le retrouve dans une étude récente qui, selon moi, condense – tout en légèreté – les outils de l’atelier fargien. J’estime, en effet, que La révolte de Mme Montjean (Paris, Albin Michel, 2016) est une sorte de manifeste qui, évidemment, ne se donne pas explicitement comme tel. Mais en la parcourant, librement, chapitre par chapitre, je montrerai que les fondamentaux de la pratique d’Arlette Farge – telle que je tente de la formaliser par le biais du paradigme visuel – y sont formulés.

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.

Making plastics more sustainable by valorizing waste CO2 as a cheap, inexhaustible and renewable feedstock is an early stage technology with strong innovation potential that imposes itself as a strategic driver for developing future low carbon footprint materials and technologies. With a global production estimated to 18 million tons for 2016, polyurethane (PU) is one of the most important polymers in our everyday life applications (automotive, building and construction, coatings, etc.). Industrially, PU is produced by step-growth polymerization between di- or polyisocyanates and di- or polyols. However, isocyanates are toxic and drastic changes in the REACH regulations limiting/banning the use of isocyanates are expected. There is a need today to develop new greener and safer alternatives to produce PU. Valorizing CO2 as C1 feedstock for producing precursors entering in the synthesis of polyurethanes by a non-isocyanate route (NIPU) is a promising strategy to solve this challenge. In this talk, we will focus on the synthesis and characterization of novel NIPUs foams for thermal insulation, and NIPUs coatings for metal protection. Our research highlights benefit of merging bio-resources (such as vegetable oils) with carbon dioxide transformation. In the first part of this talk, we will report on the fast synthesis of bio- and CO2-sourced cyclic carbonates by coupling CO2 with epoxides using a new highly efficient bicomponent homogeneous organocatalyst under solvent-free and mild experimental conditions. The mechanism of the activation of the reaction will be discussed, and scaling up of the technology will be demonstrated (15kg scale). In the second part, we will illustrate the use of these bio- and CO2-sourced cyclic carbonates for the production of microcellular NIPU foams with closed cells morphology for thermal insulating applications, but also for preparing hybrid NIPUs coatings for metal protection.
