Au cœur de l'espace de la cour, le confesseur du Prince présente un profil singulier. La relation qu'il entretient avec son pénitent est unique : tenu à l'obéissance envers le souverain ou son représentant pour les aspects temporels, ce religieux a la faculté unique d'examiner, de conseiller et de juger la spiritualité du premier personnage de l'État. Attaché à la personne du Prince, les relations de cet ecclésiastique avec les autres courtisans ne peuvent être appréhendées au moyen d'une grille de lecture hiérarchisant les rapports sociaux : échappant à l'organisation laïque – mais pas protocolaire – de la cour et ne dépendant pas directement de la Chapelle royale, le confesseur bénéficie d'une autonomie relative. En outre, son pouvoir politique, en partie officiel grâce aux dignités et charges dont ce religieux est pourvu, est avant tout perçu comme une magistrature d'influence à la portée difficilement mesurable. Enfin, les obligations matérielles liées à l'appartenance de ce prélat à un ordre religieux achèvent de distinguer cet ecclésiastique des autres serviteurs princiers. Cette communication visera à distinguer les particularités de la charge de confesseur princier au sein de la société de cour. L'étude portera particulièrement sur la cour de Bruxelles durant la première moitié du xviie siècle. [less ▲]

D’un point de vue phénoménologique, parler du corps c’est déjà ne plus être dans le corps, mais bien dans la représentation que l’on se fait de celui-ci. Il nous faut donc trouver des stratégies pour contourner cet obstacle épistémologique. Dans ce contexte, je propose de discuter de la problématique des visages en situation d’enfermement, du sort qui leur est réservé, et de leurs possibilités d’expérimenter la liberté. Je m’appuierai sur différentes situations cliniques, j’aurai recours à des œuvres d’art, et discuterai également des apports d’auteurs comme Sartre et Sami-Ali. Le temps (la permanence du changement) sera le fil conducteur de mon propos. [less ▲]

Issu d’une famille de maîtres-maçons, Jean-Charles Delsaux (1821-1893) s’oriente tout naturellement vers une carrière d’architecte, qui le mènera à celle d’architecte-restaurateur. Formé à l’Académie royale des Beaux-Arts de Liège, il a notamment pour maître l’ingénieur-architecte Julien-Etienne Rémont (1800-1883) dont l'enseignement repose sur l’étude de la Renaissance. Delsaux connaît une ascension professionnelle fulgurante: en 1845, âgé alors de 24 ans seulement, il est nommé architecte provincial. Cette fonction le prédispose à devenir, en région liégeoise, le premier architecte-restaurateur de monuments médiévaux. Il se voit par ailleurs confier la restauration de l’ancien Palais des Princes-évêques, monument emblématique de la ville de Liège. Tant les écrits de Delsaux que ses chantiers de construction et de restauration témoignent d’une parenté certaine avec les principes et réalisations d’Eugène-Emmanuel Viollet-le-Duc, ce qui lui vaut le surnom de « Viollet-le-Duc liégeois » (Di Campli, 2012). La présente communication se donne pour objectif de questionner la parenté entre les deux architectes: n’étant son cadet que de sept ans, Delsaux n’a pu recevoir l’enseignement de Viollet-le-Duc, ni directement, ni indirectement, durant ses études. Après avoir identifié les points de convergence des théories et pratiques des deux architectes à travers le cas particulier de la restauration du palais des Princes-évêques, menée de 1847 à 1865, nous chercherons à identifier les canaux de réception de la pensée Viollet-le-Ducienne en province de Liège et plus spécifiquement auprès de son contemporain Jean-Charles Delsaux qui fera, à son tour, école dans la région.

Qu’est-ce que vivre l’enfermement carcéral ? Il est sans doute plus sensé, pour commencer de répondre à cette question, d’aborder celui-ci à travers le prisme d’un phénomène privilégié. C’est le temps qui nous occupera. Cette grande coordonnée de l’existence présente un intérêt psychologique considérable bien qu’il soit plus souvent implicite que directement questionné. Nous verrons qu’en prison il existe au moins deux temporalités (celle de l’enfermement et, en parallèle, celle de l’extérieur) et que ces phénomènes sont vécus de façons inédites. Nous en arriverons à poser la question cruciale qui consiste à savoir s’il convient de s’adapter au temps carcéral ou si, au contraire, l’enjeu d’une future réinsertion est précisément de parvenir à ne pas s’adapter. Enfin, nous verrons, grâce à M. Foucault et J-P. Sartre, qu’il s’agit peut-être là du programme de ce que l’on appelle la liberté… Qu'elle s’exprime d’un côté ou de l’autre des barreaux. [less ▲]

As early as the seventies, and the introduction of pets into psychiatric hospitals (Corson, O'Leary Corson & Gwynne, 1975), it was noted that the animal presence transforms human environments, that it humanizes hospitals , alters the emotional atmosphere, and alters the way of being in the world of patients. In her analysis of the clinical work with her dog Moogli, Nadine Fossier-Varney (2016) speaks of "psychic resuscitation" to describe what happens to a bedridden resident following her introduction of Moogli. Other works emphasize increasing self-confidence, sensory-motor development (Wuang & al, 2010) or the gradual transformation of the relationship to the other as it develops as patients encounter animals in a care setting. In our opinion, these "therapeutic effects" must be understood in relation to the mode of communication that is established with animals, that is to say the mode of feeling. Drawing on the work of Stern (2037) and Roustang (2014), as well as Neisser's (1988) notion of interpersonal self, we hypothesized that bodily communication with animals alters the experience of interpersonal self by mobilizing essentially bodily modalities of being-with others. To further our understanding of the "therapeutic effects" of animals, we have begun an empirical study of the experience of encounter with an animal. Conducted via interviews with microphenomenology, the study aims to explore the experience of encounter in its bodily dimension (how is my experience of my body affected by the presence of animals?) And intersubjective . The presentation will present the first results of this study. [less ▲]

Nous aurons recours, lors de cette communication, à la dialectique obéissance/désobéissance pour appréhender certains aspects du rapport au corps des personnes présentant un diagnostic de « trouble de personnalité borderline ». Si, à certains égards, la personne borderline semble utiliser son corps comme un outil de contestation, révélant son rapport limite à la normativité – évoqué notamment par Stanghellini (2013) et Englebert (2018), à d’autres égards, elle semble tenter désespérément de faire obéir ce corps (dé)possédé. Nous tenterons de compléter les propositions issues de la psychopathologie phénoménologique et proposerons de mobiliser la notion de « (dés)obéissance du corps » dans un double rapport : celui du sujet à la société, et celui du sujet à lui-même. Notre exposé permettra d’aborder cette prise fondamentale sur le monde et sur soi dont la personne borderline se sent, apparemment, souvent dépourvue, et les efforts déployés pour tenter de la retrouver. Enfin, nous opérerons une transition vers le thème de la culpabilité, qui fera l’objet de notre conclusion. En effet, cet éprouvé, bien que souvent considéré comme absent du paysage psychique des personnes borderline (Fuchs, 2007 ; Kimura, 1992 ; Stanghellini & Rosfort, 2013), est pourtant fréquemment verbalisé par ces dernières. C’est précisément, nous semble-t-il, après la perte de contrôle (ou désobéissance) du corps, élevée à son paroxysme et contribuant à l’apparition de diverses manifestations symptomatiques spectaculaires (notamment agressives), que ces récits de culpabilité sont produits. Nous mettrons cette « culpabilité » borderline en perspective avec le modèle de la culpabilité névrotique sur fond d’obéissance et de désobéissance du corps. [less ▲]

Partant du constat ambivalent d’une dilution de la pratique revuiste telle qu’elle fut instituée dans le courant du XXe siècle – ce qu’Olivier Corpet appelle l’« âge d’or des revues » (Corpet 1988) – et d’un regain d’intérêt pour des objets appartenant désormais au patrimoine intellectuel (comme en témoignent le dictionnaire de Curatolo 2014, le numéro de Mémoire du livre codirigé par Lacroix et Martel 2012 ainsi que la création de la Revue des revues en 1987), notre communication vise à interroger l’actualité éditoriale des revues intellectuelles contemporaines dans leur rapport à la littérature au sein de l’espace francophone. Le corpus étudié est restreint au format papier, en tant qu’il exprime le besoin de perpétuer la tradition de la revue imprimée, tout en problématisant la nouvelle évidence du support numérique. La période considérée sera, pour cette raison, comprise entre les années 2000 et 2020, qui correspondent à la progressive massification de l’accès à Internet. Au sein de cette période, le corpus se définit dans un premier temps par la négative : il ne s’agit pas de traiter de revues savantes liées au monde académique, ni de magazines ou mooks distribués massivement en kiosques ou en librairie, ni encore de revues d’art spécialisées (poésie, arts graphiques, etc.). La définition positive du corpus correspond au périmètre des « revues intellectuelles », qui rassemble les critères suivants : 1° une articulation de questions philosophiques à des œuvres de création (littéraire et graphique) ; 2° un ancrage explicite dans les enjeux de la réalité politique et sociale contemporaine ; 3° une réflexivité critique sur les conditions matérielles de possibilité de l’activité intellectuelle collective et sur son historicité. Les deux dernières décennies ont vu la création, dans la seule sphère francophone, d’au moins une vingtaine de titres correspondant à cette définition : Multitudes (2000), Anartiste (2001), Inculte (2004), La Mer gelée (2004), Dé(s)générations (2005), Tina (2008), Les Nouveaux cahiers pour la folie (2011), Attaques (2012), Nawak (2013), Papier machine (2014), La Revue du Crieur (2015), Demain les flammes (2016), Dérivations (2017), Zilsel (2017), Mâtin (2018), TXT 32 (2018) et Prismes (2018). L’objectif de notre communication sera de réaliser une étude sociodiscursive et une analyse des mécanismes collectifs de l’une de ces revues – en l’occurrence Multitudes – afin de dégager les singularités rhétoriques et argumentatives constitutives d’un groupe plus ou moins cohérent. Cette étude sociodiscursive se centrera tout particulièrement sur le fonctionnement rhétorique de topoï interdiscursifs contemporains, tels que « la dilution du littéraire », « la marchandisation de l’art », « la sortie du capitalisme », « la transition écologique », le rapport entre « la question postcoloniale » et « la question migratoire » ou encore « la révolte des gilets jaunes ». Ces formules – typiques de revues telles que Multitudes, Inculte, Tina, Dé(s)générations, Anartiste ou la Revue du Crieur – véhiculent des idéologèmes forts et suscitent des effets d’adhésion ou de rejet très structurants dans l’imaginaire social contemporain. En interrogeant explicitement le rapport de la pensée au réel et en mobilisant une attitude critique envers celui-ci, elles offrent des prises idéales à un retour d’une pensée critique collective. L’analyse sociodiscursive du corpus revuiste contemporain met en évidence la reprise d’un geste théorique et critique, qui accentue le rôle de la création culturelle comme espace d’une critique des formes sociales instituées. Afin de définir les logiques groupales qui sont à l’œuvre au sein de ces revues, il sera nécessaire de réaliser conjointement une série d’enquêtes relatives au fonctionnement éditorial et aux délimitations des réseaux qui s’y constituent. Ces enquêtes permettront de réaliser un panorama des profils sociologiques constituant la production discursive de la revue Multitudes tout en délimitant ses stratégies et ses mécanismes collectifs propres. Dans le cadre d’une analyse sociodiscursive de la production revuiste, la cohabitation d’intellectuels et d’auteurs issus d’horizons divers nous obligera à interroger l’hétérogénéité rhétorique ainsi que les récurrences définitoires d’une appartenance à un collectif réuni autour d’une même revue. Il n’est bien entendu nullement question de réduire les productions individuelles et collectives à quelques unités topiques, mais au contraire de dégager l’hétérogénéité et le dialogisme constitutifs des mécanismes collectifs à l’œuvre au sein des revues et de leur traduction en discours. L’objectif est de comprendre la singularité du discours intellectuel contemporain véhiculé dans plusieurs revues intellectuelles, qui constituent une formation discursive détenant ses structures rhétoriques, ses idéologèmes, ses stratégies éditoriales et ses logiques collectives.

Navigation locks play a significant role in inland waterway infrastructures. They allow vessels to transfer from one water level to another. Because of its low cost, high transport capacity, fuel efficiency and environmental friendliness, it is expected that inland navigation transportation will grow and that locks will become larger and of more importance in the future in countries like Vietnam. Miter gates are widely used in navigation locks thanks to its economical and aesthetic aspects. Due to variations of water levels during operation, miter gates are subjected to fatigue damage caused by cyclic loading. The nature of fatigue damage is complicated because fatigue cracks can develop from various unexpected initial defects coming from the manufacturing process. Inspection and repair of developed cracks are costly because the gate needs to be put out of service. The risk-based approach for inspection and maintenance planning is based on pre-posterior decision analysis concerning the two basic decision rules about inspection and repair. This paper discusses the methods to update the failure probability of welded joints considering crack inspection data by using Dynamic Bayesian Network. This method is useful for effective computation deterioration modeling, and failure probabilities can be updated rapidly. Risk-based inspection planning combines the updated probabilities with specific costs of failure, inspection, repair and annual discounting rate in order to estimate the operation and maintenance costs, which is a substantial part of the total expected costs during the service life. The methodology is then applied to a specific case where the operation, maintenance and failure costs of a miter gate are estimated for two sets of heuristic decision rules with respect to the time of inspection: “inspections performed at regular time intervals” and “inspection performed when a certain annual probability failure threshold is reached”. It is assumed that any crack size which is equal or larger than the detectable size (detected during inspection) is repaired. The result shows that the heuristic method based on an “annual probability failure threshold” leads to a lower operation, maintenance and failure cost for the specific case study. [less ▲]

Passive acoustic monitoring (PAM) uses hydrophones to record all components of underwater soundscapes, including fish calls. Several studies have used PAM to investigate different aspects of vocal fish species, such as presence, distribution, relative abundance, diel, lunar and seasonal cycle of activity as well as for delimitating spawning areas and for studying wild fish spawning behaviour. A recent study conducted in Mediterranean rocky reefs has proved that the analysis of vocal fish communities provides high discrimination potential of species assemblages. Aside from this study, most investigations to date have considered fish species in isolation, and there is a general paucity of data addressing acoustic communication of fishes living in natural communities. We present a preliminary characterisation of vocal fish communities over a geographical and environmental gradient in Mediterranean Posidonia oceanica meadows and adjacent areas. We compared abundance and diversity of fish sounds recorded during the peak of fish vocal season in Posidonia oceanica meadows (-20 m) along a longitudinal axis (Mallorca, Corsica and Crete). In addition, for one site (Corsica), we examined the P. oceanica results in the light of the abundance and diversity of fish sounds recorded at the inferior margin of the meadow (-40 m, sandy areas). These results are discussed in a framework that highlights the investment of different vocal fish species in partitioning their active acoustic space (in terms of both frequency and time) over small- and large-scale gradients. Our study supports the potential of PAM to provide high resolution information on fish population dynamics. [less ▲]

Key-words. driving under the influence; alcohol; theory of planned behaviour; international survey; road safety culture Background. Theory of Planned Behaviour (TPB, Ajzen, 1991) is a psychological model which is widely used in traffic research to predict e.g. drunk-driving (Moan & Rise, 2011; Rivis et al., 2011, Chan et al., 2010). Some studies question its validity in cross-cultural application especially in developing countries (Nordfjærn et al., 2011). Objectives. The objective of the present study is to validate the TPB model in different cultural settings. The study is based on the results of a spin-off of ESRA (E-Survey of Road users’ Attitudes; Meesmann et al., 2018) in 2017. It investigates cross-cultural differences in self-declared drunk-driving and related behaviour determinants (TPB), such as social norms, attitudes, self-efficacy and habits in Austria, Brazil, Canada, India, Nigeria and the United Kingdom. Methods. In each county a representative sample of the national adult population (N=500) was requested to complete an online survey. Linear regression models were used to investigate the association between the behaviour determinants and self-declared drunk-driving. The models were fitted on the whole sample and the national samples separately. Results. The results show that unsafe road safety attitudes, personal and perceived acceptability of drunk-driving, a low self-efficacy to control drunk-driving, unsafe intention and habits were significantly associated with self-declared drunk-driving. The linear regression models of drunk-driving explained a satisfactory amount of variance in all countries but was lower in Nigeria (R2 Nigeria .48 all other countries >.61). Conclusions. The results of this study support the validity of the TPB model in these cross-cultural settings. The intention is to elaborate this investigation to the 32 countries of the ESRA2 survey, which will be conducted in November 2018. [less ▲]

Background. Trends in road safety performance and the success of policy measures can be monitored using road safety performance indicators based on accident statistics, road side surveys, or questionnaire surveys. However, results are seldom comparable across countries because of differences in aims, scope, or methodology. Objectives. ESRA (E-Survey of Road users’ Attitudes) is a global cross-national initiative in 46 countries, coordinated by Vias institute. Aim of this initiative is to provide scientific support to road safety policy by generating comparable national data on the current road safety situation. The use of a uniform sampling method and identical questionnaire allows comparisons across countries. Methods. ESRA is an online panel survey, using a representative sample (N=1,000) of the national adult populations in each participating country. A common questionnaire was developed and translated into national language versions. The themes covered are e.g. self-declared behaviour, attitudes and opinions on unsafe traffic behaviour, enforcement experiences and support for policy measures. The survey addresses different road safety topics (e.g. driving under the influence of alcohol, drugs and medicines, speeding, distraction) and targets all types of road users. Results. The first edition of the survey (ESRA1) was conducted in three waves (2015,2016,2017) in 38 countries (N=38,738) and in December 2018 the second edition (ESRA2_wave1) will be launched in 32 countries (expected N=32,000). This presentation is intended as an introduction for the special session on ESRA. Main outlines of the project, methodology and some key results will be described. Conclusions. The fast growth of the ESRA initiative shows the feasibility and added value of a joint data collection by a network of road safety organisations. The intention is to repeat the measurements on a triennial basis and to develop time series. [less ▲]

Background. Driving under the influence (DUI) of alcohol/drugs constitutes a main cause of road casualties. Public attitudes, legislation and enforcement measures influence the number of road accidents attributed to DUI. The ESRA survey (E-Survey of Road users’ Attitudes) provides recent data on DUI across 32 countries. Objectives. The objective of this presentation is to give an overview of the ESRA thematic report ‘Driving under the influence of alcohol and drugs’, which will be released shortly before ICADTS conference. The report is based on the second edition of the survey (ESRA2), which is currently being conducted; the data and first analyses will be available early 2019. Methods. In the descriptive analyses, self-declared impaired driving, related attitudes and opinions as well as enforcement experiences, and support for policy measures - all variables collected in the ESRA survey - are compared at the level of countries, gender and age groups. Logistic regression models explore underlying factors predicting self-declared DUI. Results. At the time of submitting this abstract, data collection for ESRA2 is ongoing. Results from the first ESRA edition (ESRA1; N=38,738) showed, that drink-driving was reported by 30% of the drivers, drug-driving by 14% and driving after taking medication that carries a warning concerning the driving ability, by 25%. The national results differ substantially, ranging from 11-43% for alcohol, 3-24% for drugs, and 7-34% for medication. Different factors have been found to be associated with impaired driving, among others ‘gender’, ‘personal acceptability’ and ‘perceived likelihood of being checked for alcohol, respectively for drugs’. Conclusion. There are notable disparities in the behaviours and attitudes towards impaired driving between the countries as well as between socio-demographic groups. The ESRA projects aims at monitoring these differences. [less ▲]

Background. Drug-impaired driving is a prominent road safety concern and research surrounding this issue is being conducted at an unprecedented pace. However much less is known about driving under the influence of prescription medication, and how to manage this road safety issue, especially in light of an aging population. Further research to support the development of tailored enforcement strategies and educational campaigns that address the risks associated with prescription medication use and driving is needed. Objectives. The objective of this study was to compare the rates of drivers in Canada, Europe and the United States who self-declare driving after taking medication with a warning that it may influence driving ability to determine what quantitative differences exist between these three regions. The effects of demographics and personal beliefs on this self-reported behaviour were also examined. Methods.

Fluorophosphate compounds attract much attention as cathode materials for Na-ion batteries. Indeed, thanks to the inductive effect of the fluoride and phosphate groups, such compounds exhibit a relatively high working potential and good theoretical capacity [1]. In this work, we focus on the iron (Na2FePO4F (NFPF)) and vanadium (Na3V2(PO4)3F3 (NVPF)) based fluorophosphate materials which are characterized by a high theoretical capacity of 124 mAh/g and 128 mAh/g, respectively. In addition, the iron-based phase is also more environmental friendly due to the low toxicity of the iron. The preparation of such complex phases using conventional solid-state route requires at least two steps with long heat treatment durations. Here, we report a facile aqueous synthesis using the spray-drying method that can be used for both NFPF and NVPF materials and that can be tuned in order to optimize the composition and the morphology of the desired materials. The major limitation of phosphate-based electrodes is their low intrinsic electronic conductivity. The synthesis of composites with carbon is an effective strategy for the enhancement of the electronic conductivity of these compounds. Spray-drying is a suitable method to incorporate carbon in composite compounds due to the high homogeneity of the obtained particle [2]. It is also a cost effective and up-scalable technique which can produce large quantities of the desired material. Here, we report the influence of the carbon addition on the structural, morphological and electrochemical properties of NFPF and NVPF compounds. The prepared composite materials were investigated by combining several characterisation techniques such as XRD, SEM and TEM. The electrochemical properties were evaluated by galvanostatic cycling and electrochemical impedance spectroscopy in Na-ion batteries. [less ▲]

Reversible deactivation radical polymerization (RDRP) has undergone impressive developments over the last decades and offers today a high level of control of polymer structures. Transition metals have deeply marked the field of RDRP leading to plethora of macromolecules with predictable molar mass, precise topology, specific composition and functionalities. Besides the popular atom transfer radical polymerization, another metal-assisted radical polymerization technique emerged, namely the organometallic-mediated radical polymerization (OMRP). The latter relies on the temporary deactivation of the growing radical chains by a transition metal complex. The OMRP notably stands out for its ability to control the polymerization of challenging ‘Less Activated Monomers’ (LAMs) deprived of radical stabilizing group on their double bond. This presentation aims at describing recent advances in the precision design of polymers by OMRP based on cobalt complexes. Special emphasis will be laid on major industrial polymers including poly(vinyl alcohol), poly(vinyl amine), poly(vinylidene fluoride) but also ethylene-containing polymers. Mechanistic aspects of OMRP will be discussed as well as the synthesis of unique statistical and block copolymers. [less ▲]

Lors de chaque année académique, une série de données, concernant le public d'étudiants en première année de médecine, dentisterie et sciences biomédicales à l'Université de Liège (Belgique), est récoltée dans le cadre du cours de physique inscrit à leur cursus. Ces données sont de plusieurs ordres : sociologique, scolaire et lié à la participation aux activités proposées à l'université. Elles doivent servir à établir des corrélations afin de dégager des tendances dont l‘occurrence permettra de fournir à l'étudiant un soutien adapté à sa situation personnelle. Ce cours de physique, donné exclusivement lors du premier quadrimestre (de septembre à décembre), est composé de séances magistrales, de répétitions (séances d'exercices) et de travaux pratiques. En complément à ce dispositif en présentiel existe une plate-forme en ligne utilisée comme instrument de soutien à l'apprentissage et de remédiation (Marique & Hoebeke, 2014). L'ensemble des outils disponibles en ligne comporte notamment un simulateur ludifié/gamifié permettant à l'étudiant de s'entraîner et de s'autoévaluer à l'aide de médailles à remporter (Marique, Van de Poël & Hoebeke, 2017 ; Marique, Van de Poël, Verpoorten & Hoebeke, 2018). Le cours de physique dans les études du secteur des sciences de la vie poursuit un double objectif : fournir les bases physiques nécessaires à la bonne compréhension de leur cursus futur et développer une démarche transversale d'apprentissage via notamment l'acquisition de compétences en résolution de problèmes et de planification de l'étude. Dans un souci de suivi de l'évolution de chaque étudiant dans ses apprentissages, un système d'évaluations formatives à intervalle régulier (mensuel) est mis œuvre dès l'année académique 2018-2019 sur la base des expériences partielles antérieures. Celui-ci repose sur 5 évènements organisés aux alentours du 15 de chaque mois de septembre à janvier. Chacun de ces tests est exclusivement composé de questions à choix multiples. Le premier test est soumis aux étudiants lors du premier cours de physique. Il porte sur les prérequis aux études de médecine et dentisterie, à savoir la matière de physique au programme de l'option scientifique de l'enseignement secondaire. Le deuxième test est organisé à l'issue des séances de cours portant sur le premier thème (l'optique pour les étudiants en médecine et dentisterie). Les troisième et quatrième tests évaluent de manière formative les étudiants sur, respectivement, la première et la seconde moitié du cours de physique de premier bachelier. En janvier est organisé l'examen certificatif. Les résultats de l'étudiant aux évaluations successives seront analysés et compilés de telle façon que celui-ci puisse mesurer son évolution dans l'acquisition de compétences méthodiques et disciplinaires. L'analyse des résultats consistera en une classification des performances de l'étudiant sur la base de la pyramide des taxonomies de Bloom (Bloom, 1956), à partir d'une évaluation des questions de chacun des tests réalisée par les membres de l'équipe pédagogique et plusieurs enseignants du secondaire. La première communication diagnostique fournie à l'étudiant est transmise à l'issue du deuxième test, après qu'une adaptation à l'enseignement universitaire et une confrontation à la matière nouvelle a pu avoir lieu. De cette façon, l'apprenant peut prendre conscience de l'éventuelle adéquation de ses méthodes d'étude avec les exigences de l'enseignement en première année de bachelier en comparant ses performances sur les matières prérequises (test 1) et nouvelles (test 2 et 3).

In this paper, we present a learning-by-doing experiment in the last Master Degree that overall aims at having students discovering and exploring design issues and physical modeling but also at exploring and practicing tectonic matter. We focus on new curriculum skills as using parametric design tools as a specific way of thinking that can extend design possibilities in digital design experimentation: the ‘design-to-fabrication continuum’. By means of a « design framework » we discuss what accurate knowledges are needed to perform a usable and relevant modelling associated to an appropriate production method, resulting in new materiality considerations. A specific part of our teaching is to present to students a novel and useful method for architectural design. We demonstrate how it can incorporate the complexity into the design space, and be an accurate help for creative thinking, especially to manage self-adaptive architectural objects. This paper exposes a « design framing” method illustrated by a multipurpose tool, discuss its limits and benefits on design and fabrication issues. We can also observe and define specific and decisive methodological design emergences. [less ▲]

Le discours scientifique apparaît bien, à l'instar des discours théoriques auxquels on le rattache ordinairement, comme un discours d'autrui (Reuter 2001; cité par Jeanneret 2004), en ce qu'il se construit à travers les voix d'autres locuteurs. C'est particulièrement vrai pour celui des sciences humaines et sociales (SHS), qui se fait également l'écho des paroles des sujets sociaux et prétend tenir un discours en leur nom (Jeanneret 2004). L'inscription du discours scientifique dans l'environnement numérique accentue encore davantage sa polyphonie constitutive : en effet, le contexte de la science ouverte, favorisant une large diffusion géographique et sociale du savoir, est vécue comme l'occasion de stimuler la grande conversation scientifique (Guédon 2014). Une pratique de communication en ligne comme le blogging de recherche reprend ainsi à son compte, pour une part, certaines marques d'oralité et la forme dialogale des séminaires et conférences académiques (Gregg 2006; Dacos et Mounier 2010) – c'est, du moins, l'imaginaire qui motive les interactions de ce dispositif médiatique, bien que celles-ci restent fortement contraintes par le choix de l'architexte ; soit, un outil d'écriture en amont du texte (Souchier et Jeanneret 1999) qui ouvre ici la possibilité pour le lecteur de commenter les publications et d'interagir de ce fait avec le locuteur. La présente contribution se propose d'étudier la conversationnalité des discours de blogs scientifiques en SHS, en prenant pour terrain d'investigation la plateforme Hypothèses[1] et en recourant aux outils de l'analyse du discours. On interrogera d'une part le dialogisme de ces textes qui, en raison de leur brouillage éditorial (Dacos et Mounier 2010), semble élargir l'empan des discours sociaux mobilisés (en ce qu'ils convoquent, outre les sources de la recherche, des discours médiatiques, issus de la culture populaire, etc.) ; et, d'autre part, la manière dont s'y inscrivent des interactions dialogales avec d'autres acteurs, que ce soit par la conduite d'interviews au sein des carnets ou par le jeu des commentaires réagissant aux billets. On s'intéressera plus spécifiquement aux décrochages énonciatifs manifestant la présence d'autrui en discours : citations, adresses, etc. – en ce compris sur le plan technodiscursifs (Paveau 2017) : on pourrait à cet égard investiguer le rôle des marqueurs hypertextuels dans le dialogisme du billet. Nous nous attacherons enfin identifier les forme(s) d'interaction(s) scientifiques visées à travers la densification de la polyphonie dans le discours scientifique en SHS sur carnet de recherche en ligne.

The long bone histology of sauropod dinosaurs appears uniform and conservative along the Sauropoda evolutionary tree. Fibrolamellar Complex (FLC), a scaffold of poorly and highly organized bone tissues, is the main 3D architecture building up the cortex of these bones. However, we report some Radial Fibrolamellar bone (RFB) in the outer cortex of the humeri of a young adult Isanosaurus (Nam Phong Formation, Upper Triassic of Thailand) and an adult Spinophorosaurus (‘Argiles de l’Irhazer’, Lower/Middle Jurassic of Niger). RFB is regarded as a fast-growing bone tissue and has been documented only in a few dinosaurian taxa including one titanosaur, but never among basal sauropods. Its outermost position within the cortex raises questions because such a rapidly apposited bone tissue would rather be expected in the inner cortex (corresponding to an early juvenile ontogenetic stage). Bone pathologies have been reviewed in order to determine whether these RFB occurrences are linked to a pathological condition. The RFB observed here is typical of periosteal reactions. Its ‘hair-on-end’ or sunburst appearance is probably related to sarcomas or metastasis around the coring sites than fracture/callus or bone infection, both of these last pathologies being completely absent from the sections and the sampled bone. Comparisons with human medicine studies and other periosteal reactions in dinosaurs are consistent with this interpretation. Intriguingly, the RFB of Spinophorosaurus is buried in the outer cortex, followed by a recovery of a ‘normal’ FLC. Spinophorosaurus thus survived its pathology and represents the first survival case of periosteal reaction-related event within Sauropoda. [less ▲]

Cape Cameroon is a small, insular territory bordering the northern shore of the Wouri estuary in Cameroon. It is located in the 6th district of the city of Douala (1 907 479 inhabitants (BUCREP, 2010)), with Manoka as its capital. It is occupied by 2654 inhabitants. This territory is occupied mainly by a Nigerian ethnic group, and the Cameroonian sovereignty has been fighting in this Cameroonian territory since the 1998-2008 conflict with Nigeria on the Bakassi peninsula.Coastal erosion is very intense and affects populations and ecosystems. Sustainable development is a particular challenge in this insular territory because the population is confronted with important coastal erosion phenomena and that cannot migrate inland because of the Mabé swamp Natural Reserve. Since the beginning of the 2000s, coastal erosion has removed houses, infrastructures and a large part of the Mabé Reserve. This contribution aims to mobilize remote sensing and GIS tools and data to (1) map the different sequences of the coastline retreat in Cape Cameroon and highlight the main factors, and (2) map the mangrove degradation due to the inland motion of the anthropic pressure, and (3) make projection for future of this territory. For modeling the coastal kinematics, the mapping is based on the Digital Shoreline Analysis System (DSAS) model, developed by Thieler et al. (2009). We used supervised classifications of Landsat images from the 1975, 1986, 2000 and 2018 with 30-meter resolution according to the maximum likelihood algorithm. We could thus assess the land use change and extract shorelines. Furthermore we use field observations, the testimonies of the people who lived for a long time along the shore to access if (1) erosion occurs continuously or during extreme events and if (2) mangrove degradation is linked to coastal erosion. Between 1986 and 2014, earth losses are estimated at more than 103 ha. Mangroves recorded a considerable degradation that the rate is estimate of 13.68%. The improved quantification of coastal erosion (in terms of soil area loss), the human occupation and land degradation through time and its possible future evolution allow to address the specific challenge of closed restricted territories occupied by growing poor and marginalized population, and the long-term sustainability of a natural reserve in such environment.

Lower Cretaceous Hauterivian sediments are found in Central Italy as part of the Maiolica Fm. These sediments present strongly contrasting lithologies. From the original radiolarian calcareous ooze that constituted the bulk of the initial deposits, biogenic silica exclusively migrated in cherts, while calcium carbonate reprecipitated into the limestones. Moreover, thin black shale levels and stylolites are enriched in insoluble elements and minerals, which contrast with the nearly pure limestone and chert (> 90 % CaCO3 and SiO2 respectively, mainly negative magnetic susceptibility for both). In this context, as part of the CRASH (Checking the Reproducibility of Astrochronology in the Hauterivian) project, we are testing whether a Milankovitch imprint is preserved through these lithologies, despite the diagenetic processes implied by their contrasting nature. High-resolution sampling was performed for cyclo- and magnetostratigraphic purposes in order to avoid the accumulation of positioning uncertainty coming from compiling heterogeneous data sets. To deal with the data in a comprehensive way we developed the StratigrapheR package, available in the free software environment R (https://CRAN.R-project.org/package=StratigrapheR). It is designed to generate lithologs and to process stratigraphical information for cyclostratigraphy. For the investigated sections it allowed to create high-resolution logs that can be queried in the R environment. As the high-resolution lithologs show all the features observed in the field they can be used to reduce the positioning uncertainties for future field missions as much as possible. Additionally they can be used to compare overlapping parts of different sections. Our preliminary work allows to correlate bundles of thin black shale sequences between two sections spanning overlapping deposition intervals, using magnetostratigraphy as a stratigraphic reference. This is further confirmed by organic matter (OM) analyses, showing similar OM preservation trends between the sections. On the other hand chert layers patterns are more difficult to match between sections. Similarities can be found using the black shale levels as reference, but discrepancies are equally frequent. The ubiquity and regularity of chert layering make it generally difficult to identify any specific pattern. Furthermore we document the "Weissert" and Faraoni events in our sections. Both present a decrease of the natural remanent magnetisation intensity, which would imply an effect of these events on magnetite. Magnetite is indeed the main contributor for the primary component of magnetisation in the Maiolica Fm. (Channell et al., 1995). The Faraoni level also marks a decrease in the concentration of lithogenic elements and in magnetic susceptibility. References Channell J. E. T., Cecca F. & Erba E. 1995.

This study develops a reflective online transparency scale, following the recommended methodological steps and precautions of a scale development process. This new scale brings clarity among existing measurement tools of web NPOs' transparency and disclosure. Preliminary to the scale construction, concepts such as transparency, disclosure and accountability are identified and differentiated in order to clearly establish what the scale assesses. A review of literature of existing measurement tools also highlights the necessity to propose a new valid and reliable transparency scale. The latter results from an exploratory factor analysis applied on a database collected from the websites of 216 philanthropic organizations collaborating with Donorinfo, a foundation working for the transparency of the Belgian philanthropic sector. The database gathers binary variables measuring the presence or absence on websites of elements of information, called items. This exploratory step refines the preliminary list of items deduced from field experts' opinion as well as a review of literature of existing measurement tools. This step also induces the dimensions of the transparency scale and the weights of each items. Normative judgements from field experts, collected through an online survey, support this exploratory step. Next, the scale is purified thanks to a confirmatory factor analysis applied on a database related to the websites of a random sample of Belgian NPOs, comparable to the Donorinfo sample. A final nomological validation step brings legitimacy to the proposed scale. As a result, the paper provides a reliable and valid online transparency scale, a measurement tool to approach online transparency in private donors' eyes. Most important references: DeVellis, R. F.

Societal, technological and economical changes in the last decades have led to the development of new work arrangements located in a « grey zone » between standard employment and classical self-employment (Cappelli & Keller, 2013a; ILO, 2016; Katz & Krueger, 2016). Official labour market statistics must be adapted to provide researchers and policymakers with relevant data on this population (Gazier et al., 2016; National Academy of Sciences, Engineering and Medicine, 2017; ILO, 2018). Cappelli & Keller (2013b) point out that new work arrangements are characterized by changes in the management of the work relationships (with a growing intervention of labour market intermediaries) and in the way the work is supervised (from work processes to outcomes). The concept of autonomy thus becomes a central feature of new work arrangements leading to specific configurations of risks and opportunities for individual workers concerned. This pleads for more detailed information on this topic. Autonomy can be divided in three main dimensions: work status, work content and working conditions (Pichault & McKeown, 2019). International surveys such as the European Working Conditions Survey (EWCS) provide valuable data covering these various dimensions of autonomy. Our paper is focused on a specific category of workers experiencing the ambiguities of autonomy at work: Independent Professionals (Ipros). Ipros provide various forms of intellectual work in the service sector through self-employment and are often regarded as a highly autonomous workforce (Leighton & Brown, 2014; McKeown, 2015) while they can also be subject to precarious situations regarding their economic dependency or freedom of choice (de Peuter, 2011; Standing, 2011; Bergvall-Kåreborn & Howcroft, 2013). The objectives of this paper are, first, to build a set of indicators likely to measure the various dimensions of autonomy by checking their statistical independence, and, second, to provide an empirical typology of new work arrangements by using cluster analysis methods. Through the application of this analytical framework on the EWCS 2015 data, we observe various situations in terms of risk and opportunities related to autonomy, shedding light on unexpected precarious situations where Ipros face the risks of autonomy without getting the associated benefits. Our results represent an important contribution to the ongoing debate around autonomy of independent professionals: the latter are either presented as highly autonomous workers benefitting from the flexibility of their work arrangements or, conversely, associated with precarious work arrangements and difficult working conditions. Our results provide a nuanced typology of empirical situations, overcoming such a dichotomic vision of nonstandard work arrangements. [less ▲]

Aquaponics is the association of fish and plant farming, exploiting the natural phenomenon observed in aquatic ecosystems. The microbiota transforms the fish waste into different chemical forms that are less toxic for fish and very suited for hydroponic plants culture. Due to its recent and quick development, aquaponics can now be found in a variety of areas of interest such as personal installations, education fields, private and public research projects and reached nowadays the food production at medium and large scales industries. The diversity found in these installations makes it difficult to identify the mechanisms that rule aquaponics and to generalize the findings to other systems. Few researches established the equations that govern the behaviour of one particular system, in order to estimate the productions and to apply sensitivity analysis. These models often satisfy the goals of the developers but cannot be applied to different system setups. In this context, a generalist model is being developed for aquaponics. The equations are based on aquaculture, hydroponics and aquaponics researches and are implemented using an object-oriented programming in order to generate a completely generic model. The European Smart Aquaponics Project provides numerous systems with different architectures. All these installations are equipped with a full set of aquaponics sensors to generate a strong aquaponic database that will be used for model development. The computed outputs are various and new ones are regularly added to keep pace with the continuous development of aquaponics. In this case study, the model has been applied to an experimental setup to illustrate the basic calculated parameters such as the dynamical behaviours of: the water volumes and several nutrient concentrations, the vegetal and animal biomasses, the water consumption, a few economic criteria, etc. [less ▲]

Drawing on archival research at the Billy Ireland Cartoon Library (Columbus, OH), this paper examines scrapbooks of collected comics and examine the stakes they rise when it comes to fandom studies and understandings of bedephilia practices. It argues that scrapbooks—as individual objects constituted of clipped-out fragments—undercuts our traditional conceptions of fandom (as an intensely networked and organized phenomenon), of bedephilia (as a movement militating for greater cultural recognition), and of collecting practices (a gendered practice in the US and one that emphasizes pristine). Scrapbooks are thus understood as a key and early "archival genre" that in itself constitutes a mode of knowledge and transmission for comics culture. [less ▲]

This paper is seeking to understand the conditions under which more inclusive forms of social dialogue might be developed in order to meet the basic needs of autonomous workers (Heery et al., 2004) in terms of security, human capital and job-matching in three contrasted institutional contexts: Belgium, France and the Netherlands. We thus adopt a neo-institutionalist stance by considering the specificities of each national labour market and the kind of institutional innovation likely to be developed accordingly. The renewal of the social dialogue for autonomous workers in a more inclusive perspective is analysed through a multiple case study design in the aforesaid contexts. This paper draws a picture of the factors likely to explain the implementation process of initiatives whose main aim is to secure the professional paths of autonomous workers, by analysing the functional equivalents and the collective capabilities they propose in each national context.

The current literature regarding expertise has relatively left aside the proactive role of experts in crafting their recommendations and developing useful practices in order to influence the decision-making process. This paper intends to fill in this gap by analysing the expertise that shaped NATO’s 2016 decision to launch four battalions in the Baltics in order to deter a newly assertive Russia. Doing so, this paper argues that relevant expertise for policy relies on two elements: a common discourse between think tanks and decision-makers and a set of ‘good’ practices on the side of the think tanks. Research question: What are the practices and discourses that allow for policy institutes to be considered as provider of credible knowledge? The first part of this paper relies on interviews and focuses on the different practices mobilised by think tanks in order to have their expertise considered relevant. The second part of this paper provides a discourse analysis of the reports published by think tanks prior to the Warsaw Summit (2016). The discourse analysis will be both inductive, with a special focus on recommendations provided by think tanks and deductive following concepts of critical geopolitics. [less ▲]

Grands mélomanes et protecteurs de musiciens méconnus, les princes-cardinaux Alessandro d’Este (1568-1624) et Maurice de Savoie (1593-1657) occupent une place toute particulière dans le paysage culturel romain entre 1620 et 1627. En effet, ces prélats ont contribué à façonner la géographie urbaine, sociale et musicale de Rome à travers les espaces de sociabilité qu’ils ont créés ou fréquentés (palais, chapelles, églises, places, jardins ou encore villégiatures). Ces lieux étaient le théâtre d’une vaste activité musicale et culturelle grâce à laquelle se nouaient réseaux ecclésiastiques et réseaux séculiers dans un but d’affirmation politique, sociale et de l’identité nobiliaire. Ces cardinaux ont ainsi favorisé la production d’événements artistiques, miroirs de leur magnificence, ainsi qu’une circulation musicale singulière (musiciens, répertoires et styles musicaux, instruments de musique) entre leurs nations d’origine et la Ville éternelle. La présente communication propose d’étudier les significations culturelles et sociopolitiques des pratiques musicales qui s’inscrivent dans l’espace urbain. Pratiques musicales que l’on peut comprendre en tant qu’expérience musicale collective insérée dans un dispositif politique. Notre hypothèse est que l’expérience musicale, plus que les autres arts, dépasse sa fonction ornementale, qu’elle est partie prenante et agissante dans le « Grand théâtre du monde ». Ainsi, cette approche, à l’intersection de l’histoire sociale et de l’histoire culturelle, vise à penser l’histoire de la musique comme celle de l’influence sociale des évolutions des formes culturelles.

Contemporary health policies constitute a real challenge in terms of collaborations, in the sense that they request cross-sectoral or cross-organisational collaborations (Clavier & Gagnon, 2013; Crosby & Bryson, 2010) as an answer to complex societal problems (Daviter, 2017). Beside this, those new policies also show an evolution in the policy piloting process as an increasing responsibility is delegated to field actors for interpreting those policy plans, strengthening the role of local communities within the production of public action (Bureau & Sainsaulieu, 2011; Dubois & Orianne, 2012; Genard, 2007). Those new health policies open the doors for the emergence of new intermediary professional roles, including the network coordinators. With this paper, our objective is to empirically illustrate and understand those coordinators’ place and role in the Belgian forensic mental health (FMH) policy piloting and implementation processes. The FMH policy shows a clear evidence regarding this twofold trend. Six mandated local networks gathering local stakeholders were created in order to (1) organise the development of (cross-) sectoral collaborations as well as to (2) implement the policy vision at the local level. For each network two coordinators were mandated by the public federal authorities. This paper is based on a qualitative research combining three different methods of data collection. It includes policy and network document analysis, thirty-five semi-structured interviews with stakeholders from the FMH field and fifteen observations of (federal and network) meetings. This methodology allowed us to follow the implementation and construction processes of the FMH policy plan since 2016 at different levels of action. Our research allowed us to understand that FMH coordinators play a key role regarding the twofold trend of contemporary health policies. The paper will show that they are sorts of “reform leaders” (Denis & Van Gestel, 2015), responsible for managing the implementation process. Each coordinator is both the “delegated translator” (Thunus, 2014) of a policy plan as well as the local stakeholders’ spokesperson. Furthermore, as for middle managers and boundary spanners, they are responsible for disseminating new ideas and knowledge across organisational and sectoral boundaries (Kimble, Grenier, & Goglio-Primard, 2010; Oldenhof, Stoopendaal, & Putters, 2016; Pichault & Schoenaers, 2012; Radaelli & Sitton-Kent, 2016). Coordinators are thus “more than passive linking pins, transmitting senior manager instructions unquestioningly down the organization” (Harding et al., 2014, p.1215). This knowledge translation and sharing allow to articulate the different stakeholders’ visions, interests and to ‘align among differences’ (Quick & Feldman, 2014). Horizontally, the coordinator draws linkages between local actors, allowing him to produce a coordinated action. Vertically, the coordinator forms the link between street-level implementation actions and formal stated policy (Gofen, 2013) and thus ensure a continuous mutual adaption between ‘what is wanted’ and ‘what is done’. In conclusion, we aim to demonstrate that the coordinator thus emerges as one of the key players of contemporary policy making and implementing processes, to whom a certain political responsibility is indirectly transferred since they directly influence the production and the structuring of the public action.

Likewise to other authors, Rutherford (2010) states that “these last two decades there has been a convergence between mental health and criminal justice policy, legislation, systems and practice, [...] boundaries between the two systems are becoming increasingly blurred.” With this communication, we suggest to approach this question by replacing it in the context of the internment field, which currently undergoes a process of deep reorganisation and transformation. Historically, the Belgian Internment measure has been oscillating between justice and health since the first regulations of the measure (Cartuyvels & al., 2010). However, the underlying logic of the approach was mainly based on a model in which the protection of society was predominant. This perspective leads to inadequate treatments toward this group of patients and leads to multiple convictions of the Belgian state by the European Court of Human Rights (ECHR). Following this, a new legislation came into effect on October 1st, 2016. Regarding the political arena, several policy initiatives have been directed toward reorganising the care offer for MIOs. In 2016, this political will became concrete through the Masterplan Internment at the initiative of the Ministry of Public Health. With the arrival of those new legal and political regulations, we observe a paradigm shift in the way the approach toward this public is conceptualised in Belgium: the notions of social reinsertion and care recovery through adapted and individualised care trajectories are becoming central. The legal framework as well as the policy plan constitute new hybrid devices (Pans & al., 2016) whose objective is to stimulate collaborations between the mental health and justice sectors professionals in order to foster the MDOs reintegration pathway. With those regulations emerged new hybrid professionals, as for example local network coordinators and healthcare mobile teams, positioned at the crossroad of justice and mental health fields, moving through care and justice spaces and places (prisons and mental health facilities). By penetrating both sectors through active collaboration with professionals from both sectors, they play a role of boundary spanners and knowledge brokers, connecting together several entities previously separated by a boundary – organisational or sectoral (Kislov et al. 2017; Williams, 2002). Since these new regulations, we perceive an important acceleration of collaborations between mental health and justice professionals – justice assistants, mobile teams, psychiatrists, staff of psychiatric hospitals and other mental health facilities, and so on. We argue that those new hybrid devices and professionals play a key role within the opening up of the sectors and come to foster the blurring of mental health and justice sectors’ respective boundaries. Therefore, we would like to ask to which extent does this hybridisation pervades health and justice professionals’ discourses and representations? Regarding the empirical material, three different methods of data collection have been combined. It includes document analysis, more than fifty semi-structured interviews with stakeholders from both fields and observations of meetings gathering policy makers and/or professionals from both field. We suggest that this methodological triangulation was necessary to understand the ongoing transformation of cross-sectoral collaborations in a more comprehensive way. [less ▲]

If positive parents’ reading attitudes are related to better pupils’ reading achievement, one can wonder by which process this relation occurs? With PIRLS 2016 data, for French speaking part of Belgium, our objective is to better understand the link between parents’ reading attitudes and pupils’ reading achievement. Our hypothesis is that parents’ reading practices impact pupils’ motivation which in turn is linked to pupils’ reading achievement. Regression analysis shows that, socio-economical status taking into account, reading self-concept and intrinsic motivation are mediators of this relation while instructional engagement is not.

Research question and review of literature: The paper answers the following question: “How does the level of workers’ participation in governance, ownership and profit sharing affect the expected survival of worker cooperatives?”. As such, this research focuses on the nexus between workers’ participation and worker cooperatives (WCs)’ performance. Theory identifies three channels through which workers’ participation affects, either positively or negatively, company's performance: the workers’ productive capacity (Park, Kruse, & Sesil, 2004), the workers’ effort (Bonin, Jones, & Putterman, 1993) and the company’s organizational effectiveness (Hansmann, 2000). From an empirical point of view, in comparison with conventionally owned firms (CFs), previous studies have generally assessed that early survival of WCs meets or exceeds CFs’ and that they demonstrate a median lifespan as long or longer than CFs (Pérotin, 2004 and Burdín, 2014). Various studies also tend to suggest a positive effect of workers’ participation on productivity. However, like CFs, WCs suffer from an elevated probability of not-surviving in their early years (Olsen, 2013) and the positive effect of workers' participation on productivity seems to vary depending on the type of workers’ participation analyzed. Moreover, evidence of a lower economic performance of WCs does exist as well, especially for undercapitalized WCs and in certain industries (Defourny, 1990). Heterogeneity of the studies contexts and methods as well as divergences in results support the necessity of further research on WCs’ performance and expected survival. Methodological approach: The methodology used consists in the estimation of a survival function for more than 2500 French WCs from 2006 to 2012. By including independent variables measuring the level of workers’ participation in governance, in ownership and in profit sharing, estimations explain the relation between the various types of workers’ participation and the probability to survive of a WC. Only few authors, among which Pérotin (2004), Olsen (2013) and Burdín (2014), have used the estimation of a survival function in the framework of WCs’ performance. Main argument: In comparison with the method generally used to evaluate the productivity of WCs, i.e. the estimation of a production function “augmented” by variables apprehending the different forms of participation, the estimation of a survival function avoids the problem of endogeneity between performance and level of involvement. Therefore, the research conducted improve the robustness of the observed effects. Main conclusions and their relevance to an international audience: Through the research, we apprehend better potential advantages and weaknesses of the specificities of the WC system and in particular, the effects of workers’ participation in governance, ownership and profit-sharing on their cooperative’s survival and performance. In an overall search for a greater pluralism of economic models, the progress of the ongoing debate on the effects of workers’ involvement appears to be crucial. Main references: Bonin, J.

The real or perceived proximity to death often results in a non-ordinary state of consciousness characterized by phenomenological features such as the perception of leaving the body boundaries, feelings of peace, bliss and timelessness, life review, the sensation of traveling through a tunnel and an irreversible threshold. Near-death experiences (NDEs) are comparable among individuals of different cultures, suggesting an underlying neurobiological mechanism. Anecdotal accounts of the similarity between NDEs and certain drug-induced altered states of consciousness prompted us to perform a large-scale comparative analysis of these experiences. After assessing the semantic similarity between ≈15,000 reports linked to the use of 165 psychoactive substances and 625 NDE narratives, we determined that the N-methyl-D-aspartate (NMDA) receptor antagonist ketamine consistently resulted in reports most similar to those associated with NDEs. Ketamine was followed by Salvia divinorum (a plant containing a potent and selective κ receptor agonist) and a series of serotonergic psychedelics, including the endogenous serotonin 2A receptor agonist N,N-Dimethyltryptamine (DMT). This similarity was driven by semantic concepts related to consciousness of the self and the environment, but also by those associated with the therapeutic, ceremonial and religious aspects of drug use. Our analysis sheds light on the longstanding link between certain drugs and the experience of “dying“, suggests that ketamine could be used as a safe and reversible experimental model for NDE phenomenology, and supports the speculation that endogenous NMDA antagonists with neuroprotective properties may be released in the proximity of death.

Polycarbonates (PCs) and polyurethanes (PUs) belong to some of the world-leading polymers found in many of our daily life applications. PCs are mainly produced by polycondensation of alkylcarbonates/phosgene derivatives with diols at high temperature, or by ring-opening polymerization of 5- or 6-membered cyclic carbonates while PUs are industrially made by polyaddition of diisocyanates with diols. Recent developments in the PUs field deal with the polyaddition of 5-membered dicyclic carbonates with diamines, but this polymerization is much slower compared to the isocyanate route and gave regio-irregular polymers of low molar mass due to the asence of selective ring-opening and the occurrence of side reactions. The polyaddition of dicyclic carbonates with diols would also be attractive to prepare PCs but is challenging due to the poor reactivity of the 5-membered cycles towards alcoholises. Until very recently, using a single 5-membered dicyclic carbonate platform to access various polymer families remained an elusive endeavour. In this talk, we will describe an innovative approach for the preparation of new families of PCs and PUs, by the facile room temperature polyaddition of novel activated CO2-sourced 5-membered biscyclic carbonates with diols (for PCs) or diamines (for PUs). These novel cyclic carbonates are prepared by organocatalyzed carboxylative coupling of CO2 with dialkynols. Although PCs require some organocatalyst to be produced, PUs synthesis do not require any activation. Moreover, this process allows for the synthesis of regioregular functional polymers free of defects and displaying high molar masses (Mn up to 100 kg/mol in some cases). The origin of this unprecedented reactivity will be explained as well as its impact on the polymer structure. We will also show that these novel CO2-sourced monomers can also be exploited to expand their scope of valorization to a fourth family of novel functional polymers, by tuning the nature of the comonomer. We believe that this platform of novel monomers is opening new perspectives in the facile production of novel and/or existing world-class relevant polymers by valorizing CO2 as a renewable feedstock.

Home chemotherapy (HC) services aim to assist cancer patients enabling them to remain comfortable at home. This is currently a rising trend, and it should be encouraged when the patient's conditions are favorable. HC services imply both the production and the administration of drugs to patients. These activities are run in parallel and must be carefully synchronized due to short lifespan of drugs and limited resources. In order to efficiently plan these activities at the operational level, two well-known and hard problems, scheduling and routing, need to be solved as a whole, rising challenging synchronization issues. We consider a set of patients that must be visited by a set of nurses for administration of personalized drugs. Nurses come back to the hospital in order to get newly produced drugs thus perform multiple serving trips. The drug is produced right before delivery by a set of the technicians in the hospital pharmacy. We propose to use a large neighborhood search heuristic that iteratively removes and reinserts operations to create new solutions. Three destroy and recreate operators are considered: 1) production operations are removed and reinserted 2) drug administration operations are removed and reinserted 3) both types of operations are removed and reinserted. Ad-hoc mathematical programming based operators are developed to re-optimize the current solution. The algorithm is tested on new instances created based on discussion with hospitals in Belgium.

The present research aims at investigating in details the reaction between carbon dioxide and a diol to afford cyclic and acyclic carbonates in moderate to good yields. Thanks to its chemical structure, CO2 has been identified as a promising reagent for the synthesis of organic carbonates as it is non-toxic, cheap and an abundant C1 renewable feedstock, and could potentially replace phosgene based carbonates produced industrially. Prior research has been focused on the epoxide/CO2 coupling to afford cyclic carbonates in good yields. Yet, this coupling suffers from limitations such as restricted substrates and exclusive synthesis of 5-membered cyclic carbonates. In order to extend the products availability through Carbon Dioxide Utilization, more recent research has been carried out with new substrates such as the use of diols. Although many different catalysts and reaction routes have already been investigated, efforts are still needed to identify cheaper and more efficient protocols for the selective synthesis of cyclic and acyclic carbonates from the coupling of CO2 with diols. In this context, the use of organic bases/alkylating agent dual system as promoters and low pressure and temperature conditions (P<1MPa, r.t) seem to be a good alternative to afford organic carbonates. The present work aims at providing, thanks to an in-situ ATR-IR spectroscopy monitoring, a detailed understanding of the synthesis of propylene carbonate from propylene glycol and CO2 promoted by DBU and the addition of alkyl halides. This analytical tool enabled to identify several reaction intermediates and to determine how the kinetic profiles, the reaction yields, and the selectivity of the reaction evolves with various parameters (pressure, temperature and nature of the base and alkyl halide). Thus, several experimental conditions have been tested as well as various alkyl halides in order to understand in details the effect on the selectivity and the efficiency of the reaction. Different substrates were also tested such as 1,x diols (2 ≤ x ≤ 4) and Isosorbide. The selectivity toward cyclic or biscarbonated compounds is discussed. Density Functional Theory (DFT) was also performed in this work to understand and validate the reaction pathways proposed via ATR-IR monitoring. Structures of transition states were optimized and comparisons between several reagents and/or paths were calculated, giving capital information about further enhancement of the CO2-diol conversion into carbonates.

While the global tendency of urbanization is stills increasing, cities’ growth pattern has been transformed in the las decades through the emergence of megacities or metropolitan regions. Here, defining a clear border is becoming more complex and the traditional binary conception of rural versus urban has become obsolete. Due to the hybrid condition of these new territorial configurations, an extraordinary collection of concepts are currently used to describe them; in some cases with ambiguity or as synonyms to describe this area as a unique notion, but in other cases used as terminology that seeks to capture the most outstanding features of these diverse geographies. This contribution aims at establishing new precisions about the most recurrent terms-concepts used in the scientific literature to describe the urban-rural gradient in a Latin-American context (Periphery, periurban, suburban and rurban areas), developing a sort of catalogue that clarifies and visualizes these territorial realities in a technical and scientific language. The contributions of Latin American studies have been built on the demand for recognition of their reality as different from the European or North American ones. As a methodology, a Citation Frequency Index has been calculated from 64 scientific articles and -specifically- in 598 quotes. Through it, the most outstanding attributes for each concept have been identified and systematized. A total of 50 attributes were identified and organized in 8 categories: Morphology, Functionality, Dynamics, Demography, Social and/or Cultural Conditions, Politics, Environment and Economics. From these, morphology (20%) and function (29%) showed to be the most recurrent and relevant characteristics for describing a territory. This exercise of classification represents a first theoretical finding for Latin-American realities and an applicable conceptual proposal that can be useful, as a guide, for understanding the contemporary patterns of urbanization in other realities.

The proposed study mobilizes written sources from the French State (general information, prefectures). These have so far identified 302 Kurds from Turkey and 2,449 Turks who have passed through, settled or been born in western France since the 1970s. These sources make it possible to understand the specific characteristics of Kurdish migration from Turkey, their settlement in a territory qualified as a “low immigration area”. Their journeys and migration patterns showed growing correlation and links with those of former economic migrants from Turkey in the 1970s, whether Turks or Turkey-based Kurds. This observation then triggers further questioning and investigations related to the relations between these first generations of migrants and the more recent Kurd refugees (for instance, where did they come from and where did they live in France?). The proposed study examined the various migration strategies and networks (political, family...) developed by Kurdish asylum seekers. In addition, there are the power games and tools available to the Kurds to assert their identity in order to obtain “refugee” status and no longer be “invisible”. This question of invisibility raises questions about how and why some Kurds tended to express or hide their identity during their administrative procedures. [less ▲]

The current stimulated atomic diffusion in YBa2Cu3O7 superconducting bridges is investigated. A superconductor to insulator transition can be induced by direct current controlled electromigration process whereas partial recovery of the superconducting state can be achieved by inverting the polarity of the bias. Interestingly, the temperature dependence of the current density Jem(T), above which atomic migration takes place intersects the critical current density Jc(T) at certain temperature T*. Therefore, for T<T* the superconducting dissipative state cannot be accessed without leading to irreversible modifications of the material properties. This phenomenon may also become an important mechanism of local sample deterioration in high critical temperature superconducting films abruptly penetrated by thermomagnetic instabilities. [less ▲]

The heat shield of high speed reentry spacecraft is often made up of porous ablative thermal protection materials (TPMs) that can accommodate high heating rates and heat loads through phase change and mass loss. When the temperature increases, those materials absorb heat and start to pyrolyze, releasing gases that interact with the surrounding flow. Modeling the species production and the material decomposition rate is important for their use in numerical simulations for the robust determination of heat shield thickness. To this end, pyrolysis experiments have been performed on TPMs in order to determine the kinetic parameters of chemical laws that govern mass loss and species production rates [Wong et al., Polym. Degrad. Stabil., 112:122–131, 2015; Bessire and Minton, ACS Appl. Mater. Interfaces, 9:21422—21437, 2017]. Samples are heated in a furnace and the mass loss is measured while the species produced are collected. In the present work, we investigate parameter calibration of law governing the thermal decomposition of TPMs in a Bayesian inference framework using experimental data of the evolution of gas species production over time. We discuss the problem of highly correlated parameters and we propose a reparametrization of the equations that lead to a scaled posterior density function which is more efficiently sampled using a multivariate Gaussian distribution in the random walk Metropolis-Hastings algorithm. We study the influence of reducing the available data set in order to avoid over-confidence in the parameter values. To that aim, we propose to extract important features based on zero-gradient and inflection production rate temperatures or temperature of reaction. Finally, measurement noise and model error norm appear to be critical in the inference results. Measurement noise tending to zero can lead to regions in the data set that are over-constrained and we propose different strategies in order to relax the problem in regions of smaller significance and we apply several norm for the model error definition.

Primates spend half of their lives at sleeping sites and should select them carefully. Macaques usually use about thirty sleeping sites and their selection respond primarily to predation avoidance. We studied a northern pigtailed macaques troop sleeping sites selection pattern in a degraded forest fragment, the Sakaerat Biosphere Reserve in Thailand. We identified 107 sleeping sites with only 15 reused sites selected at random. Using resource selection function, we found that macaques sleeping site selection is best explained by proximity to feeding areas. Preliminary study of habitat characteristic suggests that there is no structural difference between selected and available sleeping trees in the troop home range. In degraded habitat where forest structure does not offer optimal sleeping trees against predators and with scattered fruit tree distribution, macaques seem to favor strategy based on food resources proximity. These results highlight impact of habitat degradation may have on sleeping site selection in a flexible species. [less ▲]

(Extrait introduction) Je voudrais commencer en partant d’une œuvre présentée par Sissel Tolaas en 2007 (artiste norvégienne vivant à Berlin / artiste-chimiste comme la plupart des artistes qui opèrent ou qui sévissent dans le champ de l’art olfactif) , une installation qui porte comme titre : The Smell of Fear / the Fear of Smell (l’odeur de la peur, la peur de l’odeur). Ici Sissel Tolaas a utilisé principalement des odeurs de transpiration/sueur captées à même le corps grâce à des bandelettes imbibées de graisse (le gras comme vous le savez absorbe les odeurs et les garde très efficacement) sur 21 personnes phobiques en situation de contact avec l’objet de leur phobie. Je voudrais m’y intéresser quelques instants pour deux raisons. Pour les enjeux thématiques/critiques que l’artiste mobilise avec ce travail : son installation met en scène et spatialise notre rapport complexe aux odeurs, et en particulier aux odeurs corporelles des autres, puisque dans ce registre le malaise est souvent lié à l’altérité et à son caractère envahissant (des études ont montré par ex qu’on serait moins dérangé par des odeurs émises par quelqu’un d’autre mais qu’on pense provenir de nous que par nos propres odeurs qu’on attribuerait à tort à l’autre). Comme le suggère le titre de l’installation, notre rapport aux odeurs serait traversé par la peur du corps de l’autre en tant qu’il est susceptible de déborder ses limites et de faire effraction dans notre espace vital privé. De manière générale, Sissel Tolaas, qui travaille en laboratoire avec l’équipement sophistiqué d’une chimiste, crée des réactions chimiques qui ont pour caractéristique de produire des odeurs difficiles à supporter : par ex. le Musée de l’armée allemande de Dresde lui a demandé de reconstituer l’odeur des tranchées de la première guerre mondiale, ce qu’elle a fait en produisant un « mélange de charogne, de sang chaud, de transpiration, de poudre à canon, de terre humide et de moisissure », pour un résultat –à en croire ceux qui en ont fait l’épreuve– pratiquement insupportable au nez et à l’estomac. En même temps, son travail manifeste une volonté de neutralisation de l’axiologie des odeurs : elle manipule des odeurs difficiles (odeurs de cheveux sales, de transpiration) dont elle choisit de considérer qu’elles ne sont pas qualifiables en tant que telles de bonnes ou mauvaises (elle-même dit ne pas vouloir porter de parfum pour ne pas camoufler son identité olfactive) . Mais l’œuvre m’intéresse aussi dans son dispositif, dans son format, dans sa mise en espace : le spectateur, pour profiter de ces odeurs, doit non seulement s’approcher du mur, s’engager physiquement dans une relation de proximité avec l’odeur, mais également la faire advenir cette odeur. Et seul le contact physique direct possède ce pouvoir. Autrement dit, pour percevoir les odeurs prises dans le mur, il faut gratter, frotter, y mettre les mains, en approcher son nez, entrer en contact (sur le même principe que les livres odorants pour enfants). Les odeurs sont encapsulées dans le mur de l’espace d’exposition, on ne les libère qu’en le frottant. [less ▲]

We demonstrate the in situ engineering of superconducting nanowires via modulation of material properties through high applied current densities. We show that the sequential repetition of such customized electro-annealing in a niobium nanoconstriction can broadly tune the superconducting critical temperature Tc and the normal-state resistance Rn in the targeted area. Once a sizable Rn is reached, clear magneto-resistance oscillations are detected along with a Fraunhoferlike field dependence of the critical current, indicating the formation of a weak link with adjustable characteristics. Applying this method to aluminum nanoconstrictions, it is possible to modify their geometry and consequently their weak links’ properties beyond the limit of current lithography techniques. Furthermore, conducting parallel electromigration in aluminum SQUIDs allows us to investigate the evolution of the superconducting properties of the SQUID as function of the cross section of the weak links and eventually access a regime where the SQUID can be operated in the dissipative state. We will also discuss the possibility to change the local oxygen doping in constrictions made of High-Tc materials. [less ▲]

Iron tungstate Fe2WO6 attracts interest due to its photoelectrochemical and magnetic properties. On the one hand, Fe2WO6 is studied either as a photocatalyst for degradation of environmental pollutants [1,2] or as a photoanode for water oxidation in tandem devices [3-4]. On the other hand, some magneto-dielectric properties [5] have been reported, confirming that further work is needed to investigate the magnetic and electric properties. Indeed, Fe2WO6 iron tungstate exists as three crystal structures with different organizations of the FeO6 and WO6 octahedra [6-8]. In the present work, we have clarified the conditions of polymorphism using a complete set of the three polymorphs as single-phase products. In particular, a spray-drying route from aqueous solution had to be developed for the synthesis of the low temperature α polymorph. We have revised the structural model for this α-polymorph, solved the heretofore-unknown structure of the β-polymorph and compared magnetic properties through bulk magnetic measurements and preliminary neutron diffraction results. We also report on the influence of the Fe/W ratio using a combination of X-Ray diffraction, 57Fe Mossbauer spectroscopy, scanning electron microscopy and ICP-OES quantification. [less ▲]

Open Science (OS) is a global movement reflecting in the scientific community a growing awareness of the importance of transparency and sharing. It promises to be a victory for cooperation over competition. However, to succeed, it will have to overcome a deep human instinct of competitiveness. This inclination is fostered by an evaluation method based essentially on competition. It is very difficult today for early career researchers to adhere to the principles of OS as long as they keep being evaluated according to metric criteria that are most often indirect and reflect more the publisher’s prestige than the candidates’ qualities. Being trained and judged like jockeys in a horse race does not encourage them to take the time necessary for serenity in their research process nor to exchange and share honestly with their peers. A qualitative multi-criteria approach, OS-CAM: Open Science Career Assessment Matrix is now proposed. It is based not only on scholarly productivity but also on qualities expected in OS. It is adjustable according to the career level and to the field of research. It awaits to be used globally and fairly. [less ▲]
