El entusiasmo académico por la diplomacia pública no se refleja en una atención específica a la misma en las estrategias de política exterior de la Unión Europea (UE). Sin embargo, su presencia se revela en múltiples iniciativas en las que los agentes no gubernamentales tienen un papel clave como receptores o actores: actividades de cooperación, de intercambio, informativas. La diplomacia pública es una actividad diplomática y de comunicación política internacional que busca influenciar a públicos extranjeros con el fin de contribuir al logro de objetivos de política exterior y/o generar una imagen positiva. Funciona como una herramienta efectiva para movilizar recursos de poder blando, un poder basado en la atracción y la persuasión que se produce de modo indirecto cuando los actores políticos movilizan recursos como la cultura, los valores, las instituciones y las estrategias de política exterior. Pese a la crisis económica, la UE conserva un gran potencial de poder blando. Por eso, y dada la relevancia de Brasil como socio prioritario en la región latinoamericana, este artículo investiga qué diplomacia pública ha desarrollado la UE en este país los últimos tres años, así como su correspondencia con el cuerpo teórico sobre esta actividad.

Nine neurodegenerative disorders, referred to as polyglutamine diseases and including Huntington’s disease, are associated with the abnormal expansion of a polyglutamine tract inside nine unrelated proteins. This polyQ expansion is thought to be the major determinant in the development of neurotoxicity, triggering protein aggregation into amyloid fibrils. A large body of evidence however indicates that non-polyQ regions modulate the aggregation process triggered by polyQ expansions. The interplay between the polyQ tract and non-polyQ regions is complex and still not fully understood. In order to better understand it, we previously designed and characterized model polyQ proteins made of the beta-lactamase BlaP and a 23, 30, 55 or 79Q tract inserted in position 197 or 216. These chimeras recapitulate the aggregation properties of polyQ disease-associated proteins: there is a Q threshold for the formation of amyloid fibrils, and above the threshold, the longer the polyQ, the faster the aggregation. Moreover, the structure of BlaP (native or unfolded) and the position of insertion of the polyQ tract (197 versus 216) influence their aggregation properties. In this work, (i) we will discuss the role of the conformation of the host protein, BlaP, and of the location of the polyQ within BlaP on the different phases of amyloid fibril formation, the nucleation and elongation steps, using mainly quartz crystal microbalance (QCM), atomic force microscopy (AFM) and dynamic light scattering (DLS); and (ii) we will investigate the precise aggregation threshold and the modulating role of the N- and C-terminal polyQ flanking sequences in position 197 of BlaP by creating and characterizing new chimeras containing intermediate length polyQ tracts in position 197, or polyQ tracts inserted between two cleavage sites in position 197, respectively. Our results highlight a linear dependence of the polyQ length on the elongation rate whatever the insertion site and the conformation of BlaP. These two parameters however drastically influence the ability of a polyQ tract to trigger the nucleation and the elongation steps of amyloid fibril formation. Finally, we observed that the propensity to form amyloid fibrils and its rate seems to be largely dependent on the polyQ length and on the polyQ flanking sequences. Altogether our results contribute to identify the important species and elements (polyQ or non-polyQ regions, monomers, oligomers or fibrils) during the aggregation process into amyloid fibrils to interfere with the latter associated with neurotoxicity.

Introduction. Nowadays, the interest in foam materials is growing in several engineering fields [1]. Foams can exhibit a nonlinear mechanical behavior [2], which is highly depen- dent on their microstructure [3]. Thus designing foams with specific mechanical properties can be very challenging. The present contribution is part of the ARC-Bridging project [4], whose objective is to predict the mechanical behavior of complex microstructured mate- rials via numerical simulations. A possible classification of foam models into two groups is: random models and deterministic models [5]. The random models frequently require statistical estimations of their parameters [6], whereas the deterministic models generally require numerically expensive image analyse. Indeed, classical analysis steps involve a distance tranform, a watershed and, optionally, a h-minima transform [5, p. 22], which can be computationally demanding [7, 8, 9]. Contribution. In the present Laguerre–Voronoi tessellation model, the image analysis part neither involes the watershed transform, nor the h-minima transform. Instead, fol- lowing the original idea of A.M. Lopez-Reina et E. Béchet [10], these two transforms are respectively replaced by a Hessian-based removal of spurious extrema and a clustering of the remaining maxima. This substitution allows the processing of large 3D-images by slices, i.e. “streaming”. The only limitation is enforced by the distance transform: the “feature” voxel of a given voxel should belong to the same slice. For foam images, this condition is fulfilled as long as the slice’s thickness is larger than the maximal foam cell’s size. Conclusion and perspectives. The aim of this contribution is to provide an efficient tessellation model for tomographic images of foams. From input tomographic images, this model provides a geometry model which will be used as an input for finite element simulations under the ARC-Briding project [4]. Simulation results will be compared with experimental measures. [less ▲]

Public diplomacy is a promising activity for international political actors to promote a positive image abroad. It also provides opportunities for dialogue, understanding and mutual benefit when communicating and addressing challenges. Within the European Union (EU), the Lisbon Treaty and the European External Action Service (EEAS) have given a new strength to foreign policy. The EEAS, launched in December 2010, is the EU's main institution for public diplomacy. Argentina, Brazil and Mexico are relevant Latin American partners for the EU because of their size, population and political and economic potency in the region. This paper aims to answer the following questions: What is the context of EU relations with Argentina, Brazil and Mexico during the period of study (2011-2013)? What have been the EU's foreign policy and strategies towards these countries? How have public diplomacy and the work of the EEAS in these countries supported the objectives and strategies? This research includes information gained through the consultation of publications, official documents and interviews with personnel from the EEAS, both in Brussels and in the EU delegations in Latin America.

Since the end of the civil war in 2009, rural Southern Sri Lanka is facing growing tensions between fast economic development and the conservation of biodiversity, which contributes to the notoriety of the island. In order to preserve the green areas of the country, both the government and international institutions have made great efforts to implement projects combining biodiversity protection and poverty reduction as their objectives. Within that context, this paper focuses on a specific category of stakeholders, emerging from the implementation of the aforementioned projects: a wide range of intermediaries between local communities and the State, or international institutions. Based on an ethnographic study of two protected areas in Southern Sri Lanka, the paper will examine the role of those intermediaries in the implementation of environmental governance models and ideologies in local arenas. I will also analyze the complex relationships between those brokers and other categories of individuals or groups within the community: people living in protected areas, traditional figures of power, social and political elites, etc. Using fieldwork illustrations, I will stress how the emergence of brokers and intermediaries in the context of nature conservation may lead to the reorganization of social and political relationships at the local scale.

The purpose of this talk is to present a novel approach to detect differential item functioning (DIF) among dichotomously scored items. Unlike standard DIF methods that perform an item-by-item analysis, we consider a logistic regression model including item-group interaction (i.e. DIF) effects of all items simultaneously. The method is based on penalized maximum likelihood estimation of a model with a lasso penalty on all possible DIF parameters. Optimal penalty parameter selection is investigated through several known information criteria (such as AIC and BIC) as well as a newly developed weighted alternative. A simulation study was conducted to compare the global performance of the suggested “lasso DIF” method to the logistic regression and Mantel-Haenszel methods, and to evaluate the different optimal penalty parameter selection methods. It is concluded that for small samples the lasso DIF approach globally outperforms the logistic regression method, and also the Mantel-Haenszel method, especially in the presence of item impact, while it yields similar results with larger samples.

Animal-mediated seed dispersal is an essential ecological process in the tropics. Among African primates, the critically endangered western lowland gorilla (WLG) seems to fulfill many characteristics of an effective seed disperser. WLG preferentially disperses species of various seed-size into open canopy habitats suitable for seedling growth. However, few studies have addressed the effects of the passage through the digestive tract on germination. Thus, the effectiveness of WLG in ecological processes governing forest dynamics and regeneration is still poorly known. Seed dispersal by WLG was studied in Central Gabon and Southeast Cameroon. Dispersed seed were identified from fresh fecal samples. Comparative germination trials based on 5 treatments (seeds from fresh fruits, seeds from fresh fruits surrounded by pulp, seeds from fresh fruits with fecal matrix, seeds from feces and seeds from feces with fecal matrix) were realized for 13 species. We recorded germination success for all species and germination delay for 6 species. Our results suggest a neutral gut passage effect for 54% and positive effect for 40% of tested species. Germination success enhancement was linked to another factor than pulp suppression. For two species, pulp suppression enhanced germination success, but not gut passage. The presence of pulp or fecal matrix surrounding the seed seemed to longer germination delay, while gut passage would not fasten germination. Globally, we conclude that WLG dispersed seeds are not damaged by gut passage. Consequently, WLG is thought to provide effective ecological services that could be essential to the maintenance and the recovery of forest ecosystems. [less ▲]

Over the past decade, the Precision Livestock Farming (PLF) concept has taken a considerable place in the development of accurate methods for a better management of farm animals, as Precision Agriculture has done for crop production. Mass consumption mobile devices have nowadays the possibility to record accurately user movements with their Inertial Measurement Unit (IMU). We used iPhone 4S to detect accurately cattle behaviors such as grazing and ruminating with the aim of performing a precision grazing management on the near future. Results showed accuracies ranging between 84% and 100% when detecting these two major behaviors by analyzing recorded raw signals in the time-domain. Ongoing research tries to link these behaviors to different pasture characteristics and performs a refined signal processing analysis for a better monitoring of some possible behavioral changes.

Political careers have become more diversified in multi-level systems over the last decades. In ‘classic’ federations (e.g. the US, Canada, and Germany), regional offices have become attractive positions with the process of professionalization. In newly regional political systems (e.g. Belgium, Spain, and the UK), the regional level has been quickly perceived by ambitious candidates as a professionalized political arena. Overall, regional positions in multi-level contexts are no longer conceived as amateur positions or mere stepping stones towards the national level. Despite the growing literature on the topic, several methodological questions remain nonetheless opened. This paper discusses the benefits and limitations of a mix-methods research design relevant for the study of elites’ career patterns. Specifically, the paper presents how and why mixing two quantitative and qualitative methods: survival analysis and life story interviews (for the purpose of illustration, the paper relies on empirical data: 1.831 careers and 84 life stories). Firstly, I introduce separately the added-value of each research methods (I especially discuss the benefits of these approach to collect and analyze longitudinal data in a context of multi-level system). Secondly, I demonstrate how these two methods permit to better understand elites’ career patterns in the context of multi-level systems. [less ▲]

Men and women imagined the presence of the Man in the Moon in order to account for the spots in the full moon. There are a number of references to him (and sometimes to a woman) in English folklore and literature (seal of Walter de Grendon, nursery rhymes, Neckam, ME poem, Chaucer, Shakespeare…). He was thought to have been exiled there and carries a thorn bush on his back because he once stole thorns from hedges (or violated some religious commandment). There is a variant of the legend in Snorri: the moon-god Máni (ON ‘moon’) once took two children from earth when they were coming from a spring carrying a bushel and a pole on their shoulders; as can be seen from the earth, the boy and the girl are still in the sky and follow the moon. I want to argue that this familiar Scandinavian and English figure – but also present in France and Wallonia -probably derives from an ancient Germanic myth that developed slightly differently among the Northern and Western countries, and that the two traditions eventually merged due to the contacts between the Scandinavians and the English.

Reducing environmental impact, related regulations and potential for operational benefits are the main reasons why companies share their Returnable Transport Items (RTIs) among different partners of a closed-loop supply chain. This research deals with an inventory-routing problem with pickups and deliveries of RTIs. A mixed-integer linear program is developed and tested on small instances. To handle realistic large size problems, a clustering algorithm is coupled with a simulation model. This hybrid heuristic allows assessing the benefits of information and RTIs sharing among partners.

Introduction Termites are studied for many aspects of their biology. Historically known as pests in regard of human activities, these insects were more recently intensively investigated in the biofuel context. Symbiotic interactions occurring along the termite gut are of particular interest for both of these scopes. In this study we compared hindgut metaproteome of termites fed with an anti-termite treatment and an untreated diet. Material & Methods Termites were fed with Whatman paper for 84 hours. For untreated and treated diet respectively, paper was moisten with water and a sub lethal suspension of tannins associated with boric acid (BAT). Termite hindgut content proteome was extracted and digested. Peptides were analyzed through nano-LC-ESI-MS/MS using an Orbitrap analyzer. Proteins identification was realized by Mascot search in a homemade termite protein sequences database. Non redundant peptides with a score above identity threshold were blasted against NCBI nr database and results of this blast were analyzed using MeGAn 5. Results High resolution mass spectrometry allowed identification of around 1500 and 1000 non redundant peptides respectively for water and ABT treatment. Peptides were parsed following their taxonomic and functional attribution in order to highlight differences in hindgut metabolism such as cellulose digestion or detoxification process. Identification of ubiquitous proteins also revealed differences in symbiotic populations balance. Conclusions Despite the sub lethal concentration for the anti-termite treatment, significant perturbation of hindgut metabolism was observed. Tannins are slightly repulsive for termites compared to boric acid alone, and this has to be taken in account. These results will be completed with biochemical assays, microscopic observations and 2D-DIGE MALDI-TOF/TOF experiment, analyzing potentially synergistic effect between boric acid and tannins.

We examine the incentives of an internet service provider (ISP) to break net neutrality by excluding internet applications competing with its own products, a typical example being the exclusion of VoIP applications by a telecom company offering internet and voice services. We show that exclusion is not a concern when the ISP is a monopoly because it can extract the additional surplus created by the application through price rebalancing. By contrast, when ISP’s compete, in an attempt to differentiate, only one ISP will offer the app. Applying a no-exclusion rule in this case can lead to monopoly. [less ▲]

French futuristic novels tend to develop a wide range of representations regarding the book of the future as it is impacted by technical inventions, from the phone to the digital paradigm through photography and film: Albert Robida’s “phono-livre” (La Vie électrique, 1890), Octave Uzanne’s “storyographe” powered by electricity from the human body, Henri Allorge’s “bibliophone” (Le grand cataclysme, 1922), Léon Daudet’s “cinébiblat” and “cinélivre” (Le Napus, 1927), Maurice Renard’s telepathic book (Un homme chez les microbes, 1928) or even René Barjavel’s “télélecture” (Ravage, 1943) among others. It is well known that the historical antagonism between Science and the Humanities deeply influenced the disciplinary boundaries and the respective values of the two fields. But it also appears that such a disciplinary discussion does involve the issue of the material and tangible forms of the book considered as an object. Futuristic novels put a specific emphasis on the acoustic, visual and tactile avatars of the book within a sociocultural context characterized by the rise of Applied Sciences and media communication. Do these new media and formats compete with or complement to the former book patterns? Are such representations of the book as an audiovisual item some response to the predicted decline of the Humanities? Or are they rather a means of asserting the faith in a new forthcoming kind of literature? Although science may badly affect literature so as to produce an impoverishing mechanization of literary style (Jules Verne, Paris au XXe siècle, 1863), it also gives a valuable opportunity to create more ergonomic formats for a wider distribution and a more easily handheld book. Since the late 19th century until WWII, many futuristic novels propose to consider the book as it is located at the junction of Science and the Humanities rather than in their dichotomous opposition. Regarded as a specific leitmotiv, such a topic of technological and transmedia conversions of the book leads to reconsider the evolution of the identity paradigm of France as a “literary nation”. It also gives the opportunity to investigate the discrepancies and coincidences between the conjectural scope of these futuristic novels and the factual history of technological advances. [less ▲]

Faisant partie intégrante de notre vie quotidienne, l’activité physique et la sédentarité constituent deux notions qui s’opposent dans la conception d’un style de vie sain. Les recherches actuelles montrent que chacune d’elles devrait faire l’objet d’une attention particulière. Toutefois, qu’ils fassent partie du grand public ou appartiennent à des professions liées à la santé, il apparait que les individus ne construisent pas toujours des représentations adéquates à propos des bonnes habitudes de vie. Dans la perspective d’influencer favorablement la culture des citoyens en matière d’activité physique, il s’avère donc nécessaire de rappeler régulièrement les informations clés qui devraient être retenues et appliquées dans la vie de tous les jours. Afin d’illustrer la manière avec laquelle les représentations peuvent constituer le fil rouge d’un processus amenant les gens à adopter un style de vie physiquement actif et peu sédentaire, nous passerons brièvement en revue la définition de l’activité physique, l’identification de ses effets et les recommandations proposées actuellement par les agences de santé publique. Nous utiliserons différentes approches ludiques originales, susceptibles de faire vivre aux participants des expériences visant à stimuler le traitement des informations et à privilégier leur rétention. Au niveau de la définition de l’activité physique, l’objectif consistera à faire ressortir les différentes dimensions de l’activité physique. Puisque les recherches les plus récentes en soulignent l’incidence de plus en plus marquée, nous insisterons également sur la distinction entre les différents niveaux d’intensité de la pratique. Ensuite, une classification des effets bénéfiques de l’activité physique sera proposée avant une révision des recommandations internationales. Les modalités de présentation originales qui seront mises en place stimuleront la prise de conscience de certaines mauvaises représentations, courantes dans le public. La dernière partie de l’exposé consistera à illustrer les contre-arguments à opposer à ceux qui ne sont pas encore convaincus qu’ils pourraient bouger davantage. [less ▲]

Pornographic consumption or exposure to sexually explicit media (SEM) during adolescence raises many questions, in particular concerning its incidence on the level of a teenager's psychosexual development and sexual behaviour. Adolescence is a stage of identity formation, characterized by the adoption of risk taking and exploratory behaviours, of which the consumption of pornography is part. Whereas some studies noticed an impact of the exposure to sexually explicit media on the level of the subject's psychosexual development, attitudes towards sexuality and sexual behaviour, other studies do not highlight any significant links between the voluntary or involuntary exposure to pornography and risk taking sexual behaviours. Two researches will be presented to deal with this question. The first study, relating to a sample of 319 teenagers aged between 15 to 18 (52% boys), shows that 85% of the subjects have already seen pornographic material, the average age a child first views pornography being between 10 and 14. Our results indicate that the forms of exposure to SEM as well as the representations of pornography and the impact of pornographic material on their sexuality are different depending on the subject's gender. Our second study, relating to a sample of 47 juvenile sexual offenders, will make it possible to consider the forms of consumption of these young people and the possible links between their sexual offence and the consumption of pornography.

A la suite des scandales médicaux de Toulouse et d’Epinal, la sécurité des soins en radiothérapie a connu un intérêt croissant. En même temps qu’une réglementation plus exigeante est émise, des méthodes de gestion de risques issues de l’industrie sont expérimentées et les résultats des expériences publiés. Toutefois, ces méthodes sont souvent basées sur des hypothèses à priori sur le comportement humain et aucune n’analyse spécifiquement comment les risques sont évalués par les divers acteurs et groupes d’acteurs intervenant dans le processus de prise en charge du patient. Le présent article fournit les résultats d’une étude empirique analysant les facteurs psychologiques expliquant les différences de perception du risque de mauvaise localisation par les travailleurs d’un service de radiothérapie. Il démontre que les médecins qualifiés d’experts minimisent ce risque en s’appuyant d’une part sur leur connaissance de la fréquence de réalisation du risque et des conséquences pour le patient et d’autre part sur leur expérience et leurs compétences pour le prévenir et le réduire. Le personnel d’administration qualifié de profane ne s’estime pas concerné par ce risque. Bien que beaucoup le considèrent comme élevé, ils n’ont pas d’avis sur les différents facteurs de perception proposés dans le cadre d’analyse de Slovic. [less ▲]

Implementation of blood conservation strategies is a current issue in a public health view, especially in cardiac surgery. A service project has been initiated in the cardiovascular department of the CHU of Liege aiming to develop a blood conservation program. This project has evolved into the creation of a clinical pathway of the cardiac surgery patient and then into an institutional model for the development of other clinical pathways. This evolution leads to meet with the missions and strategic objectives of the Institution and some national projects. The process of this approach weaves a horizontal and vertical grid. The multidisciplinary membership, supported by medical and nursing leadership and the institutional support, will determine the sustainability of this project. [less ▲]

A l’instar d’une entreprise industrielle, l’hôpital actuel présente les caractéristiques suivantes, quel que soit son statut ou sa localisation : Il est constitué d’un ensemble de ressources rares et limitées, de nature humaines, techniques, financières et immatérielles (savoirs et connaissances), dont il doit justifier d’une utilisation efficiente (en clair, maximiser le rapport output/coût) en regard des attentes diverses et parfois contradictoires de ses différentes parties prenantes (patients, collaborateurs, autorités de financement, autorités de contrôle) s’il veut remplir le rôle de création de valeur sociétale naturellement dévolu à toute organisation. En terme managérial, son défi quotidien est de : Gérer de manière coordonnée des flux multiples (flux des patients physiques, objets des soins ; flux des médicaments et des traitements, nécessaires à la fluidité du flux des patients ; flux d’information, traduction virtuelle des patients physiques nécessaire lui aussi à la fluidité du flux des patients) dans un souci permanent d’efficience multiple : garantir le bon soin au bon patient au bon moment avec l’information suffisante, les médicaments et l’infrastructure adéquate, le tout, au moindre coût.

Confronté au problème de surpopulation, conséquence de leur fréquentation sans cesse croissante, les services d’urgence ont mis en place des stratégies opérationnelles basées sur des filières de soins organisées au départ de systèmes de triage des patients. Pareils outils ont démontrés leur intérêt mais s’avèrent aujourd’hui insuffisant, raison pour laquelle de nouvelles stratégies voient le jour. Un d’elle, le triage infirmier avancé, permettant à un infirmier d’initier la démarche diagnostique juste après la catégorisation du patient, semble être une promesse d’avenir. Une étude portant sur un triage infirmier avancé pour les patients se présentant pour une douleur thoracique a été menée récemment au CHU de Liège. Les résultats encourageant de cette étude révèlent un gain de temps dans la prise en charge des patients en faveur de ce nouveau système et une durée totale de séjour aux urgences réduites, principalement en période de surpopulation. Il se confirme donc que le triage infirmier avancé, couplé à un triage classique, particulièrement en période de surpopulation, améliore la prise en charge des patients en terme de temps et réduit le temps total de séjour aux urgences combattant par là la surpopulation.

INTRODUCTION Serve in modern tennis game is an important offensive weapon for players (1-2). In kinematic analysis, serve is the most studied stroke of this game. The aim of our study was to compare the performance of two specific populations: international players versus national players. In particular, racket speed at impact and accuracy of ball were assessed. METHODS A tennis court was reconstructed in a motion analysis laboratory. The position of the racket was evaluated in 3D at a frequency rate of 200 Hz. Tests were performed on 6 professional players (international level) and 9 non-professional players (national level). Each of them served 25 trials in direction of the “T” area of deuce diagonal. Two squares of 1m² and 2 m² respectively were delimited on the corner of the serve square. The instruction for both groups was to serve in the “T” area with the highest ball speed and minimal ball rotation (flat serve). RESULTS Although the forward speed of the racket at impact was identical between the two groups of players (International 36.35 ± 2.37 m/s and national 36.37 ± 2.90 m/s, p-value 0,991), the accuracy and consistency of serves on the target area is better for international players group (1m² area: International 33% ± 7% and national 14% ± 12%, p-value 0.0053; 2m² area (including 1m² area): International 71% ± 8% and national 54% ± 12%, p-value 0.0096; Out of zone: International 29% ± 8% and national 46% ± 12%, p-value 0.014). DISCUSSION High-velocity ball seems to be a key factor for serve performance (3). It is known that there is a relationship between racket speed and ball velocity (4). Both groups have high racket speed. However, international players serve with better accuracy and consistency than national players. We hypothesize that these differences are due to capacity of international players to adapt to a particular environment. Moreover, international players could give priority to consistency over velocity. We conclude that high-velocity serve is not a sufficient criterion to perform at international level; consistency and accuracy are two important factors to reach this level. [less ▲]

Islands are subject to human activities and their impacts on land and marine ecosystems. They are also often isolated from some of the continental influences but on the other hand different kind of human activities can be concentrated in small areas. These characteristics make possible the management of many programs that use whole islands, or some of their parts, as a reference station for environmental studies. From this perspective, the program STARE-CAPMED has begun in 2012 at STARESO, an oceanographic research station established at Calvi Bay (Corsica) since the early 70’s. It aims to create a reference station for the study of emerging local and global anthropogenic impacts on marine pristine ecosystems. Several universities are involved in this project and provide their expertise in various fields of marine sciences. This program provides a precise view of the environmental processes that occur, which are strongly linked with economic and cultural issues. [less ▲]

Citizen science (CS) is a fairly new concept that is rapidly gaining traction in the industrialized democratic world. Although it is often likened to public participation in science, CS takes on many forms and orientations. In this presentation, I link CS developments and practices to the advent of new and emerging technologies (NEST), such as bio- and nanotechnologies. I draw on three Flemish cases of CS linked to NEST to illustrate how CS co-evolves with Flemish and European policy shifts towards responsible innovation governance. The cases serve to highlight how various conceptions of CS enact divergent rationales for public involvement in science and promote competing visions of the volatile relationship between science and society. The clash of CS perspectives within and through NEST produces a highly ambiguous innovation context that is simultaneously characterized by excitement and (pre)caution; public and formal expertise; policy dictates and public dialogue; and deterministic and constructionist views of innovation. How implicated actors (policymakers, scientists, citizens, and other stakeholders) make sense of, and deal with, these ambiguities is one of the key challenges CS faces today. [less ▲]

Quality management frequently appeals to performance indicators (PI) without questioning their constructed and contextual dimension and the reduction of the social complexity they induce. Practices and discourses in this field tend to swing between two antinomic registers: strenghtening of a managerial approach by the authorities and new participatory expectations by stakeholders. Quality-oriented approaches and performance measurement advocates a quantitative practice based on a top-down, standardised approach focused on statistical knowledge and advocating a desire of transparency and increasing efficiency. The indicator-based measurement also endorses a legitimacy and accountability function (Zittoun 2009). Quantification of social phenomenon leads to a double reductionism : PI reduce social complexity to a single figure, and contribute at the same time to a normative twist of public action when pushing forward the search for performance and efficiency as main objective of policies while downplaying other less measurable social or environmental dimensions (Salais, 2010). In the last decade, public governance focused so much on numbers and benchmarking that the digits and indicators seem to structure the whole decision making process instead of being a simple adjuvant to it (Dahler-Larsen 2012, Ogien 2009). Simutaneously, local actors have to translate in local practices the policy indicators that where defined by experts far away from local concerns. This top down approach puts the autonomy of local professionals under pressure (Chauvière 2007). These tensions could be resolved by defining new modes of coordination between experts and the knowledge of stakeholders. Beyond the criticism of “governing by numbers” the hypothesis is to test the emergence of new families of context rich operational indicators, supporting local participation (Didier et al 2013). This paper proposes to analyze these tensions in the case of the development of quality management processes in universities in Belgium and show how the development of quantification mechanisms resisted participatory processes in the definition of indicators and statistical models (Fallon & Leclercq 2013). It will question how can stakeholders be involved in the definitions of measures, contribution to the framing of the convention of what is locally important and what is not. [less ▲]

Une cartographie systématique à grande échelle des sols de Belgique a été conduite entre 1947 et 1991. Les observations étaient effectuées au moyen de sondages à la tarière jusqu’à une profondeur standard de 125 cm dans la mesure du possible, avec une densité moyenne de 2 sondages à l’hectare. Des plans cadastraux au 1/5 000 ont servi à noter les observations et à tracer les limites des plages cartographiques, généralisées par la suite par transcription sur fond de carte topographique au 1/10 000. La carte finale a été publiée par planchettes à l’échelle du 1/20 000, associées à des livrets explicatifs. La carte s’appuie sur une légende originale, basée majoritairement sur des critères morphologiques du sol, aisément identifiables sur le terrain, objectifs (sans a priori d’interprétation) et les plus permanents possibles. La combinaison de ces critères, transcrits en symboles alphanumériques, est à l’origine de la très grande richesse sémantique de la légende, forte de plus de 10 000 unités cartographiques de sols. La numérisation de la Carte des Sols de la Belgique et la structuration de l’information délivrée par la légende ont ouvert de nombreuses perspectives en terme d’applications. Mais au-delà du produit final qu’est la carte, le véritable héritage légué est l’extraordinaire connaissance experte accumulée par les cartographes durant la durée du projet. Si une part inestimable de ce savoir s’en est allée en même temps qu’eux, une part tangible est accessible à travers de nombreuses publications (livrets explicatifs, monographies, thèses, articles) ou parsème divers documents d’archive (notes de terrain, PV de réunion, rapports d’excursions). Ces derniers sont également une invitation à se replonger dans le contexte historique, scientifique et philosophique de l’époque des levés. Ils permettent de ce fait de mieux cerner la manière dont la légende a été pensée, élaborée, adaptée, remaniée. L’éclairage que ces publications et documents d’archive donnent sur la carte et sa légende laisse entrevoir une richesse d’information insoupçonnée. Se la réapproprier par une interprétation avertie de la carte est essentiel préalablement à toute valorisation. Cette communication se propose de justifier l’intérêt de cette démarche au travers de multiples exemples. Ils ont été choisis de manière (i) à présenter la diversité des cas rencontrés et (ii) à illustrer l’impact d’une telle interprétation sur la qualité des produits issus de 2 projets menés actuellement : la corrélation de la légende de la Carte des Sols de la Belgique avec le système de classification international World Reference Base et la contribution belge au projet mondial GlobalSoilMap.

Beaucoup d’enfants suivent des cours d’accoutumance à l’eau et différentes approches existent. Cette étude vise à comparer deux de ces méthodes et d’en vérifier l’efficacité. Nous avons soumis à trois groupes d’enfants une batterie de tests complète. Vingt-cinq enfants bénéficiaient d’une méthode traditionnelle (TRADITION), 25 autres de la méthode CEReKi (CEREKI) et les 27 derniers ne suivaient aucun cours (CONTRÔLE). Tous ont été testés avant et après une période de cinq mois. L’approche pédagogique des deux écoles a été analysée durant 13 séances filmées. On observe une amélioration linéaire du niveau d’accoutumance à l’eau des enfants en fonction de leur âge qu’ils suivent ou non des cours. Les résultats démontrent l’efficacité des deux écoles. Les enfants CEREKI semblent s’améliorer autant mais en moins de séances. Cela peut être dû à un meilleur temps d’engagement moteur. La méthode CEREKI s’avère donc très efficace, même dans une piscine peu adaptée. [less ▲]

This paper presents an original theoretical model combining ideal-types and bundles in order to apprehend a poorly studied phenomenon, the professionalization of human resource management (HRM) in social enterprises. This theoretical model elaborated from a literature review fits into a deductive approach. The first objective of this contribution is to show the added values and limits of such an a priori conceptualization. By replacing that model within the contextualist framework of analysis (Pettigrew, 1987) and by equipping that approach with adapted methodologies, some limits inherent in a deductive approach are avoided. The second goal of this paper is then to demonstrate how such a combination helps to pass over the limits of the theoretical model based on bundles and ideal types. [less ▲]

Ces dernières années, les institutions Européennes ont joué un rôle clé dans la régulation et l’orientation des politiques publiques pour l’emploi des États-membres (Amparo-Serrano et Martin-Martin, 2012). Dans ce cadre, la flexicurité s’est imposée comme une référence des politiques en matière de droit du travail, d’emploi, de sécurité sociale et de formation professionnelle (Conter et Orianne, 2011). En Belgique, cette exigence d’allier flexibilité et sécurité sur le marché du travail a constitué le cœur de nombreux discours et programmes politiques, pour finir par s’estomper progressivement, à la suite de crises financières et économiques l’ayant fortement éprouvé. Ce « concept » a-t-il pour autant effectivement disparu ? À partir d’une étude qualitative basée sur des entretiens semi-directifs menés auprès d’acteurs institutionnels – experts et analystes du marché du travail – nous nous sommes rendu compte que si la sémantique n’est plus, les principes de flexicurité sont, quant à eux, toujours présents dans le discours des individus. De plus, ces principes semblent détenir une portée normative de taille quant à la redéfinition de l’articulation des temporalités sociales : d’une sécurité de l’emploi, nous serions en train d’effectuer un glissement vers une sécurité en emploi de l’individu. La rhétorique n’est pas innocente : désormais, ce n’est plus tant l’individu qu’il s’agit de protéger (droit du travail, etc.) mais bien les transitions – multiples et sinueuses – opérées par ce dernier. Pour y parvenir, l’État le responsabilise : il doit désormais être capable de se prendre en mains : « c’est le passage d’un ‘État qui protège’ à un ‘État qui rend capable’ » (Vrancken, 2008).

The Van der Pol (VdP) oscillator is a paradigmatic model for description of self-excited oscillations, which are of practical interest in many engineering applications. In this paper the dynamics of a VdP-Duffing (VdPD) oscillator with an attached nonlinear tuned vibration absorber (NLTVA) is considered; the NLTVA has both linear and nonlinear restoring force terms. In the first part of this work, the stability of the trivial solution of the system is investigated, following results of previous works. The analysis allows to define an optimal tuning rule for the linear parameters of the absorber, which substantially enlarges the domain of safe operation of the primary system. In this case, the system loses stability through a double Hopf bifurcation. In the second part of this work, the bifurcations occurring at the loss of stability are analytically investigated, using the technique of the center manifold reduction and transformation to normal form. The obtained results show the effects of the nonlinear parameter of the absorber, which, in turn, allows to define its optimal value in order to avoid subcriticality and reduce the amplitude of self-excited oscillations.

In the framework of self-regulated learning theories, the DELV (“Understanding one’s own learning”) is a 165-page metacognitive intervention program developed by Büchel & Büchel (1995, 1997, 2009, 2010, 2011). It includes 8 types of decontextualized exercises which notably allow to develop the learner’s metacognitive knowledge and skills (for more details, see Büchel, 2013b). They also make it possible to work on cognitive and psycho-affective aspects. Transfer can thus be better developed. This tool has been used since its first version (Büchel & Büchel, 1995) both at the Atelier d’Apprentissage of the University of Genève (Unige, Switzerland) and at that of the University of Liège (ULg, Belgium) since their creation (respectively in 1996 and in 2009), (for more details, see Büchel, 2013a; Frenkel, in press (b)). Our main purpose is to present how we can use this tool individually in order to enable the student to activate his/her “sleeping potential” (for more details, see Frenkel, in press (a)). By focusing on adolescence, we will present (a) our theoretical background (conception of learning and intellectual functioning, criteria and levels of mediation), (b) the variables worked on, and (c) the results obtained.

A few years ago, asteroid polarimetry allowed to discover a class of asteroids exhibiting peculiar phase polarization curves, collectively called "Barbarians" (a dozen are known) from the prototype of this class, the asteroid (234) Barbara. All such objects belong to the taxonomic classes L, Ld, and K, all related to the general S-complex. However, the "Barbarian" polarimetric properties are not found among all known L-class asteroids. Therefore, we cannot be sure that composition is the only and one responsible of the wide negative polarization branch. On the other hand, it was also suggested that a peculiar distribution of incidence/diffusion angles, resulting from the presence of large concavities on the object surface, could play a role in the polarimetric behaviour. Based on such motivations, we are running a systematic campaign for shape determination at the C2PU telescope of the Observatoire de la Côte d'Azur (Calern site) and several other sites in the world. By using photometric inversion techniques we hope to obtain indications on the presence of concavities. [less ▲]

The efficiency of spray application of foliar plant protection products with hydraulic nozzles on vertically oriented and hydrophobic plants at early growth stages can be very low. The spray retention by crop leaves is affected by application parameters resulting from nozzle kind, size and operating pressure as well as spray mixture physicochemical properties. When optimizing the spray application, such targets are often used to perform retention trials for comparative purpose, i.e. indoor grown monocotyledonous at two leaves stage. A typical arrangement consists in spraying few plants sufficiently spaced underneath the nozzle to avoid interference due to secondary droplets from impacts on other plants. However, retention trials turn out to ineffective for significantly discriminating between application methods and mixtures due to the high variability between trials resulting from the different droplets retained by each plant. An alternative to retention trials is to tackle spray retention with a physical approach at the droplet scale. Such tests are often performed using high speed imaging with high magnification optics to characterize droplet impacts; adhesion, rebound or shatter on small excised leaf areas and neglect, however, the overall plant architecture. The aim of this paper is to evaluate a droplet interception model connecting actual spray retention with process-driven retention models. In this study, barley plants (BBCH11) were sprayed with 2 formulations using the same nozzle. The actual spray retention was assessed by dosing a fluorescent tracer added to the sprayed mixture. The plants were placed linearly below the center of a single moving nozzle during sprayings. Each plant was reconstructed in 3D afterwards using a structured light 3D scanner and used as input for the model. A virtual nozzle was built on the base of droplet size distributions measured with high speed shadow imaging by performing an adjustment of the distribution by the method of moments. A ran-dom droplet distribution was allocated for each spraying of a barley plant. Droplet velocities were given to droplets on the basis of the droplet velocity – diameter correlation by resolving the droplet transport equations for different droplet sizes. Initial droplet positions were ran-domly given. The interception model is based on a mathematical formalism for the intercep-tion between triangles of the 3D plant and droplet directions. If the droplet impacts a leaf, the amount actually retained by the leaf was computed on the basis of the droplet impact energy and impact behavior from experiments with high speed shadow imaging. In conclusion, the interception model allowed determining the spray retention by plants and discriminating ap-plication parameters by explaining the variability resulting from various droplet size distribu-tions intercepted by single plant.

Solving spatial inverse problems in the Earth Sciences remains a considerable challenge given the large number of parameters to invert for, the non-linearity of forward models and as a result the ill-posedness of the problem. Geostatistics is therefore needed to specify prior models, more particularly, information to control the spatial features of the inverse solutions. We used multiple-point statistics (MPS) to build models of pre-defined hydrofacies: clay, sand and gravel facies constrained to geological data (hard data) and geophysical data (soft data). The electrical resistivity tomography method was chosen to bring relevant spatially distributed information on the presence of the facies, given its sensitivity to variations in lithology and porosity. The comparison of the geophysical signature of the deposits with direct observations in boreholes enables to derive the conditional probability of observing a facies given its electrical resistivity. This is used to produce probability maps for each facies and constrain stochastic simulations of the alluvial aquifer. Then, the probability perturbation method (PPM) is used to integrate hydraulic heads data, using MPS to generate models. This process enables us to obtain calibrated models of the aquifer. The PPM algorithm will automatically seek solutions fitting both hydrogeological data and training-image based geostatistical constraints. Only geometrical features of the model are affected by the perturbation, i.e. we do not attempt to directly find the optimal value of hydrogeological parameters (chosen a priori), but the optimal spatial distribution of facies whose prior distribution is quantified in a training image. The methodology is first tested with a synthetic benchmark. The tests performed show that the choice of the training image is a major source of uncertainty. Therefore, one first needs to select those training images consistent with the geophysical data (and hence reject the inconsistent ones). Then, we proceed with them to hydrogeological inversions. Geophysical data (soft constraints) acts as an accelerator of convergence by reducing prior uncertainty. The hydraulic conductivity of each facies is a sensitive parameter, but it can be easily optimized prior to the PPM process. The stochastic method is then successfully applied within the context of an alluvial aquifer submitted to a pumping experiment. We show how the integration of various sources of data (borehole logs, geophysics, hydraulic heads) aids in calibrating hydrogeological models, locating high hydraulic conductivity zones and reducing uncertainty. The developed methodology proposes a common framework (multiple-point statistics) to integrate various information sources with variable resolutions relevant for hydrogeology: geological, geophysical and hydrogeological data. The method can be extended to integrate tracer tests to enable the calibration of transport parameters as well. The originality of the method is to use geophysical data both to refine the choice of the training image and to constrain the inversion of hydrogeological models. [less ▲]

School achievement plays an essential role in terms of professional and social adaptation. However, all the students do not always perform as the system requires them to. In Belgium, at the end of compulsory education, one student out of two lags behind in their school education (Indicators from the Fédération Wallonie-Bruxelles [Walloon-Brussels Federation], 2012). In this context, we do not consider that there are “bad” learners. Instead, there are those students whose learning profile is more or less in line with the context’s requirements and those whose profile is not. In many works, the student’s learning profile is operationalised by measures on 3 levels: cognitive, metacognitive and psycho-affective. These psychological variables, which are major components of self-regulated learning, play a central role in the explanation of school performance (for more details, see Frenkel, in press; Frenkel & Deforge, in press). This profile is not fixed once and for all. It evolves over time and it represents the result of the interaction between these three variables with other factors, notably bio-medical, socio-demographical ones, factors related to family environment (Pourtois, Desmet & Lahaye, 2004; Trudel, Puentes-Neuman & Ntebutse, 2002) and the too often forgotten factors linked to class management and social interactions between students and teachers (see Wang, Haertel & Walberg, 1994). Determining the students’ learning profile enables us to identify their strengths and work on their weaknesses. Therefore, it is essential that psycho-educational teams have validated tools at their disposal in order to carry out this task. Our aim is to propose new tools which will complement the already-existing ones. In this presentation we propose to introduce and discuss our methodology and the results obtained. The starting target population was made up of 198 primary school students divided equitably into three levels (second year of primary school, fourth year of primary school and sixth year of primary school). A problem-solving task based on the DELF (Büchel & Büchel, 1995) was created. It was completed by two questionnaires to fill in before and after the task. The learning profile defined on this basis was analysed according to several variables (age, gender, socio-professional category, school results). Group testing is still in progress. We will also illustrate our presentation with the first results of individual testing which will begin in May 2014. References - Büchel, F.P. & Büchel, P. (1995).

BUCHAREST-PRINCETON SEMINAR IN EARLY MODERN PHILOSOPHY 14th Edition Organized by the Research Centre for the Foundations of Modern Thought (FME), University of Bucharest, in collaboration with the Philosophy Department at Princeton University 8 – 13 July 2014 Bran, Romania De rerum natura: Naturalism, Super-naturalism, Unnaturalism Invited speakers include: Daniel Garber (Princeton University), Roger Ariew (University of South Florida), Igor Agostini (Università del Salento), Peter Anstey (University of Sydney), Olivier Dubouclez (Université de Liège), Tamás Pavlovits (University of Szeged), Jennifer Rampling (Princeton) Description : https://ci3.googleusercontent.com/proxy/8CBWEZYl_gju-O0mEKjDNw0Eh_qIbYUu1oZBKfZqOypmLO1gU9NfBBUnKK5HrwoN-VKG8iQn_PvQpZDlbxq0IwVL9dQOy_HcGJ0=s0-d-e1-ft#https://mail.google.com/mail/u/0/images/cleardot.gif Some Seventeenth Century authors gave a new definition of nature, clearly articulated in terms of natural laws and of their dependence on God. Even if some elder tensions, coming from the Stoic and Epicurean heritage, were thus released, new challenges appeared, related to the limits of nature (is the world finite or infinite?), the structure of matter, the status of the mind and the status of the human being with respect to nature. While some philosophers as Bruno, Telesio and Cardano tried to reach a compromise with Renaissance vitalism, promoting a natural magic and a new alchemy, some others, such Bacon, Descartes, Spinoza, Leibniz, proposed radical different paths. Not losing sight of the manner in which ancient thought (Pliny and Lucretius seem to be naturally summoned) informed modern debate over nature, the seminar will try to uncover a period in which Spinoza could articulate his critique of Descartes as holding a view of man as "imperium in imperio". The Bucharest-Princeton Seminar in Early Modern Philosophy is an international annual meeting of scholars interested in various aspects of early modern thought. The aim of the seminar is to create a stimulating environment for discussing papers and ideas. It includes workshops in the morning and presentations of papers in the afternoon, where participants can present work in progress. While the morning sessions will focus on the theme of “De rerum natura: Naturalism, Super-naturalism, Unnaturalism,” the afternoon sessions seek to give participants an opportunity to discuss their own special interests with an open and sympathetic audience of students and scholars with broad interests in early modern thought. Throughout we try to maintain a balance between the high scholarly level and the informal friendly spirit of a colloquium. The Seminar will take place in Bran, a small mountain resort near Brasov, in Transylvania. It will be hosted in a small, friendly Bed and Breakfast (single or double rooms). The participation fee is 150 EUR for faculty and 90 EUR for students (covering accommodation with breakfast). We invite applications for contributions (from researchers) and for attendance (from students). If you want to contribute a paper, please send a CV and a one-page abstract, and if you want to attend, a CV and a letter of intent – by April 20 – to Vlad Alexandrescu (valexandrescu@gmail.com), Dana Jalobeanu (dana.jalobeanu@celfis.ro).

Super-Earths transiting nearby bright stars are key objects that simultaneously allow for accurate measurements of both their mass and radius, providing essential constraints on their internal composition. We present here the confirmation, based on Spitzer transit observations, that the super-Earth HD 97658 b transits its host star. HD 97658 is a low-mass ($M_*=0.77\pm0.05\,M_{\odot}$) K1 dwarf, as determined from the Hipparcos parallax and stellar evolution modeling. To constrain the planet parameters, we carry out Bayesian global analyses of Keck-HIRES radial velocities, and MOST and Spitzer photometry. HD 97658 b is a massive ($M_P=7.55^{+0.83}_{-0.79} M_{\oplus}$) and large ($R_{P} = 2.247^{+0.098}_{-0.095} R_{\oplus}$ at 4.5 $\mu$m) super-Earth. We investigate the possible internal compositions for HD 97658 b. Our results indicate a large rocky component, by at least 60% by mass, and very little H-He components, at most 2% by mass. We also discuss how future asteroseismic observations can improve the knowledge of the HD 97658 system, in particular by constraining its age. Orbiting a bright host star, HD 97658 b will be a key target for coming space missions TESS, CHEOPS, PLATO, and also JWST, to characterize thoroughly its structure and atmosphere. [less ▲]

Aujourd’hui, l’évaluation de la satisfaction en santé est reconnue comme une mesure qui évalue la qualité des soins. Le premier objectif de ce travail est de connaître le degré de satisfaction des patientes vis-à-vis du suivi postnatal par les sages-femmes de la maternité ND des Bruyères du CHU de Liège. Le deuxième objectif est de mettre en avant les points positifs ainsi que les points à améliorer pour la préparation du retour précoce à domicile après l’accouchement. Des questionnaires de satisfaction ont été distribués aux accouchées. Le taux de satisfaction global du séjour à la maternité est de 77,7% et peut donc être considéré comme très satisfaisant. Durant la période postnatale pour le retour précoce à domicile, il y a 82,6% des patientes qui pensent que les sages-femmes ont répondu à leurs attentes. La comparaison entre les deux groupes de patientes suivant le type de retour au domicile, précoce ou normal, on ne relève aucune différence significative. Cette étude a permis de connaître les attentes prioritaires des accouchées de la maternité. Des améliorations devraient être apportées principalement à la disponibilité du personnel, à la clarté des explications et à la qualité de l’information. [less ▲]
