Les indicateurs de santé mentale existants restent partiels en Europe, et le système de surveillance sanitaire du Luxembourg ne semble pas y avoir échappé. Cette carence d’informations fiables bien connue est liée en partie aux difficultés méthodologiques inhérentes aux recueils de ces données et à la complexité des classifications. Par ailleurs, aucune information sur les besoins locaux des professionnels de première ligne n’existe. Avec l’appui du RE.SO.NORD (REseau du centre SOcial de la région du NORD), une équipe de l’unité de recherche INSIDE a mis en oeuvre d’un projet innovant, intitulé « diagnostic des professionnels sur les besoins associés à la santé mentale ». Ce diagnostic a eu pour objectifs d’identifier les problèmes de souffrance psychique et sociale des clients des communes rurales, décrits par les professionnels sociaux et de santé de première ligne et de déterminer leurs besoins pour maintenir/améliorer la qualité de leur travail au quotidien et l’efficacité des prises en charge. Cette approche s’inscrit dans une compréhension des processus présents dans la construction et l’amplification des souffrances mentales (angoisses permanentes, dépressions, etc.) ainsi que l’accumulation de facteurs psychosociaux (exigences du monde du travail, ruptures familiales, etc.) qui contribuent à leur émergence. Vingt-huit professionnels (médecins, assistants sociaux, psychologues) travaillant auprès d’adultes de 18 à 65 ans ont été interrogés. L’analyse des transcriptions de leurs discours met en évidence la nécessiter d’insister sur :1) la mise en place de démarches globales, et sur le fait d’associer les aidants aux échanges sur la connaissance de la maladie et de ses symptômes (lieux de parole, etc.) ; 2) la nécessité de faciliter et d’encourager la consultation médicale ou psychologique ; 3) l’engagement et le développement d’une responsabilisation clients-aidants. Les professionnels proposent également que l’on augmente : 1) les possibilités de rencontres entre les médecins, assistants sociaux, psychologues (synthèses, analyses de cas, etc.) qui permettraient à la communication d’être plus efficiente ; 2) la mutualisation des informations entre les professionnels de proximité en créant une plate-forme d’échanges interactifs qui faciliteraient le suivi des parcours ; 3) les formations interdisciplinaires pour actualiser les connaissances (dépression, suicides, etc.), renforcer le respect réciproque clients-aidants-professionnels et la déstigmatisation. ____________________________________ Mental Health & Recovery Luxembourg 23 & 24 Octobre 2014 2 Needs of local social and health professionals addressing the mental health problems of rural communities in the North. The existing mental health indicators remain partially developed in Europe, and Luxembourg’s system of health surveillance does not seem to have escaped. This lack of reliable information is well known partly due to the methodological difficulties inherent to the collections of data and complexity of the classifications. Moreover, any information on the needs of local frontline professionals exists. With the support of RE.SO.NORD (REseau du centre SOcial de la région du NORD), a research unit INSIDE team has implemented an innovative project " diagnostic des professionnels sur les besoins associés à la santé mentale ». The aim of this diagnostic was to identify problems of psychic and social suffering of clients in rural towns, described by the social and health frontline professionals, and to define their needs to maintain / improve the quality of their daily work and effectiveness of their care. This approach is part of an understanding of the processes occurring in the construction and amplification of mental suffering (permanent anxiety, depression, etc.) and the accumulation of psychosocial factors (demands of the workforce, family separation, etc.) that contribute to their emergence. Twenty-eight professionals (doctors, social workers, psychologists) working with adults 18 to 65 years were interviewed. The analysis of transcripts highlighted the need to focus on: 1) the development of comprehensive approaches, associating caregivers to exchange knowledge of the disease and its symptoms (place of dialogue, etc.); 2) the need to facilitate and encourage medical or psychological counseling; 3) commitment and a growing accountability of clients -caregivers. The professionals also propose to increase: 1) the possibilities of meetings between the doctors, social workers and psychologists (syntheses, case studies, etc.) allowing communication to be more efficient; 2) the sharing of information between local professionals by creating a platform for interactive exchanges which would facilitate the follow-up of the trajectory ; 3) interdisciplinary training to update knowledge (on depression, suicide, etc.), enhancing mutual client-family caregivers-professional respect and destigmatization. ____________________________________ [less ▲]

En littérature ou dans le « 9ème art », le danger – qui est un ressort dramatique et un pourvoyeur de suspense – n’a de pertinence que s’il est éprouvé par le lecteur. Comment l’auteur de roman ou de BD procède-t-il pour créer cette émotion chez celui-ci ? En nous appuyant sur une approche cognitive et pragmatique, nous analyserons l’incipit de Vipère au poing (Hervé Bazin, 1948) et l’une des aventures de Blake et Mortimer, La marque jaune (Edgar P. Jacobs, 1956), afin de décrypter les procédés mis en œuvre pour que le lecteur s’imagine courir lui-même un danger, au même titre que les héros auxquels il s’identifie. [less ▲]

The objective of this study is to develop a simulation technique that enables to describe the interactions between snow and a moving surface. The develop- ments of this study are focused on the application of the interactions between a tire tread and a snow-covered road.Contrary to a continuum mechanics approach snow is considered to exist of discrete grains which are allowed to bond and collide with each other. There- fore, a discrete approach based on the extended Discrete Element Method is applied to the snow. Micro-mechanical models are developed to describe the deformational behaviour of snow. The micro-mechanical models describe the deformation and growth of the bonds between grains as well as the contact behaviour of snow grains on the grain-scale. Further, the age of a snow sample, the temperature and deformation rate applied are taken into account by the de- veloped models. The deformational behaviour of snow under brittle and ductile loading rates is validated with experimental data of common measurements in the field of snow mechanics. The simulation results successfully recapture the macro- and micro-scale deformation behaviour of snow and enable to identify the primary deformation mechanism in charge at the different loading rates, densities and temperatures.However, this approach allows treating individual snow grains during loading due to a rolling tire and predicting both position and orientation of grains. The micro-mechanical response of each snow grain in contact with the structure of the tire surface generates a global impact that defines the interaction forces be- tween the snow and the tire surface, which simultaneously indicate the strength of traction. In order to predict the elastic deformation of the tire surface the Finite Element Method is employed.A coupling method is developed between the discrete approach to characterize snow and the finite element description of the tire tread. The coupling method compensates quite naturally the shortages of both numerical methods. Further, a fast contact detection algorithm has been developed to spare valuable com- putation time. The coupling approach was successfully tested and validated with a small scale application but also with the large scale application of tire - soil interaction. The large-scale simulation results of tire – soil interactions showed to be accurate in comparison to similar traction measurements. The results show the ability of the simulation technique to describe the targeted interactions and give valuable insight into the underlying mechanisms. [less ▲]

Towards rationalised computational expense for simulating fracture over multiple scales The project focuses on the numerical simulation of the failure of complex, heterogeneous structures. The simulation of such physical phenomena is of particular interest to practitioners as it enables to limit the number of destructive tests required to design and assess structures, and, ultimately, to decrease the safety factors used in design. In such heterogeneous media, the description of crack or damage initiation and propagation must be done at the scale of the inhomogeneities (e.g. aggregates in a concrete structure) in order for the results to be predictive. If one uses such a fine-scale material model to simulate structures at an engineering scale (e.g. an aircraft composite panel or a concrete beam), very large numerical problems need to be solved. In addition, there is a strong need for engineers to run their models numerous times, for different sets of the design parameters (e.g. loading conditions, geometry or material properties). Tackling such parametric multiscale problems is prohibitively expensive when using brute force parallel computing. However, one can use the fact that solutions to parametric problems usually evolve in a relatively coarse space: solutions to nearby parameter sets are usually close in a certain sense. This idea is classically used in Model Order Reduction, which proposes to reduce the size of the initial problem by several order of magnitude by simply reusing the information generated when solving the initial problem for several different sets of parameters. However, in the case of fracture, the information provided by the initial problem is most of the time insufficient to describe the behaviour of the system for arbitrary parameters. Crack paths, defects, and subsequent ultimate strengths are strongly influenced by an even slight variation in the parameter set. Fortunately, we showed in our previous research that this characteristic only affects a local region surrounding the structural defects, whilst the behaviour far from these regions is remains relatively unchanged for a wide range of parameter values. The proposed project will make use of this observation in a generic way, by coupling Reduced Order Modeling and Domain Decomposition. The structure will be divided in smaller subcomponents, on which Reduced Order Modeling will be applied separately. The consequence will be that the computational efforts will be greatly decreased in the regions that are far away from the damaged zone. Within the process zone itself, the substructuring framework will allow us to automatically switch to classical direct solvers. In this sense, the research aims at rationalising the computational costs associated to the simulation of parametrised multiscale fracture simulations, by concentrating the numerical effort where it is most required and with minimal intervention of the user.

We present recent results aiming at affording faster and error-controlled simulations of multi scale phenomena including fracture of heterogeneous materials and cutting of biological tissue. In a second part, we describe methodologies to isolate the user from the burden of mesh generation and regeneration as moving boundaries evolve. Results include advances in implicit boundary finite elements, (enriched) isogeometric boundary elements and extended finite element methods for multi-crack propagation. ABOUT THE PRESENTER In 1999, Stéphane Bordas joined a joint graduate programme of the French Institute of Technology (Ecole Spéciale des Travaux Publics) and the American Northwestern University. In 2003, he graduated in Theoretical and Applied Mechanics with a PhD from Northwestern University. Between 2003 and 2006, he was at the Laboratory of Structural and Continuum Mechanics at the Swiss Federal Institute of Technology in Lausanne, Switzerland. In 2006, he became permanent lecturer at Glasgow University’s Civil Engineering Department. Stéphane joined the Computational Mechanics team at Cardiff University in September 2009, as a Professor in Computational Mechanics and directed the institute of Mechanics and Advanced Materials from October 2010 to November 2013. He is the Editor of the book series “Advances in Applied Mechanics” since July 2013. In November 2013, he joined the University of Luxembourg as a Professor in Computational Mechanics. The main axes of his research team include (1) free boundary problems and problems involving complex geometries, in particular moving boundaries and (2) ‘a posteriori’ discretisation and model error control, rationalisation of the computational expense. Stéphane’s keen interest is to actively participate in innovation, technological transfer as well as software tool generation. This has been done through a number of joint ventures with various industrial partners (Bosch GmbH, Cenaero, inuTech GmbH, Siemens-LMS, Soitec SA) and the release of open-source software. In 2012, Stéphane was awarded an ERC Starting Independent Research Grant (RealTcut), to address the need for surgical simulators with a computational mechanics angle with a focus on the multi-scale simulation of cutting of heterogeneous materials in real-time.

The idea of universality in international law has faced many challenges, both in theory and in practice. Among them, the theoretical construction of ‘rogue’ and ‘failed’ states has been identified as a challenge to the classic notion of universality, which refers to international law’s universal applicability. However, the issue of how the discourse on failed, collapsed, outlaw, rogue or pariah states questions specifically the principle of universality has not yet been clarified. The analysis through the lens of international law is particularly relevant at a time when the current turn of events in some states poses both theoretical and practical challenges in terms of humanitarian assistance, flows of refugees and economic stability around the world. This article addresses this issue, first by outlining the main elements of the concept of failed and rogue states and of semantically relevant terms. It, then, proceeds to inquire how the discourse about these states challenges the principle of universality along with the traditional state-centric view of international law. In so doing, it attempts to illustrate specific aspects of the principle of universality in international law which are challenged by such theoretical constructions which are based on the premise that fundamental principles enshrined in the UN Charter should only be respected when a state is first a secure (liberal, democratic) place to live in. In this respect, the question of cosmopolitanism in international law comes into play and the article concludes by examining whether the theory of failed or rogue states is a representative expression of global cosmopolitan law.

Le thème de la souffrance occupe une place prépondérante dans les approches socio-écologiques, et biopsychosociales actuelles, les réflexions éthiques sur la qualité de vie et le bien-être et sur la recherche du bonheur. Qu’il s’agisse de la fatigue professionnelle ou la fatigue d’être soi, la problématique des souffrances est au cœur des discours et des rapports sociaux. De même, elle est au centre des interventions qui tentent d’y faire face de façon individuelle ou communautaire dans les soins de santé, les soutiens psychologiques, les actions sociales, etc. Le but de cette session qui s’appuyera sur des travaux de recherches empririques, n’est pas de se demander « y a-t-il plus ou moins de souffrance ? », mais plutôt de s’interroger sur l’émergence des souffrances, elles-mêmes produits sociaux, l’identification des facteurs impliqués et la compréhension des processus en jeu. La souffrance est la résultante d’une conduite, elle-même sociale, dont les valeurs culturelles la rendent plus ou moins supportables. Issue d’une vision que l’individu a sur sa propre existence, les déterminants culturels qui contribuent à développer ces souffrances, à les cumuler, les amplifier, les maintenir de génération en génération seront des objectifs auxquels nous chercherons à répondre. Décomposer ces souffrances et comprendre les liens qu’elles peuvent avoir avec une douleur physique, une privation affective, une carence éducative, pourront être des pistes de discussion. Enfin, face aux mobilités, aux multiplicités, nous tenterons de répondre à la question de la souffrance liée au fait de vivre ensemble dans un contexte démographique, économique et politique changeant.

At the beginning of the 20th century, music schools in Luxembourg founded with the focal objective to form young musicians for amateur orchestras and choirs. Given that this was quiet a challenging goal, reality proved that it was difficult to assume. In 1998, after many years of discussion, the parliament of Luxembourg finally voted a law of music education. The aim was to offer an equal level of music education in every region of the country and to motivate more children to attend music courses. Politics facilitated unconsciously, but surely not unwillingly a renaissance of amateur music. But these obvious advantages were lessened by some serious problems. An important part of the students gave up and were disgusted by music practice. In my paper I will describe, how the artistic performance level in amateur ensembles increased, but did not lead to more musicians. But this was not only due to music education, but also to new facilities in practicing music. I will describe, by presenting the statistics of the last few years, that the Luxembourgian system of music education has become elitist in the sense of being well adopted for talented students, but that it does not suit at all for average pupils, who want to make music just for leisure. Only a minor part of young people attend music schools, with an important number beginning musical training at the age of eight years or even earlier, but with a decreasing number completing their musical instruction. Nevertheless, general music education is offered for everybody in primary and secondary schools, i.e. one obligatory hour per week for every pupil from six to fourteen years. However, few students older than fourteen make use of a more specialised offer of music education in secondary schools. Most of the future music students, the elite, opt for this possibility. Music education in Luxembourg is based on the francophone system of solfège, a method for future singers and professional musicians. It is also partially transferred to some instrumental disciplines. However, during the last two decades, in these countries – France and Belgium – solfège is replaced by a less rigorous and better-adapted method of musical training. My paper will also give an historical insight into the system of “solfège” and its didactics over the centuries. [less ▲]

In this seminar we consider the problem of constructing a numerical method particularly well suited to modelling domains described by segmented image data of the human body. Instead of constructing a conforming mesh of the problem domain, we use implicitly defined domains described using the level-set method. We then include information about the implicitly defined domains by enriching the usual finite element basis functions defined on a cartesian quadtree or octree mesh with hanging nodes. This approach introduces significant complexities compared with classical finite element methods. We will discuss difficulties with the treatment of hanging nodes, numerical integration and imposing Dirichlet boundary conditions. We will discuss the possible future of extensions of this work, including cutting of soft tissue, multiscale problems with complex microstructure, and model order reduction problems. [less ▲]

New tools for editing of digital images, music and films have opened up new possibilities to enable wider circles of society to engage in ’artistic’ activities of different qualities. User generated content (UGC), a term that already transmits a notion of amateur artists, has produced a plethora of new forms of artistic expression. One type of UGC are mashups, which are compositions that combine existing works (often) protected by copyright, and transform them into new original creations. The European legislative framework has not yet reacted to the copyright problems provoked by mashups. Whereas the flexible US fair use doctrine has accommodated mashups rather easily, the strict corset of limitations and exceptions in Art 5 (2)-(3) of the InfoSoc Directive does not leave any, or only very lit-­‐ tle, room for this innovative and widely popular form of artistic expression for commercial or non-­commercial purposes. The paper analyzes the current Euro pean legal framework and identifies its insufficiencies with regard to enabling a legal mashup culture. By comparison with the US approach, an attempt is made to suggest solutions for the European legislator, based on the policy proposals of the EU Commission’s “Digital Agenda” and more recent policy documents (e.g. “On Content in the Digital Market”, “Licenses for Europe”). In this context a distinction is made between noncommercial mashup artists and the emerging commercial mashup scene. [less ▲]

Cette intervention est consacrée à l’analyse et à la mise en perspective d’un fait divers criminel que nous avons découvert fortuitement, au cours de nos recherches menées sur les transformations de la vallée du Doubs dans la seconde moitié du XIXe siècle, dans le cadre de notre programme de recherche « malaise dans la ville ». En quelques mots, voici les faits : en 1875, un paysan relativement aisé et sa maîtresse, une Bohémienne Sinti, Bellissante Brenet, marchande ambulante, assassinent le mari (Hippolyte Besançon, un chiffonnier) de cette dernière et se débarrassent du corps dans le canal du Rhône-au-Rhin. Le meurtre a lieu à Blussans, village de la vallée du Doubs, situé en aval de Montbéliard. L’affaire s’inscrit dans un contexte particulier, qui est celui de l’industrialisation rapide de L’Isle-sur-le-Doubs. En cette seconde moitié du XIXe siècle, des populations nouvelles affluent dans les bourgs agricoles. Pour beaucoup d’habitants « historiques », il s’agit d’une situation difficile à accepter, ressentie comme une intrusion ; pour nombre d’arrivants, c’est un déracinement, dont les conséquences sont diverses et quelquefois dramatiques. Beaucoup de départements « industriels », notamment ceux de la périphérie métropolitaine, accueillent une forte proportion d’habitants nés hors du département. Ce fait divers est emblématique, à la fois de l’impossibilité de certains nouveaux arrivants à trouver leur place dans les villages en plein changement, de la stigmatisation de certains groupes – les nomades, permanents ou saisonniers –, ainsi que du rôle des nouvelles voies de communication. Ces événements mettent donc en lumière les antagonismes existant entre les membres d’une société villageoise sédentaire et relativement fermée, quoiqu’en voie de déstabilisation, et deux membres d’une communauté de Tsiganes, pour reprendre une dénomination de l’époque.

L’anthropologue Marc Augé a laissé une empreinte si forte dans la manière d’appréhender l’espace en distinguant deux catégories, à savoir le lieu et le non-lieu, que durant les deux dernières décennies, il est devenu presque mécanique d’appeler « non-lieu » tout ce qui relève des espaces créés par la modernité : hypermarchés, bretelles d’autoroute, abords des voies périphériques, parkings, zones industrielles, etc. Il faut certes concéder qu’Augé n’a jamais radicalisé la dichotomie « lieu/non-lieu » qu’il avait lui-même créée. Selon lui, aucune de ces deux catégories n’existe sous une forme pure : « Le lieu et le non-lieu sont des polarités fuyantes : le premier n’est jamais complètement effacé et le second ne s’accomplit jamais totalement. » (Augé 1992, p. 101) C’est, me semble-t-il, une manière d’éluder les problèmes que pose une partition stricte entre ces deux catégories, et surtout une façon d’évincer la présence de l’individu et de ses émotions comme sources d’une appropriation subjective de l’espace.

The article begins with a concise presentation of the legal rules on the participation and use of children in armed conflicts under IHL, IHRL and ICL, focusing on certain definitional challenges. In so doing, the analysis engages with a critical evaluation of the first judgment of the International Criminal Court in Prosecutor v. Thomas Lubanga Dyilo (henceforth Lubanga), being also the first judgment of an international criminal tribunal convicting a defendant solely on the charge of child recruitment. The article examines whether expanding the scope of children’s active participation in hostilities may result into narrowing their protection under IHL by opening the spectrum of children labeled as combatants and lawful targets. Moreover, as new terms appear in policy documents, the article questions their legal validity and status. Finally, it concludes with a comprehensive approach of the status of the relevant legal provisions in Greece. [less ▲]

On présentera un travail en commun avec Sara Arias-de-Reyna, Luis Dieulefait et Sug Woo Shin où nous réalisons, pour tout n pair et tout d, le groupe PGSp_n(F_{p^d}) ou PSp_n(F_{p^d}) comme groupe de Galois sur les nombres rationnels, pour p dans un ensemble de densité positive. La démonstration est basée sur des systèmes compatibles de représentations galoisiennes ayant des propriétés locales spéciales. Au début de l'exposé on esquissera la stratégie; elle est basée sur un travail en commun avec Dieulefait dans le cas de la dimension 2. On expliquera ensuite l'existence d'un corps global et minimal tel que presque toute représentation résiduelle d'un système compatible peut être définie projectivement sur le corps résiduel. En plus, on énoncera une classification simple des représentations symplectiques contenant une transvection dans leur image. Finalement, on expliquera l'existence du système compatible désiré et comment utiliser des techniques de minoration du niveau pour obtenir notre application au problème de Galois inverse. [less ▲]

Automatic Testing of Installed Software is a testing framework to validate the various flavors of software installed on an HPC site. It is composed of a set of unit tests, a runtime and a result-gathering dashboard. These tests are user-oriented as they assess the basic features that a general user expect to work on an HPC platform. Currently, it only focuses on generic MPI functionality as it is one complex and critical component of an HPC platform, but it will be extended to compilers, libraries and performance validation and regression in the future. HPC centers tend to provide a wide choice a software. Different users requires different software, but also different versions of the same software. Combined with the different compilers, MPI stacks, library dependencies, there is an explosion of software flavors installed on an HPC site. Tools already exist to help managing this large variety of software. Users can choose their software through the software list using the 'module' system. Administrators can perform automatic compilation and installation of software using EasyBuild. Additionally, software also require some customizations on some HPC sites. Thus, software flavors need to be validated after installation to check they're working as expected by the users. We developed and provide a set of unit tests together with a runtime and result-gathering framework to perform a such Automatic Testing of Installed Software. These tests take the side of the users in order to test any basic feature that a general user expect to work on an HPC platform. So far, the proposed tests only focus on generic MPI functionality as it is one complex and critical component of an HPC platform. The unit tests include, for example, compilation with mpicc and distributed execution with mpiexec. It has been applied successfully on the HPC platforms of the University of Luxembourg to assess builds of OpenMPI, MPICH, MVAPICH2 and IntelMPI generated with EasyBuild. In the future, we consider extending our unit tests to validate more components like compilers, libraries, toolchains and even applications. Another future direction is to consider performance validation and regression. [less ▲]
