Since the 1980s, parliamentary technology assessment (PTA) institutes have emerged across Europe, typically with the aim of advising parliaments about the potential social, economic, and environmental implications of sciences and technologies. While until recently, these institutes appeared to have established themselves as dependable partners for policymakers, PTA is increasingly under threat from funders, as illustrated by the Danish Government’s call to disband the Danish Board of Technology and the Flemish Government’s decision to restructure the Flemish Institute Society and Technology (IST). It is hence uncertain whether these institutes will continue to fulfill their present functions as independent policy advisors and think tanks, and as catalysts for public debate. In this paper, we describe the difficulties Flemish PTA, and the IST in particular, faces today. Drawing on arguments and counterarguments to close down and/or reform the IST, we lay out envisioned futures for PTA in Flanders. From a concern with making PTA more visible and potent as a policymaking instrument, we distinguish four grand challenges PTA practitioners and advocates face: (1) increasing the public visibility of PTA; (2) ensuring the uptake of PTA ideas in science and technology discourses; (3) forging closer ties between PTA, academia, and industry; (4) inciting continuous reflection among PTA advocates about PTA aims, methods, and programs. Addressing these challenges will strengthen the PTA knowledge base and effectively align PTA with existing science governance discourses, such as responsible research and innovation, participatory science communication, and public dialogue.

La diversité biologique s’entend bien au-delà de la notion d’espèce. Elle englobe ainsi toutes les particularités du vivant, telles les adaptations locales, les voies de développement alternatives et les tactiques comportementales. Le Triton alpestre est une espèce d’amphibien largement répandue en Europe où il peut être rencontré dans une multitude d’habitats. Sa persistance dans un grand nombre de conditions environnementales lui confère le plus souvent un statut d’espèce apparemment non menacée. Mais au-delà de ce constat, cette espèce présente des spécialisations des plus intéressantes dont certaines pourraient être perdues suite aux pressions d’origine anthropique. Ainsi, le Triton alpestre requiert certaines compositions et configurations d’habitats, tant aquatiques que terrestres. Selon celles-ci, il peut montrer différents patrons de fidélité au site. Son régime alimentaire englobe une multitude de proies mais en fonction des opportunités présentes, il peut adopter des tactiques prédatrices ciblées. Au niveau des interactions sexuelles, les mâles adoptent des parades particulières en fonction des circonstances, telle une femelle peu réceptive par exemple. Dans la majorité des cas, les larves, issues d’œufs pondus dans le milieu aquatique, se métamorphosent en juvéniles qui mènent dès lors une vie terrestre. Mais dans diverses populations, en particulier au sud de l’Europe, il en est tout autrement. Ainsi, certaines larves continuent à grandir tout en conservant leurs branchies ; devenant dès lors aptes à la reproduction. Il en résulte une coexistence de deux formes alternatives : les métamorphes et les pédomorphes. Quoique d’une même espèce, ces deux formes présentent des différences qui sont d’une ampleur voisine voire supérieure à celles rencontrées entre espèces. Selon l’hétérogénéité spatiale et temporelle des habitats, les deux formes présentent des avantages particuliers pouvant expliquer le succès prépondérant de l’une sur l’autre. Les caractéristiques de développement sont aussi variées selon les environnements : acquisition précoce de la maturité sexuelle et métamorphose au stade adulte en fonction d’aléas environnementaux. Une menace particulière pèse cependant sur cette diversité intra-spécifique : l’introduction de poissons. Celle-ci pourrait amener à transformer ce polyphénisme en un monomorphisme où ne subsisterait que la forme métamorphosée, dispersante. En effet, les introductions répétées de poissons dans les environnements aquatiques, quels qu’ils soient, entrainent davantage la disparition des pédomorphes. Les métamorphes, quant à eux, sont également atteints mais peuvent subsister dans certaines conditions qu’il reste à déterminer. [less ▲]

How can scientific statements be made in which molecules or bacterial strains figure as active food constituents, contributing to human health beyond basic nutrition? This paper traces the specific historical and political circumstances that gave rise to the above question, and how the issue is played out in the EU at present. Special attention goes to the European health claims regulation that is in the course of being implemented today. Often referred to as a 'learning process', this implementation has proven to be very difficult and sometimes conflictual, especially regarding claims related to the human intestinal flora. Here, the nature of scientific evidence and the boundary between food and medicine have become the stakes in discussions and contestations between the European Food Safety Authority (EFSA), new emerging groups such as 'gut health' scientists, and scattered critical voices throughout the Member States. Next to a subject of actual research, the 'gut' becomes a space of symbolic investment where 'good' and 'bad' bacteria echo the rivaling conceptions of good and bad science between the actors involved in the production and evaluation of health claims. It will be shown that in addition to the rise of new professional identities, these frictions are also changing the meanings of 'nutrition' and the clinical trial. [less ▲]

What does it means for local residents to account publicly for olfactory nuisances in their environment, to share their experiences, and, above all, to render objectivable what could appear, at first glance, as sheer subjectivities? Relying on an Actor-Network Theory (ANT) approach to technical democracy, a Belgian case study where knowledge co-production between citizens, university, and a spin-off enterprise is described and debated. Between the odor emission source (industry, waste disposal,…) and the odor immission realities (reception) there are an heterogeneity of both natural and social factors that render the flux of odorous molecules more or less challenging to trace. This story is about both technical and social traceabilities. This story is about the intimate, but problematic, relations between electronic noses and human lookouts (Vigies), where the identity of impacted residents and the aerial characteristics of the odors are closely related. The very intimate (recalcitrant) trajectories of air causes interesting mode of associations between key protagonists: a change in the protocol of measurements and it’s the nature of the relations between them that is transformed. In terms of governance, the direct involvement of citizens in the odor monitoring in direct collaboration with the industry (odor source) offers a kind of “management of proximity” that contrasts with the more classic mode of regulation by public authorities.

Les délits sexuels commis par les adolescents suscitent de nombreuses réactions allant de l’incompréhension à l’effroi et laissent place à un questionnement sur la compréhension du passage à l’acte de ces jeunes, sur leur fonctionnement psychologique ainsi que sur les mesures judiciaires et thérapeutiques à prescrire. Les recherches psycho-criminologiques en délinquance sexuelle juvénile se sont centrées sur la question de savoir si les adolescents auteurs d’une infraction à caractère sexuel constituent une population spécifique ou s’ils présentent les mêmes caractéristiques de fonctionnement antisocial que les adolescents auteurs de délinquance non sexuelle. Par ailleurs, tous les auteurs et cliniciens s’accordent sur le fait que les adolescents auteurs d’une infraction à caractère sexuel forment un groupe hétérogène. Dans le cadre de notre exposé, nous allons explorer la question de la spécificité de la délinquance sexuelle en analysant le profil psychologique, l’engagement délinquentiel et sexuel de ces adolescents, en distinguant les adolescents agressant des enfants plus jeunes (child abusers) des adolescents agressant d’autres adolescents (peer abusers). Les résultats de nos recherches indiquent un mode d’engagement sexuel spécifique aux adolescents délinquants sexuels, mais un engagement délinquentiel synchrone et de même nature pour les adolescents délinquants non sexuels et les adolescents délinquants sexuels envers les pairs, qui présentent le plus souvent des trajectoires délinquantes mixtes (délinquance sexuelle et non sexuelle) plus diversifiées et chargées que les adolescents délinquants sexuels envers enfants. L’analyse comparative des profils de personnalité de ces adolescents relève la spécificité de ces deux sous-groupes (child abusers versus peer abusers) et appuie la nécessité de développer des réponses thérapeutiques adaptées à leurs déficits et leurs besoins.

Un haut niveau d’anxiété entraîne des symptômes physiques et cognitifs. Cet état émotionnel peut se répercuter sur les caractéristiques acoustiques de la voix. Cette étude vise à observer l’impact d’une situation stressante sur la justesse d’une performance vocale. 31 étudiants (deux niveaux différents) recrutés au sein des Conservatoires Royaux de Belgique ont chanté une mélodie à trois moments de l’année : deux fois en situation calme (T1 et T3) et une fois en situation anxiogène (T2), c’est à dire le jour de l’examen. Nous avons contrôlé le degré d’anxiété par la mesure de la fréquence cardiaque. Un questionnaire nous renseigne sur l’intensité des symptômes cognitifs et somatiques perçus par les étudiants et leur direction (altérant ou facilitant). La précision des intervalles et le maintien de la tonalité ont été mesurés pour chaque production. Nous comparons les scores obtenus lors d’une situation calme et lors de l’examen. Nous observons que la fréquence cardiaque augmente significativement en situation anxiogène (F(2,90) = 12.60 ; p < .001). L’intensité des symptômes cognitifs et somatiques est plus élevée lors de la situation anxiogène mais l’évolution des symptômes somatiques entre T3 et T2 est plus importante pour les étudiants de 2ème année par rapport aux étudiants de 1ère année. Concernant la justesse, les résultats indiquent qu’un état de stress induit une meilleure précision des intervalles chez les étudiants de 1ère année (p = .02) mais altère le maintien de la tonalité chez les élèves de 2ème année (p = .01). En conclusion, une situation d’examen entraîne une augmentation de la fréquence cardiaque mais l’interprétation des symptômes somatiques dépendrait du niveau d’étude. Les conséquences d’une situation anxiogène, tel un examen de solfège, sur la justesse d’une performance vocale, peuvent être bénéfiques mais sont négatives lorsque l’enjeu est important. [less ▲]

Parenting support has been placed on the political agenda in Europe for the last decade (OECD, 2008, 2009 ; Eurofund, 2011). But a close look to the major discourse can reveal that the interest is very often linked to a compensatory vision of a so-called « deficiency » on behalf of some parents (social control). The symposium has proposed to explore the notion of « meeting places for children and parents » : their characteristics, the driven goals, the values shared by professionals . These places where parents can share « hic et nunc » their own experiences and expertise as parents (not in a preventive purpose) are considered as possible ways of questioning the compensatory approach. Characteristics of meeting places as learning communities have been displayed through a presentation of inspiring practices from different contexts: Italy, Flanders and Federation Wallonia-Brussels. Informal social networks among parents and children are an important source of parental support. Meeting places are settings where such informal networks and social cohesion are facilitated among families with diverse backgrounds. The staff (both professionals and volunteers) plays an important role in facilitating the informal contacts between parents and children. Their role as a “host” (instead of being pedagogical experts) demands specific individual competences and systemic conditions. [less ▲]

Dans le contexte actuel de mondialisation, la turbulence des marchés engendre une concurrence croissante entre les entreprises. En vue d’assurer leur pérennité, il devient essentiel pour les organisations d’avoir recours à la veille stratégique, et particulièrement la veille concurrentielle à savoir le processus par lequel les organisations collectent des informations sur les concurrents et l’environnement concurrentiel (Wright, Eid & Fleisher, 2009, p.942). L’objectif de la présente recherche est de contribuer, au niveau wallon, à l’aspect quantitatif de la littérature relative à la veille stratégique et d’examiner la relation entre les variables contextuelles (la structure formelle, l’implication du personnel et la culture organisationnelle) et le processus de veille stratégique. Elle vise également à améliorer les pratiques de veille grâce à une meilleure compréhension de l’impact des variables de contexte sur le processus de veille stratégique. A ce titre, 81 dirigeants de PME ont été interrogés sur le processus de veille mis en place au sein de leur société. On constate dans cette première étude belge que la plupart des PME wallonnes n’ont pas recours à un processus de veille stratégique. De plus, concernant l’influence du contexte organisationnel sur le processus de veille, nous avons démontré qu’une meilleure structure formelle, l’implication du personnel ainsi qu’une culture d’entreprise tournée vers la veille stratégique améliorent le processus. Par ailleurs, les entreprises de taille moyenne et celles orientées vers l’innovation ont davantage recours à la veille stratégique que les petites entreprises ou celles avec une stratégie d’imitation.

Les plaies traumatiques ou chirurgicales nécessitent souvent une cicatrisation par seconde intention lorsque la fermeture primaire n’est pas possible ou échoue. La fermeture assistée par le vide (Vacuum Assisted Closure : VAC) est une méthode active et non invasive qui expose le lit de la plaie à une pression sub-atmosphérique locale afin de promouvoir sa cicatrisation. Elle stimule la granulation et la perfusion sanguine locale et réduit significativement l’œdème et la charge bactérienne.1 Cette technique s’est révélée efficace dans le traitement des plaies aiguës et chroniques chez l’homme. Chez le cheval, la méthode est encore peu décrite.2,3 Nous rapportons ici l’application et les effets de la thérapie des plaies par pression négative à travers les cas traités à la clinique vétérinaire universitaire de Liège depuis 2010. Les plaies étaient chirurgicalement débridées avant l’application du système VAC. Une mousse en polyuréthane était appliquée après avoir été adaptée à la géométrie de la plaie. Un champ plastique adhésif était alors apposé sur la plaie pour créer un environnement hermétique et un orifice d’1 cm2 était créé au centre du système pour appliquer la ventouse du tuyau d’aspiration. Cette ligne était alors raccordée à l’appareil d’aspiration contrôlée pour maintenir une pression continue de -125 mmHg dans la plaie. Quinze cas ont été recensés: 3 plaies intra-articulaires (au carpe, au coude et au grasset), 3 sur la face dorsale du canon postérieur, 2 sur la face dorsale du jarret, 1 sur la pointe du calcanéum, 2 sur l’encolure et 4 plaies de laparotomie infectées. Le traitement a accéléré la croissance du tissu de granulation, stimulé la contraction des plaies et favorisé la cicatrisation dans la majorité des cas (12/15). Les plaies apparaissaient aussi plus saines et présentaient moins de sécrétions lors des changements de bandages. Des résultats plus modérés ont été notés chez les 3 autres cas. Quelques complications mineures comme des irritations cutanées ont été observées. Le traitement de plaies contaminées nous a orientés vers l’usage d’une mousse de polyuréthane argenté mais d’autres types de matrice sont disponibles et permettent de modifier le comportement de la plaie. L’usage d’une mousse de polyvinyl Alcool s’est ainsi avéré efficace pour améliorer l’adhésion des greffons lors d’une greffe de peau chez le cheval.3 La principale limite du traitement réside dans la difficulté technique de maintenir la plaie sous vide lors d’atteinte de régions très mobiles comme les articulations. En conclusion, le système VAC semble très prometteur pour optimiser la qualité de la cicatrisation et réduire la durée de l’hospitalisation. 1 - Morykwas, M.J., Argenta, L.C., et al.

Introduction: Les kératomes, masses hyperplasiques de kératine, croissent entre la phalange distale (P3) et la paroi du sabot et provoquent des boiteries chez le cheval. La littérature comporte de nombreux rapports de cas isolés mais peu de séries cliniques. Matériel et méthodes: Les dossiers cliniques des cas de kératomes présentés depuis 2004 à la faculté de médecine vétérinaire de Liège ont été revus. Résultats: Vingt-trois kératomes ont été diagnostiqués sur 19 chevaux boiteux. Un cheval présentait 2 kératomes sur le même pied et 3 chevaux présentaient 2 kératomes sur des pieds différents. Sur les 22 pieds atteints, les lésions observées étaient: un abcès, souvent récidivant (18 cas), une déformation de la muraille (6 cas), une déviation de la ligne blanche (6 cas) et une seime (3 cas). Un kératome était situé sous la sole et 22 sous la muraille. La durée des symptômes variait de 2 semaines à 15 ans (plus d'un an sur 12 pieds). Sur les radiographies, une lyse par compression de P3 était visible en regard de 20 kératomes. Le cheval présentant 2 kératomes sur le même pied a été euthanasié. Trois kératomes ont été traités de manière conservative. Dix-huit kératomes (chez 16 chevaux) ont été excisés chirurgicalement dont 16 par avulsion complète de muraille, 1 par avulsion partielle de muraille et 1 par curetage d'une portion de sole. Aucune complication postopératoire n'a été observée dans 7/18 cas (39%). Les complications rencontrées étaient: une granulation excessive (10 cas), une douleur importante pendant plusieurs jours (5 cas), une légère infection (4 cas), un enfoncement de P3 en regard de la zone avulsée (2 cas) et une récidive (2 cas, dont 1 a été réopéré avec succès ultérieurement). Un cheval est encore en convalescence au moment de cette étude. Le suivi à long terme d’un cheval a été perdu. Des 14 chevaux repris dans l'évaluation postopératoire, 1 a été euthanasié pour une autre raison que le kératome, 3 chevaux ont gardé une boiterie résiduelle au trot et 10 chevaux ont récupéré leur niveau d'activité. Discussion: La littérature décrit les kératomes comme rares1. Or, 21% des chevaux de cette étude (4 chevaux sur 19) présentaient plusieurs kératomes. De plus, dans 54 % des cas, les symptômes duraient depuis plus d’un an. Dès lors, il apparait que les kératomes sont sous diagnostiqués ou le sont souvent tardivement. La chronicité et l’étendue des kératomes de cette étude n’a que très rarement permis leur résection par avulsion partielle de muraille, technique de choix dont les complications postopératoires sont moindres². Un diagnostic précoce par inspection minutieuse des sabots, particulièrement en cas d’abcès de pied récidivant permettrait une excision par une technique moins invasive, qui diminuerait la convalescence et les complications postopératoires.

Les objets jouent un rôle de premier plan dans les Physiologies parisiennes des années 1830 et 1840.

Avant d’examiner quelques-unes des fonctions sémiotiques et discursives de ce traitement des objets en rapport avec une poétique d’écriture situable entre le journalisme satirique, le détournement ludique de l’étude de mœurs et une forme de paralittérature politiquement engagée contre le régime de Juillet, cette communication rappelle brièvement le contexte sociohistorique de promotion de l’objet dans lequel s’inscrit la diffusion de ces Physiologies.

Deformation metrology of complex and large space reflectors is a recurrent problem addressed by ESA. The challenging tasks of on-ground qualification and verification testing are to achieve the required accuracy in the measurement of these reflectors deformation and to verify their performance under simulated space conditions (vacuum, low temperature). A long-wave infrared digital holographic interferometer for the verification and validation of this type of reflector in a space environment is presented. It has been developed to fill the gap between holography/interferometry techniques in the visible wavelengths and methods based on structured light illumination like videogrammetry, stereocorrelation, and fringe/pattern projection. The former provide a good measurement uncertainty but the displacements are often too large to be measured and they require a very stable environment, while the latter provide large measurement range but with higher measurement uncertainty. The new instrument is based on digital holography and uses a CO2 lasers emitting at 10.6 µm combined with a commercial thermographic camera. A diffuser is illuminated by the laser beam, producing a speckle wavefront which is observed after reflection on the reflector surface. This reflected speckle wavefront behaves exactly as if the reflector was a diffusive surface, producing its own speckle, allowing the measurement of its deformation. The advantage of this configuration compared to a classical interferometer working at 10.6 µm, is that it requires no specific optics such as a null lens (in the case of parabola) or expensive illumination/collection optics (in the case of ellipse). The metrological certification of the system was performed in the laboratory by measuring the tilts of a 1.1 meter diameter parabolic reflector. The displacements are measured in parallel with a Doppler effect interferometer and the measurement uncertainty is estimated. The application of the new interferometer to the measurement of an elliptic reflector is also presented. The technique has been certified during a thermal-vacuum test. The deformation of the parabolic reflector is measured for a temperature variation from 288 K down to 113 K. The results are compared to previous results obtained on the same reflector with a high spatial resolution infrared interferometer, also developed at CSL. [less ▲]

BACKGROUND GBS are still the leading cause of severe neonatal disease. Screening for vaginal-rectal GBS colonization in pregnant women at 35-37 weeks of gestation, followed by intrapartum antibioprophylaxis to colonized women has proven to be the most effective strategy for prevention of perinatal GBS disease. Despite GBS improved culture method, predictive values (PV) of prenatal screening for GBS colonization at delivery remain limited and contribute to ongoing disease. Switching from time-consuming cultures to a rapid molecular based assay for prenatal screening could be considered: a new assay, the illumigene® Group B Streptococcus (illuB) from Meridian Bioscience, based on LAMP technology is awaited to improve antenatal screening sensitivity. OBJECTIVE To evaluate the illuB performed on culture obtained by 18-24 hours incubation of vaginal-rectal swab in Lim broth versus the reference culture for GBS screening. To determine if and how the illuB may be integrated in the current recommended screening strategy. METHODS Vaginal-rectal specimens collected from 242 pregnant women, were sent to and processed by the labs of the University Hospital of Liege and Hospital Sint Lucas of Gent to determine the status of GBS colonization by the reference culture method for prenatal GBS screening and by illuB. Cultures were performed by direct plating onto Granada agar and inoculation in a selective enrichment Lim broth subsequently subcultured after overnight incubation onto Granada and StrepB Select agar. All illuB were performed from the same incubated Lim broth. Discrepant results were controlled by a PCR assay detecting a gene different from the target of the illuB. RESULTS GBS were recovered in culture from 20.7% of the specimens. By comparison with culture, sensitivity and specificity (S, Sp) of the illuB for identifying GBS colonization were 90% and 98.9%. The positive and negative PV (PPV,NPV) were 95.7% and 97.4% respectively. Among the discrepancies, the 2 illuB positive/culture negative results were also tested positive by the control PCR assay, confirming the presence of GBS DNA even if GBS were not cultured from these specimens. Overall for GBS detection, Sp and PPV were 100%. Out of the 5 false negative illuB, 3 matched cultures with very rare GBS meaning that GBS could have been absent in the aliquots used for illuB. Therefore, S and NPV of the illuB for the detection of GBS are probably higher than 90.4% and 97.4%. CONCLUSION The illuB demonstrated S and Sp close to those of the reference culture method and did not significantly improve the GBS detection. The higher cost of such molecular test may be an obstacle to its wide use as there is not a net benefice when compared with culture method; but a shorter turnaround time and limited hands on time could balance positively the decision. Additional clinical trials are needed. [less ▲]

Aesthetic results in implantology are determined by the harmony between the dental prostheses and the soft tissues. To reach an optimal result, each single step of the treatment has a great importance, from the smile analyses to the final restoration delivery. The goal of this lecture is to describe how to elaborate a treatment planning for single and multiple tooth replacement in the aesthetic zone. A decision tree for the surgical protocols will be proposed according to our clinical experience at the university of Liège and, the current scientific evidences. The biological concept of the use of biomaterial in extraction socket preservation and bone regeneration will be also discussed. The overall objective is, from an initial clinical situation, to determine the appropriate treatment approach. [less ▲]

Background Despite recent improvements in prevention, medical treatment [1]and endovascular aortic repair , invasive surgery associated with cardiopulmonary bypass (CPB) remains the best option of treatment for some patients. The aim of this study is to make a review of the specific CPB protocols associated with these invasive surgical approaches, based on our clinical experience and according to the recent literature. Up to now, these protocols are not supported by evidence based in medicine (EBM) [2] or in perfusion (EBP). Discrepancies can be observed regarding target temperature , selective cerebral protection , CPB circuit concept and arterial cannulation sites . Variables guidelines are suggested concerning regional flow , transfusion requirements [3], coagulation monitoring blood gas management[4] as for cerebral and CPB monitoring tools. Conclusions In the absence of EBM and EBP in the aortic surgery field, the short and long terms clinical outcomes of the patients elected to invasive surgery for aortic diseases must guide and substantiate our choices of techniques and of CPB protocols.

As a narrative pattern and a cultural motif, the confusion between fictional worlds and reality traditionally leads to metaphysical arguments about liberty and destiny. Despite their drawing heavily on scientific imagination and technoscientific artefacts, science fiction movies exploring that theme never really broke with the way it has been treated since Calderon de la Barca’s Life is a dream: the hero’s quest leads him to doubt his own identity and dispute the ontological status of the world he lives in, leaving him and the viewer perplexed as to the ultimate nature of things. Yet, in the last fifteen years, an increasing number of science-fiction movies renewed that interrogation, notably by placing the issue of design at the centre of the plot: fictional worlds are not only denounced as fictional, but also shown as works in progress, literally rebuilt according to the plan of not-so-hidden designers acting as demiurges. In Dark City, Vanilla Sky or, more recently, Inception and The Adjustment Bureau, the emphasis on design and architecture together with the use of computational metaphors result in the promotion of one particular world to the status of “reference” universe, to be held as more “real” than other, fabricated and computed worlds made accessible by sophisticated devices operating as metaleptic instruments (such as Neo’s cable plug or the “bio-ports” in ExistenZ). This paper wishes to explore this shift towards “gnostic", Matrix-like science-fictional narratives, particularly in relation to the dramatic development of networking and surveillance capabilities that occurred during the same period.

Current practice in industry is to rely on linear finite element simulations. However, nonlinearity is a frequent occurrence in engineering structures. It is at the origin of rich and complex dynamical phenomena that cannot be observed in linear structures. Solving both the direct and inverse problems in nonlinear structural dynamics therefore warrants the development of appropriate methodologies. The focus of the presentation will first be on the inverse problem. We will describe the different steps of the nonlinear system identification process and discuss the current capabilities of existing methods. The presentation will then address the direct problem during which the identified model is used for accurately predicting the structure’s dynamic characteristics. A rigorous nonlinear extension of modal analysis will be presented, and we will show that it represents a very useful framework for understanding nonlinear dynamical phenomena and supporting design decisions. Two real-life aerospace structures will be considered for illustrating the proposed developments. [less ▲]

This paper dealt with the research I carried out on domestic architecture and private economy during Early Bronze Age in Upper-Mesopotamia. Archaeological records, as well as textual evidence, has been used to try to define private households activities and their relationships with official institutions. Households were the main source of production, distribution and consumption during the Early Bronze Age. As it seems that these private economic entities produced goods and crafts in their own houses, analyzing domestic architecture could be a way to approach Mesopotamian economic activities. In Northern Mesopotamia the economic system was already strongly articulated; beyond palatial organizations it was also largely based on private group activities, often structured by kinship.

An elaborated approach to creating a reference terminology has been developed. First, terms are selected from everyday interactions between doctors (occurrences in medical records, in guidelines), based on frequency count and relevance. Then an onomasological approach is applied to make a choice on basic concepts most intricately related to the most common sense of the selected terms. If possible a perfect concordance for that concept is looked for in the SNOMED nomenclature, and if not possible, in UMLS nomenclature, or genuinely defined. The nature of the mapping from the concept in the reference terminology to external international classification is qualitatively rated (exact, nearly exact, match to higher or lower level of granularity). In addition, each concept in the Reference Terminology (RT) is also mapped to classifications such as ICPC, ICD. Mapping to thesauri (MeSH) and other nomenclatures (LOINC, NANDA) is foreseen.

Asperity flattening has a huge influence on friction and wear in metal forming processes. Nevertheless, phenomena that occur at the microscopic scale are still not well understood. Since no experiment can be easily performed in real forming conditions, numerical models are essential to achieve a better knowledge of what happens in these contact regions. In this paper, a threedimensional model of a rough strip flattened by a rigid rough tool is presented. The boundary conditions applied to this model correspond to the ones encountered in a real cold-rolling case. The results are compared to experimental measurements from the pilot mill of ArcelorMittal Maizières R&D. [less ▲]

This symposium proposes presentations related to nurse educators competencies and the challenges links to their new roles. The evolution of the nurses training at the European level asks the teacher to develop high-level disciplinary skills but also educational skills. There are lots of challenges to develop nurse educator competencies. The role of the teachers is not any more to transmit disciplinary knowledge but to become experts in group management, colleagues teamwork, reflective practice, and construction of active learning situations in a socio constructivist model. These changes of roles also have an impact on the professional identity of the teachers. The various presentations will approach successively these ideas: 1. A proposal for a Competencies Benchmarking of Nurse Educators The aim of this presentation is to characterize the nursing teachers concepts on their professionalism,roles, competences and their identities construction. 2.

The submarine part of the North Anatolian Fault (NAF) is a very significant hazard for the 12 million people living in Istanbul (Turkey). An accurate seismic risk assessment necessitates paleoseismological data, which can be retrieved in the Marmara Sea by using sedimentary cores. We present here a record of turbidites obtained in cores spanning the Tekirdag ̆ Basin, the Western High, the Central Basin, and the Cinarcik Basin. In the Tekirdag and Western High the turbidites are synchronous pointing to shaking by earthquakes as a triggering mechanism. Generally seismoturbidites in the Marmara Sea are distinguished from other turbidites based in their large extension, their particular granulometric and their particular geochemical characteristics. The 210Pb and 137Cs radionucleides measurements have also shown that the M=7.4 1912 Mürefte earthquake and the M=7.3 1894 Prince's Island earthquake have left a distinctive sedimentary imprint at the top of the studied cores. The chronology of other seismoturbidites is built combining radiocarbon dating and secular variation patterns of paleo-declination and paleo-inclination. Finally the obtained record is compared to the historical seismicity record. [less ▲]

Shallow lakes along minor structural bends or discontinuities of strike-slip fault are not usually paleoseismological target sites. In the present talk we show that a 2m deep, 700m long lake crosscut by the eastern segment of the North Anatolian Fault contains a reliable paleoseimological record obtained through coring. The North Anatolian Fault, a major strike-slip fault in Turkey, last ruptured across the Aşağıtepecik Lake in 1939 with a slip of about 6 m. Seismic lines still show remains of the fault rupture forming minor scarps across the lake. Collected short cores display a set of sedimentary sequences. Each sequence is composed of similar organic rich sedimentary units. The lower unit is dark and fibrous, and is similar to the present sedimentation at the top of the core. The upper unit is disturbed and has anomalous organic matter content, grain size and mineralogy. It is interpreted as an earthquake induced sedimentary event. The 2.5 m long AT2007LG core comprises four sequences, and four sedimentary events. Radiogenic 210Pb and 137Cs data obtained in Boes et al. (2009) imply that the shallowest event 1 was triggered by the 1939 M=7.9 Erzincan earthquake. Radiocarbon dating suggest that events 2 and 4 were initiated by the 1668 and 1254 historical earthquakes. The event 3 does not correspond to a large historical earthquake on the NAF. The record can be compared to a classical paleoseismological study located about 2.5 km more to the east. The investigation comprised three paleoseismic trenches located along about 2km of the principal fault strand. Trench T1 revealed clear evidence for one earthquake interpreted to be the 1939 Erzincan earthquake. Trench T2 revealed evidence of three earthquakes. Trench T3 revealed a record of colluvial wedges that interfinger with fine-grained inter-fan deposits. We interpreted a sequence of six earthquake event horizons including the 1939 Erzincan earthquake. The first three earthquakes are correlated to historical earthquakes in A.D. 1668, 1254, 499 and two further events were identified at 881 – 673 B.C. and 1406 – 1291 B.C. (2σ age ranges). By comparing all available earthquake timing studies,we conclude that the 1939 earthquake segment does not always rupture in unison. [less ▲]

Cela fait maintenant plus de 20 ans que l’affaire du voile a éclaté en Belgique pour la première fois, contaminée par le débat public ouvert en France après l’exclusion du lycée de Creil de trois jeunes qui portaient le hijab. Comme en France, depuis 1989 la question du hijab apparaît et disparaît de la scène médiatique belge par intermittence. À la différence de la France, qui en 2004 se penche sur la question afin de trouver une solution juridique fermant définitivement la controverse, la question du hijab à l’école va rester perpétuellement dans le débat belge par manque de solutions politiques. Toutefois, si dans un premier temps la question du hijab se posait uniquement dans les écoles, à partir de 2004 le débat s'élargit et concerne peu à peu les administrations publiques, les salles de justice ou le Parlement, avant d’occuper la totalité de l’espace public avec la question de la burqa.

Although karstic weathering (sensu lato) is a major concern for the exploitation of limestone quarries, the importance, spatial extension, and intensity of this natural phenomenon are rarely investigated because of the lack of applicable technique to assess these variables other than subsurface geophysical exploration methods. Here, we propose to use the intrinsic property of ghost-rock weathering, tectonic control, to predict the degree and type of weathering of the reserve of two contiguous limestone quarries in the Tournai area (western Belgium). First, we revised the macrotectonic setting of these quarries, creating five tectonic entities. Then, we built an extensive fracture database (1357 ‘events’), recording fracture direction, dip, width, height, mineralization, and weathering. Then, we calculated a “Sterile Index” that is a simple function of the relative occurrence and mean width of karstified fractures. The rose diagrams of fracture orientations are contrasted between tectonic entities and so are the intensity and the dominant type of weathering: tectonic entities with widely dispersed fracture directions are significantly more weathered than entities with narrowly dispersed rose diagrams. Preliminary tests indicate fracture orientation and weathering are consistent within the tectonic entities, allowing extrapolation to quarries reserves. Ultimately, this technique can be used to predict the rock waste volume of the quarries reserves (when combined with geophysical exploration methods) and manage the development of the quarries accordingly.

Nous avons réalisé une étude qualitative sur l'attitude des personnes dépendantes de l'héroïne envers ce type de projet, ainsi que sur l'attitude des intervenants d'institutions de soins travaillant avec ces personnes Méthode : Avant qu'un patient ne soit inclus dans le projet TADAM, il lui était demandé d'expliquer pourquoi il souhaitait rentrer en traitement (n=80). Des interviews ont également été réalisées auprès de consommateurs d'héroïne non inclus dans le projet, avant la période d'inclusion (n=65), au milieu de celle-ci (n=30) et dans ses derniers mois (n=23). Pendant le projet, des interviews ont également été réalisées auprès d'intervenants travaillant dans des institutions de soins pour personnes dépendantes de substances, soit de manière individuelle (n=10), soit en groupe (n=6) pour connaître leur attitude face au projet TADAM. Résultats : De nombreux patients souhaitaient rentrer dans ce projet pour améliorer leurs conditions de vie. La raison principale de ne pas rentrer dans ce type de traitement était la peur de devenir plus dépendant. Cette raison était renforcée par le fait que le traitement par héroïne proposé ne durait que 12 mois et les patients s'inquiétaient de leur situation après ce traitement : ils avaient peur d'être plus dépendants et donc dans une situation plus difficile qu'avant le traitement. L'attitude des intervenants étaient plutôt favorable mais prudente. Conclusion : Contrairement aux craintes préalables, les usagers d'héroïne ne se précipitent pas en masse et sans réfléchir vers un traitement assisté par héroïne. Certains réfléchissent longtemps avant de s'y engager. Une information précise et un traitement sans durée minimum sont nécessaires. [less ▲]

Gallery excavation in clayey rocks induces stress perturbations that trigger damage propagation. The excavation process creates then the so-called excavation damaged zone in which properties are modified. The prediction of the extension and especially of the fracturing structure in this zone remains a crucial issue in the context of underground storage. Since strain localization in shear band mode is frequently observed in experimental works, the excavation damaged zone can be modeled by considering the development of strain localization bands. A hydro-mechanical modelling of a gallery excavation is performed. The numerical results exhibit an excavation damaged zone extension similar to the in situ measurements and provides information about the rock state within this zone. [less ▲]

Space electronic systems employ enclosures to shield sensitive components from space radiation. The purpose of shielding is to attenuate the energy and the flux of ionizing radiation as they pass through the shield material, such that the energy per unit mass (or dose) absorbed in silicon is sufficiently below the maximum dose ratings of electronic components. The received radiation amount varies significantly depending on several variables that include mission parameters (orbit, altitude, inclination and duration), spacecraft design (spacecraft wall thickness and panel-enclosure location). To achieve the optimum shielding with the minimum weight, all these variables have to be considered in the design. Energetic particles, mainly electrons and protons, can destroy or cause malfunctions in spacecraft electronics. The standard practice in space hardware is the use of aluminium as both a radiation shield and structural enclosure. Composite structures show potential for significant mass savings. However, conventional graphite epoxy composites are not as efficient shielding materials as aluminium because of their lower density, that is, for the same mass, composites provide 30 to 40% less radiation attenuation than aluminium. A solution is to embed high density (atomic weight) material into the laminate. This material, typically metallic material, can be dispersed in the composite or used as layers in the laminate (foils). The main objective of the “Radiation Shielding of Composite Space Enclosures” (SIDER) project is the development of the technologies and tools required to obtain lightweight, safe, robust and reliable composite structures. Two different strategies are being analysed as alternatives for radiation shielding: and he incorporation of a high density material foil. This paper will present and analyse the radiation shielding obtained by the incorporation of nanomaterials in composite structures. [less ▲]
