This paper develops a probabilistic approach for power system reliability management in real-time operation where risk is a product of i) the potential occurrence of contingencies, ii) the possible failure of corrective (i.e., post-contingency) control and, iii) the socio-economic impact of service interruptions to end-users. Stressing the spatiotemporal variability of these factors, we argue for reliability criteria assuring a high enough probability of avoiding service interruptions of severe socio-economic impact by dynamically identifying events of nonnegligible implied risk. We formalise the corresponding decision making problem as a chance-constrained two-stage stochastic programming problem, and study its main features on the single area IEEE RTS-96 system. We also discuss how to leverage this proposal for the construction of a globally coherent reliability management framework for long-term system development, midterm asset management, and short-term operation planning.

For the JADT 2012, we applied the text pattern theory to Noun-preposition-Noun (NpN) sequences, where both nouns surrounding the preposition are identical. Our working corpus was composed of texts from the four main literary genres, memoirs (109 texts), novels (740 texts), poetry (191 texts) and theater (210 texts), 85 million words, sampled out of Frantext, a categorized database. That exploratory research allowed us to pinpoint the specific place of the NpN sequence, between language and discourse, its blooming into a full discursive pattern, able to produce a stylistic effect linked to lexical innovation, as well as its possible use as a generic litterarity marker. This paper aims at pursuing the work by extending the corpus and proposing new contrastive studies, showing the role of the NpN sequence as a litterarity marker. [less ▲]

This paper focuses on simplified models of the Modular Multilevel Converter suitable for large-scale dynamic studies, in particular simulations under the phasor approximation. Compared to the existing literature, this paper does not a priori adopt the modeling approach followed for the original twolevel or three-level Voltage Source Converter. On the contrary, a model is derived following a physical analysis that preserves its average internal dynamic behavior. An equivalent control structure is proposed and various alternatives are highlighted. The proposed model with its controllers has been implemented in a phasor simulation software and its response has been validated against a detailed Electromagnetic Transient model. Finally, an illustrative example is presented with the application of the proposed model on a large grid consisting of AC areas interconnected with a multi-terminal DC grid. [less ▲]

Animal and plant proteins are major proteins sources in the human diet. After their enzymatic degradation in the upper gastro-intestinal tract, the undigested fraction of these proteins is available for fermentation by the microbiota of the large intestine leading to the production of short-chain fatty acids (SCFA), branched-chain fatty acids (BCFA), ammonia, biogenic amines, sulphur metabolites, phenols and indoles. As some of these compounds have genotoxic and cytotoxic effects, protein fermentation is considered as detrimental to the host’s epithelial health. BCFA are usually used as a marker of intestinal protein fermentation. We studied in vivo the impact of proteins from animal and plant origin, raw or after a cooking procedure, on the composition of gut microbiota and on fermentation end-products. Weanling rats were used as models of the human gut microbiota. Eight experimental diets were formulated with beef meat (Longissimus dorsi), chicken meat (Pectoralis major), white pea beans (Phaseolus vulgaris), soybeans (Glycine max), used raw and cooked, as sole source of protein in the diet. One casein diet was used as control. All diets, formulated to contain 15% of raw protein, were given to seven rats for four weeks. After euthanasia, caecal contents were collected. Pyrosequencing analyses (Roche 454 GS Junior Genome Sequencer) were performed to study the microbial composition. SCFA and BCFA were measured using HPLC (Waters 2690). Microbial composition in the caecum is associated to the type of dietary protein and to the cooking procedure applied. The proportion of BCFA in the caecal content is mainly affected by the type of protein. So BCFA represent respectively 04-06% and 35-44% of total SCFA with diets based on plant and on animal proteins. In conclusion, both the type of protein and the cooking procedure could impact the gut microbiota in terms of composition and of fermentative capacity. [less ▲]

Cette proposition de communication porte sur une tentative d’appréhender l’évolution d’enseignants en formation pédagogique par le biais d’une analyse comparative de leurs commentaires d’une séquence vidéo présentée en début et en fin de parcours. La vidéo comme support privilégié de l’analyse critique des pratiques enseignantes à des fins de développement professionnel fait déjà l’objet d’une abondante littérature. Nous avons voulu tester le potentiel de cette approche dans le cadre du cours « Description et analyse critique de pratiques d’enseignement et d’évaluation », commun aux formations CAPAES et Formasup organisées à l’Université de Liège. Le cours aborde les thématiques pédagogiques jugées incontournables pour procéder à une planification de qualité d’un dispositif d’enseignement. Les thématiques sont traitées par le biais des représentations spontanées des enseignants-participants et grâce à divers modèles et théories. Quinze enseignants observent et commentent la même séquence vidéo en début (septembre 2015) et en fin de cours (décembre 2015). La première série de commentaires représente leur appréhension spontanée d’une situation de classe « criblée » de maladresses pédagogiques en mobilisant leurs savoirs antérieurs au cours tandis que la deuxième série devrait mobiliser également des savoirs acquis pendant le cours. Il s’agit là d’une hypothèse à vérifier. La communication au congrès AIPU présentera les résultats de l’analyse comparative des écrits des enseignants. Nous pouvons déjà formuler quelques constats relatifs aux commentaires rédigés au temps 1. Les enseignants expriment en moyenne trois à cinq avis critiques pertinents concernant les attitudes de l’enseignant observé. Les élèves sont également critiqués mais des liens de cause à effet entre les comportements respectifs de l’enseignant et des élèves sont rarement établis. Aucune référence explicite à des théories pédagogiques n’est faite et peu de pistes de régulation sont proposées.

For offshore wind turbines, the support structure contributes with a significant part to the Levelized Cost Of Energy (LCOE). LCOE is the total cost to build and operate a whole offshore wind turbine structure over its lifetime divided by the total energy output of the wind turbine over that lifetime. That total expected cost of operation & maintenance may be lowered by application of reliability- and risk-based maintenance strategies and updating of the reliability based on e.g. inspections performed during the design lifetime. Updating the reliability (or alternatively the failure probability) of a welded joint can theoretically be done using Bayesian updating. However, for tubular joints in offshore wind turbine substructure when considering a two dimensional crack growth and a failure criterion combined brittle fracture and material strength, the updating is quite complex due to the wind turbine loading obtained during operation. This paper considers how the reliability (or the probability of failure) of welded steel details can be updated in the case where the fatigue failure is modelled by a fracture mechanics approach and a Failure Assessment Diagram (FAD) is used to define a limit state equation. Besides, it is shown how the probability of failure of fatigue critical joints can be updated for various inspection scenarios. A two dimensional bi-linear model is considered for the crack growth. Calculation of the crack depth and the crack length are coupled. The stress intensity factor is calculated following the sophisticated procedure in BS 7910:2005. The initial crack size, the yield and ultimate strengths of steel, the fracture toughness, the stress intensity factor, and the stress-ranges are considered as uncertain and modelled by random variables. The probability of detection is used to account for uncertainty in crack inspections. By using Monte Carlo simulations, stress-range histories are generated randomly and together with the calculated stress intensity factors used to check the limit state condition using the FAD approach. The probability of failure updating is done for three inspection scenarios: No crack detected; Crack detected and repaired; Crack detected but not repaired. The paper presents illustrative results for offshore wind applications for the three scenarios, including comparisons of application of the FAD approach for modelling the limit state equation with a ‘conventional’ approach where it is assumed that failure happens when crack-depth reaches the plate thickness or the stress intensity factor is equal to or larger than the fracture toughness of the material. Finally, it is discussed how application of the updating procedure can be used for inspection planning for offshore wind turbine support structures, and thus also for reducing the required safety factors at the design stage.

Introduction Raviva is a Belgian adapted physical activity (APA) program for cancer patients and survivors, developed by the Belgian Foundation against Cancer (http://www.cancer.be/aide-aux-patients/la-fondation-votre-service/raviva-bouger-pour-se-sentir-mieux). Activities supported by this foundation are supervised by instructors with inconstant trainings and experiences. Indeed, in Belgium, APA instructors do not necessarily follow specific training programs such those proposed by the ACSM (Schmitz et al., 2010). As it is the case in sport coaches’ education (Erickson et al., 2008), interacting with colleagues and sharing knowledge could be an interesting way to improve APA instructors’ competencies. The aim of this study was to plan and analyse interactive APA working groups, as part of a training day intended for all Raviva instructors. Methods As part of this training, we proposed three practical physical activity working groups, each one concerning a specific activity: fitness, relaxation and aqua-aerobics. They were designed to generate some good practices in intervention with Raviva groups and had to be interactive: all participants had the opportunity to present their own practices and to discuss and comment the practices of the others. Three methods were used to analyse the activities: interviews of the organizers (n=4), a questionnaire for all trainees (n=35) and participant observation. Results Many examples of practical situations and good practices have been identified.79.4% of the trainees considered that the proposed method was interesting and 88.3% mentioned that they have been actively involved. The organizers were less convinced as they highlighted a lack of ideas sharing as well as low active participation and dynamism. Observations confirmed the organizers’ opinions. Conclusions Participants appeared to be globally satisfied with the practical activities. However, further research is needed to measure the impact of such methods on their future practices.

Analogical reasoning development maintains a mutual influence with language acquisition: the use of relational labels helps to resolve analogical reasoning tasks (Christie & Gentner, 2014) while analogical reasoning enables the acquisition of new linguistic concepts or structures (Gentner & Namy, 2006). This link has driven some authors to examine the analogical reasoning ability of children with Specific Language Impairment. Those children have poorer analogical reasoning performance than their age-matched peers without language disorders (Leroy et al., 2012 ; Leroy et al., 2014). So, children with SLI seem to have an analogical reasoning weakness which could be linked to their language disorders. Thus, our goal here is to measure the ability of children with SLI to solve analogies, and to compare it to chronological age-matched but also to linguistic age-matched peers without language disorders. Our hypotheses here are the followings: children with SLI have weaker analogical reasoning competence compared to chronological age-matched peers and similar or weaker analogical reasoning competence compared to language-matched peers. To test these hypotheses, we use a scene analogy task composed of pictures of 20 relations (Richland et al., 2006) varying in relational complexity (binary or ternary relations) and in perceptual distraction. Twenty children with SLI are matched to chronological age and linguistic age peers without language disorders. Children with SLI have poorer performance then their age-matched peers but they have similar performance to their language-matched peers. This data reinforces the idea of a link between analogical reasoning and language, also in children with SLI. However, the nature of this link should still be clarified. [less ▲]

Quelles sont les valeurs professionnelles identifiées et partagées par les encadrants d’un Master Professionnalisant en Enseignement Supérieur (Formasup) ? Les participants y sont-ils sensibles ? Le Master de spécialisation en pédagogie universitaire Formasup, formation diplômante de 60 ECTS organisée à l’Université de Liège, s’adresse à des enseignants du supérieur qui souhaitent s’engager dans une démarche rigoureuse de développement professionnel. Le dispositif de formation est porté principalement par quatre personnes (deux chargés de cours et deux accompagnatrices pédagogiques) et compte une dizaine de participants par an. Les enseignants-participants entrent dans le dispositif avec un « cours-projet » pour lequel ils identifient des éléments perfectibles. Ils améliorent ensuite leur cours en y intégrant une innovation pédagogique dont ils tentent d’évaluer l’impact sur la motivation et l’apprentissage de leurs étudiants. Les méthodes employées pour aider les enseignants à développer les compétences nécessaires à cette démarche combinent des séances de cours en présentiel et à distance et prévoient un transfert systématique des apprentissages théoriques au cours projet de l’enseignant. Un accompagnement individualisé est également proposé, une spécificité perçue par les enseignants-participants comme une force. Si le dispositif a bien sûr évolué au fil des années, il nous a aussi donné l’occasion de nous interroger sur nos valeurs et de réfléchir à la manière dont ces valeurs étaient partagées et se traduisaient effectivement dans nos postures, nos actions et nos modalités d’évaluation. ¬¬¬Cette recherche vise à répondre aux questions suivantes : « dans les préoccupations quotidiennes des encadrants, quels sont les éléments qui peuvent être qualifiés de « valeurs » ? Ces valeurs sont-elles réellement partagées par les quatre encadrants ? Quelle perception les acteurs ont-ils de la « traduction » de ces valeurs dans la conception, l’animation et l’évaluation de ce dispositif de formation ? Nous nous centrerons essentiellement ici sur l’analyse des perceptions croisées des encadrants et des participants, obtenues sur la base d’écrits professionnels et de réponses à des questionnaires et entretiens.

Juvenile myoclonic epilepsy is one of the most common forms of generalized genetic epilepsy. Genetic studies have shown that heterozygous mutations in Myoclonin1 are responsible for 3-9% of clinical cases worldwide. This protein contains three DM10 domains of unknown function and an EF-hand domain. We have previously demonstrated that Myoclonin1 is a microtubule-associated protein involved in cell division and radial migration during neocortex development. In cells, this protein co-localized with specific structures rich in microtubules (MTs) such as the centrosome, the poles of the mitotic spindle or the motile cilia but not with cytoplasmic MTs. This suggests post-translational modifications (PTM) of MTs may be important for the interaction between Myoclonin1 and MTs. We have co-express the different enzymes catalyzing PTM of MTs with Myoclonin1 in U2OS cell line. With one of these enzymes, we observed a strong increase in PTM in the presence of Myoclonin-1. This suggests that Myoclonin1 may interact with and modulate the activity of this enzyme. By using luciferase complementation assay and pull down experiments, we could demonstrate that it is indeed the case. Interestingly, the effect is observed even when a DM10 domain alone is co-expressed with the enzyme, suggesting for the first time a role for this domain. In conclusion our data suggest myoclonin-1 modulates specific PTM of MTs. This is of prime importance for microtubule dynamic and notably for neuroblast precursor migration during neocortex development. This could be the mechanism that explains why pathological forms of myoclonin-1 affect brain development. [less ▲]

Dans quelle mesure la littérature est-elle enseignée dans les manuels belges et français contemporains en interaction avec d’autres formes artistiques, qu’elles soient plastiques, visuelles, musicales, architecturales, cinématographiques… ? Voici la question qui s’inscrit au cœur de notre propos. En effet, la présente contribution étudie l’articulation entre littérature et art telle qu’elle se donne à voir dans les manuels belges et français actuels destinés aux élèves du secondaire inférieur (collège) et supérieur (lycée). Pour ce faire, nous commencerons par décliner plusieurs questions de recherches plus circonscrites avant de discuter les concepts-clés de notre problématique. L’étude repose sur des fondements théoriques multiples et hétérogènes, puisqu’ont été convoqués notamment les travaux de Choppin (2005, 2008), de Bautier et al. (2012), de Perret-Truchot (2015) ou de Bonnery (2015). Nos résultats s’appuient sur l’analyse fine de trente-neuf manuels. Si la recherche revêt un caractère exploratoire, les résultats qu’elle a induits invitent à prendre en compte ultérieurement un corpus plus important et suscitent des questions vives, tant du côté de la conception des manuels que de leur réception auprès des élèves, mais aussi des enseignants ou de leurs formateurs.

Le modèle dit de Sherbrooke développé par P. Loisel au Québec constitue le fondement des recommandations internationales en matière de programmes de retour au travail pour les travailleurs souffrant de lombalgie. Ce modèle a inspiré les recommandations belges et françaises (HAS 2013) en la matière. De nombreuses études explorent maintenant la possibilité d’une intervention précoce en milieu de travail – un des axes essentiels du modèle de Sherbrooke - dans d’autres problématiques de santé que la lombalgie, et notamment en cas de décompensation psychique. La combinaison d’une telle intervention avec les approches propres aux milieux de soin représente cependant un réel défi. Le programme de prévention secondaire de la lombalgie initié en Belgique en 2004 dans le cadre de l’assurance maladies professionnelles permet d’illustrer quelques-unes des difficultés à surmonter : information du public-cible (tout travailleur exposé à la manutention de charges et/ou aux vibrations corps-entier) et des médecins traitants concernés, mise en place d’une collaboration, jusque-là inexistante, entre médecins de revalidation et médecins du travail, sensibilisation des employeurs. Même la collaboration entre médecins se heurte à de sérieuses barrières. Elle implique en effet un dialogue et une relation de confiance entre le médecin traitant qui considère prioritairement la protection de son patient, le médecin du travail qui a à juger l’aptitude d’un travailleur pour une activité de travail définie et un médecin-conseil de la sécurité sociale dont la fonction centrale était encore récemment le contrôle du bien-fondé de l’arrêt de travail afin de préserver l’équilibre financier du système. La prévention de la désinsertion professionnelle devrait idéalement constituer un objectif commun à ces trois métiers médicaux mais il s’agit à l’évidence d’un chantier de longue haleine. La décision du gouvernement belge d’instaurer un trajet de réintégration multidisciplinaire au sein de l'Assurance Maladie pour tout assuré en arrêt-maladie depuis 3 mois a révélé, avant même sa mise en application prévue en 2016, les enjeux sous-jacents à un tel projet. Les négociations avec les partenaires sociaux ont abordé plusieurs questions. Veut-on promouvoir plus d’équité sociale, ou simplement limiter l’augmentation alarmante des dépenses d’invalidité ? L’entrée de l’assuré dans le trajet proposé va-t-elle se faire sur base volontaire, ou faut-il prévoir une sanction financière en cas de refus ? A quel médecin confier la direction du trajet ? Quelle place réserver au médecin du travail, et au médecin traitant ? Faut-il prévoir une responsabilisation financière de l’entreprise ou faire confiance à la bonne volonté des employeurs ?

This paper addresses the problem of an aggregator controlling residential heat pumps to offer a direct control flexibility service. The service is defined by a 15 minute power modulation, upward or downward, followed by a payback of one hour and 15 minutes. The service modulation is relative to an optimized baseline that minimizes the energy costs. The potential amount of modulable power and the payback effect are computed by solving mixed integer linear problems. Within these problems, the building thermal behavior is modeled by an equivalent thermal network made of resistances and lumped capacitances whose parameters are identified from validated models. Simulations are performed on 100 freestanding houses. For an average 4.3 kW heat pump, results show a potential of 1.2 kW upward modulation with a payback of 600 Wh and 150 Wh of overconsumption. A downward modulation of 500 W per house can be achieved with a payback of 420 Wh and 120 Wh of overconsumption. [less ▲]

In order to perform the analysis of organic pollutant in trace by Raman spectroscopy, it is necessary to develop SERS substrates, such as noble metal nanoparticles (NPs). The synthesis of gold or silver NPs is used for analytical applications. It is therefore important to precisely control the synthesis of these SERS substrates to achieve reproducible measurements. Microfluidics is a very attractive technology for the control of the synthesis parameters such as temperature, reaction time and mixing conditions which affect both the size and the morphology of NPs. The synthesis of gold or silver NPs in microreactor is a technique we are already developing in the laboratory. We develop a method for the continuous synthesis of gold and silver NPs in a segmented regime capillary microreactor. The residence time and temperature have a significant effect on the size of the NPs, enabling to prepare different sizes of NPs using the same microreactor and the same precursor solutions. [less ▲]

The increased risk of breast cancer and thromboembolism in women who take hormone replacement therapy (HRT) is a major public health problem. The discovery of new drugs with better safety profile would provide useful advances for patient care. Estetrol (E4) is a liver friendly promising candidate for HRT. In preclinical and/or clinical studies, E4 has been effective against the main symptoms of menopause from a starting dose of 0.3 mg/kg/day. The aim of this study was to define the impact of E4 on mammary gland and breast cancer development. Our preclinical data show that E4 is less efficient than estradiol (E2) to induce mammary gland growth. Treatment with several concentrations of E4 has shown that E4 did not increase tumor development, when it is used at 0.3 mg/kg/day. However, at 3 mg/kg/day, E4 increased tumor growth similarly to E2 (0.08 mg/kg/day). E4 presents also some anti-estrogenic effects on mammary gland and antitumor activity on breast cancer by decreasing the strong proliferative effect of E2. While ERα is the predominant receptor mediating its effects, the dual weak-estrogenic/anti-estrogenic feature of E4 results from differential signaling pathways activation. Both nuclear and rapid extra-nuclear signaling pathways are necessary for a complete estrogenic effect of E4. However, the antitumor action of E4 is not due to a capacity to antagonize E2-induced nuclear activity. In conclusion, our results support that E4, if it is used in strictly controlled clinical applications, could have no or only limited impact on breast and breast cancer. [less ▲]

Les recherches sur le contrôle cognitif proposent l’apparition d’un déclin lié à l’âge dans les capacités de contrôle proactif (forme anticipatoire de contrôle comportemental) alors que le contrôle réactif (forme réactionnelle à la détection d’un conflit) semble rester intact [1]. Ces deux formes de contrôle ont été associées à des aires cérébrales différentes [2], cependant peu d’études ont étudié les effets de l’âge sur les régions cérébrales sous-tendant chacun de ces deux types de contrôle. Pour ce faire, une version adaptée de la tâche de Stroop a été administrée à 16 jeunes (18-30 ans) et 16 adultes (60-75 ans) en IRM fonctionnelle. Cette version de la tâche variait la quantité d’items interférents, permettant la création de trois contextes (Mostly Congruent « MC », Mostly Incongruent « MI » et Neutre) favorisant respectivement la mise en place des deux types de contrôle (réactif = congruent / proactif = incongruent). Les analyses ont été réalisées avec SPM8 (p<.001 non-corrigé). Les résultats comportementaux révèlent un traitement plus rapide de l’interférence dans le contexte « MI » que « MC » pour les jeunes adultes uniquement. Au niveau cérébral, le traitement de l’interférence en MI semble associé à une diminution d’activité (surtout à droite) dans les régions frontales et temporales chez les volontaires âgés par rapport aux plus jeunes, alors qu’en MC, les âgés montrent une augmentation d’activité bilatérale au niveau frontal. Ainsi, les résultats comportementaux montrent que les adultes âgés semblent avoir plus de difficultés à implémenter un contrôle proactif (associé à une diminution d’activité) que les jeunes dans les régions sous-tendant la performance à cette tâche. Cependant, le recrutement supplémentaire de régions frontales observé lors du contexte MC postulé pour favoriser le contrôle réactif, suggère la présence de mécanismes de compensation. Pour conclure, le vieillissement semble affecter de manière différentielle l’activité des régions cérébrales sous-tendant les différents types de contrôle. [less ▲]

Objective. The BibliothEP study aimed to assess the efficacy of a bibliotherapy for premature ejaculation (PE) Design and method. The study was conducted in two phases. First, a sample of 120 participants suffering from PE read a concise cognitive behavioural self-help manual for PE (51 A5 pages including illustrations) and were compared after treatment to 66 waiting list controls. Second, 36 subjects received and read the self-help manual and were compared after treatment to 32 subjects having received the same manual plus a complementary brief guidance (45-90 minutes) from a coach not specialised in sex therapy, but who had been specifically trained to support the bibliotherapy intervention (by attending a 5-hour training module). The main outcome measures were self-determined latency time to ejaculation, feelings of control, sexual satisfaction, PE-related distress and subjective impression of improvement. Results. At 6-month posttreatment, all participants showed significant improvements as compared to waiting list condition. The improvements were maintained at 12 month. They were slightly greater in the case of complementary therapist support. Improvements were demonstrated for all forms of PE, but the intervention appeared to be slightly more effective when the problem was of moderate severity. In all cases, improvements in sexual functioning were accompanied by improvements in sexual cognitions. Conclusions. The cost-effectiveness of the self-help manual makes it a valuable first-line treatment for any form of PE. Moreover, the outcome of the bibliotherapy process might be increased by coaching from a health worker specifically trained to this aim. [less ▲]

BACKGROUND: Natural T regulatory cells (Treg) are challenging to expand ex vivo, and this has severely hindered in vivo evaluation of their therapeutic potential. 5-Azacytidine (5-azaC) and Rapamycin (RAPA) are immunosuppressive drugs that promote selectively the expansion of CD4+CD25highFoxp3+ regulatory T cells OBJECTIVE: We investigated whether 5-azaC and RAPA could be used together to promote the ex vivo expansion of Tregs purified from adult human peripheral blood. METHODS: CD4+CD25+ and CD4+CD25- T cells were isolated from PBMC of normal controls using Miltenyi beads and FACS ARIA sorting. These cells subsets were cultured in the presence of anti-CD3/CD28 antibodies and 200 IU/ml of IL2 for 2 weeks. RAPA (100nM) and 5-azaC (1µM) were added to half of the cultures. We monitored cell expansion and after harvest, the cell phenotype, gene expression, T suppression activity and Annexin V binding were determined and compared to values obtained with control cell culture and with freshly-separated CD4+CD25+ and CD4+CD25- T cells. Also we tested the absolute number of Treg in the several culture conditions during the time of expansion. RESULTS: We found that 5-azaC helped maintain FOXP3 expression during the expansion process probably by promoting the conversion of T conventional (Tconv) in Treg, instead Rapa induces selectively apoptosis in Tconv cells and expansion in Treg. Addition of 5-azaC to RAPA treated cultures improved gene expression of FOXP3, CD25, STAT5 and TGF-B resulted in enhanced Treg expansion and suppressive activity. Also Rapa and 5-AzaC combination sustain Bcl-2 protein expression in Treg conferring resistance to apoptosis process. CONCLUSION: 5-azaC may have utility in ex vivo expansion of human Tregs, not as a single agent, but in combination with RAPA. These data may considerably accelerate the development of immunotherapeutic approaches for the treatment of autoimmune disease or posttransplant alloreactions by the adoptive transfer of nTreg cells.

Objectifs En utilisant l'IRM fonctionnelle, nous nous sommes intéressés à l'effet de l'âge sur les substrats neuronaux de l'encodage non réussi – l'activation à l'encodage pour les items oubliés par la suite. Méthodologie Dans un scanner IRM, nous avons soumis des volontaires (20 jeunes et 19 âgés) à une tâche de mémoire épisodique avec consignes d'encodage incident. Durant celle-ci, des dessins d'objets en noir et blanc leur étaient présentés. Il leur était demandé d'effectuer un jugement de taille sur ces objets. Ensuite, toujours dans le scanner, les objets de la phase d'encodage ainsi que de nouveaux objets leurs étaient présentés afin d'évaluer leur reconnaissance de ceux-ci. Pour ce faire, les volontaires effectuaient un jugement de Recollection/Familiarité/Nouveauté. Résultats Les résultats comportementaux montrent une recollection altérée mais une familiarité préservée chez nos volontaires âgés. L'analyse des résultats IRM a été effectuée selon un design évènementiel (SPM8), dans lequel nous avons comparé les aires cérébrales activées à l'encodage pour les items qui n'ont pas été reconnus ultérieurement et pour ceux qui ont donné lieu à un jugement de recollection (p<.001 non-corrigé). Dans les deux groupes, un pattern d'activation correspondant au réseau du mode par défaut (RMD). Chez les volontaires âgés, les résultats ont également mis en évidence une activation supplémentaire du réseau attentionnel fronto-pariétal. Ensuite, le contraste entre les activations pour les items qui n'ont pas été reconnus ultérieurement et ceux qui ont donné lieu à un jugement de familiarité a aussi mis en évidence des régions du RMD, mais dans une moindre mesure. En effet, les activités communes aux deux groupes d'âge n'ont montré qu'une activation du précuneus. Discussion Comparé à la recollection, l'oubli d'informations semble associé, à l'encodage, à un recrutement accru du RMD qui pourrait refléter une incapacité à mettre en place des processus d'encodage efficaces, à la fois chez les jeunes adultes et les adultes plus âgés. De plus, l'activation supplémentaire du réseau fronto-pariétal chez ces derniers pourrait indiquer un fonctionnement moins différencié des réseaux cérébraux associés à l'encodage en mémoire. Lorsque l'on compare l'oubli d'informations à la familiarité, l'activation moindre du RMD pourrait suggérer qu'un certain niveau d'activation du RMD (et donc la présence de pensées étrangères à la tâche) n'empêche pas forcément toute reconnaissance sur base d'un sentiment de familiarité.

School is identified as the main pillar of the fight against sedentariness in youth. Several models of active schools have been described in the literature and, under the umbrella of the school policy enhancing physical activity (PA), five main dimensions can be identified (Physical education, Active transportation, Life environment, Sport at school, PA in the classroom). This underlines that, if the PE teacher is considered as the corner stone of the PA promotion at school, (s)he is not alone to create the conditions aiming to permit to the children to reach the PA level recommended daily. Integrating more PA in the classroom seems to be a promising approach for children lifestyle as well as for their overall learning. Worldwide, initiatives are proposed in order to convince classroom teachers to integrate more often PA in their educational activities. Nowadays, it seems determining to share experiences in order to identify good practices and solutions to the current problems that teachers can encountered on the field. The goal of this presentation is to illustrate two concrete examples of projects implemented in primary schools in Wallonia, Belgium. We will describe the teaching context as well as the main findings provided by a systematic data analysis conducted during these experiments. The first study focused on three classes proposing Brain Breaks (BB) videos during a 10 weeks period. The attitude of the pupils and the teaching staff opinions were analyzed. In the second study, varied PA breaks (BB video, games, and video developed by the pupils) were proposed during periods of two to four weeks. Data from participant observation and questionnaires were used. In both studies, findings support the planning of PA during classroom. Even if more controlled research designs would be necessary in order to determine the evidence of the results, we can state that practitioners and children involved in the projects showed really positive reactions about these opportunities to be more active.

L-glutamic acid is the major excitatory neurotransmitter in the brain. It exerts its effects through metabotropic and ionotropic receptors. Among the latter, three subtypes have been identified: NMDA, AMPA and KA receptors. It is now well established that a deficit in glutamatergic signaling may be responsible for neurological disorders such as mild cognitive impairment, schizophrenia, depression, and ADHD. Enhancement of the signal through positive allosteric modulators of AMPA receptors might be a therapeutic issue for these diseases. These compounds are expected to exert a fine tuning of the signal. Since they require the presence of the endogenous ligand to be active, they are expected to induce less toxicity than agonists. In this context, based on the structure of known allosteric modulators of AMPA receptors such as cyclothiazide and IDRA 21, the Laboratory of Medicinal Chemistry (University of Liège) has developed a series of 1,2,4-benzothiadiazine 1,1-dioxides with high potency as AMPA receptor potentiators. Crystallographic data obtained by the Department of Drug Design and Pharmacology (University of Copenhagen) highlighted those potentiators bind to two contiguous sites at the dimer interface of the ligand binding domain (LBD) of the AMPA receptor1,2. Based on these data, we may expect that the synthesis of dimeric molecules could lead to further improvement in affinity and activity. This assumption was reinforced by docking experiments conducted with virtual examples of dimeric compounds on the GluA2-LBD (collaboration with NAMEDIC). The present work is thus focusing on the preparation of a family of dimeric benzothiadiazine dioxides. Moreover, in collaboration with GIGA-Molecular Pharmacology, we are developing a pharmacological in vitro assay based on the measurement of Ca2+ inflow through a fluorimetric method. This medium-throughput screening will enable the characterization of our new compounds and the validation of our working hypothesis. [less ▲]

The development of comics studies in the United States has been linked to the institutionalization of the ‘graphic novel’ as a ‘literary’ subset of comics deemed worthy of academic attention. Several voices in North-America are now challenging the need for canon formation by arguing for other approaches to the historiography of comics beyond the graphic novel. Histories and definitions, however, as Thierry Smolderen argues, are not only written by scholars, but generated by a multiplicity of social groups actively participating in the ongoing negotiation of what the medium ‘is’. Drawing on these recent trends, I will engage in a disciplinary reflection on the historiography of comics by focusing on authors' histories of the medium. Cartoonists themselves indeed act as comics historians: suffice to think of Jules Feiffer's pioneering The Great Comic Book Heroes (1965). ‘Graphic novelists’ as Chris Ware, Art Spiegelman, Seth or Daniel Clowes have been deeply engaged in recovering the past of comics in their works as well as in essays, reprints, or exhibitions. These histories are fragmentary, emotionally charged and at times anachronistic, but they complicate teleological accounts of the graphic novel, disrupting the academic canon. Confronting this perspective with recent insights in literary historiography, I will attempt to examine some of the specific epistemological issues raised by cartoonists' histories of comics in their divergence or convergence with other historiographic trends such as fanzines and academic research.

Les Pays-Bas catholiques de la première moitié du XVIIe siècle constituent un ensemble politique placés sous la direction d'un gouverneur-général de sang royal ou issu de la haute noblesse hispanique. La cour de ce Prince est organisée sur le modèle madrilène : il est ainsi assisté par un confesseur particulier, choisi par le gouvernement royal pour ses qualités et pour son appartenance à l'un ou l'autre ordre religieux. Les religieux successifs qui occupent la charge font l'objet d'une attention soutenue de la part de différents acteurs politiques : le gouverneur-général lui-même, les courtisans bruxellois, le gouvernement royal, les ordres religieux et la papauté observent avec attention l'action de ces confesseurs. La vision qu'a Rome de ces clercs est celle d'alliés objectifs. Il est entendu que ceux-ci doivent naturellement assister le nonce en toute occasion et contribuer à asseoir la politique romaine en terres habsbourgeoises. Pourtant, à Bruxelles, les principaux intéressés ne suivent pas assidûment cette ligne directrice. Ma communication proposera d'étudier, sur la base de sources issues des Archives générales du Royaume de Belgique et de l'Archivo General de Simancas, l'attitude d'une série de confesseurs princiers actifs dans la grande première moitié du XVIIe siècle face aux attentes de la papauté et de ses représentants dans le but de comprendre dans quelle mesure ce clerc contribua à – ou se tint éloigné de – la politique telle que voulue depuis Rome. Je tâcherai également de recenser et de comprendre les loyautés – à Madrid, à Bruxelles et à Rome – conditionnant l'action de ce religieux. [less ▲]

La légation des Pays-Bas espagnols et de la Franche-Comté près le Saint-Siège au temps de l’agent Laurent du Blioul (1573-1598) n’a jamais véritablement rencontré l’intérêt des historiens. Cela est certainement dû à son manque d’envergure apparent. En effet, elle est, à cette époque, soumise à l’ambassadeur espagnol de Philippe II à Rome et la marge de manœuvre de son agent semble réduite au suivi technique des affaires ecclésiastiques des pays de par-deçà et de par-delà défendues devant la Curie. Une analyse sociopolitique de l’institution permet cependant de nuancer le propos. En dégageant la place que la légation occuperait au sein des puissants réseaux de pouvoir romains de la Monarchie, on constate en effet que celle-ci est loin d’être marginalisée. Au contraire, à travers l’action de son agent, elle est capable d’utiliser mais aussi d’entretenir et d’accroitre l’influence que la royauté exerce sur la ville. Sachant employer efficacement les nombreuses ressources exogènes qu’elle a à sa disposition, l’institution n’apparait alors plus comme le reflet d’une décadence diplomatique des Pays-Bas qui découlerait de l’éclatement et de l’enlisement de la Révolte. Au contraire, elle trouve sa place dans une certaine logique d’incorporation inhérente à la monarchie de Philippe II. Après quelques considérations autour des missions de la légation, cette communication se concentrera avant tout sur le rôle de son agent, Laurent du Blioul. Membre d’une dynastie de gens de robe au service de la maison d’Autriche depuis la fin du XVe siècle, il conserve un souvenir vivace de ces liens, vecteurs de prestige et d’ascension sociale. Nous montrerons en quoi ce service implique des liens d’obligations réciproques entre les du Blioul et leur souverain. [less ▲]

This communication reviews the additive manufacturing activities of the MMS Unit, University of Liège, with a particular focus on the study of post-processing treatments of Al alloy AlSi10Mg. Al alloy AlSi10Mg processed by Laser Beam Melting (LBM) exhibits a much finer microstructure than its cast counterpart due to the ultra-fast cooling rates imposed in the LBM process. One important consequence of this microstructural refinement is that a classical T6 age hardening heat treatment will not have the same effect on LBM AlSi10Mg when compared with cast AlSi10Mg. Indeed, a previous study by the present authors has shown that heat treating LBM AlSi10Mg at 510°C for 6 hours followed by a second isothermal hold at 170°C for 6 hours brought a marked improvement of the yield stress by 30% and of the elongation at break by 220%. However, this was achieved at the expense of a decrease in both hardness and ultimate tensile strength. A better understanding of the underlying phenomena is needed in order to optimize the heat treatment of LBM AlSi10Mg. The present work hence aims at investigating in more depth the mechanical and microstructural evolution induced upon heat treating LBM AlSi10Mg. [less ▲]

La régénération urbaine doit faire face à de nombreux obstacles. Parmi ceux-ci, les plus significatifs sont la réduction des finances publiques ainsi que des obstacles plus structurels comme la captation des plus-values foncières pour financer les infrastructures publiques, la coopération entre le secteur public et privé ou la complexité croissante des projets par l’augmentation des acteurs concernés (commune, région, propriétaires fonciers, promoteurs, développeurs, habitants…). Afin de répondre à ce contexte changeant, de nombreuses villes, notamment américaines, anglaises ou néerlandaises, mettent en place des outils d’auto-organisation (‘Buisness improvement district’, ‘tax increment financing’, …) (van der Krabben et Needham, 2008 ; Meerkerk et al., 2013 ; Peyroux et al., 2012 ; Squires et Lord, 2012)1. Dans cette recherche, nous définissions le terme d’auto-organisation comme : « l’émergence et le développement d’initiatives naissant d’un réseau construit en dehors des institutions gouvernementales ou autres et qui peut se rattacher ultérieurement à ces institutions » (Huygen et al., 2012)2. Quatre caractéristiques centrales distinguent le concept d’auto-organisation d’autres formes de participation : les motivations intrinsèques des acteurs, l’organisation par le biais d’un leadership pertinent, l’autonomie vis-à-vis des institutions et la spontanéité et créativité. Alors que dans certains pays, les outils d’auto-organisations deviennent courants, peu d’exemples sont présents en Wallonie. Pourtant, ils pourraient répondre, en partie, aux problèmes de recyclage urbain mis en évidence (Halleux et al. 2004)3. Par le champ de l’économie comportementale, nous étudierons l’exemple d’un habitat groupé liégeois, les Zurbains. « L’économie comportementale est un champ de l’économie qui se fonde sur le comportement des êtres humains observé dans la réalité et/ou en laboratoire afin d’expliquer les choix économiques des acteurs économiques » (Hanne, 2012)4. Ce courant économique remet en cause le concept l’Homo oeconomicus, la représentation théorique du comportement humain en économie néo-classique. Les Zurbains sont un projet d’habitat groupé sur une vaste friche (8 500 m²) située dans un quartier populaire de Liège, Saint-Léonard. En 2005, vingt-six ménages font l’acquisition de ce terrain dans le but d’y réaliser un ensemble de logements basse énergie. Il faudra attendre 9 ans entre l’achat du terrain et l’installation des premiers habitants. Par l’analyse de trois grandes composantes du comportement économique, nous essayerons de comprendre quels ont été les freins au développement du projet et comment les comportements des acteurs ont influencé la réussite du projet. L’analyse portera sur le partage des risques, la confiance entre les acteurs et l’évolution de coopération (inter et extra groupe). Le projet présente de nombreux intérêts à la fois individuels (logement neuf en centre urbain, économie d’échelle) et collectifs (réhabilitation d’une friche, aide financière régionale pour la commune pour l’aménagement des espaces publics alentours). Cependant son développement a été confronté à de nombreux obstacles : la prise de risque prise due au manque d’expertise dans le montage de projet urbain, une rupture de confiance entre les maîtres d’œuvre et le maître d’ouvrage, une collaboration pas toujours évidente entre le privé (les Zurbains) et le public (la ville ou les gestionnaires des impétrants). Sur base de rencontres avec les acteurs, il s’agira dès lors de dégager les forces et les faiblesses des acteurs wallons dans le développement de projet auto-organisé et d’analyser la potentialité de ce type de projet.

Kinshasa est la capitale de la République Démocratique du Congo et la plus grande ville francophone d’Afrique subsaharienne sur le plan démographique et spatial. Alors que Kinshasa comptait 400 000 habitants en 1960, son volume de population est actuellement estimé entre 8 et 12 millions d’habitants. La forte croissance démographique de cette ville, dont le taux de progression se situerait autour de 4 % depuis 2000, justifie sa dynamique spatiale. La conséquence immédiate est l’étalement urbain et une urbanisation non maitrisée favorisés par l’accroissement de la demande en logement. La crise du logement est de plus en plus forte dans un contexte marqué par une faiblesse des politiques publiques sur l’habitat. La géographie urbaine de Kinshasa connait, en conséquence, de profondes mutations depuis quelques décennies, des quartiers centraux et péricentraux se densifient et des lotissements périurbains colonisent de vastes territoires. Plus spécifiquement la périurbanisation, phénomène d’étalement des villes, s’y impose très largement. La présente communication porte sur notre projet de thèse qui cherche à comprendre les relations entre les mécanismes fonciers et la production de l’urbanisation à Kinshasa. De manière synthétique, la recherche est basée sur l’hypothèse que l’urbanisation de Kinshasa est spatialement inefficace. Elle est de plus en plus éloignée du centre-ville et des axes principaux et colonise vraisemblablement les zones physiquement inappropriées à l’urbanisation. Il ressort de notre revue de la littérature que l’urbanisation de Kinshasa résulte de dynamiques variées. D’un côté, nous assistons à une très forte densification de certains quartiers. D’un autre côté, la ville connaît un étalement urbain qui s’accompagne du développement de quartiers périphériques à faible densité. La première partie de notre travail vise à quantifier le phénomène d’urbanisation à Kinshasa. Cette quantification sera établie sur base des sources statistiques disponibles. Elle mobilisera également les techniques de la télédétection, afin de suivre l’évolution spatiale de la croissance urbaine. Cette partie du travail permettra notamment de vérifier l’hypothèse consistant à considérer que la croissance de Kinshasa oppose et conjugue des dynamiques de forte densification à des dynamiques d’étalement urbain. C’est cette partie du travail qui devra notamment permettre de vérifier si les logiques d’étalement urbain engendrent un gaspillage de ressources foncières préjudiciables aux activités de l’agriculture (péri) urbaine et au maintien du couvert forestier. La seconde partie de notre travail consistera dans le développement d’enquêtes. Des enquêtes seront menées auprès de deux publics cibles : d’une part, les acteurs actifs dans la production urbaine et, d’autre part, les populations. Enquêter auprès des acteurs de la production urbaine (architectes, promoteurs, planificateurs, chefs traditionnels, administrations : urbanisme, habitat et affaires foncières,…) devra permettre une compréhension des mécanismes fonciers et immobiliers qui alimentent la production du logement à Kinshasa (nous pensons en particulier au rôle des prix et des valeurs sur les phénomènes de densification et d’étalement urbain). En parallèle, enquêter auprès des populations visera à évaluer le niveau d’efficacité spatiale de l’urbanisation mise en place. Développer ce sujet de l’efficacité spatiale consistera à vérifier si, d’un côté, la densification n’atteint pas des niveaux critiques et si, d’un autre côté, l’étalement ne conduit pas à des déplacements – et donc à des coûts de transport – inutiles.

Pour atteindre les objectifs énergétiques de l’Union Européenne pour 2050, et plus largement les objectifs fixés à la dernière COP, le secteur de la construction et de l’habitat doit opérer sa mue vers un modèle plus durable. En Belgique, cela passe par la rénovation et l’amélioration des performances du stock bâti existant. La présente étude porte sur l’identification des différents enjeux (environnementaux, économiques et sociaux) liées à la rénovation en Belgique et tente d’objectiver les barrières (de financement, de communication et de réglementation) à une augmentation du taux de rénovation, à travers une revue de littérature des différentes études et projets portant sur ce domaine en Belgique. Ces résultats initiaux devront permettre ultérieurement la conduite des recherches approfondies visant à la modélisation des effets de plusieurs stratégies possibles d’augmentation du taux de rénovation.

Induced anisotropy is a constitutive feature of clays that can be introduced through a proper "Rotational hardening law" allowing the rotation of the yield and the potential plastic surfaces in the stress space. Two rotational hardening laws are studied in this paper. Validation is provided using the results of a drained triaxial test of a Finnish clay. Finite Elements simulations of a circular rigid footing considering an isotropic and anisotropic constitutive laws are presented. The objective is firstly to identify the influence of the isotropy assumption in geotechnical design and secondly to study the effect of different hardening laws on the foundation behavior. [less ▲]

This paper is a part of an ongoing research in the field of sustainable urban densification through providing innovative solutions for zero energy light weight construction. The focus aim of this research is to identify the gaps in the construction solutions for roof stacking, to feed in the innovation pipeline of the European construction landscape in the coming years. This paper presents a comprehensive review of different case studies and efforts in the field of roof raising and its repetition potentials. Based on a structured review, 8 different cases from three different European countries were sorted, placing a variety of methods in comparison with each other. The main contribution of this review lies in the analyses of the existing information in this field and the classification of the different validated methods and approaches that has been used. Finally, despite the existing challenges, it was found that the concept of roof stacking can be widely spread and applied in different contexts. Future research is going to investigate possible solution and to formulate structured scientific approaches to widen its application. [less ▲]

A 10 m thick loess (aeolian silt) layer located beside the Romont quarry (Eben-Emael, Middle Belgium) has been investigated in order to characterize the mechanical behaviour of the silty material. Cone penetration tests (CPT) have been performed with different cones (M1-type, M2-type and electric) in order to evaluate the influence of the cone on the mechanical behaviour interpretation. Concurrently, laboratory tests have been performed on undisturbed samples from core drillings. Laboratory tests consist of a physical characterization (grain size distribution, Atterberg limits) and a mechanical characterization (oedometer tests). This comprehensive investigation study focuses on the comparison of the loess characterization between in situ and laboratory approaches. CPT-based soil behaviour type charts are analyzed and compared with the Unified Soil Classification System. Many relations also exist in the literature between parameters obtained from CPT results and from laboratory tests. The study explores the existing relations between the cone resistance and the oedometer constrained modulus in order to verify the related coefficients proposed in the literature for silty material.

Introduction The diagnostic entity of heboidophrenia has been consigned to oblivion despite its clinical, prognostic, criminogenic value. At the core of this diagnosis lies specifics interactions between psychosis and psychopathy. The diagnosis was first coined by Kalhbaum in 1890, was revived by Anglo-Saxon literature in the first half of the 20th century, and by French psychiatrists in the late 90’. Method We integrated literary sources, clinical experience and an own pilot study as a stepping-stone for a more in-depth research. Cases (n=20) were selected out of samples of Mentally Disordered Offenders in Belgian Medium and High Risk Forensic Facilities. Files, records and therapist’s experiences were quantitatively analysed iteratively to cull subtypes from each other. We here present preliminary qualitative results, more indepth qualitative and quantitative results will be produced. Results The diagnosis subsumes more than a mere DSM-IV-TR Axis I & II comorbidity, it can be seen from a developmental perspective, or from a structural perspective. Both vantage points suggest an interplay between the (paranoid) psychotic process and the antisocial behaviour, where both trigger and induce each other. At this point, we found evidence for three subtypes modes of interplay; 1) mood instability patterns induced either psychopathic or psychotic phenotypic presentation, 2) according to personality organization and its defensive functioning (were psychopathy defends against psychosis), and 3) phenotypic expression of both components (psychopathy and psychosis) linearly co-dependent. Discussion Despite its incremental value, little is known about the therapeutic prospects of this diagnosis. Current results indicate that these patients do question competency to answer for their deeds in a peculiar manner, relapse more often, reoffend more often, do evade treatment opportunities (if they have any), act out more often (in both antisocial and psychotic ways), induce a particular negative counter-transference in psychiatric teams, etc. Because of these particularities and their versatile phenotype presentation, heboidophrenia patients cannot simply be assimilated to the “high risk & high care” population, but need special supervision and clinical insight. In this research, we aim(ed) at discerning semiologic signs in order to support the diagnostic process. [less ▲]

Buildings notably contribute to global environmental negative impacts due to consumption of both embodied energy and natural resources as well as various emissions during their whole life cycle. It is therefore necessary to develop practices to reduce these impacts, mainly by reducing the part of non-renewable resource in material as well as by ensuring the lowest energy consumption possible during their lifetime. New developments in natural fibres and their use in insulating materials can lead to significant improvement in building environmental impact. For this purpose, assessment of environmental performance is needed to support both the design and the production of (new) fibre based insulation solutions. In this context, the Life Cycle in Practice (LCiP) project helps SMEs to reduce the environmental impacts of their products and services across the entire life cycle. Within the frame of this project, Isohemp (BE) hemp concrete block impact is evaluated in a cradle-to-gate LCA. Functional unit is a pallet of hemp concrete blocks ready for shipping. It represents about 1.3 m³ of blocks. Hemp blocks are made by pressing a mix of hemp shives, hydraulic and hydrated limes, and water. Long term carbon storage due to lime carbonation induces a large benefit in Climate Change (CC) category. The balance of the CC indicator for hemp cultivation is also favorable due to carbon dioxide uptake by the photosynthesis occurring during the plant growth. Life Cycle Assessment of hemp concrete blocks ready to ship has also highlights some improvements that can easily be made at the packaging level in order to lower the global environmental impact and increase the sustainability of this insulation material. Data are processed in SimaPro 8 software, with Ecoinvent 3 and ELCD 3 databases, and analyzed with the CML IA method. This method is compliant with the indicators required by EN15804 standard in order to communicate on the environmental performance of Isohemp blocks. [less ▲]

Introduction: from a phenomenological perspective, anorexic female patients seem to experience difficulties regarding the subjective feeling of their own body (embodiment) and their personal identity, which lead to an intersubjectivity impairment within social interactions. Following these findings, this study investigates the “body-for-others” concept (Sartre, 1943) and altruistic hypotheses from the ethologist Albert Demaret (1973) in a sample of anorexic female patients. Two main hypotheses are tested: anorexic patients are expected to define themselves mostly through the gaze of others and as more altruistic than control participants. Method: this study included 67 anorexic female patients (based on the DSM-IV criteria) and 246 control female participants. Three self-reported questionnaires were used: the Eating Disorder Inventory: EDI-II of Garner (French version), the Identity and Eating Disorders questionnaire: IDEA of Stanghellini (French version translated and adapted by us) to assess the “body-for-others” concept and 17 complementary items for the altruistic dimension. Mann-Whitney non-parametric tests were used to compare the two groups. Results: results show that anorexic patients obtain higher scores than the control group for the three questionnaires (p<0,001 for all measurements). Discussion: the IDEA questionnaire enriches the knowledge relative to the body-self relationship and the first-person perspective, which is essential for a phenomenological approach. Furthermore, the promising results concerning the altruistic dimension in anorexia nervosa should be evaluated in future research. Nevertheless, a better validity of the items assessing the altruistic dimension is needed. [less ▲]

Introduction: The Dropout phenomenon has been studied extensively in general psychotherapy and in more specific domains. Therapeutic programs for male batterers across Europe, United States or Canada also have their share of problems in their attempts to maintain users in treatment. The purpose of this study is to identify potential intrapsychic variables associated with dropout and completion of this kind of treatment. Method: Fifty one male offenders enrolled in a group treatment for domestic violence took part in the study (23 who abandoned and 28 who completed). Before the start of therapy, they were surveyed using questionnaires and structured clinical interview to collect sociodemographic data and to assess specific psychological variables, namely emotional distress (BDI), impulsive behavior (BIS-11), early relationship with their parents (PBI), life events (LEDS) and alexithymia (TAS-20), the inability to experience and express subjective emotions. Results: Correlational analysis showed that age, paternal parenting behaviors and the number of significant events reported in the past six months are the only variables correlated with treatment dropout. The younger the participants, the most likely they were to dropout of the group therapy. Moreover, men who completed treatment reported fewer difficulties in their life and less autonomy support by their father than men who prematurely terminated their therapy. Discussion: The present findings pose a serious challenge for all actors involved in specifics treatment programs. Indeed, if all individuals who committed violent acts have the same intrapsychic variables, how do we predict, especially retain and motivate, the users likely to dropout? [less ▲]

Incarceration leads to a break between an individual and one’s social environment, inducing significant losses of identity (Touraut, 2014). Tough delinquent identity remains prominent, during their incarceration, some inmates invest their role of father. Investing his role of father and thus his father’s identity allows the inmate to break away with delinquent’s identity (Tripp, 2009; Walker, 2009). Moreover, research on desistance underlines that turning point like job, marriage or parenthood supports the transition from criminal life to conventional life (Laub et Sampson, 2003; Lebel, Burnett, Maruna & Bushway, 2008). Indeed, becoming parent is a stage in life cycle that can shape one’s lifestyle. From qualitative researches conducted with father inmates since at least 6 months, we have identified the link between investment in parenting and desistance. The hypothesis is that investment in parenting has a positive impact on father’s prison experience, parenting sense of competence and it will support desistance process. A semi-structured interview and several questionnaires assessing relational and social life have been used in this context (WHOQOLbrief, EPS, ESUL, educational attitudes, QAECEP). First results highlight that parenting during incarceration can be difficult. Some inmates try to keep it with visits between inmate fathers and their children. These visits are influenced by different factors and have a positive impact on prison experience. Indeed, with these visits, inmates maintain a link with their children. That is a source of support and hope during incarceration. That allows investment in one father’s identity. [less ▲]

L'un des principaux modèles d'évaluation et d’intervention auprès des jeunes délinquants souligne l'importance d'adapter l'intensité de l’intervention au niveau de risque, de s'assurer que celle-ci cible les facteurs criminogènes et tienne compte de la réceptivité du jeune contrevenant. Il s'agit du modèle RNR, aujourd’hui largement reconnu pour son efficacité dans le domaine de la délinquance juvénile (Andrews, Bonta, & Wormith, 2011). L’évaluation du délinquant basée sur ce modèle améliorerait la justesse des décisions cliniques, permettrait une meilleure classification et identification de profils, proposerait des interventions ciblées ainsi qu’une évaluation efficace des programmes (Andrews & Bonta, 1998). Ce type d’approche est toutefois mis en balance avec le modèle GLM (Fortune, Ward, & Polaschek, 2014) basé sur les forces du jeune et sa responsabilisation. En effet, le modèle RNR peut être compris, dans son extrême, comme contrôlant, cherchant à imposer des normes correspondantes aux dictats de la société, au détriment des intérêts du jeune (Briggs, 2013). Suite à la décision de communautariser la détermination des mesures prises à l’égard des jeunes délinquants en Belgique francophone, notre recherche a pour but d'identifier et de recommander un instrument d'évaluation du jeune à des fins de classification et de gestion de cas en vue d’orienter les mesures ultérieures et interventions. Dans ce contexte, nous présenterons l’outil YLS/CMI 2.0 (Hoge & Andrews, 2011), que nous avons associé à un volet spécifique centré sur l’évaluation des forces du jeune (YCA ; Mackin, Weller, & Tarte, 2004). Nous décrirons le chemin parcouru depuis l’implémentation de l’outil dans les institutions accueillant de jeunes délinquants et nous attarderons sur les intérêts et enjeux de proposer un outil d’évaluation à la croisée des chemins, entre la gestion des risques que le jeune pose et l’importance de considérer ses intérêts et priorités en focalisant sur ses ressources.
