Bonjour à tous, et merci aux organisateurs de m’avoir invitée. C’est un plaisir pour moi d’être là aujourd’hui parmi vous. Je vais tout d’abord revenir sur la traduction du « Good Lives Model ». Plusieurs traductions sont communément admises, les plus connues étant celles de « modèle de bonne vie » ou « modèle de vie satisfaisante » ou encore « modèle de vies saines ». Il faut savoir que le groupe Antigone, dans lequel je travaille, n’adhère pas vraiment à ces définitions. En effet, nous trouvons que les traductions françaises proposées enferment le sujet dans une vision prescriptive de ce que devraient être les besoins, qu’elles laissent entendre qu’il y aurait des besoins universels auxquels tous les individus devraient répondre. Or nous ne nous y retrouvons pas et cela ne correspond pas à l’intention de Ward qui veut faire référence à une manière de vivre qui est bénéfique pour le sujet lui-même. Je vous propose donc de garder l’appellation anglophone, « Good Lives Model ». Je vais revenir à l’émergence de ce modèle : il s’agit d’un modèle de réhabilitation qui a vu le jour au début des années 2000 sous l’impulsion de Tony Ward, tout d’abord pour le public des auteurs d’infractions à caractère sexuel. Cependant, il s’est rapidement étendu à d’autres populations, notamment les auteurs de violences domestiques, le public psychiatrique, et ce pour le public aussi bien adolescent qu’adulte. D’autres adaptations ont depuis vu le jour, notamment à l’initiative d’un service français, l’ARCA, qui est spécialisé en recherche et en intervention en délinquance sexuelle, et où le directeur, Erwan Dieu, a adapté le Good Lives Model au public radicalisé. Plusieurs expériences ont également été menées en Belgique, notamment une à l’hôpital des Marronniers, à Tournai, dans une unité de défense sociale qui accueille des délinquants sexuels. L’équipe a décidé, suite à une formation, de reprendre les outils du Good Lives Model et de les adapter avec les patients, afin qu’ils correspondent à leur langage, à leur niveau de compréhension et donc à leurs besoins. Le GLM se veut avant tout humaniste, positiviste et tout à fait écologiste, parce qu’il tient compte des différents systèmes qui gravitent autour de la personne. Il a pour première cible de traitement le développement des besoins humains fondamentaux. Sa deuxième cible est la réduction du risque de récidive, mais qui se veut être un effet de la poursuite du bien-être et des besoins des personnes. Le Good Lives Model comprend des principes théoriques et des implications cliniques. Selon un principe prioritaire au niveau théorique, nous considérons que le délinquant est animé par les mêmes besoins humains que tout un chacun, mais que les voies qu’il emprunte ne sont pas pro-sociales. Nous mettrons donc la notion de besoin au centre de la prise en charge, bien plus que le passage à l’acte délinquant. Le principe clinique qui me paraît être le plus en lien avec le thème qui nous occupe aujourd’hui est peut-être la notion de responsabilité à substituer à celle de culpabilité. Je ne connais pas précisément votre cadre légal protectionnel de la jeunesse. En Belgique, dans les mesures qui sont privilégiées par le magistrat de la jeunesse dès lors qu’un jeune a commis un fait qualifié d’infraction, nous retrouvons les mesures réparatrices, mais dans une visée de responsabilisation du jeune, de prise en compte des conséquences dommageables pour les victimes. Tel est le mandat qui est confié aux équipes chargées du suivi du jeune. Dans le cadre de la philosophie du modèle GLM, nous verrons s’opérer un glissement de la notion de responsabilité, qui reposait avant tout sur les épaules du jeune, vers celles de l’intervenant psychosocial et de son environnement proche : les familiers, mais aussi tous les intervenants gravitant autour du jeune. Par quoi cela passe-t-il concrètement ? Tout d’abord le GLM est attentif à la définition du problème. Bien souvent, le problème est libellé soit dans les rapports qui ont été rédigés par au sujet du jeune, soit dans l’ordonnance qui précise notamment la qualification des faits. Nous laisserons cela de côté, et nous repartirons avec le jeune de la définition du problème tel qu’elle se pose pour lui, dans l’ici et maintenant. Nous ne repartirons donc pas du passé, mais nous nous centrerons sur les conséquences pour lui et pour son environnement dans le présent, ce qui suppose que nous devrons nous accorder sur les buts et objectifs de la prise en charge. Le jeune et les intervenants seront donc associés aux différentes phases du plan de traitement, où les intervenants psychosociaux auront également une responsabilité. Par conséquent, ils s’engageront à réaliser des démarches avec le jeune. Par quoi passe encore cette responsabilité ? L’intervenant psychosocial devra créer les conditions propices à un engagement et à un maintien du jeune dans la prise en charge. La notion de disposition au traitement (Treatment Readiness, Ward et al., 2004) nous éclaire ici sur cette question de l’engagement tant de l’usager que de l’intervenant dans le processus de changement. En effet, la disposition au traitement est définie comme étant « la présence de caractéristiques (états et dispositions) dans le chef du délinquant mais aussi de la situation thérapeutique qui sont susceptibles de promouvoir l’engagement dans la thérapie et donc l’amélioration des aptitudes au changement thérapeutique » (Ward et al., 2004). Il existe également un langage assez particulier qui devra être adapté aux besoins et au niveau de développement du jeune. Tony Ward avait initialement énoncé onze besoins fondamentaux, et le GMAP, qui est le service en Nouvelle-Zélande ayant adapté le GLM pour les adolescents, a réduit le nombre de besoins à huit. Les besoins couvriront surtout la santé (émotionnelle, en général et sexuelle) ainsi que les besoins de réalisation, d’amusement, de trouver un sens à sa vie et de développer des relations. Nous travaillerons donc beaucoup tout ce qui est du registre des émotions, soit tout d’abord pouvoir identifier ses émotions avant de pouvoir les gérer. Dans les questions en lien avec le modèle de réhabilitation, il est vrai que nous travaillons le lien social. Or, dans l’optique GLM, nous ferons d’abord passer le lien social par un lien à restaurer du jeune vis-à-vis de lui-même. Dans l’optique GLM, nous considérerons que travailler le lien social et la réparation d’un dommage vis-à-vis de la société sans se soucier d’abord d’une réparation à l’encontre du jeune est anticipé, par rapport au fait de vouloir d’emblée se lancer dans une logique de réparation. Par conséquent, un accent est mis sur une alliance thérapeutique, et le jeune se sentira beaucoup plus concerné puisque nous partirons de sa définition à lui du problème, telle qu’elle se pose pour lui avant tout. Il pourra alors retrouver un sens, et quelque part, sortir un peu de cette stigmatisation, de cet étiquetage qui lui pèse et qui est souvent lié à tout son parcours, ou qui transparaît au travers des différents rapports, des diverses rencontres avec le magistrat ou les intervenants. Cette optique de travail pourra permettre également au jeune de sortir de ses mécanismes de défense, de faciliter une distanciation par rapport aux mécanismes habituels de minimisation, de déni, d’opposition, et nous verrons que les équipes ou les intervenants qui s’imprègnent de principes liés au GLM pourront s’inscrire davantage dans des rapports relationnels s’éloignant de rapports d’opposition, de recadrage (tels que souvent vécus par les équipes). Pour revenir sur l’expérience menée aux Marronniers, il a été constaté, dans les effets au premier plan, une amélioration de la qualité relationnelle avec les patients. Ceux-ci étaient tout à fait étonnés que l’équipe se détache du travail centré exclusivement sur les passages à l’acte, la récidive, les perspectives de réhabilitation, pour s’intéresser à leurs besoins. Le deuxième effet observé concerne le bien-être des travailleurs, qui s’est traduit par une réduction significative du taux d’absentéisme. L’équipe psycho-sociale ressentant en effet davantage de plaisir à travailler les forces plutôt que les déficits de leurs patients. Avec le jeune, nous travaillons aussi la question de la responsabilité active : toujours dans la notion d’ici et maintenant, que pourra engager le jeune, par exemple si un membre de la famille est toujours très préoccupé, s’il s’agit d’un abus intrafamilial, par la réalité du risque au quotidien ? Que peut dire le jeune de son rapport à la sexualité, mais vraiment dans l’ici et maintenant et dans des perspectives futures, dans ce qu’il peut mettre en place pour rassurer sa famille ? Nous travaillons donc le projet du jeune centré sur ses besoins et son avenir, et beaucoup moins le passé. Cela ne veut pas dire qu’il n’y a pas de place pour le travail sur l’empathie, sur les habilités relationnelles, personnelles et sociales, mais nous nous recentrons d’abord sur le jeune, sur les situations d’adversité qu’il a pu rencontrer durant sa trajectoire de vie afin de favoriser une expression libre de ses émotions. Comme nous l’avons vu avec notre collègue Nadine Lanctôt, bien souvent, nous pointons du doigt tous les éléments de victimisation, maltraitance sexuelle, négligence, mais nous oublions tout l’effet des violences plus émotionnelles, plus insidieuses, qui ont également des effets tout à fait délétères sur le développement du jeune. Ainsi, nous trouvons important de travailler toute cette reconnexion du jeune à ses différents états émotionnels, afin qu’il puisse distinguer le registre des idées, des émotions, des sensations physiologiques, pour ensuite pouvoir refaire ce travail vis-à-vis du passage à l’acte. Le GLM offre un cadre conceptuel et opérationnel utile aux professionnels pour intégrer une gamme d’évaluations et d’informations, de supports théoriques et d’outils d’intervention, dans la perspective d’une compréhension riche, cohérente et complémentaire des (et avec leurs) usagers.

In the last three decades, as a consequence of failures and corporate actions, the number of commercial banks in the United States has shrunk by two thirds. Empirical evidence in the analysis of bank failures suggests the existence of banks which are not susceptible to default. For this reason, we use a semi-parametric proportional hazards cure model with time-varying covariates to study their effects either on the probability that a bank is susceptible to default and on the survival time of failed institutions. We propose a penalized maximum likelihood method for the selection of the most significant variables, using a Smoothly Clipped Absolute Deviation (SCAD) penalty. A simulation study shows that this procedure performs reasonably well. We apply this methodology to a quite large sample of United States commercial banks insured by the Federal Deposit Insurance Corporation (FDIC) and with more than 50 million dollars of total assets during the last quarter of 2002. More in detail, we use bank-specific covariates observed on a quarterly basis until the end of 2015, that we use as proxies for capital adequacy, asset quality, earnings, management efficiency, liquidity, cost structure and size.

Kainate receptors (KARs) consist of a class of ionotropic gluta- mate receptors, which exert diverse pre- and postsynaptic functions through complex signaling regulating the activity of neural circuits. Whereas numerous small-molecule positive allosteric modulators of the ligand-binding domain of (S)-2- amino-3-(3-hydroxy-5-methylisoxazol-4-yl)propanoic acid (AMPA) receptors have been reported, no such ligands are avail- able for KARs. In this study, we investigated the ability of three benzothiadiazine-based modulators to potentiate glutamate-evoked currents at recombinantly expressed KARs. 4-cyclopropyl-7-fluoro-3,4-dihydro-2H-1,2,4-benzothiadiazine 1,1- dioxide (BPAM344) potentiated glutamate-evoked currents of GluK2a 21-fold at the highest concentration tested (200 mM), with an EC50 of 79 mM. BPAM344 markedly decreased desensitization kinetics (from 5.5 to 775 ms), whereas it only had a minor effect on deactivation kinetics. 4-cyclopropyl-7-hydroxy-3,4-dihydro-2H-1,2,4-benzothiadiazine 1,1-dioxide (BPAM521) potentiated the recorded peak current amplitude of GluK2a 12-fold at a concen- tration of 300 mM with an EC50 value of 159 mM, whereas no potentiation of the glutamate-evoked response was observed for 7-chloro-4-(2-fluoroethyl)-3,4-dihydro-2H-1,2,4-benzothiadiazine 1,1-dioxide (BPAM121) at the highest concentration of modulator tested (300 mM). BPAM344 (100 mM) also potentiated the peak current amplitude of KAR subunits GluK3a (59-fold), GluK2a (15- fold), GluK1b (5-fold), as well as the AMPA receptor subunit GluA1i (5-fold). X-ray structures of the three modulators in the GluK1 ligand-binding domain were determined, locating two modulator- binding sites at the GluK1 dimer interface. In conclusion, this study may enable the design of new positive allosteric modulators selective for KARs, which will be of great interest for further investigation of the function of KARs in vivo and may prove useful for pharmacologically controlling the activity of neuronal networks.

Currently, there is a lack of surveys that report the occurrence of gastrointestinal parasites in the white-headed capuchin monkey (Cebus albifrons). We therefore assessed the presence and richness (= number of different parasite genera) of parasites in C. albifrons in wildlife refuges (n = 11) and in a free-ranging group near a human village (n = 15) in the Ecuadorian Amazon. In the 78 samples collected (median of 3 samples per animal), we identified a total of 6 genera of gastrointestinal parasites, representing protozoa, nematodes, acantocephalan and cestodes. We observed a high prevalence (84%) across the 26 individuals, with the most prevalent parasite being Strongyloides sp. (76.9%), followed by Hymenolepis sp. (38.5%) and Prosthenorchis elegans (11.5%). We found Entamoeba histolytica/dispar/moskovskii/nuttalli and Capillaria sp. in only a minority of the animals (3.8%). In addition, we observed unidentified strongyles in approximately one-third of the animals (34.6%). We found a total of 6 parasite genera for the adult age group, which showed higher parasite richness than the subadult age group (5) and the juvenile age group (3). Faecal egg/cyst counts were not significantly different between captive and free-ranging individuals or between sexes or age groups. The free-ranging group had a higher prevalence than the captive group; however, this difference was not significant. The only genus common to captive and free-ranging individuals was Strongyloides sp. The high prevalence of gastrointestinal parasites and the presence of Strongyloides in both populations support results from previous studies in Cebus species. This high prevalence could be related to the high degree of humidity in the region. For the free-ranging group, additional studies are required to gain insights into the differences in parasite prevalence and intensity between age and sex groups. Additionally, our study demonstrated that a serial sampling of each individual increases the test sensitivity. [less ▲]

We study the influence of external pressure on the electronic and magnetic structure of EuMnO3 from first-principles calculations. We find a pressure-induced insulator– metal transition at which the magnetic order changes from A-type antiferromagnetic to ferromagnetic with a strong interplay with Jahn–Teller distortions. In addition, we find that the non-centrosymmetric E*-type antiferromagnetic order can become nearly degenerate with the ferromagnetic ground state in the high-pressure metallic state. This situation can be exploited to promote a magnetically-driven realization of a non-centrosymmetric (ferroelectric-like) metal. [less ▲]

Some of the D-amino acids (D-Ser, D-Asp, D-Glu) have gained an increasing attention during the last decades, due to the discovery of their role as neurotransmitters and their implication in different neurological pathologies (Alzheimer’s disease, schizophrenia etc.). Nevertheless, their use as biomarkers is particularly relevant when correlated with the levels of other neurotransmitters. In order to develop a fast and efficient separation method widely accessible for the quantitation of these molecules, we used only common separation tools such as RP-18 stationary phases for reversed phase liquid chromatography (RP-LC) or bare fused capillaries for capillary zone electrophoresis (CZE). For achieving chiral resolution, a derivatization procedure was implemented. (-)-FLEC was the chiral derivatization agent of choice due to its fast and quantitative reaction with primary and secondary amines and the ability of performing in-capillary derivatization. Moreover, the derivatization process implies only a simple mix of the sample and reagent, at room temperature. The separation of the FLEC derivatives of several biologically relevant D- and L- amino acids (Asp, Glu, Ser, Tyr, Trp, Phe, His) together with certain neurotransmitter molecules have been optimized using CZE or RP-LC, chiral resolution being achievable for all amino acids of interest. By the CZE approach the running buffer’s pH turned out to be critical in achieving baseline separation of the targeted analytes. The derivatives of most amino acids could be separated using 60mM acetate buffer at pH 5, while for Asp derivatives the separation could be achieved only at pH 4. Being stronger bases, a third run at a more alkaline pH was needed for the separation of the remainder neurotransmitters. Moreover, the implemented in-capillary derivatization allows a fast and fully automated separation procedure. As for the RP-LC approach 50 mM acetate buffer in combination with an organic modifier (methanol, acetonitrile or tetrahydrofuran (THF)) was tested as mobile phase using gradient elution. Once again, the strong influence of pH on the resolution was observed. The organic modifier nature was of critical importance, where only THF enabled baseline resolution for all amino acid derivatives. [less ▲]

Cyprinids of the genus Luciobarbus are the most abundant and widespread fishes in most freshwater ecosystems in the Maghreb. In the Mediterranean basin of Morocco, Algeria and Tunisia, all species of Luciobarbus—with exception of L. guercifensis—are superficially very similar and are distinguished mostly by minor morphometric characters. Molecular characters distinguish all species well and nine species are recognised from the area, two of them described here. Luciobarbus chelifensis, from the Chelif River drainage in Algeria, is distinguished by having 41–43+1–2 lateral line scales and a very short anal fin (18–19% SL). Luciobarbus mascarensis, from the Macta River drainage in Algeria, is distinguished by having usually 41+1–2 lateral line scales, a long anal-fin (19–22%) and a short caudal peduncle (15–17% SL). An identification key is given for all African Mediterranean Luciobarbus species except for L. callensis and L. rifensis, which could not be distinguished. [less ▲]

In addition to iconic animals and birds, Antarctica harbours surprisingly diverse microbial communities that drive important biogeochemical processes in virtually all habitats, including ice-free regions, ice sheets and subglacial habitats. Recent studies have shown that Antarctic microbiomes may have unique compositions and functions, exhibit biogeographic patterns, and include endemic taxa that have survived in refugia since the continent started to glaciate. Microbial habitats are under constant pressure due to anthropogenic activities, which may introduce non-indigenous microorganisms, via human bodies, clothing, food, cargo, or construction material. New ‘entry points‘ for microbial contamination are a consequence of the increase and diversification of tourism and research stations. Climatic changes might increase the probability of establishment of non-native taxa. The impacts of such introductions are still unknown, but might lead to a loss of the native microbial biodiversity, or its modification. The technical progress in molecular methodologies has generated very sensitive high-throughput methods. They have the potential to describe the microbial communities with unprecedented detail. However, due to the anthropogenic pressure described above, we may be losing the pristine Antarctic areas that would enable scientists to study the native microbial flora, its functions and properties. One tool of the Protocol on Environmental Protection of the Antarctic Treaty that could be specifically used to protect microbial habitats is the creation of inviolate areas where a special entry permit is required (inside ASPAs, for example) and quarantine equipment needs to be used. These zones could be set aside for future research and become extremely valuable as after a few decades, they would be unique examples of pristine habitats, representative of the native microbial diversity and processes.

The BCCM/ULC public collection is funded by the Belgian Science Policy Office since 2011. A Quality Management System ensures that the services of deposits (both public and safe) and distribution are well documented and efficient for the clients’ satisfaction. It has obtained the ISO 9001 certification for deposition and distribution of strains, as part of the multi-site certification for the BCCM consortium. This collection aims to gather a representative portion of the Antarctic cyanobacterial diversity with different ecological origins (limnetic mats, soil crusts, cryoconites, endoliths…) and make it available for researchers to study the taxonomy, evolution, adaptations to harsh environmental conditions, pigments, and genomic make-up. It presently includes 216 cyanobacterial strains, of which 119 are of Antarctic origin (catalogue: http://bccm.belspo.be/catalogues/ulc-catalogue-search). In addition, cyanobacteria are known to produce a wide range of secondary metabolites (e.g. alkaloids, cyclic and linear peptides, polyketides) with bioactive potential. Genome sequencing of 11 strains has been started to enable genome mining for biosynthetic clusters. Pair-read data from illumina MiSeq runs were obtained and submitted to a bioinformatic pipeline dedicated to the assembly of genomes and search of sequences involved in the biosynthesis of secondary metabolites. Gene cluster prediction analysis allowed to characterize 20 clusters of NRPS, PKS and hybrid NRPS-PKS from 2 to 66kb. Surprisingly, none of the characterized operons had previously been described in the literature. [less ▲]

Chroococcidiopsis is a unicellular cyanobacterial genus that is growing in extreme dry conditions, either in low or high temperatures. At the lower end of the spectrum, they live as cryptoendoliths in rocks of the Mc Murdo Dry Valleys in Antarctica where they were discovered by Imre Friedmann, while at the higher end, they grow as hypoliths/endoliths in hot deserts, e.g. Negev, Gobi, Atacama. The capacity of desert strains of Chroococcidiopsis to stabilize their sub-cellular organization is so efficient that, when dried, they can cope with simulated space and Martian conditionsas well as with high doses of ionizing and UV radiations .

For a long time and due to the socio-economic trauma caused by the closure of the mines, the hazards of abandoned sites and soil pollution, the newness of vestiges, or the symbol of the failure of an industrial development model, on-field industrial remains were not considered as valuable heritage, particularly in rural spaces. Indeed, in the dominant imagery of rural areas, industry and countryside do not fit together (Cloke et al., 1996; Edelblutte & Legrand, 2012). Yet, such industrial activities have a long history in some areas such as in rural East-Belgium. The past deindustrialization resulted in wastelands on which stakeholders have nowadays various interests. Some of these industrial wastelands try to become places of heritage preservation and valorisation (Fagnoni, 2003; Kitchen et al., 2006; Roth, 2007; Mitchell & O’Neill, 2016). In this paper, we consider industrial wastelands with the aim to develop and enhance rural development and heritage landscapes. The mining wastelands are defined as abandoned areas where old traces of mining (e.g. factories and buildings, cuts and fills material, other marks in the landscapes, polluted soils) are still present. These areas are waiting for a new evaluation in order to create rural development strategies and local projects. We study how to preserve and protect these authentic high value landscapes and what can be proposed as type of rural strategy and rural landscape management. How to reallocate the space of wastelands according to the valorisation of cultural and natural heritage? Through qualitative document analysis and stakeholders interviews, we are discussing on the basis of two case studies concerning heavy metals mines in Easten Belgium within an hour’s drive from Liège. The first case is the “Haldes calaminaires” area in Plombières (former lead and zinc mine) and the second one is the “Rouge-Thier” area in Stoumont (former manganese mine), both industrial wastelands in rural area with a real potential for rural development in some touristic, recreational, scientific, and pedagogical frameworks (Rosengarten, 2008; Dussart & Dussart, 1991). Different scenarios are possible to allow both sites to be recognized, saved, protected, enhanced, and developed for tourists and inhabitants, but they must confront the divergent heritage, cultural, biological, urban and socio-economic interests and issues of local and regional actors.

These are the offenses of child sexual abuse, mixed sexual abuse (children and peers), and the rape and offenses with violence that are most likely to be referred to the youth Court. Among the particularly decisive variables associated with the orientations and judicial measures, there were judicial antecedents (sexual or not), problematic behavior at school and multiple fugues. These factors are recognized as risk factors for general delinquency and also appear as determinants in the application of judicial measures for juvenile sex offenders. [less ▲]

Roof Stacking represents an approach to accommodate increasing population in the major cities around Europe, new agendas for urban densification emerge in response of finding sustainable solutions to use existing urban infrastructure in the most efficient ways. Several methods for urban densification are being proposed and seen in real life. One of those methods is roof stacking, which is defined as the added structure over the rooftop of an existing building to create one or more stories of living spaces. This report represents the results of conducted investigation on roof stacking method as a sustainable approach for urban densification. The aim of this report is to present a guideline for roof stacking construction approaches and methods and present the learned lessons through interviewing notable architects from different European countries who applied roof stacking. This report identifies the challenges and opportunities when applying roof stacking in addition to proposing recommended solution for the different obstacles that are faced when adding extensions on the rooftops.
