This research aims to study the social and economic processes which encourage the spread of mafia practices among some Italian entrepreneurs in the Belgian food sector. My working hypothesis is that mafia practices are violent and predatory strategies to monopolize the economic market, which rely on the use of heterogeneous and cross-class social networks. In this view, these activities of old and new Italian entrepreneurs in Belgium are not the result of the exportation of mafia methods through migratory or cultural ties, but rather the outcome of a complex economic system of production in which certain Italian entrepreneurs have established profitable enterprises in the legal market using violent modalities of accumulation and specific strategies of relation. This research is developed through an ethnographic approach grounded on biographical collection and on participant observation, which is carried out through direct involvement in commercial activities in the sectors of interest.

Through their different encounters with union, court, and government equality agency lawyers, workers report diverse understandings of their personal experience of injustice in the workplace. This paper examines workers’ experiences of discrimination and the role legal professionals play in litigating these issues in Belgium. Bringing together legal and rights consciousness studies and the sociology of intermediation and tracking different stages in the construction of discrimination cases, from the moment when a future litigant describes an event as an injustice to the moment when the judge recognises a discriminatory behaviour (or conversely, dismisses a case), we suggest several possible empirical explanations of the way in which interactions with legal intermediaries affect workers’ rights consciousness. Because we refer to socio-legal studies from common law countries, this paper also calls into question how best to import these studies to assist in analysing legal mobilisations and legal consciousness in continental Europe.

Poly( N -vinylcaprolactam) (PNVCL) is a thermoresponsive and biocompatible polymer that raises an increasing interest in the biomedical area, especially in drug delivery systems (DDS) that include micelles, hydrogels, and hybrid particles. The thermoresponsiveness of PNVCL, used alone or in combination with other stimuli- responsive polymers or particles (pH, magnetic fi eld, or chemicals), is often key in the loading and/or release process in these DDS. The renewed focus on this polymer, which is known for decades, is to a large extent due to recent progress in synthetic strategies. Especially, the advent of efficient controlled radical polymerization (CRP) methods for NVCL monomer gives now access to unprecedented well-defi ned NVCL-based copolymers with unique properties. This Review article addresses up-to-date synthetic aspects, biological features, and biomedical applications of the latest NVCL-containing systems. [less ▲]

Dans un contexte social en mutation prônant l’autonomie de l’individu, le passage à l’âge adulte pour les jeunes en situation de vulnérabilité économique sociale et relationnelle se révèle un véritable défi. L’objectif de l’étude est de comprendre les ressources et les conduites adaptatives de ces jeunes leur permettant de faire face à la souffrance psychique que génère la discontinuité des liens, et d’éviter la désaffiliation sociale et l’errance. Cette recherche clinique de terrain s’inscrit dans une approche ethno-psychologique par sa méthode. Elle s’appuie sur les récits de 6 jeunes adultes âgés entre 19 et 25 ans rencontrés dans le cadre d’un hébergement temporaire en maison d’accueil. Chaque récit est séquencé et analysé selon plusieurs niveaux : les indicateurs sociologiques du passage à l’âge adulte, les modes de relations des individus au niveau familial et social, les indicateurs de précarité. Le parcours de ces jeunes adultes en situation de précarité sociale, cumulant vulnérabilité relationnelle et vulnérabilité économique, les amène à développer des conduites qui leur permettent à la fois de préserver le lien avec autrui, de s’adapter à l’environnement et de préserver une maîtrise d’une affiliation anxiogène. Leur vécu expérientiel de rupture et de perte continue à s’actualiser dans une nécessaire oscillation entre rapprochement et distanciation, en résonnance avec leur style d’attachement primaire. Conclusion « Etablir le lien sur un mode discontinu » apparait comme un mode d’adaptation à l’environnement à la fois protecteur de leur intégrité psychique et fragilisant leur socialisation.

Introduction : L’adolescence est une période tumultueuse caractérisée par des transformations d’ordre physique, psychologique, cognitive et sociale ainsi que par des conduites exploratoires et de recherche de sensations dans lesquelles la consommation de pornographie peut prendre part. L’exposition à la pornographie durant l’adolescence peut s’inscrire dans ce processus développemental avec le risque d’influencer les conduites sexuelles du jeune. Cette thématique peut, dès lors, susciter de nombreuses questions. Méthodologie : Notre recherche, réalisée sur une population d’adolescents âgé entre 15 et 19 ans (N=319), vise à analyser les conduites de consommation de pornographie (motivations, représentations et comportements) en lien avec la recherche de sensations, une dimension prégnante à l’adolescence. Plus particulièrement, nous avons analysé les motivations de ces jeunes à visionner des images et films à caractère pornographique et ce qui les amène à arrêter. Nous nous sommes, également, interrogés quant à l’influence de la consommation pornographique au niveau du développement psycho-sexuel et des pratiques sexuelles de ces jeunes. Pour ce faire, nous avons administré à ces jeunes un questionnaire comprenant, en plus des items se rapportant à la sexualité et la pornographie, plusieurs tests évaluant des dimensions du fonctionnement psychologique et social (test de solitude, recherche de sensation, relations aux pairs, délinquance auto-révélée,... ). Résultats : Nos résultats indiquent qu’une majorité des adolescents ont déjà visionné de la pornographie. L’intérêt pour ce média ainsi que son usage augmente avec l’âge, atteint son apogée vers 16-17 ans puis diminue. Cette tendance curvilinéaire se retrouve également dans les conduites exploratoires telles que les conduites déviantes et la recherche de sensations, ce qui nous amène à envisager une désistance spontanée de la consommation de pornographie en fin d’adolescence. Conclusions : Ces résultats montrent l’importance de comprendre la consommation de pornographie dans un processus développemental et nous amène à envisager une désistance spontanée de cette conduite en fin d’adolescence.

HD76431 is a slow rotating post-HB star that shows an underabundance of helium by 0.5 dex relative to the solar value. These observational facts suggest that atomic diffusion could be active in its atmosphere. We have used the MMT and Bok spectra to estimate the atmospheric parameters of the target star using the model atmospheres and synthetic spectra calculated with TLUSTY and SYNSPEC. The derived values of the effective temperature, surface gravity, helium abundance are consistent with those obtained by Ramspeck et al. (2001b). It appears that NLTE effect are not important for HD76431. We have used Stokes I spectra from ESPaDOnS at CFHT to perform an abundance analysis and a search for observational evidence of vertical stratification of the abundance of certain elements. The results of our abundance analysis are in good agreement with previously published data with respect to average abundances. Our numerical simulations show that carbon and nitrogen reveal signatures of vertical abundance stratification in the atmosphere of HD76431. It appears that the carbon abundance increases toward the deeper atmospheric layers. Nitrogen also shows a similar behaviour, but in deeper atmospheric layers we obtain a significant dispersion for the estimates of its abundance. To our knowledge, this is the first demonstration of vertical abundance stratification of metals in a post-HB star and up to now it is the hottest star to show such stratification features. We also report the detection of two SiIII and one TiIII emission lines in the spectra of HD76431 that were not detected in previous studies. [less ▲]

BACKGROUND: The objectives were to answer the following questions using a well-characterized population in Liege, Belgium: 1) what percentage of abdominal aortic aneurysm (AAA) patients have a positive family history for AAA, 2) what is the prevalence of AAAs among relatives of AAA patients; and 3) do familial and sporadic AAA cases differ in clinical characteristics. METHODS AND RESULTS: Unrelated AAA patients diagnosed at the Cardiovascular Surgery Department, University Hospital of Liege, Belgium, between 1999 and 2012 were invited to the study. A detailed family history was obtained in interviews and recorded using Progeny software. In the initial interview 62 (10%) of the 618 AAA patients reported a positive family history for AAA. We divided the 618 patients into two study groups: Group I: 296 AAA patients (268; 91% males) were followed up with computerized tomography combined with positron emission tomography, and Group II: 322 AAA patients (295; 92% males) whose families were invited to ultrasonography screening. Ultrasonography screening identified 24 new AAAs among 186 relatives (>/= 50 years) of 144 families yielding a prevalence of 13%. The highest prevalence (25%) was found among brothers. By combining the number of AAAs found by ultrasonography screening with those diagnosed previously the observed lifetime prevalence of AAA was estimated to be 32% in brothers. The familial AAA cases were more likely to have a ruptured AAA than the sporadic cases (8% vs. 2.4%; P<0.0001). CONCLUSIONS: The findings confirm previously found high prevalence of AAA among brothers, support genetic contribution to AAA pathogenesis and provide rationale for targeted screening of relatives of AAA patients.

Background. Numerous students are having school difficulties linked to the way they learn. Some people speak of a “metacognitive deficit”. We refer to a “sleeping potential” instead. Be it psychologists, teachers or parents, all wish to develop their skills in order to help these students. This is the case in primary and secondary school. The EDUCA + project is intended to provide possible solutions. Purpose. The aim of this paper is to present a metacognitive and cognitive theory of learning to learn, which will (a) explain why numerous students are having school difficulties, and (b) predict the success of the EDUCA + project.

Ductile damage is a physical phenomena which involves progressive deterioration of mechanical properties of metals, when undergoing high deformations. Compared to plasticity, the physical mechanisms behind damage are more complex and the microscale is not longer negligible. In mathematical damage models, founding an optimal set of material parameters can be a hard task due to the strong coupling and non-linearity of the equations. An identification strategy is then crucial to arrive to a general set of parameters. Therefore, we address the fully characterization of a ferritic steel sheet, involving the elasto-plastic and damage parameters. This poster presents an hybrid experimental-numerical procedure, coupling numerical simulations, optimization algorithms and digital image correlation measurements, over a set of representative experimental and numerical results of tensile, shear and plane strain tests in different material directions. Due to the small thickness of the sheet, the constitutive model is very prone to localization into a shear band difficulting the damage parameters identification. It is found that a porosity induced inhomogeneity plus a mixed hardening can delay localization and represent the entire deformation range of the tests, leading to acceptable results. Different set of parameters are also obtained and then validated with experimental results. This localization phenomena should be carefully considered in applications involving complex strain paths.
