[more ▼]Cette recherche porte sur la traduction, en Belgique, d’une politique européenne de l’emploi – la flexicurité – par différents acteurs institutionnels. À partir d’une analyse documentaire et d’une vingtaine d’entretiens semi-directifs, nous étudierons la manière dont ces acteurs s’approprient et interprètent la flexicurité. Nous nous appuierons principalement sur les apports récents de la sociologie de l’action publique, en particulier l’approche cognitive des politiques publiques (Surel, 2000 ; Muller et Surel, 1998) et l’européanisation des politiques d’emploi (Palier et Surel, 2007 ; 2010). Nous montrerons que cette appropriation a donné lieu, en Belgique, à une transformation du sens conféré à la sécurité, dorénavant assimilée à de la flexibilité.

[more ▼]« Savourer la nourriture et respirer la culture marocaine deviennent une expérience et une émotion unique, à découvrir et à vivre grâce à la combinaison d’arômes, goûts, couleurs, formes et musiques ». Au travers de ce slogan, un renommé restaurant d’inspiration marocaine de la ville de Milan en Italie, invitait ses clients à voyager au travers de leur sensorialité dans une culture alimentaire (et par synecdoque, une culture tout court) autre. Le goût les aurait amenés à expérimenter un exotisme, qui était néanmoins contrôlé, car certaines conditions imposées par les normes locales faisaient en sorte que le déplacement vécu ne fût pas excessivement déstabilisant. Le résultat de ces négociations consistait d’un menu qui accostait les gastronomies marocaine et italienne (ou les procédures de l’une et de l’autre) dans certains plats décrits comme « fusion », qui satisfaisaient (ou non) les exigences des clients. Dans cet article, je vise à mettre en évidence les mécanismes de production discursive et matérielle de ces plats, ainsi comme les opinions des consommateurs. Pour ce faire, j’analyserai le matériel ethnographique collecté auprès du local en question en le comparant avec les pratiques observés dans d’autres restaurants milanais. En ce qui concerne les effets obtenus, j’appuierait mon analyse sur une plateforme de médias sociaux consacrée aux recensions d’endroits et locaux touristiques. La culture alimentaire sera étudiée dans ses aspects symboliques mais aussi matériels, en faisant également recours au matériel visuel récolté.

[more ▼]The impact of pubertal development on the psychological and social functioning of the teenager arouses a particular interest; the most recent research shows the existence of complex relationships between pubertal development and the manifestation of internalized and externalized disorders. Two predominant hypothesis are used for explain influence of pubertal timing on problem behaviors : the maturational deviance theory and the stage termination (early timing) theory. The deviance theory claims that the borderline or abnormal pubertal timing, whether early or late, causes difficulties for adolescent adaptation. The early timing theory suggests that early pubertal timing and the consequent early physical maturation put adolescents at greater risk of adjustment problems because early pubertal maturation interferes with normal progression through the developmental tasks of adolescence. Our study is interested specifically in the links between delinquency during adolescence and pubertal maturation in a population of 141 boys aged between 12 and 18. We measured the pubertal variable starting from the perceived pubertal timing (PPT), which evaluates the teenagers' perception of their pubertal maturation, compared with that of their peers, to understand its impact on various dimensions of the functioning of teenagers: the self-perception (scale of Harter), aggressiveness (scale of Buss and Perry), association with peers and self-reported delinquency (attacks on property and individuals). We began with univariate analyses in order to determine the variables associated with early or late pubertal timing through comparison of scores obtained in those subjects with reference to average maturers. Subsequently, multivariate analyses were used in an attempt to sort out which among the studied factors could be predictor or a determinant of delinquency in relation to pubertal timing. Therefore, stepwise multiple regression analysis was performed. Statistical analyses were run with the SAS software, version 9.1.Our results support the thesis of precocity, the teenagers with an advanced PPT present scores of delinquency and aggressiveness significantly higher than teenagers with a standard PPT. However, the sub-group of teenagers with delayed PPT present raw scores of self-revealed delinquency which are higher than those of teenagers with a standard PPT. These teenagers can be characterized by a significantly higher hostility than the teenagers with a standard PPT. This cognitive dimension of aggressiveness, as evaluated by Buss and Perry, characterizes the functioning of the teenagers with the delayed PPT, who also present poorer self-esteem and dissatisfaction with their physical appearance. On the basis of this assessment, an analysis of multiple regression within each type of PPT aimed at identifying the variables likely to explain the delinquency of teenagers according to their PPT. The results show that the physical factor of aggressiveness is common to the three types of PPT. It is associated with the affiliation with delinquent peers for those teenagers with advanced and normal PPT, whereas for those teenagers with delayed PPT, it interacts with the factor of hostility, which is specific to them. Association with delinquent peers recognized as a major risk factor and predictive for the self-revealed delinquency of teenagers in general does not intervene for these boys who perceive their pubertal development late, compared to the others. The delinquency of teenagers with a delayed PPT cannot be explained by the factors that are considered in the general population, their social functioning and the socialization of these teenagers with delayed puberty is different from that of the other teenagers, as is their implication in delinquency, which is not explained by a kind of socialization with delinquent peers. These results confirm the importance of integrating the puberty variable into research on delinquency, but also at the level of intervention.

[more ▼]In the framework of the Gaia-ESO survey we have determined the fundamental parame- ters of a large number of B-type stars in the Galactic, young ope n cluster NGC 3293. The determination of the stellar parameters is based on medium- resolution spectra obtained with FLAMES/GIRAFFE at ESO-VLT. As a second step, we adopted the acc urate parameters to determine the chemical abundances of these hot stars. We pre sent a comparison of our results with those obtained by the ’VLT-FLAMES survey of massive sta rs’ (Evans et al. 2005). Our study increases the number of objects analysed and provides an extended view of this cluster.

[more ▼]As part of the Gaia-ESO Survey (GES), a number of clusters will be observed that were chosen speci cally for their massive-star content. We report on the procedures we followed to determine the stellar parameters from the massive-star spectra of this survey. We intercompare the results from the di erent techniques used by the nodes of our group to determine these parameters and discuss some of the problems encountered. We present preliminary results for NGC 6705, NGC 3293, and Trumpler 14. We study microturbulence in A-type stars, we use the repeat observation to investigate binarity, and we determine cluster membership from the radial velocity information. The large number of massive-star spectra obtained by the Gaia-ESO Survey will allow us to critically test stellar evolution modelling [less ▲]Detailed reference viewed: 10 (1 ULg) Le cas clinique du mois.

[more ▼]A case of pathological hip fracture associated with an epithelioid hemangioma is reported. Epithelioid hemangioma is a benign tumor, rarely localized in a bone. When the tumor is found on the skeleton, it generally involves a long bone. X-ray does not permit the differenciation of epithelioid hemangioma from other,malignant, vascular tumors. Therefore,the diagnosis requires surgery. Although no consensus treatment guidelines exist, the curettage – filling is most often proposed.

[more ▼]Background/Aims: Heroin-assisted treatment (HAT) can improve the condition of heroin addicts still using street heroin after a methadone treatment. In Belgium, a new trial compared the efficacy of a HAT to existing methadone maintenance treatment. Methods: In this randomised controlled trial, HAT was limited to 12 months. Participants were assessed every 3 months. They were responders if they showed improvement on the level of street heroin use, health or criminal involvement. Results: 74 participants were randomised in the trial. The experimental group (n=36) counted 30% of responders more than the control group (n=38) at each assessment point (p<0.05), except at 12 months where the difference (11%) was no longer significant (p=0.35). Still, after 12 months, participants in the experimental group reported significantly greater improvements (p<0.05) than the control group on the level of street heroin use and on the level of physical and mental health. Both groups reported significantly less criminal facts after 12 months (p<0.001), but with no significant difference between the groups. Conclusions: This trial confirms the short-term efficacy of HAT for severe heroin addicts, who already failed methadone treatment.

[more ▼]In Fair Trade (FT), as well as in other ‘mixed-form’ fields (Becchetti & Huybrechts 2008; Marwell & McInerney 2005), non-profit organizations and social enterprises have been partnering with large corporations over long time periods despite the presence of conditions that might be expected to destabilize such relationships. These conditions include striking differences in size, economic power, and organizational goals or ‘logics’. Given these asymmetries, the collaborations are typically seen as problematic and temporary because the stronger party (the corporation) will impose its (market) logics upon the weaker one (the social enterprise), leading to either instrumentalizing and corrupting the latter or to the breakdown of the collaboration. Whilst some of the literature on FT and other market-oriented social movements has tended to depict corporate participation as a threat to the original goals of the social movement and to the integrity of partnering social enterprises (e.g. Fridell et al. 2008; Reed 2009), there is evidence of a set of social enterprise-corporate relationships that persist over time and cannot be simply summarized as dominated by the sole corporate, market logic. These examples illustrate the emergence of new working relationships across the conventional divides between distinct sectors – the public, private, and civil society – that offer new approaches to managing power asymmetries and apparently conflicting logics – typically, in FT and more generally in social entrepreneurship, market and social justice/welfare logics (Battilana & Lee 2014; Defourny & Nyssens 2006; Huybrechts & Nicholls 2012; Smith et al. forthcoming). This leads to the following research question: Under what conditions can inter-organizational relationships emerge and be sustained despite power asymmetries and the presence of distinct, potentially conflicting, institutional logics? The analysis in this paper aims to extend theory by providing an alternative to more deterministic analyses of inter-organizational relationships that suggest that the more powerful actor will always impose its logics upon the less powerful organization thus undermining the persistence of the relationship over time. In the process, this research adds a new construct to existing theory around the resolution of conflict in institutional logics by suggesting that dynamic persistence is also evident in contrast to examples of conflict resolution through dominance, compromise, hybridization, synthesis, or relationship breakdown. Based on the analysis of the relationships between commercial buyers and FTOs, initially embodying market and social justice logics respectively, this paper proposes a set of key conditions under which dynamic persistence can be observed even in the presence of power asymmetries.

[more ▼]Human biomonitoring (HBM) is an effective tool for assessing actual exposure to chemicals that takes into account all routes of intake. Although hair analysis is considered to be an optimal biomarker for assessing mercury exposure, the lack of harmonization as regards sampling and analytical procedures has often limited the comparison of data at national and international level. The European-funded projects COPHES and DEMOCOPHES developed and tested a harmonized European approach to Human Biomonitoring in response to the European Environment and Health Action Plan. Herein we describe the quality assurance program (QAP) for assessing mercury levels in hair samples from more than 1800 mother–child pairs recruited in 17 European countries. To ensure the comparability of the results, standard operating procedures (SOPs) for sampling and for mercury analysis were drafted and distributed to participating laboratories. Training sessions were organized for field workers and four external quality-assessment exercises (ICI/EQUAS), followed by the corresponding web conferences, were organized between March 2011 and February 2012. ICI/EQUAS used native hair samples at two mercury concentration ranges (0.20–0.71 and 0.80–1.63) per exercise. The results revealed relative standard deviations of 7.87–13.55% and 4.04–11.31% for the low and high mercury concentration ranges, respectively. A total of 16 out of 18 participating laboratories the QAP requirements and were allowed to analyze samples from the DEMOCOPHES pilot study. Web conferences after each ICI/EQUAS revealed this to be a new and effective tool for improving analytical performance and increasing capacity building. The procedure developed and tested in COPHES/DEMOCOPHES would be optimal for application on a global scale as regards implementation of the Minamata Convention on Mercury.

[more ▼]Voice problems can be triggered by both vocal misuse and overuse. While misuse is caused by inappropriate vocal actions, overuse results from greater vocal loading than the individual is able to recover from. Vocal load depends primarily on the quantity of phonation in terms of duration, fundamental frequency and sound pressure of the voice. Portable load quantification systems have been available for several years. These dosimeters allow the objective description of vocal behavior in real situations for a prolonged duration. They are primarily used by voice professionals – people who need their voices for their work – such as teachers and singers. Voice dosimetry makes it possible to identify risky vocal behaviors and situations promoting dysphonia, in an ecological context. The objective of research using these tools is to suggest guidelines for the prevention, evaluation and treatment of dysphonia, mainly in people who use their voices a lot. In addition, this research attempts to set standards for daily voice use for different groups of individuals.

[more ▼]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.

In particular, we show that the exponent we find is optimal. We also analyse the behaviour of~$R_{\alpha,\beta}$ as $\beta$ tends to infinity.
