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. [less ▲]

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.

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. [less ▲]

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. [less ▲]

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 this paper, we study the uniform H\"{o}lder continuity of the generalized Riemann function~$R_{\alpha,\beta}$ (with $\alpha>1$ and $\beta>0$) defined by \[ R_{\alpha,\beta}(x)=\sum_{n=1}^{+\infty}\frac{\sin(\pi n^\beta x)}{n^\alpha},\quad x\in\mathbb{R}, \] using its continuous wavelet transform. 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. [less ▲]

Notre communication a pour objectif de confronter les critères de la personnalité antisociale du DSM-IV et du DSM-5 à une réflexion psychopathologique. Nous commencerons par une analyse des différentes contradictions propres au diagnostic qui nous mèneront à l’identification du critère « primaire » de cette entité qui est l’« incapacité à se conformer aux lois et normes sociales ». Nous confronterons ensuite à des situations cliniques l’hétérogénéité des profils pouvant répondre à ce diagnostic. Nos constats nous conduiront à mettre en doute la validité apparente du concept de personnalité antisociale, puisqu’il recouvre des modes de fonctionnement psychologique variés. La valeur discriminative faible, en matière de fonctionnement psychologique, suggère que c’est une dimension autre que psychopathologique qui organise ce diagnostic. Dénuée de toute attention pour les modes d’interactions, pour le vécu émotionnel et pour les états de subjectivité, la notion de personnalité antisociale ne porte pas d’intérêt à l’individu qu’elle catégorise, mais bien à l’acte délinquant commis par ce dernier. Nous conclurons sur le constat de l’absence de dimension psychopathologique de la personnalité antisociale, qui se révèle être un diagnostic principalement criminologique, à l’inverse des fondements de l’éthique psychopathologique.

À l’heure des politiques d’activation des demandeurs d’emploi et d’un taux de chômage élevé, il semble tout particulièrement intéressant d’interroger les réformes institutionnelles des services publics de l’emploi (SPE), notamment en matière de partenariats. Fin des années 90, la Commission européenne invite les SPE à établir des collaborations avec des organismes d’insertion socioprofessionnelle. Les SPE doivent déléguer une partie de leur mission d’accompagnement des demandeurs d’emploi à des opérateurs privés marchands et non-marchands. Des partenariats publics-privés voient progressivement le jour. Leur objectif est la mise en place de projets de formation et d’accompagnement à destination des demandeurs d’emploi en vue de la réinsertion de ceux-ci dans un emploi stable et de qualité. Perdant leur monopole en matière d’accompagnement, les SPE se repositionnent sur le marché de l’emploi en tant qu’« institution régulatrice » de ce marché. Déléguer leur mission aux opérateurs privés engendre nécessairement la question de la confiance. Comment les SPE accordent-ils leur confiance à ces organismes ? Une étude menée auprès de trois services publics de l’emploi, situés en Belgique et en Suisse, nous a permis d’analyser en profondeur les collaborations entre l’Office de l’Emploi et ses prestataires de service. La recherche porte tout particulièrement sur la construction, la vie et les effets du partenariat en termes de confiance. [less ▲]

The dynamics of the SmallSat, a real-life spacecraft possessing a complex isolation device with multiple nonsmooth nonlinearities is investigated. Experiments show that nonlinearities induce modal interactions between modes with non-commensurate linear frequencies. A model of the structure with a simplified description of the nonlinear connections is first built using techniques available in industry. Numerical continuation is then exploited to compute nonlinear normal modes and uncover interaction phenomena that can jeopardize the structural integrity. [less ▲]

Performance-based aid (PBA) is increasingly advocated as a way to improve development aid effectiveness through resolving incentive issues inherent in aid relationships. Some donors use PBA together with performance-based financing arrangements within partner countries. Expectations from PBA are high – yet, while its rationale may look appealing, it is grounded on a restrictive model and flawed when taking account of real-world context. A number of problems associated to PBA have already been advanced as jeopardising its success. More fundamentally, one may question the mere appropriateness of PBA to provide incentives all along the chain from recipient governments to those who are supposed to produce results. Thus believing that PBA can have a mechanistic trickle-down incentive effect seems an illusion. [less ▲]
