[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.

[more ▼]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.

A partir de l’analyse de récits d’expériences marquantes, à forte charge émotionnelle, rapportées par des enseignants débutants, des schémas d’intelligibilité de ces situations vécues ont été construits. Ceux-ci rendent compte des transformations identitaires et émotionnelles des enseignants débutants au travers des dynamiques transactionnelles de reconnaissance. Ces résultats ouvrent des perspectives pour la formation initiale des enseignants et l’accompagnement des enseignants débutants. Les schémas d’intelligibilité pourront être utilisés dans une démarche de réflexivité pour faciliter le décodage de situations professionnelles à forte charge émotionnelle vécues par l’enseignant et l’aider à donner sens à ses expériences [less ▲]Detailed reference viewed: 12 (2 ULg) Trifles for 'Unflemings'.

[more ▼]BACKGROUND: Given the limited availability of healthcare resources and the recent introduction of new anti-osteoporosis drugs, the interest in the cost effectiveness of drugs in postmenopausal osteoporosis remains and even increases. OBJECTIVE: This study aims to identify all recent economic evaluations on drugs for postmenopausal osteoporosis, to critically appraise the reporting quality, and to summarize the results. METHODS: A literature search using Medline, the National Health Service Economic Evaluation database and the Cost-Effectiveness Analysis Registry was undertaken to identify original articles published between January 1, 2008 and December 31, 2013. Studies that assessed cost effectiveness of drugs in postmenopausal osteoporosis were included. The Consolidated Health Economic Evaluation Reporting Standards (CHEERS) statement was used to assess the quality of reporting of these articles. RESULTS: Of 1,794 articles identified, 39 studies fulfilled the inclusion criteria. They were conducted in 14 different countries and nine active interventions were assessed. When compared with no treatment, active osteoporotic drugs were generally cost effective in postmenopausal women aged over 60-65 years with low bone mass, especially those with prior vertebral fractures. Key drivers of cost effectiveness included individual fracture risk, medication adherence, selected comparators and country-specific analyses. Quality of reporting varied between studies with an average score of 17.9 out of 24 (range 7-21.5). CONCLUSION: This review found a substantial number of published cost-effectiveness analyses of drugs in osteoporosis in the last 6 years. Results and critical appraisal of these articles can help decision makers when prioritizing health interventions and can inform the development of future economic evaluations.

[more ▼]The stay cables on cable-stayed bridges have been the subject of considerable research in order to understand the origins of the dry galloping phenomenon. Surface irregularity is one of the last parameters that have not been thoroughly examined. This paper focuses on static wind tunnel tests on original High Density Polyethylene cable covers in a range of Reynolds numbers from the sub-critical regime to the critical, corresponding to values ranging from Re = 9.6x104 to Re = 3.3x105. The experiment consists in testing cable covers of various diameters in order to investigate the effect of surface irregularity (roughness and circularity defect) on the mechanism of dry galloping excitation. Previous studies reported that dry galloping is caused by the appearance of a negative pressure bubble on one side of the circular cylinder at the critical Reynolds number range, leading to a rapid drop in the drag coefficient and the appearance of a non-negligible lift force. The results of the present investigation demonstrate that there is a clear correlation between the single bubble pressure pattern and the circularity defect along the tube. They further show that surface roughness has little effect on the location of the bubble. The paper also treats the spatial and temporal correlation of the instantaneous pressure pattern along the tube with respect to the circularity defect.

Dans les pages suivantes, je suggère qu’Ehrenfels et Meinong ont apporté certaines améliorations substantielles à la position de Brentano. Ces améliorations résident essentiellement dans les deux points suivants : (1) les volitions se caractérisent par une dimension « active » ou conative qui fait défaut aux sentiments, ce qui interdit de les ranger dans une seule et même « classe » de phénomènes psychiques ; (2) le concept de valeur trouve son origine empirique dans les volitions ou les phénomènes conatifs, non dans les sentiments ou phénomènes affectifs.
