Depuis 2001, les Régions sont compétentes en matière d’organisation et d’élection des pouvoirs locaux. Elles ont adopté des règles différentes. Dans quelle mesure ces règles influencent-elles la négociation d’une majorité politique et la désignation des bourgmestres en Belgique ? Afin de répondre à cette question, des entretiens semi-directifs ont été réalisés avec plusieurs bourgmestres et échevin issus de communes localisées dans les trois Régions. Des différences entre Régions mais également au sein de celles-ci ont été relevées. Les dispositions relatives au mode de désignation du bourgmestre sont primordiales pour comprendre les dynamiques de négociations politiques. Au final, cet article tisse les liens entre les normes juridiques et les jeux des acteurs politiques. [less ▲]

The application of sub-lethal stresses is known to be an efficient strategy to enhance survival of probiotic bacteria during drying processes. In this context, we previously showed that the application of heat stress upon the entry into stationary phase increased significantly the viability of Bifidobacterium bifidum. However, this heat shock has been considered only in small scale bioreactor and no information is available for a possible scaling-up strategy. Five different operating scales (0.2 L, 2 L, 20 L, 200 L and 2000 L) have thus been tested and the results showed that the viability of B. bifidum increases from 3.15 to 6.57 folds, depending on the scale considered. Our observations pointed out the fact that the heat stress procedure is scalable according to the main outcome, i.e. increases in cell viability, but other factors have to be taken into account. Among these factors, dissolved carbon dioxide seems to play a significant role since it explain the differences observed between the test performed at lab-scale and in industrial conditions.

Noise in gene and protein expression is a major cause for bioprocess deviation. However, this phenomenon has been only scarcely considered in real bioprocessing conditions. In this work, a scaling-law derived from a genome-scale studies based on GFP reporter systems has been calibrated to an on-line flow cytometry device, allowing thus to get an insight at the level of promoter activity and associated noise during a whole microbial culture carried out in bioreactor. We show that most of the GFP reporter systems investigated and thus corresponding genes could be included inside the area covered by the scaling-law. The experimental results suggest that this scaling-law could be used to predict the dynamics of promoter activity, as well as the associated noise, in bioprocessing conditions. The knowledge acquired throughout this work could be used for the design of more robust expression systems. [less ▲]

AIMS: The objective assessment of maximal exercise capacity (MEC) using peak oxygen consumption (VO2) measurement may be helpful in the management of asymptomatic aortic stenosis (AS) patients. However, the relationship between left ventricular (LV) function and MEC has been relatively unexplored. We aimed to identify which echocardiographic parameters of LV systolic function can predict MEC in asymptomatic AS. METHODS AND RESULTS: Asymptomatic patients with moderate to severe AS (n = 44, aortic valve area <1.5 cm2, 66 ± 13 years, 75% of men) and preserved LV ejection fraction (LVEF > 50%) were prospectively referred for resting echocardiography and cardiopulmonary exercise test. LV longitudinal strain (LS) of each myocardial segment was measured by speckle tracking echocardiography (STE) from the apical (aLS) 4-, 2-, and 3-chamber views. An average value of the LS of the analysable segments was provided for each myocardial region: basal (bLS), mid (mLS), and aLS. LV circumferential and radial strains were measured from short-axis views. Peak VO2 was 20.1 ± 5.8 mL/kg/min (median 20.7 mL/kg/min; range 7.2-32.3 mL/kg/min). According to the median of peak VO2, patients with reduced MEC were significantly older (P < 0.001) and more frequently females (P = 0.05). There were significant correlations between peak VO2 and age (r = -0.44), LV end-diastolic volume (r = 0.35), LV stroke volume (r = 0.37), indexed stroke volume (r = 0.32), and E/e' ratio (r = -0.37, all P < 0.04). Parameters of AS severity and LVEF did not correlate with peak VO2 (P = NS for all). Among LV deformation parameters, bLS and mLS were significantly associated with peakVO2 (r = 0.43, P = 0.005, and r = 0.32, P = 0.04, respectively). With multivariable analysis, female gender (β = 4.9; P = 0.008) and bLS (β = 0.50; P = 0.03) were the only independent determinants (r2 = 0.423) of peak VO2. CONCLUSION: In asymptomatic AS, impaired LV myocardial longitudinal function determines reduced MEC. Basal LS was the only parameter of LV regional function independently associated with MEC.

Despite a rapid growth and an ongoing need for outplacement services, little is yet known about the perceived adequacy and benefits of these services for redundant employees using them. We surveyed 360 Belgian redundant employees (i.e., clients) using outplacement services provided by a public employment agency. The results indicate that an outplacement experience perceived as adequate for clients fosters their overall impressions of justice towards the dismissing organization; this leads in turn to benefits for them: reduction of negative emotions, enhancement of their perceived well-being, future perspectives, and job-seeking activities - confirming the mediating role of overall justice.

Hydro-Québec has a long interest in on-line Dynamic Security Assessment (DSA) driven by its challenging power network dynamics (angle, frequency and voltage stability, short and long-term dynamics). At the moment, off-line calculated security indicators are combined with an on-line monitoring system to ensure the security of the system. However, new developments in power system dynamic simulation algorithms facilitate real-time or near-real-time DSA calculations and enable on-line transfer limits determination. In this paper, the domain-decomposition-based algorithm implemented in the dynamic simulator RAMSES is presented, along with the techniques used to accelerate both its sequential and parallel execution. RAMSES exploits the localized response of power systems to disturbances and the timescale decomposition of dynamic phenomena to provide sequential acceleration when the simulation is performed on a single processing unit. In addition, when more computational units are available, the parallelization potential of domain-decomposition methods is exploited to provide parallel acceleration. The presented algorithm and techniques are tested on a realistic model of the Hydro-Québec system and the accuracy of dynamic response, the sequential and parallel performances are evaluated. Finally, the real-time capabilities of the simulator are assessed using a shared-memory parallel processing platform. [less ▲]

The Open Access (OA) movement gains more and more momentum with an increasing number of institutions and funders adopting OA mandates for publicly funded research. Consequently, an increasing amount of research output becomes freely available, either from institutional, multi-institutional or thematic repositories or from traditional or newly established journals. Currently, there are more than 2,700 Open Access repositories (Green Open Access) of all kinds listed on OpenDOAR. Scholarly OA repositories contain lots of treasures including rare or otherwise unpublished materials and articles that scholars self-archive, often as part of their institution’s mandate. But it can be hard to discover this material unless users know exactly where to look. Since the very beginning, libraries have played a major role in supporting the OA movement. Next to all services they can provide to support the deposit of research output in the repositories, they can make Open Access materials widely discoverable by their patrons through general search engines (Google, Bing...), specialized search engines (like Google Scholar) and library discovery tools, thus expanding their collection to include materials that they would not necessarily pay for. In this paper, we intend to focus on two aspects regarding Open Access and Primo discovery tool. In early 2013, Ex Libris Group started to add institutional repositories to Primo Central Index (PCI), their mega-aggregation of hundreds of millions of scholarly e-resources (journal articles, e-books, reviews, dissertations, legal documents, reports…). After two years, it may be interesting to take stock of the current situation of PCI regarding Open Access repositories. This paper will analyze their progressive integration into PCI, the numbers of references, the resource types, the countries of origin… On basis of a survey to carry out among the Primo community, the paper will also focus on how libraries using Primo discovery tool integrate Green Open Access contents in their catalog. Two major ways are possible for them. Firstly, they can directly harvest, index and manage any repository ‒their own or any from another institution‒ in their Primo and display those free contents next to the more traditional library collections. Secondly, if they are Primo Central Index subscribers, they can quickly and easily activate any, if not all, of the Open Access repositories contained PCI, making thus the contents of those directly discoverable to their end users.

Dans cette contribution, nous nous penchons sur la possibilité de créer une dynamique interactive entre intervention sur le terrain et recherche scientifique dans le domaine de la formation. Les terrains d’application se situent tous ici dans le domaine de la santé. Nous présentons quatre configurations d’une telle complémentarité. Chacune d’entre elles représente une articulation différente entre le but de développement des participants et celui de production de savoirs scientifiques. Dans le premier cas, une démarche de recherche est entreprise en amont de la conception d’une formation. La deuxième configuration illustre une recherche scientifique appliquée à un dispositif d’intervention existant et qui vient en retour en modifier la logique. Pour la troisième, il s’agit d’une articulation continue entre recherche et formation s’alimentant mutuellement dans une logique de recherche-action. Enfin, la quatrième partie se penche sur trois dispositifs pédagogiques dont la caractéristique est de combiner des intentions formatives avec des préoccupations de recherche [less ▲]

Based on ethnographic research among the ex-Gécamines workers of Panda (Likasi, DR Congo), this article studies the dynamics of the spousal relationship in a post-industrial context that has been long characterized by paternalism. The results of this research suggest that, though men and women living in this mining community talk about their spousal relationships by invoking the ideal of Christian marriage promoted during the colonial period, in practice such relationships faced important changes following Congolese independence in 1960. The nationalization and subsequent dramatic decline of Gécamines caused changes which directly affected three central dimensions of the colonial family model, namely monogamy, the ideal of domesticity, and male authority. If men and women continue to reference this model, it is because, in times of growing poverty, it allows spouses to remind one other of their respective duties as docile housewives and responsible husbands, and to command respect as virtuous Christian families in the local community.

Insults, gossip, and slander are the origin of many conflicts during the Ancien Régime. They are used to hurt someone’s honour or reputation, which are essential values to keeping good relationships in society. People need to defend their honour when they are injured. They can seek reparations by taking legal action or opting for infrajudicial practices, such as contacting a notary. This possibility has attracted too little attention from historians whereas notarial records are a massive source of information related to conflicts affecting people's daily lives. Indeed, during the eighteenth century, inhabitants of Liège contacted a notary in order to find an agreement, clear their name of an insult, or to write their version of an aggression. [less ▲]

The objective of this study was to evaluate the effects of selenium (Se) enrichment of cereals on Belgian Blue bulls performance, on meat quality and chemical composition. Twenty three bulls were used in the present study. Twelve bulls were offered a control diet containing Se at a basal concentration of 58 µg kg-1 of dry matter (DM) and the other 11 bulls given a diet containing 173 µg kg-1DM of Se by means of Se enriched spelt and barley. The Se enrichment of the diet did not affect either the growth performance, the slaughter data or meat quality (p>0.05). There were no effects of Se on tenderness, oxydative rancidity and water losses. However, there were some effects of Se enrichment on the meat chemical composition. The ether extract was decreased from 2.1 to 1.7% DM (p<0.05). There were also significant Se enrichment (p < 0.001) in Longissimus thoracis muscle (177 vs 477 ng g1-DM) and organs: liver (474 vs 1126 ng g1-DM) and kidney (4956 vs 5655 ng g1-DM), Under such condition, the human consumption of a piece of such meat or liver can cover a large part of the recommended daily Se intake estimated between 30 to 57%.
