L’évolution de la société est telle que la sédentarité et le nombre de personnes en surpoids ne font qu’augmenter. En touchant la quasi-totalité des jeunes, l’éducation physique se trouve en première ligne pour agir. Toutefois, le temps hebdomadaire qui lui est imparti et le temps d’activité effectif dans une leçon ne peuvent être suffisants pour exercer un effet décisif sur leur santé. Il peut alors être intéressant que le professeur d’éducation physique endosse un rôle supplémentaire d’éducateur à la santé. Le principe est de faire acquérir les compétences (motrices, techniques, tactiques, etc.) prévues par le programme mais aussi et surtout, d’apporter aux élèves des informations importantes pour leur vie de citoyen, des idées, des astuces, des mises en garde qu’ils pourraient retenir et appliquer au quotidien. Ainsi la physical literacy (l’éducation de l’élève par le mouvement) et l’accountability (le fait d’amener un élément nouveau supplémentaire à l’élève lors de chaque cours) deviennent prioritaires donnant réellement à l’éducation physique l’ambition d’une formation de citoyens physiquement éduqués. Cela nécessite de faire évoluer les pratiques des enseignants et de faire que la dimension santé constitue un fil rouge tout au long de la scolarité des élèves. En effet, les approches liant santé et EPS reposent très souvent sur la motivation extrinsèque des élèves (points, sanction, évaluation certificative…) en contradiction avec l’ambition éducative visant « l’implication spontanée » des jeunes et le concept d’ancrage sociétal qui est actuellement privilégié dans certaines structures de formation. Nous avons donc envisagé un dispositif visant l’acquisition de connaissances théoriques en situation, avant, pendant ou après chaque leçon, au bénéfice de l’implication des élèves. [less ▲]

Biomedical scientific literature is an unexploited treasure. Due to the staggering number of publications it is literally intractable to gather manually all information. Automatized information extraction (IE) is therefore key. An important subtask is the recognition of names in the text as specific entities ( named entity recognition, NER). NER for genes in biomedical literature is a challenging task. This paper reports preliminary results for the identification of gene names in full text with the naive Bayes, support vector machine and the random forest algorithm, showing that there is no loss on performance compared to the gene NER restricted to abstracts.

Following the advent of new Information and Communication Technologies such as smartphones and social networks, the boundaries between what is public and what is private have shifted significantly. While concerns have been expressed by the population regarding the erosion of privacy, as in the case of the Patriot Act or Wikileaks, individuals also deliberately share a lot of personal information online. This has led some thinkers to propose that a “reciprocal transparency”, which would entail a nearly unlimited access to any kind of information for every citizen, might be an alternative to actual privacy laws, which are severely hampered by the pervasiveness of new surveillance technologies. By adopting the approach and the theories of Science and Technology Studies, this research aims at analysing the three cornerstones which underpin the argumentation in favour of transparency. By doing so, it demonstrates that discourses advocating for such transformations rely on the erroneous belief that technology determines social change, on a misconception of privacy, and finally on a utopian vision of transparency. These observations lead to the conclusion that reciprocal transparency is not so much simply a solution to modern ICT-related privacy issues as an ideological view of the world. [less ▲]

Some of the D-amino acids (D-Ser, D-Asp, D-Glu) have gained an increasing attention during the last decades, due to the discovery of their role as neurotransmitters and their implication in different neurological pathologies (Alzheimer’s disease, schizophrenia etc.). Nevertheless, their use as biomarkers is particularly relevant when correlated with the levels of other neurotransmitters. In order to develop a fast and efficient separation method widely accessible for the quantitation of these molecules, we used only common separation tools such as RP-18 stationary phases for reversed phase liquid chromatography (RP-LC) or bare fused capillaries for capillary zone electrophoresis (CZE). For achieving chiral resolution, a derivatization procedure was implemented. (-)-FLEC was the chiral derivatization agent of choice due to its fast and quantitative reaction with primary and secondary amines and the ability of performing in-capillary derivatization. Moreover, the derivatization process implies only a simple mix of the sample and reagent, at room temperature. The separation of the FLEC derivatives of several biologically relevant D- and L- amino acids (Asp, Glu, Ser, Tyr, Trp, Phe, His) together with certain neurotransmitter molecules have been optimized using CZE or RP-LC, chiral resolution being achievable for all amino acids of interest. By the CZE approach the running buffer’s pH turned out to be critical in achieving baseline separation of the targeted analytes. The derivatives of most amino acids could be separated using 60mM acetate buffer at pH 5, while for Asp derivatives the separation could be achieved only at pH 4. Being stronger bases, a third run at a more alkaline pH was needed for the separation of the remainder neurotransmitters. Moreover, the implemented in-capillary derivatization allows a fast and fully automated separation procedure. As for the RP-LC approach 50 mM acetate buffer in combination with an organic modifier (methanol, acetonitrile or tetrahydrofuran (THF)) was tested as mobile phase using gradient elution. Once again, the strong influence of pH on the resolution was observed. The organic modifier nature was of critical importance, where only THF enabled baseline resolution for all amino acid derivatives. [less ▲]

Over the last 40 years, Anguilla species in the northern hemisphere have shown a strong decline in recruitment. Due to a 98% recruitment decline, the European eel is now classified as critically endangered according to the IUCN Red List. To aid conservation and recovery of European eel populations, the European Union recently adopted a Council Regulation which imposes a management system that ensures 40% escapement of the spawning stock biomass, defined as the best estimate of the theoretical escapement rate if the stock were completely free of anthropogenic influences. Various causes likely contribute to the eel decline (e.g. pollution, human-introduced parasites, changes in ocean climate, habitat deterioration…), but habitat fragmentation by migration barriers that prevent the movement of silver eels between freshwater and the sea is probably one of the most important bottlenecks. During the last decades, a substantial number of canals has been developed, creating new habitat for eels. However, eel migration and potential obstacles in these systems are still underexplored. In this study, we tracked 131 European eels (Anguilla anguilla L.) from October 2014 till March 2017 in the Belgian Albert Canal with acoustic telemetry. The 130-km long canal is on average 86 m wide, 5 m deep and functions as a shipping route between the rivers Schelde and Meuse. The canal has a highly regulated water flow and six shipping locks to overcome the 56-m fall, which may have a negative impact on silver eel escapement. Indeed, we found significant delays (i.e. periods with a significantly prolonged residence time) and a ca 50% lower swimming speed near shipping locks compared to riverine conditions. Depending on nothing but their accumulated fat for migration to their spawning grounds, delays can seriously impact eels by wasting precious energy resources needed for a successful trans-Atlantic migration.

Anycast offers a method for making a service IP address available to a routing system from several locations at once. It is used today to provide important services, such as naming and content delivery, in an economic, scalable, and simple to operate manner. The appeal and clear benefits of anycast to service providers have motivated a number of recent experimental studies on its potential performance impact. All studies have, to the best of our knowledge, focused on wired networks, despite the growing dominance of mobile as the most common and sometimes only form of Internet access. In this thesis, we present the first study of anycast performance for mobile users. In particular, our evaluation focuses on three distinct anycast services: K- and F-Root, each providing part the DNS root zone, and Google DNS. Our research revolves around three axes. First, we show that mobile clients are frequently routed to suboptimal replicas in terms of latency and that this issue is not limited to specific regions or ASes of the world. Second, we find that clients are often redirected to a DNS server hosted very far away from her. This happens more frequently while on a cellular connection than on WiFi, with a significant impact on performance. Our study reveals that this is not simply an issue of not having better alternatives, and that the problem is not localised to particular geographic areas or particular ASes. We investigate root causes of this phenomenon and describe three of the major detected classes of anycast anomalies. Third and finally, we explore IP assignment dynamics of mobile clients and find that recurrent IP changes on the client side lead to significant perceived variations of anycast latency. [less ▲]

Roof Stacking represents an approach to accommodate increasing population in the major cities around Europe, new agendas for urban densification emerge in response of finding sustainable solutions to use existing urban infrastructure in the most efficient ways. Several methods for urban densification are being proposed and seen in real life. One of those methods is roof stacking, which is defined as the added structure over the rooftop of an existing building to create one or more stories of living spaces. This report represents the results of conducted investigation on roof stacking method as a sustainable approach for urban densification. The aim of this report is to present a guideline for roof stacking construction approaches and methods and present the learned lessons through interviewing notable architects from different European countries who applied roof stacking. This report identifies the challenges and opportunities when applying roof stacking in addition to proposing recommended solution for the different obstacles that are faced when adding extensions on the rooftops.

We study the influence of external pressure on the electronic and magnetic structure of EuMnO3 from first-principles calculations. We find a pressure-induced insulator– metal transition at which the magnetic order changes from A-type antiferromagnetic to ferromagnetic with a strong interplay with Jahn–Teller distortions. In addition, we find that the non-centrosymmetric E*-type antiferromagnetic order can become nearly degenerate with the ferromagnetic ground state in the high-pressure metallic state. This situation can be exploited to promote a magnetically-driven realization of a non-centrosymmetric (ferroelectric-like) metal. [less ▲]
