During the four last decades, Higher Education has tried to re-equilibrate the ratio between the acquisition of knowledge and they development of competencies (being able to act efficiently and ethically in complex situations). Pursuing this objective, in faculties of pharmacy and of medicine, a series of methods – audacious in their time- have been initiated. Three of them are described hereafter. For each of them, we will consider how their field implementation has evolved as well as validity and efficiency issues. The first one is The Problem Based Learning (PBL) approach, in which teaching is replaced by learning, i.e. in which students themselves, after having been motivated by a case presented b y a simulated patient, decide which contents to study and search, in an autonomous way, pieces of information in a huge “Study landscape” full of books and on the internet. In the second strategy, named “Progress Tests”, students have to pass, four times per year, a test on the medical knowledge that should be mastered by a general practitioner. Since during the 6 years of their medical studies he/she passes 24 (not identical but equivalent) tests, each student can observe his/her own progression. The third strategy deals both with training and with evaluation, and, as PBL, relies on role playing. It consists in students spending a few minutes (7 for instance) in various “stations” where they play the role of the professional (a pharmacist, a doctor) facing a concrete situation presented by a simulated patient. These three methods are described on the basis of their concrete implementation in two universities, the Maastricht and the Liège ones. An important common point they share is that they could be implemented thanks to the adoption of a program-referenced approach. This article presents these three educational strategies and the concepts that underpin them. [less ▲]

Diamond is an excellent material for infrared optics and for applications in harsh environments. Some of those desirable properties, i.e. hardness and chemical inertness, also make it a challenging material to machine and etch. In this study we have tested a wide range of etch parameters in an inductively coupled plasma etcher, in order to produce highly controlled, high aspect ratio gratings in diamond. We discuss the effects of pressure, bias power, and some gas mixture variation (pure oxygen and argon-oxygen) on the etch results and how it impacts the etch mask sputtering and redeposition. We also present a method for applying a fresh aluminum mask, in order to etch even deeper optical grating. Gratings with aspect ratios as high as 1:13.5 have been achieved with a 1.42 μm grating period. [less ▲]

Ant mill, caterpillar circle, bat doughnut, amphibian vortex, duck swirl, and fish torus are different names for rotating circular animal formations, where individuals turn around a common center. These “collective vortex behaviors” occur at different group sizes from pairs to several million individuals and have been reported in a large number of organisms, from bacteria to vertebrates, including humans. However, to date, no comprehensive review and synthesis of the literature on vortex behaviors has been conducted. Here, we review the state of the art of the proximate and ultimate causes of vortex behaviors. The ubiquity of this behavioral phenomenon could suggest common causes or fundamental underlying principles across contexts. However, we find that a variety of proximate mechanisms give rise to vortex behaviors. We highlight the potential benefits of collective vortex behaviors to individuals involved in them. For example, in some species, vortices increase feeding efficiency and could give protection against predators. It has also been argued that vortices could improve collective decision making and information transfer. We highlight gaps in our understanding of these ubiquitous behavioral phenomena and discuss future directions for research in vortex studies. [less ▲]

Séverine De Croix et Jessica Penneman présentent un programme de recherche quasi-expérimental et longitudinal qui porte sur l’enseignement de la lecture et de l’écriture de textes informatifs chez des élèves du 1er degré de l’enseignement secondaire en Belgique francophone. Dans cette contribution, elles montrent combien les textes documentaires sont composites et comportent des obstacles liés aux schémas rhétoriques et aux finalités qui les caractérisent. La recherche vise, entre autres, à aider les élèves à construire un texte homogène à partir de données multiples et hétérogènes. Les premiers résultats indiquent que suite au dispositif mis en place, les élèves progressent légèrement dans la manipulation de nombreux documents, relevant de genres variés, et que les enseignants transforment l’outil didactique initial, notamment en sélectionnant les tâches qui sont les plus fermées.

Amongst the dating methods that can contribute to archaeology, it is the technique of stimulated luminescence applied to ceramic materials that is the focus of this paper. The principles and techniques of the method are first explained. In a second part, the reliability of luminescence dating applied to archaeology, and more specifically of building archaeology, is shown via the case study of the early medieval church of Notre-Dame-sous-Terre in the Mont-Saint-Michel, France.

Face à toute situation de violence, la qualification des hostilités représente une étape essentielle : c'est elle qui déclenche, le cas échéant, l'application du droit international humanitaire et définit le régime juridique applicable. Le rôle déterminant de la qualification trouve un écho dans le contexte répressif international et, en particulier, au sein du droit matériel de la Cour pénale internationale (CPI). En effet, l'article 8 du Statut de cette dernière distingue entre les actes constitutifs de crimes de guerre, respectivement, en situations de "conflits armés internationaux" et de "conflits armés ne présentant pas un caractère international". Avec, en filigrane, une injonction à l'intention du juge : déterminer systématiquement la nature des affrontements concernés avant d'envisager les crimes de guerre dont ceux-ci auraient été le théâtre. Dans ce contexte, cette contribution propose un premier bilan de la pratique émergente de la CPI en matière de qualification des conflits. [less ▲]

The glyoxylate cycle is essential for growth on C2 compounds such as acetate. In this investigation, for the first time, we have elucidated the subcellular localization of the enzymes of the glyoxylate cycle in the green microalga Chlamydomonas reinhardtii. Acetyl-CoA synthase and malate dehydrogenase exist as multiple isoforms in this microalga, therefore, we first identified those implicated in the glyoxylate cycle based on the observation that lack of isocitrate lyase (ICL) in a previously identified icl deficient mutantwas correlatedwith specific loss of the other enzymes of the glyoxylate cycle. In this work, we determined that five of the six enzymes associated with the glyoxylate cycle were found to be within peroxisomal microbodies. Citrate synthase, aconitase, malate synthase, malate dehydrogenase, and acetyl-CoA synthase are located in peroxisomal microbodies while isocitrate lyase is cytosolic. Our findings implicate a key role for these cellular compartments in acetate assimilation for Chlamydomonas.Microbodies have only recently been discovered in C. reinhardtii and their existence had been previously debated. The isoform specific subcellular localization determined here suggests that peroxisomal microbodies should be considered in the design of metabolic models for carbon assimilation in C. reinhardtii.

Abstract Background: Migraine is one of the most disabling neurological disorders. The current pharmacological armamentarium is not satisfying for a large proportion of patients because the responder rate does not exceed 50% on average and the most effective drugs often induce intolerable side effects. During recent years, noninvasive central and peripheral neuromodulation methods have been explored for migraine treatment. Overview: A review of the available evidence suggests that noninvasive neuromodulation techniques could be beneficial for migraine patients. The transcranial stimulation methods allow modulating selectively cortical activity and can thus be curtailed to the patient’s pathophysiological profile, while transcutaneous stimulation of pericranial nerves likely modulates central pain control centers. Occipital single-pulse transcranial magnetic stimulation and transcutaneous supraorbital stimulation have the strongest evidence respectively for acute and preventive treatment. Transcranial direct current stimulation and repetitive magnetic stimulation are promising in pilot studies, but large sham-controlled trials are not yet available. Conclusions: The noninvasive neurostimulation methods are promising for migraine treatment and devoid of serious adverse effects allowing their combination with drug therapies. Their application in clinical practice will depend on the industry’s capacity to develop portable and user-friendly devices, and on the scientists’ capacity to prove their efficacy in randomized sham-controlled trials.
