La « Grande Récession de 2008 » a un mérite. Un seul ! Elle a rendu public le fait que personne ne savait exactement ce qui s’était passé, ni ce qui se passait. Pourquoi une telle crise de confiance avait-elle vu le jour ? Quelles en seraient les conséquences ? Toutes et tous se sont trompés, y compris les meilleurs. Même celles et ceux qui étaient convaincus d’avoir raison ! Plus que jamais, l’incertitude, la saine et souveraine incertitude, garantit la liberté de l’investisseur... et du professeur ! [less ▲]

À travers cette recherche, les auteurs visent à mettre en évidence, chez les étudiants, les apports réels, en termes d’apprentissages et de développement professionnel, de situations d’enseignement intégrant une technologie, à savoir les tablettes numériques. Le groupe d’étude se constitue d’un enseignant en histoire en haute école pédagogique et de trois classes d’étudiants en formation pour devenir enseignants. Ce groupe fera l’objet d’une analyse approfondie au travers d’observations filmées, examinées à l’aide de grilles, et de commentaires réflexifs (de l’enseignant et des étudiants) issus d’entretiens d’autoconfrontation sur divers extraits des situations d’enseignement menées et vécues. Cette méthodologie conduira à croiser plusieurs types d’informations : (1) les objectifs de l’enseignant au moment de préparer la situation d’enseignement, (2) sa perception des apports mis en place à travers la technologie, (3) la perception de ses étudiants et (4) les observations des auteurs. Soucieux de contribuer à l’analyse réflexive sur l’intérêt d’intégrer le numérique en éducation, les auteurs veulent mettre en évidence les apports réels de l’activité, les points de passage obligés et les principales difficultés de sa mise en place. Ces résultats pourront éclairer les enseignants souhaitant se lancer dans ce genre d’activité innovante. [less ▲]

Over the last couple of years, Beninese magistrates have been on strike for months in a row. In 2012, it was about the Ministry of justice implying corruption issues. In 2013, it was about independence and fear of political infringement. In 2014, it was about the most recent appointments. When it comes to judges from the bench, most of them complain about their substantial workload, low pay and poor working conditions. They also highlight the discrepancies between the magistrate’s social status and what their families expect from them, the standards of living that people assume that they have. In short, there seems to be a professional malaise within the Beninese bench, who feel like the state is letting them down, yet judges also insist on the importance of their work, and of doing it right. This is why, for the purpose of this paper, we will be looking at the discourses and representations of Beninese judges on their own social and professional status. What does it mean to be a judge in Benin today? Why do young lawyers choose that professional path over other legal careers? How do they ‘do their job right’ and what are the obstacles to it? Considering both age and gender, we are also trying to look at what it means to be a civil servant today, when the state is no longer the only – or the most promising – employer for legal practitioners.

This work, for the first time, investigates the characteristics of different output metrics for a three degree-of-freedom (DoF) coupled resonator sensor. The main aspects examined are sensitivity and linear range. It is shown from electrical measurements that using the vibration amplitude ratio as an output signal provides improved sensitivity and linearity range, compared to other methods such as shift in eigenstate, mode frequency or amplitude difference.

Starches isolated from white and pigmented sorghum (Sorghum bicolor (L.) Moench) were used to determine enzymatic activity of starch hydrolysis by fungal (Aspergillus Oryzae) and bacterial (Bacillus Subtilis) α-amylase and oligosaccharides profiles of hydrolysate was determinate in same conditions by High Performance Exchange Anion Chromatography with Pulsed Amperometric Detection (HPEAC-PAD). Pure starches from potato, amylose and amylopectin were used for comparison. Oligosaccharide compositions ranging from glucose (DP1) to maloheptaose (DP7) as well as the significantly effect of α-amylase source and starch structure were determined. [less ▲]

The present study looks at the efficacy of 3 types of written corrective feedback on errors made by French-Speaking High School students writing in English. More than 100 students, taught by 5 different teachers in 3 different schools, participated in the study. Each participant was randomly assigned to a different type of written corrective feedback: underlining, direct correct or explanation. Each time the students wrote a text in their EFL class, I (the researcher) corrected it, selected 10 errors and asked the students to state whether they understood the error. If they understood the error, they were asked to correct and/or explain it, depending on their treatment group. I then analyzed the corpus of more than 2000 errors: all the errors were categorized and the uptake moves (students’ corrections and explanations) verified. Finally, I checked whether there was a positive correlation between error types, types of corrective feedback, and students’ uptake. [less ▲]

Using quasar polarizations and a sample of large quasar groups drawn from the SDSS DR7, we showed that at HIGH REDSHIFTS (z ~ 1.5) the spin axis orientations of black holes are correlated to the major axes of the groups to which they belong. Inside very rich groups the BH spins are aligned with the major axes. When the richness decreases, the spin axes become preferentially perpendicular. [less ▲]

The Becco locality (Liège province), belongs to the Theux tectonic window and represents a proximal, probably fluvial, environment corresponding to a channel infill. We present here a preliminary report of the fossil assemblage discovered at the locality. The Becco site has yielded a diverse flora of early seed plants including Moresnetia zalesskyi, Dorinnotheca streeli and Condrusia sp. This assemblage, characteristic of the Belgian Famennian, highlights the diversity of early spermatophytes in the country. Becco has also delivered a rich vertebrate fauna with antiarch, groenlandaspid and phyllolepid placoderms, diplacanthiform acanthodians, as well as actinopterygians and various sarcopterygians. The fossiliferous assemblage of Becco resembles those of several Devonian tetrapod- bearing localities, including that of Strud in Belgium, and could therefore provide a favorable palaeoecological setting in the search for early tetrapods.

“Urban biorefining” is an original concept aiming at using urban wastes (household wastes, municipal wastes, industrial liquid and/or solid residues and side-products, etc.), mainly of vegetal origin, for the production of an array of biofuels and bioproducts. This “urban biorefining” concept fits particularly with the economic, geographic and politic contexts and constraints of the Walloon Region (south part of Belgium). Indeed, Walloon Region is a very small territory (area of about 6,504 sq mi) with a temperate climate. Supply feedstock, mainly arising form forestry and agriculture, are thus rather restricted, submitted to importation, and subjected to non-standardized quality. Several examples of our regional strategy, still available on an industrial scale, are herein proposed and detailed. [less ▲]

The flight of barnacle geese at airspeeds representing high-speed migrating flight is investigated using experiments and simulations. The experimental part of the work involved the filming of three barnacle geese (Branta Leucopsis) flying at different airspeeds in a wind tunnel. The video footage was analysed in order to extract the wing kinematics. Additional information, such as wing geometry and camber was obtained from a 3D scan of a dried wing. An unsteady vortex lattice method was used to simulate the aerodynamics of the measured flapping motion. The simulations were used in order to successfully reproduce the measured body motion and thus obtain estimates of the aerodynamic forces acting on the wings. It was found that the mean of the wing pitch angle variation with time has the most significant effect on lift while the difference in the durations of the upstroke and downstroke has the major effect on thrust. The power consumed by the aerodynamic forces was also estimated; it was found that increases in aerodynamic power correspond very closely to climbing motion and vice versa. Root-mean-square values of the power range from 100 W to 240 W. Finally, it was observed that tandem flying can be very expensive for the trailing bird. [less ▲]
