Schools present a privileged environment to address physical inactivity. Actions to promote an active lifestyle have been launched for over 20 years in the European Union. In French-speaking Belgium, such actions have multiplied, but efficiency remains undocumented due to the lack of systematic data regarding health and physical activity (PA) promotion at school. This research aimed to create a tool and to use it to establish an empirical baseline regarding PA promotion in secondary schools. Six main dimensions, all broken into variables, were identified after an extensive literature search. Six experts assigned different weighting factors to each dimension and variable, thereby allowing the attribution of scores. Fifty-one secondary schools were analyzed on this basis. The mean global score of the sample was 44.7 on a maximum of 100. PA was better promoted in urban schools with 250 to 499 students with high socioeconomic status. Real in-school policies aimed at promoting PA were lacking. Active transport to and from school was seldom encouraged. The number of PE classes was insufficient. The facilities used were of better quality than expected. This exploratory research constitutes an important step toward the conception of a tool based solely on objective variables. It should also serve as a catalyst to implement new field projects. [less ▲]

Why is it so difficult to talk about China in a nuanced and contrasting manner without falling back on superlatives and generalisations? In about thirty years, China’s GDP per capita has multiplied by eight. From a marginal economic power during the Maoist period (1949-1978), China is now ranked tenth in terms of global economic weight. “Wealth and power” (fu qiang) is the expression that embodies China’s quest for modernity since the second half of the 19th century, when China was still under the yoke of the West. This ambition is still at the heart of the “Chinese dream of rejuvenation of the Chinese nation” dear to Xi Jinping, which he set out during the Third Plenum of the 18th Central Committee of the Chinese Communist Party. But focusing only on this vision of “wealth and power” takes us back to one of the most common ways of representing China: reducing the ongoing socio-economic changes and dynamics to a set of numeric values, ultimately reified and homogenised. The increased power and internationalisation of the Chinese economy has prompted a combination of worry and enthusiasm. What does this imply about the paradigm shift in the way we portray this country? Perhaps it is still hard to leave behind the image of a subordinate, poor and voiceless China and consider the Chinese people as, at least, our equals. [less ▲]

Context: McCune Albright syndrome (MAS) is a clinical association of endocrine and non-endocrine anomalies caused by post-zygotic mutation of the GNAS1 gene, leading to somatic activation of the stimulatory alpha subunit of G protein (Gsalpha). Important advances have been made recently in describing pathological characteristics of many MAS-affected tissues, particularly pituitary, testicular and adrenal disease. Other rarer disease related features are emerging. Objective: To study pathological and genetic findings of MAS on a tissue-by-tissue basis in classically and non classically affected tissues. Design: A comprehensive autopsy and genetic analysis Setting: Tertiary referral University Hospital Patients: Adult male patient with MAS and severe disease burden including gigantism Intervention(s): Clinical, hormonal and radiographic studies; gross and microscopic pathology analyses, conventional PCR and droplet digital PCR analyses of affected and non affected tissues Main Outcome Measure: Pathological findings, presence of GNAS1 mutations Results: The patient was diagnosed with MAS syndrome at six years of age based on the association of cafe-au-lait spots and radiological signs of polyostotic fibrous dysplasia. Gigantism developed and hyperprolactinemia, hypogonadotropic hypogonadism and hyperparathyroidism were diagnosed throughout adult period. The patient died at the age of 39 from pulmonary embolism. A detailed study revealed mosaiscism for the p.R201C GNAS mutation distributed across many endocrine and non-endocrine tissues. These genetically implicated tissues included rare or previously undescribed disease associations including primary hyperparathyroidism, and hyperplasia of the thymus and endocrine pancreas. Conclusions: This comprehensive pathological study of a single patient highlights the complex clinical profile of MAS and illustrates important advances in understanding the characteristics of somatic GNAS1 related pathology across a wide range of affected organs.

Christophe Bechet explique aux lecteurs le système de défense mis en place autour de Liège et la manière dont les Allemands vont s’en emparer. Il rappelle ainsi fort à propos que le point faible de cette défense est l’intervalle entre les forts. Et que Moltke, le chef d’état-major allemand qui a succédé à Schlieffen, conçoit dès lors l’idée de prendre Liège rapidement, par un coup de main, spéculant sur le fait qu’une fois la ville prise, les forts se rendraient. Mais les forts eux-mêmes ne sont pas exempts de défauts (à dire vrai plutôt nombreux !) sans compter la démoralisation des troupes qui se sentaient prises au piège. L’agonie des forts, que raconte Christophe Bechet par le détail, allait durer jusqu’au 16 août. [less ▲]

This chapter presents ViBe and the underlying ideas of the algorithm. ViBe is an algorithm for the dection of motion by background subtraction. It is a very fast algorithm, based on samples and several innovative processes (time subsampling, random substitution, spatial diffusion, etc). In addtion, we propose a way to measure the computation time by introducing the notion of complexity factor. [less ▲]

This study consists to finalize some technologies for the production of a fermented drink called dèguè. This drink is widely consumed in Benin and other countries in sub-Saharan Africa. Following three different technologies, we had produced three (03) types of dèguè respectively with maize flour, sorghum and millet. These types have been analyzed and their microbiological characteristics were evaluated. The microbiological analysis results obtained from the experiments have shown that lactic acid bacteria, yeasts and molds were the dominant microflora of dèguè and varied respectively 7.22log10UFC/g to 7.55log10UFC/g for lactic acid bacteria and 7.78log10UFC/g to 8.44log10UFC/g for yeasts and molds. Moreover, the statistical analysis of these results showed that there was no significant difference at 5% (p <0.05) between the three types of dèguè. The values of lactic acid bacteria obtained were consistent with the standard (≥ 107/g) attached to the yoghurt. No type contained neither total coliforms nor thermotolerant coliforms. The products (dèguès) were also free of pathogenic microorganisms such as Escherichia coli, Staphylococcus aureus and Salmonella. [less ▲]

In this paper the problem of modal identification of time-varying system is investigated. To do so, a technique based on the sifting process of the Hilbert Vibration Decomposition (HVD) method is presented. The key idea is to estimate the instantaneous frequency of the dominant mode, to extract its corresponding component by demodulation of the recorded signals and then to iterate with the subsequent dominant mode. In the case of multiple recorded signals, a source separation method is used as a preprocessing step to facilitate the identification of the instantaneous frequency for the following demodulation step. To illustrate the method, an experimental set-up consisting in a beam travelled by a non negligible mass is considered. The whole structure is randomly excited during the travel of the mass and some responses on the beam are recorded. [less ▲]

In terms of its eigenvector decomposition, the neutrino mass matrix (in the basis where the charged lepton mass matrix is diagonal) can be understood as originating from a tribimaximal dominant structure with small deviations, as demanded by data. If neutrino masses originate from at least two different mechanisms, referred to as "hybrid neutrino masses", the experimentally observed structure naturally emerges provided one mechanism accounts for the dominant tribimaximal structure while the other is responsible for the deviations. We demonstrate the feasibility of this picture in a fairly model-independent way by using lepton-number-violating effective operators, whose structure we assume becomes dictated by an underlying A4 flavor symmetry. We show that if a second mechanism is at work, the requirement of generating a reactor angle within its experimental range always fixes the solar and atmospheric angles in agreement with data, in contrast to the case where the deviations are induced by next-to-leading order effective operators. We prove this idea is viable by constructing an A4-based ultraviolet completion, where the dominant tribimaximal structure arises from the type-I seesaw while the subleading contribution is determined by either type-II or type-III seesaw driven by a non-trivial A4 singlet (minimal hybrid model). After finding general criteria, we identify all the ZN symmetries capable of producing such A4-based minimal hybrid models. [less ▲]

Cet ouvrage invite le lecteur à un parcours réflexif au moyen de différents exemples et analyse de récents processus de réforme de l’administration publique en Belgique, au Canada et en Suisse afin d’amener progressivement le lecteur à appréhender l’administration non plus seulement comme une " institution ", ce qui implique qu’elle ne soit pas considérée comme universelle, mais comme un produit de l’histoire et de la société. Plus fondamentalement, il invite le lecteur à appréhender l’administration publique comme une " organisation ", c’est-à-dire en prenant en compte l’ensemble des relations formelles et informelles qui y prennent place. Ainsi, l’administration ne serait pas cet ensemble froid d’institutions et de structures chargé de l’exécution des décisions publiques. Bien au contraire, l’administration se révèle, au fil des chapitres, en perpétuelle interaction avec tous les acteurs de l’action publique. Elle apparaît, de la sorte, non plus comme un acteur neutre, objectif, voire passif, mais bel et bien comme un " instrument " participant tout autant que les " citoyens-consommateurs " à la définition de l’action publique. Présentée de cette manière, l’étude de l’administration, de ses mutations et de ses innovations, devient un moyen d’appréhender les transformations actuelles des sociétés occidentales. [less ▲]
