The electrical resistance of a metallic granular packing has been recorded at room temperature. A nearby burster between which sparks are produced, induces a decrease in the resistance of the granular packing as described in the works of Branly. Our measurements emphasize that the decrease is continuous and the resistance variations behave like a stretched exponential law due to the creation of new electrical paths as in nucleation-growth soldering processes. This behavior has been identified to be a diffusionlike process. [less ▲]

A partir de l’examen des différents Plans de Cohésion Sociale (PCS) qui ont vu le jour sous l’impulsion des politiques européennes et ce, dans un contexte de crise de modèle des Etats sociaux européens, cet exposé proposera une approche critique des tentatives actuelles de recomposition des politiques sociales. Ce mouvement puise largement son inspiration dans un projet de participation de tous au sein de la société. Il s’agit désormais d’animer, de faire participer, d’inciter, de produire de l’intégration là où autrefois l’action publique visait prioritairement à protéger, à conférer un statut et une position sociale. Une nouvelle intention publique aurait fait son apparition dans le champ des politiques sociales. Elle viserait davantage à solliciter les individus, à faire appel à leur subjectivité tout en multipliant les lieux d’écoute. Toutefois, pour devenir globalement plus individualisées et subjectives, les politiques sociales ont dû puiser là où précisément des politiques de la subjectivité étaient éprouvées de longue date, à savoir dans les schémas assistanciels de l’aide sociale. On assisterait ainsi à une reconfiguration des frontières du social. Saisi de nouvelles attentes plus singulières et particularistes, il puiserait de plus en plus largement son inspiration aux sources du travail social, se « travaillerait », se mettrait en action par l’intermédiaire d’intervenants rompus aux techniques relationnelles et aux conduites d’entretien [less ▲]

The referees are responsible for the proper progress of sports competitions. However, it is clear that very few studies are devoted to them, particularly with regard to their training. The aim of this study was to analyze the Wallonian situation in five federations: basketball, football, handball, hockey and rugby. We conducted semi-structured interviews with three officials of their refereeing commission. After the analysis of the data, subjects gave a feedback on the synthesis of the interviews (Friedberg, 1994). The SONAL software (v.1.6.11; Alber, 2010) allowed us to process the data. According to our subjects, no federation is genuinely interested by referees, as they prefer to focus more on other aspects ("sport for all", "promotion of their sport", "notoriety of the national team" …). The referee courses are purely theoretical and concluded with an examination (15/15). Then, supervisors follow the referees on the field but the lack of human resources is a real problem (15/15). Only the basketball federation offers learning levels, allowing a gradual advancement. The career-long learning is based on supervisions but also on seminars. The field's experience is the most important factor (15/15) to improve (Pizerra and Laborde, 2011). We noticed also that the football federation implemented refereeing training centers while the basketball federation has established a school of refereeing. In addition, the rugby referee educators must have a certificate of the international refereeing commission while any special skills are requested in the other federations. Except in hockey, all courses are free. In the five federations, the structures are extremely different. An identical framework with different invariable levels, as in coach education (Theunissen, 2007), could facilitate the implementation of interdisciplinary training. [less ▲]

Aujourd’hui, la référence au "développement durable" est utilisée sans vergogne dans la publicité, a toutes les apparences d’une nouvelle vertu et est affichée comme telle dans tous les domaines. Pourtant, l’appellation peut s’avérer inconfortable car elle est contestée à plus d’un titre. Le but de cet article est d’attirer l’attention des animateurs territoriaux sur l’importance de garder une distance critique vis-à-vis de tout slogan aux allures dogmatiques, comme l’est devenu le développement durable. Il présente les limites du modèle classique généralement admis et questionne son utilité comme référence dans le développement et la gestion concertée des espaces publics. [less ▲]

We illustrate a peculiar concept of mirrored reference to address reference tracking control systems for plants subject to impacts. The idea is based on the constructions of artificial references corresponding to suitable reflections of the actual reference performed with respect to the impacting surfaces. We illustrate the application of this idea to reference tracking and state observation for a number of examples of control systems subject to impacts: a one-dimensional hammer hitting a surface, a two-dimensional Newton’s cradle, a two-dimensional mass moving in a planar equilateral triangle and a mass moving in an n-dimensional polyhedral region. For each one of these examples, we provide controllers inducing global exponential stability of the error dynamics. Despite the apparently different nature among the examples, we show that the controller/observer design follows the same paradigm based on mirrored references and we highlight the similarities of the different proofs by showing that they are all based on a specific result about Lyapunov conditions for global exponential stability of hybrid dynamical systems.

To assess various shoulder pathologies / treatments, non pathological populations are often used as references. However, some factors may influence significantly the scapular kinematics within a healthy population and consequently alter the final kinematic evaluation. Results of 3D shoulder assessment found in this study show that small (≈5°) but significant differences exist between gender and between the dominant and non-dominant arms. Therefore the populations used for referential data should be selected carefully. [less ▲]

Among other soil characteristics, those related to the nutrient status and the content in metallic trace elements (MTE) originate from both natural factors and land management. A methodological framework has thus been set up to evaluate the importance of natural driving factors -the so-called pedo-geochemical background- of the spatial distribution of mineral elements in soils and also to compare the current levels of MTE content in agricultural soils with natural values. References for natural, typical, and suspicious values are stated in a Reference Soil System (RSS) which is based on the identification of relationships between geology, relief, and soil, and on the consideration of soil volumes. It integers the land cover and also takes into account the spatial dependance between measurement points in order to estimate the change detection sensibility. Thanks to a comparison-based methodology, to the existence of a detailed soil map, and to the integration of various spatial representation techniques, an image of the state of the soils has been drawn and can serve as a reference for the prediction and the interpretation of point values, for the evaluation of a particular land utilization type, and as a base for the monitoring of soil quality. The reference values about natural and usual content in MTEs for various soil horizons that are proposed reveal especially a relatively weak level of contamination for agricultural soils. [less ▲]

The transmission network plays a key role in an oligopolistic electricity market. In fact, the capacity of a transmission network determines the degree to which the generators in different locations compete with others and could also greatly influence the strategic behaviors of market participants. In such an oligopolistic framework, different agents may have distinct and sometimes opposite interests in urging or hindering certain transmission expansions. Therefore, the regulatory authority, starting from the existing grid, faces the challenge of defining an optimal network upgrade to be used as benchmark for approval or rejection of a given transmission expansion. The aim of this paper is to define the concept of reference transmission network (RTN) from an economic point of view and to provide a tool for the RTN assessment in a deregulated framework where strategic behaviors are likely to appear. A general game-theoretic model for the RTN evaluation is presented, and the solution procedure is discussed. The strategic behavior of market agents in the spot market is modeled according to a Supply Function Equilibrium approach. The impact of transmission capacity expansion on market participants' strategic behavior is studied on a three-bus test network. The RTN is computed and compared with the optimal expansion found when perfect competition among power producers is assumed. [less ▲]
