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 ▲]

Set up by the University of Liège, ORBi (Open Repository and Bibliography) knew a lightning increase of the online posted references since its creation in 2008. The official launch took place on November 26th, 2008 and after considerable efforts on behalf of the team which manages the tool, and researchers who introduce themselves their publications, the contents of the repository managed to reach a value of 64245 references among which 38670 with full text. Working for the Library of Geography of the University of Liege, I found interesting to analyze the number of visualizations and downloads of the references (2005 to 2007) posted online by the ULg geographer’s, and the population interested in this literature. The highlight is on WHO and WHERE are the internet users visualizing and downloading ORBi references from? In order to detect the population using this scientific literature, we analyzed the user IP and their distribution in the world. The data was obtained from a MaxMind database. The type of population using this scientific literature: researchers, individuals, public or private companies was also determined. [less ▲]

Hitherto, forty-one national referendums have been conducted on European integration in over twenty countries. While it is clear that this process has not led to a widely shared common identity, this paper explores the hypothesis that national referendums on European issues do in fact contribute to the emergence of a European identity. I will propose three mechanisms by which this is likely to happen. Firstly, although referendums and especially the debate preceding them may sharpen the divide between Europhiles and Euroskeptics, they bear the potential to bring into the public sphere awareness of European issues and therefore to spark a learning process. Secondly, the debates triggered by referendums give rise to the emergence of a European public sphere, even in member-states which do not conduct referendums. Thirdly, they can contribute to narrowing the gap between political elites and ordinary citizens, thereby reducing the democratic deficit. In addition to the burgeoning literature on the topic, which however focuses on the relationship between referendums and support for European integration, Eurobarometers provide substantive and quantitative data on the issues –namely European referendums and identities– raised in this paper. The study will focus on the twenty-seven referendums of the post-Treaty of Maastricht era. The discussion of the concept of European identity opens the essay. In the following sections, I present briefly the political and historical context in regard to referendums upon which I attempt to demonstrate the three specific mechanisms (learning process, European public sphere, and reduction of the democratic deficit) in the emergence of a European identity, using Eurobarometers data which show the evolution of national and European identification before and after the organization of the referendums. The conclusion discusses the findings and explores other elements that matter in constructing a European identity. [less ▲]
