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 ▲]

Referential communication focuses on the reference process which consists in using words in order to describe objects called "referents". The ability of someone to give information regarding what he sees, thinks or feels as well as his ability to understand messages that he hears slowly develops between 6 and 11 years-old in normally developing children. Development of these abilities in Down syndrome children is much more difficult as these children seem to be relatively insensitive to the interlocutor needs in a situation of communication. Our study focuses on the ability oaf Down syndrome children in giving or receiving a correct message. The paradigm we used is the one of Glucksberg et al. (1966). The eight selected Down syndrome children were between 4;10 and 8;5 years-old (the youngest group) and 12;1 and 14;1 (the oldest group). They were matched with a group of normally developing children on the basis of metal age. Different referential communication tasks were proposed as a pre-test. Each child was assessed in the speaker (with another child first and secondly with and adult) and receptor situation (only with another child). At the end of the pre-test, half of the Down syndrome children received training activities of referential communication during 8 weeks. After the training sessions, the children were post-tested. The results show qualitative and quantitative differences between the youngest and the oldest Down syndrome children, on one hand, and between normally developing children and Down syndrome on the other hand. The messages of Down syndrome children are less spontaneous than those of normally developing children, the messages contain fewer information and the responses are more often inadequate. The training seems to have positive effects on Down syndrome children performances, especially on the oldest children. But we notice that the training seems to influence the speaker abilities only. The receptor abilities seems to remain unaffected by the training sessions. Our study gives some information about the area of language the less studied in Down syndrome. However, researches are still necessary in order to complete the intervention perspectives. [less ▲]

Language profile of fragile-X syndrome individuals looks like the one of Down syndrome individuals, except for phonological and pragmatic abilities. If the pragmatic aspect of language is relatively preserve in Down syndrome, it is one of the most impaired language component in fragile-X syndrome. One aspect of the pragmatic component of language remains almost unexplored in this pathology : the common ground management and the organization of the old and the new information in conversation. Sample : 4 fragile-X boys aged from 6 to 12 years-old and 4 typically developing children matched on the lexical age Tasks : 6 referential communication tasks proposed to children both in speaker condition and in listener condition. Tasks were distributed in two groups : 1] building tasks, and 2] combination tasks. Groups of 2 boys work together on referential communication tasks. In simple situations FXS boys can be as efficient speakers and listeners as typically developing children. Difficulties mainly appear when FXS boys have to deal with spatial and ordinal attributes. FXS boys manage less efficiently with an incomplete message especially when it is given by an adult. In FXS syndrome, the efficiency of communication mainly depends of the nature of the items attributes to communicate. Spatial information implies the mastery of vocabulary and concepts which seems to be deficient in several etiologies of mental retardation including FXS boys. Ordinal information implies the manipulation of information that are intrinsically more demanding than nominal dimensions because they are inherently relational. [less ▲]
