La société s’interroge sur les actes irrespectueux de certains jeunes et ces derniers demandent du respect. Un paradoxe qui nous amène à donner la parole aux jeunes afin de comprendre le sens qu’ils donnent au respect. D’un point de vue théorique et empirique, le respect se caractérise par sa pluralité de sens (dans la forme et le fond) et se définit souvent par son contraire : l’irrespect. Les deux sont directement liés : agir de manière irrespectueuse peut être un moyen de tenir l’autre en respect. L’irrespect subit par les jeunes nous conduit alors à considérer ces expériences en tant que relation intersubjective au travers de l’identité de l’offenseur et de l’offensé. Perçue comme égalitaire et réciproque, la relation de respect implique dans les discours des jeunes une hiérarchie ; celle ci nous amenant à interroger la notion d’autorité. L’autorité, autrefois inhérente au rapport entre adultes et jeunes, est aujourd’hui tantôt contestée, tantôt perçue comme une nécessité. Dans le contexte d’une société que l’on peut qualifier de fragmentée, la quête de respect nous semble au cœur des constructions identitaires des jeunes et de leur intégration. Les jeunes se trouvent au centre de multiples paradoxes : une liberté restreinte parmi des possibles déterminés, une égalité inaccessible dans la distribution de l’estime et une fraternité remise en cause par la lutte des places. Pour les jeunes, le respect serait le langage de la reconnaissance permettant la mobilité dans l’espace-temps. Une mobilité conditionnée par le fait d’avoir été considéré comme valable dans le regard de l’Autre et donc la possibilité de se percevoir comme respectable. [less ▲]

n this paper we introduce and discuss five guidelines for the use of normative systems in computer science. We adopt a multiagent systems perspective, because norms are used to coordinate, organize, guide, regulate or control interaction among distributed autonomous systems. They are derived from the computer science literature. From the so-called ‘normchange’ definition of the first workshop on normative multiagent systems in 2005 we derive the guidelines to motivate which definition of normative multiagent system is used, to make explicit why norms are a kind of (soft) constraints deserving special analysis, and to explain why and how norms can be changed at runtime. From the so-called ‘mechanism design’ definition of the second workshop on normative multiagent systems in 2007 we derive the guidelines to discuss the use and role of norms as a mechanism in a game-theoretic setting, and to clarify the role of norms in the multiagent system.

We consider the problem of distributed spectrum sensing in cognitive radio networks with a central fusion center, from an energy efficiency viewpoint. In our scheme, each cognitive radio adopts a combination of sleeping and censoring to obtain a sensing result based on energy detection, while the fusion center combines all the sensing results using an OR decision rule. Our goal is to minimize the network energy consumption, given constraints on the global probabilities of detection and false-alarm. We show that the underlying optimization problem can be solved as a convex optimization problem. We then show the energy efficiency of our scheme via simulations using a ZigBee transceiver model.

This paper outlines the sociolinguistic situation in the smallest country of mainland Africa, The Gambia. Very little has been published about the languages and sociolinguistic situation in The Gambia and it was upon discovering this dearth of reliable published sources that led the authors to pool knowledge garnered during independent doctoral research. In this paper we have coupled language shift with a detailed description of the dynamic sociolinguistic profile of The Gambia and trust that it contributes to an understanding of changing ecologies of language in West Africa. Following a portrayal of the indigenous and exogenous languages of The Gambia, with attention to hybrid, overlapping and shifting ethnolinguistic identities, the role of language in several social institutions in a changing society is identified and discussed. The paper culminates in a discussion of linguistic and cultural diversity and appeals for more research in this sociolinguistically unexposed country. [less ▲]

The present work deals with the load bearing and rotational behaviour of composite connections in steel and concrete constructions. For typical buildings, composite connections are assumed to be rigid or pinned. This assumption can lead to uneconomic structures. A design concept for the estimation of the available rotation capacity, the initial stiffness and the moment bearing capacity of semi-rigid connections is presented. On the basis of the plastic hinge theory diagrams were developed to prove the load carrying capacity and the serviceability of composite beams with semi-rigid connections. The presented design model is based on the evaluation of 9 self conducted tests and on the evaluation of 74 tests on composite connections from all over Europe. The availability of the model was proved by intensive nonlinear finite element simulations. [less ▲]
