Le souci de présenter une image harmonieuse et attrayante du territoire impose toutefois une régulation de plus en plus rigoureuse des expressions culturelles qui s?incarnent dans ces manifestations. À travers une comparaison de deux grands festivals (multi-)culturels urbains, le carnaval de Notting Hill et le Défilé de la Biennale de la Danse de Lyon, analysés l?un et l?autre pour la première fois de façon approfondie dans le cadre d?une enquête de terrain étalée sur près de 5 ans, ce livre entend comprendre les facteurs qui ont présidé à la transformation de certains mouvements culturels urbains comme le hip-hop ou les Sound systems en ressources pour le développement économique local. Mobilisées au service des politiques urbaines, célébrées dans le cadre de fêtes spectaculaires, ces expressions culturelles sont progressivement soumises aux critiques du champ artistique, en même temps que l?artiste professionnel est appelé à devenir un « modèle » susceptible de contribuer à la « modernisation » des cultures minoritaires, à leur « ouverture » et leur « connection » à d?autres univers culturels. Un processus jugé indispensable à l?insertion des minorités ethniques dans les logiques de développement privilégiées par les nouvelles élites urbaines. De ce point de vue, le principal intérêt de cette recherche est de montrer que si la promotion de ces carnavals et autres défilés participe bien d?un (re-)modelage des expressions culturelles minoritaires, ces politiques vont bien au-delà de la simple mise en scène d?une ville créative et cosmopolite : elles affectent directement les manières d?être et de faire ensemble dans le sens d?une « mise au travail » des potentialités culturelles des? 606 $aUrban Studies 606 $aHistory 606 $acommunauté 606 $amulticulturalisme 606 $amigration 606 $ainsertion 606 $aintégration 606 $afête 606 $apolitisation 606 $adéveloppement communautaire urbain 606 $apolitique culturelle 606 $amarginalité 615 4$aUrban Studies 615 4$aHistory 615 4$acommunauté 615 4$amulticulturalisme 615 4$amigration 615 4$ainsertion 615 4$aintégration 615 4$afête 615 4$apolitisation 615 4$adéveloppement communautaire urbain 615 4$apolitique culturelle 615 4$amarginalité 700 $aArnaud$b Lionel$01319153 801 0$bFR-FrMaCLE 906 $aBOOK 912 $a9910495936303321 996 $aRéinventer la ville$93657325 997 $aUNINA LEADER 13150nam 22006732 450 001 9910787623703321 005 20151005020624.0 010 $a1-107-06965-3 010 $a1-107-05783-3 010 $a1-107-05456-7 010 $a1-107-05907-0 010 $a1-107-05561-X 010 $a1-139-15182-7 035 $a(CKB)2670000000502172 035 $a(EBL)1182951 035 $a(SSID)ssj0001080163 035 $a(PQKBManifestationID)12443962 035 $a(PQKBTitleCode)TC0001080163 035 $a(PQKBWorkID)11069155 035 $a(PQKB)10730769 035 $a(UkCbUP)CR9781139151825 035 $a(Au-PeEL)EBL1182951 035 $a(CaPaEBR)ebr11043804 035 $a(CaONFJC)MIL768910 035 $a(OCoLC)908077219 035 $a(MiAaPQ)EBC1182951 035 $a(PPN)261357441 035 $a(EXLCZ)992670000000502172 100 $a20110909d2013|||| uy| 0 101 0 $aeng 135 $aur||||||||||| 181 $ctxt$2rdacontent 182 $cc$2rdamedia 183 $acr$2rdacarrier 200 10$aHigh accuracy computing methods $efluid flows and wave phenomena /$fTapan K.

theory of computing. With developments of DNS and LES, practitioners are rediscovering waves as important in fluid flows, and capturing these numerically is central to high accuracy computing. Analysis of waves and its use in numerical methods in propagating energy at the right velocity (dispersion effects) and with right amplitude (dissipation) are essential. Most industrial codes using Reynolds-averaged Navier-Stokes equations with turbulence models cannot conceive of capturing waves. The new themes covered in this book are: ? Correct error propagation analysis ? Practical compact schemes and global analysis tool ? Aliasing error and its alleviation ? Spurious upstream propagating q-waves ? Explanation of the Gibbs phenomenon ? New 1D and 2D filters for LES/DNS without SGS modelling ? Anisotropic skewed wave propagation ? Development and analysis of dispersion relation preservation (DRP) schemes ?
