Tourim, gentrification and neighborhood management in regenerated-cites: towards a âpost-regeneration urbanismâ
For these two decades many cities have succeeded in urban regeneration, based upon the simple concept that is to
make a city people-friendly and comfortable to live in. The emergence of "regenerated" cities has raised traditional
problematic issues: gentrification and neighborhood management. Tourism policy would boost those processes that
began to be identified in some regenerated cities like Torino and Barcelona in the late 1990s. The sustainable
management of areas where socially vulnerable people live seems to be included in regeneration process, which
would be described as "post-regeneration urbanism".Peer Reviewe
The freeness of Ish arrangements
International audienceThe Ish arrangement was introduced by Armstrong to give a new interpretation of the -Catalan numbers of Garsia and Haiman. Armstrong and Rhoades showed that there are some striking similarities between the Shi arrangement and the Ish arrangement and posed some problems. One of them is whether the Ish arrangement is a free arrangement or not. In this paper, we verify that the Ish arrangement is supersolvable and hence free. Moreover, we give a necessary and sufficient condition for the deleted Ish arrangement to be freeLâarrangement Ish a Ă©tĂ© introduit par Armstrong pour donner une nouvelle interprĂ©tation des nombres -Catalan de Garsia et Haiman. Armstrong et Rhoades ont montrĂ© quâil y avait des ressemblances frappantes entre lâarrangement Shi et lâarrangement Ish et ont posĂ© des conjectures. Lâune dâelles est de savoir si lâarrangement Ish est un arrangement libre ou pas. Dans cet article, nous vĂ©rifions que lâarrangement Ish est supersoluble et donc libre. De plus, on donne une condition nĂ©cessaire et suffisante pour que lâarrangement Ish rĂ©duit soit libre

Ethane-1,2-diyl bisÂ(benzeneÂdithioÂate)
In the crystal structure, the title compound, C16H14S4, is located on an inversion center and exhibits a gauche+âtransâgaucheâ conformation in the SâCH2âCH2âS bond sequence. The SâC=S plane makes a dihedral angle of 30.63â
(17)° with the phenyl ring. An interÂmolecular CâHâŻÏ interÂaction is observed
