Tourim, gentrification and neighborhood management in regenerated-cites: towards a “post-regeneration urbanism”

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 $q; t$-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 freeL’arrangement Ish a été introduit par Armstrong pour donner une nouvelle interprétation des nombres $q; t$-Catalan de Garsia et Haiman. Armstrong et Rhoades ont montré qu’il y avait des ressemblances frappantes entre l’arrangement Shi et l’arrangement Ish et ont posé des conjectures. L’une d’elles est de savoir si l’arrangement Ish est un arrangement libre ou pas. Dans cet article, nous vérifions que l’arrangement Ish est supersoluble et donc libre. De plus, on donne une condition nécessaire et suffisante pour que l’arrangement Ish réduit soit libre

Ethane-1,2-diyl bis­(benzene­dithio­ate)

In the crystal structure, the title compound, C16H14S4, is located on an inversion center and exhibits a gauche+–trans–gauche− conformation in the S—CH2—CH2—S bond sequence. The S—C=S plane makes a dihedral angle of 30.63 (17)° with the phenyl ring. An inter­molecular C—H⋯π inter­action is observed
