Peri-urban mobilities, modal diversification and new dynamic of public institution : how to change mobilities governance in peri-urban area of middle size cities to enter into sustainability in Britany and Hauts-de-France Region?
The peri-urban space of medium-sized towns is marked by self-car-mobility, with a limited mobility option offer, and is a source of inequity for non-motorized or poorly-motorized people in a context of increased concentration of the role of urban centers. This sparsely populated area was still large...
For a relational approach to modern literary Arabic conditional clauses
Based on novels written in Modern Standard Arabic published between 1963 and 2005 and from the entire Arab world, this article suggests how the hypothetical systems of this variety of language no longer correspond to the established "classical" model. Specifically, it demonstrates that the so called...
The Sociological Discourse on Inequality and Social Class in France
International audience Over the past three decades social inequality has grown in France, as in many other countries. Paradoxically, however, during that same period the dominant discourse concerning French society, both in the social sciences and politics, has largely tended to conceal this growing...
