Sommario/riassunto |
|
The contributions in this volume consider the question of migrant agency, how Western societies are both transforming migrants, and being transformed by them. It is informed by debates on the new 'transnational mobility', the immigration of Muslims, the increasing importance of human rights law, and the critical attention paid to women migrants. |
