I'm particularly interested in exploring how (usually informal) governmental strategies hamper out-group acts of assistance provision to prevent social/political mobilisation and social cohesion within multi-"ethnic" societies (a potential threat to political regimes). As a result, in these contexts, assistance and support emerge as a primarily in-group phenomenon (by group I mean demographic segments that have the same nationality). Most of the literature, especially the one on the Middle East, focus on service/aid provision and the creation of political constituencies, which is a slightly different matter. Thanks for your help.
