How to paraphrase this paragraph?
Classic studies of the diaspora have highlighted its dependence on the nation-state, its politics of long-distance nationalism, and its troubled relationship with the country of settlement. However, anthropological and sociological research on diaspora, globalization, and transnationalism has demonstrated the limitations of such nation-centric approaches, not least through empirical studies of centrifugal and multinodal connections in the diaspora that do not necessarily support connections.
