This research project aims at generating much-needed scientific knowledge on micro-level processes of the interplay of language, migration, and (neo-)nationalism through in-depth, in situ ethnographic investigations, interviews/focus groups with participants from diverse social, linguistic, and ethnic backgrounds, and the analysis of covert/overt language policy and practices. This research will help understand how to counteract such alarming social trends, how to prepare educators and policy makers, and how to contribute to a mentality change against hatred, racism, and other forms of discrimination in favor equity, democracy, and diversity.
