Ethnic colonies. Origination, function and change in the case of Turkish mosques and cafés
The first three chapters deal with theories of global and national aspects of the framework of migration processes, showing that global and local processes are intervowen and that their common causes and continuity. It is also shown that migration is a constitutive feature of urban development, and that ethnic-cultural heterogeneity is the norm in German cities. Then, the concept of "ethnic colony" is introduced, which, in the empirical part, is described and analyzed in the case of Duisburg, Germany, where men of the first and second immigrant generations in Turkish mosques and cafés have been interviewed. The author wanted to find out when and under which conditions these institutions have been founded, what functions they had and have, the structure of the institutions, their relation with macro-structures, and their integrative respectively disintegrative tendencies. The appearance of seeming homogeneity was followed by segmentation and differentiation, which again was followed by accomodation and normalization, while the future may bring exclusion, stagnation, and regression.
