The promotion of the German language abroad and of German Studies plays a central role in German Foreign Cultural Policy. With regard to Sub-Saharan Africa, otherwise a peripheral region for foreign policy, German as foreign language is firmly established as second language after English. Learners especially in Francophone West and Central Africa have increased over the past decade. Numerous funding programmes and actions are supported by German nongovernmental organizations at college/university levels. But bilateral cooperation between German and African academic institutions are challenged both by negative perceptions of the ‘Global South’ among Western colleagues and by an infrastructure adverse to research and to career development in most African countries. Additionally, North/South relations are traditionally seen in terms of (under-)development by German institutions, effecting cooperation. The paper develops a differentiated picture of African Studies in Africa, and outlines benefits that can be attained through collaboration ‘at eye-level’.  相似文献

ABSTRACT State per capita income differences narrowed considerably between 1939 and 1976. However, this convergence has been incomplete. We examined the sources of relative per capita income growth using an augmented growth model and a panel of the 48 contiguous states from 1939 to 2004. We explored the effect of tax burdens, public infrastructure, size of private financial markets, rates of business failure, industry structure, climate, educational attainment, and technology production. Our results show that a state's technology and its college attainment rates are the main factors that allow some state's per capita income to remain above those of other states.  相似文献
