ABSTRACTStructural and electrical characterization of laser recrystallized LPCVD silicon films on amorphous substrates using a shaped cw laser beam have been performed. In comparing the results to data obtained using a circular beam, it was found that a significant increase in grain size can be achieved and that the surface morphology of the shaped beam recrystallized material was much smoother. It was also found that whereas circular beam recrystallized material has a random grain structure, shaped beam material is highly oriented with a <100> texture. Finally the electrical characteristics of the recrystallized film were very good when measured in directions parallel to the grain boundaries.

This chapter examines the politics of the currency in West Africa from the beginning of the twentieth century. A public series of debates over the nature of the currency occurred in West Africa during both the colonial and independence periods. Since 1983, West African countries have been pioneers in Africa in developing new strategies to combat overvaluation of the currency and reduce the control of government over the currency supply. The chapter charts the evolution of West African currencies as boundaries and explores their relationship to state consolidation. It shows that leaders in African capitals managed to make the units they ruled increasingly distinct from the international and regional economies, but the greater salience of the currency did not end up promoting state consolidation. Rather, winning the ability to determine the value of the currency led to a series of disastrous decisions that severely weakened the states themselves.

The article addresses the needs of educational system in context of rapidly developing globalization and explores internationalization of higher education as one of the main factors which contributes to integration of international dimension to professional training at universities. Different components and strategies of internationalization, such as strong collaboration in teaching, internationalization of the curriculum, cooperation in researches and knowledge production, students and professors’ mobility, and participation in international networks are analyzed in connection to education reform in Russia. The article provides the comparison of internationalization policies in Russian and Vietnamese education systems, argues that innovations in higher education should be adjusted to the national interests, traditions and mentality and finally describes new strategies in collaboration of Russia and Vietnam in the field of education.
