German unification and the subsequent breakdown of economic activity in East Germany initiated enormous migration flows from East to West Germany. People from East Germany moved towards West Germany, where wages are higher and employment opportunities are more favourable. Our paper takes a somewhat broader perspective; it analyses migration flows between four macro regions, i.e. East, North, So...

The effect of socio-cultural differences on health-seeking behaviour has been identified in the literature as the main cause of the disparity. Our study analyses the role of supply-side determinants, particularly access to service...

The origin and radiation of nacellid limpets (genera, Cellana and Nacella) are not well-resolved, but fossil records provide evidence of a historical range spanning throughout the PaciWc, including North America (Lindberg and Hickman, 1986) north and south Australia, New Zealand, Java, Chile, and east and west Antarctica (Powell, 1973). The modern biogeographic range of Cellana is mostly tropic...

Sickle cell disease (SCD) predominates in sub-Saharan Africa, East Mediterranean areas, Middle East, and India. Nigeria, being the most populous black nation in the world, bears its greatest burden in sub-Saharan Africa. The last few decades have witnessed remarkable scientific progress in the understanding of the complex pathophysiology of the disease. Improved clinical insights have heralded ...

Lion fecal DNA extracts from four individuals each from Yankari Game Reserve and Kainji-Lake National Park (central northeast and west Nigeria, respectively) were Sanger-sequenced for the mitochondrial cytochrome b gene. The sequences were aligned against 61 lion reference sequences from other parts of Africa and India. The sequence data were analyzed further for the construction of phylogeneti...
