Persistence of Ancestral KhoeSan Mitochondrial Patterns in Contemporary South African Populations
Annals of Human Genetics, EarlyView.Abstract Introduction Southern Africa has been inhabited by hunter‐gatherers for at least 20,000 years and has received diverse immigration flows in the last 2000 years. The original inhabitants have interacted with the pastoralist migrants from Eastern Africa (∼2000 ybp), followed by the southern Bantu migration arriving some 1000 ybp, and more ...

The spiral structure of galaxies
, 2006 We start from the author's metric for a rotating and accelerating Universe and we calculate the force acting on a particle in it. This force consists of two parts: one is derived from a potential, and the other describes a Coriolis force coming from the overall rotation of the Universe.

However, the concept of “political professionalisation” is deployed inconsistently, making these claims difficult to assess. This article develops a framework to measure professionalisation across two dimensions: career professionalisation ...
