How many people are there in winterveld?
ConclusionThe views presented in this paper give an indication of what can be expected from a properly conducted census in Winterveld. Certainly it will indicate a population much smaller than generally expected. Moreover, it brings into the spotlight what could be a general phenomenon: exaggerated informal population levels in South Africa, and, furthermore, it questions the reliability of indirect census survey procedures.
Urbanisation in Africa: lessons for urbanisation in the homelands.

Similarities between selected African states and the homelands are investigated with respect to rate of urbanization, adequacy of housing and services, and unbalanced growth. The suitability of Western models and standards for application to Africa's urban development is examined

Brauer groups of genus zero extensions of number fields
We determine the isomorphism class of the Brauer groups of certain nonrational genus zero extensions of number fields. In particular, for all genus zero extensions E of the rational numbers Q that are split by Q(√2), Br(E) ≅ Br(Q(t)).
