This article is a review of the PhD thesis undertaken by Joanna Vearey that explores local government responses to the urban health challenges of migration, informal settlements, and HIV in Johannesburg, South Africa. Urbanisation in South Africa is a result of natural urban growth and (to a lesser extent) in-migration from within the country and across borders. This has led to the development ...
This study aims at a high-resolution analysis of Y-chromosome J and E haplogroups among Andalusians to reconstruct Neolithic, protohistorical and historical migrations in the Mediterranean region. Genotyping of two samples from Granada (n=250 males) and Huelva (n=167 males) (Spain) with Y-chromosome binary and microsatellite markers was performed, and the results compared with other Mediterrane...
This paper examines recent developments in migration studies. It reviews literature related to the potential role of internal population movement in the occurrence of schistosomiasis in Brazil and modifies Prothero's typology of population movement for use in Brazil. This modified classification system may contribute to a better understanding of schistosome transmission as well as improved rese...
R-lineage mitochondrial DNA represents over 90% of the European population and is significantly present all around the planet (North Africa, Asia, Oceania, and America). This lineage played a major role in migration "out of Africa" and colonization in Europe. In order to determine an accurate dating of the R lineage and its sublineages, we analyzed 1173 individuals and complete mtDNA sequences ...
River systems are vulnerable to natural and anthropogenic habitat fragmentation and will often harbor populations deviating markedly from simplified theoretical models. We investigated fine-scale population structure in the sedentary river fish Cottus gobio using microsatellites and compared migration estimates from three FST estimators, a coalescent maximum-likelihood method and Bayesian recen...

Our analysis of survey data from 7 EU countries during the period 2002-2003 suggests that personal opinions about...

This is because different rules and regulations apply to different types of immigration, and because the economic effects can be rather different. Immigration rules usually distinguish between entry for humanitarian reasons (for example, as refugees or for family reunification), and...
