Y-chromosome STR haplotype diversity in Brazilian populations

A sample of 198 unrelated males distributed among the five geopolitical regions in Brazil were typed for the minimal Y-STR haplotype composed of microsatellite loci DYS19, DYS385I/II, DYS389I, DYS389II, DYS390, DYS391, DYS392 and DYS393. Gene frequency data, gene diversity, haplotype diversity and power of discrimination were estimated. An AMOVA indicated that 99.97% of the haplotypic variation is found within regions and only a small 0.03% and non significant variation is found among the five regions (Fst=0.00031, P-value=0.43). This result suggests that a single national database of Y-STR haplotypes can be used in the quantitative assessment of matches in forensic casework in the Brazilian population. A significant haplotype diversity of 99.8% was found and 172 different haplotypes were observed in 198 chromosomes. Haplotype (14-11, 14-13-29-24-11-13-13) with five occurrences in 198 chromosomes was the most frequent in Brazil.     

The Limitations of Water Regulation: The Failure of the Cochabamba Concession in Bolivia

This article examines the limitations of governmental capacity to regulate private sector participation in urban water supply in developing countries through an analysis of the most dramatic failure to date of a major franchise contract for supplying water and sanitation services to a large city – the 40-year concession awarded in September 1999 to Aguas del Tunari (AdT) in Cochabamba, Bolivia. Five months later, the population rioted against water tariff increases and the contract was cancelled. The paper analyses the background, context and factors that explain the failure of the concession and seeks to draw lessons for the regulation of future concessions.     

The Spanish School of the Sixteenth and Seventeenth Centuries: A Precursor of the Theory of Human Rights

In this paper the author examines certain ideas of the Spanish School of the sixteenth and seventeenth centuries which directly inspired the School of Hugo Grotius in the seventeenth, thus opening the way towards possible declarations of human rights such as that of United Nations. The line of thought which extends from Francisco de Vitoria (1492/93–1546) to Francisco Suárez (1548–1617) is given the name of the "Spanish natural law and law of nations School."
