Inferring recent human phylogenies using forensic STR technology

STR loci are characterized by extremely high mutation rates and thus, high levels of length polymorphism both within and among populations. In addition, much of the observed variation is believed to be nearly selectively neutral. Because of these features, STRs are ideal markers for genetic mapping, intra-species phylogenetic reconstructions and forensic analysis. In the present study, we investigate the application of five STR loci (CS1PO, TH01, TPOX, FGA and vWA) routinely used in forensic analysis for delineating the phylogenetic relationships of 10 human populations representing the three major racial groups (African-Caribbean, Croatian from the island of Hvar, East Asian, Han Chinese, Italian, Japanese, Portuguese, UK Caucasian, US Caucasian and Zimbabwe). The resulting tree topology exhibited strong geographic and racial partitioning consistent with that obtained with mtDNA haplotypes, Y-chromosome markers, SNPs, PAIs (polymorphic Alu insertions) as well as classic genetic polymorphisms. These findings suggest that forensic STR loci may be particularly powerful tools and provide the necessary fine resolution for the reconstruction of recent human evolutionary history.

Who should be chef? The dynamics of valence evaluations across income groups during economic crises

In this paper, we investigate partisan rationalization in valence politics by trying to better specify the direct and indirect effects of the economy on government support. To do so, we examine how income levels moderate the influence of objective economic conditions on perceptions of which party is the best manager of the economy during a period of economic crisis, 2004–2010, in the United Kingdom. We find that low-income voters are more responsive in their assessments of the incumbent Labour government based on unemployment, as are high-income voters in terms of inflation. In addition, high-income voters tend to behave in a manner consistent with partisan rationalization, while low-income voters do not. These conclusions offer important implications for the effectiveness of electoral control of government policy, as well as the quality of representation.     

Harry Hopkins and Soviet Espionage

One of the intriguing unidentified cover names in the Venona decryptions released in the mid-1990s was ‘19’, a Soviet source senior enough to report taking part in a conversation with President Roosevelt, Prime Minister Churchill, and Vice-President Wallace at the 1943 Trident conference. While some historians thought the evidence too ambiguous to identify the real name behind ‘19’, others built a case that it was presidential adviser Harry Hopkins. Alexander Vassiliev's notebooks, made public in 2009, resolved the issue by firmly identifying ‘19’ as State Department official Laurence Duggan. There remain, however, writers who refuse to accept the evidence that ‘19’ was Duggan and insist that Hopkins was a Soviet agent on the basis of insubstantial evidence.     

Natural resource rents and elite bargains in Africa: Exploring avenues for future research

This article explores the recent debate over the quality of Africa's growth episode of the past decade, specifically insofar as it pertains to the pitfalls of commodity-dependent growth and the hypothesised ‘resource curse’. In addition, the article focuses on why political and economic institutions are important, and why they are indicators for the likely development impacts of Africa's evident mineral and hydrocarbon wealth. Third, it suggests a useful theoretical framework for understanding these indicators, especially with regard to the differing constraints under which foreign investors operate and interact with host countries. Developing on the latter points, the article looks at the nature of Chinese foreign investment in Africa's extractive industries. Finally, the article suggests an agenda for future research that could better inform development policy for the purpose of promoting high-quality growth in Africa.
