Correlation of surnames and Y-chromosome in Central-Brazil

In patrilineal societies, surnames and Y-specific haplotypes and haplogroups are expected to be correlated. This characteristic could help defining an initial pool of suspects in forensic genetics analysis. Here we evaluated this correlation in a sample of Central-Brazilian men. Surnames and Y-SNP haplogroup and Y-STR haplotype were analyzed in 55 pairs of Central-Brazilian men sharing surnames (n = 110). Seven haplogroups and thirty-two haplotypes have been observed, none correlated solely to any of the twenty-eight surnames represented here. In this sample, two men with the same surname showed a chance of 0.41 of sharing a Y-specific haplogroup. This chance is higher for surnames of intermediate frequencies, whereas rare surnames show distinct chances as zero and one. Observed results may be over-estimated due to a predominance of a specific haplogroup (P92R7 = 49%) in the sample, what makes it possible for two men with no coancestry to share this haplogroup. Considering STR, only three pairs of men shared haplotypes. The average difference between the haplotypes in each pair was 2.45 mutational steps. This relatively low correlation is due to some historical and cultural peculiarities of the country, what makes it improper for forensic purposes in Brazil.     

Inferring ancestral origin using a single multiplex assay of ancestry-informative marker SNPs

Tests that infer the ancestral origin of a DNA sample have considerable potential in the development of forensic tools that can help to guide crime investigation. We have developed a single-tube 34-plex SNP assay for the assignment of ancestral origin by choosing ancestry-informative markers (AIMs) exhibiting highly contrasting allele frequency distributions between the three major population-groups. To predict ancestral origin from the profiles obtained, a classification algorithm was developed based on maximum likelihood. Sampling of two populations each from African, European and East Asian groups provided training sets for the algorithm and this was tested using the CEPH Human Genome Diversity Panel. We detected negligible theoretical and practical error for assignments to one of the three groups analyzed with consistently high classification probabilities, even when using reduced subsets of SNPs. This study shows that by choosing SNPs exhibiting marked allele frequency differences between population-groups a practical forensic test for assigning the most likely ancestry can be achieved from a single multiplexed assay.     

Guantánamo Bay: Towards Legality?

This article outlines the US Supreme Court's approach to the habeas corpus entitlements of suspected terrorists detained in Guantánamo Bay and argues for the extension of constitutional habeas corpus rights to them. The article considers two ways in which the Supreme Court might carry out this task: first, 'the territorial approach' (based on domestic legal principles of 'unincorporated territories' and principles of leasehold), and secondly, 'the extraterritorial approach' (based on international purposive approaches to the reach of human rights treaties exemplified by the European Court of Human Rights' Article 1 jurisprudence). For reasons of effectiveness of protection, the Article expresses a clear preference for the latter. The House of Lords decision in R (Al-Skeini) v Secretary of State for Defence (2007) is proposed as a template for such a development. Finally the article refutes arguments rejecting such a development based on the 'trade-off thesis' and perceptions of judicial competence.     

Allele frequency distribution for 21 autosomal STR loci in Bhutan

We studied the allele frequency distribution of 21 autosomal STR loci contained in the AmpFlSTR^® Identifiler™ (Applied Biosystems), the Powerplex^®16 (Promega) and the FFFL (Promega) multiplex PCR kits among 936 individuals from the Royal Kingdom of Bhutan. As such these are the first published autosomal DNA results from this country.     

The Prosecution Role where Courts Decide Cases

This article explores the role played by prosecutors during the court stage of criminal proceedings. It complements Peter et al.’s chapter on negotiated case settlements in showing how the power to decide cases is divided between judges and prosecutors when cases are taken to court. Providing information as to, e.g. what influence prosecutors in the 11 study countries have on what evidence is brought to court in “normal” and accelerated court proceedings, this chapter explores the balance of responsibilities in court rooms across Europe.     

Crimes committed by terrorist groups: Theory,research, and prevention

Statement of Purpose: A decline in state-sponsored terrorism has caused many terrorist organizations to resort to criminal activity as an alternative means of support. This study examines terrorists' involvement in a variety of crimes ranging from motor vehicle violations, immigration fraud, and manufacturing illegal firearms to counterfeiting, armed bank robbery, and smuggling weapons of mass destruction. Special attention is given to transnational organized crime. Crimes are analyzed through the routine activity perspective and social learning theory. These theories draw our attention to the opportunities to commit crime and the criminal skills necessary to turn opportunity into criminality. Through these lenses, the research appraises the “successes” and “failures” of terrorists' engagement in crime. Because “failures” can result from law enforcement efforts to (1) interrupt criminal skill development, and/or (2) remove criminal opportunities via technologies and transportation systems, the research represents a best practices approach to the study and control of terrorism.
