Evaluating the forensic informativeness of mtDNA haplogroup H sub-typing on a Eurasian scale

The impact of phylogeographic information on mtDNA forensics has been limited to the quality control of published sequences and databases. In this work we use the information already available on Eurasian mtDNA phylogeography to guide the choice of coding-region SNPs for haplogroup H. This sub-typing is particularly important in forensics since, even when sequencing both HVRI and HVRII, the discriminating power is low in some Eurasian populations. We show that a small set (eight) of coding-region SNPs resolves a substantial proportion of the identical haplotypes, as defined by control-region variation alone. Moreover, this SNP set, while substantially increasing the discriminating efficiency in most Eurasian populations by roughly equal amounts, discloses population-specific profiles.     

Autosomic STR population data in two Caribbean samples from Colombia

In this work, a sample of 124 unrelated individuals from San Andres Island and Santa Marta City (Colombia) was studied for the nine STRs included in the AmpFlSTR Profiler kit (CSF1PO, D3S1358, D5S818, D7S820, D13S317, FGA, TH01, TPOX and vWA). Although these two populations are geographically apart, San Andres is an Island in the middle of Caribbean Sea (about 480 miles northwest the Colombian mainland) and Santa Marta City located in the coast, exact test showed no differentiation between both population samples (P=0.39445+/-0.0805). Therefore, allele frequencies and parameters of forensic interest were estimated for the global sample.     

Postmodern Global Governance and the Critical Legal Project<Superscript>1</Superscript>

The crisis of the New Deal constitutions and the shift to ?biopolitical’ forms of global governance in the late 20th century have dramatically disturbed the epistemological groundings and the political locations of contemporary critical legal movements. In epistemological terms, the emergence of the ?biopolitical’ has rendered transparent the impossibility of the binaries that have thus far sustained critical legal theories. With the divide between ?inside’ and ?outside’, ?base’ and ?superstructure’, ?state’ and ?society’, ?society’ and ?law’, no longer operative, critical legal movements have to outgrow their legal realist ?roots’. Could deconstruction provide here a viable option? Confronted by an order of governance that is now both ?global’ and ?imperial’, critical legal movements cannot recover a politics through such ephemeral theories. Rather, the future of critical legal movements must be located in an affirmation and promulgation of radically new constitutional principles which would confront the realities, but also harness the emancipatory potential, of the ?biopolitical’ horizon [eds.].     

Y-chromosome STRs in an Antioquian (Colombia) population sample

Haplotype data were obtained from a sample of 777 unrelated male individuals from Antioquia Department (Colombia), for eight Y-chromosome STRs (DYS19, DYS385, DYS389 I, DYS389 II, DYS390, DYS391, DYS392 and DYS393). A total of 442 different haplotypes were identified of which 334 were represented only once in the database and the most frequent haplotype was found in 32 individuals. A high haplotype diversity was found (99.45%). Genetic distances were calculated using previously published haplotype data and the lowest values were found for the comparisons with samples of lberian origin.     

Analysing the Impact of Price Shocks in Rural Economies: Do Household Responses Matter?

We analyse the impact of higher food prices on rural households in Tanzania focusing on the often neglected role of households’ behavioural responses. We introduce a new framework which considers the production response jointly with substitution effects in consumption and takes into account households’ market participation choices. Taking into account behavioural responses on consumption and production can significantly alter the sign and magnitude of the welfare impact in the long run.
