Genetic profile of a multi-ethnic population from Guiné-Bissau (west African coast) using the new PowerPlex 16 System kit

Allele and haplotype frequencies of 15 chromosome STR loci included in the kit PowerPlex16 System from Promega, were determined in a sample of unrelated males from Guiné-Bissau, a country from the west African coast. All individuals were subjected to an interview in order to make sure that their ancestors belonged to the same ethnic group. This way we intended to look for possible inter-ethnic differences. PowerPlex 16 includes STRs not studied before in any multi-ethnic population. The kit includes two new allele markers (Penta D and Penta E), which are very useful either in forensics or population genetic studies. The Guinean population presents significant differences when compared with other African populations.     

Tug of war: street trading and city governance in Kumasi,Ghana

Kumasi, Ghana, has witnessed accelerated population growth in the past two decades, leading to a significant increase in joblessness following years of economic decline and labour market liberalisation. As a survival strategy, residents have resorted to street trading, making it an important source of livelihood. However, its associated implications for urban governance and management has placed city authorities in the spotlight over the years. Examining the daily struggles that occur between city managers and street traders, this article finds that various strategies adopted by city authorities to decongest the streets have proved futile. Rethinking what could be a sustainable strategy for decongesting the streets of traders, the article concludes that chasing the traders out of the streets is not the panacea to solving the problem unless well coordinated land-use planning and appropriate regulations are competently enforced.     

Development policy and the democratic peace in Sub-Saharan Africa

The contention that ‘democracies do not ?ght one another’ has gained widespread acceptance in the discipline of international relations, as well as among policymakers and international institutions. In the post-Cold War era, this contention has formed part of the justi?cation for making development assistance conditional on democratic reforms in recipient countries. This article explores the democratic peace thesis in relation to Sub-Saharan Africa, and argues that the relationship between peace and democracy is much more complex than commonly allowed for in conventional liberal analyses. Contemporary development policies that are intended to promote peace, democracy and stability are frequently implicated in the production and continuation of con?ict. Accordingly, the article contends that many of Africa’s conflicts and so-called ‘failed states’ are best understood in light of policies inspired, in part, by the principles of the democratic peace thesis. The argument is illustrated with reference to four countries on the African continent: Côte d’Ivoire, Rwanda, Sierra Leone and Zambia.
