Evaluation of haplotype discrimination capacity of 35 Y-chromosomal short tandem repeat loci

The haplotype discrimination capacity of the 9 Y-chromosomal short tandem repeat (Y-STR) loci comprising the so called minimal haplotype together with additional 26 recently described single-copy Y-STRs was evaluated within 391 males from Germany, The Netherlands, and Turkey. The aim of this study was to identify the minimum number of Y-STRs needed in addition to the recommended 9 minimal haplotype loci or the 11 SWGDAM loci for individualizing male lineages. Highest gene diversities were shown for DYS385 loci, DYS449, DYS481, DYS570, DYS447, DYS576, DYS389-II, and DYS390 (D=0.7518-0.8746). The five Y-STRs DYS447, DYS449, DYS481, DYS570, and DYS576 comprised the smallest set of loci in addition to the previously recommended standard Y-STRs leading to the individualization of all males from each single population group. Complete resolution of the pooled population was achieved by the additional genotyping of two further loci, DYS446 or DYS505 and DYF406S1 or DYS522.     

Human capital and social capital in criminal networks: introduction to the special issue on the 7th Blankensee Colloquium

This essay and review on criminal network analysis provides an introduction to the special issue “Human Capital and Social Capital in Criminal Networks”. It traces the history of the application of network analysis in the study of organized crime since the early 1970s. It argues that while criminal network analysis has brought a new level of methodological rigor to the study of organized crime, a number of limitations have become apparent. These include the problem of missing data and the challenges encountered in adequately capturing latent structures, individual characteristics of network members and socio-ecological conditions.     

The interdisciplinary dimensions of the study of organized crime

This essay and review systematically charts the various influences from other areas of scientific research, including economy, psychology, and neurobiology, on the study of organized crime. Drawing on an analysis of American and international literature, metaphorical, and substantive references to other disciplines are highlighted on five levels of observation: the individual “organized criminal,” the activities these individuals are involved in, the associational patterns through which they are connected, the power structures that subordinate these individuals and collectives to common or particular interests, and the relations between these individuals, structures and activities on the one hand, and the legal spheres of society on the other. It is argued that a research program aiming at building up a cumulative body of knowledge is needed to overcome the shortcomings of the current eclectic use of concepts and theories from other disciplines.     

Development policy and international administrative relations: The aspect of education and training

Within the framework of administrative co-operation, transnational arrangements of education and training constitute a delicate activity. Many reverberations of colonial and early post-colonial times can still be felt in this domain. Nevertheless, the problems of transfer, be it doctrine, technical implementation or practical experience, are still very apparent and will probably continue. This article traces the progress of education and training through post-colonial history until the present, discusses the merits of the different approaches taken by the most active Western institutions and identifies the major experiences and lessons regarding the various problems of transfer. The debate concentrates on the specific activities and experiences of the most recent programmes offered by the Graduate School of Administrative Sciences in Speyer in co-operation with the public administration branch of the German Foundation for International Development.
