Validation and casework application of a Y chromosome specific STR multiplex

A series of validation experiments was performed for a Y chromosome specific STR multiplex system following the suggestions made by the Technical Working Group DNA Analysis Methods (TWGDAM). The multiplex PCR products were detected on Perkin-Elmer 373 and 377 automated sequencers using two labeling colors. No problems regarding the stability, robustness and sensitivity of the Y STR multiplex were observed. Mixture studies revealed a cut off rate similar to autosomal STRs for mixtures of male DNAs and no interference of any female admixture. The comparison of the Y STR results to the autosomal typing results for 56 nonprobative semen stains and swabs, showed a slightly higher success rate in detecting the semen donor’s alleles for the Y STR multiplex. Two examples are shown to illustrate the usefulness of Y STR typing for DNA mixtures. In one case the Y STR results confirmed an isolated exclusion; in the other case, the interpretation of a mixture was clarified since the Y STR results proved the presence of DNA from at least two semen donors. Y STR typing is a valuable addition to the forensic DNA testing panel.     

Indispensable,yet Invisible: Drinking water management as a local political issue in Swedish municipalities

ABSTRACT

Local policy-makers’ incentives to address an issue is conditioned by how they perceive public attention. Our study focuses on drinking water management at the municipal level in Sweden. Provisioning and management of drinking water is a responsibility of the local governments. Interviews with local politicians and public administrators in seven municipalities reveal that local policy-makers think that citizens view provisioning of drinking water as a taken for granted service, and also lack knowledge of and interest in drinking water issues. Public attention is further seen as a double-edged sword since engagement in water issues often is a result of problems with water provision. The findings are discussed from a theoretical perspective of the role of agenda-setting in public policy. It is argued that the view of policy-makers of citizens as unengaged negatively affects the incentives to bring drinking water to a prominent place on the local policy agenda.     

Conflict,Cooperation, and Institutional Change on the Commons

Rational choice scholarship posits two principal theories to explain why political institutions emerge and change: cooperation theory and conflict theory. We evaluate cooperation theory and conflict theory to explain the emergence of common property institutions among a group of Maasai pastoralists in southwestern Kenya. Our empirical results show that the change to common property is best explained by conflict theory.
