Improvements in detection limits/sensitivity and lower sample consumption are potential benefits of reducing PCR reaction volumes used in forensic DNA typing of crime scene samples. This premise was studied first with experimental mixtures and a nine-loci megaplex, which demonstrated stochiometric amplification and accurate detection. Next, adjudicated casework samples were subjected to amplification under 15 different template DNA to PCR reaction volume ratios. Reduction of PCR reaction volume and DNA down to 10 microL and 0.500 ng, respectively, produced identical profiles with the same signal intensity and heterozygous allele peak height ratio (HR). Reduction to 5 microL and 0.063 ng yielded HR values that were slightly affected in one to three STR loci. PCR reaction volume reduction can enhance detection and sensitivity while reducing the consumption of irreplaceable crime scene samples. 相似文献

Initially Norwegian climate policy was very ambitious and Norway stood forth as a pusher on the international scene. Over time Norwegian policy has become more sober, stressing the need for differentiated commitments and flexible implementation. In contrast to the initial enthusiastic phase, climate change policy has been increasingly seen in pragmatic economic terms. Still, Norway is no laggard, as it has shown more willingness to pay for abatement measures than many other countries. 相似文献

This study reports on the effectiveness of a year-long field experiment involving training in transformational and transactional leadership in the public and private sectors. Using before and after training assessments by employees of several hundred Danish leaders, the analysis shows that transformational leadership training is associated with increases in behaviors linked to both transformational leadership and the use of verbal rewards, but only for public sector organizations. There is no impact in private sector organizations. Transactional leadership training appears to be equally effective in stimulating the use of pecuniary rewards in both public and private organizations. 相似文献

The literature on the boundary between civil and uncivil society has reached an impasse between approaches that oppose these societies to each other and those that dismiss the boundary altogether. This article suggests an analytical shift to a governmental approach that asks how the relation between civil and uncivil society figures in social practices. The approach is applied to the case of the Danish anti-radicalization discourse which revolves around subjects that cross the boundary. Through a discourse analysis of governmental papers, the author argues that the boundary appears twice. First, as a categorical difference that is simultaneously erected and annulled. This is not a paradox that must be superseded but one which structures a rationality of the governed in Civil Society that a governmental rationality pegs itself to inside an indefinite time. Second, this rationality is only possible through the rejection of violence. This creates a void which serves as an object of the discourse while existing outside the indefinite time of governmentality. 相似文献

The recent empirical literature on redistribution and developmentemphasizes two main evidences: (i) more redistribution generallyinduces higher growth rates and (ii) more inequality does notnecessarily increase the political demand for redistribution.These stylized facts are at odds with the correlations observedin developed countries. Several theoretical arguments can beadvanced to explain these puzzles. In this paper, it is shownthat ``vote purchases'' may be seen as an additional argument toexplain puzzle (ii). We formalize this idea and examine theconditions under which vote bribes may be an obstacle toredistribution (and thus to growth) in a developing economy. 相似文献
