The advent of impact assessment as a tool of policy is the latest chapter in our understanding of the relationship between science and politics. As such, it presents at least two challenges to democratic politics. Given its emphasis on appropriate procedural character of conteniporary democratic systems. And by raising the value of technical and scientific information in environmental disputes, impact assessment poses a challenge to existing concepts of popular sovereignty, based as they are on interest and preference rather than knowledge. These challenges, however, do not rep- resent irreconcilable differences. Although there may be an inherent ten- sion between impact assessment and democratic politics, there are also areas of affinity between the two. And we are destined to accept and adapt to this tension because, in fact, understanding is one of our principal defenses against tyranny. 相似文献

Allele and genotype frequencies for three recently described short tandem repeat loci D1S1656, D12S391, and D18S535 were determined in a population sample from Asturias (North Spain). The loci were amplified using a fluorescence based PCR method and were typed automatically. No deviation from Hardy-Weinberg expectations were observed. The three loci proved to be highly discriminating and the allele frequencies observed are similar to those of the other European populations that have been typed for these loci to date. 相似文献

Several theorists contend that male university/college students who physically, sexually, and psychologically abuse their
female dating partners are more likely than men who are not abusive to adhere to the ideology of familial patriarchy. These
scholars also argue that men who hold familial patriarchal attitudes and beliefs, and who are supported by their male peers,
are most likely to victimize their dating partners. This research provides quantitative data from a national representative
sample of Canadian male undergraduate students that support these hypotheses.
This study was sponsored by a grant from the family Violence Prevention Division, Health and Welfare Canada The views expressed
in this paper are those of the authors and do not necessarily reflect those of Health and Welfare Canada. 相似文献

A simple procedure based on a common silica gel column chromatography for the isolation of Delta9-tetrahydrocannabinolic acid A (Delta9-THCA-A) from hemp in a multi-milligram scale is presented. Further, the decarboxylation reaction of Delta9-THCA-A to the toxicologically active Delta9-tetrahydrocannabinol (Delta9-THC) at different analytical and under-smoking conditions is investigated. Maximal conversion in an optimised analytical equipment yields about 70% Delta9-THC. In the simulation of the smoking process, only about 30 % of the spiked substance could be recovered as Delta9-THC. 相似文献
