In this article we introduce a new scoring system for doing operational code analysis and test its reliability and validity by measuring and modeling President Jimmy Carter's operational code. Using speeches from the public record, we construct indices for the elements of the operational code construct. Based upon the valences and scaled intensities of verbs uttered in the speeches, President Jimmy Carter's views of the political universe and approaches to political action in different issue areas are identified and compared. The results of the analysis provide reasonable support for the face, construct, and content validity of the operational code indices. We find that Carter's view of the political universe and approach to political action were consistent across issue areas during the first three years of his term as president. Following the Soviet invasion of Afghanistan President Carter's support for human rights remained steadfast. Statistically significant shifts occurred in his views of the Soviet Union and others in the political universe and in his approach to political action regarding the conduct of U.S.-Soviet relations and other issues. 相似文献

Selection of twenty-four highly informative SNP markers for human identification and paternity analysis in Koreans 总被引:3,自引:0,他引:3
A number of DNA marker types suitable for human identification and parentage testing have been developed, of which single nucleotide polymorphisms (SNPs) merit attention as they are abundant, genetically stable, and amenable to high-throughput automated analysis. In this regard, 24 highly informative SNP markers representing each 22 autosome and both sex chromosomes were selected, and the allele and genotype frequencies of these SNPs were determined in a group composed of 30 unrelated Koreans. Based on frequency data from this group, the estimated probability of identity (P(I)) and probability of paternity exclusion (P(E)) with 22 autosomal SNP loci were 1.905x10(-10) and 98.9%, respectively. The SNPs in this study offer a small but highly accurate database that will be an essential reference for SNP-based forensic application in the future. 相似文献

This case-control study investigates the relationship between suicide and wealth in Kansas City, Missouri. House and personal property appraisal data on all victims of suicide from 1998 and 2002 and victims from a control population of deaths reported to the Jackson County Medical Examiner during the same time interval were obtained from the Jackson County Government website. The controls were matched to suicide cases by race, gender, year of death, and age at death (+/- 1 year). Data from the 426 members of each group of suicides and controls indicate that suicide victims were: 1) 77% more likely than controls to have lived in houses rather than in apartments or trailers, 2) more likely than controls to have lived in more expensive houses (mean values dollar 70,143 versus dolllar 61,513 respectively, p = 0.04) and 3) more likely to have killed themselves because of factors other than financial strain (8.0% of suicides showed financial strain). 相似文献
