The article uncovers evidence that the end of the Cold War has provideda dividend in terms of reduced transnational terrorism. Significant short-run and long-run effects are quantified with time-series analysis to be concentrated in reduced bombings and hostage-taking incidents. Presumably, this dividend is the result of less state-sponsorship of terrorism by the Commonwealth of Independent States and other states, as well as the result of measures taken by industrial states to thwart terrorist attacks. A dividend does not appear untilthe last three quarters of 1994, at which time moves were well under way to integrate Eastern Europe with the West. Moreover, prior to this period, significant efforts had been made among Western nations to augment cooperative efforts to curb terrorism and to bring terrorists to justice. Using data for 1970 through mid-1996, we also examine trends and cycles in terrorist modes ofattack. There is virtually no evidence of an upward trend in transnational terrorism, contrary to media characterizations. All types of terrorist incidents display cycles whose duration lengthens with logistical complexity. Any change in these cycles in the post–Cold War era is concentrated in the high-frequency or short-lived cycles.  相似文献

D8S384 is a tetranucleotide tandem repeat locus. In order to evaluate the forensic validation of D8S384, the genotype distributions and allele frequencies in ten populations from three main ethnic groups were investigated, including Germans, Slovakians, African Americans, Japanese, and Chinese (Jilin, Guangzhou, Nanning, Hailaer, Dali, and Chengdu). A total of 1011 unrelated individuals, 41 pedigrees, 30 disputed paternity trios and three personal identification cases were analyzed for D8S384 by Amp-FLP technique. Many kinds of tissues, body fluids, secreta and stains have been tested. The alleles were determined by comparison with a human allele ladder. The results showed that D8S384 typing was both precise and reliable. There were eight alleles in these populations. The genotype distributions conformed to Hardy-Weinberg equilibrium predictions. No mutation events were observed. With a maximum likelihood method, the mutation rate was indirectly estimated as 2.14 x 10(-5). The heterozygosity was 0.704 +/- 0.014 at D8S384 locus. All these results suggest that D8S384 locus is a useful marker for forensic identification and paternity analysis.  相似文献
