Gc-subtyping was carried out on blood stains that had been made on cotton and glass and stored under a variety of conditions ranging from -20 degrees to +56 degrees C. The limits of detection ranged from 2 weeks at 56 degrees C up to 92 weeks at +4 degrees C and greater than 116 weeks at -20 degrees C. Additional bands that have been reported in other studies could not be detected during this study, and this difference is thought to be due to storage of the samples in the liquid state. 相似文献

We have shown first, that if the electoral college was abolished the theoretically measured power of voters would increase and second, that in presidential elections the measure of voting power used does in fact have a highly significant impact on the decision as to whether or not to vote. Thus, the analysis predicts that the abolition of the electoral college would have a significant impact on voter participation. From a policy viewpoint, if we view participation in elections as desirable, this could be used as an argument in favor of direct election of the president. From a scientific viewpoint, we are able to make a strong and unambiguous prediction about the results of a (possible) future event from theoretical considerations. If the electoral college should be abolished, it will be possible to test our predictions. In addition, we have provided a further test of the rational behavior view of electoral participation and have shown that this model applies to presidential elections. Finally, we have shown that the theoretical measure of voting power does predict actual behavior. 相似文献

Suggesting that licensing may not only fail to accomplish its intended purpose, but may be counterproductive, the author asserts that licensing may not improve the quality of professional services, that licensing boards fail to discipline unethical or incompetent practitioners, and that actions taken against the unlicensed are more often aimed at eliminating competition, not incompetence. In addition, licensing laws may have negative side effects, including an increase in the cost of professional services, the creation of shortages and maldistributions in supply, ineffective use of paraprofessionals, and impediments to needed reforms in education, training, and services. He concludes that equally effective alternatives may be available that are less expensive and have less negative impact, and advocates a system of registration for all practitioners, as well as making other suggestions to improve the overall functioning of licensing boards. Finally, because of political realities, the author proposes a compromise between his ideal model and the current system. 相似文献
