Fourteen southern and border states established a same-day presidentialprimary on 8 March 1988. This analysis shows that this SuperTuesday, in several senses, was less than super. The resultsturned out to be less satisfying than its Democratic founderspreferred but less upsetting than its critics anticipated. DespiteSuper Tuesday, Iowa and New Hampshire remained dominant in the1988 presidential primaries. Although voter turnout increasedslightly over 1984 and the results contributed mightily towardsettling the nomination in the Republican party, Super Tuesdayneither settled the Democratic nomination nor gave meaningfulmomentum to the more moderate Democratic candidates. 相似文献

Since 1868 nineteen Prime Ministers have answered parliamentary questions, made statements, given major speeches, and intervened in debates in the House of Commons. This article presents a comparative and quantitative analysis of PMS' behaviour patterns on these four dimensions. Key findings include: the importance of 1940 as the critical break between a traditional and a modem form of parliamentary activity, in which Prime Ministers make fewer contributions to Commons proceedings altogether, fewer speeches and far fewer interventions in debates than in the pre-1940 period, but more statements; the emergence of question time as the absolutely dominant form of prime ministerial activity in the Commons, especially from the mid-1970s onwards; and the distinctiveness of Thatcher's minimalist Commons activity, when set against other post-1940 PMs. 相似文献

The introduction of a standardized paternity index (PI) for the statistical evaluation of blood group findings in cases of disputed paternity is proposed and explained. By using the PI as parameter, it is not necessary to give the information of the probability of paternity in percent. The PI includes the full information of the blood group findings. In addition to that, by using the suggested standardization based on the probabilities of error according to Schulte Mönting and Walter the test volume is also taken into account. The interpretation of the mathematical result is given by verbal predicates, the limitations of which are orientated by the verbal predicates for the probabilities of error according to Schulte Mönting and Walter, published by us elsewhere. Besides the essential fact that the test volume is taken into account, the most important advantage of this procedure is that the mathematical result is involved in the court decision only by the PI (which is free of any valuation) and its verbal predicate and not by sometimes relatively high percentages, which may be misunderstood by laymen. 相似文献
