The 1986 Davis v. Bandemer decision of the U.S. Supreme Courtdeclared partisan gerrymandering to be justiciable, but overruledthe federal district court's judgment that the Indiana legislativeredistricting plan was unconstitutional. The Court split onthe question of justiciability, and those justices who favoredjusticiability disagreed on the appropriate tests to apply intesting a districting plan for unfair partisan gerrymandering.The Court did not specify a clear measure and standard for outlawinggerrymandering. This gives state districting authorities anddistrict courts little guidance in dealing with gerrymandering.If, however, a successful measure and standard are developed,this action is likely to be beneficial to the states. 相似文献

In the election to the Althingi on 25 April 1987, the established party system in Iceland received its greatest blow so far. The four main parties between them managed only three-quarters of the valid votes, the Independence Party and the People's Alliance, both suffered their worst defeats ever. The new parties had a field day, as the Citizens' Party—the first major splinter group from the large Independence Party since its foundation—and the Women's Alliance received over 10 per cent of the votes each. Thus, the signs of crisis in the established party system—increasingly visible since around 1970—indicate an uncertain future for the four-party format in Icelandic politics. 相似文献

The policy sciences have advanced in the past by introspection, and there appears to be a need for a return to such self-conscious examination of the field of inquiry. A design orientation offers a useful framework for such an examination. It requires reconsideration of some of the fundamental premises of policy inquiry. This article explores what impact design might have on the conventional process framework and then proceeds to discuss the development of a design perspective. 相似文献

Adolescent girls aged 12 through 16 years, identified as either educable mentally retarded, behaviorally disordered, learning disabled, or nonhandicapped, were rated by their teachers on the Behavior Problem Checklist. Analysis of these ratings revealed significant differences for pupil category, Behavior Problem Checklist dimension, and category-by-dimension interaction. Behaviorally disordered students showed a greater degree of maladjustment than the retarded and nonhandicapped students on all four checklist dimensions, and exceeded the learning disabled on three dimensions (not Personality Problem). Implications for further research and special educational practices based on the present findings are discussed.Received Ed.D. from University of Virginia.
