The European community software directive: The United Kingdom implementation

Conclusion The Regulations appear to have reinforced the protection available to software producers under United Kingdom law. The provisions of the Software Directive and the Regulations are complex and not without significant inconsistencies which are likely to prove to be a source of litigation. The drafters of the Regulations chose, unlike many of its European partners, not to adopt the wording of the Software Directive but to write their own interpretation, adding an element of uncertainty to the law in this area, which is perhaps inevitable bearing in mind the linguistic problems of translating and interpreting any directive coupled with the ambiguity and omission of definitions of several key terms. More important, however, than any academic argument will be the practical impact of the new law and its effectiveness in achieving its aim.     

Issues,the Spatial Theory of Voting,and British General Elections: A Comparison of Proximity and Directional Models

Competing spatial models of voter choiceare compared in the context ofparliamentary representatives selectedthrough single-member district, pluralityelections where party platforms areemphasized over individual candidates.Respondents of the 1987, 1992, and 1997British general election surveys ratepolitical parties on a series of issuescales. Ordered logistic regressions ofparty evaluations under proximity,directional, and mixed models reveal thatthe classic spatial model and thedirectional model perform equally well.Differences center on perceptions of thestatus quo, as voters appear to evaluatethe incumbent party (here, theConservatives) slightly differently thanminority parties (Labour and the LiberalDemocrats). The proximity model worksbetter for voter evaluations of governingparties while the directional model workswell for opposition parties.     

The Limits of Ecological Inference: The Case of Split-Ticket Voting

We examine the limits of ecological inference methods by focusing on the case of split-ticket voting. Burden and Kimball (1998) report that, by using the King estimation procedure for inferring individual-level behavior from aggregate data, they are the first to produce accurate estimates of split-ticket voting rates in congressional districts. However, a closer examination of their data reveals that a satisfactory analysis of this problem is more complex than may initially appear. We show that the estimation technique is highly suspect in general and especially unhelpful with their particular data.
