e propose a comprehensive statistical model for analyzing multiparty, district-level elections. This model, which provides a tool for comparative politics research analogous to that which regression analysis provides in the American two-party context, can be used to explain or predict how geographic distributions of electoral results depend upon economic conditions, neighborhood ethnic compositions, campaign spending, and other features of the election campaign or aggregate areas. We also provide new graphical representations for data exploration, model evaluation, and substantive interpretation. We illustrate the use of this model by attempting to resolve a controversy over the size of and trend in the electoral advantage of incumbency in Britain. Contraiy to previous analyses, all based on measures now known to be biased, we demonstrate that the advantage is small but meaningfkl, varies substantially across the parties, and is not growing. Finally, we show how to estimate the party from which each party's advantage is predominantly drawn. w e propose the first internally consistent statistical model for analyzing multiparty, districtlevel aggregate election data. Our model can

The travel agency industry is characterized by many small businesses that have recently been under pressure from changing external factors including those in the technological and competitive environments as well as from the “customers ” on both sides of their transactions-- their clients and the service providers. This paper provides a theoretical basis and empirical support for six traditional roles performed by the travel agent that are firmly grounded in classical and neoclassical organizational theory. These roles include Clearinghouse, Information Source, Specialist, Negotiator/Mediator, Scout and Cost Reducer. These roles are being challenged, ironically by new technology, specifically the Internet. The irony of this is that the travel industry has traditionally been a major innovator in the use of technology through their use of computerized reservation systems.
