The Interdependence of Sequential Senate Elections: Evidence from 1946-2002

Among U.S. federal elections, Senate elections are unique in that each state is a two-member district where representatives are elected sequentially to overlapping terms. Models of the sequential nature of Senate elections have been proposed suggesting that the outcome of the election for one of the state’s two U.S. Senate seats affects the contest for the other. More specifically, these models...

Galois Connections with Hedges

We introduce (fuzzy) Galois connections with hedges. Fuzzy Galois connections are basic structures behind so-called formal concept analysis of data with fuzzy attributes. Introducing hedges to Galois connections means introducing two parameters. The parameters influence the size of the set of all the fixpoints of a Galois connection. In the sense of formal concept analysis, the fixpoints, calle...

Linguistic Logics with Hedges

Human knowledge is commonly expressed linguistically, i.e., truth of vague sentences is given in linguistic terms, and many hedges are often used simultaneously to state different levels of emphasis. In this paper, we propose an axiomatization of mathematical fuzzy logic with many hedges where each hedge does not have any dual one. Then, we present linguistic logics built based on the proposed ...
