In this paper we propose a theoretical model for quality of life after laryngectomy. By combining findings from literature, relevant factors for determining quality of life are presented. The importance of these factors is exemplified by interviews with laryngectomees. The practical purpose is...

The plurality majority converse (PMC), the strongest possible instance of a plurality majority disagreement, is studied in the context of single peakedness. After sharpening some of the notions of unfolding theory we construct PMCs for the case where all voters' preference orders are single...

We present an algorithm for generating a random weak order of m objects in which all possible weak orders are equally likely. The form of the algorithm suggests analytic expressions for the probability of a Condorcet winner both for linear and for weak preference orders.

This paper shows that QALYs can be derived from more elementary conditions than thought hitherto in the literature: it suffices to impose risk neutrality for life years in every health state. This derivation of QALYs is appealing because it does not require knowledge of concepts from utility...
