BACKGROUND AND AIMS To elicit utility values for five health states corresponding to increasing severity of hepatic encephalopathy, from members of the general public in the UK. The health states studied were Conn grades 0, 1, 2, 3 and 4. METHODS Interviewer-administered time trade-off (TTO) and standard gamble (SG) utilities were elicited for the five health states from a random sample of 20...

Abstract We present an algorithm that, given finite diagrams of simplicial sets X , A Y i.e., functors $${\mathcal {I}}^\textrm{op}\rightarrow {\textsf {s}} {Set}}$$ I op → s Set such that (...

OBJECTIVE To outline current approaches to diagnosing and managing delirium in the elderly. QUALITY OF EVIDENCE A literature review was based on a MEDLINE search (1966 to 1998). Selected articles were reviewed and used as the basis for discussion of diagnosis and etiology. We planned to include all published randomized controlled trials regarding management but found only two. Consequently, we ...

The objectives of this study were to identify the major motives underlying an officer's decision to volunteer for the Submarine Service. Responses to the open-ended question "Why are you interested in submarines?" were obtained from two samples of officer candidates for Basic Submarine School (Ns were 59 and 60). Categorization and Q-sorting of this array of responses produced 9 motivation cate...

We propose an extension of the Conn-Index to evaluate fuzzy cluster solutions obtained from fuzzy prototype vector quantization, whereas the original Conn-Index was designed for crisp vector quantization models. The fuzzy index explicitly takes the fuzzy assignments resulting from fuzzy vector quantization into account. This avoids the information loss which would occur if the original crisp in...
