The aim of this paper is to generalize the‎‎notion of pseudo-almost valuation domains to arbitrary‎ ‎commutative rings‎. ‎It is shown that the classes of chained rings‎ ‎and pseudo-valuation rings are properly contained in the class of‎ ‎pseudo-almost valuation rings; also the class of pseudo-almost‎ ‎valuation rings is properly contained in the class of quasi-local‎ ‎rings with linearly ordere...

Abstract In the development and deployment of health ageing innovations, underlying values such as privacy or quality life are often seen a relatively stable starting point, if considered at all. However, neither nor singular. This paper introduces valuation framework to explore co-constitution technological innovations. A careful ongoing reflection on valuation, in particular innovation practi...

In the preceding article, Weinstein et al. [1] explain the QALY concept, its methods, and their underlying assumptions. A number of interesting themes for discussion arise from this factual presentation. We restrict ourselves to addressing four issues that we deem particularly challenging. As a general background for our selection of issues, we reiterate a basic point about valuation perspectiv...

BACKGROUND A common feature of most reviews or catalogues of health utilities has been their focus on adult health states or derivation of values from adult populations. More generally, utility measurement in or on behalf of children has been constrained by several methodological concerns. The objective of this study was to conduct the first comprehensive systematic review and meta-analysis of ...

BACKGROUND Previous research to develop a new generic paediatric health-related quality of life (HR-QOL) measure generated 11 dimensions of HR-QOL, covering physical, emotional and social functioning. These dimensions and their response scales were developed from interviews with children. Some of these dimensions have alternative wording choices. The measure is intended to be preference based s...

The present paper reviews activity in environmental valuation by examining trends in publication rates over the past three decades. It also provides an overview of the demand for environmental valuation by academic markets and by policy markets. The results of this historical analysis suggest that there is not as much use of environmental valuation in policy analysis as could be expected given ...
