Department of Applied Mathematics and Theoretical Physics, University of Cambridge, Silver Street, Cambridge CB3 9EW, U.K. (9th August, 1999; revised 10th February, 2000) No physical measurement can be performed with infinite precision. This leaves a loophole in the standard no-go arguments against non-contextual hidden variables. All such arguments rely on choosing special sets of quantum-mech...

Common models of social preferences usually assume the existence of a preference for other-regarding behavior / equal sharing. And, apart from this preference being potentially idiosyncratic in strength, qualifications are at most made informally on conferences when empirical deviations from predictions are explained by contextual variables. Starting from this observation, we present a simple f...

BACKGROUND We examined independent influences of contextual variables on cardiovascular risk factors in Shilin county, Yunnan province, South-west China. METHODS Three villages were selected from each of the ten townships based on probability proportional to size. In each selected village, 200 individuals aged > or = 45 years were chosen based on simple random sampling method. From 6006 indiv...

BACKGROUND Investigate the individual and contextual variables related to caries in underprivileged adolescents, and the disparity in distribution of the disease. METHODS Cross-sectional analytical study, conducted in the city of Piracicaba, SP, Brazil, in 2012. The probabilistic sample was composed of 1,179 adolescents from 15-19 years of age, randomly selected from 21 state schools and 34 P...

Understanding the effects of operational conditions and practices on productive efficiency can provide valuable economic and managerial insights. The conventional approach is to use a twostage method where the efficiency estimates are regressed on contextual variables representing the operational conditions. The main problem of the two-stage approach is that it ignores the correlations between ...

In recent years, research into user centric and personalized applications has focused on the utilization of contextual information about the situation in which the user is consuming the content item. However, there is no database suitable for the investigation of specific open issues of contextual information description and utilization available today. The reason for this are several known dif...
