This study investigated the factors influencing trust in travel-related CGM and, in turn, the degree to which trust affects the benefits and impacts of using CGM in the course of planning pleasure trips. An online survey of US Internet users was conducted with a total of 1170 individuals responding to questions regarding their perceptions and use of CGM for travel planning. The findings show th...

I develop a multi-country multi-industry model of trade that features heterogeneous consumers with non-homothetic preferences. I use the model to quantify the measurement errors in the welfare gains estimates caused by the assumption of a representative consumer (ARC). First, I reduce the world level of all trade costs by 15% and find that ARC overestimates (underestimates) the gains of the poo...

This paper describes a method for learner modelling for use within simulation-based learning environments. The goal of the learner modelling system is to provide the learner with advice on discovery learning. The system analyzes the evidence that a learner has generated for a specific hypothesis, assesses whether the learner needs support on the discovery process, and the nature of that support...

As a response to a number of notable contemporary aesthetic tendencies, this paper introduces the notion of an infrainstrument as a kind of ‘new interface for musical expression’ worthy of study and systematic design. In contrast to hyper-, metaand virtual instruments, we propose infra-instruments as devices of restricted interactive potential, with little sensor enhancement, which engender sim...

This paper describes one approach for calculating the cohomology of a particular complex which arises in knot theory and which is used to prove the existence of ‘associators’, a key ingredient in the construction of a universal knot invariant. The approach taken is to show that the relevant complex can be interpreted, essentially, as the cohomology of the functor Hom(K, C), where C is the coalg...
