It is quite common to see experimental data analysed according to a variety of models of ligand-receptor interaction. Often, parameters derived from such models are compared statistically. The most commonly employed statistical analyses contain explicit assumptions about the underlying distributions of the model parameters being compared, yet the validity(More)
Previous attempts to quantify immersion have been pursued within the context of game virtual worlds where there is a clear outline of a goal. This paper seeks to investigate the problem of immersion measurement in an online based virtual world (ReactionGrid) where there is no distinct in-world goal and environmental context is less immersive as in a game(More)
Educational activities previously performed in Second Life are now more and more move moving to other alternatives. This study concentrates on the features of Second Life and its open-source alternative, OpenSim that affect the results of the in-world educational activities. The need for educators to take these features into account is another focus of this(More)
In this paper we aim to explore the potential advantages of interactions on student engagement and provide guidance to educators who seek interactive and immersive learning experiences for their students through the use of hybrid virtual learning approaches. We define as hybrid virtual learning the educational model where students are co-present and(More)
Virtual worlds can establish a stimulating environment to support a situated learning approach in which students simulate a task within a safe environment. While in previous years Second Life played a major role in providing such a virtual environment, there are now more and more alternative—often OpenSim-based—solutions deployed within the(More)
