This article questions the preconceived notions that participants in virtual worlds are essentially consumers. Building on the existing scholarship around virtual worlds and notwithstanding the current character of virtual worlds, this paper explores aspects of End User Licence Agreements and notes the unfairness of their provisions, particularly the imbalance between user and developer interests governed by such contracts. It argues that the contracts cannot be regulated with consumer protection legislation, as interests such as property or intellectual property are beyond the scope of consumer protection regimes. Finally, recognising the phenomenon of constitutionalisation of virtual worlds, the article argues for stronger regulatory solutions in this domain, in order to strike a more appropriate balance between competing interests in virtual worlds.

This paper establishes a procedure for numerical analysis of a hip joint using the finite volume method. Patient-specific hip joint geometry is segmented directly from computed tomography and magnetic resonance imaging datasets and the resulting bone surfaces are processed into a form suitable for volume meshing. A high resolution continuum tetrahedral mesh has been generated, where a sandwich model approach is adopted; the bones are represented as a stiffer cortical shells surrounding more flexible cancellous cores. Cartilage is included as a uniform thickness extruded layer and the effect of layer thickness is investigated. To realistically position the bones, gait analysis has been performed giving the 3D positions of the bones for the full gait cycle. Three phases of the gait cycle are examined using a finite volume based custom structural contact solver implemented in open-source software OpenFOAM.
