The age related prevalence of aggression and self-injury in persons with an intellectual disability: A review
The aim of this study was to analyse statistically published data regarding the age related prevalence of aggression and self-injury in persons with intellectual disability. Studies including prevalence data for aggression and/or self-injury broken down by age band were identified and relative risk analyses conducted to generate indices of age related change. Despite conflicting results, the analysis conducted on included studies considered to be the most methodologically robust indicated that the relative risk of self-injury, and to a lesser extent aggression, increased with age until mid-adulthood, with some indication of a curvilinear relationship for self-injury. These conclusions have implications for the understanding of the development of different forms of challenging behavior and the importance of early intervention strategies
The relationship between levels of mood, interest and pleasure and "challenging" behaviour in adults with severe and profound intellectual disabilities
Weak solutions to mean curvature flow respecting obstacles I: the graphical case
We consider the problem of evolving hypersurfaces by mean curvature flow in
the presence of obstacles, that is domains which the flow is not allowed to
enter. In this paper, we treat the case of complete graphs and explain how the
approach of M. Saez and the second author yields a global weak solution to the
original problem for general initial data and onesided obstacles.Comment: updated version with minor corrections and 2 new figure
