Deformation spaces Hom(π,G)/G of representations of the fundamental group π of a surface Σ in a Lie group G admit natural actions of the mapping class group ModΣ, preserving a Poisson structure. When G is compact, the actions are ergodic. In contrast if G is noncompact semisimple, the associated deformation space contains open subsets containing the Fricke-Teichmüller space upon which ModΣ acts...

Appropriate awareness support has been an issue in the area of Computer-Supported Cooperative Work (CSCW) for quite a while. Yet, many challenges like the dual trade-off between awareness and privacy and awareness and disruption still remain. In this paper we present our human-centred approach on how to utilise group dynamics and team development specific information patterns to control awarene...

Event-Based Social Networks (EBSNs) such as Meetup, Plancast, etc., have become popular platforms for users to plan and organize social events with friends and acquaintances. These EBSNs provide rich online and offline user interactions, and rich event content information which can be leveraged for personalized group-event recommendations.
