Social Work and a New Social Order - Challenging Neo-liberalism's Erosion of Solidarity

The world in which social work operates today is a very different world from that in which most of us took their social work training, and the changes we are facing are profound. This paper argues that these changes are not merely a regime change in social policy but that they are essentially about a re-ordering of social relationships and attempt to model them on neo-liberal ideas. In view of these pressures it is understandable that social workers often try to ignore those changes and withdraw into a private world of therapeutic relationships in which the methods they trained in are made to be still valid, or they simply go along with new service delivery designs without asking too many questions. Both reactions fail to question what the "social" can still mean in the light of these changes and how social workers can fulfil their mandate to be responsible for the social dimension of public life. Nothing less than a head-on challenge of the basic presuppositions of neo-liberalism (Willke 2003) and their manifold applications to social service delivery systems will thereby suffice.

Simulating Wind and Warmth in Virtual Reality: Conception, Realization and Evaluation for a CAVE Environment

Wind and warmth sensations proved to be able to enhance users' state of presence in Virtual Reality applications. Still, only few projects deal with their detailed effect on the user and general ways of implementing such stimuli. This work tries to fill this gap: After analyzing requirements for hardware and software concerning wind and warmth simulations, a hardware and also a software setup for the application in a CAVE environment is proposed. The setup is evaluated with regard to technical details and requirements, but also - in the form of a pilot study - in view of user experience and presence. Our setup proved to comply with the requirements and leads to satisfactory results. To our knowledge, the low cost simulation system (approx. 2200 Euro) presented here is one of the most extensive, most flexible and best evaluated systems for creating wind and warmth stimuli in CAVE-based VR applications.
