A community based systems diagram of obesity causes

INTRODUCTION: Application of system thinking to the development, implementation and evaluation of childhood obesity prevention efforts represents the cutting edge of community-based prevention. We report on an approach to developing a system oriented community perspective on the causes of obesity. METHODS: Group model building sessions were conducted in a rural Australian community to address increasing childhood obesity. Stakeholders (n = 12) built a community model that progressed from connection circles to causal loop diagrams using scripts from the system dynamics literature. Participants began this work in identifying change over time in causes and effects of childhood obesity within their community. The initial causal loop diagram was then reviewed and elaborated by 50 community leaders over a full day session. RESULTS: The process created a causal loop diagram representing community perceptions of determinants and causes of obesity. The causal loop diagram can be broken down into four separate domains; social influences; fast food and junk food; participation in sport; and general physical activity. DISCUSSION: This causal loop diagram can provide the basis for community led planning of a prevention response that engages with multiple levels of existing settings and systems.

Integrated system for high quality water recovery and wastewater treatment

This thesis unveils an integrated system that once applied, could standardise and simplify the processes used for high quality water recovery and wastewater treatment. It forsees lower prices of desalinated and recovered water, in a streamlined and more efficient water industry, by departing from today's thinking of conventional wastewater treatment.

Main streams and fine rivers : thinking the aporetics of edge

This paper takes up the question (reframed by Deleuze and Guattari) of where expansion takes place: at the ends or from the centre. Despite the connotations of mediocrity that can be attributed to the term ‘mainstream’, it is possible to rethink what happens at close range as the space of radical openings. Writers can often believe that what is most abnormal or fringe will produce the highest probability of creative ‘event’. The question, however, can be posed – framed by the lineage of deconstruction – whether the key to unlocking any system of totality or closed possibility may lie in a very central (although physically peripheral) location. If, instead of the classical image, expansion may occur from re-imagined ‘middles’ rather than conventional ‘margins’, this reading of where potential can arise may offer a more resilient model than that of fragile peripheries, forever exposed to being amputated from staid centres of status and restricted participation. Drawing on the writings of Deleuze and Guattari, Derrida and Badiou, this paper seeks to unsettle any simplistic approach to the notion of edge, reinscribing it within the repetitiveness of our situations, to argue that right in the middle of the so-called mainstream, there might be the fine rivers of aporia that when encountered in thought can constitutes gates to that which is most radical in writing and other creative practices.

Toward a clinically meaningful taxonomy of violent offenders: the role of anger and thinking styles

 This thesis identified a clinically meaningful three-group classification system of violent offenders utilising patterns of anger and crime-supporting beliefs using a sample of 305 male violent prisoners. The three types demonstrated differential outcomes following completion of a violence intervention program, highlighting the need for interventions more tailored toward treatment needs.
