Chasing our tails: psychological, institutional and societal paradoxes in natural resource management, sustainability, and climate change in Australia.

Natural Resource Management (NRM) and Ecologically Sustainable Development (ESD) have been guiding frameworks in Australia for a number of decades. Recently, NRM and ESD have become central to climate change mitigation. In this paper, we explore the psychological paradoxes that function within climate change settings, with particular attention devoted to the way that research and development reinforces these paradoxes by advocating for participatory forms of inquiry. Paradox emerges in NRM at psychological, institutional, and organisational levels. Paradoxes are also features of different forms of democracy such as neoliberal and participatory democracy. Although NRM, ESD and climate change are often conceptualised as distinct issue domains, these policy areas are fundamentally interconnected in both theory and in practice. This interconnection between these policy and research settings, reflections on paradox, and the experience of incorporating community psychology into the paradoxical settings of NRM and climate change are captured in this paper.

Fluid film thickness measurement with moiré fringes.

A mathematical analysis of the application of moiré fringe contouring to fluid film thickness measurement is made. Two special cases are treated. The first considers the generation of contours with a collimated light source and distant observer. The second analyzes the fringe patterns viewed by an observer near the grid when there is a point source of light. Geometrical restrictions imposed on the experimental setup are detailed. Experimental results are included.
