The third space: The poetry of Sudesh Mishra & the paintings of John Forrest

This book consists of two chapters that document and analyse the context and development of a collaboration between two writers, a poet and a painter, 33 poems and 33 paintings. The poems and paintings are placed in a dialogical relationship with each other. The book attempts to do more than present poetry and paintings serving merely as an illustration of each other. Instead the authors/artists have experimented with how each art-form can bring further significance to another and make new meaning. The two chapters and introduction set up for the viewer a means of exploring a novel form of making meaning. Furthermore these chapters discuss aesthetic, philosophical, historical and political questions endemic not only to the selected art and poetry but to questions governing creative art processes. In this sense it deals with what we have termed 'a third space'.

Resistance and resilience: Can the abrupt end of extreme drought reverse avifaunal collapse?

Aim: Climate change is expected to increase the frequency and intensity of extreme climatic events, such as severe droughts and intense rainfall periods. We explored how the avifauna of a highly modified region responded to a 13-year drought (the 'Big Dry'), followed by a two-year period of substantially higher than average rainfall (the 'Big Wet'). Location: Temperate woodlands in north central Victoria, Australia. Methods: We used two spatially extensive, long-term survey programmes, each of which was repeated three times: early and late in the Big Dry, and in the Big Wet. We compared species-specific changes in reporting rates between periods in both programmes to explore the resistance (the ability to persist during drought) and resilience (extent of recovery post-drought) of species to climate extremes. Results: There was a substantial decline in the reporting rates of 42-62% (depending on programme) of species between surveys conducted early and late in the Big Dry. In the Big Wet, there was some recovery, with 21-29% of species increasing substantially. However, more than half of species did not recover and 14-27% of species continued to decline in reporting rate compared with early on in the Big Dry. Species' responses were not strongly related to ecological traits. Species resistance to the drought was inversely related to resilience in the Big Wet for 20-35% of the species, while 76-78% of species with low resistance showed an overall decline across the study period. Conclusions: As declines occurred largely irrespective of ecological traits, this suggests a widespread mechanism is responsible. Species that declined the most during the Big Dry did not necessarily show the greatest recoveries. In already much modified regions, climate extremes such as extended drought will induce on-going changes in the biota. © 2014 John Wiley & Sons Ltd.

The films of John Hughes: a history of independent screen production in Australia

ABSTRACTIn The Films of John Hughes: A history of independent screen production in Australia filmmaker and academic John Cumming tells the ongoing story of Hughes’ work illustrating the delicate balance of individual, collective and corporate agendas that many contemporary artists need to negotiate. This story begins in the 1960s with a generation of intelligent, socially engaged young people who challenge established power structures, conventions and stereotypes in art, politics and the media. Experiments were being made with grassroots democracy, with new social formations and new ways of seeing and communicating. The book also pays attention to earlier periods of cultural and political activism that captured Hughes’ imagination in the 1970s and became the subject of a number of his films over a period of nearly forty years. Through these films Cumming traces the outline of post-war film culture and production in Melbourne from the 1940s and sets this history within the context of international trends in independent filmmaking throughout the 20th Century and into the 21st.The work of an independent filmmaker has always included a great deal more than directing films. Working in an artisanal mode, he or she often performs, or has a hand in, every aspect of craft at the same time as engaging in discussion and organisation around the wider sphere of screen culture and industry. In addition to having proficiency as a producer, photographer, sound recordist, editor, distributor and exhibitor of films, there is research, organisation, lobbying, entrepreneurship and mentoring to be done. As an independent producer-director, John Hughes has engaged in all of these activities – often simultaneously. He is also a scholar, writer, organiser, activist and teacher. As a television bureaucrat he was both eminent and innovative, and through his filmmaking he has become a leading historian of Australian documentary cinema. ‘… that view – that art and politics are inherently at odds – is still lurking around. It is at the heart of cultural conservatism; and John Hughes’s film-making, from the 1970s to the present, confounds its proponents. His cinema is at once crowded, detailed, elegant and absolutely lucid; at the same time, it is shot through with political and historical understandings.’ Sylvia Lawson, ‘Such a Bloody Wonderful Place’, Inside Story, 28 April 2013.

Movement ecology of nomadic arid zone waterfowl

This thesis provides insights into the spatial and temporal patterns of movement in nomadic waterfowl, the response of birds to rapid environmental change, behavioural flexibility of avian movements and the ability of birds to locate seemingly unpredictable water bodies in vast arid landscapes.

An integrative framework for the appraisal of coloration in nature

The world in color presents a dazzling dimension of phenotypic variation. Biological interest in this variation has burgeoned, due to both increased means for quantifying spectral information and heightened appreciation for how animals view the world differently than humans. Effective study of color traits is challenged by how to best quantify visual perception in nonhuman species. This requires consideration of at least visual physiology but ultimately also the neural processes underlying perception. Our knowledge of color perception is founded largely on the principles gained from human psychophysics that have proven generalizable based on comparative studies in select animal models. Appreciation of these principles, their empirical foundation, and the reasonable limits to their applicability is crucial to reaching informed conclusions in color research. In this article, we seek a common intellectual basis for the study of color in nature. We first discuss the key perceptual principles, namely, retinal photoreception, sensory channels, opponent processing, color constancy, and receptor noise. We then draw on this basis to inform an analytical framework driven by the research question in relation to identifiable viewers and visual tasks of interest. Consideration of the limits to perceptual inference guides two primary decisions: first, whether a sensory-based approach is necessary and justified and, second, whether the visual task refers to perceptual distance or discriminability. We outline informed approaches in each situation and discuss key challenges for future progress, focusing particularly on how animals perceive color. Given that animal behavior serves as both the basic unit of psychophysics and the ultimate driver of color ecology/evolution, behavioral data are critical to reconciling knowledge across the schools of color research.

Challenges of diabetes prevention in the real world : results and lessons from the Melbourne diabetes prevention study

OBJECTIVE: To assess effectiveness and implementability of the public health programme Life! Taking action on diabetes in Australian people at risk of developing type 2 diabetes.

RESEARCH DESIGN AND METHODS: Melbourne Diabetes Prevention Study (MDPS) was a unique study assessing effectiveness of Life! that used a randomized controlled trial design. Intervention participants with AUSDRISK score ≥15 received 1 individual and 5 structured 90 min group sessions. Controls received usual care. Outcome measures were obtained for all participants at baseline and 12 months and, additionally, for intervention participants at 3 months. Per protocol set (PPS) and intention to treat (ITT) analyses were performed.

RESULTS: PPS analyses were considered more informative from our study. In PPS analyses, intervention participants significantly improved in weight (-1.13 kg, p=0.016), waist circumference (-1.35 cm, p=0.044), systolic (-5.2 mm Hg, p=0.028) and diastolic blood pressure (-3.2 mm Hg, p=0.030) compared with controls. Based on observed weight change, estimated risk of developing diabetes reduced by 9.6% in the intervention and increased by 3.3% in control participants. Absolute 5-year cardiovascular disease (CVD) risk reduced significantly for intervention participants by 0.97 percentage points from 9.35% (10.4% relative risk reduction). In control participants, the risk increased by 0.11 percentage points (1.3% relative risk increase). The net effect for the change in CVD risk was -1.08 percentage points of absolute risk (p=0.013).

CONCLUSIONS: MDPS effectively reduced the risk of diabetes and CVD, but the intervention effect on weight and waist reduction was modest due to the challenges in recruiting high-risk individuals and the abbreviated intervention.
