This chapter explores the possible ontological questions and epistemological propositions that arise from detailed empirical research into cinema closures. Repeated pronouncements of the ‘Death of Cinema’ in the wake of technological, social and industrial change serve to reinforce the coincidence of ‘death’ with a type of ‘closure’. The evocation of a ‘crisis’ in the cinema is ordinarily articulated within the terms of specific cultural concerns around transience and transformation in the social experience of the cinema. However, rather than adding another chapter to the apocalyptic historiography of the cinema this paper proposes instead the constitutive importance of ‘closure’ as a critical tool for rethinking our defining assumptions about cinema(s). Specifically, the chapter will demonstrate how the conceptual granularity entailed in the development of a detailed database of venue openings and closings (the Cinema and Audiences in Australia Project database) can in turn lead to a fundamental reconsideration of the ontology of the cinema itself.

This paper argues that it is essential for live theatre that incorporates stereoscopic imagery to reconceptualise the performance space to facilitate a successful audience experience. While 3D technology greatly increases artistic possibilities, the risks of perceptual confusion exist in live theatre just as in stereoscopic cinema, indeed more so given the coexistence of live performers. This paper argues that Gestalt perceptual organization theory can be valuable in informing how best to employ stereoscopic imagery within a live theater environment, with reference to the artistic works of one of the authors.

Viewpoints are a structural approach to training and directing for theatre. Originating from the innovative, inventive and exploratory approach of Mary Overlie and the self- confessed scavenger approach of Anne Bogart, Viewpoints offers a practical philosophy of working. As a training approach it begins with a disciplined engagement  of the body in space and time. The tangible elements of the Viewpoints provide a set of tasks on which the student can focus, thus freeing the imagination and spirit to  create. Yet at the same time the systematic logic of Viewpoints supports novice practitioners to begin to question their perception, invest in creative practice that demands action and exploration, and to deconstruct, re-organise and rebuild scores and sequences in the pursuit of theatre that is visceral and visual. This essay reports on undergraduate student experiences of learning Viewpoints. It interrogates the demands of embodied learning of the movement/structural system on non- ancers and examines student-actor experiences of embodied learning from multiple of subject positions – observer/participant/creator/reflector/actor.

Body image research with young children has typically examined their body satisfaction and overlooked developmental theories pertaining to their emergent body-knowledge. Though existing research suggests that preschoolers do demonstrate anti-fat attitudes and weight-related stigmatisation, body dissatisfaction can be difficult to assess in preschoolers due to developmental differences in their (i) ability to perceive their actual body size accurately and (ii) make comparisons with a hypothetical ideal. We review current findings on the attitudinal component of body image in preschoolers, together with findings on the accuracy of their body size perceptions and their emergent body awareness abilities. Such an integration of the cognitive development literature is key to identifying when and how young children understand their physical size and shape; this in turn is critical for informing methodological design targeted at assessing body dissatisfaction and anti-fat attitudes in early childhood.

AbstractThe latest Australian Commonwealth Government Close the Gap Report reveals the circumstances of many of Australia’s Indigenous Peoples are either stagnant or going backwards. This paper argues that such ongoing injustice is a consequence of systemic racism that has been perpetuated since colonization and sustained in the twenty first century by discussion or mention of racism being taboo. A counter colonial educational framework is then provided that has the potential to address such institutional racism. The paper begins by providing a definition of systemic racism. Following this there is a brief explanation of the unique geographical context and the racist history of colonization in Australia. The nature of remote communities, the link between traditional law, country and identity will be outlined. Based on readily available sources such as media reports, social media links, and public policy announcements by government the paper then reflects on what has been reported about closure of remote communities in Western Australia. Government policy, announcements and events of the past year will be described and critically discussed in light of the definition of racism provided at the beginning of the article. The proposed framework requires self-reflexivity of organisations and individuals with a particular focus on aspects of sovereignty, healing, re-learning history and starting with a focus on agency instead of deficit. Being guided by this framework has the potential to avoid arbitrarily forcing people from their physical, spiritual and ancestral home, though this is likely to be a long term proposition rather than a quick fix.

 Oleocanthal a virgin olive oil phenolic produces varying intensities of irritation in the oropharanx in individuals and is also a naturally occuring NSAID effective in reducing inflammatory markers and increasing protein synthesis in skeletal muscle cells. There may be a link between the variation in throat sensitivity to oleocanthal and its effects on muscle growth processes and inflammation.

The aim of this study was to evaluate the effect of aerobic exercise on perceptual and cerebro-spinal responses to graded electrocutaneous stimuli. The design comprised 2 x 30 min of cycling exercise at 30% and 70% of peak oxygen consumption (VO2 peak) on separate occasions in a counter-balanced order in 10 healthy participants. Assessment of nociceptive withdrawal reflex threshold (NWR-T), pain threshold (PT), and somatosensory evoked potentials (SEPs) to graded electrocutaneous stimuli were performed before and after exercise. Perceptual magnitude ratings and SEPs were compared at 30%PT, 60%PT, 100%PT before (Pre), 5 min after (Post1), and 15 min after (Post2) aerobic exercise. There was no difference in the NWR-T and the PT following exercise at 30% and 70% of VO2 peak. ANOVA for the perceptual response within pooled electrocutaneous stimuli show a significant main effect for time (F2,18=5.41, P=0.01) but no difference for exercise intensity (F1,9=0.02, P=0.88). Within-subject contrasts reveal trend differences between 30%PT and 100%PT for Pre-Post1 (P=0.09) and Pre-Post2 (P=0.02). ANOVA for the SEPs peak-to-peak signal amplitude (N1-P1) show significant main effect for time (F2,18=4.04, P=0.04) but no difference for exercise intensity (F1,9=1.83, P=0.21). Pairwise comparisons for time reveal differences between Pre-Post1 (P=0.06) and Pre-Post2 (P=0.01). There was a significant interaction for SEPs N1-P1 between exercise intensity and stimulus intensity (F2,18=3.56, P=0.05). These results indicate that aerobic exercise did not increase the electrocutaneous threshold for pain and the NWR-T. Aerobic exercise attenuated perceptual responses to innocuous stimuli and SEPs N1-P1 response to noxious stimuli.

 This thesis provides evidence of central nervous system adaptations as well as reduced exercising haemodynamics and perceptual responses when light-load resistance exercise/training is performed with blood flow restriction. In addition, this type of training appears beneficial in order to target gains in strength and muscle mass in healthy young populations.

Oleocanthal, has been identified as the sole oropharyngeal irritant in virgin olive oil with large individual variation in the perceived intensity of irritation. In this study participants were screened for sensitivity to the oropharyngeal irritation of oleocanthal and bitterness of 6-n-propylthiouracil (PROP), and categorized as hypersensitive (extremely sensitive) or hyposensitive (extremely insensitive). In addition, we determined if a relationship existed between sensitivity to oleocanthal and PROP and dietary intake. Participants (n = 168) took part in the initial screening for irritation to oleocanthal (gLMS range 1.70-70.31). From this sample 87 participants also completed a 4-day diet diary and rated the intensity of oropharyngeal irritation of olive oil and the bitterness of PROP using a gLMS scale. There was large variability in the perceived intensity of irritation from olive oil (gLMS range 4.26-57.15) and the perceived bitterness of PROP (gLMS range 0.0-62.52) with no association between PROP sensitivity and oleocanthal irritation (r = -0.04, p = 0.71). We report no relationship between oleocanthal sensitivity and total energy intake (r = 0.13, p = 0.29), carbohydrate intake (r = 0.12, p = 0.92), protein intake (r = -0.11, p = 0.37), or fat intake (r = 0.14, p = 0.22). There was no association between PROP sensitivity and total energy intake (r = -0.08, p = 0.46), carbohydrate intake (r = 0.12, p = 0.31), protein intake (r = 0.12, p = 0.32), or fat intake (r = -0.08, p = 0.53). We did find a significant negative correlation between PROP sensitivity status and the intake of broccoli (r = -0.24, p< 0.05). In the present study individual variation in sensitivity to the irritation of virgin olive oil or bitterness of PROP was not related to diet with the exception of PROP sensitivity and broccoli intake.

This paper takes up Nikki Santilli’s lament about the scarcity of scholarship on the prose poem in English to analyse two key features of prose poetry: fragmentation and closure. This paper argues that the prose poem’s visual containment within the paragraph form promises a complete narrative while simultaneously subverting this visual cue by offering, instead, gaps and spaces. Such apertures render the prose poem a largely fragmentary form that relies on metonymic metamorphoses to connect to a larger, unnamed frame of reference. In this way, the prose poem is both complete and yet searching for completeness, closed and lacking closure.The prose poem’s reaching outwards to embrace a larger, absent whole connects this literary form to Friedrich Schlegel’s ‘Athenaeum Fragment 206’ and to the Romantic critical fragment more generally. ‘Athenaeum Fragment 206’ has provided this paper with its title, as a metaphorical reading of Schlegel’s igel, or hedgehog, as fragment ‘implies the existence of [a form that suggests] what is outside itself’ (Rosen 1995: 48). The final section of this paper, analyses two prose poems from the University of Canberra’s International Poetry Studies Institute’s Prose Poetry Project. These works by Jen Webb and Carrie Etter are read for their appeal to metonymy in their exploration of time passing and ultimately, death. They demonstrate that prose poetry is both fragmented and open ended in ways very different from lineated poems.
