Engaging educated islands: an examination of the collaborative process of creating the 2009 Venice Biennale art education resource for Australian school students
This paper describes the process of creating an electronic national art education resource based on the 2009 Venice Biennale for K-12 students throughout Australia. Australian artists have been consistently represented for over thirty years at the Venice Biennale with the support of the
Australia Council, the Australian Government's premier art and advisory body. The collaborative process of creating the national art education resource is based on Community Cultural Development (CCD) practices advocated by the Australia Council. This process has brought together a range of people from the field of art education under the CCD guiding principles of: self-determination, sustainability, access, diversity and cultural democracy. This paper will describe the journey of three researchers
involved in the process of creating the resource and how they experienced and engaged with the guiding principles of community cultural development. In addition it will examine the aims of this resource in providing young people with electronic access to a diverse range of Australian artists and their practices and in the process creating a site for critical and reflective engagement concerning a range of contemporary issues such as increased awareness of environmental issues
Respiratory mechanics in ventilated preterm infants : early determinants and outcome
The studies in this thesis show that in the current surfactant era, the majority of ventilated preterm infants are still suffering from respiratory morbidity and substantial respiratory function abnormalities throughout the early years of life. Since respiratory function testing during mechanical ventilation does have important limitations, certain preparatives have to be made before reliable results can be obtained and patients are not getting extra disturbed. Inborn resistive properties of the respiratory system are important in relation to early neonatal respiratory course as well as subsequent respiratory morbidity and respiratory function during the first year of life. With regard to the first-year respiratory course, inborn resistive properties are more important determinants than degree of prematurity and neonatal lung damage. However, in relation to the development of bronchial hyperresponsiveness during infancy, degree of neonatal parenchymal damage to the lung is most important. Tracking of respiratory function is partially present for the resistive properties of the respiratory system during the early years after birth in preterm ventilated infants
Correction factors for oxygen and flow-rate effects on neonatal Fleisch and Lilly pneumotachometers
Objective: To assess the effects of different oxygen concentrations and flow rates on the measurement errors of neonatal pneumotachometers in heated and unheated situations and to develop correction factors to correct for these effects. Design: Prospective laboratory study. Setting: Outpatient clinic with equipment in a standardized setting. Subjects: Neonatal pneumotachometers. Interventions: In standardized conditions, the tested pneumotachometer was calibrated at a flow rate of 3 L/min with 60% oxygen and was set in series with a closed spirometer system being used as a reference. Different air-flow levels (1-9 L/min) and oxygen concentrations (21-100%) were infused into the closed system with the pneumotachometer and spirometer. Measurements and Main Results: The pneumotachometers were significantly affected by changing oxygen concentrations (p < .01) and increasing flow rates (p < .01), increasing the actually measured flow rate. Correction factors, developed by multiple regression analysis, significantly reduced the overall maximum errors of the pneumotachometers from -1.1 to 0.6 L/min to -0.5 to 0.4 L/min. Conclusions: The effects of changes in oxygen concentrations and flow rates on neonatal pneumotachometers could be considerably decreased by the use of correction factors such as were calculated in this study. This will preclude frequent calibration procedures with actual flow and oxygen levels during changes in experimental settings. Copyrigh
Encountering Berlant part 1: Concepts otherwise
In Part 1 of ‘Encountering Berlant’, we encounter the promise and provocation of Lauren Berlant's work. In 1000-word contributions, geographers and others stay with what Berlant's thought offers contemporary human geography. They amplify an encounter with their work, demonstrating how a concept, idea, or style disrupts something, opens up a new possibility, or simply invites thinking otherwise. The encounters range across the incredible body of work Berlant left us with, from the ‘national sentimentality’ trilogy through to recent work on negativity. Varying in form and tone, the encounters exemplify and enact the inexhaustible plenitude of Berlant's thought: fantasy, the case, love, impasse, feel tanks, slow death, ellipses, gesture, attrition, intimate public, ambivalence, style. Part 2 of ‘Encountering Berlant’ focuses on Berlant's most influential concept: ‘cruel optimism’. Across these heterogeneous encounters, Berlant's enduring concern with the tensions and possibilities of relationality and how to enact better forms of common life shine through. These enduring concerns and Berlant's commitment to the incoherence and overdetermination of phenomena are summarised in the Introduction, which also explores how Berlant's work has been engaged with in geography. The result is a repository of what an encounter with Berlant's thought makes possible
Pre-cachexia in patients with stages I-III non-small cell lung cancer: Systemic inflammation and functional impairment without activation of skeletal muscle ubiquitin proteasome system.
AbstractCachexia is a prevalent phenomenon of non-small cell lung cancer (NSCLC) which is responsible for increased mortality and deterioration of physical performance. Preclinical research indicates that systemic inflammation induces cachexia-related muscle wasting through muscular Nuclear Factor-kappa B (NF-κB) signaling and subsequent ubiquitin proteasome system (UPS)-mediated proteolysis. As these pathways could be a target for early intervention strategies, it needs to be elucidated whether increased activation of these pathways is already present in early stage NSCLC cachexia. The aim of the present study was therefore to assess muscular NF-κB and UPS activation in patients with NSCLC pre-cachexia.Sixteen patients with newly diagnosed stages I–III NSCLC having <10% weight loss and ten healthy controls were studied. Body composition, systemic inflammation and exercise capacity were assessed in all subjects and NF-κB and UPS activity in vastus lateralis muscle biopsies in a subset.Patients showed increased plasma levels of C-reactive protein (CRP) (P<0.001), soluble Tumor Necrosis Factor receptor 1 (sTNF-R1) (P<0.05), fibrinogen (P<0.001) and decreased levels of albumin (P<0.001). No changes in fat free body mass or skeletal muscle NF-κB and UPS activity were observed, while peak oxygen consumption (V˙O2 peak) was significantly decreased in patients compared with healthy controls.In conclusion, this exploratory study demonstrates significantly reduced exercise capacity in NSCLC pre-cachexia despite maintenance of muscle mass and unaltered indices of UPS activation. The absence of muscular NF-κB-dependent inflammatory signaling supports the notion that transition of systemic to local inflammation is required to initiate UPS-dependent muscle wasting characteristic for (experimental) cachexia
