Exploring Indigenous representations in Australian film and literature for the Australian Curriculum

The Australian Curriculum: English, v.5 (ACARA, 2013) now being implemented in Queensland asks teachers and curriculum designers to incorporate the cross curriculum priority (CCP)of Indigenous issues through Aboriginal and Torres Strait Islander histories and cultures. In the Australian Curriculum English, (AC:E) one way to address this CCP is by including texts by and about Aboriginal and Torres Strait Islander people. With the rise of promising and accomplished young, Indigenous filmmakers such as Ivan Sen, Rachael Perkins, Wayne Blair and Warwick Thornton, this guide focuses on the suitable films for schools implementing the Australian Curriculum in terms of cultural representations. This annotated guide suggests some films suitable for inclusion in classroom study and suggests some companion texts (novels, plays, television series and animations, documentaries, poetry and short stories) that may be studied alongside the films. Some of these are by Indigenous filmmakers and writers, and others features Aboriginal and Torres Strait Island representations in character and/or themes.

If you build it... film studios and the transformative effects of migrating media production

In the years since the release of the film Field of Dreams, the phrase “If you build it, they will come” has become a cliché beloved by journalists, boosters of speculative land developments or remediations and misty-eyed enthusiasts of a host of unlikely schemes. It is one of the articles of faith of the location interest, the coalition of actors motivated to work to attract film business to a particular place. The phrase is full of optimism and potential. It seeks to instill confidence that the construction of production infrastructure like studios and the nourishment of conditions for local service providers will drive the (economic) locomotive and open the (celebrity) stargate. Unfortunately sometimes, it is just a crazy dream.

Effectiveness of cysteine proteases on protein/pigment film removal

Objective: Theaflavin (TF) from the black tea can react to human salivary proline-rich proteins (PRPs) to form stains on exposed dental surfaces. Here, we employed a model of protein/pigment film using TF and dephosphorylated bovine b-casein (Db-CN), which has an extended conformation, similar to that of salivary PRPs, on a sensor surface to assess the efficacy of cysteine proteases (CPs) including papain, stem bromelain, and ficin, on removing TF bound to Db-CN and the control TF readsorption on the residual substrate surfaces was also measured. Methods: The protein/pigment complex film was built by using a quartz crystal microbalance with dissipation (QCM-D). The efficacies of CPs were assessed by Boltzman equation model. The surface details were detected by grazing angle infrared spectroscopy spectra, atomic force microscopy images, and contact angles. Results: The efficacy order of CPs on hydrolyzing protein/pigment complex film is ficin > papain > bromelain. The results from grazing angle infrared spectroscopy spectra, atomic force microscopy images, and contact angles demonstrated that TF bound on the Db- CN was effectively removed by the CPs, and the amount of TF readsorption on both the residual film of the Db-CN/TF and the Db-CN was markedly decreased after hydrolysis. Conclusion: This study indicates the potential application of the CPs for tooth stain removal and suggests that these enzymes are worthy of further investigation for use in oral healthcare.

Graphene-based thin film supercapacitor with graphene oxide as dielectric spacer

Thin film supercapacitors are produced by using electrochemically exfoliated graphene (G) and wet-chemically produced graphene oxide (GO). Either G/GO/G stacked film or sole GO film are sandwiched by two Au films to make devices, where GO is the dielectric spacer. The addition of graphene film for charge storage can increase the capacitance about two times, compared to the simple Au electrode. It is found that the GO film has very high dielectric constant, accounting for the high capacitance of these devices. AC measurements reveal that the relative permittivity of GO is in the order of 104 within the frequency range of 0.1–70 Hz.

Optimal catalyst thickness in titanium dioxide fixed film reactors: Mathematical modelling and experimental validation

The use of immobilised TiO2 for the purification of polluted water streams introduces the necessity to evaluate the effect of mechanisms such as the transport of pollutants from the bulk of the liquid to the catalyst surface and the transport phenomena inside the porous film. Experimental results of the effects of film thickness on the observed reaction rate for both liquid-side and support-side illumination are here compared with the predictions of a one-dimensional mathematical model of the porous photocatalytic slab. Good agreement was observed between the experimentally obtained photodegradation of phenol and its by-products, and the corresponding model predictions. The results have confirmed that an optimal catalyst thickness exists and, for the films employed here, is 5 μm. Furthermore, the modelling results have highlighted the fact that porosity, together with the intrinsic reaction kinetics are the parameters controlling the photocatalytic activity of the film. The former by influencing transport phenomena and light absorption characteristics, the latter by naturally dictating the rate of reaction.

Microstructure of an artificial grain boundary weak link in an YBa2Cu3O(7-δ) thin film grown on a (100)(110), [001]-tilt Y-ZrO2 bicrystal

The microstructure of an artificial grain boundary in an YBa2Cu3O7-δ (YBCO) thin film grown on a (100)(110), [001]-tilt yttria-stabilized-zirconia (YSZ) bicrystal substrate has been studied using transmission electron microscopy (TEM). The orientation relationship between the YBCO film and the YSZ substrate was [001]YBCO∥[001]YSZ and [110]YBCO∥[100]YSZ for each half of the bicrystal film. However, the exact boundary geometry of the bicrystal substrate was not transferred to the film. The substrate boundary was straight while the film boundary was wavy. In several cases there was bending of the lattice confined within a distance of a few basal-plane lattice spacings from the boundary plane and microfaceting. No intergranular secondary phase was observed but about 25% of the boundary was covered by c-axis-tilted YBCO grains and a-axis-oriented grains, both of which were typically adjacent to CuO grains or surrounded by a thin Cu-rich amorphous layer.

An investigation of silver electrodeposition from ionic liquids : influence of atmospheric water uptake on the silver electrodeposition mechanism and film morphology

The electrodeposition of silver from two ionic liquids, 1-butyl-3-methylimidazolium tetrafluoroborate ([BMIm][BF4]) and N-butyl-N-methyl-pyrrolidinium bis(trifluoromethanesulfonyl)imide ([C4mPyr][TFSI]), and an aqueous KNO3 solution on a glassy carbon electrode was undertaken. It was found by cyclic voltammetry that the electrodeposition of silver proceeds through nucleation–growth kinetics. Analysis of chronoamperometric data indicated that the nucleation–growth mechanism is instantaneous at all potentials in the case of [BMIm][BF4] and [C4mPyr][TFSI], and instantaneous at low overpotentials tending to progressive at high overpotentials for KNO3. Significantly, under ambient conditions, the silver electrodeposition mechanism changes to progressive nucleation and growth in [C4mPyr][TFSI], which is attributed to the uptake of atmospheric water in the IL. It was found that these differences in the growth mechanism impact significantly on the morphology of the resultant electrodeposit which is characterised ex situ by scanning electron microscopy and X-ray diffraction.

Probing second harmonic components of pH-sensitive Redox processes in a mesoporous TiO2-Nafion film electrode with Fourier-transformed large-amplitude sinusoidally modulated voltammetry

Electrochemical processes in mesoporous TiO2-Nafion thin films deposited on indium tin oxide (ITO) electrodes are inherently complex and affected by capacitance, Ohmic iR-drop, RC-time constant phenomena, and by potential and pH-dependent conductivity. In this study, large-amplitude sinusoidally modulated voltammetry (LASMV) is employed to provide access to almost purely Faradaic-based current data from second harmonic components, as well as capacitance and potential domain information from the fundamental harmonic for mesoporous TiO2-Nafion film electrodes. The LASMV response has been investigated with and without an immobilized one-electron redox system, ferrocenylmethyltrimethylammonium+. Results clearly demonstrate that the electron transfer associated with the immobilized ferrocene derivative follows two independent pathways i) electron hopping within the Nafion network and ii) conduction through the TiO2 backbone. The pH effect on the voltammetric response for the TiO2 reduction pathway (ii) can be clearly identified in the 2nd harmonic LASMV response with the diffusion controlled ferrocene response (i) acting as a pH independent reference. Application of second harmonic data derived from LASMV measurement, because of the minimal contribution from capacitance currents, may lead to reference-free pH sensing with systems like that found for ferrocene derivatives.

Anodic formation of a thick three-dimensional nanoporous WO3 film and its photocatalytic property

We report an efficient solar-light-driven photocatalyst based on three-dimensional nanoporous tungsten trioxide (WO3) films. These films are obtained by anodizing W foils in fluoride-containing electrolytes at room temperature and under low applied voltages with an efficient growth rate of 2 μm h− 1. The maximum thickness of the films is ~ 3 μm that exceeds those of previously reported anodized WO3 films in fluoride-containing electrolytes. By investigating the photocatalytic properties of the films with thicknesses ranging from ~ 0.5 to ~ 3 μm, the optimum thickness of the nanoporous film is found to be ~ 1 μm, which demonstrates an impressive 120% improvement in the photocatalytic performance compared to that of a RF-sputtered nanotextured film with similar weights. We mainly ascribe this to large surface area and smaller bandgap.

Continuous production of Bi-2212 thick film on silver tape

Bi-2212 thick film on silver tapes are seen as a simple and low cost alternative to high temperature superconducting wires produced by the Powder In Thbe (PIT) technique, particularly in react and wind applications. A rig for the continuous production of Bi-2212 tapes for use in react and wind component manufacture has been developed and commissioned. The rig consists of several sections, each fully automatic, for task specific duties in the production of HTS tape. The major sections are: tape coating, sintering and annealing. High temperature superconducting tapes with engineering critical current densities of 10 kA/cm2 (77 K, self field), and lengths of up to 100 m have been produced using the rig. Properties of the finished tape are discussed and results are presented for current density versus bend radius and applied strain. Depending on tape content and thickness, irreversible strain tirrm varies between 0.04 and 0.1 %. Cyclic bending tests when applied strain does not exceed Eirrm showed negligible reduction in J c along the length of the tape.

Application of texture analysis in tear film surface assessment based on videokeratoscopy

Purpose Videokeratoscopy images can be used for the non-invasive assessment of the tear film. In this work the applicability of an image processing technique, textural-analysis, for the assessment of the tear film in Placido disc images has been investigated. Methods In the presence of tear film thinning/break-up, the reflected pattern from the videokeratoscope is disturbed in the region of tear film disruption. Thus, the Placido pattern carries information about the stability of the underlying tear film. By characterizing the pattern regularity, the tear film quality can be inferred. In this paper, a textural features approach is used to process the Placido images. This method provides a set of texture features from which an estimate of the tear film quality can be obtained. The method is tested for the detection of dry eye in a retrospective dataset from 34 subjects (22-normal and 12-dry eye), with measurements taken under suppressed blinking conditions. Results To assess the capability of each texture-feature to discriminate dry eye from normal subjects, the receiver operating curve (ROC) was calculated and the area under the curve (AUC), specificity and sensitivity extracted. For the different features examined, the AUC value ranged from 0.77 to 0.82, while the sensitivity typically showed values above 0.9 and the specificity showed values around 0.6. Overall, the estimated ROCs indicate that the proposed technique provides good discrimination performance. Conclusions Texture analysis of videokeratoscopy images is applicable to study tear film anomalies in dry eye subjects. The proposed technique appears to have demonstrated its clinical relevance and utility.

Beyond the modular film school : Australian film and television schools and their digital transitions

In this chapter we will describe the contemporary variety of practice-oriented training institutions in Australia. We will examine the different ways in which public and private providers are managing the challenges of digitization and convergence. We will consider the logics governing film education this mix of providers pulls into focus, and we will outline some of the challenges providers face in educating, (re)training, and preparing their graduates for life and work beyond the film school. These challenges highlight questions about the accountabilities and responsibilities of practice-oriented film education institutions. This chapter begins with an introductory section that outlines these logics and questions. It explores some of the tensions and dynamics within the spectrum of issues through which we can understand film schools. The chapter then goes on briefly to describe the multifaceted training landscape in Australia, before profiling the leading public provider, the Australian Film, Television and Radio School (AFTRS), as well as the other leading public providers the Victorian College of the Arts, and the Griffith Film School. It concludes with a short section on film education in primary and secondary schools as the education sector prepares for the implementation of a national curriculum in which ‘media arts’ has a new centrality.

Hexagon platinum Schottky contact with ZnO thin film for hydrogen sensing

This paper reports on the study of the effect on adding total peripheries and sharp edges to the Schottky contact as a hydrogen sensor. Schottky contact was successfully designed and fabricated as hexagon-shape. The contact was integrated together with zinc oxide thin film and tested towards 1% hydrogen gas. Simulations of the design were conducted using COMSOL Multiphysics to observe the electric field characteristic at the contact layer. The simulation results show higher electric field induced at sharp edges with 4.18×104 V/m. Current-voltage characteristic shows 0.27 V voltage shift at 40 μA biased current.

QUT Architecture Film Studio (Aus)

Research Statement: An urban film produced by Luke Harrison Mitchell Benham, Sharlene Anderson, Tristan Clark. RIVE NOIR explores the film noir tradition, shot on location in a dark urban space between high-rises and the river, sheltered by a highway. With an original score and striking cinematography, Rive Noir radically transforms the abandoned river’s edge through the production of an amplified reality ordinarily unseen in the Northbank. The work produced under my supervision was selected to appear in the Expanded Architecture Research Group’s International Architecture Film Festival and Panel Discussion in Sydney: The University of Sydney and Carriageworks Performance Space, 06 November 2011. QUT School of Design research submission was selected alongside exhibits by AA School of Architecture, London; The Bartlett School of Architecture, London; University of The Arts, London; Arrhaus School of Architecture, Denmark; Dublin as a Cinematic City, Ireland; Design Lab Screen Studio, Australia; and Sona Cinecity, The University of Melbourne. The exhibit included not only the screening of the film but the design project that derived from and extended the aesthetics of the urban film. The urban proposal and architectural intervention that followed the film was subsequently published in the Brisbane Times, after the urban proposal won first place in The Future of Brisbane architecture competition, which demonstrates the impact of the research project as a whole. EXPANDED ARCHITECTURE 2011 - 6th November Architecture Film Night + Panel Discussion @ Performance Space CarriageWorks was Sydney's first International Architectural Film Festival. With over 40 architectural films by local and international artists, film makers and architects. It was followed by Panel Discussion of esteemed academics and artists working in the field of architectural film.

The Brisbane Northbank Urban Film Studio : screening of shortlisted films

Research Statement: In this research project film groups of 4-5 students under my direction produced a 3-5 minute urban film that explored the Brisbane Northbank, and which would become the basis for an urban proposal and design of a small film studio for independent filmmakers in the site. The theoretical premise was that a film studio does not simply produce movies, it creates urban effects all around it and acts as a vortex of cultural activity and social life. For this modest facility where the cinema goes out into the street, the city itself becomes the studio. Students were called to observe the historical problematics of technique, image and effect that arise in the cinema, and to apply these to their own urban-film practice. A panel of judges working in film and architecture shortlisted the 12 best films in 2010 and a major public film screening event took place at the Tribal Cinema. The Shortlisted films today form a permanent "exhibit" in YouTube. The research project was funded by the Queensland University of Technology, School of Design and received accolades from film faculty in the Creative Industries Faculty. The diverse body of work that emanated from the screening contributed a unique analysis of the Northbank to Brisbane.
