Properties of hand-made clay balls used as a novel filter media

Filtration using granular media such as quarried sand, anthracite and granular activated carbon is a well-known technique used in both water and wastewater treatment. A relatively new prefiltration method called pebble matrix filtration (PMF) technology has been proved effective in treating high turbidity water during heavy rain periods that occur in many parts of the world. Sand and pebbles are the principal filter media used in PMF laboratory and pilot field trials conducted in the UK, Papua New Guinea and Serbia. However during first full-scale trials at a water treatment plant in Sri Lanka in 2008, problems were encountered in sourcing the required uniform size and shape of pebbles due to cost, scarcity and Government regulations on pebble dredging. As an alternative to pebbles, hand-made clay pebbles (balls) were fired in a kiln and their performance evaluated for the sustainability of the PMF system. These clay balls within a filter bed are subjected to stresses due to self-weight and overburden, therefore, it is important that clay balls should be able to withstand these stresses in water saturated conditions. In this paper, experimentally determined physical properties including compression failure load (Uniaxial Compressive Strength) and tensile strength at failure (theoretical) of hand-made clay balls are described. Hand-made clay balls fired between the kiln temperatures of 875oC to 960oC gave failure loads of between 3.0 kN and 7.1 kN. In another test when clay balls were fired to 1250oC the failure load was 35.0 kN compared to natural Scottish cobbles with an average failure load of 29.5 kN. The uniaxial compressive strength of clay balls obtained by experiment has been presented in terms of the tensile yield stress of clay balls. Based on the effective stress principle in soil mechanics, a method for the estimation of maximum theoretical load on clay balls used as filter media is proposed and compared with experimental failure loads.

Training opportunities in public art

Craft practitioners and designers have been involved in the production of civic art commissions for many centuries, either as recognised art workers or anonymous artisans. However, it has only been in the last couple of decades that Australia has formally acknowledged the role of public art through the development of government policy and professional accredited training

Marcel Cousins : every little thing

This review considers the artwork of Melbourne artist Marcel Cousins showed at Ryan Renshaw Gallery, Brisbane in April 2012. The review traces Cousins' doctoral study in Tokyo. It then assesses his paintings and installations that explore the transformation of generic objects in exhibition contexts, as well as the aesthetic dimensions of such processes.

'These are my photos of when I was little' : Locating Media Arts in the Primary School Curriculum

‘Media Arts’ has been included as a fifth area of the Arts for the Australian Curriculum which will become mandatory learning for all Australian children from pre-school to Year Six (Y6) from 2014. The current curriculum design is underpinned by an approach familiar to media educators who combine creative practice and critical response to develop students’ media literacies. Media Arts within the Australian Curriculum will place Australia at the forefront of international efforts to promote media education as an entitlement for all children. Even with this mandated endorsement, however, there remains ongoing debate about where to locate media education in school curricula. Historically, media education in Australia has been approached through diverse curriculum activities at the secondary school level. These include subject English’s critical literacy objectives; vocationally oriented media and technology education or ICTs education; and Arts courses using new media technologies for creativity. In this chapter we consider the possibilities and challenges for Media Arts, specifically for primary school student learning. We draw on empirical evidence from a research project that has trialled a Media Arts curriculum with students attending a primary school in a low socio-economic status and culturally diverse community on the outskirts of Brisbane, Queensland.

Queer theory, media studies and editorial processes in queer student media

Australian queer (GLBTIQ) university student activist media is an important site of self-representation. Community media is a significant site for the development of queer identity, community and a key part of queer politics. This paper reviews my research into queer student media, which is grounded in a queer theoretical perspective. Rob Cover argues that queer theoretical approaches that study media products fail to consider the material contexts that contribute to their construction. I use an ethnographic approach to examine how editors construct queer identity and community in queer student media. My research contributes to queer media scholarship by addressing the gap that Cover identifies, and to the rich scholarship on negotiations of queer community.

Extending the ABC's public service remit through ABC Pool

Historically, the public service broadcaster (PSB) acted beyond its institutional broadcasting remit by initiating and facilitating activities to support cultural infrastructure and national identity (Wilson, Hutchinson and Shea 2010). The recent focus to develop new content delivery platforms and services (Debrett 2010) signifies a semantic shift from the PSB to the public service media (PSM) organisation. The Australian PSM organisation, the Australian Broadcasting Corporation (ABC) has moved beyond the era of ‘online’ publishing to incorporate Web 2.0 technologies to foster new relationships with the audience (Walker 2009) and engage in production activities with participatory cultures (Jenkins 2006). This shift presents opportunities and challenges to traditional media production, the existing editorial policies and governance models, and raises questions around the value of PSM experimental and innovative activities. Further, the incorporation of information communication technologies and participatory cultures challenge the core values of ‘public service’ within PSM. This paper examines ABC Pool (abc.net.au/pool) as a means of extending the ABC’s public service remit by incorporating participatory cultures into the production and governance models of the corporation and critically analyses the public value of such innovative experiments.

It engages with a complex art in an accessible manner, addressing concepts important to the rapidly growing field of creative writing, while maintaining a strong craft emphasis, analysing exemplary models of writing and providing related writing exercises. Written by professional writers and teachers of writing, the chapters deal with specific genres or forms – ranging from the novel to new media – or with significant topics that explore the cutting edge state of creative writing internationally (including creative writing and science, contemporary publishing and new workshop approaches).

Guerrilla research tactics: alternative research methods

This case-study explores alternative and experimental methods of research data acquisition, through an emerging research methodology, ‘Guerrilla Research Tactics’ [GRT]. The premise is that the researcher develops covert tactics for attracting and engaging with research participants. These methods range between simple analogue interventions to physical bespoke artefacts which contain an embedded digital link to a live, interactive data collecting resource, such as an online poll, survey or similar. These artefacts are purposefully placed in environments where the researcher anticipates an encounter and response from the potential research participant. The choice of design and placement of artefacts is specific and intentional. DESCRIPTION: Additional information may include: the outcomes; key factors or principles that contribute to its effectiveness; anticipated impact/evidence of impact. This case-study assesses the application of ‘Guerrilla Research Tactics’ [GRT] Methodology as an alternative, engaging and interactive method of data acquisition for higher degree research. Extending Gauntlett’s definition of ‘new creative methods… an alternative to language driven qualitative research methods' (2007), this case-study contributes to the existing body of literature addressing creative and interactive approaches to HDR data collection. The case-study was undertaken with Masters of Architecture and Urban Design research students at QUT, in 2012. Typically students within these creative disciplines view research as a taxing and boring process, distracting them from their studio design focus. An obstacle that many students face, is acquiring data from their intended participant groups. In response to these challenges the authors worked with students to develop creative, fun, and engaging research methods for both the students and their research participants. GRT are influenced by and developed from a combination of participatory action research (Kindon, 2008) and unobtrusive research methods (Kellehear, 1993), to enhance social research. GRT takes un-obtrusive research in a new direction, beyond the typical social research methods. The Masters research students developed alternative methods for acquiring data, which relied on a combination of analogue design interventions and online platforms commonly distributed through social networks. They identified critical issues that required action by the community, and the processes they developed focused on engaging with communities, to propose solutions. Key characteristics shared between both GRT and Guerrilla Activism, are notions of political issues, the unexpected, the unconventional, and being interactive, unique and thought provoking. The trend of Guerrilla Activism has been adapted to: marketing, communication, gardening, craftivism, theatre, poetry, and art. Focusing on the action element and examining elements of current trends within Guerrilla marketing, we believe that GRT can be applied to a range of research areas within various academic disciplines.

Media Literacy through Arts Education in Australia

Media arts has been included as one of five Arts subjects for the new Australian Curriculum and will become mandatory learning for all Australian children from pre-school to year six, and elective for children in years seven to twelve. While media education has historically been associated with English curriculum in Australia, it has also occurred through the Arts since at least the 1960s and creative practice has almost always been included as an aspect of official media curricula. This chapter investigates the possibilities for creative and critical learning enabled through media arts by discussing the media learning of one primary school student. This chapter investigates the possibilities for creative and critical learning enabled through the inclusion of media arts in the curriculum. Media arts has been included as one of five Arts subjects for the new Australian Curriculum and will become mandatory learning for all Australian children from pre-school to year six, and elective for children in years seven to twelve. Media education has historically been associated with English curriculum in Australia due to its development through the critical reading tradition. However, media literacy education in secondary schools has also occurred through the Arts since at least the 1960s and creative practice has almost always been included as an aspect of official media curricula. This chapter investigates the media learning of one primary school student, to consider the nature of creative learning and how this relates to the ‘critical’ aspects of media arts curriculum. We undertook this work as part of a large research project that has been investigating the relationship between digital media and traditional literacy outcomes in a primary school.

Re-targeting choreographic enquiry through motion capture

This creative work is the outcome of preliminary experiments through practice aiming to explore the collaboration of a Dancer/choreographer with an Animator, along with enquiry into the intergeneration of motion capture technologies within the work-flow. The animated visuals derived from the motion capture data is not aimed at just re-targeting of movement from one source to another but looks at describing the thought and emotions of the choreographed dance through visual aesthetics.

Come together : forging publics in Brisbane's Gallery of Modern Art

The Gallery of Modern Art (GoMA) in Brisbane, Australia’s third largest city, recently staged ‘21st Century: Art of the First Decade’. The gallery spaces were replete with a commissioned slide by Carsten Höller, an installation of Rivane Neuenschwande’s I Wish Your Wish (2003), a table of white Legos, a room of purple balloons and other participatory or interactive artworks designed to engage multiple publics and encourage audience participation in a variety of ways. Many of the featured projects used day-to-day experiences and offered new conceptions about art practice and what they can elicit in their public – raise awareness about local issues, help audiences imagine different ways of negotiating their environs or experi-ence a museum in a new way. At times, the bottom floor galleries resembled a theme park – adults and children playing with Legos and using Höller’s slide. This article examines the benefits and limitations of such artistic interventions by relating the GoMA exhibition to Brisbane City Council’s campaign of ‘Together Brisbane’ (featuring images of Neunenschwande’s ribbons); a response to the devastation brought to the city and its surrounds in January 2011. During the Brisbane floods, GoMA’s basement was damaged, the museum closed and upon reopening, visitor numbers soared. In this context, GoMA’s use of engaged art practice – always verging on the ephemeral and ‘fun’ – has been used to project a wider notion of a collective urban public. What questions does this raise, not only regarding the cultural politics around the social and participatory ‘turn’ in art practice, but its use to address a much wider urban public in a moment of crisis.

Enacted Cartography : Formations - 2012 Venice Architecture Biennale

RESEARCH BACKGROUND Enacted Cartography documents 10 years of creative research practice by Ian Weir Research Architect and was developed as standalone exhibition to support Dr Weir’s selection by the Australian Institute of Architects to represent innovative architectural practice via the Institute’s review entitled Formations: New Practices in Australian Architecture – which took the form of an exhibition and book presented in Venice, Italy for 13th International Architecture Exhibition (Venice Architecture Biennale). All works exhibited in Enacted Cartography are original works by Dr Weir and are generated either from or for the remote biodiverse landscapes of the Fitzgerald Bioregion on the south coast of Western Australia. RESEARCH CONTRIBUTION As a creative work in its own right, the Enacted Cartography exhibition makes the following contributions to knowledge: 1. Expands understandings of architectural practice by presenting a geographically-specific but multimodal form of architectural practice - wherein practitioners cross over discipline boundaries into art practice, landscape representation, website design, undergraduate university teaching and community advocacy. 2. Contributes to understandings of how such a diverse multimodal form of practice might be represented through both digital media and traditional print media in an exhibition format. 3. Expands understandings of how architectural practitioners might work within a particular place to develop a geographically-specific sense of identity, a ‘landscape of resistance’. RESEARCH SIGNIFICANCE Enacted Cartography was presented to an international audience during the 13th International Architecture Exhibition (Venice Architecture Biennale). The significance of Dr Weir’s research is evidence by his selected by the Australian Institute of Architects to represent innovation in architectural practice for the Biennale. Enacted Cartography addresses problems of national and international importance including: 1. The sustainable development of biodiverse remote landscapes; 2. The reconciliation of bushfire safety and biodiversity conservation; 3. The necessity for rethinking of architectural design methodologies to meet the complexity of landscape management and design; 4. It challenges orthodox forms of landscape representation (aerial photography, for example) which are demonstrably inadequate registrations of biophysical and cultural landscapes.

Classification—Content Regulation and Convergent Media

On 24 March 2011, Attorney-General Robert McClelland referred the National Classification Scheme to the ALRC and asked it to conduct widespread public consultation across the community and industry. The review considered issues including: existing Commonwealth, State and Territory classification laws the current classification categories contained in the Classification Act, Code and Guidelines the rapid pace of technological change the need to improve classification information available to the community the effect of media on children and the desirability of a strong content and distribution industry in Australia. During the inquiry, the ALRC conducted face-to-face consultations with stakeholders, hosted two online discussion forums, and commissioned pilot community and reference group forums into community attitudes to higher level media content. The ALRC published two consultation documents—an Issues Paper and a Discussion Paper—and invited submissions from the public. The Final Report was tabled in Parliament on 1 March 2012. Recommendations: The report makes 57 recommendations for reform. The net effect of the recommendations would be the establishment of a new National Classification Scheme that: applies consistent rules to content that are sufficiently flexible to be adaptive to technological change; places a regulatory focus on restricting access to adult content, helping to promote cyber-safety and protect children from inappropriate content across media platforms; retains the Classification Board as an independent classification decision maker with an essential role in setting benchmarks; promotes industry co-regulation, encouraging greater industry content classification, with government regulation more directly focused on content of higher community concern; provides for pragmatic regulatory oversight, to meet community expectations and safeguard community standards; reduces the overall regulatory burden on media content industries while ensuring that content obligations are focused on what Australians most expect to be classified; and harmonises classification laws across Australia, for the benefit of consumers and content providers.
