Young and Well CRC: Engaging young people as research partners

This paper presents the outcomes of an international collaboration between researchers and young people in Australia and the United States, using participatory design to engage young people as research partners in the collaborative development of a conceptual framework for the Online WellBeing Center (OWBC), a repository of evidence-based mental health tools focused on mental health promotion and the prevention of mental illness developed as part of Young and Well Cooperative Research Centre. Eighteen participants (nine in Australia and nine in USA) were involved as key partners through a series of participatory design workshops to develop the framework for the OWBC. Key objectives of the collaboration included an increased understanding of: how to recruit young people to be part of an international project team collaborating remotely; how to use new technologies to manage communication and maintain engagement; how to apply principles of participatory research to create a youth informed research project; how to develop an international stakeholder partnership to ensure relevancy in value systems, cultural orientation and project outcomes. Recommendations included guidelines for how others can establish international collaborations that integrate young people as active project participants.

Considering research enquiry into biophilic urbanism and office worker productivity

In cities, people spend a significant portion of their time indoors, much of which is in office buildings. The quality and nature of these spaces have the potential to be a strong determinant of people’s health and wellbeing. There is a body of evidence that suggests experiences of nature increase the rate of attention recovery, reduce stress, depression and anxiety, and increase cognitive abilities. Further, the presence of nature inside buildings (such as pot plants and internal green walls) can improve indoor air quality, potentially reducing illness and increasing cognitive function. Urban design that integrates nature into the built environment to provide these benefits, among others, is called ‘biophilic urbanism’ and is the subject of growing international interest and research. The potential for these benefits to increase worker productivity in office buildings is of particular interest, as this could significantly increase the financial performance of office building-based organisations. However, productivity is a complex concept that is difficult to define, and affected by a multitude of factors, which make it difficult to measure. This inability to quantify productivity increases from investments in nature- experiences in office buildings is currently a significant barrier to such investments. Within this context, this paper considers opportunities for research to explore the relationship between office-based nature experiences and productivity, by reviewing existing research in this field and reflecting on the authors’ own experiences. This review has a particular focus on the importance of quantifying this link in order to encourage private property owners to voluntarily integrate nature into buildings to provide city-wide ecosystem service benefits. The paper begins with a contextual overview of how biophilic urbanism can potentially increase worker productivity. Existing methods of measuring and evaluating the performance of biophilic urbanism within the context of office buildings are then explored, along with a discussion of issues with such methods that are currently limiting investment in biophilic urbanism to increase worker productivity and wellbeing. This includes a summary of a survey within a Perth office building to explore the impact of views of nature through a window. Drawing on these insights, the paper makes recommendations regarding opportunities for focusing future investigations to enhance understanding of how biophilic urbanism can contribute to increased wellbeing and productivity in office buildings. This paper builds on work conducted as part of the Sustainable Built Environment National Research Centre Project 1.5, Harnessing the Potential of Biophilic Urbanism in Australia, which considered the role of nature integrated into the built environment in responding to emerging challenges of climate change, resource shortages and population pressures, while providing a host of co- benefits to a range of stakeholders.

What’s Mime got to do with it?

What has Mime got to do with Corporate Communication? As a professional Mime artist on both stage and screen for more than 25 years, the author has been adapting and applying the techniques of Mime to the corporate communication context over a number of years, coaching corporate CEO’s, Executives and Managers, representing both public and private sector corporations and organisations. This unusual inter-contextual skill transfer is the subject of both a book and series of VODCasts by the author (currently in the final stages of completion), which form part of the author’s Doctoral Research and from which this paper is substantially drawn. The author’s professional background is multi-disciplinary – encompassing theatre, television, media, music, tertiary education and corporate training contexts. It is also inter-disciplinary – concerned with the commonality of different artistic mediums and forms and how, where and why these professional disciplines: intersect; interact, and inform each other – and therefore how they support each other - rather than losing creative/professional opportunities because of areas where they might conflict. This paper examines in particular the physicality of presentation and communication – beyond ‘generic’ body-language analysis. It involves the analysis, manipulation and stylisation of human physicality to support and enhance individual inter-professional communication, and how mime performance skills specifically, inform that process. This paper discusses:- • how mime skills clarify and enhance inter-professional communication. • what adaptations need to be applied in that context • getting a ‘performance’ from ‘non-performers’

Blind Collaboration

This paper examines the creation, development and implementation of an artistic process termed by the author ‘Blind Collaboration’. The process involves musicians collaborating on an album of contemporary music where they, the collaborators, do not see or hear each other nor record in the same studio at the same time as their fellow musicians. The notion of musicians recording separately or indeed remotely is not new, however what is new is the ‘blind’ aspect of the process. Each musician is completely unaware of any others’ contributions, and is therefore uninfluenced by what the others might play. None of the musicians hears the overall result until the final mix. The principal focus of this case study lies in the analysis of specific aspects and outcomes of the creative/artistic process - how it evolved, how it was managed, how it was influenced by the particular artists involved and how the Blind Collaboration process ultimately shaped the final musical work.

Implication of calcium hydroxide in the seawater neutralisation of bauxite refinery liquors

Tricalcium aluminate, hydrocalumite and residual lime have been identified as reversion contributing compounds after the seawater neutralisation of bauxite refinery residues. The formation of these compounds during the neutralisation process is dependent on the concentration of residual lime, pH and aluminate concentrations in the residue slurry. Therefore, the effect of calcium hydroxide (CaOH2) in bauxite refinery liquors was analysed and the degree of reversion monitored. This investigation found that the dissolution of tricalcium aluminate, hydrocalumite and CaOH2 caused reversion and continued to increase the pH of the neutralised residue until a state of equilibrium was reached at a solution pH of 10.5. The dissolution mechanism for each compound has been described and used to demonstrate the implications that this has on reversion in seawater neutralised Bayer liquor. This investigation describes the limiting factors for the dissolution and formation of these trigger compounds as well as confirming the formation of Bayer hydrotalcite (mixture of Mg6Al2(OH)16(CO32-,SO42-)•xH2O and Mg8Al2(OH)12(CO32-,SO42-)•xH2O) as the primary mechanism for reducing reversion during the neutralisation process. This knowledge then allowed for a simple but effective method (addition of magnesium chloride or increased seawater to Bayer liquor ratio) to be devised to reduce reversion occurring after the neutralisation of Bayer liquors. Both methods utilise the formation of Bayer hydrotalcite to permanently (stable in neutralised residue) remove hydroxyl (OH-) and aluminate (Al(OH)4-) ions from solution.

Cybercrime attribution : an Eastern European case study

Phishing and related cybercrime is responsible for billions of dollars in losses annually. Gartner reported more than 5 million U.S. consumers lost money to phishing attacks in the 12 months ending in September 2008 (Gartner 2009). This paper asks whether the majority of organised phishing and related cybercrime originates in Eastern Europe rather than elsewhere such as China or the USA. The Russian “Mafiya” in particular has been popularised by the media and entertainment industries to the point where it can be hard to separate fact from fiction but we have endeavoured to look critically at the information available on this area to produce a survey. We take a particular focus on cybercrime from an Australian perspective, as Australia was one of the first places where Phishing attacks against Internet banks were seen. It is suspected these attacks came from Ukrainian spammers. The survey is built from case studies both where individuals from Eastern Europe have been charged with related crimes or unsolved cases where there is some nexus to Eastern Europe. It also uses some earlier work done looking at those early Phishing attacks, archival analysis of Phishing attacks in July 2006 and new work looking at correlation between the Corruption Perception Index, Internet penetration and tertiary education in Russia and the Ukraine. The value of this work is to inform and educate those charged with responding to cybercrime where a large part of the problem originates and try to understand why.

AISC '11 Proceedings of the Ninth Australasian Information Security Conference

The Australasian Information Security Conference (AISC) 2011 was held on 18th-19th January 2011 in Perth, Australia, as a part of the Australasian Computer Science Week 2011. AISC grew out of the Australasian Information Security Workshop and officially changed the name to Australasian Information Security Conference in 2008. The main aim of the AISC is to provide a venue for Australasian and other researchers to present their work on all aspects of information security and promote collaboration between academic and industrial researchers working in this area.

Aligning off-balance sheet risk, on-balance sheet risk and audit fees: a PLS path modelling analysis

This study focuses on using the partial least squares (PLS) path modelling methodology in archival auditing research by replicating the data and research questions from prior bank audit fee studies. PLS path modelling allows for inter-correlations among audit fee determinants by establishing latent constructs and multiple relationship paths in one simultaneous PLS path model. Endogeneity concerns about auditor choice can also be addressed with PLS path modelling. With a sample of US bank holding companies for the period 2003-2009, we examine the associations among on-balance sheet financial risks, off-balance sheet risks and audit fees, and also address the pervasive client size effect, and the effect of the self-selection of auditors. The results endorse the dominating effect of size on audit fees, both directly and indirectly via its impacts on other audit fee determinants. By simultaneously considering the self-selection of auditors, we still find audit fee premiums on Big N auditors, which is the second important factor on audit fee determination. On-balance-sheet financial risk measures in terms of capital adequacy, loan composition, earnings and asset quality performance have positive impacts on audit fees. After allowing for the positive influence of on-balance sheet financial risks and entity size on off-balance sheet risk, the off-balance sheet risk measure, SECRISK, is still positively associated with bank audit fees, both before and after the onset of the financial crisis. The consistent results from this study compared with prior literature provide supporting evidence and enhance confidence on the application of this new research technique in archival accounting studies.

Nano and ultrafine particle number concentrations in different environments : application towards air quality regulations

Particle number concentrations vary significantly with environment and, in this study, we attempt to assess the significance of these differences. Towards this aim, we reviewed 85 papers that have reported particle number concentrations levels at 126 sites covering different environments. We grouped the results into eight categories according to measurement location including: road tunnel, on-road, road-side, street canyon, urban, urban background, rural, and clean background. From these reports, the overall median number concentration for each of the eight site categories was calculated. The eight location categories may be classified into four distinct groups. The mean median particle number locations for these four types were found to be statistically different from each other. Rural and clean background sites had the lowest concentrations of about 3x103 cm-3. Urban and urban background sites showed concentrations that were three times higher (9x103 cm-3). The mean concentration for the street canyon, roadside and on-road measurement sites was 4.6x104 cm-3, while the highest concentrations were observed in the road tunnels (8.6x104 cm-3). This variation is important when assessing human exposure-response for which there is very little data available, making it difficult to develop health guidelines, a basis for national regulations. Our analyses shows that the current levels in environments affected by vehicle emissions are 3 to 28 times higher than in the natural environments. At present, there is no threshold level in response to exposure to ultrafine particles. Therefore, future control and management strategies should target a decrease of these particles in urban environments by more than one order of magnitude to bring them down to the natural background. At present there is a long way to go to achieve this.

Little boxes : changing perceptions and including young people in socially sustainable participatory planning

In recent years, a great deal has been written about the benefits and ethics of including young people in participative decision-making. This has been accompanied by a burgeoning interest in including their views in participatory planning exercises that has not always been realised in practice. Drawing on a detailed analysis of the perceptions of adults and young people involved in a participatory planning exercise on Australia‟s Gold Coast, we believe that there are two major hurdles to the „full‟ engagement of young people that are in some respects two sides of the same coin: the sometimes paternalistic perceptions and often dismissive attitude that many adults have towards the participation of young people; and the perceptions that young people may have of themselves and their subordinate place in an adult-dominated planning environment. Together, such views act to place limitations on the participation of young people because they set up unrealistic expectations for both adult and younger participants in terms of how and why young people participate, and what this participation should „look and feel‟ like. In this paper, through the metaphor of boxes, we propose a number of issues that should be addressed when involving young people in participatory planning processes to ensure the most from their participation for all involved.

Deadly Choices : better ways of doing health promotion

Editor's introduction: Mainstream health promotion has failed Aboriginal and Torres Strait Islander peoples, according to Karen McPhail-Bell, a PhD candidate at Queensland University of Technology. In the article below, she argues that those working in the field could learn from strengths-based programs like The Institute for Urban Indigenous Health’s Deadly Choices. It offers lessons for all health promotion practice, she says. Her challenge is timely, with the Public Health Association of Australia’s 43rd annual conference starting in Perth tomorrow (follow #PHAA2014 for Twitter news from the conference).

Integrating PV systems into distribution networks with battery energy storage systems

Integrating Photovoltaic (PV) systems with battery energy storage in the distribution network will be essential to allow for continued uptake of domestic PV system installations. With increasing concerns regarding environmental and climate change issues, incorporating sources of renewable energy into power networks across the world will be key for a sustainable future. Australia is well placed to utilise solar energy as a significant component of its future energy generation and within the last 5 years there has been a rapid growth in the penetration levels seen by the grid. This growth of PV systems is causing a number of issues including intermittency of supply, negative power flow and voltage rises. Using the simulator tool GridLAB-D with a model of a typical South-East Queensland (SEQ) 11 kV distribution feeder, the effect of various configurations of PV systems have been offset with Battery Energy Storage Systems (BESS). From this, combinations of PV and storage that are most effective at mitigating the issues were explored.

Automated power semiconductor switching performance feature extraction from experimental double-pulse waveform data

Double-pulse tests are commonly used as a method for assessing the switching performance of power semiconductor switches in a clamped inductive switching application. Data generated from these tests are typically in the form of sampled waveform data captured using an oscilloscope. In cases where it is of interest to explore a multi-dimensional parameter space and corresponding result space it is necessary to reduce the data into key performance metrics via feature extraction. This paper presents techniques for the extraction of switching performance metrics from sampled double-pulse waveform data. The reported techniques are applied to experimental data from characterisation of a cascode gate drive circuit applied to power MOSFETs.

Donald Ezekiel AM : passionate and innovative contact lens practitioner and manufacturer

Donald Ezekiel (known to all as ‘Don’) was born in Singapore on September 12, 1936, to a German mother and Iraqi father. His parents were Jewish refugees, who met in Batavia,1 married and alternately lived in Batavia and Singapore. The family established their primary residence in Singapore after Don’s older brother Eric (later to become a haematologist) was born in 1934. The Ezekiel family was forced to flee in 1941 when the Japanese bombed Singapore and were fortunate to obtain passage on a hospital ship to Perth. They returned to Singapore after the war but left again on their own accord in 1951 due to race riots. The Ezekiels sold up everything in Singapore and decided to settle in Perth...
