Diminutive Catastrophe: Clown's Play, Margaret J. Phillips

Research outputs 2013

Clowns can be seen as enacting catastrophe with a small “c.” They are experts in “failing better” who perhaps live on the cusp of turning catastrophe into a metaphorical whirlwind while ameliorating the devastation that lies therein. They also have the propensity to succumb to the devastation, masking their own sense of the void with the gestures of play. In this paper, knowledge about clowns emerges from my experience, working with circus clowns in Circus Knie (Switzerland) and Circo Tihany (South America), observing performances and films about clowns, and reading, primarily in European fiction, of clowns in multiple guises. The …

Digital Representation Of Visual Artworks For High-Stakes Assessment, Christopher P. Newhouse

Research outputs 2013

The collection and marking of student artwork across a large jurisdiction such as Western Australia is challenging where the work is submitted to a central location to be marked by experts and returned to students. An alternative approach would be to submit digital representations of the artworks online for marking. However, to give a valid and reliable measure the representations would need to be of adequate quality. Further, judgements of artworks are necessarily subjective giving concern about the reliability of marking for high-stakes assessment. The comparative pairs method of marking lends itself to addressing this problem and is feasible where …

Energy Efficiency Performance Improvements For Ant-Based Routing Algorithm In Wireless Sensor Networks, A. M. Zungeru, Kah Phooi Seng, Li-Minn Ang, W.C. Chia

Research outputs 2013

The main problem for event gathering in wireless sensor networks (WSNs) is the restricted communication range for each node. Due to the restricted communication range and high network density, event forwarding in WSNs is very challenging and requires multihop data forwarding. Currently, the energy-efficient ant based routing (EEABR) algorithm, based on the ant colony optimization (ACO) metaheuristic, is one of the state-of-the-art energy-aware routing protocols. In this paper, we propose three improvements to the EEABR algorithm to further improve its energy efficiency. The improvements to the original EEABR are based on the following: (1) a new scheme to intelligently initialize …

Self-Assessment Of Employability Skill Outcomes Among Undergraduates And Alignment With Academic Ratings, Denise Jackson

Research outputs 2013

Despite acknowledgement of the benefits of self-assessment in higher education, disparity between student and academic assessments, with associated trends in over- and underrating, plagues its meaningful use, particularly as a tool for formal assessment. This study examines self-assessment of capabilities in certain employability skills in more than 1000 Australian business undergraduates. It evaluates the extent to which student self-assessments differ from academics, in what ways and the influence of certain individual and background characteristics - such as stage of degree, gender and academic ability - on rating accuracy. Explanations for documented disparities are presented, in addition to implications and strategies …

Unidirectional Coupling Of Surface Plasmons With Ultra-Broadband And Wide-Angle Efficiency: Potential Applications In Sensing, Kun Li, Feng Xiao, Fan Lu, Kamal Alameh, Anshi Xu

Research outputs 2013

A cascaded-grating coupling scheme for unidirectionally coupling and launching surface plasmons from free-space light with ultra-broadband and wide-angle efficiency is proposed and theoretically investigated, and the potential applications in sensing are discussed. The cascaded sub-gratings of different periods couple the incident light over a relatively wide wavelength and angular range into surface plasmon polaritons (SPPs). After traveling a short distance, the SPPs interact with the sensed medium, and then are coupled back into freely propagating light through the nanoslit in the metal film. By observing the changes of SPP-mediated light coupled out through the slit, broadband sensing is achieved. A …

Toward A Phen(Omen)Ology Of The Seasons: The Emergence Of The Indigenous Weather Knowledge Project (Iwkp), John Charles Ryan

Research outputs 2013

Since European settlement, the Western calendar has insufficiently accounted for the seasonal nuances and multiple temporalities of Australia. Beginning with Tim Entwistle’s recent proposal to revise the four-season Australian norm, this article traces the emergence of the Western calendar in Europe and its institutionalization ‘Down Under.’ With its emphasis on land-based calendars, the Indigenous Weather Knowledge Project (IWKP) is a partnership between Aboriginal communities and the Bureau of Meteorology aimed at preserving and promoting knowledge of the endemic seasons of Australian regions. As the most recent addition to the IWKP, the six-season Nyoongar calendar of the South-West of Western Australia …

Could On-The-Job Embeddedness Help Bind Fifo Workers To Their Jobs?, Glenda B. Scott, Helen B. Sitlington, Pattanee Susomrith, Alan R. Brown

Research outputs 2013

Fly-In Fly-Out (FIFO) employees in the mining industry in Western Australia have had high levels of turnover, resulting in high costs in recruitment, training and lost production. This research is seeking to understand the reasons for high turnover in this somewhat unusual group of employees. Whilst the research has utilised the more traditional approach to understanding labour turnover, that is that dissatisfaction with job or company and the availability of viable alternatives lead to intention to quit, preliminary results indicate that job embeddedness theory, may provide a better understanding of why FIFO workers choose to stay in their jobs. This …

Keys From The Past: Unlocking The Power Of Eighteenth-Century Contrapuntal Pedagogies, Jonathan R. Paget, Stewart J. Smith

Research outputs 2013

How did eighteenth-century musicians learn to compose, and how were they able to produce musical works with such comparative ease and fluency? What were the strategies at play that enabled even the most workman-like of composers to produce vast amounts of competent music, and how was it possible for almost any professional keyboard player to improvise a passable fugue? It is only recently that scholars have sought the answers to such questions. Groundbreaking work by Gjerdigen (1988; 2007a), Porter (2000; 2002), Renwick (1995), and others, provides a fascinating glimpse of the working methods of eighteenth-century musicians, and also offers implications …

Millennial Scale Impact On The Marine Biogeochemical Cycle Of Mercury From Early Mining On The Iberian Peninsula, Oscar Serrano Gras, A. Martinez-Cortizas, M. A. Mateo, H. Biester, R. Bindler

Research outputs 2013

The high-resolution mercury record of a Posidonia oceanica mat in the northwest Mediterranean provides an unprecedented testimony of changes in environmental mercury (Hg) loading to the coastal marine environment over the past 4315 yr BP. The period reconstructed made it possible to establish tentative preanthropogenic background Hg levels for the area (6.8!1.5 ng g–1 in bulk sediments). A small, but significant, anthropogenic Hg increase was identifiable by ~2500 yr BP, in agreement with the beginning of intense mining in Spain. Changes in the record suggest four major periods of anthropogenic Hg pollution inputs to the Mediterranean: first, during the Roman …

Developing Social Skills Through Music: The Impact Of General Classroom Music In An Australian Lower Socio-Economic Area Primary School, John N. Heyworth

Research outputs 2013

Ideas about the physical and psychological healing effects of music date back to the classical Greek period. There is also substantial research concerning the educative influences of music on the human mind. Developmental deficiencies among low socio-economic student populations have often been associated with a reduced sense of self-esteem, responsibility, and ability to form relationships or engage in successful communication. This article describes a pro-active, constructivist approach to music education in a school largely attended by socially and economically disadvantaged students in Australia, and explores the influence of music on social learning. The strategic use of group music lessons in …

Research outputs 2013

This paper traces the consequences of dislocation for studio arts-practice. I recently found myself in Perth, far from my home of 20 years and with directional vertigo, looking east to my old life and west to the Indian Ocean. In order to make sense of this move I used the studio to resolve/recollect/ trace my sense of movement, change, loss and vertigo. The multiple departures and arrivals on this journey are articulated as catalysts to studio production. We rarely speak about the spaces between such departures and arrivals and the effects those spaces have on the lived body. The space …

Tackling Overweight And Obesity: Does The Public Health Message Match The Science?, Katherine Hafekost, David Lawrence, Francis Mitrou, Therese O'Sullivan, Stephen R. Zubrick

Background

Despite the increasing understanding of the mechanisms relating to weight loss and maintenance, there are currently no validated public health interventions that are able to achieve sustained long-term weight loss or to stem the increasing prevalence of obesity in the population. We aimed to examine the models of energy balance underpinning current research about weight-loss intervention from the field of public health, and to determine whether they are consistent with the model provided by basic science. EMBASE was searched for papers published in 2011 on weight-loss interventions. We extracted details of the population, nature of the intervention, and key …

Bio-Inspired Design, Fabrication And Testing Of Bipolar Plates For Pem Fuel Cells, Nannan Guo

Doctoral Dissertations

"The flow field of a bipolar plate distributes reactants for polymer electrolyte membrane (PEM) fuel cells and removes the produced water from the fuel cells. It greatly influences the performance of fuel cells, especially the concentration losses. Two approaches were developed to improve flow field designs in this dissertation. One is inspired by the biological circulatory structures and called bio-inspired designs, which have great potential to transport reactant efficiently and hence improve fuel cell performance. Another way is using a network-based optimization model to optimize the conventional flow field configurations, i.e., pin-type, parallel and serpentine designs, to improve flow distributions …

Polybenzoxazine Aerogels: Synthesis, Characterization, Conversion To Porous Carbons, And Energetic Composites, Shruti Mahadik-Khanolkar

Doctoral Dissertations

"Aerogels are nanoporous, low-density bulk objects, consisting of three-dimensional assemblies of nanoparticle. Structured similarly, polymeric aerogels are emerging as a mechanically strong alternative to traditional silica aerogels, which are fragile. Amongst polymeric aerogels, those based on polybenzoxazine (PBO - a type of phenolic resin), are extremely robust and comprise an economic alternative to resorcinol-formaldehyde aerogels, also a class of phenolic resins, as the main source of carbon aerogels. The drawback of the PBO chemistry has been the long (days) processing time at high-temperatures (>130 ºC). Herewith, we have developed an energy- and time-efficient process to PBO aerogels by inducing …
