Integrated Modelling For Understanding Watershed Development Impacts On Social And Biophysical Systems, Wendy Merritt, V. R. Reddy, K. V. Rao, Paul Pavelic, Shakeel Ahmed, Ram Ranjan, Barry F.W. Croke, Geoffrey J. Syme

Research outputs 2011

The intention of watershed development (WD) programs in India is to improve the livelihoods of people and preserve the natural resource base, particularly in areas where water scarcity limits the development potential of rural communities. In practice, there are many complications to implementing WD programs in an effective and equitable way for all people within and between villages in a catchment. Our understanding of the potential implications of a program is often limited by the way in which we investigate the biophysical-social-economic system. Two common failings are (a) not properly considering the importance of the place, scope and scale of …

Research outputs 2011

We describe the different types of models we used as part of an effort to inform policy-making aiming at the management of the Ningaloo coast in the Gascoyne region, Western Australia. This provides an overview of how these models interact, the different roles they cover, how they fit into a full decision making process and what we learnt about the stakeholders involved in our project via their use. When modelling is explicitly used to address socio-ecological issues, the key determinant of success is whether the models, their results and recommendations are taken up by stakeholders; such uptake in turn depends …

Managing Multidisciplinary Student Design Teams, Martin Masek, Joo Jung, Barnard Clarkson Jan 2011

Managing Multidisciplinary Student Design Teams, Martin Masek, Joo Jung, Barnard Clarkson

Research outputs 2011

The management of multidisciplinary student teams is a challenge. In this paper we describe our experience in running a shared assessment across several units. Four multidisciplinary teams were formed, and success was mixed, with one team splitting into two along discipline lines and all experiencing communication issues. The main management challenges that arose were based around difficulty in communication and the understanding of the other disciplines requirements. We outline the process we used to construct the shared assessment, and provide some insight in how the student groups dealt with issues that arose.

Thinking Outside The"I Am The User" Box: A Trial Of Social-Emotional Design In Hci Education, Jo Jung, Barnard Clarkson, Martin Masek

Research outputs 2011

A socio-emotional approach to consider human-computer interaction (HCI) has emerged as a discipline responding to much neglected aspect of interaction design: the social nature and emotions of users. Teaching a socio-emotional design in practice can be challenging due to the newness and multidisciplinary nature. This paper reports a trial of a collaborative socio-emotional design project shared by two faculties and three design disciplines–interface design, software design, and 3D design. Success and challenges encountered during the project are presented to share our experience of teaching and managing a multidisciplinary collaboration project.

Shared Assessment: A Strategy For Managing Multidisciplinary Projects, Barnard Clarkson, Joo Jung, Martin Masek Jan 2011

Shared Assessment: A Strategy For Managing Multidisciplinary Projects, Barnard Clarkson, Joo Jung, Martin Masek

Research outputs 2011

Assessment-centered is the new black, apparently, if you believe recent research literature (eg. Boud & Associates, 2010) – but multi-disciplinary student assessments in multimedia are already challenging to assess. Naturally the more complex the project the more challenging it is for those administering the assessments, and in multi-unit settings (rather than end-of-course ‘capstone’ units) the complexity can be extreme. The consequential staff overload is insufficiently addressed even if the results are worth it. Shared assessments start with one large situated project and ask multiple staff running multiple units to collaborate whilst designing their assessments, all based around student teams ‘solving’ …

Resilience In Families With Same-Sex Parents [Journal Article], Natasha Griffiths, Julie Ann Pooley Jan 2011

Resilience In Families With Same-Sex Parents [Journal Article], Natasha Griffiths, Julie Ann Pooley

Research outputs 2011

Research suggests resilience can be viewed as a dynamic process facilitating positive functioning within the context of significant adversity. A nuclear family type that remains a controversial and stigmatized group is families with same-sex parents. Same sex families face a great number of challenges, due to the presence of heterosexism in society and they are often heavily criticised within the broad public domain. The current study adopted a phenomenological methodology to identify the family resilience processes utilised by same-sex families. Five lesbian couples raising children in Perth, Western Australia were interviewed. A thematic analysis technique was then conducted. Seven family …

Research outputs 2011

Contemporary impacts of anthropogenic climate change on ecosystems are increasingly being recognized. Documenting the extent of these impacts requires quantitative tools for analyses of ecological observations to distinguish climate impacts in noisy data and to understand interactions between climate variability and other drivers of change. To assist the development of reliable statistical approaches, we review the marine climate change literature and provide suggestions for quantitative approaches in climate change ecology. We compiled 267 peer-reviewed articles that examined relationships between climate change and marine ecological variables. Of the articles with time series data (n = 186), 75% used statistics to test …

Assessing The Influence Of Consanguinity On Congenital Heart Disease, Alan H. Bittles Jan 2011

Assessing The Influence Of Consanguinity On Congenital Heart Disease, Alan H. Bittles

Research outputs 2011

Numerous articles have been published linking consanguineous marriage to an elevated prevalence of congenital heart disease, with ventricular septal defects and atrial septal defects the most commonly cited disorders. While initially persuasive, on closer examination many of these studies have fundamental shortcomings in their design and in the recruitment of study subjects and controls. Improved matching of cases and controls, to include recognition of the long-established community boundaries within which most marriages are contracted, and the assessment of consanguinity within specific levels and types of marital union would improve and help to focus the study outcomes. At the same time, …

Metal-Semiconductor-Metal (Msm) Photodetectors With Plasmonic Nanogratings, Narottam K. Das, Ayman Karar, C L Tan, Mikhail Vasiliev, Kamal Alameh, Yong Tak Lee Jan 2011

Metal-Semiconductor-Metal (Msm) Photodetectors With Plasmonic Nanogratings, Narottam K. Das, Ayman Karar, C L Tan, Mikhail Vasiliev, Kamal Alameh, Yong Tak Lee

Research outputs 2011

We discuss the light absorption enhancement factor dependence on the design of nanogratings inscribed into metal-semiconductor-metal photodetector (MSM-PD) structures. These devices are optimized geometrically, leading to light absorption improvement through plasmon-assisted effects. Finite-difference time-domain (FDTD) simulation results show ~50 times light absorption enhancement for 850 nm light due to improved optical signal propagation through the nanogratings. Also, we show that the light absorption enhancement is strongly dependent on the nanograting shapes in MSM-PDs.

Research outputs 2011

Prostate cancer is the most common male cancer in developed countries and diagnosis and treatment carries with it substantial morbidity and related unmet supportive care needs. These difficulties may be amplified by physical inactivity and obesity. We propose to apply a multimodal intervention approach that targets both unmet supportive care needs and physical activity. A two arm randomised controlled trial will compare usual care to a multimodal supportive care intervention "Living with Prostate Cancer" that will combine self-management with tele-based group peer support. A series of previously validated and reliable self-report measures will be administered to men at four time …

High-Responsivity Plasmonics-Based Gaas Metal-Semiconductor-Metal Photodetectors, Ayman Karar, Narottam Das, Chee Leongtan, Kamal Alameh, Yong Tak Lee, Fouad Karouta

Research outputs 2011

We report the experimental characterization of high-responsivity plasmonics-based GaAs metal-semiconductor-metal photodetector (MSM-PD) employing metal nano-gratings. Both the geometry and light absorption near the designed wavelength are theoretically and experimentally investigated. The measured photocurrent enhancement is 4-times in comparison with a conventional single-slit MSM-PD. We observe reduction in the responsivity as the bias voltage increases and the input light polarization varies. Our experimental results demonstrate the feasibility of developing a high-responsivity, low bias-voltage high-speed MSM-PD.

Research outputs 2011

Bi-substituted iron garnet (Bi:IG) compounds synthesized in thin film form are the best semi-transparent magneto-optical (MO) materials for applications in magnetic recording, optical sensors, and photonics. These materials can possess attractive magnetic properties and the highest specific Faraday rotation in the visible and near-infrared spectral regions, if the deposited layers contain a high volumetric fraction of the garnet phase and possess high-quality surfaces and microstructure. In this paper, we study the effects of various deposition and annealing process parameters on the properties of Bi:IG and garnet-oxide nanocomposite films of several composition types fabricated using radio-frequency (RF) sputtering deposition followed by …

The Good Practice Principles: Silver Bullet Or Starter Gun?, Siri Barrett-Lennard, Katie Dunworth, Anne J. Harris Jan 2011

The Good Practice Principles: Silver Bullet Or Starter Gun?, Siri Barrett-Lennard, Katie Dunworth, Anne J. Harris

Research outputs 2011

The Good Practice Principles have provided the higher education sector with a framework for action in the area of academic language and learning (ALL); and the imprimatur of DEEWR has ensured that they have been nationally disseminated and are now widely recognised. Yet, while they have been nationally acknowledged as appropriate and desirable, the means by which they might be achieved is by no means certain. In order to realise these principles, ALL educators and colleagues in Australian institutions must grapple with major issues that arise chronologically over students’ academic careers. These issues include: how can we know whether students …

A Preliminary Introduction To The Otam: Exploring Users’ Perceptions Of Their On-Going Interaction With Adopted Technologies, Shirlee-Ann Knight, Janice M. Burn Jan 2011

A Preliminary Introduction To The Otam: Exploring Users’ Perceptions Of Their On-Going Interaction With Adopted Technologies, Shirlee-Ann Knight, Janice M. Burn

Research outputs 2011

A common criticism directed at Davis’ (1986; 1989) Technology Acceptance Model relates to its failure to adequately frame the “experienced” user’s ongoing adoption and exploitation of information technologies. Given the pervasive nature of technology into individual users’ ongoing, everyday communication and information interactions, along with the “new adopter” becoming an increasingly rare entity, the TAM is in danger of becoming a somewhat obsolete framework for investigating user-technology interaction. Presented is a critical analysis of the development and current state of the TAM, followed by a proposed addition to the existing Perceived Usefulness (PU) and Perceived Ease of Use (PEoU) TAM …

Physical Properties And Behaviour Of Highly Bi-Substituted Magneto-Optic Garnets For Applications In Integrated Optics And Photonics, Mohammad Nur E Alam, Mikhail Vasiliev, Kamal Alameh, Viacheslav Kotov

Research outputs 2011

Rare-earth and Bi-substituted iron garnet thin film materials exhibit strong potential for application in various fields of science and frontier optical technologies. Bi-substituted iron garnets possess extraordinary optical and MO properties and are still considered as the best MO functional materials for various emerging integrated optics and photonics applications. However, these MO garnet materials are rarely seen in practical photonics use due to their high optical losses in the visible spectral region. In this paper, we report on the physical properties and magneto-optic behaviour of high-performance RF sputtered highly bismuth-substituted iron garnet and garnet-oxide nanocomposite films of generic composition type …

Impact Of Nanograting Phase-Shift On Light Absorption Enhancement In Plasmonics-Based Metal-Semiconductor-Metal Photodetectors, Narottam K. Das, Ayman Karar, Chee Leong Tan, Kamal Alameh, Tak Lee

Research outputs 2011

The finite difference time-domain (FDTD) method is used to simulate the light absorption enhancement in a plasmonic metal-semiconductor-metal photodetector (MSM-PD) structure employing a metal nanograting with phase shifts. The metal fingers of the MSM-PDs are etched at appropriate depths to maximize light absorption through plasmonic effects into a subwavelength aperture. We also analyse the nano-grating phase shift and groove profiles obtained typically in our experiments using focused ion beam milling and atomic force microscopy and discuss the dependency of light absorption enhancement on the nano-gratings phase shift and groove profiles inscribed into MSM-PDs. Our simulation results show that the nano-grating …

Are Estimates Of The Value Of A Statistical Life Exaggerated?, Chris Doucouliagos, T D Stanley, Margaret J. Giles Jan 2011

Are Estimates Of The Value Of A Statistical Life Exaggerated?, Chris Doucouliagos, T D Stanley, Margaret J. Giles

Research outputs 2011

The magnitude of the value of astatisticallife (VSL) is critical to the evaluation of many health and safety initiatives. To date, the large and rigorous VSL research literature has not explicitly accommodated publication selectivity bias (i.e., the reduced probability that insignificant or negative VSL values are reported). This study demonstrates that doing so is essential. For studies that employ hedonic wage equations to estimate VSL, correction for selection bias reduces the average value of astatisticallife by 70–80%. Our meta-regression analysis also identifies several sources for the wide heterogeneity found among reported VSL estimates.

Theory Of The Scattering Of Light And Surface Plasmon Polaritons By Finite-Size Subwavelength Metallic Defects Via Field Decomposition, Guangyuan Li, Feng Xiao, Lin Cai, Kamal Alameh, Anshi Xu

Research outputs 2011

A theoretical model is presented for the scattering of light and surface plasmon polaritons (SPPs) by finite-size subwavelength metallic defects. Based on the decomposition of the scattered fields into SPPs and quasi-cylindrical waves (CWs), an SPP–CW model is developed to depict the multiple scattering of SPPs and CWs in finite-size defects using the elementary scattering processes in a single one. The involved elementary scattering of the CW, as well as the CW-related coefficients, which are difficult or even impossible to define and calculate according to classical scattering theory, is clarified. A close relationship between the scattering coefficients of the SPP …
