Supporting The Performance Of Noongar Language In Hecate, Clint Bracknell, Kylie Bracknell, Susan F. Studham, Luzita Fereday

Research outputs 2014 to 2021

As the first adaptation of a complete Shakespearean work presented entirely in one Aboriginal language of Australia, Hecate is a landmark production in Australian theatre. The Noongar language of the southwest of Western Australia is a critically endangered language impacted by colonisation since the early 1800s and suppressed until the 1970s. Working with an all-Noongar cast learning what is by birthright their mother-tongue, the Noongar language, on a full Shakespearean work presents a range of challenges. Consideration of effective rehearsal strategies to support brave spaces for the cast to flourish holistically, both as language learners and performers, was imperative. As …


Development And Validation Of The Holistic Cognition Scale, Andrei A. Lux, Steven L. Grover, Stephen T. Teo Jan 2021

Development And Validation Of The Holistic Cognition Scale, Andrei A. Lux, Steven L. Grover, Stephen T. Teo

Research outputs 2014 to 2021

This paper introduces a new scale to measure cognitive cultural differences, drawing on the theory of analytic versus holistic thought. Examining culture from a cognitive perspective is a challenge to traditional values-based approaches. Existing measures based on this framework are methodologically problematic and warrant renewal. This paper presents development and validation studies for a new instrument that measures analytic versus holistic cognitive tendencies at the individual level. The scale assesses four previously established dimensions: attention, causality, contradiction, and change. The present work follows well-established scale development protocols and the results show that the 16-item Holistic Cognition Scale (HCS) is a …

Evidence Of Large Increases In Sedimentation Rates Due To Fish Trawling In Submarine Canyons Of The Gulf Of Palermo (Sw Mediterranean), Sarah Paradis, Claudio Lo Iacono, Pere Masqué, Pere Puig, Albert Palanques, Tommaso Russo, The Island Cruise Tem

Research outputs 2014 to 2021

Bottom trawling in submarine canyons can affect their natural sedimentation rates, but studies addressing this issue are still scarce. In the Gulf of Palermo (SW Mediterranean), bottom trawling occurs on the slope around Oreto, Arenella and Eleuterio canyons. Analyses of excess 210Pb concentrations and grain size fractions in sediment cores from their canyon axes revealed that sedimentation rates and silt contents increased in all canyons in the 1980s, due to the expansion of more powerful trawlers ( > 500 HP) to deeper fishing grounds. In Eleuterio and Arenella canyons, sedimentation rates increased by an order of magnitude (0.1-1.4 cm·yr-1), whereas they …

Research outputs 2014 to 2021

Wettability is one of the main parameters controlling CO2 injectivity and the movement of CO2 plume during geological CO2 sequestration. Despite significant research efforts, there is still a high uncertainty associated with the wettability of CO2/brine/rock systems and how they evolve with CO2 exposure. This study, therefore, aims to measure the contact angle of sandstone samples with varying clay content before and after laboratory core flooding at different reservoir pressures, of 10 MPa and 15 MPa, and a temperature of 323 K. The samples’ microstructural changes are also assessed to investigate any potential alteration …

Coronavirus disease 2019 (COVID-19) remains a major health challenge globally. Previous studies have suggested that changes in the glycosylation of IgG are closely associated with the severity of COVID-19. This study aimed to compare the profiles of IgG N-glycome between COVID-19 patients and healthy controls. A case-control study was conducted, in which 104 COVID-19 patients and 104 age- and sex-matched healthy individuals were recruited. Serum IgG N-glycome composition was analyzed by hydrophilic interaction liquid chromatography with the ultra-high-performance liquid chromatography (HILIC-UPLC) approach. COVID-19 patients have a decreased level of IgG fucosylation, which upregulates antibody-dependent cell cytotoxicity (ADCC) in …

Research outputs 2014 to 2021

Background

Delirium is more prevalent in older people and estimated to occur in up to 50% of the hospital population. Delirium comprises a spectrum of behaviours, including cognitive and attention deficits, and fluctuating levels of consciousness, often associated with an underlying physiological disturbance. Delirium has been increasingly associated with adverse outcomes. Although often preventable or can at least be mitigated, delirium may not be a standard part of assessment and thus may not be recognized in the early stages when it is most likely to be treated successfully. The aim of this study was to evaluate the level of knowledge …

‘Believe In Me, And I Will Too’: A Study Of How Teachers’ Expectations Instilled Confidence In Grade 10 Students, Olivia Johnston, Helen Wildy, Jennifer Shand

Research outputs 2014 to 2021

Teacher expectation research has continued to establish an association between what teachers expect of their students and what students accomplish academically. These expectations affect students when they are communicated by teachers through differential treatment in the class, but no qualitative research has sought adolescent students’ points of view about how they experience teacher expectation effects. This paper presents new research findings that explain how Grade 10 students experienced their teachers’ expectations in ways that they reflected impacted their academic outcomes. Classic grounded theory methods were used to develop this new knowledge, which has implications for how teachers are educated for, …


Short Word-Length Entering Compressive Sensing Domain: Improved Energy Efficiency In Wireless Sensor Networks, Nuha A. S. Alwan, Zahir M. Hussain Jan 2021

Short Word-Length Entering Compressive Sensing Domain: Improved Energy Efficiency In Wireless Sensor Networks, Nuha A. S. Alwan, Zahir M. Hussain

Research outputs 2014 to 2021

This work combines compressive sensing and short word-length techniques to achieve localization and target tracking in wireless sensor networks with energy-efficient communication between the network anchors and the fusion center. Gradient descent localization is performed using time-of-arrival (TOA) data which are indicative of the distance between anchors and the target thereby achieving range-based localization. The short word-length techniques considered are delta modulation and sigma-delta modulation. The energy efficiency is due to the reduction of the data volume transmitted from anchors to the fusion center by employing any of the two delta modulation variants with compressive sensing techniques. Delta modulation allows …


Improving Basalt Wettability To De-Risk Co2 Geo-Storage In Basaltic Formations, Stefan Iglauer, Ahmed Al-Yaseri Jan 2021

Improving Basalt Wettability To De-Risk Co2 Geo-Storage In Basaltic Formations, Stefan Iglauer, Ahmed Al-Yaseri

Research outputs 2014 to 2021

CO2 geo-storage in basaltic formations has recently been identified as a viable option to rapidly dispose large quantities of CO2, hence mitigating anthropogenic CO2 emissions. However, it has been shown that basalt is weakly water-wet or intermediate-wet at typical storage conditions, which reduces capillary trapping capacities and increases lateral and vertical spreading of the CO2 plume; and these effects increase project risk. We thus propose here to prime basalt surfaces with anionic surfactant (here we used sodium dodecyl benzene sulfonate), and demonstrate that such priming is highly efficient, and renders the basalt completely water-wet even …

Assessing The Applicability Of Three Approaches To Design-Oriented Research, Jing Zhou, Christopher Kueh, Yi Lin

Research outputs 2014 to 2021

The three main approaches in inquisitive research design are qualitative, quantitative, and mixed methods [1]. However, recent developments in the research field have resulted in multiple other approaches, borrowing ideas from a broad range of fields. One such approach is the practice-led approach. This approach involves an efficient design process, novel qualitative interviewing methods, together with data mining procedures from quantitative data collection [2]. This paper assesses the practice-led approach used in user experience (UX) design, together with three approaches: co-design, service design, and reflective practice.

A Range Error Reduction Technique For Positioning Applications In Sports, Adnan Waqar, Iftekhar Ahmad, Daryoush Habibi, Quoc V. Phung

Research outputs 2014 to 2021

In recent times, ultra-wideband (UWB)-based positioning systems have become popular in sport performance monitoring. UWB positioning system uses time of arrival to calculate the range data between devices (i.e. anchors, tags), and then use trilateration algorithms to estimate position coordinates. In practical applications, non-line-of-sight transmissions and multipath propagations lead to inaccurate range data and lower positioning accuracy. This paper introduces a range error minimisation algorithm to address this limitation of error in range data in UWB-based positioning system. The proposed solution analyses the range error for each anchor and sequentially reduces this error based on the distance between each anchor …

We also present the knowledge gaps in PCa genetics in Africa and why Africa represents an untapped potential ground for genetic studies on PCa. A significant number of …


Infrequent Pattern Detection For Reliable Network Traffic Analysis Using Robust Evolutionary Computation, A. N. M. Bazlur Rashid, Mohiuddin Ahmed, Al-Sakib K. Pathan Jan 2021

Infrequent Pattern Detection For Reliable Network Traffic Analysis Using Robust Evolutionary Computation, A. N. M. Bazlur Rashid, Mohiuddin Ahmed, Al-Sakib K. Pathan

Research outputs 2014 to 2021

While anomaly detection is very important in many domains, such as in cybersecurity, there are many rare anomalies or infrequent patterns in cybersecurity datasets. Detection of infrequent patterns is computationally expensive. Cybersecurity datasets consist of many features, mostly irrelevant, resulting in lower classification performance by machine learning algorithms. Hence, a feature selection (FS) approach, i.e., selecting relevant features only, is an essential preprocessing step in cybersecurity data analysis. Despite many FS approaches proposed in the literature, cooperative co-evolution (CC)-based FS approaches can be more suitable for cybersecurity data preprocessing considering the Big Data scenario. Accordingly, in this paper, we have …

Collaboration And Opportunism In Megaproject Alliance Contracts: The Interplay Between Governance, Trust And Culture, Peter Galvin, Stephane Tywoniak, Janet Sutherland

Research outputs 2014 to 2021

Alliance contracts have been introduced in megaprojects to improve the alignment of objectives, risk and reward between client and contractor. However, the relational norms of alliances are not sufficient on their own to eliminate opportunistic behaviors. This study shows that, investing in mechanisms supportive of governance, culture, and trust provides a platform upon which firms may foster collaboration and limit self-interest oriented behavior amongst alliance partners. Our qualitative case study of a major project-based organization reveals the impact of these mechanisms, and more pointedly, how they interact and often reinforce each other. Governance, culture and trust are interlinked and complementary, …


Educative Power And The Respectful Curricular Inclusion Of Aboriginal And Torres Strait Islander Music, Michael Webb, Clint Bracknell Jan 2021

Educative Power And The Respectful Curricular Inclusion Of Aboriginal And Torres Strait Islander Music, Michael Webb, Clint Bracknell

Research outputs 2014 to 2021

This chapter argues for the full, respectful curricular inclusion of Aboriginal and Torres Strait Islander music in order to promote a more balanced and equitable social and cultural vision of the nation-state in Australian schools. It challenges views that claim Indigenous cultures have been irretrievably lost or are doomed to extinction, as well as the fixation on musical authenticity. We propose that the gradual broadening of Indigenous musical expressions over time and the musical renaissance of the new millennium have created an unprecedented opportunity for current music educators to experience the educative power of Aboriginal and Torres Strait Islander music. …

Heterogeneous Tidal Marsh Soil Organic Carbon Accumulation Among And Within Temperate Estuaries In Australia, Connor Gorham, Paul S. Lavery, Jeffrey J. Kelleway, Pere Masque, Oscar Serrano

Research outputs 2014 to 2021

The scarcity of data on tidal marsh soil accumulation rates (SAR) and soil organic carbon accumulation rates (CAR) globally precludes a comprehensive assessment of the role of tidal marshes in climate change mitigation and adaptation. Particularly few data exist from the southern hemisphere and for Australia in particular, which contains ~24% of globally recognised tidal marsh extent. Here we estimate SAR and CAR over the last 70 years using 210Pb-based geochronologies in temperate estuarine tidal marsh ecosystems in southern Western Australia (WA). Specifically, we assessed tidal marsh ecosystems situated in two geomorphic settings (marine vs. fluvial deltas) within 10 wave-dominated, …
