When learning a language, motivation and emotions are central to the learning process and have considerable importance in learning. In Australia, despite the growing economic impact of its Asian neighbours and the great physical distance to France, French remains one of the most taught languages in various educational settings at different levels, and it appeals to many Australians. This review focuses on the motivations of West Australian adult learners of French. The aim of this paper is to explore students’ motivation and emotions towards their learning of French in Western Australia, teachers’ perceptions of these feelings, and how they are …

Including Pork In The Mediterranean Diet For An Australian Population: Protocol For Arandomised Controlled Trial Assessing Cardiovascular Risk And Cognitive Function, Alexandra T. Wade, Courtney R. Davis, Kathryn A. Dyer, Jonathan M. Hodgson, Richard Woodman, Hannah A. Keage, Karen J. Murphy

Research outputs 2014 to 2021

Background

The Mediterranean diet is characterised by the high consumption of extra virgin olive oil, fruits, vegetables, grains, legumes and nuts; moderate consumption of fish, poultry, eggs and dairy; and low consumption of red meat and sweets. Cross sectional, longitudinal and intervention studies indicate that a Mediterranean diet may be effective for the prevention of cardiovascular disease and dementia. However, previous research suggests that an Australian population may find red meat restrictions difficult, which could affect long term sustainability of the diet.

Methods

This paper outlines the protocol for a randomised controlled trial that will assess the cardiovascular and cognitive …

Universal Signal Conditioning Technique For Fiber Bragg Grating Sensors In Plc And Scada Applications, Gary Allwood, Graham Wild, Steven Hinkley

Research outputs 2014 to 2021

Optical fibre sensors, such as Fibre Bragg Gratings (FBGs), are growing in their utilisation, although very niche in their applications. To enable a more diverse range of end users, expensive application-specific optical fibre interrogation hardware needs to be made compatible with and, ideally, easily incorporated into existing instrumentation and measurement hardware. The Programmable Logic Controller (PLC) is an ideal example of hardware used for data acquisition in many industries. As such, a module that can be connected into an existing PLC slot to collect data from electrically-neutral, EMI-immune and versatile FBG sensors is of significant advantage to the growing optical …

Establishing The Theoretical Components Of Alexithymia Via Factor Analysis: Introduction And Validation Of The Attention-Appraisal Model Of Alexithymia, David Preece, Rodrigo Becerra, Alfred Allan, Ken Robinson, Justine Dandy

Research outputs 2014 to 2021

Alexithymia is an important mental health construct, but there is continuing debate regarding its definition and measurement. We attempt to resolve this definitional uncertainty in two ways. Firstly, we trace the development of the alexithymia construct, focusing particularly on what we call the Toronto and Amsterdam models, and examine a body of empirical research that shows strong support for the hypothesis that alexithymia consists of three components (difficulty identifying feelings, difficulty describing feelings, and externally orientated thinking). Based on these components, we formulate an alternate theoretical model of alexithymia, the attention-appraisal model of alexithymia, that aligns alexithymia theory with …

Prevalence Of Binary Toxin Positive Clostridium Difficile In Diarrhoeal Humans In The Absence Of Epidemic Ribotype 027, Alan M. Mcgovern, Grace O. Androga, Daniel R. Knight, Mark W. Watson, Briony Elliott, Niki F. Foster, Barbara J. Chang, Thomas V. Riley

Research outputs 2014 to 2021

Virulence of Clostridium difficile is primarily attributed to the large clostridial toxins A and B while the role of binary toxin (CDT) remains unclear. The prevalence of human strains of C. difficile possessing only CDT genes (A¯B¯CDT ⁺) is generally low (< 5 %), however, this genotype is commonly found in neonatal livestock both in Australia and elsewhere. Zoonotic transmission of C. difficile has been suggested previously. Most human diagnostic tests will not detect A¯B¯CDT ⁺ strains of C. difficile because they focus on detection of toxin A and/or B. We performed a prospective investigation into the prevalence and genetic characteristics of A¯B¯CDT ⁺ C. difficile in symptomatic humans. All glutamate dehydrogenase or …

To address this, web-based physical activity interventions, which have the potential to reach large numbers of users at low costs, have received considerable attention. To fully realise the potential of such interventions, there is a need to further increase their appeal to boost engagement and retention, and sustain intervention effects over longer periods of time. This randomised controlled trial aims to evaluate the efficacy of a gamified physical activity intervention that connects users to each …

Timing Anthropogenic Stressors To Mitigate Their Impact On Marine Ecosystem Resilience, Paul Pao-Yen Wu, Kerrie Mengersen, Kathryn Mcmahon, Gary A. Kendrick, Kathryn Chartrand, Paul H. York, Michael A. Rasheed, M. Julian Caley

Research outputs 2014 to 2021

Better mitigation of anthropogenic stressors on marine ecosystems is urgently needed to address increasing biodiversity losses worldwide. We explore opportunities for stressor mitigation using whole-of-systems modelling of ecological resilience, accounting for complex interactions between stressors, their timing and duration, background environmental conditions and biological processes. We then search for ecological windows, times when stressors minimally impact ecological resilience, defined here as risk, recovery and resistance. We show for 28 globally distributed seagrass meadows that stressor scheduling that exploits ecological windows for dredging campaigns can achieve up to a fourfold reduction in recovery time and 35% reduction in extinction risk. Although …

Players in each condition were categorised as ‘fast’ (FAST) or ‘slow’ (SLOW) using median trial times from baseline testing. Players recorded greater isometric strength improvements following EPE (ES = − 0.54 to 1.80). Whilst these …

Trophic Roles Of Tadpoles In Tropical Australian Streams, Katrin Schmidt, Melanie L. Blanchette, Richard G. Pearson, Ross A. Alford, Aaron M. Davis

Research outputs 2014 to 2021

Tadpoles can be abundant consumers in stream ecosystems, and may influence the structure and function of streams through their feeding activities and interactions with other organisms. To understand the contribution of tadpoles to stream functioning, and the potential impact of their loss, it is necessary to determine their diets and how they might influence food-web structure. Using gut-content analysis and stable-isotope analysis of N and C, we determined the main food sources and trophic positions of tadpoles of five native frog species, invertebrates, and fish in upland and lowland Australian Wet Tropics streams. Omnivory was prevalent among the tadpoles and …

Gradient Descent Localization In Wireless Sensor Networks, Nuha A.S. Alwan, Zahir M. Hussain

Research outputs 2014 to 2021

Meaningful information sharing between the sensors of a wireless sensor network (WSN) necessitates node localization, especially if the information to be shared is the location itself, such as in warehousing and information logistics. Trilateration and multilateration positioning methods can be employed in two-dimensional and threedimensional space respectively. These methods use distance measurements and analytically estimate the target location; they suffer from decreased accuracy and computational complexity especially in the three-dimensional case. Iterative optimization methods, such as gradient descent (GD), offer an attractive alternative and enable moving target tracking as well. This chapter focuses on positioning in three dimensions using time-of-arrival …

Stimulation Of Anterior Thalamic Nucleus Protects Hippocampus Neural Injury In Kainic Acid-Induced Epileptic Rats, Na Yan, Ning Chen, Wei Gao, Wei Wang

Research outputs 2014 to 2021

Anterior nucleus of thalamus (ANT) stimulation has been proved to be effective in the treatment of refractory epilepsy, but the underlying mechanisms remain to be elucidated. We examined the role of ANT stimulation on hippocampal neuron death after seizures induced by kainic acid (KA). Our data showed that ANT stimulation could significantly rescue neurons from death induced by seizures, by reducing the release of cytochrome c (cyto c) and also via apoptosis-inducing factor (AIF) induced by seizures through inhibiting the activated caspase-9 and caspase-3. Our data suggest that ANT stimulation may protect against neuronal loss and reduce neuronal injury in …

Affordance Boundaries Are Defined By Dynamic Capabilities Of Parkour Athletes In Dropping From Various Heights, James L. Croft, John E.A. Bertram

Research outputs 2014 to 2021

Available behaviors are determined by the fit between features of the individual and reciprocal features of the environment. Beyond some critical boundary certain behaviors become impossible causing sudden transitions from one movement pattern to another. Parkour athletes have developed multiple movement patterns to deal with their momentum during landing. We were interested in whether drop distance would cause a sudden transition between a two-footed (precision) landing and a load-distributing roll and whether the transition height could be predicted by dynamic and geometric characteristics of individual subjects. Kinematics and ground reaction forces were measured as Parkour athletes stepped off a box …
