Tropicalization Of Seagrass Macrophytodetritus Accumulations And Associated Food Webs, Gilles Lepoint, Glenn A. Hyndes

Research outputs 2022 to 2026

Seagrass, systems export significant amounts of their primary production as large detritus (i.e. macrophytodetritus). Accumulations of exported macrophytodetritus (AEM) are found in many areas in coastal environment. Dead seagrass leaves are often a dominant component of these accumulations, offering shelter and/or food to numerous organisms. AEM are particular habitats, different from donor habitats (i.e. seagrass meadow, kelp or macroalgae habitats) and with their own characteristics and dynamics. They have received less attention than donor habitats despite the fact they often connect different coastal habitats, are the place of intense remineralization processes and shelter associated detritus food web. As for seagrass …

Do Personal Values Have An Effect On Self-Esteem In Middle Childhood?, Patricia R. Collins, Joanne Sneddon, Julie Ann Lee

Research outputs 2022 to 2026

Research on children's values (i.e., broad motivational goals) largely focuses on whether their values have a similar theoretical pattern of organization to those of adults, whether they hold similar value priorities to adults or adolescents, and how their values relate to social behavior. However, little is known about how values relate to wellbeing in middle childhood. We examined relations between the values of children aged 6–12 and aspects of their self-esteem, including global self-worth and five domain-specific-competencies. We found global self-worth and physical appearance were positively related to self-transcendence, conservation, and openness-to-change values, and negatively related to self-enhancement values. Social …

Activity Of Newest Generation Β-Lactam/Β-Lactamase Inhibitor Combination Therapies Against Multidrug Resistant Pseudomonas Aeruginosa, Robbie R. Haines, Papanin Putsathit, Katherine A. Hammer, Anna S. Tai

Research outputs 2022 to 2026

Multidrug resistant (MDR) P. aeruginosa accounts for 35 % of all P. aeruginosa isolated from respiratory samples of patients with cystic fibrosis (CF). The usefulness of β-lactam antibiotics for treating CF, such as carbapenems and later generation cephalosporins, is limited by the development of antibacterial resistance. A proven treatment approach is the combination of a β-lactam antibiotic with a β-lactamase inhibitor. New β-lactam/β-lactamase inhibitor combinations are available, but data are lacking regarding the susceptibility of MDR CF-associated P. aeruginosa (CFPA) to these new combination therapies. In this study we determined MIC values for three new combinations; imipenem-relebactam (I-R), ceftazidime-avibactam (CZA), …

The Intersection Of The Rule In Yerkey V Jones And Contemporary Anti-Discrimination Law In Australia – Can The ‘Special Wives’ Equity Survive?, Kenneth Yin, Mostafa M. Naser

Research outputs 2022 to 2026

The High Court in Yerkey v Jones considered the enforceability of a guarantee provided by a married woman to secure her husband’s debts. Dixon J said that although the relationship of husband and wife did not give rise to a presumption of undue influence, the law had never been divested completely of ‘the equitable presumption of an invalidating tendency’. Dixon J’s formulation was essentially adopted by the majority justices in Garcia v National Australia Bank and their judgment thus represents the definitive endorsement of Dixon J’s view. Kirby
J on the other hand rejected ‘the stereotype underlying Yerkey’, which he …

Myth-Busting In An Aboriginal Pre-University Bridging Program: Embedding Transformative Learning Pedagogy, Rebecca Bennett, Karin Strehlow, Braden Hill

Research outputs 2022 to 2026

Pre-university bridging programs can address the significant under-representation of Indigenous students in Australian universities by providing culturally supported alternative pathways into undergraduate study. However, successful completion of bridging programs does not always correlate with university enrolment for Indigenous students. This paper offers a pedagogical rationale for an Indigenous bridging program that aims to address this discrepancy. The program curriculum challenges deficit myths about Aboriginal and Torres Strait Islander Australians and education, while developing foundational academic skills for university study. Leveraging Transformative Learning and Cultural Interface theories, the program aims to empower students with the opportunity to develop their own narratives …

Deep Learning Inspired Feature Engineering For Classifying Tremor Severity, Ahmed Al Taee, Seyedehmarzieh Hosseini, Rami N. Khushaba, Tanveer Zia, Chin-Teng Lin, Adel Al-Jumaily

Research outputs 2022 to 2026

Bio-signals pattern recognition systems can be impacted by several factors with a potential to limit their associated performance and clinical translation. Among these factors, selecting the optimum feature extraction method, that can effectively exploit the interaction between the temporal and spatial information, is the most prominent. Despite the potential of deep learning (DL) models for extracting temporal, spatial, or temporal-spatial information, they are typically restricted by their need for a large amount of training data. The deep wavelet scattering transform (WST) is a relatively recent advancement within the DL literature to replace expensive convolution neural networks models with computationally less …

Patch Dynamics Driven By Wave Exposure In Subtidal Temperate Seaweeds Are Exacerbated By Warming Oceans, Yannick Mulders, Lydiane Mattio, Julia C. Phillips, Paul S. Lavery, Gary A. Kendrick, Thomas Wernberg

Research outputs 2022 to 2026

Over the past decades, ocean temperatures have been steadily increasing and are projected to continue to do so, stressing many temperate marine organisms. Changing temperatures do not affect ecosystems in isolation, but interact with many other factors in shaping ecological communities. We investigated the changes over 2 decades in subtidal temperate seaweed communities over a wave exposure gradient in Western Australia, a global warming hotspot. We found higher diversity in the seaweed community and a higher proportion of biomass of species with a warm affinity (expressed as the tropicalization index: TI) over time. There was no decline in biomass of …

Exploring Discordant Low Amyloid Beta And High Neocortical Tau Positron Emission Tomography Cases, Natasha Krishnadas, Vincent Doré, Simon M. Laws, Tenielle Porter, Fiona Lamb, Svetlana Bozinovski, Victor L. Villemagne, Christopher C. Rowe

Research outputs 2022 to 2026

Introduction: Neocortical 3R4R (3-repeat/4-repeat) tau aggregates are rarely observed in the absence of amyloid beta (Aβ). 18F-MK6240 binds specifically to the 3R4R form of tau that is characteristic of Alzheimer's disease (AD). We report four cases with negative Aβ, but positive tau positron emission tomography (PET) findings. Methods: All Australian Imaging, Biomarkers and Lifestyle study of aging (AIBL) study participants with Aβ (18F-NAV4694) and tau (18F-MK6240) PET scans were included. Centiloid < 25 defined negative Aβ PET (Aβ–). The presence of neocortical tau was defined quantitatively and visually. Results: Aβ– PET was observed in 276 participants. Four of these participants (one cognitively unimpaired [CU], two mild cognitive impairment [MCI], one AD) had tau tracer retention in a pattern consistent with Braak tau stages V to VI. Fluid biomarkers supported a diagnosis of AD. In silico analysis of APP, PSEN1, PSEN2, and MAPT genes did not identify relevant functional mutations. Discussion: Discordant cases were infrequent (1.4% of all Aβ– participants). In these cases, the Aβ PET ligand may not be detecting the Aβ that is present.
