Preparing For End Of Life In A New Country: A Grounded Theory Study On African Migrants Living In Australia, Gertrude Gondwe Phiri

Theses: Doctorates and Masters

African migration to Australia has grown in the past 20 to 25 years with many migrants staying permanently. This has led to migrants dying away from their birthplaces where family is responsible for end-of-life care planning for the individual. Although migrating to Australia is considered a great achievement, many migrants also experienced challenges. Previous studies have explored the barriers faced by migrants in relation to end-of-life care but have not addressed the cause of those challenges. This constructivist grounded theory study examines how migrants from three African countries, Malawi, Zambia, and Zimbabwe (MZZ) prepare for end-of-life in Australia. The study …

Melatonin Application Suppresses Oxidative Stress And Maintains Fruit Quality Of Cold Stored ‘Esperanza’ Raspberries By Regulating Antioxidant System, Hafiz M. S. Shah, Zora Singh, Mahmood Ul Hasan, Jashanpreet Kaur, Eben Afrifa-Yamoah, Andrew Woodward

Research outputs 2022 to 2026

Raspberries are highly perishable and have a short storage life. To extend its storage life, we evaluated the impact of preharvest melatonin (MEL) application (0, 50, 100, 200 mol L−1), three days before harvest, on the activities of oxidative and antioxidative enzymes and quality attributes in ‘Esperanza’ raspberries up to 10 d cold storage. The 200 mol L−1 MEL-treated raspberries exhibited a significant reduction in disease incidence while maintaining higher marketable fruit and activities of superoxide dismutase, glutathione reductase, dehydroascorbate reductase, monodehydroascorbate reductase, ascorbate peroxidase and catalase as compared to control. Additionally, it reduced activities of polyphenol oxidase, peroxidase and …

Research outputs 2022 to 2026

The potential threat of fisheries on seabed carbon is a topic of growing concern, yet existing literature presents inconsistencies leaving experts divided on the topic. We conducted a global meta-analysis to synthesize the current knowledge and quantify how demersal fishing impacts various biogeochemical properties. Direct impact studies revealed overall reductions in chlorophyll-a (Chl-a, 17%), phaeopigments (24%), and proteins (32%). Effects on these reactive compounds were more pronounced on surface sediment (0–2 cm), where the impact on total organic carbon (TOC) also became significant, demonstrating the effect of gear penetration, and highlighting that sampling strategies combining sediment layers can mask observed …

Pryce, Rebecca Wake, Aus A.L. Molan, T. F. Paton, Tim J.J. Inglis

Research outputs 2022 to 2026

Background. The COVID-19 pandemic demonstrated a need for robust SARS-CoV-2 test evaluation infrastructure to underpin biosecurity and protect the population during a pandemic health emergency. Gap statement. The first generation of rapid antigen tests was less accurate than molecular methods due to their inherent sensitivity and specificity shortfalls, compounded by the consequences of self-testing. This created a need for more accurate point-of-care SARS-CoV-2 detection methods. Aim. Here we present the lessons-learned during the COVID-19 emergency response in Western Australia including the detailed set-up, evaluation and operation of rapid antigen test in a state-run drive-through sample collection service during the COVID-19 …

Research outputs 2022 to 2026

Climate change is of great concern to all age groups but in particular to children. “Simple” climate models have been in place for a long time and can be used effectively with post-16 students. For younger children, modifications are required, and we describe in this paper the development and use of two such models. The first (the Granny Model) is a pictorial version of the model that has been used extensively with primary and early secondary school aged children (14 and younger). The second is an online version of the simple climate model that can be used without recourse to …

Diel Movement Patterns In Nominally Nocturnal Coral Reef Fishes (Haemulidae And Lutjanidae): Intra Vs. Interspecific Variation, William P. Collins, David R. Bellwood, Renato A. Morais, Nathan J. Waltham, Alexandre C. Siqueira

Research outputs 2022 to 2026

Movement of animals, habitat connectivity, and nutrient transport are key elements in the ecological functioning of coral reef ecosystems. However, most studies have focused on the diurnal component of these aspects; nocturnal patterns are less known. Our study aims to address this knowledge gap by assessing diel movement patterns in ecologically and commercially important nocturnal coral reef fishes. We evaluate 122-days of acoustic telemetry data from 4 nocturnal species in 2 coral reef fish families (Haemulidae and Lutjanidae) on the Great Barrier Reef. For all species, we found a clear division between daytime resting areas on the reef and a …

Research outputs 2022 to 2026

INTRODUCTION: We investigated longitudinal associations between self-reported exercise and Alzheimer's disease (AD)-related biomarkers in individuals with autosomal dominant AD (ADAD) mutations. METHODS: Participants were 308 ADAD mutation carriers aged 39.7 ± 10.8 years from the Dominantly Inherited Alzheimer's Network. Weekly exercise volume was measured via questionnaire and associations with brain volume (magnetic resonance imaging), cerebrospinal fluid biomarkers, and brain amyloid beta (Aβ) measured by positron emission tomography were investigated. RESULTS: Greater volume of weekly exercise at baseline was associated with slower accumulation of brain Aβ at preclinical disease stages β = –0.16 [–0.23 to –0.08], and a slower decline in …

Towards An Indigenous-Informed Multispecies Collaboratory, Sandra Wooltorton, Peta J. White

Research outputs 2022 to 2026

How does Australia's latest Indigenous defeat relate to Environmental Education? The answer is direct complicity. This paper begins with the premise that the failure of Australia's 2023 referendum on "The Voice to Parliament"is directly connected with education. The chapter builds on the proposition that local and Indigenous public knowledge could - and should - be the heart of environmental education. We apply a post-qualitative practice that is underpinned by innovative feminisms and the post-qualitative methods within a Multispecies Collaboratory, an experimental way of transforming our learning by attending to the responsive, relational world of all beings. We use this practice …

Rapid Analysis Of N-Nitrosamines In Urine Using Ultra High-Pressure Liquid Chromatography-Mass Spectrometry, S. Shinde, K. D. Croft, J. M. Hodgson, C. P. Bondonno

Research outputs 2022 to 2026

N-Nitrosamines, carcinogenic compounds present in dietary and environmental sources and formed endogenously, are believed to be linked with the presence of nitrate and nitrite, both within dietary sources and after intake. To fully evaluate this potential threat to human health, an accurate analytical method to measure N-nitrosamines in biological matrices is necessary. We report a simple, fast, selective mass spectrometry method to detect N-nitrosamines in human urine. Analysis of seven N-nitrosamines, N-nitrosodimethylamine (NDMA), N-nitrosomethylethylamine (NMEA), N-nitrosodiethylamine (NDEA), N-nitrosopiperdine (NPIP), N-nitrosopyrrolidine (NPYR), N-nitrosodi-N-propylamine (NDPA) and N-nitrosodi-N-butylamine (NDBA) in urine was quantitated using Ultra High-Pressure Liquid Chromatography-tandem Mass spectrometry (UHPLC-MS/MS).

Research outputs 2022 to 2026

One of the world’s largest “blue carbon” ecosystems, Louisiana’s tidal wetlands on the US Gulf of Mexico coast, is rapidly being lost. Louisiana’s strong legal, regulatory, and monitoring framework, developed for one of the world’s largest tidal wetland systems, provides an opportunity for a programmatic approach to blue carbon accreditation to support restoration of these ecologically and economically important tidal wetlands. Louisiana’s coastal wetlands span ∼1.4 million ha and accumulate 5.5–7.3 Tg yr−1 of blue carbon (organic carbon), ∼6%–8% of tidal marsh blue carbon accumulation globally. Louisiana has a favorable governance framework to advance blue carbon accreditation, due to centralized …

The Federal Future Of Medication Abortion, Michelle S. Simon

Elisabeth Haub School of Law Faculty Publications

A majority of Americans believe that there should be a right to abortion, at least in some cases. Yet a vocal and determined minority has its sights set on a complete ban on all abortions everywhere in the United States. In many states, these anti-abortion activists have achieved their goal through new laws and limitations enacted in the wake of the Supreme Court's 2022 decision in Dobbs. Anti-abortion advocates are also challenging the Food and Drug Administration's regulatory approval of mifepristone, one of the drugs used in medication abortion (also known as medical abortion). The FDA had initially approved mifepristone …

Gender Regrets: Banning Abortion And Gender-Affirming Care, Margot J. Pollans, Noa Ben-Asher

Elisabeth Haub School of Law Faculty Publications

This Article analyzes the use of “regret” in the campaigns to ban GAC and abortion. It identifies two overlapping threads. First, both campaigns against medical care point to protection of patients from future regret as a legitimate state interest justifying restrictions on providing medical care. Second, both rely on concerns about regret to redefine the legal meaning of “informed consent” and make it easier for potential future plaintiffs to prevail in civil suits against providers of medical care. In doing so, both treat the emotion of regret as a distinct injury that may give rise to a range of legal …

Submarine Groundwater Discharge At A Mega-Tidal Beach, Raymond D. Craddock, Aaron A. Mohammed, Joseph J. Tamborski, Barret L. Kurylyk

OES Faculty Publications

Tidally influenced groundwater systems in coastal environments represent important mixing zones of fresh groundwater and circulating seawater, manifesting as submarine groundwater discharge (SGD). Water circulation induced by tidal pumping enhances the exchange of chemicals between aquifers and coastal waters and thereby influences the biogeochemistry of coastal zones. Here, we report the results of an SGD field study conducted at a steep, mega-tidal sand and gravel beach along the Canadian coast of the Bay of Fundy, a region with the world's highest tides (semi-diurnal tidal ranges exceeding 10 m). Several physical and geochemical measurement techniques were employed to document the spatiotemporal …

A Comparison Of Adenosine Triphosphate With Other Metrics Of Microbial Biomass In A Gradient From The North Atlantic To The Chesapeake Bay, Alexander B. Bochdansky, Amber A. Beecher, Joshua R. Calderon, Alison N. Stouffer, Nyjaee N. Washington

OES Faculty Publications

A new, simplified protocol for determining particulate adenosine triphosphate (ATP) levels allows for the assessment of microbial biomass distribution in aquatic systems at a high temporal and spatial resolution. A comparison of ATP data with related variables, such as particulate carbon, nitrogen, chlorophyll, and turbidity in pelagic samples, yielded significant and strong correlations in a gradient from the tributaries of the Chesapeake Bay (sigma-t = 8) to the open North Atlantic (sigma-t = 29). Correlations varied between ATP and biomass depending on the microscopic method employed. Despite the much greater effort involved, biomass determined by microscopy correlated poorly with other …

Re-Evaluating Hydrogen Sulfide As A Sink For Cadmium And Zinc In The Oxic To Suboxic Upper Water Column Of The Pacific Ocean, N. R. Buckley, E. E. Black, J. A. Kenyon, N. T. Lanning, M. Sieber, T. M. Conway, J. N. Fitzsimmons, G. A. Cutter

OES Faculty Publications

Hydrogen sulfide is produced by heterotrophic bacteria in anoxic waters and via carbonyl sulfide hydrolysis and phytoplankton emissions under oxic conditions. Apparent losses of dissolved cadmium (dCd) and zinc (dZn) in oxygen minimum zones (OMZs) of the Atlantic and Pacific Oceans have been attributed to metal-sulfide precipitation formed via dissimilatory sulfate reduction. It has also been argued that such a removal process could be a globally important sink for dCd and dZn. However, our studies from the North Pacific OMZ show that dissolved and particulate sulfide concentrations are insufficient to support the removal of dCd via precipitation. In contrast, apparent …

A Proxy System Modeling Approach To Combining Tree-Ring And Sediment-Based Paleotempestological Records, Elizabeth J. Wallace, Sylvia Dee, Joshua Bregy, Kerry A. Emanuel

OES Faculty Publications

The short and biased observational record of tropical cyclones (TCs) limits scientific understanding of how these destructive storms respond to climate forcing. Paleohurricane records use natural archives (tree rings, coarse-grained sediment) to reconstruct TC properties (frequency and intensity of rainfall, wind) over the past few hundreds to thousands of years. However, different sensitivities and sampling biases in the various paleohurricane proxies restrict our ability to compile these records into regional or basin-scale TC estimates. Here we test how well pseudo tree-ring records of paleohurricanes capture TC rainfall and occurrence. Using a large set of statistically downscaled storms forced with the …

Contrasting Nitrogen Dynamics Across The Mid-Atlantic Bight Shelfbreak Front: Insights From Nitrate Dual Isotopes And Nitrifier Gene Abundance, Yifan Zhu, Margaret R. Mulholland, Corday R.

Observations and model studies suggest that front dynamics can enhance phytoplankton productivity. This study tested whether frontal systems also increase the abundance of nitrifying microbes and nitrogen recycling during repeat sampling transects across the Mid‐Atlantic Bight shelfbreak in July 2019. We measured ammonium concentrations, nitrate dual isotopes (δ¹⁵N, δ¹⁸O), and ammonia monooxygenase subunit A (amoA) genes of ammonia‐oxidizing archaea (AOA) and bacteria (AOB). In subsurface shelf waters, ammonium concentrations exceeded 2 μmol L⁻¹, due to a temporary imbalance in regeneration from sinking particles and subsequent nitrification. The inverse correlation between nitrate δ^{15 …}

Widespread Crab Burrows Enhance Greenhouse Gas Emissions From Coastal Blue Carbon Ecosystems, Kai Xiao, Yuchen Wu, Feng Pan, Yingrong Huang, Hebo Peng, Meiqing Lu, Yan Zhang, Hailong Li, Yan Zheng, Chunmiao Zheng, Yan Liu, Nengwan Chen, Leilei Xiao, Guangxuan Han, Yasong Li, Pei Xin, Ruili Li, Bochao Xu, Faming Wang, Joseph J.

OES Faculty Publications

Fiddler crabs, as coastal ecosystem engineers, play a crucial role in enhancing biodiversity and accelerating the flow of material and energy. Here we show how widespread crab burrows modify the carbon sequestration capacity of different habitats across a large climatic gradient. The process of crab burrowing results in the reallocation of sediment organic carbon and humus. Crab burrows can increase more greenhouse gases emissions compared to the sediment matrix (CO2: by 17-30%; CH4: by 49-141%). Straightforward calculations indicate that these increased emissions could offset 35-134% of sediment carbon burial in these two ecosystems. This research highlights the complex interactions between …

Long-Term Accretion Rates In Uk Salt Marshes Derived From Elevation Difference Between Natural And Reclaimed Marshes, Gerd Masselink, Robert B. Jones

School of Biological and Marine Sciences

The future of salt marshes depends in a large part on the balance between the future rate of marsh accretion and the future rate of sea-level rise (SLR). Current accretion rates can provide some insight into future resilience of salt marshes to SLR, but representative long-term rates across the complete salt marsh area are difficult to obtain. Here, we introduce a new method based on the elevation difference between a natural marsh and a neighbouring reclaimed marsh. The method, referred to as the ‘reclaimed salt marsh method’, was applied to 19 UK salt marshes and yielded a UK-averaged accretion rate …

Do I Sound Anxious? Emotional Arousal Is Linked To Changes In Vocalisations In Domestic Chicks (Gallus Gallus Dom.), Sarah A. Collins, Katherine Herborn, Kenneth J. Sufka, Lucy Asher, Ben Brilot

School of Biological and Marine Sciences

A major goal in animal welfare science is the development of methods that quantify or ‘read-out’ current affective states in freely behaving animals. In mammalian models, changes in acoustic parameters within vocalisations have been linked to differences in emotional arousal, although there are very few studies showing changes in vocalisations that act as indicators of valence (positive or negative affect). Currently, there are very few studies on vocal indicators of emotion in birds. To determine the link between acoustic parameters within vocalisations and emotion in domestic chicks (Gallus gallus dom.), we used a well-validated paradigm that purports to elicit two …

Victim Of Changes? Marine Macroalgae In A Changing World, Mick E. Hanley, Louise B. Firth, Andy Foggo

School of Biological and Marine Sciences

Background Marine macroalgae (‘seaweeds’) are a diverse and globally distributed group of photosynthetic organisms that together generate considerable primary productivity, provide an array of different habitats for other organisms, and contribute many important ecosystem functions and services. As a result of continued anthropogenic stress on marine systems, many macroalgal species and habitats face an uncertain future, risking their vital contribution to global productivity and ecosystem service provision. Scope After briefly considering the remarkable taxonomy and ecological distribution of marine macroalgae, we review how the threats posed by a combination of anthropogenically induced stressors affect seaweed species and communities. From there …

Invasive Macroalgae In Native Seagrass Beds: Vectors Of Spread And Impacts, Louise Firth, Andy Foggo, Thomas Watts, Antony Knights, Stacey Deamicis

School of Biological and Marine Sciences

Background and AimsWorldwide, invasive species are spreading through marine systems at an unprecedented rate with both positive and negative consequences for ecosystems and the biological functioning of organisms. Human activities from shipping to habitat damage and modification are known vectors of spread, although biological interactions including epibiosis are increasingly recognized as potentially important to introduction into susceptible habitats.MethodsWe assessed a novel mechanism of spread – limpets as transporters of an invasive alga, Sargassum muticum, into beds of the seagrass Zostera marina – and the physiological impact of its invasion. The association of S. muticum with three limpet species and other …

Qualitative Interviews, Abraham Kenin

Research Datasets

Background: Within the context of a growing sub-Saharan Africa (SSA) population in Australia, the problem of alcohol and other drug (AOD) use by SSA youth has been reported in recent studies. Although evidence from other sociocultural contexts indicate that SSA cultural values could be protective against youth AOD use, not much is known about what pertains in the Australian context. The core justification for conducting this study is grounded on the awareness that people may perceive and conceptualize their heritage cultural values based on the sociocultural context in which they find themselves (Akkuş et al., 2017).

Objectives: To explore SSA …
