Isometric log ratios of proportions of major ions, derived from intuitive sequential binary partitions, are used to characterize hydrochemical variability within and between coal seam gas (CSG) and surrounding aquifers in a number of sedimentary basins in the USA and Australia. These isometric log ratios are the coordinates corresponding to an orthonormal basis in the sample space (the simplex). The characteristic proportions of ions, as described by linear models of isometric log ratios, can be used for a mathematical-descriptive classification of water types. This is a more informative and robust method of describing water types than simply classifying a water ...


Three Arcs: Observations On The Archaeology Of The Elands Bay And Northern Cederberg Landscapes, Alex Mackay Jan 2016

Three Arcs: Observations On The Archaeology Of The Elands Bay And Northern Cederberg Landscapes, Alex Mackay

Faculty of Science, Medicine and Health - Papers: part A

The area around Elands Bay and the adjacent interior landscapes west of the Doring River have been subject to intense archaeological investigation over the last ~50 years. The result is a region with great depth and diversity of archaeological information. In this paper I discuss three general observations that arise from the integration of data across this region. The first is that redundancy in site occupation is limited: even where many sites are excavated in a small area, understanding of the regional sequence cannot be assumed to be complete. The second is that humans did not live in rock shelters ...


A Teaching Model For Health Professionals Learning Reflective Practice, Joanne T. Joyce-Mccoach, Kylie Smith Jan 2016

A Teaching Model For Health Professionals Learning Reflective Practice, Joanne T. Joyce-Mccoach, Kylie Smith

Faculty of Science, Medicine and Health - Papers: part A

The aim of this work was to use the theory and concepts of critical reflection in the development of a teaching model to enhance the learning approach to reflective practice for health professionals. The results of this initial stage of a larger project have identified the key challenges for health professionals learning about reflective practice. From the literature a model for teaching critical reflection was conceptualized. It begins with an exploration of self and values, moves students through a dialogue with peers, and explores the social and historical contexts of practice. Conclusions drawn from this work show that despite the ...


Climatic Controls On The Global Distribution, Abundance, And Species Richness Of Mangrove Forests, Michael Osland, Laura Feher, Kereen Griffith, Kyle Cavanaugh, Nicholas Enwright, Richard Day, Camille Stagg, Ken W. Krauss, Rebecca Howard, James Grace, Kerrylee Rogers Jan 2016

Climatic Controls On The Global Distribution, Abundance, And Species Richness Of Mangrove Forests, Michael Osland, Laura Feher, Kereen Griffith, Kyle Cavanaugh, Nicholas Enwright, Richard Day, Camille Stagg, Ken W. Krauss, Rebecca Howard, James Grace, Kerrylee Rogers

Faculty of Science, Medicine and Health - Papers: part A

Mangrove forests are highly productive tidal saline wetland ecosystems found along sheltered tropical and subtropical coasts. Ecologists have long assumed that climatic drivers (i.e., temperature and rainfall regimes) govern the global distribution, structure, and function of mangrove forests. However, data constraints have hindered the quantification of direct climate-mangrove linkages in many parts of the world. Recently, the quality and availability of global-scale climate and mangrove data have been improving. Here, we used these data to better understand the influence of air temperature and rainfall regimes upon the distribution, abundance, and species richness of mangrove forests. Although our analyses identify ...


Raising Awareness Of Research Evidence Among Health Professionals Delivering Dementia Care: Are Knowledge Translation Workshops Useful?, Belinda J. Goodenough, Richard Fleming, Michael Young, Kim Burns, Cindy Jones, Fallon M. Forbes Jan 2016

Faculty of Science, Medicine and Health - Papers: part A

Providing information about the latest research via educational sessions to health professionals caring for people with dementia may be insufficient to drive change. This project explored self-reported impacts on practice change of adding information about knowledge translation (KT) to a national dementia education program. Six national workshop days were held. Each provided the option of participating in a Principles of KT and innovation implementation seminar in addition to a clinical topic update (sexualities and dementia, or managing behavioral and psychological symptoms of dementia). Six months postworkshop, 321 participants were invited to complete a research utilization survey. Seventy-five responded. KT seminar ...


Isolation And Structural Analysis Of The Covalent Adduct Formed Between A Bis-Amino Mitoxantrone Analogue And Dna: A Pathway To Major-Minor Groove Cross-Linked Adducts, Shyam K. Konda, Celine Kelso, Jelena Medan, Brad E. Sleebs, Don R. Phillips, Suzanne M. Cutts, J Grant Collins Jan 2016

Isolation And Structural Analysis Of The Covalent Adduct Formed Between A Bis-Amino Mitoxantrone Analogue And Dna: A Pathway To Major-Minor Groove Cross-Linked Adducts, Shyam K. Konda, Celine Kelso, Jelena Medan, Brad E. Sleebs, Don R. Phillips, Suzanne M. Cutts, J Grant Collins

Faculty of Science, Medicine and Health - Papers: part A

The major covalent adduct formed between a 13C-labelled formaldehyde activated bis-amino mitoxantrone analogue (WEHI-150) and the hexanucleotide d(CG5MeCGCG)2 has been isolated by HPLC chromatography and the structure determined by NMR spectroscopy. The results indicate that WEHI-150 forms one covalent bond through a primary amine to the N-2 of the G2 residue, with the polycyclic ring structure intercalated at the 5MeC3pG4/G10p5MeC9 site. Furthermore, the WEHI-150 aromatic ring system is oriented approximately parallel to the long axis of the base pairs, with one aliphatic side-chain in ...


Medication Management For People Living With Dementia: Development And Evaluation Of A Multilingual Information Resource For Family Caregivers Of People Living With Dementia, Robyn Gillespie, Pippa Burns, Lindsey Harrison, Amanda Ann Baker, Khin Than Win, Victoria Traynor, Judy Mullan Jan 2016

Medication Management For People Living With Dementia: Development And Evaluation Of A Multilingual Information Resource For Family Caregivers Of People Living With Dementia, Robyn Gillespie, Pippa Burns, Lindsey Harrison, Amanda Ann Baker, Khin Than Win, Victoria Traynor, Judy Mullan

Faculty of Science, Medicine and Health - Papers: part A

The aim of this chapter is to describe the development and evaluation of an online multilingual information resource focused on medication management, targeting people living with dementia and their family caregivers. Maintaining effective medication management is important to allow ongoing quality of life within the community setting and avoiding medication-related preventable hospitalisations for the person living with dementia. Family caregivers are likely to assume the role of medication management on behalf of the person in their care as dementia progresses. Little training or information is available to family caregivers to assist them with this role. A pilot online information resource ...


The Expanding Role Of Urban Fluvial Geomorphology: South Creek, Stephanie J. Kermode, Phillip Birtles, Geoff Vietz, Stephen Lynch, Jonathon Dixon, Carl Tippler, Michael Dean Jan 2016

The Expanding Role Of Urban Fluvial Geomorphology: South Creek, Stephanie J. Kermode, Phillip Birtles, Geoff Vietz, Stephen Lynch, Jonathon Dixon, Carl Tippler, Michael Dean

Faculty of Science, Medicine and Health - Papers: part A

As aspirations for waterways in urban areas increases, and we demand more social and environmental values from them, an increased role exists for applied geomorphology in urban streams of the future. Previously, there has been a strong focus on flood mitigation and water quality in stream management, and even where geomorphology has been used to drive legislation (e.g. stream order, offsets), desired outcomes have not always been achieved. Understanding how physical attributes of channels are altered by urbanisation, and how the physical template and waterways can assist in achieving aspirational goals, is now central to urban landscape managers and ...


Do Introduced Honeybees Affect Seed Set And Seed Quality In A Plant Adapted For Bird Pollination?, Amy-Marie Gilpin, Justin C. Collette, Andrew J. Denham, Mark K. J Ooi, David J. Ayre Jan 2016

Do Introduced Honeybees Affect Seed Set And Seed Quality In A Plant Adapted For Bird Pollination?, Amy-Marie Gilpin, Justin C. Collette, Andrew J. Denham, Mark K. J Ooi, David J. Ayre

Faculty of Science, Medicine and Health - Papers: part A

Aims: Worldwide, evidence suggests that exotic pollinators can disrupt plant mating patterns. However, few studies have determined if pollination by the honeybee Apis mellifera (the world's most widely introduced pollinator) reduces offspring quality when compared with pollination by native birds. The Australian Proteaceae provide an excellent opportunity to test the impact of honeybees in pollination systems that are adapted to birds and non-flying mammals.

Methods: We compared the frequency of flower visitation and foraging behaviour of birds and insects within seven populations of Banksia ericifolia. Banksia ericifolia is hermaphroditic and has large nectar-rich, orange inflorescences typical of bird and ...


Rural Health Professionals' Experiences In Implementing Advance Care Planning: A Focus Group Study, Sophie Fletcher, Craig Sinclair, Joel J. Rhee, Desiree Goh, Kirsten Auret Jan 2016

Rural Health Professionals' Experiences In Implementing Advance Care Planning: A Focus Group Study, Sophie Fletcher, Craig Sinclair, Joel J. Rhee, Desiree Goh, Kirsten Auret

Faculty of Science, Medicine and Health - Papers: part A

Advance care planning (ACP) is described as an ongoing discussion between a patient, their family and healthcare professionals (HCPs) to understand a patient's wishes for future health care. Legislation supporting ACP in Western Australia is relatively new and HCPs are still learning about the process and implementation. This study aimed to provide a rich description of rural health professionals' perceptions and experiences with ACP within the context of their professional role and to identify systemic issues and training needs. Ten focus groups were conducted throughout 2014 with a total of 55 rural participants including general practitioners (n≤15), general ...


The Thermal Dependence Of Na+ Flux In Isolated Liver Cells From Ectotherms And Endotherms, Paul Else Jan 2016

The Thermal Dependence Of Na+ Flux In Isolated Liver Cells From Ectotherms And Endotherms, Paul Else

Faculty of Science, Medicine and Health - Papers: part A

The thermal dependence (0-40°C) of Na+ flux in isolated liver cells of three endotherms (mice, rat and rabbit) was compared with that of ectotherms in the form of a thermally tolerant amphibian (cane toad), a cold-water fish (rainbow trout) and a thermophilic reptile (lizard). Mammals were found to share similar high rates of Na+ flux (3.0-3.7 nmol Na+ mg−1 protein min−1) at their normal body temperatures (36-39°C). These Na+ flux rates were significantly greater (P<0.0004-0.0001) than those of the ectotherms, which shared similar low rates of Na+ flux (0.7-1.3 nmol Na+ mg−1 protein min−1) at their very different normal acclimated body temperatures (15°C for trout, 25°C for toad and 37°C for the lizard species). Trout, which possess highly unsaturated membranes (similar to those of mammals), showed a Na+ flux with high thermal sensitivity at low temperatures similar to that found in mammals at higher temperatures. The thermal sensitivity of toad Na+ flux was significantly less (P<0.05-0.01) than that of rat and rabbit. Trout Na+ flux did not increase with increasing temperature much above 20°C, whereas all other species measured increased their Na+ flux with increasing temperature up to 40°C. In conclusion, at normal operating body temperatures, the rate of Na+ flux is much lower in ectotherms.

Alzheimer’s disease (AD) is one of the most prevalent neurodegenerative diseases, yet current therapeutic treatments are inadequate due to a complex disease pathogenesis. The plant polyphenol apigenin has been shown to have anti-inflammatory and neuroprotective properties in a number of cell and animal models; however a comprehensive assessment has not been performed in a human model of AD. Here we have used a human induced pluripotent stem cell (iPSC) model of familial and sporadic AD, in addition to healthy controls, to assess the neuroprotective activity of apigenin. The iPSC-derived AD neurons demonstrated a hyper-excitable calcium signalling phenotype, elevated levels ...


Nutritional Interventions For Survivors Of Childhood Cancer, Jennifer Cohen, Claire E. Wakefield, Richard J. Cohn Jan 2016

Nutritional Interventions For Survivors Of Childhood Cancer, Jennifer Cohen, Claire E. Wakefield, Richard J. Cohn

Faculty of Science, Medicine and Health - Papers: part A

Background Childhood cancer survivors are at a higher risk of developing health conditions such as osteoporosis, and cardiovascular disease than their peers. Health-promoting behaviour, such as consuming a healthy diet, could lessen the impact of these chronic issues, yet the prevalence rate of health-protecting behaviour amongst survivors of childhood cancer is similar to that of the general population. Targeted nutritional interventions may prevent or reduce the incidence of these chronic diseases. Objectives The primary aim of this review was to assess the efficacy of a range of nutritional interventions designed to improve the nutritional intake of childhood cancer survivors, as ...


The Industrial Revolution Kick-Started Global Warming Much Earlier Than We Realised, Helen V. Mcgregor, Joelle Gergis, Nerilie J. Abram, Steven J. Phipps Jan 2016

The Industrial Revolution Kick-Started Global Warming Much Earlier Than We Realised, Helen V. Mcgregor, Joelle Gergis, Nerilie J. Abram, Steven J. Phipps

Faculty of Science, Medicine and Health - Papers: part A

In the early days of the Industrial Revolution, no one would have thought that their burning of fossil fuels would have an almost immediate effect on the climate. But our new study, published today in Nature, reveals that warming in some regions actually began as early as the 1830s. That is much earlier than previously thought, so our discovery redefines our understanding of when human activity began to influence our climate.


Flowers In Australia: Phytochemical Studies On The Illawarra Flame Tree And Alstonville, Rudi Hendra, Paul A. Keller Jan 2016

Flowers In Australia: Phytochemical Studies On The Illawarra Flame Tree And Alstonville, Rudi Hendra, Paul A. Keller

Faculty of Science, Medicine and Health - Papers: part A

The first reported phytochemical studies on two species of flowers in Australia enabled the identification of six secondary metabolites from Illawarra flame tree flower (Brachychiton acerifolius) and seven secondary metabolites from the flowers of the Alstonville (Tibouchina lepidota). Pelargonidin 3-(6-coumarylglucoside)-5-(6-acetylglucoside) was found to be responsible for the red colour of B. acerifolius, whereas malvidin 3-(coumarylglucoside)-5-(acetylxyloside) was responsible for the purple colour of (T. lepidota) flowers. (2S)-4,5-Dihydroxyflavanone 7-O-β-d-glucuronide methyl ester was isolated for the first time from B. acerifolius, and its absolute configuration was determined by circular dichroism spectroscopy. Some of the traditional ...

Frontotemporal dementia (FTD) presents clinically with behavioral changes including disinhibition. Mutations in the tau-encoding MAPT gene identified in familial cases of FTD have been used to generate transgenic mouse models of the human condition. Here, we report behavioral changes in a recently developed P301S mutant tau transgenic mouse, including disinhibition-like behavior in the elevated plus maze and hyperactivity in the open field arena. Furthermore, histological analysis revealed the amygdala as a primary and early site of pathological tau deposition in these mice. Taken together, neuropathological and behavioral changes in P301S tau transgenic mice resemble features of human FTD.


Linking Pattern To Process In Reef Sediment Dynamics At Lady Musgrave Island, Southern Great Barrier Reef, Sarah Hamylton, Rafael Cabral Carvalho, Stephanie Duce, Chris M. Roelfsema, Ana Vila-Concejo Jan 2016

Linking Pattern To Process In Reef Sediment Dynamics At Lady Musgrave Island, Southern Great Barrier Reef, Sarah Hamylton, Rafael Cabral Carvalho, Stephanie Duce, Chris M. Roelfsema, Ana Vila-Concejo

Faculty of Science, Medicine and Health - Papers: part A

Linking surficial sediment patterns in reef environments to the processes that underlie their depositional dynamics enables predictions to be made of how environmental changes will influence reef-associated sedimentary landforms, such as islands and beaches. Geomorphic linkages between sediment deposition patterns and the biophysical processes that drive them are often poorly resolved, particularly at broad landscape scales where tangible statements can be made about structural changes to landforms. The present study applies geospatial techniques to link patterns in reef sediment dynamics at Lady Musgrave Island to the underlying processes driving them. In situ calcification is characterized by developing a high resolution ...


Preparation Of An Ion With The Highest Calculated Proton Affinity: Ortho-Diethynylbenzene Dianion, Berwyck L. J Poad, Nicholas D. Reed, Christopher Hansen, Adam J. Trevitt, Stephen J. Blanksby, Emily G. Mackay, Michael S. Sherburn, Bun Chan, Leo Radom Jan 2016

Preparation Of An Ion With The Highest Calculated Proton Affinity: Ortho-Diethynylbenzene Dianion, Berwyck L. J Poad, Nicholas D. Reed, Christopher Hansen, Adam J. Trevitt, Stephen J. Blanksby, Emily G. Mackay, Michael S. Sherburn, Bun Chan, Leo Radom

Faculty of Science, Medicine and Health - Papers: part A

Owing to the increased proton affinity that results from additional negative charges, multiply-charged anions have been proposed as one route to prepare and access a range of new and powerful "superbases". Paradoxically, while the additional electrons in polyanions increase basicity they serve to diminish the electron binding energy and thus, it had been thought, hinder experimental synthesis. We report the synthesis and isolation of the ortho-diethynylbenzene dianion (ortho-DEB2−) and present observations of this novel species undergoing gas-phase proton-abstraction reactions. Using a theoretical model based on Marcus-Hush theory, we attribute the stability of ortho-DEB2− to the presence of a barrier that ...

Cochrane, Rod Fensham, Meg A. Krawchuk, Owen F. Price, Victor Resco De Dios, Richard J. Williams, Ross A. Bradstock

Faculty of Science, Medicine and Health - Papers: part A

Most studies of climate change effects on fire regimes assume a gradual reorganization of pyrogeographic patterns and have not considered the potential for transformational changes in the climate-vegetation-fire relationships underlying continental-scale fire regimes. Here, we model current fire activity levels in Australia as a function of mean annual actual evapotranspiration (E) and potential evapotranspiration (E 0), as proxies for fuel productivity and fuel drying potential. We distinguish two domains in $E,{E}_{0}$ space according to the dominant constraint on fire activity being either fuel productivity (PL-type fire) or fuel dryness (DL-type fire) and show that the affinity to ...

This paper studies the seasonal variation of surface and column CO at three different sites (Paris, Jungfraujoch and Wollongong), with an emphasis on establishing a link between the CO vertical distribution and the nature of CO emission sources. We find the first evidence of a time lag between surface and free tropospheric CO seasonal variations in the Northern Hemisphere. The CO seasonal variability obtained from the total columns and free tropospheric partial columns shows a maximum around March-April and a minimum around September-October in the Northern Hemisphere (Paris and Jungfraujoch). In the Southern Hemisphere (Wollongong) this seasonal variability is shifted ...

Faculty of Science, Medicine and Health - Papers: part A

Background Difficulties in kneeling, one of the poorest scoring functional outcomes post total knee arthroplasty (TKA),have been attributed to a lack of patient education. This is the first study to investigate specific factors affecting a patient's perceived ability to kneel post TKA, following exposure to a preoperative kneeling education session. Materials and methods A cross-sectional study was conducted following TKA with patients who had been educated about kneeling prior to the operation. Patients completed kneeling questionnaires at 6 (n = 115) and 12 (n = 82) months post TKA. In addition to the 12-month kneeling questionnaire, patients also completed the ...

Situation Awareness: When Nurses Decide To Admit Or Not Admit A Person With Mental Illness As An Involuntary Patient, Christopher F. Patterson, Nicholas Procter, Luisa Toffoli

Faculty of Science, Medicine and Health - Papers: part A

Aim This paper will explore the application of situation awareness in nursing to determine its suitability as a framework to study how the decision to admit or not admit a person as an involuntary patient is made. Background The decision by a specially qualified nurse to admit or not admit a person to a mental health facility against their will remains a central component of contemporary mental health legislation. The decision has an impact on a person's autonomy and human rights. Conversely, the decision to admit may facilitate urgent assessment and treatment and ensure the safety of the individual ...

Faculty of Science, Medicine and Health - Papers: part A

The study of palaeo-chronologies using fossil data provides evidence for past ecological and evolutionary processes, and is therefore useful for predicting patterns and impacts of future environmental change. However, the robustness of inferences made from fossil ages relies heavily on both the quantity and quality of available data. We compiled Quaternary non-human vertebrate fossil ages from Sahul published up to 2013. This, the FosSahul database, includes 9,302 fossil records from 363 deposits, for a total of 478 species within 215 genera, of which 27 are from extinct and extant megafaunal species (2,559 records). We also provide a rating ...

Energetics Of Communal Roosting In Chestnut-Crowned Babblers: Implications For Group Dynamics And Breeding Phenology, Mark A. Chappell, William A. Buttemer, Andrew Russell

Faculty of Science, Medicine and Health - Papers: part A

For many endotherms, communal roosting saves energy in cold conditions, but how this might affect social dynamics or breeding phenology is not well understood. Using chestnut-crowned babblers (Pomatostomus ruficeps), we studied the effects of nest use and group size on roosting energy costs. These 50 g cooperatively breeding passerine birds of outback Australia breed from late winter to early summer and roost in huddles of up to 20 in single-chambered nests. We measured babbler metabolism at three ecologically relevant temperatures: 5°C (similar to minimum nighttime temperatures during early breeding), 15°C (similar to nighttime temperatures during late breeding) and ...

Identifying Spatial Variability And Complexity In Wetland Vegetation Using An Object-Based Approach, Christopher Owers, Kerrylee Rogers, Colin D. Woodroffe

Faculty of Science, Medicine and Health - Papers: part A

Coastal wetland vegetation is complex in form and function. Accurately mapping the spatial variation of vegetation complexity within these ecosystems is important for identifying areas of high conservation value that provide essential ecosystem services. In this study we delineate wetland vegetation, particularly mangrove and saltmarsh, to a vegetative morphological level that identifies spatial complexity in vegetation structure. This was achieved by integrating light detection and ranging (Lidar) and aerial imagery with an object-based approach. The results demonstrate that this is an effective methodology to identify vegetation complexity, with all study sites having greater than 90% classification accuracy. These high classification ...

An Investigation Of Future Fuel Load And Fire Weather In Australia, Hamish Clarke, Andy Pitman, Jatin Kala, Claire C. Carouge, Vanessa E. Haverd, Jason P. Evans

Faculty of Science, Medicine and Health - Papers: part A

We present an assessment of the impact of future climate change on two key drivers of fire risk in Australia, fire weather and fuel load. Fire weather conditions are represented by the McArthur Forest Fire Danger Index (FFDI), calculated from a 12-member regional climate model ensemble. Fuel load is predicted from net primary production, simulated using a land surface model forced by the same regional climate model ensemble. Mean annual fine litter is projected to increase across all ensemble members, by 1.2 to 1.7 t ha-1 in temperate areas, 0.3 to 0.5 t ha-1 in grassland ...

Balls Pyramid is a volcanic monolith rising 552 m from the Tasman Sea, 24 km southeast of the Pacific Ocean's southernmost modern coral reef at Lord Howe Island. High resolution seabed mapping of the shelf surrounding Balls Pyramid has revealed an extensive submerged reef structure in 30-50 m water depth, covering an area of 87 km2. Benthic community composition analysis of high-resolution still images revealed abundant scleractinian corals on the submerged reef, extending to a maximum depth of 94 m. Scleractinian coral occurred predominantly in 30-40 m depth where it comprised 13.3% of benthic cover within this ...

Soil sustainability implies maintaining the balance between soil erosion and production. While it is known how to assess soil erosion, only recently we have been able to estimate rates of soil and saprolite (namely regolith) production using uranium-series isotopes. This method assesses the time elapsed since rock-forming minerals start fractionating the U-series isotopes. In this study, we assess a sample pre-treatment protocol that has the potential to improve the method used to estimate regolith production rates. We propose that removal (or partial removal) of secondary phases precipitated from solution during pedogenesis (solution-derived phases) and organic matter from regolith may improve ...


Early Modern Human Lithic Technology From Jerimalai, East Timor, Ben Marwick, Christopher Clarkson, Sue O'Connor, Sophie Collins Jan 2016

Early Modern Human Lithic Technology From Jerimalai, East Timor, Ben Marwick, Christopher Clarkson, Sue O'Connor, Sophie Collins

Faculty of Science, Medicine and Health - Papers: part A

Jerimalai is a rock shelter in East Timor with cultural remains dated to 42,000 years ago, making it one of the oldest known sites of modern human activity in island Southeast Asia. It has special global significance for its record of early pelagic fishing and ancient shell fish hooks. It is also of regional significance for its early occupation and comparatively large assemblage of Pleistocene stone artefacts. Three major findings arise from our study of the stone artefacts. First, there is little change in lithic technology over the 42,000 year sequence, with the most noticeable change being the ...
