Silence Speaks Volumes - The Deaf Experience Of Mental Health, Culture And Communication, Otilia Rodrigues

University of Wollongong Thesis Collection 1954-2016

This thesis sets out to explore the world of deafness and to identify the major issues that beset deaf people. The experience of deaf people is largely unknown by the hearing world, partly because of the unimaginable nature of the reality of deafness (unlike blindness which, to some extent at least, can be easily simulated, though blindness from birth cannot), partly because deafness is not immediately visible and partly because the communication issues are so complex. The thesis begins with an historical view of deafness to provide a rationale for the way in which deaf people are understood and treated …

A Personal Development, Health And Physical Education (Pdhpe) Community Of Practice Responding To Curriculum Change, Deborah K. Clarke

University of Wollongong Thesis Collection 1954-2016

In 1999, the New South Wales Board of Studies (NSW BOS) released a revised Stage 6 Personal Development, Health and Physical Education (PDHPE) syllabus1. This syllabus signalled a significant discursive shift with subject knowledge altering to reflect a sociocultural perspective of health and physical activity. This shift challenged the identity of many Physical and Health Education teachers who have historically created their professional self around the scientific discourses of human movement.

Physical and Health Education teachers have been criticised for their lack of engagement with and insensitivity to the socio-cultural aspects of the revised syllabus (Gard & Wright, 2001; MacDonald …

The Development Of Radiolabelled Peripheral Benzodiazepine Receptor Ligands For Imaging Cancer And Neurodegenerative Disorders, Taryn P. Homes

University of Wollongong Thesis Collection 1954-2016

Three classes of compounds were chosen for investigation to find a high affinity and selective iodinated peripheral benzodiazepine receptor (PBR) ligand; indol-3-ylglyoxylamides, pyrazolopyrimidines, and pyridopyrrolooxazepines and pyrrolobenzoxazepines. These compounds were chosen from a literature search for their high PBR affinity and selectivity, ease of synthesis, and the potential for radioiodination.

Fifteen new halogenated N,N-dialkylindol-3-ylglyoxylamides were synthesised and tested for their PBR and central benzodiazepine receptor (CBR) affinity. The compounds IC50 values for the PBR ranged from 7.8 – 618 nM, and a structure activity relationship (SAR) was determined. Brominated compounds had higher binding affinities than their iodinated analogues, and indoles …

Recracking Of Jointed Rock Masses In The Sydney Basin, New South Wales, Australia, H. Memarian, C. L. Fergusson

Faculty of Science - Papers (Archive)

Fracture mapping of Late Permian – Early Triassic flat-lying sedimentary rocks in the Sydney Basin, New South Wales, Australia, shows that joints developed originally in extension were faulted in subsequent events. Joints with a regional distribution fall into two, early and late formed groups. Group I joints propagated horizontally and never interfered with each other. These joints were subsequently reworked or recracked. Recracking commenced with jointing and continued with lateral slip. Faulted joints grew horizontally by linking of recracked segments. En echelon arrays are the result of vertical propagation of faulted joints into intact rock. Recracking of rock also resulted …

Polypyrrole Based Switchable Filter System, Yanzhe Wu, Lorrain Nolan, Shirley Coyle, King Tong Lau, Gordon G. Wallace, Dermot Diamond

Faculty of Science - Papers (Archive)

BioTex is an EU funded project aiming to develop textile-based sensors for monitoring biological fluids. In the context of the project, there is a need to develop an effective sample delivery strategy for the wearable biomedical devices. A compact, electroactive switchable membrane would be useful as a valve to control the sample delivery within such devices. A method that employed inherently conducting polymers deposited onto a permeable substrate to form a switchable membrane was investigated [1, 2, 3]. By application of specific voltages, the permeability (pore size) of the membrane can be switched to swollen (expand) and contracted forms, which …

Chemical Vapour Deposition Grown Carbon Nanotubes For Interconnect Technology, R. W. Leahy, E. Lahiff, A Minett, W. J. Blau

Faculty of Science - Papers (Archive)

Multiwall carbon nanotubes have been grown by catalytic chemical vapour deposition using iron catalyst particles drop cast onto etched silicon wafers. The catalyst used was poly(styrene-vinylferrocene) in toluene solution which has an iron content of 2.1%. The etched silicon wafers have trench regions of varying widths ranging from 0.32 to 1 μm. For trench widths below 0.5 μm the number of “interconnecting” tubes growing from one side of the trench to the other increases sharply. A significant proportion of these “interconnects” are found to be Y-junction and multiple junction MWNTs. A systematic study of the effects of each of the …

Direct Imaging Of Lipid-Ion Network Formation Under Physiological Conditions By Frequency Modulation Atomic Force Microscopy, Michael J. Higgins, Suzi P. Jarvis, Takeshi Fukuma

Faculty of Science - Papers (Archive)

Various metal cations in physiological solutions interact with lipid headgroups in biological membranes, having an impact on their structure and stability, yet little is known about the molecular-scale dynamics of the lipid-ion interactions. Here we directly investigate the extensive lipid-ion interaction networks and their transient formation between headgroups in a dipalmitoylphosphatidylcholine bilayer under physiological conditions. The spatial distribution of ion occupancy is imaged in real space by frequency modulation atomic force microscopy with sub-Angstrom resolution.

2635 Ma Amphibolite Facies Gold Mineralisation Near A Terrane Boundary (Suture?) On Storo, Nuuk Region, Southern West Greenland, Allen P. Nutman, Ole Christiansen, Clark R. L Friend

Faculty of Science - Papers (Archive)

Gold on Storø (in the Nuuk region of southern West Greenland) occurs in a slice of strongly deformed, amphibolite facies, Neoarchaean quartzo-feldspathic metasedimentary rocks and amphibolites in tectonic contact with the Eoarchaean Færingehavn terrane and the Meso- to Neoarchaean Akia terrane. The gold is associated with either löllingite (FeAs) + arsenopyrite or pyrrhotite, which belong with the amphibolite facies silicate mineral assemblages. Zircons were U/Pb dated by SHRIMP to constrain the timing of mineralisation. The 2700–2830 Ma oscillatory-zoned, high Th/U volcano-sedimentary zircon as whole grains and cores are interpreted to give the maximum depositional age of the rocks hosting the …

Potential Roles Of Abundant Extracellular Chaperones In The Control Of Amyloid Formation And Toxicity, Mark R. Wilson, Justin J. Yerbury, Stephen Poon

Faculty of Science - Papers (Archive)

The in vivo formation of fibrillar proteinaceous deposits called amyloid is associated with more than 40 serious human diseases, collectively referred to as protein deposition diseases. In many cases the amyloid deposits are extracellular and are found associated with newly identified abundant extracellular chaperones (ECs). Evidence is presented suggesting an important regulatory role for ECs in amyloid formation and disposal in the body. A model is presented which proposes that, under normal conditions, ECs stabilize extracellular misfolded proteins by binding to them, and then guide them to specific cell receptors for uptake and subsequent degradation. Thus ECs and their receptors …

An Alternative Approach To Coal Mine Site Water Management: A Case Study On West Cliff Colliery, Antony Volcich, Stephen A. Short, Adrian C. Hutton, Robert John Morrison

Faculty of Science - Papers (Archive)

The provision of water supply, its usage and discharge, are major concerns for all mines, often accounting for a significant portion of the daily running costs. To reduce these costs, mines will collect as much site runoff as possible, and recycle the water whenever economically feasible. The constant recycling of on-site waters can mean that, over time, the levels of salinity, acidity or alkalinity, or other contaminants may build up within the internal water management system to a point which may lead to problems with licensed discharge requirements. This project investigated the water quality at West Cliff Colliery, in order …

Smart Nanotextiles: A Review Of Materials And Applications, Gordon G. Wallace, Danilo De Rossi, Yanzhe Wu, King-Tong Lau, Shirley Coyle, Dermot Diamond

These additional functionalities have numerous applications, encompassing healthcare, sports, military applications, and fashion. The wearer and the surrounding environment may be monitored in an innocuous manner, giving continuous updates of individual health status or environmental hazards. More generally, smart textiles become a critical …

Conducting Polymers With Fibrillar Morphology Synthesized In A Biphasic Ionic Liquid/Water System, J.M. Pringle, Orawan Ngamna, Carol M. Lynam, Gordon G. Wallace, Maria Forsyth, Douglas Macfarlane

Faculty of Science - Papers (Archive)

The synthesis of poly(pyrrole), poly(terthiophene), and poly(3,4-ethylenedioxythiophene) with unusual fibrillar morphologies has been achieved by chemical polymerization in a biphasic ionic liquid/water system. Use of aqueous gold chloride as the oxidant, with the monomers dissolved in a hydrophobic ionic liquid, allows the polymerization to occur at the ionic liquid/water interface. The resultant conducting polymer fibrils are, on average, 50−100 nm wide and can be thousands of nanometers long. The polymers produced in this ionic liquid system are compared to those synthesized in a biphasic chloroform/water system.

Reef Development At High-Latitudes During Multiple Interglacial Cycles: New Evidence From Lord Howe Island, Southwestern Pacific, David Kennedy, Colin D. Woodroffe, J -X Zhao

Faculty of Science - Papers (Archive)

Reef development during past Interglacial periods, when sea level and sea surface temperatures were higher than today, provide unique insights into how reef systems may respond to projected human-induced global warming. Lord Howe Island currently represents the southernmost limit of reef development in the Pacific. Reef growth of Pleistocene age has been inferred to have occurred around the island, and this paper provides the fi rst detailed descriptions on the character of this development. Two phases of reef growth are identifi ed, which occurred as isolated fringing reefs along the edge of the basaltic hills of the island. Uranium-series dating …

The State Of The Art Of Explosive Loads Characterisation, Alexander Remennikov

Faculty of Engineering - Papers (Archive)

This paper presents the state of the art of characterisation of explosive loads of engineering structures. In recent years, high explosive devices have become the weapon of choice for the majority of terrorist attacks. Such factors as the accessibility of information on the construction of bomb devices, relative ease of manufacturing, mobility and portability, coupled with significant property damage and injuries, are responsible for significant increase in bomb attacks all over the world. In most of cases, structural damage and the glass hazard have been major contributors to death and injury for the targeted buildings. Following the events of September …

Simulation Of Dynamic Recrystallization Using Irregular Cellular Automata, N Yazdipour, A Dehghan-Manshadi, C H. J Davies, P D. Hodgson

Faculty of Engineering - Papers (Archive)

Computer simulation is a powerful tool to predict microstructure and its evolution during dynamic recrystallization. Cellular Automata (CA), as one of the most efficient methods proposed to simulate recrystallization and grain growth. In this work, recrystallization and grain growth phenomena were modelled by using a two dimensional irregular CA method. Initial grain size, nuclei density and orientation of each grain were variables which have been used as entering data to the CA model. Final grain size, orientation of each grain, dislocation density and stress-strain curve were the results which have been resulted to validate the current model. Considering the model …

Analysis Of Particle Motion In A Micro-Fluidic Dielectrophoretic Device, Weihua Li, X Z. Zhang

Faculty of Engineering - Papers (Archive)

Interdigitated microelectrodes have found wide applications in manipulating and/or separating biological particles due to their simple structure and easy implementation. Particle behaviors in such interdigitated microelectrode devices are affected by a number of factors, including particle size, electrical potential, chamber geometry and dielectric properties. This paper presents systematical simulation study of particle behaviors in these devices by considering all these influencing factors. A case study is presented to separate different particles using both positive and negative DEP.

Multi-Stacked Artificial Muscle Actuator Based On Synthetic Elastomer, Huu Chuc Nguyen, Jongkil Park, Vu Thuy Doan, Hyun-Seok Kim, Ja Choon Koo, Youngkwan Lee, Jae-Do Nam, Hyouk R. Choi

Faculty of Engineering - Papers (Archive)

In this paper, we present a new artificial muscle actuator for the robotic applications, called multi-stacked actuator. This actuator is made from a new material, named synthetic elastomer previously developed by ourselves. The synthetic elastomer displays enhanced performance in terms of electrical as well as mechanical properties, which can be adjusted depending on its applications. The actuator is composed of the synthetic elastomer sheet coated with compliant electrodes on the both sides, connecting disks, spring, and rigid frame. This novel design enables the actuator to generate the large strain as well as the large force. Experimental works are performed to …

Marital Infidelity And Its Effect On Pathogen Diversity, Matthew J. Berryman

Faculty of Engineering - Papers (Archive)

Marital infidelity is usually examined solely in terms of strategies of men and women, with an emphasis on the enhanced payoff for male infidelity (provided he can get away with it). What are not clear are the strategies used, in terms of how often to engage in extra-marital affairs. It has been proposed that female strategies are governed by a “decision” to maximize the genetic diversity of her offspring, in order to better guarantee that at least some will survive against a common pathogen. This strategy would then impact on the strategies and diversity of pathogens. I make a number …

Classification Of Terahertz Data As A Tool For The Detection Of Cancer, Matthew J. Berryman, T. J. Rainsford

Faculty of Engineering - Papers (Archive)

The early detection of cancers is critical with respect to treatment and patient survival. Biopsy techniques that are currently employed for such diagnoses are invasive, time consuming and costly. A Terahertz (THz) imaging system potentially provides a fast and non-invasive way to detect and diagnose cancer. While there is proof of concept that THz can distinguish cancerous and normal tissue, the mechanisms underlying this differentiation are not well understood. A better understanding of THz spectral data can be gained through computational pattern recognition and related multivariate statistical tools. These allow for the differentiation of data into discrete and disjoint groups. …

Ti-Rich And Cu-Poor Grain-Boundary Layers Of Cacu3ti4o12 Detected By X-Ray Photoelectron Spectroscopy, C Wang, H J. Zhang, P M. He, G H. Cao

Faculty of Engineering - Papers (Archive)

Cleaved and polished surfaces of Ca Cu3 Ti4 O12 ceramics have been investigated by x-ray photoelectron spectroscopy (XPS) and energy dispersive x-ray spectroscopy (EDX), respectively. While EDX technique shows the identical Ca Cu3 Ti4 O12 stoichiometry for the two surfaces, XPS indicates that the cleaved surface with grain-boundary layers is remarkably Ti-rich and Cu-poor. The core-level spectrum of Cu 2p unambiguously shows the existence of monovalent copper only for the cleaved surface. Possible grain-boundary structure and its formation are discussed.

Banking On Housing; Spending The Home, Susan J. Smith, Beverley A. Searle, Nicole T. Cook

Faculty of Social Sciences - Papers (Archive)

British mortgagors hold more wealth in their homes than ever before. They are spending more freely from these assets now than they are likely to again. 'Banking on housing' is concerned with when, where, why and how people choose and use their mortgages to roll equity out of housing and into other things. It is a study of the consumption of housing, the consumption of mortgages, and the use of housing wealth in consumption more broadly.

Slash As Queer Utopia, Ika Willis

Faculty of Law, Humanities and the Arts - Papers (Archive)

In Text, John Mowitt writes that textuality can be understood “in terms of the interplay between what takes place within a cultural production… and what, as yet, has no place within the social”. In this paper I will be trying to tease out the complicated topography produced by this interplay between what takes place and what has no place, in its specific relation to the utopic and queer spaces produced by slash fan fiction. I argue that Mowitt’s understanding of the text allows us to interrogate and to reframe the relationship between textuality and historical/social context (often metaphorized as ‘situatedness’, …

Parents' And Adolescents' Perceived Influences And Barriers To Mental Health Services, Tim J. Wahlin

University of Wollongong Thesis Collection 1954-2016

Many young people with mental health problems do not seek professional help and remain at risk of suicide and adult psychopathology. The present research investigates the barriers that impede the help seeking of parents and their children and the sources of influence that assist young people to access clinical services. Study 1 uses archival data from a recent survey of non-clinical samples of young people between 15-25 years of age who attended Technical and Further Education (TAPE) colleges (n = 137) or accessed neighbourhood centres (n = 49). Respondents completed measures of psychological distress, suicidal ideation, perceived help seeking barriers …

Kiama: Its Region And Community 1901 To 1938, Elaine M. Dunn

University of Wollongong Thesis Collection 1954-2016

This thesis examines the Kiama region, its economics and the social progress of its environs during the years 1901 to 1938. It recognises the basic self-sufficiency and independent nature of the inhabitants and the individuality in rural and village life as it places the Kiama society within the context of a changing world. This *outside world* brought issues and influences that intruded into, and disturbed the simple on-going rhythm of the rural life. The thesis recognises the influence of the region-s geographical and environmental elements and the difficulties encountered by people in their attempts to advance and expand the dairying …

Financial Liberalisation In Sri Lanka: An Econometric Analysis, Ramsh Chandra Paudel

University of Wollongong Thesis Collection 1954-2016

This study examines the impact of financial liberalisation on macroeconomic issues such as saving, investment, financial performance, financial sector widening, gross domestic product, and the money demands of Sri Lanka over the time series annual data from 1963 to 2005. Financial liberalisation in Sri Lanka commenced in since 1977 with most of the effort being made up to 1995. This study is based on empirical analysis using the Ordinary Least Square (OLS) base Auto Regressive Distributed Lag (ARDL) approach of cointegration, and includes a causality test. This study contributes primarily where an evaluation of financial liberalisation impacts the financial liberalisation …

Seedling Establishment In An Pyrogenic Flowering Species: The Role Of Time-Since-Fire, Litter And Post-Dispersal Seed Predation, Andrew J. Denham

University of Wollongong Thesis Collection 1954-2016

In fire prone environments, the period immediately following fire events is perceived to provide the only opportunity for recruitment for many plant species. Resprouting shrubs do not need to recruit after every fire, because many individuals survive each fire and therefore may contribute to the population. However, without periodic recruitment, the accumulated mortality of adults both during and between fires would lead to local extinction even of these species. Most plant species establish seedlings within a year of fire from either canopy or soil seed banks. In contrast, species with pyrogenic flowering have no seeds available immediately after fire and …
