- Description: Excavating the ground for different purposes, such as extracting valuable materials or undertaking urban construction, may cause concerns regarding the stability of the formed slopes, which can affect the environment, the economy, and human lives. Slope stability analysis in large-scale and deep excavations such as open-pit mines is challenging due to uncertainties regarding varying material parameters, complex field conditions and lack of or insufficient data such as pore water pressure distribution, in-situ stress conditions, and discontinuities. Despite different advanced analytical and numerical slope stability techniques having been developed, slope stability analysis may produce unreliable conclusions due to these uncertainties and challenges. This study’s objective is to investigate the effect of different factors associated with slope stability through a case study of the Yallourn brown coal open pit mine in Australia. In this study, the two most common slope stability methods—the Limit Equilibrium Method (LEM) and the Finite Element Method (FEM)—were employed. A comprehensive study was conducted to determine how the generation and dissipation of Negative Excess Pore-Water Pressure (NEPWP) affect slope stability assessments. Additionally, due to the complex geological stratigraphy of the site, different scenarios for geological layering were defined and investigated for the slope stability analyses. Moreover, the sensitivity of the slope stability assessment to not only different material characteristics but also different formulations and assumptions of LEM and FEM are presented.

- Full Text:
- Description: Climate change, energy security, pollution and increasing unemployment in the face of automation are four critical challenges facing every region in the twenty-first century, including the Latrobe Valley in Victoria, Australia. The Valley – location of the largest brown coal deposits and forest industry in the southern hemisphere – is undergoing unprecedented and rapid changes. Its ageing brown coal power plants are retiring and replacements are not planned, leading to job insecurity. Solutions are needed that ensure continued economic activity in the region whilst allowing for the Valley to contribute its fair share in the fight against the climate change. The aim of this study is to investigate a possible local solution that could help tackle these issues of the Latrobe Valley in addition to plastic pollution and energy insecurity. Transitioning from linear to circular materials flow is one possible solution that favours sustainability and job security. Consequently, a multiproduct succinic acid biorefinery is modelled, acting as an industrial hub in a potential Latrobe Valley circular economy. This allows for employment creation in the value-addition of its platform chemicals into carbon negative and environment-friendly products. Additionally, such a biorefinery concept has the capacity to tackle Post-combustion CO2 Capture (PCC) industry’s wastes. It is anticipated that any future utilisation of brown coal as an energy vector would entail PCC to ensure carbon neutrality. A PCC industry produces CO2 and amine wastes that require adequate disposal. The modelled biorefinery has the capacity to valorise both. The simulation and the techno-economic analysis show the modelled Carbon Negative Biorefinery consumes 656,000 metric tonnes (t) of pulp logs and 42,000 t of CO2 to produce 220,000 t of succinic acid, 115,000 t of acetic acid and 900 t of dimethyl ether, annually. Biorefinery’s CAPEX and OPEX stand at AU$ 635,000,000 and $ 180,000,000 respectively. The calculated Minimum Selling Price for succinic acid is $ 990/t, only 6.4% higher than a typical biorefinery. Subsequently, biorefinery’s capacity as an anchor tenant is also simulated via technical evaluations of four value-added products: • Poly(butylene succinate) as biodegradable polymer replacing petro-plastics – simulation results show 1 t of succinic acid produces 0.19 t of tetrahydrofuran and 0.44 t of poly(butylene succinate); • Carbon fibre for insulation products, sporting goods and foams – 1 t of lignin and 0.8 t of acetic anhydride produce 0.8 t of carbon fibre; • Succinylated lignin adhesive for replacing urea-formaldehyde in the wood industry – simulation results show the biorefinery concept having the capacity to valorise both waste amine and CO2 from a PCC plant; and • Renewable fuels like hydrogen as energy vectors – a small biorefinery can potentially provide dozens of gigawatt hours of stored power for backup and peak demands, annually. In summary, results of this research are: • A biorefinery can valorise PCC plant wastes; • Multiproduct succinic acid biorefinery is economically viable; • Renewable fuels are ideally suited as energy storage vectors for a renewable energy grid both in developing and developed countries; • Bioproducts can reduce CO2 emissions thereby mitigate climate change; • Bioproducts can replace petro-products and reduce pollution; • Bioproducts can replace construction industry materials associated with CO2 emissions; • Biorefineries can help a region transition from a linear to a circular economy; and • Circular economies have the potential to generate secure jobs. In conclusion, this research identifies platform biochemicals as potential key drivers in a linear economy’s transition to a circular economy.

- Description: "This thesis investigates several non-linear analogues of Lagrange functions in the hope of answering the question 'Is it possible to generalise Lagrange functions such that they may be applied to a range of nonconvex objective problems?' The answer to this question is found to be yes for a particular class of optimization problems. Furthermore the thesis asserts that in derivative free optimization the general schema which is most theoretically and practically appealing involves the reformulation of both objective and constraint functions, whilst the least practically successful approach for everything but the most simple convex case is the augmented Lagrangian approach."

It takes a village to raise a family : designing desire-based community support with parents receiving a family service in south-west Ballarat
- Authors: Goff, Rachel
- Date: 2021
- Type: Text , Thesis , PhD
- Full Text:
- Description: In Victoria, Australia, the family services system is characterised by high referral rates and ongoing challenges to meet the needs of families who are experiencing risks and vulnerabilities. These issues are demonstrating the fact that there is a need to strengthen the level of community support that is being provided to children and their families prior to the escalation of their circumstances. Although the current neoliberal family services system has a key policy priority of reducing and managing family risk and vulnerability, it is neglecting to account for what families no longer want or are yet to experience. This is a shortcoming that the research study that is the subject of this thesis has addressed. In the context of a place-based, government–industry–university collaboration, this research study used a human-centred design methodology to engage with eight parents who were living in the south-west region of Ballarat, Victoria – an area characterised by socio-spatial disadvantage – and receiving a family service. This research study collected data over two phases of investigation. First, it explored the parents’ conceptualisations and experiences of community support in semi-structured interviews. Second, in a design workshop and post-workshop feedback and review interviews, it examined their views, priorities and recommendations for how their self-defined communities might support them in ways that would meet their own and their families’ needs. The research study found that parents conceptualise and experience community support as primarily informal, relational and bound to interpersonal characteristics such as reciprocity, trust, connection and belonging. It also found that their key priorities were supporting their children’s needs, their growing minds and their social skills, as well as bringing people together to promote equality. The parents who participated in this study proposed four recommendations: address the systemic constraints that are impacting on social cohesion; provide more opportunities for parents to support each other; provide non-judgemental and tailored services that can be accessed as a last resort; and enable greater self-determination, equality, trust and safety. These recommendations indicate that parents do not view community support as synonymous with risk and vulnerability; rather, they consider such support enables transformative change to occur in spite of it. Therefore, this research study has provided an understanding of the support that Victorian families want from their communities and has indicated that the paradigms that underpin the family services system are potentially incompatible with parents’ needs and desires.

Care leavers recovering voice and agency through counter-narratives
- Authors: Golding, Frank
- Date: 2021
- Type: Text , Thesis , PhD
- Full Text:
- Description: The publications in this thesis discuss recurring issues in the historical context of out-of-home Care (OOHC). They were written for various audiences but are arranged not by date of publication but thematically so as to present a coherent argument about the recovery of voice and agency by those who experienced OOHC. The thesis begins with an Overview which discusses autoethnographic and multi-layered approaches to history and shows how subject matter helps determine the choice of methodology and sources and, in turn, how methodologies influence the selection of sources and shape content. Authorities in Australia have a long history of removing children from their families when they are deemed to be neglected or ‘in moral danger’. Out of the public gaze, these children were often rendered silent, their voices simply unheard or deliberately supressed by the exercise of total institutional power. This thesis analyses how children were marginalised, cast as ‘the other’, and framed as deserving no better than they got. In the aftermath of a series of inquiries into institutional child maltreatment—some of which came about as a result of survivor advocacy and relied heavily on direct testimony—we now better understand children’s institutional experiences. In this changing environment, advocacy groups are effectively challenging the received accounts of historical Care. Their challenge has gained impetus from the opening up of records through rights legislation, especially access to personal case files. Large numbers of Care leavers have found their files inaccurate, incomplete, or misleading, and this discovery has stimulated many to produce compelling counter-narratives of the lived experiences of their childhood, and the living experiences that endure. The thesis concludes with an extended analytical commentary reflecting new interpretations of emerging histories, assessing changes in the status of Care leavers, and identifying directions warranting further development in OOHC.

An investigation of heat stress epidemiology, prevention guidelines, and sporting environment
- Authors: Gonsalves, Marlon
- Date: 2022
- Type: Text , Thesis , PhD
- Full Text:
- Description: As temperatures rise, the frequency of heatwaves, extreme summer heat and less night-time cooling increases. An uncontrolled increase in heat production affects performance and subsequently affects the health of the athlete resulting in exertional heat illness (EHI). EHI is a result of an uncontrollable rise in core body temperature arising from a thermoregulatory response. With rising temperatures, the risk of EHI when exercising or participating in sport increases. However, assessing the risk of EHI is contingent on accurate epidemiological data and addressing the risk of EHI is reliant on effective evidence-based interventions. This thesis assessed the risk of EHI through four interlinked studies: (ⅰ) an analysis of heat-related sports and leisure hospitalisations and emergency department presentations to determine trends in incidence rates and compare them with meteorological trends; (ⅱ) a document analysis of all sports and leisure activity heat-related injury prevention resources in Australia to develop an understanding of the content within those resources; (ⅲ) an investigation of surface temperatures of commonly used artificial sports surfaces to assess the risk posed by such surfaces and measure the differences in microclimates; and, (ⅳ) an assessment of the concordance of meteorological data of multiple artificial sports surfaces with meteorological data from the nearest Bureau of Meteorology (BOM) weather station and a local City of Ballarat (COB) environmental monitoring system (EMS). A total of 1055 heat injury hospitalisations and emergency department (ED) presentations were recorded between July 2008 and June 2018, which included 171 sport-related hospitalisations,139 ED presentations, 83 leisure-related hospitalisations and 662 ED presentations. There were significant correlations between ED presentations for heat-related sports injuries and mean, minimum and maximum temperature, mean and maximum temperature anomaly, summer maximum temperature, and summer maximum temperature anomaly. Three overarching categories emerged through the document analysis process: preventive strategies (n=299, 63.9%), risk factors (n=94, 20.1%), and treatment (n=75, 16.0%). Activity modification, which included information on rescheduling games and extra breaks, was the most common intervention. Cricket, soccer, swimming, and triathlon had the most complete set of heat resources. During the 2020–2021 summer period a total of 1245 measurements were recorded across five artificial sports surfaces: athletics, hockey, lawn bowls, soccer, tennis. The lawn bowls turf was the hottest surface with a mean surface temperature of 54.43 (± 13.46) °C. An increase in surface temperature corresponded to an increase in air temperature, wet bulb temperature and a decrease in relative humidity but the effect varied across the five surfaces. An increase in solar radiation and air temperature also corresponded to an increase in surface temperature. On all five surfaces measured, the BOM air temperatures were the lowest, followed by the on-site air temperatures and then the COB air temperatures on all surfaces. The highest Wet Bulb Globe Temperature (WBGT) measurements of 24.38 (± 2.39) °C were recorded by the COB sensor, while the lowest WBGT measurements 20.76 (± 1.99) °C were recorded by the BOM. There was a statistically significant difference in the WBGT categorisation between on-site estimate measurements and BOM measurements, p <0.001. The incidence of heat-related hospitalisations and ED presentations provides a baseline from which heat-related guidelines and interventions can be developed, evaluated, and modified. Heat resources considered in the document analysis suggest EHI is preventable if appropriate precautions are implemented. With a focus on preventing EHI, heat resources mainly provided recommendations on modifying activities and reducing exposure to extreme conditions. These results imply the EHI risk posed by artificial sport surfaces are not uniform and safety polices should be updated to reflect the link between air temperature and surface temperature. Understanding how surface temperature is influenced by air temperature, solar radiation and cloud cover allows for more accurate predictions of playing conditions on these artificial sport surfaces. Differences were observed between the individual meteorological measurements, the WBGT measurements and the heat stress categorisation. Overall, a significant discord existed for both individual meteorological variables and WBGT modelled from multiple sources of available data. The findings from this thesis have implications for athlete welfare and strengthening future interventions. Overall, this doctoral research project quantifies the scale of heat-related injuries, reviews the policies to address these heat-related injuries and provides new knowledge on the risk posed by artificial sports surfaces.

Legitimising harm : A critical ethnography of gambling in a community
- Authors: Greenslade, Deborah

- Type: Text , Thesis , PhD
- Full Text:
- Description: This thesis reports on a community study which explored the relationship between a small rural community and its club based poker machines. That enquiry aimed to broaden the general research focus from the dominant conceptualisation of individual gambling pathology to a community-level analysis. The theoretical and epistemological stance was also shifted, away from positivism (with its focus on measurable cause/effects), towards a critical constructionist approach. Employing ethnography, the research comprised extended community engagement, observation, document analysis and 51 individual interviews. Critical theory was applied to issues of ideology, discourse and power associated with poker machine gambling within the macro sociopolitical and local community contexts. The study found that, despite significant opposition, poker machines inveigled their way into this community with the support of powerful economic and political forces and influential club members. Location of the machines within an established club embedded them within networks of community relationships. Disbursement of community benefit ensnared many community members as beneficiaries of poker machine losses and rendered them complicit in gambling harms. The research identified that at times community ideology and interests acted as a powerful force against the establishment and expansion of poker machine gambling. Conversely, community ideology and interests also acted to legitimate the presence and operation of poker machines and to suppress opposition. This reflects the complex and contested nature of the construct of community. Reproduction of dominant gambling discourses, including those which frame gambling harm as pathology and an issue of individual responsibility, operate to conceal and condone gambling harms.

- Description: This thesis reports on a community study which explored the relationship between a small rural community and its club based poker machines. That enquiry aimed to broaden the general research focus from the dominant conceptualisation of individual gambling pathology to a community-level analysis. The theoretical and epistemological stance was also shifted, away from positivism (with its focus on measurable cause/effects), towards a critical constructionist approach. Employing ethnography, the research comprised extended community engagement, observation, document analysis and 51 individual interviews. Critical theory was applied to issues of ideology, discourse and power associated with poker machine gambling within the macro sociopolitical and local community contexts. The study found that, despite significant opposition, poker machines inveigled their way into this community with the support of powerful economic and political forces and influential club members. Location of the machines within an established club embedded them within networks of community relationships. Disbursement of community benefit ensnared many community members as beneficiaries of poker machine losses and rendered them complicit in gambling harms. The research identified that at times community ideology and interests acted as a powerful force against the establishment and expansion of poker machine gambling. Conversely, community ideology and interests also acted to legitimate the presence and operation of poker machines and to suppress opposition. This reflects the complex and contested nature of the construct of community. Reproduction of dominant gambling discourses, including those which frame gambling harm as pathology and an issue of individual responsibility, operate to conceal and condone gambling harms. These discourses marginalise and disempower community members harmed by gambling, while legitimating the club’s deployment of poker machines. This has helped to maintain existing arrangements and to support the shared and powerful interests of the state, the gambling industry, and venues.

Shelter From the Storm. Webs of connectedness and entanglement in contemporary painting of the everyday
- Authors: Griffin, Tony
- Date: 2021
- Type: Text , Thesis , PhD
- Full Text:
- Description: Considering the often-overlooked objects in a single Australian suburban home through the practice of still life painting, this project examines the everyday as a means to understand our anxious times. By employing phenomenological approaches this project explores the theoretical understandings of the everyday and many recent iterations of “thing theory”. Through the practice of still life, its traditions, language and its contemporary currency, painting is employed as a means to understand this age of anxiety. My research closely observes, documents and presents the everyday objects in a single suburban Australian home in the early part of the twenty-first century. Ian Hodder’s theory of entanglement and the mutual dependency between humans and things that it proposes, is considered as a suitable tool for a contemporary visual art practitioner in creating new understandings of our domestic and broader world. Additionally, my research employs the innovative and challenging approaches to the familiar championed by the French writer Georges Perec. His work in revealing an understanding of our world through the exhaustively comprehensive and meticulous description of everyday things provides a structural basis for this project. Our homes are where we experience the everyday nature of our existence most keenly and my home is not unlike the homes of others. It is a place that shares those broader ideals considered to constitute a home, my shelter and my refuge. It is a worthy place in which to seek an understanding of our complex world. This project reveals in paint my observations of the minor things which, when combined, constitute the major things in my small home. The result of these observations is a series of representations of a familiar environment that enables an audience to recognise their own surroundings and re-evaluate the many hidden entanglements in their world in more complex and evocative ways.

Mine evaluation optimisation
- Authors: Grigoryev, Igor
- Date: 2019
- Type: Text , Thesis , PhD
- Full Text:
- Description: The definition of a mineral resource during exploration is a fundamental part of lease evaluation, which establishes the fair market value of the entire asset being explored in the open market. Since exact prediction of grades between sampled points is not currently possible by conventional methods, an exact agreement between predicted and actual grades will nearly always contain some error. These errors affect the evaluation of resources so impacting on characterisation of risks, financial projections and decisions about whether it is necessary to carry on with the further phases or not. The knowledge about minerals below the surface, even when it is based upon extensive geophysical analysis and drilling, is often too fragmentary to indicate with assurance where to drill, how deep to drill and what can be expected. Thus, the exploration team knows only the density of the rock and the grade along the core. The purpose of this study is to improve the process of resource evaluation in the exploration stage by increasing prediction accuracy and making an alternative assessment about the spatial characteristics of gold mineralisation. There is significant industrial interest in finding alternatives which may speed up the drilling phase, identify anomalies, worthwhile targets and help in establishing fair market value. Recent developments in nonconvex optimisation and high-dimensional statistics have led to the idea that some engineering problems such as predicting gold variability at the exploration stage can be solved with the application of clusterwise linear and penalised maximum likelihood regression techniques. This thesis attempts to solve the distribution of the mineralisation in the underlying geology using clusterwise linear regression and convex Least Absolute Shrinkage and Selection Operator (LASSO) techniques. The two presented optimisation techniques compute predictive solutions within a domain using physical data provided directly from drillholes. The decision-support techniques attempt a useful compromise between the traditional and recently introduced methods in optimisation and regression analysis that are developed to improve exploration targeting and to predict the gold occurrences at previously unsampled locations.

DSM-IV AD/HD symptoms: Prevalence, gender and age differences, and construct validity of parent and teacher ratings of Malaysian children
- Authors: Hafetz, Nina
- Date: 2007
- Type: Text , Thesis , PhD
- Full Text:
- Description: Attention-deficit/hyperactivity disorder (AD/HD) is marked by deficits in attention, hyperactivity and impulsivity (American Psychiatric Association, 1994). The current DSM-IV conceptualisation of AD/HD as comprising of separate, but related, Inattention (IA) and Hyperactivity/Impulsivity (H/I) dimensions have been supported in confirmatory factor analytic (CFA) studies. Despite being one of the most extensively studied childhood disorder, there is a lack of research on AD/HD in non-western populations. Research on AD/HD in Asian countries, particularly, is limited. To date, no study has comprehensively investigated the characteristics of AD/HD in a Malaysian sample. The current study had 4 major aims. The first aim of the study was to investigate how the IA and H/I symptoms groups vary by age, gender, and age by gender interaction. The second aim of the study was to obtain prevalence rates of DSM-IV AD/HD and the three subtypes (i.e., Predominantly Inattentive Type, AD/HD-IA; Predominantly Hyperactive/Impulsive Type, AD/HD-H/I; and Combined Type, AD/HD-C) within this population. This was examined for boys and girls separately, and together. The third aim of the study was to investigate the internal validity of DSM-IV AD/HD using single source confirmatory factor analysis (CFA), while the fourth aim of the study was to examine trait, source and error variance of the AD/HD symptoms using the CFA multitrait (IA and H/I) by multisource (parent and teacher) approach (CFA MT-MS). All the CFA and CFA MT-MS analyses were conducted separately for boys and girls and used scores recoded via the binary method, as opposed to the ordinal scoring method. The sample consisted of 934 Malaysian schoolchildren aged 6-12 years (436 boys: mean age 8.86 years; and 498 girls: mean age 9.02 years) [...] There was more source than trait variance for parent rated H/I and teacher rated IA for girls. Unique to the current study is the use of binary as opposed to ordinal data to run the CFA and MTMS analysis. The implications of the findings for the conceptualisation, assessment, treatment, psychometric properties of AD/HD rating scales and the recognition of AD/HD in the Malaysian population are discussed. Suggestions for future research are offered.

Framed by reconciliation : Reading cross-cultural space in early twenty-first century Australian literature
- Authors: Hall, Demelza
- Date: 2015
- Type: Text , Thesis , PhD
- Full Text:
- Description: This thesis analyses literary works by Indigenous and non-Indigenous Australian writers, focussing on the production and function of space in scenes of constructive cross-cultural interaction. All of the novels examined can be read as pedagogies of reconciliation due to their engagement with – and subversion of – the goals, processes, issues, and outcomes of the 1990s reconciliation movement. Yet, while these texts are all broadly framed by reconciliation, this thesis argues that it is their commitment to reimagining spaces of home which marks them as particularly productive reconciliatory pedagogies. One of the primary assertions of this thesis is that for reconciliatory discourses to become useful pedagogies – to educate and inspire and connect people, rather than just inform and unsettle – they need to create spaces of hope. Home became a contested site during the reconciliation years, with processes of historical revisioning and reports such as Bringing Them Home forcing a reconsideration of what it might actually mean to be at home. By moving away from traditional domestic spaces and staid conceptions of dwelling, these narratives attempt to heterogeneously reconfigure notions of home and nation. This thesis is organised around specific spaces and spatial metaphors, and the critical paradigms informing them. Chapter 2, for example, examines ways in which the metaphor of ‘the Gap’ structures ideas of intercultural exchange in reconciliatory discourse and postcolonial criticism. Chapter 3 – which analyses Kate Grenville’s The Secret River and Vivienne Cleven’s Her Sister’s Eye – focusses on the space of the colonial homestead and how it is used to frame notions of impasse, or unbelonging. Chapter 4 examines a series of “interspaces” and how “dwelling-in-motion” frames cross-cultural transformation in Alex Miller’s Journey to the Stone Country, Gail Jones’s Sorry and Alexis Wright’s Carpentaria. Moving away from traditional conceptions of home, Chapter 5 analyses how heterotopic spaces are deployed to frame scenes of exile in Alexis Wright’s Carpentaria, Tim Winton’s Dirt Music and Richard Flanagan’s Gould’s Book of Fish. Chapter 6 explores how conceptions of being in country frame notions of belonging and well-being in Alex Miller’s Landscape of Farewell and Kim Scott’s That Deadman Dance. Finally, in conclusion, Chapter 7 suggests that spaces of hope can emerge in reconciliatory discourses when home, like nation, is recognised as a site of entanglement.

Patricia Violet Slater : a remarkable leader in the nursing profession in changing times
- Authors: Hamilton, Helen
- Date: 2021
- Type: Text , Thesis , PhD
- Full Text:
- Description: Patricia Slater opposed the entrenched traditional system of educating nurses in hospital programs and, in the years 1960-1983, she was an advocate and activist for tertiary level ducation for nurses in the general education system. Ms Slater’s educational expertise and unique position in nursing affairs, positioned her to progress nursing education at both undergraduate (basic) and graduate (post basic) levels and to take a leading role in the reform of nursing education. In this biographical account of Ms Slater’s professional life, her contribution as a pioneer and key player in the late twentieth century radical reform of nursing education, is distinguished from the collective activity of the nursing profession. The 1950s-1970s, highlighted many shortcomings in nursing practice drawing attention to the inadequacy of the contemporary preparation of nursing students. The traditional nursing education system, couched as it was in the cultural ethos of nineteenth century and rule driven, is identified as a major contributing factor to the apparent stasis in educational growth and development in Nursing. Social, cultural and political ideologies, to which the nursing profession was subject, worked to constrain and contain the profession, contributing to the apparent powerlessness of the profession to readily adjust and rectify its position. Chief among these influences was firstly, the domination and control of the medical profession over the health system and all health matters. Secondly, paternalism, that kept women in society and in the workforce subordinate to men. Thus nurses, being mostly female, were also professionally subordinated in the workplace being subject to medical control and direction. Thirdly, the Nightingale legacy of discipline and obedience in combination with the apprenticeship model of nurse education and the hierarchical organisation of nursing work, combined to encourage passive and conservative traits in nursing students that persisted over time. Ms Slater returned from nursing studies in America in 1960 with a vision as to how the nursing profession in Australia could advance and prepare nurses able to carry the profession forward, to determine the role and function of the nurse and the education required to develop nursing students at all levels. It would not be until the 1970s that sufficient numbers of nurses were ready to support the radical solution that Slater advocated, the transfer of nursing education into the general education system. Achieving this aim drew support from leading nursing organisations and the profession’s collective effort, sustained for over a decade, ultimately proved successful. Ms Slater’s thinking on nursing education, her vision for the nursing profession’s future, her philosophy and values in respect of Nursing, are drawn from her published work and some unpublished papers. Finding little to give insight into her personal reactions to events in her professional life, I approached individuals who had worked with Ms Slater ranging in time from approximately 2-12 years. Sixteen individuals were interviewed to gain their perspectives on events and their views and perceptions of Ms Slater: all but four were former employees. Interviews were taped verbatim, transcribed and reviewed by participants, all of whom agreed to be identified in the study. The official records of the College of Nursing, Australia and the then Royal Australian Nursing Federation, provided further primary source material together with the many reports of inquiries into nursing education. A diverse range of material was used to place Ms Slater’s life and the Nursing profession as a whole, in the social, cultural and political context of the times. Nursing in Australia was compared with like countries in the same time period. It was established that all were facing similar problems for much the same reasons. Patricia Slater’s leadership and expertise, were essential components in the successful achievement of tertiary level education for nurses. As a result, in the years 1984-1994, the nursing profession moved from a skilled craft towards becoming a knowledge based discipline, the equal of other health professions. The change in nurse education at that time, was as radical as that introduced to Australia by the Nightingale nurses in 1860s, in that the position and status of nurses and Nursing was radically changed on both occasions. The story of one of the most important Australian nurse leaders of the twentieth century is related for the first time in this work.

Misogynology and the impossibility of dwelling
- Authors: Hammond, Richard
- Date: 2017
- Type: Text , Thesis , PhD
- Full Text:
- Description: For Martin Heidegger, the essence of technology—Ge-stell—is a framing and ordering of the world that valorises instrumental-calculative thinking at the direct expense of other forms of thought. As being-in-the-world—a notion that the later Heidegger would re-interpret as belonging-to Being as the mortal of the fourfold—human being is given over to the logos of framing and ordering: technology. In the technological age, human being is ordered into an inauthentic relationship with itself, its environment, and with Being itself. Yet the gatheringsaying of the modern logos is more than a framing of the cosmos into standing reserve, it is also a peculiarly gendered framing of human being. In this thesis I claim that while Heidegger was oblivious to the inherently masculinist aspect of the Western tradition, his thought provides an effective theoretical basis to interrogate invisible systemic gender inequality. In order to demonstrate this I develop an account of Heidegger’s critique of technology by tracing the origins of the critique from Heidegger’s early thinking in Being and Time onwards. This genealogical approach demonstrates the centrality of Heidegger’s critique of technology to his broader project, and facilitates an exploration of the fourfold as a heuristic from which an originary sense of Being (as dwelling) can emerge. By employing Heidegger’s critique of technology to highlight the metaphysical assumptions that frame mainstream debates on pornography, I demonstrate that the pornification of popular culture—now largely synonymous with rape culture—can be interpreted as a significant aspect of the logos of Ge-stell. I argue that rather than remain the purview of masculine privilege, the seeming impossibility of dwelling in the modern age reveals the techno-misogynological framing of Ge-stell.

- Description: The primary aim of this thesis is to contribute to ongoing historical research into migration to and settlement in Australia by Scots. It achieves this by identifying and examining letters sent from the colonies in New South Wales which were printed in historic Scottish newspapers between 1820 and 1850. In examining the material, this thesis argues that the letters had potential to influence emigration decisions by Scots. The study shows some of the ways in which New South Wales was reported in the Scottish press and compares those reports with conditions in Scotland at the time. The comparisons and analyses of the letters, with consideration of their authors and likely readers as well as the newspapers in which they were printed demonstrate that the letters did have potential to influence emigration decisions. Its particular contribution to knowledge arises from demonstrating how mostly private letters which became publicly available through publication in newspapers had potential to influence emigrants’ decisions about moving to Australia. Rather than claiming direct evidence of the publication of particular letters as having influenced emigration, it shows how reporting of conditions in Australia when set into a context of contemporary events and conditions in Scotland had potential to influence decisions. It is grounded in the body of historical research about colonial Australia and sits within this Australian historiographical context. Given the motivations and attractions of Scots to colonial Australia this thesis also engages with techniques and theoretical approaches associated with Scottish diaspora studies, an area of research that often emphasises other Scottish migration patterns to Canada, New Zealand and the USA. When considered together both of these historiographical approaches lend themselves to primary source material analysis and a methodological approach that this doctoral study uses to examine the motivations of Scots who migrated to colonial Australia.
