- Description: Terrestrial Water Balance (TWB) incorporates the combined effects of precipitation and evaporation, and is an important factor influencing agricultural and hydrological processes and management. This study analyses the TWB components at five stations in central Victoria from 1972 - 2013, a region which spans a range of agricultural and hydrological regimes. These stations represent distinct climatic and geographic locations including the dry inland plains, the Great Dividing Range and the southern coastal area. This research focuses on the „Growing Season‟ from March - November; a period where increased availability of moisture is critical for commencing, maintaining and ceasing a variety of agricultural practices. Moisture surplus is known as „Effective Precipitation‟ and is represented by a Precipitation/Evaporation (P-E) ratio >1. Whilst the combined P-E ratio is significant, an emphasis is placed upon examining individual meteorological components which determine the TWB. Hence rainfall and pan evaporation characteristics are analysed on both monthly and seasonal timescales within the 'Growing Season'. Trends in rainfall are fairly consistent across all stations with ongoing declines generally observed in all months except November, most notable in April, May and October. Pan evaporation displays much more variation between stations with both strong positive and negative trends evident throughout the station network in each season. The varying trends in pan evaporation between the stations suggest that the same large scale conditions can result in vastly different effects locally, owing to topographic and geographic factors. The influence of El Niño - Southern Oscillation (ENSO) and Indian Ocean Dipole (IOD) on pan evaporation is widespread and statistically significant during Winter and Spring. The Southern Annular Mode (SAM) displays marked intra-seasonal influence which appears to be highly location dependent. Consistent with the literature, rainfall shows increasing correlations with ENSO and IOD through Winter before peaking in Spring at all stations. Interestingly, despite changes in teleconnection strength over time, these tropical climate drivers display a stronger relationship with pan evaporation than rainfall over the full analysis period. Therefore an opportunity may exist to use such relationships to develop seasonal forecasts of evaporation, similar to what is currently employed for seasonal rainfall forecasting. This is important as Effective Precipitation is significantly influenced by the evaporative component of the TWB. Critically, this study shows that variations in such elements need to be considered on a regional basis, bearing in mind differences in geographic and topographic location, as well as intra-seasonal regimes within the overall Growing Season.

- Description: The idea that experiencing the world is a straightforward uncomplicated matter is challenged in a contemporary postmodern context. The empirical notion that reality can be experienced firsthand has been mostly abandoned in favour of the view that reality is constructed through language and culture. Indeed, most views of the world carry a bias, whether conscious or unconscious, which affects all that is encountered. It is not possible to separate the observable world from the person observing it nor to report on the world without already having a position on how it functions. As such ‘meaning’, in this body of research, is found in the awareness that the past informs and shapes the experience of the present moment. This is activated through a heightened sensory awareness of various stimuli, set up through the artworks, which draw distant, past associations into the present consciousness. Through practice led research I am creating the conditions within which the visitor can develop a heightened awareness of their associations through sensory experience and discover that those associations are always tethered to the past, shaping the ways in which they encounter the world. It is my objective through this project to open the way for a better understanding of the Self in relation to Being (consciousness), in a phenomenological sense, through this heightened sensory awareness. The practical outcomes of this research have been developed through a creative exploration of the sensorial world. In this project I posit that we do not draw meaning from the physical, material world itself but rather, meaning is located in our understanding that the physical world is brought into being through our consciousness of it.

- Description: The principal aim of this research thesis has been to reconstruct the life and times of Dr Hermann Beckler (1828-1914), a Bavarian-born scientist and adventurer who spent six years in Australia between 1856 and 1862. This study constitutes the first authoritative analysis of Beckler’s life. It focuses on the various turning points that influenced his odyssey-like journey from Bavaria to Australia and back again, as well as his travels within Australia, his interest in the natural environment and the botany of Australia, and his empathy towards the Indigenous people. Beckler was a product of the Age of Romanticism. He was an enigmatic and contemplative person, yet possessed a degree of toughness and resilience to overcome what appeared to be initially a self-imposed exile, replete with self-recriminations, as he tried to establish himself, firstly as a medical doctor and then as a pharmacist in the pioneering Moreton Bay region of colonial New South Wales. His interests in the natural sciences provided a solution to the problem of employment, and his botanical collecting skills ultimately gained him a position with Dr Ferdinand Mueller of the Melbourne Botanic Gardens. He worked as a botanical plant collector in northern New South Wales before his medical qualifications and botanical saw him appointed as medical doctor and botanist to the Victorian Exploring Expedition 1860-1861 led by Robert O’Hara Burke and William John Wills. Beckler recognized this appointment as an opportunity to explore the hitherto unknown parts of the interior of Australia and while he did his best to fulfill his role, he was frustrated by the mismanagement of the whole expedition by Burke’s erratic leadership and by the ineptitude of the Royal Society of Victoria’s Exploration Committee. He remains one of Australia’s and Germany’s forgotten explorer botanists. This thesis aims to bring to life Beckler’s contribution to this important episode in Australian colonial history.

The use of on-farm water points and artificial wildlife ponds in providing habitat for fauna in the Wimmera and Southern Mallee, Victoria, Australia

- Description: Fauna living in arid environments face strong ecological and physiological constraints. Water is the key requirement and vertebrates exhibit a range of adaptations for survival. Some species obtain water from their diet, but those which require water to drink or as habitat must either live in or near permanent water, or move in search of water. This strongly influences the distribution and abundance of vertebrate species in arid environments. In arid agricultural landscapes, the development of artificial water sources for stock has benefited water-dependant native fauna, particularly frogs. Little is known about the effects of removal of artificial water sources in these environments. In North-western Victoria, completion of the Northern Mallee Pipeline and the proposed construction of the Wimmera Mallee Pipeline will ultimately replace over 20,000 farm dams, resulting in the widespread loss of an open water resource currently used by fauna across the Wimmera and southern Mallee. The wildlife values of the different on-farm water points in the Northern Mallee Pipeline region and the remaining Wimmera Mallee Domestic and Stock Channel System were examined. Species richness and abundance of vertebrates were surveyed at farm dams, channels and stock troughs in open paddocks, and at farm dams in Mallee woodlands. Mallee woodlands with no available water were also surveyed. Sites were surveyed once per season to determine which species were utilising the different on-farm water points and Mallee woodlands. Knowledge of their usage by different species allowed the importance of each water point type to be determined and the impact of the closure of the channel system to be assessed. The study recorded 57 vertebrate species in the Northern Mallee Pipeline region, including six reptile, 43 bird, seven mammal and zero frog species. Surveys in the Wimmera Mallee Channel/dam region recorded 74 different species, including three reptile , 57 bird, eight mammal and six frog species. Overall species richness and abundance was highest at sites with a farm dam in a Mallee woodland, and the levels of species richness and abundance were significantly higher than at sites with Mallee woodland and no available water. The differences between the two site types were due mainly to greater abundance of water- dependant species at farm dams in Mallee woodland sites. For water points in open paddocks, species richness and abundance was highest at sites with a farm dam in an open paddock and lowest at sites with a stock trough in an open paddock. The difference between the different open paddock water point types were significant, and like woodland sites, were driven by greater numbers of water-dependant species. The study also examined whether purpose-built artificial wildlife ponds could provide habitat for water-dependant fauna and whether artificial wildlife ponds could potentially maintain fauna populations after de-commissioning of the existing channel system. The results of this study showed that artificial wildlife ponds placed in Mallee woodlands can provide habitat for birds, both in the Northern Mallee Pipeline region and the Wimmera Mallee Channel/dam region. The results also showed that these wildlife ponds can support species assemblages at levels comparable to a farm dam in a Mallee woodland, demonstrating that wildlife ponds can be effective in providing a degree of ‘replacement’ habitat for birds on farms. Frogs were not recorded using wildlife ponds situated in Mallee woodlands and this was considered due to the wildlife ponds being placed at least 900 metres from a nearby water source potentially too far for many frog species to disperse in an arid environment. Given these findings, the position of ponds was adjusted for the ponds installed in Black Box woodlands. Wildlife ponds in Black Box woodlands were also successful in providing habitat for birds and functioned as an important source of water for water-dependant birds in summer. Frogs were recorded using the wildlife ponds situated in Black Box woodlands and this was most likely due to their close proximity (<200 metres) to a nearby water source, as well as being located in a wetland-associated vegetation type. The success of the wildlife ponds concept has been demonstrated both in their ability to function as habitat for water-dependant fauna and through widespread community acceptance and support. With the de-commissioning of the channel and dam system removing open water sources from the farming landscape, artificial wildlife ponds installed on farms across the region could provide not just a vital habitat resource supporting water-dependant fauna, but in many areas, the only source of water for wildlife within the Wimmera and southern Mallee regions.

- Description: The Android platform is the fastest growing smartphone operating system to date. Consequently, malware on Android OS has been increasing at an alarming rate. Similar to Windows-based malware, Android malware also have different families which are responsible for different malicious activities. In this thesis, we focused on one particular group of Android malware which is designed to target banks and financial institutions. These banking malware use different techniques to attack bank clients and banking servers. A coherent framework to analyse the behaviour of these malware needs to be developed, so the impact of theirs attacks could be minimised. This thesis investigates a systematic analysis to understand these malware’s behaviour and distribution method. From public and private sources, 37 samples of banking malware have been collected which represent eight major Android Banking malware families. In addition, we also analysed malware source code by reverse engineering all malware samples. As a result of analysis, a clear overview and better understanding of mobile banking malware on Android OS was established. The results indicated that Android banking malware is evolving in technique and will become more difficult to analyse in the future.

Exploring youth perceptions of school (dis)engagement and absence in Hepburn Shire

- Description: This thesis examines the educational experiences of some young people living in the Hepburn Shire, a Local Government Area (LGA) in the Central Highlands of Victoria. These young people were in various stages of disengaging from the mainstream education on offer in the shire. The research came about via consultation between the secondary school and Federation University in response to data from the Department of Education and Training (DET) showing that the Hepburn area had the lowest school attendance figures of the eleven LGA’s in the Grampians region. The school was interested in the reasons behind the lower figures and sought to gather some further information which might shed light on the experiences of young people who had difficulty in connecting, or staying connected to, school. It was hoped that the resultant findings would inform the approach taken by the schools in offering appropriate programs to support people to re-engage with school. Thus, the research question underpinning this research is: What are the key reasons that school attendance has been identified as being lower in the Hepburn Shire Local Government Area than in other parts of the Grampians region? A critical ethnographic study was undertaken comprised of participant observation, facilitated by the researcher being situated within the school, and a series of semi-structured interviews conducted with young people (of secondary school age), families, teachers, Principals, support staff including welfare providers and a selection of other professionals working with youth and their families in the Hepburn Shire. The study revealed a complexity within the Hepburn community, where a rich diversity of views about child-raising and education was present. Such views spanned philosophies about ‘unschooling’, the benefits of home-schooling, and a sense of permissiveness about not attending school each day. Further, there seemed to be a tendency within the school (both by teachers and other professionals working with youth) to talk about disengaged students and families of nonattending students in terms of deficit: there was something lacking with them, parenting skills, work ethic, behavioural or emotional regulation, that was viewed as contributing to the students’ poor attendance. Finally, the centrality of the teacher-student relationship to both student engagement and disengagement was evident in the conversations with young people and their families. Building respectful, reciprocal relationships with at least one key member of staff seems to be a major protective factor against disengagement. And further, seems to be a pre-requisite for those students who are entering the school for the first time, or who are re-entering after a significant absence.

Neurotrophic biomarker change after physical activity and mindfulness interventions
- Authors: England, Gina
- Date: 2017
- Type: Text , Thesis , Masters
- Full Text:
- Description: BACKGROUND AND AIM AND HYPOTHESIS: BDNF, FGF2 and NGF are neurotrophins associated with neuroplasticity, nervous system development and psychiatric disorder in the literature. BDNF in particular is suggested as a useful biomarker of mood disorder. Both mindfulness and physical activity are shown to improve mood, reduce stress and are widely used as part of a multi-component treatment approach, reducing distressing symptoms of mood and affect disorders. The utility of protein level as a biomarker has been controversial in the literature following issues concerning the assessment of peripheral levels as a proxy for central levels. The principal aim of this study was to investigate the gene expression of three neurotrophins BDNF, FGF2 and NGF as potential biomarkers of mood disorder, at an early stage of these disorders, which are now widely recognised as having pathogenesis related to dysregulation in the neuro-immuno-endocrine axis. In addition, the study will explore the effect of both physical activity and mindfulness on neurotrophin expression clarifying the associations between the success of these interventions seen in the literature and their effect on the change of neurotrophin expression. Current literature reports increased levels of BDNF protein both centrally and peripherally following mood disorder treatment and participation in both physical exercise and mindfulness activities. Based on similarity of structure and function amongst the three neurotrophins, this thesis will hypothesize an increase in BDNF and potentially FGF2 and NGF mRNA following participation in the two interventional modules designed to improve wellbeing in clinical and non-clinical communities. METHOD: In this independent measures design, 28 non-clinical volunteers were randomly allocated to an 8 week intervention, comprising digital health tracking modules and participation in an unstructured increase in Physical Activity or Mindfulness program, to assess the effect of these interventions on levels of mRNA expression. RTqPCR was used to compare relative mRNA abundance in peripheral blood at baseline and 8 week time interval. The control group were allocated to a waitlist for the period of the 8 week study, followed by access to the program of their choice. Change in emotional state was measured using the DASS. RESULT: BDNF expression is shown significantly increased (p 0.01, n=5) in the Physical Activity group, and significantly decreased in the Mindfulness group (p 0.01, n=11). FGF2 and waitlisted controls showed no significant change. In the case of NGF no expression was seen in human peripheral blood either before or after the intervention. DASS scores revealed a significant decrease in negative affect in the Mindfulness group p = 0.03. CONCLUSION: This study revealed a significant positive association between physical activity and BDNF mRNA, although no significant reduction in distressing mood symptoms was shown. This was potentially due to the small group size. Mindfulness was significantly associated with decreasing negative affect, despite an unexpected decrease in BDNF mRNA consistent with pathophysiology of depression, likely related to neuro-immunoendocrine axis disturbance as suggested in the published literature. It is suggested decreasing mRNA levels reflect lower numbers of immune activated leucocytes present in the blood following mood improvement, albeit not verified in the study. This study suggests even in a small non-clinical sample there may be potential benefits to well-being by increasing levels of physical activity or becoming mindful, and that BDNF has potential as a biomarker of emotional state.

- Description: Perseverance is a quality which individuals draw on to achieve their goals, despite any challenges they may face, and so is one of the keys to academic and life success. Perseverance is considered to be a positive attribute that can be learned. In this study, how tertiary students understand perseverance, how they acquired it and its role in their lives and learning are explored. The research sample for the study consists of nine pre-service teachers from Initial Teacher Education (ITE) in regional Victoria, Australia. The researcher uses semi-structured interviews, and draws on educational and salutogenic theory and a qualitative methodology. The data has been analysed within the Ecological framework based on the work of McLeroy and colleagues (1988). In the introductory chapter the aims of the study are outlined, perseverance is defined and its significance as a character strength/ attribute is considered. The second chapter, the literature review, explores the extent to which perseverance, along with associated character strengths, has been identified as a significant factor that influences educational achievement and the ability to meet life’s challenges. The third chapter provides justification for applying a qualitative phenomenological methodology, with particular attention to describing both the salutogenic theoretical perspective and the Ecological Model (EM). The fourth chapter, the data analysis, identifies themes within the data and these are discussed with reference to the relationships between the EM layers. The fifth chapter offers the discussion, implications and conclusion of the study. The research findings indicate that all the participants defined perseverance as an attribute or character strength which they called on to overcome challenges and obstacles as they pursued their goals. They associated it with such qualities as persistence, motivation, commitment, focus, goal-setting and strength, amongst others. They recognized perseverance as integral to their academic success as well as to their ability to manage crises and challenges in their lives. They identified multiple contributors to their acquisition of perseverance, including family members, friends and some teachers. Many of the participants identified instances when they made a conscious decision to persevere, and viewed the experience as definitive in their growth as mature people. However, few of the participants considered the schools they attended to have played a significant role in developing their understanding of perseverance or of helping them acquire it, though they were appreciative of those teachers who gave them general support and encouragement. They recognized the importance of schools and teachers explicitly teaching perseverance and supporting its development through positive critique and feedback, and of students experiencing multiple opportunities for practising perseverance at the individual, family, school and policy levels. In educational practice, these conclusions suggest that further research into how best to implement these approaches across all schools would be invaluable.

The assumed divide : Examining gender, feminism and relationships through visual art
- Authors: Hollis, Sylvia
- Date: 2017
- Type: Text , Thesis , Masters
- Full Text: false
- Description: The Assumed Divide is a visual arts based, practice-led research project which explores expectations of gender within the context of interpersonal relationships, structured through feminist theory. I created a collection of small, figurative sculptures inspired by experiences of animosity and misunderstanding, to locate areas of gendered interpersonal ambivalence. This thesis proposes that feminism might enhance gender relations by deconstructing harmful stereotypes and by encouraging empathy and respect for diversity. Issues such as reproductive choice, intergenerational debate, and uncertainty in aims are discussed as apparent impediments to the unity of feminism, against a patriarchal tradition that grants men categorical universality. I argue that by dismantling the perception of male unification and by elucidating the multitudinous similarities and variances of human experience, feminism makes advances in eliminating sexism. I also examine how binary gender division, with an assumption of distinct difference between male and female, generates conflict and power dynamics advantageous to men, diminishing the quality of heterosexual and social relationships. The observation that overlapping gender traits blur boundaries of male and female, and that rigid categorisations are not indisputably representative of all people, may offer more points of connection to bridge the divide of gender. Each artwork in The Assumed Divide reflects on gendered experience, with sculpted depictions of disintegrated flesh acting as visual manifestations of the psyches and social conditions of the figures. Working realistically on a small scale, and integrating found silver trays as motifs of domesticity and relationships, my intent is to directly stimulate contemplation of the themes in context to viewers’ lives, recognising that the audience is free to find their own meaning in the works. Discussion of these pieces, alongside works by other artists who broach topics of feminism, gender, and relationships, exemplifies the capacity for art to infuse theory with personal insight, inspired and derived from the lives of both artist and viewer.

The lost opportunity of Melbourne's outer circle railway
- Authors: McKenna, Trevor
- Date: 2017
- Type: Text , Thesis , Masters
- Full Text:
- Description: This thesis examines a little known railway line in Melbourne, the Outer Circle Railway (OCR) running from Oakleigh in the south-east to Fairfield in the north. There is great significance to its east-north trajectory, because I will argue, it was conceptualised as a major part of the Melbourne system, for the future; a future that ostensibly lasted only two years, before the economic depression of the 1890s caused it to close in stages. It further brought in many more strands to the Melbourne transport nexus, as it circumnavigated the inner suburbs. I ask the key question ‘was the Outer Circle Railway a lost opportunity’? Though considered one of the great public transport cities of the world, Melbourne with its extensive rail and tramway networks succumbed to the winds of change, embodied by the Fordist principles of private car ownership, freeway building and traffic systems. The public transport budget was cut in the second half of the twentieth century – leaving Greater Melbourne in constant gridlock, in the twenty-first century. I use documentary analysis to examine primary and secondary documents, to comprehend whether the almost immediate denigration of the OCR, by newspapers and most historians, was warranted. Certainly I find many contemporaneous champions of the OCR, which was built to the highest British standard, as was the entire Victorian Railways system. My key finding is that the OCR rail line could be utilised in the modern era. The OCR route is pointed squarely towards Tullamarine airport, and could be used as a basis for the long-sought rail link to the airport. The decision of the Andrews Labor Government in 2014 to abandon the contentious East-West road tunnel in favour of rail projects reflects the need for a growing city to privilege public transport, as it did in the nineteenth century.

"Beyond home and sex?" : Gender and sexuality in Elizabeth Moon's
- Authors: O'Sullivan, Jennifer
- Date: 2018
- Type: Text , Thesis , Masters
- Full Text:
- Description: Historically, fantasy fiction has tended to present sexuality and gender in a conservative light. Contemporary authors in this genre have the opportunity to imagine worlds in which they can critique these norms and offer new and subversive alternatives. Elizabeth Moon’s work has been seen by some readers and critics (Mains, et al, Bach) to challenge conservative gender roles, and while in some areas this is evident, a critical reading of her Paksworld series through a feminist lens reveals that her work is still largely restricted by normative notions of gender and heteronormative contexts and ideals. In this thesis I argue that while Moon’s female characters are allowed a certain amount of autonomy, they are still often repressed by those around them, silenced, or subject to male dominance and/or sexual violence. Those women in the novels who achieve a position of social, political or spiritual power are forced to make choices between roles: for example, between being a warrior and a mother, and are not allowed to ‘have it all’. Moon does subvert some familiar feminine tropes – her fantasy princesses for example avoid being married against their will, and her female warriors are more complex than simply being ‘sheroes’. Utilising masculinities and disability theory, I also analyse Moon’s treatment of men and masculinity. While Moon presents several familiar male fantasy tropes, she also portrays some surprisingly subversive men. These men are forced to reimagine and reinterpret their own masculine identities by having to confront ageing, disability, mutilation and loss of personal power while negotiating traditionally masculine homo-social environments. Finally, I argue that Moon’s presentation of sexuality in the Paksworld series is problematic and conservative in that very few of her characters are having pleasurable, consensual sex, especially not outside traditional marriage structures. Furthermore, the Paksworld series is largely heteronormative, with same-sex desire identified predominantly with a character who is presented as an antagonist to Paks. Paks herself is asexual, and I argue that Moon uses this as a way to avoid dealing with the issue of female sexual desire rather than an opportunity to explore asexuality as a valid sexual preference or identity. Overall, I argue that despite some subversive elements, Moon’s characters are still largely restricted by conservative expectations of genre, culture, gender and sexuality.

A conceptual framework for a theory of liquidity
- Authors: Culham, James
- Date: 2018
- Type: Text , Thesis , Masters , PhD
- Full Text:
- Description: This study contributes to the understanding of liquidity in two ways. First, it considers the multifaceted nature of liquidity and its relationship with money. Second, it constructs a conceptual framework for a theory of liquidity. The first contribution is achieved by clarifying and categorising the various forms of liquidity to identify those overlooked by the existing literature. The second contribution consists of a realist critique of the literature on liquidity and money to highlight the strengths and weaknesses of each theoretical approach. The study reflects on the attempts to analyse liquidity using moneyless models of perfect barter with the assumption that every commodity exhibits perfect saleability; an assumption that removes any need for a medium of exchange and, moreover, crowds out all other forms of liquidity. It is concluded that, because liquidity is a social and monetary phenomenon, it cannot be analysed with models populated by a representative agent consuming a single commodity. Furthermore, this conclusion is not altered by the introduction of ‘financial frictions’, which are fundamentally at odds with the nature of money. Instead, the clarification of the nature of liquidity forms the basis for an interpretation of Keynes’s theory of liquidity preference that emphasises its reliance on liquidity in general, not money in particular. The study introduces the terms redemption liquidity and exchange liquidity to explain the trade-off that underpins the theory of liquidity preference. Properly interpreted, the theory of liquidity preference can then address many of the deficiencies prevalent in the dominant theories of the rate of interest. The study therefore has implications for monetary policy and asset pricing.

An experimental investigation into the drainage properties of coarse Loy Yang pond ash
- Authors: Stipcevich, Jack
- Date: 2018
- Type: Text , Thesis , Masters
- Full Text:
- Description: The Latrobe Valley mines, Victoria, Australia, are facing some major challenges as they approach the end of their mining life. Most of these challenges surround current rehabilitation practice and the ability to create safe and stable landforms for future land uses well after the mines have closed. As there has been no developed alternative use for the brown coal at this stage, stopping power generation leads to the cessation of mining. AGL Loy Yang is undertaking rehabilitation cover trials on exposed coal batters to investigate optimal cover materials that will enable safe and stable batters well beyond mine closure. A series of rehabilitation trials using coarse coal ash have been constructed by AGL to assess the performance of coarse coal ash as a ‘subsurface drainage layer’. One of the trials includes the use of a 1 metre coarse coal ash layer placed below a 1 metre thick clay cover and above a coal surface shaped to approximately 18 degrees (1V:3H). Without a drainage layer, water may percolate through the clay cover or seep through the intact brown coal, resulting in a build of pore water pressure at the coal – clay interface and increasing the potential for slope failure. The aim of this research work was to assess the spatial distribution of ash properties known to affect drainage behaviour at the field scale; to test and calibrate field-monitoring equipment that can be used to assess drainage behaviour at the field-scale; to provide recommendations for further research on the use of coal ash drainage layer; and to provide a benchmark for future testing and monitoring. Through an experimental investigation, it was shown that there no significant variation exists in the coarse fraction of Loy Yang pond ash’s physical and chemical properties. Monitoring equipment used to determine the field drainage performance of the ash included a T8 Tensiometer and EnviroPro (multi-capacitance sensor) that were calibrated and tested in the laboratory. It was determined that monitoring devices used in this study were suitable for measuring the ash’s hydraulic behaviour only once calibrations had been performed. As a result the tested field equipment were included in the design of a future monitoring program.

From gold field to municipality : The establishment of Ballarat West 1855-1857
- Authors: Cartledge, Graeme
- Date: 2018
- Type: Text , Thesis , Masters
- Full Text:
- Description: This thesis examines the establishment of the Ballarat West Municipality in the years of 1855 – 1857 and the factors that contributed to the introduction of local self-government in the immediate aftermath of the Eureka Stockade. Underlying the study is the changing administrative requirements necessitated by the transition from a temporary gold field to a permanent city. A central theme explored in relation to this development is that it was a consequence of the emerging culture of modernity of that era precipitating radical political changes in local government that began with the 1835 British Municipal Corporations Act. This theme is expanded to highlight the reform of local government in the Victorian era in response to urbanization and the need for modern and rationalised methods of managing the new towns and growing cities. The difficulty in making and sustaining such progressive changes in Britain is contrasted with the eager adoption of the concept of progress and the new Victorian Municipal Corporations Act of 1854 on the Ballarat goldfields. The question as to why the Municipality was established is answered by exploring the connection between the failure of the Goldfields Commission at the end of 1854 and the belief held by many, that taxes should be accompanied with political representation and should be spent where they were collected. This study exposes the remarkable story of how the first elected councillors, starting from scratch, quickly established administrative systems and brought order to a community emerging out of turmoil. The process of how the municipality was established is uncovered by an extensive survey of the council minutes, the media, council correspondence and public records.

Measuring depression in deaf adults : Adaptation and validation of the Patient Health Questionnaire 9 (PHQ-9) for Auslan users
- Authors: Lake, Shane
- Date: 2018
- Type: Text , Thesis , Masters
- Full Text:
- Description: There is limited research into the prevalence of depression in the deaf population. Results are inconsistent and research has been hampered by the use of measures not specifically designed for individuals who are deaf. Deaf adults, who use Australian sign language (Auslan) to communicate, may not have the spoken and written language skills in English that are required to understand standard psychological measures. The aim of this research was to adapt and validate a measure of depression, the 9 item Patient Health Questionnaire (PHQ-9), for deaf Auslan users. Following established guidelines, an Auslan version of the PHQ-9, that was conceptually equivalent to the original measure, was produced. A community sample of 34 deaf adults, who use Auslan to communicate, and 278 hearing adults, were recruited from the Australian population. Deaf participants completed an Auslan online survey that included the Auslan version of the PHQ-9 and a previously adapted measure, an Auslan version of the Depression Anxiety Stress Scales-21 (DASS-21-Auslan). Hearing participants completed a written English version of the online survey. The Auslan version of the PHQ-9 demonstrated good internal reliability. Concurrent validity was established using the DASS-21-Auslan, with significant correlations found between the two measures. Principal components analysis identified a single factor structure for the Auslan PHQ-9. Differential item functioning was examined using a parametric technique (ordinal logistic regression) and a non-parametric kernel smoothing technique (TestGraf). No evidence of item bias was found. This research has provided promising results for an Auslan version of the PHQ-9 as a culturally appropriate measure for Auslan users. The Auslan PHQ-9 has the potential to provide mental health practitioners and researchers with a more accurate method of assessing and monitoring depression and depressive symptoms in deaf adults who are Auslan users.

Hearing participants completed a written English version of the online survey. The Auslan version of the PHQ-9 demonstrated good internal reliability. Concurrent validity was established using the DASS-21-Auslan, with significant correlations found between the two measures. Principal components analysis identified a single factor structure for the Auslan PHQ-9. Differential item functioning was examined using a parametric technique (ordinal logistic regression) and a non-parametric kernel smoothing technique (TestGraf). No evidence of item bias was found. This research has provided promising results for an Auslan version of the PHQ-9 as a culturally appropriate measure for Auslan users. The Auslan PHQ-9 has the potential to provide mental health practitioners and researchers with a more accurate method of assessing and monitoring depression and depressive symptoms in deaf adults who are Auslan users.

Pandemic Influenza at Oodnadatta, 1919 : Aspects of treatment and care in a multiracial community
- Authors: Bullen, Heatheranne
- Date: 2018
- Type: Text , Thesis , Masters

- Description: On 24 January 1919, a thirty-two-year-old nurse from Sydney, Jean Williamson, disembarked at the railway station at Oodnadatta in the far north of South Australia to commence her new role as sister in charge of the Australian Inland Mission (AIM) hostel. On 18 April that year, Williamson greeted thirty-four-year-old minister from Melbourne, Coledge Harland, who had arrived by train to take up a three-year post as padre for the AIM’s central Australian parish. Just over a month later, an influenza pandemic that had already killed untold numbers of people worldwide reached the isolated township. Drawing on primary documents, including an extensive collection of previously unseen photographs, letter and diaries from Harland and Williamson, this thesis examines the management and care of pandemic influenza at Oodnadatta from May to late July 1919. Intercultural aspects of the management and care of European, Afghan, Chinese and Aboriginal patients are examined in the context of the health and lifestyle of local residents, nursing practices, medicines, foods, accommodation and the contribution of individuals, groups and their roles. This intimate microhistory sheds light on a relatively unknown, yet important group of people in Australia’s frontier history: the missioners and others who cared for seriously ill Aboriginal and non-Aboriginal patients at Oodnadatta, provided culturally sensitive care that afforded respect, dignity and compassion to all. At the time, the gravity of the world wide situation and the sheer need to provide care saw individual efforts go unnoticed; however, in hindsight, it is possible to see and appreciate the significance of what they achieved under the most difficult of circumstances.

Susceptibility of rehabilitated mine batter surface to mass movement
- Authors: Allen, Tristan
- Date: 2018
- Type: Text , Thesis , Masters
- Full Text:
- Description: The goal of the research is to quantify coal properties that may affect the processes and controls governing rehabilitated brown coal mine surface mass movements. The research investigates weathering of coal and assesses the difference in strength characteristics between fresh and weathered coal. In addition to quantifying the mechanical properties of coal surfaces in a rehabilitated slope, permeability changes due to weathering of coal are also investigated. Changes in coal strength influence sliding resistance. Changes in coal permeability impact pore pressures above the coal surface, which may also affect sliding resistance on the coal – cover interface. To assess these issues, direct and residual shear tests were used to investigate the changes in shear strength due to weathering at low normal stresses applicable to shallow cover materials. Testing was undertaken with abrasive surfaces to simulate sliding on the contact coal surface beneath cover materials assuming that the cover material is stronger than the coal. The roughness of the abrasive surface proved to be unimportant for large strain shear strength. The shear strength for coal with different weathering and normal effective stresses was examined. Coal cohesion was found to be low, but some rebinding of coal would occur with time. A coal residual friction angle of 39.1 and 37.0 degrees was found for the unsaturated and saturated tested coal respectively. Permeability tests using oxygenated water were undertaken to investigate changes to brown coal permeability as a result of weathering. Even with low levels of oxidation achievable with the permeability test apparatus, coal permeability dropped over time. While the magnitude of the reduction was not large for low oxidation magnitudes, the impact on permeability was demonstrated. A weathering index was developed as part of the study to provide a quantitative basis for assessing the weathered state of coal samples. The index employed changes to Fourier Transform Infrared Spectroscopy (FTIR) spectra to define the state of weathering. To assess the rate and magnitude of weathering of coal through oxidation an autoclave was used to artificially weather brown coal. Fourier Transform Infrared Spectroscopy and Gas Chromatography used to analyse the results. As for the permeability testing the autoclave experiments could not be run for sufficient time to progress to complete weathering by oxidation. Nevertheless the principles of the test and the equipment specifications were developed so that they could be used in future to complete the determination of weathering rates. The research has demonstrated the importance of understanding coal weathering at the upper boundary of a rehabilitated coal surface to the potential for cover mass movements due to sliding at the coal cover interface.

The collaborative designer : An investigation into the lived experience of co-design practice
- Authors: Smith, Chrissie
- Date: 2018
- Type: Text , Thesis , Masters
- Full Text:
- Description: This enquiry is motivated by a growing recognition of citizen participation by design disciplines and other disciplines outside of design (such as social science, science and business) in solving complex problems across society. Co-design is the approach that this research focuses on in particular. Codesign is a new field of collaborative practice that has emerged from the Scandinavian tradition of Participatory Design. Integral to the philosophy of both these practices is the decentralisation of the individual expert designer and the empowering of the end user as an active participant. Despite many studies that have provided useful frameworks and insights into the practice of co-design, conceptualisations and discussions around implications for participation and design deployment rarely include the voice of the co-design practitioner. This study uses a descriptive phenomenological approach to explore the experience of practitioners, some trained in design and some not, facilitating co-design practice. Aligned with this approach, detailed interviews were conducted with six practitioners from Australia and New Zealand to understand what is unique or contingent to them personally, situated within their practices. Through a process of detailed and analytic exploration of these six individual descriptions of the phenomenon under investigation, the core constituents of the experience of co-design practice were distinguished for each participant. From these constituents, general structures representing the essences, or invariants common to all experiences under investigation were identified. Based on the careful analysis of the narrative descriptions from the interviewed practitioners, the core aspects of their practice in collaboration with end-user groups and other stakeholders are described. A visual framework is proposed that capture the complexity of their lived experiences of co-design practice.

The contribution of poker machines to reduced community wellbeing : A pre and post study
- Authors: Bell, Diana
- Date: 2018
- Type: Text , Thesis , Masters
- Full Text:
- Description: This thesis reports on a study of the impacts of poker machines on community wellbeing, using a pre and post survey method. The study used a variety of indicators to test community wellbeing and gambling attitudes and behaviours before and after a hotel venue with 40 poker machines opened in a new suburb in the designated growth area of Melbourne’s northern fringe. There was a higher proportion of respondents who met the criteria for ‘problem gambling’ after the poker machines were installed, compared to before, particularly when considered as a proportion of people who gambled on poker machines (5.3% compared to 3.6%). A proportion of respondents reported reduced levels of personal happiness, contentment and wellbeing as a result of the introduction of poker machines (16.5%, 12.3% and 16.1% respectively) and 41.5% reported there had been a detrimental impact on the community, in terms of social character. Mean scores on sense of community indexes and social cohesion showed a small decline in the post sample on every measure. Overall, the community reported reduced wellbeing on all measures after the introduction of poker machines. The significance of this study is that measures of community wellbeing and attitudes towards poker machines were measured before their introduction so that this baseline data could be compared with reported wellbeing 18 months after their installation within the suburban area. The substantial proportion of respondents who reported detrimental impact on social character, along with many negatively expressed opinions of poker machines, and a higher rate of problem gambling provide support for the notion that the introduction of poker machines at least contributed to the reduction in community wellbeing. This research provides some suggestions for the use of indicators for measuring the impact of poker machines on community wellbeing.
