- Description: This thesis is a political history of the emergence and evolution of selected radical, left, student and workers movements in Victoria between 1965 and 1975. It examines the development of radical alliances, demonstrations and public actions using documentary materials and oral accounts provided during interviews. It argues that the radical left movement in Victoria began within the Monash University Labor Club, which subsequently generated radical groups outside the university. During this timeframe, both military conscription for the Vietnam War and the war itself became focal points for oppositional political mobilisation in Victoria. In 1967, the Monash Labor Club’s disruptive campaign against university authority was sufficiently popular for the club to turn its attention to disrupting the war effort. Soon, its locus of operations shifted into the general anti-war movement and the Labor Club established new, non-student, and avowedly communist and revolutionary organisations. Roughly termed the “Maoists,” by 1970 these organisations coalesced into the Worker Student Alliance (WSA), which grew rapidly to become a “left-wing” body that challenged the leadership of the established “left” organisations. The cessation of Australia’s involvement in the Vietnam War removed a major cause for radical action and, despite the generation of some important campaigns to replace it, the WSA dissolved itself in 1974.

Intelligent sewer blockage detection system using Internet of Things
- Authors: Buurman, Benjamin
- Date: 2019
- Type: Text , Thesis , Masters
- Full Text:
- Description: Despite being a common issue in both developed and developing countries, wastewater blockages have severe potential consequences. Blockages can be located at sewer mains or individual properties and can also be classified as partial or full. Full blockages completely obstruct a wastewater asset, and partial blockages will often develop into full blockages if left unattended. Currently, blockages are managed by routine manual inspections to wastewater assets on a round-robin schedule. This is highly inefficient and costly, as blockages that form between these inspections and progress to effluent breaches will go undetected. In this thesis we present an Internet of Things (IoT) solution capable of simultaneously monitoring an entire wastewater infrastructure for blockages while still remaining inexpensive, reliable, and practical. Wireless motes use float switch sensors to detect blockages and transmit this to a central system using either LoRa or Wi-Fi communications. Making both LoRa and Wi-Fi available ensures the system can be adapted in any situation across a variety of geographic and economic restrictions. The central system determines whether a surcharge is caused by a blockage or simply the result of regular activity not requiring intervention. Detection of false positives is critical, as deployment of field technicians is an expensive process that moves resources from other skilled work. If a surcharge is determined to be caused by a blockage, the central system will classify it as full or partial before estimating the property or length of main between properties it is located at. Following this, relevant parties will be notified so field technicians can be deployed to resolve the blockage. We performed both practical laboratory testing and simulation modelling on our proposed system, and confirmed it is indeed capable of detecting, classifying, and locating blockages across a wide urban area. Our choice of hardware, software and network equipment ensures that the proposed IoT-based solution is inexpensive, workable, and easily deployable.

- Description: One of the difficulties in writing a regional history such as this thesis was the sensitivity surrounding the appropriate choice of terminology and spelling conventions. Conflicts have arisen between conforming to the standardisations of the History Discipline and a desire to accommodate the wishes of the indigenous communities in the geographical area of this study. The absence of trained linguists in the white community during the initial colonisation period has resulted in a considerable divergence of opinion over the nomenclature and spelling derivatives surrounding the indigenous people living in what is no w known as the Geelong-Ballarat region. The first white chroniclers referred to the Wathawurrung by a myriad of different names (over 100 different names were recorded by Clark for the people in this study area) including: Watowrong, Wartowrong, Wot o wrong, Watourong, Wodowrow . Throughout the text ofthis work 1 have applied the term Wathawurrung' to all indigenous groups in primary documents that involve the known language area of the Wathawurrung. Where there is some doubt as to which tribe is being referred to 1 have included other language groups that the writer ma y have also been referring to. " From Preface"

I hope that I have got some art

- Description: In this thesis I have researched what I believe is the powerful, catalytic effect of poetry on the creative work of some artists. I have chosen three, Australian painters; Sidney Nolan, James Gleeson and Brett Whiteley. I have looked carefully at how the works of various poets have influenced and inspired these artists. I have put forward the idea that this engagement with the poetic realm has greatly enhanced the artist’s creative form-making. Indeed these artists have acknowledged their strong links with the world of poetry. I have touched very briefly on the ideas of some renowned philosophers who stress society’s need for fine works of art. In my opinion great works of art can come from this linking of painting with poetry and therefore, this nexus is to be encouraged. I have in my own painterly works looked to the poets for inspiration. In The Wimmera Series of landscape works, I read Brian Edwards’ and Homer Reith’s poetry, and found in their imagery a rich source of creative ideas. I continued to read the works of the poets and found that the poetry of Ezra Pound, Dante Alighieri, Judith Wright and the works of many others, were an inspirational and catalytic force. I have also discovered on this artistic journey that the very writing of poetry, my own attempts in this field, seemed to bring to my painting, a sharper, a more analytical and critical focus. Renowned art critics and art historians have criticised contemporary art for its lack of the poetic, and its boring shallowness. I would urge artists to engage with the poetic realm, and this interplay between painting and poetry, may produce fine works of lasting greatness.

Under the influence : identifying determinants of young adults' involvement in alcohol-influenced aquatic activity to improve drowning prevention efforts
- Authors: Calverley, Hannah
- Date: 2020
- Type: Text , Thesis , PhD
- Full Text:
- Description: BACKGROUND: Young adults are an at-risk group for experiencing an alcohol-related drowning incident. Investigations and drowning prevention efforts have aimed to address young adults’ prevalence in alcohol-related drownings and contribute to understanding their level of risk. Some explanations have concluded young adults’ need for autonomy and independence coincides with their exposure to alcohol and social norm pressures. However, gaps in knowledge remain, specifically young adults’: behaviours, knowledge and attitudes towards alcohol-influenced aquatic activity and the associated risks; and, their awareness and perceptions of alcohol-themed drowning prevention campaigns. METHODS: This PhD, completed with publications, aimed to address these gaps through four interlinked projects: (i) a systematic review of alcohol education programs to determine evidence-based quality criteria necessary for inclusion in programs to successfully change young adults’ alcohol-related behaviours, knowledge and attitudes; (ii) a program audit of alcohol-themed drowning prevention campaigns to establish current prevention efforts in high-income countries and areas for improvement; (iii) a survey among young adults from Australia and the United Kingdom to establish their knowledge, attitudes and predictors of intentions and involvement in alcohol-influenced aquatic activities; and, (iv) interviews to deepen understanding of young adults’ knowledge, attitudes and behaviours relating to alcohol-influenced aquatic activity, their awareness of alcohol-themed drowning prevention campaigns and their suggestions for improvement. Six publications resulted from this research. RESULTS: Friends influenced frequency of young adults’ involvement in alcohol-influenced aquatic activity, but involvement was dependent on the characteristics of the peer group, self-confidence and risk disassociation. Attitudes were neutral towards alcohol-influenced aquatic activity, but when participants perceived personal control over the risks it was deemed more acceptable. Alcohol-related safety strategies from other contexts (e.g., driving) were applied to aquatic settings, but specific water safety knowledge/education was low. Stronger swimmers, Australian young adults and those who had received alcohol-specific water safety education displayed more knowledge of alcohol and its effects in aquatic contexts. Participants lacked awareness of alcohol-themed drowning prevention campaigns, and used campaign logos and names to interpret key messages. Little information was available on the alcohol-themed drowning prevention campaigns identified in the program audit and only two had evidence of evaluation, limiting progress of future prevention efforts. Ten quality criteria identified from evidence-based literature were considered to be necessary for inclusion in alcohol education programs. Programs included in the systematic review which incorporated these criteria were more likely to report success in influencing behaviour changes among the participants. CONCLUSIONS: To decrease the incidence of alcohol-related drowning among young adults, the findings of the projects included within this thesis result in the following recommendations. For enhanced likelihood of successful outcomes, alcohol-themed drowning prevention campaigns should align campaign design, implementation and evaluation with best-practice literature. The identified influencers on young adults’ involvement in alcohol-influenced aquatic activity, such as their peers, should be incorporated into prevention efforts and appropriate information provided to encourage informed decision making. Alcohol education programs (e.g., drink driving education) should include information about alcohol use in aquatic settings to clarify the risks associated with transferring safety strategies between drinking contexts, and appropriate information should be provided about alcohol consumption in aquatic settings.

[Dis]Abled justice: Why reports of sexual assault made by adults with cognitive impairment fail to proceed through the justice system
- Authors: Camilleri, Marg
- Date: 2010
- Type: Text , Thesis , PhD
- Full Text:
- Description: Doctor of Philosophy
- Description: This study considers why, despite increased prevalence of sexual assault perpetrated against adults with cognitive impairment, reports of sexual assault made by adults in this cohort to the police seldom progress beyond the investigation stage. The study is informed by a triangulation of theoretical perspectives consisting of radical feminist theory, symbolic interactionism and the social model of disability. A combined qualitative and quantitative methodological approach is underpinned by the social constructionist epistemology. Data was gathered through 13 focus group discussions conducted with Victoria Police members, including members of the Sex Offences and Child Abuse Unit, Criminal Investigation Unit and Sex Crimes Squad, as well as with staff from the Office of Public Prosecutions and advocates consisting of disability and victim support workers. The other main sources of data were 76 police case file narratives and a case study involving an adult victim whose report of sexual assault was successfully prosecuted. Qualitative data from focus group interviews and file narratives were subjected to thematic analysis and critical discourse analysis. Basic frequencies and correlations of the case file data were analysed using SPSS and the case study was analysed utilising Yin’s (2003) explanatory case study framework. The research indicates that there are seven points in the course of police investigations at which decisions are made about sexual assault reports. Discretion is applied by police at all stages of decision making. Decisions are informed by an influence cycle consisting of social forces, the justice system, the police organisation, and the culture of the police unit. Police decisions are therefore subject to a range of influences, which perpetuate negative patriarchal and ableist stereotypes and disabling generalised assumptions about adults with cognitive impairment. The primary assumption is they are not credible. The result is that opportunities for people with cognitive impairment to access justice are extinguished prematurely.

Learning a trade in New Zealand : On and off the job learning in engineering trades
- Authors: Cannan, James
- Date: 2017
- Type: Text , Thesis , PhD
- Full Text:
- Description: The engineering trades selected for this study were specifically in the automotive and refrigeration/air-conditioning/electrical disciplines, as they are typical of the engineering discipline trade groups studying at institutes of technology and workplaces as apprentices. This research focused on two trade occupations within the engineering industry and investigated differences between pre-apprentice and apprentice experiences in skills and knowledge acquisition and assessment whilst learning on and off the job; that is, studying vocational education at institutes of technology and engaging in practical activities at the workplace. New Zealand has faced dramatic changes in tertiary education over the past 20 years, particularly in the vocational education and training (VET) sector. As a result of these changes there has been a substantial increase in participation in education and training. There is now a far wider range of courses to cater for the needs of learners in the vocational sector as the New Zealand population grows, along with the engineering trade opportunities that are currently available in the workplace. A qualitative research approach was used including interviews, focus groups and questionnaires. The project consisted of case studies based around cohorts of apprentices and pre-apprentices. Lecturers and employers were also included. The findings of the study will inform discussions on the ways in which learning prior to and in the workplace might be more effectively facilitated and managed in the future. It also raises questions about the effectiveness and quality of current training and assessment of engineering trade programs of study within New Zealand, as well as issues in apprenticeships and attrition within specific trades.

The construct validity of the Attention-Deficit/Hyperactivity Disorder and Oppositional Defiant Disorder symptoms : A multitrait-multisource approach based on father and mother ratings
- Authors: Carroll, Steve
- Date: 2005
- Type: Text , Thesis , PhD
- Full Text:
- Description: There has been considerable debate over the construct validity of the Attention-Deficit / Hyperactivity Disorder (AD/HD) and Oppositional Defiant Disorder (ODD) symptoms in past research due to measurement error (e.g., source effects) associated with parent and teacher ratings of childhood behaviour. Recent multitrait-multisource (MT-MS) studies have attempted to account for measurement error by using multiple sources involving parents and teachers. These studies have identified low trait variance in the AD/HD and ODD dimensions, thereby raising questions about the validity of the AD/HD - inattention (IN), AD/HD - hyperactivity/impulsivity (H/I), and ODD constructs. However, as these studies examine ratings from different settings (i.e., home and school) it can be argued that the low trait variance in the AD/HD constructs may reflect cross-situational differences. The current research used confirmatory factor analysis (CFA) procedures to examine the internal and external validity of AD/HD and ODD symptoms based on ratings (i.e., mother and father) from individuals in the same setting...

Bitcoin : users’ characteristics, motivations and investment behaviours
- Authors: Carter, Corey
- Date: 2019
- Type: Text , Thesis , PhD
- Full Text:
- Description: In less than a decade, the cryptocurrency known as Bitcoin has gone from a fringe phenomenon to a topic of increasing interest to academia and mainstream investors. However, despite the growing body of research seeking to understand Bitcoin, the pseudonymous, decentralised, and globally-diffused nature of its user base means that the individuals who use it remain poorly understood. In particular, the motivations, risk-appreciation, and investment behaviours of early adopters and innovators are subject to supposition in the absence of data derived from the user base. This thesis seeks to address this gap in knowledge by employing a multi-stage, mixed methodology approach and a theoretical framework to understand the Bitcoin user base. Utilising semantic analysis, a survey of online cryptocurrency communities, and econometric time-series analysis, this thesis addresses the extent and nature of Bitcoin in hedging; how individual users perceive their own motivations, uses, and risks that have driven their behaviour; and the nature of the relationship between the prices of cryptocurrency and indices of confidence. Analysis of the data determined that the use of Bitcoin as an instrument of hedging is limited, and influenced by political and institutional factors. Likewise, its motivations, uses, and risks are reflective of the users’ political ideology, with the community and marketplace becoming more sophisticated as they evolve over time. Additionally, despite several case studies demonstrating risk-averse adoption of Bitcoin, there is no relationship between its prices and confidence.

- 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.

- Description: Cyperus aromaticus (Ridley) Mattf. & Kükenth, commonly known as Navua sedge is an invasive C4 perennial sedge species of the Cyperaceae family found predominantly in tropical environments. A native of tropical Africa, it has spread widely and become problematic in many southwest Pacific islands and in tropical north Queensland, Australia. It is a principal weed infesting pastures, sugarcane, banana and root crops, which causes significant damage across a range of industries including dairy, beef, sugarcane and banana in the highly fertile and productive areas of Queensland. The primary objective of this thesis was to contribute to a significant weed management problem at a stage where intervention is cost effective, efficient and environmentally sensitive. At the centre of this work, was a contribution to fundamental knowledge regarding the ecology of the species. The first objective was to examine the global literature on rhizomatous weeds and C. aromaticus in particular to identify the research problems and knowledge gaps. As C. aromaticus has dual mode of reproduction, via seeds and rhizomes, both these aspects were taken into consideration in the experimental chapters. The project critically addressed the issues related to (i) understanding the fundamental ecological aspects of reproduction via seeds in C. aromaticus, (ii) the regeneration of C. aromaticus from its rhizomes, and (iii) control of C. aromaticus using herbicides. A stepwise approach, involving multiple objectives was used to meet the primary objective of this project. Three experiments were conducted to understand the fundamental ecological aspects of reproduction via seeds. (i) A study was conducted to understand the soil seed bank dynamics of pastures invaded by C. aromaticus. It was found that C. aromaticus is the dominant species in the soil seed bank of pastures invaded by C. aromaticus and can contribute between 62% and 95% of the total seed bank. In this respect, the abundance of C. aromaticus seed in the soil seed bank is positively correlated with the aboveground biomass of C. aromaticus and 83% of the total C. aromaticus seeds was found in the top 0-5 cm layer of soil. (ii) The lifespan of C. aromaticus seeds was estimated by artificial ageing technique in the laboratory whereby the results indicate that long-term management is required to control the recruitment from the soil seed bank even in the absence of additional seed deposition. (iii) Seed germination ecology was investigated to understand the effect of various environmental factors on the germination of C. aromaticus seeds. It was found that light is absolutely required for C. aromaticus seed germination, and there was no germination of seeds above 150 mM NaCl concentration and -0.8 Mpa osmotic potential, or from seeds buried greater than 2 cm below the soil surface. Focussing on the regeneration from C. aromaticus rhizomes, an experiment was conducted to investigate the effect of rhizome size and burial depth on the emergence from rhizomes in different soil types. A positive correlation was found between the total emergence of tillers and rhizome fragment size of C. aromaticus, but a negative correlation was found between the total emergence of tillers and burial depth of rhizomes. Importantly, it was also found that rhizomes when reduced to 10 cm or smaller fragments and buried 15 cm or deeper will prevent emergence. A further two glasshouse experiments were conducted to explore chemical options to control both the aboveground biomass and the belowground rhizomes. (i) The herbicide sensitivity of various rates of halosulfuron-methyl was evaluated at different growth stages using plants with and without established rhizomes. Mortality of 27.5%, 0% and 5% was recorded when treated with 75 g ai ha-1 of halosulfuron-methyl at the mowed, pre-flowering and flowering stages, respectively in plants with established rhizomes. The herbicide was effective in controlling the aboveground growth, however, subsequent emergence of new growth from the rhizome confirms the failure of the herbicide to kill the rhizome. In contrast, application of 75 g ai ha-1 of halosulfuron-methyl provided 100% mortality in plants treated at seedling and pre-flowering stage in plants without established rhizomes. (ii) Another herbicide with an alternate mode of action, florpyrauxifen-benzyl, was assessed at different growth stages again using plants with and without established rhizomes. Results indicate that a single application of florpyrauxifen-benzyl is effective at controlling C. aromaticus seedlings, but not effective at controlling plants with established rhizomes. In summary, this thesis has increased the fundamental knowledge about the ecology of C. aromaticus which will feed into designing of management strategies. Likewise, new tools established in the form of mechanical and chemical control and improving the methods currently used to manage populations will advance the capacity to effectively manage C. aromaticus in the future. Although this investigation is based on a relatively focussed suite of issues relevant to tropical north Queensland, where there is an immediate application of the research outcomes from this study, it is anticipated that they will also inform weed management strategies more broadly in a range of similar environments throughout the world.

Contemporary applications of Fresco : The narrative of the artist
- Authors: Chappell, Annette
- Date: 2017
- Type: Text , Thesis , PhD
- Full Text:
- Description: Fresco is a vehicle for powerful and enduring forms of cultural storytelling; it references universal narrative themes. The research objective of this project is to achieve a contemporary application of fresco through exploration and transgression of traditional material, pictorial forms and functions. In this transgression, the artist locates a personal narrative, through the immersive methods of autoethnographic inquiry and from the epistemological position of material thinking and production. The contemporary application of fresco is arrived at by interrogating the traditional methods, materials and intentions of fresco as recorded in fifteenth-century Europe and with reference to what other contemporary practitioners in this field have achieved. Materials knowledge and methods gained through on-site material conservation of lime plaster fresco is an impetus to this project and has engendered a focus on re-purposing and re-imagining the media in contemporary and personal expressions. The narrative of the artist is arrived at through materials thinking in fresco methodology, and through an interpretive autoethnographic analysis of a personal archive or studio text consisting of visual and textual material. The studio text is regarded as a unique ethnographic artefact of personal significance. The new term of ‘studio text’ for practice-led research is proposed to differentiate practice-led language and forms from the sociological or positivist terminology of ‘fieldwork notes’ or ‘data’. Autoethnographic methodology is disrupted to incorporate the indwelling practices of material thinking and immersive writing (ekphrasis) and drawing (enstasis). Through the integration of these methodologies, interpretations of the studio text are enacted concurrently with material production. Materials and motifs are selected for personal significance and resonance, and constructed as part or full frescoes. The material outcomes of this integration of methodologies are described as Visual Diaries and publicly exhibited. The documentation of integrated methodology in this project may contribute to emergent thinking in practice-led research.

Canonical Duality Theory for Global Optimization problems and applications
- Chen, Yi
- Authors: Chen, Yi
- Date: 2015
- Type: Text , Thesis , PhD
- Full Text:
- Description: The canonical duality theory is studied, through a discussion on a general global optimization problem and applications on fundamentally important problems. This general problem is a formulation of the minimization problem with inequality constraints, where the objective function and constraints are any convex or nonconvex functions satisfying certain decomposition conditions. It covers convex problems, mixed integer programming problems and many other nonlinear programming problems. The three main parts of the canonical duality theory are canonical dual transformation, complementary-dual principle and triality theory. The complementary-dual principle is further developed, which conventionally states that each critical point of the canonical dual problem is corresponding to a KKT point of the primal problem with their sharing the same function value. The new result emphasizes that there exists a one-to-one correspondence between KKT points of the dual problem and of the primal problem and each pair of the corresponding KKT points share the same function value, which implies that there is truly no duality gap between the canonical dual problem and the primal problem. The triality theory reveals insightful information about global and local solutions. It is shown that as long as the global optimality condition holds true, the primal problem is equivalent to a convex problem in the dual space, which can be solved efficiently by existing convex methods; even if the condition does not hold, the convex problem still provides a lower bound that is at least as good as that by the Lagrangian relaxation method. It is also shown that through examining the canonical dual problem, the hidden convexity of the primal problem is easily observable. The canonical duality theory is then applied to dealing with three fundamentally important problems. The first one is the spherically constrained quadratic problem, also referred to as the trust region subproblem. The canonical dual problem is onedimensional and it is proved that the primal problem, no matter with convex or nonconvex objective function, is equivalent to a convex problem in the dual space. Moreover, conditions are found which comprise the boundary that separates instances into “hard case” and “easy case”. A canonical primal-dual algorithm is developed, which is able to efficiently solve the problem, including the “hard case”, and can be used as a unified method for similar problems. The second one is the binary quadratic problem, a fundamental problem in discrete optimization. The discussion is focused on lower bounds and analytically solvable cases, which are obtained by analyzing the canonical dual problem with perturbation techniques. The third one is a general nonconvex problem with log-sum-exp functions and quartic polynomials. It arises widely in engineering science and it can be used to approximate nonsmooth optimization problems. The work shows that problems can still be efficiently solved, via the canonical duality approach, even if they are nonconvex and nonsmooth.

The effects of playing Nintendo Wii on depression, sense of belonging, social support, and mood among Australian aged care residents : A pilot study
- Authors: Chesler, Jessica
- Date: 2015
- Type: Text , Thesis , Masters
- Full Text:
- Description: Adults aged 65 years or older constitute the fastest growing age group worldwide, leading to greater numbers of people requiring care in residential facilities. Adults in these facilities have higher levels of depression, lower levels of social support, and lower levels of sense of belonging compared with older adults living in the community. Research has begun to assess the effectiveness of interventions aimed at improving the mental health of aged care residents. Within this population, cognitive and physical benefits of playing video games have been documented in the literature, as well as greater social interaction, and decreased loneliness. The aim of the current study was to investigate the effectiveness of playing Wii bowling twice weekly, with up to 3 other residents, for 6 weeks. An Australian sample of 31 women and 8 men between the ages of 65 and 95 years (Mean age = 85.68, SD = 9.62) were randomised to either a treatment or control group based on their place of residence. The residents completed demographic information, The Veterans Affairs Saint Louis University Mental Status Exam, the Geriatric Depression Scale Short Form, the Social Provisions Scale, and three visual analogue scales to measure sense of belonging and mood. These scales were completed pre-intervention (0 weeks), postintervention (6 weeks), and at 2-month follow up (14 weeks). Qualitative data on social interaction between group members was also collected at weeks 1, 3, and 6. Results did not support the use of the Wii to improve residents’ self-reported levels of depression, social support, sense of belonging, or mood. Social interaction increased over the 6 weeks, as measured by interaction analyses and also residents’ comments. Overall, findings indicate that Wii bowling may be a useful intervention as part of a comprehensive care program to increase social interaction within aged care. Pervasive environmental problems associated with aged care, as well as participant characteristics, may have reduced the effectiveness of the intervention program.

The acute effects of aerobic exercise on Leukocyte Telomere biology
- Authors: Chilton, Warrick
- Date: 2018
- Type: Text , Thesis , PhD
- Full Text:
- Description: Doctor of Philosophy
- Description: Habitual exercise is unequivocally associated with decreased all-cause mortality and morbidity. Despite the strength of the association, a large part of the decreased risk is physiologically unaccounted for. Accumulating evidence indicates that leukocyte telomere length (LTL) may be one such explanatory mechanism. Telomeres are specialized deoxyribonucleic acid (DNA) sequences located at chromosomal ends where they protect the genomic DNA from enzymatic degradation. Excessive and/or premature telomere shortening in leukocytes is associated with a host of chronic diseases and impaired immune function. Observational associations exist between LTL and habitual physical activity/exercise in multiple cohorts. However, correlation does not imply causal story and the underpinning mechanisms behind the association are unclear. The current consensus is that long-term exercise-induced reductions in oxidative stress and inflammation mediate the association. The acute dynamics of telomere biology are poorly understood; however, a growing body of evidence suggests that telomeres may be amenable to acute modulation via expression of telomereassociated genes and microRNAs. Accordingly, the overarching aim of this thesis was to characterize the acute effects of aerobic exercise on leukocyte telomere biology.

The warrior woman in contemporary romance fiction

- Description: Master of Arts by Research
- Description: The warrior woman is a recurring figure in myth and history. She could be seen as an ambiguous character as she challenges patriarchal assumptions about gender roles with her capability for masculine aggression while being recognisably female and “feminine”. In the new millennium, she has reappeared as the action heroine in films, televisions, comics and video games and she has also infiltrated romance fiction, a genre often considered one of the most conservative genres in terms of gender roles and equality. The Silhouette Bombshell line was created by the multinational publisher Harlequin to capitalise on the popularity of “action heroines” in popular culture. The romance genre, perhaps the most derided of all scorned literature, is often accused, particularly by feminist critics, of reinforcing the patriarchal structure of society. This thesis examines how this character type in romance fiction can provide a means to question and even subvert traditional or patriarchal gender expectations. It will undertake the close examination of the first six books of the Athena Force series, which were published in 2004-2005 as part of the Silhouette Bombshell line. Both the warrior woman and the romance genre are defined and historically reviewed, together with an outline of the workings of the contemporary romance industry with regard to category, genre and publishing guidelines. There follows a detailed analysis of the warrior woman character as she appears in the Athena Force series with regard to agency, violence, sisterhood, professional career, performance of femininity and romantic relationships.
