- Description: The primary aim of Surf Life Saving Australia (SLSA), through their State and Territory bodies is to provide safe coastal environments for Australian beach goers. With over 312 affiliated clubs across Australia, SLSA provides an opportunity for primary school aged children (Nippers) to experience water safety and aquatic education in an open water environment. Nippers in the Under 8-Under 13 years age groups are involved in a participation-based education program known as the Junior Development Program (JDP), which aims to develop skills required for future lifesaving (Giles & Slade, 2012). The overall aim of this research was to identify and explore the barriers and enablers to involvement in SLSA’s JDP from the perspective of the participants, their parents/carers and those involved in the delivery of the program. Utilising a multiphase mixed method design, 341 Nippers from eight surf lifesaving clubs in New South Wales completed a questionnaire and 30 interviews were conducted – 19 with parents/carers from seven of the eight participating lifesaving clubs, and 11 Age Managers from six of the eight clubs. The findings indicated that the Nippers perceived most lifesaving skills were important and were happy/very happy to be learning about safety of themselves and how to assist others in the surf. Most concerns related to unknowns in terms of sea creatures and adverse weather conditions like storms and lightening. Interviewees believed Nipper participation was based on interpersonal and intrapersonal reasons, with socialisation a positive aspect of the program. In line with common fears reported by Nippers, interviewees reported unfavourable environmental conditions, including big surf, cold weather, weed and stingers, as barriers to participation. The findings and opinions from those involved in the JDP provide insights into barriers and enablers to participation in the program, which is intended to provide important guidance for future delivery of the JDP across Australia.

Application of molecular diagnostic methods for the detection and quantification of Fasciola hepatica infection in cattle faecal samples
- Authors: Thakur, Sameer
- Date: 2020
- Type: Text , Thesis , Masters
- Full Text:
- Description: Fasciola hepatica, commonly known as liver fluke, is a globally distributed trematode causing significant production losses in ruminant livestock. Due to reduced drug efficacy, there is a need for appropriate diagnostic tools, which would allow alternative management practices to be developed and minimize economic losses. The traditional ‘gold standard’ method for diagnosis, faecal egg count (FEC), is associated with low sensitivity when diagnosing F. hepatica infection in livestock using faecal samples. The present study aimed to compare the sensitivity and specificity of the molecular diagnostic methods [conventional PCR (cPCR), Loop Mediated Isothermal Amplification (LAMP) and quantitative real time PCR (qPCR)] with the conventional diagnostic method FEC, for detecting F. hepatica infection using cattle faecal samples. Faecal samples were collected from 94 experimentally-infected cattle 12 weeks post infection and 40 faecal samples were collected from cattle with no previous history of F. hepatica infection, as a comparative control. The sensitivity of conventional PCR, LAMP and qPCR was 86.2%, 87.2% and 96.8% respectively, which was similar to the faecal egg count (97.9%). While the specificity of all the molecular methods were 97.5%, and for FEC the specificity was 100%. The potential advantage of these molecular diagnostic tests, with further development, suggest they may be a viable alternative diagnostic test when compared to FEC. In addition, a pilot study was conducted to evaluate the potential use of a commercial snail trap in catching and detecting the intermediate host of F. hepatica in irrigated farmland, as an alternative management strategy. However, under the parameters tested in these experiments, the use of commercial snail traps to catch the intermediate host of F. hepatica from farm irrigation channels was shown to be ineffective.

- Description: The objective of the research project is to contribute to the understanding of the auditing profession in Vietnam. In particular, it provides information on the challenges facing auditors in an emerging economy where economic transformation is in progress and where auditing, as a profession, is under development. Auditors operate in an environment of conflicting priorities where they must maintain independence and objectivity in discharging their responsibilities to stakeholders and society. In Vietnam, the audit profession only came into existence in 1986 when the country embarked on its new economic model. Whilst studies have been conducted on the status of current accounting practice in Vietnam, studies regarding the audit profession have been limited. In this research project an examination of the issues affecting audit quality in Vietnam are investigated and suggestions for changes to address the deficiencies are made. In particular, the project focuses on the relevance and appropriateness of the education of auditors. A national survey of accountants, auditors and accounting academics in Vietnam was undertaken. The survey results indicate that in Vietnam there are deficiencies in audit practices over and above those commonly observed in other countries. These deficiencies are the result of the unique history of Vietnam, the current stage of economic development and the education system for auditors. From an auditing perspective, the slow adaptation of the education system to the new economic environment is having negative effects on accounting graduates and their employment prospects. Although inadequate training was identified as the single most important factor affecting audit quality, the ineffective enforcement regime was also a contributing factor. This research project indicates that there is a need for an overhaul of the current education system in Vietnam and for universities to develop an accounting and auditing curriculum that meets the needs of employers while complying with government’s education objectives and international standards of auditing and accounting.

Australian home care quality : a political tango
- Authors: Mee, Jenny

- Type: Text , Thesis , PhD
- Full Text:
- Description: The performance of Australian home care and how it is enacted has been significantly impacted by the economic and political challenges since the announcement of the Aged Care Reforms in July 2012 and the launch of the National Disability Insurance Scheme in July 2013. As a result, the home care business arena has changed, and the effects are being felt as the marketplace shifts, and businesses adapt to new policy directions. The purpose of this research study was to investigate the social context of Australian home care, and to collect information regarding how home care (under the various auspices of government funded and privately funded) service provision is enacted in terms of quality during this time of change. The qualitative research process for this study involved critical reflexive practice and face-to-face semi-structured interviews of 10 home care business leaders from the states of Queensland and Victoria. In listening to the voices of the participants, this research study sought to develop new discursive approaches in order to understand the practice of caring for the Australian community’s most vulnerable people – those who are frail, aged, and for those who have ill-health or a disability. The analytical framework adopted for this study used a post-structural discourse analysis, which was informed by the work of French philosopher Michel Foucault and other contemporary theorists. The philosophical framework of governmentality and discourse analysis helped to situate the voice of the participants at a time when new ideas and the ways of conducting the business of home care are emerging. In using this approach to analyse the data, it became apparent that the discursive practices that had been instituted by government in the home care sector had been constructed to remove progressive inclusionary policies that were contrary to the democratic principles of governing. The research study’s findings reveal the problematic changes that impact on business but more so for consumers as the rules are interpreted. By using the metaphor of ice dancing, the study problematized the leadership of government and the challenges participants faced in maintaining quality service provision in the home care arena. What emerged was the dance of a political tango. These leaders in the arena revealed the importance of knowing when to lead and when to push back. Like the different genres of tango, there are different ways of viewing the world of home care and performing in its different spaces, and there are other ways of viewing quality in caring service provisions. By participating in the research, the participants highlighted the need of being inclusive to hearing and seeing all performers in the arena of home care regardless of social or geographical positioning. This research concludes that hearing and acting on the voices from the wider home care arena continues to be necessary in order to inform future policy direction for quality performance improvements for Australia’s consumers of home care and to move away from home care traditions of governing and ruling. The research additionally advocates for more inclusive governing approaches through more even distribution of power in consultative processes, research, oversight in the marketplace and access to resources for all groups. This thesis is a contribution to creating a new political dance in the space of Australia’s home care politics.

Being a parent, but not : the role of foster and kinship carers in supporting children and young people
- Authors: Cooper, Kimberlea
- Date: 2020
- Type: Text , Thesis , PhD
- Full Text:
- Description: Home-based carers play an important role in the lives of children and young people. In Victoria, Australia, home-based care is now the most common form of alternative care, reflecting national and international trends. However, home-based care does currently face some challenges, such as shortages of carers. Therefore, strengthening this form of care through the training and support of foster and kinship carers is a key priority of Victoria’s reforms of child and family services. In the context of a university-industry collaboration, the current research drew upon the expertise of sixteen foster and kinship carers in the Central Highlands region of Victoria. Using constructivist grounded theory, the research sought to understand how carers support children and young people and how they see their role. In addition, the research sought carers’ perspectives on their interactions with the Out-of-Home Care (OOHC) system, including what they find supportive and challenging. The research revealed that home-based carers see some elements of their role as parenting, and others as going beyond parenting. The carers utilise principles of trauma-informed care to support children and young people, but do not experience trauma-informed support from the OOHC system. This discrepancy suggests that the implementation of trauma-informed care has the potential to increase pressure on home-based carers if it is only encouraged at the interpersonal level between carers and children and does not incorporate associated systems-level change. Therefore, this research proposes that whilst micro-level support and training for carers is necessary and useful, it is crucial to move beyond such initiatives to make macro-level reform. This research also raises doubts regarding the capacity of home-based care to become fully trauma-informed due to potential incompatibilities with the current risk-averse and deficit-oriented paradigm of the child protection system.

- Type: Text , Thesis , PhD
- Full Text:
- Description: This thesis describes an explanatory sequential mixed-methods research project that investigated the changes to student social capital indicators resulting from an outdoor educational program, Future Maker, delivered to Victorian government school students. A systematic review of literature found minimal evidence of research relating to the change to social capital indicators as a result of programs that deliver outdoor education curriculum. The initial chapters of this thesis explore research on outdoor residential schools and the development of the Future Maker program as an alternative form of outdoor education curriculum design. Quantitative data were gathered from 287 students in the form of the Life Effectiveness Questionnaire (LEQ), over a 12-month period. Students completed the LEQ on three separate occasions: Day 1 of the program, Day 12 of the program, and 6 months after the program. Furthermore, qualitative data were gathered using a semistructured interview process. Twenty-eight students and seven teachers were randomly selected from participating schools to partake in the interviews. The final sections of the thesis present and discuss the findings from the quantitative and qualitative data that provided sufficient evidence that showed a significant increase in effect size for the social capital indicators of communication, relationships, group processing, networking and leadership. Furthermore, the research indicated that the domestic chores undertaken by students on an outdoor education program contributed to how social capital is learnt in an outdoor educational context. Moreover, the research positions outdoor education as a subject with content and pedagogy rather than a discipline and argues that outdoor education as a standalone subject has been sitting in plain sight. Finally, it concluded that a purpose-designed outdoor education program, which is built using a framework for curriculum development, can develop positive indicators for social capital.

Citizen science: Knowledge, networks and the boundaries of participation
- Authors: Bonney, Patrick
- Date: 2020
- Type: Text , Thesis , PhD
- Full Text:
- Description: The water-related challenges facing humanity are complex and urgent. Although solutions are not always clear, involving the public in localised knowledge production and policy development is widely recognised as a critical part of this larger effort. Such public engagement is increasingly achieved through “citizen science”—a practice that involves non-professionals in scientific research and monitoring. Academic literature has recognised that, while citizen science is both important and necessary to strengthen environmental policy, its acceptance and successful implementation is a difficult governance challenge. Researchers agree that overcoming this challenge depends on the ability of volunteers, coordinators, scientists and decision-makers to work together to convert the potential of citizen science into practice. However, little is known about the collaborative relationships or the broader social contexts that shape and define the practice. To address these shortfalls, this thesis advances a conceptual framework for the relational analysis of citizen science that illustrates social networks and the boundaries between expert and community-based knowledge as critical sites of investigation. Through its multi-phase and mixed-methods research design, the findings of this thesis shed light on the contributions of citizen science to key waterway governance objectives, including the social, political and cultural factors that influence its acceptance and uptake in governance contexts. By unpacking the relational dimensions of citizen science, this thesis provides both theoretical and practice-based insights into how actors within and outside citizen science programs work together to achieve collective aims to engender stronger connections between science, society and policy. This thesis will benefit practitioners, policymakers and participatory advocates interested in achieving practical social change in efforts to understand and manage natural resources.

Conflict and conservation : sharing the costs and benefits of tiger (Panthera tigris) conservation in communities adjacent to tiger reserves in Nepal
- Authors: Bhattarai, Babu
- Date: 2020
- Type: Text , Thesis , PhD
- Full Text:
- Description: Human wildlife conflict (HWC) is a highly studied but unresolved aspect of wildlife management. To further knowledge on HWC, this study used a multidisciplinary approach to investigate HWC implications for local people living adjacent to two key tiger conservation reserves in Nepal. The study also assessed the potential to redistribute financial benefits accruing from predator conservation to those bearing costs through associated HWC. Secondary data and anecdotal reports suggest that local people experience significant direct and indirect costs from predator conservation through livestock losses following attacks by common leopards and Bengal tigers, and additionally, crop losses due to their prey species plus two mega herbivores (elephant and one-horned rhinoceros). To investigate this situation, data regarding HWC incidents and costs were sourced through interviews with 422 local households, direct observations, and stakeholder interviews. Collected data included livestock loss (5-year time-period) and crop loss (1-year time-period). Complementary direct observation data collated livestock loss and crop damage for 12 months. Interviews were conducted also with park visitors (N=387) and tourism business owners (N=74). Results showed that tigers are involved in significantly fewer depredation events compared to leopards. Leopards predominantly killed small to medium livestock whereas tigers selected both small to medium and large sized livestock. Livestock depredation events occurred more frequently in livestock corrals relative to forest zones or crop fields. Rates of livestock losses per household per year self-reported during interviews with local people were found higher when compared to those observed by direct measurement. Prey species of tigers and leopards (most often wild boar and chital) were involved in more frequently in crop raiding events, and caused more crop damage, when compared that caused by mega herbivores. Quantities of crops lost per household were lowest in communities where effective physical barriers to wildlife were present. Park visitors and tourism business owners indicated willingness to pay for conservation of tigers and for compensation of farmers for the losses caused by tigers and their prey species. Study findings support several key recommendations proposed to mitigate negative HWC effects in the study area. These include financial support for local communities to build predator proof livestock corrals and establishment of effective physical barriers at the park borders. A dedicated tariff for park visitors and a levy for tourism business owners are also recommended to fund ongoing predator conservation and support financial compensation for local farmers affected by HWC.

Creating safety : intersection of healthcare and police response to violence against immigrant south asian women in British Columbia : a service provision model
- Authors: Kaur, Harjit

- Type: Text , Thesis , PhD
- Full Text:
- Description: Background Intimate Partner Violence (IPV), is an internationally prevalent health and safety issue impacting women. Immigrant South Asian women (ISAW) in British Columbia (BC) remain vulnerable to serious injuries and homicides despite efforts of healthcare and police services. It is critical to improve these responses. Knowledge of the challenges to responses can inform and improve services and the well-being of ISAW. Aims This study aimed to explore the needs of ISAW and the challenges of healthcare and police responses, how these may inform responses and to compare the perspectives of survivors, responders and experts to improve the health and safety of ISAW. Methods Design: a two-phased, mixed methods study. Phase 1: a purposive sample of 4 focus groups of 22 ISAW survivors from four cities in BC. An additional focus group involved five subject matter experts. Also conducted were seven face-to-face semi-structured interviews with twelve key informants. Phase 2: a convenience sample of 128 provincial responders completed an online survey. Results The key emerging themes for survivors were the difficulties in identifying and disclosing IPV and the responses to IPV. Responders identified the gaps in services, culturally and linguistically inappropriate policies and uncoordinated and non-collaborative efforts. For the ISAW, perceptions, fears, and socio-cultural impediments hindered their disclosure of IPV. They required culturally and linguistically trauma informed responses, policies and practices to overcome multiple and complex challenges. Co-ordinated, collaborative systemic responses to improve the health and safety of ISAW were identified by all participants, including appropriate risk assessment. Conclusion This study adds to current knowledge by contributing to the understanding of IPV of ISAW from different perspectives: ISAW survivors, responders and experts. This knowledge offers potential improvements to services and policy developments to reduce the health and safety risks to IPV survivors.

- Description: Background Intimate Partner Violence (IPV), is an internationally prevalent health and safety issue impacting women. Immigrant South Asian women (ISAW) in British Columbia (BC) remain vulnerable to serious injuries and homicides despite efforts of healthcare and police services. It is critical to improve these responses. Knowledge of the challenges to responses can inform and improve services and the well-being of ISAW. Aims This study aimed to explore the needs of ISAW and the challenges of healthcare and police responses, how these may inform responses and to compare the perspectives of survivors, responders and experts to improve the health and safety of ISAW. Methods Design: a two-phased, mixed methods study. Phase 1: a purposive sample of 4 focus groups of 22 ISAW survivors from four cities in BC. An additional focus group involved five subject matter experts. Also conducted were seven face-to-face semi-structured interviews with twelve key informants. Phase 2: a convenience sample of 128 provincial responders completed an online survey. Results The key emerging themes for survivors were the difficulties in identifying and disclosing IPV and the responses to IPV. Responders identified the gaps in services, culturally and linguistically inappropriate policies and uncoordinated and non-collaborative efforts. For the ISAW, perceptions, fears, and socio-cultural impediments hindered their disclosure of IPV. They required culturally and linguistically trauma informed responses, policies and practices to overcome multiple and complex challenges. Co-ordinated, collaborative systemic responses to improve the health and safety of ISAW were identified by all participants, including appropriate risk assessment. Conclusion This study adds to current knowledge by contributing to the understanding of IPV of ISAW from different perspectives: ISAW survivors, responders and experts. This knowledge offers potential improvements to services and policy developments to reduce the health and safety risks to IPV survivors.

Creative activation of the past: Mechanics' Institutes, GLAM, heritage, and creativity in the twenty-first century
- Authors: Tsilemanis, Amy
- Date: 2020
- Type: Text , Thesis , PhD
- Full Text:
- Description: This is an interdisciplinary, mixed-method thesis that explores contemporary curation as a means to creatively activate heritage collections and places. The central case study is Ballaarat Mechanics’ Institute (BMI), in Ballarat, Australia, where practice and action-led research was undertaken by the curator over the three-year period 2016–2019. Creative connections between five interlinked areas are critically examined: heritage; curatorial practice, by which heritage sites, collections and experiences are managed; historic cultural organisations; their city contexts; and the ways in which such cultural work is valued. The framework for analysis encompasses museology, critical heritage, and approaches to cultural value. Contemporary urban Mechanics’ Institutes (MIs) are placed in the museum context both through historic parallels and their contemporary positioning in the GLAM (galleries, libraries, archives and museums) industry sector. This is in order to ask how heritage collections, and the organisations that house and present them, can creatively connect with the publics they serve with greater connectivity and relevance. Exhibitions and events held at BMI within Ballarat city are treated as case studies. Together with qualitative interviews with staff in the Ballarat GLAM sector and urban MIs, insights derived illuminate the role and challenges of such cultural organisations in the twenty-first century. It is argued that, when employing the practice and energy of the curator, creative activations have the potential to open new points of entry to, and provide alternative perspectives upon, heritage places and collections. This is achieved through arts practice, organisational thinking, and bringing to life the links between past, present and future. In this process, new and dynamic measures of value can be explored and create dialogic encounters between people, heritage and ideas.

Deriving value from health 2.0 : A study of social media use among healthcare providers
- Authors: Ukoha, Chukwuma
- Date: 2020
- Type: Text , Thesis , PhD
- Full Text:
- Description: Social media applications are increasingly being used by healthcare providers because of the numerous communication, information, and public relations benefits they offer. Despite the growing adoption of social media in healthcare settings, its specific uses and value propositions are not well understood. To ensure continuous improvement, social media performance must be measured. However, little is known about the tools, techniques and yardsticks used to measure social media performance in healthcare settings. This study adopts qualitative research methods to explore healthcare providers’ perspectives on the value of social media in healthcare settings. Australian healthcare providers, from organizations of different sizes and locations, who use social media, were interviewed and the transcripts thematically analysed. The results demonstrate the uses of social media in health care, as well as the steps and techniques in social media measurement. Based on the findings, it is clear that the ability of social media to support various activities in healthcare settings makes it valuable to healthcare providers. Drawing on Bakhtin’s ‘theories’ and Stevens’s theory of measurement, this study theorises on the value of social media and introduces a protocol for measuring social media performance in healthcare settings. As one of the first studies to apply Bakhtinian ideas to consumer health informatics, this study has the potential to pave a new approach to conceptualizing the role of social media, particularly in healthcare settings. By using Stevens’s theory of measurement to explore the yardsticks suitable for social media measurement, this study provides a more nuanced framework for measuring the value of social media in healthcare settings.

- Description: Intelligent Traffic Systems (ITS) can manage on-road traffic efficiently based on real-time traffic conditions, reduce delay at the intersections, and maintain the safety of the road users. However, emergency vehicles still struggle to meet their targeted response time, and an ITS is vulnerable to various types of attacks, including cyberattacks. To address these issues, in this dissertation, we introduce three techniques that enhance the service quality and reliability of an ITS. First, an innovative Emergency Vehicle Priority System (EVPS) is presented to assist an Emergency Vehicle (EV) in attending the incident place faster. Our proposed EVPS determines the proper priority codes of EV based on the type of incidents. After priority code generation, EVPS selects the number of traffic signals needed to be turned green considering the impact on other vehicles gathered in the relevant adjacent cells. Second, for improving reliability, an Intrusion Detection System for traffic signals is proposed for the first time, which leverages traffic and signal characteristics such as the flow rate, vehicle speed, and signal phase time. Shannon’s entropy is used to calculate the uncertainty associated with the likelihood of particular evidence and Dempster-Shafer (DS) decision theory is used to fuse the evidential information. Finally, to improve the reliability of a future ITS, we introduce a model that assesses the trust level of four major On-Board Units (OBU) of a self-driving car along with Global Positioning System (GPS) data and safety messages. Both subjective logic (DS theory) and CertainLogic are used to develop the theoretical underpinning for estimating the trust value of a self-driving car by fusing the trust value of four OBU components, GPS data and safety messages. For evaluation and validation purposes, a popular and widely used traffic simulation package, namely Simulation of Urban Mobility (SUMO), is used to develop the simulation platform using a real map of Melbourne CBD. The relevant historical real data taken from the VicRoads website were used to inject the traffic flow and density in the simulation model. We evaluated the performance of our proposed techniques considering different traffic and signal characteristics such as occupancy rate, flow rate, phase time, and vehicle speed under many realistic scenarios. The simulation result shows the potential efficacy of our proposed techniques for all selected scenarios.

Exploring the interior : performing situated responsibility in postcolonising Australia

- Full Text:
- Description: Theatre is a powerful way to investigate the operation of borders due to its live, immediate focus on representation and its potential to test a society’s boundaries. This practice-led research incorporates a performance and an exegesis to ask, ‘How can site-specific theatre that investigates the performance of borders and heterotopia enhance understanding of individual responsibility in postcolonising Australia?’ I take the term postcolonising from Aileen Moreton-Robinson, who argues that the beneficiaries of settler-colonialism (such as myself) must accept responsibility for the past before attempting to address its injustices. As an artist, I am inspired by anthropologist, Deborah Bird Rose, who privileges storytelling as a way of breaking boundaries between the past and present. Michel Foucault coined the term heterotopia (other place) to denote a single real space that juxtaposes several sites that are incompatible. This evokes the contemporary Australian situation of contested sovereignty. As Joanne Tompkins argues, heterotopic theatre can enact such a space in order to raise awareness and work towards societal change. My research demonstrates this both theoretically and practically. My exegesis crosses borders to create a heterotopia by juxtaposing past, present and possible futures, stories and theoretical understandings from diverse sources. The performance created at my home, rather than in a theatre, layers family, local, Australian and international histories to highlight the continuum between the personal and political, and to question current structures of power and knowledge. I use site-specific theatre to diminish the boundaries between performer and audience, creating a visceral heterotopia that facilitates a deeper understanding of personal responsibility in the context of postcolonising Australia.

FEM and XFEM approaches to Investigate the Hydromechanical Interactions within a jointed soft-rock slope
- Authors: Shaghaghi, Tahereh
- Date: 2020
- Type: Text , Thesis , PhD
- Full Text:
- Description: One of the most significant challenges of open-cut mining is to provide stability for the excavated slopes. Unrealistic predictions of the slopes’ behaviour during and after mining operations can lead to the failure of slopes, and this may pose a threat to human lives, the economy, and the environment. By excavating soft rock masses in open-cut mines, pre-existing joints can open and new joints can form behind excavated slopes. This phenomenon is due to the geotechnical character of the materials and stress relief movements of the excavated slopes. The stability of slopes in the rock masses is significantly influenced by the existence of discontinuities such as joints. The water flows in the opened joints can change the pore water pressure distribution in the slopes. The interaction between the joints and the water may impose different loading scenarios on the open-cut mines and put the safety of mining operations at risk. The analysis of slope stability can become more complicated because of the presence of water, discontinuities, and their interaction within the slopes in open-cut mines. This study investigates the hydromechanical interactions in the saturated jointed slopes due to pore water pressure changes. The second-largest open-cut mine in Australia, the Yallourn brown coal open-cut mine located in Victoria, was chosen as the case study for this research. In this study, several coupled pore fluid diffusion and stress-strain analyses are conducted using the extended finite element method (XFEM) in conjunction with the finite element method (FEM). This study firstly examines a joint aperture and pore water pressure changes of the excavated jointed slope due to installing a drainage system and backfilling in front of the slope. Secondly, a series of sensitivity analyses are carried out on the pore water pressure distribution changes to the variation of the permeability magnitude of the material and leakage properties of the joint surfaces. Finally, to control the pore water pressure of the saturated jointed slope, a series of drainage systems is designed. The arrangement and length of the drains are optimised by conducting a series of sensitivity analyses on the leakage properties of the joint and the permeability of the soft rock.

- Full Text:
- Description: Online fraud causes billions of dollars in losses for banks. Therefore, online banking fraud detection is an important field of study. However, there are many challenges in conducting research in fraud detection. One of the constraints is due to unavailability of bank datasets for research or the required characteristics of the attributes of the data are not available. Numeric data usually provides better performance for machine learning algorithms. Most transaction data however have categorical, or nominal features as well. Moreover, some platforms such as Apache Spark only recognizes numeric data. So, there is a need to use techniques e.g. One-hot encoding (OHE) to transform categorical features to numerical features, however OHE has challenges including the sparseness of transformed data and that the distinct values of an attribute are not always known in advance. Efficient feature engineering can improve the algorithm’s performance but usually requires detailed domain knowledge to identify correct features. Techniques like Ripple Down Rules (RDR) are suitable for fraud detection because of their low maintenance and incremental learning features. However, high classification accuracy on mixed datasets, especially for scalable data is challenging. Evaluation of RDR on distributed platforms is also challenging as it is not available on these platforms. The thesis proposes the following solutions to these challenges: • We developed a technique Highly Correlated Rule Based Uniformly Distribution (HCRUD) to generate highly correlated rule-based uniformly-distributed synthetic data. • We developed a technique One-hot Encoded Extended Compact (OHE-EC) to transform categorical features to numeric features by compacting sparse-data even if all distinct values are unknown. • We developed a technique Feature Engineering and Compact Unified Expressions (FECUE) to improve model efficiency through feature engineering where the domain of the data is not known in advance. • A Unified Expression RDR fraud deduction technique (UE-RDR) for Big data has been proposed and evaluated on the Spark platform. Empirical tests were executed on multi-node Hadoop cluster using well-known classifiers on bank data, synthetic bank datasets and publicly available datasets from UCI repository. These evaluations demonstrated substantial improvements in terms of classification accuracy, ruleset compactness and execution speed.

Grand designs, grim reality : political representation, competition and equity in regional Victoria

- Type: Text , Thesis , PhD
- Full Text:
- Description: This work brings new understanding to the subtle ways in which the ability of one rural community to change is curtailed by self-reinforcement of an ideology not entirely of their own making. In a political environment where economic returns and population growth appear to be the true indicators of value and success, the struggle of some rural communities to change a long term and seemingly intractable trajectory of decline is well documented. The historical importance of rural communities as a place where food and fibre are grown has been challenged by market forces, climatic conditions and the relative growth of cities and service-based industries over the last three decades. To people in rural areas experiencing population stasis or decline, the situation appears to be a competition that is not being won at a local level. This thesis employs critical ethnography to understand a layered investigation of the ideological paradigms internalised by leaders in this community in a place-based setting to explore how this influences political advocacy and action. The work focusses on the Wimmera Southern Mallee region in Victoria, Australia with a particular emphasis on the city of Horsham as the major regional centre. The purpose of this work is to understand how ideology and behaviours are used to reinforce a system of power that is dominated by prestige leadership. The work also considers how external political and ideological influences may further reinforce on to leaders in the region a set of values and expectations which negatively impact on action and outcomes. The findings of this work have implications for rural community engagement, regional development, place-based initiatives and regional advocacy.

Herbicide application strategies for wild radish management in Imidazolinone tolerant faba bean
- Authors: Welgama, Amali

- Type: Text , Thesis , PhD
- Full Text:
- Description: The extensive and continual use of herbicides in cropping situations has inevitably led to the phenomenon of "herbicide-resistance" in weeds and this has become one of the most challenging issues in modern agriculture. Herbicide-tolerant crops (HTC) were introduced to diversify weed management practices, but the lack of integrated weed management strategies, along with the continuous use of the same herbicide mode of action (MOA) demanded by the HTC has continued to impose selection pressure on weeds to evolve with herbicide resistance. Consequently, this thesis has been focused on the introduction of herbicide MOA combinations into HTC systems in an attempt to reduce the rate of herbicide resistance evolution in weeds. Raphanus raphanistrum is the number one broadleaf weed in Australia, and for this case study, the newly released ALS-inhibiting imidazolinone tolerant faba bean cultivar PBA Bendoc with its conventional cultivar, PBA Samira, were selected as the study species. ALS-inhibiting (imazamox + imazapyr and imazethapyr) and PSII-inhibiting (metribuzin) herbicides were used as the two herbicide MOAs. The herbicide sensitivity of R. raphanistrum was initially evaluated at different growth stages, in glasshouse studies using herbicide-resistant and susceptible biotypes to ALS-inhibiting herbicides. The highest susceptibility was observed at the earliest growth stage regardless of the biotype and Imazamox + imazapyr proved to be more effective in controlling both biotypes compared to imazethapyr. The same two herbicides were tested on faba bean cultivars at different growth stages to assess crop tolerance and identify the herbicide application window. The field trials conducted in 2018 and 2019 showed increased ALS-inhibiting herbicide tolerance in PBA Bendoc compared to PBA Samira even at the most advanced growth stage. Both faba bean cultivars were then evaluated for their tolerance to metribuzin in-crop application at different herbicide rates. Both cultivars responded similarly, showing progressive herbicide damage with increasing application rates. However, the reduced pod number, even at the lowest rate used, flagged the possible yield penalties that may result in using in-crop metribuzin applications. It is thus suggested that metribuzin must be used post sowing pre-emergent (PSPE) respecting the label recommendations. The potential herbicide combinations were then tested on herbicide-resistant R. raphanistrum and PBA Bendoc to evaluate their efficacies. Metribuzin was initially used as PSPE in all combinations, and was to be followed by imazamox + imazapyr applications at the same growth stages of the weed and the crop as in previous experiments. However, 100% control of R. raphanistrum was achieved using metribuzin alone, and thus no second herbicide was required. All the assessed herbicide combinations were tolerated by PBA Bendoc, proving the suitability of these herbicide combinations for incorporation into the PBA Bendoc cropping system. These results led to two potential herbicide combination strategies: (i) herbicide rotations, with metribuzin as PSPE in one year along with another potential herbicide MOA in the following year, (ii) herbicide sequential application, with metribuzin applied at PSPE and imazamox + imazapyr applied at the 2-4 leaf stage if R. raphanistrum plants survived the metribuzin treatment. A seed germination study was conducted under different temperature/photoperiods, pH levels, osmotic potentials, salinity and burial depths to identify the optimal germination conditions for R. raphanistrum. The optimum germination conditions for both herbicide-resistant and susceptible biotypes of R. raphanistrum were found to be 25ºC/15ºC temperature range under 24 hours complete dark. However, the significant interaction between photoperiod and temperature indicated that the seed germination under higher temperatures is less favoured by 24 hours dark conditions regardless of the biotype. An increased moisture stress tolerance in herbicide-resistant seeds was observed, whilst both biotypes reacted similarly to different pH levels and burial depths. In summary, this thesis has elucidated the effectiveness of two herbicide MOAs in controlling R. raphanistrum while addressing the crop tolerance to these herbicide MOA combinations. These findings will help in setting up stewardship guidelines to be used with the PBA Bendoc faba bean cultivar to mitigate the misuse of herbicides, thus ensuring their sustainable application. In addition, the demonstration of differential seed germination requirements of resistant and susceptible R. raphanistrum seeds has provided further information to help with its systematic management. Overall, this study can be used as a case study to investigate herbicide options that can be used in different HT crop cultivars to control a range of weed species.

The field trials conducted in 2018 and 2019 showed increased ALS-inhibiting herbicide tolerance in PBA Bendoc compared to PBA Samira even at the most advanced growth stage. Both faba bean cultivars were then evaluated for their tolerance to metribuzin in-crop application at different herbicide rates. Both cultivars responded similarly, showing progressive herbicide damage with increasing application rates. However, the reduced pod number, even at the lowest rate used, flagged the possible yield penalties that may result in using in-crop metribuzin applications. It is thus suggested that metribuzin must be used post sowing pre-emergent (PSPE) respecting the label recommendations. The potential herbicide combinations were then tested on herbicide-resistant R. raphanistrum and PBA Bendoc to evaluate their efficacies. Metribuzin was initially used as PSPE in all combinations, and was to be followed by imazamox + imazapyr applications at the same growth stages of the weed and the crop as in previous experiments. However, 100% control of R. raphanistrum was achieved using metribuzin alone, and thus no second herbicide was required. All the assessed herbicide combinations were tolerated by PBA Bendoc, proving the suitability of these herbicide combinations for incorporation into the PBA Bendoc cropping system. These results led to two potential herbicide combination strategies: (i) herbicide rotations, with metribuzin as PSPE in one year along with another potential herbicide MOA in the following year, (ii) herbicide sequential application, with metribuzin applied at PSPE and imazamox + imazapyr applied at the 2-4 leaf stage if R. raphanistrum plants survived the metribuzin treatment. A seed germination study was conducted under different temperature/photoperiods, pH levels, osmotic potentials, salinity and burial depths to identify the optimal germination conditions for R. raphanistrum. The optimum germination conditions for both herbicide-resistant and susceptible biotypes of R. raphanistrum were found to be 25ºC/15ºC temperature range under 24 hours complete dark. However, the significant interaction between photoperiod and temperature indicated that the seed germination under higher temperatures is less favoured by 24 hours dark conditions regardless of the biotype. An increased moisture stress tolerance in herbicide-resistant seeds was observed, whilst both biotypes reacted similarly to different pH levels and burial depths. In summary, this thesis has elucidated the effectiveness of two herbicide MOAs in controlling R. raphanistrum while addressing the crop tolerance to these herbicide MOA combinations. These findings will help in setting up stewardship guidelines to be used with the PBA Bendoc faba bean cultivar to mitigate the misuse of herbicides, thus ensuring their sustainable application. In addition, the demonstration of differential seed germination requirements of resistant and susceptible R. raphanistrum seeds has provided further information to help with its systematic management. Overall, this study can be used as a case study to investigate herbicide options that can be used in different HT crop cultivars to control a range of weed species.

- Description: Cyber security, also known as information technology security or simply as information security, aims to protect government organizations, companies and individuals by defending their computers, servers, electronic systems, networks, and data from malicious attacks. With the advancement of client-side on the fly web content generation techniques, it becomes easier for attackers to modify the content of a website dynamically and gain access to valuable information. The impact of cybercrime to the global economy is now more than ever, and it is growing day by day. Among various types of cybercrimes, financial attacks are widely spread and the financial sector is among most targeted. Both corporations and individuals are losing a huge amount of money each year. The majority portion of financial attacks is carried out by banking malware and web-based attacks. The end users are not always skilled enough to differentiate between injected content and actual contents of a webpage. Designing a real-time security system for ensuring a safe browsing experience is a challenging task. Some of the existing solutions are designed for client side and all the users have to install it in their system, which is very difficult to implement. In addition, various platforms and tools are used by organizations and individuals, therefore, different solutions are needed to be designed. The existing server-side solution often focuses on sanitizing and filtering the inputs. It will fail to detect obfuscated and hidden scripts. This is a realtime security system and any significant delay will hamper user experience. Therefore, finding the most optimized and efficient solution is very important. To ensure an easy installation and integration capabilities of any solution with the existing system is also a critical factor to consider. If the solution is efficient but difficult to integrate, then it may not be a feasible solution for practical use. Unsupervised and supervised data classification techniques have been widely applied to design algorithms for solving cyber security problems. The performance of these algorithms varies depending on types of cyber security problems and size of datasets. To date, existing algorithms do not achieve high accuracy in detecting malware activities. Datasets in cyber security and, especially those from financial sectors, are predominantly imbalanced datasets as the number of malware activities is significantly less than the number of normal activities. This means that classifiers for imbalanced datasets can be used to develop supervised data classification algorithms to detect malware activities. Development of classifiers for imbalanced data sets has been subject of research over the last decade. Most of these classifiers are based on oversampling and undersampling techniques and are not efficient in many situations as such techniques are applied globally. In this thesis, we develop two new algorithms for solving supervised data classification problems in imbalanced datasets and then apply them to solve malware detection problems. The first algorithm is designed using the piecewise linear classifiers by formulating this problem as an optimization problem and by applying the penalty function method. More specifically, we add more penalty to the objective function for misclassified points from minority classes. The second method is based on the combination of the supervised and unsupervised (clustering) algorithms. Such an approach allows one to identify areas in the input space where minority classes are located and to apply local oversampling or undersampling. This approach leads to the design of more efficient and accurate classifiers. The proposed algorithms are tested using real-world datasets. Results clearly demonstrate superiority of newly introduced algorithms. Then we apply these algorithms to design classifiers to detect malwares.

- Description: This thesis aims to investigate the impact of workplace guanxi upon knowledge sharing and innovative work behaviour. Knowledge sharing and innovative work behaviour are two behavioural variables which have been linked to various positive individual and organisational outcomes. Against the changing landscape of Chinese higher education, the two behaviours are particularly important for the success of Chinese academic staff and the local universities where they work. Extant literature has demonstrated that workplace interpersonal relationships such as leader-member exchange and team-member exchange are positively associated with individual’s work behaviours, such as knowledge sharing and innovative work behaviour. However, there is a scant literature on the impact of workplace guanxi upon the two workplace behaviours. Using conservation of resource theory and social exchange theory, this research conceptualised a structural model to study the impact of workplace guanxi upon knowledge sharing and innovative work behaviour. A positivist approach with cross-sectional design and structural equation modelling was adopted to test the conceptualised model. Data were extracted from 479 academic staff of seven local universities in Guangdong Province of China, through selfreport questionnaire. A positive relationship was found between coworker guanxi and knowledge sharing. In contrast, no relationship was found between supervisor-subordinate guanxi and knowledge sharing. The relationship between coworker guanxi and knowledge sharing was fully mediated by teammember exchange and job satisfaction. In terms of innovative work behaviour, both supervisorsubordinate guanxi and coworker guanxi displayed a positive relationship with innovative work behaviour. Coworker guanxi showed a stronger relationship with innovative work behaviour than supervisor-subordinate guanxi did. The relationship between supervisorsubordinate guanxi and innovative work behaviour was direct. The relationship between coworker guanxi and innovative work behaviour was indirect, with full mediation of teammember exchange, job satisfaction and knowledge sharing. This thesis contributes to the literature on explaining the role of workplace guanxi, including supervisor-subordinate guanxi and coworker guanxi on knowledge sharing and innovative work behaviour. The study also demonstrates to higher education institute managers that the cultivation of academic staff’s workplace guanxi, and particularly their guanxi with peer academics, promotes academic staff’s displays of knowledge sharing and innovative work behaviour which are beneficial at both individual and organisational levels within the higher education context.

Implementing inclusion : classroom journeys
- Authors: Elvey, Moya
- Date: 2020
- Type: Text , Thesis , PhD
- Full Text:
- Description: This study interrogates the professional experiences, attitudes and pedagogical choices of eight classroom teachers in regular schools and inquires into their impact on the development of inclusive teaching practices. Approached from the perspective of an experienced teaching practitioner, the study responds to the call for an increased focus on the role of classroom teachers in implementing inclusion in schools. The study is underpinned by a theoretical stance that promotes the value of inclusive education through a human rights, access and equity framework. It advocates for the importance of overcoming the discriminatory practices that marginalise some students. Consistent with a qualitative, ethnographic methodology, observations and interviews with practicing teachers provide insights into the factors that encourage, and sometimes discourage, the enactment of inclusive pedagogies. The literature on inclusive education provides guidance throughout the data collection and analysis process. This includes frameworks designed by other researchers that outline and define inclusive teaching strategies. The study exposes the pivotal role that ongoing teacher professional learning, along with strategic guidance and support from colleagues and school leaders, plays in enhancing teacher capacity and positive attitudes towards student diversity. It also uncovers evidence that when medical reports and pressure from ‘others’ such as health professionals, encourage teachers to focus on student ‘deficits’ and ‘problems’, they are more likely to seek out and adopt strategies that marginalise and set some students apart from their peers. A fundamental finding of this study is that when teachers and their school leaders focus on developing understanding about ‘effective’ pedagogies - on quality education for all - responsive, inclusive, student-centred teaching approaches often become embedded in their everyday classroom practice.
