- Description: This thesis addresses the gap that has existed in Ballarat’s historiography regarding the historical neglect and ignorance of Chinese family narratives and their life experiences. In doing so this thesis presents a longitudinal, three generational study of an immigrant Ballarat Chinese family from the early 1860s until the 1950s. It examines how members of each Tong Way generation strove to gain acceptance and establish an enduring sense of cultural belonging in a former regional, Victorian gold mining city. An ancestor, Liu Chou Hock, was a sojourner who arrived on the Haddon goldfield in 1862 and successfully worked a claim. Within three years, he returned to his village, Wang Tung, in Taishan, China. His experience was in sharp contrast to that of his son John Tong Way (Liu’ Zongwei) who permanently settled in Ballarat. The family strived to integrate against a background of migrant adjustment, ethnic discrimination and later a policy of assimilation. These factors represented a challenge for all Chinese who remained until the White Australia Policy was abandoned by the Whitlam Labor government in 1973. Unlike Caucasian immigrants, who could assimilate, whilst retaining certain features of their ethnic identification, the Chinese were culturally alienated and often excluded from everyday cultural life and practice. They represented a demographically significant ethnic minority. The thesis also compares the experiences of the Ballarat and Bendigo Chinese communities in order to examine the similarities and differences. In doing so, it analyses how they were able to establish a sense of belonging in their respective communities. The analysis of the Ballarat family’s experiences, combined with that of other Chinese descent families forms the basis of an extended case study. One that argues that adaptation was necessitated by their individual aspirations for acceptance, respectability and success.

A continuous flow elevator to lift ore vertically for deep mine haulage using a cable disc elevator
- Authors: Webb, Colin
- Date: 2020
- Type: Text , Thesis , PhD
- Full Text:
- Description: Vertical continuous ore haulage with elevators in mining for deep haulage is virtually non-existent. In this, research investigations concentrated on a cable disc elevator. The problem of using a cable disc elevator is the friction between the elevator fixed tube and the moving ore on the disc. This research establishes the friction forces existing as the elevator cable and discs are elevated up a stationary tube. Then the focus is to find a way to eliminate that friction. The method involved developing three test rigs: Test Rig 1 measures static friction with the ore placed on a disc in a tube mounted on load cells to measure the resistance with the ore on the disc lifted by a counterweight. This is relevant for an elevator that has stopped under load. Test Rig 2 measures the dynamic friction in an operational 5-inch elevator with the tube on the lifting side held stationary by load cells when the cable discs are lifting the ore. Test Rig 3 eliminates friction in the lifting tube by using a pipe conveyor that travels vertically at the same speed as the cable disc elevator to contain the ore on the cable disc elevator. The cable disc elevator does all the ore lifting. The research generated results for static and dynamic friction for gravel, granite and coal. Cable tension required for ore lift of 1000 metres and the maximum hoisting distance for some existing cables are calculated. Implications of this research are that the cable disc elevator has the potential to haul from depths greater than existing elevators, has a small footprint in a mine, and with some further development could eliminate the need for truck haulage in open cut and underground mining from the mine.

A good sheep run. Letters from New South Wales in Scottish newspapers between 1820 and 1850 with potential to influence decisions on emigration

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

- Description: There has been a great deal of research undertaken in the field of Human-Computer Interfaces (HCI), input devices, and output modalities in recent years. From touch-based and voice control input mechanisms such as those found on modern smart-devices to the use of touch-free input through video-stream/image analysis (including depth streams and skeletal mapping) and the inclusion of gaze tracking, head tracking, virtual reality and beyond - the availability and variety of these I/O (Input/Output) mechanisms has increased tremendously and progressed both into our living rooms and into our lives in general. With regard to modern desktop computers and videogame consoles, at present many of these technologies are at a relatively immature stage of development - their use often limited to simple adjuncts to the staple input mechanisms of mouse, keyboard, or joystick / joypad inputs. In effect, we have these new input devices - but we're not quite sure how best to use them yet; that is, where their various strengths and weaknesses lie, and how or if they can be used to conveniently and reliably drive or augment applications in our everyday lives. In addition, much of this technology is provided by proprietary hardware and software, providing limited options for customisation or adaptation to better meet the needs of specific users. Therefore, this project investigated the development of open source software solutions to address various aspects of innovative user I/O in a flexible manner. Towards this end, a number of original software applications have been developed which incorporate functionality aimed at enhancing the current state of the art in these areas and making that software freely available for use by any who may find it beneficial.

- 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.

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.

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.

- 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.

- 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.

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.

Fraud detection for online banking for scalable and distributed data
- Authors: Haq, Ikram

- Type: Text , Thesis , PhD
- 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.

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.

Internationalisation of higher education curriculum : a case study in Vietnam
- Authors: Luong, Thi Phuong
- Date: 2020
- Type: Text , Thesis , PhD
- Full Text: false
- Description: This thesis investigated how the process of internationalisation of the curriculum (IoC) was perceived as taking place at a non-western university, namely Foreign Trade University (FTU) in Vietnam, through the development and offering of a number of jointly run programs, labelled Foreign Undergraduate Programs (FUPs). Two specific programs were examined, both of which were developed in partnership with two western universities – Colorado State University (FTU-CSU program) and London Metropolitan University (FTU-LMET program). These programs provide a range of opportunities for Vietnamese university students to experience an education that aims to reflect an international and therefore ‘broader’ context. The relationship between globalisation and internationalisation is explored and linked with the development of curriculum in higher education and internationalisation trends and strategies. Internationalisation of the curriculum, which is one of the internationalisation strategies employed by educational institutions, is investigated in terms of its interrelationship with student learning, the disciplines and academics. Engeström’s (2001) third generation Activity Theory was used as the theoretical lens for analysis of the data, which was collected via a mainly qualitative case study. Two cohorts of participants provided data through 24 interviews (seven including a joint one with program leaders/course coordinators, and 17 with academics) and 34 surveys completed by academics. The interviews/survey investigated participants’ perceptions about internationalisation and particularly IoC in relation to the two programs. Part of the significance of this study lies in the use of a number of conceptual and theoretical frameworks to extend the current body of literature beyond the main context of western higher education. An innovation in this study was the evaluation of the level of curriculum internationalisation at FTU, which was conducted using the model of curriculum internationalisation proposed by Huang (2017). Findings suggested that program managers and course coordinators worked collaboratively with their western partners to provide programs that they perceived as worthwhile in meeting the needs of the institution and the Vietnamese government agenda for internationalisation. However, academics were not generally well informed about the broader goals relating to IoC and found it challenging to accommodate the expectations with limited resources and lack of appropriate training.

Investigating the configuration of a flight training device for visual flight rules navigation
- Authors: Harvey, William
- Date: 2020
- Type: Text , Thesis , PhD
- Full Text:
- Description: The acquisition of pilot navigational skills utilising visual landmarks is a crucial skill that is required as part of Visual Flight Rules navigation towards obtaining a Private Pilot License. Due to the high cost of pilot training simulators, industry has identified a need for research in efficient utilisation of low-end, low cost personal compute flight simulators to assist in developing pilot skills. Analysis of the effectiveness of the use of such personal computer simulators depend on proper configuration determined by measurable errors to define simulator fidelity. To date, research has shown that the configuration of these simulators appears to have been done in an ad-hoc fashion and not in a scientific fashion. Therefore, the problem that needed to be solved was how to effectively configure such simulators. This thesis research attempted to solve this problem and present the process for effectively configuring a personal computer simulator, or flight training device, capable of successful Visual Flight Rules navigation. The simulator was configurated utilising a process that followed an interpretation of the Design Science research method, and an error correction model to determine the errors in the simulator configuration. This was done by comparing two probability distributions to measure the maximum error variable distance in order to configure a simulator suitable for the acquisition of Visual Flight Rules navigation piloting skills required for obtaining a Private Pilot Licence in Australia. This error identification method was then used to indicate simulator configuration efficiency and fidelity in order to achieve a minimum suitable configuration and setup. Further application of the findings of this research could potentially lead to the configuration of different types of non-aviation simulators, in particular Part-Task-Trainers and other training devices, including Virtual Reality Augmented Reality devices utilising various types of platforms such as Windows, Apple, and Android.

Never afters : female friendship and collaboration in contemporary re-visioned fairy tales by women
- Authors: McDermott, Kirstyn
- Date: 2020
- Type: Text , Thesis , PhD
- Full Text:
- Description: Antagonism among girls and women in fairy tales has been the subject of much critical and popular discussion over recent decades. Significantly less attention, however, has been paid to the frequent absence of collaborative female relationships in traditional fairy tales and their contemporary retellings. Holding re-visioned fairy tales to be a type of feminist creative praxis, this thesis investigates how mutually beneficial relationships between female characters may be constructed within such narratives. “Never Afters” is a collection of six re-visions, written as sequels to well-known fairy tales from the Western European corpus. Situated within a genre that commonly isolates female characters or foregrounds female antagonism, each re-vision employs one (or more) of five key strategies that are used by contemporary authors to imagine collaborative female relationships within retold fairy tales: inversion, insertion/deletion, expansion, fusion, and extrapolation. The exegesis contextualises my creative work and assesses the strengths and limitations of each strategy by critically examining how they are used in contemporary fairy tales by authors including Emma Donoghue, Theodora Goss, Angela Slatter, Aimee Bender, and Kelly Link. I demonstrate that expansion, fusion, and extrapolation best allow authors to introduce new female characters and fresh feminist perspectives that move away from female exceptionalism and instead foreground female collaboration and friendship as potent sources of narrative power. The exegesis further argues that the cognitive sciences, and schema theories in particular, may offer insights as to why collaborative female relationships have received such scant representation. Using case studies of my own creative praxis, I explore the ways in which female isolation and acrimony are re-inscribed in contemporary work and recommend the adoption of new frameworks through which creative writers may critically and reflexively interrogate their tacit storytelling knowledge.

Positive attitude change to school - Narrative inquiry into adolescent students' lived experiences
- Authors: Wojtaszek, Sylwia
- Date: 2020
- Type: Text , Thesis , PhD
- Full Text:
- Description: This thesis reports on a qualitative research study that investigated adolescent students‟ experiences of positive attitude change to school. The literature review situates the research of students‟ attitude changes to school within the affective component of the multidimensional construct of student engagement and identifies this field and the phenomenon of positive attitude change to school as underresearched and under-theorised. Narrative inquiry methodology was applied in order to provide a detailed description of students‟ lived experiences and generate knowledge to fill the existing gap of how such an experience manifests itself. Eight students, who self-reported to have experienced positive attitude change to school, shared stories through in-depth semi-structured interviews of how the attitude change came about, who or what influenced it, and what meaning they attached to it in relation to its impact on their engagement and wellbeing. Students‟ attitudes to school are predominantly examined through quantitative research, whereas this study provided a unique and nuanced insight into attitude change based on the qualitative paradigm and a social constructionist view of the experience from the students‟ vantage point. Students‟ narrative accounts are compared and contrasted with each other to identify five resonant threads associated with the experience of positive attitude change to school. Data analysis suggests that positive attitude change to school has a significant impact on student engagement in learning and student wellbeing through its embodiment of perceived positive emotions associated with being at school. It consequently illustrates the relevance of broadening the understanding of such an experience to address the critical issue of disengagement in adolescent students. Key findings indicate that students develop a negative attitude to school when personal problems remain unresolved or have been insufficiently addressed within the school environment; no “helping hand” was there to assist these ambitious students who were struggling to engage in learning due to their experience of negative emotions at school. This research study has revealed that a negative attitude to school does not necessarily equate to a negative attitude to learning. Students‟ perception of the available support, both from the teachers and the services offered at school, is a critical factor in the transformation of their attitudes to school. Further, the students who participated in this study did not themselves feel that they were equipped with the required knowledge and skills to manage their personal problems effectively in order to maintain their engagement in learning. Only after having “hit rock bottom” and having sought help from outside the school environment were the students able to apply a different perspective to their circumstances that was associated with positive attitude change to school. From this research study it can be concluded that a student‟s positive attitude to school is a requirement for successful social and academic outcomes, and it is an educational goal in itself regarding the notion of developing lifelong learners. Personal problems and their impact on student engagement and wellbeing need to be acknowledged and catered for within the school environment. School support services must proactively extend a helping hand to students who have a negative attitude to school. Further, students need to develop selfefficacy regarding their personal wellbeing so that they become confident to act autonomously in solving their situations at school that are characterised by the difficult negative emotions that they are experiencing. Students‟ attitudes to school and the complexity of the multidimensional construct of student engagement need to be considered in the development of initiatives to address adolescent student disengagement and in the development of student wellbeing frameworks.

Random finite element method prediction and optimisation for open pit mine slope stability analysis
- Authors: Dyson, Ashley
- Date: 2020
- Type: Text , Thesis , PhD
- Full Text:
- Description: Inherent soil variability can have significant effects on the stability of open-pit mine slopes. In practice, the spatial variability of materials is not commonly considered as a routine component of slope stability analysis. The process of quantifying spatially variable parameters, as well as the modelling of their behaviour is often a complex undertaking. Currently, there are no large-scale commercial software packages containing in-built methods for modelling spatial variability within the Finite Element environment. Furthermore, conventional Limit Equilibrium Methods (LEM) incorporating spatial variability are unable to consider the stress/strain characteristics of these materials. The following research seeks to accurately model the slope mechanics of spatially variable soils, adopting The Random Finite Element Method (RFEM) developed by Griffiths and Fenton (2004) to determine slope failure mechanisms and safety factors. Techniques are developed to produce a set of optimised Random Finite Element Method simulations using the Monte Carlo Method. Additionally, random field analysis techniques are investigated to compare and categorise soil parameter fluctuation, providing a direct relationship between random field properties and slope failure surfaces. Optimisation and analysis techniques are implemented to examine the effects of cross-sectional geometries and input parameter distributions on failure mechanisms, safety factors and probabilities of failure. Cross-sectional RFEM analysis is performed in the Finite Element Method (FEM) software package Abaqus, with the techniques of this research demonstrated for a large open-pit brown coal mine located in the state of Victoria, Australia. The outcome of this research is a comprehensive procedure for optimised RFEM simulation and analysis.

Additionally, random field analysis techniques are investigated to compare and categorise soil parameter fluctuation, providing a direct relationship between random field properties and slope failure surfaces. Optimisation and analysis techniques are implemented to examine the effects of cross-sectional geometries and input parameter distributions on failure mechanisms, safety factors and probabilities of failure. Cross-sectional RFEM analysis is performed in the Finite Element Method (FEM) software package Abaqus, with the techniques of this research demonstrated for a large open-pit brown coal mine located in the state of Victoria, Australia. The outcome of this research is a comprehensive procedure for optimised RFEM simulation and analysis.
