Learning a trade in New Zealand : On and off the job learning in engineering trades

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

Description: This thesis specifically examines the relationship between professional business advisor (PBA) knowledge and the knowledge transmission actions undertaken by such advisors when addressing the knowledge requirements of businesses, specifically Regional Australian small businesses. The thesis adopts a qualitative research approach to explore perceptions of individuals who provide advisory services to small businesses, within the context of Regional Australia. The analysis undertaken is a practical application of the critical realist research paradigm to explain how human agency, social structures, and mechanisms interact in the process of creating a knowledge transmission event by PBAs. The conceptual framework developed in this thesis brings together key concepts from scholarly research disciplines of knowledge management, information management, communications, services marketing and business advice. The conceptual framework reflects the research aims and provides the basis for the research methodology. The framework is of a unique critical realist research design that allows the study to progress through sequential world views. Each world view allows the continual broadening of the reality being studied, enabling more focused answers to the research questions posed. This study focuses on PBAs who service small businesses operating in four inner regional and two outer regional locations within the State of Victoria. Over the six regions, a total of 29 face-to-face interviews were conducted, along with one focus group in each region. The findings from this database, using the conceptual framework as a guide, identified a complex, heterogeneous, open environment in which PBA knowledge transmission occurs. This research process recognises PBAs as social structures with causal powers whose knowledge stock is the primary mechanism through which these powers are exercised to generate a knowledge transmission event. A significant conclusion emerges that PBA tacit (and not explicit) knowledge is a conditional mechanism which gate-keeps whether the PBA knowledge transmission event is enacted.

Site, substance and sensation

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

Bitcoin : users’ characteristics, motivations and investment behaviours

- Carter, Corey

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

Description: This thesis sought to reveal the physical and kinematic determinants of pace bowling performance. After drawing on these determinants, a secondary aim was to investigate whether pace bowling performance could be enhanced with chronic resistance training and warm-up strategies. However, before the physical and kinematic determinants of pace bowling performance could be identified, and the effects of two training interventions and warm-ups on pace bowling performance, a new pace bowling test was created, and the test-retest reliability of its performance and kinematic measures were evaluated. Knowledge of a variables’ test-retest reliability is important for interpreting the validity of correlations, but also for the determination of a meaningful change following a training intervention. Only one published study to date has explored the test-retest reliability of a pace bowling assessment, and this test only measured bowling accuracy (1). Previous research has not comprehensively examined the relationships between physical qualities and pace bowling performance. Several important physical qualities (e.g., power, speed-acceleration, flexibility, repeat-sprint ability) have been excluded in correlational research, which may be crucial for optimal pace bowling performance. Furthermore, there is only one published training intervention study on pace bowling research (2). Consequently there is scant evidence for coaches to design training programs proven to enhance pace bowling performance. Baseball pitching studies have trialled the effects of heavy-ball throwing in the warm-up on subsequent throwing velocity and accuracy, but this approach has not been studied in cricket pace bowling, especially after several weeks of training. Therefore, four studies were conducted in this PhD project to address these deficiencies in the literature. The purpose of Study 1 (Chapter 3) was to ascertain the test-retest reliability of bowling performance measures (i.e., bowling speed, bowling accuracy, consistency of bowling speed, and consistency of bowling accuracy) and selected bowling kinematics (i.e., approach speed, step length, step-length phase duration, power phase duration, and knee extension angle at front-foot contact and at ball release) in a novel eight-over test, and for the first four overs of this test. The intraclass correlation coefficient (ICC), standard error of measurement (SEM), and coefficient of variation (CV) were used as measures of test-retest reliability (3). Following a three week familiarisation period of bowling, 13 participants completed a novel eight-over bowling test on two separate days with 4–7 days apart. The most reliable performance measures in the bowling test were peak bowling speed (ICC = 0.948–0.975, CV = 1.3–1.9%) and mean bowling speed (ICC = 0.981–0.987, CV = 1.0–1.3%). Perceived effort was partially reliable (ICC = 0.650– 0.659, CV = 3.8–3.9%). However, mean bowling accuracy (ICC = 0.491–0.685, CV = 12.5–16.8%) and consistency of bowling accuracy failed to meet the pre-set standard for acceptable reliability (ICC = 0.434–0.454, CV = 15.3–19.3%). All bowling kinematic variables except approach speed exhibited acceptable reliability (i.e., ICC > 0.8, CV < 10%). The first four overs of the bowling test exhibited slightly poorer test-retest reliability for all measures, compared to the entire eight-over test. There were no systematic biases (i.e., p > 0.05) detected with all variables between bowling tests, indicating there was no learning or fatigue effects. The smallest worthwhile change was established for all bowling performance and kinematic variables, by multiplying the SEM by 1.5 (4). It is recommended that the eight-over pace bowling test be used as a more comprehensive measure of consistency of bowling speed and consistency of bowling accuracy, as bowlers are more likely to be fatigued. However, if coaches seek to assess pace bowlers in shorter time, delimiting the test to the first four overs is recommended. Both versions of the pace bowling test are only capable of reliably measuring bowling performance outcomes such as peak and mean bowling speed, and perceived effort. The second study of this PhD project examined the relationships between selected physical qualities, bowling kinematics, and bowling performance measures. Another purpose of this novel study was to determine if delivery instructions (i.e., maximal-effort, match-intensity, slower-ball) influenced the strength of the relationships between physical qualities and bowling performance measures. Given that there were three delivery instructions in the bowling test, an objective of this study was to explore the relationship between bowling speed and bowling accuracy (i.e., speed-accuracy trade-off). Thirty-one participants completed an eight-over bowling test in the first session, and a series of physical tests, spread over two separate sessions. Each session was separated by four to seven days. Mean bowling speed (of all pooled deliveries) was significantly correlated to 1-RM pull-up strength (rs [24] = 0.55, p = 0.01) and 20-m sprint time (rs [30] = -0.37, p = 0.04), but the correlations marginally increased as delivery effort increased (i.e., maximal-effort ball). Greater hamstring flexibility was associated with a better consistency of bowling speed, but only for a match-intensity delivery (rs [29] = -0.49, p = 0.01). Repeat-sprint ability (i.e., percent decrement on 10 × 20-m sprints, on every 20 s) displayed a stronger correlation to consistency of bowling speed (rs [21] = -0.42, p = 0.06) than for mean bowling speed (rs [21] = 0.15, p = 0.53). Bench press strength was moderately related to bowling accuracy for a maximal-effort delivery (rs [26] = -0.42, p = 0.03), with weaker but non-significant (p > 0.05) correlations for match-intensity and slower-ball deliveries. Bowling accuracy was also significantly related to peak concentric countermovement jump power (rs [28] = -0.41, p = 0.03) and mean peak concentric countermovement jump power (rs [27] = -0.45, p = 0.02), with both physical qualities displaying stronger correlations as delivery effort increased. Greater reactive strength was negatively associated with mean bowling accuracy (rs [30] = 0.38, p = 0.04) and consistency of bowling accuracy (rs [30] = 0.43, p = 0.02) for maximal-effort deliveries only. Faster bowling speeds were correlated to a longer step length (rs [31] = 0.51, p < 0.01) and quicker power phase duration (rs [31] = -0.45, p = 0.01). A better consistency of bowling accuracy was associated with a faster approach speed (rs [31] = -0.36, p = 0.05) and greater knee flexion angle at ball release (rs [27] = -0.42, p = 0.03). No speedaccuracy trade-off was observed for the group (rs [31] = -0.28, p = 0.12), indicating that most bowlers could be instructed to train at maximal-effort without compromising bowling accuracy. Pull-up strength training and speed-acceleration training were chosen for the “evidence-based” training program (Study 3). Heavy-ball bowling was also considered as part of the evidence-based training program, as it is a specific form of training used previously, and because there was a shortage of significant relationships (p < 0.05) between physical qualities and bowling performance measures in Study 2. The third investigation of this PhD project compared the effects of an eight-week evidence-based training program or normal training program (not a control group) on pace bowling performance, approach speed, speed-acceleration, and pull-up strength. Participants were matched for bowling speed and then randomly split into two training groups, with six participants in each group. After an initial two-week familiarisation period of bowling training, sprint training, and pull-up training, participants completed two training sessions per week, and were tested before and after the training intervention. Testing comprised the four-over pace bowling test (Study 1), 20-m sprint test (Study 2), and 1-RM pull-up test (Study 2). In training, the volume of bowling and sprinting was constant between both groups; the only differences were that the evidence-based training group bowled with heavy balls (250 g and 300 g) as well as a regular ball (156 g), sprinted with a weighted-vest (15% and 20% body mass) and without a weighted-vest, and performed pull-up training. Participants were instructed to deliver each ball with maximal effort in training, as no speed-accuracy trade-off was observed for the sample in Study 2. The evidence-based training group bowled with poorer accuracy and consistency of accuracy, with only a small improvement in peak and mean bowling speed. Heavy-ball bowling may have had a negative transfer to regular-ball bowling. Although speculative, a longer evidence-based program may have significantly enhanced bowling speed. Coaches could use both training programs to develop performance but should be aware that bowling accuracy may suffer with the evidence-based program. The evidence-based training group displayed slower 20-m sprint times following training (0.08 ± 0.05 s). However, the normal training group was also slower (0.10 ± 0.09 s), indicating the potential for speed-acceleration improvement is compromised if speed training is performed immediately after bowling training; most likely due to residual fatigue. Consequently it is recommended that speed-acceleration training be conducted when bowlers are not fatigued, in a separate session, or at the beginning of a session. The evidence-based training group improved their 1-RM pull-up strength by 5.8 ± 6.8 kg (d = 0.68), compared to the normal training group of 0.2 ± 1.7 kg (d = 0.01). The difference between training groups is due to the fact that the normal training group were not prescribed pull-up training. As many participants could not complete the pull-up exercise due to insufficient strength, the dumbbell pullover may be a suitable alternative that is more specific to the motion of the bowling arm (i.e., extended arm). The fourth study of this PhD project explored the acute effects of a heavy-ball bowling warm-up on pace bowling performance, and determined if these acute effects could be enhanced or negated following an evidence-based training program. This study involved the same participants who completed the evidence-based training program in Study 3. These participants were required to perform two different bowling warm-ups (heavy-ball or regular-ball) in pre and post-test period, followed by the four-over pace bowling test (Study 1). In pre-test period, bowling accuracy was 8.8 ± 7.4 cm worse for the heavy-ball warm-up compared to the regular-ball warm-up (d = 1.19). In post-test period however, bowling accuracy was 5.5 ± 6.4 cm better in the heavy-ball warm-up compared to the regular-ball warm-up (d = -0.90). A similar trend was observed for consistency of bowling accuracy. These findings indicate that pace bowlers adapt to heavy-ball bowling, and bowl more accurately with a regular ball if they warm-up with a heavy ball first (but only after eight weeks of heavy-ball training). Coaches could employ a heavy-ball warm-up prior to training or a match, but only after eight weeks of evidence based training. It is hypothesised that a less biomechanically similar exercise to the pace bowling motion such as resisted push-ups / bench press throws could be more effective in eliciting potentiation by activating higher order motor units without negatively transferring to bowling performance. From the studies presented in this thesis, it is concluded that peak and mean bowling speed are the most reliable bowling performance measures, and all kinematic variables apart from approach speed possess excellent reliability. Furthermore, 1-RM pull-up strength and 20-m speed are significantly correlated to bowling speed. An evidence-based training program can develop peak and mean bowling speed, but the cost to bowling accuracy and consistency of bowling accuracy does not make this training program worthwhile in enhancing pace bowling performance. A heavy-ball warm-up impairs bowling accuracy and consistency of bowling accuracy compared to the regular-ball warm-up, but only prior to training with the heavier balls. Pace bowlers adapt to heavyball bowling after eight weeks of training, but must use the heavy balls in the warm-up to bowl more accurately with a regular ball, otherwise pace bowling performance is below optimal.

Description: Classification of objects based on inherent properties is a general problem area encountered in diverse fields of knowledge. In terms of text classification, the problem presented in this work is based on two particular criteria for documents as given below: • Informativeness of feature sets - A feature set would comprise of words in a document. Presence of words that can be used to characterize a document in a corpus (database) is the informativeness of a feature set. • Multilabelness - documents can have content dealing with diverse topics These criteria are not localized to documents only, but can be generalized to other areas as well with little adaptation. In this thesis, the classification problem that is being investigated involve datasets containing the prescence of smaller number of features associated with a larger number of classes. The acronym SFML (Shorter Featured & Multi-Labeled) has been used to denote these types of datasets. Further, SFML type datasets can be encountered in various walks of life, like Medicine, SMS Services, Text Classification to name a few. In this thesis, the performance of various existing classification algorithms were tested on SFML datasets and their results compared. Further, a new classification algorithm based on optimization is also proposed for these types of datasets. Applications to the Adverse Drug Reaction problem and phishing profiling problem have been considered here. Classification results show that the proposed algorithm performs better than existing classification algorithms as the number of features tend to decrease.

Description: This thesis examines the importance of memory, commemoration, heritage and militarism in relation to Ballarat’s Avenue of Honour and Arch of Victory. Inspired by Ken Inglis and other historians who have analysed war commemoration, the thesis argues that, led by the Lucas clothing company, Ballarat civic leaders and community members commemorated the war service and sacrifice of local soldiers, airmen, sailors and nurses by planting the 22-kilometre Avenue during 1917–19 and by constructing the prominent Arch in 1920. Although Ballarat voted against conscription in 1916 and 1917 and was a ‘divided’ society, the Avenue and Arch were able to unite members of the local community. From the 1920s, through memory and mythology during the civic maintenance of the Avenue and Arch, Australian community attitudes to war and peace were reflected, and a determined effort was made to remember the service and sacrifice of military personnel for all Australian wars. Discussion of the need for peace remained in the background until recent years. Important influences on the civic management were the collective memory of the so-called Lucas Girls, a group of former female employees of the Lucas clothing company, and of the members of the Arch of Victory/Avenue of Honour Committee. Increasingly, the embracing of the Anzac legend and an emphasis on loss and grief was reflected in the civic management. By 2017 the Avenue and Arch were in pristine condition and, through the Garden of the Grieving Mother, had transformed to symbolise the importance of remembering the sacrifices and grief of war and the need for peace. The project was based on documentary research and oral history, using an examination of newspaper and other documentary accounts from 1917–2017, a study of Arch of Victory/Avenue of Honour Committee papers and conservation management plans, research of relevant books and articles, landscape fieldwork and interviews with 26 people.

A philosophical analysis of the functions and operation of due process in accounting standard setting in Australia

- Mehta, Surinder

Authors: Mehta, Surinder
Date: 2016
Type: Text , Thesis , Masters
Full Text:
Description: The setting of accounting standards in the Australian context has undergone significant change over the past few decades because of both the introduction of international accounting standards and the outcomes of the Corporate Law Economic Reform Program (CLERP). One major thrust of these reforms was to widen the breadth of participation and to introduce new voices into the Australian accounting standard setting regime. Though there have been recent changes to Australian accounting standard setting arrangements, due process still remains as the underlying procedure for incorporating stakeholder participation. Standard setting resides within a socio-political and economic realm which lies between a capitalistic economic individualism premised upon self-interest and interest group preferences, and an idealistic paradigm of the public interest (common good). Both notions are espoused within modern civil society and present in the formulation of policy and regulation through participation. Recent times have seen the promulgation of accounting standards given over by delegated legislation to private sector interests who compete for desired outcomes and more recently this has been entrenched within the International Accounting Standards Board (IASB) which produces International Financial Reporting Standards (IFRS). This research presents a two-fold investigation of the due process which is applied when developing accounting standards in Australia. Firstly, this study questions whether such standards provide an adequate avenue for incorporating both appropriate attributes of participation and accountability in line with the historical understanding of due process as developed through common law. Secondly, this study questions whether such standards provide an appropriate vehicle for widening participation by introducing new voices into the Australian accounting standard setting process. On the former question, common law due process resonates within a paradigm that supports fair dealing and equity between individuals with themselves and with government. On the latter question, this research identifies low and declining stakeholder participation within the due process of accounting standard setting. This is accompanied by the declining interest of previous major participants. In examining the longitudinal participation trends of submitters to the accounting standard setting regime, this research contends that the due process finds itself embedded within the confines of a procedural construct to the detriment of accommodating natural justice through a more enlightened substantive approach. As such, when considered in light of its common law roots, it fails both to provide an adequate level of openness along with accommodating only a limited opportunity to participate, specifically when taking into account opinions and interests. The very construct of common law due process rests upon its ability both to subsume participation within the decision-making process, and for that participation to be substantive in the outcome of the process. That is, such participation gives meaning to the outcome. Instead the current due process as applied within the accounting standard setting environment resonates such participation through abolitionist type approaches. Here self-interested parties compete for advantages from property rights and private benefits in line with the more modern interpretation of the public interest. The approach taken in this thesis is to consider the due process from a philosophical perspective by assessing the questions of accountability and participation within the due process in terms of civil society, the public good, economic individualism, libertarianism, liberalism, and agency, rather than to embed the discussion within the expansive existing studies concerning due process in the accounting standard setting process. The conclusion from this perspective is that due process is clearly a process past its due date.

Teachers' emotional intelligence as a predisposition for discrimiation against students with severe emotional and behavioural disorders

- Metaxas, Melinda

Authors: Metaxas, Melinda
Date: 2018
Type: Text , Thesis , PhD
Full Text:
Description: Students with Emotional Behavioural Disorders (EBD) are among the most challenging students to teach. Personality Trait Theory predicts teachers’ level of Emotional Intelligence (EI) would affect their cognitive-affective-behavioural reactions towards students with EBDs, and influence level of academic achievement and difficult behaviour of these students. This research explores which teachers are more predisposed to discriminate against EBD students, and identifies the most ‘effective’, supportive EI teacher traits. Underlying psychological processes, such as genetic EI make-up of teachers, may prove to be most valuable in determining whether more practical strategies for dealing with students’ behaviour/emotions are effectively applied and successful. An Attribution Model framework helped assess teacher reactions towards students. Two hundred and sixty one teachers from 51 Victorian schools participated in the study by completing self-report questionnaires, including the Trait Emotional Intelligence Questionnaire. A quantitative survey methodology used vignettes, with each school contact person randomly giving 50/50 surveys to their teachers (depicting a student with either mild or severe EBD symptoms). Pathway analysis revealed that teachers with higher EI reported less stigmatising and punitive intentions and likely greater helping behaviours. A new EI Process Model of Stigmatisation was proposed to measure teacher reactions through an affective-cognitive-behavioural sequence, rather than a cognitive-affective-behavioural sequence. Teachers’ EI levels also related to their own levels of psychological distress and/or compassion stress, which influenced likely helping or punitive outcomes. Despite behavioural severity of EBD students, teachers higher in EI still indicate more supportive helping behaviours. Specifically-identified ‘ideal’ teacher EI traits should lead to greater helping and be psychologically beneficial to both students and teachers. These results assisted development of an assessment tool (ASET – Assessment Screen for Emotionally Intelligent Teachers), which lays a sound foundation for schools and others to profile or recruit teachers with best ‘qualities’ to effectively teach students EBD students.

The effects of playing Nintendo Wii on depression, sense of belonging, social support, and mood among Australian aged care residents : A pilot study

- Chesler, Jessica

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

James Curtis and spiritualism in Nineteenth-Century Ballarat

- Young, Gregory

Authors: Young, Gregory
Date: 2017
Type: Text , Thesis , PhD
Full Text:
Description: This thesis is about the origins, growth, and decline of spiritualism in nineteenth- century Ballarat. It gives special attention to Rustlings in the Golden City, the religious confessions of James Curtis, a notable Ballarat pioneer and the city’s most active and prominent spiritualist believer and evangelist. In Ballarat, spiritualism was commonly regarded as little more than entertaining humbug, usually derided by the press as delusive nonsense. Though clerics occasionally condemned it as heretical and dangerous, few people took spiritualist ideas and practice seriously. Even so, Ballarat had its small core of devout believers. For these, spiritualism provided a route to direct, intuitive, knowledge of the destiny of the spiritual self, comparable to gnostic liberating self-discovery. Rustlings in the Golden City stands as a classic statement of Victorian-era spiritualism and James Curtis has claim to be regarded as Australia’s greatest nineteenth-century spiritualist. While the commitment of many prominent Australian spiritualists of the period was compromised by credulity, bad faith, and self-interest, James Curtis was guileless and sincere. His writings open a window on a neglected area of nineteenth-century Australian social and religious history. The historiography of the thesis is realist and empiricist, with the predominant methodology critical text-analysis. Its chief source is contemporary newspapers and journals and the publications of spiritualists and their opponents and critics.

An un-natural history : paradox, wonder and The Glass Flowers

Type: Text , Thesis

Description: This research project concerns itself with the human desire for control, order and perfection through an investigation of our attempts to control nature. The museum case acts as a metaphor for this attempt to organise the natural world in a logical and systematised fashion. In my artwork I aim both to present and to challenge this imposition of order and control through my interpretation of the Glass Flower display at the Harvard Natural History Museum, formally known as the Ware Collection of Blaschka Glass Models of Plants. This examination of the Glass Flowers and their visual representation has been informed and challenged by an understanding of their paradoxical and enigmatic position between science and art, nature and culture. In my artwork this ambivalence about the Flowers as objects of scientific certainty, and about the museum as a site of control, is expressed as an increasing tension between representation and abstraction, the precise rendition of form and the visibility of the medium of oil paint. Together with the exegesis this project explores issues of museology and the nature of collected and displayed objects, particularly these Glass Flowers which were purpose-made for the museum. My visual work responds to the museum environment in ways which both embrace its aesthetic and question its attitudes to nature. In doing so, it reflects the paradoxical nature of the Flowers and the nature of seeing itself, creating a visual world in which ambiguities of scale, location and even subject undermine our certainty of what we see, creating a magical space out of the ordered world of the museum.

Enhancing service quality and reliability in intelligent traffic system

Full Text:
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.

Description: The construction industry in Botswana plays a crucial role in the economic development of the nation. While much research in this sector centres on the technical issues, especially the tender/procurement processes as they have evolved over the years, there is limited research on employment relations. This study investigates the lived experiences of employees in the Botswana construction industry in both domestic-owned and Chinese-owned companies and aims to capture „snapshots‟ of their perceptions of the causes and forms of conflict within that sector. Adopting a pragmatism research paradigm, this research employs a mixed methods research protocol to obtain quantitative and qualitative data from a sample of 632 employees. The overall results reveal that there are statistically significant differences between domestic- and Chinese-owned companies, with respect to how employees perceive income distribution, job security and managerial control as causes of conflict. The empirical results show that there is a positive relationship between employees‟ negative workplace perceptions and various forms of workplace deviant behaviours that employees use to retaliate in the event they perceive some form of unfairness, particularly in wages, job security or how managers/supervisors treat them. In domestic-owned companies there is a significant and positive association between disparity of income distribution and personal gain deviant behaviours such as theft as compared to other deviant activities against the production process including sabotage and production deviance; while in Chinese-owned companies there is a significant positive association between all forms of workplace inequities (income distribution, job security, managerial control) and all forms of conflict. This study contributes to the development of a more rigorous approach to the analysis of industrial relations conflicts in the construction industry in developing economies. This type of comparative research between domestic- and Chinese-owned companies could possibly be transferred to similar industries, such as in manufacturing and retail, where there are also a significant number of foreign-owned companies. This thesis concludes by discussing the various contributions made by this study to both academia and practitioners. It also details several recommendations for future research and for ensuring peaceful and productive employee-employer relationships in the workplace.
