Spiritual Art : evoking the numinous using a 3D computer game engine
- Authors: Nelson, Christopher
- Date: 2007
- Type: Text , Thesis , Masters
- Full Text:
- Description: The Seven Valleys is an interactive 3D installation based artwork inspired by mystical writings of the Bahá'í Faith. Created as a modification of the firstperson shooter Unreal Tournament 2003 (Epic, 2003) it subverts the original paradigm of the game to create an experience of the numinous, which in spirit, is diametrically opposed to the original intent of the gameplay design. This artwork presents an exploration of, and allusion to, the often subtle and illusive concepts found in the sacred treatise The Seven Valleys (Bahá'u'lláh, 1991) in which the user engages in an experiential journey through the work. The user is faced with conditions and situations that provide motivation to question, explore and attempt to fathom the abstract sense of the numinous. Each of The Seven Valleys contains its own individual mysteries while at the same time contributing its part to the telling of a collective story.

The presence and role of Thiamine and Riboflavin in the malting and brewing industries
- Authors: Hucker, Barry
- Date: 2013
- Type: Text , Thesis , PhD
- Full Text:
- Description: Thiamine and riboflavin vitamers are present in a wide range of foods including beer. They play critical roles in a variety of enzymatic complexes and can promote and maintain metabolism. Currently, the presence and role of these vitamers in the malting and brewing industry has not been widely explored. This research has investigated the effects of various malting and brewing processes on the final thiamine and riboflavin vitamer content of finished beer. In order to achieve this, a highly accurate and reproducible HPLC (spike recovery > 95 %; RSD < 5.0 %) method was developed that allowed the separation of thiamine diphosphate (TDP), thiamine monophosphate (TMP), thiamine, riboflavin 5-phosphate (FMN) and riboflavin in various sample matrices. This method was utilised to determine the vitamer content of various cereals and malts and it was found that malting vastly alters the thiamine content of malted barley, while it has minimal effect on riboflavin content. When malted barley is roasted, all vitamers are rapidly degraded. The mashing process releases the various vitamers into a solution and this release is dependent on temperature and enzymatic activity, while wort boiling significantly reduces the vitamer content of the wort. During fermentation, the thiamine content of wort is quickly utilised within the first six hours of standard fermentations and the uptake of this vitamin is not affected by increases in wort gravity. Meanwhile riboflavin is only poorly utilised during these fermentations. Post-fermentative additives, such as the addition of tannic acid and potassium metabisulphite, negatively affect the vitamin content of the final product while phosphorylated forms of these vitamins are greatly affected by the addition of many post-fermentative processing aids/additives. The presence of both thiamine and riboflavin can enhance the spoilage of beer by known brewery spoilage organisms, and the incorrect storage of bottle-conditioned beer can negatively affect the vitamin and organoleptic properties of the final product. These various steps involved in the production of beer greatly affect the final vitamin content, and this knowledge helps to explain the large variation in the thiamine and riboflavin vitamer content of a survey of 204 commercially available beers. This survey concluded that despite the large variations within particular styles of beer, lagers contain the least amount of thiamine compared to ales, stout/porters and wheat beers. However the average riboflavin content of the tested beers was statistically similar (p = 0.608) across all of the styles. This is due to the limited utilisation of this vitamin during fermentations.

Video-based training to improve decision-making performance of Australian football umpires

- Full Text:
- Description: Highly refined perceptual and decision-making skills are fundamental to the umpiring process in all sports although there has been little applied research which considers ways to improve umpires‟ perceptual and decision-making skills. Contemporary research has shown that video-based decision-making tests reliably separate highly skilled Australian football umpires from their lesser skilled counterparts. To date however, no studies have considered whether video-based protocols can be used as a training tool to enhance perceptual-cognitive learning for Australian football umpires. Consequently, in this dissertation, three interconnected studies were undertaken to develop and evaluate the effectiveness of a video-based training program to improve Australian football umpires‟ decision-making. Video-based methods of assessment have been commonly used to evaluate perceptual-cognitive performance of sports athletes and officials however, a major limitation of these studies is that they have not indicated whether their decision-making test had good reliability and/or validity. Study 1 of this PhD project sought to address this issue, by developing a valid and reliable video-based testing tool to monitor Australian football umpires‟ decision-making performance. The video-based decision-making test was developed from a pool of 156 video-based decision-making situations that were extracted from 23 Australian Football League games. The individual video-clips presented between 6-15 seconds of game play and all audio information was removed to ensure this did not influence participant responses. Face, content and construct validity were demonstrated, which indicated that the testing instrument was a representative measure of decision-making skill in Australian football umpires. The reliability study also provided evidence that 48 clips consistently measured decision-making skill over a two week time period. This investigation provided evidence of a reliable and valid decision-making test which can be used (pre and post) to detect improvements in decision-making following the implementation of a video-based intervention (Study 2). Study 2 investigated whether a 12-week video-based training intervention improved umpire decision-making. Metropolitan and regional Victorian Division One Australian football umpires were assigned to an intervention and control group. The intervention group completed one 20-minute video-based decision-making session per week, which presented between 60 and 225 decision-making situations. In total, 1040 different decision-making scenarios were presented over the duration of the program. In contrast to previous video-based training, the current investigation provided no explicit instruction or feedback. The control group only completed the pre and post decision-making tests. Decision-making performance of the intervention group significantly improved over time (p < 0.01), however no significant differences were observed in the control group (p = 0.94). The significant improvement of the intervention group mirrors the findings of other perceptual-cognitive research however, this study extended previous work by incorporating a greater number of decision-making trials and a discovery learning style. Findings indicated that decision-making skills can be improved without explicit instruction and in game experience. In addition, when separated according to umpire experience, participation in the video-based training program assisted less experienced umpires achieve the same decision-making standard on the video-based retention test as experienced umpires who did not complete any decision-making training (p = 0.85). Furthermore, decision-making performance of experienced umpires also showed significant improvement following participation in the video-based program (p = 0.02). Study 3 implemented a case study approach to investigate whether decision-making skills trained via video-based methods transferred to in-game performance. In-game performance of three participants from Study 2 (intervention group) were monitored (video-recoded and coded) during the Australian football season. In addition, qualitative methods were used to provide an understanding of the cognitive decision-making process of the three umpires. During the five monitored games each participant wore a voice recorder and were asked to „think out loud‟, providing a verbal report of their in-game decision-making process. Following the assessment of all five games, semi-structured interviews were conducted to provide further understanding of cognitive processes associated with each umpires‟ decision-making. Findings identified six themes that related to the in-game decision-making process (e.g., decision evaluation, player intention during game-play) and in-game umpire performance (e.g., anticipation, game-play instructions, player education, knowledge of game-play). Results supported the notion of skill transfer between video-based training and in-game decision-making performance, with all three participants improving their in-game decision-making performance from the first two games to the last two games analysed. This study provides initial evidence that video-based decision-making training can enhance in-game decision-making performance. Therefore, confirming that there is potential for skills developed through video-based training to transfer to in-game decision-making performance. As this was the first study to develop and evaluate the effectiveness of a video-based training program to improve Australian football umpires‟ decision-making, this PhD makes a significant and meaningful contribution to empirical knowledge. This study provides insight into the need for valid and reliable decision-making tests, and consideration of these constructs in future research will ensure a comprehensive approach to investigate the potential transfer of decision-making skills from video-based training programs to in-game performance. From a practical perspective, the findings from this study highlight the value of video-based decision-making activities to accelerate the decision-making performance of umpires without the need for extensive time commitment and/or in-game experience. This has important implications for the development of future Australian football umpires, particularly as the current video-based program can be modified and/ or used in current umpire training without the need for large time investment by umpire coaches. Furthermore, positive transfer from video-based training to in-game performance was evident, thus, confirming the potential for video-based training to improve in-game performance. Whilst further research using high quality research designs is required, this dissertation serves to guide further video-based training research across multiple decision-making domains in sport (i.e., umpires/referees, players).

A conceptual model of physical performance in Australian Football
- Authors: Mooney, Mitchell
- Date: 2013
- Type: Text , Thesis , PhD
- Full Text:
- Description: Objective: The objective of this project was to identify the relative influence of valid physical parameters to elite Australian Football performance. Methods: Data was collected on match performance variables (i.e. coaches’ votes, number of ball disposals, champion data rank), match exercise intensity measures (m∙min-1, m∙min-1 above and below 15 km∙h-1 and Load™∙min-1) and physical capacities (yo-yo intermittent recovery test level 2, maximum oxygen uptake, running economy, relative aerobic intensity, maximal aerobic speed and maximal accumulated oxygen deficit) on elite and recreational Australian footballers. These variables were modelled to determine the logical sequence and relative importance towards match performance. Results: The results indicate a sequential physical path to Australian Football performance. The yo-yo intermittent recovery test (level 2) performance influenced match exercise intensity (m∙min-1 >15 km∙h-1& Load™∙min-1) which in turn, affected Australian Football performance (number of ball disposals and coaches’ votes). This sequence was altered by experience, playing position and neuromuscular fatigue. The number of interchange rotations also influenced match exercise intensity throughout the match. Furthermore, the yo-yo intermittent recovery test (level 2) was found to be determined by a complex interaction of physical capacities. However, yo-yo intermittent recovery (level 2) performance was most influenced by maximum oxygen uptake, relative aerobic intensity and maximum aerobic speed. Conclusion: This dissertation showed Australian Football performance is a complex and dynamic system influenced by many variables interacting with each other in a sequential path. Sports scientists and coaches may utilise this information as a framework to evaluate Australian Football performance matches.

The influence of glycerol hyperhydration on run performance within an Olympic distance triathlon

- Date: 2004
- Type: Text , Thesis , Masters
- Full Text:
- Description: This study was designed to determine the impact of glycerol hyperhydration, compared with a placebo hyperhydration, on the run performance during an Olympic distance triathlon. Ten competitive triathletes (mean peak oxygen consumption, VO2 peak = 65.5 ± 5.5 ml.kg.-1min-1) undertook two simulated Olympic Distance Triathlons in 31° C and 61% relative humidity. The trials were split into two work phases: a fixed workload phase comprising a 18-20 min swim and a 60 min cycle and, a self regulated time trial run over 10 kilometres conducted on a treadmill. One hundred and fifty min prior each trial, either a glycerol solution (1 g.kg.-1 body mass (BM) in a 4% carbohydrate – electrolyte drink) or a placebo of equal volume of the 4% carbohydrate-electrolyte solution was ingested over one hour. The total fluid intake in each trial was 23 ml.kg.-1 BM. A randomised, double blind, cross over design was used. Due to either 1) the arduous nature of the trials 2) the side effects associated with the ingestion of glycerol 3) or the combination of the two aforementioned reasons, only five of the 10 subjects completed the final 10 km self regulated time trial for both treatments. Only the data obtained from these five subjects were reported in this study. Glycerol ingestion expanded body water over the placebo by 154 ml (26%). At 60 and 90 min after the start of drinking, urine output was significantly higher with glycerol than placebo treatment (216.4, 366.4 ml vs 81.0, 242.0 ml, respectively) but significantly higher at 120 min in the placebo (421.6 ml vs 131.2 ml). There were no significant differences in heart rate and rectal temperature during the swim and cycle phases. However, there were significant increases in heart rate (at 5, 10, 15, 25 and 30 min) and rectal temperature (at 5, 20 and 30 min) during the 10 km run in the glycerol trial. The mean 10 km run time for the placebo trial was 40 min 21 sec (± 2.9 min) while the glycerol trial was 39 min 22 sec (± 2.0 min). The mean difference of 2.1% in finishing time between trials was not significant. Three of the five subjects in the glycerol trial improved their 10 km time by 7.0, 2.4 and 2.7%, respectively. The finishing time for one subject did not change for both trials while another subject had deteriorated by 2.3% in the glycerol trial. In the glycerol treatment, five subjects complained of bloating and nausea while only one subject complained of feeling unwell in the placebo treatment. Data from this study have shown that glycerol hyperhydration did not significantly improve performance while plasma volume expansion and subsequent lower rectal temperature and lower heart rates were not evident. The exact mechanisms of how glycerol hyperhydration can improve performance warrant further investigation.

A neural network approach for predicting the direction of the Australian stock market index

- Type: Text , Thesis , Masters
- Full Text:
- Description: This research investigated the feasibility and capability of neural network-based approaches for predicting the direction of the Australian Stock market index (the target market). It includes several aspects: univariate feature selection from the historical time series of the target market, inter-market analysis for finding the most relevant influential markets, investigations of the effect of time cycles on the target market and the discovery of the optimal neural network architectures. Previous research on US stock markets and other international markets have shown that the neural network approach is one of most powerful techniques for predicting stock market behaviour. Neural networks are capable of capturing the non-linear stochastic and chaotic patterns in the stock market time series data. This study discovered that the relative return series of the Open, High, Low and Close prices of the target market, show 6-day cycles during the studied period of about 14 years. Multi-layer feedforward neural networks trained with a backpropagation algorithm were used for the experiments. Two major testing methods: testing with randomly selected test data and forward testing, were examined and compared. The best neural network developed in this study has achieved 87%, 81% 83% and 81% accuracy respectively in predicting the next-day direction of the relative return of the Open, High, Low and Close prices of the target market. The architecture of this network consists of 33 input features, one hidden layer with 3 neurons and 4 output neurons. The best input features set includes the relative returns from 1 to 6 days in the past of the Open, High, Low and Close prices of the target market, the day of the week, and the previous day’s relative return of the Close prices of the US S&P 500 Index, US Dow Jones Industrial Average Index, US Gold/Silver Index, and the US Oil Index.

- Description: This research investigated the feasibility and capability of neural network-based approaches for predicting the direction of the Australian Stock market index (the target market). It includes several aspects: univariate feature selection from the historical time series of the target market, inter-market analysis for finding the most relevant influential markets, investigations of the effect of time cycles on the target market and the discovery of the optimal neural network architectures. Previous research on US stock markets and other international markets have shown that the neural network approach is one of most powerful techniques for predicting stock market behaviour. Neural networks are capable of capturing the non-linear stochastic and chaotic patterns in the stock market time series data. This study discovered that the relative return series of the Open, High, Low and Close prices of the target market, show 6-day cycles during the studied period of about 14 years. Multi-layer feedforward neural networks trained with a backpropagation algorithm were used for the experiments. Two major testing methods: testing with randomly selected test data and forward testing, were examined and compared. The best neural network developed in this study has achieved 87%, 81% 83% and 81% accuracy respectively in predicting the next-day direction of the relative return of the Open, High, Low and Close prices of the target market. The architecture of this network consists of 33 input features, one hidden layer with 3 neurons and 4 output neurons. The best input features set includes the relative returns from 1 to 6 days in the past of the Open, High, Low and Close prices of the target market, the day of the week, and the previous day’s relative return of the Close prices of the US S&P 500 Index, US Dow Jones Industrial Average Index, US Gold/Silver Index, and the US Oil Index.

- Description: This research is the incorporation and melding of classical and Bayesian statistical techniques into an iterative methodology aimed at reducing two major confounding issues in Adverse Drug Reactions (ADRs), confounding by association (drug therapy) and confounding by indication (medical condition) to assist in the detection of signals. [...] This study highlights the ability of the STATFILE algorithm to detect drugs that are potential signals. More importantly, it also flags those drugs that are considered to be bystander drugs or noise, consequently reducing confounding by association. [...] This work highlights the significance and viability of an automated signal detection system and its practical application for the Australian spontaneous reporting of ADRs scene and potentially the international scene.

Spiritual awareness of professional nurses in the western region of Victoria: Investigation of a significant component of holistic heath care
- Authors: Lea, Dorothy
- Date: 2005
- Type: Text , Thesis , Masters
- Full Text:
- Description: A desire to more fully understand the impact of altered states of spiritual health on the general health of patients has been a focus of recent research activity. Studies have explored the meaning of spirituality held by patients and nurses, the spiritual needs of patients, and methods of providing spiritual care in nursing. However, few studies have investigated nurses’ own spiritual health and the significance this may have on the provision of holistic nursing care. The aim of this study, therefore, was to inform nursing regarding the spiritual health of nurses and the influence that nurses’ own spiritual health has on their ability to provide holistic nursing care to their patients. The study was conducted in two phases using both quantitative and qualitative methodologies. Phase one consisted of a survey of Division 1 nurses currently employed in the Grampians region of Victoria to describe key dimensions of their spiritual health. This survey provided biographical data and, through the use of the “Shalom Measure of Spiritual Health”, discovered the ideal of spiritual health held by nurses as well as the nurses’ perception of patient needs pertaining to the achievement of spiritual health. Phase two utilised Naturalistic Inquiry to further explore the meaning of spirituality and spiritual health held by nurses, and the methods of achieving these for nurses and patients. The findings revealed that although nurses perceive the spiritual dimension of patient care to be important, they feel ill-equipped to provide this aspect of care. In addition, the major support for nurses, who themselves experience spiritual distress whilst at work, comes from colleagues. Further, prevailing health care systems in place do not always lend themselves to holistic approaches to care. This study identifies the need for nurse education to redress the clearly inadequate preparation nurses are given for this aspect of their role. Health care policy-makers and administrators also have a responsibility to consider all dimensions of care when designing and implementing health care guidelines and systems.

Secret suburbia : An anthology of concepts relating to house and home

- Type: Text , Thesis , Masters
- Full Text: false
- Description: The aim of this research project has been to merge components of ideas relating to House and Home that have been formed by the inherently sensitive autobiographical nature of my own experience whilst growing up in a suburban environment. Naturally, these symbols or metaphors of the mundane reveal much more than what superficial impressions allow. They invite the viewer into an inner world of dream /memory and hypothesis that hopefully invokes within the viewer a desire to reach beyond their own perceptions of the everyday, and to re-examine the source of their own identity, thereby bringing some new emphasis to their own significant journey.

The Body as Fiction / Fiction as a Way of Thinking: On Writing A Short (Personal) History of the Bra and its Contents
- Authors: Spencer, Beth
- Date: 2006
- Type: Text , Thesis , PhD
- Full Text:
- Description: This thesis uses fiction as a research technology for investigating and thinking about issues to do with bodies and knowledge at the cusp of the 20th and 21st centuries. It includes sample material from a novel in progress -- A Short (Personal) History of the Bra and its Contents -- to illustrate some of the unique outcomes of this approach to exploring cultural history and writing cultural criticism. One of the advantages of fiction is that it allows me to create a discursive field in which it is possible for the very wide range of issues raised by my topic to coexist, work off each other and cross-fertilise. These include ideas regarding gender, sexuality, nurture and subjectivity; issues to do with the implants controversy, the cancer industry and the corporatisation of medicine (and hence various current debates within science and medicine); as well as movements in fashion history and popular culture -- all of which contribute to making up the datasphere in which and through which we continually reproduce ourselves as subjects.

- Description: "A natural process in examining properties of Banach spaces is to see if a Banach space can be decomposed into simpler Banach spaces; in other words, to see if a Banach space has complemented subspaces. This thesis concentrates on three main aspects of this problem: norm of projections of a Banach space onto its finite dimensional subspaces; a class of Banach spaces, each of which has a large number of infinite dimensional complemented subspaces; and methods of finding Banach spaces which have uncomplemented subspaces, where the subspaces and the quotient spaces are chosen as well-known classical sequence spaces (finding non-trivial twisted sums)." --Abstract.

Structural properties and labeling of graphs

- Type: Text , Thesis , PhD
- Full Text:
- Description: The complexity in building massive scale parallel processing systems has re- sulted in a growing interest in the study of interconnection networks design. Network design affects the performance, cost, scalability, and availability of parallel computers. Therefore, discovering a good structure of the network is one of the basic issues. From modeling point of view, the structure of networks can be naturally stud- ied in terms of graph theory. Several common desirable features of networks, such as large number of processing elements, good throughput, short data com- munication delay, modularity, good fault tolerance and diameter vulnerability correspond to properties of the underlying graphs of networks, including large number of vertices, small diameter, high connectivity and overall balance (or regularity) of the graph or digraph. The first part of this thesis deals with the issue of interconnection networks ad- dressing system. From graph theory point of view, this issue is mainly related to a graph labeling. We investigate a special family of graph labeling, namely antimagic labeling of a class of disconnected graphs. We present new results in super (a; d)-edge antimagic total labeling for disjoint union of multiple copies of special families of graphs. The second part of this thesis deals with the issue of regularity of digraphs with the number of vertices close to the upper bound, called the Moore bound, which is unobtainable for most values of out-degree and diameter. Regularity of the underlying graph of a network is often considered to be essential since the flow of messages and exchange of data between processing elements will be on average faster if there is a similar number of interconnections coming in and going out of each processing element. This means that the in-degree and out-degree of each processing element must be the same or almost the same. Our new results show that digraphs of order two less than Moore bound are either diregular or almost diregular.

The Sexual beliefs, attitudes and script of men convicted of sexual offences against children : An empirical investigation
- Authors: Owen, Karen
- Date: 2007
- Type: Text , Thesis , PhD
- Full Text:
- Description: Community concern about sexual offending places continued pressure on correctional services to refine treatment and reduce re-offending. While cognitive processes have been identified as a key element in the development and maintenance of sexual offending, more research on the precise nature of these processes is required. The current study, based on Ward and Siegert’s Pathways Model, involved 100 male offenders of various types: 25 intra – familial sex offenders against children, 25 extra-familial sex offenders against children, 25 sex offenders who chose adult victims, and 25 convicted of non-sexual offences. There was also a control group of 25 non-offenders. The quantitative data, derived from a series of questionnaires concerning childhood and sexual experiences, provided evidence that the two types of child sex offender differed from the other groups with respect to their expectations of sexual behaviour among children, their experience of sexual abuse and neglect as children themselves, and, paradoxically, their current high self-esteem. In addition, scripts relating to hypothetical consenting adult sexual relations and sexual contact with a child were collected from the 50 sex offenders against children. The script content suggested that, compared with intra - familial offenders, extra-familial offenders had notably unrealistic, naïve and romanticised scripts for adult relationships and more sophisticated scripts for offences against children. The latter suggested that scripts might serve as a mediating function in offending behaviour and that offenders acquired a degree of task domain expertise. Despite some inherent problems undertaking research with the sex-offender population, the findings confirmed that sex-offenders do not constitute a homogenous group and that the pathways model offers a unique perspective on how males become and develop their capacity as sex-offenders, how they sustain a positive view of themselves, and how they continue to commit offences. Finally, the model was considered in terms of its capacity to suggest ways to better target treatment efforts to specific groups of sexual offenders to further reduce their rate of recidivism

Distribution of arsenic and heavy metals in soils and surface waters in Central Victoria (Ballarat, Creswick and Maldon)
- Authors: Sultan, Khawar
- Date: 2006
- Type: Text , Thesis , PhD
- Full Text:
- Description: "Three sampling campaigns were conducted in the Ballarat, Creswick and Maldon areas. The sampling area is part of the Golden Triangle region where significant gold-mining activities took place from the 1850s to the present day. [...] Locations were chosen to evaluate arsenic distribution in soils, surface waters and plants in different environments. Easy access to sampling locations allowed detailed scientific sampling, especially in the seasonality study. The different range of environments such as agricultural, state forest, mining, urban and rural provided an opportunity to compare the concentrations of arsenic and other elements in the study area. The study of the three selected areas combined provided further understanding of possible exposure and pathways through which arsenic can get into the food chain. "The objective of the study is to measure levels of heavy metals/metalloids in soils, water and plants in various environments, identify whether the heavy metals/metalloids are mobile and bioavailable and understand the importance of clays and oxide complexes in the fixation of metals."
