Characterisation and investigation of serious thoracic injuries in passenger vehicle rollover crashes
Dr Tana Tan
Supervisor: Prof. Raphael Grzebieta
Passenger vehicle rollover crashes involving a single vehicle occur infrequently; however, when they do the vehicle occupants in these crashes are more likely to sustain serious and fatal injuries compared to other crash modes. The thorax is frequently seriously injured in rollover crashes. Ongoing efforts in the USA and Australia have sought to understand the characteristics and aetiology of these injuries. Despite these efforts, the characteristics and aetiology of thoracic injuries in rollover crashes are still not well understood. Four studies were performed and documented in this thesis to address identified knowledge gaps. Firstly, Flail-space s lateral thoracic impact velocity was validated against existing lateral PMHS thoracic impact tests. The validated velocity was then considered as an additional lateral thoracic injury criterion for assessing lateral thoracic injuries resulting from rollover crashes. Secondly, thoracic injuries from real-world vehicle rollover crashes were examined based on occupant seated position and vehicle rollover direction. The results indicated that there is a difference in resultant thoracic injuries based on occupant seated position and rollover direction, which future studies need to consider. Thirdly, correlations between vehicle panel damage and serious thoracic injuries were investigated from real-world rollover crashes. The results indicated that there are associations between vehicle panel damage and serious thoracic injuries. Fourthly, a real-world rollover crash where the driver sustained serious thoracic injuries was analysed using computer simulations to study thoracic injury aetiology and its association with vehicle panel damage, as identified in the third study. Further, thoracic injuries were assessed against existing thoracic injury criteria and the lateral thoracic impact velocity criterion from the first study. The findings indicated a low likelihood of the occupant sustaining a thoracic injury. However, the results indicated instances in the rollover sequence that need to be studied in further detail, highlighted the sensitivity of thoracic injuries to initial occupant position and indicated the need for introducing thoracic oblique loading sensitivity in future ATD designs.
This thesis has provided a new lateral thoracic injury criterion; and identified vehicle, occupant and environment characteristics which need to be considered for future thoracic injury aetiology in rollover crashes studies.

Improving young novice drivers' speed management behaviour
Dr Oleksandra Krasnova
Supervisor: Dr Brett Molesworth
Road related fatalities are a global problem. In New South Wales, Australia, excess speed is thought to be one of the leading contributing factors for fatal motor vehicle crashes. Speed management remains an elusive skill for many young drivers. Using lessons learnt from aviation and road domains in Australia, the present research aimed to develop a new practical approach to improve young drivers' speed management behaviour. Experiment 1 tested the effect of three cognitive-based training approaches, namely: self-explanation, reflection and combined feedback (i.e., performance, financial implications, safety implications or combination) in a driving simulator to improve young drivers' speed management behaviour immediately post-training, one week post-training (short-term) and six months post-training (long-term) in three different speed zones (low, moderate, high). The results reflected positively on both self-explanation and combined feedback. Self-explanation improved young drivers' speed management behaviour in the low-speed zone of 40km/h, across all time periods. However, combined feedback led to improvement in all three speed zones across all time periods. Experiment 2 examined which aspect of the combined feedback (i.e., performance, financial implications, safety implications or combination) yielded positive changes in speed management under the same test conditions as in Experiment 1. The results reflected positively on the different aspects of feedback, with the elements of performance, finance and safety feedback yielding the most positive results. Experiment 3 moved from the laboratory out onto the road, and investigated the effect of two cognitive-based training interventions (i.e., combined feedback and self-explanation) on young drivers' speed management behaviour in the operational environment. In contrast to the previous two experiments, participants were tested at two post-training time periods, namely: immediately post-training and one week post-training. The results revealed that combined feedback was the most effective training intervention, followed by the combination of self-explanation and combined feedback, at each time period, and in all three speed zones. The findings from the three experiments provide insight about various training methods and their effectiveness in improving young drivers' speed management behaviour.

A combined spatial and temporal level of service framework for airport terminals
Dr Tae Hyun (Danny) Kim
Supervisor: A/Prof Cheng-Lung (Richard) Wu
The fundamental units for the measurement of the level of service (LOS) at airport terminals are per passenger space and waiting time. The IATA framework measures passenger density and waiting time separately, which could lead to conflicting measurements when passenger density and waiting time indicates different LOS levels. This thesis therefore aimed to develop a combined spatial and temporal LOS (ST-LOS) framework to guide terminal planning.
In the first stage of this thesis, a passenger survey was conducted, which involved the Repertory Grid Technique (RGT), a questionnaire, an experiment, and a semi-structured interview. Results showed that two-thirds of the participants perceived a decreased service quality associated with crowdedness at airports, and 85% of the RGT constructs indicated dissatisfaction with regard to space. 47% of the senior Australian participants previously complained about inter-person-spacing (IPS) at airports, while none of the senior Korean participants did so. The young Australian participants were tolerant of smaller personal space, 15cm smaller IPS on average, compared to the senior Australian participants. These findings revealed a moderating role of age and cultural background in the personal space demand of passengers, and suggested the necessity of an alternative LOS standard that incorporates the concept of perceived personal space as a spatial LOS attribute.
In the second stage, computer simulation was used to test the proposed ST-LOS framework under different terminal and passenger settings. The ST-LOS was built by combining the temporal and spatial measurements and aimed to allow at least 50% of passengers to experience the optimum LOS. In the base simulation, 65% of passengers experienced the optimum LOS according to the ST-LOS. However, only 22% of passengers experienced the optimum LOS defined by the current IATA standard. To meet the IATA standard, the check-in queue width had to be reduced from 1.5m to 1.2m that differed from the recommended queue width (1.4m~1.6m) by IATA. A case study based on Sydney International Airport illustrated the application of the ST-LOS framework for LOS measurement, revealing that our ST-LOS framework better represents the LOS that passengers will experience, and that incorporating personal space demand of passengers will improve the LOS standard.

Market Spill-Recapture Model for Airline Demand Unconstraining
Dr Tomasz Drabas
Supervisor: A/Prof Cheng-Lung (Richard) Wu
Predicting the demand for future flights accurately is highly important in order to ensure the survival of any airline. In order to reliably forecast the number of potential passengers Revenue Management forecasting methods need error-free true demand data. The true demand for a booking class is the number of passengers willing to purchase the ticket assuming the booking class is always available for purchase. However, due to aircraft's physical capacity limitations and historical Revenue Management decisions, the collected booking data seldom represents true demand.
Adding to the true demand modelling complexity, airline customers' preferences and experiences vary significantly. Not account for these phenomena the true demand may result in erroneous predictions of the true demand. In addition, with similar options offered by various airlines the substitution patterns manifest strongly in observed booking numbers.
To account for the varying preferences of passengers and for correlations between products we introduce a novel Segment Specific Cross Nested Logit Model with Brand Loyalty. The model explicitly handles substitution patterns between all the market options, allows tracking changing customers' preferences and accounts for their past experience. Using data from a Stated Preference experiment conducted among 360 Australians we showed that our discrete choice model constantly outperformed the more simplistic methods by 0.04 to 0.061 in terms of the adjusted R2, attaining results on par with more sophisticated models. At the same time our model was only marginally more computationally expensive than the simpler models.
In this thesis we also propose a novel unconstraining model. The Market Spill Recapture Model delivers true demand estimates for all the booking classes offered by all the airlines in a specific market. Using an agent based booking simulator developed for this research, with discrete choice models from the Stated Preference experiment driving virtual passengers decisions, we simulated booking data for six virtual airlines. The Segment Specific Cross Nested Logit Model with Brand Loyalty was used to model demand interactions in our unconstraining model. For the simulated data our model delivered true demand estimates that were between 1 percent to 10 percent more accurate than the Multi-Flight Recapture Method.

Human factors and ergonomics as a scientific discipline: the relationship between theory, research, and practice
Dr Amy Chung
Supervisor: Prof. Ann Williamson
Human factors and ergonomics (HFE) is an applied scientific discipline with a strong emphasis on evidence-based practice. However, in reality, there is often a `research-practice gap¿. This is characterised by ongoing tension between researchers and practitioners, and low research utilisation in practice. A series of studies were conducted to examine the nature and extent of this issue. Study 1 was an international survey of 587 HFE professionals to examine the nature of the research-practice gap. Results showed that practitioners are more likely to perceive access and applicability of research to be barriers to applying research findings in practice compared to researchers. Study 2 and Study 3 then examined the extent of the research-practice gap in an international survey of 309 HFE professionals. Study 2 investigated HFE professionals¿ evaluations of journal article attributes, and Study 3 investigated their selection of journal articles in an online setting. Results of Study 2 and Study 3 showed that both researchers and practitioners in HFE perceive journal article attributes relating to practical significance to be much more important than attributes relating to theoretical significance, and researchers and practitioners make similar selections of journal articles to read. These results suggest that the research-practice gap may not be as large as previously thought. More importantly, these results suggest the possibility of a theory-research gap in HFE. Study 4 examined trends in the research published in HFE peer-reviewed academic journals. A content analysis of 425 journal articles published in Human Factors, Ergonomics, and Applied Ergonomics from 1960 to 2010 was conducted. Despite increased contribution from researchers, the published research has a stronger focus on practical applications compared to theoretical implications. Thus publication practices in HFE could be improved to enhance both the use of theory and specification of the practical application of findings. These results suggest that the heavy emphasis on the link between research and practice may have been misguided, and more attention should be given to the link between theory and research to ensure that HFE practice rests on firm scientific foundations.

Normal operations monitoring
Dr Louise Raggett
Supervisor: Prof. Ann Williamson
Managing risk has become increasingly important in modern organisations. Managers recognise it is difficult to manage without measurement, however, it is difficult to know what to measure in order to drive the continuous safety improvements, promised by modern safety management systems. One industry where safety performance improvement appears to have stalled, is aviation ground operations. Unlike the flight operations, which is now regarded as an Ultra-safe system (Amalberti 2001, p. 109) ground aviation has languished behind the rest of the industry (Verschoor and Young 2011), with activities on the ramp now accounting for more than a quarter of all aviation incidents (Balk and Bossenbroek 2010). In recent years, both damage to aircraft on the ground, as well as harm to ground personnel have escalated (Passenier 2015 p. 38).The aim of this research was therefore to review current approaches to safety measurement and develop a new data collection tools to inform evidenced-based interventions that will reinvigorate ground safety improvement.
To achieve this models and measures influential to aviation safety are reviewed. The Threat and Error Management Model (TEM) and Line Operation Safety Audit (LOSA) method (Klinect, Murray, Merritt and Helmreich 2003) are critically examined for their suitability. Strengths and weaknesses are identified, with the aim of building on the benefits of LOSA whilst addressing key concerns about LOSA s validity. A new model and method are proposed known as Normal Operations Monitoring (NOM). NOM is applied in a ground handling organisation, with data collected from over 1300 observations of aircraft turnarounds.
The results provide novel data about human and safety performance and suggest new opportunities for safety interventions and improvement. Implications for ground safety are explored as well as the potential applications and benefits of NOM generally. The final discussion explores ways in which the current research and NOM tools could be taken forward as a method for informing and improving safety management in high hazard industries.

An investigation into human factors influencing driver behaviour and traffic law enforcement in Jordan
Dr Faisal Magableh
Supervisor: Prof. Raphael Grzebieta
This dissertation investigates the human factors influencing driver behaviour and traffic law enforcement in Jordan. The research was carried out using two separate survey studies
that aimed to determine the factors that are significantly associated with receiving traffic fines and being involved in crashes and to investigate the perceptions of drivers and traffic Police concerning traffic law enforcement and driver behaviour. A total of 501 drivers and 180 Police officers were surveyed.
Study one (I) focussed on driver attitudes, behaviour and compliance factors. The results showed that gender modified the relationship between some independent factors and study outcomes. Crashes for males were significantly associated with previously receiving distraction fines, instances of being stopped by Police, being intimidated by other drivers and previously receiving traffic fines. Crashes for females were significantly associated with violating traffic signs, being intimidated by other drivers and previously receiving traffic fines. Study I also showed that more than half of drivers reported a sense of unfair treatment and Police selectivity and favouritism regarding traffic law enforcement. These factors might be profoundly affecting many Jordanian drivers' motivation to violate traffic rules.
Study two (II) investigated Police officers work environment, enforcement perceptions and practices. The results showed that many Police officers complained of their work conditions, life and work pressures and unpleasant treatment when dealing with drivers. There was some lack of understanding of the role of the religion in road safety and an underestimating of the level of risk of some driver behaviour as well as a reduced capacity in assessing crash contributors. Some factors related to a driver s networking, authority, position and nepotism were found to affect Police enforcement decisions.
The findings of both studies are discussed and some recommendations have been suggested with regard to drivers and traffic Police to improve road safety in Jordan. In particular, it appears that the role of religion along with Jordanian social culture in regards to care for family and individual safety on Jordan s roads, and respect for road laws and the Police who enforce them, can be utilised to improve road safety in Jordan.

Close enough is not good enough: improving the reliability of accident and incident classification systems in high hazard industries
Dr Nikki Olsen
Supervisor: Prof. Ann Williamson
This thesis aimed to understand the factors influencing the reliability of accident and incident classification systems in high-hazard industries and subsequently, to develop methods to achieve high consensus in these classification systems. To explore reliability the Human Factors Analysis and Classification System and its Australian Defence Force derivative version were used as case studies for reliability assessment. The reliability of each system was assessed and factors associated with coder expertise, training and usability explored. The research was then extended across all accident and incident classification systems by using classification theory to guide a strategic review of reliability. This involved qualitative and quantitative analyses of the factors affecting user consensus conducted across more than twenty classification systems across six safety-critical industries. As a result four recommendations were developed for improving the reliability of classification systems. These included designing domain-specific systems, limiting system size and reducing psychological and bias-causing terminology. These recommendations were tested through application to the Australian Defence Force version of the Human Factors Analysis and Classification System. Promisingly, they improved reliability by more than twenty percent across all levels of the classification system. This research has built on previous studies of improving the reliability of accident and incident classification systems that have largely been limited to improvements of specific systems. The recommendations enable a more systematic approach to improving reliability across all accident and incident classification systems within high hazard industries. As a result, the likelihood of effective hazard intervention strategies will be increased and should lead to improvement of safety in high-hazard industries.

An evidence-based safety management system for heavy truck transport operations
Dr Lori Mooren
Supervisor: Prof. Ann Williamson
The aim of this thesis research was to find ways to improve safety in the heavy vehicle transport industry through the development of an evidence-based safety management system. This research was undertaken in light of disproportionate crash and injury risks associated with the heavy vehicle transport industry in comparison with other industries and other road users. The nature of the trucking industry presents some unique challenges for safety management at an organisational level. This thesis argues that a systems approach with evidence-based safety management elements can be developed into an intervention program that is likely to improve safety outcomes in the heavy vehicle transport sector.
Drawing from the knowledge from prior occupational safety and road safety research (Study 1), a study of safety management characteristics comparing those in good safety performing heavy vehicle operators and poor safety performers sought to synthesise the distinguishing features between them. Two empirical studies were conducted (Studies 2 and 3). The findings of these studies provided the basis upon which to build a safety management system (SMS) suitable for heavy transport vehicle operations. This process resulted in the identification of 14 safety management characteristics that have strong research evidence for inclusion in a safety management system (SMS) for heavy truck operations. These findings, together with analysis of sound theoretical models to underpin the SMS, were used to shape the SMS. The SMS features three spheres of management practices risk assessment and management, driver risk management and safety culture management. Drawing from the literature, a dynamic model of a safety management system is presented and explained. The original aim of this thesis research has been met, providing an evidence-based safety management system that is likely to reduce crash and injury risk when applied to heavy vehicle transport operations.

Maximising mobility and minimising injury risk in aged care: indexing environment related manual handling of people (MHP) risk controls that may influence patient mobility
Dr Robyn Coman
Supervisor: Dr Carlo Caponecchia
The manual handling of people (MHP) is a core activity for care workers in residential aged care, and is known to be associated with high incidence of musculoskeletal disorders (MSDs). Promoting patient mobility within the manual handling (MH) interaction is an endorsed MHP risk control intervention strategy that should reduce risk exposure for staff, and may also benefit the patient through increased independence and autonomy. However, while staff MHP intervention outcomes, have been extensively investigated, evidence of the impact on patient outcomes, including mobility, is limited. This project investigated the nature and extent of environment related MHP interventions that may influence patient mobility outcomes through review of the literature, trial of an existing PH assessment tool, and subsequent development of the Pro-Mobility Patient/Person Handling Assessment Tool or Pro-Mob for this specific purpose.

Characteristics of serious head injuries in pure rollover crashes and an evaluation of their replication in a dynamic rollover test
Dr Garrett Mattos
Supervisor: Prof. Raphael Grzebieta
Serious head injuries are a major concern in light passenger vehicle rollover crashes. There are efforts in the US and Australia to assess the feasibility of developing a dynamic rollover test to evaluate the crashworthiness of a vehicle in a rollover. However, detailed information about the characteristics of serious head injuries in single-vehicle single-event, i.e. pure, rollover crashes, and regarding the capabilities of the dynamic rollover test devices chosen for the separate US and Australian investigations, is lacking. To address this knowledge gap, two crash databases are investigated to describe the characteristics of head injuries and associated crash factors for pure rollover crashes in Australia and the US. Results from 80 dynamic rollover tests are analysed to evaluate the effects various test methods have on replicating and measuring ATD head response associated with serious head injury. The structural and kinematic responses of 48 vehicles in 83 tests conducted using the Jordan Rollover System (JRS) are evaluated. Logistic regression analysis is used to assess the relationship between the structural response of JRS-tested vehicles, and the occurrence of incapacitating or fatal injury in single-vehicle rollover crashes. Finally, a human body finite element model is subjected to impact conditions identified from dynamic rollover tests to demonstrate the effect of rollover-related impact parameters on a pattern of head and spine injury observed in crash data.

The biomechanical determinants of sport-related concussion: Finite element simulations of unhelmeted head impacts to evaluate kinematic and tissue-level predictors of injury and investigate the design implications for soft-shell headgear
Dr Declan Patton
Supervisor: Prof. Raphael Grzebieta
Concussion is prevalent in collision and contact sports and, therefore, an injury of specific interest. Laboratory and epidemiological research in football codes, in which headgear is not mandatory, has demonstrated the limited effectiveness of headgear in preventing concussion. To further understand the biomechanics of concussion and develop effective prevention methods, it was necessary to investigate the dynamics of head impacts in sport.

She'll be right: The link between attitude, risk perception, and experience in Australian general aviation
Dr Justin Drinkwater
Supervisor: Dr Brett Molesworth
Commercial Aviation in Australia has an enviable safety record, however, the General Aviation (GA) industry’s record is less impressive. Commercial pilots in Australia will by-and-large be trained in the GA industry, it is a critical link in the training of pilots, influencing them in the formative period of their careers. This research investigates the attitudes and behaviour of pilots in this stage of their career to determine whether or not the attitudes and behaviours of pilots at this stage of their career are inappropriate or if there are any unexpected attitudes prevalent. Additionally, the correlation between attitudes, risk perception, risk tolerance and behaviour in pilots is poorly represented in the literature. Therefore this research investigates the attitude towards risk, the perception and tolerance of risk and the risk behaviours of Australian commercial pilot candidates

An investigation into factors influencing hazardous materials truck crashes in Thailand
Dr Junjira Mahaboon
Supervisor: Prof. Raphael Grzebieta
A program of research was conducted to investigate factors influencing hazardous material (hazmat) vehicle crashes which are a significant road safety problem in Thailand and many other countries. The aims were to evaluate crash causes with regard to driver and organisational factors relating to hazmat truck crashes in Thailand.

Terminological similarity between medical error taxonomies and incident reports: impact on taxonomy usability, reliability, and usefulness for preventing medical errors
Dr Ibrahim Taib
Supervisor: Dr Carlo Caponecchia
Various medical error taxonomies have been proposed in the literature. It is possible that because different medical error taxonomies utilise different categories, such taxonomies classify different information. This thesis reviewed published medical error taxonomies using a human factors perspective. It was found that two-thirds of the taxonomies classified systemic factors and only a third utilised theoretical error concepts. Additionally, medical error taxonomies utilising different terminologies may not share information effectively, most probably because some information may be loss during the integration process. This thesis then examined the difference between generic and domain-specific medical error taxonomies.

Improving drivers' risk management behaviour: an assault on speeding
Dr Prasannah Prabhakharan
Supervisor: Dr Brett Molesworth
Research from the aviation industry has demonstrated that a cognitive training method, termed episodic training, can improve pilots' risk management in a simulated environment. Drawing from this research, experiment 1 aimed to investigate whether episodic training could produce similar improvements in motorists' risk management behaviour, namely in the area of speeding. The results revealed that episodic training was an effective method to reduce young novice drivers' tendency to speed in a simulated driving environment. Experiment 2 aimed to examine the impact of episodic training on drivers' cognitive resources, with the introduction of a secondary task. The results revealed that implementing a speed management strategy through episodic training was successful in isolation; however, when performed in conjunction with a secondary task, there was a trade-off in terms of how cognitive resources were allocated. This result prompted experiment 3 to explore the cognitive underpinnings of how young novice drivers distributed cognitive resources when performing a dual-task and whether it was possible to train how these resources were allocated. Cognitive resource allocation was calculated by assessing performance on a dual visual and auditory computer task. The results from this experiment revealed that individuals opted to evenly distribute cognitive resources in the dual-task exercise rather than allocate based on the demand characteristics of the task. The results also revealed that cognitive resource allocation can be trained by providing explicit feedback about performance.

Automation acceptance in air traffic management
Dr Marek Bekier
Supervisor: Dr Brett Molesworth
An increased use of automation within the ATM environment is seen to be one possible enabler for a significant capacity increase of the ATM system. However, often automated tools and systems are rejected by the Air Traffic Controllers unwillingness to cooperate with it. This research defines the threshold along the automation dimensions "decision selection" and "action implementation", where the support of the operators tips into skepticism and refusal to collaborate with it.

The choice behaviour of shippers in selecting cargo providers and the effects of choice behaviour on the formation of business partnerships in the emerging airfreight business structure
Dr Jungkyu Choi
Supervisor: A/Prof Cheng-Lung (Richard) Wu
This research defines factors which influence a customer's decision to choose an airline in cargo markets and to analyse the importance and relationship between each of the factors. In addition, it analyses the competition between airlines by using certain key variables affecting competitiveness. Also this research analyses the productivity in major airlines in cargo markets by several factors.

The effects of low-cost carriers on regional dispersal of domestic visitors in Australia
Dr Tay T.R. Koo
Supervisor: A/Prof Cheng-Lung (Richard) Wu
This research examines tourists' travel mode choice; in particular, the research examines the mode choice as a key factor influencing the link between affordable air travel and dispersal. With the aid of stated choice experiments and discrete choice models, three issues were examined: (1) the differences in the dispersal behaviour between low-cost carrier and network carrier users; (2) the effect of regional destination transport on dispersal; and (3) the effect of low airfares on the bypass of ground-mode-reliant regional destinations.

Frames in the flight deck: a sociological approach to situation awareness
Capt./Dr Simon Henderson
Supervisor: Prof. Jason Middleton
The aim of this research is to develop an alternative, sociologically based approach, largely drawn from Erving Goffman's (1974) Frame Analysis, and assess whether it can be used to effectively describe, analyse and discuss SA. This work establishes that Goffman's (1974) frame analysis theoretically supports the major underlying concepts of the SA construct. SA is shown to be a meaningful and observable social phenomenon. Additionally, a method derived from frame analysis is used to examine and analyse the observed intersubjective SA processes. Lastly, practitioner based notions of SA are shown to be equivalent to that of "frame".

Human factors in high-risk aviation: an analysis of influences upon aviation safety in the Australian Defence Force
Dr Boyd Falconer
Supervisor: Dr Steve Shorrock
Since 1990, aviation mishaps have cost the Australian Defence Force (ADF) the loss over 44 highly trained personnel and 23 aircraft, and a financial loss of several hundred million dollars. In contrast, Australian Regular Passenger Transport (RPT) operations have incurred no fatalities or aircraft losses. Whilst at first glance one may suspect the hazards of combat have influenced the significant losses within ADF aviation, Boyd's research shows that none of the losses have occurred whilst operating in military campaigns. Equally significant is the finding that only one ADF aviation mishap occurred outside Australian territories. Boyd's research provides a new analysis of data collected from approximately 1,000 ADF aviation professionals by an Australian Defence Force survey based on the Flight Management Attitude Questionnaire developed by the University of Texas Crew Research Project. A key innovation of Boyd's research is that, unlike previous research that merely compares culture and aviation safety between countries, his thesis examines the differences within the ADF organisation via a methodology based on military-specific categories of personnel groups or sub-cultures. Boyd's research highlights the significant impact of military rank upon attitudes towards flight management: a finding with safety benefits through human performance in both military and commercial aviation in Australia.

Observations of cosmic ray exposure levels in the higher southern latitudes and validation of predictive computer models.
Capt./Dr Ian Getley
Supervisor: Prof. Jason Middleton
Aircrew and passengers are subject to cosmic rays which have a higher intensity at altitude than at the earth's surface. In the Southern hemisphere in the Australian sector, the proximity of the South Magnetic Pole means that cosmic ray intensity is higher than elsewhere around the world. This project aims to measure cosmic ray intensity during a number of southern hemisphere flights where data is non-existent, and to compare the data with predictive computer programs.

Assessment of stress and cardiovascular function in trainee pilots
Dr. Lihong Kong (School of Biomedical Engineering)
Adaptation of cardiovascular response to stress can contribute to imrpovement of task performance.
The project aims at assessing trainee pilot cardiovascular response (pulse rate and blood pressure) under various conditions of applied stress, and determining changes over time. Visual, auditory, mathematical and logical stimuli were applied, with differing responses. Not all subjects respond in the same way. It is planned to compare these test results with results of flight training assessment.

An empirical investigation of the relationships between airline service quality, perceived price, service value, passenger satisfaction, airline image, and passengers' behavioural intentions.
Dr. Jin Wu Park
Supervisor: A/Prof Cheng-Lung (Richard) Wu
This research seeks to investigate the relationship of airline service quality with price, service value, airline image, passenger satisfaction and passengers' behavioural intentions. By acquiring data from both Korean and Australian passengers, the purpose of this research is to study and to understand choice behaviour of airline passengers. To test the conceptual framework, path analysis technique via Structural Equation Modeling is applied to data collected from airline passengers.
