Exploring ways of enhancing creativity in engineering education to promote innovation: Action research in engineering design

This research is based on educational research practice and seeks to address the ways of enhancing creativity in engineering education. The study aims to help students nurture their creative thinking skills during design process in their studies. In addition, it also aims to support instructors in their teaching approach to enhance students’ creative thinking abilities. This study is an important step, with a holistic approach, in suggesting creativity and creative thinking be inherent and integral parts of every engineering curriculum. It makes a major contribution to research on creativity in engineering education.

How do risk factors for sexual and non-sexually violent offenders manifest and change in custody?

The research investigated how dynamic risk factors manifest in custody and change over time. These are important issues because they contribute to decision-making throughout sexual and non-sexually violent offenders' incarceration. Study 1 surveyed psychologists to identify behaviours that sexual offenders engage in during their incarceration, subsequently informing the development of a behavioural checklist. Study 2 validated the Satisfactory Behaviour Rating Guide, which evaluates non-sexually violent offenders' behaviour prior to gaining parole. Study 3 included four methods of measuring sexual offenders’ change during a treatment program. These studies provided an in-depth understanding, and revealed the complexities, of behavioural monitoring and change measurement in custody.

Managing unskilled migrant workers in the sme sector: a study of managers in Australia

This thesis examines the perspectives of managers of unskilled migrant workers in Small to Medium Enterprises (manufacturing firms). Interviews were conducted with managers and regulators. The managers reported frustrations emerging in their dealings with some migrant workers, with several situations developing into multi-faceted problems for ongoing periods. Several managers were found to be inept in their management skills and attitudinal differences emerged between senior- and middle-level management. Continued problems were experienced by managers of migrant workers yet to adapt to local work expectations. The thesis enhances understanding of some of the problems faced by managers and highlights the importance of training for both managers and migrant workers.

Violent offenders' within-treatment change in dynamic risk and protective factors: associations with violent recidivism

This thesis investigates whether within-treatment changes on intermediary treatment targets are associated with violent reoffending at post-treatment follow-up. Taken together, the results do not provide evidence that changes in dynamic risk and protective factors translate into reductions in violence propensity. Furthermore, it remains unclear how protective factors operate in relation to reductions in risk. Developing a greater understanding of change processes and how violent offender treatment works is critical, not only in terms of delivering more effective interventions, but in terms of managing violence risk and promoting public safety.

Coral cores as record of past sea surface temperature of the Talang Besar Island (South China Sea)

The climate of the South China Sea is highly affected by the monsoon seasons. Trace elements ratios incorporated in skeletons of long-lived corals are considered as useful climate proxies. This study is based on measuring the Sr/Ca ratio (by ICP-OES) in a massive Porites species core sampled off Talang Besar Island for long term sea surface temperature reconstruction. The coral core recorded higher sea surface temperatures than the satellite data and captures only few past ENSO events. This study can help to understand past climates and environmental changes, and therefore help in improving future climate predictions.

Social enterprise and sustainability in the nonprofit sector: A theoretically grounded approach

This thesis provides a performance based theory of financial sustainability for social enterprises in the nonprofit sector in South Asia drawing on field research conducted with social enterprise organisations in Bangladesh, India and Sri Lanka. The research adopts grounded theory method (GTM) for data collection, analysis and theory generation. Guidelines are provided for practitioners in how to operationalise the theory.

A finger-mounted obstacle detector for people with visual impairment

impairment. The proposed assistive prototype detects obstacle using ultrasonic sensor in real-time and produce audio feedback using transducer. Many previous studies proposed prototypes that are either heavy, bulky, obstructive or high computational power leading to high power consumption. However, the research successfully designed a prototype to be small, light-weight, non-obstructive, low computational power, low cost, portable and wearable. The proposed prototype can potentially assist people with visual impairment in reducing the rate of collision or accident against obstacles around them.

Estimating the effect of vegetation on urban temperatures

Thesis focused on the mitigation of Urban Heat Island, this phenomenon can define as temperature in the city core always higher than rural areas by 7 oC or more in some mega cities like Melbourne which I use it as a large case study. The mitigation process studied the effect of 27 parks on air and surface temperature during the course of one year. In addition, the other weather parameters such as wind speed, humidity and precipitation were measured for different distance from the edge of parks towards many sights inbound and outbound. Vegetation within parks can be designed in the city core and far could reach to 9 km to diminish temperature up to 5 oC from the park edges to 3 km.

Trapping ultracold atoms in submicron period magnetic lattices

Periodic arrays of magnetic microtraps patterned on a magnetic film provide a potential complementary tool to conventional optical lattices for trapping ultracold atoms. Dr. Tran’s thesis presents the trapping of Rubidium atoms in submicron period triangular and square magnetic lattices on an atom chip. The results demonstrate an advance in using magnetic lattices to simulate novel condensed matter phenomena and also provide insight into the study of atom-surface interactions.

A game-based spatial navigation tool for children with visual impairment

A mobile serious game named Hungry Cat has been developed in this research for visually impaired children. The game prototype developed was evaluated with 30 visually impaired children from a local boarding school. Two tests, the food finding test and the wire net test were conducted to determine if playing the game will help the participants to gain spatial information through the exploration of virtual rooms. The final results show that the game is indeed able to convey spatial information to visually impaired children and help them to make spatial mental maps of the rooms.
