The Impact of Spiritual Intelligence on the Organisational Commitment, Occupational Stress and Wellbeing of Temporary Migrant Workers in Australia
No full textThis study investigates how spiritual intelligence affects organisational commitment, occupational stress, and well-being among temporary migrant workers in Australia, using the Conservation of Resources (COR) theory as a framework. It also explores how organisational commitment and occupational stress mediate the relationship between spiritual intelligence and employee well-being. The findings highlight the significance of spiritual intelligence in reducing stress, enhancing commitment, and improving overall well-being. This research offers valuable insights for developing workplace strategies that support temporary migrant workers, ultimately contributing to a more resilient and healthy workforce.</p
Recycling excavated soil as a natural supplementary cementitious material
No full textThis thesis addresses the environmental challenge of managing excavated soil from urban infrastructure expansion. It develops a rapid and cost-effective method for measuring kaolinite, a clay mineral, in soil. The research explores recycling this soil as a component in high-quality cement, showing that soil with high kaolinite content can produce mortars as strong as or stronger than traditional cement. It also investigates the use of nano-calcined soil in improving cement properties and enhancing hydrophobic characteristics. This work promotes sustainable construction practices, reduces landfill waste, and supports a circular economy in the construction industry.</p

Polarization tailored optical response of nano-micro-textured surfaces over THz-IR-Visible spectral ranges
No full textThis thesis investigates how nano or macro structures on surfaces can be used to control light in precise ways across different wavelengths, including infrared and visible light. By developing new techniques to manipulate light with these structures, the research enhances our understanding of optical materials. This knowledge can lead to advances in technologies such as improved sensors, imaging systems, and communication devices. The potential benefits to society include more efficient and effective optical devices, which can be used in healthcare, environmental monitoring, and information technology.</p
Parametric study of lignin extraction from EFB using LTTM and combined kinetic studies of lignin in the presence of minerals
No full textThis research explores a sustainable method for extracting lignin, a key component of plant materials, using a new, environmentally friendly solvent mixture made from malic acid, sucrose, and water. The study shows that increasing temperature and extraction time, along with adjusting the ratio of plant material to solvent, greatly improves the efficiency and purity of lignin extraction. With up to 88% purity achieved, this approach not only maximizes the value of lignin but also supports greener practices in biomass processing. By advancing this technique, the study contributes to more efficient use of natural resources and reduction of waste.</p
Integrated Assessment of Established Constructed Wetlands for Stormwater Treatment in Urban Areas: Modelling and Management
No full textThis research investigates the long-term effectiveness of constructed wetlands in stormwater treatment in Melbourne, Australia. Despite their rising prevalence in urban development, post-construction monitoring of constructed wetlands remains insufficient, with current guidelines overlooking heavy metals. Analyzing water samples from five established wetlands revealed frequent non-compliance with pollutant reduction targets, indicating design and management flaws. By refining the design model with field data and employing multivariate modeling and machine learning, pollutant reduction accuracy is improved. The findings offer cost-effectiveness sampling strategies and critical insights for local governments to enhance wetland design and management, ultimately benefiting urban water quality and ecosystem health.</p
The Psychological Change Processes in the Antidepressant Effects of Psychedelic-Assisted Psychotherapy: A Mixed Methods Investigation
No full textWhilst research into psychedelic-assisted psychotherapy has produced promising results in the treatment of depression, further investigations are needed into how it works to produce antidepressant effect. The current thesis involved a multi-faceted scoping investigation of possible psychological mechanisms of action of psychedelic-assisted psychotherapy for depression, and includes three individual studies: a systematic review, Delphi study, and qualitative interviews with participants in a clinical trial of psilocybin-assisted psychotherapy for treatment resistent depression. Results from all three studies were synthesised to produce a proposed framework of psychological mechanisms of action in psychedelic-assisted psychotherapy to support future research in the field.</p
Production of Bacterial Cellulose from Agricultural Wastes for Tissue Scaffold Application
No full textBacterial cellulose is a bio polymer produced by certain bacteria, renowned for its high purity, strength, and biocompatibility. Producing BC from agricultural wastes and by products, offers an eco-friendly alternative to conventional methods, reducing environmental waste and promoting sustainable practices. Utilising these wastes not only lowers production costs but also mitigates the environmental impact of agricultural by-products. In the biomedical industry, BC serves as an excellent material for tissue scaffolds due to its ability to support cell attachment and proliferation, enhancing tissue regeneration and healing. This approach bridges sustainable agriculture with advanced medical applications, benefiting both society and the environment.</p
Millisecond pulsar timing and gravitational wave searches with the MeerKAT radio telescope
No full textGravitational-wave observations have transformed the way astronomers study compact objects such as neutron stars and black holes. Current detectors can only observe the mergers of objects on the order of a few to hundreds of solar masses. To observe more massive mergers, a different type of detector is required. By monitoring the emission from an ensemble of pulsars in a pulsar timing array, a Galactic-scale detector can be formed to detect these. This thesis explores the first efforts to detect gravitational waves with a new, highly sensitive pulsar timing array: the MeerKAT Pulsar Timing Array.</p
Amplifying Unheard Voices - Towards Inclusive Innovation and Development
No full textAn increasingly diverse engineering workforce supports innovation and creativity. However, whether diversity translates to improved organisational performance depends on whether employees are able to voice issues and ideas. Voice is conceptualised as employees' ability to speak up and be heard. While much research has been done by industrial relations, human resource management, and organisational behaviour scholars, their different ontological assumptions have made it difficult to integrate the learnings. As such, much is still unknown about how socioorganisational factors influence employee voice, particularly in a more diverse workforce.</p
