Interest in the Learning of Mobile Touch Screen Technologies by Older Adults

There are many misconceptions by the wider public about older adults' capabilities and aspirations, especially their attitudes towards technology. Due to an absence of an interest framework for older adults to learn technologies, this research investigates the role that pre-existing interests and hobbies play in older adults' adoption of technology. The results show that when older adults are taught according to requests based on their pre-existing interests and hobbies, it encourages long-term adoption of technology and builds up their confidence in usages of touch screen technology. Consequently, improving older adults' well-being and quality of life.

The augmented bushwalk: contemplative play across digital systems and natural worlds

This research investigates how location-based augmented reality (AR) can alter our experience of bushland settings. While sound has been the primary mode of digitally mediating natural environments, the potential of augmented and mixed realities in these settings is less well understood. Through a practice-based methodology the research develops and analyses a prototype of an experimental mixed reality game titled Epiphyte. It proposes that contemplative play can be adopted to relate digital systems with the natural world, presenting five play design principles that demonstrate how location-based AR can support new place-making practices that re-shape our experience of bushland settings.

Metabolites produced by heat-tolerant endophytic fungi associated with Nepenthes ampullaria

Nepenthes species (commonly known as pitcher plant) can be found in Sarawak with several species endemic to the state. This plant can be divided into two groups, the highland and the lowland species. Climate change is one of the treats that are affecting the population of these plants especially the highland species as the lowland species are more adaptable to a warmer environment. This is due to the presence of endophytic fungi and their ability in producing metabolites which assist the plant's adaptation. This study can serve as a baseline study on the relationship between the endophytic fungi and Nepenthes.

Analysis and mitigation of the adverse effects of voltage sags and swells on wind farms

Wind farms have become an important source of sustainable electricity generation as renewable energy is becoming more and more popular around the world. The widespread adoption of wind farms causes some new problems. Wind generators are prone to damage during electricity grid instability and, therefore, some sort of protection is required for continuous operation of wind generators. This thesis focuses on the design of novel protection mechanism for wind generators during electricity grid instability. This will make the adoption of wind farms more feasible.

Self-defeating vs. self-deprecating humour: a case of being laughed at vs. laughed with?

Self-deprecating humour involves gently poking fun at oneself, whilst self-defeating humour is the excessive use of disparaging remarks about oneself. As these two humour styles may present in the same way, in this thesis it was examined whether observers could differentiate between the two and what this perception was based on (e.g., target self-esteem, funniness ratings or observer mood?). Humour plays an essential role in interpersonal relationships and can communicate information about an individual, however, research examining how humour is perceived is limited. Therefore this thesis addressed this gap examining the way in which targets using self-disparaging humour are perceived.

Finding and tracking local communities in social networks using differential geometry

Community detection methods in networks can be classified into two domains, global methods and local methods. Many networks are typically very large, making the global community detection methods impractical due to the computational expense. In addition, the constant stream of changes in the structure of networks makes it impossible for anyone to know the structure of the network fully. Therefore, local community detection algorithms, which do not need full knowledge of the structures of the network, have met with renewed interest. This thesis focuses on the problem of finding local communities and tracking them in dynamic networks using derivative-based geometric features by mapping the concepts of derivatives into graph space.

Influences of risk tolerance, perception and safety climate on unsafe behaviors in construction: workers and managers

Despite improvements made in construction safety over the last few decades, injuries and fatalities still occur on a regular basis. So, how to prevent unsafe behaviors on site for both workers and managers is an important issue. This research tries to understand how construction practitioners process safety risk information from the perspective of how people perceive and tolerate safety risks under certain safety climate. Based on these behavior analyses, it provides valuable practical insights for better and more effective construction safety management.

Investigation of anti-microbial activity and phytochemical characterisation of plant extracts

Traditional medicine is becoming widely accepted in Western countries. The Sarawak Biodiversity Centre, Malaysia, has provided extracts from their collection of Southeast Asian plants that were screened for their antibacterial and antifungal properties. From the fifty extracts, six were found to exhibit broad spectrum antibacterial activity. Use of these plants for the treatment of illnesses has been substantiated by our findings. Further research to understand the healing abilities reported for an Australian bush medicine obtained from the leaves of the Australian plant, Eremophila longifolia, identified two novel natural compounds and their discovery has advanced knowledge of an important indigenous medicine.

Efficient cohesive subgraph search in big attributed graph data

Models for finding subgraph previously have focused on graphs having no attributes. However, these graphs provide only partial representation of real graph data and miss important attributes describing a variety of features for each vertex in the graphs. As such real graph data are better modelled as attributed graph. Investigations for cohesive subgraph search in attributed graphs are still at preliminary stage. Searching cohesive subgraphs in an attributed graph can discover communities and find useful information for keyword queries. In this thesis, several cohesive subgraph models considering spatial and textual attributes are studied, which fit into various real applications.

Heideggerian phenomenology and the electrophysiological correlates of consciousness

Heideggerian phenomenology is used to inform a theoretical position regarding consciousness and its relationship to domains traditionally considered to be outside of consciousness, such as ‘the world’ or ‘matter’. This theoretical position is tested through four studies investigating the relationship between the neurobiological representations of conscious and non-conscious processes in the brain. It is suggested that such research contributes to a richer philosophical basis for the neurosciences and provides a novel avenue to explore the ways in which the brain is involved in the process of conscious perception.
