This thesis analyses how contemporary feminist and women’s-based campaigns have used social media platforms to challenge and resist dominant gendered discourses of women in the Australian mainstream media. Informed by post-structural feminist theories of discourse and power within a wider media studies approach, this thesis uses qualitative interviews and three separate case studies to analyse and contrast the assorted methods used by each case study to resist gendered discourses. It then contends that feminist and women’s-based campaigns can use social media to effect change, but that groups also need to be aware of issues related to intersectionality, and understandings of change within and outside of structural organisations.
Tennis has a challenging tri-nested scoring system of points, games and sets. The candidate used mathematical and probabilistic techniques to determine the optimal serving strategy. He challenged the traditional measure of importance of each point with a new way of looking at importance. He developed tests for analysing the independence between points and then analysed point-by-point data. He introduced the analysis of tennis as a game of point-pairs, one to each service court, and he measured the efficiency of the different scoring systems and tournament structures. Finally, he outlined strategic decision making at major events such as the Australian Open.
Ocean circulation models have been widely used to study the formation and distribution of surface sediments. In the present study a sediment transport model coupled with a hydrodynamic model and a wave model have been applied to the region of Port Phillip Bay in Victoria, Australia. Port Phillip Bay houses the largest container port in Australia, the Port of Melbourne. As a result it becomes increasingly important to understand and model or predict the behaviour of sediment in coastal areas and the Bay. The study couples a hydrodynamic model and a wave model with a sediment transport model in order to model suspended particulate matter at the surface.
Quantum correlations are correlations that arise from a unique feature in quantum mechanics: quantum superposition. The most famous example of quantum superposition is the Schrodinger’s cat state, where a cat is in a state of neither dead nor alive before an observer determines the cat’s status. This is not what we expect. Nevertheless, quantum superposition and correlations are routinely created in the laboratories with microscopic systems involving atoms and light particles. Can this counterintuitive notion be realised in the macroscopic world?
This thesis investigates this question by devising criteria that certify the existence of quantum correlations in mesoscopic/macroscopic systems. Powerful mathematical tools are used to simulate two quantum protocols in a mesoscopic system which have applications in quantum communication and computation.
The study of chemical elements and their absorption lines in the spectra of very distant quasars provides information on the state of the gas residing in the intergalactic medium and the different processes that occur during the early Universe.
This thesis investigates the properties of gas in the distant Universe in regions ionized by a uniform ultraviolet radiation field that accounts for photons produced by galaxies and quasars. We use a set of high resolution cosmological computer simulations to generate metal and hydrogen gas absorption line features as a result of the chemical enrichment from stars and supernovae.
Linear actuator based servo systems are used in many applications of a repetitive nature where they are required to track periodic references in the presence of plant uncertainties and nonlinearities such as nonlinear friction. Achieving the desired tracking accuracies in such uncertain linear actuator systems requires a control method which is capable of achieving perfect cancellation of the periodic uncertainties. One such control technique is the repetitive control method. To cater for the requirements of many LA systems with unknown nonlinearities and uncertainties, this thesis proposes robust repetitive control methods for achieving fast transient response, improved robustness and improved tracking performance.
Following the Fallout explores the design of narrative in the videogame series of Fallout. Through establishing the overarching structure of main quests, the supporting structure of side quests, and the players available actions, the thesis provides an exploration of how narrative is ‘active’ in videogames and how players are able to change the narrative progression of these games through their actions. Understanding the player’s effect on these structures ensures that developers, players and researchers can unpack the way videogame narratives are designed and played.
Dr Vohl’s thesis addressed fundamental problems facing Astronomy in the “Big Data” era relating to processing, visualisation, analysis, storage, and transfer of data. Many planned or ongoing projects aim at increasing the number of objects studied by several orders of magnitude. As both the volume and velocity at which data is generated increase, novel methods and analytical tools are required to help understand information hidden within data. Dr Vohl’s research investigated and introduced novel visualisation methods for real-time collaborative visual analytics in immersive environments; and explored data compression to accelerate data transfer within geographically dispersed, time-critical observing programs.
This study aims to evaluate the metabolic capabilities of Plantactinospora sp. KBS50, a rare marine-derived actinomycete isolated from Sarawak, as a potential source of novel compounds for antibiotics discovery. This study showed that KBS50 is an excellent producer of secondary metabolite compounds that potentially exhibit various biological activities including the antimicrobial properties. Hence, our findings may pave the way for the isolation, identification and characterization of potentially novel bioactive natural product compounds from Plantactinospora sp. KBS50 for the development of new drug candidates with important pharmaceutical applications.
This phenomenographic study explored undergraduate graphic design students’ experiences of how crowd critique in community forums and social networking sites could be used to gather feedback in design processes. Students unanimously described crowd critique as ‘brutally harsh and honest’, wherein learning outcome from their experiences revealed: (1) confidence and resilience to crowd critiques determined their eagerness to participate; (2) different student groups required facilitation to participate. Empirical analysis showed mature students displayed higher confidence and resilience with crowd critiques. From this study, an evidence-based pioneering pedagogical guideline to scaffold crowd critique initiatives (‘CrowdCritecture’ model) in undergraduate graphic design learning was conceived.
