Judicial ethics and judicial misbehaviour: two sides of the one coin?
A Belated Interest in Judicial Ethics
âJudicial ethicsâ is a topic that has received close attention in Australia only relatively recently. This is perhaps surprising since the occasional propensity of judges to stray from the path of rectitude and propriety â to which judicial ethics are intended to be an antidote â is hardly a novel phenomenon
Electron Transport in Two-Dimensional Molybdenum Disulphide
This thesis will describe the experimental details used to make two-dimensional field-effect transistors using monolayer and bilayer transition metal dichalcogenides, including the fabrication of new sample holders required to cross between multiple experimental set-ups. Electron transport in these devices is measured at room temperature and at low temperature in a dilution refrigerator with a base temperature below 10 mK. Atomic force microscope lithography is explored as a technique for locally functionalising the surface of the device to create nano-features, with particular interest paid to the formation of quantum dots. Transport curves before and after lithography demonstrate the change in transport characteristics. A comprehensive study of device behaviour at room temperature is carried out. The effects of pumping and heating on the device are measured and discussed. Improvements in the transport occur from the removal of charge traps and the improved contact between the Ti/Au contact and the crystal. Low temperature (<10 mK) measurements of bilayer MoS2 devices show evidence of Coulomb blockade and the presence of small, unstable, naturally formed quantum dots. We suspect that interface states due to naturally occurring atomic defects in MoS2 which result in Fermi level pinning at room temperature are being probed here. The evolution of these states with magnetic field is measured, for devices positioned parallel and perpendicular to the magnetic field
Influence of Rooting on Stolon Branching in White Clover
The relationship between rooting and branching in stolons of white clover (Trifolium repens L.) was investigated in a field experiment, Half of a group of stolons was allowed to develop roots naturally, while for the other half root establishment was prevented by severing young roots before they made contact with the soil. Prevention of root establishment did not affect the numbers of branches which developed on nodes produced during the experiment, and it stimulated of branching on nodes which were already present. This result was unexpected on the basis of earlier observations of stolon growth and suggests that the relationship between rooting and branching is not causal (at least not during the early stages of branch development)
Ligand Tuning in Pyridine-Alkoxide Ligated Cp*Ir III Oxidation Catalysts
Six novel derivatives of pyridine-alkoxide ligated Cp*IrIII complexes, potent precursors for homogeneous water and CâH oxidation catalysts, have been synthesized, characterized, and analyzed spectroscopically and kinetically for ligand effects. Variation of alkoxide and pyridine substituents was found to affect their solution speciation, activation behavior, and oxidation kinetics. Application of these precursors to catalytic CâH oxidation of ethyl benzenesulfonate with aqueous sodium periodate showed that the ligand substitution pattern, solution pH, and solvent all have pronounced influences on initial rates and final conversion values. Correlation with O2 evolution profiles during CâH oxidation catalysis showed these competing reactions to occur sequentially, and demonstrates how it is possible to tune the activity and selectivity of the active species through the N^O ligand structure
Affective school atmospheres: an adventure through lively matters
In this thesis I explore the ways that atmospheres may be conceptualized and how these function affectively within school contexts. Incorporating broadly new materialisms methodologies, drawing heavily on the work of Deleuze and Deleuze and Guattari, I attempt to create an assemblage of a becoming-thesis. I consider potential atmospheres as âhauntingsâ, âethereal hazesâ and âvibrant ecstaciesâ which shimmer with their own agency. These are vibrant matters where I utilise the work of Stewart, Bennett and Braidotti, amongst others, to create a flatter ontology and consider all matter within this âunholy mixtureâ, including the nonhuman.
Driven by the research film that I produced alongside children, I explore the entanglements within the school environment and wonder how school may be experienced by young people. This is fuelled by a dissatisfaction with the current school agendas and the impact this has on children, and a strong moral need to care about education and childhood. Through engaging with teachers and school staff I begin the process of questioning the ordinary everyday practices, materiality and discourses that pervade schools and education.
The thesis also seeks to become atmospheric whilst resisting traditional representational models of educational research. Instead I seek an enchanting adventure through discursive and varied styles of writing. By incorporating multiple texts and writing in non-linear ways, I seek to engage with complex flows, intensities and potentialities as these constantly shift and flux. As such the reader is encouraged to negotiate an unholy mixture of traditional academic writing alongside photographs, poetry, film, personal reflective writing, and narrative story writing. These aim to act as jolts or onto-epistemological shudders hoping to mirror my own discomfort as I negotiated a doctorate in education. Both the thesis and the research aspire to be event-ful.
I end in a place better able to understand the complexities that exist around âaffective school atmospheresâ and see that the approaches of new materialisms are a fitting way to research the indeterminable. I also begin to consider how the next steps for this research involve a political turn to generate action and revolt, to consider how we might open the void to create space to change schools

Characterizing genetic diversity and creating novel gene pools in rice for trait dissection and gene function discovery
Rice diversity is the foundation for rice improvement programs. At IRRI, over 100,000 rice accessions are deposited, and intelligent use of this diversity can not only help solve current production problems but also create future production opportunities and tackle climate change challenges. To fully explore and utilize rice diversity, two ingredients are needed: 1 - the genetic blueprints of diverse rice accessions in use, 2 - plant populations with recombined genotypes allowing expression of phenotypic variation and discovery of new genes/QTLs for use in breeding programs. Sequencing of the genomes & obtaining SNP genotypes of many rice accessions is feasible due to decreasing cost of advanced DNA sequencing technologies. Coupled with the creation of populations suitable for trait dissection / phenotyping, discovery of gene functions and allelic variations causal to important agronomic traits becomes possible. This in turn will provide rich biological evidences to the rice/cereal crop genome annotation community
