This study investigates the development of services and treatment modalities for the mentally ill of Western Australia from a nursing perspective. The thesis moves from the influences of Europe to focus on the emergence of services for the mentally ill in Western Australia. In particular the process of change that has occurred in the treatment of Western Australia’s mentally ill from colonisation to the end of the 1980s is considered. The study has a central focus on nursing care, and how nursing has adapted to changes in treatment modalities for mental illness as well as emerging government policy, fiscal restraint and community beliefs concerning mental illness. Through exploration of the role and care provided by mental health nurses and a description of the environment where this care was administered, an insight into how the mentally ill were perceived and treated is gained.

The Sakmarian (Cisuralian, Permian) Fossil Cliff Member of the Holmwood Shale is situated in the northern Perth Basin, Western Australia, and consists of alternating beds of shale and silty calcarenite forming three parasequences. Within this member a diverse fauna of ostracodes and foraminifera are present. During the Cisuralian the northern Perth Basin formed part of the Gondwanan supercontinent and was linked to Greater India via an epeiric sea that opened to the north. The ostracode fauna is restricted to the calcareous beds of the member and consists of a diverse benthic fauna comprising 31 new species and 13 previously recorded species. Species from the Healdioidea, Bairdioidea, Youngielloidea, and Thlipsuroidea dominate the assemblage and suggest a normal-marine environment during the period represented by the calcareous beds, with an overall shallowing trend up the sequence. The fauna shows some similarity to faunas from the Tethyan deposits of North America and the Boreal deposits of Russia during the Late Carboniferous and Cisuralian. Twenty-eight species of foraminifera were recorded from the Fossil Cliff Member and underlying Holmwood Shale and comprise two distinct faunas, an agglutinated benthic foraminiferal fauna found within the shale beds and a calcareous benthic foraminiferal fauna present in the calcarenite units. The agglutinated foraminifera are inferred to represent deposition in dysoxic to suboxic (0.1-1.5 mL/LO2;), poorly circulated bottom waters below wave base. The calcareous foraminifera are inferred to represent deposition in normal-marine conditions. Both foraminiferal assemblages show a shallowing trend in their distribution that matches the trend identified in the ostracode fauna. Based upon the palaeoecology of the ostracode and foraminiferal faunas, the depositional environment for the Fossil Cliff Member is inferred to have been within shallow water in an epeiric basin during an overall marine regression that is overprinted by eustatic and isostatic oscillations resulting from deglaciation that occurred during the early Sakmarian (Cisuralian). These sea-level oscillations raised and lowered the oxic surface waters of the epeiric sea above and below the substrate resulting in a sparse agglutinated foraminiferal fauna or an abundant and diverse ostracode and calcareous foraminiferal fauna respectively.

Michael Fullan (1991) commented that little was known about how students viewed educational change, as no one had thought to ask them. By 2004 there was a small but growing literature seeking the views of students on a range of issues associated with schooling. This thesis presents the findings and analysis of a study of students’ perceptions of educational change. Much educational change involves shifts in power and responsibilities between the different actors, such as governments, school administrators, teachers, parents, the community and students. Despite widespread interest in educational change it is usually the macro-level policy elite who exert the most influence, using their power, privilege and status in order to propagate particular versions of schooling; students continue to be the ‘objects’ of policy initiatives, submerged in what Freire referred to as a ‘culture of silence’. Students are frequently excluded as participants in both the process and decision making phases of change. This research was based on exploring the exclusion of students from the processes of change in schools, resulting from a top-down policy initiative by the State department of education in WA, the Local Area Education Planning (LAEP) Framework. How policy is defined and acted on is explored, and the roles students could have, but often do not, are highlighted. An eclectic hybrid conceptual framework drawing on both critical theory and a postmodern policy cycle approach was used to analyse the LAEP Framework policy processes and students’ perceptions of the changes that ensued. The research comprised in-depth case studies of three schools undergoing substantial educational restructuring as the result of the macro-level LAEP Framework policy in the State of WA. Key elements of the policy were school amalgamations, closures and the creation of Middle Schools. Data collection methods included focus group and semi-structured interviews with students from the three schools, as well as document analysis, staff interviews and field notes. The research found that students were very perceptive about educational change, that they were deeply impacted by educational change and that they wanted to participate in restructuring agendas. Several meta-level themes emerged from the students’ ‘voices’, including issues associated with disempowerment, and competing social justice and economic discourses. The findings foreground the often messy and contradictory tensions evident in policy processes. The thesis concluded by developing theory on ways in which students could be included meaningfully as participants in educational change

[Truncated abstract] Introduction, Little is known about the prevalence of post-course diving injuries amongst Western Australian recreational divers, nor is it known which risk factors affect the Western Australian diver’s likelihood of sustaining a diving injury. Objective, The aim of this study was to measure the prevalence of diving-related injuries amongst Western Australians with varying experience since certification as entry-level divers within Western Australia (WA). Specifically, the study compared divers’ experience, behaviour and equipment with their diving injury history. It was hypothesised that diving experience has an effect upon the likelihood of a certified diver suffering any of the diving injuries most commonly reported amongst international diving populations. In addition, the strength of association between diving injuries and other potential risk factors was measured amongst certified Western Australian divers. Methods, A cross sectional survey of Western Australians, whom had completed a recognized entry-level recreational scuba diving course within WA, formed the basis of the study. Diver training facilities within WA posted a four-page questionnaire to divers they had trained to entry-level within the previous six years. The self-administered questionnaire collected data describing the divers’ post-course participation in scuba diving, injury prevalence during the last year, demographic characteristics and prevalence of known or hypothesized diving injury risk factors ... Conclusion, In this study diving experience, measured by the number of dives made during the previous year and the total number of dives made since certification, has not been found associated with the likelihood of reporting having suffered at least one diving injury of any type whilst diving during the previous year. Whilst the limited response rate and self-reporting methodology threaten the validity of the findings of this study, the findings improve our understanding of the type of diving injuries commonly suffered by divers, and of which risk factors are associated with a diver’s likelihood of suffering a diving related injury within WA. These findings may assist the design of further diving injury research, ultimately leading to the design of diving safety interventions aimed at reducing the prevalence of diving injuries amongst Western Australian recreational divers.

The main hypothesis tested in this thesis was that poor animal production from saltbush pastures is due to the negative effects of high sodium chloride (NaCl) and potassium chloride (KCl) on the ruminal environment, and subsequent effects on microbial populations and products of rumen fermentation. This main hypothesis was tested in two experiments. In the first experiment (Chapter Four) the effects of saltbush and a formulated high-salt diet on the ruminal environment and microbial populations were measured over 24-hours following feeding. Feeding both the saltbush and high-salt diet increased the salinity of the rumen fluid, but the formulated high-salt diet caused a decrease in ruminal pH while the saltbush caused an increase. This resulted in differences in the composition of the ruminal microbial populations between the sheep fed different diets. In the second experiment (Chapter Five) the effects of saltbush and a formulated highsalt diet on rumen fermentation were measured. Sheep fed saltbush had inefficient rumen fermentation and this was only partially explained by the high salt content of the diet. Diets containing high levels of NaCl and KCl provided low levels of net energy to sheep, but sheep fed saltbush lost more energy as methane and faecal energy compared to sheep fed the formulated high-salt diet. Inefficient rumen fermentation could help to explain poor animal production from saltbush pastures. Energy supplements such as barley grain can improve the value of saltbush pastures as feed for sheep, but there is no information on how much supplement is required. A third experiment (Chapter Six) was designed to test the hypothesis that there would be an optimal amount of barley required to improve the efficiency of rumen fermentation in sheep fed saltbush. Barley and straw were combined in a pellet and substituted for saltbush at 0, 20, 40, 60, 80 and 100% of the maintenance ration. Feeding barley and straw improved the efficiency of rumen fermentation in sheep fed saltbush, with an optimal level of supplementation at 60% of the maintenance diet. This is likely to be lower (approximately 20% of maintenance) if barley is fed without straw.
