As a teacher of the New South Wales Higher School Certificate Geography Syllabus in the 1970s, I became aware of problems of interpretation and implementation of syllabus documents dealing with models and theories of human aggregate behaviour. A positivistic underpinning allowed explanation in human geography to employ deductive - nomological methodology. This field study investigates a defined literature of academic geography including journals, and both secondary and tertiary documents to identify the extent and quality of nomothetic and idiographic traditions from the late 19th century to the mid 1970s. The literature prior to the late 1950s revealed a dominant regional tradition and idiographic methodology with an emphasis on description of uniqueness of areal phenomena. But underlying currents of a nomothetic nature, running parallel to this regionalidiographic tradition,exerted a noticeable challenge to gain acceptance in geographic circles. This kind of nomothetism was in the form of environmental determinism which held that physical laws operating in nature were also at work to shape and direct human societies. Environmental determinism contained generalised assertions, enjoyed some appeal, but lacked rigorous justification. Even within regional frameworks, authors used environmentally induced determinants to explain the unique character of regions. Not until the 1930s did environmental determinism lose its appeal, after which time the regional - idiographic tradition strengthened as an explanatory mode of human behaviour. Nomothetism emerged in the late 1950s in Australia in the application of models and theories explaining human behaviour. Normative theory was supported by an increased use of quantification and by the growing preference for systematic studies in geography. Neither mode of explanation exists at the total exclusion of the other; so that while nomothetism enjoyed widespread appeal in academic geography from the late 1950s, significant challenges were mounted against it because of its inadequacies as a mode of explaining human aggregate behaviour. Nomothetic explanation in human geography can be seen at the research level and in education circles. Many normative models and theories found their way into senior geography courses to the extent they promoted a systems approach. Teachers would have been aware of normative theory in geography from their university studies and teacher training courses during the late 1950s and throughout the 1960s. The tension between associated explanatory modes in systematic and regional geography becomes apparent in the analysis of the N.S.W. H.S.C. Geography Syllabus in which confusing statements raise problems for teachers interpreting and implementing this prescriptive document. Given these tensions and problems of explanation in human geography, the adoption of a critical rationalist viewpoint as propounded by Karl Popper is suggested as a possible solution for geography teachers when interpreting a syllabus such as that of the N.S.W. H.S.C. Falsification rather than verification should be the node of inquiry towards explanation of human aggregate behaviour.

Nutrients, periphyton and macroinvertebrates were sampled every two months for one year to assess the effects of treated sewage effluent on the Thredbo River and to compare changes in chemical concentrations and the invertebrate community since the introduction of nutrient removal on the Thredbo sewage treatment plant. Chemically, the impact of the effluent was minor and was reduced from levels measured before the addition of nutrient removal to the Thredbo sewage treatment plant. However, the reduction may be the result of higher flows during the study period. Biologically there was no indication of nutrient enrichment during June, August and October, with differences occurring between physically dissimilar sites irrespective of position relative to the sewage effluent inflow. Large increases in periphyton and macroinvertebrates occurred in December, February and April at both open sites and those downstream of the sewage outflow. Previous studies found increases in invertebrate abundance and richness immediately downstream of the sewage inflow, but the impact was greater and extended further downstream than found in this study. Strong correlations between total phosphorus and periphyton biomass and chlorophyll-a indicate phosphorus was a limiting nutrient. Higher periphyton biomass and chlorophyll-a at all sites during the warmer months (especially at open sites with an even cobble substratum), throughout the year, indicates light, temperature and substratum type were as important as phosphorus in controlling algal growth. Low algal biomass during the high flow month of October also indicates the importance of water velocity in controlling periphyton biomass. The structure of the macroinvertebrate community was noticeably different at sites downstream of the effluent discharge, with the exception of the most downstream site, when compared to the upstream sites. The occurrence of high macroinvertebrate numbers and species richness at sites with high periphyton growth and the strong positive correlation between invertebrate grazers and periphyton measurements shows a dependent relationship between invertebrates and periphyton growth. Therefore, the physical factors of light, temperature and substratum characteristics of particular sites in the Thredbo River, may be as important in controlling the benthic community as the levels of nutrient inputs from sewage.

Throughout their world distribution, fruit bats (Chiroptera: Pteropodidae) play an extremely important role in forest ecology through seed dispersal and pollination. However, the recognition of their role in maintaining forest ecological diversity has been largely overshadowed by the fact that fruit bats are known to cause damage to a wide variety of cultivated fruits and, as a result, significant effort is undertaken to control fruit bat numbers in areas where crop damage frequently occurs. In Australia, fruit bats of the genus Pteropus (or flying foxes) are well known for their role in destroying valuable fruit crops, particularly along the east coast from Cairns to Sydney. Historical evidence suggests that flying foxes have been culled as an orchard pest in large numbers for the past 80 years. Uncontrolled culling both on-farm and in roosts coupled with extensive habitat destruction in the past century, has resulted in noticeable declines both in flying fox distribution and local population numbers. In New South Wales, flying foxes have been 'protected' under the National Parks and Wildlife Act (1974) since 1986. From that time, fruitgrowers have been required to obtain a licence (referred to as an occupier's licence) from the National Parks and Wildlife Service (NPWS) to cull flying foxes causing damage to fruit crops. However, despite the 'protected' status of the species, flying foxes continue to be culled in large numbers as an orchard pest. An examination of the management of flying foxes in NSW, has shown that, between 1986-1992, fifteen NSW National Parks and Wildlife Service Districts issued a combined total of 616 occupier's licences to shoot flying foxes with an total allocation of over 240,000 animals. In addition, most flying foxes are culled when the female is carrying her young under wing or when the young remain in the camp but continue to be dependent on her return for survival. Further evidence on the extent of culling includes a widely distributed fruitgrower survey with responses indicating that as few as 50% of the fruitgrowers shooting flying foxes in NSW obtain the required licence from the National Parks and Wildlife Service. While the NPWS has undertaken research into the role of flying foxes in seed dispersal and pollination, management effort largely continues to focus on resolving conflicts between fruitgrowers and flying foxes primarily by issuing culling permits to fruitgrowers. At present, there is no NPWS policy on the management of flying foxes in NSW to guide the administration of the permit system. As a result, the process of issuing permits for flying foxes is largely inconsistent between NPWS Districts. The absence of comprehensive goals and objectives for the management of flying foxes has resulted in the current situation where large numbers of flying foxes are being culled both legally and illegally in the absence of any data on the impacts of unknown culling levels on local flying fox populations. The NPWS has a statutory obligation to manage flying foxes consistent with the 'protected' status of the species in NSW and several well known principles of wildlife management. However, current management of flying foxes in indicates that the Service may be in violation of the requirement to 'protect' and 'conserve' flying foxes as required under the National Parks and Wildlife Act (1974). This study recommends that licences issued to fruitgrowers to cull flying foxes be discontinued immediately and that adequate enforcement be engaged to reduce illegal shooting. This action should continue until such time that research on flying fox populations is able to demonstrate that the culling of flying foxes will not lead populations into decline. Furthermore, management effort should focus on the development of alternative strategies to reduce crop damage by flying foxes and provide incentives for growers to utilize existing control strategies such as netting.

Adventure tourism is a growing market sector worldwide including Australia. A range of research exists that examined participation in adventure tourism activities by consideration of various aspects such as socio-demographics, motivations, activity/setting preferences and involvement in the activity to understand the adventure tourist. While studies have been conducted that included several of these aspects, a holistic investigation of involvement, motivations and setting preferences together has not been conducted previously regarding adventure tourism in Australia in general and SCUBA diving in particular. Furthermore, in Australia, only limited information is available about those who participate in the adventure activity of SCUBA diving. The aim of this research is to investigate differences and similarities of involvement, motivations and setting preferences of SCUBA diving club members in Eastern Australia. In this study 294 SCUBA diving club members in New South Wales and Queensland were surveyed by utilisation of a web-based questionnaire in order to identify their involvement in SCUBA diving, socio-demographic characteristics, participation motives and setting preferences. Descriptive analysis was used to investigate the socio-demographic characteristics of divers, their motivations and setting preferences. Principal component analysis was applied on involvement variables as well as motivations to investigate the underlying constructs. Agglomerative and hierarchical cluster analyses were used to derive clusters of divers that differed in their involvement in SCUBA diving. Exact Pearson chi-square tests were conducted to test whether there were significant differences concerning sociodemographics between clusters. In addition, analyses of variance (ANOVAs) were conducted to determine differences and similarities of motivational components and setting preferences between clusters. This study found that SCUBA diving club members are a heterogeneous group regarding their involvement in SCUBA diving. Five clusters of divers emerged that differed in their involvement in SCUBA diving. While differences in socio-demographics across the different involvement clusters were revealed, they proved to be less valuable for interpretation purposes. Regarding divers� setting preferences, similar structures were observed across all clusters regardless of differences in involvement. Motivations showed a complex structure across the clusters in regard to divers� involvement in SCUBA diving. Based on the studies findings, recommendations for future research were suggested. These emphasised the need for a holistic examination of motivations and setting preferences of adventure tourists based on the concept of involvement, which would be important for theory development and segmentation of tourists. The same holistic approach would also be valuable for examining other types of tourists such as events tourists and heritage tourists to better understand tourist behaviour.

Through the implementation of a garden project in two women-centred correctional facilities in New South Wales, this thesis explores tensions between punitive and rehabilitative goals. The impacts of these tensions on the garden project and the every-day lived experience for female inmates form the basis of the research. Initially, the research looked at the rehabilitative potential of a horticultural therapy program for female inmates. This focus correlated with the holistic rehabilitative rhetoric within women’s prisons in New South Wales. Based on this, a small garden project of five months’ duration was conducted in each of the two correctional facilities over a twelve month period in 2006. Through the implementation and evaluation of this research conflicts between hierarchical, dominating systems of the penal institution and holistic, rehabilitation goals of the garden project were exposed. Utilising qualitative data analysis embedded in critical ethnography, the garden project provided a ‘key-hole’ view of these conflicts within the penal environment. The collective data from open- journaling was abstracted from raw data level through to theoretical constructs in combination with a further literature research. Foucault’s penal justice critique, Weber’s domination and Goffman’s totalitarian discourses informed the development of deeper understandings that enlightened on-going explorations in the field. As a result, theoretical understandings identified a tension within the penal environment that appeared to neutralise, fragment and corrode the intended benefits for female inmates of the garden project. This tension was identified as an intangible force, or penal phantom, representing the effects of totalisation within the penal environment. Two streams of inquiry emerged exploring the effects of the total institution on how power is exercised over female inmates and the implications upon the holistic, rehabilitative aims of the garden project. Findings from this research highlight the effects of the penal phantom upon female inmates’ lived experiences, the working realities for prison staff and how these impact upon rehabilitative programs for women in prison. The thesis concludes by examining these effects in the continued marginalisation of the current female inmate population and recommends a review of incarcerative practices that continue to entangle women within criminal justice systems. / Doctor of Philosophy (PhD)

Water and electricity are fundamentally linked. Policy reforms in both industries, however, do not appear to acknowledge the links nor consider their wider implications. This is clearly unhelpful, particularly as policy makers attempt to develop effective responses to water and energy issues, underpinned by prevailing drought conditions and impending climate change. Against this backdrop, this research has comprehensively analysed the links between water and electricity – termed water-energy nexus – in the context of New South Wales. For this purpose, this research has developed an integrated methodological framework. The philosophical guidance for the development of this framework is provided by Integral Theory, and its analytical foundations rest on a suite of research methods including historical analysis, inputoutput analysis, analysis of price elasticities, and long-term scenario analysis. This research suggests that the historical and inextricable links between water and electricity, in the absence of integrated policies, has given rise to water-energy trade-offs. In the electricity industry, water-intensive coal-fired power stations that dominate base-load capacity in the National Electricity Market has resulted in intra- and inter-jurisdictional water sharing tradeoffs. Intermediate and peak demand technologies, suchas gas-fired, cogeneration and renewables, however, would significantly reduce the industry’s water consumption and carbon emissions. Drought and climate change adaptation responses in the water industry are likely to further increase electricity demand andpotentially contribute to climate change, due to policies that encourage investment in energy-intensive technologies, such as desalination, advanced wastewater treatment and rainwater tanks. Increasing electricity costs due to water shortages and the introduction of emissions trading will futher increase water and electricity prices for end users. Demand management strategies in both industries will assist in curbing price increases, however, their effectiveness is lessened by investment in water- and energy-intensive technologies in both industries. The analysis also demonstrates that strategies to reduce water and electricity consumption of ‘other’ production sectors in New South Wales is overwhelmingly dependent on how deeply a particular sector is embedded in the economy, in terms of its contribution to economic output, income generation and employment growth. Regulation, demand management programs, and water pricing policies, for example, that reduce the water and energy intensity of agriculture and key manufacturing sectors are likely to benefit the wider economy and the Environment. The future implications of the water-energy nexus are examined through long-term scenario analysis for New South Wales for 2031. The analysis demonstrates how policy decisions shape the domain for making philosophical choices by society - in terms of the balance between relying on alternative technologies and market arrangements, with differing implications for water and electricity use, and for instigating behavioural change. Based on these findings, this research puts forward a range of recommendations, essentially arguing for reorienting existing institutional arrangements, government measures and industry activities in a way that would encourage integration between the water and energy policies. Although the context of this research is New South Wales, the findings are equally relevant for other Australian states, which share the same national water and energy policy frameworks. Further, the concepts and frameworks developed in this research are also of value to other countries and regions that are faced with the task of designing appropriate policy responses to redress their water and energy challenges.

Includes bibliographies. This thesis describes an irrigation experiment established on Vitis vinifera cv. Shiraz in a mature vineyard in the Australian Murray-Darling basin. It concentrates on the relationship between the timing of the water deficit and the depth of irrigation applied and the difference in berry weight between different irrigation treatments. The study includes a polynomial equation which describes the relation between growing degree days and °Brix. A two phase linear model is used to describe the change in red-free glycosyl-glucose (G-G).

Given the urgency of climate-change and the speed and scale of the structural transition to a low-carbon economy, there is a critical need for research that accelerates the diffusion of learning in the field of employment and workforce planning. While efforts to align workforce development and planning with the introduction of green policies are rapidly intensifying and maturing, there are gaps in coherence. The transition to sustainable economies involves significant shifts in employment, including application and use of skills and workplace practices. New occupations are emerging and existing occupations are being greened at a rapid rate (Globe Foundation, 2010 a; ILO, 2011, pg. 4; 2012: OECD, 2013 pg. 47). Keeping equilibrium in employment while climate-change forecasts and technological innovations are rapidly evolving is a growing challenge for workforce planning and policy. This is also a ‘rate of change’ problem, and it needs to be better understood if governments are to provide leadership, adapt more quickly, and provide continuous high levels of services to citizens while maintaining strong economies. Governments that understand this will be at the forefront of mitigation and adaptation efforts (OECD, 2012 a, b). But how should that challenge be met? This study tackles that question, seeking to clarify how workforce development and planning can be directed toward improving employment prospects and reducing employment dislocations as the planet changes around us in the face of a changing climate. The implications of the findings are outlined and recommendations are then made as to how labour policies and workforce development and planning measures can best be targeted and integrated into the larger green policy framework to improve coherence of policies, institutional and organizational capacity and data capability. / Graduate
