Barriers to care for depressed older people : perceptions of aged care among medical professionals

The current study evaluated barriers to detection of depression among older people. Focus groups were conducted with 21 professional carers, 4 nurses, 10 general practitioners, and 7 aged care managers. The results demonstrated that care for older people is primarily focused on physical care. Further, staff resources, a lack of continuity of care, multiple co-morbidities, reluctance by older people to discuss depression, negative attitudes among carers, as well as a lack of skills all contributed to a failure to detect and treat depression. The implications of these findings for training programs for professional carers are discussed.

Using input-output data in life cycle inventory analysis

The impacts on the environment from human activities are of increasing concern. The need to consider the reduction in energy consumption is of particular interest, especially in the construction and operation of buildings, which accounts for between 30 and 40% of Australia's national energy consumption. Much past and more recent emphasis has been placed on methods for reducing the energy consumed in the operation of buildings. With the energy embodied in these buildings having been shown to account for an equally large proportion of a building's life cycle energy consumption, there is a need to look at ways of reducing the embodied energy of buildings and related products. Life cycle assessment (LCA) is considered to be the most appropriate tool for assessing the life cycle energy consumption of buildings and their products. The life cycle inventory analysis (LCIA) step of a LCA, where an inventory of material and energy inputs is gathered, may currently suffer from several limitations, mainly concerned with the use of incomplete and unreliable data sources and LCIA methods. These traditional methods of LCIA include process-based and input-output-based LCIA. Process-based LCIA uses process specific data, whilst input-output-based LCIA uses data produced from an analysis of the flow of goods and services between sectors of the Australian economy, also known as input-output data. With the incompleteness and unreliability of these two respective methods in mind, hybrid LCIA methods have been developed to minimise the errors associated with traditional LCIA methods, combining both process and input-output data. Hybrid LCIA methods based on process data have shown to be incomplete. Hybrid LCIA methods based on input-output data involve substituting available process data into the input-output model minimising the errors associated with process-based hybrid LCIA methods. However, until now, this LCIA method had not been tested for its level of completeness and reliability. The aim of this study was to assess the reliability and completeness of hybrid life cycle inventory analysis, as applied to the Australian construction industry. A range of case studies were selected in order to apply the input-output-based hybrid LCIA method and evaluate the subsequent results as obtained from each case study. These case studies included buildings: two commercial office buildings, two residential buildings, a recreational building; and building related products: a solar hot water system, a building integrated photovoltaic system and a washing machine. The range of building types and products selected assisted in testing the input-output-based hybrid LCIA method for its applicability across a wide range of product types. The input-output-based hybrid LCIA method was applied to each of the selected case studies in order to obtain their respective embodied energy results. These results were then evaluated with the use of a number of evaluation methods. These evaluation methods included an analysis of the difference between the process-based and input-output-based hybrid LCIA results as an evaluation of the completeness of the process-based LCIA method. The second method of evaluation used was a comparison between equivalent process and input-output values used in the input-output-based hybrid LCIA method as a measure of reliability. It was found that the results from a typical process-based LCIA and process-based hybrid LCIA have a large gap when compared to input-output-based hybrid LCIA results (up to 80%). This gap has shown that the currently available quantity of process data in Australia is insufficient. The comparison between equivalent process-based and input-output-based LCIA values showed that the input-output data does not provide a reliable representation of the equivalent process values, for material energy intensities, material inputs and whole products. Therefore, the use of input-output data to account for inadequate or missing process data is not reliable. However, as there is currently no other method for filling the gaps in traditional process-based LCIA, and as input-output data is considered to be more complete than process data, and the errors may be somewhat lower, using input-output data to fill the gaps in traditional process-based LCIA appears to be better than not using any data at all. The input-output-based hybrid LCIA method evaluated in this study has shown to be the most sophisticated and complete currently available LCIA method for assessing the environmental impacts associated with buildings and building related products. This finding is significant as the construction and operation of buildings accounts for a large proportion of national energy consumption. The use of the input-output-based hybrid LCIA method for products other than those related to the Australian construction industry may be appropriate, especially if the material inputs of the product being assessed are similar to those typically used in the construction industry. The input-output-based hybrid LCIA method has been used to correct some of the errors and limitations associated with previous LCIA methods, without the introduction of any new errors. Improvements in current input-output models are also needed, particularly to account for the inclusion of capital equipment inputs (i.e. the energy required to manufacture the machinery and other equipment used in the production of building materials, products etc.). Although further improvements in the quantity of currently available process data are also needed, this study has shown that with the current available embodied energy data for LCIA, the input-output-based hybrid LCIA appears to provide the most reliable and complete method for use in assessing the environmental impacts of the Australian construction industry.

Critical reflections on professional education for the environment

Evidence exists to suggest that in Australia many environmental issues remain unresolved even though the community has apparently become more environmentally aware. Although universities have undertaken responsibility to educate future environmental professionals to address this concern, there are numerous tensions underpinning professional environmental education. This folio explores my perceptions of these tensions and their effect on my professional practice as an academic. I refer to this as the relationships among theories and practices experienced in my work. Four perspectives are taken in this research as I appraise professional environmental education. This Dissertation (Vol. 1) focuses on views informing my professional environmental education, inclusive of my own reflexivity. From interviews with students, academics, professionals and environmentalists, and other sources of information, I consider various tensions arising from what I regard as dehumanising social and political forces. The conventional elite and authoritative roles for universities and professionals dominate most participants' understanding of professional activities. Professional practices often endorse these conventions. Juxtaposed to this authoritative view of professional education, and prescribing a different interpretation for professional practice, is my theoretical position informed by criticality and a need to challenge the status quo. I suggest that Leopold's The Land Ethic is an exemplar of criticality and a suitable basis for examining professional environmental education. The Land Ethic is used as a foundation to my thesis because it encapsulates suitable arguments to examine ideologies supportive of my understanding of professional environmental education. My thesis investigates the nature of participants' (including my own) understanding of their land ethic or land ethics suggesting that interpretations of 'place' provide an emotional and ethical appreciation of the land. I suggest that 'place', as a culturally derived construct, is central to the concept of a land ethic or land ethics, and a characteristic of an environmental ethic or ethics. To incorporate these different perspectives into professional environmental education perhaps land could be viewed, not just as a 'client' as in Schön's (1983) reflective contract, but expanded so that professionals form ethical partnerships with the land, which implies a greater equity between roles and responsibilities. This perspective challenges elite interpretations of the roles for environmental professionals by asking them to be advocates for their land, and to work with the land. Searching for my own land ethic or land ethics has promoted a discourse that encompasses a language of possibility and opportunity. This language of possibility and opportunity stands in contrast to the constraining language of reproduction that has promoted stasis. My reflexivity, a holistic and ecological view that in this thesis is an expression of my searching for a land ethic or land ethics, has encouraged me to develop critical and ethical questions to challenge my professional environmental education practice. As such the process of theorising about my theory and practice has been personally transformative as it encourages my development as a 'critical person'. Elective 1 (Vol. 2 ) reviews public information promoting a selected range of Australian environmental courses. Analysis demonstrates environmental courses are mainly technocratic, promoting technical-scientific and vocational perspectives. This orientation, I consider, is aligned to an emerging corporate agenda as universities attempt to be more accountable to the government within a competitive market dominated by economic interests. Elective 2 (Vol. 2 ) considers the providers of professional environmental education where I explore a diversity of tensions undermining current academic life found in many Australian universities. I suggest that corporatisation and vocationalisation dominate university culture to such an extent that any examination of professional environmental education is prejudiced. Professional environmental education appears to be biased toward maintaining the status quo. My conclusion is that professional environmental education does not promote graduates as 'critical persons' (Barnett 1997), and this may affect graduates' understandings of the purpose and aspirations of environmental professionalism. I suggest that elite and technical understandings of professionalism may affect the professionals' ability to implement environmental policy. Australia has an admirable record of developing environmental policy. However, public concern about a lack of resolution for many environmental issues suggests that professionals may be struggling to successfully implement policy in any meaningful way. Such challenges for environmental professionals may be a result of a professional environmental education that does not engage graduates within ideas that professional practice may require community participation and collaboration as key themes. Elective 3 (Vol. 2) is a case study investigating the development of conservation policies by the Ballarat community. The case demonstrates how the dominant social paradigm informs community views about environmental issues emphasising a technical emphasis and hierarchical arrangements of power and authority between local government and the community. The community view appears to be that environmental action should be mainly individualistic and behaviourist, which I suggest may have resulted from a technical framework for environmental knowledge. The community view of environmental issues resonates with the dominant view promoted by professional environmental education in most universities. In conclusion, my thesis is a representation of my challenges to critically engage in possible relationships among theories, practices and circumstances in my workplace, with a view to addressing what I perceive as a 'gap' between my own theory and practice. The motivation for this critical examination is to question the purpose of my professional environmental education practice in relation to the challenges of my emergent environmental ideology. The difficulty of promoting my critical theorising in a traditional small science faculty, within a corporate university, with my scientific background, is acknowledged. Nevertheless, based on my own experiences, I recommend that academics involved in professional environmental education should be encouraged to explore relationships between their own theories and practices in their own professional settings. I suggest that the search for a land ethic or land ethics, and one's 'place' in the 'land', can be an effective platform for this process.

Burnout and the conservation of resources theory

This thesis examines, within the framework of the Conservation of Resources Theory, the development of burnout in a sample of Victorian nurses over a nine-month period. Results showed that work characteristics demonstrated different associations with burnout and that COR theory was partially successful as an explanatory framework.

Recovery of estuaries following disturbance by pollutants

The recovery of a heavily polluted estuary was assessed by comparing the structure of its intertidal community with six other estuaries. Results indicated that some recovery had occurred, however improvements in the study methodology were required to further clarify the ecological status of the creek.

Measuring dairy farm performance

To fully consider production impacts, this thesis adopts a systems perspective and uses a biophysical model, DairyMod, to measure the interactions between system components and gauge the environmental impact of dairy farming arising from nitrogen use. Performance from the perspective of both the individual farmer and society is examined.

Small mammals in a fragmented landscape

Small mammals displayed contrasting patterns of occurence in forest fragments. Population studies revealed that key processes responsible for survival in habitat patches include demographic flexibility and the movement of individuals between patches. Combining pattern- and process-based approaches provides a more complete understanding of fauna in modified landscapes.

Ecology of mistletoe parasitism in rural landscapes

This study examined the distribution of native mistletoes in agricultural landscapes. Mistletoes occur in all types of wooded habitat, and provide resources for many species. Landscape structure, particularly the overall extent of tree cover, is vital for conserving mistletoes. Their future status depends on effective management across different land tenures.

Stress, health, work and family in the Australian hospitality industry

Hospitality was found to be a potentially high stress occupation. Potential work and family stressors, symptoms, affective factors, coping strategies and resources were identified. A stress-psychological health model was developed. Possible implications for stress research, measurement, prevention and management in the hospitality industry were proposed.

Urban streetscape bryophytes and heavy metals

This thesis presents the first large scale examination of urban bryophytes in Australia in terms of species distribution, screening as hyperaccumulators and use as biomonitors. It provides baseline data to allow future comparison of the distribution of urban bryoflora with respect to arsenic and the associated contribution of cadmium, copper, zinc and lead.
