Full textAbstract:
The primary aim of this research was to find predictors of psycho-social adjustment of Polish immigrants to Sydney, Australia. There were two sets of independent variables considered: i) personal characteristics, including: intelligence, extraversion, neuroticism, style of attribution and self-acceptance and ii) demographic information, consisted of: age, gender, length of residence, marital status, number of children, educational level, yearly income, immigration status (dependent vs. independent immigration) and residential status. The dependent variables were social (adaptation and assimilation) and psychological adjustment. The hypotheses tested in the study were that each of these personal and demographic characteristics would be associated with adaptation and/or assimilation, and psychological well-being. The two samples (both studies) were composed of more than 200 first generation Polish immigrants who arrived in Australia after 1980. No significant gender differences were found. The internal consistency and principal components structure of Adaptation and Assimilation were examined, and the measures were refined. There were employed standard measurements (i.e. GHQ, BDI, BAI, EPI, ASQ, Raven Matrices and WAIS-Vocabulary) and newly developed measures (i.e. the Social Adjustment Scale and the Self-Acceptance Questionnaire). The general results suggested that psycho-social adjustment was best predicted by three pre-arrival characteristics (extraversion, education and self-acceptance), and post-arrival employment status and length of residence. There were, however, some differences in regard to the particular aspects of psycho-social adjustment. Better adaptation was meaningfully related to employment (income) and education in Study 1, and self-acceptance, employment and extraversion in Study 2; better assimilation seemed to be significantly predicted by education, age of arrival and length of residence (Study 1), and self-acceptance, extraversion, education and age of arrival (Study 2). Psychological [mal]adjustment was best indicated by globality and stability in attributing negative events (Study 1), lower self-acceptance and lack of employment status (Study 2).

Full textAbstract:
[Truncated abstract] During the last fifty years mathematical models of catchment hydrology have been widely developed and used for hydrologic forecasting, design and water resources management. Most of these models need large numbers of parameters to represent the flow generation process. The model parameters are estimated through calibration techniques and often lead to ‘unrealistic’ values due to structural error in the model formulations. This thesis presents a new strategy for developing catchment hydrology models for representing streamflow and salinity generation processes. The strategy seeks to ‘learn from data’ in order to specify a conceptual framework that is appropriate for the particular space and time scale under consideration. Initially, the conceptual framework is developed by considering large space and time scales. The space and time scales are then progressively reduced and conceptual model complexity systematically increased until ultimately, an adequate simulation of daily streamflow and salinity is achieved. This strategy leads to identification of a few key physically meaningful parameters, most of which can be estimated a priori and with minimal or no calibration. Initially, the annual streamflow data from ten experimental catchments (control and cleared for agriculture) were analysed. The streamflow increased in two phases: (i) immediately after clearing due to reduced evapotranspiration, and (ii) through an increase in stream zone saturated area. The annual evapotranspiration losses from native vegetation and pasture, the ‘excess’ water (resulting from reduced transpiration after land use change), runoff and deep storage were estimated by a simple water balance model. The model parameters are obtained a priori without calibration. The annual model was then elaborated by analysing the monthly rainfall-runoff, groundwater and soil moisture data from four experimental catchments. Ernies (control, fully forested) and Lemon (53% cleared) catchments are located in zone with a mean annual rainfall of 725 mm. Salmon (control, fully forested) and Wights (100% cleared) are located in zone with mean annual rainfall of 1125 mm. Groundwater levels rose and the stream zone saturated area increased significantly after clearing. From analysis of this data it was evident that at a monthly time step the conceptual model framework needed to include a systematic gain/loss to storage component in order to adequately describe the observed lags between peak monthly rainfall and runoff.

Full textAbstract:
Using grounded theory methodology and interviews, this study explores the experiences of second generation displaced persons from Polish and German background who grew up in Australia post-World War Two. Many of this cohort, from their early years, experienced: limited social, economic, and cultural capital; assimilation; and lived in war-affected families. It was, therefore, important that they became resilient and adaptable. Emergent from the research are the theoretical concepts of “parallel lives” and “circle of protection”.

Full textAbstract:
Electricity is the cornerstone of modern life. It is essential to economic stability and growth, jobs and improved living standards. Electricity is also the fundamental ingredient for a dignified life; it is the source of such basic human requirements as cooked food, a comfortable living temperature and essential health care. For these reasons, it is unimaginable that today's economies could function without electricity and the modern energy services that it delivers. Somewhat ironically, however, the current approach to electricity generation also contributes to two of the gravest and most persistent problems threatening the livelihood of humans. These problems are anthropogenic climate change and sustained human poverty.
To address these challenges, the global electricity sector must reduce its reliance on fossil fuel sources. In this context, the object of this research is twofold. Initially it is to consider the design of the Renewable Energy (Electricity) Act 2000 (Cth) (Renewable Electricity Act), which represents Australia's primary regulatory approach to increase the production of renewable sourced electricity. This analysis is conducted by reference to the regulatory models that exist in Germany and Great Britain. Within this context, this thesis then evaluates whether the Renewable Electricity Act is designed effectively to contribute to a more sustainable and dignified electricity generation sector in Australia.
On the basis of the appraisal of the Renewable Electricity Act, this thesis contends that while certain aspects of the regulatory regime have merit, ultimately its design does not represent an effective and coherent regulatory approach to increase the production of renewable sourced electricity. In this regard, this thesis proposes a number of recommendations to reform the existing regime. These recommendations are not intended to provide instantaneous or simple solutions to the current regulatory regime. Instead, the purpose of these recommendations is to establish the legal foundations for an effective regulatory regime that is designed to increase the production of renewable sourced electricity in Australia in order to contribute to a more sustainable and dignified approach to electricity production.

Full textAbstract:
Rapid and significant reductions in the costs of solar photovoltaic technology and considerable rises in grid electricity prices have prompted the question: When will it be cost effective for consumers to disconnect from central grids for distributed generation in Australia?
This report seeks to give insight into this question by comparing standalone solar PV and storage system levelised cost forecasts to centralised grid electricity price forecasts. The report also, based on literature research, discusses the impacts and issues associated with increased distributed generation in general on the current electricity market and incumbent utilities.
The future costs of Photovoltaic (PV) with storage systems were forecast using single factor experience curves. The Homer energy modelling software was then used to optimise the systems and calculate the levelised cost of electricity (LCOE) for each scenario. Future electricity prices were estimated based on data from AEMOc (2012). The analysis treats the two as independent variables; therefore, it does not account for interrelationships that exist in reality. Consequently, the results are best viewed as a range of possible outcomes that, given the breadth of the range covered, are likely to include the actual outcome.
The analysis focuses on small consumers such as residential, and small to medium businesses, because it was thought that this consumer group was most likely to have premises suitable for a PV system that met most of their electricity consumption. This consumer group consumes a significant amount of Australia’s total electricity: estimated at between 30 and 50 percent based on data from IEA (2012) and AEMO (2010).
The analysis considered multiple scenarios: grid electricity against standalone PV with storage, and grid electricity against 50 percent and 75 percent PV penetration levels. All scenarios considered low electricity price states with an average price of $0.30/kWh and high price states with an average price of $0.40/kWh.
The analysis revealed that solar PV with storage could be competitive with the grid in supplying 50 to 75 percent of a small consumer’s electricity demand within the short term (<5 years), and on a standalone basis in the medium term (<10 years). It is expected that this will lead to reduced demand for grid electricity, falling revenues for incumbent utilities and, therefore, a negative impact on their profitability. As a result of falling demand, network service providers will likely need to raise per unit charges in order to recover the revenue required to meet their regulated return on asset base. This will drive electricity prices higher, thus increasing the competitiveness of distributed generation (DG), and other technologies such as energy efficiency and energy management for that matter. In turn, consumers’ demand for grid electricity will reduce, and the uptake of DG will increase, which will reduce the networks’ ability to recover revenue further. Because of falling demand, generators face lower wholesale prices, compressed margins, and the risk of stranded assets. This scenario of falling demand and rising prices is commonly referred in the literature as the ‘death spiral’ (Kind, 2013; Nelson & Simshauser, 2012; Newbury, 2013; Severance, 2011).
A review of literature identified DG as being potentially disruptive to the existing electricity market. Based on case studies of disruptive technologies in other industries, DG can be expected to cause significant market changes and create significant risks for incumbents, especially those in monopoly situations. Interview based research in Australia and Germany suggests that most incumbent electricity utilities are not well prepared to handle competition from DG, are slow in realising the threat to their business model, and are failing to see the market opportunities.
Government intervention is likely given the significant amount of recent government and industry reports on the topic; this will influence the uptake of DG technologies, and subsequently the time it will take for them to become competitive at high penetration levels or on a standalone basis. Some recommended changes such as removal of price regulation, time of use pricing, demand pricing, and integrated network planning that includes DG would tend to increase the uptake of DG technologies, subsequently driving down DG costs faster. However, other recommended changes such as high fixed charges, additional fixed charges specifically for PV owners, and penetration limitations by network service providers would act to slow the uptake and cost reductions of DG. While intervention is likely, what intervention is difficult to say with confidence at this point in time given that the recent change of Federal Government has put in doubt the relevance of existing government literature on the topic. In addition, the crowded energy policy space often changes policy significantly between white/inquiry paper and enactment.

Full textAbstract:
This thesis contributes to the development of thermochemical liquefaction as a process for biofuel production. This study investigated residues from sugarcane, energy crops and algae. The potential amount of energy from biomass resources were investigated for each region in Australia. The work was at a larger laboratory scale than other workers which allowed more detailed characterisation of each sample and more thorough investigation of the fuels. Importantly, various bio-crude oils were successfully generated which were comparable with heavy fossil fuel based oils by changing only the processing conditions and without catalytic upgrading.

Full textAbstract:
My thesis explores the social construction of identity of 50 second generation migrant-Australian women aged 17 to 28 years using a qualitative methodology. I conducted in-depth semi-structured interviews with 25 women from Latin American backgrounds and 25 women from Turkish backgrounds. My study investigated the intersections of ethnicity, gender, sexuality and nationality. I found that the Latin women constructed their ethnic culture in reference to their country-of-origin traditions, and that they also identified with a pan-ethnic Latin culture that included migrants from other South and Central America countries. I found that the Turkish women constructed Turkish culture in reference to their religious practices, and they saw themselves as �Muslim-Turks� who identified with an Islamic pan-ethnic culture that included Muslim migrants from different national backgrounds. The women in both groups drew upon Anglo-Australian culture when it came to their gender and sexuality constructions. The Latin and Turkish women did not see themselves as �typical� women from their migrant communities. Instead, their sense of femininity was informed by what they saw as Australian egalitarianism. The women in both groups saw Anglo-Australians� gender relationships as an ideal, and as one woman said of Anglo-Australians, �how much more equal can you can get?� The women�s social construction of the nation was equally influenced by multiculturalism and an Anglo-Australian identity. They highly valued their Australian citizenship and felt positive about their lives in Australia. At the same time, they had faced ongoing racism and they reported that other people judged their Australian identities through racial characteristics. One woman said that in order for people to be accepted as Australian, �you have to be Anglo and not look like me�. Despite this sense of social exclusion, the majority of my sample held hybrid migrant-Australian identities. I develop a threefold typology of the women�s identities, and I found that 13 women did not see themselves as Australian, 36 women saw themselves as partly-Australian, and one woman held an exclusively Australian identity. I argue that narratives of multiculturalism and Anglo-Australian identity influenced the women�s social construction of identity. Their belief that Australian identity was multicultural was at odds with their experiences of racism and their own self identities, and so I examine the women�s beliefs in reference to an �ideology of multiculturalism�. This ideology supported the women�s contribution to the nation as second generation migrants, and ultimately, they expressed an unwavering support for Australian multiculturalism.

Full textAbstract:
With an increasing proportion of older people in the Australian population and increasing health and longevity, paid work after the age of 65 years may become an option or a necessity in the future. The focus of this research is on Australian women of the baby boom generation, their working futures, and the work-retirement decision. This is explored both from the viewpoint of women and from a social policy perspective. The research draws on Considine�s model of public policy, futures studies, and Beck�s concept of risk society. The research comprises three studies. Using focus group research, Study 1 explored the views of Australian women of the baby boom generation on work after the age of 65 years. Study 2 aimed to explore current thinking on the research topic in Australia and overseas. Computer-mediated communication involving an Internet website and four scenarios for the year 2020 were used for this study. Study 3 consists of the analysis of quantitative data from the Healthy Retirement Project, focusing on attitudes towards retirement, retirement plans, and the preferred and expected age of retirement. The importance of choice and a work � life balance emerged throughout the research. Women in high-status occupations were found to be more likely to be open to the option of continuing paid work beyond age 65 than women in low-status jobs. However, the women were equally likely to embrace future volunteering. The research findings suggest that policies for an ageing female workforce should be based on the values of inclusiveness, fairness, self-determination, and social justice, and address issues of workplace flexibility, equality in the workplace, recognition for unpaid community and caring work, opportunities for life-long learning, complexity and inequities of the superannuation system, and planning for retirement. Further, providing a guaranteed minimum income for all Australians should be explored as a viable alternative to the current social security system.

Full textAbstract:
The Northern Carnarvon Basin is the richest petroleum province in Australia. About 50 gas/condensate and oil fields, associated mainly with Jurassic source rocks, have been discovered in the sub-basins and on the Rankin Platform since 1964. The basin is located at the southern end of the North West Shelf of Australia. It can be mainly subdivided into the Exmouth, Barrow, Dampier and Beagle Sub-basins, the Rankin Platform and Exmouth Plateau. The sub-basins are rift-related grabens and half-grabens developed during the Jurassic to the earliest Cretaceous and contain over 10 kilometres of Mesozoic and Cainozoic sedimentary rocks, among which are several thousand meters of Jurassic rocks. The formations of the Jurassic and the lower part of the Barrow Group of Early Cretaceous age in the sub-basins of the Northern Carnarvon Basin were found to be overpressured with excess pressures of 5-29 MPa at depths of 2900-3600 m indicated by repeat formation tests (RFTs) and drill stem tests (DSTs). The characteristics of organic matter, thermal history and thermal maturity, pressure seal and overpressure evolution in the sub-basins are crucial to a proper understanding of the nature and dynamic processes of hydrocarbon generation and migration in the basin. Based on organic geochemical data, the important source rocks in the basin are Jurassic organic-rich fine-grained rocks including the Murat Siltstone, the rift-related Athol Formation and Dingo Claystone. The Mungaroo Formation of the Middle-Upper Triassic contains gas-generating source rocks. These formations recognised to be organic rich based on 1256 values of the total organic carbon content (TOC, %) from 17 wells. Average TOC values (calculated from samples with TOC < 15 %) are about 2.19 % in the Mungaroo Formation, about 2.09 % in the Murat Siltstone and about 1.74 % in the Athol Formation and Dingo Claystone.Data from kerogen element analysis, Rock-Eval pyrolysis, visual kerogen composition and some biomarkers have been used to evaluate the kerogen type in the basin. It appears that type III kerogen is the dominant organic-matter type in the Triassic and Jurassic source rocks, while the Dingo Claystone may contain some oil-prone organic matter. The vitrinite reflectance (Ro) data in some wells of the Northern Carnarvon Basin are anomalously low. As a major thermal maturity indicator, the anomalously low Ro data seriously hinder the assessment of thermal maturity in the basin. This study differs from other studies in that it has paid more attention to Rock-Eval Tmax data. Therefore, problems affecting Tmax data in evaluating thermal maturity were investigated. A case study of contaminated Rock-Eval data in Bambra-2 and thermal modelling using Tmax data in 16 wells from different tectonic subdivisions were carried out. The major problems for using Tmax data were found to be contamination by drilling-mud additives, natural bitumen and suppression due to hydrogen index (HI) > 150 in some wells. Although the data reveal uncertainties and there is about ±3-10 % error for thermal modelling by using the proposed relationship of Ro and Tmax, the "reliable" Tmax data are found to be important, and useful to assess thermal maturity and reduce the influence of unexpectedly low Ro data.This study analyzed the characteristics of deep overpressured zones and top pressure seals, in detail, in 7 wells based on the observed fluid pressure data and petrophysical data. The deep overpressured system (depth greater than 2650-3000 m) in the Jurassic formations and the lower part of the Barrow Group is shown by the measured fluid pressure data including RFTs, DSTs and mud weights. The highly overpressured Jurassic fine-grained rocks also exhibit well-log responses of high sonic transit times and low formation resistivities. The deep overpressured zone, however, may not necessarily be caused by anomalously high porosities due to undercompaction. The porosities in the deep overpressured Jurassic rocks may be significantly less than the well-log derived porosities, which may indicate that the sonic-log and resistivity-log also directly respond to the overpressuring in the deep overpressured fine-grained rocks of the sub-basins. Based on the profiles of fluid pressure and well-log data in 5 wells of the Barrow Sub-basin, a top pressure seal was interpreted to be consistent with the transitional pressure zone in the Barrow Sub-basin. This top pressure seal was observed to consist of a rock layer of 60-80 % claystone and siltstone. The depths of the rock layer range from 2650 m to 3300 m with thicknesses of 300-500 m and temperatures of 110-135 °C. Based on the well-log data, measured porosity and sandstone diagenesis, the rock layer seems to be well compacted and cemented with a porosity range of about 2-5 % and calculated permeabilities of about 10-19 to 10-22 M2.This study performed thermal history and maturity modelling in 14 wells using the BasinMod 1D software. It was found that the thermal maturity data in 4 wells are consistent with the maturity curves predicted by the rifting heat flow history associated with the tectonic regime of this basin. The maximum heat flows during the rift event of the Jurassic and earliest Cretaceous possibly ranged from 60-70 mW/m2 along the sub-basins and 70-80 mW/m2 on the southern and central Exmouth Plateau. This study also carried out two case studies of thermal maturity and thermal modelling within the deep overpressured system in the Barrow and Bambra wells of the Barrow Sub-basin. These case studies were aimed at understanding whether overpressure has a determinable influence on thermal maturation in this region. It was found that there is no evidence for overpressure-related retardation of thermal maturity in the deep overpressured system, based on the measured maturity, biomarker maturity parameters and 1D thermal modelling. Therefore, based on the data analysed, overpressure is an insignificant factor in thermal maturity and h hydrocarbon generation in this basin.Three seismic lines in the Exmouth, Barrow and Dampier Sub-basins were selected and converted to depth cross-sections, and then 2D geological models were created for overpressure evolution modelling. A major object of these 2D geological models was to define the critical faults. A top pressure seal was also detected based on the 2D model of the Barrow Sub-basin. Two-dimensional overpressure modelling was performed using the BasinMod 2D software. The mathematical 2D model takes into consideration compaction, fluid thermal expansion, pressure produced by hydrocarbon generation and quartz cementation. The sealed overpressured conditions can be modelled with fault sealing, bottom pressure seal (permeabilities of 10-23 to 10-25 M2 ) and top pressure seal (permeabilities of 10-19 to 10-22 m2). The modelling supports the development of a top pressure seal with quartz cementation. The 2D modelling suggests the rapid sedimentation rates can cause compaction disequilibrium in the fine-grained rocks, which may be a mechanism for overpressure generation during the Jurassic to the Early Cretaceous. The data suggest that the present-day deep overpressure is not associated with the porosity anomaly due to compaction disequilibrium and that compaction may be much less important than recurrent pressure charges because most of the porosity in the Jurassic source rocks has been lost through compaction and deposition rates have been very slow since the beginning of the Cainozoic.Three simple 1D models were developed and applied to estimate how rapidly the overpressure dissipates. The results suggest that the present day overpressure would be almost dissipated after 2 million years with a pressure seal with an average permeability of 10-22 M2 (10-7 md). On the basis of numerous accumulations of oil and gas to be expelled from the overpressured Jurassic source rocks in the basin and the pressure seal modelling, it seems that the top pressure seal with permeabilities of 10-19 to 10-22 M2 (10-4 to 10-7 md) is not enough to retain the deep overpressure for tens of millions of years without pressure recharging. Only if the permeabilities were 10-23 m2 (10-8 md) or less, would a long-lived overpressured system be preserved. This study suggests that hydrocarbon generation, especially gas generation and thermal expansion, within sealed conditions of low-permeability is a likely major cause for maintaining the deep overpressure over the past tens of millions of years.

The depths of the rock layer range from 2650 m to 3300 m with thicknesses of 300-500 m and temperatures of 110-135 °C. Based on the well-log data, measured porosity and sandstone diagenesis, the rock layer seems to be well compacted and cemented with a porosity range of about 2-5 % and calculated permeabilities of about 10-19 to 10-22 M2.
This study performed thermal history and maturity modelling in 14 wells using the BasinMod 1D software. It was found that the thermal maturity data in 4 wells are consistent with the maturity curves predicted by the rifting heat flow history associated with the tectonic regime of this basin. The maximum heat flows during the rift event of the Jurassic and earliest Cretaceous possibly ranged from 60-70 mW/m2 along the sub-basins and 70-80 mW/m2 on the southern and central Exmouth Plateau. This study also carried out two case studies of thermal maturity and thermal modelling within the deep overpressured system in the Barrow and Bambra wells of the Barrow Sub-basin. These case studies were aimed at understanding whether overpressure has a determinable influence on thermal maturation in this region. It was found that there is no evidence for overpressure-related retardation of thermal maturity in the deep overpressured system, based on the measured maturity, biomarker maturity parameters and 1D thermal modelling. Therefore, based on the data analysed, overpressure is an insignificant factor in thermal maturity and h hydrocarbon generation in this basin.
Three seismic lines in the Exmouth, Barrow and Dampier Sub-basins were selected and converted to depth cross-sections, and then 2D geological models were created for overpressure evolution modelling. A major object of these 2D geological models was to define the critical faults. A top pressure seal was also detected based on the 2D model of the Barrow Sub-basin. Two-dimensional overpressure modelling was performed using the BasinMod 2D software. The mathematical 2D model takes into consideration compaction, fluid thermal expansion, pressure produced by hydrocarbon generation and quartz cementation. The sealed overpressured conditions can be modelled with fault sealing, bottom pressure seal (permeabilities of 10-23 to 10-25 M2 ) and top pressure seal (permeabilities of 10-19 to 10-22 m2). The modelling supports the development of a top pressure seal with quartz cementation. The 2D modelling suggests the rapid sedimentation rates can cause compaction disequilibrium in the fine-grained rocks, which may be a mechanism for overpressure generation during the Jurassic to the Early Cretaceous. The data suggest that the present-day deep overpressure is not associated with the porosity anomaly due to compaction disequilibrium and that compaction may be much less important than recurrent pressure charges because most of the porosity in the Jurassic source rocks has been lost through compaction and deposition rates have been very slow since the beginning of the Cainozoic.
Three simple 1D models were developed and applied to estimate how rapidly the overpressure dissipates. The results suggest that the present day overpressure would be almost dissipated after 2 million years with a pressure seal with an average permeability of 10-22 M2 (10-7 md). On the basis of numerous accumulations of oil and gas to be expelled from the overpressured Jurassic source rocks in the basin and the pressure seal modelling, it seems that the top pressure seal with permeabilities of 10-19 to 10-22 M2 (10-4 to 10-7 md) is not enough to retain the deep overpressure for tens of millions of years without pressure recharging. Only if the permeabilities were 10-23 m2 (10-8 md) or less, would a long-lived overpressured system be preserved. This study suggests that hydrocarbon generation, especially gas generation and thermal expansion, within sealed conditions of low-permeability is a likely major cause for maintaining the deep overpressure over the past tens of millions of years.

Full textAbstract:
This research investigates generational differences in Australian workers. In particular it focuses on changing trends and influences in the workplace and how different generations view and deal with these changes. The study focuses on Baby Boomers (born 1945-1963), Generation X (born 1964-1977) and Generation Y (born 1978 - 1994) across four industry sectors: Corporate, Education, Government and Not for Profit. The Australian workforce currently consists of four generations - all having distinct characteristics, working styles, needs and expectations. These differences pose challenges and opportunities to workforce management. The first step in managing the generations and their differences is to identify where the differences lie and to understand how best to cope with and exploit these differences. This research, in taking a generational cohort perspective towards analysing the modern workplace, seeks to explore how the different generations view the trends and influences that impact their work; and their attitudes towards technology, communication, work/life balance, organisational loyalty, attraction, engagement and retention. The study uses a multi-phase qualitative approach and includes in-depth interviews with a range of Australian industry experts; discussion groups held with Gen Ys, Gen Xers and Baby Boomer employees, in four organisations across four industry sectors; and in-depth interviews with senior executives in the same four organisations. This research will have significance to all organisations especially those that employ workers from across the generations and who are managing a multigenerational workforce. The findings will have practical application to organisational policy development in areas such as, work/life balance, attraction, engagement and retention of employees, reward and recognition systems, technology in the workplace and training and development. The study adds to the body of knowledge in workforce management, and in particular to the emerging body of knowledge on generational cohort analysis of the workplace in the Australian context. The study found significant generational differences that when harnessed and managed effectively, can contribute to the output and performance of the organisation as a whole.

Full textAbstract:
The challenges associated with environmental monitoring such as the impact on the environment and the financial costs are problems we face when trying to conserve freshwater systems around the world. The need for precise and accurate results that are cost effective is important so that we can achieve our conservation goals.
The overall aim of this study was to explore Next-Generation - metabarcoding for the detection of feral and native freshwater fish species based on the DNA shed by individual organisms into the water column. Cytochrome c oxidase I (COI) primers were developed for this study using DNA from six freshwater species expected to be found in the waterbody. These primers, along with 16S rRNA (16S) primers, were assessed to ensure that the molecular method was robust and suitable for use in the field. Along with the cost effectiveness of the molecular method when compared to the more traditional surveying method of Fyke net surveying.
This study comprised development of field and lab protocols for the detection of freshwater fish species in a lentic system. Both the COI and 16S primer sets showed results that were comparable to previous Fyke net surveys, though both primer sets detected species that the other did not. Further qPCR analysis showed that there were differences in detection for both primers for each of the species. The molecular surveying of the waterbody has been proven sensitive enough to detect Maccullochella peelii. This species has a very low abundance in the waterbody (believed to be n=1) so these results suggest that this method can be used to target low abundance species.
The outcome of this study highlighted the need for multi-location sampling within a waterbody as increasing the number of locations sampled, led to an increase in the number of species detected. Along with the multi-location sampling, it was also important to sample throughout the year to account for seasonal variability. The eDNA study emphasized the importance of having knowledge of both the ecology and the biology of the species targeted so that a robust monitoring method can be implemented.
As well as comparing the apparent accuracy of Fyke netting and the eDNA approach in the study waterbody, a cost benefit analysis comparing the relative costs of multiplex DNA surveying, single species molecular surveying, and Fyke net surveying was undertaken. Molecular environmental surveying was found to be a cost effective method for monitoring, as the analysis suggested single species monitoring would break even after only 95 waterbodies were surveyed, and multiplex surveying would break even after 145 waterbodies, under the proposed scenario. The cost benefit analysis explored the costs associated with all three methods, including lab set up costs, along with the number of waterbodies that could be surveyed on both a weekly and yearly basis.

Full textAbstract:
The International Organization for Migration’s World Migration Report (2020) estimates the number of migrants worldwide to be approximately 272 million. In an era of demographic scarcity and globalisation-driven uncertainties, asylum seeker, migration, and refugee re-settlement programs are now a worldwide phenomenon. Major English-speaking, immigrant-receiving countries such as Australia, Canada, New Zealand, the United Kingdom, and the United States of America (USA) face associated educational, political, and social repercussions.
Rumbaut and Ima (1988) introduced the term ‘Generation 1.5’ in relation to a distinct cohort of immigrant youth, English as second language (L2) learners studying in San Diego, California in the USA. This term signifies learners neither part of the first generation in an immigrant-receiving country, nor part of the second generation of children born in that country. North American-based research finds these learners are generally not fully proficient in either their first language or their L2. While typically possessing well-developed basic interpersonal communicative skills, learners are less skilled in terms of the cognitive academic learning proficiency levels that are essential for academic achievement. Additionally, they may lack discrete language skills, the rule-governed areas that include grammar, phonology, and spelling. However, the crucial academic L2 variables relate to immigrants’ age-on-arrival and length of residence in their host countries.
In Australian tertiary education, the implications of having increasing numbers of university students meeting this learner profile remains under-researched. This study investigated how six participants meeting the Generation 1.5 learner profile managed their undergraduate studies in a Perth-based, public university in Western Australia over an academic year. This arts-informed study used an interpretivist paradigm, with symbolic interactionism as the theoretical position, and grounded theory (GT) methodology (Strauss & Corbin, 1990). Semi-structured, in-depth interviews and written responses to research questions comprised the major data-generation methods. Data analysis used GT open, axial, and selective coding in conjunction with memo-writing and Resource Journal commentaries. The iterative process of data analysis and literature access that included arts-informed, non-technical, and technical material collectively informed the study findings.
As the ‘grounded theory’ driver, ‘wanting-it-all-regardless’ dominated the data findings, within which the core category, the Academic Highway Journey, and the five major categories were identified. These major categories comprised academic, coping, identity, immigration, and learning systems. In using an astronomy metaphor, the core category or newly-discovered planetary force has five major categories or satellite systems orbiting within its sphere of influence. These GT-generated components resulted in developing the Wanting-It-All-Regardless Theory (the Theory). This Theory explained how the research participants, in ‘misframing’ their Academic Highway Journeys, managed the barriers, breakdowns, and breakthroughs experienced along the way.
Making an original and important contribution to Australian-based Generation 1.5 learner research, study findings highlighted major pedagogical policy, program, and practice implications. As evidenced in this study, high school is no longer considered the educational ‘finish line’. The participants in this study, either as high school graduates, university preparation courses attendees, or as having limited, formal L2 instruction, were inadequately prepared and supported during their academic journeys. Paradoxically, for these participants, university acceptance and course enrolment were conflated with having the L2 academic resources necessary to succeed educationally. In an increasingly uncertain and unstable globally connected and interconnected world, major immigration-destination countries such as Australia must urgently address the Generation 1.5 learner area as a significant impact of increasing demographic scarcity.

Thesis, Edith Cowan University, Research Online, Perth, Western Australia, 2015. https://ro.ecu.edu.au/theses/1632.
Full textAbstract:
There has been a recent upsurge in media attention surrounding Australia’s ageing workforce. A review of academic, media and grey literature highlighted inadequacies in existing workplace polices, as well as flaws in financial and social security schemes. Of particular concern were persistent negative attitudes and counterproductive policies regarding mature age employees (MAEs). Poor retention rates among this cohort of workers aged 45 years and over are leading to skilled labour shortages and losses in corporate knowledge. This expected mass exodus of mature cohorts into retirement has been predicted to negatively impact the socio-economic sustainability of ageing societies world-wide and is a pertinent issue for Western Australia (WA).
The overarching objective of this study was to identify the ‘place’ of mature cohorts within WA workplaces and promote strategies that will improve the employment conditions and overall quality of life of ageing workforces. Research questions aimed to address the need for greater mature age employment up to and beyond pensionable age; identify ‘gaps’ in policies and programmes; and explore how mature cohorts were perceived (valued) and the extent their departure may affect WA society (labour force).
By using a mixed methods research design, this Doctoral dissertation developed a conceptual framework for limiting significant issues individuals, businesses and society may experience as a result of WA’s ageing workforce; whilst simultaneously promoting the benefits of maturity and mature age employment. This Re-Model draws upon the community development work principles of social justice, empowerment and social capital; and is further contextualised by methods of best practice identified from the triangulation of secondary sources, quantitative data and qualitative inquiry. Primary data collection involved the completion of 362 surveys, followed by 27 semistructured interviews and four focus group activities, with a cross section of MAEs, volunteers, their employers, retirees and unemployed cohorts from across WA.
Over one-third of current MAEs, employers and volunteers in this study reported they intended working later than the traditional age of retirement, with 71 per cent of this sample planning to semi-retire. Furthermore, almost 60 per cent of a sample that had previously exited the labour force was working at the time of data collection as semi-retirees or rehired retirees (rehirees). Collectively, these statistics indicated that despite predictions of mass disengagement among mature cohorts, most of this crosssection of Western Australians are seeking to remain in (or re-enter) the WA workforce beyond pensionable age. However, quantitative and qualitative findings revealed several barriers to their continued engagement, including access to ‘age-friendly’ workplaces; a dearth of targeted training (career) development and employment assistance; and a lack of value attributed to mature age skills and experience, particularly deleterious in WA’s youth-centric culture.
Primary data also highlighted several enabling factors for mature age employment. ‘Flexibility’ and ‘autonomy of choice’ were cited as key dimensions across all aspects of paid work, volunteering and retirement – whether in terms of worklife- balance; the individuation of training and development; or options available to those transitioning out of traditional employment. Data indicated that sustainable cultural change required more than just the removal of negative policies or introduction of punitive legislation. Maintaining a positive outlook among mature age individuals and simultaneously educating (younger) co-workers, employers, policy-makers (stakeholders) and society about the virtues of maturity and non-traditional work (skills) were considered essential to changing societal attitudes, behaviour and culture.

Full textAbstract:
In a carbon constrained world, transitioning some or all of the fuel for transport away from fossil fuels to renewable sources of energy will become increasingly important. This dissertation examines the current penetration of first generation biodiesel in the Australian diesel market and identifies the factors that will most influence current and future penetration.
The research identifies three critical factors in shaping penetration: price relativity to mineral (regular) diesel, government policy, and the environmental benefits of biodiesel. This dissertation concludes that these factors will be definitive in determining the penetration of biodiesel in the Australian diesel market.
Analysis of price relativity shows that mineral diesel is currently cheaper to supply than biodiesel, despite significant subsidisation. Importantly, the research also shows that biodiesel is likely to remain more expensive than mineral diesel under a carbon price or carbon tax regime.
The biodiesel policies and programs at the federal and state government levels are examined and critically assessed. The option of mandated targets is discussed and analysed. The research finds that despite several programs and policies currently in place, there is a lack of overall policy direction on biodiesel in the short term. The analysis also highlights the significant potential for government policy to shape pricing relativity – either in favour of, or against biodiesel.
The environmental and sustainability benefits of first generation biodiesel are assessed. The emerging role of the various sustainability roundtables in providing sustainability assurance is outlined and discussed. The research concludes that biodiesel does offer both environmental and sustainability benefits over mineral diesel – providing that sustainability criteria are adhered to. The research also concludes that there is not a clear consensus on those credentials among the various stakeholders and that more needs to be done to increase awareness of those benefits to foster uptake.

Full textAbstract:
In August 2000, Justice O�Loughlin of the Federal Court of Australia handed down the decision in Cubillo v Commonwealth in which Lorna Cubillo and Peter Gunner took action against the Commonwealth Government, arguing that it was vicariously liable for their removal from their families and communities as children and subsequent detentions in the Northern Territory during the 1940s and 1950s. The case is the landmark decision in relation to legal action taken by members of the Stolen Generations.
Using the decision in Cubillo as a key site of contestation, my thesis provides a critique of legal positivism as the dominant jurisprudential discourse operating within the Anglo-Australian legal system. I argue that the function of legal positivism as the principal paradigm and source of authority for the decision serves to ensure that the debate concerning reconciliation in Australia operates rhetorically to maintain whiteness at the centre of political and discursive power. Specifically concerned with the performative function of legal discourse, the thesis is an interrogation of the interface of law and language, of rhetoric, and the semiotics of legal discourse.
The dominant theory of evidence law is a rationalist and empiricist epistemology in which oral testimony and documentary evidence are regarded as mediating the relationship between proof and truth. I argue that by attributing primacy to principles of rationality, objectivity and narrative coherence, and by privileging that which is visually represented, the decision serves an ideological purpose which diminishes the significance of race in the construction of knowledge.
Legal positivism identifies the knowing subject and the object of knowledge as discrete entities. However, I argue that in Cubillo, Justice O�Loughlin inscribes himself into the text of the judgment and in doing so, reveals the way in which textual and corporeal specificities undermine the pretence of objective judgment and therefore the source of judicial authority.

Full textAbstract:
This dissertation examines the question: what is the maximum level of annual electricity consumption in South Australian (SA) that can be met by renewable energy generation when the SA electrical system is ‘islanded’ from the National Electricity Market (NEM). The term ‘islanded’ refers to the SA electricity network being disconnected from the NEM.
Examination will be through technical desktop analysis of available data, feasibility studies, white papers and reports on the SA electricity network and the NEM. Regulatory, policy and pricing implications will also be examined.
The SA NEM region is identified as having approximately 45% of the NEM’s installed wind energy generation, relatively small demand and therefore at times very high renewable energy penetration and an area with yet still significant untapped renewable resources. It is this criteria that make SA the ideal subject of this dissertation.
A brief overview of the SA NEM is provided, including examination of wholesale spot market pricing, maximum and average generation figures, effects of renewable generation on the operation of the NEM region and on the wholesale spot market, and technical and regulatory issues relating to renewable generation. Renewable generation in SA was found to place downward pressure on wholesale electricity prices and has a level of untapped renewable resources that could generate sufficient electricity to meet a percentage of annual consumption in the state far in exceedance of existing levels.
The Renewable Energy Target (RET) is examined in the context of the South Australian region of the NEM. The RET was found to be responsible for all large scale renewable generation developed in South Australia, noting that residential solar, although substantial in installed capacity, was developed through feed-in tariffs (FiT). The continuation of the RET was found to be of critical importance to the continuing renewable energy generation.
Technical requirements for existing and increased levels of renewable generation is examined. The conclusion was that renewable generation could be increased within existing technical standards. Modern wind and solar photovoltaic (PV) developments have inherent technologies in their power electronics that assist in the maintenance of system stability; strengthening and improving of those technologies may be required for increased levels of renewable generation (ie inertia support).
Future supply adequacy is examined to identify potential opportunities for renewable generation to increase its share of meeting SA’s annual electricity consumption. It was found that there is no new capacity required in the SA NEM region over the next 10 years. This was in part due to the resistance of coal fired power station operators to close down plant that have exceeded their useful operating life. This resistance is in the form of high exit costs, a lack of a price on carbon and in part carbon tax compensation. Repercussions of fossil fuel generation operating beyond design life (and with a low Log Run Marginal Cost (LRMC) due to lack of price on carbon and being at the end of its life and therefore capital costs having been paid off), may be lack of new generation in future years from continuing low wholesale prices and from a perceived surplus of generation. Increased levels of renewable generation was not found to be problematic in terms supply adequacy, if retirement of aging thermal plant is managed.
Localised effects of renewable generation on substations are examined, with the realisation that smart grid technologies will be to be vital to the enabling of further intermittent generation and that benefits such as peak shaving were not being realised. Smart grid technologies would provide Distribution Network Service Providers (DNSP) and Transmission Network Service Providers (TNSP) the capability to determine near real time status of parameters such as voltage level rise, assisting in maintaining the security of the network and ensuring operational activities, such as excessive transformer tap changing, does not reduce equipment life. The often stated potential benefits of renewable generation of peak shaving and delayed infrastructure investment were examined and found to be of little benefit. Alternate methods of enhancing renewable generation would be required to ensure often these benefits are realised, western orientated solar arrays is one proposed solution to realising peak shaving benefits.
Current market distortions are discussed such as market failure to place a price on environmental and health effects of fossil fuel generation (ie price on carbon). A case is also make a case for intervention in the market to achieve optimum social and environmental outcomes.
In summary, there exists the renewable resources and technical capability for significant additional renewable generation in the SA NEM. The extensive analysis and modelling in this area, by Australian Energy Market Operator (AEMO) in particular, has provided the assurance that a significant increase in renewable generation is achievable within the existing NEM operational and technical constraints. South Australia is also well placed with planning laws favourable to renewable generation.

The centrality of the thesis is the impact upon the individual Greek migrant who chose to leave his place of birth by emigrating, repatriating, and subsequently re-emigrating, and how the surreptitious nature of acculturation alters perceptions and thoughts. The causes of such migratory translocations will be analyzed within the sociocultural and historicoeconomic conditions that appertained at the time the decisions were taken to deracinate oneself. The study will provide an analysis of diachronic Hellenic migration and Australian immigration policies (since its inception as a federated state). There will also be an analysis of Australia�s diachronic and dedicated immigration control mechanisms since federation, its various post-immigration integration policies of immigrants, the mass immigration program activated in the post-WWII period, and the adoption and incorporation of multiculturalism as the guiding force in migrant selection and integration. Australia�s history, its cultural inheritance, its socioeconomic development, and its attraction as a receiving country of immigrants are analyzed, as are Australia�s xenophobia and racism at its inception, and how these twin social factors influenced its immigration program. The study examines limitations placed upon social intercourse, employment opportunities, and other hindrances to Greek (and other non-British migrants) immigrants because of Australia�s adoption of restrictive, racially-based immigration policies. The study focuses upon the under-development of Hellas in the first half of the twentieth century, its high unemployment and under-employment rates, and the multiple other reasons, aside form unemployment, which forced thousands of Hellenes to seek an alternative (for a better life) through internal or external migration. Particular emphasis will be placed upon historic occasions in Greece�s history and the influence of foreign powers upon internal Greek politics. The motivations for each distinct stage of translocation, in the lives of the respondents, will be examined within the ambit of social, cultural, economic, and historical context, which will place emphasis on the socioeconomic development of Hellas, the development of Hellenic Diaspora, Australia�s development as a receiving immigrant country, and the effects of acculturation and nostalgia upon first-generation Greek-Australians. Given that the thesis is based upon personal recollections and detailed information that span decades of the respondents� lives, the thesis is divided into four parts for greater clarity and comprehension: the first examines respondents� lives in region of birth, their families� economic, educational, and social environment, scholastic achievements by respondents, employment status, future prospects, religiosity, hopes and aspirations, and reasons for seeking to migrate. The second part examines respondents� lives in Australia, within the contextuality of accommodation, employment, family creation, social adaptation, language acquisition, attitude towards unionism and religion, expectations about Australia, and reasons for repatriating. The third part analyzes repatriation and life in Greece through resettlement, accommodation, children�s schooling and adaptation, relatives� and friends� attitude, disappointments, and longing for things Australian, while it also examines re-emigratory causes and the disillusionment suffered through repatriation. The final part assesses resettlement in Australia, and all associated social, economic, and environmental aspects, as well as respondents� children�s readaptation to different lifestyle and educational system. The thesis concludes with recommendations for possible further studies associated with the thesis� nature.

Full textAbstract:
In Queensland, there is little research that speaks to the historical experiences of schooling. Aboriginal education remains a part of the silenced history of Aboriginal people. This thesis presents stories of schooling from Aboriginal people across three generations of adult storytellers. Elders, grandparents, and young parents involved in an early childhood urban playgroup were included. Stories from the children attending the playgroup were also welcomed.
The research methodology involved narrative storywork. This is culturally appropriate because Aboriginal stories connect the past with the present. The conceptual framework for the research draws on decolonising theory. Typically, reports of Aboriginal schooling and outcomes position Aboriginal families and children within a deficit discourse.
The issues and challenges faced by urban Murri families who have young children or children in school are largely unknown.
This research allowed Aboriginal families to participate in an engaged dialogue about their childhood and offered opportunities to tell their stories of education. Key research questions were: What was the reality of school for different generations of Indigenous people? What beliefs and values are held about mainstream education for Indigenous children? What ideas are communicated about school across generations? Narratives from five elders, five grandparents, and five (urban) mothers of young Indigenous children are presented. The elders offer testimony on their recollected experiences of schooling in a mission, a Yumba school (fringe-dwellers’ camp), and country schools. Their stories also speak to the need to pass as non-indigenous and act as “white”. The next generation of storytellers are the grandparents and they speak to their lives as “stolen children”. The final story tellers are the Murri parents.

Full textAbstract:
The research reported in this thesis explored the Fethullah Gülen’s educational vision and its interpretation in two Australian Gülen–inspired schools. The educational and social services he started with his close friends in the late 1960s grew rapidly and has become known as the Hizmet Movement. Although the Movement is involved in many different activities, intercultural dialogue and educational services are its main pursuits. Gülen’s educational vision and inspiration have resulted in the establishment of educational institutions, such as childcare, schools, tutoring centres, and universities, all around the world. The research in this thesis focussed on identifying the specific educational characteristics of two Australian schools founded on Gülen’s philosophy. The researcher examined a range of primary and secondary literature sources to analyse Fethullah Gülen’s educational vision to provide a background. Gülen’s educational vision emphasises integrity of the heart and intellect––academic and values education, and aims to raise virtuous individuals through holistic education, transforming knowledge into character development and role modelling. His educational vision reconciles science and religion, and approaches education as the best way to serve humanity. To explore the specific educational characteristics in schools, a case study approach was adopted with data being obtained from interviews, participant observation and school documents to identify the characteristics of the two schools in different Australian cities founded on Gülen’s philosophy and to determine how Gülen’s inspiration was transformed into practices at the schools. The major findings were that the schools were values–based and academically oriented. They adopted a balanced education that encompassed academic excellence and delivered values education to raise what Gülen terms the Golden Generation, an ideal generation that is well–educated in the sciences, and who possess deep ethical and moral grounding. The schools emphasised pastoral care services to further support students’ academic, moral and social development. Both schools were established and supported by the community, and addressed community values in the school environment. This thesis is significant as it is the first study that examines two Australian Gülen–inspired schools and their alignment with Gülen’s philosophy. It concludes with the potential contribution of Gülen’s educational philosophy and Gülen–inspired schools to the wider educational field, recommendations to two schools from findings and suggestions for further studies.

Full textAbstract:
This thesis focuses on processes of Aboriginal community-making in Redfern, an inner city suburb of Sydney, Australia. It addresses the ways in which the Australian state governs Aboriginal people by developing 'projects of legibility' (and illegibility) concerning Aboriginal community sociality. To address Redfern Aboriginal community-making requires focusing on the ambiguities arising from the contemporary policy of 'Aboriginal self-determination' and adopting an ethnohistorical approach to Aboriginal community-making that has arisen under this policy rubric. By ethnohistorical I refer to the engagement of Aboriginal people in Redfern in Aboriginal community-making policy practices and not a historiography of these policies. Attention will be paid to past and present negotiations concerning the (re)development of the Redfern Aboriginal community and their intersections in the state-led redevelopment process Aboriginal community- makers were engaged in during the course of my research in 2005-2007. These negotiations centre on attempts made to reproduce certain forms of sociality that both reveal and obscure Aboriginal social relations when inscribed in the category 'Aboriginal community'. This analysis is meant to contribute to the limited anthropological research that exists on urban Aboriginal experiences generally and research conducted on Aboriginal experiences in southeastern Australia. It addresses the complex social field of Aboriginal community-making practices that exist in Australia where Aboriginal and non-Aboriginal Australians are located within the bureaucratic structures of the state, institutional networks, as well as non-government community organisations. This research contributes to understanding 'the institutional construction of indigeneity' (Weiner 2006: 19) and how this informs the (re)development of urban Aboriginal communities.

Full textAbstract:
The study systematically analyses the location of second-generation Australian
adults (defined as those born in Australia of an immigrant father) in the economic
system, it investigates their educational achievements, and examines the nature of
influences on their political behaviour by specifying relations among certain variables
and by comparing them to first-generation immigrants and to the native-born of a
native-born father. The one per cent person's sample file of the 1981 Australian census
on population and housing is used for analyses of income and education; the 1984/1985
National Social Science Survey (urban preliminary sample) is used to investigate
partisanship, participation and felt efficacy. The study draws mostly on American
literature for its theoretical underpinnings.
The conceptual basis of this study involves a three-fold distinction: the
socioeconomic system, the cultural, or 'ethnic', dimension and the political system. The
socioeconomic system is explored largely in the economic domain in terms of individual
income and educational achievement, the ethnic or cultural dimension in terms of the
extent of economic and educational integration and in terms of influences on political
behaviour. Ethnicity is defined mainly in terms of father's birthplace. The political
system is examined through extent and strength of, and influences on, partisanship,
through political participation and through felt political efficacy.
The model which best describes the political life of second-generation Australians
in the early 1980s is partial assimilation. Their pattern of political adaptation is
piecemeal, complex and at times puzzling. Political adaptation appears to be a function
both of location in some important sociocultural systems and of cultural differentiation.
Ethnicity permeates political adaptation, although its effects vary across the major
subsystems of society. In short, a dual explanation - economic and cultural - is
required.
Many features parallel the adaptation of the second generation in the United States
half a century ago, perhaps the most general being that adaptation and ethnicity are
interwoven in concept and reality. But unlike what appears to be the American
experience, most second-generation Australians have been assimilated into the economic
system by virtue of their success in gaining incomes which are at least the equivalent of
those earned by other native-born Australians.

Full textAbstract:
Generation Y, the colloquial term applied to those born from 1980-1998, will become the dominant cohort in the Australian workforce in the current decade, outnumbering both preceding generation cohorts - the Baby Boomers (born 1945-1962) and Generation X (born 1963-1979). Accounts across extant literature suggest Generation Y work values represent a distinct challenge to existing workplace norms and attitudes.
The Australian Public Service (APS), employing over 160,000 people, has identified the recruitment and retention of Generation Y (representing almost one-third of its workforce) as a strategic concern (APSC, 2005). Using the qualitative approaches of scenario modelling, narrative-based semi-structured interviews and open-ended self-report questionnaires, this study examines the work values of Generation Y participants using a student sample (N = 161) and a sample of current APS employees (N = 60). Generation Y work values data are contrasted with the perceptions of APS managers (N = 20) and examined within the theoretical context of the employment relationship, viewed through the lens of the psychological contract and the theory of person-organisation fit. Data analysis is based on Charmaz's (2006) systematic, grounded theory-based approach.
Data suggest that the APS setting represents a good degree of fit with Generation Y work values preferences for inclusive management and workplace processes; the ability to make a social contribution; organisational ethics; long-term careers and ongoing development; adequate work-life balance; and, interactive communication. Findings suggest a partial fit with the values preference for pragmatism. Misfit between the APS values and Generation Y work values is evident where the APS structure is based on hierarchical processes and Generation Y work values favour immediacy in workplace decisions. Overall findings suggest a positive Generation Y-APS employment relationship. The theoretical and practical implications of these findings are discussed with reference to existing literature.

Full textAbstract:
Temporary migration has seen tremendous growth in recent years, and a variety of forms and trends have emerged. The Working Holiday (WH) is a new and novel form of temporary, international youth migration, increasingly popular among people from developed countries. The Australian WH scheme invites young people to temporarily live, study, work and holiday in the country for up to two years. It has steadily grown to accommodate tens of thousands of youths every year. Since the reciprocal agreement was established in 1980, Japan has become one of the major source countries of Working Holiday Makers (WHMs) in Australia, which in turn has consistently maintained its status as the top destination for the young Japanese. This thesis understands the mobility of Japanese WHMs to be a form of youth sojourn, and explores the role it plays in young people's self-making. My focus is on the particular period called the 'lost decade' (ushinawareta junen), involving the gradual collapse of the 'bubble' economy since the market crash of late 1989, from which the country has never fully recovered. The Japanese WHMs in this study belong to what has been termed the 'lost generation' (rosuto jenereshon, or rosujene), those whose life trajectories have been heavily influenced by the massive socio-economic changes associated with this era. My discussion draws on fieldwork conducted in Japan and Australia, where I engaged in participant observation and gathered interview narratives from people at various stages of their mobility, including prior to departure, sojourn in Australia, and return migration. My analysis ventures into several under-researched, yet fascinating areas: The WH as an exemplar of contemporary international mobility, which challenges the dichotomy between work-as-toil and leisure-as-pleasure; youth temporary migrants from a post-industrial society as occupying classed , gendered and ethnicised subject positions; intersection of economic and non-economic factors in migratory decision-making and experience; and the treatment of different phases of migration as a cumulative whole, as well as part of a wider life trajectory. In particular, I bring to the fore the issue of labour in an unlikely context of youth mobility between develop ed economies . Through a micro-level study of motivations, desires and agency, this thesis highlights the ways in which certain discourses and socio-economic practices are shaped by global forces, and how individual WHMs reproduce, conform to and resist such forces. My case study is a portrayal of how young people proactively and continuously seek to explore and develop their selves, as they search for an elusive sense of fulfilment in the late modern neoliberal world.

Full textAbstract:
This item is only available electronically.Over 261 naturally occurring fractures were recorded from 10 field locations in the Otway Ranges, Victoria, Australia. Fractures were sampled from the upper Jurassic –lower Cretaceous Eumeralla Formation, a volcanogenic sandstone. Eight fracture sets were recorded with defined orientations. Twenty-seven fracture samples from across the Otway Ranges were thin sectioned and analysed using an optical microscope and Scanning Electron Microscope (SEM). Host rock and fracture petrography were determined, including identification of host rock and fracture cement mineral compositions, along with fracture specific textures, such as calcite twinning, crack-seal textures, cataclastic deformation and cross-cutting cements. Siderite cements are observed to be present in all fracture sets and imply the presence of fluid flow during all periods of deformation, from lower Cretaceous extension to NW –SE Miocene compression. The addition of calcite cements in Fracture Sets One, Fracture Set Two, Fracture Set Four, Fracture Set Five and Fracture Set Seven indicate two periods of enhanced calcite and siderite fluid flow predominantly during times of NW - SE compression in the mid-Cretaceous and Miocene.

Full textAbstract:
The average length of life from birth until death in a human population is a single statistic that is often used to characterise the prevailing health status of the population. It is one of many statistics calculated from an analysis that, for each age, combines the number of deaths with the size of the population in which these deaths occur. This analysis is generally known as life table analysis. Life tables have only occasionally been produced specifically for South Australia, although the necessary data has been routinely collected since 1842. In this thesis, the mortality pattern of South Australia over the period of 150 years of European settlement is quantified by using life table analyses and estimates of average length of life. In Chapter 1, a mathematical derivation is given for the lifetime statistical distribution function that is the basis of life table analysis, and from which the average length of life or current expected life is calculated. This derivation uses mathematical notation that clearly shows the deficiency of current expected life as a measure of the life expectancy of an existing population. Four statistical estimation procedures are defined, and the computationally intensive method of bootstrapping is discussed as an estimation procedure for the standard error of each of the estimates of expected life. A generalisation of this method is given to examine the robustness of the estimate of current expected life. In Chapter 2, gender and age-specific mortality and population data are presented for twenty five three-year periods; each period encompassing one of the colonial (1841-1901) or post-Federation (1911-96) censuses that have been taken in South Australia. For both genders within a census period, four types of estimate of current expected life, each with a bootstrap standard error, are calculated and compared, and a robustness assessment is made. In Chapter 3, an alternate measure of life expectancy known as generation expected life is considered. Generation expected life is derived by extracting, from official records arranged in temporal order, the mortality pattern of a notional group of individuals who were born in the same calendar year. Several estimates of generation expected life are calculated using South Australian data, and each estimate is compared to the corresponding estimate of current expected life. Additional estimates of generation expected life calculated using data obtained from the Roll of Honour at the Australian War Memorial quantify the reduction in male generation expected life for 1881-1900 as a consequence of military service during World War I, 1914-18, and the Influenza Pandemic, 1919.Thesis (M.Sc.) -- University of Adelaide, School of Applied Mathematics, 2003.

Full textAbstract:
This thesis describes the communication activities and views of Australia's scientists around their communication with the general public. This exploratory research is based upon a national Internet survey of 1,521 Australian scientists who worked across public and private sectors for eight different types of employers and in seven science disciplines. The scientists were aged between 21 and 67+ years and the survey population was representative of the sex-age distribution of scientists in Australia in 2006.
This study sought to find out if scientists in Australia agreed that they had a responsibility to communicate with the general public, how personally important it was to them, and if there were any benefits for them from doing so. A significant finding of this research is that a large number of scientists have positive feelings about themselves, their communication and their work, as a benefit of communicating with the general public.
Whether communicating with the general public was a part of their job, or otherwise recognised or rewarded, and what scientists did to communicate with the general public is also explored. Hindrances to their communication and areas for improvement are identified. The influence of scientists' sex, age, discipline and employer upon their communication activities and views is analysed. Recommendations for improvement of communication practice are made.Professor Susan Stocklmayer
