Strangers in a strange land : Converging and accommodating Celtic identities in Ballarat 1851-1901
- Authors: Croggon, Janice
- Date: 2002
- Type: Text , Thesis , PhD
- Full Text:
- Description: "This thesis examines the paths by which four Celtic ethnic identities, Cornish, Welsh, Scottish and Irish, responded to the specific society and culture of the Victorian goldfields between 1850-1901. The individual Celtic groups intersected, harmonised and contested with each other in a process through which they retained their identities and yet managed to move towards becoming part of a larger, more-encompassing unity."

The intellectual life of Catherine Helen Spence
- Authors: McFarland, Michele
- Date: 2004
- Type: Text , Thesis , PhD
- Full Text:
- Description: This thesis will argue that Catherine Helen Spence, a writer, preacher and reformer who migrated from Scotland to Australia in 1839, performed the role of a public intellectual in Australia similar to that played by a number of women of letters in Victorian England. While her ideas were strongly influenced by important British and European nineteenth-century intellectual figures and movements, as well as by Enlightenment thought, her work also reflects the different socio-political, historical and cultural environment of Australia. These connections and influences can be seen in her engagement with what were some of the "big ideas" of the nineteenth century, including feminism, socialism, religious scepticism, utopianism and the value of progress. In arguing that Spence was a public intellectual, I will consider the ways in which she used the literary genres of fiction and journalism, as well as her sermons, to try to help her fellow citizens make sense of the world, attempting to organise and articulate some of the significant ideas affecting the political, social and cultural climates in which they lived. Through the exploration of Spence's intellectual work, I will show how she can be regarded as making a significant contribution to nineteenth-century Australian intellectual life, one that has been under-recognised and under-valued.

Progress in Australia over the 20th century : the ups, downs and reversals that occurred in Australian human wellbeing over the 20th century
- Authors: Gathercole, Michael
- Date: 2005
- Type: Text , Thesis , PhD
- Full Text:
- Description: "This study is an investigation of progress in Australia over the 20th century. Progress is defined here as the enhancement of human wellbeing. For the purposes of this study, human wellbeing will be characterised by five main components: knowledge, environment, economy, individual and social. Enhancement refers to positive directional change in terms of these components. The study firstly develops a framework to conceptualise progress. It then collects and uses statistical data in a descriptive study of what happened in Australia, over those 100 years, in terms of progress in general and in terms of its components. The study also develops a typology of relationships for models of progress, which best explain the Australian data. This study finally explores some of the relationships between the elements that make up the components of progress and looks at ways to best explain what has happened..." --p.1.

Effects of commuting status upon community involvement of professionals in rural North West Victoria
- Authors: Devers, Deanna
- Date: 2006
- Type: Text , Thesis , PhD
- Full Text:
- Description: Because mobility is associated with rural social decline, this two-phase cross sectional study investigates whether social patterns in small, rural Australian towns are affected by commuting. Quantitative data, which was gathered via a mail-out questionnaire (response = 54 per cent) that was issued to 1,040 occupationally diverse professionals who worked in fourteen towns throughout north-western Victoria, was analysed to determine whether commuting and non-commuting professionals differed significantly in their community involvement. To explain why certain relationships emerged from survey analysis, face-toface interviews were subsequently undertaken with 24 questionnaire respondents. The key finding of this study is that there is a significant relationship between commuting status and the retention of rural professionals. A significantly greater proportion of noncommuters than commuters remain working in the one location for longer than five years. This finding has important implications for the sustainability of rural areas.

Exploring risk-awareness as a cultural approach to safety : An ethnographic study of a contract maintenance environment
- Authors: Borys, David
- Date: 2007
- Type: Text , Thesis , PhD
- Full Text:
- Description: Safety culture has risen to prominence over the past two decades as a means by which organisations may enhance their safety performance. Safety culture may be conceptualised as an interpretive device that mediates between organisational safety rhetoric and safety programs on the one hand, and local workplace cultures on the other. More recently, risk-awareness has emerged as a cultural approach to safety. Front line workers are encouraged to become risk-aware through programs designed to prompt them to undertake mental or informal risk assessments before commencing work. The problem is that risk-awareness programs have not been the subject of systematic research and the impact of these programs on the culture of safety and the resultant level of risk is unknown. Therefore, this ethnographic study of two sites within a large contract maintenance organisation in Australia explored what impact risk-awareness programs have upon the culture of safety and the resultant level of risk. The researcher spent two months in the field and data was collected through participant observation, semistructured interviews and through a review of organisational documents. This study found that managers focused upon collecting the paperwork associated with the program as proof that workers had a safer workplace, whereas workers preferred to rely upon their common sense rather than the paperwork to keep them safe. As a consequence, the riskawareness program resulted in a culture of paperwork and varying levels of risk reduction because the paperwork associated with the program created an illusion of safety for managers as much as common sense did for workers. The results of this study have implications for safety culture, risk-awareness programs and for organisational learning. They also have implications for organisations wishing to improve their safety culture by encouraging risk-awareness in front-line workers.

Stock market predictions based on quantified intermarket influences
- Authors: Tilakaratne, Chandima
- Date: 2007
- Type: Text , Thesis , PhD
- Full Text:
- Description: This research investigated the feasibility and capability of neural network-based approaches for predicting the direction of the Australian Stock market index (the target market). It includes several aspects: univariate feature selection from the historical time series of the target market, inter-market analysis for finding the most relevant influential markets, investigations of the effect of time cycles on the target market and the discovery of the optimal neural network architectures. Previous research on US stock markets and other international markets have shown that the neural network approach is one of most powerful techniques for predicting stock market behaviour. Neural networks are capable of capturing the non-linear stochastic and chaotic patterns in the stock market time series data. This study discovered that the relative return series of the Open, High, Low and Close prices of the target market, show 6-day cycles during the studied period of about 14 years. Multi-layer feedforward neural networks trained with a backpropagation algorithm were used for the experiments. Two major testing methods: testing with randomly selected test data and forward testing, were examined and compared. The best neural network developed in this study has achieved 87%, 81% 83% and 81% accuracy respectively in predicting the next-day direction of the relative return of the Open, High, Low and Close prices of the target market. The architecture of this network consists of 33 input features, one hidden layer with 3 neurons and 4 output neurons. The best input features set includes the relative returns from 1 to 6 days in the past of the Open, High, Low and Close prices of the target market, the day of the week, and the previous day’s relative return of the Close prices of the US S&P 500 Index, US Dow Jones Industrial Average Index, US Gold/Silver Index, and the US Oil Index.

Work/life balance through a critical ‘gender lens’ : A cross-country comparison of parental leave provisions and take-up in Australia and Sweden
- Authors: Zacharias, Nadine
- Date: 2007
- Type: Text , Thesis , PhD
- Full Text:
- Description: Work/life balance researchers have documented the low take-up rates of corporate work/life balance policies at the same time as there are reports of persistent work/life pressures. This research aims to provide more comprehensive explanations of the phenomenon of low policy take-up than those currently available in the work/life balance literature which focus on organisational and individual factors. The research project is based on a critical review of the work/life balance literature which focuses on organisational solutions and starts from the assumption that the organisational approach to researching and addressing work/life conflicts is inherently limited, mainly because it does not theorise gender as a social structure and does not take into consideration the social and political context in which work/life arrangements are negotiated but focuses, instead, on individual employees and organisations. I integrated my critical review of the organisational work/life balance literature with concepts in the feminist literature, most importantly the gendered public/private divide, to create an explicit ‘gender lens’ which guides the interpretations of my findings. I applied this gender lens to Habermas’ model of societal evolution to operationalise it as an analytical tool for this research. From this theoretical basis, I designed a comparative research project, using Australia and Sweden as country case studies, which compares the approaches to work/life balance in the two countries. The focus of the analysis is on parental leave as one important example of work/life balance policies. The data for this research includes the parental leave legislation, public documents released by governments and associated bodies as well as national surveys on the take-up of parental leave provisions in both countries. This material is analysed in the light of the conceptual framework. [...]

Conducting suicide research in Australia in relation to the operation of Human Research Ethics Committees

- Type: Text , Thesis , PhD
- Full Text:
- Description: This thesis began with a research project on suicide that was abandoned after many hurdles were encountered in terms of reaching participants and after various applications to ethics committees. The ultimate research question was then recast as ‘Do Human Research Ethics Committees influence the conduct of suicide research in Australia?’ The conceptual framework for setting up the research was derived from literature on Critical Theory, Feminism and Weberian concepts of power and rationality. Subsidiary questions were then derived from this literature and the starting exemplar case of my own research attempts. These considered whether suicide research was problematic for ethics committees, the nature of the experiences of ethics committee members in making decisions regarding suicide research and whether the influences of disciplinary background, patriarchal medical dominance and pro-positivism were evident. In addition, questions were raised about whether and how other researchers who sought approval to conduct research into suicide-related issues were appraised. [...]

Becoming "Brave and Gallant" : Decolonising the myths of Burke and Wills; Cross-cultural exchanges and the co-production of knowledge during the Victorian Exploring Expedition and the subsequent Relief Expeditions
- Authors: Jeffries, Peta
- Date: 2015
- Type: Text , Thesis , PhD
- Full Text:
- Description: The history of the Victorian Exploring Expedition (VEE), also known as ‘Burke and Wills’, has commonly been told as a story of ‘brave and gallant men’ who ventured into an unfamiliar landscape and became victims of the ‘ghastly blank’ interior of Australia. Visual artists and historians have memorialised these men as solo-hero explorers who sacrificed their youth and life potential for the sake of Australian nation. The myth of Burke and Wills is a constructed narrative and symbol of glory and achievement that denies the involvement of significant others in exploration and geographical knowledge creation. The path the VEE created through the centre of Australia opened up the broader continent for rapid colonisation and imperial expansion. The tragic legacy of the deaths of Burke and Wills is part of the Australian identity, however, some major aspects of the VEE successes and failures have been sidelined, silenced and even completely ignored in many historical accounts. The historical and visual art accounts that contributed to the memorialisation of Burke and Wills often denied the involvement of other exploration team members, the relief expeditions who went in search of the missing explorers, various intermediaries, guides, go-betweens and significantly Aboriginal peoples’ close involvement and or resistance to interior exploration. Yandruwandha people have been remembered as a friendly and accommodating community who assisted the explorers in their last days and who cared for John King. Within the archives and social memories are examples of agency, power, resistance, and varied perspectives of Burke and Wills. This ethnographic history asks why relations between the explorers, Aboriginal peoples and landscape have been told the way they have and provides examples of encounter and exchange, mutual adaptation and the co-production of knowledge as a way to decolonise the myths of Burke and Wills.

International students and social connectedness : The role sport can play
- Authors: McLeod, Beth Lauren
- Date: 2015
- Type: Text , Thesis , PhD
- Full Text:
- Description: Whilst it is well known that international education is a lucrative industry, what is not so well known is how to continue attracting prospective higher education students to Australia in what has become a competitive global market. Adding concern to Australia’s reputation as an international education provider is the recent research which indicated that international students are dissatisfied with their social experiences while in Australia. This research highlights that international students in Australia are not getting the most value out of their educational sojourn, in part, because of their less than engaging experiences with Australians. As a consequence, one of the main challenges faced by Australia’s international education sector is to create and sustain a positive student experience in order to enhance Australia’s reputation as an education provider, be fair to the students and remain competitive in this valuable industry. Developing stronger social connections appears to be an important factor for creating a positive international student experience, and a case can be made to consider the role of sport as a potential strategy for enhancing the international student experience. In particular, sports participation and spectatorship may be possible vectors for enhancing international students’ social connections with Australians because of the opportunity provided for personal interaction. To date, there is a relative lack of research that has investigated this relationship. This Australian-based study aimed to bridge this knowledge gap by focusing on three key areas: (1) to determine whether there was a relationship between sports participation and social connectedness, and if this relationship was influenced by the students’ type and level of sports participation; (2) to determine whether there was a relationship between sport spectatorship and social connectedness, and if the context of sport spectatorship influenced this relationship; and, (3) to determine whether there was a relationship between sport spectatorship and sports participation, particularly from the perspective of international students in Australia. ii The investigation used a mixed methods approach, which combined quantitative and qualitative data collection and analysis, in a sequential manner. The first phase involved the collection of questionnaire data. Subsequently, these quantitative findings were used to frame the qualitative interview themes and foci. Through this process, greater depth and personal perspectives were added to the initial findings to enrich understanding of various elements of the investigation. Qualitatively the overarching premise as to why a quantitative relationship existed between sports participation and social connectedness (p<0.0001) was that sporting involvement enabled close proximity to the Australian people, who the students perceived to be highly active in sport. The qualitative findings also supported the quantitative finding for the second research sub-question indicating that spectatorship was related to social connectedness (p<0.0001). According to the qualitative results spectatorship was deemed to be one of the best ways for students to connect with Australian people. The students explained this was possible because spectatorship provided them with an easy and relaxed way to connect to people, particularly Australian people and in a casual environment. Three underlying themes explained why spectatorship was perceived to provide this unique environment and connection opportunity. These were (1) spectatorship is a universal and inclusive leisure activity; (2) spectatorship connects people; and (3) Australia has a strong sporting culture. The quantitative results from the third research sub-question revealed a relationship between spectatorship and sports participation (p<0.0001) and the qualitative interview data enriched this finding. The interview data indicated that students considered spectatorship as a driver for their sports participation. Students revealed that spectatorship helped them increase their level of sports participation, and to feel included in sport even without physical involvement. The qualitative results from this study suggest spectatorship plays a more important role than sports participation for international students in developing social connections with Australian people. Results revealed that increased involvement in sports participation and spectatorship enhanced students’ understanding of the Australian language and culture, assisting them iii to develop and maintain meaningful friendships in their host country. This finding indicates that sport may be a unique way for international students to achieve the connections they desire with Australians. The value of both sports participation and spectatorship for international students is evident. Accordingly it is recommended that Australian educational institutions offer sporting opportunities specifically for international students, and thus contribute positively to a rewarding and lasting educational experience.

The qualitative findings also supported the quantitative finding for the second research sub-question indicating that spectatorship was related to social connectedness (p<0.0001). According to the qualitative results spectatorship was deemed to be one of the best ways for students to connect with Australian people. The students explained this was possible because spectatorship provided them with an easy and relaxed way to connect to people, particularly Australian people and in a casual environment. Three underlying themes explained why spectatorship was perceived to provide this unique environment and connection opportunity. These were (1) spectatorship is a universal and inclusive leisure activity; (2) spectatorship connects people; and (3) Australia has a strong sporting culture. The quantitative results from the third research sub-question revealed a relationship between spectatorship and sports participation (p<0.0001) and the qualitative interview data enriched this finding. The interview data indicated that students considered spectatorship as a driver for their sports participation. Students revealed that spectatorship helped them increase their level of sports participation, and to feel included in sport even without physical involvement. The qualitative results from this study suggest spectatorship plays a more important role than sports participation for international students in developing social connections with Australian people. Results revealed that increased involvement in sports participation and spectatorship enhanced students’ understanding of the Australian language and culture, assisting them iii to develop and maintain meaningful friendships in their host country. This finding indicates that sport may be a unique way for international students to achieve the connections they desire with Australians. The value of both sports participation and spectatorship for international students is evident. Accordingly it is recommended that Australian educational institutions offer sporting opportunities specifically for international students, and thus contribute positively to a rewarding and lasting educational experience.

A conceptual re-alignment of methodology underpinning tax effect accounting : An Australian exploration of the contemporary normalising effect
- Authors: Morton, Elizabeth
- Date: 2016
- Type: Text , Thesis , PhD
- Full Text:
- Description: This research examines the presence and effectiveness of the ‘normalising effect’, traditionally offered as the main justification for tax effect accounting’s (TEA) adoption. TEA can be seen as a technical facet of accounting practice, ‘normalising’ the timing differences between the accounting and taxation systems. That is, income tax is recognised according to when transactions are recognised for accounting purposes in order to ‘normalise’ reported profits, thereby reflecting an income statement focus. It has been contended that this will improve the usefulness of financial reports by ‘correcting’ misleading and ‘unreal’ fluctuations in income tax. Australia’s adoption of AIFRS in 2005 entailed a major conceptual re-alignment of the methodology underpinning TEA, moving away from the income statement focus in favour of a balance sheet focus. This implied a different normalisation emphasis. It is within this contemporary setting, based on a study of 90 companies over the two regulatory periods between 2002 and 2011 (AGAAP and AIFRS), that a quantitative measure of the presence and effectiveness of the normalising effect was undertaken, additionally considering the subsequent balance sheet impact. Effective normalisation was revealed during the AGAAP period, whilst only effective after the removal of loss makers during the AIFRS period. These findings suggest that the relaxation of recognition criteria under AIFRS may have had a meaningful impact on the effectiveness of the new standard. However, when normalisation was given a more narrow definition in light of prima facie tax, deferred taxes had a more substantial impact, particularly during the AIFRS period. Such findings are consistent with the notion thatTEA enables reported tax to be ‘as if’ it were a function of accounting, without a substantial build up on the balance sheet as a consequence. These findings have implications for evaluating the efficacy of TEA and comprehending the nature of contemporary financial statements.

Assessing productive soil - landscapes in Victoria using digital soil mapping
- Authors: Robinson, Nathan
- Date: 2016
- Type: Text , Thesis , PhD
- Full Text:
- Description: Spatial soil information is used to support questions on agriculture and the environment from global to local scales. Historically, soil mapping has been used to inform and guide a multitude of land users with their decisions. Demand for specific spatial soil information is increasing in response from a wider range of users operating across agricultural and environmental domains. To satisfy these demands, users must be provided with practical and relevant spatial soil information. Novel approaches are required to deal with global deficiencies in available soil information. A major limitation to this is the plethora of incongruent legacy data with poor spatial and temporal coverage. This research study initially identifies the specific needs of users for spatial soil information with a focus on the requirements of biophysical modellers. Secondly, error sources that hamper Digital Soil Mapping (DSM) are identified, described and assessed using pH in practical and relevant examples. A final aim is to spatially predict soil properties (e.g. clay mineralogy) that underpin soil chemical behaviour. This is achieved by harmonising legacy data in combination with new spectroscopy techniques and a spatial inference approach. The spatial soil information needs of biophysical modellers in Victoria, Australia were found to be consistent with global needs for information including soil water characteristics, organic carbon and effective rooting depth. To accommodate stochastic and epistemic uncertainties in spatial soil information, uncertainty frameworks proved effective to deal with, and understand the limitations of legacy data in spatial inference models. Robust and reliable spectroscopic models for properties that are linked to functions and services delivered by soil were achieved and used in 3D spatial models. These findings will enable a tactical response through the delivery of pertinent spatial soil information that is contemporary, quality assured and sought by users. Learnings presented should enable producers of spatial soil information to be more comprehensive in their delivery of products that are easy to use, accessible and understood by a growing user community.

- Type: Text , Thesis , PhD

- Description: This thesis disentangles two elements from the complex interdependent suite of key drivers of firm sophistication in capital-budgeting. Specifically, the relative sophistication of a firm (i.e. its nature) and the development level of the nation in which a firm is embedded (i.e. the nurture experienced by the firm). This research should enhance the development focus and process of nations (e.g., to what degree should national development be about raising the ability of individual firms or will raising national development act as a rising tide [that] raises all boats). The comparative data used in this study comes from 150 Australian (ASX200-index-listed) firms and 150 Sri Lankan (Colombo-stock-exchange-listed firms). The research questions are answered via a quantitative research design that uses primary and secondary data. The response rate to the questionnaire survey of firms was, 45 and 73 completed questionnaires from, respectively, Australia and Sri Lanka (an effective response rate of, respectively, 31.5 and 48.7 percent). Secondary data for 2003-12 are obtained from the ASX, CSE’s and SIRCA databases and are used to calculate return on assets, return on equity, Tobin Q, and earnings per share for the sampled firms. It was found that Australian firms tend to rely heavily on sophisticated capital-budgeting practices, but Sri Lankan relatively small firms prefer simple analysis methods and the larger firms tend to be as adept at sophisticated capital budgeting as their Australian counterparts. The choice of whether to use more sophisticated practices or simpler alternatives varies with a firm’s attributes as well as the level of economic and financial market development in its environment. Also, Australian firms tend to use capital-budget models with good-to-strong predictive power (except for ROE) and Sri Lankan firms tend to use capital-budget models with fair-to-poor predictive power. Further, the analysis of Australian firms tends to yield stronger and more statistically-significant results, than those generated by Sri Lankan firms.

Injury epidemiology among Australian female cricketers
- Authors: Perera, Nirmala
- Date: 2016
- Type: Text , Thesis , PhD
- Full Text:
- Description: Cricket is a male-dominated sport; however, its popularity among females is increasing. Like other sports, participation in cricket poses the risk of injury to players. Injury problems for female cricketers are virtually unknown, as studies examining cricket injuries include almost exclusively male participants. In other sports, the types of injuries experienced by men and women are known to be different. Therefore, a clear understanding of the extent and types of injuries sustained by female cricket players is required, to underpin appropriately targeted injury prevention strategies. This thesis provides the first detailed epidemiological profile of cricket injuries sustained by women, by: 1. conducting a systematic review describing injuries in competitive team bat or stick sports in women, to enable cricket injuries to be viewed within the perspective of wider, but relevant, injury data, 2. evaluating existing data sources relating to hospital admissions from Victoria and Queensland and successful insurance claims across Australia, 3. examining the nature and incidence of cricket injuries in elite female players using Cricket Australia’s Athlete Management System, and 4. conducting a nationwide self-report survey of injuries during the 2014–15 season. This PhD research represents participants from different levels of play, across age groups and across Australia. The findings indicate that incidence of injuries for female cricketers were higher than expected based on previous findings in comparable sports, except when considered in relation to insurance claims. The cricket injury rate across hospital presentations, insurance claims, the AMS (Fair Play AMS 2016) and self-reported survey data, each of which represents different level of the sports injury pyramid, identified all-rounders and pace bowlers as having a higher incidence of injury than players in other positions. The highest frequency of reported injuries were in the head, hands, knees and ankles. The nature of the most common injuries were dislocations/sprains/strains, fractures, muscle injury, joint injury and gradual onset injuries. At the elite-level, lumber spine stress fractures accounted for a significant amount of time-loss from the sport. In this thesis, findings from the insurance claims, self-reported survey and AMS (Fair Play AMS 2016) data indicated that most injuries were of a low severity and were more likely to be treated outside of healthcare facilities such as hospitals. In summary, patterns of the most common injuries, in terms of anatomical location and nature of the injuries, were consistent throughout community-level players with some similarities to elite-level players. However, the injury mechanisms and risk factors may differ depending on the level of competition and player’s skill. Recommendations are that ongoing injury surveillance should be conducted at all levels of the sport, and surveillance methodology should be tailored to the specific setting, personnel and available resources. Therefore, before implementing an injury surveillance system at the community-level of the sport, more research is needed to fully understand what type of injury surveillance system might be feasible and suitable in this context.

Investigations into the ecology and management of the invasive plant Galenia pubescens within the native temperate grasslands of Victoria, Australia
- Authors: Mahmood, Ako
- Date: 2016
- Type: Text , Thesis , PhD
- Full Text:
- Description: Plant invasions of natural ecosystems are one of the major threats to the conservation of biological diversity across nearly all biogeographical regions in the world. This thesis focuses on Galenia pubescens (Carpet weed) as a case study of possible approaches to the potential management of environmental weed species. G. pubescens is a woody prostrate perennial plant that is becoming a serious threat to Australian temperate grasslands, surrounding agricultural areas and conservation reserves. It is indigenous to South Africa and was first recorded in Australia in the early 1900s, and it is an aggressive competitor against native species. It is difficult to control, and little information exists about its effects on natural ecosystems, and aspects of its biology and ecology. This study has investigated some important ecological characteristics of G. pubescens’ seeds and has experimented with different management strategies in combination with chemical control. It has also considered the potential for the expansion of the distribution of this species across suitable habitat in Australia under predicted elevated CO2 and drought conditions. Seeds of G. pubescens are shown to be able to germinate over a broad range of temperatures, but short bursts (5 minutes) of high temperatures (80oC to 120oC replicating possible exposures to a fire) reduced seed germination. Seed germination was positively favored by light and declined rapidly in darkness, decreasing by > 80% at a depth of only 0.5 cm in soil. This suggests that fire regimes might be useful in removing mature plants and controlling seed numbers on the surface, and that subsequent native seeding of undisturbed areas may assist in the long-term management of this noxious weed. A trial was conducted to determine the effect of treatment with a plant essential oil (pine oil) to limit the seed germination and seedling emergence of G. pubescens. This trial showed that the effects of pine oil application were significant (P<0.05). Germination was completely inhibited by application of pine oil at 5% or higher concentrations directly to seeds, and seedling emergence was reduced by between 90 and 100% in pot trials. These outcomes demonstrate the potential viability of pine oil as a long-term control option for this species. In field-based experiments, control strategies including herbicide control with glyphosate, organic herbicide control with pine oil, the application of mulch, and the addition of native seeds to the available seedbank (and all possible combinations of these techniques), were tested. The study showed that one single treatment of a G. pubescens infestation without undertaking a secondary treatment is insufficient to control the G. pubescens infestation or to encourage native regeneration, but that a combined strategy, employing all the aforementioned techniques, is more effective. It is however suggested that full regeneration of the area may not be possible unless further restoration programs are instituted after the cycle of G. pubescens’ treatment has been completed. The thesis also assessed the control effects of chemical control combined with a prescribed spring burning. Assessment of the resulting aboveground vegetation of G. pubescens has shown that a combination of chemical control and late-spring burning can reduce the cover of non-native species such as G. pubescens, suggesting that this could be a useful tool in their management. Finally, this study has supported the view that the growth of G. pubescens will be significantly enhanced in a future climate with an enriched atmospheric CO2 concentration. These climatic changes will have important implications for management of this noxious weed in the future.

Managing risk and enhancing corporate sustainability in the Australian extractive sector : An exploratory study of leading mining and oil & gas firms in Australia
- Authors: Andeobu, Lynda
- Date: 2016
- Type: Text , Thesis , PhD
- Full Text:
- Description: Risk is an unavoidable issue in most activities of life, including business. Risk-management is increasingly a hot-button issue for stakeholders and the general public. As such, it is of rising importance in the high-risk extractive industries of mining and oil & gas. Specifically, risk-management can help firms reduce business failure-rates and enhance corporate sustainability. However, the integration of risk-management and corporate sustainability within planning, financing, and operations remains a key challenge for the sector. This research seeks to fill this gap by investigating and evaluating the current use of risk-management by extractive-sector firms to add value to stakeholders. Given that risk- management and its impact on corporate sustainability is enormous, this study will provide useful insights into the risk-management practices undertaken by extractive-sector firms in Australia and how cost-effective risk-management practices contribute to the overall enhancement of financial performance, stakeholder value and corporate sustainability of those firms. This study, after drawing data from Australia’s top 10 mining/metals firms and top 10 energy/utilities firms, uses: i) Questionnaires to give a background/context for the study, and ii) Interviews to further probe issues raised and gain a deeper understanding. The analysis in this study found that risk-management practices are: i) Perceived by management practices to contribute significantly to financial performance, stakeholder value and corporate sustainability of their firms ii) Very similar across mining firms and those in oil & gas, and iii) Too limited in application in the extractive-sector and should be extended beyond traditional hazards. Overall, it was found that risk-management systems appear to be comparable across Australia’s large mining firms and oil & gas firms. However, at a detailed level, these basic systems and structures of risk-management are adjusted and adapted to meet specific needs, corporate strategies, organisational objectives and environmental pressures. NOTE: At the request of the author, Chapters 2-12 and Appendix 7 have been removed.
