- Description: High penetrations of inverter-based renewable resources (IBRs) diminish the resilience that traditional power systems had due to constant research and developments for many years. In particular, dynamic voltage stability becomes one of the major concerns for transmission system operators due to the limited capabilities of IBRs (i.e., voltage and frequency regulation). A heavily loaded renewable-rich network is susceptible to fault-induced delayed voltage recovery (FIDVR) due to insufficient effective reactive power (E-VAr) in power grids. Hence, it is crucial to thoroughly scrutinize each VAr resources' participation in E-VAr under various operating conditions. Moreover, it is essential to investigate the influence of E-VAr on system post-fault performance. The E-VAr investigation would help in determining the optimal location and sizing of grid-connected IBRs and allow more renewable energy integration. Furthermore, it would enrich decision-making about adopting additional grid support devices. In this paper, a comprehensive assessment framework is utilized to assess the E-VAr of a power system with a large-scale photovoltaic power. Plant under different realistic operating conditions. Several indices quantifying the contribution of VAr resources and load bus voltage recovery assists to explore the transient response and voltage trajectories. The recovery indices help have a better understanding of the factors affecting E-VAr. The proposed framework has been tested in the New England (IEEE 39 bus system) through simulation by DIgSILENT Power Factory. © 2013 IEEE.

- Description: Individual differences in the stress response have been linked with numerous factors, including personality traits and mindfulness. Selye (1950) was among the first to detail the physiological stress response that takes place during a stressful event, or after exposure to a stressor. These responses include heart rate changes and the secretion of cortisol into the blood stream, which are key physiological indicators that a stress response is taking place. Lazarus and Folkman (1984) examined appraisal of stressful events, determining that this is crucial to the stress experience. An extension of Lazarus and Folkman’s cognitive appraisal theory was offered by Vollrath (2001), suggesting an individual’s personality accentuates our stress response, therefore, offering an explanation for the individual differences evident in stress responses. The relationship between personality and stress is not straight forward, and other factors, such as affect and mindfulness, may influence this relationship. Thus, this dissertation is divided into three studies. Study 1 examined the moderating and mediating factors of affect on the relationship between personality traits and perceived stress. A total of 290 adults (71% female; Mage = 35.0 years, SD = 12.92) completed an online questionnaire package, comprising of the Perceived Stress Scale, Big Five Inventory, Positive and Negative Affect Schedule, and a number of demographic questions. A hierarchical regression showed that 56% of the variance in perceived stress was explained by personality and affect, and when all personality traits were viewed concurrently and with affect, neuroticism was the only one to significantly explain variance in perceived stress. No moderation effects were found in Study 1 however, positive affect partially mediated the relationship between neuroticism and perceived stress. Study 2 aimed to further the findings of Study 1 by investigating whether trait mindfulness impacted the relationship between personality and stress. A total of 266 adults (70% female; Mage = 34.0 years, SD = 12.68) completed an online questionnaire package, consisting of the Perceived Stress Scale, Big Five Inventory, and Carolina Empirically Derived Mindfulness Scale. A hierarchical regression showed that 58% of the variance in perceived stress was explained by personality and trait mindfulness. When all personality traits and trait mindfulness were viewed together, neuroticism and agreeableness were the only personality traits to significantly explain variance in perceived stress. The sub-scale trait mindfulness attention significantly moderated the relationship between agreeableness and perceived stress, while a partial mediation was found between neuroticism and the sub-scale trait mindfulness acceptance. Study 3 investigated the effectiveness of a brief state-based mindfulness intervention on physiological (cortisol and heart rate) and psychological stress responses, in a participant matched design. A total of 20 participants (60% female; Mage = 34.60 years, SD = 14.68) were recruited from Studies 1 and/or 2 and matched based on gender, dominant personality trait (found in Study 1 and 2), and perceived stress. One participant in each matched pair was then randomly allocated to the mindfulness experimental, or control, group. The mindfulness experimental group completed a 10-minute breathing exercise, prior to completing the Trier Social Stress Test, a verbal presentation and arithmetic task, designed to induce stress. The control group did not complete any activity prior to the stress test. Comparison of the groups indicated that no significant differences in perceived stress were evident pre-post- intervention. Changes in heart rate were noted for all participants during the intervention, though no difference was evident between groups. The results of Study 3 indicate a mindfulness breathing exercise makes little difference to physiological stress responses during a stress task. The combined findings of this dissertation indicate that personality traits can influence the likelihood of an individual experiencing stress. Mindfulness and affect also impact on the relationship between personality and stress and offer some insight into the individual experience of stress responses.

- Description: Post-implementation amendments to ERP systems (ERP-PIA) are of importance for advancing ERP research, but more importantly essential if ERP systems are to be used as a strategic and competitive business tool. For ease of clarity, we have adopted the term “amendments” to encompass the main forms of post implementation activities: maintenance, enhancements and upgrades. The term “amendments” is used to counteract one of the major findings from this research - the inconsistency of terms used by many authors to explain post implementation activities. This paper presents a review of the ERP post-implementation amendment literature in order to provide answers to two specific questions: first, what is the current state of research in the field of ERP-PIA; and second, what are the future research directions that need to be explored in the field of ERP-PIA. From the review, we develop a framework to identify: (a) major themes concerning ERP post-implementation amendments, (b) inherent gaps in the post-implementation amendments literature, and (c) specific areas that require further research attention influencing the uptake of amendments. Suggestions on empirical evaluation of research directions and their relevance in the extension of existing literature is presented.

- Description: Climate change, energy security, pollution and increasing unemployment in the face of automation are four critical challenges facing every region in the twenty-first century, including the Latrobe Valley in Victoria, Australia. The Valley – location of the largest brown coal deposits and forest industry in the southern hemisphere – is undergoing unprecedented and rapid changes. Its ageing brown coal power plants are retiring and replacements are not planned, leading to job insecurity. Solutions are needed that ensure continued economic activity in the region whilst allowing for the Valley to contribute its fair share in the fight against the climate change. The aim of this study is to investigate a possible local solution that could help tackle these issues of the Latrobe Valley in addition to plastic pollution and energy insecurity. Transitioning from linear to circular materials flow is one possible solution that favours sustainability and job security. Consequently, a multiproduct succinic acid biorefinery is modelled, acting as an industrial hub in a potential Latrobe Valley circular economy. This allows for employment creation in the value-addition of its platform chemicals into carbon negative and environment-friendly products. Additionally, such a biorefinery concept has the capacity to tackle Post-combustion CO2 Capture (PCC) industry’s wastes. It is anticipated that any future utilisation of brown coal as an energy vector would entail PCC to ensure carbon neutrality. A PCC industry produces CO2 and amine wastes that require adequate disposal. The modelled biorefinery has the capacity to valorise both. The simulation and the techno-economic analysis show the modelled Carbon Negative Biorefinery consumes 656,000 metric tonnes (t) of pulp logs and 42,000 t of CO2 to produce 220,000 t of succinic acid, 115,000 t of acetic acid and 900 t of dimethyl ether, annually. Biorefinery’s CAPEX and OPEX stand at AU$ 635,000,000 and $ 180,000,000 respectively. The calculated Minimum Selling Price for succinic acid is $ 990/t, only 6.4% higher than a typical biorefinery. Subsequently, biorefinery’s capacity as an anchor tenant is also simulated via technical evaluations of four value-added products: • Poly(butylene succinate) as biodegradable polymer replacing petro-plastics – simulation results show 1 t of succinic acid produces 0.19 t of tetrahydrofuran and 0.44 t of poly(butylene succinate); • Carbon fibre for insulation products, sporting goods and foams – 1 t of lignin and 0.8 t of acetic anhydride produce 0.8 t of carbon fibre; • Succinylated lignin adhesive for replacing urea-formaldehyde in the wood industry – simulation results show the biorefinery concept having the capacity to valorise both waste amine and CO2 from a PCC plant; and • Renewable fuels like hydrogen as energy vectors – a small biorefinery can potentially provide dozens of gigawatt hours of stored power for backup and peak demands, annually. In summary, results of this research are: • A biorefinery can valorise PCC plant wastes; • Multiproduct succinic acid biorefinery is economically viable; • Renewable fuels are ideally suited as energy storage vectors for a renewable energy grid both in developing and developed countries; • Bioproducts can reduce CO2 emissions thereby mitigate climate change; • Bioproducts can replace petro-products and reduce pollution; • Bioproducts can replace construction industry materials associated with CO2 emissions; • Biorefineries can help a region transition from a linear to a circular economy; and • Circular economies have the potential to generate secure jobs. In conclusion, this research identifies platform biochemicals as potential key drivers in a linear economy’s transition to a circular economy.

- Description: In this study, a novel biorefinery concept producing carbon fibre-poly(butylene succinate) composite foam (CPC foam) from lignocellulose and CO 2 is modelled. The biodegradable nature of poly(butylene succinate) would allow for easy carbon fibre recovery from the CPC foam for reuse at the end of product lifecycle, thus allowing for a circular materials flow. Technical simulation results show the biorefinery consumes 417 kg of biomass, 33 kg of CO 2 , 86 kg of methanol, 23 kg of acetic anhydride, 130 kWh of electricity and 1166 kW of heat per hour. The facility generates 72 kg of CPC foam, 82 kg of carbon fibre, 24 kg of tetrahydrofuran and 50 kg of dimethyl ether (DME). DME is used to fulfil parasitic electricity requirement. These results demonstrate the technical viability of this biorefinery although, research is needed to reduce parasitic energy demand. This carbon negative biorefinery avoids carcinogens and halogens for polymeric materials synthesis by utilising green chemistry principles and lignocellulose feedstock.

Data were collected via unstructured interviews with four fathers. Analysis followed the procedural steps for phenomenological data as outlined by Colaizzi (1978). Fathers described their experience of living with their chronically ill child as being filled with progressive losses for themselves and their child, including loss of: 1) pre-conceived expectations of future life; 2) a normal parenting relationship with their child; 3) normal partner relationship; and, 4) control of time and freedom. Findings contribute to knowledge and understanding of the complex nature of fathering a chronically ill child in rural Australia.

- Description: Work exhibited at Counihan Gallery, Brunswick, Melbourne Inspired by an Australia Council residency in Rome in late 2009, Soul /Skin/Space explores the potential for bodily metaphors to be found in the physical environment - whether by overt reference, inferred likeness, or merely a trace left behind by the imprint of a hand or foot. In Rome there exists the incredibly powerful sense of human presence and a profound history in the depiction of the human form. The body is everywhere, both living and dead, flesh and stone, in the museums and galleries, on the streets, the aqueducts and fountains. The city itself is a living, breathing entity, an ancient being possessing the wisdom and knowledge borne out of three thousand years of experience. It has loved and lost, been abandoned and left others behind, lived through riches and poverty, triumphs, defeats and tragedies. Glimpses of faces and figures evoke memories of a once vigorous and youthful body now aged and weary. And monumental fragments of stone and marble are like broken bones and worn teeth, the relics of a once revered individual now almost reduced to dust.

- Description: This article provides an analysis of the issues and ethical challenges faced in a study with LGBTIQ student participants concerning their experiences of violence, harassment and bullying in tertiary settings. The authors detail the ethical challenges behind the development of the project, and around conducting research with a minority and vulnerable population. The article illustrates how the utilization of feminist and queer theory has impacted the process of conducting ethical research, including approaches to recruitment and participant autonomy. The dilemmas of confidentiality within a self-labelled and easily identifiable population are resolved. Further, unexpected challenges and risks to participant safety created through adherence to institutional ethical research frameworks are rectified. Importantly, the authors seek to avoid revictimization of participants and to instead empower students in their responses to violence, harassment and bullying that they may have experienced. The authors point to utilization of theoretical foundations and continual reflexive improvement as elements of best practice for those seeking to research minority populations, and in projects marked by the participation of those deemed vulnerable and high-risk. © 2016, © The Author(s) 2016.

- Description: The application of true cost accounting (TCA) at farm level requires a common framework and metric for measuring, capturing and valuing sustainability. We propose such a framework and farm metric that build on the four capitals—natural, social, human and produced—that are essential for sustainability. The framework is developed by reviewing the scientific and technical literature on various approaches and tools that have been used to measure farm sustainability. We use quantifiable aspects of sustainability in the farm metrics. The farm sustainability metrics comprise four capitals with 11 categories and 33 indicators. These indicators can be assessed using bio-physical assessment, descriptive or quantitative methods. Once this information is compiled for a farm, then some of the categories can be monetised to reflect all the costs and benefits of using state-of-the-art TCA. There is a need to establish benchmarks and standards for each of the four types of capitals and indicators for the comparison of food systems. We believe the use of this comprehensive framework and farm metrics will help to correct several deficiencies of the current food system. We conclude by highlighting the benefits and limitations in the use of farm metrics. Measuring all positive and negative externalities at farm level can shift global food systems towards sustainability. Copyright: © 2021 by the authors. Licensee MDPI, Basel, Switzerland.

- Description: Global agriculture aims to minimize its impacts on environment and human health while maintaining its productivity. This requires a comprehensive understanding of its benefits and costs to ecosystems and society. Here, we apply a new evaluation framework developed by the Economics of Ecosystems and Biodiversity for Agriculture and Food (TEEBAgriFood) to assess key benefits and costs on the production side of genetically modified (GM) and organic corn systems in Minnesota, USA. The market value of GM corn is $4.5 billion, and only $31.8 million for organic corn using production data and market prices of 2017. GM corn generates revenue of $1488 per hectare (at $121 per MT), which is significantly lower than the organic corn at $2793 per hectare (at $294 per MT). Using a novel three-stage wellbeing valuation, analysis of the associations between corn production intensity and subjective measures of general health and wellbeing indicates that the total non-financial health cost associated with GM corn is $427.50 per hectare or $1.3 billion annually. We also find that the total annual environmental cost associated with GM corn production is $179 per hectare or $557.65 million within Minnesota. The use of the evaluation framework can help to improve decision making at farm and policy level to develop sustainable agriculture in order to minimize environmental and health related costs to society and economy. © 2020, The Author(s). **Please note that there are multiple authors for this article therefore only the name of the first 5 including Federation University Australia affiliate “Harpinder Sandhu” is provided in this record**

- Description: The global agenda for sustainable development includes the alleviation of poverty and hunger by developing sustainable agriculture and food systems. Intensive farming systems and its variations, such as sustainable intensification or ecological intensification, are currently being pro-moted as technologies that can improve agricultural productivity and reduce environmental im-pacts. However, these are focused only on per-hectare productivity with growing negative impacts on local culture and the environment. This study identifies the negative impacts of crop-and live-stock-based farming systems on the Indo-Gangetic plains, as well as in the USA, China, and South America as an example of key challenges in global agriculture. These impacts are classified into environmental, social, economic, and health impacts. An alternative paradigm is proposed to over-come some of the shortcomings of current global agriculture. This new bottom-up paradigm is based on three indicators that are fundamental to achieve the environmental, economic, and social sustainability of agriculture and food systems. These are divided into technical, geographic, and social indicators and have been analysed for four farming systems—low-input, high-input, organic, and desired farming systems. Seven global geographic regions have been analysed in terms of their socio-economic indicators and status of agriculture in order to develop pathways for the implementation of the new paradigm. The pathway for change suggested in this paper includes a focus on research and training, policy and institutional changes, and an evaluation of the costs and benefits, and changes in production models that consider scale and sustainability metrics and include inno-vations in consultation with all stakeholders. This new paradigm has the potential to direct global efforts towards more local and regional solutions, which are community driven and constitute a ‘bottom-up’ approach. © 2021 by the author.

- Description: One of the major consequences of expansive urban growth is the degradation and loss of productive agricultural land and agroecosystem functions. Four landscape metrics-Percentage of Land (PLAND), Mean Parcel Size (MPS), Parcel Density (PD), and Modified Simpson's Diversity Index (MSDI)-were calculated for 1 km × 1 km cells along three 50 km-long transects that extend out from the Adelaide CBD, in order to analyze variations in landscape structures. Each transect has different land uses beyond the built-up area, and they differ in topography, soils, and rates of urban expansion. Our new findings are that zones of agricultural land fragmentation can be identified by the relationships between MPS and PD, that these occur in areas where PD ranges from 7 and 35, and that these occur regardless of distance along the transect, land use, topography, soils, or rates of urban growth. This suggests a geometry of fragmentation that may be consistent, and indicates that quantification of both land use and land-use change in zones of fragmentation is potentially important in planning. © 2017 by the authors.

Three case studies are presented to explore the uptake of ICT in a regional and rural context. A common element in each of these initiatives is the active participation of the University of Ballarat throughout all project phases. The resultant combination of on-the-ground leadership, infrastructure, collaboration and multi-disciplinary research has not only created benefits for the individual communities but also through the generation of consultancy income, publications and community engagement of a type which is highly consistent with the University’s vision and mission.
