  • Description: Impacts of tropical cyclones in the South Pacific Island countries are of great significance. Now with the growing threats from human-induced climate change, the need for effective disaster risk management and adaptation strategies for these island countries is more important than before. In order to implement appropriate strategies, a comprehensive understanding of South Pacific tropical cyclone activity—and how it is likely to change as a result of human-induced climate change—is essential. While a number of past studies have examined various aspects of tropical cyclone activity in the South Pacific basin, a review that consolidates those studies with new information is essential. In this chapter, we first examine tropical cyclone data quality for the South Pacific basin and then review the robustness of the relationship between South Pacific tropical cyclones and drivers of natural climate variability. Note that an understanding of the limitations of the data quality is important to determine the extent of natural climate variability and signatures—if any—of human-induced climate change on tropical cyclones. We then examine the influence of climate change on tropical cyclones using up-to-date historical observations and climate model projections. © Springer Nature Switzerland AG 2020.

  • Description: The International Labour Organization characterises being young in today's labour market as 'not easy'. In parts of Gippsland, a regional area of Victoria Australia, it is certainly not easy because youth unemployment reached 21.7% in 2016, the second highest in the state. Within this regional-global context, research into youth aspirations is often bounded by a deficit-focused framework with little emphasis on contextual positives. This chapter, however, reports on a 5-year project of an innovative regional school-industry partnership. 'Broadening Horizons' provides project-based workplace learning units where partners immerse students in 'realworld problems' such as road safety and public transport. The Gippsland regional office of the Department of Education sought a formal evaluation of the project from the local university, at the time Monash Gippsland, but in 2014, we became part of FederationUniversity Australia. This chapter outlines findings from a mixedmethodology evaluation of the project's pilot stage and points out a number of important factors. These include a broader understanding of youth career support, youth aspirations and education/industry partnerships in a regional context, and the importance of involving parents. One school, in particular, achieved very successful parental involvement, which had a major impact on the learning and engagement of the students involved.We conclude that projects like this help to illustrate the complexities associated with youth aspirations in a regional context and may help to challenge associated, unsubstantiated stereotypes. © Springer Nature Singapore Pte Ltd. 2019.

  • Description: For educators and educational researcherswho value democracy and planetary sustainability, our times present pedagogical challenges. The (re)emergence of populism, alt-right violences and the pressing climate crisis, among other global matters, present a dilemma. How do we simultaneously foster the will to form generous, ethical, judgements and actions in students, while meeting their immediate needs and themyriad curricula and governance demands placed on schools, from the context of local circumstances? In response, Susan, a Federation University Gippsland Education (FUGuE) researcher; Gabbi a principal/teacher; Sophie a part-time teacher; and a year's 4-6 class, embarked on a yearlong project to seewhat might be possible from the context of a relatively isolated and tiny Victorian government primary school in the rural/coastal area of SouthGippsland, on the southern coast ofmainland Australia. Together, in a new partnership, we aimed to simultaneously expand students' oral language experiences while cultivating an 'encompassing ethic', an idea from Sue's doctoral thesis. This is the will and capability to visit standpoints of others-human, non-human, past, present and future-in order to encompass the widest possible range of perspectives before forming judgements, speaking and acting. We synthesised this 'going visiting' with the Speaking and Listening mode, and the Ethical Capabilities area of the Victorian Curriculum. The project emerged as a productively and inspirationally transformative one for many of us. So, this chapter reflects on and theorizes the factors that produced transformational possibilities from a small rural school, which enacted its motto of Little School, Big Heart. © Springer Nature Singapore Pte Ltd. 2019.

  • Description: The transformation of teacher educator practice and the implications for practitioner research for a Federation University Gippsland Education (FUGuE) academic are explored in this chapter. It centres on a 'service-learning' partnership that endeavours to reduce inequality by engaging local pre-service teachers and promoting quality education at the primary and tertiary level, which is a United Nations Sustainable Development Goal to which I respond. This study explores my transformational journey from being involved in such partnership opportunities. Prompted by the particulars of place-in this case, some community needs in central Gippsland-and a school-based service-learning partnership with a philanthropic organisation, I consider how my pedagogy, practice and opportunities for research have been enriched. Using a self-study methodology, I analyse how the project aligned with the six elements of Fink's Significant Learning Framework to provide a detailed description of the learning, the critical nature of academic reflection and the impact on personal growth in relation to my involvement. In addition, my practice is examined by collecting anecdotal data from Pre-service Teachers (PSTs) indicating how they connected theory with practical application. To gain nuanced insights around the impact on the learning of PSTs and the author, the self-study utilised research methods such as recording conversations, critical reflection and anecdotal observations. This collection of data was analysed for emerging themes structured around the theoretical framework. The chapter shares my insights as indicated by the transformation of practice as a reflective practitioner and researcher. © Springer Nature Singapore Pte Ltd. 2019. All rights are reserved.

  • Description: Despite the progress of the field of corporate social responsibility (CSR) in recent decades, the knowledge of CSR has been very limited in hospitality and tourism industry in general and in hotel industry in particular. A literature search revealed that scholarly research in the area of CSR in hotel industry began in mid-2000 and it has grown in recent years. However, there has been no review of literature conducted covering CSR issues exclusively in hotel industry. Given the growth of publications in CSR research in hotel industry, it was felt that a content analysis of research would be valuable to scholarship. The present study aims to contribute to this end by presenting a review of articles published in scholarly journals until mid-2017. The findings suggest that the initial focus of CSR research in hotel industry was in the area of CSR practices (economic, social and environmental), impact and importance of CSR, perceptions of CSR by consumers and managers. Interestingly, with the growth of research in recent years, the focus has shifted more towards CSR communication/reporting, green/environmental responsibility and sustainability area. This paper is perhaps the first content analysis of CSR research in hotel industry—an industry that is often blamed for irresponsible use of environmental resources and hence responsible for environmental un-sustainability. It is envisaged that this paper will stimulate further research into CSR in hotel industry and therefore to contribute to advance the field.

  • Description: The lived particulars of Gippsland, the region, the land, the people and all life, are the heart and impetus of Federation University Gippsland Education (FUGuE) researchers, the chapter and collection authors. To us, Gippsland is portentous as both a wonderful place and prophetic of the transformations required for a sustainable and just regional-global future. The Latrobe Valley, for example, home of our small, new, regional university campus, is both bucolic rural locale and site of several coal-fired power stations. For many years, non-Indigenous residents enjoyed a fairly self-contained place of financial and intergenerational security.However, decades of seismic shifts have written new layers of trauma onto the Gippsland palimpsest that began with European invasions.With global imperatives to transition to a low-carbon economy, Gippsland is a canary in the global coal mine. Assertively locating our research in this region, we address moral and institutional imperatives to act as agents in generating a new regional-global modus vivendi from hinterland and a range of other minority positionalities. To set the regional scene, we map territorial and ideational incongruences that the toponyms of 'Gippsland' and 'region' conjure.We narrate how FUGuE contrapuntally emerged from this context and argue that through 'word and deed', FUGuE challenges hegemonic positivist and dominant discourses of what counts as notable research. Like a Bach fugue masterpiece in which each voice has intrinsic integrity but in counterpoint transforms into something new, our interwoven research voices of transformative agency through educational research, disruptively reveal our appreciable, but largely underappreciated, 'impact'. © Springer Nature Singapore Pte Ltd. 2019.

  • Description: Researchers conducting studies in communities have long taken an interest in exploring the different merits of positioning themselves as “insiders”, “outsiders”, or “in-betweeners” in relation to their participants. Yet research exploring the role of the researcher as a “critical friend”—a supportive yet challenging facilitator in self-evaluation processes—has not been fully examined. This chapter speaks to the FUGuE element of transformation—which in the present context, I define as a process where structures and forms undergo conversion. The chapter provides my account as a FUGuE researcher of exploring the methodological implications of my research with a small group of teachers at a primary school located in the Latrobe Valley in Central Gippsland. The emergent relationship now informs my teaching and research practices. The discussion draws on a recently commenced longitudinal study exploring teachers’ use of strategies and processes aimed at improving literacy practices—a phenomenon known as capacity building—through collaboration in a professional learning team, within a context of school improvement. Due to a prior connection with the school, I was invited to become a critical friend and active participant as the school initiated a new Professional Learning Team (PLT) in literacy. Informed by recorded conversations from the PLT meetings, my aim was to conceptualize the role and transformative implications of researching as an invited critical friend within a professional community. This chapter contributes to the methodological discourse of educational research by offering a contextualized analysis of the tensions among the notions of trust, credibility, and positionality as a critical friend researcher.

  • Description: This chapter discusses what it means to be an awake student and how you can be an engaged student to take the maximum advantage of the learning environment. It will explore the interrelationship of being an awake student and an awake nurse. Nursing requires constantly observing the situation, being aware of the context of practice, the situation or event in which you are taking part, and the patient in your care in order to make professional nursing decisions. To be successful in learning and practice, you will need to develop the graduate attributes of a nurse. These including being a professional and ethical decision-maker, politically astute situational leader and citizen, socially and culturally aware agent of change, critically reflective thinker adept in clinical reasoning, creative problem-solver, skilled therapeutic communicator, capable interdisciplinary healthcare team member and competent, caring, safe and professional nurse (Federation University Australia 2015). This chapter also provides ideas for how to overcome difficulties and engage in your learning together with ways that will help you to spend effective time in your learning endearvour. It discusses how you can transition to university learning in a way that makes you an equal partner in the learning process towards becoming an independent learner.

  • Description: The focus of this book has been on exploring the key concepts, knowledge and skills that are relevant to contemporary nursing practice, with a strong emphasis on 'meaning-making' - what things really mean; how this meaning is established; why particular knowledge is necessary or important; and how all this informs your road to nursing, your ongoing learning, practice and professional identity-formation and your conception of what it really means to be and act as a nurse. This final chapter weaves together some of the key focus areas that have made up this 'journey', using stories from practice that may provide you with some further insights to guide you on your path to becoming a skilled and experienced nurse. The second part of this chapter will focus your attention on the fact that once you enter the profession as a beginning-level nurse, this is not the end of your journey; it is only the first stage of your career. There are many options and learning opportunities that can further your career and assist you to develop into an expert nurse across a range of settings. The last part of this chapter will focus on how you can contribute to the further development of the nursing profession by role-modelling and promoting nursing, mentoring and supporting others, and developing and sharing your skills and knowledge with new generations of nurses.

  • Description: This paper presents a summary of research which was conducted in developing a new human-like navigation methodology based on the Agoraphilic algorithm. This new methodology is capable of maneuvering robots in both static and dynamically clutter unknown environments. The Agoraphilic algorithm is an "optimistic" navigation algorithm. The algorithm is based on free space attraction rather than repulsion of obstacles for navigation. Therefore, this algorithm directs robots to follow the free space leading to the goal instead of avoiding obstacles. This approach has eliminated many draw backs of the traditional APF algorithm. However, the major limitation of the previously developed Agoraphilic algorithm could only deal with static environment. The new proposed algorithm has successfully extended the capacity of Agoraphilic algorithm to deal with environment cluttered with dynamic obstacles. The new Agoraphilic algorithm uses a tracking and prediction methodology to estimate the path of unknown moving objects. The estimated locations of the moving objects are combined with static object locations in the robot's visible region to generate time-varying free space attractive forces. These time varying forces maneuver the robot to the goal in dynamically cluttered unknown environment without collusions. To demonstrate the algorithm's ability, several simulations were performed. Furthermore, the new algorithm was tested and bench-marked against other APF published work under similar environment and conditions. The comparative results are discussed and showed the effectiveness of the new Algoraphilic navigation algorithm.

  • Description: This book examines the nuanced and situated experiences of self-study researchers. It explores the ways in which ethics are dynamic, idiosyncratic and require an ongoing ethical reflexivity. In addition, the book identifies, documents and collates the collective experiences of self-study researchers and sheds new light on the role and impact of ethics, ethical dilemmas and ensuing decisions for education researchers. The book considers the ethical dilemmas that self-study researchers in teacher education face, their careful ethical considerations while conducting research, and how they form their professional judgment and understanding of what it means to be an ethical self-study researcher. For self-study researchers, there are a number of ethical dilemmas and challenges that cannot be neatly captured by the frameworks and guidelines of an ethics board. For many, this requires researchers to be ever-present and re-engaged with the ethics of their own projects, from the development, through to the dissemination of their work. Readers will gain a deeper understanding of ethics, ethical perspectives and practices in the field of self-study research.

  • Description: Globally, sustainability is a complex and contested term with multiple meanings and interpretations. This chapter highlights research that was undertaken by a FUGuE (Federation University Australia Gippsland) academic who used a participatory arts-based methodology to frame research with Gippsland children involved in sustainability education. The study originated from the author's involvement in the Regional Centre of Expertise in Education for Sustainable Development (known as RCE Gippsland), a global network of formal, non-formal and informal education organisations responsible for the mobilisation of education for sustainable development (ESD). Drawing on RCE Gippsland's inaugural Sustainable Schools Expo, an event that supports primary school students to engage in sustainability themes and workshops and share their respective education for sustainability initiatives, the study involved working with children who were keynote Expo speakers. A key innovation of the study was the use of sustainability artefacts created by children, which represented their sustainability learning and knowledge and were used in recorded dialogical conversations. Findings from the study highlight regional children's well-developed views about the state of the world, including their concern for humankind's impact on planetary sustainability and the subsequent decline of ecological systems locally and globally. Further to this, the immersion of regional children in places where they lived and learnt was highlighted as integral to their sustainability knowledge and understanding. The chapter concludes with a discussion about the methodological contributions of the study and its capacity to illustrate the voice of regional children and their place-oriented lifeworlds. © Springer Nature Singapore Pte Ltd. 2019.

Partnership stakeholders in this particular study included the two authors (Hongming and Monica-Federation University Gippsland Education (FUGuE) researchers and science teacher educators), pre-service teachers and teachers/students from a local primary school. The chapter explores a number of complexities pertaining to our redesign of a science education course in the Bachelor of Education (primary) teaching programme. Central to the changes we made was a transition from universitybased lectures to place-based science lessons conducted by pre-service teachers in a local wetland. As part of the self-study, we met regularly throughout the semesterlong science education course to discuss course preparation, implementation, design and delivery. These recorded and later transcribed conversations became the main data collection source of the study.We also generated personal autobiographies as a way of reflecting on our personal, professional and collective learning journey within the science education course.Our analysis of this overall process brings to light emergent levels of complexity and uncertainty in our attempt to reshape science education through a partnership model. While we each had and shared very different experiences of the science education course, the chapter pays attention to the strengths of our differences, and in particular, its contribution to our collaboration. The impact and implications of the self-study are discussed, and in conclusion, we highlight the contributions of place-oriented approaches and collegiality that supported us to undertake science differently. © Springer Nature Singapore Pte Ltd. 2019.

  • Description: Positive displacement machines have acquired particular popularity with the current push for sustainable energy production and consumption. It is currently not acceptable to waste energy available in high-pressure gasses throttled or vented to atmosphere in industrial processes (Samuel, 2007; Shu, Yu, Tian, Wei, & Liang, 2014) or blown out of cylinders in large diesel engines (Amann, 1987; Panesar, 2015; Karvountzis-Kontakiotis, Pesiridis, Zhao, Alshammari, et al., 2017). For such applications, a suitably sized positive displacement machine would be employed to harvest energy from these gases and transform it into useful forms. Turbines that are traditionally employed in massive power plants cannot be used for energy harvesting applications due to their inability to handle neither two-phase vapors (Groniewsky, Gy€orke, & Imre, 2017) nor flow occurring at small rates. For these applications, a gas expander, which is a positive displacement machine is usually employed. In relation to pressure creation, positive displacement pumps and compressors are commonly employed to impart pressure to respectively gaseous and liquid fluids flowing at rates which are required by most industries. This chapter presents the limac¸on rotary positive displacement machine, which can be employed for energy production (i.e., as a gas expander) and energy consumption (i.e., as a compressor or a pump) with equal ease and effectiveness. The limac¸on machine (Sultan, 2005) offers a straightforward technology, which has occurred to many creative minds as evident by patents which can be traced back to the 19th century. However, it is unfortunate that such technology did not make it to mass production due to the lack of mathematical understanding of their geometric characteristics and unavailability of manufacturing tools required to machine their chambers. Recently, however, with technical papers published on the topic, industry take-up of the technology has started to emerge. A good example of this take up is shown by the patent of Nystrom (2016).

  • Description: The history of Ballarat, situated at the heart of the goldfields of central Victoria, Australia, is closely tied to the colonial experience. As the site of the Eureka Stockade rebellion, its history is linked to the foundation myths of Australian democracy. It boasts both the Museum of Australian Democracy at Eureka (M.A.D.E), situated on one of the suspected sites of the rebels' stockade, and Australia's premier open air museum, the theme park of Sovereign Hill, which re-enacts life on the goldfields of the 1950s and 1860s. In Ballarat itself many of the businesses utilise symbols of the goldfields in their advertising and trademarks, as do many of the street names, festivals and public events. The Victorian architectural heritage is highly prized and showcased to the thousands of visiting tourists on Sturt and Lydiard Streets, and particularly those who come each year for Ballarat's Heritage Weekend festival held in May. Yet there is a dark side to this history. The prosperity of the gold was built on the land of the Wathawurrung Aborigines who were displaced and marginalised, and suffered under the weight of colonial occupation and environmental devastation. Likewise, despite the prominence of stories surrounding those who became wealty on the goldfields of central Victoria, many who came to Ballarat during the Victorian era found themselves displaced and living in extremen poverty, facing disease, hunger and vulnerability to crime, prostitution and dangerous working conditions. It is these stories from the underbelly of Ballarat's heritage that form the fodder of a thriving dark tourist industry, expressed in popular ghost tours and supplemented by a rich heritage of ghost stories in folklore and popular culture. In the tension between these two discordant narratives Ballarat has become, in popular imagination, a haunted city.

  • Description: This chapter is intended to show that it is possible to obtain a considerable improvement in compressor performance and reliability by modifying the design of the compressor drive. Instead of the traditional slider-crank mechanism, which has been used as a drive since the compressor industry started, it is now possible to replace this drive by more sophisticated ones which offer more flexible stroke design. Such replacement has been made possible by the modern manufacturing methods and analysis tools which are currently at the disposal of industry and research bodies. Earlier work in the domain of proposing new linkages to drive positive displacement machines can be found in the work by Ooi and Wan (2000) who presented a proposal to drive the compressor piston directly from the back using a camlike mechanism. Also, Mimmi and Pennacchi (2001) proposed a pump drive that produces four variable-length strokes per crank revolution. On the other hand, Sultan and Kalim (2011) presented a five-bar geared linkage which can be used to drive a reciprocating compressor instead of the conventional slider-crank mechanism. The next section will present a mathematical model for the compressor operation.
