- Description: In the design of positive displacement compressors, the mathematical relationship between design parameters and design objectives is usually impractical and costly to be extracted, making the optimization process becomes a 'black-box' problem. In the available literature, the Bayesian optimization method, compared to other optimization techniques, has been proven as an accurate and efficient method to solve the 'black-box' problem. However, the application of such a method in the design of the rotary compressor has not been discussed in published papers. Hence, the current study is intended to employ Bayesian optimization to geometric design a class of positive displacement compressors, which is known as the limaçon compressor. In this paper, the geometric characteristics of the limaçon compressor are presented, and a function, which incorporates volumetric and geometric aspects, is employed to evaluate the optimization process and to reveal the optimum design scenario as per design requirements. A case study is offered to prove the validity of the presented approach. © 2022 American Institute of Physics Inc.. All rights reserved.

- Description: In this paper, a class of rotary positive displacement compressors which is known as the limaçon compressor is introduced. The main feature of such a compressor is that profiles of its housing and rotor and the motion of its rotor are developed from a mathematical curve called the limaçon of Pascal. A mathematical model of the limaçon compressor, which incorporates the mass flow of the working fluid, the leakage loss, the dynamic response of the discharge valve, as well as the thermodynamic behaviors, is formulated, and the simulation of such a model has been performed to study the operational characteristics of the limaçon compressor. A parametric analysis is also conducted to investigate the effects of various parameters on the compressor performance. Based on the results, it is found that the machine performance deteriorates as the operating speed increases despite an initial rise in the volumetric efficiency. Additionally, the isentropic efficiency appears insensitive to the change of the pressure ratio, whereas a negative effect on the volumetric efficiency is noticed when the pressure ratio is increased. The effect of the valve diameter on the over-compression loss has also been studied, and the result indicates that a smaller valve diameter leads to a higher level of fluid over-compression. © 2021 Elsevier Ltd and IIR

- Description: Reciprocating compressors have found popularity in applications where compressed air is required at high pressure levels with moderate flow rates. The mechanical drives used for these compressors are based on the traditional slider-crank linkage which, despite its simplicity, does not lend itself to optimization effort aimed at improving the compressor reliability and performance. The work presented in this paper adopts the notion that the mechanical reliability of the compressor drive is limited by the level and cyclical variability of the loads transmitted through its members and the effectiveness of its cooling system. In the paper, machine learning methods will be employed to craft an objective function suitable to use in a Bayesian optimization effort undertaken to produce a more reliable compressor drive. A numerical example is presented to prove the validity of the presented method and its suitability for use in real life compressor designs. © 2021 IEEE.

- Description: This paper investigates the initial state of excavated soil and rock (ESR). These initial states include dry density, organic content, water content (Wc), cement content (Cc), liquid index (LI), dry or wet mixing method. Three ESRs collected from tunnelling projects and kaolin were used in this study to compare. The specimens (i.e., 50 mm in diameter and 100 mm in height) were prepared in the laboratory and cured at 7 and 14 days, and then assessed by the unconfined compressive strength (UCS) test. The analysis shows that the ratio of Wc/Cc is the primary factor to obtain different UCS for high LI ESR and a simple equation is proposed for quick prediction. For ESR with a more general LI, predictive equations are also proposed in terms of artificial neural network (ANN) and genetic programming (GP) for 7-days curing time. The results indicate that the both ANN models with Bayesian Regularization (BR) algorithm outperform ANN with Levenberg-Marquardt (LM) and GP model are accurate to predict UCS of mixtures. © 2023 Elsevier Ltd

- Description: The aim of this study is to examine the factor structure of the scale of Job Satisfaction Survey (JSS), and its divergent and convergent validity in Chinese population. Data were collected with JSS from 1073 urban employees in Liaoning. Four alternative models were tested with confirmatory factor analysis. The first two models are models validated in the US, while the third and fourth models are composed of five commonly used dimensions of job satisfaction taken from JSS. The research found a poor model fit for the first two models, suggesting a possible national difference between China and the US. However, model three and model four displayed a good model fit, suggesting that the five dimensions in JSS (satisfaction with nature of work, with supervision, with co-worker, with promotion, and with pay) are five distinct dimensions. The correlations between these five facet job satisfaction and PA and NA demonstrated convergent and divergent validity of the scales for these five dimensions of job satisfaction.

- Description: New wave therapies such as Acceptance and Commitment Therapy aim to cultivate people's psychological flexibility in order for them to live a satisfying life. Psychological flexibility has also a role in promoting mental health, which may mediate the relationship with life satisfaction. The aim of this study was to determine whether mental health mediates the effect of psychological flexibility on life satisfaction. A convenience sample of 140 adults (32 males, M = 36.50 years, SD = 12.22; 107 females, M = 38.46 years, SD = 12.81; and a 45-year-old person of unknown gender) completed an online questionnaire assessing psychological flexibility, mental health and life satisfaction. Three of the four hypothesized components of psychological flexibility (experiential acceptance, cognitive alternatives and cognitive control) contributed to the latent construct of psychological flexibility, but cognitive defusion failed to contribute. Psychological flexibility had a direct, positive effect on life satisfaction and the hypothesis that mental health would mediate this relationship was supported. The results suggest that psychological flexibility is important for one's mental health and that both are integral to life satisfaction. The results also support a continued focus on third-wave therapies in cultivating psychological flexibility. © The Author(s) 2019. Published by Oxford University Press. All rights reserved.

Reflective leadership : A self-study of practice

- Description: Encouraging reflective leadership practice is a recognised focus for coaches and consultants in primary schools. Despite the wealth of knowledge on coaching and consulting in organisational learning, there is less known about the transition between these two interactions and the purpose behind this. This self-study of my practice as a regional school improvement officer in Victoria, Australia, details my interaction with six teacher-leaders, who considered school improvement strategies by constructing a pattern-block representation of the structures within their schools. The research questions posed were: “What do teacher-leaders reflect upon when considering school improvement approaches?” and “How does the external facilitator encourage teacherleaders to reflect upon their practice?” Research undertaken for this study was used to develop a range of statements related to Donald Schön’s theory of reflective practice, particularly reflection-in-action. The statements were presented as a stimulus for action in practice and encompassed a range of tensions. Tensions included; orchestrating change by moving between the current situation and a preferred future; making connections by acknowledging the complexity of the situation whilst attempting to create order; developing a strategy from the consideration of a shared vision and a written plan; and undertaking leadership by moving between hierarchical, distributive and self-organising structures. Tacit and explicit knowledge was evident when reflecting-inaction. Finally I explored how, as the external facilitator, I encouraged reflection by moving between coaching and consulting interactions. I began this research by examining the practice of others. However, the greatest learning I achieved related to how I reflected-in-action and my understanding of self-study in practice. Initially in this study, I placed myself at the centre of the research and considered this a selfin- study; however, as the study progressed, I examined both my practice and the research simultaneously, terming this self-and-study, and, finally, from my analysis of the research when the study concluded, I developed a series of statements that could be used as a stimulus for future action, which I refer to as self-from-study. The larger implication for this research therefore relates to my understanding of my own reflection-in-action and how by embracing a number of tensions one can consider a range of possibilities for improvement.

- Description: Objective: To identify gaps among Australian Long COVID support services and guidelines alongside recommendations for future health programs. Methods: Electronic databases and seven government health websites were searched for Long COVID-specific programs or clinics available in Australia as well as international and Australian management guidelines. Results: Five Long COVID specific guidelines and sixteen Australian services were reviewed. The majority of Australian services provided multidisciplinary rehabilitation programs with service models generally consistent with international and national guidelines. Most services included physiotherapists and psychologists. While early investigation at week 4 after contraction of COVID-19 is recommended by the Australian, UK and US guidelines, this was not consistently implemented. Conclusion: Besides Long COVID clinics, future solutions should focus on early identification that can be delivered by General Practitioners and all credentialed allied health professions. Study findings highlight an urgent need for innovative care models that address individual patient needs at an affordable cost. We propose a model that focuses on patient-led self-care with further enhancement via multi-disciplinary care tools.

Internationalisation of higher education curriculum : a case study in Vietnam
- Authors: Luong, Thi Phuong
- Date: 2020
- Type: Text , Thesis , PhD
- Full Text:
- Description: This thesis investigated how the process of internationalisation of the curriculum (IoC) was perceived as taking place at a non-western university, namely Foreign Trade University (FTU) in Vietnam, through the development and offering of a number of jointly run programs, labelled Foreign Undergraduate Programs (FUPs). Two specific programs were examined, both of which were developed in partnership with two western universities – Colorado State University (FTU-CSU program) and London Metropolitan University (FTU-LMET program). These programs provide a range of opportunities for Vietnamese university students to experience an education that aims to reflect an international and therefore ‘broader’ context. The relationship between globalisation and internationalisation is explored and linked with the development of curriculum in higher education and internationalisation trends and strategies. Internationalisation of the curriculum, which is one of the internationalisation strategies employed by educational institutions, is investigated in terms of its interrelationship with student learning, the disciplines and academics. Engeström’s (2001) third generation Activity Theory was used as the theoretical lens for analysis of the data, which was collected via a mainly qualitative case study. Two cohorts of participants provided data through 24 interviews (seven including a joint one with program leaders/course coordinators, and 17 with academics) and 34 surveys completed by academics. The interviews/survey investigated participants’ perceptions about internationalisation and particularly IoC in relation to the two programs. Part of the significance of this study lies in the use of a number of conceptual and theoretical frameworks to extend the current body of literature beyond the main context of western higher education. An innovation in this study was the evaluation of the level of curriculum internationalisation at FTU, which was conducted using the model of curriculum internationalisation proposed by Huang (2017). Findings suggested that program managers and course coordinators worked collaboratively with their western partners to provide programs that they perceived as worthwhile in meeting the needs of the institution and the Vietnamese government agenda for internationalisation. However, academics were not generally well informed about the broader goals relating to IoC and found it challenging to accommodate the expectations with limited resources and lack of appropriate training.

- Description: Adherence to antiplatelet therapy is critical to successful treatment of cardiovascular conditions. However, little has been known about this issue in the context of constrained resources such as in Vietnam. The objective of this study was to examine the adherence to antiplatelet therapy among patients receiving acute myocardial infarction interventions and its associated factors. In a cross-sectional survey design, 175 adult patients revisiting Vietnam National Heart Institute diagnosed with acute myocardial infarction were approached for data collection from October 2014 to June 2015. Adherence to antiplatelet therapy was assessed by asking patients whether they took taking antiplatelet regularly as per medication (do not miss any dose at the specified time) for any type of antiplatelet (aspirin, clopidogrel, ticlopidine.) during the last month before the participants came back to take re-examinations. The results indicated that the adherence to antiplatelet therapy among patients was quite high at 1 month; it begins to decline by 6 months, 12 months, and more than 12 months (less than 1 month was 90.29%; from 1 to 6 months 88.0%, from 6 to 12 months 75.43%, and after 12 months only 46.29% of patients). Multivariable logistic regression was utilized to detect factors associated with the adherence to antiplatelet therapy. It showed that patients with average income per month of $300 or more (OR=2.92, 95% CI=1.24-6.89), distance to the hospital of less than 50km (OR=2.48, 95% CI: 1.12-5.52), taking medicine under doctor's instructions (OR=3.65; 95% CI=1.13-11.70), and timely re-examination (OR=3.99, 95% CI=1.08-14.73) were more likely to follow the therapy. In general, the study suggested that to increase the likelihood of adherence to antiplatelet therapy it is important to establish a continuous care system after discharging from hospital. © 2019 Ngoc Minh Luu et al.

- Description: Adherence to antiplatelet therapy is critical to successful treatment of cardiovascular conditions. However, little has been known about this issue in the context of constrained resources such as in Vietnam. The objective of this study was to examine the adherence to antiplatelet therapy among patients receiving acute myocardial infarction interventions and its associated factors. In a cross-sectional survey design, 175 adult patients revisiting Vietnam National Heart Institute diagnosed with acute myocardial infarction were approached for data collection from October 2014 to June 2015. Adherence to antiplatelet therapy was assessed by asking patients whether they took taking antiplatelet regularly as per medication (do not miss any dose at the specified time) for any type of antiplatelet (aspirin, clopidogrel, ticlopidine.) during the last month before the participants came back to take re-examinations. The results indicated that the adherence to antiplatelet therapy among patients was quite high at 1 month; it begins to decline by 6 months, 12 months, and more than 12 months (less than 1 month was 90.29%; from 1 to 6 months 88.0%, from 6 to 12 months 75.43%, and after 12 months only 46.29% of patients). Multivariable logistic regression was utilized to detect factors associated with the adherence to antiplatelet therapy. It showed that patients with average income per month of $300 or more (OR=2.92, 95% CI=1.24-6.89), distance to the hospital of less than 50km (OR=2.48, 95% CI: 1.12-5.52), taking medicine under doctor's instructions (OR=3.65; 95% CI=1.13-11.70), and timely re-examination (OR=3.99, 95% CI=1.08-14.73) were more likely to follow the therapy.

The inimitable Mr Meek : Re-discovering a lost art

- Full Text:
- Description: James McKain Meek was a Victorian-era graphic artist, miniature calligrapher and colonial eccentric with polymathic interests, who fell into obscurity at the end of the nineteenth century. This research re-discovers, re-presents and re-evaluates his body of graphic art. A single lithograph by Meek held in the Art Gallery of Ballarat’s collection generated the research which uncovered a significant body of work in Australia and overseas. Inspired by this re-discovered oeuvre, an exhibition was curated to mark Meek’s bicentenary, returning him to public view. An illustrated companion catalogue, the first scholarly commentary on Meek’s oeuvre, presented a series of essays exploring Meek’s works and situating them in their Victorian context and within a longer tradition of prints. The exegesis, the final element of this project, reflects on the research design, addresses curatorial and related issues, and deepens the examination of Meek’s output. An analysis of key works informed by Word and Image Studies explores his trademark verbal and visual interplay. Valuable research outcomes discussed include the ongoing conservation of works, contextualisation of material held in collections around the world, Meek’s place in the larger narrative of Australian art history, and his legacy. This tri-partite PhD thesis is comprised of exhibition, catalogue and exegesis: these components are complementary and designed to be considered together. The catalogue addresses an educated lay readership and the exegesis is an overarching academic commentary. The exegesis extends and references the catalogue, and both are grounded in Meek’s works, in particular, key works displayed in the exhibition. This research contends that Meek’s work is singular and argues for his re-instatement in the Australian graphic arts canon. His highly individual style and the fact he is local (in his special links with Ballarat and his Trans-Tasman career), make him of particular interest in the Victorian and Australasian contexts.

- Description: Offshore islands are often important in conservation because of the presence of locally endemic species and for acting as refuges for native wildlife from the impacts of invasive species and inappropriate development. Barrow Island, a small, semi-arid island off the Pilbara coast of northwestern Australia, has maintained the integrity of its terrestrial and aquatic biota despite sporadic incursions by invasive species and the operation of commercial oil extraction and liquified natural gas processing for over 50 years. We collate information from a wide range of sources to provide a framework to inform the ongoing management of the terrestrial and aquatic fauna and flora species that have conservation significance on the island. These include endemic flora and fauna; species listed as threatened by state, national and international authorities; species that are rare or extinct in other parts of their original range; species of biogeographic significance; and migratory birds and marine fauna of national and international significance. In addition, Barrow Island has been of value in acting as a source area for translocations of vulnerable and endangered mammal species that have been eradicated in other parts of their range. The many species with conservation significance and their use in successful translocation programs demonstrates the island’s national and international importance for conservation. In addition, Barrow Island provides exemplary opportunities for research on effective co-management of development and conservation, on mitigation and prevention of the invasion and impacts of exotic species, and on the influence of historical biogeographic processes on the distributions and evolution of biota. © Royal Society of Western Australia 2019.

- Description: The attraction sector’s ability to enhance service quality is fundamentally important to its future sustainability. Attempts to enhance performance within the sector have suffered from the lack of a standard instrument for measuring service quality perceptions. This study sought to address this issue by piloting an instrument designed to measure visitor levels of perceived service quality. The instrument was piloted on 133 visitors to four purpose built attractions in Victoria, Australia. Analysis of the data resulted in a purified 17-item instrument, called ATTRACTQUAL and proposed that two dimensions, interactions and outcomes, underlie attraction visitors’ perceptions of service quality.

- Description: Teenage pregnancy is associated with adverse social, economic and health outcomes for both mother and child. The factors frequently associated with teenage pregnancy or related sexual health issues include teenagers' knowledge, attitudes, and beliefs about sex and other social-economic factors such as levels of poverty, academic success or failure, and parents' education. This paper reports on the evaluation of a teenage pregnancy program conducted in the Southern and North Western regions of Tasmania to address the high levels of teenage pregnancy and sexually transmitted infection (STIs) in these regions. The aim of the study was to examine the effectiveness of the Teenage Pregnancy Programs by examining any evidence for a community change in attitudes and behaviours, and any changes in youth awareness about sexual health. The study adopted a qualitative approach and data were collected from a total of 25 participants (17 who were interviewed and eight who participated in focus groups) residing in the target regions. Data were analysed using thematic analysis using Nvivo 9.0. The study results indicated that the program was well managed and delivered. There were reported changes in the awareness, attitudes and behaviours regarding sexual health within the target communities, which were considered necessary for young people to make well informed choices. The evaluation of the program provides valuable knowledge regarding the processes and outcomes that may have application in future community based sexual health initiatives may be delivered into regional communities.

- Description: Primary health care plays a significant role in the well-being of individuals and communities, yet access to these services can vary. Factors such as socio-economic status and location of residence can impact this access. A study was conducted to investigate the relationship between location, utilisation, quality and health outcomes of primary health care services in the Meander Valley municipality of Tasmania, Australia. This paper reports the findings of the study which adopted a mixed-methods approach with multiple sources of data including government reports, survey questionnaires and interviews. The regional socio-economic disadvantage reflected not only the health disparities and poorer health conditions, but also the affordability to seek care. This was compounded by the lower levels of available health services and private health insurance. The lack of local services or their low quality was the main motivation for many to seek care outside of the region, which was unaffordable and at times logistically impossible. On the basis of the findings, a number of recommendations are provided to guide the current and future health care services and to improve the well-being of the Meander Valley community.

- Description: There are a number of risk factors which increasingly impact the health and wellbeing of Australians, particularly in rural communities. To address the health and wellbeing of communities, local governments are taking on a more focused role by supporting healthy community initiatives (HCI). This paper presents local council partners perceptions concerning a regional-scale health promotion initiative that was undertaken in rural Tasmania, Australia. The evaluation provides insight into the future decisions and strategies that may be developed to improve processes, methods and outcomes of health initiatives undertaken by local governments. The study used a mixed methods approach collecting data through a questionnaire, focus group discussions and interviews with stakeholders and participating councils to provide an understanding of the effectiveness and success of, and barriers to, the health promotion initiative. It was found that there was an emphasis by local councils on programs that promoted physical activities, while programs that focused on healthy food and other health promotion topics, such as quit smoking and healthy workplaces were less emphasised. Overall, the health promotion initiative was perceived to be effective; however, there was little measureable evidence as to the outcomes of the various projects within the initiative and there was concern regarding the sustainability of the initiative beyond the funding timeframe. Community based, health promotion interventions are complex. Local government are suitably placed to deliver health promotion initiatives, as they have a greater understanding and can affect the greatest change by investing in projects with the highest priority among those communities within their boundaries. Nevertheless, sustainability of projects beyond funding allocation, while building and improving partnerships among local governments, and service agencies to pool resources and capture specific target groups must be central to ongoing initiatives.

- Description: Australia is considered a highly food-secure nation; however, this is not always the case for every individual, household, and community. This article examines the physical and financial access to food of the population of Dorset, a rural municipality in North East Tasmania (Australia); the impact that socio-economic factors have on their food security; and the coping strategies they use when food shortages occur. A mixed-methods approach was used: Quantitative data were collected through the Tasmanian Household Food Security Survey and qualitative data through nine community focus groups conducted throughout the Dorset municipality. A total of 364 respondents (response rate 63%) completed the survey. Two main themes were identified within the data: food availability and food access. Food availability considered food origin, sustainability, and food production, whereas food access considered physical access, financial access, and other access issues such as awareness, skills, cultural preferences, and social support. The data revealed the wide-ranging effects of the importation of cheaper food alternatives, which had long-term implications not only on individuals' health but also on the economic health of the community. A number of respondents indicated they were at times unable to buy nutritious foods due to limited finances, which led some to go without food or use other strategies to feed themselves. This study highlights the inappropriateness of the continuation of individual behavior change as a policy focus, as many of the problems facing communities are beyond individual abilities. Thus, the implications for policy from this study are centered on providing further support for strategies that focus on ensuring equity and food security for all, particularly the rural inhabitants of many food-secure nations. © The Author(s) 2015.
