- Description: This study of Northern Territory charophytes documents 22 species in 3 of the genera in tribe Chareae, family Characeae, including 15 previously described species (Chara benthamii, C. erythrogyna, C. globularis, C. karolii, C. lucida, C. porteri, C. protocharoides, C. setosa, C. submollusca, C. wightii, C. zeylanica, Lamprothamnium capitatum, L. compactum, L. stipitatum, Lychnothamnus barbatus) of which 2 are new for the Australian flora (C. erythrogyna and C. wightii), as well as 5 varieties raised to species rank (C. aridicola, C. arnhemensis, C. bancroftii, C. behriana, C. duriuscula), and 2 newly described species (C. lamprothamniformis, C. schultae). Three previously reported species in the tribe (C. braunii, C. corallina, C. fibrosa) are not recorded from the Northern Territory in this study, as previous records were based on erroneous identifications or localities. Although Northern Territory specimens of Lychnothamnus barbatus have not been seen, it has been included in this treatment, because it occurs in south-eastern Queensland, the Gulf of Carpentaria, Papua New Guinea and Timor-Leste. A key, illustrations and descriptions of all the species are provided.

- Description: The purpose of this study is to explore the impact of the PESTLE (Political, Economic, Social, Technological, Legal, and Environmental) framework on the motivations of Chinese students to pursue a higher education degree at Australian universities following the COVID-19 pandemic. We conduct a survey with a unique sample of 446 Chinese undergraduate students who are looking to study a postgraduate degree abroad. Seldom used in an educational setting, our empirical findings show a positive effect of PESTLE, particularly the economic factor, on students’ choice to study abroad, which is contrary to the null hypothesis. This study has broader implications for university administrators as it suggests that the PESTLE model can be a useful tool in analyzing education choices at a time of uncertainty. © 2023 The Authors

- Description: Objective: There remains a lack of consensus around nosology for compulsive exercise (CE). Although widely observed in eating disorders (ED), CE shares theoretical overlap with obsessive-compulsive disorder (OCD), where exercise compulsions occur in response to obsessions. Yet, there is limited and mixed evidence of a relationship between CE with OCD. This study aims to explore the appropriate diagnostic classification of CE through examination of CE in relation to OCD, obsessional thinking, and ED symptoms. Method: Two hundred and eighty one adults with mental health symptoms, dieting, and exercise behaviour completed measures of OCD, CE, and disordered eating symptoms. Regression and Receiver Operating Characteristic analyses examined relationships between dimensions of CE with OCD and ED symptoms, and the predictive ability of CE assessment for detecting threshold OCD and ED symptoms. Results: CE assessment was poor at predicting threshold OCD symptoms, probable Anorexia Nervosa, and Binge Eating Disorder and moderate at detecting probable disordered eating and Bulimia Nervosa. Associations between CE and OCD symptoms were not significant after adjustment for ED symptoms. Obsessional thinking was associated only with lack of exercise enjoyment. Conclusions: Results indicate that excessive exercise might represent a distinct disorder, with some shared traits across CE, OCD and ED symptoms. Findings question the utility of adaptation of OCD diagnostic criteria for CE. Assessment and treatment implications are considered. © 2023 The Authors.

- Description: Tropical cyclones (TCs) as a natural hazard pose a major threat and risk to the human population globally. This threat is expected to increase in a warming climate as the frequency of severe TCs is expected to increase. In this study, the influence of different monthly sea surface temperature (SST) patterns on the locations and frequency of tropical cyclone genesis (TCG) in the Southwest Pacific (SWP) region is investigated. Using principal component analysis and k-means clustering of monthly SST between 1970 and 2019, nine statistically different SST patterns are identified. Our findings show that the more prominent ENSO patterns such as the Modoki El Niño (i.e., Modoki I and Modoki II) and Eastern Pacific (EP) El Niño impact the frequency and location of TCG significantly. Our results enhance the overall understanding of the TCG variability and the relationship between TCG and SST configurations in the SWP region. The results of this study may support early warning system in SWP by improving seasonal outlooks and quantification of the level of TC-related risks for the vulnerable Pacific Island communities. © 2022, The Author(s).

- Description: Remote coaching via the use of digital technologies has been utilized within Paralympic Sports since 2015 to address challenges experienced by coaches. These technologies have connected coaches and athletes in real time, alleviating time and travel costs. However, very little is known about the experience of coaching in these environments. Therefore, the aim of this study was to explore the experiences of coaches’ use of remote coaching technologies. Seven coaches from five Paralympic Sports were recruited for this study and participated in semistructured interviews. Additionally, observations were conducted of remote coaching sessions that were part of their regular training schedules. Coaches’ insights highlight that remote technologies created opportunities to increase coach–athlete interactions and positively impact the development of interpersonal relationships. This allowed coaches to explore and exploit newly discovered information from within training environments to aid athletes in skill development. Additionally, remote coaching provided unexpected opportunities for coach development. However, coaches also reported new environmental and logistical challenges which disrupted their usual coaching approach. Overall, remote coaching technologies were perceived as being beneficial despite the challenges experienced. However, future research that looks to understand how to impact coach and athlete development through the online environment is encouraged. © 2023 Human Kinetics, Inc.

One question that arises, is how esports athletes develop the necessary skills required to improve and compete. This perspective piece opens the door to skill acquisition within esports and how research through an ecological approach can benefit researchers and practitioners as they understand the various perception-action couplings and decision-making challenges faced by esports athletes. We will identify and discuss what constraints look like in esports, the role of affordances, and theorize the implementation of a constraints-led approach in contrasting esports genres. As esports is technology-heavy in nature and generally sedentary, the use of eye-tracking technology is argued to represent an effective method to better understand perceptual attunement between individuals and teams. Future research into skill acquisition in esports is needed to develop a clearer picture of what makes the greatest esports player so great, and how newer players can be developed effectively.

- Description: Estimating various properties of soil, including moisture, carbon, and nitrogen, is crucial for studying their correlation with plant health and food production. However, conventional methods such as oven-drying and chemical analysis are laborious, expensive, and only feasible for a limited land area. With the advent of remote sensing technologies like multi/hyperspectral imaging, it is now possible to predict soil properties non-invasive and cost-effectively for a large expanse of bare land. Recent research shows the possibility of predicting those soil contents from a wide range of hyperspectral data using good prediction algorithms. However, these kinds of hyperspectral sensors are expensive and not widely available. Therefore, this paper investigates different machine and deep learning techniques to predict soil nutrient properties using only the red (R), green (G), and blue (B) bands data to propose a suitable machine/deep learning model that can be used as a rapid soil test. Another objective of this research is to observe and compare the prediction accuracy in three cases i. hyperspectral band ii. full spectrum of the visual band, and iii. three-channel of RGB band and provide a guideline to the user on which spectrum information they should use to predict those soil properties. The outcome of this research helps to develop a mobile application that is easy to use for a quick soil test. This research also explores learning-based algorithms with significant feature combinations and their performance comparisons in predicting soil properties from visual band data. For this, we also explore the impact of dimensional reduction (i.e., principal component analysis) and transformations (i.e., empirical mode decomposition) of features. The results show that the proposed model can comparably predict the soil contents from the three-channel RGB data.

- Description: The uniaxial compressive strength (UCS) of rocks is one of the key parameters for evaluating the safety and stability of civil and mining structures. In this study, 386 rock samples containing four properties named the load strength (PLS), the porosity (Pn), the P-wave velocity (Vp), and the Schmidt hardness rebound number (SHR) are utilized to predict the UCS using several typical empirical equations (EA) and artificial intelligence (AI) methods, i.e., 16 single regression (SR) equations, 2 multiple regression (MR) equations, and the random forest (RF) models optimized by grey wolf optimization (GWO), moth flame optimization (MFO), lion swarm optimization (LSO), and sparrow search algorithm (SSA). The root mean square error (RMSE), determination coefficient (R2), Willmott’s index (WI), and variance accounted for (VAF) are used to evaluate the predictive performance of all developed models. The evaluation results show that the overall performance of AI models is superior to empirical approaches, especially the LSO-RF model. In addition, the most important input variable is the Pn for predicting the UCS. Therefore, AI techniques are considered as more efficient and accurate approaches to replace the empirical equations for predicting the UCS of these collected rock samples, which provides a reliable and effective idea to predict the rock UCS in the filed site. © 2023 by the authors.

The data was extracted and analysed via descriptive and inferential statistics and compared to a specialised mental health team, experienced with the ZS approach. Results: A total of 334 clinical records were extracted for January, April, August, November 2019 and June 2020. The clinical audit and analysis confirmed that the mental health teams are not consistently using the assessments from their training and are therefore not implementing all of these elements into their practice. This could have implications for the risk formulation and treatment for people at risk of suicide. Conclusions: The use of a validated clinical audit tool can be beneficial to establish compliance with the mental health clinicians and to determine any areas requiring further improvement. Further education and reinforcement may be required to ensure consistency with incorporating the elements of ZS into everyday clinical practice. © 2022 by the authors.

- Description: Objectives: Better understanding of compulsive exercise is needed in sports medicine. Whilst compulsive exercise may impact mental health, the limited research exploring the relationship between compulsive exercise and psychosocial outcomes is equivocal. The majority of studies have examined eating disorder populations where the eating disorder pathology might account for distress. This study explores relationships between compulsive exercise and mental health. Design: Cross-sectional observational study. Methods: Australian recreational exercisers and athletes (N = 1157; Mage 36.4, standard deviation = 12.9, 77 % female) recruited through sporting organisations, clubs, and gyms, completed measures of compulsive exercise, depression, anxiety, stress, life satisfaction, social physique anxiety, and self-esteem. Regression analyses examined relationships between dimensions of compulsive exercise and wellbeing. Results: After adjustment for eating disorder symptoms and sporting level, compulsive exercise was associated with increased risk of clinically-significant anxiety, depression, and stress symptoms. Compulsive exercise was also associated with lower life satisfaction and self-esteem, and higher social physique anxiety. Notably, different dimensions of compulsive exercise had varying relationships with outcomes, and avoidance and rule-driven behaviour and lack of exercise enjoyment were associated with poorer mental health and wellbeing. Conclusions: Results suggest that compulsive exercise is uniquely associated with a range of psychosocial and mental health outcomes. Results support the need to improve identification and treatment of compulsive exercise in sport and exercise settings. Results highlight that mental health intervention is an important component of treatment, and treatments targeting symptoms related to avoidance and rule-driven behaviour, and anhedonia may be valuable treatment components for those with compulsive exercise. © 2023 The Author(s)

- Description: Objectives: To explore Australian cricket participants' knowledge of concussion assessment and management, and awareness of current concussion guidelines. Design: Cross-sectional survey. Methods: Novel and validated surveys were disseminated online, among over 16 year Australian cricket players and officials at the end of the 2018/19 cricket season. Data were collected on knowledge and awareness of concussion and analysed using descriptive statistics and crosstabulations. Further comparisons were made for the players between injured and non-injured, and helmet wearers and non-helmet wearers using Fisher's exact statistical test. Results: Both players (n = 224, 93 %) and officials (n = 36, 100 %) demonstrated strong knowledge of the importance of immediately evaluating suspected concussions. In comparison with players without helmets (n = 11), those using helmets (n = 135) considered replacing their helmets after a concussion to be vital to concussion assessment (p = 0.02). Overall, 80–97 % of players and 81–97 % of officials understood the importance of many factors regarding concussion management. When concussion management knowledge was compared by injury status, injured players (n = 17, 94 %) believed someone with a concussion should be hospitalised immediately, in contrast to non-injured players (n = 154, 69 %) (p = 0.04). Players (63 %) were less aware of concussion guidelines than officials (81 %). Conclusions: Overall, the knowledge of concussion assessment and management was satisfactory. However, there were discrepancies among players on some aspects of awareness of concussion guidelines. Increasing players' familiarity and experience in using the concussion guidelines is warranted. Targeted campaigns are needed to further improve concussion recognition and treatment at community-level cricket, so all participants play a role in making cricket a safe sport. © 2023

- Description: A general technique to develop arbitrary-sided polygonal elements based on the scaled boundary finite element method is presented. Shape functions are derived from the solution of the Poisson's equation in contrast to the well-known Laplace shape functions that are only linearly complete. The application of the Poisson shape functions can be complete up to any specific order. The shape functions retain the advantage of the scaled boundary finite element method allowing direct formulation on polygons with arbitrary number of sides and quadtree meshes. The resulting formulation is similar to the finite element method where each field variable is interpolated by the same set of shape functions in parametric space and differs only in the integration of the stiffness and mass matrices. Well-established finite element procedures can be applied with the developed shape functions, to solve a variety of engineering problems including, for example, coupled field problems, phase field fracture, and addressing volumetric locking in the near-incompressibility limit by adopting a mixed formulation. Application of the formulation is demonstrated in several engineering problems. Optimal convergence rates are observed. © 2023 The Authors.

Contrasting colonial collectors: an examination of nineteenth-century collectors of Victorian Indigenous cultural artefacts, violence and antiquarianism
- Authors: Donovan, Paul
- Date: 2023
- Type: Text , Thesis , PhD

- Description: The motivations and methodologies for collecting Indigenous Australian cultural material from colonial Victoria from 1802–1900 have varied widely. Some collectors enacted frontier war to disarm a colonised people and dispossess them of their land. Others sought to salvage a material scientific record of the culture of a race they believed was doomed to imminent extinction or build museum collections for public education. Some sought souvenirs or gifts to document tourism experiences, and some acquired exotic material for commercial enterprise. This dissertation offers a historical overview of political and scientific paradigms underpinning the collection of Indigenous Australian cultural material from nineteenth-century Victoria and characterises the resulting collecting practices. The nature of the collection methods and the content of the collections were examined. The dynamics of relationships between nineteenth-century collectors, Indigenous Australian communities, the source of collections, and collecting institutions were analysed following on from Nicholas Thomas’s entangled objects framework and using the methodologies of Geertz’s thick description, McBryde’s ethnohistory, Denzin’s interpretive biography and Thomas, Znaniecki and Shaw’s biographical analysis. By examining evidence in the primary sources of Indigenous Australian value for colonial material and colonial value of Indigenous material, this dissertation deconstructed the nature of the relationships between agents. It explored the nexus between objects, institutions and individuals. The case studies add depth to the understanding of the collections of Victorian cultural material still held in museums.

- Description: This study introduces a practical energy conversion (EC)-type modeling framework capable of converting the optimum compaction properties of fine-grained soils between any two rational compaction energy levels (CELs). Model development/calibration was carried out using a database of 242 compaction test results — the largest and most diverse database of its kind, to date, entailing 76 fine-grained soils (covering liquid limits of 16–256%), with each soil tested for at least three different CELs. On establishing the framework, an independent database of 91 compaction test results (consisting of 34 fine-grained soils tested for varying CELs) was employed for its validation. The proposed EC-based models employ measured optimum water content (OWC) and maximum dry unit weight (MDUW) values obtained for a rational CEL (preferably standard Proctor) to predict the same for higher and/or lower compactive efforts (covering 214–5416 kJ/m3).

- Description: Background: The COVID-19 pandemic has detrimental effects on both physical and psychological well-being of community people worldwide. The purpose of this research was to determine coping strategies and the factors associated with psychological distress and fear among adults in Kuwait during the COVID-19 pandemic. Results: Participants with good-excellent mental health perception had significantly lower prevalence of reporting high psychological distress, while those identified as patients as used health services in the past 4 weeks had significantly higher prevalence of reporting high psychological distress. On the other hand, individuals born in the same country of residence, whose financial situation was impacted by COVID-19 had significantly lower prevalence of reporting high levels of fear from COVID-19. Those with an income source, with co-morbidities, tested negative to COVID-19, being frontline or essential worker, reported medium to high psychological distress and had significantly higher prevalence of high levels of fear of COVID-19. Conclusions: Mental health services should be provided in addition to the existing services in primary healthcare settings, so that the impact of ongoing pandemic on psychological wellbeing of people in Kuwait can be addressed. © 2023, The Author(s).
