- Description: Background: Continuity of Care Experiences (CoCEs) are a component of all entry-to-practice midwifery programs in Australia and facilitate an understanding of the central midwifery philosophy of woman-centred care and continuity of the therapeutic relationship. The aim of this research was to explore how CoCEs are viewed and experienced by students and academics across Australia. Methods: Students enrolled in Australian midwifery programs and academics who teach into these programs were invited to participate in a cross sectional, web-based survey. Data were analysed using descriptive statistics and free text responses were analysed using content analysis. Findings: Four hundred and five students and 61 academics responded to the survey. The CoCE was viewed as a positive and unique learning experience, preparing students to work in midwifery-led continuity models and developing confidence in their midwifery role. Challenges in recruitment, participation in care, and balancing the workload with other course requirements were evident in reports from students, but less understood by academics. Significant personal impact on finances, health and wellbeing of students were also reported. Discussion: The value of CoCEs as an experiential learning opportunity is clear, however, many students report being challenged by elements of the CoCE within current models as they try to maintain study-work-life balance. Conclusion: Innovative course structure that considers and embeds the CoCE requirements within the curricula, in addition to a collective commitment from regulatory bodies, the maternity care sector and Universities to facilitate CoCEs for students may address some of the significant student impacts that are reported by this research. © 2021 Australian College of Midwives

- Description: (1) Background: Obsessive–compulsive disorder (OCD) is a chronic mental disorder that can be a source of emotional, financial and/or social burden for family caregivers. Few studies have investigated family caregiving for patients diagnosed with OCD in relation to the coping strategies being used from a theoretical perspective. This study evaluated the burden and coping strategies of family caregivers for people diagnosed with OCD. (2) Methods: A cross-sectional study was conducted, in which 123 participants diagnosed with OCD and their caregivers were surveyed using three types of scales: obsessive–compulsive scale; coping scale; and burden scale. (3) Results: Of the participants with OCD and their caregivers, 53% and 31% were male and 47% and 69% were female, respectively. Around 80% of the OCD patients were considered young and their age ranged from 20–40 years old. Forty percent of caregivers in the current study reported a high burden level. The caregivers of those who had severe OCD symptoms had a lower coping level compared to the caregivers of those with less severe symptoms and those urban caregivers were able to better cope than rural caregivers. There was an association between OCD symptom severity and financial, work-related, social and family relationships, mental and health burdens for family caregivers. Meanwhile, the greater coping level of family caregivers, the lesser social and family, mental, and spouse relationship burden (p < 0.05); (4) Conclusions: The family caregivers of people diagnosed with OCD have specific aspects of burden and coping which require support by designing strategic interventions for family caregiver coping. © 2022 by the authors.

- Description: Since conical pick cutting is a complex process of multi-factor coupling effects, theoretical model construction for cutting force prediction is a quite difficult task. In this paper, various novel intelligent models based on chaos-optimized slime mould algorithm (COSMA) and random forest (RF) are proposed for this task. In the proposed COSMA-RF methods, the chaos algorithms with the ergodicity and randomness are introduced to chaotically determine the initial position to form a COSMA, and the SMA and COSMA are used to tune the hyperparameters of RF and mean square error are assigned as a fitness function.

- Description: This study investigated the reliability and discriminative ability of tensiomyography and countermovement jump variables as measures of a muscles contractile properties in a cohort of elite endurance and sprint track cyclists. Tensiomyography was performed on the vastus lateralis (VL) and rectus femoris (RF) muscles in sprint track cyclists (N = 8) and endurance track cyclists (N = 8). Additionally, the participants completed a countermovement jump on a force plate. Tensiomyography measurements obtained from the RF displayed greater reliability (ICC = 0.879–0.997) than VL (ICC = 0.746–0.970). Radial muscle belly displacement (Dm), contraction time (Tc) and delay time (Td) demonstrated the most reliable TMG measurements. Only two variables displayed acceptable coefficient of variation (RF Td = 8.89, VL Td = 6.88), other variables presented as unacceptable. The TMG variables were unable to discriminate between endurance and sprint track cyclists whilst the CMJ variables could. Due to the high variability in measurements and its inability to distinguish between sprint and endurance based track cyclists TMG should be used cautiously in this athlete population and if available the CMJ is a more appropriate assessment of leg muscle function. © 2022 Institute of Sport.

- Description: In building a predictive credit scoring model, feature selection is an essential pre-processing step that can improve the predictive accuracy and comprehensibility of models. In this study, we select the optimal feature subset based on group feature selection in lieu of the individual feature selection method, to establish a credit scoring model for small manufacturing enterprises. In our methodology, we first select a group of features using the 0-1 programming method, with the objective function of maximising the Gini coefficient (GINI) of the credit score to identify the possibility of default. Then we introduce constraints to remove any redundant features in the same subset, provided they reflect the same information. Finally, we assign weights to different features according to the Gini coefficient, ensuring that the weight of the features reflects their discriminatory power. Our empirical results show that the selection of a set of features more effectively identifies default status than the individual feature selection approach. Moreover, a rating system with more features does not necessarily have better discriminatory power. As the number of features exceeds the optimum number of features selected, the system's discriminatory ability begins to decrease. © Operational Research Society 2022.

- Description: Progress towards understanding how social media impacts body image hinges on the use of appropriate measurement tools and methodologies. This review provides an overview of common (qualitative, self-report survey, lab-based experiments) and emerging (momentary assessment, computational) methodological approaches to the exploration of the impact of social media on body image. The potential of these methodologies is detailed, with examples illustrating current use as well as opportunities for expansion. A key theme from our review is that each methodology has provided insights for the body image research field, yet is insufficient in isolation to fully capture the nuance and complexity of social media experiences. Thus, in consideration of gaps in methodology, we emphasise the need for big picture thinking that leverages and combines the strengths of each of these methodologies to yield a more comprehensive, nuanced, and robust picture of the positive and negative impacts of social media. © 2022 Elsevier Ltd

- Description: Microseismic location systems tend to be high-speed and precise. However, the requirement of high precision tends to slow down the calculation speed. Fortunately, metaheuristics are able to alleviate this problem. In this research, metaheuristic algorithms are used to improve the performance of cross-correlation stacking (CCS). CCS has able to provide excellent location accuracy as it uses more information in the entire waveform for location. However, this method often requires more calculation time due to its complex mathematical modeling. To overcome this problem, various metaheuristic algorithms (i.e. moth flame optimization (MFO), ant lion optimization (ALO) and grey wolf optimization (GWO)) have been used to improve CCS. It has been found that appropriate control parameters can improve the metaheuristic algorithm performance manyfold. So, these control parameters have been adjusted based on three different perspectives, i.e. success rate (SR), computational efficiency and convergence performance. The results show that these models are able to provide better location efficiency compared to the full grid search (FGS) and particle swarm optimization (PSO) based on ensuring good location accuracy. It is also found that MFO is significantly better than the other metaheuristic algorithms. In addition, the superiority of CCS over traditional location methods is verified through comprehensive tests, and the influence of the speed model and the number of sensors on the location performance of CCS was tested. © 2022 Elsevier Ltd

- Description: Purpose: The author provides an insider view of women directors' selections on corporate boards from the empirical setting of India and find if the recruitment practices in this space discriminate against women. Design/methodology/approach: The study collected data from a diverse cohort of 27 directors through semi-structured interviews. The data were analysed by applying an interpretative inductive approach and using the software NVivo's 12-plus version. Findings: The author’s findings show that board recruiters present different selection criteria and processes to women candidates depending upon heterogeneity among candidates' professional standing. Recruiters view women directors as a diverse cohort and value resourceful and experienced women when making recruitment decisions; these women directors are also found influencing directors' selection processes. Originality/value: The results question the underlying assumptions of prejudice against women as posited by the feminist and social identity theorists without accounting for the heterogeneity among women and situations. By proposing the female-gender stereotyping deactivation theory in top leadership matters, such as board selections, the author argues that stereotyping becomes irrelevant in the strategic decisions of board selections. This new theorisation about women's access to leadership roles will help the cause of women empowerment both at a cognitive and practical level. Future researchers can test the gender deactivation theory among women leaders in diverse cultural contexts by looking at the intra-cohort differences among women leaders. © 2022, Emerald Publishing Limited.

Here, using a reconstructed long-term proxy of annual TC numbers together with high-resolution climate model experiments, we show robust declining trends in the annual number of TCs at global and regional scales during the twentieth century. The Twentieth Century Reanalysis (20CR) dataset is used for reconstruction because, compared with other reanalyses, it assimilates only sea-level pressure fields rather than utilize all available observations in the troposphere, making it less sensitive to temporal inhomogeneities in the observations. It can also capture TC signatures from the pre-satellite era reasonably well. The declining trends found are consistent with the twentieth century weakening of the Hadley and Walker circulations, which make conditions for TC formation less favourable. © 2022, The Author(s).

However, little attention has been paid to scholarly data, that is, anomaly detection in a citation network. Citation is considered as one of the most crucial metrics to evaluate the impact of scientific research, which may be gamed in multiple ways. Therefore, anomaly detection in citation networks is of significant importance to identify manipulation and inflation of citations. To address this open issue, we propose a novel deep graph learning model, namely graph learning for anomaly detection (GLAD), to identify anomalies in citation networks. GLAD incorporates text semantic mining to network representation learning by adding both node attributes and link attributes via graph neural networks (GNNs). It exploits not only the relevance of citation contents, but also hidden relationships between papers. Within the GLAD framework, we propose an algorithm called Citation PUrpose (CPU) to discover the purpose of citation based on citation context. The performance of GLAD is validated through a simulated anomalous citation dataset. Experimental results demonstrate the effectiveness of GLAD on the anomalous citation detection task. © 2012 IEEE.

Surveys incorporating the Revised Study Process Questionnaire (R-SPQ-2F) were conducted with 156 CIS and 212 ADS from two Australian universities. The findings demonstrated that perceived disparities existed between the two cohorts in terms of their approaches to learning. These disparities, however, did not support the well-documented view of CIS as mainly surface oriented learners but rather as more rounded learners than ADS in their learning approaches. This study gave voice to CIS to reflect on their learning in Australian universities, in conjunction with and supplemented by insights provided by their Australian student counterparts.

- Description: In the typical scenario of the Internet of Vehicles (IoV), the edge servers (ESs) are laid out near the road side units (RSUs) to process the collected data for a variety of IoV services in real time. Generally, because ESs are lightweight compared with cloud servers, if the ESs are not appropriately distributed, it will cause the unbalanced workload of the ESs. Thus, developing an ES plan to avoid the risk of overload and improve the quality of service (QoS) remains a challenge. To tackle it, a deep reinforcement learning-based multi-objective edge server placement strategy, named DESP, is fully explored, to promote the coverage rate, the workload balancing and reduce the average delay of finishing tasks in the IoV. In particular, the Markov Decision Process (MDP) of the ES placement problem is formulated and the deep reinforcement learning, i.e., Deep Q-Network (DQN) is applied to obtain the optimal placement scheme achieving the multiple objectives above. At last, a real vehicular data set is used for assessing the validity of DESP. © 2022 Elsevier B.V.

After duplicate removal, all publications went through title and abstract screening followed by full text review and inclusion of articles in the review against the selection criteria. A narrative synthesis describes the time points, intervals and measurement guidelines used by the included articles. Results A total of 2113 articles were identified from the initial search. Finally, 68 articles were included for data charting process. Eight time points and 14 intervals were identified as the most common events researched by the articles. Eighteen different lung cancer care guidelines were used to benchmark intervals in the included articles; all were developed in Western countries. The British Thoracic Society guideline was the most frequently used guideline (20%). Western guidelines were used by the studies in Asian countries despite differences in the health system structure. Conclusion This review identified substantial variations in definitions of some of the intervals used to describe timeliness of care for lung cancer. The differences in healthcare delivery systems of Asian and Western countries, and between high-income countries and low-income-middle-income countries may suggest different sets of time points and intervals need to be developed. ©

- Description: Objectives Early diagnosis and reducing the time taken to achieve each step of lung cancer care is essential. This scoping review aimed to examine time points and intervals used to measure timeliness and to critically assess how they are defined by existing studies of the care seeking pathway for lung cancer.

- Description: Context: Invasive species are major drivers of biodiversity loss, requiring management to reduce their ecological impacts. Population genetics can be applied to delineate management units, providing information that can help plan and improve control strategies. Aim: The present study aims to use a genetic approach to test the existence of three previously proposed sambar deer populations in south-eastern Australia. In doing so, the study aims to delineate management units of sambar deer in south-eastern Australia. Methods: Sambar deer DNA was sourced opportunistically from tissue samples and targeted scat collection. Samples were collected from three areas in Victoria, south-eastern Australia: Mt Cole (MC), French Island (FI) and eastern Victoria (EV). Contemporary population structure was assessed using a suite of 11 polymorphic microsatellite markers. The number of maternal sambar deer lineages in south-eastern Australia was investigated through sequencing of the mitochondrial (mt)DNA control region. Key results: Three distinct genetic clusters were identified. Differentiation among inferred clusters was found to be high, with FST ranging from 0.24 between EV and FI clusters and 0.48 between MC and FI clusters. Two mtDNA haplotypes were identified; R.u1 was found throughout EV and FI, and R.u2 was unique to MC. DNA isolated from scats provided reliable data and proved critical for sampling areas where hunting and culling of deer are not generally undertaken. Conclusions: Three genetically distinct sambar deer management units in south-eastern Australia are defined-MC, FI and EV. Sambar deer control strategies should be applied to each management unit independently. This may be difficult or infeasible for the EV management unit, which is large and geographically complex. Further research may help identify additional fine-scale genetic structure in EV, allowing smaller, more practicable management units to be identified. Implications: Genetic data can be used to identify management units for invasive species, which will be critical for the development of future management strategies and improving control operations. The approach outlined here could also be applied to improve the management of other introduced deer species in south-eastern Australia. © 2022 CSIRO Open Access.

- Description: We examined the density, diversity, and seasonal fluctuation of soil inhabiting Collembola in different ecosystems: agricultural, rangeland, and forest ecosystems in the North Khorasan province of Iran from June 2018 to May 2019. The sampling program was conducted monthly on the three sites. Density was measured on the number of individuals per square meter. Species diversity was calculated using Shannon–Wiener index, Simpson’s diversity, and species richness by Rarefaction method. Fifty-three species belonging to 42 genera and 17 families were collected and identified. The density of Collembola in the forest was higher than in either rangeland or agroecosystem. Highest densities were recorded during October and April in the forest. A similar seasonal trend was observed in the rangeland and in the agroecosystem. The lowest densities in agroecosystem and rangeland were recorded during June and from forest in January. PERMANOVA analysis showed that the soil Collembola community differed between the three ecosystems. The SIMPER analysis revealed that the agriculture sites show the highest similarity (68.3), followed by pasture (51.8), and then forest (49.7). Indices of diversity and species richness values are discussed in light of land use. We found that forest harboured a higher density and diversity of Collembola compared to rangeland and agroecosystems. © TÜBİTAK.

- Description: The limaçon positive displacement machine is characterised by its internal geometry and unique mechanical motion; both based on a mathematical curve known as the limaçon of Pascal. The limaçon technology offers many advantages, such as compact size and double‐acting functionality, and its great potential for fluid processing applications has been proven by a number of patents and innovative designs in engines, expanders, and pumps. However, no commercial application of the limaçon technology in the field of positive displacement compressors has been reported in the literature. This could be attributed to the fact that the potential of the limaçon technology for gas compression has not been established as yet. The process of establishing potential is necessary before funds and resources are dedicated to investing in prototyping and testing. This process entails a considerable amount of modelling, coding and analysis as one must ensure the embodiment is geometrically capable of delivering suction and compression strokes, ports can be arranged to support the workings of these strokes, a number of measurable parameters can be identified as impacting compressor performance and it is possible to calculate a set of parameters which optimise this performance. To achieve this objective, a comprehensive mathematical model of a limaçon machine, implemented as a compressor,was first developed. The model, which is multi‐physical in nature, spans such domains as kinematics, fluid dynamics, characteristics of the port flow, internal leakage due to seal vibration, dynamics of the discharge valve, and thermodynamics. Subsequently, the simulation of the model has been performed to numerically study the operational characteristics of the limaçon compressor and to investigate the effect of various parameters on the compressor performance. It was found that the increase in the operating speed and pressure ratio would lead to negative effects on machine performance, especially on volumetric efficiency. Additionally, the results of simulations indicated that the level of fluid over‐compression is influenced by the characteristics of the discharge valve. To ensure the suitability of limaçon technology for use in positive displacement compressors, a study was undertaken to determine whether such an embodiment lent itself to optimisation efforts. For this purpose, the thorough mathematical model which has been developed to simulate compressor workings was then used for optimisation purposes whereby a Bayesian optimisation procedure was applied. The optimisation procedure was conducted in a two‐stage fashion where the first stage optimises the machine dimensions to meet volumetric requirements specified by the designer; and the second stage focuses on revealing the optimum combination of port geometries that improves machine performance. A numerical illustration was presented to prove the validity of the presented approach, and the results show that considerable improvements in the isentropic and volumetric efficiencies can be attained. Moreover, the optimised design was tested under different operating speeds and pressure ratios to investigate its robustness. It was found that the optimised design can exhibit relatively stable performance when the working conditions vary within a small bandwidth around that used in the optimisation procedure. The limaçon technology has three embodiments, namely the limaçon‐to‐limaçon (L2L), the limaçon‐to‐circular, and the circolimaçon. The circolimaçon embodiment features using circular arcs, rather than limaçon curves, to develop profiles for the rotor and housing. This embodiment simplifies the manufacturing process and reduces the production cost associated with producing a limaçon technology. A feasibility study of the circolimaçon embodiment was conducted by comparing its performance with that of the L2L type device. The machine dimensions and port geometries obtained from the optimisation procedure were used in the comparative study. A nonlinear three‐degree of freedom model was presented to describe the dynamic behaviour of the apex seal during the machine operation. Additionally, the leakage through the seal‐housing gap was formulated by considering the inertia and viscous effects of the flow. The results from the case study suggest that the circolimaçon embodiment exhibits comparable performance to the L2L‐type machine, despite having more significant seal vibrations. Moreover, it was also discovered that the circolimaçon compressor with a small capacity undergoes a lower level of seal dynamics, indicating better machine reliability.

- Description: During COVID-19, consumers of skincare products pay more attention to safety and comfort. In such a crisis, consumers seek skincare products with brand effectiveness, high quality, and persuasive reviews by social media influencers. This study investigates the influence of brand effectiveness, product quality, and celebrity endorsers on purchase intention of halal skincare products in the pandemic. The study employed a survey of halal skincare users in East Java, Indonesia. A purposive sampling of 180 female respondents was analyzed; they were followers of Safi-Skincare Instagram and aged 18 and over. Descriptive statistics indicated that religious background strengthened the factors influencing the purchase intention towards a skincare product. The data were then analyzed using multiple linear regression with a statistical level of confidence of 95%. The result showed that brand effectiveness, product quality, and celebrity endorsers significantly affect purchase intention in Indonesia during the pandemic. The study concludes that Muslim standards reinforce rigid standards applied to skincare products with a halal logo, supporting good quality performance and encouraging stronger purchase intention. This study contributes to understanding consumer behavior in the pandemic using a purchase intention framework that can be applied to the safety and comfort of other consumer products. © Sudaryanto Sudaryanto, Jerry Courvisanos, Ivana Rosediana Dewi, Rusdiyanto Rusdiyanto, Jiva Rendis Yuaris, 2022

- Description: The FAIR (findable, accessible, interoperable, and re-usable) principles and practice recommendations provide high level guidance and recommendations that are not research-domain specific in nature. There remains a gap in practice at the data provider and domain scientist level demonstrating how the FAIR principles can be applied beyond a set of generalist guidelines to meet the needs of a specific domain community. We present our insights developing FAIR thresholds in a domain specific context for self-governance by a community (agricultural research). ‘Minimum thresholds’ for FAIR data are required to align expectations for data delivered from providers’ distributed data stores through a community-governed federation (the Agricultural Research Federation, AgReFed). Data providers were supported to make data holdings more FAIR. There was a range of different FAIR starting points, organisational goals, and end user needs, solutions, and capabilities. This informed the distilling of a set of FAIR criteria ranging from ‘Minimum thresholds’ to ‘Stretch targets’. These were operationalised through consensus into a framework for governance and implementation by the agricultural research domain community. Improving the FAIR maturity of data took resourcing and incentive to do so, highlighting the challenge for data federations to generate value whilst reducing costs of participation. Our experience showed a role for supporting collective advocacy, relationship brokering, tailored support, and low-bar tooling access particularly across the areas of data structure, access and semantics that were challenging to domain researchers. Active democratic participation supported by a governance framework like AgReFed’s will ensure participants have a say in how federations can deliver individual and collective benefits for members. © 2022 The Author(s).
