Active and reactive power injection of energy storage for short-term frequency stability in islanded power systems
Get PDFFast frequency response (FFR) is crucial to enhance and maintain the frequency stability in power systems with high penetration of converter-interfaced renewable energy sources (RES). Active power based FFR reserves, such as energy storage systems (ESSs), are being considered for this purpose. However, the cost associated with ESS-based FFR reserves can be significantly high due to the high-power capacity associated with the FFR reserves. Therefore, this paper proposes a novel FFR reserve to achieve a techno-economically feasible solution, i.e., to achieve a better or similar service with a smaller size of ESS. Unlike the conventional FFR reserve that just uses active power, the proposed active and reactive power-based FFR reserve (i.e., P-Q-FFR reserve) modulates the grid's active and reactive powers. The challenges associated with the P-Q-FFR reserve design are the estimation of optimal values of MVAr, MW, and MWh to be injected into the system while ensuring the frequency and voltage stabilities at the lowest possible cost. First, a data-driven technique based on frequency dynamic signature (FDS) is developed in this work to identify the suitable location of the P-Q-FFR reserve. Afterward, a two-layered region reduction iterative algorithm (TL-RRIA) is developed to determine the storage size (MW, MWh, and MVAr) for the P-Q-FFR reserve. The proposed solution is tested using the DIgSILENT PowerFactory. Simulation results show the effectiveness of the proposed TL-RRIA and data-driven FDS technique. A techno-economic comparison between the conventional FFR reserve and proposed P-Q-FFR reserve is also presented to show the superiority of the proposed one. © 2024 The Author
Pain management interventions of the non-communicating patient in intensive care : what works for whom and why? A rapid realist review
Get PDFAim: The utility and uptake of pain management interventions across intensive care settings is inconsistent. A rapid realist review was conducted to synthesise the evidence for the purpose of theory building and refinement. Design: A five-step iterative process was employed to develop project scope/ research questions, collate evidence, appraise literature, synthesise evidence and interpret information from data sources. Methods: Realist synthesis method was employed to systematically review literature for developing a programme theory. Data Sources: Initial searches were undertaken in three electronic databases: MEDLINE, CINHAL and OVID. The review was supplemented with key articles from bibliographic search of identified articles. The first 200 hits from Google Scholar were screened. Results: Three action-oriented themes emerged as integral to successful implementation of pain management interventions. These included health facility actions, unit/team leader actions and individual nurses' actions. Conclusion: Pain assessment interventions are influenced by a constellation of factors which trigger mechanisms yielding effective implementation outcomes. Implications: The results have implications on policy makers, health organisations, nursing teams and nurses concerned with optimising the successful implementation of pain management interventions. Impact: The review enabled formation of a programme theory concerned with explaining how to effectively implement pain management interventions in intensive care. Reporting Method: This review was informed by RAMESES publication standards for realist synthesis. Public Contribution: No patient or public contribution. The study protocol was registered in Open Science Framework. 10.17605/OSF.IO/J7AEZ. © 2024 The Authors. Journal of Clinical Nursing published by John Wiley & Sons Ltd
Strategic planning report for the tourism innovation working group : Heyfield & District, 2024
Get PDFTourism is one of six innovation themes identified in the Heyfield and District Context Analysis1, which states the following regarding the opportunity to develop tourism in the area (p. 3): Heyfield’s location, nearby places of scenic beauty, Lake Glenmaggie, forested areas including tracks and trails, can support and add value to tourism ideas. Heyfield is known locally as a Gateway to the Southern Alps. The aim of the Heyfield and District Context Analysis was to “to investigate opportunities that will lead to long-term economic and social benefits, new jobs in sustainable industries, and to support the transition away from native timber harvesting”1. Following the context analysis, the next step for the tourism innovation theme was to identify specific opportunities to leverage the community assets to improve the local economy, employment opportunities and community wellbeing. Through the Heyfield and District’s Local Development Strategy (LDS), a draft for the Heyfield Adventure Hub (Appendix 5) was developed as part of a smart specialisation strategy. An aspect of smart specialisation is identifying where innovative efforts (and funding) should be concentrated. The draft strategy (Appendix 5) represents current efforts by the Heyfield Tourism and Traders Association (HTTA) and the Tourism Innovation Working Group (TIWG) to focus on leveraging natural assets and current businesses to provide a platform for an improved local visitor economy. These efforts are encouraged by current visitor activity through the holiday and long weekend periods and are aimed at developing year-round tourism activity. The proposed Adventure Hub is an adventure and nature-based activity concierge for the Heyfield Region, located in the Wetlands & Information Centre, which, according to the draft strategy, may conduct the following activities: 1. Promote the Heyfield Region and all it has to offer in adventure and nature-based activities and experiences to existing and potential visitors. 2. Link visitors to an adventure together with the relevant information. 3. Hiring out equipment such as mountain bikes or paddleboards to assist visitors experience, their adventure or attract others to deliver services. 4. Work alongside stakeholders to develop and implement new adventure activities fitting in with the Heyfield Region (Heyfield, Cowwarr, Tinamba, Glenmaggie, Coongulla and Licola). This research report represents a community-led study approach, capturing views on local tourism, along with stakeholder and expert views on how to improve the visitor economy, while preserving or enhancing the local culture and the liveability of the region. A brief literature review provides a snapshot of the experiences and lessons learned from towns and regions that have transitioned from extracting resources from nature to support the local economy, to leveraging natural assets for tourism
Does coping style mediate the relationship between knowledge and psychosocial outcomes in women with atrial fibrillation?
No full textIntroduction: In patients affected by atrial fibrillation (AF) disease-specific knowledge and coping style may be associated with psychosocial well-being. This study aimed to determine if coping style (problem-focused, emotion-focused, avoidance-focused) mediated the relationship between patient knowledge and three psychosocial outcomes (anxiety, depression and life satisfaction). Methods: In 2021 a total of 188 women with reported AF, and ages ranging from 18 to 83 years (mean 48.7, sd 15.5 years), completed an online questionnaire consisting of sociodemographic, clinical and AF knowledge questions and psychosocial instruments (Anxiety and depression, the Hospital Anxiety and Depression (HADS) scale; life satisfaction, Satisfaction With Life Scale (SWLS); and coping style (Brief COPE). Using Jamovi statistical software three individual mediational models (for anxiety, depression and life satisfaction) were constructed assessing the direct and indirect relationships between knowledge, coping style and each psychosocial outcome. Age was a covariate in each model. Results: The mediation analyses demonstrated significant direct negative associations between AF knowledge and HADS anxiety and depression and positive associations with SWLS. There were also direct associations between each of the three coping styles and the three psychosocial outcomes. There were significant indirect effects of coping style between AF knowledge and each of the three outcomes confirming partial mediation effects. Discussion: These findings highlight the crucial role of coping style in mediating the association between AF knowledge and psychosocial outcomes. As such, interventions aimed at increasing patient knowledge of AF may be more effective if adaptive problem-solving coping strategies are also demonstrated to these patients. Additionally, modification of maladaptive coping strategies as part of the psychological management of patients with AF is highly recommended.

Does an increase in supraspinatus tendon thickness after swimming increase the likelihood of future shoulder pain?
No full textBackground: Increase in supraspinatus tendon thickness (STT) resulting from swimming practice has been observed in those with a history of shoulder pain. The magnitude of change in STT after a swimming session and its rate of recovery may be an indicator of future shoulder pain incidence. Hypothesis: The supraspinatus tendons that demonstrate a greater increase in thickness as a result of swimming practice will have an increased likelihood of future shoulder pain in a cohort of competitive swimmers over a period of 6 months. Design: Descriptive epidemiology study. Level of Evidence: Level 2b, individual cohort studies. Methods: A cohort of 50 nationally qualified swimmers aged between 14 and 22 years, from 3 open National Swimming Programs in Victoria, Australia, were recruited for this study. Ultrasonographic measurements of swimmers’ STT was obtained of both shoulders, before, immediately after, and 6 hours after a single swimming practice session. Data were recorded of any significant interfering shoulder pain at 3 and 6 months after the initial testing session. Results: Stepwise logistic regression models indicated that significant predictors of the likelihood of experiencing significant interfering pain were sex [significant at 6 months; odds ratio (OR) 4.2] and the extent of change in STT immediately (OR 2.3 and 1.3 per mm at 3 and 6 months, respectively) and 6 hours postpractice (OR 1.9 and 1.5 per mm at 3 and 6 months, respectively). Conclusion: The current data suggest larger increases in tendon thickness after training are associated with an increased likelihood of future shoulder pain. Clinical Relevance: These data may be valuable for monitoring training load and identifying athletes who may have an increased likelihood of shoulder pain. © 2023 The Author(s)
Deepfake video detection : challenges and opportunities
Get PDFDeepfake videos are a growing social issue. These videos are manipulated by artificial intelligence (AI) techniques (especially deep learning), an emerging societal issue. Malicious individuals misuse deepfake technologies to spread false information, such as fake images, videos, and audio. The development of convincing fake content threatens politics, security, and privacy. The majority of deepfake video detection methods are data-driven. This survey paper aims to thoroughly analyse deepfake video generation and detection. The paper’s main contribution is the classification of the many challenges encountered while detecting deepfake videos. The paper discusses data challenges such as unbalanced datasets and inadequate labelled training data. Training challenges include the need for many computational resources. It also addresses reliability challenges, including overconfidence in detection methods and emerging manipulation approaches. The research emphasises the dominance of deep learning-based methods in detecting deepfakes despite their computational efficiency and generalisation limitations. However, it also acknowledges the drawbacks of these approaches, such as their limited computing efficiency and generalisation. The research also critically evaluates deepfake datasets, emphasising the necessity for good-quality datasets to improve detection methods. The study also indicates major research gaps, guiding future deepfake detection research. This entails developing robust models for real-time detection. © The Author(s) 2024
Effects of job crafting and leisure crafting on nurses' burnout : a machine learning-based prediction analysis
Get PDFAim. To explore the status of job crafting, leisure crafting, and burnout among nurses and to examine the impact of job crafting and leisure crafting variations on burnout using machine learning-based models. Background. The prevalence of burnout among nurses poses a severe risk to their job performance, quality of healthcare, and the cohesiveness of nurse teams. Numerous studies have explored factors influencing nurse burnout; however, few involved job crafting and leisure crafting synchronously and elucidated the effect differences of the two crafting behaviors on nurse burnout. Methods. Multicentre cross-sectional survey study. Nurses (n = 1235) from four Chinese tertiary hospitals were included. The Maslach Burnout Inventory-General Survey, the Job Crafting Scale, and the Leisure Crafting Scale were employed for data collection. Four machine learning algorithms (logistic regression model, support vector machine, random forest, and gradient boosting tree) were used to analyze the data. Results. Nurses experienced mild to moderate levels of burnout and moderate to high levels of job crafting and leisure crafting. The AUC (in full) for the four models was from 0.809 to 0.821, among which the gradient boosting tree performed best, with 0.821 AUC, 0.739 accuracy, 0.470 sensitivity, 0.919 specificity, and 0.161 Brier. All models showed that job crafting was the most important predictor for burnout, while leisure crafting was identified as the second important predictor for burnout in the random forest model and gradient boosting tree model. Conclusion. Even if nurses experienced mild to moderate burnout, nurse managers should develop efficient interventions to reduce nurse burnout. Job crafting and leisure crafting may be beneficial preventative strategies against burnout among nurses at present. Implications for Nursing Management. Job and leisure crafting were identified as effective methods to reduce nurse burnout. Nurse managers should provide more opportunities for nurses' job crafting and encourage nurses crafting at their leisure time. © 2024 Yu-Fang Guo et al
The threshold of rural placement frequency and duration : a repeated cross-sectional study examining rural career aspirations among student nurses
Get PDFAim: This study aimed to explore what changes rural placement had on the perceptions of nursing students and the impact of placement frequency and duration on student considerations for rural practice. Background: A strong rural healthcare workforce is a global concern and has led countries to look for creative ways to address this challenge. One approach is to train more health professionals, however, nursing students who grew up or lived in metropolitan or urbanised areas are suggested to be less inclined to pursue a rural career. As such it is posited that recurrent exposure to rural settings may exert a positive impact on future intention for rural practice. However, there is a need to explore the specific thresholds related to both the frequency and duration of rural placement exposure, as well as the cumulative impact multiple rural placements may have on the intention to engage in rural practice. Design: A repeated cross-sectional design. Methods: All nursing students from an Australian regional university were invited to complete an online questionnaire between 2019 and 2023. Demographic and placement specific questions were included. A modified version of the Nursing Community Apgar tool also measured the importance of key variables in rural career decision-making. Data were analysed using independent sample t-tests and one-way ANOVAs. Significance was determined at two-tailed
Cost-effectiveness of telehealth-delivered diet and exercise interventions : a systematic review
Get PDFObjectives: Telehealth is a promising tool for delivering lifestyle interventions for the management of health conditions. However, limited evidence exists regarding the cost-effectiveness of these interventions. This systematic review aimed to evaluate the current literature reporting on the cost-effectiveness of telehealth-delivered diet and/or exercise interventions. Methods: Four electronic databases (PubMed, CENTRAL, CINAHL and Embase) were searched for published literature from database inception to November 2020. This review adhered to the preferred reporting items for systematic reviews and meta-analyses guidelines and the ISPOR Criteria for Cost-Effectiveness Review Outcomes Checklist. The quality of reporting was assessed using the Consolidated Health Economic Evaluation Reporting Standards checklist. The extracted data were grouped into subcategories according to telehealth modality, organised into tables and reported narratively. Results: Twenty-four studies of controlled trials (11 combined diet and exercise, 9 exercise-only and 4 diet-only telehealth-delivered interventions) were included for data extraction and quality assessment. Interventions were reported as cost-effective in 12 studies (50%), five studies (21%) reported inconclusive results, and seven studies (29%) reported that the interventions were not cost-effective. Telephone interventions were applied in eight studies (33%), seven studies (29%) used internet interventions, six studies (25%) used a combination of internet and telephone interventions, and three studies (13%) evaluated mHealth interventions. Quality of study reporting varied with between 54% and 92% of Consolidated Health Economic Evaluation Reporting Standards items reported. Conclusions: This review suggests that telehealth-delivered lifestyle interventions can be cost-effective compared to traditional care. There is a need for further investigations that employ rigorous methodology and economic reporting, including appropriate decision analytical models and longer timeframes. © The Author(s) 2022
