- Description: While established in Asia, rice koji and miso are fermented foods that are becoming more popular in western countries. They have been shown to contain a variety of microorganisms, consisting of bacteria, yeasts, and fungal species. Many contemporary miso varieties are not pasteurized as consumers are looking for more natural products, and/or have the desire to consume fermented foods containing live microorganisms. While correctly prepared fermented foods are rarely associated with food safety outbreaks, incidences have been recorded. On these occasions, pathogenic, or spoilage microorganisms were introduced into the products from external sources such as the raw material or the processing environment. Consequently, hygiene and fermentation conditions need to be carefully monitored to ensure food safety. Furthermore, many of the production steps during koji and miso manufacture do not fit into contemporary food safety guidelines for foods. Although pH is a required food safety hurdle for fermented foods, this does not apply to nonacidic foods such as koji or miso. This review focuses on control of microbial pathogens and discusses the processes of miso fermentation, and how fermentation of rice koji and miso fits with current food safety hurdles in western countries. © 2023 The Authors.

- Description: Strongyloidiasis is a World Health Organization neglected tropical disease usually caused by Strongyloides stercoralis, a parasitic worm with a complex life cycle. Globally, 300-600 million people are infected through contact with fecally contaminated soil. An autoinfective component of the life cycle can lead to chronic infection that may be asymptomatic or cause long-term symptoms, including malnourishment in children. Low larval output can limit the sensitivity of detection in stool, with serology being effectivebut less sensitive in immunocompromise. Host immunosuppression can trigger catastrophic, fatal hyperinfection/dissemination, where large numbers of larvae pierce the bowel wall and disseminate throughout the organs. Stable disease is effectivelytreated by single-dose ivermectin, with disease in immunocompromised patients treated with multiple doses. Strategies for management include raising awareness, clarifying zoonotic potential, the development and use of effectivediagnostic tests for epidemiological studies and individual diagnosis, and the implementation of treatment programs with research into therapeutic alternatives and medication safety. © 2023 American Society for Microbiology.

- Description: Background: Clinical practice guidelines (CPGs) are used to guide decision-making, especially regarding complementary and alternative medicine (CAM) therapies that are unfamiliar to orthodox healthcare providers. This systematic review aimed to critically review and summarise CAM recommendations associated with anxiety management included in the existing CPGs. Methods: Seven databases, websites of six international guidelines developing institutions, and the National Centre for Complementary and Integrative Health website were systematically searched. Their reporting and methodological quality were evaluated using the Reporting Items for practice Guidelines in Healthcare checklist and the Appraisal of Guidelines for Research and Evaluation (2nd version) instrument, respectively. Results: Ten CPGs were included, with reporting rates between 51.4 and 88.6%. Seven of these were of moderate to high methodological quality. Seventeen CAM modalities were implicated, involving phytotherapeutics, mind–body practice, art therapy, and homeopathy. Applied relaxation was included in 70% CPGs, which varied in degree of support for its use in the treatment of generalised anxiety disorder. There were few recommendations for other therapies/products. Light therapy was not recommended for use in generalised anxiety disorder, and St John’s wort and mindfulness were not recommended for use in social anxiety disorder in individual guidelines. Recommendations for the applicability of other therapies/products for treating a specific anxiety disorder were commonly graded as “unclear, unambiguous, or uncertain”. No CAM recommendations were provided for separation anxiety disorder, specific phobia or selective mutism. Conclusion: Available guidelines are limited in providing logically explained graded CAM recommendations for anxiety treatment and care. A lack of high-quality evidence and multidisciplinary consultation during the guideline development are two major reasons. High quality and reliable clinical evidence and the engagement of a range of interdisciplinary stakeholders are needed for future CPG development and updating.

- Description: Background: There is a need for evidence-informed guidance on the use of complementary and alternative medicine (CAM) for insomnia because of its widespread utilization and a lack of guidance on the balance of benefits and harms. This systematic review aimed to identify and summarize the CAM recommendations associated with insomnia treatment and care from existing comprehensive clinical practice guidelines (CPGs). The quality of the eligible guidelines was appraised to assess the credibility of these recommendations. Methods: Formally published CPGs incorporating CAM recommendations for insomnia management were searched for in seven databases from their inception to January 2023. The NCCIH website and six websites of international guideline developing institutions were also retrieved. The methodological and reporting quality of each included guideline was appraised using the AGREE II instrument and RIGHT statement, respectively. Results: Seventeen eligible GCPs were included, and 14 were judged to be of moderate to high methodological and reporting quality. The reporting rate of eligible CPGs ranged from 42.9 to 97.1%. Twenty-two CAM modalities were implicated, involving nutritional or natural products, physical CAM, psychological CAM, homeopathy, aromatherapy, and mindful movements. Recommendations for these modalities were mostly unclear, unambiguous, uncertain, or conflicting. Logically explained graded recommendations supporting the CAM use in the treatment and/or care of insomnia were scarce, with bibliotherapy, Tai Chi, Yoga, and auriculotherapy positively recommended based on little and weak evidence. The only consensus was that four phytotherapeutics including valerian, chamomile, kava, and aromatherapy were not recommended for insomnia management because of risk profile and/or limited benefits. Conclusions: Existing guidelines are generally limited in providing clear, evidence-informed recommendations for the use of CAM therapies for insomnia management due to a lack of high-quality evidence and multidisciplinary consultation in CPG development. More well-designed studies to provide reliable clinical evidence are therefore urgently needed. Allowing the engagement of a range of interdisciplinary stakeholders in future updates of CPGs is also warranted.

- Description: Soil moisture is a major limiting factor in most dryland agricultural production systems around the globe. In dryland agriculture the amount of water available to grow a crop is determined primarily by the in-season rainfall and the amount of water stored in the soil profile prior to seeding of the crop. Soil water content and water storage capacity are key parameters. Soil moisture data measurements are a compromise between the spatial scale of the investigated site, the required spatial resolution, and the depth of investigation of the applied method. A bibliographic search of the measurement of soil moisture content at field-scale was done, giving an overview of current practices available to determine the spatial variability within a field, and its applicability to farm management practices. Articles published between April 2013 and March 2023 were searched, retaining only the articles with horizontal resolution less than or equal to 100 m, minimum vertical support at a depth greater than or equal to 30 cm from the soil surface, a minimum of two vertical layer depths, and the topic of the document was associated with the measurement of soil moisture at field-scale. The results of this review highlight progress in the past decade but currently there is no one method that can achieve absolute continuous spatial soil moisture in 3D at the field level. Some areas of research show promise but is still some distance away from a reliable, timely, and accurate soil moisture mapping required for many extensive dryland farming systems. © 2023

- Description: Blasting constitutes an essential component of the mining and construction industries. However, the associated nuisances, particularly blast vibration, have emerged as significant concerns that pose threats to operational stability and the safety of the surrounding areas. Given the increasing emphasis on sustainability, ecological responsibility, safety, and geo-environmental practices, the impact of blast vibration has garnered heightened attention and scrutiny. Nevertheless, the field still lacks comprehensive phase analysis studies. Therefore, it is imperative to elucidate the research progress on blast vibration and discern its current frontiers of investigation. To address this need, this study employs bibliometric methods and the CiteSpace 6.1.R2 software to analyze 3093 papers from the Web of Science database. Through this comprehensive analysis, the study aims to chronicle the developmental trajectory, assess the present research status, and identify future trends in the field of blast vibration. The findings of this study reveal that research on “blasting vibration” is advancing rapidly, with the number of citations exhibiting a J-shaped growth curve over time. China emerges as the leading contributor to this research, followed by India, and the foremost institution in this field is Central South University in China. Cluster analysis identifies the effects of ground vibration, numerical simulation, blast load, blasting vibration and rockburst hazard as the most prominent research areas presently. The primary research directions in this domain revolve around the rock fragmentation, compressive strength, particle swarm optimization, and ann. The emergence of these keywords underscores a dynamic shift towards a more holistic and multidisciplinary approach in the field of blasting-induced ground vibration. Furthermore, this study provides a concise overview of blast vibration, discusses prediction techniques, and proposes measures for its control. Additionally, the discussion delves into the social significance of intelligent blasting systems within the context of artificial intelligence, aiming to address the hazards associated with blast-induced ground vibrations. © 2023, The Author(s), under exclusive licence to Springer-Verlag GmbH Germany, part of Springer Nature.

- Description: CONTEXT: Continued increases in global population and rising living standards in many countries are driving a surge in demand for energy and protein-rich foods. Wheat, barley, and canola are important crops that are grown and traded globally. However, climate change, geopolitical tensions and competition from other crops threaten the ability to satisfy global demand. Accurate predictions of crop production and its spatial variation can play a significant role in their reliable and efficient production, marketing, and distribution. OBJECTIVE: This review examined recently published models and data used to predict wheat, barley, and canola yield to identify which factors produced the best yield predictions. METHODS: A literature search was conducted across the Scopus, EBSCOhost and Web of Science databases over seven years between 2015 and 2021. Data extracted from the papers identified by the literature search were investigated using graphical and quantitative analytical techniques to determine if the type of algorithm, input data, prediction timing, output scale or extent and climate variability both in isolation and in combination affected the model's predictive ability. RESULTS AND CONCLUSIONS: The literature search produced 11, 908 results which was reduced to 118 papers after applying the review criteria (peer reviewed papers focussed on models predicting yield at greater than plot scale across extensive areas using accessible data). China produced almost one third of all yield prediction models over the study period and 87% of models were used to predict wheat yield. Statistical models were the most common algorithm in most regions and in total. However, there was a surge in machine learning models after 2018. They were the most common model from 2019 to 2021, with one third developed in China. The review concluded that only the choice of modelling technique and the input data had a significant effect on model performance with the machine learning techniques Random Forest, Boosting algorithms and Deep Learning models as well as process-based Light Use Efficiency models that used a combination of remotely sensed and agrometeorological data performing best. SIGNIFICANCE: The review showed that matching the model to the available data could improve the ability to predict wheat, barley or canola yield. The use of quantitative statistical techniques in this review, should give modellers trying to predict wheat, barley or canola yield more confidence in matching their approach to the available data than previous reviews that relied on visual interpretation of data. © 2023 The Authors

- Description: Aim: To explore, identify and integrate the existing knowledge to categorise the characteristics, likelihood, and consequences of workplace incivility among newly qualified graduate registered nurses. A particular focus of this review is on the experiences of new nurses related to these negative workplace behaviours and the strategies employed by these nurses and their organisations to manage workplace incivility. Background: Workplace incivility has been widely recognised as a global problem in healthcare settings and is known to affect nurses in all facets of their professional and personal life. This might be particularly harmful for newly qualified graduate nurses, as they are unprepared to deal with this uncivil culture. Design: An integrative review of the global literature, conducted according to the Whittemore and Knafl framework. Methods: Database searches (CINAHL, OVID Medline, PubMed, Scopus, Ovid Emcare and PsycINFO), and manual searching generated an aggregate of 1904 articles, which were further screened based on inclusion criteria and eligibility using the Mixed Methods Appraisal Tool (MMAT). Peer-reviewed empirical studies that explored the workplace incivility experiences of new graduate nurses were included in this review. Extracted data were grouped to develop themes and sub-themes. Results: This review included 14 studies in total with seven quantitative and seven qualitative studies. The data collected from these studies were categorised according to the research questions into a) expectations of civility, b) experiences and exposure to workplace incivility, c) forms and characteristics of incivility, d) sources of incivility, e) consequences of incivility, and f) managing and coping with incivility. Across studies, graduate nurses' views about the prestige and power of the nursing profession are conflicted due to experiences of incivility in clinical practice. New graduate nurses experienced a high but variable prevalence of incivility from their co-workers (25.6–87 %), with manifestations of incivility varying greatly, including eye rolling, yelling, exclusion and sexual harassment. Included studies primarily focused on professional and organisational effects and their outcomes relative to the physical and psychological effects on new nurses. Conclusion: Findings from the literature demonstrate that incivility directed toward newly qualified graduate nurses is prevalent and can have significant negative impact on their self-esteem and confidence, which may ultimately impact on their workforce participation decisions and the quality of patient care. Supportive and empowering work environments are vital not only for improved nurse health and well-being, but also to retain new graduate nurses. The current nursing shortage emphasises the need for such conditions. © 2023 Elsevier Ltd

- Description: Background: The nematode, Caenorhabditis elegans has proven itself as a valuable model for investigating metazoan biology. C. elegans have a transparent body, an invariant cell lineage, and a high level of genetic conservation which makes it a desirable model organism. Although used to elucidate many aspects of somatic biology, a distinct advantage of C. elegans is its well annotated germline which allows all aspects of oogenesis to be observed in real time within a single animal. C. elegans hermaphrodites have two U-shaped gonad arms which produce their own sperm that is later stored to fertilise their own oocytes. These two germlines take up much of the internal space of each animal and germ cells are therefore the most abundant cell present within each animal. This feature and the genetic phenotypes observed for mutant worm gonads have allowed many novel findings that established our early understanding of germ cell dynamics. The mutant phenotypes also allowed key features of meiosis and germ cell maturation to be unveiled. Summary: This review will focus on the key aspects that make C. elegans an outstanding model for exploring each feature of oogenesis. This will include the fundamental steps associated with germline function and germ cell maturation and will be of use for those interested in exploring reproductive metazoan biology. Key Messages: Since germ cell biology is highly conserved in animals, much can be gained from study of a simple metazoan like C. elegans. Past findings have enhanced understanding on topics that would be more laborious or challenging in more complex animal models. © 2023 The Author(s). Published by S. Karger AG, Basel.

Key Messages: Since germ cell biology is highly conserved in animals, much can be gained from study of a simple metazoan like C. elegans. Past findings have enhanced understanding on topics that would be more laborious or challenging in more complex animal models. © 2023 The Author(s). Published by S. Karger AG, Basel.

- Description: Patient navigation is a strategy for overcoming barriers to reduce disparities and to improve access and outcomes. The aim of this umbrella review was to identify, critically appraise, synthesize, and present the best available evidence to inform policy and planning regarding patient navigation across the cancer continuum. Systematic reviews examining navigation in cancer care were identified in the Cochrane Central Register of Controlled Trials (CENTRAL), PubMed, Embase, Cumulative Index of Nursing and Allied Health (CINAHL), Epistemonikos, and Prospective Register of Systematic Reviews (PROSPERO) databases and in the gray literature from January 1, 2012, to April 19, 2022. Data were screened, extracted, and appraised independently by two authors. The JBI Critical Appraisal Checklist for Systematic Review and Research Syntheses was used for quality appraisal. Emerging literature up to May 25, 2022, was also explored to capture primary research published beyond the coverage of included systematic reviews. Of the 2062 unique records identified, 61 systematic reviews were included. Fifty-four reviews were quantitative or mixed-methods reviews, reporting on the effectiveness of cancer patient navigation, including 12 reviews reporting costs or cost-effectiveness outcomes. Seven qualitative reviews explored navigation needs, barriers, and experiences. In addition, 53 primary studies published since 2021 were included. Patient navigation is effective in improving participation in cancer screening and reducing the time from screening to diagnosis and from diagnosis to treatment initiation. Emerging evidence suggests that patient navigation improves quality of life and patient satisfaction with care in the survivorship phase and reduces hospital readmission in the active treatment and survivorship care phases. Palliative care data were extremely limited. Economic evaluations from the United States suggest the potential cost-effectiveness of navigation in screening programs. © 2023 The Authors.

Understanding quality standards and simulation best practices used to guide the simulation activities also featured. Eight data bases were searched using a standardized search strategy. A total of 33 studies met the inclusion criteria. Six patient safety standards featured in over 38 simulation scenarios, particularly the management of deteriorating patients. Students’ patient safety knowledge and simulated performances consistently returned significant gains following the interventions. Manikin-based, face to face delivery was the most commonly described simulation modality, followed by virtual simulation and virtual reality programmes. The evidence supports simulation as a beneficial technique for teaching patient safety in nursing education. In future, well planned controlled experimental studies are needed to deliver more evidence.

- Description: Purpose: This paper aims to identify health-care entitlements that exist for asylum seekers with chronic non-communicable disease (CNCD) that promote their health and self-care, and to explore health policies, initiatives and programmes with the potential to foster self-care in this populace. Design/methodology/approach: Narrative review of literature conducted by searching EMBASE, CINAHL, WEB OF SCIENCE and PSYCINFO databases for articles published from 2010 to 2021. Included articles focussed on policies, programmes or initiatives with the potential to promote health in adult asylum seekers residing in high-income countries. Studies inclusive of other migrant groups such as undocumented migrants and those with mental health conditions were excluded. Eleven studies fitting the inclusion criteria were assessed against the study objectives. Findings: Free access to health-care services and pharmaceutical products, free access to food banks and supermarket model food banks, English and cooking lessons, community integration training sessions and culturally competent health-care workers were found to promote health and self-care. There is little research on self-care and health promotion in adult asylum seekers with CNCD. CNCDs represent high burden of disease in asylum seekers but have a low priority in reported research. Originality/value: This narrative review is the first to explicitly focus on asylum seekers in high-income countries with CNCD, excluding mental health conditions, and to explore initiatives, programmes and policies that enhance health promotion to facilitate self-care in this populace. © 2021, Emerald Publishing Limited.

- Description: Introduction: Student satisfaction is an important quality indicator in higher education, impacting student retention and institutional rankings. Healthcare education literature lacks factors related to student satisfaction. Reporting these elements might assist educators in curriculum design that helps to retain students. This is imperative for nursing education with the current global need for graduates. Objectives: To explore, synthesize and report available evidence on conceptual elements underlying the formation of higher education students' satisfaction, with a focus on nursing education. Design: Integrative review. Data sources: Six databases were searched for learner experiences of satisfaction: MEDLINE, Academic Search Complete, CINAHL Complete, ERIC, APA PsychArticles, PsychInfo. Articles were screened, assessed for quality and 12 nursing student studies and 10 conceptual studies of mixed student cohorts were reviewed. Review methods: Peer-reviewed literature in English during the period 2012 to 2022 was reviewed using methods documented for an integrative review. Results: Twenty-two included studies were mostly quasi-experimental, based on statistical analysis of higher education student surveys. Antecedent elements affecting satisfaction in mixed student cohorts were Service Quality, Institutional Image and perceived Value. These studies identified up to seven dimensions underlying student satisfaction. Nursing studies were focused on the quality of service delivery related to teaching and confirmed five elements: Faculty, Learning environment, Curriculum, Social interaction and Development. Conceptual studies also reported ‘consequent’ elements, high satisfaction resulting in positive student behavioural intent, loyalty and positive word of mouth. The details of antecedent and consequent elements that underlie student satisfaction are described. Conclusion: Conceptual studies of mixed student cohorts identified nine elements that inform student satisfaction with learning experiences. Nursing student studies tested fewer variables and confirmed up to five elements forming student satisfaction. There is a need to investigate the impact of additional key elements in nursing students - perceptions of value, institutional image and administrative support. © 2023 The Authors

- Description: Among the multitude of alternate plasticity index (PI) estimation proposals, empirical correlations based on the linear shrinkage (LS) test, originally proposed in the 1967 edition of the British BS 1377 standard, seem to be gaining increased attention. This study has two main aims: (i) re-examining LS-based correlations for PI estimation to better understand their true potentials and/or limitations; and (ii) investigating the possibility of employing LS, as a proxy for the standard PI, for fine-grained soil classification. To this end, comprehensive statistical analyses were performed on the largest and most diverse database assembled of its kind, entailing PI:LS measurements for 265 different fine-grained soils [pertaining to the ‘soft’ base percussion-cup liquid limit (LL = 17–134%) and the Australian standard LS = 0.5–32.0%]. It was demonstrated that the LS can generally only provide a rough approximation of the actual PI. At best, only those predictions produced by PI = 1.86 × LS for low-plasticity soils (i.e., LL

- Description: Returning to sport and exercise following injury requires the athlete to become more confident in the ability to gradually explore the use of the injured area in increasingly complex and challenging ways. Emotional responses, such as fear of re-injury, are a key mental health barrier to a performer's return to sport and exercise. To navigate such psychological responses, performers need well-developed psychological strategies, like mental imagery (MI), to facilitate a successful return to pre-injury levels of sport and exercise. MI is a well-established strategy for dealing with negative symptoms associated with injury, providing a safe and less intimidating environment to practice movements that may be perceived as risky and otherwise performed within physical training due to the fear of causing further injury. This paper aims to provide sport psychologists with recommendations on how to utilize MI to reduce fear of re-injury during the rehabilitation process to successfully facilitate return to sport and exercise. Specific examples are also outlined and discussed. © 2023 Walter de Gruyter GmbH, Berlin/Boston.

- Description: The present study aims to explore the utility of the Team Emergency Assessment Measure (TEAM) in relation to the enhancement of emergency team non-technical skills based on research conducted over the last decade. In this mapping review, a citation mining process identified 22 primary studies for inclusion, published between 2012 and 2022. It provides outcome data on emergency teams' non-technical skills following team training and/or real-life patient emergencies. Emergency team studies related to resuscitation teams (adult, paediatric, newborn and obstetric cases) and medical emergency team (MET) management of patient deterioration. Team performance ratings varied, ranging from approximately 90% for experienced clinical teams down to 38% for students. Statistically significant improvements in performance were notable following training and/or repeated practice. Validity evidence, across 11 studies that provided change data described positive learning outcomes and moderate intervention effects. However, according to Kirkpatrick's model of educational evaluation the studies were limited to professional development phases of learning and immediate post-training assessments rather than care quality improvement. The review highlights a lack of studies evidencing quality improvement or clinical impact such as change of patient care practice or health service performance. There is a need to conduct well-designed studies that explore both technical and non-technical skills of resuscitation teams and METs. Currently, non-technical skills training and repeated performance evaluations using the TEAM contribute immensely to the proficiency of emergency teams. © 2023 The Authors.

- Description: Communication protocols play a pivotal role in the substation automation system as they carry critical information related to asset control, automation, protection, and monitoring. Substation legacy protocols run the assets’ bulk data on multiple wires over long distances. These data packets pass through multiple nodes, which makes the identification of the location and type of various malfunctions a challenging and time-consuming task. As downtime of substations is of high importance from a regulatory and compliance point of view, utilities are motivated to revisit the overall scheme and redesign a new system that features flexibility, adaptability, interoperability, and high accuracy. This paper presents a comprehensive review of various legacy protocols and highlights the path forward for a new protocol laid down as per the IEC 61850 standard. The IEC 61850 protocol is expected to be user-friendly, employ fiber optics instead of conventional copper wires, facilitate the application of non-conventional instrument transformers, and connect Ethernet wires to multiple intelligent electronic devices. However, deployment of smart protocols in future substations is not a straightforward process as it requires careful planning, shutdown and foreseeable issues related to interface with proprietary vendor equipment. Along with the technical issues of communication, future smart protocols call for advanced personnel and engineering skills to embrace the new technology. © 2023 by the authors.

- Description: The microgrid (MG) system is a controlled and supervised power system consisting of renewable energy (RE)-based distributed generation (DG) units, loads, and energy storage. The MG can be operated autonomously or while connected to the grid. Higher intermittencies and uncertainties can be observed in MGs compared to the conventional power system, which is the possible source of small-signal stability in MG systems. It can be seen as disturbances around the stable operating point, which potentially lead to the small-signal instability problem within MGs. Small-signal instability issues also emerge due to the lack of damping torque in the MG. The integration of power electronic devices and complex control algorithms within MGs introduces novel challenges in terms of small-signal stability and possible resonances. The occurrence of interaction in a low- or no-inertia system might worsen the stability margin, leading to undamped oscillatory instability. The interaction within the MG is characterized by various frequency ranges, from low-frequency subsynchronous oscillation to high-frequency ranges around the harmonic frequencies. This study presents an overview of the dynamic model, possible sources of small-signal instability problems, and resonance phenomena in MGs. The developed models of MG, including structure, converter-based power generation, and load and control algorithms, are briefly summarized to provide the context of MG system dynamics. A comprehensive critical review of the previous research, including small-signal stability and resonance phenomenon for MGs, is also provided. Finally, key future research areas are recommended. © 2023 by the authors.

- Description: As the smart grid evolves, it requires increasing distributed intelligence, optimization and control. Model predictive control (MPC) facilitates these functionalities for smart grid applications, namely: microgrids, smart buildings, ancillary services, industrial drives, electric vehicle charging, and distributed generation. Among these, this article focuses on providing a comprehensive review of the applications of MPC to the power electronic interfaces of distributed energy resources (DERs) for grid integration. In particular, the predictive control of power converters for wind energy conversion systems, solar photovoltaics, fuel cells and energy storage systems are covered in detail. The predictive control methods for grid-connected converters, artificial intelligence-based predictive control, open issues and future trends are also reviewed. The study highlights the potential of MPC to facilitate the high-performance, optimal power extraction and control of diverse sustainable grid-connected DERs. Furthermore, the study brings detailed structure to the artificial intelligence techniques that are beneficial to enhance performance, ease deployment and reduce computational burden of predictive control for power converters. © 2022 Elsevier Ltd

- Description: The traditional model of community club-based sport is fine for those, particularly children and youth, who enjoy the competitive focus and have the skills and commitment to play. But societal preferences during leisure time have changed dramatically over recent decades. However, sport organisations have made limited progress in response to these changes in providing ways in which children and youth can participate outside the traditional competitive structures and environments. In this paper the context of community club-based structures is reviewed leading into an assessment of the associated impact of these structures on sport participation. Children and youth's current motivations to play sport including what makes sport fun to play, are considered. It is then demonstrated that the associations between motivations to play sport and the factors that contribute to fun and enjoyment, are often misaligned for many individuals, with a primary focus on competition-based structures to deliver community club sport. In the final part of the paper a model for community sport organisations where people are put first is proposed - Sport4Me. Sport4Me is about flexible, inclusive, equitable sporting opportunities that focus on friends, fun, physical literacy and play. The model would complement the traditional competitive club-based model and afford participants more choice whilst fostering an environment that promotes lifelong involvement in sport. This model will require structural and cultural changes to the sporting environment and include coaching practices. Sport4Me is an evidence-based model, but it is not radical in its conceptualisation but rather, builds on previously proposed approaches, considers the needs and wants of potential sport participants and widens the scope of sport delivery. 2023 Eime, Westerbeek, Pill and Reece.
