Quantum symmetric analysis of interval-valued mappings based on generalized Hukuhara differences

The primary aim of this investigation is to examine the quantum symmetric differentiability and anti-derivative charac-teristics of interval-valued (I.V.) mappings utilizing generalized Hukuhara differences. Initially, we present the concepts of the I.V. left quantum symmetric derivative operator and offer its characterization. We present the left quantum symmetric integral operator and its essential properties, grounded in the newly proposed derivative operator. Subsequently, we examine their various essential properties. Finally, we present the applications of our proposed operators to integral inequalities concerning I.V. convex mappings and totally ordered convex mappings. Moreover, the validity of our results is corroborated by numerical and graphical representations

Associations between parental perceptions of neighbourhood environment and physical activity in children and adolescents: a systematic review including 149 studies

Background: Parental perceptions of the neighbourhood environment can be of particular importance for physical activity of children and adolescents, because parents act as the gatekeepers of their children’s behaviour. However, knowledge gaps remain regarding the associations between parental perceptions of neighbourhood environment and physical activity among children and adolescents. Therefore, the aim of this study was to systematically review and summarise evidence on the association between parental perceptions of the neighbourhood environment and physical activity among children and adolescents (5 – 17 years of age). Methods: Literature searches were conducted in: CINAHL, Embase, Environmental Science, MEDLINE/PubMed, PsycInfo, Scopus, SPORTDiscus, Transportation Research Information Services, and Web of Science. The associations were coded as: mostly favourable (for 60% – 100% of studies showing a positive association); mostly unfavourable (for 60% – 100% of studies showing a negative association); and mostly non-significant, indeterminate, or inconsistent. Results: Out of 30,162 records identified in the search, 162 papers from 149 studies were included in the review. The most consistent finding was that a greater distance to school is unfavourably associated with active travel. Evidence of this association was found in children (5/7 associations; pooled sample size in the studies showing significant association [n] = 14,113), adolescents (3/4; n = 2328), and mixed-age group (8/13; n = 5410). There was some consistency in evidence on favourable associations of: (1) access to public transport, good street lighting, and presence of crossing guards with active travel among children; (2) access to sports and recreational facilities, parks and/or playgrounds with sports participation among children; and (3) access to sports and recreational facilities, parks, and/or playgrounds with non-type-specific physical activity among adolescents. Several associations were found in individual studies only, while others were mostly non-significant, indeterminate, or inconsistent. The quality of evidence ranged from very low to low. Conclusions: Parental perceptions of traffic safety and access to destinations and services are associated with different types of physical activity among children and adolescents. There is a need for longitudinal and experimental studies, more research among adolescents, more studies from low- and middle-income countries, and exploring a wider range of neighbourhood environment attributes

Continuing the conversation: charting a course for a situated approach to coach education in Australian football

The aim of this study was to explore the benefits, barriers and strategies associated with integrating a situated approach to coach education in Australian football (soccer). To do so, an interpretivist qualitative research design was used, in which a diverse range of credentialed and experienced Australian football coaches, coach educators, coach education managers, and administrators (n = 28) participated in a series of semi-structured interviews. Participants expressed a strong desire for coach education to be grounded in ‘real-world’ coaching contexts, alongside the guidance of mentors to afford coaches a richer landscape to learn the ‘realities of coaching’. Real-world learning experiences were also deemed to be more meaningful and relevant to coaching practice, fostering a deeper and more nuanced understanding of coaching practice, addressing some of the shortcomings associated with Football Australia's current coach education model. However, participants also identified a number of systemic, institutional and cultural barriers associated with integrating a situated approach, including a perceived lack of value placed on coach education by Football Australia, a ‘closed-off’ culture in the coaching community and governance issues related to mentorship. Against the backdrop of these challenges, participants were optimistic about the prospects of integrating a situated approach to coach education in Australian football. As a result, we map out a way forward for a situated approach that focuses on two key strategies: (i) establishing club environments as the primary locus of coach education, and (ii) integrating mentorship as a core pillar of coach education

Development and Validation of Child Observation Checklist for Early Screening of Young Children with Special Needs

Background: Families with young children with developmental disabilities often express concerns about delays in the identification of these and extended waiting times for obtaining assessments, learning support, and rehabilitation services. The identification process must and can be enhanced if preschool teachers have instrumental measures to detect early-stage developmental disabilities and adjustment difficulties in preschool children and, if necessary, to provide these children with prompt and effective support services. Aims: The aim with this study was to develop and validate a screening checklist for teachers to detect developmental delays and adjustment difficulties in Chinese preschool children in Hong Kong. Methods: The participants included 1085 children aged two to six years (including 365 children who were receiving rehabilitation services at the time of the study) and their preschool teachers. The teachers were requested to complete the screening checklist and the Strengths and Difficulties Questionnaire. Results: The results of the Rasch and Confirmatory Factor Analyses supported the unidimensionality of the checklist, with the validated version consisting of fifteen items and five factors. The checklist score was negatively correlated with children’s behavioral problems and effectively differentiated children of different ages and between children receiving and not receiving rehabilitation services. The reliability estimates (internal consistency and test–retest) of this revised checklist were above 0.70. Conclusions: The 15-item checklist is a promising screening instrument for the identification of developmental disabilities and adjustment problems among Chinese preschool children. The use of the checklist has accelerated access to rehabilitation services for children and family caregivers

Climate-Related Perceptions of Young People with Lived Experience of Disasters in Regional and Rural Victoria, Australia

The experiences of young people, particularly young women, in regional and rural communities and their perceptions of, and responses to, the climate crisis are under-researched. This research focuses on young people outside of urban centres. These young people are largely absent from the broader climate conversation, despite the impact of climate-related disasters in their everyday lives. Their experiences sit within the concept of rural as being deficit, disadvantaged and backward when contrasted with the experiences of urban young people and emerging calls to challenge this bias. This paper reports on a small-scale study investigating how young people who have experienced climate-related disasters in regional and rural Victoria perceive the climate crisis, the relationship between climate change and climate-related disasters, and climate action. Qualitative data was collected from interviews with young women aged 18–23 (n = 7) from six different councils/shires in rural and regional Victoria, Australia, which were impacted by bushfires in 2019–2020. The analysis is attentive to the particularities of “place”. The findings provide insight into regional and rural young people’s perceptions of the climate crisis, the connection (or otherwise) to climate-related disasters and climate action. They also reveal their perception of an urban/rural divide concerning climate action tactics and climate mitigation policy. The research highlights the social and material realities of young people’s everyday lives and feelings of stigma and fear, particularly where they perceived a conflict between climate action and the social and economic relations that shape their regional and rural communities

Removing the straight jacket in practice approach: An investigation into coach learning and development in Australian female tennis

Objectives: Applying an ecological dynamics perspective with the Skilled Intentionality Framework, this study examined whether an integrated coach learning and development framework could be successfully implemented in Australian female tennis coaching. Methods: Participants were all females: qualified coaches (N = 4), coach developers (N = 2) and athletes, aged 15–18 years (N = 7). Participants completed an online survey, examining socio-demographics, playing/coaching history and learning outcomes. An ethnographic and action research approach utilising the Learning in Development Research Framework (LDRF) was undertaken over 20 weeks of coach learning and development. Coaches followed two female coach developers (one as the primary investigator) for a minimum of two hours per week (in situ learning), while the coaches worked directly with athletes. To identify influential factors, multiple data collection strategies were employed, including surveys, semi-structured interviews, observations, critical reflections and focus groups. Results: Perceived program benefits (e.g., coach self-confidence and reassurance) and on-court/off-court support were verified within qualitative interview-derived data. Conclusion: Findings identify the positive influence of an integrated coach learning and development framework on continued Australian female coaching career progression, highlighting coach development implications
