Maturity status influences perceived training load and neuromuscular performance during an academy soccer season

Commonly we see large within-age-group variations in physique, including body mass, stature, and percentages of predicted adult height, which suggests that age-specified training loads are flawed. Aims were to investigate how maturation impacts training load and neuromuscular response within academy soccer and, to provide recommendations for practitioners. Fifty-five male soccer players (age 14.5 ± 1.2 years; stature 172 ± 10 cm; body mass 59.8 ± 10 kg; 94.1 ± 1.8 % predicted adult height) reported differential ratings of perceived exertion (AU) across a season. Neuromuscular performance (countermovement jump, reactive strength index, absolute and relative leg stiffness) was measured using at three timepoints across the season. Perceived exertion and neuromuscular performance were examined using linear mixed modelling, supplemented with non-clinical magnitude-based decisions. Analysis indicates every 5% increase in maturity status results in players perceiving overall session intensity 6.9 AU lower and 13.9 AU lower for a 10% maturity shift. Both 5% and 10% changes in maturity most likely resulted in higher countermovement jump, with likely to very likely differences observed for RSI and ABS. Maturity substantially influences neuromuscular performance over the season. Therefore, maturity-specific load prescription may prevent significant within age-group differences in accumulated load, possibly reducing injury risk and/or burnout

Cultivating sustainable consumption: The role of harmonious cultural values and pro-environmental self-identity

This paper investigates the connections between harmonious cultural values, pro-environmental self-identity and consumers’ sustainable consumption behaviours spanning acquisition, usage and disposal. It evaluates the relevance of Chinese cultural values that purport harmony between humans, nature and society i.e. man-nature orientation and horizontal/vertical dimensions of individualism-collectivism. The results from the online survey with 503 urbanised Chinese reveal these values disparately influence this consumption. Despite the limited direct behavioural effect of these harmonious values, pro-environmental self-identity plays an important role in mediating their indirect effects on the five behaviours. This paper therefore extends theorisation of the values-identity-behaviour relationship from a cultural-values orientation perspective. It offers new insights to understand urbanised Chinese consumers' sustainable consumption behaviours

Feasibility of OpenPose markerless motion analysis in a real athletics competition

This study tested the performance of OpenPose on footage collected by two cameras at 200 Hz from a real-life competitive setting by comparing it with manually analyzed data in SIMI motion. The same take-off recording from the men's Long Jump finals at the 2017 World Athletics Championships was used for both approaches (markerless and manual) to reconstruct the 3D coordinates from each of the camera's 2D coordinates. Joint angle and Centre of Mass (COM) variables during the final step and take-off phase of the jump were determined. Coefficients of Multiple Determinations (CMD) for joint angle waveforms showed large variation between athletes with the knee angle values typically being higher (take-off leg: 0.727 ± 0.242; swing leg: 0.729 ± 0.190) than those for hip (take-off leg: 0.388 ± 0.193; swing leg: 0.370 ± 0.227) and ankle angle (take-off leg: 0.247 ± 0.172; swing leg: 0.155 ± 0.228). COM data also showed considerable variation between athletes and parameters, with position (0.600 ± 0.322) and projection angle (0.658 ± 0.273) waveforms generally showing better agreement than COM velocity (0.217 ± 0.241). Agreement for discrete data was generally poor with high random error for joint kinematics and COM parameters at take-off and an average ICC across variables of 0.17. The poor agreement statistics and a range of unrealistic values returned by the pose estimation underline that OpenPose is not suitable for in-competition performance analysis in events such as the long jump, something that manual analysis still achieves with high levels of accuracy and reliability

Understanding the Psychological Determinants of Buy-Now-Pay-Later (BNPL) in the UK: A User Perspective

Purpose: This study explores the psychological determinants of buy-now-pay-later use in the UK and reviews the efficacy of existing payment constructs. Design/methodology/approach: 533 BNPL users engaged in story stem completion. Template analysis was used, supported by the identification of four BNPL sentiment groups to enable comparison. Findings: Whilst positive attitudes towards BNPL dominate, other psychological determinants are apparent to a varied extent. Psychological distance and ownership of borrowed money are redolent, transparency and transaction convenience are less appreciable. BNPL users understand temporality beyond its current conceptualizations. Some users construe BNPL as a ‘savings’ product, hence payment format conceptualizations may be erroneous. Those with a positive sentiment foreground BNPL’s consumption and budget management benefits. However, the potential for unintended consequences are manifest across all users. Research implications: The potentially unwanted consequences, or dark side, of BNPL use in the UK are highlighted. The specified constructs, whilst helpful, do not particularize the complex interconnected nature of the psychological determinants of BNPL use. Improved conceptualization offering richness and clarity is needed – temporality specifically requires consideration. Practical implications: Users’ sophistication and misunderstanding are both evident, necessitating fuller conversations among various stakeholders – including, providers, policymakers, consumers, and advocacy groups

Understanding retail supply chain during COVID-19: A systematic review

Purpose– The aim of this paper is to identify the themes that emerged from retail supply chain (RSC) literature during the COVID-19 pandemic that inform future mitigation and recovery strategies. Design/methodology/approach– This study analyses contributions in the RSC literature using four databases: Emerald, Elsevier (Science Direct), Wiley, and Taylor & Francis. The systematic review approach resulted in identifying 74 articles covering 2020 to 2022. Findings– Four themes emerged from RSC literature on COVID-19. The first theme highlighted factors that exacerbated the effects of COVID-19 pandemic on the RSC. The second theme focused on the types of disruptions that occurred in the RSC during the pandemic. The third theme demonstrated the recovery strategies used to reduce the impact of COVID-19 on the RSC. The fourth theme identified proposed mitigation strategies for the RSC post COVID-19 outbreak. Practical implications–The study provides a deeper understanding of how retail supply chain managers could successfully reduce the effects of the COVID-19 pandemic by dealing with interruptions. Based on the reviewed studies and the four themes that evolved from RSC literature on COVID-19 throughout 2020-2022, eleven key RSC strategies and lessons have been recommended to decision makers in the retail industry. Originality/value– This is the first study to identify the themes that emerged from RSC literature during the COVID-19 pandemic to inform future mitigation and recovery strategies. The resulting themes add to the existing body of knowledge and established the need for further research into other sectors that might be affected by future pandemics. Keywords: Retail Supply Chain, Supply Chain Disruptions, Mitigation Strategies, Recovery Strategies, Covid-19, Systematic Review

Local Authority Waste Management Strategies, the Circular Economy and the Generation of Energy from Waste in England

The purpose of this article is to examine the approach to waste management of local authorities in England, to investigate their strategic objectives, and to ascertain to what extent sustainability and circular economy practices are in evidence in this context. A qualitative, inductive research method is used, based on an examination of secondary documentation in three local authorities in England in Birmingham, Bristol and Newcastle upon Tyne. The findings reveal considerable common ground within the three authorities – the importance of consumption across society in contributing to the generation of waste, the need for behavioural change, a focus on reducing waste (particularly food waste), maximising recycling and re-use, reducing carbon dioxide emissions, and actively involving the local community and businesses. The case studies also evidence clear support for moving towards a more circular economy, but a number of key challenges were identified whilst initiatives to increase “waste to energy” face a number of potential hurdles. These include the generation of pollution and particulates by waste to energy plants, the destruction of useful materials, and the potential to disincentivise more sustainable waste management solutions. The article makes a small contribution to an existing gap in the academic literature and it is hoped these cases may act as a template for other research studies that could provide comparisons and contrasts in other local authority contexts

Advanced Analytics and Data Management in the Procurement Function: An Aviation Industry Case Study

The company’s strategic procurement function makes a significant contribution to overall corporate success, and yet remains under-researched in terms of digitalisation and digital maturity. This research adopts an inductive case study approach, using qualitative data from in-depth interviews with industry practitioners to develop and apply a digital maturity model for the deployment of strategic procurement analytics. The case study company is a multinational aerospace corporation with almost 150,000 employees worldwide. The research presents a snapshot of the digital maturity of the strategic procurement function of this global aircraft manufacturer and finds that the current exploitation of analytics remains constrained by a range of factors, including the need for close compliance with regulatory norms. Thematic analysis of the interview material provides the basis for the development of the maturity model, which — although geared to a specific industry context - is nevertheless of relevance in other business environments. The research thus contributes to the existing literature in this field, and will also be of interest to procurement professionals. However, the research clearly has its limitations, not least in that it is based on just one industry case, and cross-industry generalisations from the findings must therefore be treated with caution

Positioning action research as a critical means of understanding coaching: considerations from the field

This paper shines light upon the methodological value of action research as a critical means of studying coaching practice. Described as an opportunity for bridging the gap between practice and research, the application of action research to sports coaching aims to explicitly and intentionally advance practice. However, far from the enduring depictions of action research as a linear cyclical process, contemporary action research has begun to appreciate its ambiguity; much like the problematic nature of sports coaching itself. Despite this ambiguity, we contend that action research can better harness the messy realities and complexities that coaches encounter within their everyday practice. Through the provision of critical reflections the overarching aim of the paper was not only to make the case for action research as a means of cultivating critical scholarship in sports coaching but to go further, problematising some complex realities of life as an action researcher

Towards a conceptual framework for the prevention of gambling-related harms: Findings from a scoping review

The global gambling sector has grown significantly over recent years due to liberal deregulation and digital transformation. Likewise, concerns around gambling-related harms—experienced by individuals, their families, their local communities or societies—have also developed, with growing calls that they should be addressed by a public health approach. A public health approach towards gambling-related harms requires a multifaceted strategy, comprising initiatives promoting health protection, harm minimization and health surveillance across different strata of society. However, there is little research exploring how a public health approach to gambling-related harms can learn from similar approaches to other potentially harmful but legal sectors such as the alcohol sector, the tobacco sector, and the high in fat, salt and sugar product sector. Therefore, this paper presents a conceptual framework that was developed following a scoping review of public health approaches towards the above sectors. Specifically, we synthesize strategies from each sector to develop an overarching set of public health goals and strategies which—when interlinked and incorporated with a socio-ecological model—can be deployed by a range of stakeholders, including academics and treatment providers, to minimise gambling-related harms. We demonstrate the significance of the conceptual framework by highlighting its use in mapping initiatives as well as unifying stakeholders towards the minimization of gambling-related harms, and the protection of communities and societies alike
