Football performance results from the dynamic interaction between physical, tactical, technical, and psychological dimensions—each of which also influences player well-being, recovery, and readiness. However, integrated monitoring approaches remain scarce, particularly in youth and sub-elite contexts. This systematic review screened 341 records from PubMed, Scopus, and Web of Science, with 46 studies meeting the inclusion criteria (n = 1763 players; age range: 13.2–28.7 years). Physical external load was reported in 44 studies using GPS-derived metrics such as total distance and high-speed running, while internal load was examined in 36 studies through session-RPE (rate of perceived exertion × duration), heart rate zones, training impulse (TRIMP), and Player Load (PL). A total of 22 studies included well-being indicators capturing fatigue, sleep quality, stress levels, and muscle soreness, through tools such as the Hooper Index (HI), the Total Quality Recovery (TQR) scale, and various Likert-type or composite wellness scores. Tactical behaviours (n = 15) were derived from positional tracking systems, while technical performance (n = 7) was assessed using metrics like pass accuracy and expected goals, typically obtained from Wyscout^® or TRACAB^® (a multi-camera optical tracking system). Only five studies employed multivariate models to examine interactions between performance domains or to predict well-being outcomes. Most remained observational, relying on descriptive analyses and examining each domain in isolation. These findings reveal a fragmented approach to player monitoring and a lack of conceptual integration between physical, psychological, tactical, and technical indicators. Future research should prioritise multidimensional, standardised monitoring frameworks that combine contextual, psychophysiological, and performance data to improve applied decision-making and support player health, particularly in sub-elite and youth populations.

The aim of this study was to investigate whether juror characteristics, namely, age, attitudes surrounding coercive control and psychopathic personality traits (PPT), can influence Guilty or Not Guilty verdicts in a developed coercive control trial. One hundred and thirty-five participants (N = 135) completed an online survey consisting of elements of a mock coercive control trial and three questionnaires: the Coercive Control subsection of the Modern Adolescent Dating Violence Attitudes (MADVA (CC)) Scale, the Psychopathic Personality Traits Scale—Revised (PPTS-R) and the Juror Decision Scale (JDS). The results of the analysis demonstrated significant positive correlations between MADVA (CC) scores and all four subscales of the PPTS-R, highlighting the relationship between psychopathy traits and coercive control attitudes. Binary logistic regression findings showed that higher scores on the MADVA (CC) Scale were the only significant predictor of returning a Not Guilty verdict. Those who also returned a Not Guilty verdict had more accepting controlling behaviour attitudes, scored higher for defendant believability and were less confident in their overall decision. Findings from the current study highlight the significance of attitudes in a juror decision-making context. The significance of attitudes may also be applicable to police officers and other agencies within the criminal justice system. Additional efforts need to be made regarding the identification of coercive control tactics, and training programmes should be implemented within the police to increase identification of these behaviours in order and to improve case progression. This may increase the likelihood of a jury being required in these cases. Furthermore, Not Guilty verdicts were given with significantly less confidence than Guilty verdicts, although they have the same influence at trial. More research needs to be carried out to explore the development and maintenance of accepting attitudes towards coercive control, and there is a need for better education regarding coercive control to attempt to tackle harmful attitudes towards it and aim for fairer trials.

Background: Despite concerted research efforts, the collection of domestic waste remains poorly understood in terms of financial and environmental cost drivers. Detailed studies of specific systems, yielding limited broader understanding, remain the norm. Methods: This study presents flexible and generally applicable models for domestic waste transport logistics, based on economic cost and environmental impact calculations. Results: The calculations reveal key sensitivities by highlighting the most important cost and environmental drivers and linking these to key factors relating to the deployment of staff and collection vehicles, behaviour of consumers, and others. Conclusions: This study demonstrates these elements in a Norwegian context, showing that the models can inform tactical and operational decision-making for the logistics of domestic waste collection, and inform policy development in the area.

Background: Leveraging healthcare technology improves human development and well-being. However, adoption is frequently delayed by behavioural and psychological barriers, such as perceived usefulness, trust, and organisational readiness. This review examines the suitability of the Unified Theory of Acceptance and Use of Technology (UTAUT) and the Technology Acceptance Model (TAM) frameworks in healthcare settings, focusing on behavioural, educational, and psychological factors that influence technology adoption. Methods: A total of 20 peer-reviewed articles from 2019 to 2024 were examined. Results: The review identified significant organisational and psychological obstacles, including a lack of trust, inadequate training, and organisational support. While the UTAUT provided a more comprehensive viewpoint, it needed to be modified to include context-specific factors, including trust, facilitating circumstances, and educational interventions. Meanwhile, the TAM’s emphasis on perceived usefulness and ease of use was shown to be insufficient for dealing with complex healthcare situations. Conclusions: Interventions targeting stakeholders’ organisational and psychological preparation and educational strategies are essential to overcoming resistance and enhancing trust. Future research should look into integrative frameworks incorporating behavioural, psychological, and instructional tactics to improve the use of technology in healthcare. Full article

According to Young Minds, ‘everyone gets angry sometimes’. Their website offers a number of de-escalating strategies, including staying calm, managing responses, and setting limits to help young people who most deem resistive. Yet, Young Minds are not alone because such logical advice is ubiquitous in the literature about challenging behaviour despite the fact that in our experience when faced with high states of arousal, most young people tend to act first and deal with the consequences later. It is not that they are stupid or non-caring, but they are human, capable of great feats as well as stupidity. The same is true for any claims that solution focused (SF) conversations can put right the several decades of psychological theory suggesting resistance requires logic and better cognition. By giving the correct thinking skills, young people will walk away from risk, avoid physical confrontation, handle challenging situations like logical thinkers, and generally discount that the process of growing up is part of the challenge. It is with this in mind that over recent years in our current SF practice (with staff group supervision), we have examined the concept of ‘resistance’ and how it can be put to use as a process of collaboration. To do this, we have revisited SF theory that preoccupied many of its pioneers during the 1980s and 1990s and attempted to make it useful for the early 2020s for professionals having conversations with young people, who, in traditional models, are labelled challenging. We want to introduce key differences of solution focused practice and how our research started to formulate a 6D-SF model (details, dynamics, dimensions, dispositions, dislocations, descriptions) for contemplating how groups of professionals relate to each other and are triggered by challenging behaviour. We do not claim to have proof, logic, or exactness on our side, but we are happy to suggest how our resistance mirrors what many of the staff teams feel and describe when working through their work.

This study aimed to explore how positional performance varies across different youth age groups and during matches in football competitions. The study encompassed 160 male outfield youth football players (n = 80, under-13, U13; n = 80, under-15, U15) who belonged to the starting line-up and played the entire first half of each match. The players’ positional data were gathered through the global positional system for each of the eight matches performed by each age group. The frequency of near-in-phase synchronization based on speed displacements, spatial exploration index, and the distance to the nearest teammate and opponent were used as variables. Additionally, each match half was segmented into three equal parts to assess changes over time and used as a period factor along with age group. The results indicated that U13 players showed a significant decrease (from small to large ES) in synchronization speed and spatial exploration index throughout the first half of the match, along with a decrease in the distance to the nearest opponent. In contrast, U15 players exhibited most changes during the third segment of the half, with a decrease in speed synchronization and spatial exploration, but an increase in the distance and regularity to the nearest opponent. Comparing both age groups revealed significant differences in speed synchronization across the entire half of the match and within each segmented period (from small to large ES), with U13 consistently showing higher values. The study highlights that long durations in 11 vs. 11 matches might not provide an appropriate learning environment in the U13 age group. Conversely, the U15 group displayed better capacity for tactical adjustments over time, suggesting a higher level of tactical maturity. Overall, these findings emphasize the importance of adapting youth football training and competition structures to the developmental needs and capabilities of different age groups to optimize learning and performance outcomes.

This article proposes the novel understanding of the Egyptian Muslim Brotherhood as a sect, going against the grain of the existing literature, which posits it as a political group, a social movement, or a religious movement (or some combination of all of the above). The sectarianisation occurs within the group via ideological build-up, organisational tactics, and internal socialisation of behaviour. The group is also a sect by constituting its unique identity in opposition to external actors. To make the argument, the analysis draws on the statements of key figures within the movement’s history, such as its founder Hasan al-Banna, as well as a range of interviews with current and ex-members. My argument has two main consequences for our understanding of sectarianism in general and the Brotherhood in particular. First, sectarianism is a process of sectarianisation that operates beyond the state and at lower levels, such as groups and individuals. Second, the Brotherhood is not a mere victim of the sectarianising practices of the state. Its sectarianisation is partly of its own making. Full article

Sports teams aim to understand the tactical behaviour of their opposition to gain a competitive advantage. Prior research of tactical behaviour in team sports has predominantly focused on the relationship between key performance indicators and match outcomes. However, key performance indicators fail to capture the patterns of ball movement deployed by teams, which provide deeper insight into a team’s playing style. The purpose of this study was to quantify existing ball movement strategies in Australian-rules Football (AF) using detailed descriptions of possession types from 396 matches of the 2019 season. Ball movement patterns were measured by social network analysis for each team during offensive phases of play. K-means clustering identified four unique offensive strategies. The most successful offensive strategy, defined by the number of matches won (83/396), achieved a win/loss ratio of 1.69 and was characterised by low ball movement predictability, low reliance on well-connected athletes, and a high number of passes. This study’s insights into offensive strategy are instructional to AF coaches and high-performance support staff. The outcomes of this study can be used to support the design of tactical training and inform match-day decisions surrounding optimal offensive strategies. Full article

The ability to overcome an opposition in team sports is reliant upon an understanding of the tactical behaviour of the opposing team members. Recent research is limited to a performance analysts’ own playing team members, as the required opposing team athletes’ geolocation (GPS) data are unavailable. However, in professional Australian rules Football (AF), animations of athlete GPS data from all teams are commercially available. The purpose of this technical study was to obtain the on-field location of AF athletes from animations of the 2019 Australian Football League season to enable the examination of the tactical behaviour of any team. The pre-trained object detection model YOLOv4 was fine-tuned to detect players, and a custom convolutional neural network was trained to track numbers in the animations. The object detection and the athlete tracking achieved an accuracy of 0.94 and 0.98, respectively. Subsequent scaling and translation coefficients were determined through solving an optimisation problem to transform the pixel coordinate positions of a tracked player number to field-relative Cartesian coordinates. The derived equations achieved an average Euclidean distance from the athletes’ raw GPS data of 2.63 m. The proposed athlete detection and tracking approach is a novel methodology to obtain the on-field positions of AF athletes in the absence of direct measures, which may be used for the analysis of opposition collective team behaviour and in the development of interactive play sketching AF tools.

Large-scale crowd phenomena are complex to model because the behaviour of pedestrians needs to be described at both strategic, tactical, and operational levels and is impacted by the density of the crowd. Microscopic models manage to mimic the dynamics at low densities, whereas mesoscopic models achieve better performances in dense situations. This paper proposes and evaluates a novel agent-based model to enable agents to dynamically change their operational model based on local density. The ability to combine microscopic and mesoscopic models for multi-scale simulation is studied through a use case of pedestrians at the Festival of Lights, Lyon, France. Pedestrian outflow data are extracted from video recordings of exiting crowds at the festival. The hybrid model is calibrated and validated using a genetic algorithm that optimises the match between simulated and observed outflow data. Additionally, a local sensitivity analysis is then conducted to identify the most sensitive parameters in the model. Finally, the performance of the hybrid model is compared to different models in terms of density map and computation time. The results demonstrate that the hybrid model has the capacity to effectively simulate pedestrians across varied density scenarios while optimising computational performance compared to other models.

This article explores the incongruous results of creativity and risk-taking within art practice and everyday life as encountered through the photographic image. The impetus for this study was a humorous experience that took place during health and safety training that raised questions about the role of humour within everyday life. Research was conducted into two forms of visual media, including pamphlets and guides from the British Safety Council (BSC) archives and viral images that demonstrate accidents (tagged with an ‘epic fail’ hashtag). This led to a practice-based approach to research involving the production of photographic works for an exhibition that tested the role of risk-taking and improvisation within the creative process. This article uses humour theory including superiority, incongruity and relief theory in relation to Louise Peacock’s model for the analysis of slapstick, to analyse these different types of photographs and draws comparisons between the risk-taking creative behaviours of both employees and artists. These creative approaches are considered in relation to Michel de Certeau’s notion of tactics within everyday life. Ordinary thinking and improvisational tactics are present within both art and work, and improvisation heightens the potential for risk-taking. This may lead to incongruities represented through a photograph which can impact the viewer’s engagement through humour, fascination or self-reflexivity. It is proposed that the viewer response to images containing risk is made up of a balance between an embodied understanding of the dangers and an awareness of the artifice, which can shift depending on the conditions of the photograph’s production and display. The peculiarities of the photograph are seen as conducive to a humour response because of the photograph’s ambiguous relationship with the reality that it represents. Full article

Energy retrofit solutions that concern a building’s roof structure play a significant role in the enhancement of a building’s thermal behaviour. This study investigates the integration of phase change materials (PCMs) with cool coatings (CCs) or thermochromic coatings (TCCs), namely, a PCM roof, a PCM-CC roof, and a PCM-TCC roof, as alternative and novel tactics for the simultaneous control of solar heat transfer and solar heat reflection. An energy simulation analysis with the DesignBuilder tool is conducted for a one-story residence and the climatic conditions of Athens. The simulation results indicate that, compared to the existing concrete roof construction, the PCM roof, PCM-CC, and PCM-TCC roof systems demonstrate energy savings that reach up to 13.55%, 16.04%, and 21.70%, respectively. The systematic analysis reveals that the increase in PCM’s thickness leads to an increase in the total electricity savings of the buildings, but in the case of PCM-CC and PCM-TCC roof systems, they merely effect the cooling thermal loads. The mean phase transition temperature that favours the cumulative electricity savings is 28 °C in the case of PCM and PCM-TCC roof systems and 35 °C in the case of PCM-CC roof systems. The methodology of this study allows the design of efficient, integrated roof systems with advanced thermal and optical properties as energy retrofit solutions for Mediterranean climatic conditions.

One of the great business institutions of the modern era is the BBC which is now 100 years old. The authors explored letters and memoranda in the BBC’s Written Archives at Caversham, which revealed much about the business tactics of those in charge of the BBC during the pre-Second World War era, and how they used the power of their monopoly to their own ends. A new market of broadcasting magazines sprang up around the radio broadcasts, creating an inter-dependency between the two media. The BBC soon launched its own magazines, and from then on, the BBC’s interactions with the press media were complex, reflecting an uncomfortable blend of symbiosis and threat. Episodes between the press owners and the BBC have been uncovered, about which there has been little previous investigation, and unexpected patterns of behaviour have emerged. This archival research, using narrative history, is based upon original letters, memoranda and handwritten messages that were archived for posterity, and which report upon the actual thoughts and views of those involved at the time, revealing unexpected intrigue and machinations.

With the threat of the climate emergency intensifying and limited time left to reduce irreversible consequences, the need to consider how natural resources are excavated and managed from cradle to grave intensifies. This positions the circular economy (CE) as being highly relevant, particularly for the fashion industry, which is criticised for encouraging continued frequent and impulsive consumption of inexpensive garments with limited longevity. Advancing the circular fashion economy (CFE) has received little attention. Limited research to date has found that consumers have not been socialised to consider fashion acquisition as a collaborative or sharing activity, revealing an established attitude–behaviour gap that prohibits the advancement of the sustainable-fashion agenda. Primarily, fashion is imbued with social and emotional capital, as experienced with the dominant social paradigm (DSP) of fast fashion. This paper argues that similar tactics can be adopted for sustainable fashion practices through the CFE by exemplifying a case study of a fashion-renting platform, “Wardrobe,” that enables consumers to rent fashion owned by influencers and celebrities. In doing so, the paper makes four contributions to the knowledge: Firstly, in developing a conceptual framework from research examining fashion, sustainable fashion, and the CFE, the paper illuminates how fashion marketing emphasises social and celebrity capital to appeal to consumer emotions, encouraging frequent impulsive consumption, and how this can be transferred to the CFE. Secondly, the DSP is contextualised alongside the theory of disruptive innovation to understand how social norms of fashion consumption can be disrupted. Thirdly, although there is an emerging literature stream examining the CE and CFE, this focuses more on consumer practice and behaviours, and little attention has been paid to how the CFE can be marketed to engage with consumers. Fourthly, this paper illuminates how similar marketing tactics used by fast fashion can be exploited to advance the CFE. Full article

Background: Female sex workers (FSWs) are at a higher risk of contracting and transmitting HIV and other sexually transmitted infections (STIs). We aimed to explore the sexual behaviour, knowledge and attitudes towards STIs, barriers, support and intervention for STI screening. Methods: In this community-based, concurrent quantitative–qualitative, exploratory mixed-methods study, we administered 87 semi-structured quantitative and six in-depth interviews to purposively select FSWs in Gulu City, Uganda. The qualitative methodology was based on descriptive phenomenology. Results: The quantitative study included 87 FSWs, with a median age of 28 years. Overall, 87.4% (n = 76) participants reported condom use during their last sexual encounter. Eighty-three (95.4%) participants were aware of their HIV status, with 6% (n = 5) reporting being HIV-positive. Seventy-six (87.4%) participants reported contracting at least one STI during sex work. In addition, 66.7% (n = 58) of the participants reported being screened for STIs in the past three months, with vulvovaginal candidiasis (55.3%, n = 42) and syphilis (32.9%, n = 25) being the most common STIs. However, only 2.3% (n = 2) of the participants reported current STIs symptoms. In the qualitative study, the main themes encompassed sexual behaviour, including condom-use negotiation strategies and challenges, as well as screening facilitators and barriers. Condom-use negotiation tactics involved leveraging health-risk information, increased charges for unprotected sex, and outright refusal. Complex challenges included limited agency in promoting safe sex due to economic reliance, vulnerability to violence, and difficulties in controlling the sexual environment. Facilitators for regular screening included social influences, emotional relief, established testing habits, and accessible clinics, while barriers encompassed cost, stigma, doubts about test accuracy, and inconvenient clinic hours. Conclusions: FSWs face significant vulnerabilities in Gulu City, Uganda, regarding STIs. While encouraging trends such as high HIV awareness and condom usage were observed, persistent challenges in STI screening, negotiation of safe sex practices, and access to prevention and treatment remain evident. To address these concerns, targeted interventions should be developed to enhance STI screening accessibility, empower sex workers with effective negotiation skills, and provide comprehensive support for STI prevention and treatment, thereby contributing to improved overall sexual health and well-being among this marginalized population.
