Summary: This study analyzes the performances of professional dart players in the absence of spectators, the presence of real crowds, and the presence of simulated crowds. The findings suggest that the presence of others negatively impacts coordination-based accuracy tasks. Therefore, it is hypothesized that the performance of elite darts players deteriorates in the presence of a real audience compared to no audience and simulated audience.

Summary: This study analyzed the performance of dominant and non-dominant limbs in professional futsal matches, finding that players tend to use their dominant limb more frequently and with higher accuracy. Except for pivots showing similar shooting accuracy with both limbs, players from all positions generally displayed higher accuracy rates when using their dominant limb for receiving, passing, and shooting a ball, regardless of opponent quality.

Summary: This research uses online chess tournaments during the COVID-19 pandemic to study the impact of remote work policies on cognitive performance. The study finds a significant decrease in performance for individuals competing remotely compared to face-to-face competitions, but this effect diminishes over time, suggesting an adaptation to the new remote setting.

Summary: The research demonstrated that the nonverbal behavior of professional darts players before performance can give valid information to observers about their subsequent performance tendencies. This suggests that highly skilled individuals may display nonverbal cues that can be picked up by observers to make inferences about their likely performance.

Summary: Traders exhibit significant heterogeneity in performance and learning ability in an ambiguous environment like the cryptocurrency market. They do not learn to gradually increase returns but can improve their ability to realize profits to survive ambiguity. Adaptation increases as traders progress in their career, with evidence supporting the gambler's fallacy. Learning in ambiguous environments is limited, primarily enabling traders to survive.

Summary: The aim of this study was to monitor the activation during a neutral situation imagery (NSI) and a pressure situation imagery (PSI), based on the analysis of heart rate, brain waves and subjective ratings in athletes. Results showed that both NSI and PSI increased heart rate and had different effects on gamma wave activity and entropy. Significant differences were found in subjective ratings only in PSI.

Summary: The purpose of this study was to assess the effectiveness of hand motion analysis, using both conventional and new motion metrics, in distinguishing the skill levels of operators performing central venous access and liver biopsy procedures. The results revealed that experts outperformed trainees in all metrics for central venous access procedures. Furthermore, experts demonstrated shorter path lengths, fewer translational and rotational movements, and less time in liver biopsy procedures compared to trainees. Therefore, hand motion analysis utilizing translational and rotational movements proved to be more effective in differentiating skill levels and improvement with training than the conventional metric of path length.

Summary: The heating performance of solar chimney under different modes was investigated in this study. The impacts of various design factors on temperature rise and airflow rate were analyzed numerically and empirically. The results showed that the design factors had exponential relationships with temperature rise and airflow rate. The study also provided recommendations on the application of different heating modes based on different climates and scenarios.

Summary: The study found that induced anisometropia significantly reduced the performance of ophthalmic surgery in a simulated environment, which was associated with a deterioration in stereoacuity. Therefore, assessing stereoacuity may be included as a regular part of the screening procedure for ophthalmic trainee residents.

Summary: Compromised cognitive performances have been widely reported under hot and humid environments due to frequent and intense extreme climate events. In this study, the cognitive performance of 14 male participants was evaluated under different levels of hot-humid exposure. The results showed that skin temperature increased during the exposures, and there was a negative relationship between accuracy and response time. Additionally, a relationship between skin temperature and relative cognitive performance was identified.

Summary: Continuing professional development (CPD) is crucial for teachers to maintain and update their knowledge and skills in best practices. Research on physical education CPD (PE-CPD) has shown that current provisions are ineffective, but online programs could offer a more accessible and effective alternative. Teachers express motivation for online PE-CPD, yet remain cautious due to concerns about lack of community support. Recommendations include evidence-based, interactive programs that focus on pedagogical content knowledge and facilitate communities of practice.

Summary: During search and rescue missions, effective memorization and retrieval of critical spatial information is crucial for firefighters to reduce risks and increase efficiency. Different formats of wayfinding information have been found to impact search and rescue performance in various ways, but there is limited understanding of firefighters' cognitive processes related to these formats. A Virtual Reality (VR) experiment was conducted to evaluate firefighters' performance and cognitive characteristics, revealing that cognitive load and fatigue levels were lower and wayfinding performance was better when firefighters made more effective cognitive decisions at critical waypoints. On the other hand, using landmark information resulted in consistently high cognitive load and increased mental fatigue.

Summary: We investigate the occurrence of momentum shifts in football matches by modeling minute-by-minute in-game statistics using hidden Markov models and copulas. Our findings suggest that there are change points in the dynamics of football matches, indicating different levels of control exhibited by teams. This research has implications for managers, bookmakers, and sports fans in understanding team tactics and factors influencing momentum shifts.

Summary: The study presents a penalized likelihood approach for automated variable selection in hidden Markov models (HMMs), considering a large number of potentially correlated covariates. By quadratically approximating the non-differentiable penalty, the likelihood can be maximized numerically. The feasibility of the approach is assessed through simulation experiments and applied to investigate the 'hot shoe' effect in football penalty takers.

Summary: Continuous-time state-space models (SSMs) are flexible tools for analyzing irregularly sampled sequential observations. This study provides a general continuous-time SSM framework that allows for nonlinear and non-Gaussian observation and state processes. Statistical inference is conducted using maximum approximate likelihood estimation, and efficient algorithms for parameter estimation and state decoding are applied using the reframed SSM as a continuous-time hidden Markov model.

Summary: Based on data from German professional soccer, players may choose to conserve resources in a current contest to allocate more in a subsequent contest, depending on the degree of heterogeneity in each match. The decision-making of players facing the risk of suspension is influenced by the level of heterogeneity in the current and upcoming matches, affecting their likelihood of participation and behavior.

Summary: It is still uncertain to what extent bettors adjust their prior assumptions about the strength and form of competing teams during a live match. This is not only interesting from a psychological perspective, but also in terms of pricing live odds based on both outcome probabilities and bettors' behavior. Using state-space models, the study analyzes high-frequency data on stakes placed during the match and finds that live-betting stakes are influenced by both pre-game perceptions and in-game strengths measured by the Valuing Actions by Estimating Probabilities (VAEP) approach. These effects also vary throughout the match.

Summary: Previous literature suggests that inefficiencies are common in betting markets, but most studies lack data and fail to consider the persistence of biases. This article uses simulation-based analyses and empirical research on football betting markets to show that inefficiencies may occur in single seasons, but they are not persistent or systematic across leagues.
