Summary: This study integrates cognitive strategies, task properties, and social influence processes using a dynamical system model to investigate the impact of social learners on collective decision outcomes in a binary choice. The research predicts that the proportion of social learners exceeding a critical threshold can lead to a bistable state where the majority may end up favoring either the higher- or lower-merit option, depending on fluctuations and initial conditions. The critical threshold is determined by the conformity response function and the relative merits of the options.

Summary: This study compares the performance of under-18 association football players when manipulating the number of teammates and opponents during training. The results show that adding teammates increases longitudinal synchronization and decreases the distance to the nearest teammate, while reducing running distance in the defensive phase. Attacking with numerical inferiority increases variability in the distance to the nearest teammate and decreases physical demands. Defending, especially in high-inferiority, increases total running distance and decreases the distance to the nearest teammate.

Summary: In this article, the dynamics of marking in football matches are studied by analyzing the trajectories of players on the field. A temporal bipartite network of proximity is constructed to describe the dynamics. The study reveals a scaling law for the heterogeneity parameter of the networks, indicating the emergence of complexity in the system. Additionally, a simple model is proposed to simulate the players' motion and it proves to be useful in elucidating the underlying mechanisms responsible for the observed phenomena.

Summary: This study reviewed the patterns of collective behavior and social movements and examined the psychosocial factors that explain participation in them. The findings suggest that participation in collective behavior and social movements is associated with intergroup conflict, positive attitudes, collective identity, emotions, and more. Participation in successful collective behavior and social movements can lead to positive changes, but also negative effects. The importance of systematic studies and culturally diverse research on collective behavior and social movements is emphasized.

Summary: The study of collective behavior is crucial in understanding how group actions and characteristics emerge from individual information sharing. In the digital age and with the rise of social media, social systems are undergoing rapid changes, posing challenges for scientific progress, democracy, and addressing global crises. It is argued that collective behavior research should become a crisis discipline, providing actionable insights for policymakers to steward social systems.

Summary: Research has found that the complexity of solar irradiance time series can be effectively analyzed using Kolmogorov complexity and Aksentijevic-Gibson complexity, providing insights into both global/long-term structures and local/short-term fluctuations. The study also identifies a potential weekly periodicity related to environmental factors and human activity. These findings suggest that Aksentijevic-Gibson complexity could be a valuable tool not only for studying solar irradiation time series, but also for other types of geophysical data.

Summary: This study formalizes and combines feminist theoretical approaches into a game-theoretic model to understand women's collective action to change gendered social norms. It finds that social norms create a social dilemma where promoting altruism among women can overcome the dilemma. Other methods, such as discouraging women from tolerating domestic violence or imposing additional punishment on men, may not be effective and could even backfire.

Summary: Understanding the test-retest reliability of biomechanical variables during cycling is important for assessing training effects. This study quantified the reliability of these variables in short-term maximal cycling. The results showed that most of the biomechanical variables had moderate to excellent reliability, but some variables had lower reliability, suggesting caution is needed when using them to evaluate biomechanical changes.

Summary: People are often encouraged to see life as a journey of fulfilling their potential. Traditionally, potential is seen as coming from biology and fulfillment from culture. However, this static view raises the question of what comes next after one's potential is fulfilled. An alternate perspective suggests that potential and fulfillment come from responsive openness to varied experiences, growing knowledge through interactive relationships.

Summary: This study aimed to characterize the passing patterns that support collective tactical behavior in football players of different ages (U15, U17, and U19) in different field zones. The results showed that long and medium passes were more commonly used in areas close to the goals, while short passes were more commonly used in the middle area of the field, regardless of age. Older players (U17 and U19) tended to pass to more distant players in medium and long passes. These findings can help coaches design suitable training activities based on players' ages and adjust for field space and numerical relationships, facilitating a better transition from training to competition.

Summary: From an ecological dynamics perspective, the manipulation of task constraints can allow for functional movement variability of participants, leading to enhanced performance. The constraints-led approach (CLA) induces functional movement variability in practice designs, supporting athletes in meeting task constraints and achieving desired outcomes. In a study of young male volleyball players, the CLA practice group showed significantly higher success rates in attacking actions compared to the traditional approach (TA) group after a 6-week intervention. Binomial logistic regression analysis revealed that lateral and longitudinal deviations of the participants' center of mass were the main predictors of successful attacking outcomes.
