    Abstract This study aims to utilize data from the Programme for International Student Assessment (PISA), 2018, conducted in four provinces and cities in China, to investigate the impact of social support on the resilience of disadvantaged students. It specifically focuses on the chain-mediated effects of school belonging and emotional experiences. To achieve this, the study selected 2997 disadvantaged students as participants and employed path analysis to examine the mediating effects. The results indicate that teacher support, parental support, school belonging, and positive emotional experiences significantly positively influence the resilience of disadvantaged students, while fear of failure significantly negatively affects resilience. Additionally, teacher and parental support indirectly impact the resilience of disadvantaged students through the chain-mediated effects of school belonging and positive emotional experiences. Similarly, teacher and parental support also influence the resilience of disadvantaged students through the chain-mediated effects of school belonging and fear of failure. To enhance the resilience development of disadvantaged students, it is recommended that teachers and parents provide active attention and support to these students. Simultaneously, there should be increased focus on the psychological well-being of disadvantaged students by strengthening their mental health education.

    Abstract Nash equilibrium is a significant solution concept representing the optimal strategy in an uncooperative multiagent system. This study presents two deep reinforcement learning (DRL) algorithms for solving the Nash equilibrium of differential games. Both algorithms are built upon the distributed distributional deep deterministic policy gradient (D4PG) algorithm, which is a one-sided learning method. We modified it to a two-sided adversarial learning method. The first is D4PG for games (D4P2G), which directly applies an adversarial play framework based on the D4PG. A simultaneous policy gradient descent (SPGD) method is employed to optimize the policies of the players with conflicting objectives. The second is the distributional deep deterministic symplectic policy gradient (D4SPG) algorithm, which is our main contribution. More specifically, it newly designs a minimax learning framework that combines the critics of the two players and proposes a symplectic policy gradient adjustment method to find a better policy gradient. Simulations show that both algorithms converge to the Nash equilibrium in most cases, but D4SPG can learn the Nash equilibrium more accurately and efficiently, especially in Hamiltonian games. Moreover, it can handle games with complex dynamics, which is challenging for traditional methods.

    Abstract Exhaustive exercise (EE) induces kidney injury, but its concrete mechanism has not been fully elucidated. Hepatoprotective effects of dipsacoside B (DB) have been found previously, involving in autophagy induction. However, whether DB exerts renal protective effect and its potential mechanism are still unknown. The present study aimed to investigate the benefit of DB in EE-induced kidney injury and decipher its underlying mechanism. Here, we found that DB ameliorated EE-induced renal dysfunction and renal histopathological injury in rats. DB possessed anti-inflammatory, anti-oxidative, and anti-apoptotic functions in kidneys of exercise-induced exhausted rats. Besides, DB improved autophagy function in kidneys of EE rats. Mechanically, activation of the adenylate-activating protein kinase (AMPK)/mammalian target of rapamycin (mTOR) pathway was implicated in the kidney injury-relieving effects and autophagy restoration induced by DB. Collectively, these findings provide reference for the clinical application of DB in preventing and managing EE-induced kidney injury.

    Abstract The social and emotional competence of adolescents serves as the cornerstone for their success and future development. This study aims to explore the impact of distributed leadership on the social and emotional competence of adolescents, examining the mediating roles of student-centered teaching practices and teacher self-efficacy. Utilizing survey data from 7246 Chinese adolescents in the SESS project, the study employs a multi-level structural equation modeling approach for data analysis. The results indicate that distributed leadership positively predicts the social and emotional competence of adolescents. Furthermore, distributed leadership exerts indirect effects on adolescents' social and emotional competence through the independent mediating roles of student-centered teaching practices and teacher self-efficacy, as well as a sequential mediation process involving student-centered teaching practices leading to teacher self-efficacy. This study elucidates how distributed leadership facilitates the development of adolescents' social and emotional competence, confirming the supportive factors influencing these crucial capacities. Simultaneously, it provides valuable insights into the daily practices of teachers, principals, and administrators.
