It has been demonstrated that music can be an effective tool for shaping the future of college students. This study aimed to investigate the effects of college students’ participation in group music activities on their pro-social behavior, and for the first time introduced the psychological variables of “positive social connections” and “perceived peer support”. The results of this study show the following: (1) Group music activity participation is positively associated with pro-social behavior. (2) Positive social connections serve as a mediator between college student group music activity participation and college students’ pro-social behavior. (3) Perceived peer support serves as a mediator between college student group music activity participation and college students’ pro-social behavior. (4) Positive social connections and perceived peer support interlock to shape the relationship between group music activity participation and pro-social behavior. This study explores the intrinsic factors of college students’ participation in group music activities to promote their pro-social behavior from the dual perspectives of music psychology and behavioral psychology, provides empirical support for educational practice, emphasizes the importance of group music activities in promoting the development of college students’ pro-social behavior, and provides insights into new perspectives for college students’ overall healthy development.

With the widespread use of sustainable building materials and the rise of emotional design, the use of wooden elements in public large-scale architecture has garnered significant attention. In public cultural spaces, especially music halls, although previous research has explored the aesthetic value and functional applications of wood in architecture, the micro-level exploration of how wooden design influences user perception and satisfaction has not been fully addressed. Therefore, this study uses a sample of 965 offline users of wooden music halls and applies Covariance-Based Structural Equation Modeling (CB-SEM) to investigate the pathways through which wooden design perception shapes user satisfaction. The results indicate: (1) Wooden design perception positively influences user satisfaction in wooden music halls; (2) Perceived restorativeness and musical resonance independently mediate the relationship between wooden design perception and satisfaction; (3) Wooden design perception positively influences user satisfaction through the chain mediation effect of perceived restorativeness and musical resonance. This study highlights how wooden design, through visual and tactile design, creates a profound immersive experience and emotional resonance, thereby optimizing the user experience and enhancing satisfaction in music halls. This research fills the gap in emotional and sensory experience studies in the design of wooden architecture in cultural venues, innovatively combining Emotional Design Theory and Immersion Theory, and proposes a new theoretical framework for how wooden design influences user satisfaction through perceived restorativeness and musical resonance, providing a fresh perspective for the field of architectural design. This study also provides theoretical support and actionable recommendations for the design practice of wooden music halls, helping designers better integrate cultural symbolism, perceived restorativeness, and multisensory experiences in space planning, material selection, and overall design.

We propose a novel dynamic gradient descent (DGD) framework integrated with reinforcement learning (RL) for AI-enhanced indoor environmental simulation, addressing the limitations of static optimization in dynamic settings. The proposed method combines a hybrid optimizer—stochastic gradient descent with momentum and adaptive learning rates—with an RL-driven meta-controller to dynamically adjust hyperparameters in response to real-time environmental fluctuations. The core innovation lies in the time-varying optimization landscape, where a Transformer-based policy network modulates the learning process based on a reward signal that balances prediction accuracy and parameter stability. Furthermore, the system employs a multilayer perceptron predictor trained on computational fluid dynamics-augmented data to model nonlinear thermal–airflow interactions, replacing conventional lumped-parameter models. The integration of these components enables autonomous adaptation to short-term disturbances (e.g., occupancy changes) and long-term drifts (e.g., seasonal variations) without manual recalibration. Experiments demonstrate that the framework significantly improves simulation accuracy and control efficiency compared to existing methods. The contributions include a unified adaptive optimization-RL architecture, a closed-loop hyperparameter control mechanism, and scalable implementation on GPU-accelerated hardware. This work advances the state-of-the-art in intelligent building systems by enabling self-tuning simulations for real-world dynamic environments.

The present study aims to investigate how the safety cognition bias of high-altitude workers in different age groups in the construction industry affects their unsafe behaviors. A theoretical framework involving safety cognition bias, risk-taking propensity, work experience, and unsafe behaviors was constructed. The empirical analysis was conducted using structural equation modeling. The results indicate that safety cognition bias has a significant positive effect on the unsafe behaviors of high-altitude workers. Risk-taking propensity plays a mediating role in this relationship, with partial mediation for the new generation of high-altitude workers and full mediation for the older generation. Moreover, work experience plays a crucial role in moderating the relationship between safety cognition bias and unsafe behaviors, specifically showing a significant moderating effect on the new generation of high-altitude workers, while its impact on the older generation is not significant. These findings provide theoretical support and practical guidance for reducing unsafe behaviors in high-altitude construction work, enhancing the safety management level of construction workers.

With the continuous development of the construction industry, work pressure faced by construction workers has been increasing, leading to a growing prominence of job burnout that adversely affects workers’ physical and mental health as well as work efficiency. Constantly exposed to high-pressure environments, construction workers are prone to symptoms such as emotional exhaustion, depersonalization, and diminished personal accomplishment, which in turn impair their work performance and quality of life. However, existing literature has largely overlooked the potential role of leisure activities such as music in alleviating job burnout. Although music is widely recognized as an effective tool for emotional regulation, its application and impact among construction workers remain underexplored. Based on a sample of 1086 construction workers (71.09% male, 48.99% aged 36–45), this study examines four dimensions of music engagement, including Time Commitment (TC), Economic Spending (ES), Emotional Investment (EI), and Personal Participation (PP), and investigates how these dimensions, through the mediating role of leisure crafting (LC), negatively influence job burnout (JB) among this population. This study employed covariance-based structural equation modeling (CB-SEM) with a sample of 1086 construction workers (71.09% male, 48.99% aged 36–45) to examine how four dimensions of music engagement, namely Time Commitment (TC), Economic Spending (ES), Emotional Investment (EI), and Personal Participation (PP), influence job burnout through leisure crafting. The results show that: (1) time commitment, economic spending, emotional investment and personal participation all have a negative influence on job burnout; and (2) leisure crafting mediates the effect of music engagement by construction workers on job burnout. This study emphasizes the necessity of incorporating mental health interventions into high-pressure work environments, providing guidance for companies to develop more flexible and effective employee care and welfare policies. This research therefore holds significant theoretical and practical value, as it promotes sustainable development in the construction industry, improves workers’ well-being and enhances the design of related work environments.

Academic burnout among college students is an important concern in educational psychology and student well-being. This cross-sectional study examined the associations among group music activity participation, social connectedness, collective effervescence, and academic burnout among non-music-major college students with recent group music participation. A questionnaire survey was conducted among 1027 college students in China who had participated in at least one group music activity during the previous semester. Covariance-based structural equation modeling (CB-SEM) was used to examine whether group music activity participation was associated with academic burnout directly and indirectly through social connectedness and collective effervescence, including a proposed sequence from social connectedness to collective effervescence. Fuzzy-set qualitative comparative analysis (fsQCA) was further used to examine which combinations of group music activity participation, social connectedness, and collective effervescence were associated with low academic burnout. The SEM results showed that higher group music activity participation was significantly associated with lower academic burnout. Social connectedness and collective effervescence were involved in significant individual indirect associations, and the serial indirect association involving social connectedness followed by collective effervescence was also statistically supported. The fsQCA results showed that no single condition constituted a necessary condition for low academic burnout. The joint presence of high group music activity participation, high social connectedness, and high collective effervescence formed a sufficient configuration associated with low academic burnout (consistency = 0.896, coverage = 0.647) under the present sample and analytical conditions. Taken together, the findings suggest that group music participation, relational connectedness, and shared emotional experience are meaningfully associated with differences in academic burnout among non-music-major college students. These findings provide a complementary variable-centered and configurational perspective on the psychosocial correlates of group music participation and may inform future longitudinal research and campus-based student well-being initiatives.
