Abstract With oily wastewater treatment emerging as a critical global issue, porous media and shear forces have received significant attention as environmentally friendly methods for oil–water separation. This study systematically simulates the dynamics of oil-in-water emulsion demulsification under porous media and shear forces using a color-gradient Lattice Boltzmann model. The morphological evolution and demulsification efficiency of emulsions are governed by porous media and shear forces. The effects of porosity and shear velocity on demulsification are quantitatively analyzed. (1) The presence of porous media enhances the ability of the flow field to trap oil droplets, with lower More >

Abstract Objectives: Academic Evaluation Anxiety is a significant psychological concern among adolescents, with well-documented impacts on academic performance, emotional well-being, and school engagement. In Portugal, recent evidence suggests growing pressure on students to achieve high academic standards, with psychosocial variables such as resilience, perceived support, and school environment playing a crucial role. This study aims to examine the prevalence and psychosocial predictors of Academic Evaluation Anxiety in Portuguese students, and to identify risk and protective factors that inform educational practice. Methods: This cross-sectional, quantitative study analysed data from 3083 students (5th to 12th grade) from the… More >

Abstract Aiming at the issues of insufficient carrying capacity, limited flexibility, and weak source-network-load-storage coordination capability in distribution networks under the background of high-proportion new energy integration. This study proposes a bi-level optimization model for ADN integrating hybrid wind-solar-hydrogen-storage systems. First, an electro-hydrogen coupling system framework is constructed, including models for electrolytic hydrogen production, hydrogen storage, and fuel cells. Meanwhile, typical scenarios of wind-solar joint output are developed using Copula functions to characterize the variability of renewable energy generation. Second, a bi-level optimization model for ADN with electrolytic hydrogen production and storage systems is established: the… More >

Abstract Grounded in the Job Demands-Resources (JD-R) model, this study investigates the relationship between technostress and professional identity among 313 online international language teachers (82.11% female; 77.64% aged 24 and above; 63.87% with postgraduate education). It further examines the mediating role of growth mindset and the moderating effect of technical support. The results indicate that higher levels of technostress are associated with lower levels of professional identity. Growth mindset partially mediates this relationship: elevated technostress not only directly weakens teachers’ professional identity but also indirectly reduces it by undermining their growth mindset. Moreover, technical support significantly More >

Abstract This study examined the perceived teacher autonomy support effects on college students’ creativity, and the role of academic engagement and affect (positive and negative emotions) in that relationship. The study sample comprised 637 undergraduates (366 females, 271 males). Results from structural equation modelling with a moderated mediation framework indicated that perceived teacher autonomy support positively predicted college students’ self-reported creativity. Academic engagement partially mediated the relationship between autonomy support and creativity, whereby higher perceived autonomy support predicted greater academic engagement, which subsequently promoted creativity. Both positive and negative emotions strengthened the link between autonomy support More >

Abstract This study utilized a mediation model to examine the role of psychological capital and positive academic emotions in the relationship between school connectedness and academic engagement in adolescents. A sample of 389 Chinese adolescents (M_age = 13.43; 51.2% females) completed the Utrecht Work Engagement Scale-Student (UWES-S), the Achievement Emotions Questionnaire (AEQ), the Positive Psychological Capital Scale (PPCS), and the School Connectedness Scale (SCS). Structural equation modeling analysis yielded findings to suggest that higher school connectedness is associated with academic engagement. Psychological capital was associated with positive emotions, and higher psychological capital partially mediated the relationship between More >

Abstract Objectives: Recently, the global esports industry has experienced remarkable growth, leading to an expansion in the scale and influence of professional player communities. However, despite this outward growth, systems to protect players’ mental health remain inadequate. Comprehensive analysis of structural risk factors, including performance pressure, public evaluation, and career instability, remains insufficient. This study, aimed to explore stressors encountered by esports athletes, coping strategies, and the role of social support systems in safeguarding mental health. Using the transactional model of stress and coping, the job demands–resources model, and social support theory, the study adopts an… More >
