Abstract

Psychological resilience and emotional well-being are fundamental determinants of children’s healthy development, academic engagement, and long-term mental health. Increasing exposure to academic pressure, social challenges, family instability, and environmental stressors has intensified the need for preventive school-based interventions that strengthen children’s adaptive capacities before psychological difficulties become more severe. This study aimed to examine the effectiveness of comprehensive school-based interventions in promoting psychological resilience and well-being among primary school children. A mixed-methods sequential explanatory design was employed involving 960 students from ten elementary schools implementing resilience-oriented educational programs. Quantitative data were collected using validated measures of psychological resilience, emotional well-being, emotional regulation, self-efficacy, school connectedness, and social competence, and analyzed through generalized linear mixed-effects modeling, structural equation modeling, mediation analysis, and repeated-measures analysis of variance. Qualitative evidence was obtained through interviews, focus group discussions, classroom observations, and institutional document analysis, followed by thematic interpretation. Findings revealed significant improvements in psychological resilience, emotional well-being, adaptive coping, emotional regulation, self-efficacy, school connectedness, and academic engagement, supported by stronger teacher support, positive peer relationships, and greater family involvement. Psychological resilience emerged as the principal mechanism linking school-based interventions with improved well-being and positive educational outcomes. Results indicate that sustainable child well-being depends on coordinated interaction among resilience education, supportive school climate, teacher engagement, counseling services, and family participation. The proposed framework offers practical guidance for developing comprehensive whole-school programs that foster children’s psychological resilience and lifelong well-being

Abstract

Ground-state cooling of nanomechanical resonators is a fundamental requirement for realizing high-fidelity quantum control, precision sensing, and coherent quantum information processing. Conventional resolved-sideband cooling has achieved remarkable progress; however, quantum back-action, optical losses, thermal fluctuations, and finite cavity linewidths continue to limit cooling performance under realistic experimental conditions. This study aimed to evaluate the effectiveness of squeezed light injection in enhancing ground-state cooling while investigating the interactions among optical squeezing, optomechanical coupling, cavity dynamics, quantum back-action suppression, and thermal phonon reduction within the resolved-sideband regime. A mixed-methods sequential explanatory design was employed using 14,000 large-scale optomechanical simulations complemented by experimental benchmark datasets, cavity calibration records, laboratory implementation reports, and expert evaluations. Quantitative data were analyzed through generalized linear mixed-effects modeling, Monte Carlo uncertainty estimation, sensitivity analysis, and multivariate statistical techniques, whereas qualitative evidence was interpreted using thematic analysis of experimental observations and technical documentation. Findings demonstrated that squeezed-light-assisted cooling significantly reduced the final mean phonon occupation, improved ground-state occupation probability, suppressed quantum back-action, preserved mechanical coherence, and enhanced cooling efficiency across multiple optomechanical configurations. Results indicate that engineered quantum fluctuations provide an effective mechanism for overcoming practical limitations associated with conventional sideband cooling. The proposed framework establishes a robust foundation for developing scalable optomechanical platforms supporting quantum sensing, hybrid quantum systems, precision metrology, and future quantum information technologies.
