Effects of Chinese Language Learning Anxiety on the Mental Health of International Students in China: The Chain Mediating Effect of Campus Adaptation and Academic Resilience.

Introduction: Studies have shown that Chinese language learning anxiety among international students in China can negatively affect their psychological adjustment. However, the specific effects and conditions of learning anxiety need to be further investigated. This study explored the mediating effects between Chinese language learning anxiety and psychological adjustment of international students in China. Methods: Chinese Learning Anxiety Scale, Campus Adaptability Scale for International Students in China, Academic Resilience Questionnaire for International Students in China, Zung's Self-Rated Depression Scale were administered to 307 international students from Nanjing Normal University in China, including 165 male students and 131 female students, aged 19-28 (M =21.42; SD = 1.528). Results: Chinese language learning anxiety significantly predicted the psychological well-being of international students after controlling for gender and age variables. Furthermore, Chinese language learning anxiety predicted the mental health of students through the independent mediating effect of campus adaptation and academic resilience, as well as the chain mediating effect of campus adaptation and academic resilience. Conclusion: The study has theoretical and practical significance for improving international students' psychological adaptation and health, and implications for those involved in the management and teaching of international students in China. The research conclusions are as follows: firstly, when the Chinese learning anxiety of international students in China is strong, their campus adaptation and psychological resilience are reduced, and levels of depression increase; secondly, grades are significantly correlated with anxiety dimensions, and higher grades are associated with lower anxiety levels; finally, the mediating effects of campus adaptation and academic resilience were significant, together with a significant chain mediating effect of campus adaptation and academic resilience.

Dynamic routing, modulation, and spectrum assignment based on fuzzy logic control in elastic optical networks.

Considering the constantly changing network resources and randomly generated spectrum fragmentation problem, a dynamic routing, modulation, and spectrum assignment based on the fuzzy logic control (RMSA-FLC) algorithm is proposed in this paper. A fuzzy logic control (FLC) system based on the degree of fragmentation optimization and the degree of link selection is constructed. The path-control weight (PW) is achieved as the output of the FLC system, and the path and spectrum allocation scheme with the maximum PW is selected for the immediate reservation requests. The simulation results show that the proposed RMSA-FLC algorithm can effectively reduce the blocking probability and improve the spectrum resource utilization in a dynamic elastic optical network.
