We discuss the uniformly asymptotic estimate of the finite-time ruin probability for all times in a generalized compound renewal risk model, where the interarrival times of successive accidents and all the claim sizes caused by an accident are two sequences of random variables following a wide dependence structure. This wide dependence structure allows random variables to be either negatively dependent or positively dependent.

AbstractEmotions play a crucial role in the learning process, yet there is a scarcity of studies examining emotion dynamics in problem-solving with fine-grained data and advanced tools. This study addresses this gap by investigating the emotional trajectories during self-regulated learning (SRL) phases (i.e., forethought, performance, and self-reflection) among 47 medical students utilizing an intelligent tutoring system. Real-time facial expressions were analyzed through recurrence quantification analysis alongside an examination of electrodermal activities (EDA) across the SRL phases. The findings reveal that emotion stability varied across SRL phases, with students exhibiting more stable emotions during the performance phase. Compared to the forethought and self-reflection phases, students had less frequent and lower intensity of emotional arousal in the performance phase. Moreover, we found that students with better performance demonstrated more stable emotions in the forethought phase, less stable emotions in the self-reflection phase, and a higher level of emotional arousal in the self-reflection phase. These insights highlight the temporal and dynamic nature of emotions in SRL, offering methodological and educational implications for leveraging facial expressions and EDA to monitor and enhance students' emotional experience during problem-solving.

Chinese university undergraduates' personality types were investigated from the perspective of androgyny as the ideal gender role type. Based on Bem's (1974) 4 gender role types, 434 undergraduates were classified as masculine, feminine, androgynous, or undifferentiated. The relationships
among personality type, trait coping style, and level of self-esteem were examined. Results showed that the students were mainly in 2 gender role types: androgynous and undifferentiated. Gender and grade had a significant impact on the distribution of gender role types. The androgynous group
had the highest self-esteem level and tended to use positive coping strategies. Androgyny was assessed as an ideal gender role type, relative to the 3 other types.
