The Influence of Multiple Factors on Musicology Doctoral Students' Academic Performance: An Empirical Study Based in China

As doctoral education evolves globally, the focus intensifies on doctoral candidates' academic performance and psychological well-being. Previous research has studied the effects of individual, societal, and environmental factors on students' academic achievements. However, there is still a lack of investigation into how these factors interact, especially in the domains of arts. This study surveyed 213 Chinese musicology doctoral students and adopted Partial Least Squares Structural Equation Modeling (PLS-SEM) to evaluate how various factors affect academic and mental health outcomes. The analysis shows that factors including teacher support, student engagement, and well-being positively influence academic performance, while academic anxiety negatively impacts academic performance. Moreover, variables help diminish academic anxiety, encompassing self-efficacy, parental support, time management skills, and student engagement. Meanwhile, enhanced doctoral students' well-being is related to robust teacher support, facilitating conditions, and active student engagement. Notably, students who experience academic anxiety about their studies generally have lower well-being. These findings indicate that alleviating academic anxiety, refining academic resources, and reinforcing mental health supports can foster academic and psychological outcomes for doctoral students. Our study contributes vital empirical data to developing higher education policies, benefiting doctoral students' mental health and academic success.

The impact of urban green space on the health of middle-aged and older adults

Introduction

Urban green space is one of the most closely related ecosystem services to residents' lives, and it can be regarded as a preventive public health measure. Residents living in parks and other green environments can help improve their physical and mental health, reduce stress and even prevent crime and violence. Therefore, based on the actual situation in China, this paper analyzes the relationship between urban green space and the health of middle-aged and older adults and its mechanisms.

Methods

This study used multiple linear regression, based the data from the China Health and Retirement Longitudinal Study (CHARLS) in 2013, 2015, and 2018, to explore the relationship between urban green space and the health of middle-aged and older adults. At the same time, group regression was conducted to identify the heterogeneity of health effects of urban green space.

Results

The research shows that the increase of urban green space areas can significantly improve the health status of middle-aged and older adults. After a series of robustness tests, the results are still valid. In addition, the health effects of urban green space are different because of gender, age, education level, marital status residence, geographical location of the respondents and park quantity distribution. Further research found that reducing hot weather and optimizing air quality are the potential mechanisms of urban green space affecting the health of middle-aged and older adults, providing new evidence for the causal mechanism between urban green space and the health of middle-aged and older adults.

Discussion

This study expanded the research scope of the impact of urban green space on the health of middle-aged and older adults, covering a representative sample in China. The results show that urban green space has an important impact on the health of middle-aged and older adults. Policy suggestions are made to help cities optimize the landscape and residents to enjoy ecology.
