How green growth affects carbon emissions in China: the role of green finance
Accelerating the green transition of the economy is an effective way to conserve energy and reduce emissions, and its impact on the greenhouse effect deserves in-depth discussion. Based on this, we examine the potential effect of China's green growth on carbon dioxide (CO 2 ) emissions by applying provincial panel data from 2004 to 2018. The regional heterogeneity and how does green finance affect the green growth-CO 2 nexus are also checked. The primary findings imply that: (i) China's green growth achieves preliminary results, and its impact on CO 2 emissions is significantly negative. Also, green finance can facilitate carbon emission reduction; (ii) significant regional heterogeneity exists within various regions. Only in the central and western regions can green growth effectively reduce CO 2 emissions, and in the eastern and central regions, green finance is conducive to promoting carbon reduction; and (iii) the mediating role of green finance is significant. In other words, China's green growth not only mitigates the greenhouse effect directly, but also affects CO 2 emissions indirectly by accelerating the development of green finance.
Social Support and Academic Burnout Among University Students: A Moderated Mediation Model
An increasing number of studies have been carried out to investigate the relationship between social support and study motivation among university students, but underlying mechanisms behind this pathway have not been fully verified. In the present study, we aimed to test the effect of social support on academic burnout (decrease in study motivation); examine the mediating effect of life satisfaction on the association between social support and academic burnout; and explore whether this mediating effect varied across (moderated mediation) students of different socioeconomic status (SES). Data for 503 students were collected in a Chinese university through a composited survey regarding social support, life satisfaction, SES, and academic burnout. Data analysis and the investigation of combined effects in the model were carried out via conditional process modeling. Results indicated that social support was negatively associated with academic burnout. In addition, life satisfaction had a partial mediation effect on the relationship between social support and academic burnout, and SES moderated this mediation effect. Specifically, the mediation effect was found to be more significant among students in the high SES group than those in the lower one. This study is novel in that it establishes empirically how academic burnout is associated with a typical society analytical variable (ie, social support) among students in tertiary education. It also investigates an alternative scenario to explain the underlying mechanism of social support on academic burnout against the most popular explaining model. Implications of the study for effective elimination of the decrease in study motivation across students with different SES are discussed.
Poverty Alleviation Relocation, Fuelwood Consumption and Gender Differences in Human Capital Improvement
The aim of poverty alleviation relocation is to break the vicious cycle of poverty and ecological degradation. The improvement of human capital, specifically women’s human capital, is important to realize the poverty alleviation and sustainable development of relocated peasant households. Based on the survey data of 902 peasant households in southern Shaanxi in 2020, using the PSM model and the mediation effect test model, this paper explores the impact of participation in relocation on human capital from the perspective of gender differences, and the mediation effect of fuelwood consumption in the effect of participation in relocation on the human capital of peasants with different genders. The results show that firstly, in general, participation in relocation effectively improves the human capital of peasants. Secondly, there are gender differences in the improvement of the human capital of relocated peasants. Compared with male peasants, the health level of female peasants is significantly improved. Finally, fuelwood consumption plays an important mediation role in the impact of participation in relocation on human capital and the mediation role is more significant in improving the human capital of relocated female peasants.
A moderated mediation analysis of occupational stress, presenteeism, and turnover intention among occupational therapists in Korea
Objectives Presenteeism is undoubtedly a widespread phenomenon in organizations. Research on presenteeism has been conducted for decades in the broader workforce (eg, nurses, doctors, teachers, police officers). Occupational stress and turnover intention in occupational therapy have been extensively studied. However, the effect of presenteeism on the relationship between occupational stress and resultant turnover intention among occupational therapists is unclear. This study aims to explore the mediating effect of presenteeism and moderating effect of perceived organizational support in the relationship between occupational stress and turnover intention among occupational therapists in Korea. Methods We conducted an individual and cross‐sectional analysis of 257 occupational therapists from various health care institutions in Korea. Data were collected and hypotheses were tested via Process macro. Quantitative analyses were conducted with SPSS 26 and LISREL 8.54. Results Occupational stress was strongly related to presenteeism, which in turn predicted turnover intention. Presenteeism played a mediating role between occupational stress and turnover intention. Moreover, occupational therapists’ perception of organizational support acted as an important mechanism through which presenteeism mediated the relationship between occupational stress and turnover intention. Conclusions This study highlights the need to maximize employee productivity and retain talent by providing managers with insight into the mechanism of presenteeism in relation to occupational stress and turnover intention among occupational therapists in Korea.
From Healthy Eating to Positive Mental Health in Adolescents: A Moderated Mediation Model Involving Stress Management and Peer Support
Background: Adolescent mental health is a growing public health concern, with increasing prevalence of anxiety, depression, and emotional dysregulation. While nutrition is a recognized factor in physical health, its role in mental well-being, especially through holistic models, remains underexplored. Objectives: This study examines a moderated mediation model in which perceived healthy eating (self-rated diet quality) was associated with positive mental health (PMH) in adolescents, mediated by stress management and moderated by peer social support. Methods: A cross-sectional study was conducted with a sample of 505 adolescents aged 13 to 15 years (mean age 13.62). Using PROCESS Model 14, we tested a moderated mediation model where perceived nutrition served as the predictor, stress management as the mediator, and PMH as the outcome. Peer support was included as a moderator of the mediation pathway. Gender, age, nationality and educational variables were controlled for in the analysis. Results: The model explained 36% of the variance in PMH. Perceived healthy eating was significantly associated with better stress management (B = 0.20, p < 0.001), which in turn was related to higher levels of PMH (B = 6.38, p < 0.001). Peer support played a moderating role between stress management and PMH. Conclusions: These findings underscore the importance of promoting nutritional awareness and adolescents’ self-perception of healthy eating to support both physical and emotional well-being. Interventions should adopt a holistic approach that integrates emotional regulation strategies and leverages peer influence to enhance mental health outcomes. Given the alarming rates of mental health issues in youth, nutrition-based programs that incorporate psychosocial components may offer a promising avenue for prevention and promotion.
Cervical Cancer Screening and Associated Barriers among Women in India: A Generalized Structural Equation Modeling Approach
Exploring the barriers and facilitators of cervical cancer screening (CCS) is essential to reduce the incidence and mortality, particularly in low and middle-income countries. The present study investigates the direct, indirect, and total effects of the barriers and facilitators on CCS in India through the generalized structural equation modeling using data from women files of the fourth round of the National Family Health Survey (NFHS-4). Generalized structural equation models were used to quantify the hypothetical pathway via fitting a series of regression equations. Age, body mass index, religion, years of schooling, awareness of sexually transmitted infection, contraception use, lifetime number of sex partners, number of children, and wealth index were shown to have significant direct effects on the CCS. Older women had 1.16 times the odds of getting screened for cervical cancer as compared to their younger counterpart. The odds of CCS among the women in richest wealth quintile is 2.50 times compared to the poorest. Those who are aware of STIs have 1.39 times the odds of getting screened for cervical cancer. Wealth index, years of schooling, and religion have a substantial indirect and total impact on the CCS. The findings will aid in policy formulations for enhancing the CCS in India.
Positive Mental Health in Adolescents: Implications of Cognitive–Emotional Processes and Social Support
Background: Adolescence is a key period of development characterized by emotional, cognitive, and social changes that impact positive mental health (PMH). While social support is a well-established protective factor, cognitive and emotional processes, such as cognitive fusion and regulation of distress, also play a critical role. Objective: This study aimed to examine the relationship among various cognitive (i.e., cognitive fusion), emotional (i.e., regulation of distress), and social determinants (i.e., social support) in adolescents’ PMH, as their interplay could reflect theoretical models highlighting how these factors jointly shape adolescents’ mental health. Methods. A cross-sectional study was conducted with 505 adolescents (aged 13–15 years) in Spain. Participants completed online questionnaires assessing sociodemographic variables, cognitive fusion, regulation of distress, PMH, and social support from friends. Descriptive statistics, correlation analyses, and mediation and moderated mediation models were conducted, adjusting for relevant covariates. Results: Cognitive fusion was negatively correlated with regulation of distress, PMH, and social support, whereas regulation of distress showed a positive association with both PMH and social support. Mediation analysis indicated that regulation of distress significantly mediated the relationship between cognitive fusion and PMH. Furthermore, peer support moderated this mediated relationship: higher levels of support mitigated the negative impact of regulation of distress on PMH. Sociodemographic analyses revealed that girls, non-national students, and those receiving educational support showed less favorable outcomes. Conclusions: Cognitive, emotional, and social variables jointly influence adolescents’ PMH. Emotional regulation serves as a mediator of cognitive fusion and PMH, while social support from peers mediates the impact of psychological distress. Targeted interventions should prioritize emotional regulation strategies and enhancing peer support, especially among more vulnerable groups.
COMPOSITIONAL MEDIATION ANALYSIS FOR MICROBIOME STUDIES
Motivated by recent advances in causal mediation analysis and problems in the analysis of microbiome data, we consider the setting where the effect of a treatment on an outcome is transmitted through perturbing the microbial communities or compositional mediators. The compositional and high-dimensional nature of such mediators makes the standard mediation analysis not directly applicable to our setting.We propose a sparse compositional mediation model that can be used to estimate the causal direct and indirect (or mediation) effects utilizing the algebra for compositional data in the simplex space. We also propose tests of total and component-wise mediation effects. We conduct extensive simulation studies to assess the performance of the proposed method and apply the method to a real microbiome dataset to investigate an effect of fat intake on body mass index mediated through the gut microbiome.
Green Credit, Financial Constraint, and Capital Investment: Evidence from China’s Energy-intensive Enterprises
The green credit policy is an important green financial tool that can achieve the win–win scenario with economic development and environmental protection through the reasonable allocation of credit resources. Using the green credit guidelines (GCGs) in China as a quasi-natural experiment, this study explored the impacts of the green credit policy on the capital investment of energy-intensive enterprises in a difference-in-differences framework and established the mediation effect model to analyze the mechanisms. The empirical results showed that the capital investment of energy-intensive enterprises was significantly reduced after the promulgation of the GCGs. Considering the intermediary paths along with the green credit policy on energy-intensive investment through financial constraints, the total bank loans and long-term bank loans played partial intermediary roles, whereas the short-term bank loans as mediator variable showed no significant intermediary effect. The findings of this study illustrated that the green credit policy has been well implemented and promoted in China. It inhibited energy-intensive investment, which is of great significance to improving the efficiency of resource utilization and promoting green and low-carbon development.
