    Evaluation of Health Associations With Height‐Normalised Abdominal Body Composition Indices: A Single‐Centre Cross‐Sectional Study by Yupeng Liu, Hangqian He, Keyu Qian, Yufeng Huang, Xuemei Ao, Xudong Shi, Binye Ruan, Ru Xue, Xiaoyi Fu, Shuran Wang

    Published 2024-12-01
    “…ABSTRACT Background Traditional metrics such as body mass index (BMI) and waist circumference (WC) fail to accurately assess the health outcomes associated with abdominal adiposity, because they neglect the intricacies of adipose tissue distribution. Notably, the variability in body composition scaled to height remains underexplored in Chinese demographics. …”

    Investigating the Mediating Effect of Credit Rating on the Relationship between Corporate Governance Quality and Stock Liquidity based on the Composite Liquidity Approach by Amin Pourrezaei Nav, Hamzeh Didar, Farzad Ghayour

    Published 2024-11-01
    “…To test the research hypotheses, a panel data model was used. Emphasizing the reverse structure of the composite liquidity measure, the findings of the study indicated that corporate governance quality has a positive and significant impact on stock liquidity and that credit ratings play a partial mediating role in the relationship between corporate governance quality and stock liquidity.IntroductionThe purpose of this study was to investigate the mediating effect of credit rating on the relationship between the quality of corporate governance and stock liquidity. …”
