Chinese Stock Market Efficiency of Capital Allocation Function

Using the efficiency of capital allocation function to characterize the stock market system efficiency.Using panel data analysis method,from a regional perspective empirical analysisto implement the stock market during the capital allocation function efficiency issue approval system for China.The results show: the efficiency of resource allocation of China stock market is lower,and stock market system is inefficient.Point:Chinese stock market institutional change should transform from government-led to market-oriented and increase penalties for violations to cultivate rational and mature investors in order to achieve the stock market system function better,enhance system efficiency

You Can Generate It Again: Data-to-text Generation with Verification and Correction Prompting

Despite significant advancements in existing models, generating text descriptions from structured data input, known as data-to-text generation, remains a challenging task. In this paper, we propose a novel approach that goes beyond traditional one-shot generation methods by introducing a multi-step process consisting of generation, verification, and correction stages. Our approach, VCP(Verification and Correction Prompting), begins with the model generating an initial output. We then proceed to verify the correctness of different aspects of the generated text. The observations from the verification step are converted into a specialized error-indication prompt, which instructs the model to regenerate the output while considering the identified errors. To enhance the model's correction ability, we have developed a carefully designed training procedure. This procedure enables the model to incorporate feedback from the error-indication prompt, resulting in improved output generation. Through experimental results, we demonstrate that our approach effectively reduces slot error rates while maintaining the overall quality of the generated text

Adverse childhood experiences and age-trajectories of depressive symptoms in older adults from China

Background Adverse childhood experiences (ACEs) have profound lifelong consequences. Less is known about their impact on outcomes in late life, such as psychological distress in older adults. Moreover, there is a paucity of evidence on associations of ACEs with age-trajectories in depressive symptoms, especially with distinct patterns of trajectories. We investigated associations between ACEs and trajectories of depressive symptoms at mid-to-older ages in a Chinese population sample. Methods We used the longitudinal data from the China Health and Retirement Longitudinal Survey (13846 participants ≥45y). Depressive symptoms were measured by CES-D10 (Centre for Epidemiologic Studies Depression Scale) at four waves (2011-18). A range of ACEs (<17y) were retrospectively reported by participants. Growth Mixture Models were used to identify distinct age-trajectories of depressive symptoms and their associations with ACEs. Results We identified two trajectory groups: (1) persistent high (men 14%; women 19.2%) and (2) low/normal levels of depressive symptoms. Several ACE measures were associated with increased risk of having persistent high levels of depressive symptoms (mid-to-older ages) after adjusting for other ACEs, sex, childhood SES (financial status, parental education, occupation), adult SES (education, financial status, urban/rural residence), health behaviors and limitations in daily activities. For example, adjusted OR was 1.35 (95% CI:1.17,1.55) for physical abuse (28.2%), 1.38(1.19,1.59) for domestic violence (24.3%), 1.48(1.23,1.78) for parental drinking, drug or mental health problems (9.4%), 1.59(1.38,1.84) for those had a bedridden parent (18.7%). Conclusions ACEs have a long lasting effect on trajectories of depressive symptoms in older adults, independent of childhood SES and adult factors, highlighting the need to act early to reduce the long lasting impact on mental health in later life. Key messages • Adverse childhood experiences are associated with persistent high levels of depressive symptoms from mid-to-older ages. • Associations are independent of childhood SES and adult factors
