This study examines the impact of green financial policies, specifically green bonds and green credit, on investments in green energy across 23 OECD (The Organization for Economic Co-operation and Development) member countries from 2010 to 2021. Analyzing panel data using CUP-FM analysis, it finds that both green bonds and green credit significantly foster investments in green resource projects, with green bonds showing greater sensitivity. Conversely, green fiscal policies, particularly green taxes, prove ineffective and sometimes counterproductive. The research highlights a positive correlation between increased investments in green resources, growth in green economies, and sustainable utilities trade, while emphasizing the detrimental effect of public health costs on green project development. The study underscores the importance of appropriate policies to promote investments in renewable resources, spanning green finance, green fiscal policies, green economic growth, and sustainable utilities trade.

Background: The urban ambient air quality has been largely improved in the past decade. It is unknown whether childhood asthma prevalence is still increasing in ever top‐ranking city of Shanghai, whether the improved air quality is beneficial for children's asthma and what time window of exposure plays critical roles. Methods: Using a repeat cross‐sectional design, we analyzed the association between early life exposure to particles and wheezing/asthma in each individual and combined surveys in 2011 and 2019, respectively, in 11,825 preschool children in Shanghai. Results: A significantly lower prevalence of doctor‐diagnosed asthma (DDA) (6.6% vs. 10.5%, p < 0.001) and wheezing (10.5% vs. 23.2%, p < 0.001) was observed in 2019 compared to 2011. Exposure to fine particulate matter (PM2.5), coarse particles (PM2.5–10) and inhalable particles (PM10) was decreased in 2019 by 6.3%, 35.4%, and 44.7% in uterus and 24.3%, 20.2%, and 31.8% in infancy, respectively. Multilevel log‐binomial regression analysis showed exposure in infancy had independent association with wheezing/DDA adjusting for exposure in uterus. For each interquartile range (IQR) increase of infancy PM2.5, PM2.5–10 and PM10 exposure, the odds ratios were 1.39 (95% confidence interval (CI): 1.24–1.56), 1.51 (95% CI:1.15–1.98) and 1.53 (95% CI:1.27–1.85) for DDA, respectively. The distributed lag non‐linear model showed the sensitive exposure window (SEW) was 5.5–11 months after birth. Stratified analysis showed the SEWs were at or shortly after weaning, but only in those with <6 months of exclusive breastfeeding. Conclusions: Improved ambient PM benefits in decreasing childhood asthma prevalence. We firstly reported the finding of SEW to PM at or closely after weaning on childhood asthma.

The effect of scientific training on course learning in undergraduates is still controversial. In this study, we investigated the academic performance of undergraduate students with and without scientific training. The results show that scientific training improves students' test scores in general medical courses, such as biochemistry and molecular biology, cell biology, physiology, and even English. We classified scientific training into four levels. We found that literature reading could significantly improve students' test scores in general courses. Students who received scientific training carried out experiments more effectively and published articles performed better than their untrained counterparts in biochemistry and molecular biology examinations. The questionnaire survey demonstrated that the trained students were more confident of their course learning, and displayed more interest, motivation and capability in course learning. In summary, undergraduate academic performance is improved by scientific training. Our findings shed light on the novel strategies in the management of undergraduate education in the medical school.
