    尽管定期锻炼人群是衡量中国全民健身活动成功与否的关键指标,增加群众体育参与的有效政策方法仍不清楚。以前的研究表明,GDP,教育程度,体育资源,气象条件可能会影响定期锻炼的参与。因此,本研究首先分析了影响中国规律锻炼人群的宏观层面相关因素。
    我们利用普通最小二乘(OLS)回归和地理加权回归(GWR)来对关系进行理论化。分析包括来自中国大陆31个行政区的数据,在“十三五”期末报告。对数-对数模型使我们能够量化解释变量的边际效应(弹性)。
    OLS回归表明,地区GDP和受过大学教育的人口比例是重要的预测因素。在全局模型中,地区GDP和大学教育的边际效应分别为0.048和0.173。此外,GWR揭示了与经典胡线相对应的独特地理格局。
    虽然地区GDP在我们的模型中也是一个显著的相关性,弹性表明,大学教育对中国正常运动人群的影响是不对称的。因此,本文阐明了即将到来的“十五”计划的政策重点,强调扩大大学教育对增强群众体育参与的战略重要性。反过来,受过良好教育的民众可能会对公共卫生产生重大的二次影响,并有助于中国现代化道路的高质量发展。
    UNASSIGNED: Although the regular exercise population is a key metric for gaging the success of China\'s fitness-for-all activities, effective policy approaches to increase mass sports participation remain unclear. Previous research suggests that GDP, educational attainment, sports resources, and meteorological conditions could influence regular exercise participation. Therefore, this study first analyzed the macro-level correlates influencing China\'s regular exercise population.
    UNASSIGNED: We utilize ordinary least squares (OLS) regression and geographical weighted regression (GWR) to theorize the relationship. The analysis encompasses data from the 31 administrative regions of Mainland China, as reported at the end of the 13th Five-Year Plan period. The log-log model enables us to quantify the marginal effect (elasticity) of the explanatory variables.
    UNASSIGNED: The OLS regression showed that regional GDP and the proportion of the population with a university education were significant predictors. In the global model, the marginal effects of regional GDP and university education were 0.048 and 0.173, respectively. Furthermore, the GWR revealed a distinct geographic pattern that corresponds to the classic Hu Line.
    UNASSIGNED: While regional GDP was also a significant correlate in our model, the elasticity demonstrates that university education had an asymmetric effect on China\'s regular exercise population. Therefore, this paper sheds light on a policy priority for the upcoming 15th Five-Year Plan, emphasizing the strategic importance of expanding university education to enhance mass sports participation. In turn, a better-educated populace may yield significant secondary effects on public health and contribute to the high-quality development of the Chinese path to modernization.

    翻译延伸因子1α(EF1α)蛋白是一种高度保守的G蛋白,对于所有真核生物中的蛋白质翻译至关重要。EF1α在42°C的温度下在体外处理2h迅速变得不溶,但即使在长时间暴露于高达45°C的温度后,通常仍可在体内溶解,这表明在热胁迫下存在保持EF1α在植物细胞中可溶的保护机制。当暴露于45°C时,EF1α在体内快速不溶解,导致约40%的蛋白质在9小时后聚集。鉴于其在蛋白质翻译中的既定作用,热诱导的聚集最有可能影响伸长因子的功能。EF1α的GTP结合形式和GDP结合形式的组成型突变体的过表达导致耐热性显着降低。这些发现为支持EF1α的关键作用提供了证据,一种热敏蛋白,植物的耐热性。
    The translation elongation factor 1α (EF1α) protein is a highly conserved G protein that is crucial for protein translation in all eukaryotic organisms. EF1α quickly became insoluble at temperatures 42 °C treatment for 2h in vitro, but generally remained soluble in vivo even after being exposed to temperatures as high as 45 °C for an extended period, which suggests that protective mechanisms exist for keeping EF1α soluble in plant cells under heat stress. EF1α had fast in vivo insolubilization when exposed to 45 °C, resulting in about 40% of the protein aggregating after 9 h. Given its established role in protein translation, heat-induced aggregation is most likely to impact the function of the elongation factor. Overexpression of constitutive mutants in both GTP-bound and GDP-bound forms of EF1α resulted in significantly decreased heat tolerance. These findings provide evidence to support the critical role of EF1α, a thermosensitive protein, in the heat tolerance of plants.

    目前尚不清楚国内生产总值(GDP)和绿色是否对空气污染与呼吸系统疾病之间的关联具有额外的调节作用。利用分布滞后线性模型的时间分层案例交叉设计,我们分析了2016年1月1日至2019年12月31日北京6种污染物(PM2.5,PM10,NO2,SO2,O3和CO)与555,498例呼吸住院患者之间的关联.我们采用条件逻辑回归,根据气象条件进行调整,假期和流感,计算住院风险的百分比变化。随后,我们使用双样本z检验进行了亚组分析以研究潜在的效应修饰.PM2.5,PM10,NO2,SO2和O3每增加10μg/m3,导致0.26%的增加(95CI:0.17%,0.35%),0.15%(95CI:0.09%,0.22%),0.61%(95CI:0.44%,0.77%),1.72%(95CI:1.24%,2.21%),和0.32%(95CI:0.20%,0.43%)在招生中,分别。此外,CO水平增加1mg/m3导致2.50%(95CI:1.96%,3.04%)录取率上升。与NO2的链接(p<0.001),SO2(p<0.001),O3(在温暖的季节,p<0.001),居住在绿色水平较高的地区的患者中,CO(p<0.001)明显较弱。没有观察到GDP的显着修饰作用。绿色可以帮助减轻空气污染物的影响,而GDP的作用需要进一步研究。
    It is unclear whether Gross Domestic Product (GDP) and greenness have additional modifying effects on the association between air pollution and respiratory system disease. Utilizing a time-stratified case-crossover design with a distributed lag linear model, we analyzed the association between six pollutants (PM2.5, PM10, NO2, SO2, O3, and CO) and 555,498 respiratory hospital admissions in Beijing from 1st January 2016 to 31st December 2019. We employed conditional logistic regression, adjusting for meteorological conditions, holidays and influenza, to calculate percent change of hospitalization risk. Subsequently, we performed subgroup analysis to investigate potential effect modifications using a two-sample z test. Every 10 μg/m3 increase in PM2.5, PM10, NO2, SO2, and O3 led to increases of 0.26% (95%CI: 0.17%, 0.35%), 0.15% (95%CI: 0.09%, 0.22%), 0.61% (95%CI: 0.44%, 0.77%), 1.72% (95%CI: 1.24%, 2.21%), and 0.32% (95%CI: 0.20%, 0.43%) in admissions, respectively. Also, a 1 mg/m3 increase in CO levels resulted in a 2.50% (95%CI: 1.96%, 3.04%) rise in admissions. The links with NO2 (p < 0.001), SO2 (p < 0.001), O3 (during the warm season, p < 0.001), and CO (p < 0.001) were significantly weaker among patients residing in areas with higher levels of greenness. No significant modifying role of GDP was observed. Greenness can help mitigate the effects of air pollutants, while the role of GDP needs further investigation.

    微塑料(MP)污染正在发展成为全球最紧迫的环境问题之一。这项研究评估了经济活动对中国北方17个特大城市大气MP污染的影响,分析大气MPs沉积通量与城市人口等变量之间的相关性,国内生产总值(GDP),和产业结构。结果表明,MP污染明显受到与GDP增长相关的人类活动的影响,人口,以及第三产业,其中MP污染与GDP增长关系最为密切。聚丙烯,聚酰胺,聚氨酯,和聚乙烯被确定为大气MPs的主要成分。大气降尘中MPs的平均粒径为78.3µm,并且MP颗粒的频率随着颗粒尺寸的减小而增加。研究结果强调了社会经济发展与大气MP积累之间的复杂关系,为制定有针对性的减排战略提供必要的见解。
    Microplastic (MP) pollution is evolving into one of the most pressing environmental concerns worldwide. This study assessed the impact of economic activities on atmospheric MP pollution across 17 megacities in northern China, analyzing the correlation between the deposition flux of atmospheric MPs and variables such as city population, gross domestic product (GDP), and industrial structure. The results have shown that the MP pollution is obviously impacted by human activities related to increased GDP, population, as well as tertiary service sector, in which the MP pollution shows most close relationship with the GDP growth. Polypropylene, polyamide, polyurethane, and polyethylene were identified as the primary components of atmospheric MPs. The average particle size of MPs in atmospheric dustfall is 78.3 µm, and the frequency of MP particles increases as the particle size decreases. The findings highlight the complex relationship between socio-economic development and atmospheric MP accumulation, providing essential insights for the formulation of targeted emission reduction strategies.

    预期寿命可以反映气候政策的健康益处和实施成本。然而,文献中很少有研究量化预期寿命与气候政策之间的关系。在本文中,我们试图通过研究预期寿命与中国全国排放交易计划(CNETS)的关系来缩小研究差距。为了实现这一研究目标,采用可计算一般均衡(CGE)模型来模拟经济系统的运行和减排的政策冲击。CGE模型结果表明,预期寿命因GDP而延长,但因排放而缩短,GDP对预期寿命的影响大于排放影响。气候政策对预期寿命有双重影响,因为它既减轻了排放的负面影响,也减轻了GDP对寿命的积极影响;它对预期寿命的净影响是积极的。预期寿命对GDP有积极影响,这种影响受到气候政策的缓和;具体地说,气候政策加强了预期寿命对GDP的积极影响。在气候政策实施期间,预期寿命对碳排放的影响最小;换句话说,它对减排的影响最小。这些发现意味着气候政策和预期寿命是相辅相成的;政府可以实施气候政策来延长寿命或延长预期寿命,以促进政策实施。
    Life expectancy can reflect both health benefit and implementation cost of climate policy. Nevertheless, little research has quantified the relation between life expectancy and climate policy in literature. In this paper, we attempt to narrow the research gap by studying how life expectancy is related to the Chinese nationwide emission trading scheme (CNETS). To achieve this research target, a Computable General Equilibrium (CGE) model is employed to simulate the operation of the economic system and the policy shock from emission abatement. The CGE model results show that life expectancy is prolonged by GDP but shortened by emissions, and the GDP impact on life expectancy is larger than the emission impact. Climate policy has dual effects on life expectancy because it relieves both negative emission impacts and positive GDP impacts on lifespan; its net effect on life expectancy is positive. Life expectancy positively impacts GDP, and this impact is moderated by climate policy; specifically, climate policy reinforces the positive impact of life expectancy on GDP. Life expectancy minimally affects carbon emissions during climate policy implementation; in other words, it has minimal impacts on emission abatement. These findings imply that climate policy and life expectancy complement each other; the government could implement climate policy to increase lifespan or prolong life expectancy to facilitate policy implementation.

    近年来,不断增加的二氧化碳(CO2)排放量和人类活动对环境的其他负面影响引起了人们对地球未来的担忧。快速工业化,城市化,经济活动显示二氧化碳排放量激增,导致全球变暖和气候变化。这项研究的主要目的是研究诸如国内生产总值,国内生产总值平方,外国直接投资,环境外交,环境外交安全,和可再生能源消费对环境退化的影响。本研究使用1991年至2020年的面板数据计量经济学方法,为OECD国家的环境外交提供了新的视角。它有助于我们了解环境和经济因素在减少二氧化碳排放中的作用。面板数据也通过CD分析,CIPS,FMOLS,娃娃,和PMG-ARDL测试。然而,根据这项研究的结果,所有因素都显著影响环境退化(Co2排放)。通过这种方法,可以在经合组织国家的框架内找到数据来确认或否认环境库兹涅茨曲线理论的有效性。该政策框架试图通过强调合作与可持续性并将环境因素纳入经合组织国家的经济决策过程来解决环境外交与经济关切之间的问题。
    In recent years, rising carbon dioxide (CO2) emissions and other negative environmental effects of human activity have raised concerns about the planet\'s future. Rapid industrialization, urbanization, and economic activity have shown a surge in CO2 emissions, contributing to global warming and climate change. The main purpose of this study is to examine the impact of such as gross domestic product, gross domestic product square, foreign direct investment, environmental diplomacy, environmental diplomacy security, and renewable energy consumption on environmental degradation. This study provides a new perspective on environmental diplomacy in OECD countries using panel data econometric methodologies from 1991 to 2020. It contributes to our understanding of the role of environmental and economic factors in reducing CO2 emissions. The panel data is also analyzed by CD, CIPS, FMOLS, DOLS, and PMG-ARDL tests. However, as per the findings of this research, all the factors significantly impact environmental degradation (Co2 emission). Finding data to either confirm or deny the efficacy of the Environmental Kuznets Curve theory within the framework of OECD countries is possible through this approach. This policy framework attempts to solve the issues at the connection of environmental diplomacy and economic concerns by emphasizing cooperation and sustainability and incorporating environmental considerations into economic decision-making processes in OECD countries.

    Transportation energy demand has a significant impact on worldwide energy consumption and greenhouse gas emissions. Accurate transportation energy demand predictions can help policymakers develop and implement successful energy policies and strategies. In this study, a novel approach to predict transportation energy demand using the Artificial Neural Network (ANN) based on the Improved Red Fox Optimizer (IRFO) has been suggested. The proposed method utilizes the ANN model to solve the complex nonlinear relationships between transportation energy demand and its effective parameters including Gross Domestic Product (GDP), population, and vehicle numbers. Also, the IRFO algorithm was utilized to modify the ANN model\'s parameters to improve the prediction accuracy. The experimental findings demonstrate the ANN-IRFO model performs better than the other method in terms of accuracy and effectiveness. It predicts the growth of GDP, population, and vehicles number by 5.5 %, 4.8 %, and 4.2 %, respectively. The findings demonstrate that the suggested method can provide accurate forecasts for transportation energy demand, which can help decision-makers to make informed decisions and policies regarding energy management and sustainability.

    了解2004-2021年我国淋病流行趋势,预测淋病患病率,为淋病的监测和管理提供基础理论和数据支持。通过中国公共卫生科学数据中心和国家疾病预防控制局收集2004-2021年中国淋病发病率数据,并对其发病率和流行病学特征进行分析。使用Joinpoint和自回归积分移动平均(ARIMA)模型进行统计分析。使用线性相关模型分析国内生产总值(GDP)与发病率之间的相关性。2004年至2021年,中国共报告淋病2,289,435例,报告的平均发病率为9.46/10万人,下降后呈上升趋势。淋病患者主要是20-30岁,2004年至2018年,1,034,847例(53.38%)。10~20岁年龄组发病率升高趋势最为明显(2004年5811例,2018年12752例,AAPC=6.1,P<.001)。2004-2021年我国淋病发病率与GDP呈负相关(r=-0.547,P=0.019)。2012-2018年各地区平均发病率增长率与地区GDP平均增长率的相关系数为0.673(P<0.01)。ARIMA模型的均方根误差(RMSE)为4.89%,表现出强大的性能。根据模型预测,2023年将有97,910例淋病病例。
    To understand the epidemiological trend of gonorrhea in China from 2004 to 2021, predict the prevalence of the disease, and provide basic theory and data support for monitoring and managing gonorrhea. Gonorrhea incidence data in China from 2004 to 2021 were collected through the China Public Health Science Data Center and National Administration of Disease Prevention and Control, and the incidence and epidemiological characteristics were analyzed. Statistical analysis was performed using Joinpoint and autoregressive integrated moving average (ARIMA) models. A linear correlation model was used to analyze the correlation between gross domestic product (GDP) and the incidence rate. From 2004 to 2021, a total of 2,289,435 cases of gonorrhea were reported in China, with an average reported incidence rate of 9.46/100,000 people and a downward followed by an upward trend. Individuals with gonorrhea were primarily 20-30 y of age, with 1,034,847 cases (53.38%) from 2004 to 2018. The trend of increasing incidence was most obvious in the 10-20 age group (5,811 cases in 2004 to 12,752 cases in 2018, AAPC = 6.1, P < .001). The incidence of gonorrhea in China was negatively correlated with GDP from 2004 to 2021 (r = -0.547, P = .019). The correlation coefficient between the average incidence growth rate of each region from 2012 to 2018 and the average growth rate of regional GDP was 0.673 (P < .01). The root mean square error (RMSE) of the ARIMA model was 4.89%, showing powerful performance. There would be 97,910 gonorrhea cases in 2023 as predicted by the model.

    How do digitalizing businesses help them achieve sustainable growth? This research examines the mediating function of green technology innovation in answering this question by defining sustainable development performance in terms of corporations\' financial and environmental success. The educational system in China is examined to see how much of an impact it has on eco-innovation, as well as the relationship between green technology and innovation. The IFE test was utilized to determine whether or not the associations between variables such as GDP per capita, urbanization, green technology, higher education, and carbon dioxide emissions will continue to exist between 2004 and 2020 in China. The data for this analysis came from 30 of China\'s provinces. The findings of both the short-term and long-term CS-ARDL estimations demonstrated a positive link between eco-innovation and GDP per capita, green technology, higher education, and CO2 emissions. On the other hand, a negative correlation was found between urbanization and eco-innovation. The next topic covered in the research was how the effects of green technology might be seen in areas such as GDP per capita, higher education, and carbon dioxide emissions. The findings might provide valuable knowledge that developing economies can use to construct a feasible, sustainable path.
