AHP-based Landscape Value Evaluation of Perennial Flower Border Application in Hefei City

An analytic hierarchy process(AHP)was employed to establish a landscape value evaluation model for 20 common species of perennial flowers in the flower border of Hefei City.With the overarching objective of determining the application value of the flower border,10 evaluation factors were identified and subsequently classified into 3 distinct grades.Grade I(L>2.5)was defined as perennial flower resources with the highest development and utilization value,including only one species of Salvia farinacea.Grade II(2.0≤L≤2.5)was defined as perennial flower varieties suitable for most areas,encompassing 9 species of plants,such asTaraxacummongolicum.Grade III(L<2.0)was defined as perennial flower varieties with low application value,encompassing 10 species of plants,such asRuellia brittoniana,but lacking the value of further popularization and application.Consequently,the proportion of their application in the flower border should be reduced.The evaluation results can serve as a theoretical foundation for the implementation of perennial flowers in urban flower borders.

Cross-border E-commerce Accelerates Diversely Abroad

“Strength”and“vitality”are the comments that people in the industry have used to describe China’s cross-border e-commerce in 2023,which has been proven by the latest statistics.According to the General Administration of Customs,in 2023,the total volume of imports and exports was RMB 2.38 trillion,up by 15.6%.The volume of exports was RMB 1.83 billion,up by 19.6%,and the volume of imports was RMB 548.3 billion,up by 3.9%.

Border effects of the main and ratoon crops in the rice ratooning system

The border effect(BE)is widely observed in crop field experiments,and it has been extensively studied in many crops.However,only limited attention has been paid to the BE of ratoon rice.We conducted field experiments on ratoon rice in Qichun County,Hubei Province,Central China in 2018 and 2019 to compare the BE in the main and ratoon crops,and to quantify the contribution of BE in the main crop to that in the ratoon crop.The BE of two hybrid varieties was measured for the outermost,second outermost,and third outermost rows in each plot of both crops.To determine the contribution of BE between the two crops,portions of hills in the outermost and second outermost rows were uprooted during the harvest of the main crop so that the second and third outermost rows then became the outermost rows in the ratoon crop.Overall,the BE on grain yield was greater in the main crop than in the ratoon crop.In the main crop,the BE on grain yield was 98.3%in the outermost row,which was explained by the BE on panicles m^(–2),spikelets/panicle,spikelets m^(–2),and total dry weight.In the ratoon crop,the BE on grain yield was reduced to 60.9 and 27.6%with and without the contribution of the BE in the main crop,respectively.Consequently,55.1%of the BE on grain yield in the ratoon crop was contributed from the main crop.High stubble dry weight and non-structural carbohydrate(NSC)accumulation at the harvest of the main crop were responsible for the contribution of BE in the main crop to that in the ratoon crop.Our results suggest that increases in stubble dry weight and NSC accumulation at the harvest of the main crop could be important strategies for developing high-yielding cropping practices in the rice ratooning system.

A multi-UAV deployment method for border patrolling based on Stackelberg game

To strengthen border patrol measures, unmanned aerial vehicles(UAVs) are gradually used in many countries to detect illegal entries on borders. However, how to efficiently deploy limited UAVs to patrol on borders of large areas remains challenging. In this paper, we first model the problem of deploying UAVs for border patrol as a Stackelberg game. Two players are considered in this game: The border patrol agency is the leader,who optimizes the patrol path of UAVs to detect the illegal immigrant. The illegal immigrant is the follower, who selects a certain area of the border to pass through at a certain time after observing the leader’s strategy. Second, a compact linear programming problem is proposed to tackle the exponential growth of the number of leader’s strategies. Third, a method is proposed to reduce the size of the strategy space of the follower. Then, we provide some theoretic results to present the effect of parameters of the model on leader’s utilities. Experimental results demonstrate the positive effect of limited starting and ending areas of UAV’s patrolling conditions and multiple patrolling altitudes on the leader ’s utility, and show that the proposed solution outperforms two conventional patrol strategies and has strong robustness.

Progress of Central Bank Digital Currency in Cross-border Payments and the Application Prospect in the Oil and Gas Field

The rapid development of the digital economy and profound changes in currency functions have driven the emergence of a large number of digital currencies.In order to improve the competitiveness and efficiency of payment systems,governments all over the world have accelerated the research and development of central bank digital currency(CBDC).After years of preparation and research and development,Digital renminbi has also entered the pilot application stage.Given the many shortcomings of the current cross-border payment system,CBDC cross-border payment has become an important development direction.At present,some central banks are collaborating on CBDC cross-border payment research and initiating experimental plans to explore CBDC cross-border payment arrangements.With the expansion of the acceptance range of Digital renminbi and the improvement of the international use level of CNY,oil and gas enterprises will have broad prospects in the cross-border payment field in the future.This paper suggests that oil and gas enterprises,in accordance with the principle of"from easy to difficult,step by step",give priority to the introduction of Digital renminbi from regions and fields where RMB or local currency settlement has been achieved,and combine Digital renminbi with imported oil and gas to explore the use of Digital renminbi in cross-border payment.

多情景模拟下的跨境铁路运输时效研究——以中老铁路为例

跨境铁路运输是中国与周边国家陆路联通的重要环节。跨境铁路运输时效既受线路畅通情况、基础设施技术等级等“硬联通”因素的制约,也受到海关条例、口岸畅通水平等“软联通”因素的影响。因此,跨境铁路运输时效研究应充分考虑不同情景,以期更科学地模拟运输时长的变化机理。本文以中老铁路(中国昆明−老挝万象,简称中老铁路)为例,在梳理中老铁路沿线地区社会经济概况及基础设施发展水平的基础上,考虑不同运营速度、通关时间、铁轨换装、多式联运等因素,构建了长途跨境运输时间的计算模型,采用多情景模拟方法,解析了中老铁路运的优势距离及客货运时效变化。研究表明:①中老铁路有助于沿线跨境运输时间显著减少。相比公路运输,客货运时间优势均超过20%;②通关时间是影响跨境铁路运输的关键要素之一,占运输总时长的20%~60%;③铁海联运是中老铁路运输进一步提升运输效率的途径,能有效缩短老挝至日本的总运输时间。

教师的教育判断力:内涵要义、价值表征及发展策略

教育是中国式现代化的关键组成,面对教育的快速发展以及教育数字化、人工智能的到来,教育判断力是教师减少迷茫、寻求立命之所的重要支点,也是提升教师教育质量的关键。教师的教育判断力就是在教育情境中合目的性的指向下,将各种教育现象、事例与一般规则交互作用而进行的“归摄”“运用”“反思”的判断能力,它是教育“尝试”与“提升”特质的诉求、教育思想形成与创生的支撑、教师生命意义获得与更新的助力。然而,当下教师的教育判断力面临缺乏生长土壤、教师教育者的判断力不足等困境。提升教师的教育判断力,应以深度学习为理念,以案例教学为依托,以教育情景为中介,建立跨界教师教育师资团队。

从“数据隐私框架”看欧美数据跨境流动的规则博弈

欧美《隐私盾协议》失效后,双方为了恢复数据跨境流动秩序,于2022年底达成了“数据隐私框架”。该框架旨在回应欧盟法院在“《隐私盾协议》无效案”中提出的主要关切。2023年7月,欧盟委员会基于该框架对美国的个人数据保护水平发布了充分性认定决议。然而,该框架并未对美国情报机构大规模收集数据与窥探隐私的行为施加实质性限制。此外,框架建立的双层救济机制由于缺乏独立性,也无法给数据隐私权益受损的欧盟公民提供充分有效的救济。与《隐私盾协议》相比,该框架在本质上并没有明显的突破。欧盟和美国在双方数据跨境流动制度安排上的博弈,表面上是两种数据保护理念和治理模式的碰撞,实际上反映出了欧盟实施“数字主权”战略与美国维护“数字霸权”地位之间存在的根本利益冲突。欧美凭借各自优势,在数字经济时代争夺全球数字治理话语权。通过深入研究欧美之间关于“数据隐私框架”的规则博弈,可以为我国在选择适合本土的数据监管模式和提升数据治理规则话语权方面提供重要的思考和启示。

食品安全风险伤害与风险交流对消费者风险感知的综合影响——以跨境电商为例

探讨消费者食品安全风险感知形成机理并科学引导,对推动我国食品产业高质量发展具有重要作用。区别于以往单一维度的研究,从风险的客观存在与主观构建的二重性出发,以跨境电商为研究情境探讨食品安全风险场域(风险伤害与风险交流)对消费者风险感知的影响机制。实验结果表明:食品安全风险场域显著影响消费者风险感知,相较于风险伤害,风险交流对消费者风险感知的影响更为显著,且在女性群体和含低龄人口或高龄人口的家庭中更为显著。食品安全关注度在风险场域影响消费者风险感知的路径中发挥“遮掩效应”;平台情境在风险场域与食品安全关注度的因果关系间起负向调节效应。
