中国“碳中和”目标的实现路径与模式选择

围绕中国碳中和目标的实现路径与模式选择问题，提出了一个中国应对气候变化整体治理模式，即多阶段混合主导型碳中和实现模式。这一模式是以国家为核心，在一定时期和内外环境约束下，通过减排和增汇路径，对中国境内由人类活动造成的CO2排放与人为CO2吸收量之间关系进行调整和平衡的过程；其内部由宏观、中观和微观三层结构组成，每层结构各不相同。多阶段混合主导型碳中和实现模式的提出，拓展和完善了气候变化整体治理理论，为气候变化治理提供了机制借鉴。     

Nature and social work pedagogy: How U.S. social work educators are integrating issues of the natural environment into their teaching

ABSTRACT

The article presents a study of how U.S. social work educators are including discussion, exercises, readings, and other pedagogical approaches to the natural environment into their classrooms. The findings are part of a larger, naturalistic study that gathered data using a semi-structured interview format. The three major themes that emerged were human behavior theory, ecological and environmental justice, and environmental sustainability. The participants are introducing issues of the natural environment using varied pedagogical techniques including readings, in-class discussions and exercises, service learning, assignments, including written and practical work, research, self-awareness exercises, and class facilitation. Questions for further investigation of social work and the natural environment are included.     

An Optimization‐Based Framework for the Identification of Vulnerabilities in Electric Power Grids Exposed to Natural Hazards

This article proposes a novel mathematical optimization framework for the identification of the vulnerabilities of electric power infrastructure systems (which is a paramount example of critical infrastructure) due to natural hazards. In this framework, the potential impacts of a specific natural hazard on an infrastructure are first evaluated in terms of failure and recovery probabilities of system components. Then, these are fed into a bi‐level attacker–defender interdiction model to determine the critical components whose failures lead to the largest system functionality loss. The proposed framework bridges the gap between the difficulties of accurately predicting the hazard information in classical probability‐based analyses and the over conservatism of the pure attacker–defender interdiction models. Mathematically, the proposed model configures a bi‐level max‐min mixed integer linear programming (MILP) that is challenging to solve. For its solution, the problem is casted into an equivalent one‐level MILP that can be solved by efficient global solvers. The approach is applied to a case study concerning the vulnerability identification of the georeferenced RTS24 test system under simulated wind storms. The numerical results demonstrate the effectiveness of the proposed framework for identifying critical locations under multiple hazard events and, thus, for providing a useful tool to help decisionmakers in making more‐informed prehazard preparation decisions.     

挣脱生态牢笼的路径探幽——《共产党宣言》中马克思生态思想解读

《共产党宣言》蕴含着深刻的生态思想,其体系以人、社会、自然整体为背景,其核心观点认为生态问题是由资本主义生产方式引起的.马克思在唯物史观视野下,科学论证了资产阶级的所有制必然灭亡、共产主义必然实现的历史发展逻辑,廓清了人与人、人与自然之间双重和解的演化路径.其中关于科技提升、市场拓展、交通和通信发展等引起世界市场“生态扩张”的思想,对全球化程度日益加深境况下“生态文明”和“人类命运共同体”的构建具有重大的理论和实践指导价值.     

Language roulette – the effect of random placement on refugees’ labour market integration

Placement of refugees and subsequent labour market integration within a host country represents a key challenge for policymakers and has emerged as one of the most divisive topics in the public debate. Immigration policy in Switzerland adopts random placement of asylum seekers across its different language regions. Hence, this policy allows to estimate the causal effect of language skills on employment chances, as refugees are exogenously placed across regions where the spoken language could either match or deviate from individual language skills. The results of this ‘natural experiment’ indicate substantially higher probabilities of finding employment when asylum seekers are placed in regions with a lingua franca that matches their individual language skills. Additionally, the findings suggest that language course participation can offset the reduced likelihood of employment in cases of a language mismatch. While random placement of refugees may be desirable for political reasons, it is detrimental to the economic integration process. Thereby, the study draws relevant conclusions for a larger European immigration policy.     

区块链应用下生态农产品供应链优化

利用博弈模型，对生态农产品供应链内部契约合作稳定情况进行研究，并就区块链技术如何保障生态农产品供应链稳定运行进行分析。分析认为：生态农产品供应链稳定运行情况受到市场风险制约，区块链技术能通过改善生态农产品供应链内部信息不对称现象，增加生态农产品供应链内部交易节省成本并提高主体违约成本，同时增加生态农产品供应链主体长期合作得益及协调主体合作，从而保障生态农产品供应链稳定运行。在此基础上，结合区块链技术特征对区块链技术应用下生态农产品供应链结构设计进行了探讨并对部分可能出现的问题进行了讨论。     

新时代中国美丽乡村建设的思维引领

中国特色社会主义进入新时代，美丽中国建设迎来了新的发展机遇。美丽乡村建设作为美丽中国建设的基础和关键，既事关社会主义生态文明观的牢固树立，又事关满足人民日益增长的优美生态环境需要。为此，我们要在遵循建设美丽中国基本原则的基础上，努力强化美丽乡村建设的思维引领。这就要坚持以战略思维完善顶层设计，以创新思维激发内生动力，以辩证思维推动协同治理，以法治思维强化刚性约束，以底线思维恪守生态红线，把党在美丽乡村建设过程中总揽全局、协调各方的领导作用落到实处，进而开辟社会主义中国乡村生态文明新时代。     

Media Disaster Reporting Effects on Public Risk Perception and Response to Escalating Tornado Warnings: A Natural Experiment

Previous research has evaluated public risk perception and response to a natural hazards in various settings; however, most of these studies were conducted either with a single scenario or after a natural disaster struck. To better understand the dynamic relationships among affect, risk perception, and behavioral intentions related to natural disasters, the current study implements a simulation scenario with escalating weather intensity, and includes a natural experiment allowing comparison of public response before and after a severe tornado event with extensive coverage by the national media. The current study also manipulated the display of warning information, and investigated whether the warning system display format influences public response. Results indicate that (1) affect, risk perception, and behavioral intention escalated as weather conditions deteriorated, (2) responses at previous stages predicted responses at subsequent stages of storm progression, and (3) negative affect predicted risk perception. Moreover, risk perception and behavioral intention were heightened after exposure to the media coverage of an actual tornado disaster. However, the display format manipulation did not influence behavioral responses. The current study provides insight regarding public perception of predisaster warnings and the influence of exposure to media coverage of an actual disaster event.     

社会性别视角下少数民族妇女在边疆生态治理中的作用分析——基于对怒江傈僳族的调查
