Is being a leader a mixed blessing? A dual‐pathway model linking leadership role occupancy to well‐being

Recent leadership research has drawn greater attention to how the well‐being of leaders influences leadership behaviors, follower performance and well‐being, and overall leadership effectiveness. Yet little attention has been paid to the relationship between occupying leadership positions and job incumbents' well‐being. This research addresses this question by developing and testing a dual‐pathway model. Our model proposes that incumbency in leadership positions is positively related to high levels of both job demands and job control, whereas job demands and job control have offsetting effects on well‐being. Results based on a longitudinal sample revealed that employees who transitioned from nonleadership positions to leadership roles showed trajectories of increasing job demands and job control, whereas such trends were weaker among those who remained in nonleadership positions. Findings from three additional samples generally demonstrated that leadership role occupancy was indirectly related to various indices of psychological and physiological well‐being through job demands and job control. Because the signs of the indirect effects through job demands and job control differed in expected ways, the overall relationship between leadership role occupancy and the well‐being outcomes was generally small and nonsignificant. We discuss research and practical implications of our framework and findings for organizations, employees, and leaders.     

States,coalitions, and the legalization of the global climate regime: negotiations on the post-2020 architecture

Why do some states and state coalitions, acting within the United Nations Framework Convention on Climate Change (UNFCCC), support harder legalization of the global climate regime? In order to explain why, the effects of four causal factors are considered: climate vulnerability, the emission intensity of the national economy, a state’s power position, and socialization into climate norms. To identify the legalization positions of UNFCCC actors, an original content analysis is conducted of all the submission and meeting statements made at the Ad Hoc Working Group on the Durban Platform during the years 2012–2015. Subsequently, a qualitative comparative analysis is carried out to find out which combinations of the causal factors offer a sufficient explanation for the analyzed outcome, leading to the identification of two causal pathways that lead states to endorse harder legalization of the climate regime.     

切尔诺贝利核电站事故后果模式估算国际比对

介绍我国参加国际原子能机构（IAEA）组织的“切尔诺贝利核电站事故后果模式估算国际比对”中采用的模式及其估算结果与实测值以及与其地各国估算结果的比较。提出土壤表面沉积量与农作物可食部分核素浓度估算模式（属半动态模式,其余模式采用国内通用的静态模式）。比较结果表明,对事故后当年的浓度预测结果与实测值符合较好,对事故后第２年及更长时间的预测结果明显偏高,有待改进。     

国际碳排放权交易模式的更替发展与协同优化路径

实现碳中和是各国应对气候变化的共同选择。碳市场作为以碳排放权交易为核心的市场机制是加速全球碳排放目标实现的重要途径之一。尽管当前全球碳市场的发展仍呈现区域性和碎片化状态,但随着能源危机的加剧,极端气候灾难的不确定性增多,未来通过碳市场领域的国际合作实现全球碳市场的协同以应对气候变化仍是大势所趋。本文试图通过对国际碳市场进行回顾和类型化总结,并就《巴黎协定》下国际碳交易模式的协同困境从技术、制度和参与程度三个维度开展分析。作者认为,如欲加快全球碳交易的协同进程,应尽快完善国际碳交易中的技术适用细节,提升碳交易相关制度的适用力度,扩大碳交易相关制度的适用范围,加强发展中国家的碳市场的基础建设,拓展发展中国家碳交易市场建设支持来源,最终建立全球碳价格统一机制。提前布局研究碳市场的跨境连接方案对于中国而言极具现实意义,本文最后对中国参与全球碳交易市场的国际合作前景作出了展望。     

Climate change and disaster management

Climate change, although a natural phenomenon, is accelerated by human activities. Disaster policy response to climate change is dependent on a number of factors, such as readiness to accept the reality of climate change, institutions and capacity, as well as willingness to embed climate change risk assessment and management in development strategies. These conditions do not yet exist universally. A focus that neglects to enhance capacity-building and resilience as a prerequisite for managing climate change risks will, in all likelihood, do little to reduce vulnerability to those risks. Reducing vulnerability is a key aspect of reducing climate change risk. To do so requires a new approach to climate change risk and a change in institutional structures and relationships. A focus on development that neglects to enhance governance and resilience as a prerequisite for managing climate change risks will, in all likelihood, do little to reduce vulnerability to those risks.     

Disaster risk, climate change and international development: scope for, and challenges to, integration

Reducing losses to weather-related disasters, meeting the Millennium Development Goals and wider human development objectives, and implementing a successful response to climate change are aims that can only be accomplished if they are undertaken in an integrated manner. Currently, policy responses to address each of these independently may be redundant or, at worst, conflicting. We believe that this conflict can be attributed primarily to a lack of interaction and institutional overlap among the three communities of practice. Differences in language, method and political relevance may also contribute to the intellectual divide. Thus, this paper seeks to review the theoretical and policy linkages among disaster risk reduction, climate change and development. It finds that not only does action within one realm affect capacity for action in the others, but also that there is much that can be learnt and shared between realms in order to ensure a move towards a path of integrated and more sustainable development.     

Transboundary River Floods and Institutional Capacity1

Abstract: While transboundary flood events have become more frequent on a global scale the past two decades, they appear to be overlooked in the international river basin (IRB) cooperation and management arena. The present study therefore combined geopolitical measures with biophysical and socioeconomic variables in an attempt to identify the IRBs with adequate institutional capacity for management of transboundary floods. It also classified basins that would possibly benefit from enlarging the institutional capacity related to transboundary floods. Of the 279 known IRBs, only 78 were represented by a transboundary rivers institution. A mere eight of the 153 identified institutions had transboundary flooding listed as an issue in their mandate. Overall, 43 basins, where transboundary floods were frequent during the period 1985‐2005, had no institutional capacity for IRBs. The average death and displacement tolls were found to be lower in the 37 basins with institutional capacity, even though these basins experienced twice as much transboundary floods with significant higher magnitudes than those in basins without institutional capacity. Overall, the results suggested that institutional capacity plays a role in the reduction of flood‐related casualties and affected individuals. River basins such as the Juba‐Shibeli, Han, Kura‐Araks, Ma, Maritsa, Po, Coco/Segovia, Grijalva, Artibonite, Changuinola, Coatan Achute, and Orinoco experienced more than one transboundary river flood, but have not yet set up any institutions for such events, or signed any appropriate treaties focused on floods. These basins were therefore recommended to consider focusing attention on this apparent lack of institutional capacity when it comes to managing transboundary flood events.     

中国国际河流水资源利用立法略论

我国的国际河流数量众多,分布广泛。国际河流的利用主要分为国际河流的航行利用和国际河流的水资源利用2个方面。我国对国际河流的利用主要表现为对国际河流水资源的利用。完善我国国际河流水资源利用立法非常重要。它可以确保我国既充分、合理,又合法、有据地利用国际河流水资源,消除国际舆论中“中国水威胁论”的不良影响;缓解国内水资源日益紧张的局面;发展流域经济;保护当地生态环境。运用综合分析和实证研究的方法,对我国国际河流水资源利用立法情况和对外谈判进行探讨。检视我国国际河流水资源利用立法存在诸多问题。国际河流水资源利用立法理念不协调;国际河流水资源污染防治立法视野狭隘;双边或多边区域性专项水协定缺失等问题表现得尤为突出。应采取调整国际河流水资源利用立法理念;坚持“公平利用”原则,维护我国权益;健全双边或多边的区域性专项水协定体系;拓宽立法视野,兼顾国际河流水资源利用和保育;保护国际河流水环境等措施,规制国际河流水资源的利用。
