Exploring the information literacy of professionals in safety management

With the rapid development of increasingly complex technology and large scale industrial projects, all kinds of safety problems become extremely intricate in daily safety management (SM). It is therefore indispensable to effectively collect, analyze, assess, and synthesize information that is relevant to accident risk. In this paper, the concept of the information literacy (IL) of professionals in SM is proposed, and a conceptual framework is put forward. Further, determinants of the IL of safety professionals are suggested, including individual attributes, safety climate and culture, information infrastructure, information technology (IT) human resources, production technology and management, and national information policy, law and ethics. Of course, further research on the IL of safety professionals should be carried out for effective SM.     

The nexus across water,energy and food (WEF): Learning from research,building on evidence,strengthening practice

While water-energy-food (WEF) Nexus is one of the most important, and widely investigated, environmental topics of our time, previous stock taking efforts possess notable limitations, namely (i) their focus is restricted to research articles, and (ii) there is less focus on nexus permutations that begin with energy and food. This paper assembled more than 900 documents and systematically categorized them according to more than 10 key parameters (e.g. scale, methods, limitations), to characterize approaches, achieved outcomes and presence of variables likely to support on-the-ground change. Our results reveal that WEF Nexus activities are often driven by the water sector, undertaken at global and national scale and authored by experts from diverse backgrounds. Among the utilized methods, modelling and review (i.e. systematic) are the most common. While climate change and governance are routinely considered in WEF Nexus documents, gender, stakeholders and capacity are not. These findings highlight areas for improvement in the design of WEF Nexus initiatives.

Seismic fragility analysis of a coupled tank-piping system based on artificial ground motions and surrogate modeling

The catastrophic consequences of recent NaTech events triggered by earthquakes highlighted the inadequacy of standard approaches to seismic risk assessment of chemical process plants. To date, the risk assessment of such facilities mainly relies on historical data and focuses on uncoupled process components. As a consequence, the dynamic interaction between process equipment is neglected. In response to this gap, researchers started a progressive integration of the Pacific Earthquake Engineering Research Center (PEER) Performance-Based Earthquake Engineering (PBEE) risk assessment framework. However, a few limitations still prevent a systematic implementation of this framework to chemical process plants. The most significant are: (i) the computational cost of system-level simulations accounting for coupling between process equipment; (ii) the experimental cost for component-level model validation; (iii) a reduced number of hazard-consistent site-specific ground motion records for time history analyses.In response to these challenges, this paper proposes a recently developed uncertainty quantification-based framework to perform seismic fragility assessments of chemical process plants. The framework employs three key elements: (i) a stochastic ground-motion model to supplement scarcity of real records; (ii) surrogate modeling to reduce the computational cost of system-level simulations; (iii) a component-level model validation based on cost-effective hybrid simulation tests. In order to demonstrate the potential of the framework, two fragility functions are computed for a pipe elbow of a coupled tank-piping system.     

IWRM视角下污水治理体系问题系统诊断与对策研究——以浙江省为例

基于集成水资源管理理念框架,较系统地构建了污水治理体系问题诊断指标体系并明确了诊断标准.实证研究表明,浙江省污水治理体系仍存在政策不协调,投资结构不合理,体制横向不协调、纵向不到位、职责分散,民主参与决策与监督机制不健全,排污行为监测监管不到位,经济激励不够、行业自律不足等问题.建议浙江省应进一步协调区域发展政策,优化污水治理城乡投融资结构,完善机构设置,优化部门协调,加强政府监测监管等,以提高污水治理绩效.     

水资源多目标协同配置:全价值基础上的框架研究

从资源的视角而言,水资源具有的社会、经济、生态属性中,社会属性和生态属性所提供的生态功能和服务多是外部性和非市场的,其价值在纯粹的市场驱动下难以充分实现。从资源管理视角而言,水资源多目标协同配置的实质是水资源多重属性功能和服务的均衡。因此,将具有外部性的社会、生态功能和服务与具有经济价值的功能和服务同时纳入配置框架,是实现多目标协同配置实践的关键问题。本文在回顾水资源配置和水资源非市场价值评估的相关研究的基础上,围绕我国现行水资源配置存在的主要问题,通过水资源的全价值(市场价值和非市场价值)将其多属性功能和公众意愿纳入水资源多目标协同配置中,从水资源管理信息系统、全价值评估和配置管理的绩效评价三个方面构建了水资源配置的多目标协同框架,最后提出相关的保障政策建议。     

Examining strategic sustainability plans and smart-growth land-use measures in California cities

Given many potential obstacles, what types of strategic plans and measures for climate protection and/or energy sustainability are more likely than others to be adopted by cities? What are the key internal and external obstacles to adopting and implementing these plans and measures? Based on data obtained from a survey conducted from 2010 to 2011 and other sources, this paper develops a framework derived from political contracting theory and strategic orientation literature to examine how public management obstacles, socio-economic factors, and political factors influence a city's likelihood of having strategic energy sustainability plans and measures in place. Moreover, this paper finds that many California cities remain reluctant to require residents and businesses to comply with more challenging sustainability measures, such as smart-growth land-use practices, and that those cities with a strategic energy sustainability plan already in place tend to be more willing to adopt smart-growth land-use measures.
