试论突发群体事件中的谣言危机管理

十年前,在中国还很少有人谈起"突发群体事件"这一概念,而当今有越来越多的人时常谈起,各种研究层出不穷,这是因为,近年来不仅一般性突发事件频繁发生,而且群体性事件也日益增长.通过时这类事件的观察分析,可以得出,只要发生突发群体事件,就伴随有谣言的产生.如果对谣言进行有效的危机管理,可以减轻此类事件的严重程度,因此本文对突发群体事件的谣言危机管理进行研究.

生态系统服务价值评估的研究综述

生态系统服务是人类可持续发展的物质基础和自然资本.对生态系统服务价值的评估有利于人们认识自然生态系统对人类福利的重要性,是生态学、地理学等自然科学利用经济学方法进一步影响社会决策的尝试.但由于生态系统的复杂性和经济系统对生态系统服务反映的模糊性,目前尚难准确评估生态系统服务价值.多尺度综合研究与动态参与式评估、物产价值与非物质性服务价值的分离研究、对边际价值的调查与模拟研究、与生态补偿等相关领域的结合研究、非物质性服务价值的市场化研究等是生态系统服务价值评估研究的深化方向.

四川省湿地生态系统服务功能价值评估

依据<中国湿地百科全书>及四川省林业厅调查数据,将四川省湿地类型划分为河流湿地、湖泊湿地、沼泽和沼泽化草地、水田湿地、池塘湿地、水库湿地两大类6种类型,采用定量货币化方法对四川省湿地生态系统服务功能价值进行了估算,为四川省湿地保护与规划提供生态经济理论依据.结果表明,四川省湿地生态服务功能的总价值达7 483.03亿元人民币,相当于四川省2009年GDP的52.88%,各项湿地生态功能价值中最高的是固碳释氧功能价值达3 422.00亿元人民币,约占45.73﹪,其次是水分调节功能和物质生产功能,说明湿地对四川省的生态环境和国民经济有重要作用,并和人们的生产、生活、娱乐密切相关.     

Grid-Enabled Simulation-Optimization Framework for Environmental Characterization

Many engineering and environmental problems that involve the determination of unknown system characteristics from observation data can be categorized as inverse problems. A common approach undertaken to solve such problems is the simulation-optimization approach where simulation models are coupled with optimization or search methods. Simulation-optimization approaches, particularly in environmental characterization involving natural systems, are computationally expensive due to the complex three-dimensional simulation models required to represent these systems and the large number of such simulations involved. Emerging grid computing environments (e.g., TeraGrid) show promise for improving the computational tractability of these approaches. However, harnessing grid resources for most computational applications is a nontrivial problem due to the complex hierarchy of heterogeneous and geographically distributed resources involved in a grid. This paper reports and discusses the development and evaluation of a grid-enabled simulation-optimization framework for solving environmental characterization problems. The framework is designed in a modular fashion that simplifies coupling with simulation model executables, allowing application of simulation-optimization approaches across problem domains. The framework architecture utilizes standard communications protocols and the message passing interface with an application programming interface to establish a connection between a centralized search application and simulation models running on TeraGrid resources. Sets of performance and scalability results for solving a groundwater source history reconstruction (SHR) problem are presented. The results show that for a given set of resources, parameters controlling the granularity at various levels of parallelism play an important role in the overall parallel performance. A production run for solving the SHR problem using three geographically distributed grid resources indicates that even in a cross-site grid environment a factor of 90 speedup is possible using 140 computer processors.     

Integrated Framework to Investigate Value Innovations

A conceptual framework has been developed to investigate value innovations within construction companies. A visual metaphor has been defined to model the innovation system where the elements of the model are objectives, strategies, environmental barriers/drivers, and organizational factors. The major idea is that none of the elements of the model alone can explain the innovative capability, and elements as well as their interrelations should be considered concurrently to investigate how the innovation system works in construction companies. An application of the framework has been demonstrated by 11 cases taken from the Turkish construction industry. General findings of the research have been reported as well as specific company examples that demonstrate the major mechanisms of the innovation system. The research findings have revealed that environmental factors can have both hindering and supporting impacts on the innovation system, depending on other elements of the framework. The type of innovations is strongly related to company targets, strategies, strengths/weaknesses, and environmental factors. Moreover, matching of appropriate strategies with organizational properties leads to an increase in innovative capacity.     

Environmental Assessment of Logistics Outsourcing

Environmental awareness is increasingly important to society, government, and industry, and there is a strong demand for sustainable development practices. The importance of supply chain management is critical, as it characterizes and influences the life cycles of all products. Within the major logistics trends, outsourcing has a significant potential to increase sustainability in the supply chain as third-party logistics providers (3PLs) focus on improving resource utilization and making processes more efficient. However, their motivation is largely economic, and an environmental perspective is rarely seen in 3PLs. As consumers demand greener alternatives and, subsequently, environmental regulatory measures are implemented, 3PLs will have to become more environmentally and socially aware in order to develop sustainability goals. This study compares two scenarios using life-cycle assessment (LCA): one where logistics functions are handled in-house, and an alternative scenario where such functions are outsourced to a 3PL. The impacts of logistics outsourcing on energy utilization, global warming potential, and fatalities are first quantified in the supply chain of an automobile. Even though vehicle operation, responsible for most of the impacts considered, is outside the domain of logistics functions, logistics outsourcing nonetheless has the potential to reduce energy use and global warming potential by 0.4–2% and fatalities by 0.8–3.3% throughout the entire life cycle of a typical automobile. Road and air transportation are found to account for most of the impacts in all selected metrics. Analyzing logistics outsourcing in the other sectors of the U.S. economy revealed the same trend as observed in the supply chain of an automobile.
