The reciprocal relationship between policy debate and media coverage: The case of road pricing policy in the Netherlands

This study examined the changes in the media coverage of two road pricing schemes proposed in the Netherlands in the period 1998–2010, as well as the link between the media coverage and the policy debate. Both pricing proposals were debated for several years and neither was introduced. Our findings show that space allocation for type of overall tone (e.g. negative or positive towards a pricing proposal) and the range of issues and policy actors in the media coverage were very different for the two proposals, and for each proposal fluctuated greatly over time. Our analysis suggests that such a variation in the media coverage was a reflection of changes in the content of the policy debate (e.g. caused by the specific design features of pricing proposal under discussion, the different policy actors engaged in the debate and their messages about the proposal). This indicates that policymakers can influence the media coverage of road pricing policies to some extent by managing the policy debate. Our findings also show not only that changes in the content of the policy debate were reflected in the media coverage, but also that the media coverage influenced the policy debate: the statements or actions of policy actors received media coverage, which then in turn stimulated the policy debate. However, the influence of media on the policy debate was rather indirect, in that policy actors mostly reacted to the messages from other policy actors reported in the media and to a lesser extent to the media coverage itself.     

铁路救援基地层级规划选址模型

基于中国铁路组织机构的特点和应急救援现状,提出了铁路救援基地的层级网络建设理念。分析了现有铁路救援基地多目标规划选址模型的不足,将铁路救援基地分为枢纽救援基地和快速救援基地。以最小救援基地总成本和最短救援响应时间为双目标函数,以最大服务距离为约束条件,建立了铁路救援基地多目标层级规划选址模型。采用层次分析法、灰色关联分析与线性参考技术等方法抽象模型参数,采用蚁群算法求解模型,并将计算结果与现有的救援决策方案进行对比。研究结果表明:应用提出的模型,通过抽象模型参数,可得到26个救援基地备选点、61个服务需求点与188条路径;在完全覆盖事故风险的情况下,救援基地数量减少3个,节约成本约240万元,总救援响应时间、最大平均救援响应时间和最小平均救援响应时间分别降低0.04、0.46、0.29h。     

包西铁路GSM-R数字光纤直放站方案研究

通过传输损耗、上行噪声叠加、传输时延和组网等方面来比较模拟光纤直放站和数字光纤直放站的优缺点,试验利用数字光纤直放站在既有包西线GSM-R系统中替代模拟光纤直放站进行弱场覆盖,发现数字光纤直放站近、远端机之间的光纤传输链路不受光功率衰减的影响,并能通过调整远端机时延可以良好解决实际应用中多个远端单元RRU之间重叠覆盖区域的时延色散问题,对数字光纤直放站今后在铁路推广应用具有参考价值。     

建设项目推行工程保险的障碍与对策

对推进企业补充医疗保险的思考

目前我公司系统多数企业均按属地原则参加了当地的基本医疗保险,但是在“低水平、广覆盖”的原则下,企业职工患病自付负担过重,不利于职工队伍的稳定。因此,企业需要建立补充医疗保险来解决这些问题。本文从建立补充医疗保险的必要性;如何建立补充医疗保险;建立补充医疗保险的实践;企业补充医疗保险的完善等方面进行分析,从而将建立补充医疗保险的方法、措施形成一个较为完整的体系,真正达到促进企业医疗改革,解除职工医疗后顾之忧,稳定职工队伍,对树立以人为本,构建和谐企业,增强企业凝聚力,促进企业发展起到积极作用。     

U.S. Coastal Flood Insurance,Risk Perception,and Sea-Level Rise: A Perspective

This article uses coastal flood insurance policy in the United States to discuss the influence of historical and existing policy frameworks on the development of new policy directions in coastal management within a context of risk perception. It is presumed that under conditions of current and future sea-level rise, coastal planning will have to develop forward-looking policy instruments focused on managing human expectations, particularly the expectations of those living along the coast. Planning will be supported, in large part, by evolving scientific evidence on sea-level rise and the attendant hazards that accompany this phenomenon. It is likely that policy proposals for future coastal management will deviate to some degree from previous management practices. The role of previous management practices in supporting a perception of risk that deviates from actual risks is explored using historical and current coastal flood insurance policy in the United States as an example. The goal of this analysis is to highlight the importance of community risk perception, as a function of past policy practice, when considering new coastal management policy directions.
