Assessing Cross-Media Impacts: A Comparative Risk Approach

The Oregon Department of Environmental Quality has developed a Cross-Media Comparative Risk Assessment model to address certain regulatory concerns. The model generates a Human and Ecological Risk Index for a facility releasing toxins into the environment. The risk indices are based on chemical fate and transport predictions, toxicity, population density, and ecological sensitive areas. The model can be used to rank facilities for inspection or as a tool to assess the progress of pollution prevention programs. Regulatory permitting departments can use the model to address the cross-media transfer of pollutants from one environmental compartment to another. The versatility of the model allows adaptation to each specific users needs.     

Non‐dominated Time‐Window Policies in City Distribution

Urban freight contributes significantly to pollution, noise disturbance, traffic congestion, and safety problems in city centers. In many cities, local governments have introduced policy measures, in particular time‐access restrictions, to alleviate these problems. However, setting time windows is very challenging due to the conflicting interests and objectives of the stakeholders involved. In this article, we examine whether it is possible to develop time‐window policies that enhance environmental sustainability and distribution efficiencies, while meeting the objectives of the municipalities. We develop a framework for balancing retailer (costs), municipality (satisfaction), and environmental (emissions) objectives, using data envelopment analysis, under different urban time‐window policies. The approach is illustrated by a case study of three Dutch retail organizations, with a large number of stores affected by such time windows. On the basis of an evaluation of 99 different time‐window policies, our results show that harmonizing time windows between neighboring cities leads to the best overall performance. The currently used time‐window policy appears to perform reasonably well, but can be improved on all dimensions . However, harmonizing time‐window policies may be difficult to realize in practice.     

从接受美学角度解读旅游翻译——以五台山菩萨顶导游词的汉英翻译为例

旅游业在全球范围的迅猛发展对世界经济文化产生了巨大的影响,搞好旅游翻译研究不仅具有文化交流意义还具有紧迫的现实意义。在与世界密切接轨的今天,旅游业是山西经济文化建设的给力杠杆,因此,提升旅游文本翻译质量势在必行。接受美学是现在最活跃的文学批评流派之一,把读者视为文学研究的对象,看重作品和读者的关系。本文拟从接受美学的角度解读旅游翻译,通过对五台山菩萨顶导游词文本的研究,剖析当前导游词文本英译中存在的问题,并提出相应的合理化建议,以期对山西经济发展起到积极推动作用。     

中国粮食流通与粮食安全：关键节点的风险识别

粮食安全不仅取决于粮食生产的量和自给率,还取决于可获性,包括“买得起”和“买得到”。当前中国粮食总量安全,但粮食生产的区域结构性矛盾突出,粮食生产日渐向优势区域集中,主销区的粮食消费日益依赖于主产区的粮食调运,粮食运达的及时性对于粮食安全愈发重要。粮食调运必然面临长距离运输问题,这其中尤以在粮食运输网络中起枢纽作用的关键节点的平稳有序运行最为关键。当前实现粮食调运的运输方式主要依靠铁路、水路以及铁水联运,但是这一运输网络存在运力不足、物流方式落后、基础设施建设不足等风险因素,与粮食运输量的增长速度以及运输的顺畅性、及时性要求不相匹配,因此亟待通过加快铁路、水路基础设施建设、推动粮食物流方式变革和健全粮食物流应急响应机制等措施,保障粮食的稳定供给和粮食安全。     

人类学仪式理论视角下文化产业“神圣游程”体验模式

文化产业是对现代性的"好恶交织"。消费者在日常生活与文化产业之间进行"逃离—回归"的往返循环,相应地产生"世俗—神圣—世俗"的转换体验。该过程可表示为文化产业的"神圣游程"体验模式,由分离、阈限、聚合三个阶段构成。该模式与旅游"神圣游程"体验模式在异质性体验和人际互动方面存在明显区别,但本质上同为"体验差异"的现代性生存哲学的体现。     

两岸航空区际法律适用制度比较论纲

航空直航是两岸经济文化交流的重要路径。两岸航空法律冲突的存在导致航空直航中当事人利益保护的不确定性。当事人在发生纠纷时无法确定准据法, 难以确定其权利义务分配的法律效力。两岸航空法律适用制度的冲突加剧了实体法冲突的消极影响。两岸航空直航运输合同法律适用制度、航空器权利法律适用制度、旅客权利能力与行为能力法律适用制度及侵权法律适用制度均存在一定程度的差异, 其准据法的连接点、法律选择方法与价值考量迥异。两岸航空私法冲突属于区际法律冲突, 与国际私法冲突存在一定差别。应当制定区际私法, 以解决两岸航空法律冲突问题。     

Confidentiality,power relations and evaluation of potential harm in the study of the personal and organizational networks of travel agents in Moscow

Network research in organizational contexts faces ethical challenges related to revealing the identity of participants, managing power relations, and managing the interests and potential harms of the different stakeholders. In this article, we review the ethical issues associated with the investigation of the personal and organizational networks of travel agents in Moscow. In our case study, we interviewed 32 tourism agents from Moscow and its region, obtaining information on 45 people with whom they have regular relation as part of their work; and relational data, with a 2-mode matrix, on 15 organizations with which the agency could be linked in the Russian-Andalusian tourism market. Our results highlight the utility of presenting the information of personal networks in an aggregate manner. It also demonstrates the value of cultural adaptation strategies and adjustment to the characteristics of the community. Moreover, the central role of power relations in organizations, within a cultural context with a greater distance to authority was also found.     

新常态下交通对中国经济质量增长的贡献

根据交通外部性和非线性理论构建交通门槛模型,并基于1985-2012年中国省际面板数据,采用Hansen门槛效应的内生分组方法检验新常态下交通对中国经济增长质量的贡献。结果显示：新常态下交通对经济增长质量贡献略低于"旧常态",但仍表现出区间"递增"趋势;把新常态下TFP分解为技术进步和技术效率,发现中密度地区要素配置结构已不适应技术进步的需要,高密度地区技术效率相对技术进步对经济增长质量的贡献较低;随着区间交通密度的增加,"政府干预经济"更有效率,但城市化和产业发展对经济增长质量贡献由正转负。为进一步提升新常态下交通对中国经济增长质量的贡献,应定向适度加大"中密度地区"交通投资力度,助其跳出"低增长陷阱";借助信息化、智能化手段引领交通建设转型升级以提高经济运行效率;构建"交通-产业-城镇"三位一体的协同新型综合交通体系;协调好城市化与交通基础设施建设之间的关系。     

考虑学习效应的可复用物流容器供应链的最优运作决策研究

本文研究了单个制造商通过可复用物流容器将产品送至单个零售商的闭环供应链,在可复用物流容器回收处理后得到的数量小于发出时数量的条件下,本文考虑可以通过工人操作过程中存在的学习效应来降低可复用物流容器的丢弃率。本文构建了两个模型：模型1未考虑维修中心工人操作过程中存在的学习效应,可复用容器的丢弃率为随机变量;模型2考虑维修中心工人在操作过程中存在学习效应,使得可复用物流容器的丢弃率不断降低。通过定量分析确定了最小联合库存总成本下的最优运行周期、货物配送次数以及可复用容器配送次数。结果表明,在任一供应链参与者不采取降本措施的情况下,仅考虑工人在操作过程中存在的学习效应就可以起到降低容器丢弃率、节约总成本的效果。此外,本文还分析了制造商可以支付给工人的最大维修费用,为企业的成本投入预算提供决策依据。
