摘要：This paper will apply a politically oriented description-critique paradigm developed from the works of Whitehall and Grewell that offers a way to examine works of popular culture, particularly Mars-based science fiction films. Because of the unique nature of these films, primarily which they are set in a future and distant world, they allow us to explore the socio-political landscape in which they were created from a remove that does not exist in ＂real-world＂ based works. Specifically we will be examining the governing power （in any particular Mars-based science fiction film） that might be either wielded by business interests or governmental interests. Although it is possible to have both a strong government and a strong business in a society, in many Mars-based science fiction films, government and business seem to represent two sides of a continuum. The stronger the business power structure in the film, the weaker the governmental power structure, and vice-versa.

摘要：In many circumstances, chemical process design can be formulated as a multi-objective optimization （MOO） problem. Examples include bi-objective optimization problems, where the economic objective is maximized and environmental impact is minimized simultaneously. Moreover, the random behavior in the process,property, market fluctuation, errors in model prediction and so on would affect the performance of a process. Therefore, it is essential to develop a MOO methodology under uncertainty. In this article, the authors propose a generic and systematic optimization methodology for chemical process design under uncertainty. It aims at identifying the optimal design from a number of candidates. The utility of this methodology is demonstrated by a case study based on the design of a condensate treatment unit in an ammonia plant.

摘要：Due to the increasingly stringent standards, it is important to assess whether the proposed emission reduction will result in ambient concentrations that meet the standards. The Software for Model Attainment Test-Community Edition （SMAT-CE） is developed for demonstrating attainment of air quality standards of O3 and PM2.5. SMAT-CE improves computational efficiency and provides a number of advanced visualization and analytical functionalities on an integrated GIS platform. SMAT-CE incorporates historical measurements of air quality parameters and simulated air pollutant concentrations under a number of emission inventory scenarios to project the level of compliance to air quality standards in a targeted future year. An application case study of the software based on the U.S. National Ambient Air Quality Standards （NAAQS） shows that SMAT-CE is capable of demonstrating the air quality attainment of annual PM2.5 and 8-hour O3 for a proposed emission control policy.

摘要：为了评估空气污染带来的健康冲击、评估健康效益,克服现有评估工具(BenMAP V4.0)计算速度缓慢及用户体验较差等问题,受美国环保署委托,设计并研发了新一代空气污染与健康效益评估工具BenMAP CE,搭建了BenMAP CE的框架,进行了详细功能设计,并利用美国环保署提供的数据进行了实测.测试结果表明,基于相同的输入文件和设置,BenMAP CE能重现BenMAP V4.0的计算结果,相比现有的评估工具,BenMAP CE具有良好的用户体验、强大的GIS展示功能及大幅提高的计算速度.BenMAP CE是考虑了污染物环境浓度削减、人口密度、收入差异等经济因素的综合性评估工具,能为决策者评估空气污染控制措施所带来的健康效益提供辅助决策依据.
