系统动力学仿真模型在决策支持中的作用——以中国可持续发展模型在CO2排放决策中的应用为例

系统动力学模型是一种重要的模型方法。文章主要介绍了中国科学技术信息研究所开发的中国可持续发展模型,并以水泥和钢铁行业CO2排放模型作为案例,分析了模型在CO2减排中的政策意义。在不同的情景设定下,中国水泥和钢铁行业的CO2排放会有很大的不同,每一种情景都对应着相应的政策选择。利用需求面和技术面的组合政策,有利于我国整体的CO2减排。

Florida public hurricane loss model: Research in multi-disciplinary system integration assisting government policy making

Homeowner insurance rate making is an important public policy issue in the State of Florida. The State of Florida has over 2 trillion dollars of residential properties exposed to hurricane risk. The State has declared that it shall adopt public policy to encourage the use of sophisticated actuarial methods to assure that consumers are charged lawful insurance rates (Section 627.0628(1)(a)). To that effect, the State's insurance regulatory agency, the Florida Office of Insurance Regulation (OIR), sponsored the development of a Florida Public Hurricane Loss Model (FPHLM) to assess the risk and project insured residential losses. The FPHLM is an open and public model that has been developed primarily by university experts without influence from either the insurance industry or the state regulators. It is open to public scrutiny and provides an understandable baseline to check the assumptions as well as the outputs of the proprietary models. The FPHLM thus makes the rate evaluation process more objective and less political. It enables the state to justify rejecting or accepting rate increases based on an independent and transparent model, rather than a process that can be influenced politically. As a multi-disciplinary large scale research project with an iterative and incremental development cycle, the FPHLM system development and integration faced numerous challenges varying from technical factors to project management aspects. This paper will discuss the research experiences accumulated during the development of the FPHLM and the impact it has had on the homeowner insurance rate filing process in the State of Florida.     

Enhancing the case for Electronic Government in developing nations: A people-centric study focused in Saudi Arabia

The pace of implementing Electronic Government (E-Gov) is rapidly increasing. However, despite high levels of investment, a broad range of applications, and various methods of access relatively low levels of various methods of access, relatively low levels of usage (and even familiarity with e-gov) are still common. For example, in Canada, long recognized as a leader in implementing e-gov, less than 27% of Canadians used E-Gov during the past 12 months and 81% of c non-users report a low level of familiarity with either federal or provincial governmental services available through e-gov (Canada, 2004). Or, consider the showcase e-gov Gyandoot project in the Dhar district in central India, whose population is estimated at 1.7 million. Even after implementing e-gov in a showcase project for the rural poor, a study by the Center for Electronic Governance, Indian Institute of Management, Ahmedabad concluded that this model of “government to citizen” service delivery has serious sustenance problems (World Bank, 2004). The research reported in this paper takes a step back and focuses on the acceptability of e-gov by individuals. It is a people-centric approach to determine the overall acceptability of e-gov to people in a developing country, Saudi Arabia. Although this research may be generalizable to other situations, the primary intention of this project is to shed light on how to approach and manage implementation projects in developing nations.     

基于概率图模型的科研文献主题演化研究

学术文献的主题分析对于研究者进行思路整理及发现研究主题非常重要.通过进一步的分析,能够理解主题如何发展变化,以及如何影响研究者的行为等等.探索了基于概率图模型的科研文献主题演化问题,特别分析了主题随时间的相互影响问题,提出了基于模块化网络的方法研究主题之间的相互关系,从而理解其相互影响.首先,利用主题模型获取时间文本的主题及其强度曲线,然后利用时间序列的逐段线性表示方法去除序列中的噪音,从而有效反映趋势信息,使得利用模块化网络能够更加准确地反映主题的影响关系,实验结果及其相关分析证明了方法的有效性.
