中兴国际化：基于价值链理论的分析

中兴从1995年开始向国外拓展,到2007年,国际市场营业收入达到57.8%。在国际化发展中,由于受通讯设备制造业行业特点的影响,中兴重视价值链整合,在局部价值活动上偏重于企业价值链中的技术研发和市场开拓,注重通过与运营商合作来实现增值业务价值链,并通过低成本优势和差异化竞争实现国际化发展中的竞争优势。文章认为要保持国际化发展中的持续竞争优势,中兴应关注企业创新、效率和风险规避。     

The use of storm water to enhance a coastal swamp

The purpose of this study was to quantify the potential of available storm water to mitigate the adverse impacts of impounded saline water within a 1,336-ha, forested coastal ecosystem. A site-specific hydrodynamic model was constructed to predict the spatial influence of reduced salinity resulting from the continuous discharge of storm water, at a volume of 2.83 cubic meters per second (cms), directly and indirectly into the study area. These results were then incorporated into the Wetlands Value Assessment (WVA) model to quantify wetland benefits to specific habitats.The results show that the discharge of 2.83 cms of storm water can significantly enhance wetland functions within the 1,336-ha coastal ecosystem. The most benefit occurs when the storm water is discharged directly into the swamp via dedicated channel or pipeline, in contrast to discharging into an existing bayou within the subbasin and directing flow into the adjacent wetlands. Utilizing the WVA methodology, direct discharge is predicted to result in a net wetland benefit of 725.97 Average Annual Habitat Units (AAHUs). This benefit is largely attributed to reductions in salinity and an improved water regime (mixing) within the declining baldcypress swamp.     

《滇系·赋产》的史料特点及价值

清人师范所撰辑《滇系》，汇集前志之精华，内容丰富翔实，但又因多未注明出处，故使用时颇感不便。因此，系统考校该书史料来源及价值特点，就成为整理地方古籍文献一项重要任务。作者以该书中《赋产》篇所辑经济史料为例，作了全面系统的分析。

VaR模型在金融领域的应用分析

根据对金融资产价格分布特征的不同假设 ,常用的风险价值 (ValueatRisk ,VaR)模型大体可分为以下三类 :得尔塔 -正态法、历史法和蒙特卡罗模拟法 ,该模型由于在量化风险和动态监管方面的独特优势 ,目前已经在欧美许多金融机构的内部风险管理、监管信息披露、业绩评估等方面获得广泛应用 ,随着我国金融市场的市场化程度的提高和投资工具的日益增多 ,引进该方法对提高我国金融风险管理水平有重要的现实意义     

Measuring Perceptions of Synergistic Circulatory Disease Risk Due to Smoking and the Oral Contraceptive Pill

There is evidence that the oral contraceptive pill (OCP) and smoking contribute independently to risk of circulatory disease. There is mixed evidence that the combined risk may be greater than the sum of these factors operating in isolation. Little is known about how the general population views the risks from OCP use, singly and in combination with smoking. Previous attempts at assessing whether the public views risks as operating synergistically have generally found evidence for subadditive models, where the combined risk is less than the sum of factors operating in isolation. However, concerns have been expressed over the validity of the measures of risk perception used. Therefore, this study used three distinct methods of measurement to assess the extent to which 241 undergraduate students perceive the risks of smoking and the OCP separately and combined, for circulatory disease. For all three methods, respondents read each of four vignettes describing information about a woman's risk factors (with high and low levels of both OCP and smoking), and then estimated risk of circulatory disease using one of the three risk measures. The three measures produced similar ratings. Consistent with the epidemiological evidence, information about smoking had more impact on estimates of overall risk than did information about the OCP For all three measures, responses were consistent with an additive model of risk from smoking and the OCP. This convergence of results from different methods suggests that all three methods of measurement employed, which all had a large number of response options, may be valid.     

可转换债券转换权的定价研究

作为企业融资、企业财务筹划、国有股权退出等领域的重要的金融创新工具,可转换债券在我国有着巨大的发展潜力。根据可转换债券具有债券和潜在股票的双重特性,文章分别从侧重于其期权性和债权性的角度对可转换债券转换权的定价问题进行了研究。阐明了可转换债券转换权的期权特征,讨论了可转换债券转换权的Black—Scholes定价模型和债券价值定价模型,指出两种定价模型在理论上的互通性和内在的一致性,并以2002年4月万科发行的可转换公司债券为例,对转换权的理论定价和实际定价结果及其差异进行了比较和分析。     

Missing data methods in official statistics in the United Kingdom: Some recent developments

In recent years an increase in nonresponse rates in major government and social surveys has been observed. It is thought that decreasing response rates and changes in nonresponse bias may affect, potentially severely, the quality of survey data. This paper discusses the problem of unit and item nonresponse in government surveys from an applied perspective and highlights some newer developments in this field with a focus on official statistics in the United Kingdom (UK). The main focus of the paper is on post-survey adjustment methods, in particular adjustment for item nonresponse. The use of various imputation and weighting methods is discussed in an example. The application also illustrates the close relationship between missing data and measurement error. JEL classification C42, C81
