Investment decisions in the wireless industry applying real options

The wireless industry is one of the most capital intensive high-technology industries. This paper applies real options techniques to estimate investments under uncertainty in two new ventures: (a) deferral of the expansion from 2.5G to 3G networks; and (b) expansion of a 2.5G network using Wi-Fi as an alternative technology. The cases are examined and analyzed both qualitatively and quantitatively, using realistic assumptions and parameters. Investment cost, number of subscribers, pricing of services, and risk are at the core of investment decision processing. In both cases, sensitivity analysis of the value of the (real) option considering the above key parameters was conducted, to extrapolate useful findings that should be taken into consideration by the decision makers in wireless companies.     

当前高校创业教育管理模式与课程体系建设研究

高校创业教育是一种新的教育理念与模式，目前还处在不断发展阶段，还没有形成一个独立的学科体系和完备的教学模式。高校要设立专门的创业组织机构。创业教育对课程教学的开放性和灵活性、整体性和系统性、实践性要求更高。因此，要以创业所需基本知识为基础，以培养创业精神为核心，以锻炼创业能力为关键，不断完善“平台＋模块”的课程体系建设，突出“活动＋实训”实践课程环节，建立健全科学的创业教育课程评价体系。

The future of the mobile phone business

One of the fastest growing technologies of our times is that of mobile phones. In this article we use the assumption that the diffusion of mobile technology, as measured by the number of active mobile accounts, follows the well known S-curve of natural growth in competition systems. The accuracy of the logistic fit is tested against actual data for the whole world, Europe, China and the GSM system. Using the produced models predictions concerning the future of mobile business are deliberated.According to these models active mobile accounts around the globe are expected to grow from 1.7 billion in 2004 to approximately 2 billion in 2008, reaching a peak penetration of 29.2%. Growth barriers, apart from the age of the potential user, are also low income and extreme poverty. Europe, early adopter of mobile technology and leader in active mobile accounts against all other regions in the world, has apparently reached a peak with almost every European, apart from the very young or very old, using a mobile phone. The mobile market in China is anticipated to exceed 500 million active accounts and may increase even further depending on the economic and social reform that is currently under way in that part of the world. GSM will most likely remain the leading mobile technology in the future as it is today.The growth process for the world, Europe, and the GSM system is almost completed and during this stage instabilities may occur before the potential emergence of a new wave of growth.

电子政务成效评价模型及实证研究——以湖南省部分地级市为例

本文旨在研究电子政务是否及怎样作用于信息时代建立高效、公开、正义、廉洁服务型政府的机制。以公众和公务员为研究视角,综合电子政务的内部与外部绩效,构建以顾客满意度、电子政务应用实效、可持续保障机制、基础设施完备度等为指标体系的电子政务成效层次结构模型,并以长沙、株洲和郴州市政府的调查数据进行实证研究,揭示电子政务的成效。结果表明:电子政务成效总体属于中等水平,电子政务的功能性应用处于建设性阶段,对政务信息共享和电子化有较好的促进作用,但电子政务提高政务的执行效率有限。提出了各级政府应加大电子政务的功能性应用建设力度,协同创新政务管理策略,以此提高政务执行效率,实现服务型政府。
