What Can Be Learned from DuPont and the Freon Ban: A Case Study

Between 1974 and 1988, executives of DuPont, the world's largest producer of CFCs, were confronted with emerging evidence that CFCs were destroying the stratospheric ozone layer. The difficulty that executives face in such cases is that scientific knowledge develops over time and does not necessarily proceed in a straight line toward true conclusions. At the beginning of a new field of research, there is much uncertainty and disagreement among the experts. The solution of the ozone problem required a remarkable cooperation among science, business, and international governments. After looking at the role of DuPont executives in this drama, and the difficulties facing any executive dealing with uncertain science, the paper turns to an evaluation of the field of Business Ethics to see what light it might throw on this and analogous problems. Finally, the paper offers specific suggestions in terms of principles in dealing with uncertain science, and concludes that the course of action that DuPont followed, including some mistakes, can serve as a model for analogous crises.

Critical resource: An institutional economics of the Internet addressing-routing space

This paper links the analysis of IP address policy to the established vocabulary and concepts of institutional economics. Internet addressing and routing are usually discussed in technical terms, yet embedded in this highly technical discourse are a number of critical economic concepts, such as scarcity, externalities, common pool resources, tragedy of the commons, and conflict over the distribution of costs. To solve these problems, governance institutions native to the Internet have evolved. Yet despite the centrality of addressing and routing to Internet governance, there is very little research literature that bridges economic, institutional and technical discussions of IP addressing and routing. This paper connects the techno-economic discussion to analysis of institutions and governance arrangements.     

An acceptance model for an Internet protocol television service in Korea with prior experience as a moderator

This study examines the effect of users' prior experience on the adoption behaviour in the Internet protocol television (IP TV) service domains. This article proposes a new acceptance model for an IP TV service considering the moderating effect of experience and verifies the model with an empirical study. Respondents are classified into either experienced or inexperienced groups according to their prior experience with the IP TV service. The results indicate that motivational factors used in our study affect behavioural intention. In addition, this study shows that the influence of extrinsic motivational factors on the behavioural intention are stronger for the experienced group than the inexperienced group and the influence of intrinsic motivational factors on the behavioural intention are stronger for the inexperienced group than the experienced group. This article concludes with study implications, as well as limitations and future research directions.

战术Ad Hoc网络中的QoS路由协议设计与仿真

基于TDMA的战术Ad Hoc网络,提出一种分布式的资源预约机制,其中收/发节点采 用协商的方式预约时隙,邻居节点通过侦听方式获得时隙被预约的信息,然后依托该机制提 出一种QoS路由协议,该协议能够在网络节点之间选择一条满足QoS要求且相对短的路径进行 预约时隙,同时对于网络拓扑变化引起的链路故障也能局部修复。仿真表明该协议具有开销 小和可靠性高等特点,能够提高战术Ad Hoc网络的QoS保障能力。
