Age of Uncontrolled Information Flow

We are heading into an era of uncontrolled and uncontrollable information flow. In the past, the tools of information flow required large investments, and the persons controlling them were easily identifiable. Now, effective long-range communication with large numbers of people can be done using tools that are easily affordable to the average citizen. Moreover, it can be done in ways that make monitoring and control virtually impossible. This is not a worrisome future change that can be averted by prompt action; it is a fait accompli and there is no reversing it. However, this is not necessarily clear to those interested in monitoring and control. Unfortunately, the bulk of electronic communication is still relatively exposed to monitoring and control, and is likely to remain so for a while. The danger is that the authorities, trying to retain a grip on a situation that is irretrievably slipping away, will react to the extremes of the problem in ways that leave ordinary users' privacy unprotected. The best approach is to adapt traditional solutions rather than inventing new ones. The safeguards built into the traditional solutions may not be precisely appropriate, but they are far better than nothing.

New, technology-based firms in small open economies—An analysis based on the Finnish experience

This paper analyses the roles and impacts of new, technology-based firms (NTBFs) in a small open economy, with empirical data from Finland. It is suggested that in small open economies, NTBFs may fall into a resource trap, which might result in their being relatively less growth oriented than NTBFs in countries where the domestic market is larger. Consequently, in small open economies, the systemic impact of NTBFs could be emphasised rather than their organic growth in terms of the employment that they create.     

社会网络视角下的企业知识网络研究

知识经济时代,知识成为企业核心资源;知识的更新速度不断加快,而企业所拥有的知识存量有限,为保持竞争优势,知识网络已成为组织实现知识管理的有效实践工具和实践知识管理的主要平台。文章从社会网络视角入手,探讨了企业知识网络概念及内涵,分析了社会网络三大核心理论——强弱联结、社会资本、结构洞,论述了该理论对企业知识网络的影响,提出了构建企业知识网络交流平台的方法。

Predicting Employee Turnover from Friendship Networks

Employees (n=40) at a fast-food restaurant were surveyed about characteristics of their position and their level of satisfaction. Employees were then asked to report with whom they regularly communicated inside and outside the workplace and to indicate how close they were to employees with whom they were linked. Employee turnover was measured after three months had elapsed. A goal of the research was to replicate a model of employee turnover that predicts employees more central in their social network to be less likely to leave, and to test a social support explanation of the centrality model. The results indicated that employees who reported a greater number of out-degree links with friends were less likely to leave. The number of in-degree links with friends did not significantly predict turnover, and neither did network links with peers. Friendship prestige, measured by the number of in-degree links, was strongly correlated with relational closeness and amount of time spent with employees outside the workplace.

基于Google Earth的车辆防碰撞虚拟仿真系统

车载自组织网络（VANET）是近年来智能交通领域的研究热点之一。在VANET网络中,智能车辆通过交互共享道路环境信息,可提高交通安全水平。在现实环境中进行大规模的车载自组织网络实验,在经济性和可行性上都具有较大困难。在SUMO交通仿真基础上开发出车辆防碰撞虚拟仿真系统,通过Google Street Map获取真实道路环境（如路网、楼宇、植被等）,并结合 GEMV2软件对智能车辆在真实道路环境下的无线通讯链路质量进行评估,实现了虚拟行车交通流与车辆间无线通讯质量评估两位一体的模拟仿真,增强了车辆对周围道路交通环境的综合感知能力。
