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.     

Electronic journals and their unbundled functions in scholarly communication: Views and utilization by scientific,technological and medical researchers in Japan

In recent years, electronic journals are in common use in scholarly communication and we can interpret this situation in various ways. On the one hand, we can say that scholarly communication is now much dependent on electronic resources. On the other hand, it would be too simplistic to say that scholarly communication is now greatly dependent on electronic resources because researchers seldom use other electronic resources. The purpose of this article is to show the position of electronic journals in scholarly communication based on Japanese researchers’ information behavior and estimation. The main focus is on distinguishing the function of scholarly journal and the electronic form. A questionnaire was sent to 1427 physicists, 1026 chemists and 1276 pathologists in universities and other research institutes all over Japan, of whom 775 (54.3%), 494 (48.1%) and 541 (42.4%), respectively, supplied answers. The main results are as follows. Japanese researchers in STM fields use electronic journals as a matter of course, and other electronic resources to some extent, for accessing information; but this shift to electronic resources seemed to be not a transformation but a modification of traditional patterns of use. Researchers still rely on traditional scholarly journals for accessing information and publication, although their recognition has begun to change.     

Managing complex engineering projects: What can we learn from the evolving digital footprint?

The challenges of managing large complex engineering projects, such as those involving the design of infrastructure, aerospace and industrial systems; are widely acknowledged. While there exists a mature set of project management tools and methods, many of today's projects overrun in terms of both time and cost. Existing literature attributes these overruns to factors such as: unforeseen dependencies, a lack of understanding, late changes, poor communication, limited resource availability (inc. personnel), incomplete data and aspects of culture and planning. Fundamental to overcoming these factors belies the challenge of how management information relating to them can be provided, and done so in a cost eff ;ective manner. Motivated by this challenge, recent research has demonstrated how management information can be automatically generated from the evolving digital footprint of an engineering project, which encompasses a broad range of data types and sources. In contrast to existing work that reports the generation, verification and application of methods for generating management information, this paper reviews all the reported methods to appraise the scope of management information that can be automatically generated from the digital footprint. In so doing, the paper presents a reference model for the generation of managerial information from the digital footprint, an appraisal of 27 methods, and a critical reflection of the scope and generalisability of data-driven project management methods. Key findings from the appraisal include the role of email in providing insights into potential issues, the role of computer models in automatically eliciting process and product dependencies, and the role of project documentation in assessing project norms. The critical reflection also raises issues such as privacy, highlights the enabling technologies, and presents opportunities for new Business Intelligence tools that are based on real-time monitoring and analysis of digital footprints.

模糊信息流动过程的分析与刻画

思考模糊信息的流动过程离不开信息流逻辑,该逻辑的推理方向是从已知信息推知未知信息。我们会注意到人们在日常交际中所使用的语言本身就具有模糊性,而这种模糊性并不影响信息的传递,于是就产生了模糊信息何以在个体间准确流动的问题。本文运用信息流逻辑的方法,对模糊信息流动过程进行分析,进而刻画模糊信息的流动过程。

基于IEEE 802.11的Ad Hoc网络中的一种节能路由改进算法*

根据IEEE 802.11协议在链路层提供有限次数链路重传的特点,提出了一种在基于IEEE 802.11的移动Ad Hoc网络（MANET）中保证可靠通信的节能路由改进算法——ERRC（Energy-efficient Routing algorithm for Reliable Communication in IEEE 802.11-based MANET）,它可以方便地应用于MANET中现有的反应式路由协议。ERRC分析并建立了适合于IEEE 802.11情况的重传模型和能耗模型,提供了在发送数据分组时的功率控制机制,在节点选路时综合考虑了分组错误概率、节点代价函数的影响。仿真结果表明,ERRC算法可以显著提高网络生存期,在节省能耗方面比没有考虑分组错误概率的节能路由算法更为精确。

Testing the level of interactivity of institutional websites: From museums 1.0 to museums 2.0

The Internet has changed the way in which organizations communicate with their publics, and museums are not an exception. The consolidation of Web 2.0 has not only given museums access to a powerful new tool for disseminating information, but has involved significant changes in the relationship between institutions and their publics, facilitating and enhancing the interaction between them. The overall objective of this paper is to analyze the degree of interactivity implemented in the websites of major international art museums, in order to assess if museums are evolving towards more dialogic systems with relation to their publics. The results indicate that museums still have a low level of interactivity on their websites, both in the tools used to present information and the resources available for interaction with virtual visitors. But it has also observed that museums are progressively implementing interactive and dialogic sources, suggesting a clear trend towards new ways of managing these platforms in order to establish more participatory and collaborative communication systems with virtual users.

Universal Service: Separating the Grain of Truth from the Proverbial Chaff

The prevailing notions of information egalitarianism impel us to seek uniform solutions for all those who lack adequate access to information and communication resources. However, a careful separation of the symbolism of universal service from the real issues reveals that uniform solutions make sense for some resources and not others. This article proposes that uniform solutions should be formulated for resources used in the communication mode, but a segmented approach should be adopted for those used in the information access mode.     

重构与再造:预印本平台对科学交流体系的影响

预印本平台从诞生伊始便被学界赋予了对抗学术垄断，实现学术自由的重要使命，其在发展的流变中逐步确立了“去中心化”的科学交流体系。本研究通过案例分析，结合传播学、管理学的相关理论，探析了预印本平台对科学交流体系的影响。研究认为，预印本平台弥合了科学交流的时滞鸿沟，打造了符合学术共同体共享愿景的信息空间，但其过度开放可能引发科学交流的信任裂痕，产生新的数字鸿沟。未来，预印本平台需调和即时性与信息质控，资本化与科学公共性，资源整合与期刊利益之间的矛盾，推动科学交流的繁荣。
