Speeding on the information superhighway

Conclusion Because of the recent trend toward commercialization of the Internet, and the immense proliferation of information online, searching has become one of the most time-consuming tasks of our workdays. Technology is meant to help us save time and make more time for the things in our lives that are important to us. We can control our work with technology or allow it to control us. Because creators of some Web sites are trying harder and harder to get you to buy things online and to build up ecommerce, they are set up with the intent of distracting you into areas that are not likely to help you find the information you really need. Avoid the “impulse buying” and time-usurping aspects of the Web by controlling your own interactions with it. Plan, set goals, remind yourself of your task, and enjoy happy andefficient searching.

Managing Email Overload in the Workplace

The problem of email overload in the workplace, the feeling of being overwhelmed by the constant flow of messages appearing in the inbox and the inability to manage the high volume of messages effectively, is a current area of research in the field of human–computer interaction. Most current literature reflects three types of recommendations related to how to cope with or mitigate email overload in the workplace: email management techniques for the employee, strategies for the organization or employer, and inbox usability improvements. The state of current research related to email overload is reviewed and avenues for future research are suggested.

Surviving the Broadcast Media in Small Language Communities

Abstract

The broadcast media challenge the survival of small languages as never before. To date the result largely has been negative, since broadcast media can penetrate to the remote areas that often shelter small languages and can invade even the strongest small‐language sanctuary ‐‐ the home. Where modern media have been enlisted to serve small languages, the uses to which the small languages have been put have been mostly serious and usually educational. This emphasis on the serious overlooks the strongest attributes of most small languages: their rich individuality as repositories of local flavour and folk tradition. These could be mustered for use in broadcasting to great effect and benefit in the support of beleaguered small languages.

电子邮件是校园网服务中最主要的应用之一,其稳定性和灵活性对于校园网服务质量有着重要的影响.本文针对提高电子邮件系统的稳定性,增加邮件系统的灵活性,提出了基于负载均衡的多邮件网关/多邮件传输代理(Multi-MailGateway&Multi-MTA)的系统架构,使邮件系统具有较好的可扩展性,能支持大规模的并发访问,保证邮件系统7×24小时的连续稳定运行.该系统已在北京大学校园网上实际运行,取得了较好效果.     

道路施工对通行能力的影响分析

随着城市化进程的加快,城市交通基础设施建设需要不断完善。建设项目施工期间要在道路上设置作业区,遂使该段道路成为城市道路的瓶颈路段,容易诱发交通事故和交通拥堵。通过研究占道施工对路段交通带来的影响,可以评价施工区交通运行特性以及服务水平,针对施工区存在的问题及道路条件、交通环境的变化提出改进措施,以便进行相应的交通疏导。文章结合实际的交通现状,给出了道路施工对道路交通能力的影响模型,并提出了改善道路通行能力的具体措施。
