跨文化交际语境中的文化自觉

文化自觉作为人类对待多样性文明的理性态度,是跨文化交际所追求的重要价值目标。文化自觉是跨文化交际的新境界,体现了文化的平等意识、反思意识、互补意识和发展意识。文化自觉能力是在跨文化交际实践中形成的。     

Does a Reactor Need a Safety Backfit? Case Study on Communicating Decision and Risk Analysis Information to Managers

An approach to communicating decision and risk analysis findings to managers is illustrated in a real case context. This article consists essentially of a report prepared for senior managers of the Nuclear Regulatory Commission to help them make a reactor safety decision. It illustrates the communication of decision analysis findings relating to technical risks, costs, and benefits in support of a major risk management decision: whether or not to require a safety backfit. Its focus is on the needs of decision makers, and it introduces some novel communication devices.     

从跨文化交际看俄语成语翻译

语言是跨文化交际中最主要的手段。在运用语言进行交际时 ,会遇到具有鲜明民族特色的成语及其运用、翻译问题。翻译过程中文化因素对于跨文化交际研究有着特殊的意义。本文就以上问题进行分析并提出几点看法。     

宽带光纤通信网

综述了宽带光纤通信网的发展动态。首先说明光纤通信网络与交换是光纤通信研究的重要领域之一。接着对同步光纤通信网、宽带综合业务数字网(BISDN)与异步转移模式(ATM)、宽带光纤局城网与城城网、Gbit/s级试验网等进行综述。最后简述一种新型光纤通信局域网。     

The Risks of Using Nuclear Energy Sources in Space: Some Lay Activists'Perceptions

A combination of directive and nondirective techniques was used to study the mental models of 30 lay activists regarding the risks of nuclear energy sources in space. Respondents'perceptions were compared with an "expert model" of the processes generating and controlling these risks, in terms of both the substance of their beliefs and several statistical measures of their performance. These analyses revealed a complex pattern of strengths and weaknesses. Their details are used to derive recommendations for formulating messages about these risks.     

Customer Perceptions of Agency Risk Communication

A government agency commissioned a baseline study of how its customers view the agency's risk information. The 70% response rate to a mail survey allows analysis by subgroups representing customers'primary interests. Although this agency traditionally has been responsible for ensuring plant and animal health at the farm gate (or where imported), responses emphasized emerging customer concerns about the environment and human health. Customers think many risk communication activities are important, but that the agency is not especially effective in conducting those activities. Customers are moderately satisfied with much of the risk information they receive, although many have little contact from or interaction with the agency. Customers identified other sources they use, which suggest potentially effective channels for this agency's risk messages. The study provides a baseline for measuring change in the agency's risk communication effectiveness. It also can be a model when other organizations plan their own risk communication evaluations.     

卫星气象资料广播分发差错控制技术的研究

研究了适用于卫星气象资料广播分发的三种差错控制技术方案,并用计算机进行了大量的性能模拟试验,证实了采用BCH(127,106)的方案可将误码率从10~(-3)改进为<10~(-9),传输效率为81％;卷积码的维特比(Viterbi)译码(r=1/2,k=6)方案对误码率可提供更大的改善,但传输效率<50％;收缩码方案(r=2/3,k=6)在随机差错模式下的性能甚至比预料的更好。     

利用WSEIAC模型进行通信系统效能评估

全面阐述了常用于系统效能评估的ＷＳＥＩＡＣ模型，给出了从不同角度定义效能，以及各单元的ＭＴＢＦ、ＭＴＴＲ在不同数值组合时，利用该模型对通信系统效能值的计算结果。这一评估模型充分反映了单元的可靠性、维修性水平对系统效能值的影响。

本文从中国文化乃至世界文化的大背景下,对中国文学史上作家并称的现象作了宏观的审视,试图揭示其产生的根源并论述其作用与特点,为文学史的研究提供一个新的视角。     

ATM无线网纠错编码研究

根据６０ＧＨｚ无线信过的特点提出对ｃｅｌｌ字头和信息字段分别采用ＢＣＨ短码和ＲＳ编码方法。另外，还提出了一种新的ｃｅｌｌ字头，包含新提出的ＢｌｏｃｋＮｕｍｂｅｒ字段，能对付深衰落造成的长突发错误，且与原ｃｅｌｌ字头兼容，理论计算表明，所提出的纠错编码方案能比较有效地将６０ＧＨｚ无线信道质量提高至ＡＴＭ技术适应的水平。指出了在６０ＧＨｚ无线信道条件下，采用ＡＴＭ技术实现无线通信网综合业务是可行的。
