The National Clearinghouse on Aging

This paper discusses the creation of the National Clearinghouse on Aging within the federal government and the involvement of the Clearinghouse in the planning and initial implementation of a proposed Service Center for Aging Information (SCAN). This automated, bibliographic information system and its proposed products and services are described. The differing user groups and information needs involved with gerontological research and the provision of social services to the elderly are also discussed.     

私人领域的凸现与当今媒介文化的“私人化”

私人领域是与公共领域,尤其是与国家权力相对的活动空间。私人领域在不同时期的起伏变化,影响着同时代媒介文化的发展与特色。当今,媒介文化在私人领域彰显的情况下,呈现出私人化的特色。但媒介文化过度私人化则容易导致忽视公共性、侵犯他人隐私、流于媚俗等问题,这是值得警惕的。     

Compliance‐gaining strategies and communicator role: An analysis of strategy choices and persuasive efficacy

This study investigated not only those compliance‐gaining strategies senders are likely to use but also those strategies to which receivers are likely to respond. Results indicated that persuasive efficacy is maximized when explanation, direct request, and ingratiation are employed, while more punishing strategies such as threat and guilt are mutually perceived as ineffective. The interaction effect of size of request with communicator role proved to be minimal.     

模糊逻辑在下一代通信网络接入控制设计中的应用

研究了智能技术中的模糊逻辑在下一代OFDM通信网络接入控制中的应用,分析比较了几种典型的呼叫接入控制法在不同的数据及会话类业务及不同业务强度的情况下的阻塞率。仿真分析表明模糊逻辑接入控制法与基于门限法及基于队列信息接入控制法相比,具有更高的带宽利用率。     

基于OPNET的MVB总线仿真研究

列车网络控制技术是高速列车发展的一项关键技术。为了评估多功能车辆总线（Multiple Vehicle Bus,MVB）车辆级网络通信系统的性能,优化网络设计,采用Opnet Modeler搭建车辆级通信网络模型,包括车辆的网络拓扑结构模型、链路模型、节点模型和进程模型。利用所搭建的模型,对车辆级通信网络的时延性、吞吐量仿真。通过分析仿真过程中采集的数据,可以预测车辆级通信网路系统存在的问题,为改良、优化高速列车通信网络提供可靠的依据。     

Defending the Boundaries: Identifying and Countering Threats in a Usenet Newsgroup

This article is an account of a Usenet newsgroup whose participants, in response to a perceived 'invasion' of 'barbarians,' explored and articulated the value of the group, the nature of the crisis facing it, and the strategies available to meet the crisis. The newsgroup facilitated political and personal support for some gay, lesbian, or bisexual men and women. The primary threat to the group was the increasing number of newcomers who were oblivious to established norms, who tended to view access to the group as a commodity, and who attempted to impose 'outside' paradigms on the operations of the group. Defensive strategies involved calling on rhetorical devices (such as flaming or ostracism) or structural resources (such as employers, network operators, or lawsuits). All strategies had the potential to backfire, but rhetorical strategies were less risky, more available, and more community affirming than strategies requiring access to structural resources. Through this account, the article addresses the mutual linkages and dependencies between the social and technical organization of computer-mediated communication (CMC) networks, the community-building activities taking place through those networks, and the social, legal, and economic structures in which those networks are embedded.     

Independence and obedience in the United States and Japan

Are some Americans and Japanese beginning to think more similarly about independence and obedience? Middle-class adult respondents from the suburbs of Chicago and Tokyo (U.S.: 43 males and 54 females: Japan: 71 males and 80 females) were surveyed about their sex-role values. This report focuses on two values which have been recognised as constituting fundamental differences between Japanese and Americans: personal independence and obedience. The survey used a metric multidimensional scaling technique called Galileo^®. Analyses of the data and results of other comparative studies suggest that any convergence taking place between the two societies is occurring primarily within American society. There is growing evidence, including the findings of this study, that Americans are moving away from their traditional stress on the importance of the individual in society. The Japanese respondents did show a more liberal conceptualization of the ideal woman with respect to obedience, however, there was no indication that this less traditional image of women extended to their other traditional roles in society.
