依据Web 页面和W eb 站点可以被搜集和分类, 文章探讨的主题是:WWW 构成图书馆。结论是:Web 不是数字化图书馆, 但是图书馆可以从Web 中选择搜集材料。Web 文献有两种变化形式。第一种变化形式是本文所谈论的“持续性”; 第二种变化形式是W eb 页面或Web 站点信息的变化。本文力求更进一步认识Web 页面和Web 站点的生存期, 生存期的变化会影响具有Web 信息的图书馆的完整性和有效性, 然而如果能够认识这些变化就可以进行控制和管理。 相似文献

Obtaining consumer data has become an essential practice of Web proprietors. This is because, compared with ‘brick and mortar’ retail stores, it is much more difficult for Web proprietors to build one-on-one or face-to-face relationships with customers. The collection of personal information online boosts customized services for consumers, but at the same time it increases concerns about privacy infringement. Using a content analysis of the most visited Web sites in Korea and the United States, this study compares the amount and breadth of information requested by Web proprietors and examines the relationship between the information requests and privacy policies of Web sites. This study found that Korea-based Web sites present stronger privacy policies than do US-based Web sites. Ironically, they also request a greater amount and variety of information from consumers than do US-based Web sites during registration processes. When narrowing the focus to US sites only, this study also revealed that the stronger the privacy policies presented by US Web sites, the more information the US Web sites request from consumers. 相似文献

The federal government's war on terrorism has heightened understanding and appreciation of the many facets of electronic government. Electronic government is used as a resource in the war on terrorism, helping to prevent and prepare for attacks. It might also prove useful in recovering from attacks. Unfortunately, e-government itself is a likely target for terrorists. Cyber intrusions into government Web sites and damage to, or destruction of, infrastructure, whether a computer system or an electrical grid that supplies power, could impair e-government. E-government is also attractive as a potential target for the information it provides, information that enemies of the United States could use in identifying weaknesses and planning attacks. While the Bush Administration has developed a comprehensive policy, based on a market model, for facilitating the use and effectiveness of e-government, its approach to e-government security, particularly in the area of Web content, has been ad hoc. Soon after the September 11, 2001, attacks, federal agencies began scrubbing their Web sites, an effort that has implications for the notion, and practice, of having a well-informed citizenry. 相似文献

Based on a survey of 419 industry professionals responsible for maintaining radio station Web sites and a content analysis of 900 radio station Web sites, this study provides an overview of the state of Web radio in the late 1990s. This study investigates the extent of Web radio, the range of content offered on radio station Web sites, the benefits realized as a result of having a Web site, and the problems encountered with Web sites, and makes recommendations based on the findings. A general conclusion of this study is that although the Web presents a wealth of exciting possibilities, most radio broadcasters are currently underutilizing the Web and their Web sites. 相似文献

SUMMARY There is a proliferation of Internet sites covering environmental themes. Many of these sites provide reference information in varying degrees. This article highlights environmental Web sites that provide a wide range of pertinent reference sources to a diverse audience. More than 50 highly selective Web sites are included in this paper. Some of these Web sites provide access to library catalogs, full-text articles, and other online resources. The Web sites in this article are in five categories: portals, government sites, special issues, general sites, and databases. 相似文献

This study compares the radio industry's use of interactivity to that of other traditional media on the Web such as newspapers and television stations, along the dimensions of audience-oriented interactivity and source-oriented interactivity. A content analysis of 112 traditional radio station Web sites, 282 traditional newspaper Web sites, and 128 traditional television station Web sites found that traditional radio station Web sites provided more audience-oriented interactivity compared to other traditional media Web sites, and traditional newspaper Web sites offered the most source-oriented interactivity. A general conclusion of this study is that although traditional radio stations were more likely to transmit live and archived sound than other media, all traditional media Web sites have held back from developing interactivity beyond e-mail, and have limited the transmission of streaming media, as well as archived audio and video content. 相似文献

Standpoint: Disappearing authors: A postmodern perspective on the practice of writing for the screen
The current study examined content-specific relationships of citizens' use of city Web sites with civic engagement. A Web-based, volunteer survey of 1,966 citizen users of city Web sites found that surveillance, practical services, and direct democracy features functioned as important conditions for citizens' real-world civic engagement. Results indicated that citizens' use of practical services and direct democracy features of city Web sites were associated with citizens' civic involvement and political behaviors. The findings suggest that the relationships between citizens' use of city Web sites and civic engagement differ according to the purpose for which citizens use the sites. The results of the current study exhibit an indication that city Web sites can promote civic engagement among citizens. 相似文献
