After learning about the crisis of September 11, Americans overwhelmingly turned to television for more information. However, people used multiple sources of information. The Web and e-mail appear to have played important but secondary roles to television and the telephone. Overall, the media functioned well in meeting the extraordinary demands for information and communication. 相似文献

This article explores how ordinary people used telephone technology during the September 11, 2001 terrorist attacks on the USA. Personal emergency communication is heavily imbued with emotional meaning. These messages address major life problems and values, such as leaving final messages and expressing love and concern, sometimes requiring extreme efforts. They also show that formal technical characteristics of media, and boundaries across media, are not particularly salient to people who have pressing personal and social communication needs. 相似文献

Abstract Proposed changes to the Australian cross‐media regulation prohibiting common ownership of commercial free‐to‐air television and radio services and daily newspapers in the same market and their likely impact on diversity of opinion are evaluated in this paper. The analysis indicates that the replacement of the cross‐media rules with a minimum number of voices rule will lead to increased concentration of main media and reduced diversity. There is little evidence that the Internet and other new media are significantly displacing traditional media as independent sources of opinion in the domestic market. Also, the proposed number of voices rule is assessed as a largely ineffective and inefficient regulation. Consequently, the paper concludes that while abolition of the cross‐media rules might be an appropriate objective in the longer term, the proposed changes are likely to have undesirable effects on diversity of opinion in the immediate future. 相似文献

Abstract How are new media, such as electronic mail, voice mail, and fax, used when people have access to several of them simultaneously? This paper reports findings from a field study of media use in four sizable subunits within two large organizations where most employees had access to email, vmail, and fax. Respondents tended to use multiple electronic media rather than relying on one. However, they also showed a tendency to prefer one medium for asynchronous communication and to use the others for occasional, specialized purposes. Further, there were considerable differences across subunits in typical media use patterns. Although respondents expressed strong desires for multimedia integration, this study suggests that technological integration may not necessarily result in seamless, collaborative work. 相似文献

Abstract Rural communities face a multitude of hazardous conditions—from blizzards, floods, droughts, and insect infestations caused by nature to hazardous material spills, transportation accidents, and dam failures that result from human activities. Information technology offers to rural emergency managers potentially important tools with which to better plan, alert, and respond to disasters. Three case studies are presented about uses of different technologies. Each technology is currently in place, but not in widespread use. The first case is the use of a microcomputer in a rural Minnesota county to manage emergency resources, aid planning, and other important tasks. The second case uses cable television as a two‐way alerting link to fire, emergency medical, and police systems. The third case involves the use of satellites to form a statewide communication system among emergency service offices. Each use of information technology clearly contributes to improved emergency management, but widespread application is necessary before the full impact of information technology in rural emergency management can be felt. 相似文献

Abstract Individuals who have ready access to three new communication media— email, vmail, and fax—may elect to use only one medium, or two or more in combination. Users make choices based on evaluations of the utility of each medium for their communication tasks (a function of the types of work they perform). Individuals may assess technological characteristics to evaluate the technological utility of each medium. However, since communication media require multiple users, individuals also may be expected to assess characteristics of the user community to evaluate the social utility of each medium. Social utility may be influenced by people's perceptions of the existence of a critical mass of media users, and by the social influence of their peers and superiors. This study finds that perceptions of the technological and social utility of email, vmail, and fax are relatively independent of the types of work people perform. Social utility explains media usage somewhat better than technological utility, except in the case of email. Thus, the concept of social utility should be given more attention in future investigations of media choice. 相似文献

Abstract The development and deployment of technologies for delivering broadband services to homes in Australia are investigated using the ‘social shaping of technology’ (SST) approach. The focus is on the period from 1993 to 1998 when there were five main technological options for delivering residential broadband services: ‘hybrid’ fibre coaxial (HFC) cable; direct broadcast satellite (DBS); multipoint microwave distribution systems (MDS); ‘Integrated Services Digital Network’ (ISDN); and ‘Asymmetric Digital Subscriber Line’ (ADSL). The main broadband services planned for delivery to homes over this period were pay television and fast Internet access. A sequence of snapshots of sociotechnical relationships at critical times during the study period, termed ‘sociotechnological configurations’, is used to track the evolutionary pathway of the broadband technologies. The mapping technique assists in identifying key features and explaining the driving factors of the pathway, including why HFC cable emerged as the predominant technology, and two competing HFC cable networks were rolled out in capital cities at an additional cost of over $2 billion when a single network would have had ample capacity. 相似文献

AbstractIn this article, we report results of interviews conducted with 20 informants at 8 community radio stations across the major regions of Bolivia. We explore the activism and community practices that have energized Bolivian community radio stations over a sustained period. We are in particular interested in the bottom-up networking by these community stations to interlink with each other. These networks actualize the goals of horizontal and participatory communication called for by Latin American theorists. We seek to learn from these endeavors and also contribute to their continued flourishing by analyzing potential threats to them. 相似文献

The management of our households and the way we spend our leisure time has been greatly influenced by the introduction of various household technologies in the 1980s and 1990s. This paper compares the extent and rate of adoption of selected household products in Australian households. The diffusion of colour television sets, video cassette recorders, compact disc players, microwave ovens and personal computers into various types of households during the 1980s and 1990s was examined. This study found that different types of Australian households adopted new technology at different rates. The levels of ownership of various household technologies were highest for households with children. In general, one-adult households were slower to adopt new household technology when compared to other types of households. This paper speculates as to why one-person households are slower to purchase the latest in cooking and entertainment technology. 相似文献

Abstract Long‐distance education is now possible because of advancements and improvements in international telecommunications. This paper sets forth the concept of a “University of the World” in which students use computers, radio, and television to take courses in their chosen discipline and, in return, receive course credit and even academic degrees. The author describes the concept, its educational goals and objectives, the availability of courseware, the impact of global instructional technology, and questions of cost and technological capability. The organization, governance, funding, and operation of the University of the World are also described, including remarks on the benefits of membership and the functional value as seen from the student's perspective. 相似文献

This paper contrasts the immediate representations of Islam on US television and CNN's online messageboard by focusing on the noun phrases for 'Islamic' used in both media fora from September 11 to 16. The study found some notable congruities and differences in the associations made with Islam in each context. It considers these findings in terms of previous research on the representation of Islam and terrorism in 'Western' media; the official insistence that 'we' are not at war with Islam; and media theories of 'framing' and 'reception'. 相似文献

AbstractIn this Perspective paper we propose a rethink on how we should approach digital and analog news. Although there are literatures that continue to focus on the many and varied characteristics of digital and analog news, we should not consider these as separate, opposing entities. In fact, the intertwining between the digital and the analog of news makes it difficult, if not impossible, to define separately what they are, even if this often is the practice in scholarly debate on news and journalism in new media. What we argue in this paper is that today, in opposition to binary definitions, it would be much more revealing, and also connected to actual media practices, to try to understand how much digital there is in the analog news and, vice versa, how much analog there is in digital news. This approach recognizes three dimensions in media platforms: digital, analog, and, between them, a cross-evolved, digitalized analog present in television, radio, and online newspapers. Recognizing these three dimensions enables us to explore more clearly the implications that the hybridization of digital and analog news has on the overall media system and on the state of news itself. 相似文献

In April 1997, Tasmania (Australia) adopted the reputably successful New Brunswick (Canada) industrial strategy to build an information technology (IT) industry of significance. The strategy aims to overcome isolation in small regional economies and structurally change from declining natural resource industries. Both plans reject neo-classical economics-based industry policy, opting instead for a strong state-based investment planning approach. An analytical framework is set out, using Adolph Lowe's 'Instrumental Analysis', to examine implementation of both IT strategies. Implications of this analysis are drawn for any attempts at developing IT regional plans and, more generally, as a guide for broad strategic-based national industrial strategies. 相似文献
