Interpersonal and media storytelling were crucial to information dissemination about the September 11 tragedies. The storytelling processes through which urban residents are transformed into members of a broader community are illustrated by their connections to media and their participation in neighborhood discussions and community organizations after September 11. This study demonstrates how a communication infrastructure approach contributes to understanding participation in civil society after September 11. 相似文献

This paper looks at the demand for Internet news sites before and after September 11. Analyzing information obtained from actual click-stream activity, support is found for the view that the events of September 11 changed the way households used the Internet to obtain information and news. These changes are observed long after September 11. 相似文献

Television's coverage of the tragic events of September 11 can be viewed and understood as a paradigmatic disaster marathon. The salience of the attack's visual images, their exclusivity on the screen for a protracted period, and the invisibility of their perpetrators enhanced the attack's effectiveness. The paper highlights a number of problems that the September 11 disaster marathon poses to the profession of journalism and to society, and points out possible remedies for the future. It ends with a short discussion of the ways in which television's coverage of the event both resembled and differed from the media-event model, and of theoretical aspects of its unique dimensions as a disaster marathon. 相似文献

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

We report findings here from an audience survey in New Mexico of the diffusion of a spectacular news event, the terrorist attacks on New York and Washington on September 11, 2001. This news event was perceived as very salient, and it diffused rapidly. The first terrorist attack occurred at 6:45 am (New Mexico time); within three hours almost all respondents had heard about the news event. Individuals reacted to this news in an emotional way, with many respondents praying, participating in a memorial event for the victims, contributing money and donating blood. The terrorist attacks also evoked a strong sense of patriotism. Compared to the news events studied in 52 previous investigations, the September 11 terrorist attacks caused stronger, and more emotional, audience reactions. 相似文献

This paper examines how Estonians dealt with the news concerning the September 11 attacks in the new electronic communication space of the Internet. This work will summarize people's discussions on the Internet relating to the September 11 attacks by outlining the different narratives that carried people's attitudes and knowledge. The paper aims to show that the Internet was used, not only as a medium for obtaining more information about the attacks, but also as a medium for discussion and crisis support. This research is based on: (1) a survey amongst Tartu University students and follow-up semi-structured interviews; (2) an analysis of the comment pages on Estonian electronic newspapers; and (3) an analysis of three chat logs from Estonian talkers. 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

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

Abstract “At present, the majority of [radio] programs heard are from sources outside of Canada. It has been emphasized to us that the continued reception of these has a tendency to mold the minds of the young people in the home to ideals and opinions that are not Canadian. In a country of the vast geographical dimensions of Canada, braodcasting will undoubtedly become a great force in fostering national spirit and in interpreting national citizenship.”1 This statement, written fifty years ago, could just as well have been written today. But, while the basic issue has remained unchanged over time, the uses to which information and communications can be put have steadily grown. The scope of the issue has also therefore increased. Included under the heading of communications and information today are such diverse but interconnected matters as broadcasting both by TV and radio, the newspaper, magazine, and book publishing industries, the film industry, advertising, computers and all computer communications, telephone and telecommunications, communications satellites, remote sensing, and, to a point, industrial know‐how and research and development. In this paper, I shall examine how communications and information affect such issues as Canadian unity, Canadian cultural identity, and Canadian economic viability. I shall concentrate on how Canadian governments have seen this issue, and, to a lesser degree, will show where the views of individuals and other interest groups may differ from government policy. 相似文献

This article describes the use of wireless telecommunication media within the different locations directly affected by the hijackings on September 11. Comparisons across these different contexts provides an empirical anchor to more general themes concerning the social dynamics of wireless in the unfolding events of this day. An indication is given of how the important social role of wireless phones in this crisis could redefine public views on wireless media and thereby shape policy and regulation in the years ahead. 相似文献

Abstract This paper reviews developments in the work force as they bear on training needs from entry level skills through professional continuing education. It summarizes the state of the art in various categories of information technology as they apply to education and training, including interactive videodisc, satellite communications systems, videotex, and artificial intelligence methods. These technologies and their potential are illustrated through case study examples. Policy recommendations are presented for governmental, industrial, and higher educational institution initiatives. 相似文献

Globalisation is a term too easily used without reference to the basic enabling role of technology. It is the interplay between available technology and the prevailing social processes, especially dominant institutional forms, which has essentially determined the long process of globalisation. This process has gone through phases exhibiting varying core characteristics as production, transport and communications technologies especially have interrelated with the institutional structures of nation states, military forces and firms especially. However, a general trend to geographical and tendentially global expansion has been constant, along with an intensification of information processing and communications capacity. The role of technology has been to enable this physical expansion culminating in globalisation, including the techno-industrial capacity that increasingly drove it through the construction of better and cheaper artefacts. 相似文献

BackgroundC4ST-1 catalyzes the transfer of sulfate groups in the sulfonation of chondroitin during chondroitin sulfate synthesis. Chondroitin sulfate consists of numerous copies of negatively charged sulfonic acid groups that participate in the nucleation process of biomineralization. In the present study, we obtained two CHST11 genes (PmCHST11a and PmCHST11b) which encoded the C4ST-1 and explored the functions of these genes in the synthesis of chondroitin sulfate and in the formation of the nacreous layer of shells.ResultsBoth PmCHST11a and PmCHST11b had a sulfotransferase-2 domain, a signal peptide and a transmembrane domain. These properties indicated that these genes localize in the Golgi apparatus. Real-time PCR revealed that both PmCHST11a and PmCHST11b were highly expressed in the central zone of the mantle tissue. Inhibiting PmCHST11a and PmCHST11b via RNA interference significantly decreased the expression levels of these genes in the central zone of the mantle tissue and the concentration of chondroitin sulfate in extrapallial fluid. Moreover, shell nacre crystallized irregularly with a rough surface after RNA interference.ConclusionsThis study indicated that PmCHST11a and PmCHST11b are involved in the nacre formation of Pinctada fucata martensii through participating in the synthesis of chondroitin sulfate. 相似文献

Abstract Corporate mergers and the consolidation of ownership in the American communications arena have long been sources of concern. U.S. regulatory and antitrust policy traditionally attempted to secure a “diversity of voices” structurally, largely through rules regarding ownership. Although the meaning of diversity was always problematic and undertheorized, the Federal Communications Commission long set ceilings on the numbers of broadcast outlets any single person or corporation could own and enacted cross-ownership rules such as a prohibition against a corporation owning a newspaper and broadcast outlets in the same market. These rules, and the FCC's authority to make them, were upheld, occasionally even compelled, by the federal appellate courts. In the last 20 years, however, legal trends, in conjunction with political developments, have undermined the diversity rationales behind ownership rules and associated structural regulations of mass media. Paradoxically, even as media corporations are becoming larger and presumably more powerful, ownership regulations are being rescinded or struck down. This article explains this history. It concludes with a suggestion that the First Amendment metaphor of a marketplace of ideas is misplaced, and of how our thinking about media ownership and diversity might be better served by the metaphor of a mixed media system. 相似文献

This article compares videotext in France and the United States, the two advanced industrialized countries where videotext was the most and least successful, respectively, in order to demonstrate how videotext as a techno-political project foreshadows the explosive growth of the Internet as the dominant global communications platform. It draws upon the theory of network effects, in combination with a comparative analysis of both the institutional settings for research and development and political discourse, to explain how the interaction between state, market, and culture shaped network development and policy outcomes. Data are drawn primarily from official policy documents and trade journals from the era. 相似文献

IntroductionWhile early commenting on studies is seen as one of the advantages of preprints, the type of such comments, and the people who post them, have not been systematically explored.Materials and methodsWe analysed comments posted between 21 May 2015 and 9 September 2019 for 1983 bioRxiv preprints that received only one comment on the bioRxiv website. The comment types were classified by three coders independently, with all differences resolved by consensus.ResultsOur analysis showed that 69% of comments were posted by non-authors (N = 1366), and 31% by the preprints’ authors themselves (N = 617). Twelve percent of non-author comments (N = 168) were full review reports traditionally found during journal review, while the rest most commonly contained praises (N = 577, 42%), suggestions (N = 399, 29%), or criticisms (N = 226, 17%). Authors’ comments most commonly contained publication status updates (N = 354, 57%), additional study information (N = 158, 26%), or solicited feedback for the preprints (N = 65, 11%).ConclusionsOur results indicate that comments posted for bioRxiv preprints may have potential benefits for both the public and the scholarly community. Further research is needed to measure the direct impact of these comments on comments made by journal peer reviewers, subsequent preprint versions or journal publications. 相似文献

Abstract The convergence of computer and communication technologies has made it feasible to establish a universal international communications network linking all mankind. The information flowing through this network constitutes an increasingly important element of world trade and a major source of future economic growth. However, governments are hesitant to allow the creation of a fully integrated international information network and tend to restrict at least some information flows for privacy, security, cultural, or economic reasons. This analysis argues that freer flows of information across national borders could help facilitate international economic growth and adjustment. Reasons used to justify policies that inhibit the integration of the world communication network or prevent transborder data flows are examined, and the implications of such restraints are discussed. Strategies for‐halting the proliferation of barriers to trade in communication and information services and for reducing existing obstacles are suggested. 相似文献
