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

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

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 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

The September 11 attack on the Pentagon and the World Trade Center reveals, among other things, a colossal failure of intelligence and radical deficiencies in our understanding of communications in the modern world. The history of nations and the history of communications are continuous, though contradictory, since the eighteenth century, and those continuities and contradictions are revealed by way of analysis of September 11 and its aftermath. 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

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

The community of practice learning theory (Lave and Wenger, 1991) can be credited with establishing the social basis of learning, viewing it as occurring through participation in social practices and activities. However, it remains silent on the cognitive content of what is learned by participants in a community of practice. Nor does it address explicitly the role of individuals in the knowing process. Individuals are merely depicted in terms of a desire to belong to a community, progressing from a peripheral participation position to a more central one. The aim of the present paper is to assess the contribution of Lave and Wenger's (1991) practice theory for educational and other learning social settings. In a schooling context, for instance, Lave and Wenger's (1991) account of learning would imply that what students learn at school is how to relate and belong to the school community. By reducing learning and knowing to participation, and by displacing cognition from individuals to anonymous practices, the practice-based epistemology ignores the significant corpus of content knowledge (such as curriculums) and ascribes too passive a role to individuals and glosses over their differentiated access to resources for changing practices and their differentiated efforts in their social and cognitive development. The present paper suggests an approach to knowledge that takes into account the various facets of knowledge, that is, knowledge as knowledge-productive practices, as content, and as relation to a knowing subject, at the same time preserving the sociality of knowledge and learning. 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

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

IntroductionThe data on the coronavirus disease (COVID-19) in solid-organ transplant recipients (SOTRs) in Croatia is unknown. The aim of this study was to analyze the seroprevalence of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) in Croatian SOTRs.Materials and methodsFrom 7 September to 27 November 2020 (beginning of the second COVID-19 pandemic wave), a cross-sectional screening for COVID-19 was performed in the adult outpatient liver (LTRs; N = 280) and kidney transplant recipients (KTRs; N = 232). Serum samples were initially tested for SARS-CoV-2 IgG antibodies using a commercial enzyme-linked immunosorbent assay (ELISA; Vircell Microbiologists, Granada, Spain). All positive samples were confirmed using a virus neutralization test (VNT). Data on risk exposure and COVID-19 related symptoms were collected using a questionnaire.ResultsThe transplanted cohort’s seroprevalence detected by ELISA and VNT was 20.1% and 3.1%, respectively. Neutralizing (NT) antibodies developed in 15.6% of anti-SARS-CoV-2 ELISA IgG positive SOTRs. The difference in seropositivity rates between LTRs and KTRs was not statistically significant (ELISA 21.1% vs. 19.0%, P = 0.554; VNT 3.6% vs. 2.6%, P = 0.082). Overall VNT positivity rates were higher in patients who reported participation in large community events (5.9% vs. 1.0%; P = 0.027) as well as in patients who reported COVID-19 related symptoms in the past six months. In addition, symptomatic VNT positive patients showed significantly higher (P = 0.031) NT antibody titers (median 128, interquartile range (IQR) = 32-128) compared to asymptomatic patients (median 16, IQR = 16-48).ConclusionsThis study showed that 15.6% of anti-SARS-CoV-2 ELISA positive Croatian SOTRs developed NT antibodies indicating protective immunity. Further studies are needed to determine the dynamic of NT antibodies and COVID-19 immunity duration in immunocompromised populations such as LTRs and KTRs. 相似文献

The images of America exported by entertainment and information media companies have created very high expectations in foreign audiences. Some recipients overhearing American media want to immigrate to the US and/or study in Western universities. In the process, a few of them encounter difficulties deceiving their high expectations. Their frustrations have been exploited by some fanatic ideologues for their own agendas, resulting in anti-American terrorism. The American media should be aware of the unintended consequences of their global exhibition of media, and more careful attention should be given to the way immigrants or graduate students sojourning in the US live their day-to-day encounters. 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

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

This study summarizes prior reviews of new media and Internet research, and the growth of the term Internet in academic publications and online newsgroups. It then uses semantic network analysis to summarize the interests and concepts of an interdisciplinary group of Internet researchers, as represented by session titles and paper titles and abstracts from the 2003 and 2004 Association of Internet Researchers conferences. In both years, the most frequent words appearing in the paper abstracts included Internet, online, community, social, technology, and research. The 2003 papers emphasized topics such as the social analysis/research of online/Internet communication, community, and information, with particular coverage of access, individuals, groups, digital media, culture; role and process in e-organizations; and world development. The 2004 papers emphasized topics such as access; news and social issues; the role of individuals in communities; user-based studies; usage data; and blogs, women, and search policy, among others. 相似文献

AbstractSocial media and news use arguably contribute to the prevalence of contentious politics because individuals may express dissent through their social networks as they consume news. This study seeks to test whether individuals might be more open to political persuasion in this context, especially if they are exposed to political disagreement or discuss politics in a civil manner. Relying on survey data from the UK, results based on a moderated moderation model show that (a) social media news use predicts political persuasion on social media (direct effects) and, (b) discussion disagreement and civil reasoning moderate this relationship in two-way and three-way interactions. 相似文献
