The constant demands of citizens to be informed in real time have made Twitter an ideal tool for mass use. This social network has originated a new user of social communication, and is used to present public images and appeal to the population, at the same time that it is displacing the pre-eminence of traditional communication media. During the national strike in Ecuador in October 2019, alternative and conventional media used this platform to inform, generate debate, carry out calls and mobilizations, and position perspectives. This study analyzes the tweets and hashtags published on the most viral days of the strike. A mixed methodology was applied, i.e., qualitative and quantitative. The techniques applied were discourse analysis and the systematic review of each hashtag. The sample was taken from the hashtags published by traditional and alternative media from October 3 to 13. As the main result, it was concluded that the published hashtags had a high impact on informing users and, to a certain extent, on the calls that were made.

Using a comprehensive dataset from 2008 to 2018, we study the role of different information sources (traditional media, new media, and social media) on information spread in the Chinese stock market. The findings reveal varied leading and lagging relationships in the timeliness of fraud information disclosure from three media types and the most significant impact from social media. The results on price synchronicity reveal the significantly negative influence of all media coverages; among them, the impact of new media is in the first position, social media is in second place, and traditional media is the smallest. Furthermore, this influence is more pronounced for firms that are not audited by Big 4 auditors or with lower institutional ownership. In summary, we reveal the different effects of three media channels around fraud events and price synchronicity in China.

Background This article aims to revisit the role of digital media in acquiring campaignspecific information. Analysis We use datasets from the Making Electoral Democracy Work project that include campaign-specific questions to analyze six regions in three democracies (Canada, Spain, and France). Conclusion and implications Results demonstrate that voters have a moderate level of campaign-specific knowledge and that traditional media are, at first glance, more useful to acquire political information. Nevertheless, when in interaction with partisanship, traditional media display a surprisingly greater selection bias effect and appear less useful to acquire information. We thus argue that digital media are in fact not more vulnerable to potential echo chambers that would lead to a homogenous information environment.

How do managers perceive and use media? Media richness theory (MRT) appears to provide persuasive answers to this, but does it work when electronic media is used? Surveys of Japanese managers showed that the perceptions of media, including electronic media, did not contradict MRT. But, even so, the use of rich media was found to be influenced more strongly by whether the media was traditional or electronic, with respect to organizational interpretation of its environment. The perception and use of electronic media may not correspond, though they have generally been assumed to do so.

The media play an important role in risk communication, providing information about accidents, both nearby and far away. Each media source has its own presentation style, which could influence how the audience perceives the presented risk. This study investigates the explanatory power of 12 information sources (traditional media, new media, social media, and interpersonal communication) for the perceived risk posed by radiation released from the damaged Fukushima nuclear power plant on respondents' own health and that of the population in general. The analysis controlled for attitude toward nuclear energy, gender, education, satisfaction with the media coverage, and duration of attention paid to the coverage. The study uses a large empirical data set from a public opinion survey, which is representative for the Belgian population with respect to six sociodemographic variables. Results show that three information sources are significant regressors of perceived health-related risk of the nuclear accident: television, interpersonal communication, and the category of miscellaneous online sources. More favorable attitudes toward nuclear power, longer attention to the coverage, and higher satisfaction with the provided information lead to lower risk perception. Taken together, the results suggest that the media can indeed have a modest influence on how the audience perceives a risk.

OBJECTIVE: This review was conducted to assess the role of social media in oral health promotion by reviewing the perspectives and evaluation methods of previous related studies. MATERIALS AND METHODS: The preferred reporting items PRISMA checklist was used to structure this review. Key search terms were identified to examine databases including PubMed, Web of Science and Embase. Manual searches in relevant journals and materials were also conducted in the meantime. RESULTS: A total of 640 articles were identified after multi-source screening and duplicates removing, and finally 19 original studies published before April 2020 met the inclusion criteria. These studies mainly cover the fields of dentistry education and research, clinical treatment, and preventive dentistry. Both traditional and new-type social media have advantages and focuses, as well as biased information. Detailed assessment methods and indicators are classified into several groups, which could be selected to use in future research. CONCLUSIONS: The application of social media in oral health promotion is becoming popular with the development of information technology. The broader use in the future, covering dentistry, mass health education, both long-term and short-term treatments of additional clinical content, requires further evaluation and supervision in online information sharing process. The reasonable selection of methods and indicators according to different topics and preference is of great importance.

How do social media differ from traditional media in their coverage of disruptive technological change? We explore how two entrants transforming the personal transportation and accommodation sectors are covered in social and traditional media. Using content analysis, we conclude that these two forms of media differ substantially. Traditional media is focused on how the two entrants affect society and their respective sectors at large, whilst social media instead function as accelerators for the entrants as they receive predominantly positive coverage. Therefore, our findings suggest that the rise of social media may accelerate the growth of disruptive innovations which can, in turn, reduce the window for response.

Social media offers an approach to communicating which enforces many of the key principles of effective risk communication, such as timeliness and openness. However, the use of social media is not without its challenges. To ensure effective messages are communicated to the public during times of food risk/crises, it is imperative that sources of such information are cognisant of the role played by both traditional and social media. This paper discusses these issues and highlights some results from the recent European Commission-funded FoodRisC project - Perceptions and communication of food risk/benefits across Europe.

Engaging and retaining adolescents in research studies is challenging. Social media offers utility for expanding the sphere of research recruitment. This study examined and compared traditional and Facebook-based recruitment strategies on reach, enrollment, cost, and retention. Substance users aged 13-17 years were recruited through several methods, including social media, a study website, fliers, talks in schools, bus ads, and referrals. Study involvement included a one-time visit and semiannual follow-up surveys. 1265 individuals contacted study personnel; 629 were ineligible; 129 declined; and 200 participants enrolled. Facebook drew the greatest volume but had a high rate of ineligibles. Referrals were the most successful and cost-effective ($7 per enrolled participant); school talks were the least. Recruitment source was unrelated to retention success. Facebook may expand recruitment reach, but had greater financial costs and more ineligible contacts, resulting in fewer enrollees relative to traditional interpersonal recruitment methods. Referrals, though useful for study engagement, did not provide a differential benefit in terms of long-term retention.
