Introduction: Social media have become one of the leading health communication channels among the exponents of Health 2.0. Twitter has particularly noteworthy features for providing information quickly and easily. However, there is still controversy about the convenience of its use. Objectives: This paper aims to identify the main topics of health covered, the uses of Twitter in health communication and to characterize the valences (positive and negative) associated with each use. Methodology: To do that, we conducted a systematic review following PRISMA guidelines. Two databases (Web of Science and Pubmed) were searched, and 610 articles were retrieved. After removing duplicates, screening the titles and abstracts and assessing the full texts, 83 papers met the inclusion criteria. Results: The review identified five uses of Twitter: Conversation, Engagement, Information, Prevention, and Awareness, and it established the definitions of the positive and negative valences associated with each use. The most common uses found were Conversation and Engagement. Likewise, the two areas most studied were Public Health and Infectious Diseases. Conclusion: There is no consensus on the usefulness of Twitter as a tool for information or for generating debate, although the platform's effectiveness for measuring the impact of health campaigns was highlighted.

User behavior patterns when consuming and sharing information on social networks are analyzed, paying special attention to the effects of the type of presentation and the type of social network. As is common when analyzing activity on social networks, we used the experience sampling method, in which a group of volunteer participants are asked, at different times, a set of questions about their recent activity or experience. The sample consisted of 279 subjects. The results show that news requiring a greater effort is usually shared through closed networks, while in open networks there is a tendency to share more superficial information. No significant differences are found between the degree of reading of the news and the type of social network where it is shared. Moreover, the level of consumption does not influence the degree of reading of the shared material. The level of enjoyment of the news is found to influence its degree of reading. The differences between networks highlight that, on Facebook, the frequency of use influences the dynamics of consumption and sharing, with shared news being more emotional and useful. In contrast, in the case of Twitter, there is a greater preference for so-called soft information. [ABSTRACT FROM AUTHOR]

Currently, there is an important debate on how social networks have affected relations between organizations and their audiences: originally complementary –since organizations had full control over the messages that they sent to users, who were mere consumers of information–, they are now symmetric –since users produce and disseminate information about organizations on a global scale through social media–. Therefore, one of the main concerns of organizations when investing in social networks is to connect with their target audience, to have virality, greater visibility and scope. Likewise, neuromarketing is gaining significant importance when it comes to predicting user behavior through biometric measurements, so it can be an essential tool for developing content that engages organizations and their audiences. The main objective of this work is to conduct a theoretical review of the main scientific research on the effectiveness of neuromarketing as a tool to improve the emotional connection between organizations and users in social networks. Thus, the scientific literature on the object under study available on the Web Of Science has been extensively reviewed. The results of the analysis of the main researches in this field reveal the importance of neuromarketing: some of them agree that the communicative effectiveness between organizations and audiences in social networks depends more on sociology and psychology than on technology itself. Neuromarketing has also allowed to demonstrate the relevance of the so-called social influence in social networks: users tend to imitate the behaviors of others, under the premise that these actions reflect the appropriate procedure. That is, when a user sees that others in their environment comment or share a post, they tend to replicate that action in order to avoid the fear of being the only one who behaves differently.

Introduction: This article analyzes the influence of emotions on users' intention to share news about climate change on social media. Media consumption habits, previous attitudes towards the issue and social media uses and gratifications sought are considered as moderating roles. Methodology: An online, self-administered, questionnaire was submitted to a sample of undergraduate students from different courses and centers placed at Madrid region. Data were statistically tested following simple and multiple linear regression, simple and multiple logistic regression and simple and multiple ordinal regression models. Results and conclusions: It is concluded that fear and anger are the most influential emotions on users' intention to share a piece of news on social media. Information seeking, news internalizing and previous attitudes are identified as moderating factors. [ABSTRACT FROM AUTHOR]

The study focuses on ‘News Finds Me’ perception, i.e. the belief that users can stay informed enough without actively following traditional news media while relying on social media and personal contacts. The text analyses the influence between this perception and news consumption (“news internalising”) and sharing (“news externalising”). Uses & Gratifications sought (“information seeking”, “social interaction” and “impression management”) were considered as moderating variables. Survey based results (n = 96) show that ‘News Finds Me’ perception is positively correlated with news internalising but not with news externalising. It is thus concluded that the mere presence of the ‘News Finds Me’ perception does not encourage news sharing attitudes. The study also brings evidence to support a relationship between news internalising and news externalising habits, which influence each other mutually and can moderate other factors in news consumption and dissemination on social media. It is concluded that the presence of the ‘News Finds Me’ perception does not encourage news sharing attitudes. [ABSTRACT FROM AUTHOR]
