Today's technologies offer many opportunities for communication and for developing the social, political and economic environments. Social media is one of the channels highly used for personal and business communication in our informational society. However, the various facets of the social media may not be employed in the same manner for the needs of the individual as they are for the needs of the businesses aiming to develop in the tourism sector. This paper aims to identify which of the social media platforms are appropriate for being used for personal purposes and which are more suitable for developing a business in tourism, amongst the users of social media. The paper bases its conclusions on a survey applied on a sample of Romanian young people (18 – 35 years old) involved in tourism business environment, as according to research in the field such as Lenhart, Purcell, Smith and Zichur (2010) and Cabral (2011) this is the most active segment in social media. The findings presented in the paper result from the analysis of the survey responses and they indicate that all four types of social media platforms taken into account: social networks, blogs, micro-blogs and video file sharing platforms are used for both personal and business purposes. However, inside each of the four types of platforms surveyed there were noticed certain preferences, from the point of view of users' interests in communication: personal purpose communication or business in tourism purpose communication.

"The widespread adoption of smartphones has led to an explosion of mobile social media data, more than a billion messages per day that continuously track location, content, and time. Social Media in the Contemporary City focuses on the effects of social media on local communities and urban space in a variety of political and economic settings related to social activism, informal economic activity, public art, and global extremism. The book covers events ranging from Banksy art installations, mobile food trucks, and underground restaurants, to a Black Lives Matter protest, the Christchurch mosque shootings, and the Pulse nightclub shooting. The interplay between urban space, local community, and social media in each case study requires diverse methodologies that are both computational (i.e. machine learning, social network analysis, and natural language processing) and ethnographic (i.e. semi-structured interviews, thematic analysis, and site analysis). The book views social media not as a replacement for local community or urban space but rather as a translation of the uses and meanings of all three realms. The book will be of interest to students, researchers, and instructors in a number of disciplines including urban design/planning, media studies, geography, and communications"--

E-government aims to enhance the interaction between citizens, business, and government. Recently, the term open government is increasingly used to emphasize the importance of co-creation in governmental issues. In this study, the social media activities of the municipalities of North Rhine-Westphalia, Germany, are investigated with regard to the topic "open government" as one pillar of e-government. The findings show that user interaction is mostly represented through likes and shares and rarely by comments. A topic detection of the posted content reveals that different terms are covered by the municipalities and shows that open government is getting more and more diverse in recent years. The number of posts is still increasing each year on the social media platforms Facebook and Twitter, but the topic of open government is still a peripheral phenomenon.

The use of social media has spread through many aspects of society, allowing millions of individuals, corporate as well as government entities to leverage the opportunities it affords. These opportunities often end up being exploited by a small percentage of the user community who use it for objectionable or unlawful activities; for example, trolling, cyber bullying, grooming, luring. In some cases, these unlawful activities result in investigations where swift retrieval of critical evidence required in order to save a life. This paper presents a proof of concept (PoC) framework for social media user attribution. The framework aims to provide digital evidence that can be used to substantiate user activity in live triage investigations. This paper highlights the use of live triage as a viable technique for the investigation of social media activity, contextualizing user activity and attributing actions to users. It discusses the reliability of artefacts other than the communications content as a means of drawing inferences about user social media activity, taking into account the proportionality and relevance of such evidence

Disinformation and so-called fake news are contemporary phenomena with rich histories. Disinformation, or the willful introduction of false information for the purposes of causing harm, recalls infamous foreign interference operations in national media systems. Outcries over fake news, or dubious stories with the trappings of news, have coincided with the introduction of new media technologies that disrupt the publication, distribution and consumption of news -- from the so-called rumour-mongering broadsheets centuries ago to the blogosphere recently. Designating a news organization as fake, or der Lügenpresse, has a darker history, associated with authoritarian regimes or populist bombast diminishing the reputation of 'elite media' and the value of inconvenient truths. In a series of empirical studies, using digital methods and data journalism, the authors inquire into the extent to which social media have enabled the penetration of foreign disinformation operations, the widespread publication and spread of dubious content as well as extreme commentators with considerable followings attacking mainstream media as fake.

The search for meaning is an essential human activity. It is not simply about agreeing on some definitions about the world, objects, and people, but is also an ethical process of opening up to others and to the world to find new possibilities. Social media corporations commodify our search for meaning by defining the parameters through which we can experience meaningfulness. This new context of meaning requires rethinking the relationships between language, software, and the psyche. Langlois uses case studies of popular social media platforms (including Facebook, Twitter, and Amazon, among others) to revisit traditional conceptions of meaning. She develops a new theoretical and methodological framework drawing from post-Fordist theories, software studies, critical theory, and relational psychoanalysis to examine the technical mediation and commodification of the psychic, cultural, and linguistic processes involved in the search for meaning.

Social media influencers have become increasingly important in the last years. Influencers, that is, individuals with a large number of followers on social media, filter information, advertise products and services, offer advice, and promote political opinions with a significant impact on a broad audience. Nevertheless, their actions have remained largely unregulated and overlooked in the literature. This paper offers an exploratory analysis of this phenomenon and delves into the regulatory challenges resulting from the activity of social media influencers. It fills an important gap in the academic literature by providing an interdisciplinary analysis of a phenomenon with growing societal relevance. Given their large audiences, influencers are very effective not only at creating online engagement for the companies that employ their services, but also at manipulating their followers' opinions and transactional behavior, as the latter do not always distinguish between genuine and sponsored marketing advice. Although advertising regulations include endorsements made on Instagram or Youtube by 'prosumers', influencers appear to disregard these regulatory limits and national regulators have experienced difficulties in safeguarding their enforcement. In this context, average social media users are at an ever-greater risk of falling prey to inconspicuous commercial interests. This paper also introduces an interdisciplinary project that brings together insights from media studies, law, communication science and empirical legal studies, dealing with themes such as social media, influencer marketing, free speech, gig work, platform governance, and consumer protection.
