This chapter examines the role mass media plays in the maintenance of social control and policy formulation and implementation in the Trump political era. First, an historical survey of mass media theory is presented and used as an analytic lens through which to identify that mass media has long been recognized as a powerful tool of social control or disruption and in public policy formulation and implementation. Second, this chapter explores the challenges posed to society and policy when a president uses mass media to spread misinformation and disinformation. Third, this chapter identifies the divisive nature of US political attitudes in the Trump era and how social media contributes to cleavage. Fourth, this chapter explores efforts by foreign actors, particularly Russian, to spread discursive and thus social chaos through disinformation campaigns in the United States and other western democracies. This chapter concludes that mass media has been both a divisive and uniting force, although the rise of social media and its susceptibility to manipulation poses a danger to social cohesion and effective public policy formulation and implementation. These factors have contributed to civil divisiveness and lack of policy clarity.

Purpose: The study explores how educators use mass media to sensemake their experiences in relation to school shootings.

Methodology/approach: The present chapter uses content analysis to analyze educator tweets and results from an anonymous online survey.

Findings: Twitter is used by educators in the aftermath of school shootings to sensemake the impact these events have on teaching and learning outcomes. Moreover, educators turn to Twitter to debate larger issues related to gun control and arming teachers. Collectively, educators remain committed to their institutions and students; however, they may struggle to meet the ever-changing demands of what it means to be a teacher in the post-Columbine educational landscape.

Research limitations: While providing a starting point for understanding how educators sensemake their experiences with mass media, there are limitations. The sample size was limited to 55 tweets and 40 survey respondents. Furthermore, researcher bias is a concern. Both researchers work in higher education and have experienced the emotional “heaviness” that comes with discussions of school shootings.

Originality/value: This study provides insights into how educators use mass media to sensemake school shootings as both content producer and consumer. Findings indicate that through the identification of patterns within educators’ sensemaking processes, educational institutions can develop better systems for processing the effect of gun violence on the teaching experience and within the classroom.

Purpose: Previous research has found that people’s trust in a source of information affects whether they will expose themselves to information from that source, pay attention to that source, and the likelihood that they will act on the information obtained from that source. This study tracked trends in levels of trust in different health information sources over time and investigated sociodemographic predictors of trust in these sources.

Methodology/Approach: Data were drawn from the Health Information National Trends Survey (HINTS), a nationally representative, cross-sectional survey of adults in the USA. Weighted percentages, means, and standard errors for trust in health information sources were computed using data from four iterations of the survey (2005, 2009, 2012, and 2013). Weighted multivariable logistic regression models were employed to investigate associations between sociodemographic variables and level of trust in health information sources using HINTS 2013 data.

Findings: Trend analyses revealed declining trust in “traditional” mass media channels, such as television and radio, for health information and consistently high trust in interpersonal sources, like physicians, over the past decade. Regression analyses showed that those with more education (ORs 2.93–4.59, p < 0.05) and higher incomes (ORs 1.65–2.09, p < 0.05) were more likely to trust the Internet for health information than those with less education and lower incomes. Non-Hispanic Blacks and Hispanics were more likely to trust mass media channels in comparison to Non-Hispanic Whites (ORs 1.73–2.20, p < 0.05).

Implications: These findings can be used to inform the strategic selection of channels for disseminating health information to certain demographic groups.

Walter Lippmann in his 1922 classic “Public Opinion” noted that “the news media are a primary source of those pictures in our heads about the larger world of public affairs, a world that for most citizens is “out of reach, out of sight, out of mind.” Indeed, among the different roles that the mass media performs is one of an information provider and interpreter of world events and policy decisions. The power of the mass media to mould public opinion on issues of national and international significance is well documented. Our knowledge and priorities about public affairs are based on what the media decides to feed us with. In this context, the present chapter seeks to analyze the crucial role essayed by the mass media in ensuring human security by promoting favorable public opinion toward the cause of nuclear nonproliferation and disarmament. S. Rashid Naim enunciates in “Nuclear Proliferation in South Asia” that a nuclear attack between India and Pakistan even limiting itself to military targets would cause approximately 577,000 deaths in Pakistan and 604,000 deaths in India apart from substantial number of injuries and destruction of property. The knowledge about this impending havoc should reach the grassroots level and this can be accomplished only by the mass media. With global efforts being channelized toward nonproliferation of nuclear weapons, the media and its trend-setting abilities can be harnessed to enlighten the average public about the disasters of a nuclear war. As the role of the mass media becomes more prominent in managing conflicts all over the world, the time is ripe to utilize its immense powers to dilute the level of possible nuclear clashes. A more proactive role of the media is envisioned through the establishment of a “global communication center” dedicated to the publication and broadcast of information advocating the cause of total nuclear disarmament. This center will be the locus of information dissemination and advocacy directed toward nations that possess nuclear weapons and those that are likely to get their hands on them in the near future. While the mass media is certainly not the only actor in the process of nuclear disarmament, it can be a decisive force for nations to choose between “atom for peace” or “atom for war.”

The present paper analyzes the implementation of Open Digital Television (Televisión Digital Abierta or TDA) in Argentina. It takes up a sociotechnical standpoint and considers TDA as a public policy designed to foster social inclusion.

The ideas presented in this paper are derived from a sociotechnical perspective, both at a theoretical and at a methodological level. The main postulates of this perspective are based on constructivist criteria; they explain outcomes as a result of the constant interplay of technical and social realities. Thus, this relation is intrinsic and continuous. We work with the concept of technology in its broadest sense. That is to say, TDA is not seen as just a mass communication infrastructure, but as a technology which involves knowledge, production practices, and content broadcasting, as a result of the interrelation of cultural, political, social, economic, scientific, and technological factors. The study of TDA in Argentina as a public policy for social inclusion shows how the constant sociotechnical interrelations have to be taken into account (technical standard, antenna features, social actors involved, produced content, etc.) throughout the whole process, from the conception and design of public policies to their implementation, but mainly at the stage of results analysis.

We concluded that throughout the implementation of the TDA public policy, a determinist view of technology prevailed. This can be seen in relation to both the role of television as a medium for social inclusion and the actions regarding the role of the user. The idea of viewer in the traditional sense prevailed over the idea of an active user. This stage provides significant data to assess the range and the limitations of the current public policy, and to think of improvements to implement in the future. These observations suggest a new challenge lying on the horizon: to construct a new concept of television; that is, to analyze TV as a social actor that is crucial for social inclusion rather than simply a medium of mass communication.

The sociotechnical perspective sheds light on the actors involved in the development, implementation, and production of a public policy designed for social inclusion. It focuses both on the government plan and the usage practices of the users themselves. The approach we propose for the study of the relation between technology and public policy is consistent with the notion of an active government.

The value of this paper lies in its theoretical and methodological approach, since a sociotechnical analysis grounded on relativism is a different view to the one that is dominant in studies in the field of communication and public policies. This view offers innovative insights into the problems regarding TDA by exploring the interrelations between actors and the power relations embedded in the public policy.
