Thanks to the ready availability of political news today, informed citizens can protect and promote their own interests and the public interest more effectively. Or can they? Murray Edelman argues against this conventional interpretation of politics, one that takes for granted that we live in a world of facts and that people react rationally to the facts they know. In doing so, he explores in detail the ways in which the conspicuous aspects of the political scene are interpretations that systematically buttress established inequalities and interpretations already dominant political ideologies.

Constructing the Political Spectacle

Setting the Agenda: The Mass Media and Public Opinion

In this chapter we will be concentrating on one of the key processes in the ‘cultural circuit’ (see Du Gay et al., 1997, and the Introduction to this volume) – the practices of representation. The aim of this chapter is to introduce you to this topic, and to explain what it is about and why we give it such importance in cultural studies. The concept of representation has come to occupy a new and important place in the study of culture. Representation connects meaning and language to culture. But what exactly do people mean by it? What does representation have to do with culture and meaning? One common-sense usage of the term is as follows: ‘Representation means using language to say something meaningful about, or to represent, the world meaningfully, to other people.’ You may well ask, ‘Is that all?’ Well, yes and no. Representation is an essential part of the process by which meaning is produced and exchanged between members of a culture. It does involve the use of language, of signs and images which stand for or represent things. But this is a far from simple or straightforward process, as you will soon discover. How does the concept of representation connect meaning and language to culture? In order to explore this connection further, we will look at a number of different theories about how language is used to represent the world. Here we will be drawing a distinction between three different accounts or theories: the reflective, the intentional and the constructionist approaches to representation. Does language simply reflect a meaning which already exists out there in the world of objects, people and events (reflective)? Does language express only what the speaker or writer or painter wants to say, his or her personally intended meaning (intentional)? Or is meaning constructed in and through language (constructionist)? You will learn more in a moment about these three approaches. Most of the chapter will be spent exploring the constructionist approach, because it is this perspective which has had the most significant impact on cultural studies in recent years.

From Work to Representation

Projections of Power: Framing News, Public Opinion, and U.S. Foreign Policy

Social media platforms provide active communication channels during mass convergence and emergency events such as disasters caused by natural hazards. As a result, first responders, decision makers, and the public can use this information to gain insight into the situation as it unfolds. In particular, many social media messages communicated during emergencies convey timely, actionable information. Processing social media messages to obtain such information, however, involves solving multiple challenges including: parsing brief and informal messages, handling information overload, and prioritizing different types of information found in messages. These challenges can be mapped to classical information processing operations such as filtering, classifying, ranking, aggregating, extracting, and summarizing. We survey the state of the art regarding computational methods to process social media messages and highlight both their contributions and shortcomings. In addition, we examine their particularities, and methodically examine a series of key subproblems ranging from the detection of events to the creation of actionable and useful summaries. Research thus far has, to a large extent, produced methods to extract situational awareness information from social media. In this survey, we cover these various approaches, and highlight their benefits and shortcomings. We conclude with research challenges that go beyond situational awareness, and begin to look at supporting decision making and coordinating emergency-response actions.

Processing Social Media Messages in Mass Emergency: A Survey

This work-in-process literature review gives an overview of recent insight in the incorporation of social media in risk and crisis communication By marrying literature and examples of social media use with best practices in risk and crisis communication, this study demonstrates how communicators can embrace social media tools to better manage a risk or crisis Best practices in risk and crisis communication are summarized, examples of social media tools used to manage risks and crises are expounded, and recommendations for practitioners are provided to incorporate social media tools in risk and crisis communication

This study replicates and extends Heath and Abel's (1996) quasi-longitudinal analysis of the long-term impact of risk communication and emergency response measures. This study confirms and disconfirms some of the 1996 Heath and Abel conclusions. We found that because concern remains high that risk events are likely to occur and harm community safety, citizens are willing to become knowledgeable of emergency response measures. Such knowledge gives citizens a greater sense of control, which may translate into trust for industry and city emergency response experts. Support for the industry is increased by effective improvements in its operations. Long-term, community-relations programs may empower citizens with knowledge of what to do in the event an emergency occurs.
