Globalization as a phenomenon was seen by scholars as a compression of the world, where the world comes together as a global village in thought and in action. Arjun Appadurai, in his theorization of globalization, challenges this view. He argues that globalization is primarily disjunctive, scalar, and contextual. He defines five basic landscapes that are about people and their migration (ethnoscapes), technology (technoscapes), media (mediascapes), ideology (ideoscapes) and finance (finanscapes). Globalization, according to Appadurai, occurs at the points of rupture and disjuncture between these different landscapes. In this context he defines “imagination as a social practice” and situates the work of imagination at the center of all globalization processes. Media flows decidedly play a large role in shaping the imagination, therefore mediascapes are critical to the understanding of globalization in any given context. Similarly, the flows of capital, of people, of ideologies and technology help create new imagined worlds that are fluid and capable of producing a “globally variable synesthesia.” That is, one type of imagined world can trigger similar imaginaries in other parts of the world, yet they possess different shapes and forms. Appadurai’s theorization was later criticized for presenting too optimistic a view of globalization, for ignoring its dark side. So, in his later work Appadurai explores the “dark” side of globalization. In Fear of Small Numbers, he addresses the widespread global violence against minorities and uses Freud’s “anxiety of incompleteness” to explicate the majority group’s predatory behavior. Globalization has deepened this behavior and thought because it intensifies the possibility and related fear of the majority morphing into the minority and vice versa. Collective group identities, therefore, are forever under threat as “volatile morphing” becomes a reality brought about by rapid global migrations across national boundaries. Appadurai’s later work also points in the direction of hope by presenting the idea of grassroots globalization which is happening alongside the pervasive violence. Grassroots globalization is the idea of globalization from below that is done by non-governmental organizations and transnational advocacy networks that work toward redressing lack of access, injustice and inequity. Appadurai also offers scholars a new framework for how to do globalization research which is not fixated on its “internationalization” but is focused on questions and is inclusive of other worldviews and approaches from around the world.
Political economy approaches examine the power relations that comprise the production, distribution, and exchange of resources. They are distinguished from economics by a deeper concern for history, the social totality, moral philosophy, and praxis. Numerous schools of thought mark the political economy approach including early conservative, communitarian, and Marxian perspectives. Today, neoconservative, institutional, neo-Marxian, feminist, environmental, and social movement based approaches offer a wide variety of political economies. Communication scholars have drawn on political economy approaches to carry out research on media technologies, including broadcasting, telecommunications, and computer communication. In doing so they have developed distinctive geographic perspectives covering North America, Europe, and the less developed world. Political economy approaches are built on specific philosophical assumptions including a range of epistemologies that, on one end of a continuum, accept the reality of both concepts and observations and, at the other, claim that all explanations can be reduced to one essential cause, such as the economy or culture. Political economy approaches also range from perspectives that emphasize social change, social processes, and social relations to those that focus on social structures and institutions. Political economy approaches tend to concentrate on three processes that make up the main starting points for political economy research on media technologies. Commodification is the process of transforming things valued for their use into marketable products that are valued for what they can bring in exchange. This can be seen, for example, in the process of turning a story that friends tell one another into a film or a book to be sold in the marketplace. Spatialization is the process of overcoming the constraints of geographical space with media and technologies. For example, social media surmounts distance by bringing images of world events to every part of the globe and companies use media technologies, now often comprised of cloud computing, big data analytics, the Internet of Things, and telecommunications networks, to build global supply chains. Finally, structuration is the process of creating social relations, mainly those organized around social class, gender, and race. With respect to social class, political economy approaches describe how access to the mass media and new communication technologies is influenced by inequalities in income and wealth, which enable some to afford access and others to be left out. Political economy approaches are evolving in response to challenges from cultural studies approaches. Political economies of media technologies are now placing greater emphasis on international communication, on communication history, on standpoints of resistance, on new media technologies, and on new media activism.
Multicommunication means interacting with several people separately but at the same time. Usually multicommunication refers to parallel conversations enabled by communication technologies. The essential element is interactivity: in multicommunication, several mutual, two-way interactions are managed between people. A few adjacent concepts related to multicommunication have also been used in the literature, including multitasking, media or electronic multitasking, polychronicity, and polychronic communication. Research interest in multicommunication is growing. Whereas the nascent phases of multicommunication research were largely concerned with observing the manifestation and characteristics of the multicommunication phenomenon, defining the concept of multicommunication, and differentiating multicommunication from similar concepts, contemporary research has spread out in many directions. Three main topics can be distinguished in multicommunication research: motivators of multicommunication, management of multicommunication, and consequences of multicommunication. The research contexts for multicommunication to date have been predominantly limited to working life. Very few studies have actually focused on family communication, contacts between friends, or other contexts involving communication in private life. For their preferred methods in empirical multicommunication research, most scholars to date have used surveys, interviews, diaries, critical incidents, and other self-reports, as well as laboratory experiments. Researchers are beginning to learn quite a bit about the motivators and consequences of multicommunication, as described by employees in the workplace. Multicommunication research would thus benefit from the observation and analysis of natural communication found in actual contexts, settings, and relationships.
