Based on the commonly held assumption that we now live in a world that is 'on the move', with growing opportunities for both real and virtual travel and the blurring of boundaries between previously defined places, societies and cultures, the theme of this book is firmly grounded in the interdisciplinary field of 'Mobilities'. 'Mobilities' deals with the movement of people, objects, capital, information, ideas and cultures on varying scales, and across a variety of borders, from the local to the national to the global. It includes all forms of travel from forced migration for economic or political reasons, to leisure travel and tourism, to virtual travel via the myriad of electronic channels now available to much of the world's population. Underpinning the choice of theme is a desire to consider the important role of languages and intercultural communication in travel and border crossings; an area which has tended to remain in the background of Mobilities research. The chapters included in this volume represent unique interdisciplinary understandings of the dual concepts of mobile language and border crossings, from crossings in 'virtual life' and 'real life', to crossings in literature and translation, and finally to crossings in the 'semioscape' of tourist guides and tourism signs. This book was originally published as a special issue of Language and Intercultural Communication.

'Intercultural dialogue', as a concept and ideology in the European Union, stimulates a rational 21st century society where people can engage in (intercultural) communication on a global scale, and can do so openly and freely in conditions of security and mutual respect. Intercultural dialogue connotes dialogic communication that is peaceful, reconciliatory, and democratic. Yet the term and its accompanying rhetoric belie the intercultural communicative undercurrents and their manifestations that people encounter in their daily lives. The research-informed chapters in this book, which are situated in international contexts, provide more nuanced understandings, and many even challenge this non-critical ideology by suggesting that the concept of intercultural dialogue is inoperable and problematic under the present conditions of globalisation and migration, where there exists conflict, vulnerability, and instability. The different theoretical perspectives and analyses presented by the authors are a reminder that researchers in the field of intercultural communication require robust and appropriate theories, methods, and pedagogies in order to research these complex conditions and contexts, particularly where different languages and identities are present. The book is also a reminder of how context and power both (re)shape and contest the central tenets of intercultural dialogue-in particular, of who speaks for whom, when, how, and under what circumstances and conditions.
