In the current era of globalisation, big-C Culture loses analytical purchase. However, research, as well as intercultural training and education, continues to take for granted a more or less fixed idea of culture. This volume updates intercultural communication, both its theory and its application, by utilising a theory of scales in order to understand how culture gets contextualised as speakers communicate and negotiate meaning with each other. As succinctly captured in the title of this volume, it is suggested that research can `downscale culture' analytically: culture might be, but also might not be, relevant in an interaction. The 14 chapters brought together here explore the possibilities of such downscaling from a wide range of core themes in intercultural communication studies and from various research traditions, including interactional sociolinguistics, critical geography, conversation analysis, critical discourse analysis, textual analysis, multimodal analysis and nexus analysis.
