b'This book demonstrates the power and distinctiveness of the contribution that sociolinguistics can make to our understanding of everyday communicative practice under changing social conditions.\xa0It builds on the approaches developed by Gumperz and Hymes in the 1970s and 80s, and it not only affirms their continuing relevance in analyses of the micropolitics of everyday talk in urban settings, but also argues for their value in emergent efforts to chart the heavily securitised environments now developing around us. Drawing on 10 years of collaborative work and ranging across disciplinary, interdisciplinary and applied perspectives, the book begins with guiding principles and methodology, shifts to empirically driven arguments in urban sociolinguistics, and concludes with studies of (in)securitised communication addressed to challenges ahead.'
