Language Regulation in English as a Lingua Franca [PDF ebook] 
Focus on Academic Spoken Discourse

Language regulation has often been approached from a top-down policy perspective, whereas this book examines regulatory practices employed by speakers in interaction. With its ethnographically informed focus on language regulation in academic English as a lingua franca (ELF), the book is a timely contribution to debates about what counts as acceptable English in ELF contexts, who can act as language expert, and when regulation is needed.
