This volume focuses on the connection between participation constellations and identity construction as a specific, yet under-researched problem of text and media linguistics. It assembles empirical analyses of a wide range of corpora, ranging from naturally occurring talk-in-interaction over TV series and social media discourse to the linguistic landscapes of Namibia. In addition to insights into dynamic participation and identity constellations in the respective corpora, the articles develop new theoretical concepts and categories. This volume is of interest to advanced students and scholars in linguistics, media studies and sociology alike.
