Mentoring and Co-Writing for Research Publication Purposes addresses a major gap in our knowledge of how doctoral supervision relationships in the sciences are enacted as writing pedagogy. Based on a multiple-case study of three student-supervisor pairs in environmental sciences, neurosciences and biochemistry as they each prepared a research article for publication, this book offers a finely grained and studied analysis of the role of joint authorship in scaffolding research writing development in the sciences. This book: • Critically engages with a range of approaches to studying doctoral education and writing practices. • Formulates a wide-lens methodology to capture, analyse and interpret the multimodal interactions between co-authors and their evolving text. • Describes writing-oriented supervision meetings in terms of their social and spatial configurations and analyses the roles of supervisor and student visà- vis each other and their evolving text. • Builds theory on how supervisors enculturate their students into the intricate social negotiations at the heart of academic peer review. • Describes how certain genre conventions and textual patterns both emerge from and contribute to the observed writing practices. Paving the way for future research into co-authoring practices by supervisors and students in postgraduate settings, Mentoring and Co-Writing for Research Publication Purposes is a valuable resource for researchers and advanced students interested in doctoral supervision and writing for research publication purposes.
