Title of thesis:

How linguists’ writing changes: a case study of linguists’ diachronic construal of theoretical entities and epistemic stance enactment

Description of thesis research:

My thesis focuses on the writing development of scholars in the area of linguistics, with particular interest in their use of language strategies for construing theoretical entities and enacting epistemic stance. Theoretical entities are the “things” that scholars theorize about and one of my aims is to explore how their representation evolves throughout specific linguists’ writing trajectories. I also aim to explore specific scholars’ diachronic enactment of epistemic stance, that is, the degree of certainty with which they make knowledge claims over time. In both aspects, the key questions to address are, first, whether there is any recognizable pattern of diachronic variation, and secondly, what language resources and strategies are most directly implicated. I use corpus-based and text analytical tools in pursuing an answer to these questions.
