概要	Field-based conversation analysis (field CA) applies the rigorous sequential-analytic methods of conversation analysis to talk and interaction recorded in real-world settings — workplaces, clinics, classrooms, and public spaces — rather than to pre-existing corpora or laboratory data. By combining sustained fieldwork access with fine-grained transcript analysis, it reveals how social order is accomplished turn by turn in the actual environments where it matters.	Conversation Analysis (CA) is a qualitative research method that examines the fine-grained sequential structure of naturally occurring talk and social interaction. Developed by sociologists Harvey Sacks, Emanuel Schegloff, and Gail Jefferson in the 1960s and 1970s, CA investigates how participants in a conversation accomplish social actions — such as invitations, refusals, or diagnoses — through the precise moment-by-moment organisation of their talk, including turn-taking, sequence structure, repair, and recipient design.	Discourse analysis is a qualitative research methodology that examines how language, communication, and power shape meaning, identity, and social reality. Developed across linguistics, sociology, and psychology (particularly by Norman Fairclough and Jonathan Potter), discourse analysis goes beyond content to analyze language use as a social practice that constitutes and reflects power relations, ideologies, and social structures.
