Sintesi	Comparative Conversation Analysis (comparative CA) applies the rigorous micro-analytic methods of Conversation Analysis across two or more contrasting interactional settings, languages, cultures, or participant groups. It examines how the sequential organisation of talk — turn-taking, repair, adjacency pairs, and action formation — varies or remains stable across contexts, producing cross-contextual evidence about the architecture of human interaction.	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.
