概要	Axial coding is the second major analytical step in grounded theory analysis, performed after open coding. Introduced by Anselm Strauss and Juliet Corbin in 1990, it involves systematically re-examining and reorganising the many discrete codes generated during open coding by identifying a central (axial) category and mapping the causal conditions, contextual factors, intervening conditions, action-interaction strategies, and consequences that surround it. The goal is to move from a fragmented list of codes to a coherent relational structure that reflects how concepts interconnect in the data.	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.	Grounded Theory (GT) is a systematic qualitative research methodology in which theory emerges directly from data through iterative analysis, rather than being imposed before data collection. Developed by Barney Glaser and Anselm Strauss in 1967, GT prioritizes generating explanatory frameworks grounded in evidence.
