Tóm tắt	Selective coding is the third and final analytic phase of grounded theory, in which the researcher systematically identifies one central or core category that integrates all other major categories developed during open and axial coding. The outcome is a coherent, data-grounded substantive theory that explains the main social process or phenomenon under study. First formalized by Glaser and Strauss (1967) and later elaborated by Strauss and Corbin (1990) and Kathy Charmaz (2006), selective coding transforms fragmented mid-level categories into a unified theoretical account.	Case study research is a qualitative research design that investigates a specific phenomenon, individual, group, organisation, or event in depth within its real-world context. Systematised by Robert K. Yin in 1984, it supports single-case and multiple-case designs and draws on multiple data sources — interviews, observation, documents, and artefacts — to build a rich, contextualised account of a bounded unit.	Narrative analysis is a qualitative research method, synthesised canonically by Catherine Kohler Riessman (2008), that examines how individuals storise their lived experiences and construct meaning through the telling. Drawing on life history, biographical, and narrative inquiry traditions, it treats the story itself — not just its content — as the unit of analysis, attending to temporal sequence, plot structure, and the social context in which a narrative is produced.
