概要	Critical institutional ethnography (CIE) combines Dorothy Smith's institutional ethnography with an explicit critical theory lens to investigate how ruling relations, texts, and institutional discourses reproduce inequality and power asymmetries. Starting from the lived experiences of people positioned within or subordinated by institutions, CIE traces how abstract institutional processes coordinate everyday life and subjects those processes to normative critique aimed at social transformation.	A critical case study is a case study design in which the researcher deliberately selects a case that is strategically important for testing, confirming, challenging, or extending an existing proposition, theory, or policy claim. Rather than choosing a typical or representative case, the researcher argues that if the finding holds here — in this most-likely, least-likely, or paradigmatic instance — it can reasonably be expected to hold more broadly. This purposive logic transforms a single case into a powerful analytical tool.
