概要	Comparative Institutional Ethnography (CIE) extends Dorothy Smith's institutional ethnography to two or more institutional settings, revealing how texts, ruling relations, and coordinated work practices operate across different organizational contexts. By holding the standpoint of workers or clients constant while varying the institutional site, CIE exposes both the shared ideological mechanisms and the local divergences that shape everyday experience within institutions such as hospitals, schools, welfare agencies, or courts.	Comparative qualitative content analysis (comparative QCA) applies a systematic, category-driven reading of texts or documents across two or more cases, groups, time periods, or cultural contexts, with the explicit goal of identifying similarities, differences, and patterns that emerge from the comparison. It combines the interpretive rigour of qualitative content analysis with a structured comparative logic, making it valuable for cross-national policy research, media studies, and any inquiry that requires principled comparison of meaning across contexts.
