خلاصه	Longitudinal Institutional Ethnography (longitudinal IE) combines Dorothy Smith's sociology of standpoint — institutional ethnography — with repeated data collection over time to trace how institutional texts, relations, and ruling practices shape people's everyday lives across a temporal span. By revisiting the same participants, settings, or documents at multiple time points, it reveals how institutional coordination evolves, accumulates, or intensifies over weeks, months, or years.	Participatory Institutional Ethnography (PIE) combines Dorothy Smith's institutional ethnography with participatory research principles, positioning community members or service users as co-researchers who investigate how institutional relations, ruling texts, and organizational practices shape and often constrain their everyday lives. The approach aims both to produce knowledge about institutional coordination and to generate actionable change through collaborative inquiry.
