概要	Comparative Content Analysis applies a shared coding framework to texts, documents, or media artifacts drawn from two or more groups, contexts, time points, or nations in order to identify similarities, differences, and patterns across those units of comparison. By holding the analytical lens constant while varying the comparison unit, it reveals how meaning, framing, or discourse differs across the cases under study.	Critical content analysis is a qualitative approach that examines texts, media, and documents not merely for manifest meaning but for how they construct, reinforce, or contest relations of power, ideology, race, gender, and class. Grounded in critical theory traditions, it asks whose interests a text serves, what voices are silenced, and how language and representation naturalise dominant worldviews. It combines systematic analytic rigour with an explicitly emancipatory or transformative research stance.
