概要	Net-Map is a participatory, paper-based tool developed by Eva Schiffer for collecting social and influence network data while helping participants reflect on the networks they are part of. Sitting around a large sheet, participants name the actors involved in a goal or process, draw and label the links between them by type (for example funding, information, or command), and then stack physical 'influence towers' — disks or blocks — beside each actor to show how much power that actor holds. The session produces both a rich qualitative discussion and a quantitative, analyzable network with weighted nodes and typed, directed ties.	The ethnographic interview, formalized by James Spradley, is a deliberately staged conversation whose goal is to discover how an insider categorizes and talks about their own cultural world rather than to test the researcher's categories. It proceeds through a developmental research sequence of question types — broad grand-tour questions, fine-grained descriptive questions, structural questions that probe how knowledge is organized, and contrast questions that surface the distinctions informants draw between terms. The point is not a list of facts but a reconstructed map of meanings expressed in the informant's own native terms.
