This collage of Japanese washi papers is marked with quotes from an article by Heidi Gottfried about the intersectional oppression of women who migrate to Japan to do reproductive labour (nannies, maids, etc.) (Some quotes are abbreviated, and some come from authors Gottfried cites.)
The limitation of most intersectionality scholarship to a United States or Western focus leads Gottfried to discuss sociological methods for understanding the full complexity of gender, class, race and nation.
To model the intersection of those and more dimensions of privilege/oppression, I think it is also plausible to use mathematical approaches, ranging from multivariate statistics, to computational complexity theory (represented by the cluster of lines in the centre).
