Perhaps you should try some spelling variations:
"political anthropology" » "biological anthropology", "physical anthropology", "theological anthropology"
"criminal anthropology" » "social anthropology", "physical anthropology"
"visual anthropology" » "social anthropology", "physical anthropology"

You may be able to get more results by adjusting your search query.

• If you are trying to use Boolean operators, they must be ALL CAPS: (((((("visual anthropology") OR ("medical anthropology"))) OR ((("criminal anthropology") OR ("political anthropology"))))) OR ("cultural anthropology")).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((((\"visual anthropology\") or (\"medical anthropology\"))) or (((\"criminal anthropology\") OR (\"political anthropology\"))))) or (\"cultural anthropology\"))".
• Removing quotes may allow a broader search: (((((( visual anthropology ) or ( medical anthropology ))) or ((( criminal anthropology ) OR ( political anthropology ))))) or ( cultural anthropology )).
• Adding a wildcard symbol may retrieve word variants: (((((("visual anthropology") or ("medical anthropology"))) or ((("criminal anthropology") OR ("political anthropology"))))) or ("cultural anthropology"))*.
