“…The terms "sex" and "gender" are no longer considered to be interchangeable (Lerner, 1986;Nicholson, 1994;Rubin, 1975;Seifert, 1991). Cross-cultural research, for example, has convincingly demonstrated the expansiveness of the concept of gender through fieldwork in societies that do not adhere to a male-female dichotomy but, rather, include a third or even a fourth gender category (e.g., Blackwood, 1984;CaUender and Kochems, 1983;Herdt, 1994;Hollimon, 1997;Meigs, 1990).
