Some other cultures do not recognize a homosexual/heterosexual/bisexual distinction. It is common to distinguish a person's sexuality according to their sexual role (active/passive; insertive/penetrated). In this distinction, the passive role is typically associated with femininity and/or inferiority, while the active role is typically associated with masculinity and/or superiority. For example, an investigation of a small Brazilian fishing village revealed three sexual categories for men: men who have sex only with men (consistently in a passive role), men who have sex only with women, and men who have sex with women and men (consistently in an active role). While men who consistently occupied the passive role were recognized as a distinct group by locals, men who have sex with only women, and men who have sex with women and men, were not differentiated. Little is known about same-sex attracted females, or sexual behavior between females in these cultures.
How much is known about lesbians and bisexual women in these cultures?
Little

Despite these detailed standard definitions, cameras typically do not clearly indicate whether the user "ISO" setting refers to the noise-based speed, saturation-based speed, or the specified output sensitivity, or even some made-up number for marketing purposes. Because the 1998 version of ISO 12232 did not permit measurement of camera output that had lossy compression, it was not possible to correctly apply any of those measurements to cameras that did not produce sRGB files in an uncompressed format such as TIFF. Following the publication of CIPA DC-004 in 2006, Japanese manufacturers of digital still cameras are required to specify whether a sensitivity rating is REI or SOS.[citation needed]
In what year was CIPA DC-004 introduced?
2006

According to Tibetologist John Powers, Tibetan sources counter this narrative of titles granted by the Chinese to Tibetans with various titles which the Tibetans gave to the Chinese emperors and their officials. Tribute missions from Tibetan monasteries to the Chinese court brought back not only titles, but large, commercially valuable gifts which could subsequently be sold. The Ming emperors sent invitations to ruling lamas, but the lamas sent subordinates rather than coming themselves, and no Tibetan ruler ever explicitly accepted the role of being a vassal of the Ming.
Who did the Ming emperors send invitations to?
ruling lamas
