Body proportions in three Nigerian tribes

Prediction equations of body composition based on measurements of whole-body bioelectrical impedance analysis (BIA) have been found to be population-specific. It was hypothesised that this may be, in part, due to differences in proportional limb lengths between ethnic or racial groups. As a preliminary to a survey of body composition in urban Nigerians using BIA, the relative limb lengths of the three major tribal groups (Hausa, Yoruba and Ibo) were determined. We found small (5-9%) but significantly longer limb lengths in Nigerians compared to a Caucasian population, but no significant differences between tribes. This implies that BIA prediction equations generated in a Caucasian population are inappropriate for use in a Nigerian population.

Black and white and re(a)d all over again: Indigenous minstrelsy in contemporary Canadian and Australian theatre

This essay considers processes by which community identities are challenged by discussing the use of whiteface as an activist strategy in recent indigenous theatre in Canada and Australia. To understand whiteface, I employ Susan Gubar's notion of racechange, processes that test and even transgress racial borders. I also situate whiteface in relation to the history of blackface minstrelsy. Noting the ways these racial performances affirm the hierarchies of color and how power becomes invested in such color codings, the essay highlights indigenous employment of whiteface as a potential form of critical historiography. I then analyze how whiteface functions in two productions, Daniel David Moses's Almighty Voice and His Wife (1991) in Canada and the Queensland Theatre Company's 2000 revival of George Landen Dann's Fountains Beyond in Australia. My analysis posits that such indigenous performances of whiteface can affirm the identity of the marginalized other even as they destabilize the fixity of race and its meanings.
