Gender‐focused college courses seek to increase understanding of the systematic advantages associated with dominant group membership. These courses attempt to reduce prejudice and raise awareness of male and heterosexual privilege. Inclusion of privilege content within gender‐focused courses has increased, but research to test interventions to increase privilege awareness and reduce prejudice remains sparse. The current studies provide experimental information about awareness of heterosexual privilege (Study 1) and male privilege (Study 2) and specific interventions for use in education, professional development, and community settings. Study 1 found the video intervention was effective in increasing heterosexual privilege awareness and internal motivation to respond without prejudice. Study 2 found that male privilege awareness was significantly increased and modern sexism was reduced by the video intervention. Findings provide information for applied practices such as pedagogical strategies when designing diversity courses and training workshops.

To assess the effects of adsorption on protein structure, ultraviolet optical absorption spectra of myoglobin (Mb) bound to polydimethylsiloxane (PDMS) were measured. A flow cell, which enabled adsorption under controlled hydrodynamic conditions, was used in conjunction with a conventional spectrophotometer to obtain the spectra. Adsorption to PDMS reduced significantly the absorbance in the Soret region of the Mb spectrum, whereas the spectrum in the region near 280 nm was essentially unaffected. This result showed that disruption of the native structure of Mb occurs following interaction with PDMS. Furthermore, the change in the absorption spectrum may indicate loss of heme from the heme pocket of the adsorbed protein. Mb structure was altered from its solution configuration within fifteen min of contact with the surface. Exchange of adsorbed Mb with Mb in solution had little or no effect on the absorption spectrum of the surface-confined protein, indicating that exchange occurs only between conformationally altered species or between native species.
