NPR recently had a great report[1] on women in the sciences they said "When women were reminded — even subtly — of the stereotype that men were better than women at math, the performance of women in math tests measurably declined" so one might think that this living expense would reinforce that stereotype, however they concluded that "In order to boost the numbers of women who choose to go into those fields, you have to boost the number of women who are in those fields." Which is exactly what this stipend will do and hopefully that positive will out way any perceived negative. I think its a great experiment and you might want to reach out to the researchers in this report to see if they would be interested in what you're doing.
