We recently had a "Women in my Department" dinner, organized by the university's chapter of "Association for Women in my Field". Attendance was low, and towards the end, discussion turned to how to get more undergrads to attend.
A visiting graduate student suggested that we open the meeting up to all undergraduates. After all, it was the Association for Women in my Field, not Association of Women in my Field. It turns out that in her department, the AWmF has a male faculty mentor. (This is because there are no female tenured faculty at her department).
There's a part of my brain that started screaming "BAD IDEA!" at the top of it's lungs. But then I stopped to think about it. As an undergraduate, there was 1 tenured female faculty member in my two majors combined, 2 my last year. There was a "Graduate Student Women in My Field" group that did not get money from any outside agency, and was not aimed at undergrads (though we were welcome), and thus did not need a faculty sponsor. Would it have been fair in my undergrad institution to put the responsibility/burden of running such a group on the 1 female? Is it a fair responsibility to shuffle off onto a junior faculty member? Does that change if the school has a low rate of offering tenure?
There were 2 tenured female faculty members in my graduate department, neither of whom really wanted to spend time on an "Association for Women in My Field" chapter. One department chair tried to foist it onto one of them, and created a bit of resentment in the process.
In some ways, I'm glad the male faculty member at the visiting student's school is sponsoring a chapter of Association for Women in My Field, broken as this problem is.
