That's not the assumption, Leslie.  Women might actually be BETTER at "the jobs" than some men. No, here are the assumptions: 
1. Universities treat women unfairly, with respect to certain (hard) faculties.  
2. Women are just clamoring to admission into these faculties and are being shut out because of their gender. 
3. Women need to be encouraged (in any number of ways) by others to enter these areas.  

The first two are entirely false.  The third is party true, but I'd quickly add, maybe--just maybe--women don't WANT to be scientists (or engineers, or lawyers.)  Just as some men don't want to be.  

So...we have to MAKE them want it?
