Explain your use of "discrimination", regarding the field of computer science.
Don't you see? Read carefully this passage:
"Today, Souvaine chairs the Tufts University computer science department, which has more female professors than male. But few younger women have followed in her generation's footsteps. Next spring, when 22 computer science graduates accept their Tufts diplomas, only four will be women."
So although a small minority of graduates are women they get majority of faculty positions. If this is not a discrimination, what is?
