I am doing an assignment about how the Quran affects the view points of Muslims on the roles of men and women and it would really help me, if someone could answer some questions

What are the fundamental and liberal views on the roles of men and women?
What are the Sunni and Shi'a (Shiite) views on men and women?
How does or can a non Islamic society change or alter a Muslim's viewpoint on men and women. Why?

Thanks
