There was an interesting quote from the show Mr Roboto that went something like, "Everything is about sex, except sex, which is about power."
That seems to correlate pretty well with what this study says.
What I find interesting about the whole sexual harassment, sexual assault furor that's erupted in Murica recently is the fact that nobody seems to be aware of the fact that it's not about sex, it's about power.
I can speak from the viewpoint of decades in the workplace and say that the people who abuse their power don't just do it to members of the opposite sex and it's not always sexual in nature.
Making you work late at the last minute or having you come in on the weekend or any number of bullshit tasks assigned to "underlings" is just a different manifestation of the same kind of behavior.
