WHYme, I am not suggesting your daughter do this but thought I would relate a little story to you.

Wifey had a similar problem with a female colleague years ago at a job she had recently been hired at. After about three months of the same harassment, carry go bring come, throw word and bad mine, she walked into her office at the end of the day, on a Friday, closed the door and locked it behind her.

She sat down and said to the women, "you and I need to have a little talk as their appears to be some misunderstanding and I am here to make sure you understand who you are dealing with". She then proceeded to tell this woman bascially, that if she did not stop f'ing with her, she was going to kick her ass. No name calling or shouting. She was very professional and low keyed but used body language, tone of voice and that "look" that only JA women have to let her know that she was dead serious.

Never had a problem after that.
