My female JRT Bites me

(Mesa, AZ)

I acquired a 4 year old non-spayed female JRT from a young couple who just had a baby. She is very sweet and loving most of the time, and she is great with my male, same age. I have only 2 problems that I seem to be unable to handle. When she sees someone, or another animal (cat or dog), walking in front of our house, she barks non-stop and I am unable to get her attention to stop her barking. I have tried touching her to get her attention, but she turns her aggression on me and tries to bite me. She even jumps up to try to bite. I have also tried grabbing her around her neck, just behind her head, but she still manages to get her head turned enough to bite my fingers. If I am able to get her calmed down, she becomes the sweet loving JRT. Can you give me any advice on how to correct these two problems.
