When referring to what authors have written in the literature you should use past tense. Thompson stated, not states. When referring to your dissertation study when you are completed, you will refer to what you did in the past tense. For the proposal use future tense--The purpose of the proposed study will be to… not is (is in the present tense). When you indicate what is in a chapter of your proposal or dissertation, use present tense because what you have written will always be in the chapter, thus in the present.
