Ok, here is a brainstorming exercise for today. In Google Scholar, put in a random subject that does not apply to your work, or only tangentially so. Then, just based on the sound or word choices of a few titles, try to write a couple of titles on your area of interest. Mimic the style and tone, if you will, of the titles you found. This is a brainstorming exercise, designed to stimulate creativity, so do not judge what you are writing while you are writing.
Repeat this a couple of times, and see if you have not come up with a new article idea.
