Too many years ago I was a participant in a series of workshops sponsored by the AI community on "composite systems" an area concered with the design of large scale systems that integrated automated and human components - one of the concerns in ULS.
Way too many years ago my dissertation sought to find a means to integrate culture - as anthropogists understand the term - into models of cognition, another area that I believe relevant to ULS.
