Could you please clarify what you mean by "Jocano theory"? Perhaps you're thinking of:
* A specific author or researcher: If you can remember the name of the person who created this theory, it will be much easier to identify it.
* A specific field of study: Are you thinking of a theory related to sociology, psychology, anthropology, economics, or another discipline?
* A specific topic: What is the theory about? Is it about human behavior, cultural development, social dynamics, or something else?
Once you can provide more information, I can help you find the theory you're looking for.
