narrative technique of "Transworld identity" in child and adolescent stories, with an ontological approach

Brian McHale, with a philosophical look, looked at the text as the world, and called the relationship of the worlds as transworld. McHale borrowed the term “Transworld identity” from Umberto Eco, and used it in the sense of “the transmigration of characters from one fictional universe to another". The McHale's purpose of raising such a paradigm was to explain the dominant ontological element in postmodern stories. Since it is common the ontological infrastructure of science fiction and imaginative stories with the infrastructure of postmodern stories, and on the other hand, the use of the "Transworld identity" as a knitting or relieving method, in addition to postmodern stories, has a high frequency in the child's fantasy stories and adolescent science fiction, the present study, using a descriptive analytical method, and with the aim of case study examining of this widely used storytelling style, is looking for the answer of three fundamental questions: how many types of ontological structural relationships do the worlds may have together, which are used as a platform for Transworld identity? What are the most popular themes for classifying the Transworld identity in child and adolescent stories? What is the relationship between the ontological mixing of the above mentioned universes and their complexity, with regard to the child's audience? In the context of Iranian fictional literature and in particular, the story of the children and adolescents, the present study, for the first time, deals with the Transworld identity and the relationship between its underlying worlds.
