This seminar explores how economic development, migration, and gender shape family relationship. The number of families living apart while together transnationally has risen rapidly in Taiwan since the late 1980s due to the large movement of Taiwanese people to China and somewhere else for business and work. Married Taiwanese women and men who are partially free from and yet partially constrained by the daily tasks and responsibilities related to their spouses and families as well as the social and moral constraints imposed by their marital status by living apart for an extended period of time. The intimate relationships between Taiwanese people and their family have been in a state of interspersion and interpenetration across spatial and temporal contexts. What I have found is that over the course of their long-term separation, there are disjunctures and independencies but also reinforced co-dependency between them materially, emotionally, and morally due to the gendered practices of situational singlehood. It is simultaneously the reinforcement of some established norms and the deinstitutionalization of others that keep transnational Taiwanese businessmen’s marriages and families together. In this seminar, I discuss the concept of “intimacy jet lag” to theorize this disjunctive yet co-dependent nexus of relations among those families.
