“Doing” Gender in Context: Household Bargaining and Risk of Divorce in Germany and the United States

Gender relations remain embedded in their sociopolitical context. Compared here using event-history analysis is how household divisions of paid and unpaid labor affect marital stability in the former West Germany, where policy reinforced male breadwinner families, and the United States, where policy remains silent regarding the private sphere. In Germany, any moves away from separate gendered spheres in terms of either wives' relative earnings or husbands' relative participation in housework increase the risk of divorce. In the United States, however, the more stable couples are those that adapt by displaying greater gender equity. These results highlight that policy shapes how gender gets done in the intimate sphere, and that reinforcement of a gendered division of labor may be detrimental to marital stability.

Verbal and physical aggression in couples where the female partner is drinking heavily

This study evaluated (i) frequencies of aggression in maritally distressed problem drinking (DP) women relative to controls, (ii) aggression, marital satisfaction, and partner drinking in predicting female drinking, and (iii) discrepant within-couple drinking in predicting marital distress. The sample included 27 DP women, 24 maritally distressed nonproblem drinking women (DNP women), and 24 women with neither problem (NDNP women). DP women reported frequencies of physical aggression similar to DNP women, but less male verbal aggression than DNP women. Predictors of female drinking were marital satisfaction and male drinking, but aggression did not predict female drinking. Female marital satisfaction was predicted by interspousal discrepancies in drinking after accounting for verbal aggression.

Victim-perpetrator differences in reports of hurtful events

This research project addressed limitations identified in previous studies of role differences (victim vs. perpetrator) in evaluations of hurtful events. The study employed multiple methods (open-ended and structured retrospective reports and experience-sampling diary records), and involved a community sample of both dating and married couples. Retrospective reports indicated that the extent and direction of role-related differences varied markedly across dependent measures. Further, role differences were moderated by forgiveness, but not relationship status, relationship satisfaction, or event severity. Diary records pointed to the ambiguity inherent in many communication acts as contributing to differing perceptions of hurtful events. Results are discussed in terms of theories of interdependence and self-presentation and in terms of the complex and often ambiguous nature of couples' communication processes.

Motion analysis of right ventricular wall based on an electromechanical biventricular model

Based on our previously developed electrical heart model, an electromechanical biventricular model, which couples the electrical property and mechanical property of the heart, was constructed and the right ventricular wall motion and deformation was simulated using this model. The model was developed on the basis of composite material theory and finite element method. The excitation propagation was simulated by electrical heart model, and the resultant active forces were used to study the ventricular wall motion during systole. The simulation results show that: (1) The right ventricular free wall moves towards the septum, and at the same time, the base and middle of free wall move towards the apex, which reduce the volume of right ventricle; (2) The minimum principle strain (E3) is largest at the apex, then at the middle of free wall, and its direction is in the approximate direction of epicardial muscle fibers. These results are in good accordance with solutions obtained from MR tagging images. It suggests that such electromechanical biventricular model can be used to assess the mechanical function of two ventricles.
