Re-Examining the Frustrated Homemaker Hypothesis

Multiple Classification Analyses on responses from 946 white women, drawn from the 1972 American National Election Study survey, were used to test the "frustrated homemaker hypothesis" that full-time homemakers are more dissatisfied with their lives than women employed outside the home. The fit between actual and desired roles proved to be a better predictor of personal satisfaction than the traditional dichotomy between homemakers and employed women. Homemakers who had wanted a career were more personally dissatisfied than homemakers who had never wanted a career. The career-oriented homemakers were the ones who expressed greater personal dissatisfaction than employed women. Employed women and career-oriented homemakers were about equally critical of women's collective position in society, while homemakers who had never wanted a career were more accepting of women's status quo. The importance of including evaluations of both personal and collective well-being was shown by the fact that these two domains bore different relationships to employment-homemaker status.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/69078/2/10.1177_073088848100800404.pd

Heterochromatin: A Rapidly Evolving Species Barrier

Recent work has shown that changes in the sequence composition of heterochromatin, or in the factors that maintain that heterochromatin, may play an important role in speciation

Intra-Household Work Timing: The Effect on Joint Activities and the Demand for Child Care

This study examines whether couples time their work hours and how this work timing influences child care demand and the time that spouses jointly spend on leisure, household chores, and child care. By using an innovative matching strategy, this study identifies the timing of work hours that cannot be explained by factors other than the partners' potential to communicate about the timing of their work. The main findings are that couples with children create less overlap in their work times and this effect is more pronounced the younger the children. We find evidence for a togetherness preference of spouses, but only for childless couples. Work timing also influences the joint time that is spent on household chores, but the effect is small. Finally, work timing behaviour affects the demand for informal child care, but not the demand for formal child care

Life and Death of an Influential Passenger: Wolbachia and the Evolution of CI-Modifiers by Their Hosts

Wolbachia are intracellular bacteria widely distributed among arthropods and nematodes. In many insect species these bacteria induce a cytoplasmic incompatibility (CI) between sperm of infected males and eggs of uninfected females. From an evolutionary point of view, CI is puzzling: In order to induce this modification-rescue system, Wolbachia affect sperm of infected males even though Wolbachia are only transmitted maternally. Phylogenetic studies of Wolbachia and hosts show that the bacteria rarely cospeciate with their hosts, indicating that infections are lost in host species. However, the mechanisms leading to Wolbachia loss are not well understood.Using a population genetic model, we investigate the spread of host mutants that enhance or repress Wolbachia action by affecting either bacterial transmission or the level of CI. We show that host mutants that decrease CI-levels in males (e.g. by reducing Wolbachia-density during spermatogenesis) spread, even at cost to mutant males. Increase of these mutants can lead to loss of Wolbachia infections, either as a direct consequence of their increase or in a step-wise manner, and we derive analytically a threshold penetrance above which a mutation's spread leads to extinction of Wolbachia. Selection on host modifiers is sexually antagonistic in that, conversely, host mutants that enhance Wolbachia in females are favoured whereas suppressors are not.Our results indicate that Wolbachia is likely to be lost from host populations on long evolutionary time scales due to reduction of CI levels in males. This can occur either by evolution of single host modifiers with large effects or through accumulation of several modifier alleles with small effects on Wolbachia action, even at cost to mutant males and even if infected hosts do not incur fecundity costs. This possibility is consistent with recent findings and may help to explain the apparent short evolutionary persistence times of Wolbachia in many host systems
