Final answer:
It is unclear which specific study is being referenced concerning the commitment of university students from dual-career families to role-sharing marriages. However, an increased number of dual-income households and evolving marriage dynamics signify changing gender roles and expectations in marriages.
Step-by-step explanation:
The question pertains to the results of a study on university students who were raised in dual-career families and their inclinations towards a role-sharing marriage. While the question does not specify the author of the study, we see a significant trend indicating that young men and women from dual-income households are more likely to be committed to an egalitarian, role-sharing marriage. Increased presence of married women in the labor force, as reported by the Bureau of Labor Statistics, and a shift in marital dynamics where high earners marry other high earners suggest changing expectations and roles within marriages over recent years.
In the context of provided resources, authors such as Hawke (2008) and Popenoe and Whitehead (2004) have explored dynamics in American marriage and views on marital satisfaction. These studies contribute to understanding how perceptions of marriage and family life evolve over time, especially considering the increased participation of women in the labor force and the emergence of role-sharing marriages.
