"The first multi-disciplinary study to examine the status of doctoral students in the social sciences at least five years after receiving their degree concludes that doctoral programs need to be brought into the 21st century."
For example, they found that "The average graduate student is not an 'unencumbered young man.' Schools need to confront the work-family tension that exists in doctoral careers, both for men and women, more than half of whom are married and in their early to mid 30's by the time they receive their PhD. Women reported making more compromises in juggling work and family than men."
