"But some who have observed or trained once-recalcitrant men cite small successes in changing perceptions about the nature of 'male' jobs."

"Ellen Bravo, a director of Family Values at Work, found that male firefighters in Kansas City, Mo., had adapted to changes they once dismissed as unmanly, such as wearing masks to protect against lung cancer or talking about grief after witnessing death and suffering. Jessica Smith, an associate professor at the Colorado School of Mines, studied the successful experience of women in a Wyoming mine in the 2000s during a time of hiring expansion, when women were not perceived as taking jobs from men. 'They redefined what it was to be a good miner away from this very hyperbolic masculine image,' she said. 'A good miner was someone who cared for their co-workers. They were responsible. These were issues that women could also embody.'"
