I know and some of the difference was attributable to that but not all and so they want to discuss the remaining part.
Metaphor said:...so they compared within disciplines (e.g. within social sciences, within medicine). They excluded some disciplines (such as visual and performing arts) where peer-reviewed article publication is not the main basis for promotion to professorship nor the main activity of professors.
But if you imagine there is some cutoff, women and men make the cutoff, but men have a higher average.
Here's a hypothetical example:
Woman1 - 5 publications
Woman2 - 12 publications
Woman3 - 11 publications
Man1 - 11 publications
Man2 - 5 publications
Man3 - 17 publications
Man4 - 12 publications
Man5 - 20 publications
Man6 - 11 publications
No: if the cutoff were the same, men would be promoted earlier in their careers, at the time they reached the cutoff.
The authors specifically chose to examine publication record at the time of promotion.
No that's an assumption. People apply to professorships when they are ready to do so, whatever that may mean.
The authors did not find a difference in either AGE or number of children. So, this means roughly the same age.
Over a window of time where publications are typically done prior to professorship, let's say 10 years just to get something concrete, the couples may have children, and most of the time the child-rearing is more on the woman. So, over the 10 years, she has less publications than he does, until they are the same age, let's say 34 or whatever.
So at the time of professorship, she has less and he has more on average.
Let's just look at numbers so we can see how this could impact something. Supposing a couple has 10 years where they are having children....and in and out of taking time off to raise them prior to getting children into school. Suppose the couple has 3 children. Sweden gives 480 days off parental leave per child to be divided up, but 30 percent of men take it, meaning I suppose 70 percent or thereabouts women take it...discounting same-sex couples since this is just an estimate and same-sex couples are a smaller proportion of all couples.
In 10 years of serious academic work, 3 blocks of 480 days is significant. Raising the child is even more time, but consider only the legislated time off so we just have a minimal concrete number to look at.
Woman: starting 3650 days - 70%*3*480 = 2642 days for academia
Man: starting 3650 days - 30%*3*480 = 3218 days for academia
Obviously, these are not intended to be real numbers but just to illustrate orders of magnitude and how such differences are significant to outcomes. I mean, child-rearing doesn't end at school and 480 days off of work is not the same as how long it takes to raise a kid. 10 years in academia prior to a professorship is also just an arbitrary number of the appropriate order of magnitude--it's not 1 year and it's not 100.
You're doing a fine job of proving his point--they are discriminating in favor of women in order to "balance" things.
