media - Questions on journalism and women

(picture by Dan Gillmor, last monday)
Together with Dan Gillmor I wondered on Monday why the class of the journalism school at Fudan University was 100 percent female. Most journalism schools have a majority of women, but even the official Fudan-figure, ninety percent women, is way out of line with the averages elsewhere.
One theory I heard today from a quasi-insider is that already at the gate of the journalism school the men are stopped. Women mainly focus on harmless subjects like fashion and the trendy stuff, men are more ambitious and would perhaps sooner go for more political subjects. Women are easier to handle and to manipulate, my (male) source said.
That would not explain why women complain that men are preferred by media organizations when jobs are handed out. (See the comments in Dan's entry).
Any more ideas here?
