My new research shows that overworking single-breadwinner families have become more economically competitive with non-overworking dual-breadwinner families—especially at the top of the income distribution. doi.org/10.1093/sf/s...

Fascinating study of video data on class differences in parenting styles about food and mealtimes. Class differences in parenting styles are fairly weak and the boundaries blurry. #socsky: a good addition to syllabus if you teach Lareau or Bourdieu, or more generally about social class "cultures."

Interesting new paper on "overwork" (long work hours per week) in China. Shows that, contra the US, overwork is concentrated in blue-collar occupations rather than in the professions, and is associated with a wage penalty -- lower pay per hour of work -- rather than a wage premium.

The Changing Educational Gradient in Nontraditional Attitudes toward Family Behavior: A Cross-National Study
The second demographic transition (SDT) theory highlights how nontraditional family behaviors first emerged in Nordic countries and diffused elsewhere.

I think this is great news. It could lead to a new stream of stratification research comparing Japan with European countries, which hasn’t fully revived after the CASMIN project of the 1980s / early 1990s. Japan’s educational system is, for one, particularly interesting.
Europe always chooses science and partnership. Japan too. Japan is now officially associated with Horizon Europe. This means Japanese researchers and organisations can take part in the world's largest public research and innovation programme. Let's break new frontiers together.
