The effect of sibling size on high school and vocational streaming
In China, an increase in siblings (SNincrease) reduces children’s senior high school entrance examination (SHSEE) scores and their likelihood of admission to senior high school (HSchance). • The negative effects of SNincrease on SHSEE and HSchance are stronger for higher-ESCS families and for children in Beijing and Shanghai. • Compared with other regions, the resource dilution from an additional child is more pronounced in higher-ESCS families a…
Exercise identity and physical activity according to socioeconomic status in China
Objective and subjective SES differentially affect exercise identity and physical activity. Moreover, gendered expectations appear to modify the pathway from objective SES to physical activity via exercise identity, suggesting that interventions to promote exercise might benefit from consideration of both socioeconomic and identity-related factors
Variability in ice shelf basal melting in the Amundsen Sea Embayment from 2019 to 2023
The Amundsen Sea Embayment (ASE) of West Antarctica is one of the most crucial regions for understanding current ice-sheet mass loss and its impact on global sea-level rise. Past observations have revealed rapid thinning of ice shelves, driven primarily by ocean-induced basal melting of their undersides. These processes weaken the shelves’ buttressing effect, potentially accelerating inland ice discharge, and raising concerns about marine ice-she…
