Population shrinkage and cropland fragmentation in Northeastern China
Rural population decline and rapid ageing are reshaping agricultural regions, yet their implications for the reorganisation of agricultural land systems remain insufficiently understood. Focusing on Northeastern China, a major grain-producing region experiencing sustained out-migration and rural labour loss, we examine the relationship between population shrinkage and cropland fragmentation. Using demographic data and annual 30 m land-cover data …
Does body composition mediate the association between moderate-to-vigorous physical activity and physical literacy in school-aged children? A cross-sectional mediation analysis
Background Childhood obesity and physical inactivity are growing global public health concerns. Once predominantly observed in wealthier nations, these issues are now increasingly prevalent in low- and middle-income countries. We aimed to examine the relationship between moderate-to-vigorous physical activity (MVPA) and physical literacy (PL) among children aged 8–12 years, and to determine whether body mass index (BMI) mediates this association.…
Time Invariant Variables in the Mundlak and Hausman–Taylor Panel Data Models
This paper shows that the classic augmented Mundlak regression yields the between estimator for time‐invariant variables. It is well known that the estimates of the time varying variables yield the fixed effects estimates. While the latter are consistent for this correlated random effects model, the between estimates are not. The between estimator is consistent only when the Hausman test does not reject the null based on between versus fixed effe…
