  1. Three-dimensional psychological control scale was invariant across informants and time
    Study validates a Chinese measure of parental psychological control with three dimensions, establishing its consistency across parent and adolescent informants and over 6-month interval.
  2. Ze counting framework yields a Minkowski-like metric
    A derivation of Minkowski spacetime geometry from combinatorial dynamics of a binary event counter, with speed of light emerging as structural impedance.
