Landscape Fragmentation Driven by Land Use Change Dominates the Spatiotemporal Heterogeneity of Non‐Point Source Pollution Loads in Human‐Intensive Basins: A Case Study of the Dongjiang River Basin, China

open access: yesLand Degradation &Development, Volume 37, Issue 14, Page 10440-10463, 30 August 2026.
ABSTRACT Landscape fragmentation may influence the spatial distribution and temporal variation of non‐point source (NPS) pollution by altering hydrological processes, pollutant transport pathways, and ecosystem service functions. However, under the combined effects of natural factors (e.g., precipitation, topography) and anthropogenic factors (e.g ...

Does digital surveillance boost citizen compliance? Evidence from China

open access: yesPolitical Psychology, Volume 47, Issue 4, August 2026.
Abstract Authoritarian regimes increasingly deploy digital surveillance to monitor citizens, but how this affects citizen compliance remains understudied. We argue that, beyond repressing or deterring regime opponents, digital surveillance serves as an instrument of everyday governance that operates through psychological mechanisms rather than direct ...

Monte Carlo Simulation of 3D Cloud Radiance Distributions Affected by Ground‐Based Lighting

open access: yesJournal of Geophysical Research: Atmospheres, Volume 131, Issue 6, 28 March 2026.
Abstract Satellite observations of artificial light sources at night are increasing. Clouds, as the most important radiative modulators in the Earth‐atmosphere system, significantly influence the observed values and spatial distribution of the artificial light coming from the ground.
