Unpack the black box of pilot sampling in policy experimentation: A qualitative comparative analysis of China's public hospital reform

Governance, Volume 37, Issue 3, Page 803-824, July 2024.
Abstract Governments increasingly use policy experimentation programs to seek solutions for complex problems. Because randomization and controllability are unrealistic for real‐world policy experiments, how subnational pilots are selected is crucial for generating sound evidence for national replication.

Analysis and comparison of direct inversion and Kalman filter methods for self -powered neutron detector compensation

, 2020
Many light-water reactors use self-powered neutron detectors (SPNDs) to monitor neutron flux. Some SPNDssuffer from delayed response. To compensate for this inherent delay, many methods such as the direct inversionmethod (DIM) and the Kalman filter ...
