Full text linkAs a well-known founder of the Nankai School in the Republican period of China, Chang Po-ling started an example to develop private education and persuade people to donate money on education. During this process, due to his “Nankai spirit”of diligence and striving, Mr. Chang Po-ling who was full of strong patriotic sentiment from beginning to end, affected a lot of domestic military and political figures, entrepreneurs and business owners, schoolfellows, directors, international friends, founds and organizations, and attracted them to support and focus on education initiators. Through various ways and a series of practical activities, Chang Po-ling persistently encouraged everyone to donate money on education and gained the continuous development of Nankai School. When looking back at Chang Po-ling’s process of persuading people to donate money on education, we can not only see his extremely excellent and brilliant achievements on school running, but also can study and reflect on how to utilize social force to service for current education

Satellite radar interferometry (InSAR) techniques have been successfully applied for structural health monitoring of line-infrastructure such as railway. Limited by meter-level spatial resolution of Sentinel-1 satellite radar (SAR) imagery and meter-level geolocation precision, it is still challenging to (1) categorize radar scatterers (e.g., persistent scatterers (PS)) and associate radar scatterers with actual objects along railways, and (2) identify unstable railway segments using InSAR Line of Sight (LOS) deformation time series from a single viewing geometry. In response to this, (1) we assess and improve the 3-D geolocation quality of Sentinel-1 derived PS using a 2-step method for PS 3-D geolocation improvement aided by laser scanning data; after geolocation improvement, we step-wisely classify railway infrastructure into rails, embankments and surroundings; (2) we recognize unstable rail segments by utilizing the (localized) differential settlement of rails in the normal direction (near vertical) which is yielded from the LOS deformation decomposition. We tested and evaluated the methods using 170 Sentinel-1a/b ascending data acquired between January 2017 and December 2019, over the Betuwe freight train track, in the Netherlands. The results show that 98% PS were associated with real objects with a significance level of 25%, the PS settlement measurements were generally in line with the in-situ track survey Rail Infrastructure aLignment Acquisition (RILA) measurements, and the standard deviations of the PS settlement measurements varied slightly with an average value of 6.16 m
