Bulletin of Chinese Academy of Sciences (Chinese Version)
Critical infrastructures are vital strategic resources, directly impacting national security and the operation of economy and society. Twenty-two megacities and large cities in China, due to the concentration of resources and poorly concealed distribution of critical infrastructure, face multiple risks such as warfare attack, natural disaster, and facilitiy aging. Incorporating the undergroundization of critical infrastructure into national strategy is an imperative choice for national security, resilient city, and high-quality growth. International practices have proven the advantages of underground development in terms of protection and space optimization. During the 15th Five-Year Plan period, it is recommended to adopt strategies such as …

Unpacking Shared Pessimism Between Citizen And Bureaucracy: A Socio-Psychological Barrier To Public Service Reform In Indonesia, Reza Fathurrahman, Christoph Hoennige
Unpacking Shared Pessimism Between Citizen And Bureaucracy: A Socio-Psychological Barrier To Public Service Reform In Indonesia, Reza Fathurrahman, Christoph Hoennige
BISNIS & BIROKRASI: Jurnal Ilmu Administrasi dan Organisasi
In this study, we examine the existence of a reciprocal pattern of performance bias shared between citizens and street-level bureaucrats, which we term as ‘shared pessimism’, assumed to implicate public service reform. Primary data were collected using surveys administered to 207 public service providers and 248 citizen recipients across six Indonesian public service agencies operated in two regional governments. Statistical analysis was then conducted to examine bureaucrats’ self-enhancing bias and their pessimistic view of citizen ratings, as well as to clarify citizens’ tendency to underrate the performance of bureaucrats in public service organizations. Our findings confirm pervasive internal pessimism amongst …

Frontiers In Ocean Non-Equilibrium Dynamics And Challenges In Operational Oceanography Application, Yuhong Zhang, Yan Du, Tianyu Wang, Minyang Wang, Qin Duan, Xinlong Li, Yuhang Zheng, Yifan Xia, Shilin Tang, Yineng Li, Jianping Yin
Bulletin of Chinese Academy of Sciences (Chinese Version)
Ocean circulation exhibits complex multiscale dynamics, among which non-equilibrium processes, marked by transient behavior, strong perturbations, and pronounced nonlinearity, are of particular importance for maritime environmental support. However, limited observational capability has long constrained the study of subsurface non-equilibrium dynamics, leaving numerical models insufficiently validated and positioning this issue at the forefront of modern physical oceanography. Artificial intelligence (AI) offers a promising pathway to overcome this bottleneck. Built on this concept, the “iEddy” AI large ocean model can efficiently reconstruct high-resolution, high-accuracy three-dimensional temperature, salinity, and velocity from sea-surface remote sensing data, demonstrating strong capability in capturing non-equilibrium ocean currents …
