Risk, Hazards &Crisis in Public Policy, Volume 14, Issue 4, Page 343-365, December 2023., 2023 Abstract This article traces the historical evolution of risk perception around the Nuclear Research Centre Karlsruhe, Germany, from 1956 to 1997. It does so by targeting the evolution of water‐related risks. Federal hopes in the postwar era that the Nuclear Research Centre would bring progress and prosperity clashed with local values and local ...

Review of European, Comparative &International Environmental Law, Volume 32, Issue 1, Page 105-118, April 2023., 2023 Abstract This article compares the framework of environmental public interest litigation in China to the individualized system of judicial review in Germany. It shows that environmental reform requires modern States such as Germany and China to consider certain objective criteria related to the public interest.

Strangers on the ladder of the party‐state: Women in teaching in Nationalist Taiwan, 1940s–1980s
Gender &History, Volume 38, Issue 1, Page 273-288, March 2026.Abstract As the ruling party of a party‐state in China and Taiwan, the Nationalist Party (Kuomintang/Guomindang) built a close relationship with the teaching profession. Many teachers joined the party and there was a well‐trodden pathway from teaching into local representative politics and civil service.
