Latin American Policy, Volume 16, Issue 4, December 2025.ABSTRACT In recent years, video assistant referee systems have been increasingly used to correct unfair decisions in sports. Similarly, I argue that constitutional referendums play a corrective role in hybrid or competitive authoritarian regimes, where the electoral referee is biased and the government enjoys unfair advantages.

The Political Empowerment of Women and Industrialization in Africa
Politics &Policy, Volume 53, Issue 6, December 2025.ABSTRACT This study examines the effect of political empowerment of women on industrialization in Africa. The results, after controlling for cross‐sectional dependence, show that women's political implication causes industrialization. The fixed effects Driscoll/Kraay standard error and the GMM estimators reveal that women's political empowerment ...

全球能源互联网, 2018 针对光伏逆变器并网电流谐波较大的问题，首先对三电平逆变器的主电路结构进行了分析，得出了网侧输出电流的数学模型，并分析了该模型下逆变器谐波产生的机理。在分析了传统的PI+重复控制的基础上，针对传统PI与重复控制相互耦合容易导致等效重复控制对象不稳定的问题，提出了一种双PI+重复控制（double proportional integral + repetitive control，DPI+RC）的控制策略。采用PI补偿，在保证了传统PI+重复控制系统跟踪的快速性和准确性前提下，确保了系统的稳定性。最后 ...

Improvements for better scaling of locally managed marine areas
Conservation Biology, Volume 39, Issue 5, October 2025.Abstract To protect and restore ecosystems at the speed and scale required to meet current environmental challenges, a greater understanding of how conservation initiatives spread from existing to new adopters is required. According to the diffusion of innovation theory, positive adopter‐to‐peer communication is a powerful driver of innovation spread ...

Influences on cannabis policy design and adaptation in the American states
Policy Studies Journal, Volume 53, Issue 3, Page 723-746, August 2025.Abstract Despite federal prohibitions, three‐quarters of states had implemented medical marijuana laws (MML) and one‐third had implemented recreational cannabis laws (RCL) by 2020. State policy designs varied considerably, and we focus on policy development and maturation in policy implementation, examining factors influencing design features of policy
