[Polarization] Wang, S., Wang, T., Yokoyama, H.M. et al. Beyond a single pole: exploring the nuanced coexistence of scientific elitism and populism in China. Humanit Soc Sci Commun 12, 353 (2025). https://doi.org/10.1057/s41599-025-04685-3

While there is active discussion about polarization in the West, in China we have confirmed the phenomenon of elitism and populism coexisting within one person./欧米では２極化の議論がさかんですが、中国では１人の中にエリートリズムとポピュリズムが共存する現象が確認されました。

What is interesting is that through crowdfunding research, the paper proposes a "Budget-funding Community" in contrast to the Journal Community, which is important in scientific theory.We propose that science crowdfunding can be successfully used to generate “crowd-supported science” by means of this Crowd Community./クラウドファンディング研究を通じて、科学論で重視する Journal Communityに対して、”Budget-funding Community”を提案したところに面白さがあります。さらに、科学クラウドファンディングをうまく活用した「クラウド支援型科学」があることを明らかにしました。
