China's Eco‐Civilisation, Climate Leviathan, and Hobbesian Energy Transition
Antipode, Volume 57, Issue 3, Page 830-861, May 2025.Abstract Scholars have hitherto tended to theorise China's ecological civilisation project either as a form of environmental authoritarianism or as a vision of eco‐socialism. This paper contributes to the conversation by conducting a textual analysis of Chinese scholarly discussions on eco‐civilisation.

Uncovering Xi Jinping's Policy Agenda: Text As Data Approach
The Developing Economies, Volume 63, Issue 1, Page 9-46, March 2025.How many agendas has Xi Jinping put forth and promoted since taking office in 2012, and what are the types of agendas? How much of political attention has each agenda received, and how has the allocation of attention changed over time? We utilize a dataset of presidential statements, speeches, and reports from 2012 to 2022 and employed automated text ...

The Mechanism underlying Amyloid β 1-42-induced Upregulation of APP Level [PDF]
, 2012 Aβ肽是伴随阿尔茨海默症发病过程的淀粉样沉积斑的主要成分。Aβ是由其前体蛋白APP被β-和γ-分泌酶依次水解后所产生。Aβ，特别是其聚集形式，对神经细胞具有毒性。体外孵育的Aβ向纤维状形式转变的过程会增加其结合神经元细胞膜蛋白的能力，这其中就包括了APP本身。因此APP除了直接生成Aβ以外，还可能作为细胞表面蛋白来介导Aβ毒性。 在本论文的实验中，我们研究了自发聚集的Aβ1-42对人神经母瘤细胞中Aβ前体蛋白APP的表达水平及代谢过程的影响。我们发现，Aβ1 ...

A practical approach to meeting national obligations for sustainable trade under CITES
Conservation Biology, Volume 38, Issue 5, October 2024.Abstract Reconciling conservation goals with sustainable resource use requires adaptive management strategies. The Convention on International Trade in Endangered Species of Wild Fauna and Flora (CITES) regulates global trade for species listed on Appendix II, partly by requiring member countries (parties) to ensure exports do not damage wild ...
