Finding floral and faunal species richness optima among active fire regimes
Conservation Biology, Volume 39, Issue 6, December 2025.Abstract Changing fire regimes have important implications for biodiversity and challenge traditional conservation approaches that rely on historical conditions as proxies for ecological integrity. This historical‐centric approach becomes increasingly tenuous under climate change, necessitating direct tests of environmental impacts on biodiversity.

The Future of AI in the GCC Post‐NPM Landscape: A Comparative Analysis of Kuwait and the UAE
Politics &Policy, Volume 53, Issue 6, December 2025.ABSTRACT Comparative evidence of how two Gulf Cooperation Council (GCC) states translate artificial intelligence (AI) ambitions into post–New Public Management (post‐NPM) outcomes are scarce because most studies focus on Western democracies. To fill this gap, we examine constitutional, collective choice, and operational rules that shape AI uptake in ...

Community‐informed and codesigned research to understand the impacts of railways on wildlife
Conservation Biology, Volume 39, Issue 5, October 2025.Abstract Trains cause mortalities of several animal species, but the ecological impacts of railways are understudied. Most research on wildlife–train collisions has focused on large mammals, but understanding railway‐specific risks for underrepresented taxa, especially vulnerable species, is important for developing effective mitigation strategies ...

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.

People and Nature, Volume 6, Issue 6, Page 2431-2448, December 2024.Abstract How humans connect with nature impacts the well‐being of both people and ecosystems. Being disconnected from nature can lead to attitudes and behaviours that ultimately damage our physical and mental health and cause irreparable harm to the planet.

Journal of Linguistic Anthropology, Volume 34, Issue 3, Page 441-469, December 2024.Abstract This paper develops the concept of “indexical deprivation” from the experiences of English learning in relation to cochlear implant use among Taiwanese deaf adults. Based on the framework of language ideological assemblage, this paper traces how institutional discourses and practices at different levels contribute to the indexicalization ...

Rare Metals, Volume 43, Issue 8, Page 3702-3712, August 2024.Graphical abstract AbstractThe highly reversible insertion/extraction of large‐radius K+ into electrode materials remains a tough goal, especially for conversion‐type materials. Herein, we design a current collector‐integrated electrode (N–CoSe/CoSe2–C@Cu) as an advanced anode for potassium‐ion battery (PIBs).

Shiyou jixie, 2015 为了研究离心泵发生空穴后的工作性能，将Singhal空穴模型和Mixture多相流模型相结合，运用RNGκε湍流模型和SIMPLE算法对离心泵的三维流场进行计算流体动力学数值模拟，并预测其性能曲线。研究结果表明，压力自叶片工作面的根部向尾部逐渐增大，然后从背面的尾部向根部不断下降，在入口端容易发生空穴。空穴的临界条件为泵入口压力58 104 Pa或出口压力187 792 Pa。当泵发生空穴时，叶轮内的流线偏离叶片型线，并在流量下降时出现大尺度漩涡，造成泵的扬程和效率急剧下降。在设计流量下 ...

Zhendong Ceshi yu Zhenduan为了揭示钢筋混凝土（reinforced concrete，简称RC）空心板抗弯承载性能与其振动频率之间的关系，从实桥上拆取了3片服役27年、全长为11.20 m的RC空心板，通过实桥原位试验和室内分级加载静、动力试验，获取了空心板的抗弯承载性能参数和前3阶振动频率，并分析了空心板荷载、挠度、刚度与竖弯频率间的关系，拟合得到了1阶频率比‑荷载比、1阶频率比‑割线刚度比的函数表达式。研究表明：3片板的荷载‑挠度曲线具有明显的双折线特征，在不同加载状态下前3阶振动模态始终为1阶竖弯（对称）、2阶竖弯（反对称）
