Methods in Ecology and Evolution, Volume 11, Issue 1, Page 22-37, January 2020., 2020 Abstract Climate change is a world‐wide threat to biodiversity and ecosystem structure, functioning and services. To understand the underlying drivers and mechanisms, and to predict the consequences for nature and people, we urgently need better understanding of the direction and magnitude of climate change impacts across the soil–plant–atmosphere ...

Beyond Motivation: Modeling the Predictive Role of L2 Pride in Informal Digital Learning of English
International Journal of Applied Linguistics, Volume 35, Issue 4, Page 1938-1952, November 2025.ABSTRACT This study investigates the role of second language (L2) pride—an understudied affective factor—in shaping learners’ language learning motivation and involvement with informal digital learning of English (IDLE). Drawing on questionnaire data from 1388 Chinese university EFL students, the study employs structural equation modeling to examine ...

Methods in Ecology and Evolution, Volume 15, Issue 11, Page 1926-1939, November 2024.Abstract Simulation studies are essential tools to assess statistical methods. Functioning as controlled experiments, simulations generate data from known underlying processes. However, unclear or incomplete reporting of simulation studies can impact their interpretability and reproducibility, potentially leading to the misuse of statistical methods ...

Gaoya dianqi, 2013 电容器爆裂严重威胁了电力系统运行的安全性,因此有必要研究电容器耐爆能量试验。为了建立该试验系统,依据耐爆试验理论分析,首先搭建整套试验回路,并选用合适的测量设备和光电隔离方法实现数据的实时采集,接着根据试验电流波形的差异,列出不同的注入能量计算方法,并对其进行适用性分析,得出最佳的能量计算方法。通过采用EWB软件进行试验过程的模拟仿真,得出仿真波形并与试验的实测波形进行对比,结果表明仿真波形与实测波形基本一致,能量计算具有可信度。该试验系统的建立表明了电容器外壳耐爆能量试验及能量计算的关键技术点已经掌握,
