International Journal of Applied Linguistics, EarlyView.ABSTRACT In English medium instruction (EMI), students face cognitive and emotional demands in second language (L2) communication, which may hamper their motivation and willingness to communicate (WTC). Adopting a mixed‐methods design, this study explores how growth mindsets affected student motivation (e.g., ideal L2 self and ideal disciplinary self ...

Dianci bileiqi对电气设备地震动响应分析应用较多的主要有两种方法——振型分解反应谱法和动力时程法，其中某些关键动力参数的取值在电气设备抗震相关规范中并没有具体规定，实际分析时往往凭个人经验，致使分析结果因人而异、不尽准确。为了在计算分析阶段通过对关键动力参数准确取值，尽可能真实获取结构动力响应，本研究以特高压支柱式电气设备颇具代表性的两种材质的结构本体及加装减隔震装置后的结构为分析对象，在非线性时程分析方面，通过对动力时程法主要参数：振型参与阶数、地震波及峰值加速度的影响对比分析 ...

International Journal of Applied Linguistics, EarlyView.ABSTRACT While English‐medium instruction (EMI) and English for Academic Purposes (EAP) courses are designed to promote language and content learning, their prevailing English‐only approaches often undermine students’ learning motivation. Against this backdrop, translanguaging has gained recognition as an effective pedagogical practice to support ...
