Language Mindset and Discipline Mindset Both Matter: Exploring the Effect of Growth Mindset on Motivation and Willingness to Communicate in EMI Higher Education

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 ...

电热应力对硅油产气特性协同效应的实验研究

Gaoya dianqi
实验室中常采用加速老化方法获得硅油的老化试样，并根据试样中溶解气体组分及体积分数判断硅绝缘油的老化状态，但当前实验中仅能施加热应力或电应力，不能较好地反映硅油的真实工况。为解决这这一问题，文中开展了电热应力对硅油产气特性协同效应的实验研究。文中针对PMX-200型硅油，在200 ℃、25 kV下设计了硅油的热电老化、电热老化和电热联合老化等3组加速老化实验，通过对试样中的气体组分及体积分数分析，发现热电老化方式与电热联合老化方式下试样中溶解气体组分及体积分数最为接近，误差在7.41%~16.86%之间 ...

GLP-1、Betacellulin、Activin A、bFGF 和 Nicotinamid 联合诱导小鼠胚胎干细胞分化为胰岛素分泌细胞

Zhongshan Daxue xuebao. Yixue kexue ban, 2004
【目的】探讨体外联合应用GLP-1、betacellulin、activinA、bFGF和nicotinamide5种生长因子能否将小鼠胚胎干细胞(ES细胞)诱导分化为胰岛素分泌细胞。【方法】以GLP-1、betacellulin、activinA、bFGF和nicoti-namide5种生长因子诱导E14.1小鼠ES细胞30d后,应用RT-PCR、DTZ染色和免疫组化检测分化细胞胰岛素表达,以流式细胞仪检测胰岛素分泌细胞的分化率,用RIA法测定培养液中胰岛素水平。【结果 ...

From “Striving to Survive” to “Striving to Thrive”: A Narrative Inquiry Into a Student's Motivational Development via Translanguaging in EAP and EMI Contexts

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 ...
