Learning Styles, Engagement and Anxiety in AI‐Mediated Writing: A Multimodal Feedback Study
International Journal of Applied Linguistics, EarlyView.ABSTRACT Artificial intelligence (AI) tools now permeate English academic writing. However, evidence on how feedback modalities align with student differences and with psychological mechanisms remains limited. Prior work often reduced learning styles to simple matches with delivery modes and treated learning engagement and writing anxiety as peripheral.

International Journal of Applied Linguistics, EarlyView.ABSTRACT This study examines multilingual practices in research interviews, focusing on English lexical insertions in Chinese‐language research interviews with teachers of Chinese in Australian secondary schools, and treating these code‐switches as analytically meaningful rather than incidental.

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 ...

Zhongshan Daxue xuebao. Yixue kexue ban, 2023 目的探讨磁共振表观弥散系数（ADC）评估磁共振引导聚焦超声术（MRgFUS）治疗子宫肌瘤效果的价值。方法回顾性分析佛山市中医院2018年1月至2022年10月期间56例接受MRgFUS治疗子宫肌瘤患者治疗前、治疗3月后和6月后的MRI及临床资料，比较患者病灶ADC值与肌瘤的体积，症状严重评分（SSS）和子宫肌瘤症状-生活质量问卷（UFS-QOL）评分的相关性。使用方差分析比较治疗前后相关数据的差异，采用Pearson法进行数据的相关性分析。结果56例患者治疗前及治疗3个月后、6个月后病灶ADC值［（1 ...

International Journal of Applied Linguistics, EarlyView.ABSTRACT With the increasing number of Chinese international students in Australian universities, intercultural competence has become a critical factor influencing their interactions with Australian tutors in university classroom settings. Existing research often examines students’ intercultural competence from a single‐method or single‐perspective ...

Gaoya dianqi, 2016 准确辨识超级电容器特征参数值是分析超级电容器电气特性和估计其健康状态的重要研究基础。为克服采用阻抗谱分析法辨识特征参数所需激励信号幅值过小,且不能反映研究对象真实工况以及难以实现在线辨识特征参数的缺点,文中采用递推最小二乘法解决此问题。基于实验分析结果发现直接采用该算法辨识出的参数值与真实值差异较大,因此在深入分析辨识算法的基础上,对最小二乘法的辨识结构加以改进。实验和仿真分析结果表明,基于改进后的最小二乘法辨识得到的超级电容器特征参数值更加准确和可信。

Public Administration, EarlyView.ABSTRACT As the public sector increasingly adopts AI‐powered automated decision systems (ADS), understanding how citizens experience and value ADS use in public decision‐making is both normatively and practically important. Therefore, we examine and compare the effects of seven attributes of public values on citizens' support for ADS adoption in two ...
