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.

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 This computational linguistic study analyzes 8743 Rednote posts to examine how sentiment, emotion, and content domain collectively shape social comparison dynamics on social media. We identify four key findings: (1) an emotional gradient, where upward comparison content exhibits the highest sentiment scores and downward comparison the lowest; (

Jixie chuandong, 2007 在对修形量产生的回程误差深入分析的基础上,提出了一种适用于高精度针摆传动最佳修形齿廓的概念,对采用”负等距+正移距”修形方法获得最佳修形齿廓的原理进行了深入探讨,根据编制的相应计算软件,可以方便地迭代出满足预定几何回程角时的修形量。基于传动承载时摆线轮针齿啮合、柱销柱销孔啮合时变形协调原理,完成了整个传动过程的动态回程误差分析,完善了回程误差分析计算数学模型。

Mobile data visual analysis for human activity understanding(面向用户行为理解的移动通讯数据可视分析)
Zhejiang Daxue xuebao. Lixue ban, 2018 通信数据包含人类活动的时空以及社会关系等信息，对人类行为分析有重要的价值.为了帮助分析者对用户的行为进行分析和理解，构建了从通信数据中探索用户的时空、社交等信息以分析用户行为的可视化流程，旨在理解用户的行为模式并通过行为的对比发现用户的社会角色以及用户之间的真实社交关系，通过迭代式交互过程，对用户不同时段的行为进行有效的理解和分析.在此基础上，构建了用户行为可视分析系统，采用半年的通信数据对该方法以及系统进行评估，结果显示，本方法能够有效理解个人行为、识别用户之间的关系.

Synthesizing Empirical Research on Learner Metacognition in Second Language Writing
International Journal of Applied Linguistics, EarlyView.ABSTRACT Despite considerable research interest in learner metacognition in second language (L2) writing, there is not yet a review that synthesizes the existing empirical findings and discusses their implications. To fill the void, this systematic review synthesized 39 empirical studies on learner metacognition in L2 writing and examined their salient

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.

Jianzhu Gangjiegou Jinzhan对于大型复杂空间钢结构，可靠的施工过程分析对保障施工安全性和钢结构安装质量具有重要意义。在传统施工过程分析与钢结构直接分析的基础上，提出一种考虑构件和安装模块初始缺陷以及变形累积的钢结构非线性施工过程分析方法。利用NIDA软件将该方法应用于成都某大悬挑钢桁架结构的施工过程分析中，确保了施工方案的可行性。同时，对比分析了非线性施工过程分析、一次成型分析和线性施工过程分析3种分析工况下结构关键节点位移及构件应力情况，并与施工实测值进行了比对。结果表明，一次成型分析与线性施工过程分析的位移较实测值偏小 ...

International Journal of Applied Linguistics, EarlyView.ABSTRACT Many existing rubrics for L2 argumentative writing prioritize form‐based linguistic accuracy and complexity while insufficiently addressing substantive argumentative rigor and effectiveness. This limitation is further complicated by cross‐cultural variation in rhetorical conventions and educational practices, which challenge the direct ...
