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.

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

Gaoya dianqi, 2020 在断路器所有故障中,机械故障占有相当大的比重,对其机械特性在线监测具有重要现实意义。文中针对某12 kV交流中压真空断路器,以分合闸线圈电流信号、角位移信号及振动信号为监测对象,研制了一种以STM32F407为主控芯片、搭载RT-Thread实时操作系统的交流中压真空断路器机械特性在线监测装置。该装置采用HNC-661霍尔电流传感器捕获分合闸线圈电流,判断断路器分合闸的动作起始时刻;在低电位处采用WDD35D4-5kΩ角位移传感器替代直线位移传感器间接测量动触头的位移曲线 ...

Policy Studies Journal, EarlyView.ABSTRACT Despite extensive research on policy diffusion, the ways in which policy attention influences this process remain underexplored. This study addressed this gap by distinguishing between three types of policy attention—political speeches, policy issuance and field visits—and investigating their differential impacts when delivered by central and ...

Dizhen xuebao, 2019 鉴于传统的地震动强度表征参数（IM）不能有效地反映速度脉冲型地震动的破坏特征，需要研究能够在全周期段内表征速度脉冲型地震动强度的参数。本文首先从NGA-West2强震数据库中选取了236条速度脉冲记录，分析了42种地震动参数之间的相似性和相关性，初步给出了速度脉冲型地震动强度的表征参数；其次，利用单自由度体系动力时程分析方法，研究了不同延性μ条件下速度脉冲型地震动强度表征参数与最大非线性位移um之间的相关性系数随周期T的变化特征 ...

The Inclusion Trade‐Off: Comparing the Design and Functionality of Collaborative Governance Forums
Policy Studies Journal, EarlyView.ABSTRACT Environmental challenges require collaboration across jurisdictions, often through forums or intermediary spaces for repeated interaction. A persistent forum design question concerns inclusion criteria, or which actors should be included.

Unpacking Welfare Deservingness Theory: Evidence From the Perceived Deservingness of Gig Workers
Policy Studies Journal, EarlyView.ABSTRACT The theory of welfare deservingness provides valuable insights into the social legitimacy of welfare programs and the principles underlying policy design. In examining the question of who deserves what and why, established deservingness criteria emphasize that individuals demonstrating motivation to work (“reciprocity”) are typically perceived
