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, 2016 电涌保护器（SPD）在工作状态下会产生一定的泄漏电流,其泄漏电流的值可以反应SPD的老化程度。针对SPD的老化预测问题,利用其产生的泄漏电流,提出一种基于灰色预测模型的SPD老化预判方法。研究表明:灰色预测模型可以较好地应用于SPD泄漏电流的预测中,预测结果误差较小,具有较高的有效性和实用性,从而为SPD老化预判提供一种可能。此外,为电网电力系统中其他设备状态预判提供了一种崭新思路。

Rate Adaptive LDPC Coded Communication over Underwater Acoustic Channels [PDF]
, 2016 水声信道的频带资源十分有限，在中长距离下，通常只有几kHz的带宽供水声通信使用。现有水声通信系统大多采用码率固定的信道纠错编码方法，而且为了确保在恶劣水声环境中的通信可靠性，码率一般设置得较低。显然，这种码率固定的通信方式频带利用率较低，在带宽十分有限的水声通信中是十分不利的。针对该问题，论文提出一种码率自适应的水声低密度奇偶校验（LDPC）编码通信方法，仿真和实验研究了该通信方法的性能。 论文主要研究内容如下： (1)较详细介绍了LDPC码的编码、译码和不同码率LDPC码的构造方法。构造了码率分别为0.

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; (

, 2016 沙波运移预测是海洋开发必不可少的一环。通常采用非线性谱分析方法分析沙波实测资料从而预测沙波运移。然而这种方法仅是从统计的角度进行预测,它不包含水动力、加载风速、沙质底床性质等关键因素对沙波运移的影响。对此本文提出了一种谱分析模型解决此类问题。该模型基于沙波形状不变假设,引入波谱能量平均运移速度,考虑了台风产生的风浪和涌浪,利用波浪输沙理论计算台风期间的沙波运移,厘清了一般波流作用和台风作用引起的沙波位移。模型计算结果与实测数据吻合,可以用来预测10 ...

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 ...

The Return Predictability for the Chinese Stock Market Based on Predictive Regression [PDF]
, 2016 中国的股票市场发展到现在，不论在总市值还是在参与人数上都达到了相当大的规模。股票市场收益率作为投资者最为关心的话题，其预测研究不仅具有理论意义，同时具有非常深刻的现实意义。理论上，股市收益率的预测与市场有效性及资本资产定价等理论相联系。现实中，股市收益率的预测可用于测度资金成本以及用于指导投资组合决策。因此，股市收益率的预测研究是一个很有意义的主题。 本文基于2000年1月4日至2014年12月31日的日交易数据，利用预测性回归模型对中国股市收益率进行了预测研究。从两个层面选取经济变量以及构造技术指标 ...

International Journal of Applied Linguistics, EarlyView.ABSTRACT Collaborative writing has attracted increasing attention in English as a Foreign Language (EFL) instruction due to its potential to enhance learners’ writing competence. However, few studies have examined the comparative effects of collaborative versus independent writing on EFL learners’ individual performance, especially in higher‐order ...

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 ...
