International Journal of Applied Linguistics, EarlyView.ABSTRACT Second or foreign language (L2) speaking is a key aspect of L2 competence. While GenAI shows potential to address challenges in L2 speaking development, its role remains insufficiently understood. Self‐Determination Theory (SDT) could explain student language learning engagement. Therefore, this systematic review examines how GenAI affordances

吉林省地区朝鲜族和汉族健康人群LPL基因HindⅢ酶切位点多态性分布的研究
Zhongguo shiyan zhenduanxue, 2010 目的分析我国吉林省地区朝鲜族和汉族健康人群脂蛋白酯酶（lipoprotein lipase,LPL）基因HindⅢ酶切位点多态性的分布。方法应用聚合酶链反应（polimerase chain reaction,PCR）等技术检测66例朝鲜族和90例汉族LPL基因多态性,并将其基因型和等位基因在两族人群中的分布进行统计学分析。结果朝鲜族人群LPL基因P+P+基因型,P+P-基因型和P-P-基因型频率分别为57.58%,33.33%和9.09%;汉族人群分别为73.33%,24.44%和2.22 ...

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.

Zhongguo shiyan zhenduanxue, 2010 目的利用基因芯片筛选与精子发生相关的基因,并研究其表达特征。方法将4 d、9 d、18 d、35 d、54 d和6月龄小鼠睾丸组织cDNA与Affymetrix全基因组芯片进行杂交,筛选出差异表达的基因。通过RT-PCR分析差异表达基因在小鼠睾丸不同发育阶段中的表达。结果分析Affymetrix全基因组芯片杂交结果后,筛选得到1个差异表达杂交点,通过在NCBI网站与小鼠全基因组序列Blast分析可知该差异表达基因是Rfx2基因。该基因在4 d、9 d、18 d、35d、54 ...

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
