A Systematic Scoping Review of Self‐Regulated Learning With AI in Language Education

open access: yesInternational Journal of Applied Linguistics, EarlyView.
ABSTRACT The rapid development of artificial intelligence (AI) technology has brought new opportunities for second/foreign language (L2) education while also raising concerns about the use of AI tools. This systematic scoping review provides a snapshot of the current state of research situated at the intersection of self‐regulated learning (SRL) and AI

鸱鸮科27种鸟类COⅠ序列变异及系统发育分析

open access: yes野生动物学报, 2016
鸱鸮科鸟类的种属分类仍存在一些争议。例如:渔鸮属和雪鸮属是否应并入雕鸮属,四川林鸮是一独立种还是长尾林鸮的一个亚种?线粒体 DNA 中细胞色素 C 氧化酶亚基I(CO I)基因是 DNA 条形编码的主要基因,被广泛应用于鸟类的物种鉴定和系统发育研究。通过测定中国产红角鸮、雕鸮和长尾林鸮COⅠ基因的序列,并结合 GenBank中鸱鸮科鸟类的同源序列,本文对27 种鸟类进行了序列变异和系统发育分析。结果显示,鸱鸮科鸟类多数是种间变异大于种内变异,该科鸟类几乎都是同属的优先聚类 ...

Survey of viral diversity in the sediments of South China Sea [PDF]

open access: yes, 2016
病毒是海洋生态系统中丰度最大,多样性最为丰富的微生物颗粒。海洋沉积物中的病毒丰度相比较海水中,要高1~2个数量级,并且其形态和基因型也更加多样。目前,人们对海洋沉积物中的病毒相关研究还比较少。为了增强对海洋沉积物中病毒的了解,本论文利用荧光显微镜法获得了珠江口沉积物以及南海北部和西部沉积物中病毒的丰度数据,并且通过病毒标记基因(g23&psbA)PCR扩增、克隆文库测序等分子技术获得了沉积物中T4类噬菌体和噬藻体类群的多样性信息。主要的研究结果: (1)荧光显微镜检测结果显示珠江口沉积物中病毒(4.49×

Artificial Intelligence for Language Learning: A Systematic Review of its Design, Theoretical Foundations, Implementation, and Impact

open access: yesInternational Journal of Applied Linguistics, EarlyView.
ABSTRACT Although the use of AI technologies (e.g., chatbots and automated writing evaluations (AWE)) has gained considerable attention in language learning fields in recent years, how AI technologies have been designed and implemented in language learning education, as well as their effectiveness, is understudied.

Taxonomy, distribution and comparative study of thermal tolerance in Nipponacmea limpets along China coast [PDF]

open access: yes, 2015
作为生物圈最脆弱的系统之一,潮间带生态系统是研究全球变化对群落动态影响的理想系统。全球变化带来的环境变化如温度升高、海水酸化和海平面升高等可影响生物行为、生理以及进化适应,从而改变潮间带生物的种群动态和群落结构。而面对环境变化,物种间由于适应能力的差异,会出现“胜利者”和“失败者”。背尖贝(GenusNipponacmea)是常见潮间带生物,广泛分布于我国沿海中-高潮间带岩石上。本研究利用DNA条形码研究中国沿岸背尖贝的分类、系统发育以及地理分布格局,并测定不同温度下背尖贝属间生理和分子适应的差异 ...

Profiling Metacognitive Knowledge and Growth Mindset in EFL Vocabulary Learning

open access: yesInternational Journal of Applied Linguistics, EarlyView.
ABSTRACT Guided by the self‐regulated learning (SRL) framework, the present study investigates the associations between metacognitive knowledge and growth mindset in EFL (English as a Foreign Language) vocabulary learning, addressing a critical gap in the literature. While metacognitive knowledge, comprising person, task, and strategy dimensions, plays

青海湖裸鲤的起源和花斑裸鲤的种群演化 [PDF]

open access: yes, 2007
通过线粒体Cytb基因全序列分析,探讨了青海湖裸鲤和花斑裸鲤的起源关系及其进化模式.系统发育分析进一步支持了青海湖裸鲤和花斑裸鲤3个mtDNA谱系的划分.形态上具有高鳃耙变异的个体未形成特有的进化枝,证明了第一鳃弓外鳃耙变异并不具有系统发育意义.对青海湖裸鲤和花斑裸鲤进化枝扩散模式的网络分析表明,黄河独有的单倍型A1是一个创立者单倍型,全部青海湖裸鲤的样品来自于它的辐射,而青海湖裸鲤可能仅仅起源于黄河花斑裸鲤两个主要支系中的一个 ...

The Emotional Valence Paradox in Social media: A Computational Linguistic Analysis of How Sentiment, Emotion, and Content Domain Predict Social Comparisons on Rednote

open access: yesInternational 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; (

Diversity of culturable endophytic fungi of common reed ( Phragmites australis) in coastal wetland [PDF]

open access: yes, 2016
内生真菌在植物生长以及抵御环境胁迫过程中起着非常重要的生态作用.本研究从黄河三角洲滨海湿地1350个芦苇组织切片中分离得到318株内生真菌,通过对rDNA ITS的分型、测序及系统进化分析,研究了该地区芦苇植株根、茎、叶中可培养内生真菌的种类组成及在不同盐度、不同组织中的分布情况.根据序列相似性(以98%为阈值),共获得12个真菌分类操作单元(OTUs).在门级分类水平上,子囊菌门为绝对优势菌群,在各组织和站位中均有分布.芦苇根组织中分离得到的内生真菌OTU数相对较多 ...

Reconceptualising Motivation as Material‐Semiotic Entanglements: Translanguaging in Graduate TESOL Education

open access: yesInternational Journal of Applied Linguistics, EarlyView.
ABSTRACT Multilingual students in Anglophone universities often operate in survival mode. While translanguaging supports learning, critical gaps remain in understanding how translanguaging pedagogies transform and sustain motivation in English‐dominant contexts.
