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

Learner‐Focused Strategy Instruction From the Teachers’ and the Learners’ Perspective
International Journal of Applied Linguistics, EarlyView.ABSTRACT Numerous large‐scale quantitative studies have been conducted to yield a macro‐level picture of the effectiveness of strategy instruction. However, little is understood about learners' actual processing of strategy instruction and interaction with the teachers delivering it.

腺苷A2A受体阻断剂SCH58261对大鼠杏仁核点燃癫痫模型的影响
Zhongguo shiyan zhenduanxue, 2015 目的研究腺苷A2A受体阻断剂SCH58261对大鼠杏仁核点燃癫痫模型的作用。方法制作杏仁核电刺激模型。点燃成功后的大鼠,通过腹腔给药的方法,观察SCH58261对模型成功后各发作参数的作用。整个实验过程中,严密观察药物对大鼠行为学的影响。结果在成功点燃的癫痫模型中,SCH58261（0.005,0.05,0.5mg/kg）对全面性发作阈值（GST）没有影响。以GST（+4μA）为刺激强度,SCH58261（0.005,0.05mg/kg）可以降低杏仁核后放电时间（ADD）,运动性发作持续时间（MSD ...

不同滴灌带布设方式对苹果-大豆间作系统土壤化感物质与微生物的影响
Shuitu Baochi Xuebao, 2023 为探究不同滴灌带布设方式对果农间作系统土壤酚酸类物质、酶活性和微生物分布特性影响,初步探明间作滴灌条件下,土壤酚酸类物质与土壤生物因子的相互关系。以晋西黄土区典型的苹果-大豆间作系统为研究对象,设置3种(L1、L2、L3)滴灌带间距,分析不同水分分布下土壤酚酸类物质、酶活性和微生物数量的空间分布变化,并在相关性基础上利用逐步回归模型,分析3个土壤因子之间的相互关系。结果表明:除苯甲酸和间苯三酚外,滴灌带间距对酚酸类物质分布影响显著 ...
