Exploring Chinese International Students’ Intercultural Competence in Australian University Classrooms: Challenges and Opportunities

open access: yesInternational 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 ...

海底光缆余长测试新方法可行性分析

open access: yesGuangtongxin yanjiu, 2012
光纤余长是海底光缆的重要性能指标,目前针对光纤余长的分析主要采用解析法,尚没有进一步精确分析光纤余长分布的实验方法。文章提出两种精确分析管内光纤余长分布的实验方法:高能射线法和光纤光栅法,并从理论上分析了这两种方法的可行性。

腐植酸复合肥中的氮、磷、钾含量分析

open access: yes, 2010
采用凯氏定氮法、磷钼酸喹啉容量法、ICP-AES法分别分析腐植酸复合肥的氮、磷、钾含量。研究结果表明,在添加不同酸时,应使盐酸的离子浓度大于硫酸的离子浓度,从而消除硫酸盐对磷分析的影响;待测液的酸度控制在1.0~1.6 mol/L为较适宜条件。方法具有良好的准确度和精密度,适用于腐植酸复合肥中氮、磷 ...

Assessing Argument Quality in L2 Argumentative Writing: Integrating Argument Elements and Intellectual Standards

open access: yesInternational Journal of Applied Linguistics, EarlyView.
ABSTRACT Many existing rubrics for L2 argumentative writing prioritize form‐based linguistic accuracy and complexity while insufficiently addressing substantive argumentative rigor and effectiveness. This limitation is further complicated by cross‐cultural variation in rhetorical conventions and educational practices, which challenge the direct ...

再分析研究方法浅谈

open access: yes, 1990
美国社会心理学家格拉斯(G.V.Glass)大概是最早提出再分析研究方法的学者。他认为,对于数据的分析可以概括为三种不同性质的活动:初步(primary)的分析,第二步(secondary)的分析和再分析(Meta-analysis)。在一项给定研究课题完成以后对所得数据的第一次分析为初步的分析。第二步的分析是在此基础上对研究结果的重复分析。在第二步的分析中往往可以运用到更合适的统计手段,从而能够在原有数据集合的基础上对一些新的问题作出回答。最后,如果研究者想把几项相互独立的研究结果整合起来作出结论 ...

The Pen is Mightier Than the Algorithm? A Multilevel Linguistic Comparison of LLM‐ and Human‐Translated Research Article Abstracts

open access: yesInternational Journal of Applied Linguistics, EarlyView.
ABSTRACT Translating local research into English as a lingua franca (ELF) connects local scholarship with global readership, but this process remains constrained by language barriers. Large language models (LLMs) offer advanced accessible solutions, but their responsible integration into academic translation requires a deeper understanding of the ...

单光子电离质谱法在线分析牙膏中的香精物质

open access: yes, 2012
在无需样品前处理的条件下,建立了直接进样单光子电离飞行时间质谱在线分析牙膏样品中香精物质的方法。本方法采用石英毛细管直接将样品导入质谱仪电离区,优化了电离区气压条件,并利用香精标准品的特征质谱信号对牙膏样品中香精成分进行了快速、准确鉴定,单个样品分析仅需0.5 min。将本方法应用于模拟刷牙过程中挥发性香精的在线、原位监测,考察了水含量对牙膏香精挥发过程的影响。结果表明,直接进样单光子电离飞行时间质谱法能够实时监控刷牙过程中挥发香精的成分与浓度,可以应用于其他样品如食品 ...
