International Journal of Applied Linguistics, EarlyView.ABSTRACT This qualitative multiple case study explores multilingual postgraduate students’ academic identities through writing at an EMI university in Hong Kong, with a focus on how they gain legitimacy in knowledge‑making with their multilingual repertoires. Grounded in a poststructuralist understanding of identities as fluid and negotiated, the study

基于结构健康监测的大直径球体高层支撑钢结构施工全过程性能评估
Jianzhu Gangjiegou Jinzhan基于结构性态健康监测系统数据，对大直径球体高层支撑钢结构体系进行施工全过程的结构监控。根据结构设计超限情况，进行了不同传感器的测点布设，建立了以应力、应变、倾角位移和温度传感器为基础的结构健康监测系统；结合结构全施工过程模拟分析，对比评价了构件及结构体系在各施工阶段的应力和变形，并分析了球体顶部穹顶结构提升过程中结构的力学性态变化。根据模拟分析结果，结合监测系统采集的实测数据，验证了施工期构件及结构体系的安全性，评价了施工全过程环境温度对结构性能的影响 ...

Jianzhu Gangjiegou Jinzhan, 2023 为实现网壳各节点抵抗荷载能力的均匀分布，提升结构稳定承载力，基于网壳结构受力特点，引入了单层网壳结构的杆件构形刚度参数。以结构杆件构形刚度均匀化为目标，将网壳杆件截面尺寸作为优化变量，采用惯性权重改进后的粒子群算法对网壳的杆件截面进行优化配置。优化结果表明，构形刚度方差能较为准确地反映结构的杆件构形刚度均匀程度。通过粒子群算法优化后求得的杆件配置可以使网壳结构接近于等稳定性，最大程度地提升结构的稳定极限承载力。

International Journal of Applied Linguistics, EarlyView.ABSTRACT In English Medium Instruction (EMI) contexts, students face simultaneous linguistic and academic demands. Although psychological capital (PsyCap) has been recognized as an important psychological resource for academic success, less is known about whether its effects depend on students’ academic English literacy (AEL).

Off‐Task Talk to Manage Relationship Work During Student Group Work in Second Language Classrooms
International Journal of Applied Linguistics, EarlyView.ABSTRACT This paper presents a conversation analytic study on student relationship work in off‐task talk (OTT) during group work in foreign language classrooms. Often seen as disengagement from tasks, OTT's social and relational functions in student classroom group interaction and formation remain underexplored.

Jianzhu Gangjiegou Jinzhan, 2015 抗弯钢框架结构(MRF)是目前研究最广泛、最流行的抗震系统,具有建筑灵活度高和施工效率高等优点。然而,这种结构常常缺乏足够的侧向刚度来限制结构的位移角,会导致在强震下结构和非结构构件产生严重的破坏。相反,偏心支撑钢框架结构(EBF)却有很大的侧向刚度来限制结构的位移角和有专属的抗震耗能构件。但是,支撑结构并不为建筑师所广泛接纳。为了结合抗弯钢框架结构和偏心支撑钢框架结构的优点,于2007年首次提出一种新型的抗震系统——连柱框架结构(LCF ...

Finetuning Pre‐Trained Language Models for Automatic Assessment of English‐Chinese Interpreting
International Journal of Applied Linguistics, EarlyView.ABSTRACT Recent years have seen growing interest in leveraging pre‐trained language models (PLMs) for automatic assessment of spoken‐language performance. Contributing to this emerging line of work, the present study offers the first attempt to finetune two PLMs, GTE‐multilingual and mmBERT, for assessing English‐Chinese interpreting, using over 1700 ...

Jianzhu Gangjiegou Jinzhan, 2019 局部火灾下,网架结构升温具有明显的非均匀性,结构中温度高的杆件热膨胀受到温度较低杆件的约束,使得网架结构的部分杆件具有显著的约束杆件高温力学特征。基于局部火灾下网架结构力学反应全过程数值追踪技术,考察结构升温非均匀性、结构荷载比、火源位置和结构跨度影响因素下,网架结构杆件高温屈曲后强度对整体结构抗火极限承载力的贡献。研究表明:当结构温度分布非均匀系数η在0.2≤η0.5时,杆件高温屈曲后强度对结构抗火极限承载力的贡献先逐渐减小然后转变为逐渐增大。上述研究结论可为建立网架结构第2阶段失效准则提供理论依据。
