Exploring English Language Learners’ Vocabulary Knowledge and Usage When Speaking
ABSTRACT Vocabulary forms a fundamental component of speaking ability, as it enables speakers to convey meaning accurately, fluently, and effectively. Although the relationship between vocabulary and speaking has been investigated to some extent, gaps remain in understanding the link between learners’ vocabulary knowledge and their speaking proficiency,

Co‐Teaching in a Virtual Intensive Study Language Programme: Insights From Team Ethnography
ABSTRACT As virtual study abroad becomes an increasingly important form of international education, little is known about how transnational teaching is organised and sustained across institutions. Using activity theory as an analytical framework and team ethnography as methodology, this study examines a virtual intensive study (VIS) programme delivered

针对钻井过程中循环钻井液流量控制不准确,造成螺杆钻具旁通阀总成无法开启闭合,阀心密封件失效刺漏等问题,通过φ244 mm等壁厚螺杆钻具旁通阀理论计算和循环试验,验证旁通阀工作可靠性。测得φ244 mm等壁厚螺杆钻具旁通阀关闭流量和开启流量;测得不同流量下旁通阀压降,确定阀心实际流量系数。分析结果表明,φ244 mm等壁厚螺杆钻具旁通阀在不同流量下产生的压差与循环试验获得压差十分接近,并且旁通阀在一定流量下均能实现阀心顺利打开和关闭。当流量由大变小时,阀心打开流量为20.20~14.60 L/s ...

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

Finetuning Pre‐Trained Language Models for Automatic Assessment of English‐Chinese Interpreting
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 ...

为了提高模块化多电平变流器MMC(modular multilevel converter)的稳定性与动态性能,实现环流抑制,提出基于交流电流和环流双目标调节的无差拍控制。通过MMC单相等效电路的动态方程,设计MMC交流电流分量以及环流分量的无差拍电流预测控制器,并针对实际控制存在的时延问题进行理论分析提出改进措施。通过搭建无差拍控制下模块化多电平变流器的十电平Simulink仿真模型,验证控制策略的有效性。结果表明:通过无差拍控制可以显著提高模块化多电平变流器的稳态和动态性能 ...

Resource Substitution: Local Governments' Issue Attention and Policy Reinvention
ABSTRACT Research on policy reinvention, where a government modifies rather than replicates policy innovations introduced by other governments, has progressed significantly, but how it is influenced by the government's issue attention has not been thoroughly examined.

ABSTRACT This paper examines the practices ordinary social media users employ to influence the content served to them by platform algorithms, and the relationship between these practices and levels of algorithmic literacy. Practices were documented across TikTok, Facebook, Instagram, Twitter (now X), YouTube and Reddit during 65 sessions, conducted as ...
