The Development and Validation of the Chinese Vocabulary Levels Test
International Journal of Applied Linguistics, EarlyView.ABSTRACT In response to the increasing need for effective Chinese vocabulary assessments, this study developed the Chinese Vocabulary Levels Test (CVLT), a test designed for intermediate‐level Chinese as a second or foreign language (CSL/FL) learners, based on the vocabulary lists (levels 4–6) from the Chinese Proficiency Grading Standards for ...

International Journal of Applied Linguistics, EarlyView.ABSTRACT Collaborative writing has attracted increasing attention in English as a Foreign Language (EFL) instruction due to its potential to enhance learners’ writing competence. However, few studies have examined the comparative effects of collaborative versus independent writing on EFL learners’ individual performance, especially in higher‐order ...

Vocabulary Strategy Instruction in the Argentine EFL Context: Teachers’ Perspectives and Practices
International Journal of Applied Linguistics, EarlyView.ABSTRACT Despite extensive research on vocabulary strategy instruction (VSI), little has been known about teachers’ perspectives on how it is understood and implemented in practice. This study investigated Argentinian EFL teachers’ priorities in vocabulary instruction, their perceived knowledge of learner strategies for spoken vocabulary, and factors ...

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 ...

Rare Metals, Volume 45, Issue 11, November 2026.ABSTRACT This study systematically investigates the creep behavior of an Al19Co21Fe20Ni40 eutectic high‐entropy alloy (EHEA) at 500°C, focusing on the synergistic effects of heterostructure design and trace boron doping. Thermomechanical processing was employed to produce a heterostructure consisting of alternating lamellar and equiaxed regions.

Making Policy Evidence Traceable: A Modular Preregistration Framework for Policy Evaluation
Policy Studies Journal, Volume 54, Issue 4, November 2026.ABSTRACT Preregistration is increasingly used in policy research, but its value depends on whether preregistered commitments can be clearly linked to reported analyses. Policy studies often involve multiple outcomes, evolving administrative data, consequential design and analytic choices, and adaptive implementation, making it difficult to distinguish ...

Inverse Thermal Softening Behavior in a High‐Entropy Alloy Under Various Strain Rates
Rare Metals, Volume 45, Issue 10, October 2026.ABSTRACT Although face‐centered cubic high‐entropy alloys (HEAs) have received extensive attention and in‐depth research, most existing studies focus on single temperature or strain rate conditions, lacking systematic investigations into deformation mechanisms under extreme thermomechanical coupling environments.
