Configuration Optimization Design of Magnetic Circuit for Large Magnetostrictive Devices Based on TbDyFe Alloy

open access: yesRare Metals, EarlyView.
ABSTRACT Reliable operation of high‐performance magnetostrictive devices, composed of the giant magnetostrictive material (GMM), that is, the TbDyFe alloy, critically depends on an optimally tailored bias magnetic field. Sufficient intensity and uniformity are essential to induce the ideal initial strain in the GMM, enabling peak reciprocating output ...

Climate stability drives multidimensional nestedness of amphibian assemblages in a Chinese sky island system

open access: yesFunctional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract The nested subset pattern (nestedness) has been widely used to explain species distributions in island and fragmented systems. Mountain sky islands serve as critical natural laboratories for understanding the evolutionary consequences of geographic isolation and climate

Profiling Metacognitive Knowledge and Growth Mindset in EFL Vocabulary Learning

open access: yesInternational Journal of Applied Linguistics, EarlyView.
ABSTRACT Guided by the self‐regulated learning (SRL) framework, the present study investigates the associations between metacognitive knowledge and growth mindset in EFL (English as a Foreign Language) vocabulary learning, addressing a critical gap in the literature. While metacognitive knowledge, comprising person, task, and strategy dimensions, plays

Synthesizing Empirical Research on Learner Metacognition in Second Language Writing

open access: yesInternational Journal of Applied Linguistics, EarlyView.
ABSTRACT Despite considerable research interest in learner metacognition in second language (L2) writing, there is not yet a review that synthesizes the existing empirical findings and discusses their implications. To fill the void, this systematic review synthesized 39 empirical studies on learner metacognition in L2 writing and examined their salient

Decoding Paradoxes in Digital Government: Strategies for the Pursuit of Public Value

open access: yesPublic Administration, EarlyView.
ABSTRACT This study aims to analyze the complexities of paradoxes in digital government. Through a focused analysis of 34 selected articles, adhering to PRISMA guidelines, it codifies seven paradoxes, categorized into “internal governance paradoxes” and “external engagement paradoxes.” These paradoxes arise from conflicting values among governments ...

Using Cultural Theory to Specify the Policy Actors, Belief Systems, and Sources of Coalition, Conflict, Stability, and Change in Policy Advocacy Coalitions and Environmental Resource Policies

open access: yesPolicy Studies Journal, EarlyView.
ABSTRACT We use grid‐group cultural theory (CT) to specify underspecified aspects of the Advocacy Coalition Framework (ACF). Our theoretical synthesis of CT and the ACF provides, first, an exhaustive typology of policy actors and their cultural cognitive biases that entail, guide, and constrain policy core beliefs about problem definitions and ...

Deeper sociological insight needed for behaviour change: A systematic review of Chinese ivory consumption

open access: yesPeople and Nature, Volume 8, Issue 2, Page 270-282, February 2026.
Abstract Chinese consumer demand for ivory threatens vulnerable African elephant populations, despite long‐standing efforts to combat the illegal wildlife trade. Behavioural science approaches have been proposed to address these systemic behaviours. However, their robust use remains uncommon in demand management interventions.

120株复发肺结核患者结核分枝杆菌耐药性分析

open access: yesZhongguo shiyan zhenduanxue, 2015
目的本研究对复发肺结核患者结核分枝杆菌耐药性进行分析,为相关的临床治疗提供参考。方法本文对我院2010年2月至2014年2月期间诊治的120例复发性肺结核患者分离的菌株进行耐药性分析,并对前后两次发病菌株进行散在分布重复单位(MIRU)进行基因型分型。以120例同期初治肺结核患者为对照组,比较两组患者之间结核分枝杆菌的耐药性差别。结果女性患者分离菌对抗结核药物耐药率更高 ...
