International Journal of Applied Linguistics, EarlyView.ABSTRACT Understanding learners’ English speaking self‐efficacy is essential for promoting effective oral communication in EFL contexts. However, variable‐centered research on English speaking self‐efficacy often overlooks heterogeneity among learners.

International Journal of Applied Linguistics, EarlyView.ABSTRACT Grounded in social cognitive theory, this study investigated how high‐evidence factors jointly contribute to Chinese‐as‐a‐foreign‐language (CFL) speaking self‐efficacy. Data from 236 CFL learners in Beijing revealed a multifaceted pattern of associations.

Leveraging an Unhappiness Lens for Smarter Policies
Policy Studies Journal, EarlyView.ABSTRACT Traditional policy research has largely focused on enhancing happiness or well‐being, privileging positive outcomes as the primary metric of success. We argue that a systematic focus on the drivers of unhappiness—rather than solely on happiness—offers a complementary analytical framework that can uncover hidden societal deficits and broaden ...

Journal of Critical Infrastructure Policy, Volume 8, Issue 1, Spring/Summer 2027.ABSTRACT Epistemic orphaning, responsibility drift, loss of institutional memory, and non‐stationarity are not new problems in infrastructure governance—they have accompanied long‐life infrastructure throughout its history. What artificial intelligence changes is not the existence of these problems but their scale, opacity, and the structural ...

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 ...

智能科学与技术学报, 2019 模糊系统作为一种万能逼近器具有很强的可解释性，已被广泛应用在各个领域。尽管目前模糊系统的理论研究不够成熟，仍然存在诸如规则太多、优化困难、维度诅咒等问题，难以处理高维大数据。尽管深度神经网络取得了突出进展，能很好处理图像和语音等大数据，但其可解释性不好，难以用于安全相关的重要场合。因此，非常有必要研究一种基于模糊系统的可解释性强的人工智能算法。结合深度神经网络和模糊系统两者的优点，研究深度模糊系统及其算法，将有可能解决高维大数据问题。主要对模糊系统的发展历程与研究进展分别进行详细阐述 ...

Review of Policy Research, Volume 43, Issue 6, November 2026.ABSTRACT The EU policy framework for nature restoration has undergone a significant change with the adoption of the Nature Restoration Regulation. Since 2022, the EU has developed a new comprehensive and continent‐wide legislation to restore degraded ecosystems and halt biodiversity loss, which came into force in August 2024 and is an integral part of ...

Haiyang gongcheng zhuangbei yu jishu, 2019 时移地震解释技术可有效地解释流体变化引起的时移地震差异，预测剩余油分布和指导油藏管理，其解释精度直接影响深海油田的开发效果。常规时移地震解释技术以岩石物理模型为基础，根据时移地震的响应差异定性确定流体替换范围，半定量确定流体替换程度，未能完全实现定量化解释。为了提高时移地震差异解释的精度，形成一种基于敏感流体因子的时移地震定量解释技术。通过叠前弹性参数反演结果筛选出敏感流体因子，在两次地震采集时间点的敏感流体因子基础上，通过岩石物理模型分别将两次敏感流体因子转换为油藏参数 ...

Rare Metals, Volume 45, Issue 10, October 2026.ABSTRACT Improving the efficiency and stability of oxygen evolution electrocatalysts remains essential for advancing water splitting technologies. Although in situ surface reconstruction into active phases is desirable, it often leads to uncontrolled structural degradation.

Rare Metals, Volume 45, Issue 10, October 2026.ABSTRACT Zinc‐based biodegradable metals are promising implant materials, and additive manufacturing offers a powerful route for their patient‐specific fabrication. However, process‐induced surface defects can accelerate degradation and compromise biocompatibility, rendering post‐processing essential.
