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 ...

AI foundation models in plant biology
New Phytologist, EarlyView.Foundation models decode genomes, engineer proteins, phenotype crops, and drive AI agents across plant biology. This figure was created in BioRender (BioRender.com/xcmmkel). Summary Rapid technological progress has enabled plant biologists to accumulate unprecedented volumes of multi‐scale, multi‐modal data, yet this abundance of data has intensified ...

, 1987 本文从Reissner圆柱壳理论出发,应用摄动法获得了含轴向裂纹圆柱壳裂纹尖端应力应变场(包括Ⅰ、Ⅱ、Ⅲ型),并进一步应用Local-Global方法对不同尺寸块壳的应力强度因子进行了计算分析,同时对工程中常用的鼓胀系数进行了计算和分析讨论。计算结果表明,对于a/h较大的情况,经典公式是适用的,若a/h不太大时,经典理论将带来较大误差 ...

Root hair plasticity in cereals under abiotic stress
New Phytologist, EarlyView.An integrative perspective on how to study the regulation of root hair plasticity to increase the resilience of cereals to abiotic stress. Summary Abiotic stress is a constant threat to crop growth and yield in the context of climate change. Root systems that can best adapt their architecture to environmental challenges contribute to enhanced ...

Accountability in Government Use of AI: Citizen Concerns and Preferences
Public Administration, EarlyView.ABSTRACT Government adoption of AI opens the “pandora's box” of accountability, a core aspect of public value. Despite the centrality of governmental AI accountability, citizens' concerns and preferences in holding governments accountable for AI usage remain poorly understood.

Shiyou jixie, 2015 为了研究水网地段管道在双侧沉管过程中受力变形的特性，基于有限元软件建立了管道沉沟模型，对不同深度的沉管过程进行力学模拟；同时根据管道下沟过程的受力变形特点，将模型简化成超静定梁，最终推导出不同深度管道最大应力公式。研究结果表明，在下沟过程中，管道上会出现2个应力峰值，当管道的自由端与沟底接触的瞬间管道的应力最大，管道最大应力位于沟上支点附近管道底部的内壁；管道截面上的应力呈8字形分布，截面顶端和底端出现应力峰值，且底端应力大于顶端；管道下沟可以简化超静定梁模型，应力大小与沉沟深度、管道规格密切相关 ...

Compliance in Regulatory Gray Areas: The Case of the Organic Seed Standard
Policy Studies Journal, EarlyView.ABSTRACT Adaptive regulations, designed to balance flexibility with accountability, can embed provisions that unintentionally leave room for firms to shirk on their responsibilities by exploiting flexibility. We call these provisions “regulatory gray areas,” and ask: how should we understand (non‐)compliance in adaptive regulatory settings?
