Learner‐Focused Strategy Instruction From the Teachers’ and the Learners’ Perspective
International Journal of Applied Linguistics, EarlyView.ABSTRACT Numerous large‐scale quantitative studies have been conducted to yield a macro‐level picture of the effectiveness of strategy instruction. However, little is understood about learners' actual processing of strategy instruction and interaction with the teachers delivering it.

Review of Policy Research, EarlyView.ABSTRACT In the face of increasingly complex environmental challenges, subnational governments play a critical role in implementing climate policies. This study investigates how intergovernmental interactions—specifically formal authority interactions and informal competitive interactions—shape the adoption of climate policies by Chinese provincial ...

Review of Policy Research, Volume 42, Issue 5, Page 1322-1349, September 2025.Abstract Narratives play an essential role in fast‐paced policy making that occurs during crises. The COVID‐19 pandemic brought numerous disruptions of normality, including school closures, which were intensely debated in narratives by many policy actors. Two shutdowns of New York City's public school system affected over 1.1 million students.

The Historical Roots of Energy Consumption: Does Financial Development Matter?
World Affairs, Volume 188, Issue 3, Fall 2025.ABSTRACT The objective of this study is to investigate how statehood experience affects energy consumption through the advancement of finance and its sub‐sectors. By doing so, the study uses the ordinary and two‐stage least squares methods to analyze data from 111 countries spanning from 2000 to 2018.

Guangtongxin yanjiu, 2016 介绍了二阶DRA（分布式拉曼放大器）的结构原理和等效噪声指数,在此基础上,通过实验和理论分析研究了二阶DRA的噪声特性与一阶二阶泵浦注入比例的关系。结果表明,放大器增益基本不变时,二阶泵浦光注入比例越大,等效噪声指数越小;通过适当地调整一阶二阶泵浦功率,可使放大器工作在更小噪声条件下,使整个系统的噪声性能得以提升。

Ultrasound in Obstetrics &Gynecology, Volume 65, Issue 1, Page 85-93, January 2025.ABSTRACT Objective Accurate differentiation between placenta accreta spectrum (PAS) and uterine‐scar dehiscence with underlying non‐adherent placenta is often challenging, even for PAS experts, both prenatally and intraoperatively. We investigated the use of standardized two‐dimensional grayscale ultrasound and Doppler imaging markers in ...

Jianzhu Gangjiegou Jinzhan, 2007 在钢框架二阶弹性分析中,结构整体初始几何缺陷和构件的初始几何缺陷是实际存在的,其影响不可忽略。因此在由单根柱和梁组成的平面子结构二阶弹性理论模型中,引入以上两种几何缺陷,得出了位移与内力的计算公式。利用该理论模型,可以考虑各参数对框架柱二阶效应的影响,并能系统分析框架结构整体几何缺陷与构件几何缺陷对二阶弹性弯矩的影响。
