Asian Politics &Policy, Volume 15, Issue 3, Page 369-389, July 2023., 2023 Abstract Many documented cases of policy transfer in Asia involve small and medium enterprises as well as public enterprises but little is known about how and why these local private actors participate in transnational policy transfer networks. We propose a relational view of policy transfer to examine how agency is exercised in these kinds of transfer

How does fake news spread? Understanding pathways of disinformation spread through APIs
Policy &Internet, Volume 13, Issue 4, Page 560-585, December 2021., 2021 Abstract What are the pathways for spreading disinformation on social media platforms? This article addresses this question by collecting, categorising, and situating an extensive body of research on how application programming interfaces (APIs) provided by social media platforms facilitate the spread of disinformation.

Key n‐Gram Extractions and Analyses of Different Registers Based on Attention Network
Journal of Applied Mathematics, Volume 2021, Issue 1, 2021., 2021 Key n -gram extraction can be seen as extracting n‐grams which can distinguish different registers. Keyword (as n = 1, 1‐gram is the keyword) extraction models are generally carried out from two aspects, the feature extraction and the model design.

Shuitu Baochi Xuebao, 2022 为了探讨不同微地形下坡面土壤水分的时空分布及其变异规律,以北京土石山区人工林坡面为研究对象,在40 m×50 m坡面共布设30个土壤水分观测点,分10 cm间隔观测,观测深度为50~70 cm。2015年4—10月使用Diviner 2000共监测土壤水分20次。结果表明:(1)坡地土壤水分含量时间变化趋势一致,大体随着降雨波动的变化而变化。(2)土壤水分随坡位变化而变化,水平阶上坡位＜中坡位,缓坡中坡位＜下坡位。(3)坡面土壤水分整体随深度的增加而增加,水土保持工程措施可有效改善土壤水分状况 ...

Dizhen xuebao, 2020 本文采用隐式动力有限单元法研究了不同的边坡角度和边坡高度对地形放大效应的影响，并以位移峰值放大系数为衡量地震动放大效应的标准，计算了不同边坡角度和边坡高度条件下的地震响应，在此基础上对模型关键监测点的输出波形以及位移峰值放大系数的变化趋势进行了分析，获得了不同监测点处的地震动时程曲线，揭示了坡角和坡高对单体边坡地震动放大效应的定量作用规律。数值结果表明，相同高度处坡面监测点的水平向位移峰值放大系数大于坡内监测点的，地形放大效应在水平方向具有趋表效应。由于坡面存在入射波和反射波的叠加 ...

Conservation Biology, Volume 34, Issue 1, Page 194-206, February 2020., 2020 Abstract Stand structure develops with stand age. Old‐growth forests with well‐developed stand structure support many species. However, development rates of stand structure likely vary with climate and topography. We modeled structural development of 4 key stand variables and a composite old‐growth index as functions of climatic and topographic ...

Dizhen xuebao, 2023 地震荷载作用下，断层两侧边坡稳定性一直是研究重点，本文主要探讨动态加载对不同位置坡体产生的地震动效应。首先，建立一个截面大小为500 km×100 km的有限元二维动态铲形断层模型，在地表断层两侧构建对称边坡来模拟滑坡地形。然后加载脉冲震源，通过对震源（深度为14 km）处节点指定加速度的方法，模拟计算地震发生后100 s内地震波传播对距断层分别为1 km，30 km及100 km的不同边坡震动产生的影响。结果显示：边坡震动强度随着震源距的增加而快速衰减，下盘的衰减比上盘更为强烈；距断层相同位置处 ...

The Role of Technology Standards in Strategic Hedging
Asian Politics &Policy, Volume 18, Issue 2, April 2026.ABSTRACT This article argues that technology standards provide Southeast Asian states with a distinct mechanism for hedging amid intensifying US–China technological rivalry. Traditional hedging strategies emphasizing economic engagement without political alignment are increasingly constrained by the weaponization of technological interdependence ...

Review of Policy Research, Volume 43, Issue 2, March 2026.ABSTRACT This study applies the Narrative Policy Framework (NPF) within a non‐democratic context, exploring the role of policy narratives in the implementation of patient‐centred healthcare policy in China. Drawing on a dataset of academic journal articles that reference both “market” and “patient‐centredness,” the research reveals how local ...
