On a branching route: The spectrum of path dependence in policy research

open access: yesReview of Policy Research, EarlyView.
Abstract This article describes the evolution of discussions around the concept of path dependence, which has established itself as an explanatory framework in various academic disciplines, including policy research. It outlines the diversity of conceptual ideas, presents efforts at specification that have expanded the range of possible interpretations

Continuities in policy change: The case of squatter housing redevelopment strategies in Türkiye

open access: yesReview of Policy Research, EarlyView.
Abstract The introduction of the neoliberal agenda in the 1980s marked a milestone for urban studies, where the neoliberal framework became widely accepted as both given and explanatory for understanding urban phenomena. This tendency often obscured policy continuities rooted in the historical and social contexts of specific geographies.

载脂蛋白A1和载脂蛋白B100在冠脉病变进展中的作用

open access: yesZhongshan Daxue xuebao. Yixue kexue ban, 2017
【目的】通过回顾性资料,分析载脂蛋白(APO)A1、B100对冠状动脉病变进展的影响及预测作用。【方法】入 选2010年6月至2015年10月于中山大学附属第三医院行冠状动脉造影或冠脉CTA检查,并在间隔≥6个月后复查冠脉情况 的患者(245例),分为冠脉病变非进展组(114例)、进展组(131例)。比较两组间临床资料及生化指标差异,并通过回归分 析,了解APOA1、APOB100与冠脉病变进展的关系。【结果】两组比较,冠脉病变非进展组基线APOA1水平(1.33 ± 0.29 vs 1.24 ±

Coalitions and Characters: Tracing the Maturity of Sweden's Preventing and Countering Violent Extremism Policies

open access: yesReview of Policy Research, EarlyView.
ABSTRACT We trace the shift from a nascent to a mature policy subsystem by examining a hitherto overlooked aspect in policy process scholarship: the relationship between advocacy coalition beliefs and the narratives they express over time. The empirical focus of this case study is Sweden's Preventing and Countering Violent Extremism (P/CVE) policies ...

非线性渐增光纤中超短脉冲自相似演化的研究

open access: yesGuangtongxin yanjiu, 2011
为进一步研究非线性渐增光纤中超短脉冲自相似演化的特性,利用数值仿真的方法分析了入射脉冲能量、脉冲宽度和类增益系数3个因素对输入脉冲自相似演变的影响。结果显示:入射脉冲能量和类增益系数对自相似演变的影响较为显著,在增大入射脉冲能量或类增益系数的情况下均可加速自相似演化的速度,即缩小演化所需的特征距离;而脉冲宽度对自相似演化的速度影响则十分微弱。
