Powerful representation of the poor? German welfare associations' narrative advocacy during COVID‐19
Policy Studies Journal, Volume 54, Issue 3, August 2026.Abstract The COVID‐19 pandemic sparked unprecedented experimentation in the German social assistance system, leading to changes previously considered impracticable by policymakers. This included a sanctions moratorium, easier access to benefits, and temporary cash transfers, all of which were advocated by welfare associations—key organized interests ...

Gaoya dianqi, 2018 为实现电气设备局部放电模式的准确识别,提出了一种基于时频特征核熵成分分析的局部放电模式识别方法。首先采用S变换理论对局部放电脉冲信号进行时频特征分析,针对S变换分析结果维数庞大但冗余信息较多而不便于模式识别的缺点,基于核熵成分分析方法对S变换结果进行压缩降维处理,得到了局部放电模式识别时频特征向量,同时结合随机森林分类器实现了局部放电类型的准确识别。搭建了尖端放电、沿面放电、气泡放电、悬浮放电等典型变压器绝缘缺陷模型并采集了局部放电信号,分别采用文中方法、PCA方法及KPCA方法进行了局放模式识别实验 ...

Policy Studies Journal, Volume 54, Issue 3, August 2026.ABSTRACT What are the conditions under which business corporations expand their institutional power? This paper argues that institutional power is affected by the architecture of the “acquisition regime”—the set of formal (and informal) rules that govern how states purchase public services.

Gaoya dianqi, 2008 为了提高变压器故障诊断正判率,提出了一种邻域粒子群算法优化BP神经网络的电力变压器油中气体分析（DGA）方法,即通过相关统计分析和数据的预处理,选择变压器油中典型气体作为神经网络的输入,然后利用训练好的邻域粒子群算法优化后的神经网络进行变压器故障类型诊断。试验结果表明,该类方法具有很好的分类效果,较好地解决了变压器放电和过热共存时故障的难分辨问题,对故障类型的正判率较高。

Emotion and the Advocacy Coalition Framework: An Affective Dynamics Perspective
Policy Studies Journal, Volume 54, Issue 3, August 2026.ABSTRACT Despite extensive evidence that emotion and cognition are deeply intertwined, the Advocacy Coalition Framework (ACF) lacks an analytically independent emotional mechanism in its causal architecture—an omission that may be particularly consequential in policy subsystems structured around morally charged, identity‐laden policy disputes.

Rhetorical Diffusion and Policy Latency: Tracing AIPAC Influence in US–Iran Relations (2010–2026)
Policy Studies Journal, Volume 54, Issue 3, August 2026.ABSTRACT How do domestic interest groups shape the transition from diplomatic agreements to kinetic warfare? This research article addresses the methodological stagnation in foreign policy analysis by introducing a computational text‐as‐data pipeline to systematically quantify lobbying influence.

Gaoya dianqi, 2008 笔者应用气相色谱分析技术中的成分超标法I、EC三比值法以及平衡判据法成功地判断出一台主变压器B相内部所存在的突发性电弧放电故障。变压器停运后吊罩检查结果与气相色谱分析诊断结论相吻合,验证了气相色谱分析技术诸方法的正确性及有效性,为大型变压器的运行和异常判断提供了经验。

Policy Studies Journal, Volume 54, Issue 3, August 2026.ABSTRACT This study introduces a dual‐layer protocol for diagnosing how formal institutional designs are implemented in practice in complex governance systems. The protocol builds two linked process maps; one for the formal rules and procedures (rules‐in‐form) and one for the routines actors actually follow in practice (rules‐in‐use).

Gaoya dianqi, 2007 通过对一种注入式混合有源滤波器建立数学模型,结合传统滑模变结构控制算法快速性好和递推积分PI控制算法无稳态误差的优点,提出一种新的复合变结构控制算法作为有源滤波器的电流控制方法。通过仿真,从算法的跟踪速度和控制精度两个方面,将新的复合变结构控制算法与传统滑模变结构控制算法以及单一的递推积分PI控制算法进行了比较分析。实验结果也证明了该算法的正确性和有效性。

It Does Matter. A New Framework on the Influence of Policy Evaluation
Policy Studies Journal, Volume 54, Issue 3, August 2026.ABSTRACT Governments worldwide have invested heavily in policy evaluation, providing many policymakers with a steady stream of evidence into the effectiveness, efficiency, or relevance of policies. Yet, despite these investments, systematic knowledge about the actual influence of policy evaluations remains surprisingly limited.
