Emotion and the Advocacy Coalition Framework: An Affective Dynamics Perspective

open access: yesPolicy 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.

It Does Matter. A New Framework on the Influence of Policy Evaluation

open access: yesPolicy 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.

行星锥盘无级变速器的传动比和受力分析

open access: yesJixie chuandong, 1990
本文根据相对运动的原理,给整个行星传动加上一个与转臂角速度大小相等而方向相反的角速度,于是转臂可视为静止不动,转化为定轴传动,即转化机构;这样既不改变各构件间的相对运动,也不改变各构件间的受力关系,因此本文在这基础上计算行星锥盘无级变速器的传动比,分析这种变速机在恒功率、恒转矩时各摩擦轮上的作用力,并附有例题。

非线性双折射色散缓变光纤中极化调制不稳定性

open access: yesGuangtongxin yanjiu, 2003
利用光脉冲在光纤中传播时所遵守的相干非线性薛定谔耦合方程,研究了线偏振光在双折射色散缓变光纤中的传输特性.结果表明,线性双折射、非线性效应和色散的相互作用,使光的偏振状态发生变化,产生交叉相位调制(XPM),从而导致相位匹配参量的四波混频.这一过程不仅在反常色散区产生,在正常色散区也能产生,并且当传输距离发生变化时,也随之发生变化.
