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, 2010 断路器在随机关合空载变压器时会产生幅值、频率很高的励磁涌流,这种操作暂态可能导致微机继保装置误动作,降低用户电能质量和系统可靠性。根据空载变压器涌流产生的机理,采用选相关合技术消除变压器励磁涌流,研究了铁心剩磁和最佳关合相位关系;分析了断路器截流和暂态恢复电压对铁心剩磁影响,并给出了剩磁测量方法。在空载变压器选相关合原理基础上,采用ATP-EMTP软件建立空载变压器关合模型,对暂态过程进行了仿真。仿真结果表明,选相关合技术能有效消除空载变压器合闸时产生的励磁涌流,为空载变压器选相关合提供了理论基础。

Policy Studies Journal, Volume 54, Issue 3, August 2026.Abstract We examine whether and how public participation in policymaking contributes towards fostering stakeholder support for policy proposals formulated in the bureaucratic arena. We explain how key markers of procedural fairness describing both the participation process and policymakers' presentations of it during the decision justification stage co‐

, 2010 采用双离子束溅射氧化钒薄膜附加热处理的方式制备了纳米二氧化钒薄膜.在热驱动方式下,分别利用四探针测试技术和傅里叶变换红外光谱技术对纳米二氧化钒薄膜的电学与光学半导体-金属相变特性进行了测试与分析.实验结果表明,电学相变特性与光学相变特性之间存在明显的偏差,电学相变温度为63℃,高于光学相变温度,60℃;电学相变持续的温度宽度较光学相变持续温度宽度宽;在红外光波段,随着波长的增加,纳米二氧化钒薄膜的光学相变温度逐渐增大,由半导体相向金属相转变的初始温度逐渐升高,相变持续的温度宽度变窄.在红外光波段 ...

Blocking the Poor: Status Quo Bias in Policy Congruence
Policy Studies Journal, Volume 54, Issue 3, August 2026.ABSTRACT Research on unequal responsiveness has shown that policies tend to align more closely with the preferences of high‐income citizens than low‐income citizens. Using comparative data on opinions and policies, we suggest that this inequality primarily results from status quo bias; asymmetric blocking power drives unequal congruence rather than ...

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.

Zhongguo shiyan zhenduanxue, 2010 目的探讨大肠肿瘤p53和ki-ras基因协同突变的临床意义。方法采用免疫组化和PCR-SSCP方法,检测58例大肠肿瘤患者的良性病变、良性病变转为恶变、原发腺癌组织的p53基因、ki-ras基因的表达和突变情况。结果良性病变组与恶变组间的p53基因和Ki-ras基因的表达有显著差异,良性病变组与原发腺癌组的Ki-ras基因表达差异显著;良性病变组的p53基因与Ki-ras基因的表达呈负相关,而恶变组和原发腺癌组呈正相关。p53基因和ki-ras基因两种基因突变率无显著差异,而协同突变与淋巴结转移密切相关,
