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 ...

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,

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‐

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 ...

四川大学学报. 自然科学版, 1992 当一细激光束通过某些具有多畴结构的晶体时,将会出现强的衍射带或其他形状的衍射花样,这些衍射花样是由晶体中准周期性排列的畴结构形成的空间光栅衍射的结果。晶体发生相变时,原畴消失,新畴产生和畴壁运动同时发生,因而使衍射花样和光衍射强度发生明显变化,利用这种变化可用光衍射法研究具有多畴结构的晶体相变,对于一般的透明晶体,当发生相变时,由于晶体结构的变化而产生应力,使晶体的均匀性发生变化,从而使通过晶体的光发生明显的散射,甚至消失,因此利用光散射法能提供某些晶体相变的信息 ...

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.

Rare Metals, Volume 45, Issue 7, July 2026.ABSTRACT The construction of core–shell grains can enhance the coercivity of Nd2Fe14B magnets. However, it is a significant challenge to elucidate the formation of these core–shell grains particularly regarding the spontaneous core–shell structure in Y‐substituted Nd2Fe14B alloys.

Gaoya dianqi, 2017 电力变压器是电网中至关重要的元件,并且是变电站中最昂贵的设备。如果空载时突然把变压器投入电网,由于变压器的非线性,在合闸瞬间会产生很大的励磁涌流,其幅值可达稳态时的几十倍或更高。通常励磁涌流的衰减速度要比短路电流的衰减速度更慢,在上述高幅值的励磁涌流下,很容易引起变压器差动保护装置误动、绕组机械应力增大以及电能质量降低等问题,而真空断路器的选相合闸能很好的解决这个问题。文中在某大功率试验站的6 kV网络试验回路上采用12 kV快速真空开关进行了空载变压器的合闸试验,试验中测量了真空断路器随机合闸 ...
