Powerful representation of the poor? German welfare associations' narrative advocacy during COVID‐19
Policy Studies Journal, EarlyView.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 ...

粪便显微分析和DNA宏条形码技术在野猪食性分析中的应用和比较
野生动物学报, 2022 有蹄类动物食性分析对基础生态学研究乃至大型濒危食肉动物保护与恢复有重要科学价值。食物组成定量化有很多方法,常用的方法有粪便显微分析和DNA宏条形码技术,但各有其优缺点。2014年12月—2016年3月,在珲春、汪清、黄泥河、天桥岭和穆棱5个地区收集了野猪(Sus scrofa)新鲜粪便样品,运用粪便显微分析和DNA宏条形码技术比较研究了冬季野猪食性。仅对比分析了野猪植物性食物,通过粪便显微分析获得的野猪食物组成包含32属植物,比例大于4%的主要食物有木贼属(Equisetum,(22.76±1.87)%)

Nonlinear Alfven waves in a collision-free plasma [PDF]
, 1980 Hydromagnetic waves propagating in a collision-free plasma are investigeted on the basis of hydrodynamical transport equations. Under the consideration of the electron and ion temperatures, we derived the basic equations which describe the one ...

Policy Studies Journal, EarlyView.ABSTRACT Why did Australia go from the White Australia Policy, which excluded non‐whites, to institutionalizing multiculturalism policy in the 1970s? This question defies traditional political ideologies of the major political parties, which had long supported the White Australia Policy. This article is a rare empirical demonstration of the Five‐Thread

Jianzhu Gangjiegou Jinzhan, 2017 建立了双钢板-混凝土组合剪力墙的精细化有限元模型,在模型中采用了基于断裂能和单元特征长度的混凝土应力-应变关系,有限元分析获得的墙体侧向力-侧向总变形关系、弯矩-曲率关系与已有的他人试验结果吻合较好。对曲率二次积分求得弯曲变形,将总变形分解为弯曲变形和剪切变形两部分。结果表明,破坏模式为弯曲控制的双钢板-混凝土组合剪力墙在加载过程中弯曲刚度和剪切刚度均有退化,其剪切变形不宜采用弹性方法计算,且剪切变形占总变形的比例在变形过程中基本上为常数。对剪切变形在总变形中所占的比例进行了参数分析,结果表明 ...

Policy Studies Journal, EarlyView.ABSTRACT Despite extensive research on policy diffusion, the ways in which policy attention influences this process remain underexplored. This study addressed this gap by distinguishing between three types of policy attention—political speeches, policy issuance and field visits—and investigating their differential impacts when delivered by central and ...

Policy Studies Journal, EarlyView.ABSTRACT Based on the Punctuated Equilibrium Theory (PET) and implementation research, this study proposes an extended conceptualization of policy punctuation that enables researchers to systematically include policy implementation as part of a punctuation. The key mechanisms underlying the PET, i.e., policy image and venue, information processing, and

Emotion and the Advocacy Coalition Framework: An Affective Dynamics Perspective
Policy Studies Journal, EarlyView.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.
