Coalition Opportunity Structures and Advocacy Coordination in Consensus and Majoritarian Democracies
Policy Studies Journal, EarlyView.ABSTRACT Research on advocacy coalitions suggests that belief homophily—the tendency of actors to coordinate based on shared policy beliefs—drives coalition formation. However, coalition opportunity structures, which are shaped by institutional contexts, may influence the extent to which belief homophily matters.

一种快速高鲁棒性变压器铁心Jiles-Atherton磁滞模型参数辨识方法
Gaoya dianqi, 2020 Jiles-Atherton（J-A）模型是变压器剩磁与励磁涌流计算的重要方法,但在使用中存在着参数辨识的难题。文中从参数辨识的公式法、遗传算法、Nelder-Mead（NM）单纯形算法原理及各自特点出发,提出一种综合运用公式法和两种优化算法对实测磁化曲线进行参数辨识的方法。算例分析结果表明,该方法对于经典JA模型参数识别具有较高的精度,在误差影响下体现出良好的鲁棒性,是一种快速、有效的J-A模型参数辨识方法。

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 ...

Veterinary Dermatology, EarlyView.Background: Canine atopic dermatitis (cAD) is a common, chronic skin condition characterised by epidermal barrier dysfunction, immune dysregulation and cutaneous dysbiosis. While “emollient plus” formulations are widely used in human atopic dermatitis, their role in cAD remains underexplored. Hypothesis/Objectives: To evaluate the clinical efficacy and

Dianci bileiqi, 2019 为了解双端接地时影响二次电缆芯线-屏蔽层电位差的各参数作用大小,及其各参数与芯线-屏蔽层电位差之间的线性程度,通过Matlab编程对电缆芯线-屏蔽层电位差进行计算分析,将二次电缆芯线-屏蔽层电位差作为目标函数,在函数定义区间内进行各个参数灵敏度分析。计算表明:接地网导体间距参数灵敏度较大,对芯线-屏蔽层电位差的影响作用最强,两者变化情况呈非线性关系,是优化设计的主要考虑因素;地网边长、电缆长度的参数灵敏度系数相对较小,可以在合理的范围内改变这两个参数进行优化,但效果不大;土壤电阻率参数灵敏度较小,芯线 ...

Veterinary Dermatology, EarlyView.ABSTRACT Background Canine atopic dermatitis (cAD) is a multifactorial, inherited skin disease, estimated to affect ≤ 15% of dogs. Studies of skin messenger mRNA in cAD currently use invasive methods, including blood sampling and biopsy collection, whilst advances in human atopic dermatitis study methodology have demonstrated reliable use of minimally ...

How New Issues Become Polarized: Partisan Triggers and Subsystem Shopping in Early AI Policymaking
Policy &Internet, Volume 18, Issue 1, March 2026.ABSTRACT Early AI policymaking in the United States appeared bipartisan, but subsequent developments raise the question of whether AI policy will become more polarized over time. To examine how partisanship takes root around novel policy issues, we perform a mixed‐methods study, analyzing survey data from 129 state legislators in 44 states and ...
