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 ...

Policy Studies Journal, EarlyView.ABSTRACT As the Narrative Policy Framework (NPF) begins to unpack issues of power and narratives, the main focus has been on power‐over and domination rather than more transformative notions of power‐to and empowerment. This article draws on insights from gender and policy studies and suggests that the NPF benefits from adopting a multifaceted notion ...

Devouring the Invaders: The Racial‐Ecological Politics of the Chinese Crayfish Trade in Kenya
American Anthropologist, Volume 128, Issue 1, Page 183-194, March 2026.ABSTRACT This article examines entanglements of ecology, race, and foodways at Lake Naivasha in Kenya. Nonnative Louisiana red swamp crayfish (Procambarus clarkii), first introduced to Kenya in the 1960s, were once viewed as invasive but are now sought after as a delicacy among Kenya's Chinese community.

Dizhen xuebao, 2021 为了及时、准确、可靠地发出地震预警信息，本文提出了一种基于贝叶斯理论的地震P波双参数预警方法。选取中国地震台网中心记录的四川地区的355条地震数据，统计P波触发后前3 s的P波平均周期τc和位移幅值Pd，结合贝叶斯理论建立震级和峰值加速度的预测模型，并以震级M4.5和峰值加速度为120 cm/s2为预警阈值，建立了地震危害性判别模型。与传统拟合方法进行对比仿真分析，并以汶川MS8.0地震为震例，进行地震危害性判别实验与分析。实验结果表明：本文提出的基于贝叶斯理论的地震 P ...

On the Judicial Determination for the Crime of Abuse of Authority [PDF]
, 2016 内容摘要 滥用职权罪是渎职犯罪的一个重要罪名。近年来，在依法治国的引领下，加强国家公职人员的廉政建设，因此，通过法律手段惩治贪污腐败和滥用职权极为必要。 滥用职权罪的认定既是刑法理论问题，又是司法实践问题。我国现行滥用职权罪的司法认定标准是否能够涵盖滥用职权罪的形态和范围呢？我国滥用职权罪司法认定实践中还有哪些疑难问题值得进一步探讨，是本文研究的主要内容。 本文通过对滥用职权罪的主观方面、因果关系、危害后果三个方面进行细致的分析，通过对我国现行的司法认定标准与外国的司法认定标准进行比较 ...
