Basic income trials and the politics of scale: A research agenda
Abstract The growing popularity of basic income has led to extensive trials of the policy in numerous settings across the world. However, analysis of the politics of basic income, and in particular the political dynamics preceding and resulting from trial programs, lags. In response, we propose a research agenda that uses political scale to investigate

到目前为止,已有大量文献介绍了各类绝缘子的人工污秽试验结果,少有文献涉及交直流人工污秽试验电源的特性试验研究。特高压交直流污秽试验电源电压高,电源特性实现难度大,因此需要对电源特性进行试验研究,探索交直流污秽电源的参数特性及其规律。昆明特高压实验室污秽实验室开展了一系列特高压交直流污秽电源的特性试验研究。研究成果一方面为人工污秽试验的理论研究和工程应用提供依据,同时为待建或已建交直流污秽试验电源的特性试验研究提供参考。文中说明了污秽交直流试验电源的工作原理和性能要求 ...

Powerful representation of the poor? German welfare associations' narrative advocacy during COVID‐19
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 ...

ABSTRACT Public appointments shape the top‐level bureaucracy by serving as a gateway for professionals with different profiles, chosen based on different criteria. In general, the literature has been more interested in analyzing appointments based on merit or sponsorship, based on verification of loyalty to the government or technical competence ...

Canine atopic dermatitis (cAD) is a chronic condition requiring life‐long management. Accurate diagnosis can be challenging, with no reliable diagnostic test. This study aimed to generate a simple diagnostic model for cAD. This model is a relevant prototype for an app‐based tool to support general practitioners in the diagnosis of cAD alongside ...
