A Narrative Walks Into a Forum: Bridging the Narrative Policy and Ecology of Games Frameworks

open access: yesPolicy Studies Journal, Volume 54, Issue 3, August 2026.
ABSTRACT Policy process research has expanded rapidly, yet many frameworks still develop in silos, limiting dialogue and leaving complementary mechanisms underused. In an effort to bridge these silos, we bring together two influential frameworks that have largely developed in parallel: the Narrative Policy Framework (NPF) and the Ecology of Games ...

民主理论和理论上的物理 [PDF]

open access: yes, 2011
本文章辩论,在 Simmelian (齐美尔联) 的线之间,民主理论即可能产生实际和普遍理论, 像类似理论物理学的发展。这篇文章背后的推理是要表明,”基层民主“的理论比较于爱因斯坦的狭义相对论可能是实在- 特别关于对称,统一,简单和实用的参数。\ud \ud 这些参数不仅适应当前的知识, 也是作为物理理论的成分之一, 但也产生对测试(应用程序)的路径。一旦“基本的民主“的理论满足这些参数,它可以解决民主定义的争论。首先, 将讨论“基层民主“的理论是什么及为什么它不同于以往的作品;第二,通过解释选择的参数(

Assessing D‐Squame as a Minimally Invasive Technique to Evaluate the Cutaneous Immune Response mRNA in a Dog Model of Canine Atopic Dermatitis

open access: yesVeterinary Dermatology, Volume 37, Issue 3, Page 353-364, June 2026.
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 ...
