The Inclusion Trade‐Off: Comparing the Design and Functionality of Collaborative Governance Forums
Policy Studies Journal, EarlyView.ABSTRACT Environmental challenges require collaboration across jurisdictions, often through forums or intermediary spaces for repeated interaction. A persistent forum design question concerns inclusion criteria, or which actors should be included.

Unpacking Welfare Deservingness Theory: Evidence From the Perceived Deservingness of Gig Workers
Policy Studies Journal, EarlyView.ABSTRACT The theory of welfare deservingness provides valuable insights into the social legitimacy of welfare programs and the principles underlying policy design. In examining the question of who deserves what and why, established deservingness criteria emphasize that individuals demonstrating motivation to work (“reciprocity”) are typically perceived

Dizhen xuebao, 2019 鉴于传统的地震动强度表征参数（IM）不能有效地反映速度脉冲型地震动的破坏特征，需要研究能够在全周期段内表征速度脉冲型地震动强度的参数。本文首先从NGA-West2强震数据库中选取了236条速度脉冲记录，分析了42种地震动参数之间的相似性和相关性，初步给出了速度脉冲型地震动强度的表征参数；其次，利用单自由度体系动力时程分析方法，研究了不同延性μ条件下速度脉冲型地震动强度表征参数与最大非线性位移um之间的相关性系数随周期T的变化特征 ...

The Essence of Crisis Decision‐Making: Saving Ravenna During the 2023 Floods
Risk, Hazards &Crisis in Public Policy, Volume 17, Issue 2, June 2026.ABSTRACT This article explores decision‐making processes in crisis situations by proposing an interpretive framework grounded in multiple criteria of rationality. Crises, characterized by uncertainty, urgency, and ethical dilemmas, require critical choices that go beyond standard procedures.

Veterinary 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 ...
