Behavioral interventions to reduce demand for threatened freshwater turtles as pets
Abstract Growing demand for freshwater turtles as pets has fueled illegal trade and accelerated wild population declines, underscoring the need for theory‐based demand‐reduction interventions. We conducted a three‐part randomized controlled trial with active turtle keepers (n = 1800) in China to test conservation‐ and legality‐framed messages by ...

为将基于能量的抗震设计方法应用到多自由度结构的抗震设计中,选用20条远场地震波和15条近场地震波,对不同层数的V形偏心支撑钢框架滞回能需求层间分布规律进行了研究,对比分析了远、近场地震下结构滞回能需求分布的不同,给出了滞回能需求层间分布系数的简化计算公式。研究表明,V形偏心支撑钢框架主要依靠耗能梁段发生剪切变形耗散地震能量;近场地震会加大结构底部响应及滞回能需求。

Unveiling Entropy‐Driven Hard‐Tough Synergy Mechanisms in High‐Entropy Carbonitride Ceramics
ABSTRACT High‐entropy ceramics manifested promise for extreme environments, yet their phase stability and mechanical synergy mechanisms remain elusive. Herein, entropy‐difference carbonitrides, including (TaTiV)CN, (TaTiVNb)CN, and (TaTiVNbHf)CN, were designed and consolidated via spark plasma sintering.

Concurrent Crises and Non‐State Service Provision
ABSTRACT Concurrent crises represent a significant challenge for disaster and public health governance. Activated in response to one threat, governing institutions may be distracted or stretched thin during an emergent crisis. In such crises, governments and communities rely heavily on non‐state service providers such as non‐profit organizations and ...
