International media coverage promotes donations to a climate disaster
The Australian bushfires in 2019–20 triggered massive amounts of charitable giving from the community. This study applied agenda‐setting theory to examine if and how disaster news coverage influenced public donations in response to the crisis. A survey of 949 Australians found that people perceived news coverage of the event to be a strong influence on

Psychological First Aid (PFA) is widely used in the early phases of disaster recovery, despite limited empirical evidence supporting its application. PFA aims to reduce distress and encourage adaptive coping and is grounded in five principles: the promotion of hope, self‐ and collective efficacy, social connectedness, safety, and calm.

How Many Floods Have Occurred in China in the Past Decade? A Perspective From Social Media
Abstract Global climate change has led to frequent and widespread flood disasters in China. Traditional flood disaster investigations mainly focus on major flood events, and small‐scale flood events are often overlooked. This study utilized the Sina Weibo social media platform to detect flood events in 370 cities in China from 2012 to 2023.

Abstract Illegal collecting of wild Venus flytraps (Dionaea muscipula) for the horticultural trade represents a persistent threat to populations of the species across their endemic range in the coastal plain of North and South Carolina (United States). Although wild collecting of Venus flytraps is not a novel threat, there has been very little research

Abstract Disaster‐specific Facebook groups (DSFGs) are Facebook groups devoted to a specific disaster or set of disasters. I argue DSFGs offer opportunities for disaster response and resilience organizing that can mitigate the limitations of institutionalized disaster response and illustrate the benefits and detriments of the use of DSFGs by survivors ...

Experimentally testing animal responses to prescribed fire size and severity
Abstract Deserts are often highly biodiverse and provide important habitats for many threatened species. Fire is a dominant disturbance in deserts, and prescribed burning is increasingly being used by conservation managers and Indigenous peoples to mitigate the damaging effects of climate change, invasive plants, and land‐use change. The size, severity,

Local populations are aware of the decline and disappearance of Detarium species in their habitats, attributing this trend to excessive human exploitation and the effects of climate change. Thus, Detarium plant resources may face challenges in forests with different levels of protection status due to habitat fragmentation and the effects of climate ...

现行《建筑钢结构防火技术规范》(GB 51249—2017)未给出火灾下钢结构的局部稳定设计方法,为了获得轴心受压焊接H形高强Q690钢柱高温下的局部稳定性能,考虑钢材高温下力学性能退化、截面高温下焊接残余应力降低及初始几何缺陷,采用ABAQUS软件建立经试验验证的高温局部稳定分析有限元模型,得到焊接H形高强Q690钢柱在不同温度下的局部屈曲应力和极限应力。研究表明:当温度低于550℃时,钢柱在高温下和常温下屈曲应力具有相同的变化趋势;高温下的残余应力值和初始几何缺陷对屈曲应力有较大的影响 ...
