Disasters, Volume 47, Issue 3, Page 806-829, July 2023., 2023 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.

Journal of Traumatic Stress, Volume 36, Issue 2, Page 465-473, April 2023., 2023 Abstract The 2014 Hazelwood coal mine fire in the Latrobe Valley, Australia, distributed toxic smoke into surrounding communities over 45 days. This study investigated risk and protective factors associated with four trajectories of posttraumatic distress (resilient, recovery, delayed‐onset, chronic) among exposed adults.

Urban Architecture and Development, 2023 为了满足城市居民居住的需要，建筑甚至是超建筑逐渐增多。虽然建筑的出现，解决了城市化进程中的一些难题。但是，建筑的增加，也带来了一些不可避免的问题，比如消防安全问题。建筑发生火灾安全事故的概率较高，一旦发生火灾，往往很难在短时间内扑灭。因此，如何更好地预防和解决建筑消防火灾问题，是新时期我国各地城市管理部门的重要课题。文章旨在研究建筑消防工作中存在的问题，并提出相应的解决对策，以供各地区在建筑消防预防及灭火救援方面提供参考。

Conservation Biology, Volume 37, Issue 2, April 2023., 2023 Abstract Monitoring is critical to assess management effectiveness, but broadscale systematic assessments of monitoring to evaluate and improve recovery efforts are lacking. We compiled 1808 time series from 71 threatened and near‐threatened terrestrial and volant mammal species and subspecies in Australia (48% of all threatened mammal taxa) to compare

Jianzhu Gangjiegou Jinzhan, 2023 螺纹锚固单边螺栓锚固于带螺纹的螺栓孔。螺纹锚固单边螺栓无需螺母，能够实现单侧安装，因此非常适用于闭口截面钢构件的连接。了解不同结构在火灾后的受力性能具有重要的工程意义，能够为受火结构的鉴定和修复提供依据。通过试验研究了螺纹锚固单边螺栓连接节点在火灾后的性能，试验中采用全过程的加载方式，模拟了火灾从开始到结束的过程，并考虑了火灾发生时节点承受的荷载大小和火灾温度对于其火灾后残余力学性能的影响。试验结果表明，螺纹锚固单边螺栓连接节点共有两种破坏模式，分别为钢管壁屈服破坏和T形板翼缘屈服伴随螺栓破坏 ...

Jianzhu Gangjiegou Jinzhan, 2023 通过试验，对新型螺纹锚固螺栓连接T形节点在高温后的拉伸性能进行了研究。此类螺栓直接锚固于带螺纹的螺栓孔内，无需螺帽，非常适合用于闭口截面钢构件的连接。试验采用全周期的加载方式，以考虑火灾高温和荷载大小对节点在火灾后受力性能的影响。对于节点板厚和螺栓直径等参数对节点受灾后受力性能的影响也进行了分析。螺栓孔厚度和螺栓直径共同决定了节点的破坏模式，且对节点的在火灾后的承载力有一定的影响。火灾温度和荷载大小影响了节点的破坏阶段，但是并不改变节点的破坏模式。对于火灾中未发生破坏的节点 ...
