Abstract

Earthquake emergency response is a complex process, and a large number of tasks are involved in the process of urban earthquake emergency response. To further study the collaborative relationship between organisations in the city-level emergency collaboration network driven by different emergency tasks, this study first constructs a task–organisation relationship framework and explores the collaborative mechanism of organisations driven by tasks. Then, the co-expression analysis was used to analyse the degree of correlation between task-driven emergency organisations. Finally, considering the influence of tasks on the degree of inter-organisational collaboration, this study constructs a task-driven weighted directed emergency organisation collaboration network. Social network analysis was used to reveal the structural attributes of the task-driven organisational collaboration network, the collaborative characteristics among organisations in the network, and the structural positions of organisations in the collaborative network. It is found that the task-driven earthquake emergency collaboration network was relatively loose, and there were small groups with close collaboration in the network. Most organisations in these small groups are in the same task module, and their tasks are similar. Commanders in the task execution process are usually at the core of the network, and these organisations are usually the main coordinators of the overall emergency collaboration and task module networks. These findings can improve our understanding of earthquake emergency organisational collaboration relationships and inspire the optimisation of urban earthquake emergency management.
任务驱动型城市地震应急组织协作关系研究
地震应急响应是一个复杂的过程,城市地震应急响应过程中涉及大量的任务。为进一步研究不同应急任务驱动下城市级应急协作网络中组织间的协作关系,本研究首先构建了任务-组织关系框架,探讨了任务驱动下组织间的协作机制。然后,利用共表分析法分析任务驱动型应急组织之间的关联程度。最后,考虑到任务对组织间协作程度的影响,本研究构建了任务驱动的加权定向应急组织协作网络。利用社会网络分析揭示了任务驱动型组织协作网络的结构属性、网络中组织间的协作特征以及组织在协作网络中的结构地位。研究发现,任务驱动型地震应急协作网络相对松散,网络中存在协作密切的小团体。这些小团体中的大多数组织处于同一任务模块中,其任务相似。任务执行过程中的指挥者通常是网络的核心,这些组织通常是整个应急协作网络和任务模块网络的主要协调者。这些发现可以加深我们对地震应急组织协作关系的理解,并对优化城市地震应急管理有所启发。

期刊介绍: The International Journal of Disaster Risk Reduction (IJDRR) is the journal for researchers, policymakers and practitioners across diverse disciplines: earth sciences and their implications; environmental sciences; engineering; urban studies; geography; and the social sciences. IJDRR publishes fundamental and applied research, critical reviews, policy papers and case studies with a particular focus on multi-disciplinary research that aims to reduce the impact of natural, technological, social and intentional disasters. IJDRR stimulates exchange of ideas and knowledge transfer on disaster research, mitigation, adaptation, prevention and risk reduction at all geographical scales: local, national and international. Key topics:- -multifaceted disaster and cascading disasters -the development of disaster risk reduction strategies and techniques -discussion and development of effective warning and educational systems for risk management at all levels -disasters associated with climate change -vulnerability analysis and vulnerability trends -emerging risks -resilience against disasters. The journal particularly encourages papers that approach risk from a multi-disciplinary perspective.
