Abstract
Purpose
The purpose of this paper is to test the invulnerability of the guarantee network at the equilibrium point.
Design/methodology/approach
This paper introduces a tractable guarantee network model that captures the invulnerability of the network in terms of cascade-based attack. Furthermore, the equilibrium points are introduced for banks to determine loan origination.
Findings
The proposed approach not only develops equilibrium analysis as an extended perspective in the guarantee network, but also applies cascading failure method to construct the guarantee network. The equilibrium points are examined by simulating experiment. The invulnerability of the guarantee network is quantified by the survival of firms in the simulating progress.
Research limitations/implications
There is less study in equilibrium analysis of the guarantee network. Additionally, cascading failure model is expressed in the presented approach. Moreover, agent-based model can be extended in generating the guarantee network in the future study.
Originality/value
The approach of this paper presents a framework to analyze the equilibrium of the guarantee network. For this, the systemic risk of the whole guarantee network and each node's contribution are measured to predict the probability of default on cascading failure. Focusing on cascade failure process based on equilibrium point, the invulnerability of the guarantee network can be quantified.

Abstract
Purpose
The purpose of this paper is to present the results of a pilot study involving high school teachers in natural sciences. The aim was to foster critical thinking about cascading hazards via the use of reasoned imagination. Cascading phenomena can lead to extreme catastrophes and are thus a challenge for disaster prevention and management.
Design/methodology/approach
Following a presentation listing some known cascading phenomena, the participants completed a questionnaire consisting of a blank hazard correlation matrix (HCM) and some open-ended questions. The HCM qualitatively described possible interactions between 16 different perils selected from a large spectrum of natural, technological and socio-economic hazards.
Findings
Most participants were able to describe cascading phenomena within the HCM by reducing them into sets of one-to-one interactions. Based on their experience and imagination, the participants foresaw additional interactions that were not discussed, never observed but are scientifically plausible. The majority of the respondents reported that they learnt something new and wanted to learn more about cascading hazards.
Originality/value
The HCM is especially effective in translating complex hazard scenarios into basic interactions and vice versa. Being imaginative (here via the use of reasoned imagination) and accessible, the HCM could be used as basis for transformative learning in the education of the public and of practitioners on the role of cascading hazards in catastrophes.

Abstract
Purpose
The purpose of this paper is to explain the significance of cascading crises for translators and interpreters, and how their work may be affected by such events. It provides a theoretical basis for analysis and field practice.
Design/methodology/approach
The authors define cascades and explain how they influence the development of preparedness, mitigation and response. The authors identify key drivers of cascading crises and discuss how they challenge conventional approaches to emergency management. The authors discuss ways in which use of language could be a key factor in crisis escalation. The authors define priorities and operational challenges of cascading crises for translators and interpreters. In terms of methodology, this paper develops a conceptual framework that can be used for future enquiry and case history analysis.
Findings
The authors provide a qualitative description and synthesis of the key instructions to be used in the field. The authors offer a short list of key questions that can be referred to by linguists and scholars. The authors identify situations in which translation and interpretation are important ingredients in the success of emergency preparedness and response efforts. These include multilingual populations, migrant crises, international humanitarian deployment and emergency communication during infrastructure failures.
Research limitations/implications
This work has academic value for the process of understanding cascades and practical relevance in terms of how to deal with them.
Practical implications
Translators and interpreters need to understand cascading crises in order to be prepared for the challenges that such events will present.
Social implications
Society has become more complex and interconnected, with non-linear cascading escalation of secondary emergencies. Emergency planners and responders need to address this in new ways. Effective communication and information strategies are essential to the mitigation of cascading disaster risk.
Originality/value
The study of cascading crises from a socio-economic point of view is relatively new, but it is important because society is increasingly dependent on networks that can propagate failure of information supply.

Abstract
Purpose
The purpose of this paper is to concentrate on the place of cyber security risk in the framework of global commitments adopted in 2015 to reduce disaster risks in an all-hazards approach. It explores the correlations between traditional risks associated with critical infrastructures – as understood by the Sendai framework – cyber security risks and the cascading effects characteristic of today’s complex and interrelated shocks and stresses. It takes a step further, expanding the focus of traditionally understood technological risks to explore cyber security risks, at the heart of our societies’ digital transformations,and showcase opportunities from the European context.
Design/methodology/approach
By reviewing existing literature on cyber security, disaster resilience and cascading disasters, this paper highlights current challenges and good practices undertaken by various governments.
Findings
Understanding disaster risks is a precondition to improving the mitigation of impacts of existing risks and preventing new risks. Effective risk reduction relies on a solid understanding of losses resulting from events to inform future actions, and on the assessment of risks relying on a robust evidence base and state-of-the-art scientific capacity to model and simulate potential hazards. In this context, embedding cyber security risks, and the complexity of cascading impacts in improving the understanding of disaster risks, calls for appropriate methods and tools allowing for a multi-risk and holistic focus to the assessment of risks and the planning of risk management capacities that follow.
Research limitations/implications
Globally and in Europe, focus on interconnected risk and their impacts is steadily increasing. Risk assessments are still conservative; incorporation of cyber resilience into national and local level DRR plans is yet not visible.
Originality/value
Existing research is restricted to cyber security and disaster resilience, as separated subjects. This paper, for the first time, brings together the interconnection between the two topic options to address them.

Abstract
Purpose
The concept of multi-purpose cyclone shelters has been found effective in saving various lives during past cyclones. The recent cyclone Amphan, which hit the Indian states of Odisha and West Bengal in the middle of pandemic COVID-19 has posed severe issues related to cyclone shelter management in the rural areas. The purpose of this paper is to investigate the case of Odisha in a pandemic and draw some key lessons of cyclone shelter management, which can be useful for future cascading risks in other parts of the country and the region.
Design/methodology/approach
Cyclone shelters are critical infrastructures in the management of cyclones, associated hazards and saving crucial lives. The effective management of shelters during emergencies is dependent on the existing institutional mechanism, local stakeholders and their understanding of the key functions of the emergency shelters. This paper reviews the key challenges through literature, reports and direct interviews of field professionals and practitioners.
Findings
In normal times, cyclone shelters are used as schools and their management lies with the local communities and/or elected bodies. Some of the key emerging issues include: the convincing population at risk for evacuation with proper care, existing emergency shelters being repurposed as COVID-19 facilities, need for hygiene and safety material, special arrangement and segregation of population at higher risk of COVID-19 and large destruction of social infrastructures.
Originality/value
During cascading disasters, adaptive governance becomes important. With the study of cyclones during the pandemic period, the paper draws key decision-making and governance points of cyclone shelter management. This case analysis can be useful to other similar situations during the prolonged pandemic time.

Abstract
Purpose
Businesses are increasingly vulnerable and exposed to physical climate change risks, which can cascade through local, national and international supply chains. Currently, few methodologies can capture how physical risks impact businesses via the supply chains, yet outside the business literature, methodologies such as sustainability assessments can assess cascading impacts.
Design/methodology/approach
Adopting a scoping review framework by Arksey and O'Malley (2005) and the PRISMA extension for scoping reviews (PRISMA-ScR), this paper reviews 27 articles that assess climate risk in supply chains.
Findings
The literature on supply chain risks of climate change using quantitative techniques is limited. Our review confirms that no research adopts sustainability assessment methods to assess climate risk at a business-level.
Originality/value
Alongside the need to quantify physical risks to businesses is the growing awareness that climate change impacts traverse global supply chains. We review the state of the literature on methodological approaches and identify the opportunities for researchers to use sustainability assessment methods to assess climate risk in the supply chains of an individual business.

Abstract
Purpose
The earth is facing challenges to work for the survival of human life during domino effect disasters. The emergency resource storage locations should be selected considering the probability of domino effect disasters. The first purpose of this study is to select the storage locations where domino effect probability is less. And second, facility development cost and transportation costs and costs for unutilized capacity have been optimized.
Design/methodology/approach
The work is a multiobjective optimization problem and solved with weighted sum approach. At first, the probabilities of domino effect due to natural disasters are calculated based on the earthquake zones. Then with that result along with other necessary data, the location to set up storage facilities and the quantities of resources that need to be transported has been determined.
Findings
The work targeted a country, Bangladesh for example. The authors have noticed that Bangladesh is currently storing relief items at warehouse which is under the domino effect prone region. The authors are proposing to avoid this location and identified the optimized cost for setting up the facilities. In this work, the authors pointed out which location has high probability of domino effect and after avoiding this location whether cost can be optimized, and the result demonstrated that this decision can be economical.
Originality/value
Disaster response authorities should try to take necessary proactive steps during cascading disasters. The novelty of this work is determining the locations to select storage facilities if the authors consider the probability of the domino effect. Then a facility location optimization model has been developed to minimize the costs. This paper can support policymakers to assess the strategies for selecting the location of emergency resource facilities.

Abstract
Purpose
Online knowledge communities have emerged as crucial places for knowledge and risk management in the face of systemic risks. The vitality of online knowledge communities requires users’ active engagement. This research paper aims to explore how text complex level and text analytic level as effective risk knowledge design leverages encourage users’ engagement under different “riskification” levels.
Design/methodology/approach
This paper performs linguistic analysis on 210 TED talk transcripts and 38,377 comments from 2002 to 2018. The authors construct the variable of text complex level and conduct ordinary least squares regressions to test the relationships among text complex level, text analytic level and user engagement under different levels of “riskification” in the online knowledge community.
Findings
High text complex level decreases engagement, while high text analytic level increases engagement. A high level of “riskification” exaggerates the negative effect of text complex level but diminishes the positive effect of the text analytic level.
Originality/value
This research advances knowledge management by highlighting users’ engagement and responding to shared risk knowledge from a different perspective than knowledge supply. The focus on risk communication in online knowledge communities broadens the scope of knowledge management literature beyond the confines of organizations. To the best of the authors’ knowledge, this research is among the first studies to propose risk knowledge design approaches for communicating systemic risks.

Abstract
Purpose
Indigenous peoples represent one of the most vulnerable groups and need access as well as hands-on experience in the use of emerging Earth observations (EO)-based DRR solutions at the community level, while balancing this learning with traditional indigenous knowledge (IK). However, complicating any engagement between EO and IK is the reality that IKs are diverse and dynamic, with location-specific relevance and accuracy. Additionally, the COVID-19 pandemic caused complex risks and cascading effects for which the world was not prepared. Thus, there is a need to examine the lessons learned and motivate emerging EO-based innovations and demonstrations related to DRR and climate change adaptation.
Design/methodology/approach
Hence, this study aims to undertake an in-depth assessment of IK related to DRR covering relevant UN instruments and provides state-of-the-art of opportunities presented by EO-based tools and solutions.
Findings
The overall research strategy was designed to integrate key components of IK for DRR in a coherent and logical way, with those offered by the EO technology developers and providers. There are several EO tools accessible that are relevant to integrate IK and complement DRR. The study examined and identified challenges and barriers to implement workable and replicable EO solutions in pursuit of resilience.
Originality/value
The key findings of this study will help create a balanced approach by acknowledging the importance of IK for DRR with co-development, co-creation and use of culturally relevant EO data and tools for sustainable innovation, capacity building and youth empowerment. The technological inequalities appear to be growing, and it would be challenging to meet the Sendai Framework indicators.

Abstract
Purpose
This research aims to systematically review studies on significant risks for Critical Infrastructure Projects (CIPs) from selected top-tier academic journals from 2011 to 2023.
Design/methodology/approach
In this research, a three-step systematic literature review methodology was employed to analyse 55 selected articles on Critical Infrastructure Risks (CIRs) from well-regarded and relevant academic journals published from 2011 to 2023.
Findings
The findings highlight a growing research focus on CIRs from 2011 to 2023. A total of 128 risks were identified and grouped into ten distinct categories: construction, cultural, environmental, financial, legal, management, market, political, safety and technical risks. In addition, literature reviews combined with questionnaire surveys were more frequently used to identify CIRs than any other method. Moreover, oil and gas projects were the subjects most often explored in the reviewed papers. Furthermore, it was observed that publications from Iran, the USA and China dominated CIRs research, making significant contributions, accounting for 49.65% of the analysed articles.
Research limitations/implications
This research specifically focuses on five types of CIPs (i.e. roadways, bridges, water supply systems, dams and oil and gas projects). Other CIPs like cyber-physical systems or electric power systems, were not considered in this research.
Practical implications
Governments and contracting firms can benefit from the findings of this study by understanding the significant risks associated with the execution of CIPs, irrespective of the nation, industry or type of project. The results of this investigation can offer construction professionals valuable insights to formulate and implement risk response plans in the early stages of a project.
Originality/value
As a novel literature review related to CIRs, it lays the groundwork for future research and deepens the understanding of the multi-faceted effects of these risks, as well as sets practical response strategies.
