Abstract

Purpose

This Study aims to present the seismic hazard assessment of the earthquake-prone eastern of Iran that has become more important due to its growing economic importance. Many cities in this region have experienced life and financial losses due to major earthquakes in recent years. Thus, in this study the seismic hazard maps and curves, and site-specific spectrums were obtained by using probabilistic approaches for the region.

Design/methodology/approach

The seismotectonic information, seismicity data and earthquake catalogues were gathered, main active seismic sources were identified and seismic zones were considered to cover the potential active seismic regions. The seismic model based on logic tree method used two seismic source models, two declustered catalogues, three choices for earthquake recurrence parameters and maximum considered earthquakes and four ground motion predicting (attenuation) models (GMPE).

Findings

The results showed a wide range of seismic hazards levels in the study region. The peak ground acceleration (PGAs) for 475 years returns period ranges between 0.1 g in the north-west part of the region with low seismic activity, to 0.52 g in the south-west part with high levels of seismicity. The PGAs for a 2,475-year period, also ranged from 0.12 to 0.80 g for the same regions. The computed hazard results were compared to the acceptable level of seismic hazard in the region based on Iran seismic code.

Originality/value

A new probabilistic approach has been developed for obtaining seismic hazard maps and curves; these results would help engineers in design of earthquake-resistant structures.

Abstract

Purpose

This paper aims to examine the integration of lateral transshipment and road vulnerability into the humanitarian relief chain in light of affected area priority to address equitable distribution and assess the impact of various parameters on the total average inflated distance traveled per relief item.

Design/methodology/approach

After identifying comprehensive critical criteria and subcriteria, a hybrid multi-criteria decision-making framework was applied to obtain the demand points’ weight and ranking in a real-life earthquake scenario. Direct shipment and lateral transshipment models were then presented and compared. The developed mathematical models are formulated as mixed-integer programming models, considering facility location, inventory prepositioning, road vulnerability and quantity of lateral transshipment.

Findings

The study found that the use of prioritization criteria and subcriteria, in conjunction with lateral transshipment and road vulnerability, resulted in a more equitable distribution of relief items by reducing the total average inflated distance traveled per relief item.

Research limitations/implications

To the best of the authors’ knowledge, this study is one of the first research on equity in humanitarian response through prioritization of demand points. It also bridges the gap between two areas that are typically treated separately: multi-criteria decision-making and humanitarian logistics.

Practical implications

This is the first scholarly work in Shiraz focused on the equitable distribution system by prioritization of demand points and assigning relief items to them after the occurrence of a medium-scale earthquake scenario considering lateral transshipment in the upper echelon.

Originality/value

The paper clarifies how to prioritize demand points to promote equity in humanitarian logistics when the authors have faced multiple factors (i.e. location of relief distribution centers, inventory level, distance, lateral transshipment and road vulnerability) simultaneously.

Abstract

Purpose

This study aims to develop the application of the strategic choice approach (SCA) in Karaj City (Iran) as the case study for facilitating the decision-making process concerning uncertainties associated with determining fault trace, fault buffer zone and fault setback, as well as inherent uncertainties related to urban issues – known as wicked problems – which make a clear definition unachievable for them.

Design/methodology/approach

The SCA was recycled in this study to manage uncertain situations in planning. It is designed to deal with problems caused by uncertainty, insufficient knowledge and unpredictable policy outcomes. In combination with the risk-based planning approach, the paper proposes a new model to deal with uncertainty and hazard risk at the same time.

Findings

The results indicated that such decision-making tools are helpful for urban planners who impose changes in the fault zone to save lives and properties where the process seems problematic and ambiguous. Further analysis from the SCA development not only shows that urban planning restrictions should be applied gradually and in pace with the completion of fault displacement geological data but also reveals that defining the implementation process and institutional structure is as important as the preparation of binding fault zoning documents.

Originality/value

The paper will push forward global research and practice because the results can be generalized for use in other earthquake-prone countries, as the considerations and obstacles have a universal character and more specifically because many earthquake-prone countries have not started to define fault avoidance zone restrictions up to now.

Abstract

Purpose

The New Zealand city of Christchurch provides a leading example of post-disaster rebuilding in a Central Business District (CBD) area. In its rebuilding programme, the city has given emphasis to the greening of hospitality and traditional retail space through a combination of development of shared pedestrian spaces (with traffic exclusion and calming) and the integration of greening within the streetscape design. This paper aims to assess whether the development of greened pedestrian areas leads to higher retail spending and, thus, retail rental rates.

Design/methodology/approach

This study uses pedestrian movement data collected from several CBD locations, as well as spending data on retail and hospitality, to assess relationships between pedestrian movements and spending. This study explores retail spending in greened pedestrian shared spaces, and explores how this differs from retail spending in traditional street areas within the Christchurch CBD.

Findings

Spending patterns are location-related, depending on the characteristics of pedestrian space in the selected area. Greened shared pedestrian areas have the highest spending per measured pedestrian for retail and hospitality, whereas traditional street areas have lower spending for retail and hospitality per measured pedestrian, demonstrating the benefits in redeveloped central city areas.

Originality/value

The scope of smart data continues to develop as a research area within urban studies to develop an open and connected city. This research demonstrates the use of innovative technologies for data collection, use and sharing. The results support commercial benefits of greening and pedestrianisation of retail and hospitality areas for CBDs and providing an example for other cities to follow.

Abstract

Purpose

The fresh food supply chain industry faces significant challenges in risk management because of the complexity, immature development and unpredictable external environment of imported fresh food supply chains (IFFSCs). This study aims to identify specific risk factors in IFFSCs, demonstrate how these risks are transmitted within the system and provide an analytical framework for managing these risks.

Design/methodology/approach

A total of 15 risk factors for IFFSCs through extensive literature review and expert consultation are identified and classified into seven levels using interpretive structural modeling (ISM) to demonstrate the risk transmission path. Fuzzy Matrice d’Impacts Croises-Multiplication Appliance Classement (MICMAC) analysis is then used to analyze the role of each factor.

Findings

The interactions of the 15 identified risk factors of IFFSCs, classified into seven levels, are visualized using ISM. The fuzzy MICMAC analysis classifies the factors into four groups, namely, dependent, independent, linkage and autonomous factors, and identifies the relatively critical risk factors in the system.

Research limitations/implications

The findings of this research provide a clear framework for enterprises operating in IFFSCs to understand the specific risks they may face and how these risks interact within the system. The fuzzy MICMAC analysis also classifies and highlights critical risk factors in the system to facilitate the formulation of appropriate mitigation measures.

Originality/value

This study provides enterprises in IFFSCs with a comprehensive understanding of how the risks can be effectively managed and a basis for further exploration. The theoretical model constructed is also a new effort to address the issues of risk in IFFSCs. The ISM and the fuzzy MICMAC analysis offer clear insights for researchers and enterprises to grasp complex concepts.

Abstract

Purpose

Fires have the potential to destroy, resulting in the loss of property and livelihoods, as well as injury, death and repeated trauma for those who are already vulnerable. However, fire as a hazard has been treated rigidly and un-critically, a model that has influenced how it is perceived by policy makers, first responders, engineers and academics and subsequently approaches to implementing and better understanding fire prevention, mitigation, response and recovery from the impacts of fire.

Design/methodology/approach

This article deals with fire, arguing that its case can help imagine what liberation might mean within and for disaster studies. The study argues against dogmatic, outdated, technological and solution-focused perspectives that have constrained how fire and its effects are understood and discuss what disciplinary liberation could mean for the study of fire and its integration within DRR. The study’s approach is based on the DRR Assemblage Theory, which points to fire as an issue at a societal level.

Findings

The study explores the themes of fire and liberation through contributions and insights that have emerged through the authors' professional experience in research and practice. It offers an original and timely engagement with disaster studies through the lens of fire, an increasingly pertinent phenomenon for disaster scholars and practitioners alike.

Originality/value

By drawing on the example of fire as a socio-technical-environmental phenomenon, this paper contributes a novel perspective on the intellectual and practical possibilities that can emerge from disciplinary liberation.

The purpose of this paper is to investigate risk propagation and resilience in the agribusiness supply chain (ASC).

Abstract

Purpose

The purpose of this paper is to investigate risk propagation and resilience in the agribusiness supply chain (ASC).

Design/methodology/approach

The paper undertakes a systematic literature review (SLR). Overall, 94 articles from six databases published between 2000 and 2022 underwent descriptive and thematic analysis.

Findings

There is a lack of research on risk propagation and resilience in the ASC for more than two decades. Accordingly, this research fills the gap in the extant literature by advancing the construct of risk propagation and resilience in the ASC and developing a framework proposing directions in risk propagation and resilience in ASC research.

Research limitations/implications

Firstly, only the Web of Science and Scopus databases were mostly used as primary sources while other databases were used as secondary sources to validate search results. Secondly, SLR is based on the peer-reviewed articles, books and conference papers; other non-academic sources relevant to the topic were not included in this paper.

Originality/value

The paper offers a set of constructs for understanding risk propagation and resilience in the ASC, develops a framework proposing directions in risk propagation and resilience in the ASC research and recommends three key themes for future research directions, namely, keep updated with recent constructs of risk propagation and resilience in the ASC, conduct case studies based on empirical studies to determine the current risk dependency and propagation in the ASC and conduct case studies based on empirical studies to determine resilience and sustainability in the ASC.

Abstract

Purpose

The purpose of this study is to analyze the thermo-diffusion process in a semi-infinite nonlocal fiber-reinforced double porous thermoelastic diffusive material with voids (FRDPTDMWV) in light of the fractional-order Lord–Shulman thermo-elasto-diffusion (LSTED) model. By virtue of Eringen’s nonlocal elasticity theory, the governing equations for the considered material are developed. The free surface of the substrate is governed by the inclined mechanical load and thermal and chemical shocks.

Design/methodology/approach

With the aid of the normal mode technique, the solutions of the nondimensional coupled governing equations have been obtained.

Findings

The expressions of field variables are obtained analytically. By using MATHEMATICA software, various graphical implementations are presented to describe the impacts of angle of inclination, fractional-order and nonlocality parameters. The present model is also validated on the basis of some comparative studies with some preestablished cases.

Originality/value

As observed from the literature survey, many different studies have been carried out by taking into account the deformation analysis in nonlocal double porous thermoelastic material structures and thermo-mechanical interaction in fiber-reinforced medium under fractional-order thermoelasticity theories. However, to the best of the authors’ knowledge, no research emphasizing the thermo-elasto-diffusive interactions in a nonlocal FRDPTDMWV has been carried out. Moreover, the effect of fractional-order LSTED theory on fiber-reinforced thermoelastic diffusive half-space with double porosity has not been illuminated till now, which significantly defines the novelty of the conducted research.

Abstract

Purpose

The purpose of this study is to present the possibilities of co-creation-type reconstruction methods by focusing on examples of reconstruction in communities affected by the 2011 disaster in Japan. This is because the reconstruction of a community is not a matter of supplementing what has been physically lost, but must include social and cultural aspects. We will also conduct research based on the idea that by placing the residents, who are the bearers of the community, in the lead role, we can achieve a recovery that promotes maturity, rather than a recovery that overwrites the community.

Design/methodology/approach

This research was initially conducted for the purpose of reconstruction assistance, but in the process, the author conducted research using information obtained through material surveys on local history and self-governing activities, interview surveys on pre-disaster life, and participatory observation of reconstruction activities. In order to extract knowledge on co-creative reconstruction methods, the author focused on the actual state of cooperation between residents, experts involved in reconstruction support, and the government, based on past research conducted by the author, and extracted what could be considered co-creation from this.

Findings

Co-creative reconstruction is defined as a state in which a shared vision for reconstruction is created by each organization involved in the reconstruction process, with the residents at the core, and collaboration is generated beyond the organizational framework in order to achieve the objectives. This case study can be divided into the following three stages: the stage where the local residents start the recovery process, the stage where a vision for recovery is drawn up based on the recovery project organized by the government, and the stage where collaboration beyond the organizational framework is created to achieve the recovery vision.

Research limitations/implications

Compared to normal urban development, reconstruction projects in disaster-stricken areas are carried out simultaneously in a short period of time. Therefore, in order to capture the details of reconstruction, it is necessary to limit the target area and continue participant observation. However, the limited number of areas to be studied makes it difficult to conduct comparative verification. In addition, the unclear concept of “co-creation” requires the formation of common values through the verification of various case studies. Therefore, it is essential to form an environment in which various case studies can be collected and discussed.

Practical implications

Many of the research reports on earthquake recovery are extracts on specific themes. As a result, it is difficult to obtain an overall picture of how specific areas are recovering. As such, there are few examples that can serve as a reference when confronting reconstruction and an exploratory approach to the unclear future is required. Therefore, this study has practical findings in that it presents concrete sample information by clearly indicating issues and reconstruction systems on a long-term time horizon.

Social implications

It is nonsense to impose a uniform recovery plan in the midst of a mature society with increasingly diverse values. It is necessary to explore the possibility of bottom-up reconstruction in which residents play a leading role as a way to realize individualized and diverse reconstruction. This study presents the possibility of promoting reconstruction while maintaining equal relationships among residents, experts, and the government.

Originality/value

First, the study captures the actual situation of the village before the earthquake and the actual situation of the village during the reconstruction process, using the village as the basic unit. Second, it captures the reconstruction process of the village over a 10-year time frame. According to a specific timeline, the activities, discussions, and institutional changes to promote reconstruction are positioned. Third, in the limited phase of earthquake reconstruction, the project is providing information and analysis from a comprehensive and multifaceted perspective by narrowing down the target areas and continuing high-resolution surveys.
