This paper aims to investigate the rebound process and the secondary-impact process of the fuselage section that occurs in the actual crash events.

Abstract

Purpose

This paper aims to investigate the rebound process and the secondary-impact process of the fuselage section that occurs in the actual crash events.

Design/methodology/approach

A full-scale three-dimensional finite element model of the fuselage section was developed to carry out the dynamic simulations. The rebound process was simulated by removing the impact surface at a certain point, while the secondary-impact process was simulated by striking the impact surface against the fuselage bottom after the first impact.

Findings

For the rebound process, the fuselage structure restores deformation due to the springback of the fuselage bottom, and it results in structural vibration of the fuselage section. For the secondary-impact process, the fuselage deformation is similar with that of the single impact process, indicating that the intermittent impact loading has little influence on the overall deformation of the fuselage section. The strut failure is the determining factor to the acceleration responses for both the rebound process and the secondary-impact process.

Practical implications

The rebound process and the secondary-impact process, which is difficult to study by experiments, was investigated by finite element simulations. The structure deformations and acceleration responses were obtained, and they can provide guidance for the crashworthy design of fuselage structures.

Originality/value

This research first investigated the rebound process and the secondary-impact process of the fuselage section. The absence of the ground load and the secondary-impact was simulated by controlling the impact surface, which is a new simulating method and has not been used in the previous research.

Abstract

Purpose

To provide a theoretical perspective on and an empirical understanding of the decline in Phuket's tourism, the secondary impact of the 2004 tsunami.

Design/methodology/approach

Based on qualitative field research intermittently conducted between February and July 2005, this paper describes the process and mechanism of this secondary impact (the reputational disaster) in Phuket. The main data sources are semi‐structured interviews with Thai and Japanese workers at hotels, restaurants and tour operating companies.

Findings

In the disaster‐stricken beach resorts of Thailand the effects of the tsunami can be seen as a long‐term socioeconomic phenomenon. The decrease in the number of tourists has brought about serious stagnation in the regional economy. The post‐tsunami tourism decline is a complex process involving risk‐induced stigmatization of the region and historically embedded vulnerabilities in the local society.

Research limitations/implications

This paper does not provide quantitative data and analysis. The research should be treated as pilot‐research for further study.

Originality/value

This paper focuses on the secondary socioeconomic effects of the tsunami in this tourism‐oriented area. This topic has as yet only been briefly examined. In addition, the concept of “reputational disaster” is introduced so as to expand the perspective of the risk‐induced stigmatization model based on a social amplification of risk framework.

Abstract

Purpose

This article analyzes the challenges of infectious disease control under a super-aged society through Japan’s experience with COVID-19.

Design/methodology/approach

This article provides an overview of Japan’s COVID-19 measures and their characteristics, discusses their successes and failures, and identifies future challenges.

Findings

Japan’s basic strategy for COVID-19 consists of three parts: the border defense (Stage 1), slowing down the spread (Stage 2), and damage control (Stage 3). One key policy feature in Stage 2 and Stage 3 is based on “voluntary restriction”. It had a certain effect, but it was prolonged with each recurring “wave of infection”, resulting in economic exhaustion and people’s dissatisfaction. Thus, the effect of the voluntary restriction has weakened, while the percentage of people who have been vaccinated is improving, making it difficult to predict the damage of the next “wave”. Under the hyper-aged society, it was necessary to identify and protect particularly vulnerable areas, i.e., psychiatry hospitals, chronic care hospitals, and long term care (LTC) facilities. On the other hand, secondary impacts extend to young people. The most serious one is the decrease in births which further accelerates the aging of society.

Originality/value

This study is original as it investigated why Japan’s unique countermeasures against COVID-19 without mandatory lockdown worked well for a considerable period. It also revealed that secondary impacts of the COVID-19 epidemic are broader and more significant than the direct loss of life, and that the social system, especially super-aged society with many vulnerable areas should be reformed in consideration of the threat of infectious diseases. Lessons from the Japanese case may contribute to other countries.

Abstract

Purpose

This paper aims to investigate drought impacts and vulnerabilities specific to mountain resort communities and the implications for the tourism industry, in order to derive a set of recommendations for reducing drought vulnerability of this economic sector.

Design/methodology/approach

This article presents the results from a case study conducted in Colorado, USA, mountain communities evaluating the multi‐year drought that culminated in 2002. Using qualitative research methods, a series of interviews were conducted to garner the experiences of state and local tourism officials, ski resort representatives, and environmental, municipal and agricultural organizations.

Findings

This study finds that drought alone was not responsible for creating the variety of direct and secondary impacts on Colorado resort communities. The paper highlights the importance of water resources to the economic wellbeing of resort communities and recognizes the critical roles of communication, planning, media and public perception during a drought.

Originality/value

Societal vulnerability in mountain resort communities in relation to drought has rarely been addressed in the literature. The study provides specific recommendations to the resort managers and tourism officials for mitigating drought impacts of, and reducing resort communities' vulnerability to, drought.

Abstract

This chapter describes the approach to sustainable rail passenger rolling stock in terms of interior passive safety requirements within the European market. It is intended to give the background and logistical approach for the future introduction of a standard as an aid for the design and validation of the interiors of passenger rail vehicles. Also discussed is the acceptance of the proposed European-based standard into the regulatory system of the technical specifications for interoperability. Methodologies for design assessment and validation will be discussed. This chapter is intended to encourage an acceptance of the standard for interior passive safety as a realistic and cost-effective method of improving rail vehicle safety in terms of the passenger interfaces with the rail stock interior.

Abstract

Purpose

This paper seeks to highlight a poorly‐understood dimension of digital exclusion that is not related to access to information and communication technologies (ICTs), but rather to the reduction in flexibility for providing and administering public services following the implementation of an integrated e‐government system.

Design/methodology/approach

A case study of a project focused on reducing barriers to the delivery of driver licensing services to a remote indigenous community in Australia was undertaken and the data were analysed using Kling et al.'s socio‐technical interaction network (STIN) modelling approach.

Findings

The paper makes four recommendations to improve the licensing situation for the community that are induced from the findings. In particular the paper draws attention to the need to carefully analyse possible negative impacts of any e‐government initiative for those at the margins of society.

Research limitations/implications

The paper aims to analyse the current situation as the foundation for recommending future actions. These can form the basis for subsequent interventions in the licensing situation.

Practical implications

This research provides an outsiders' overview of the licensing situation and recommendations for change that take account of a diversity of viewpoints and interests.

Originality/value

The paper contributes to our understanding of the relationship between ICTs and social exclusion in three ways. It provides a rich narrative describing the secondary impacts of integrated e‐government systems, a theoretically grounded analysis of the situation and some recommendations for addressing some of the implications at both the community level as well as calling for more careful evaluation of possible negative consequences about shifting service provision to integrated systems.

Abstract

Purpose

The purpose of this paper is to introduce econo-political risks (EPRs) to supply chains (SCs). Based on case data from an automotive SC, this research identifies the mechanisms through which a subset of EPRs influences SC operations and outcomes.

Design/methodology/approach

An exploratory case study method is employed for theory development. Interviews with SC professionals of three case companies were the primary data source. Company documents, archival records, and direct observation provided further insights into how EPRs are perceived, how they impact a SC, how SC actors react to them, and what the overall performance results are.

Findings

The research identifies EPRs in terms of scope (flow of material, money, and knowledge) and time, and provides concrete examples, along with the channels through which their impact unfolds, and the responses available to SC actors. The authors find secondary impacts of EPRs through economic and regulatory channels to be significant, and bankruptcy, strategic reorientation, and single sourcing are common outcomes. By elaborating on the mechanisms through which sanctions impact upon SCs, and the feasible response trajectories, this research can assist SC actors with more effective management of EPRs.

Originality/value

This paper is novel for three reasons: first, it introduces EPRs to research into supply chain risk management (SCRM); second, it addresses SC risks in a developing country, a topic largely missing from the literature; and finally, this research focuses on post-event SC risks, whereas the bulk of SCRM literature focuses on the pre-event phase.

Abstract

This paper argues that, together with improved protection structures and energy dissipation systems, a favourable occupant position with sufficient support and restraint could reduce fatalities in aviation accidents. The crash responses of three different occupant positions were compared to justify the proposal of supporting a pilot in the rather unusual prone position. The normal seated and supine seated positions have already been adopted and implemented in aircraft. The occupant's response to specified crash pulse shapes in these two positions was compared with that of an occupant in the prone position. To obtain the best prone support configuration, different concepts were considered during the analysis. A dynamic event simulation program called ADAMS was used to perform the analysis, and existing injury criteria and a study of common causes of aviation fatalities and human body tolerance limits were used to compare the results. The study indicates that higher crash survivability in the prone position could be achieved if several guidelines are followed.
