Abstract
Purpose
School buildings have suffered disproportionate damage during past and recent earthquakes. For example, during the 2008 Sichuan earthquake, many school buildings collapsed, resulting in loss of life. School buildings in many other parts of the world are also susceptible to this type of widespread damage because of inadequate design, detailing, or poor construction quality. The purpose of this paper is to show how these fatal flaws can be mitigated prior to future catastrophe by using good engineering practice to retrofit vulnerable schools.
Design/methodology/approach
Conventional and innovative, cost‐effective, and reliable tools are available to prevent damage to schools. It is often necessary to examine a group of buildings or all structures in a locality and develop a comprehensive risk management plan for the vulnerable buildings. As an example, a comprehensive evaluation and retrofit project, under the auspices of the World Bank, is currently under way in Istanbul, Turkey, to address vulnerable school and hospital buildings as discussed in the paper. As part of this effort in Turkey, a guideline that relies on state‐of‐the‐art evaluation and retrofit methods has been developed to assist the local engineers.
Findings
Implementation of the program based on the uniform standards developed in the retrofit guidelines, has significantly reduced the seismic risk to schools in Istanbul.
Practical implications
The proposed evaluation and implementation technique can be utilized by governments worldwide to prevent further damage to key infrastructure and save millions of lives.
Originality/value
Innovative retrofits can be used to provide enhanced performance and provide seismic resiliency for cluster of school buildings.

Abstract
Purpose
Seismic isolation, as an effective risk mitigation strategy of building/bridge structures, is incorporated into AP1000 nuclear power plants (NPPs) to alleviate the seismic damage that may occur to traditional structures of NPPs during their service. This is to promote the passive safety concept in the structural design of AP1000 NPPs against earthquakes.
Design/methodology/approach
In conjunction with seismic isolation, tuned-mass-damping (TMD) is integrated into the seismic resistance system of AP1000 NPPs to satisfy the multi-functional purposes. The proposed base-isolation-tuned-mass-damper (BIS-TMD) is studied by comparing the seismic performance of NPPs with four different design configurations (i.e. without BIS, BIS, BIS-TMD and TMD) with the design parameters of the TMD subsystem optimized.
Findings
Such a new seismic protection system (BIS-TMD) is proved to be promising because the advantages of BIS and TMD can be fully used. The benefits of the new structure include effective energy dissipation (i.e. wide vibration absorption band and a stable damping effect), which results in the high performance of NPPs subject to earthquakes with various intensity levels and spectra features.
Originality/value
Parametric studies are performed to demonstrate the seismic robustness (e.g. consistent performance against the changing mass of the water in the gravity liquid tank and mechanical properties) which further ensures that seismic safety requirements of NPPs can be satisfied through the use of BIS-TMD.

Abstract
Purpose
The purpose of this paper is to provide a historical account of the significant role that Connecticut businesses and business leaders had in the spread of Lean management throughout the USA. The paper aims to describe what happens when managers do not understand and apply an important principle of Lean management.
Design/methodology/approach
Survey of published and unpublished records, as well as personal communications with key figures.
Findings
Establishes the role and importance of Connecticut businesses and business leaders in the discovery and dissemination of Lean management in America since 1979, external to Toyota and its affiliated suppliers.
Research limitations/implications
The accuracy of some past events necessarily relies on the recollection of key figures that were obtained by personal communications.
Practical implications
Describes how an important principle, “respect for people,” was not understood by most management practitioners, thus hindering efforts to correctly practice Lean management and improve business performance.
Originality/value
The paper provides a historical account of Lean management in America, focusing on activities that occurred in the State of Connecticut post‐1979. Description and relevance of a key area of misunderstanding among practitioners of the Lean management system.

Abstract
Following the discussion at our recent Annual General Meeting, a questionnaire was sent out to all members. Almost half of them replied despite the fact that the time allowed for returning the questionnaire had been kept very short. Some members even provided detailed comments.

Abstract
Purpose
This paper aims to present a general review of the circumstances of America and Japan's rapid corporate, economic and industrial development in the twentieth century.
Design/methodology/approach
The approach considered and evaluated how the circumstances of America and Japan's growth might apply to China and India, two of the fastest growing economies of the twenty‐first century.
Findings
The findings suggest that both America and Japan might be considered exceptional cases and, as such, neither one might be regarded as a good model for emulation. However, the circumstances of Japan's rapid growth appear closer to those of contemporary China and India and on that basis the authors suggest that Japan might be a better model for emulation.
Originality/value
The American model is too novel and unlikely to be imitated, replicated or repeated whereas Japan's high population density, agrarian origins, state assisted and administered development, adaptation and hybridization of local and imported methods and technologies, kinship, pseudo‐kinship and locality based business groupings, and rapid, come‐from‐behind charge toward industrialization, urbanization and international emergence, all suggest that Japan offers a more relevant and useful development model.

Abstract
Purpose
The purpose of this paper is to explain Japan’s role in the peace process on the Korean Peninsula that began in early 2018.
Design/methodology/approach
This paper emphasizes the historical context of international politics in Northeast Asia, rather than power politics or geopolitics. The paper reaffirms the significance of the ongoing peace process on the Korean Peninsula by considering a synthesis of three joint declarations published in 1998, 2000 and 2002 between the Republic of Korea (ROK) and Japan, the ROK and Democratic People’s Republic of Korea (DPRK), and between the DPRK and Japan.
Findings
The normalization of diplomatic relations between DPRK and Japan, along with reaffirmation of the joint declaration between the ROK and Japan, and the Panmunjeom Declaration, would be a base for denuclearizing Northeast Asia.
Originality/value
In Northeast Asia, historical reconciliation among the two Koreas and Japan and peace-building between the two parties on the Peninsula are closely linked. Moreover, the three bilateral relationships among these three parties are also the basis for creating a new multilateral security order in Northeast Asia.
