Pollution havens versus gates of hell: Environmental pollution and multinationals' foreign investment

open access: yesStrategic Management Journal, EarlyView.
Abstract Research Summary This study investigates an under‐explored cost of operating in pollution havens: the pollution‐induced operational cost, or the increased labor costs and material supply constraints resulting from host countries' environmental pollution.

Switch Rail Reduction Value Deviation’s Impact on Wheel–Rail Dynamic Interaction and Its Efficient Identification Method: A Numerical and Experimental Study

open access: yesApplied Sciences
Railway turnout is a critical railway infrastructure that guides trains in switching tracks. Over time, uneven rail wear can lead to switch rail reduction value (SRRV) deviation, a typical structural defect that compromises turnout functionality and ...

The Seismic Response of High-Speed Railway Bridges Subjected to Near-Fault Forward Directivity Ground Motions Using a Vehicle-Track-Bridge Element

open access: yesShock and Vibration, 2014
Based on the Next Generation Attenuation (NGA) project ground motion library, the finite element model of the high-speed railway vehicle-bridge system is established.

Greenway development and gentrification

open access: yesSouthern Economic Journal, EarlyView.
Abstract This paper presents research on expanding access to green spaces in developed areas. Critics claim greenway projects lead to gentrification by increasing the demand for housing and pushing out residents in nearby neighborhoods. We look for evidence of this phenomenon using a sorting model and panel data on aggregate populations in Atlanta ...

Shinkansen investment before and after JNR reform [PDF]

open access: yes, 2013
Shinkansen' refers to Japan’s dedicated high-speed intercity rail system, and it was initially introduced between Tokyo and Shin-Osaka in 1964 prior to other countries. This event accelerated the development of high-speed railways in other countries.

Complex delay dynamics on railway networks: from universal laws to realistic modelling

open access: yes, 2018
Railways are a key infrastructure for any modern country. The reliability and resilience of this peculiar transportation system may be challenged by different shocks such as disruptions, strikes and adverse weather conditions. These events compromise the

The History and Ideas of George Herbert Mead's Pragmatism and Its Relevance for Operational Research and Systems Thinkers

open access: yesSystems Research and Behavioral Science, EarlyView.
ABSTRACT George Herbert Mead is an oft forgotten or ignored American philosopher who was one of the originators of pragmatism. Today, he is recognised as a creative thinker who has teased out knotty problems that others in the field had not realised were problems. Understanding Mead's analysis has been made difficult because he died prematurely without

Mechanical properties analysis of the interspersed replacement of timber sleepers with bamboo-based composite sleepers on open bridge deck

open access: yesScientific Reports
Due to the discrete deterioration characteristics of timber sleepers on open bridge deck, continuous replacement is difficult. New bamboo-based composite sleepers (BCSs) offer excellent performance at a low price, making them an ideal alternative to ...
