A mathematical analysis of an extended model describing sea ice-induced frequency lock-in for vertically sided offshore structures

This paper presents a mathematical analysis of an extended model describing a sea ice-induced frequency lock-in for vertically sided offshore structures. A simple Euler–Bernoulli beam as model for the offshore structure is used, and a moving boundary between an ice floe and the structure itself is introduced. A nonlinear equation for the beam...

Perceived risk of lock-in in the front-end phase of major transportation projects

Lock-in is defined as the tendency to continue with an inefficient decision or project proposal. The front-end phase is critical to project success, yet most studies have focused on lock-in in the implementation phase. Moreover, little is known about the way in which decision-makers perceive the risk of lock-in. In this paper we identify...

Paradigms and paradoxes: The futures of growth and degrowth

Purpose: The purpose of this paper is to introduce three storylines that address the relation between economic growth, technical innovation and environmental impact. The paper assesses if and how these storylines as guiding visions increase our range of future orientations. Design/methodology/approach: The paper first explains its general...

Cost Overruns in Large-Scale Transport Infrastructure Projects: A theoretical and empirical exploration for the Netherlands and worldwide

In the Netherlands, the costs of railroad infrastructure construction work out 11 per cent higher than forecast; the percentage for roads is 19 and 22 for bridges and tunnels. While this puts the Netherlands in a favourable light compared to other countries, the actual cost overruns are probably far higher, believes Chantal Cantarelli, who...
