Are client ties pre‐entry resources? Performance implications of client tie diversification
Strategic Management Journal, EarlyView.Abstract Research Summary This study investigates client tie diversification, where firms enter markets with existing clients. Recognizing the theoretical basis for both positive and negative performance implications, the paper adopts a question‐driven approach and discovers a strong negative correlation between client tie diversification and firm ...

Dynanics of a vehicle-track coupling system at a rail joint [PDF]
, 2015 The dynamic behaviour at a rail joint is examined using a two-dimensional vehicle–track coupling model. The track system is described as a finite-length beam resting on a double-layer discrete viscous-elastic foundation.
