The depth and breadth of capitalism at the Cape
The Economic History Review, EarlyView.Abstract Limited liability company legislation was introduced to the Cape Colony in 1861. An amendment in 1892 led to wider adoption, expanding and diversifying the capital market. Using novel data from the Cape Joint Stock Archive between 1892 and 1902, this paper examines who invested, where capital flowed, and how these patterns shaped firm outcomes

The aesthetic sublime of megaproject structures: A framework and a research agenda
European Management Review, EarlyView.Abstract The physical structures of megaprojects—such as mega‐canals, metros, railway lines, bridges, tunnels, and iconic opera houses—hold a profound capacity to generate aesthetic experiences with enduring societal impact. Yet, research on megaprojects has predominantly focused on functionality and economic rationale with aesthetics being pushed to ...

Heavy haul rail/wheel wear and RCF assessments using 3D train models and a new wear map
Wear and Rolling Contact Fatigue (RCF) on wheels and rails are influenced by relative motions between the studied rail and wheel pair, and therefore influenced by train dynamics.

Information Systems Journal, EarlyView.ABSTRACT Most organisations are confronting a dilemma: the need to embark on digital transformation to be competitive and sustainable versus the inherently high costs and extremely high risks involved. Lack of executive support has long been identified as a leading cause of project failure, including digital transformation projects.
