The business artifact (a.k.a. business entity) approach to modeling and implementing business operations and processes is based on a holistic marriage of data and process and enables a factoring of business operations based on key business-relevant conceptual entities. The recently introduced Guard-StageMilestone (GSM) artifact meta-model provides a hierarchical and declarative basis for specif...

Collaborations such as Wikipedia are a key part of the value of the modern Internet. At the same time there is concern that these collaborations are threatened by high levels of member turnover. In this paper we borrow ideas from topic analysis to editor activity on Wikipedia over time into a latent space that offers an insight into the evolving patterns of editor behavior. This latent space re...

Information systems (IS) have become the organisational fabric for intraand inter-organisational collaboration in business. As a result, there is mounting pressure from customers and suppliers for a direct move away from disparate systems operating in parallel towards a more common shared architecture. In part, this has been achieved through the emergence of new technology that is being package...

Managing the information stewardship lifecycle is a challenge. In the context of cloud computing, the stakeholders in cloud ecosystems must also take account of the demands of the information stewardship lifecycles of other participants in the ecosystem. We describe a modelling framework — incorporating tools from mathematical systems modelling, economics, and policy/user modelling — suitable f...

This paper re-appraises Peter Naur’s influential paper on Programming as Theory Building in the context of modern software engineering practice. The central argument is that such practice is focussed primarily on methods, notations, lifecycles and the description of artifacts such as models. Instead we propose that a theory building view is more appropriate, and that the concept of a theory sho...

North Atlantic tropical and post-tropical cyclones impact midlatitude regions, but the inhomogeneous observational record of latter stages precludes many climatological analyses. The frequency tropical-origin storms basin-wide is projected to increase under anthropogenic climate change, so establishing confidence in our knowledge their historical variability lifecycles—against which model simul...
