Simulation is a vital tool in research methods for investigating lifecycle issues in critical application areas, such as scenarios involving trust. Our trust model is premised on the belief that the ability to form and evolve explicit values for trust in other principals in an interaction allows...

An enormous amount of information has been produced about the IT outsourcing phenomenon over the last 20 years, but one has to look to the academic literature for consistent, objective, and reliable research approaches and analyses. Our review finds that, in practice, the academic literature on...

Publishing transaction data containing individuals? activities may risk privacy breaches, so the need for anonymizing such data before their release is increasingly recognized by organizations. Several approaches have been proposed recently to deal with this issue, but they are still inadequate...

In this paper we study a new restriction of the PAC learning framework, in which each label class is handled by an unsupervised learner that aims to fit an appropriate probability distribution to its own data. A hypothesis is derived by choosing, for any unlabeled instance, the label whose...

Based on multiple-case research, this paper develops a model of strategic information systems (IS) investment in small and medium-sized enterprises (SMEs). IS investment is modelled as a function of an SME's strategic context as defined by its strategic focus, i.e. cost reduction versus value...

The purpose of this thesis is to introduce a new broad approach to computing - Empirical Modelling (EM) - and to propose a way of applying this approach for system development so as to avoid the limitations of conventional approaches and integrate system development with business process...

Liberalisation of telecommunications encourages competition between the various actors in the Open Service Market (OSM). In this highly competitive context, Connectivity Service Providers (CSPs) and Value Added Service Providers (VASPs) are investigating opportunities to provide differentiated...

This paper presents a model, which allows managers to identify the influence of their decisions to the potential innovation activity of the firm by simulation. Systems Thinking methodology has been used to understand the framework of innovation systems and to design and run the simulation model....

This paper is concerned with optimizing financial programs through the use of performance models to promote the best use of available computational resources, The work necessarily focuses on run-time optimization, where a performance model of the program is combined with knowledge of run-time...

For businesses planning interactions online, particularly using Web services, managing risks and accommodating each other's varying business-level security requirements is a complex but critical issue during development. Literature suggests numerous reasons that prohibit the simplistic adoption,...
