Why is Electronic Commerce (E-Commerce) not the runaway success it was supposed to be? Instead of hearing or reading about wonderful achievements we appear to be finding an increasing number of stories ranging from disappointment to despair. In this paper it will be argued that the term e-commerce means too many things to too many different people, and it will be shown that a number of variants...

In an experimental setting, we investigated whether body shape similarity between user and interface character affected involvement with, distance towards, as well as intentions to use the character in an e-health context. Users interacted with an interface character with the same (similar) or with a different (dissimilar) body shape as their own. Furthermore, the character’s body shape was neg...

We prove that cyclic Petri net reachability sets are nite unions of linear combinations of integer vectors whose sizes are exponential in the size of the cyclic Petri net.

Facing pressure from an increasingly competitive business environment, small and medium-sized enterprises (SMEs) are called upon to implement e-Learning strategies to support their organizational training and developmental efforts. The purpose of this study is to identify the barriers and constraints SMEs experience when they want to use e-Learning and to determine, through a multiple case stud...

In terms of public services, governments do not yet know how to treat users as different and unique individuals. At worst, users are still considered an undifferentiated mass, or at best as segments. However, the benefits of universal personalisation in public services are within reach technologically through egovernment developments. Universal personalisation will involve achieving a balance b...

We show that a group admits a planar, finitely generated Cayley graph if and only if it admits a special kind of group presentation we introduce, called a planar presentation. Planar presentations can be recognised algorithmically. As a consequence, we obtain an e↵ective enumeration of the planar Cayley graphs, yielding in particular an a rmative answer to a question of Droms et al. asking whet...
