“User centred design” (UCD) has become a central, largely unquestioned, tenet of good practice for the design of interactive systems. With the increasing recognition of the importance of special needs in influencing design, UCD needs to be re-examined, in particular to be clear about the difference between using its methods, which may not suit special needs, and achieving its objectives. This p...

In this position paper I introduce the idea of having a usability designer role in development projects to enhance a user-centred design approach. This role is responsible for the usability in all phases of development, integrating usability design into the development process. It is my experience that there is a need for this kind of role, advocating for usability in the organisation and in al...

We compute an array of Standard Model Higgs boson (H) signals and backgrounds for a possible upgrade of the Tevatron to √ s = 4 TeV. Taking m t ≥ 140 GeV, and assuming a total accumulated luminosity of L = 30 fb −1 , we find that a Standard Model Higgs boson with m H < ∼ 110 GeV could almost certainly be detected using the W ± H → lνbb mode. A Higgs boson with mass between ∼ 120 GeV and ∼ 140 G...

Research efforts focused on developing "active reports" are currently underway. Active reports are designed to foster communication among teachers, students, and parents by listening to all stakeholders, using assessment information to guide teaching and learning, and to reconcile potential conflicts. Open student models can handle different views of the student. These views support different k...
