Long Term Human-Computer Interaction

Long Term Human-Computer Interaction

This book is about longitudinal research in Human-Computer Interaction (HCI). Since the early 1980s much has been understood about the problems of novices learning new systems as well as the performance of expert users. However there is still a lot to discover about the transition from novice to expert and its implications for the design of systems. For instance: - How long does it take to become expert? - Does early experience of a system have any effect on subsequent flexibility? - How can flexibility and long term learning be promoted? - Are there strong constraints that should be taken into account in the design of adaptive systems? Longitudinal research in HCI has been rare for many reasons. There is always pressure to obtain results - the current climate of short-termism does nothing to promote a longer perspective. The field of HCI itself is changing fast, and there are often virgin technologies to explore which can be more ex­ citing and potentially profitable than research aimed at basic understanding. There is also a possibly mistaken view that longitudinal studies are always inherently expensive. The present volume grew out of a project at Sydney University. The very first ideas were discussed in 1989. In 1991 data logging started of a mainly undergraduate population using a Unix-based editor, sam(Pike 1987}. Due to good fortune the system continued unchanged into a second year and it became clear data collection had very low marginal costs.

Guillain-Barré Syndrome

Guillain-Barré Syndrome

Richard A.C. Hughes; P.K. Thomas

Springer London Ltd

The period that followed World War II has witnessed a dramatic change in neurology. From being a discipline in which its partici- pants were castigated for being interested solely in diagnosis, usually of disorders of unknown causation without effective therapy, neurology has evolved into a highly active treatment- orientated subject. This transition is clearly reflected in the ap- proach to diseases of the peripheral nervous system, and to the Guillain-Barre syndrome (GBS) in particular. In a state-of-the- art review made in 1952, Elkington (1952) observed that no less than 56% of neuropathies remained undiagnosed, and amongst those of unknown causation he listed GBS. With intensive in- vestigation and follow-up, the proportion of neuropathies seen at tertiary referral centres which elude diagnosis is now as little as 13% (McLeod et al. 1984). Overall, of course, the proportion is even less. This change is partly because of the introduction of new diagnostic techniques and partly because of the application of the great expansion in knowledge evident throughout medicine. In this book, Professor Richard Hughes has assembled current information on GBS and related disorders, including chronic in- flammatory demyelinating polyneuropathy (CIDP), the existence of which was not appreciated until Austin's perspicacious study published in 1958. In the Introduction, Professor Hughes gives an account of the way in which recognition of the GBS emerged and matured, and shows that it followed, pari passu, with the realisation that paral- ysis and sensory loss may result from peripheral nerve disorders.
