attentional limits of the driver. Currents ergonomics studies assessed methodologies in order to
measure and predict the workload, distracting effects or risk behaviours by resting on early
psychological processing and models. Our aim is to draw methodologies from current cognitive
assumptions of multiple-task situations revealing switch cost and multiple resources limitations.
4165.3 Introspective methods in human-computer interaction research and practice, Torkil
Clemmensen, Department of InformaticsCopenhagen Business School, Denmark
The usability of interactive products is often ensured through empirical assessment. Thus the
introspective methods of ‘thinking aloud’, ‘constructive interaction’ and others have shown their
great practical value. However, the classical objections to the various uses of introspective
methods in psychology need to be revisited, when applying introspection in new fields. A review
of human-computer interaction studies shows that the theory most often referred to in the literature,
Ericsson and Simon 1984, is incompatible with most of the techniques applied, and that we need
to consider recent proposals for alternative theoretical frameworks for introspective methods in
human-computer interaction.
4165.4 Necessary dimensions to effective global supply chains: The role of national culture,
Pamela Yeow, Sue Hornibrook, University of Kent, UK
In order to manage perceptions of risk associated with food quality and safety, vertically
co-ordinated supply chains have emerged in the UK (Hornibrook 2001, 2003). Given the
importance of attitudes and beliefs in determining risk perception, and the emergence of global
supply chains in food and other consumer products, interdisciplinary research is required to
investigate the role of culture in determining perceived risk, and the consequent influence on
organisational buying behaviour. With the aim to improve effectiveness in global supply chains,
this paper hopes to provide a framework for analysing the role of national culture in the food
industry.
4165.5 Work design in the third millennium, Marwan Al-Zoubi, University of Surrey, UK
Developments in job design theory have not kept pace with organisational landscape changes.
Using data from 498 employees working in modern jobs, we proposed a job design model that
consists of five hierarchal stages in which fulfilling the previous stage is a pre-requisite to
achieving the one after. The first stage is a list of job characteristics that were developed using
qualitative and quantitative data. The second and third stages are hypothetical framework for
multi-level mechanisms. The fourth and fifth stages are work outcomes (performance and
well-being). We argued that this hierarchical modelling gives a better understanding and deeper
analysis.
