Task constraints and user-system interaction process under personnel decision support

Article Abstract:

A study of 36 subjects was carried out to examine user-system interaction and utilization of information regarding decisions. The study was based on personnel management data from 8 Chinese enterprises. The process-tracing techniques revealed that the user's weights of decision information attributes were correlated with the types of information search patterns in using decision support systems. More focussed search techniques were used by the subjects in high time-pressure and chunking representation conditions.

Expertise in dynamic environments

Article Abstract:

Expert operators are better at producing inferences and anticipating, and have a more functional view while supervising dynamic environments as compared to novice operators. Expertise is measured according three components of process control; monitoring, diagnosis and decision making, and executive control. Divergent relationships are present between expertise and reasoning directionality, knowledge depth of the semantics of the process and synchronization of actions.
