Application of Information Theory Concepts in the Investigation of the Growth Pattern of Production, Distribution and Velocity of Information

Description: The objective of this research is the investigation of the patterns of information growth to test whether there has been an "information explosion." To tackle the main problem, there are three issues which need to be addressed: (1) the concept of information dimensionality; (2) determination of common parameters to measure the amount of information within each dimension; and (3) a working definition of "explosiveness.

Interactions of Presentation Formats and Decision-Maker Characteristics upon Multiple Decision-Making Tasks: an Experiment Using Multiple Cognitive Assessments

Description: Information systems research tends to ignore individual differences in users. This laboratory experiment sought to illuminate contributions of decision-makers' cognitive processes to decision outcome as reflected in four hypothesis sets: the impact of imagery preference and presentation format upon (HI) recall accuracy and upon hemispheric activation during (H2) encoding and (H3) recall, and (H4) to examine the relationship between hemispheric activation differences and accuracy differences.

The Relationships of Cross-Cultural Differences to the Values of Information Systems Professionals within the Context of Systems Development

Description: Several studies have suggested that the effect of cultural differences among Information Systems (IS) professionals from different nations on the development and implementation of IS could be important. However, IS research has generally not considered culture when investigating the process of systems development. This study examined the relationship between the cultural backgrounds of IS designers and their process-related values with a field survey in Singapore, Taiwan, the United Kingdom and… more
