MIS researchers have developed a number of models for studying the software utilization choices of end users, including the Task-Technology Fit Model and the Technology Acceptance Model. We are exploring the similarities and differences among these models with a goal of developing combined models with more explanatory power. This paper proposes a model that extends the task-technology fit model...

This paper presents a novel approach of exploring usage analysis in learning systems by means of graphical representations. Learning systems collect large amounts of student data that can be used by instructors to become aware of what is happening in distance learning classes. Instead of being processed with techniques from user modelling, data is displayed “as it is”. Techniques from Informati...

These outcomes bypass some of the problems with self-reports and directly measure a component of healthcare costs associated with heavy drug usage. The price elasticity of the probability of a cocaine and heroin episode is estimated at -0.27 and -0.10, re...
