Comment on Alternative Monies and the Demand for Media of Exchange
Professors Santomero and Seater have put considerable energy into building and analyzing a carefully crafted mathematical model with a narrow microbanking focus. They explore the representative consumer's willingness to substitute electronic money (which they portray as plastic-based "smart cards" with no nontransactional informational processing or communications usages) for paper-based "traditional money." Their model concerns itself only with what we could call pocket money and "pocket electronic platforms." The question I wish to explore in my remarks is where can we go from here: How can this first-cut model be made to cast more light on the problem of persuading households to dive deeply into electronic banking?
The Market for Electronic Cash Cards
We develop a theoretical framework aimed to model the pricing of electronic cash cards and the market domain in which these cards will be used in an environment where charge cards and currency (the legal tender) are competing payment media. We also investigate whether the adoption of the various payment media generates an underutilization or overutilization of the electronic cash cards relative to currency.
Inferring Learning Strategies from Students ’ Errors
Student models in an Intelligent Tutoring System (ITS) aim at representing both correct and incorrect knowledge of the student in a particular domain of learning. This data serves as the basis upon which the Tutor can dispense remedial feedback. This paper presents a framework in which learners’ errors are diagnosed, classified and linked to cognitive processes associated with learning. The cognitive processes we identify are those of generalization, misattribution and ignorance. Our system applies to the domain of Second Language Acquisition and our approach uses Chomsky’s linguistic theory of Principles and Parameters. We particularly concentrate on the acquisition of the Phrase Structure component.
