In this paper, we examine three common modeling techniques – Linear Discriminant Analysis, Logistic Regression Analysis and Neural Networks. Although a wellestablished literature exists examining the relative performances of these techniques, limited organized research attention has been given to the evaluation methods used to determine model and technique superiority. We compare and contrast m...

The paper proposes a framework for understanding the factors that affect usability of e-learning. The framework can be applied to the development of (1) a formative usability evaluation method for e-learning systems and (2) personalisation rules for e-learning systems interface. The formative usability evaluation method is intended for the evaluation of e-learning systems during its development...

The problem of investing y (0) dollars at time 0 to duplicate a contingent claim is formulated as a dynamic optimization problem and solved by the Lagrange method. As an example, the well-known formula of Black and Scholes on option pricing is derived. If the function defining dy (t) is concave in y (t), owing to costs of trading in incomplete markets, there is economy of scale in producing man...
