Taking Human Capital Investment Seriously: Reflections on Educational Reform

This paper presents the 2002 Junior College/Upper Secondary Review in Singapore in the context of the nation-states commitment to human capital investment. It discusses how these changes have led to a radically altered upper secondary educational landscape through the implementation of the Integrated Programme, the establishment of Specialized Schools in Sports, Maths and Science, and the Arts, and the introduction of Privately Funded Schools. These rapid changes have greatly diversified the educational opportunities available to students in this relatively centralized educational system in a short period of time. The concluding thoughts section concludes with implications of such educational change for parents, students and teachers and issues to be considered while they negotiate such educational change.

A quadratic programming method for optimal degree reduction of Bezier curves with G^1-continuity

This paper presents a quadratic programming method for optimal multi-degree reduction of Bézier curves with G1-continuity. The L2 and l2 measures of distances between the two curves are used as the objective functions. The two additional parameters, available from the coincidence of the oriented tangents, are constrained to be positive so as to satisfy the solvability condition. Finally, degree reduction is changed to solve a quadratic problem of two parameters with linear constraints. Applica     

Degeneracy cases of generalized inverse function-valued Padé approximation

A new generalized inverse function-valued Padé approximation (GIFPA) was defined. Existence condition of GIFPA was given and its uniqueness theorem was proved. All possible degeneracy cases of GIFPA were discussed and constructed. An example was given to illustrate its application.
