Elementary differential calculus is used to analyze and to discuss some complex economic situations. (JT)

The author uses mathematical models that involve only algebra and a few basic ideas in discrete probability to describe the frequency of conception in large human societies. A number of calculations which can be done by students as exercises are given. (MN)

Some one dimensional search procedures for finding optimal solutions to a unimodal function are explored. (MN)

Mathematical observations are made about some continuous curves, called transitions, encountered in well-known experiences. The transition parabola, the transition spiral, and the sidestep maneuver are presented. (MNS)

The author argues that a new approach to the teaching of statistics to bright students training for administrative careers is needed. (SD)

The functions of a mathematician in industry are analyzed and suggestions are given concerning the mathematical training that would be appropriate. (DT)

The need for realistic applications to be included in mathematics courses is stressed. Several general examples of realistic problems are suggested. (DT)

This article describes a mathematics course in which industrial and governmental problems are addressed, studied, and solved by teams of students working under faculty supervision. (DT)

Three short articles on teaching procedures are presented. They concern: (1) a simple introduction to the derivative; (2) using derivatives to solve polynomial equations; and (3) mathematical applications in problems concerning force due to gravity. (JG)
