The Evolving Role of Women in Mathematics
Marilyn Simon
This article traces the historical exclusion of women from mathematics and science, cites attempts to support their involvement, assesses their current status, and highlights some programs which encourage young women to enter the profession.

Cubic Polynomials
Alan Lipp
A classification of factorable cubics and how the associated factor graphs determine domains of disconnected branches and furnish a skeletal framework for the number and shape of the branches. A second perspective is provided by looking at three dimensional visualization and examining level curves and spikes of the surfaces.
