Specifications for surface texture frequently focus on surface 'rough-ness'--the finer structures in the texture--often to the exclusion of the 'wavi--ness'--the larger structure of the texture. Unfortunately, problems related to sealing, [...]

The main purpose of this special issue is to suggest strategies for meeting the mathematical needs of two-year college students in the decade of the 1990s. Since the 20 contributors were free to write about topics that they considered to be appropriate to the intellectual and personal development of all students their papers represent a broad overview of what leading mathematics educators think should be occurring in mathematics education in the 1990s. The articles are separated into the following five broad categories: (1) guiding thoughts about technological innovation, curriculum standards, and concomitant implementation; (2) outlines of curriculum content specific to calculus, discrete mathematics, statistics, and fractal geometry; (3) special considerations regarding remedial coursework and the needs of the learning disabled student; (4) utilization of computer algebra systems, videotapes, and multimedia presentations in the college mathematics classroom; and (5) the content and reasonable uses of placement tests. Each author supplies diagrams and references as appropriate. (JJK)
