Inforum Models: Origin, Evolution, and By-ways Avoided
Almon, Clopper
Inforum models combine input-output tables with econometric analysis in dynamic models in which the investment in each industry depends upon the growth of output in that industry. They have been built and used in a number of countries including the USA, Russia, Germany, Poland, Latvia, Austria, Italy, Spain, the United Kingdom, South Africa, Mexico, Colombia, China, Japan, Taiwan, Thailand, and Vietnam and perhaps others. They make extensive use of econometrics and input-output analysis to describe the functioning of an economy not only at a macroeconomic level but also at the level of individual products and industries. This paper records – somewhat autobiographically on the part of the author -- the beginnings of these models, outlines their evolution, defends them and other econometric models against the sweeping Lucas critique, and mentions some of the fads in economics and modeling which have been avoided for good reason.

Path Curves and Plant Buds: an Introduction to the Work of Lawrence Edwards
Almon, Clopper
Lawrence Edwards has shown that many flowering plants have buds with an outline in the form of a path curve, the curve that a point follows under repeated projective transformation of the plane into itself. Edwards, however, did not give a formula for these curves nor did he fit the curves by the standard method of least squares. This paper gives an elementary exposition of the method used by Edwards, shows its relation to projective geometry, and then uses homogeneous coordinates, linear differential equations and characteristic values and vectors of a matrix to derive the formula for path curves. This formula is then used to fit path curves by least squares to data provided by Edwards for the buds of 150 plants. Most buds are fit very closely.

Velia and the Cilento, an Introduction
Almon, Clopper
Material for students in a Study Abroad course beginning in Ascea, near Velia, in Southern Italy. It begins with the geological evolution of the Mediterranean and moves on to the prehistory of the area, the coming of the Greeks, the settlement of Elea = Velia, the Eleatic philosophers, the area in Roman times, and history up to the present, with special attention to the Consorzio Velia, which provides water to the area.
