This volume of essays grew out of a symposium organized by Judith Hoch-Smith and Anita Spring for the 1974 American Anthropological Association meetings in Mexico City. The two-part symposium was enti tled "Women in Ritual and Symbolic Systems: I. Midwives, Madonnas, and Mediums; ll. Prostitutes, Witches, and Androgynes. " The sym posium participants were asked to explore theological, ritual, and sym bolic aspects-both positive and negative-of the feminine cultural do main, using ethnographic materials with which they were familiar. The resulting papers have been revised, edited, and gathered together in Women in Ritual and Symbolic Roles. The theoretical importance of these papers for the s...

A Sobolev gradient of a real-valued functional is a gradient of that functional taken relative to the underlying Sobolev norm. This book shows how descent methods using such gradients allow a unified treatment of a wide variety of problems in differential equations. Equal emphasis is placed on numerical and theoretical matters. Several concrete applications are made to illustrate the method. These applications include (1) Ginzburg-Landau functionals of superconductivity, (2) problems of transonic flow in which type depends locally on nonlinearities, and (3) minimal surface problems. Sobolev gradient constructions rely on a study of orthogonal projections onto graphs of closed densely defined linear transformations from one Hilbert space to another. These developments use work of Weyl, von Neumann and Beurling.
Analyzes the potential for generating savings for Latin America and for several countries in the region. Examines the contribution of savings to the process of capital formation, the relationship between domestic savings and domestic investment, and the effects of foreign investment on savings and capital investment in the region. Specific topics include foreign sources of long-term financing for borrowers in Brazil, the use of ADRs to finance investment in Colombia and Latin America, and Chilean pension fund reform and its impact on savings.
