AGRIBUSINESS MANAGEMENT OF EXCHANGE RATE RISK

This study did structured interviews with senior agribusiness executives to find out how they managed exchange rate risk and especially deep devaluations of a foreign currency. The Mexican peso crisis was the focus of the study, but the results can be informative when anticipating situations for other countries and currencies.Agribusiness, International Relations/Trade,

A Weyl-covariant tensor calculus

On a (pseudo-) Riemannian manifold of dimension n > 2, the space of tensors which transform covariantly under Weyl rescalings of the metric is built. This construction is related to a Weyl-covariant operator D whose commutator [D,D] gives the conformally invariant Weyl tensor plus the Cotton tensor. So-called generalized connections and their transformation laws under diffeomorphisms and Weyl rescalings are also derived. These results are obtained by application of BRST techniques.Comment: LaTeX, 10 pages. Minor corrections and a reference adde

Book review: listening on the edge: oral history in the aftermath of crisis edited by Mark Cave and Stephen M. Sloan

Listening On The Edge presents excerpts from oral histories done after twelve world crises, followed by critical analyses by the interviewers. Additional analytical chapters set the interviews in the contexts of pyschoanalysis and oral history methodology. This book reminds us that the past is never finished and that the present cannot be ignored, and that telling and listening to testimony “amid chaos” is extremely important, writes Jas Kaur
