MEASURING MARKET INTEGRATION IN THE GLOBAL ECONOMY

The increased level of market integration in the processed food industry through trade, foreign direct investment, and the expanded use of intellectual property rights are an observed phenomenon of the past three decades. Measurement of market integration is problematic, and the role of FDI in market integration has not been adequately taken into consideration. This study measures the growth in the market shares of multinationals in selected countries and industries to indicate the degree of market integration. We also employ a market share convergence type model to estimate whether the market shares of the multinationals and domestically owned firms in key markets have converged to some steady state during the years 1991 to 2003.Processed food industry, global integration, market shares, Argentina, Brazil, U.S., International Relations/Trade,

A new view of the spin echo diffusive diffraction on porous structures

Analysis with the characteristic functional of stochastic motion is used for the gradient spin echo measurement of restricted motion to clarify details of the diffraction-like effect in a porous structure. It gives the diffusive diffraction as an interference of spin phase shifts due to the back-flow of spins bouncing at the boundaries, when mean displacement of scattered spins is equal to the spin phase grating prepared by applied magnetic field gradients. The diffraction patterns convey information about morphology of the surrounding media at times long enough that opposite boundaries are restricting displacements. The method explains the dependence of diffraction on the time and width of gradient pulses, as observed at the experiments and the simulations. It also enlightens the analysis of transport properties by the spin echo, particularly in systems, where the motion is restricted by structure or configuration

The Bowl Championship Series: A Mathematical Review

We discuss individual components of the college football Bowl Championship Series, compare with a simple algorithm defined by random walks on a biased graph, attempt to predict whether the proposed changes will truly lead to increased BCS bowl access for non-BCS schools, and conclude by arguing that the true problem with the BCS Standings lies not in the computer algorithms, but rather in misguided addition.Comment: 12 pages, 2 figures, submitted to Notices of the AM

THE IMITATION OF ROMAN CATHOLIC AND BYZANTINE CHANT IN ĒRIKS EŠENVALDS’S PASSION AND RESURRECTION

Ēriks Ešenvalds is an early twenty-first century composer who has been commissioned to write works for some of the most noteworthy ensembles in the world. Having written over 100 compositions to date, 72 of which are choral pieces, Ešenvalds is quickly becoming one of the most prolific and significant composers of his time. He currently works as a full-time composer out of Riga, Latvia. Ešenvalds’s choral works are primarily unaccompanied, while some include brass band, saxophone quartet, percussion, or orchestral accompaniment. Textures vary from three to twelve voice parts. His oratorio Passion and Resurrection (2005), written for soprano solo, SATB quartet, SATB chorus, SS soli, and strings, is an amalgamation of compositional techniques drawn from all eras of music history. This project identifies characteristics of Roman Catholic and Byzantine chant that are imitated throughout Passion and Resurrection. A succinct history of both styles is presented along with a detailing of Ešenvalds’s compositional technique and an overview of his oratorio. Aspects of form, melody, text, rhythm, harmony, and texture present in each movement are also discussed. This study provides conductors with insight into the chant-like aspects of Ešenvalds’s work and any influences on performance. Listings of notable Passion settings and Ešenvalds’s choral output are also included
