THE RELATIONSHIP BETWEEN THE AGRICULTURAL AND INDUSTRIAL SECTORS IN CHINESE ECONOMIC DEVELOPMENT
This study examined the interdependency between Chinese agricultural and industrial sectors. A dual economic model was developed to investigate the relationship between the two sectors and factors affecting Chinese economic development. The study reveals traditional inputs, such as labor, are still important to Chinese economic development. Capital investment contributed significantly to the growth of the Chinese industrial sector, but not to the agricultural sector. The results also suggest that foreign trade has made a significant contribution to Chinese economic development. It was found that the growth of the Chinese agricultural sector depends on its industrial growth, but the growth of the Chinese industrial sector does not rely on the agricultural growth.Chinese economic development, dual economy, growth model, agricultural sector, industrial sector, foreign trade, International Development,
VALUE-ADDED WHEAT PRODUCTS: ANALYSIS OF MARKETS AND COMPETITION
This study evaluated the U.S. domestic market for bakery products and identified market size and growth rate by product segment. The competitive structure and dynamics of the baking industry were analyzed including the geographic scope of the market, product structure, minimum efficient scale, processing consolidation, and entry/exit behavior.bakery, consumption, industry, competitive structure., Marketing,
WORLD SUGAR POLICY SIMULATION MODEL: DESCRIPTION AND COMPUTER PROGRAM DOCUMENTATION
The World Sugar Policy Simulation Model is a dynamic, partial equilibrium, net trade model. It distinguishes 18 countries and regions, and sugar is assumed to be a homogenous commodity. The model is designed for evaluating the effects on the world sugar economy of farm and trade policies by simulating production, consumption, stocks, and trade for sugar over a 10- to 15-year period. Figures are not included in the machine readable file--contact the authors for paper copies.International Sugar Trade, Simulation Model Note, Agricultural and Food Policy,
What Not to Wear to a Riot: Fashioning Race, Class, and Gender Respectability Amidst Racial Violence
The descriptions of participants and events in the 1917 East St. Louis riot carried messages about biases. Lou W. Robinson argues that even descriptions of the ways African American women were dressed at the time conveyed biases that sought to question the morals and respectability of women living in East St. Louis at the time
New variable separation approach: application to nonlinear diffusion equations
The concept of the derivative-dependent functional separable solution, as a
generalization to the functional separable solution, is proposed. As an
application, it is used to discuss the generalized nonlinear diffusion
equations based on the generalized conditional symmetry approach. As a
consequence, a complete list of canonical forms for such equations which admit
the derivative-dependent functional separable solutions is obtained and some
exact solutions to the resulting equations are described.Comment: 19 pages, 2 fig
Approximate perturbed direct homotopy reduction method: infinite series reductions to two perturbed mKdV equations
An approximate perturbed direct homotopy reduction method is proposed and
applied to two perturbed modified Korteweg-de Vries (mKdV) equations with
fourth order dispersion and second order dissipation. The similarity reduction
equations are derived to arbitrary orders. The method is valid not only for
single soliton solution but also for the Painlev\'e II waves and periodic waves
expressed by Jacobi elliptic functions for both fourth order dispersion and
second order dissipation. The method is valid also for strong perturbations.Comment: 8 pages, 1 figur
Variational ground states of 2D antiferromagnets in the valence bond basis
We study a variational wave function for the ground state of the
two-dimensional S=1/2 Heisenberg antiferromagnet in the valence bond basis. The
expansion coefficients are products of amplitudes h(x,y) for valence bonds
connecting spins separated by (x,y) lattice spacings. In contrast to previous
studies, in which a functional form for h(x,y) was assumed, we here optimize
all the amplitudes for lattices with up to 32*32 spins. We use two different
schemes for optimizing the amplitudes; a Newton/conjugate-gradient method and a
stochastic method which requires only the signs of the first derivatives of the
energy. The latter method performs significantly better. The energy for large
systems deviates by only approx. 0.06% from its exact value (calculated using
unbiased quantum Monte Carlo simulations). The spin correlations are also well
reproduced, falling approx. 2% below the exact ones at long distances. The
amplitudes h(r) for valence bonds of long length r decay as 1/r^3. We also
discuss some results for small frustrated lattices.Comment: v2: 8 pages, 5 figures, significantly expanded, new optimization
