AN ASSESSMENT OF THE IMPACT OF THE RURAL EMPOWERMENT ZONE AND ENTERPRISE COMMUNITY PROGRAM ON TEXAS' RIO GRANDE VALLEY
A Human Development Index (HDI) was developed to analyze the impact of the rural empowerment zone program on counties in the Texas Rio Grande Valley. Results of the analysis indicate that minimal development has taken place in these counties. This outcome is attributable to several institutional factors.Community/Rural/Urban Development,

An Assessment of the Efficiency of Agribusiness Trucking Companies: A Data Envelopment Analysis Approach
The purpose of this study is to investigate the issue of efficiency in the U.S. motor carrier industry using DEA and SFA. While both methods used the same variables, the resulting efficiency scores were significantly different. This leads to the question of which method is a better measure of efficiency.Public Economics,

Two-meson cloud contribution to the baryon antidecuplet binding
We study the two-meson virtual cloud contribution to the self-energy of the
SU(3) antidecuplet, to which the Theta+ pentaquark is assumed to belong. This
is motivated by the large branching ratio of the N(1710) decay into two pions
and one nucleon. We derive effective Lagrangians that describe the N(1710)
decay into N-pi-pi with two pions in s or p wave. We obtain increased binding
for all members of the antidecuplet and a contribution to the mass splitting
between states with different strangeness which is at least 20 % of the
empirical one. We also provide predictions for three-body decays of the
pentaquark antidecuplet.Comment: 13 pages, To appear in Phys. Rev.
