Some Ancestral Caddo Sites on Bayou Loco in the Angelina River Basin, Nacogdoches County, Texas

Archaeological research has been ongoing since the 1930s along Bayou Loco in the western part of Nacogdoches County in the East Texas Pineywoods. Bayou Loco is a southward-flowing tributary to the Angelina River. Jackson note that it was the proposed construction of the Bayou Loco Reservoir (Lake Nacogdoches) in 1972 that led to an important surge in the extent of archaeological research along Bayou Loco, beginning with an archaeological survey, followed up by excavations at several sites that would be inundated by the lake, principally the Mayhew site (41NA21) and the Deshazo site (41NA13/27). The Deshazo site’s Caddo cemetery had been found and excavated by R. L. Turner, Sr. and R. L. Turner, Jr. in 1937, and successful University of Texas (UT) Field Schools led by Dr. Dee Ann Story in 1975 and 1976 uncovered substantial evidence of an historic Caddo farmstead at the expansive site along Bayou Loco. The sites discussed herein are along Bayou Loco and they have been inundated by the waters of Lake Nacogdoches. They were either recorded by Thomas Mayhew, an art teacher at Stephen F. Austin State University in Nacogdoches, Texas, or by Prewitt et al. (1972) during their survey of then proposed Lake Nacogdoches

The Effect of Perceived Parental Style on Hispanic Adults Receiving Outpatient Substance Abuse Treatment in South Texas

Hirschi\u27s (1969) Social Control Theory proposes that parental relationships serve as a shielding factor and has positive impact in the decreasing delinquency (i.e. substance use/abuse) in young people. This theory provides a framework for understanding substance use/abuse in young adult populations. Other factors including gender, cultural influences, family composition and birth order were also examined in this study. The Drug Abuse Screening Test - 20 (Skinner, 1982), the Parental Authority Questionnaire (Buri, 1991), and a demographic scale were utilized in a population of 182 adults in outpatient substance abuse treatment centers in South Texas, Texas Gulf Coast and areas in the south-central part of Texas to examine the relationship between substance abuse, gender, birth order, family composition and perceived parenting style. Results suggested correlations between substance abuse and gender (r=.061), birth order (r=.053), perceived parenting style for both parents (mother, r=-.004; father r=.083) and family composition (r=-.010) at the p\u3c.05 level. A multiple linear regression showed R 2=. 051, adjusted R 2=-.024, F(5,176)=1.894, p=.098, indicating no significant findings. Implications for further research are included regarding substance abuse prevention programs

Elastic p-3He and n-3H scattering with two- and three-body forces

We report on a microscopic calculation of n-3H and p-3He scattering employing the Argonne v_{18} and v_8' nucleon-nucleon potentials with and without additional three-nucleon force. An R-matrix analysis of the p-3He and n-3H scattering data is presented. Comparisons are made for the phase shifts and a selection of measurements in both scattering systems. Differences between our calculation and the R-matrix results or the experimental data can be attributed to only two partial waves (3P0 and 3P2). We find the effect of the Urbana IX and the Texas-Los Alamos three-nucleon forces on the phase shifts to be negligible.Comment: submitted to Phys. Rev.

The Early Formation, Evolution and Age of the Neutron-Capture Elements in the Early Galaxy

Abundance observations indicate the presence of rapid-neutron capture (i.e., r-process) elements in old Galactic halo and globular cluster stars. These observations demonstrate that the earliest generations of stars in the Galaxy, responsible for neutron-capture synthesis and the progenitors of the halo stars, were rapidly evolving. Abundance comparisons among several halo stars show that the heaviest neutron-capture elements (including Ba and heavier) are consistent with a scaled solar system r-process abundance distribution, while the lighter such elements do not conform to the solar pattern. These comparisons suggest two r-process sites or at least two different sets of astrophysical conditions. The large star-to-star scatter observed in the neutron-capture/iron ratios at low metallicities -- which disappears with increasing [Fe/H] -- suggests an early, chemically unmixed and inhomogeneous Galaxy. The stellar abundances indicate a change from the r-process to the slow neutron capture (i.e., s-) process at higher metallicities in the Galaxy. The detection of thorium in halo and globular cluster stars offers a promising, independent age-dating technique that can put lower limits on the age of the Galaxy.Comment: 6 pages, 3 figures; To appear in the proceedings of the 20th Texas Symposium on Relativistic Astrophysics, J.
