Abstracts of Papers for the 14th Annual East Texas Archeological Conference, February 10, 2007

A summary of the analysis of lithics at Los Adaes (16NA16) is presented. Aside from a small number of Late Paleoindian/Early Archaic diagnostics, all stone artifacts recovered at Los Adaes (16NA16) date to the colonial period or later. Colonial stone artifacts include gunflints, probable strike-a-lights, and ground stone fragments, mostly mano fragments. Most of the gunflints appear to be French, while most of the strike-a-light flint appear to be from Central Texas chert. The local gravel cherts do not appear to have been used as either gunflints or strike-a-light flints. The mano fragments are mostly of basalt, which was brought from Mexico

Seed Bead Color Patterns from Colonial Period Sites in Texas and Louisiana

This article focuses on the seed beads recovered from the Spradley site (41NA206), a possible Nacogdoches village site located south of Nacogdoches, Texas, and compares the seed bead color pattern to that of other colonial period sites in the region, including Deshazo (41NA27), Stephens (41NA202), Pearson (41RA5), Gilbert (41RAI3), Roseborough Lake (41BW5), Vinson (41LTI), Womack (41LRI), 41H064, Atlanta State Park (41CS37), Ware Acres (41GG31), and the shipwreck of La Belle in Texas; and Los Adaes (16NA16) and Colfax Ferry (16NA15) in Louisiana. The possible meaning of different seed bead color patterns is briefly discussed

Pay for Performance: Advances in Understanding How Provider Incentives Produce Quality Healthcare

Since the 2000 publication of the Institute of Medicine report, To Err is Human the issue of healthcare quality has been one of the foremost issues in healthcare. According to this report, as many as 99,000 preventable deaths occur annually due to medical errors. Most of these are believed to occur as a result of system errors rather than failure of an individual provider

Sensitivity studies on the shear lag parameter β using analytical and numerical techniques

The strength of fiber-reinforced composites is dependent on the strength of the fiber-matrix interface bond. Thermal, chemical, and other means have been used to modify the surface of fibers, resulting in increased fiber-matrix interface bond strength. However, researchers are still dependent on empirical methods to relate surface modifications to composite performance. Additional efforts are required to develop physics-based models for micro-mechanical effects on interfacial bond strength that will be needed for the improved design and processing of fiber reinforced composites. It is anticipated that experimental, numerical, and analytical efforts will be needed to contribute toward this endeavor. A numerical approach is presented in this thesis that allows the shear lag parameter, β, to be extracted from finite element results. Extracting the shear lag parameter from numerical data allows numerical and analytical approaches to be compared. Axisymmetric finite element analyses of fiber pull out, axisymmetric macrobond, and fully embedded fiber fracture tests are discussed in light of this approach. Material and geometric properties used in numerical models are then varied to study their effects on the fitted value of β. It is anticipated that this approach will enable and enhance future research efforts to simulate the effect of fiber surface texture on pull out strength

Voices from the Texas Pineywoods of El Camino Real de los Tejas: Sabine, San Augustine, and Nacogdoches Counties

The Voices from the Texas Pineywoods of El Camino Real de los Tejas: Sabine, San Augustine, and Nacogdoches Counties provides information for future research in the telling of the story of life ways in three counties of the Texas Pineywoods area of the east-west transportation corridor designated as El Camino Real de los Tejas National Historic Trail

American Indian Pottery from Historic Period Sites in North Louisiana

The following is a revised version of a presentation given at the annual meeting of the Louisiana Archaeological Society (LAS) held in Monroe, Louisiana, on March 4, 2006. The goal of the LAS presentation was to simply show photographs and illustrations of American Indian pottery that dates to the historic period in North Louisiana. Most of the photographs and illustrations are from a manuscript written by H.F. Pete Gregory entitled Los Adaes (16NAJ6) American Indian Ceramics. This manuscript was compiled by George A very as part of the Los Adaes Station Archaeology Program, funded entirely by the Louisiana Division of Archaeology. The LAS presentation was given again at the December 2, 2006 meeting of the East Texas Caddo Research Group (ETCRG) at Stephen F. Austin State University, Nacogdoches, Texas. Revisions to the LAS presentation for the current publication were made as a result of comments from the ETCRG meeting

Family Businesses: Can the Family and the Business Finances Be Separated? Preliminary Results

Small businesses had nearly $1.25 trillion in loans outstanding from commercial lenders, business finance companies, other businesses in the form of trade credit, and friends and relatives in the early 1990s (Ou, 1991). Based on recent information derived from the National Survey on Small Business Finance (NSSBF), loans held by commercial banks and family members or owners of the firm were significant sources of credit, comprising 54 and 18 percent of all loans, respectively (Haynes, 1996). The relative importance of these types of loans suggests that the finances of the business and the family are often intertwined. This study utilizes the recently released Survey of Consumer Finances to examine the impact of small business ownership on the household’s debt structure

Ground-Truthing Excavations at Los Adaes (16NA16) May, 2010

In May 2010, Stephen F. Austin State University—funded by the Army Engineer Research and Development Center (ERDC) Construction Engineering Research Laboratory (CERL)—conducted excavations at Los Adaes State Historic Site (16NA16) to ground-truth the results of a geophysical survey of the presidio area of the site conducted by ERDC CERL and the University of Arkansas at Fayetteville Center for Advanced Spatial Technologies (CAST) in May 2009. The geophysical investigation was a component of a 5-year study funded by the Environmental Security Technology Certification Program (ESTCP). Los Adaes State Historic Site was that project’s demonstration site. This monograph focuses solely on the results of ground-truthing excavations which included the hand excavation of fifteen square meters (fourteen 1x1 and two 0.5x1.0 m units) targeted on carefully selected geophysical anomalies. The anomalies selected for excavation represent suspected historic archaeological features or other deposits of special interest, including wall trenches and other features of the palisade wall of the presidio and structural elements related to interior buildings. For the most part, anomalies documented by the geophysical survey were verified by the field excavations. The wall trench of portions of the eastern and southern palisade were clearly identified by the excavations, and wall sections and interior features of several interior structures documented by the geophysical survey were also verified by the ground-truthing excavations. All artifacts and associated records will be curated with the Louisiana Division Archaeology
