A Study of the Contributions of Kelley Ezell to Education Services Programs in the United States Air Force

This study concerns the contributions of Kelley Ezell to Air Force Education Services Programs and examines the impact of his educational leadership in developing the Education Services Program at Sheppard Air Force Base, Texas, into its current position as an officially recognized Air Force leader in program excellence. It determines the effects of his leadership on subsequent leaders in the Sheppard Education Services Center and identifies the systems and procedures which contribute most significantly to the Center's success.

Roads for Texas: Creation of a State Highway Department (open access)

Roads for Texas: Creation of a State Highway Department

The work traces the early history of the Texas State Department of Highways. Beginning with the first efforts to create a department, the study focuses on the period between 1917 and 1923. Much attention goes to the legislative background of the early actions of the department. Subsequently, the work examines various statistical measures of the department's performance. This includes comparisons between Texas and nearby states, and the national highs, lows, and averages. Concluding the study is an examination of the department's immediate goals and long range plans in the years after 1923. The general conclusion of the study is that the department played a useful role in the development of state roads in Texas.

On Viewing Press Releases of the Texas State AFL-CIO as Rhetorical Genre (open access)

On Viewing Press Releases of the Texas State AFL-CIO as Rhetorical Genre

Previous scholarship on labor rhetoric has concentrated on the impact of declining union membership and contemporary activist strategies on the part of unions. The press release is a common form of communication that organized labor employs in order to reach its publics. This study explores the press releases of the Texas State AFL-CIO to determine to what extent this level of labor discourse meets the criteria of a rhetorical genre. This study employs the methodology for generic criticism laid out by Foss for identifying genres. The study concludes that a genre of labor rhetoric exists and that the genre was used extensively to promote the Texas State AFL-CIO as a socially-conscious and politically motivated organization.

An Analysis of the Accounting System of the Quincy Mining Company: 1846-1900 (open access)

An Analysis of the Accounting System of the Quincy Mining Company: 1846-1900

This historical study examines the evolution of the accounting system of the Quincy Mining Company between 1846 and 1900. The external financial reporting practices and internal accounting procedures of the firm are defined and interpreted in the context of three time periods that portray the formation, growth and maturation of the firm. Each period reflects unique economic and social conditions that are associated with changes in the firm's accounting system. A cross temporal analysis of these changes highlights three factors: the relationship between the accounting system and the labor force, the emergence of accounting as a control mechanism and the diminishing informational content of the firm's annual reports. Primary sources are used to document the perspectives of the Quincy management and to assess the motivations for accounting processes such as internal control, auditing procedures, responsibility centers and other managerial practices. This study addresses the inherent nature of accounting information and its relationship to the economic and social environment of an individual firm in the nineteenth century.

The Information Content of Supplemental Reserve-Based Replacement Measures Relative to that of Historical Cost income and its Cash and Accrual Components of Oil and Gas Producing Companies (open access)

The Information Content of Supplemental Reserve-Based Replacement Measures Relative to that of Historical Cost income and its Cash and Accrual Components of Oil and Gas Producing Companies

This study examined whether three reserve-based quantity replacement measures and three reserve-based value replacement measures have incremental information content beyond that of historical earnings and its cash and accrual components. This study also examined whether the cash and accrual components of earnings have incremental information content beyond that of earnings.

Creation and Characterization of an Escherichia Coli and Pseudomonas Putida Hybrid Aspartate Transcarbamoylase (open access)

Creation and Characterization of an Escherichia Coli and Pseudomonas Putida Hybrid Aspartate Transcarbamoylase

Aspartate transcarbamoylase (ATCase) is encoded by the pyrBI genes in E. coli. Expression of these genes is reduced four-fold by attenuation when grown on uracil. Using plasmid, pRO1727. the pyrB and the pyrBI genes from E. coli were cloned into a P. putida pyrB auxotroph. A recombinant pyrB gene was recovered that encoded a functional hybrid ATCase with a molecular weight of 470 kDa.

Molecular Phylogeny and Evolution of the American Woodrats, Genus Neotoma (Muridae) (open access)

Molecular Phylogeny and Evolution of the American Woodrats, Genus Neotoma (Muridae)

The evolutionary relationships of woodrats (Neotoma) were elulcidated through phylogenetic analyses of mitochondrial DNA restriction site and allozyme data. DNA samples from eleven nominal species from the genus Neotoma and two outgroup taxa, Ototylomys phyttotis and Xenomys nelsoni, were cleaved using a suite of 17 Type II restriction endonucleases. Mitochondrial DNA restriction profiles were visualized following electrophoresis of restriction digests via methods of Southern transfer and hybridization with 32P- and digoxigenin-labeled mtDNA probes. Restriction mapping resulted in the identification of 37 unique mtDNA haplotypes among the woodrat taxa examined. Proteins representing 24 presumptive structural gene loci were examined through starch gel electrophoresis. Binary-coded allozyme data and allozyme frequency data were analyzed using PAUP and FREQPARS, respectively. Phylogenetic analyses of the mtDNA restriction site data incorporated three different character type assumptions: unordered binary characters, Dollo characters, and differentially weighted unordered characters employing the STEPMATRIX option of PAUP. Proposed phylogenies for Neotoma are based on majority-rule consensus trees produced using bootstrap procedures. Phylogenetic analyses of the woodrat data sets revealed a distinct dichotomy among populations of white-throated woodrats (N. albigula) suggesting the presence of cryptic species within that taxon. MtDNA and allozyme data support the specific status of N. devia as distinct …

Nucleotide Sequence Determination, Subcloning, Expression and Characterization of the xy1LT Region of the Pseudomonas putida TOL Plasmid pDK1 (open access)

Nucleotide Sequence Determination, Subcloning, Expression and Characterization of the xy1LT Region of the Pseudomonas putida TOL Plasmid pDK1

The complete nucleotide sequence of the region encoding the DHCDH function of the pDK1 lower operon was determined. DNA analysis has shown the presence of two open reading frames, one gene consisting of 777 nucleotides encoding a polypeptide of 27.85 kDa and another gene of 303 nucleotides encoding a polypeptide of 11.13 kDa. The results of enzymatic expression studies suggest that DHCDH activity is associated only with xy1L. However although the addition of xy1T cell-free extracts to xy1L cell-free extracts does not produce an increase in DHCDH activity, subclones carrying both xy1L and xy1T exhibit 300- 400% more DHCDH activity than subclones carrying only xy1L.
