Red Dresses for Funerals contains a scholarly preface concerning the nature of factuality versus credibility in the writing of fiction. Four original short stories are included in this thesis. "A Night With Lawrence Welk" explores the relationship between a patient and student intern psychologist. "Red Dresses for Funerals" is about a wedding that plays a significant role in a variety of the characters' lives. "Trace Elements" is the only story involving young children. "Trace Elements" explores the beginning of understanding of some of the grimmer aspects of reality. "Expectations, Great and Otherwise" addresses the issue of denial. These stories are linked by their setting, a small town in Texas.

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.

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.

To further understand the ATCase/DHOase bifunctional complex formed in Streptomyces, the genes encoding these and other pyrimidine enzymes were identified and characterized. Polymerase chain reaction (PCR) was utilized in this effort. Primers were constructed by selecting conserved regions of pyrimidine genes from known gene and protein sequences of a wide variety of organisms. These sequences were then optimized to Streptomyces codon usage. PCR products were obtained from internal sites within pyrimidine genes and also from primer combinations of different genes. The size, orientation, and partial sequence of the resulting products shows that Streptomyces has a gene organization of pyrR followed by pyrB, pyrC, carA, carB, and pyrF in an operon similar to that found in other Gram-positive bacteria.

The phylogenetics of eight species of the Peromyscus truei and P. boylii species groups from 15 populations were analyzed based on mitochondrial DNA sequence differentiation, using 13 hexanucleotide specific restriction enzymes. P. difficilis, P. nasutus, and P. attwateri were found to be members of the same clade. P. leucopus was not found to be closely related to any of the species of the boylii or truei species groups. Phylogenetic interpretations for the remaining species differed based on Wagner and Dollo parsimony analyses. P. true appears to be most closely related to P. gratus based on Wagner parsimony and the phenetic analysis, while the relationship of P. gratus to other species could not be resolved based on Dollo parsimony.

Cassette systems for creating intergeneric hybrid ATCases were constructed. An MluI restriction enzyme site was introduced at the carbamoylphosphate binding site within the pyrB genes of both Pseudomonas putida and Escherichia coli. Two hybrids, E. coli pyrB polar domain fused with P. putida pyrB equatorial domain and P. putida pyrB polar domain fused with E. coli pyrB equatorial domain, are possible. The intergeneric E. coli-P. putida hybrid pyrB gene was constructed and found to encode an active ATCase which complemented an E. coli Pyr- strain. These hybrids are useful for kinetic and expression studies of ATCase in E. coli.

In the United States, biodiversity impact assessment has historically received little attention. Responding in 1993, the Council on Environmental Quality (CEQ) released guidelines on incorporating biodiversity into environmental impact assessment under the National Environmental Policy Act of 1969. The objectives of the study here were to identify the level of documentation of biodiversity impact assessment in sample Environmental Impact Statements (EISs); identify whether in the years following the release of 1993 CEQ guidelines any significant changes have taken place in assessment of biodiversity; identify deficiencies, and if the need exists, formulate appropriate recommendations and approaches for addressing biodiversity in EISs. The study involved a systematic review of 30 EISs published since the release of CEQ guidelines, and five EISs published prior to it. The review involved answering a series of standard questions, which attempted to ascertain the level of biodiversity impacts included in each impact statement. Trends in approaches to biodiversity impact assessment were investigated and deficiencies summarized. The analysis resulted in a series of recommendations for improving the manner in which biodiversity impact assessment can be approached.

This study focuses on the development of water resources in the Trinity River basin for navigation, flood control, water supply, recreation, and allied purposes. Special emphasis is given to the development of the upper Trinity River basin through the influence of community leaders in Dallas and Fort Worth. A desire harbored for generations by upper basin residents for creating a navigable waterway on the Trinity River coalesced in the twentieth century into a well organized movement for all facets of water resources development. Sources include correspondence, speeches, and promotional materials of civic leaders, politicians, and other citizens, as well as works by the United States Army Corps of Engineers.

Lack of sufficient water for irrigation is a major problem in and around the valleys surrounding the town of Aiquile, Cochabamba Bolivia. In addition, much of the region is undergoing desertification compounded by drought, deforestation, bad traditional agricultural practices, over grazing and a "torrential" rainfall pattern leading to severe soil erosion and low agricultural production. Between 1992 and 1994, the author constructed a network of 24 small, mostly rainfed farm ponds to increase agricultural production and alleviate soil erosion and land-use problems by improving cover conditions. A 5-year post-impoundment analysis was carried out in 1998. The analysis examined current pond conditions, design criteria, irrigation water / crop production increases and the alleviation of land-use problems. Current pond conditions fell into four distinct categories with only 25 percent of the ponds being deemed as "functioning well." The project increased irrigation in the region and improved cover conditions in 66 percent of the pond sites.

Carbonic anhydrase is a ubiquitous zinc-metalloenzyme that catalyzes the interconversion of carbon dioxide and carbonate and has been found to play a wide range of roles in animals, plants and bacteria. Cotton genomic and cDNA libraries were screened for the plastidial isoform of carbonic anhydrase. The nucleotide sequences of two 1.2 Kb partial cDNA clones were determined. These clones exhibit high homology to carbonic anhydrases from other dicot plants and possess all the expected peptide motifs. For example, serine and threonine rich chloroplastic targeting peptide and conserved zinc binding residues are both present. These clones were utilized to isolate two carbonic anhydrase genes that were shown to encode different isoforms by PCR and RFLP analysis.

Earl suffers from a guilty obsession with a monster catfish. Eddie Klomp searches dog tracks for the ghosts of his lost childhood. Mike Towns is a hopeless blues musician who loses everything he cares for. Blair Evans learns to love a pesky wart. Americana becomes confused with the difference between knowledge and sex. Do Not Eat Fish from These Waters And Other Stories is a collection of short stories that explores the strange and often defeated lives of these Southern characters (and one from the point-of-view of a feral hog). Each man, woman, and hog flails through a period of potential metamorphosis trying to find some sort of meaning and worth in the past, present and future. Not all of these characters succeed.

Nutrients are of critical concern in water quality assessment. The development of empirical models to estimate mean nutrient concentrations, based on satellite derived land use, could aid water resource managers. Models using land use acreages outperformed those using percentages, and discrete urban land uses were superior to lumped urban. Regressions of the combinations of two, three and four of the eight possible land use variables were investigated. Sensitivity analyses, with one stream deleted each series, identified robust combinations of variables at each level. Although uncertainty exists regarding the final regression coefficients, five of the six actual measured nitrate and total phosphorus mean concentrations were within the 95 percent confidence limits.

The following is a complete syllabus for a college level genetics course. The syllabus contains lecture outlines and notes for each chapter, along with a list of transparencies needed. The quizzes and exams are prepared and placed at the beginning of the syllabus. The beginning of the course will consist of a lecture to introduce the students to the basics of genetics, followed by many applications of genetics. The process of cell division will be mastered by the students, as well as Mendelian genetics, quantitative genetics, chromosome mapping, and inheritance. The replication, synthesis, and organization of DNA are also discussed within the lectures. The final topics that will be covered using this syllabus are genetics of cancer and immunology and population genetics. These topics are essential for a detailed genetics course. The syllabus is written in great detail, and will require a full semester to be completed. The book used in association with this syllabus is Essentials of Genetics by William S. Klug and Michael R. Cummings.
