The evaluation, development, and application of the correlation consistent basis sets.

Description: Employing correlation consistent basis sets coupled with electronic structure methods has enabled accurate predictions of chemical properties for second- and third-row main group and transition metal molecular species. For third-row (Ga-Kr) molecules, the performance of the correlation consistent basis sets (cc-pVnZ, n=D, T, Q, 5) for computing energetic (e.g., atomization energies, ionization energies, electron and proton affinities) and structural properties using the ab initio coupled cluster method including single, double, and quasiperturbative triple excitations [CCSD(T)] and the B3LYP density functional method was examined. The impact of relativistic corrections on these molecular properties was determined utilizing the Douglas-Kroll (cc-pVnZ-DK) and pseudopotential (cc-pVnZ-PP) forms of the correlation consistent basis sets. This work was extended to the characterization of molecular properties of novel chemically bonded krypton species, including HKrCl, FKrCF3, FKrSiF3, FKrGeF3, FKrCCF, and FKrCCKrF, and provided the first evidence of krypton bonding to germanium and the first di-krypton system. For second-row (Al-Ar) species, the construction of the core-valence correlation consistent basis sets, cc-pCVnZ was reexamined, and a revised series, cc-pCV(n+d)Z, was developed as a complement to the augmented tight-d valence series, cc-pV(n+d)Z. Benchmark calculations were performed to show the utility of these new sets for second-row species. Finally, the correlation consistent basis sets were used to study the structural and spectroscopic properties of Au(CO)Cl, providing conclusive evidence that luminescence in the solid-state can be attributed to oligomeric species rather than to the monomer.

An Evaluation Model for Identifying Lewisville and San Angelo, Texas, as Senior Ready Communities

Description: This research portrays a paradigm for the assessment of aging services to support populations aging in place. The dissertation was designed to establish a model to identify and evaluate senior ready communities. Area specific social programs and services are identified. In order to meet the growing needs of aging populations, the dynamic representation of existing services and the need for services that could be developed in certain communities require reevaluation in current planning, restructuring, and/or community development.

Evaluation of a Common Carp (Cyprinus carpio L.) Exclusion and Trapping Device for Use in Aquatic Plant Founder Colony Establishment

Description: The focus of this study was to design and evaluate a trapping system that would reduce populations of common carp within water bodies in conjunction with establishment of native aquatic macrophytes founder colonies. A pond study and field study were conducted. A pond study was performed at the Lewisville Aquatic Ecosystem Research Facility, located in Lewisville, Texas, followed by a field study within a constructed wetland located in southern Dallas, Texas. For the pond study, twelve funnel traps were constructed (four reps of each type: control, dual-walled and ring cage). Two anti-escape devices were tested with funnels including steel fingers and hinged flaps. Ring cage and dual-walled treatments were planted using native pondweeds, while controls were left unplanted (additional bait and a drift fence scenarios were also tested). Common carp were introduced into the study pond. Chi-square statistical analyses were utilized and showed ring cage treatments using fingers as well as the use of a drift fence to be most effective. Following completion of the pond study, the two most effective treatments (controls and ring cages) were tested within the Dallas, Texas wetland; no carp were caught during the field test.

Evaluation of a Constructed Wetland to Reduce Toxicity from Diazinon at the Pecan Creek Wastewater Treatment Plant, Denton, TX

Description: The City of Denton Pecan Creek Wastewater Treatment Facility has periodically failed effluent toxicity testing. A Toxicity Identification Evaluation has determined that Diazinon in the effluent is contributing to the observed toxicity. Chlorpyrifos is also implicated as a factor. The City of Denton constructed a half acre experimental wetland to remove Diazinon related toxicity. Results from spiking and microcosm experiments indicate that the wetland can reduce the Diazinon.

Evaluation of a Master of Divinity Program in a Theological Seminary

Description: The objective of this research project was to evaluate the effectiveness of the M.Div. program of Alliance Bible Seminary, Hong Kong. The research was designed for evaluation based solely upon the perceptions of the participant (graduate). The research identified and described the graduates enrolled, assessed perceived career development and attainment, and measured the degree of satisfaction experienced by the graduates who have matriculated from the degree program. A questionnaire was mailed to obtain the necessary data from the graduates of the M.Div. program of Alliance Bible Seminary. The questionnaire which was used was adapted from a previously used one used in the study of graduate educational programs. It has been tested in two other previous studies and was deemed effective. In order to verify its effectiveness in the Eastern context, a pilot test was conducted before the formal research, and the adapted questionnaire was found effective. Responses to the questionnaire were coded and the SPSS system was used to analyze the data. Tables and figures were constructed showing frequencies and significant differences where they occurred. Generally, the graduates at Alliance Bible Seminary were very satisfied with their educational experiences. Both males and females indicated that they would choose the same path again, and would recommend the program to others. The graduates were having full-time employment in the field of Christian ministry, and were positively attaining their career goals. The steps leading to the degree at Alliance Bible Seminary were perceived as very helpful and useful, not just the course work and independent reading, but also extre-curricular activities such as voluntary work on campus, Student Evangelistic Band, and interaction with faculty. Some aspects of the program need improvement and consolidation, such as freshmen advising in the majors, course work in the core, quality of instruction, varieties of course offered, and access ...

Evaluation of a Training Package for Teaching Social Skills in an Inclusionary Preschool Environment

Description: Effective training procedures are necessary when teaching behavior analytic techniques because the techniques are so complex and precise; and there is a correlation between the changed skills in the trainees to be beneficial to the client. Instructors who may previously exhibit effective teaching techniques in a one-to-one setting may not exhibit those techniques in an inclusive setting. This study examines the effects of a training package and an instruction on the performance of experienced instructors, and desired responding from both preschool-aged children with autism and typically developing peers. The training took place with 3 triads of one instructor, one child with autism, and one peer in a center-based inclusionary preschool. Instructor skills targeted were prompt and consequence delivery for the target social skills, getting attention and responding to peers. Corroborative data on children's responding were obtained.

Evaluation of Adsorption and Microcoulometric Methods for Determination of Halogenated Organic Compounds in Water

Description: Two adsorption/microcoulometric methods have been investigated for total organic halogen (TOX) in water. TOX, a proposed water-quality parameter, is a rapid, surrogate method to detect halides microcoulometrically and does not require compound identification before water quality can be judged. An XAD resin is used to concentrate organic halides that are eluted by a two-step, two-solvent procedure, followed by analysis using :chromatography or pyrolysis to convert organic halides to halide. In the granular activated carbon (GAC) method, the entire GAC-organic halide sample is pyrolyzed. TOX measurements of model compounds are comparable by both methods, but GAC was found to be superior to XAD for adsorption of chlorinated humics in drinking water and chlorinated lake water.
