Accuracy and Efficiency in Computational Chemistry: The Correlation Consistent Composite Approach

Description: One of the central concerns of computational chemistry is that of efficiency (i.e. the development of methodologies which will yield increased accuracy of prediction without requiring additional computational resources – RAM, disk space, computing time). Though the equations of quantum mechanics are known, the solutions to these equations often require a great deal of computing power. This dissertation primarily concerns the theme of improved computational efficiency (i.e. the achievement of g… more

The Adagio of Mahler's Ninth Symphony: A Schenkerian Analysis and Examination of the Farewell Story

Description: Mahler's Ninth Symphony, since its premier in 1912, has sparked much debate about its programmatic meaning. This thesis provides an in-depth analysis of the Adagio and an examination of the controversy of the farewell story. In the process of the analysis I have compared my findings to some of the important authors in Mahler's field such as Vera Micznik, Henry-Louis de La Grange, and Christopher Orlo Lewis. Some of the conclusions are that a closer investigation of the music is necessary and th… more

ADHD Symptomology and Overweight Among College Men

Description: Attention deficit/hyperactivity disorder (ADHD) is a childhood disorder that often persists into adulthood. Among adults, ADHD is highly comorbid with addictive behaviors (e.g., substance abuse and dependence), and depressive disorders. Recently, an association between ADHD and obesity has been reported in the literature; emotional and binge eating may be “addictive behaviors” that contribute to weight gain in this population. The purpose of this study was to test competing models of the hypoth… more

Advancements in Instrumentation for Fourier Transform Microwave Spectroscopy

Description: The efforts of my research have led to the successful construction of several instruments that have helped expand the field of microwave spectroscopy. The classic Balle-Flygare spectrometer has been modified to include two different sets of antenna to operate in the frequency ranges 6-18 GHz and 18-26 GHz, allowing it to function for a large range without having to break vacuum. This modified FTMW instrument houses two low noise amplifiers in the vacuum chamber to allow for the LNAs to be as cl… more

Algebraically Determined Semidirect Products

Description: Let G be a Polish group. We say that G is an algebraically determined Polish group if given any Polish group L and any algebraic isomorphism from L to G, then the algebraic isomorphism is a topological isomorphism. We will prove a general theorem that gives useful sufficient conditions for a semidirect product of two Polish groups to be algebraically determined. This will smooth the way for the proofs for some special groups. For example, let H be a separable Hilbert space and let G be a subset… more

Analysis of Micro Enterprise Clusters in Developing Countries: A Case Study of Toluca, Mexico.

Description: Businesses cluster to achieve agglomeration benefits. However, research in developing countries suggests that the economic environment limits small business’ propensity to benefit from agglomerations. The study examines the location, networking patterns, formal structures and owner characteristics of 1256 micro businesses from ten industries and thirteen sample areas in Toluca, Mexico. First, the thesis analyses whether clustering has a positive impact on the success rates of the surveyed enter… more

Anatomical and Morphological Responses of Cardiospermum Halicacabum L. (Balloon Vine), to Four Levels of Water Availability

Description: C. halicacabum (Sapindaceae) is an invasive plant that is considered a nuisance species in Texas riparian environments. Little is known of the tolerance of C. halicacabum to flooding and drought; however, this information may provide insight into the characteristics that contribute to C. halicacabum purported invasiveness. C. halicacabum seedlings (n = 92) were exposed to one of four levels of water availability (flooded, saturated, intermediate and dry) over six weeks under greenhouse conditio… more

Ancient Musical Ideas Through a Twenty-First Century Lens: An Examination of Tarik O’Regan’s Scattered Rhymes and Its Relationship to Guillaume de Machaut’s Messe de Notre Dame

Description: British composer Tarik Hamilton O’Regan (b. 1978, London) is earning a reputation as an important composer of today. The innovative works of O’Regan are entering the spectrum of professional, educational, and community performing organizations across the United States and Europe. Scattered Rhymes’ intricate melodic, harmonic, and rhythmic relationships with Messe de Notre Dame by Guillaume de Machaut (c.1300-1377) make an examination and comparison of the two works significant.

Application of FTIR for Quantification of Alkali in Cement

Description: Alkali-silica reaction (ASR) in cement is a major contributor to failure of cement structures around the world, causing increased repair costs and possible rebuild expenses. Alkali levels are indicative of the potential for ASR and are therefore measured and quantified. A linear correlation relating cement alkali concentration measured by X-ray fluorescence spectroscopy (XRF) and peak ratio measured by Fourier transform infrared spectroscopy (FTIR) is developed. Regression analysis of plots cor… more

Arithmetic Computations and Memory Management Using a Binary Tree Encoding af Natural Numbers

Description: Two applications of a binary tree data type based on a simple pairing function (a bijection between natural numbers and pairs of natural numbers) are explored. First, the tree is used to encode natural numbers, and algorithms that perform basic arithmetic computations are presented along with formal proofs of their correctness. Second, using this "canonical" representation as a base type, algorithms for encoding and decoding additional isomorphic data types of other mathematical constructs (set… more

The Art-Union and Photography, 1839-1854: The First Fifteen Years of Critical Engagement between Two Cultural Icons of Nineteenth-Century Britain

Description: This study analyzes how the Art-Union, a British journal interested only in the fine arts, approached photography between 1839 and 1854. It is informed by Karl Marx’s materialism-informed commodity fetishism, Gerry Beegan’s conception of knowingness, Benedict Anderson’s imagined community, and an art critical discourse that was defined by Roger de Piles and Joshua Reynolds. The individual chapters are each sites in which to examine these multiple theoretical approaches to the journal’s and phot… more

Assessment and Treatment of Multiple Topographies of Self-injury Maintained by Separate Reinforcement Contingencies

Description: Functional analysis procedures were used to assess and treat multiple topographies of self-injurious behavior exhibited by an individual. An experimental functional analysis indicated that one topography, hand biting, appeared to be maintained by social positive reinforcement in the form of delivery of tangible items. The analysis also provided evidence that a second form of self-injury, skin picking, was automatically reinforced. To treat positively reinforced hand biting, access to a preferre… more

Assessment of Feigning with the Trauma Symptom Inventory: Development and Validation of new Validity Scales with Severely Traumatized Patients

Description: Currently, only the TSI assesses complex traumatic reactions and patient response styles. However, its feigning scale, ATR, uses a flawed detection strategy and is potentially confounded by experiences of complex PTSD. As a consequence, clinicians using the TSI to evaluate severely traumatized patients have no useful method for discriminating genuine and feigned responding. Several detection strategies have demonstrated utility within evaluations of feigned trauma including the assessment of ra… more

Assessment of Transportation Emissions for Ferrous Scrap Exports from the United States: Activity-Based Maritime Emissions Model and Theoretical Inland Transportation Model.

Description: Industrial ecology is a field of study that encourages the use of closed-loop material cycles to achieve sustainability. Loop closing requires the movement of materials over space, and has long been practiced in the iron and steel industry. Iron and steel (ferrous) scrap generated in the U.S. is increasingly exported to countries in Asia, lengthening the transportation distance associated with closing the loop on the iron and steel life cycle. In order to understand the environmental cost of… more
