Federalism and Civil Conflict: the Missing Link?

Description: This thesis investigates federalism and civil conflict. Past work linking federalism and civil conflict has investigated the factors that pacify or aggravate conflict, but most such studies have examined the effect of decentralization on conflict onset, as opposed to the form federalism takes (such as congruent vs incongruent forms, for example). I collect data on civil conflict, the institutional characteristics of federalist states and fiscal decentralization. My theoretical expectations are … more

Female Orgasm From Intercourse: Importance, Partner Characteristics, and Health

Description: Previous research indicates that women prefer orgasms triggered by penile-vaginal intercourse (PVI) as compared to those triggered by direct manual stimulation of the clitoris. However, for reasons that are not well understood, most women are unable to reach PVI orgasms as often as they desire. In addition, it is unclear why many women prefer PVI orgasms to those triggered by direct clitoral stimulation. This study developed a more precise measure of PVI orgasm frequency and evaluated key pr… more

From Ritual to Art in the Puritan Music of Colonial New England: the Anthems of William Billings

Description: The manner in which Billings’s music contrasts with the Puritan musical ideal clearly demonstrates his role in the transition from ritual to art in the music of eighteenth-century New England. The tenets of Puritan worship included the restriction that music should serve primarily as a form of communal prayer for the congregation and in a secondary capacity to assist in biblical instruction. Billings’s stylistic independence from Puritan orthodoxy began with a differing ideology concerning th… more

Harmony Or Discord: Disordered Eating and Personality Traits of College Music Majors

Description: Personality traits, such as neuroticism, perfectionism, and a narrow self-concept have been identified as risk factors for eating disorders or have been found at higher rates in those with eating disorders (e.g., Brannan & Petrie, 2008; Cash & Deagle, 1997; Cervera et al., 2003). Musicians exhibit many of these personality traits associated with eating disorders (e.g., Kemp, 1981), however eating disorder prevalence has not been studied in musicians. The present study examined the prevalence … more

Hormonal Response to Free Weight and Machine Weight Resistance Exercise

Description: No study has examined the effect of exercise modality (free weight vs. machine weight) on the acute hormonal response using similar multi-joint exercises. The purpose of this investigation was to examine the effect of resistance exercise modality on acute hormonal responses by comparing the squat and leg press which are multi-joint, and similar in action and lower-body muscle involvement. Ten resistance trained men (21-31 y, 24.7 ± 2.9 y, 179 ± 7 cm, 84.2 ± 10.5 kg) participated in the study.… more

The Hostess

Description: The following is a critical preface and portion of a novel-in-progress produced during my master's program in creative writing at the University of North Texas. The preface analyzes the way time and point of view work together to create or determine structure in fiction, as well as provide added meaning. In order to explore these topics I focus on two novels, Joan Didion’s Play It as It Lays and Jennifer Egan’s A Visit from the Goon Squad, and speak to how these elements have influenced my own … more

Hypoxia and the Development of Endothermic Capacity in Chickens (Gallus Gallus)

Description: Adult chickens employ endothermy – internal generation of heat that maintains a constant body temperature (Tb). Prior to hatching, chicken embryos are ectothermic - controlling Tb by external heat sources. Upon hatching, the hatchling transitions from an ectotherm to an endotherm that has been shown to be delayed by hypoxia. In this study, whole animal oxygen consumption () and liver, heart, and skeletal muscle citrate synthase activity (CSA) and were measured during this transition to endothe… more

The Impact of Quality on Customer Behavioral Intentions Based on the Consumer Decision Making Process As Applied in E-commerce

Description: Perceived quality in the context of e-commerce was defined and examined in numerous studies, but, to date, there are no consistent definitions and measurement scales. Instruments that measure quality in e-commerce industries primarily focus on website quality or service quality during the transaction and delivery phases. Even though some scholars have proposed instruments from different perspectives, these scales do not fully evaluate the level of quality perceived by customers during the entir… more

The Impact of the Development of the Fortepiano on the Repertoire Composed for It From 1760–1860

Description: The relationship between piano manufacturer and composer is interactive, and consequently both compositions and performance styles evolved organically due to this relationship. Early on, the instrument had more influence on the composer, whereas with the instrument’s establishment, composers began to exert more influence on the subsequent development of the instrument through their requests of manufacturers. The relationship between pianist-composers and manufacturers is important for pianists… more

An Interactive Tool to Investigate the Inference Performance of Network Dynamics From Data

Description: Network structure plays a significant role in determining the performance of network inference tasks. An interactive tool to study the dependence of network topology on estimation performance was developed. The tool allows end-users to easily create and modify network structures and observe the performance of pole estimation measured by Cramer-Rao bounds. The tool also automatically suggests the best measurement locations to maximize estimation performance, and thus finds its broad applications… more

Irony, Humor, and Ontological Relationality in Literature

Description: The purpose of this dissertation is to investigate ontological relationality in literary theory and criticism by critically reflecting on modern theories of literature and by practically examining the literary texts of Geoffrey Chaucer, William Shakespeare, and Oscar Wilde. Traditional studies of literary texts have been oriented toward interpretative or hermeneutic methodologies, focusing on an independent and individual subject in literature. Instead, I explore how relational ontology uncover… more

Jacques Ibert: an Analytical Study of Three Movements From Histoires

Description: Although many biographical studies are available on Jacques Ibert, few contain significant analytical commentary. In this study I examine three movements from Ibert’s Histoires for piano which was composed between 1920 and 1921 and was premiered in 1923. The three movements are “La menuese de tortues d’or,” “Le petit âne blanc,” and “La marchande d’eau fraîche.” I primarily use Schenkerian analysis to identify characteristics of Ibert’s compositional language. Significant aspects of impressio… more

Johann Nepomuk Hummel’s Transcriptions of Beethoven´s Symphony No 2, Op 36: a Comparison of the Solo Piano and the Piano Quartet Versions

Description: Johann Nepomuk Hummel was a noted Austrian composer and piano virtuoso who not only wrote substantially for the instrument, but also transcribed a series of important orchestral pieces. Among them are two transcriptions of Beethoven’s Symphony No. 2 in D Major, Op. 36- the first a version for piano solo and the second a work for piano quartet, with flute substituting for the traditional viola part. This study will examine Hummel’s treatment of the symphony in both transcriptions, looking at a v… more

José Antonio Gómez´s Versos Para Órgano (Section I): a Practical Guide for Performance

Description: José Antonio Gómez is an important figure in Mexican music history and his works are considered representative of the beginning of Mexico´s Independent era. Some musicians are familiar with Gómez´s choral output but his organ music is rarely considered. Due to the lack of an edition of Gómez´s Versets for Organ, a practical guide was found needed to aid its performance. This study is based on performance, analysis, and direct work on the only known source for it. The first chapter, Introducti… more

Kleinian Groups in Hilbert Spaces

Description: The theory of discrete groups acting on finite dimensional Euclidean open balls by hyperbolic isometries was borne around the end of 19th century within the works of Fuchs, Klein and Poincaré. We develop the theory of discrete groups acting by hyperbolic isometries on the open unit ball of an infinite dimensional separable Hilbert space. We present our investigations on the geometry of limit sets at the sphere at infinity with an attempt to highlight the differences between the finite and infin… more
