Relationships Among Self-esteem, Psychological and Cognitive Flexibility, and Psychological Symptomatology

Description: Previous findings on the relationship between self-esteem and psychological outcomes are inconsistent. Therefore it appears that self-esteem, while related to crucial variables, does not provide a clear, direct, and comprehensive prediction of psychological symptoms. Thus, it was hypothesized that the relationship between self-esteem and symptomatology would be moderated by broader measures of how one interacts with emotional and cognitive stimuli.The purpose of this study was to examine the in… more

The Creation of a Performance Edition of Gustav Mahler's Lieder Und Gesänge Aus Der Jungendzeit and Its Role in Bass Tuba Pedagogy

Description: When the tubist is first introduced to the bass tuba, Mahler's songs can be used as effective solo material. Through transcription, practice, and performance of art songs, novice bass tubists focus primarily on fundamental musical components such as tone quality, intonation, breathing, and musicianship. By identifying deficiencies in the current solo repertoire as related to the early stages of development on the bass tuba, I intend to address the need for more solo works through the transcri… more

A Comparative Analysis of Web-based Machine Translation Quality: English to French and French to English

Description: This study offers a partial reduplication of a 2006 study by Williams, which focused primarily on the analysis of the quality of translation produced by online software, namely Yahoo!® Babelfish, Freetranslation.com, and Google Translate. Since the data for the study by Williams were collected in 2004 and the data for present study in 2012, this gives a lapse of eight years for a diachronic analysis of the differences in quality of the translations provided by these online services. At the time… more

The Enemy of My Enemy Is What, Exactly? the British Flanders Expedition of 1793 and Coalition Diplomacy

Description: The British entered the War of the First Coalition against Revolutionary France in 1793 diplomatically isolated and militarily unprepared for a major war. Nonetheless, a French attack on the Dutch Republic in February 1793 forced the British to dispatch a small expeditionary force to defend their ally. Throughout the Flanders campaign of 1793, the British expeditionary force served London as a tool to end British isolation and enlist Austrian commitment to securing British war objectives. Th… 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

Characterization of Arthrobacter Globiformis Aspartate Transcarbamylase Concentrations of Substrates

Description: This thesis consists of one major section with two subsections. The first subsection investigates the activity of Arthrobacter globiformis aspartate transcarbamylase's specific activity with increasing concentrations of the enzyme's substrate. Dihydroorotase (DHOase) activity was also measured with increasing concentrations of the substrate dihydroorotate. The second subsection collected data in order to classify the enzyme, resulting in a classification into the category of class A ATCases … more

Criticality in Cooperative Systems

Description: Cooperative behavior arises from the interactions of single units that globally produce a complex dynamics in which the system acts as a whole. As an archetype I refer to a flock of birds. As a result of cooperation the whole flock gets special abilities that the single individuals would not have if they were alone. This research work led to the discovery that the function of a flock, and more in general, that of cooperative systems, surprisingly rests on the occurrence of organizational collap… more

Ecological Forms of Life: Wittgenstein and Ecolinguistics

Description: The present philosophical literature on philosopher Ludwig Wittgenstein tends to either stagnate by focusing upon issues particular to Wittgenstein's philosophy or expand the boundaries of Wittgenstein's thought to shed light onto other areas of study. One area that has largely been ignored is the realm of environmental philosophy. I prepare the way for a solution to this by first arguing that Wittgenstein's later philosophy of language shows 'proto-ecolinguistic' concerns, sharing much in co… more

Solid Lubrication Mechanisms in Laser Deposited Nickel-titanium-carbon Metal Matrix Composites

Description: A Ni/TiC/C metal matrix composite (MMC) has been processed using the laser engineered net shaping (LENS) process from commercially available powders with a Ni-3Ti-20C (atomic %) composition. This processing route produces the in-situ formation of homogeneously distributed eutectic and primary titanium carbide and graphite precipitates throughout the Ni matrix. The composite exhibits promising tribological properties when tested in dry sliding conditions with a low steady state coefficient of fr… more

Real Analyticity of Hausdorff Dimension of Disconnected Julia Sets of Cubic Parabolic Polynomials

Description: Consider a family of cubic parabolic polynomials given by for non-zero complex parameters such that for each the polynomial is a parabolic polynomial, that is, the polynomial has a parabolic fixed point and the Julia set of , denoted by , does not contain any critical points of . We also assumed that for each , one finite critical point of the polynomial escapes to the super-attracting fixed point infinity. So, the Julia sets are disconnected. The concern about the family is that the… more

British Labour Government Policy in Iraq, 1945-1950

Description: Britain during the Labour government's administration took a major step toward developing Iraq primarily due to the decision of Ernest Bevin, the Foreign Minister, to start a new British policy toward the Iraqi regimes that would increase the British influence in the area. This led to Bevin's strategy of depending on guiding the Iraqi regime to make economic and political reforms that would lead to social justice.

Spatio-temporal Variation of Nitrate Levels in Groundwater in Texas, 1970 to 2010

Description: This study looks at spatial variation of groundwater nitrate in Texas and its fluctuations at 10 year increments using data from the Texas Water Development Board. While groundwater nitrate increased in the Ogallala and Seymour aquifers across the time period, the overall rate in Texas appears to be declining as time progresses. However, the available data is limited. Findings show that a much more targeted, knowledge based strategy for sampling would not only reduce the cost of water qualit… more

Deciphering the details of RNA aminoglycoside interactions: from atomistic models to biotechnological applications

Description: A detailed study was done of the neomycin-B RNA aptamer for determining its selectivity and binding ability to both neomycin– and kanamycin-class aminoglycosides. A novel method to increase drug concentrations in cells for more efficiently killing is described. To test the method, a bacterial model system was adopted and several small RNA molecules interacting with aminoglycosides were cloned downstream of T7 RNA polymerase promoter in an expression vector. Then, the growth analysis of E. coli … more
