Interfacial Electrochemistry of Copper and Spectro-Electrochemical Characterization of Oxygen Reduction Reaction

Description: The first part of this dissertation highlights the contents of the electrochemical characterization of Cu and its electroplating on Ru-based substrates. The growth of Ru native oxide does diminish the efficiency of Cu plating on Ru surface. However, the electrochemical formed irreversible Ru hydrate dioxide (RuOxHy) shows better coverage of Cu UPD. The conductive Ru oxides are directly plateable liner materials as potential diffusion barriers for the IC fabrication. The part II of this dissertation demonstrates the development of a new rapid corrosion screening methodology for effective characterization Cu bimetallic corrosion in CMP and post-CMP environments. The corrosion inhibitors and antioxidants were studied in this dissertation. In part III, a new SEC methodology was developed to study the ORR catalysts. This novel SEC cell can offer cheap, rapid optical screening results, which helps the efficient development of a better ORR catalyst. Also, the SEC method is capable for identifying the poisoning of electrocatalysts. Our data show that the RuOxHy processes several outstanding properties of ORR such as high tolerance of sulfation, high kinetic current limitation and low percentage of hydrogen peroxide.

The Klezmer Influence in Paul Schoenfield’s Klezmer Rondos

Description: Paul Schoenfield’s Klezmer Rondos is a work for flute, male vocalist, and orchestra revised in 1994 according to the score given to me by the composer. A review of current research in klezmer heritage music is the starting point to place Klezmer Rondos in the context of art music infused with klezmer flavor. Klezmer music can be defined as the instrumental folk music of Eastern European Jews, however because of its adaptability and quality of assimilating other cultures within it, this heritage music is constantly in flux. By looking at the research in this field, I describe how the sound of klezmer music has evolved and how popular notions have been formed. The body of this research explores the main musical aspects of Klezmer Rondos that can be tied to the klezmer tradition: scales and thematic materials, improvisatory elements, ornamentation, and instrumentation. Klezmer Rondos moves beyond a simple arrangement of vernacular music for orchestra; it is a fusion of contemporary art music with the elements of klezmer style.

Mythic Archaeologies: The Impact of Visual Culture on the Art and Identity of Four Hopi Artists

Description: This qualitative critical ethnography examines how visual culture impacted the identity and art of four Hopi artists. Sources of data included a personal journal, artists’ interviews, group discussion, art work interpretations, and historical research of Hopi art, visual culture, and issues of native identity. In particular, my analysis focused on issues of power / knowledge relationships, identity construction, and the artist as co-constructor of culture through personal narratives. Implications for art education centered on the concept of storytelling through mythic archaeology situated in identities of past, present, and future.

Patronage, Connoisseurship and Antiquarianism in Georgian England: The Fitzwilliam Music Collection (1763-1815)

Description: In eighteenth-century Britain, many aristocrats studied music, participated as amateurs in musical clubs, and patronized London’s burgeoning concert life. Richard Fitzwilliam, Seventh Viscount Fitzwilliam of Merrion and Thorncastle (1745-1816), was one such patron and amateur. Fitzwilliam shaped his activities – participation, patronage, and collecting – in a unique way that illustrates his specialized tastes and interests. While as an amateur musician he sang in the Noblemen’s and Gentlemen’s Catch Club (the premiere social club dedicated to musical performance), he rose to the highest level of patronage by spearheading the Handel Commemoration Festival of 1784 and serving for many years as a Director of the Concert of Antient Music, the most prestigious concert series in Georgian Britain. His lasting legacy, however, was his bequest to Cambridge University of his extensive collection of art, books and music, as well as sufficient funds to establish the Fitzwilliam Museum. At the time of his death, Fitzwilliam’s collection of music was the best in the land, save that in the Royal Library. Thus, his collection is ideally suited for examination as proof of his activities, taste and connoisseurship. Moreover, the music in Fitzwilliam’s collection shows his participation in the contemporary musicological debate, evidenced by his advocacy for ancient music, his agreement with the views of Charles Avison and his support for the music of Domenico Scarlatti. On one side of this debate were proponents of learned, ancient music, such as Fitzwilliam and Avison, whose Essay on Musical Expression of 1752 was a milestone in musical criticism. On the other side of the discussion were advocates for the more modern, “classical” style and genres, led by historian Charles Burney.

“Campaigns Replete with Instruction”: Garnet Wolseley’s Civil War Observations and Their Effect on British Senior Staff College Training Prior to the Great War

Description: This thesis addresses the importance of the American Civil War to nineteenth-century European military education, and its influence on British staff officer training prior to World War I. It focuses on Garnet Wolseley, a Civil War observer who eventually became Commander in Chief of the Forces of the British Army. In that position, he continued to write about the war he had observed a quarter-century earlier, and was instrumental in according the Civil War a key role in officer training. Indeed, he placed Stonewall Jackson historian G.F.R. Henderson in a key military professorship. The thesis examines Wolseley’s career and writings, as well as the extent to which the Civil War was studied at the Senior Staff College, in Camberly, after Wolseley’s influence had waned. Analysis of the curriculum from the College archives demonstrates that study of the Civil War diminished rapidly in the ten years prior to World War I.

An Exploration of the Titrating-Delay Match-to-Sample Procedure with Pigeons

Description: The delayed matching‐to‐sample (DMTS) procedure involves the insertion of a delay between the offset of a sample stimulus and the onset of an array of comparison stimuli; one of which is designated as the “correct” match for the sample on each trial. The procedure has served as the base preparation in which the effects of environmental variables on short‐term remembering and is, in many ways, responsible for a refined understanding of the phenomenon. Despite its utility, however, there are a few problems with the DMTS procedure – first, the procedure doesn’t adjust for individual differences and second, the conventional dependent measure, percent of correct trials, is not as sensitive as one might like. The titrating-delay matching to sample (TDMTS) procedure is a variant of the DMTS procedure in which the delays between sample and comparison are adjusted as a function of the subject’s performance. Stable measures of adjusted delay are not only sensitive measures of the performance of interest but they are also automatically tuned to differences across individuals. The study reported here continues our efforts to understand the dynamics of the TDMTS procedure so that it can be used to ask important questions related to short‐term remembering.

Energy Usage While Maintaining Thermal Comfort : A Case Study of a UNT Dormitory

Description: Campus dormitories for the University of North Texas house over 5500 students per year; each one of them requires certain comfortable living conditions while they live there. There is an inherit amount of money required in order to achieve minimal comfort levels; the cost is mostly natural gas for water and room heating and electricity for cooling, lighting and peripherals. The US Department of Energy has developed several programs to aid in performing energy simulations to help those interested design more cost effective building designs. Energy-10 is such a program that allows users to conduct whole house evaluations by reviewing and altering a few parameters such as building materials, solar heating, energy efficient windows etc. The idea of this project was to recreate a campus dormitory and try to emulate existent energy consumption then try to find ways of lowering that usage while maintaining a high level of personal comfort.

Terror Management Theory and Body Image

Description: Research has not explicitly examined the link between key components of terror management theory (TMT) and body image without the use of mortality salience. This project explored the link between cultural worldview, self-esteem, body image, and death anxiety. Multiple measures were used to create a structural equation model examining relationships between body image and death anxiety as mediated by body image in the context of TMT. The proposed model did not fit the data. Minor modifications were made to the model keeping within the proposed theoretical perspective. In the modified model the relationships between cultural worldview and death anxiety as mediated by body image were either non-existent or weak. Hierarchical regression analyses did suggest that some aspects of body image indeed did predict some, but not all dimension of death anxiety in this sample of young adults.

Biodiversity Loss, the Motivation Problem, and the Future of Conservation Education in the United States

Description: The purpose of this dissertation is to make sense of two sets of reactions. On the one hand, Americans can barely lift a finger to help threatened and endangered species while on the other, they routinely come to the aid of human victims of disaster. I argue that in contrast to cases of human tragedy, for the biodiversity crisis conservationists are faced not only with the familiar yet arduous task of motivating the American public to care for living other-than-humans, but they are also saddled with having to overcome the motivation problem of future ethics. The motivation problem consists in eliminating or bridging a motivational gap that lies between knowledge of the effects of our actions on future generations and action taken based upon such knowledge. The gap exists because motives that typically move people to action are either ineffective or unavailable. What is more, the gap influences not only our ability to care for future humans, but it affects our ability to care for future other-than-humans as well. Biodiversity loss is in fact a subset of the problem of future generations, an identification hitherto little appreciated. I argue that conservationists can overcome the motivational gap not by appealing directly to the value of species or biodiversity, both of which are temporally distant, abstract and general moral patients, but indirectly, by focusing on the concrete and particular lives of extant and near future moral patients. By applying techniques that have been developed to overcome the motivation problem as it pertains to distant future human generations, conservationists have additional resources to draw upon in their efforts to motivate American citizens to preserve biodiversity. This dissertation’s contribution to the fields of environmental philosophy and conservation biology is both theoretical and practical. It is theoretically significant to elucidate the nature of moral failure ...

Ultraviolet Radiation Tolerance in High Elevation Copepods from the Rocky Mountains of Colorado, USA

Description: Copepods in high elevation lakes and ponds in Colorado are exposed to significant levels of ultraviolet radiation (UV), necessitating development of UV avoidance behavior and photoprotective physiological adaptations. The copepods are brightly pigmented due to accumulation of astaxanthin, a carotenoid which has photoprotective and antioxidant properties. Astaxanthin interacts with a crustacyanin-like protein, shifting its absorbance from 473 nm (hydrophobic free form, appears red) to 632 nm (protein-bound complex, appears blue). In six sites in Colorado, habitat-specific coloration patterns related to carotenoprotein complex have been observed. The objective of this study was to determine whether pigment accumulation or carotenoprotein expression has a greater effect on resistance to UV exposure. For each site, copepod tolerance to UV was assessed by survivorship during UV exposure trials. Average UV exposure was determined for each habitat. Astaxanthin profiles were generated for copepods in each site. Ability to withstand UV exposure during exposure trials was significantly different between color morphs (p < 0.0001). Red copepods were found to tolerate 2-fold greater levels of UVB than blue or mixed copepods. Additionally, red copepods have much higher levels of total astaxanthin than blue or mixed copepods (p < 0.0001) and receive a higher daily UV dose (p < 0.0003). Diaptomid carotenoprotein sequence is not homologous with that of other crustaceans in which crustacyanin has been characterized which prevented quantification of carotenoprotein transcript expression. Overall, diaptomid color morph may be an important indicator of UV conditions in high elevation lentic ecosystems.

Development of Indium Oxide Nanowires as Efficient Gas Sensors

Description: Crystalline indium oxide nanowires were synthesized following optimization of growth parameters. Oxygen vacancies were found to impact the optical and electronic properties of the as-grown nanowires. Photoluminescence measurements showed a strong U.V emission peak at 3.18 eV and defect peaks in the visible region at 2.85 eV, 2.66 eV and 2.5 eV. The defect peaks are attributed to neutral and charged states of oxygen vacancies. Post-growth annealing in oxygen environment and passivation with sulphur are shown to be effective in reducing the intensity of the defect induced emission. The as-grown nanowires connected in an FET type of configuration shows n-type conductivity. A single indium oxide nanowire with ohmic contacts was found to be sensitive to gas molecules adsorbed on its surface.

High Efficiency High Power Blue Laser by Resonant Doubling in PPKTP

Description: I developed a high power blue laser for use in scientific and technical applications (eg. precision spectroscopy, semiconductor inspection, flow cytometry, etc). It is linearly polarized, single longitudinal and single transverse mode, and a convenient fiber coupled continuous wave (cw) laser source. My technique employs external cavity frequency doubling and provides better power and beam quality than commercially available blue diode lasers. I use a fiber Bragg grating (FBG) stabilized infrared (IR) semiconductor laser source with a polarization maintaining (PM) fiber coupled output. Using a custom made optical and mechanical design this output is coupled with a mode matching efficiency of 96% into the doubling cavity. With this carefully designed and optimized cavity, measurements were carried out at various fundamental input powers. A net efficie ncy of 81 % with an output power of 680 mW at 486 nm was obtained using 840 mW of IR input. Also I report an 87.5 % net efficiency in coupling of blue light from servo locked cavity into a single mode PM fiber. Thus I have demonstrated a total fiber to fiber efficiency of 71% can be achieved in our approach using periodically poled potassium titanyl phosphate (PPKTP). To obtain these results, all losses in the system were carefully studied and minimized.

Criticism of Beethoven's Pastoral Symphony in London and Boston, 1819-1874: A Forum for Public Discussion of Musical Topics

Description: Critics who discuss Beethoven’s Pastoral Symphony often write about aspects that run counter to their conception of what a symphony should be, such as this symphony’s static nature and its programmatic elements. In nineteenth-century Boston and London, criticism of the Pastoral Symphony reflects the opinions of a wide range of listeners, as critics variably adopted the views of the intellectual elite and general audience members. As a group, these critics acted as intermediaries between various realms of opinion regarding this piece. Their writing serves as a lens through which we can observe audiences’ acceptance of ideas common in contemporaneous musical thought, including the integrity of the artwork, the glorification of genius, and ideas about meaning in music.

The Martial Arts of Medieval Europe

Description: During the late Middle Ages and into the Renaissance, fighting books—Fechtbücher—were produced in northern Italy, among the German states, in Burgundy, and on the Iberian peninsula. Long dismissed by fencing historians as “rough and untutored,” and largely unknown to military historians, these enigmatic treatises offer important insights into the cultural realities for all three orders in medieval society: those who fought, those who prayed, and those who labored. The intent of this dissertation is to demonstrate, contrary to the view of fencing historians, that the medieval works were systematic and logical approaches to personal defense rooted in optimizing available technology and regulating the appropriate use of the skills and technology through the lens of chivalric conduct. I argue further that these approaches were principle-based, that they built on Aristotelian conceptions of arte, and that by both contemporary and modern usage, they were martial arts. Finally, I argue that the existence of these martial arts lends important insights into the world-view across the spectrum of Medieval and early Renaissance society, but particularly with the tactical understanding held by professional combatants, the knights and men-at-arms. Three treatises are analyzed in detail. These include the anonymous RA I.33 Latin manuscript in the Royal Armouries at Leeds; the early German treatise attributed to Hanko Döbringer that glosses the great Johannes Liechtenauer; and the collection of surviving treatises by the Friulian master, Fiore dei Liberi. Each is compared in order to highlight common elements of usage that form the principles of the combat arts.

Electronic Sound Analysis with Hardware System and Remote Internet Display

Description: Currently, standards from government agencies such as the National Institute for Occupation Safety and Health exist to aid in safeguarding individuals’ capacity for hearing, but only in factory settings in which large machines often produce loud levels of sound. Neglecting the fact that these preventative measures are only in place in the most limited of settings, no system currently exists to observe and report sound exposure levels in a manner timely or easily recognizable enough to adequately serve its purpose of hearing conservation. Musicians may also incur significant levels of risk for hearing loss in their day-to-day rehearsals and concerts, from high school marching bands to university wind bands. As a result, music school accrediting organizations such as the National Association of Schools of Music and even the European Union have begun taking steps meant to determine the risks associated with music. To meet these goals and improve upon current technologies, a system has been developed that electronically records sound levels utilizing modern hardware, increases the speed of reporting by transmitting data over computer networks and the Internet, and displays measures calculated from these data in a web browser for a highly viewable, user-friendly interface.

Benthic Macroinvertebrates of Temperate, Sub-Antarctic Streams: The Effects of Altitudinal Zoning and Temperature on the Phenology of Aquatic Insects Associated to the Robalo River, Navarino Island (55°S), Chile

Description: The Cape Horn Biosphere Reserve, within the remote Sub-Antarctic ecoregion is a reservoir of expressions of biological and cultural diversity. Although it is considered one of 24 wilderness areas remaining in the world, it is not free from local and global threats, such as invasive species, and climate change. Field biologists and philosophers associated to the Sub-Antarctic Biocultural Conservation Program and the Omora Ethnobotanical Park, have worked to describe the region’s biocultural diversity, linking ecological and philosophical research into education, ecotourism, and conservation, through a methodology called field environmental philosophy (FEP), which integrates ecological sciences and environmental ethics through a 4-step cycle consisting of: 1) interdisciplinary research; 2) composition of metaphors; 3) design of field activities with an ecological and ethical orientation; and 4) implementation of in situ conservation areas. In this context, the purposes of this dissertation were to: 1) provide a comprehensive review of publications regarding the conservation status of aquatic and terrestrial insects at a global scale and with an emphasis in southern South America; 2) study the distribution of benthic macroinvertebrates through the sharp altitudinal gradient of the Róbalo River watershed; 3) describe the life histories of Gigantodax sp (Simuliidae: Diptera) and Meridialaris chiloeense (Leptophlebiidae: Ephemeroptera) in the Róbalo River and to assess the potential effects of climate change on their phenology; and 4) to apply FEP methodology in order to better understand and communicate the intrinsic and instrumental values of freshwater invertebrates in the Cape Horn Biosphere Reserve.

Podcasting in an Eighth-Grade American History Class

Description: The purpose of this study was to see how students used podcasts in an eighth-grade American history unit and the value they placed on them as an educational tool. The 6-week study was conducted in a suburban middle school in a district that is part of a large metropolitan area in Texas. Participants included 29 students and 2 eighth-grade teachers. The research questions were the following: (1) How do students use podcasts in an eighth-grade American history class? (2) How do students perceive the impact of the podcasts on their overall learning of the subject material? and (3) Do the podcasts motivate the students to study? Quantitative data were collected through a Likert-scaled student survey and logs kept by students. Qualitative data were collected through an open-ended portion of the student survey, student focus group discussion, and a faculty interview. The treatment tools were audio podcasts in the form of vocabulary-quiz reviews, historical vignettes, lectures, and a unit test review—all on the topic of the American Revolution. The data indicated that the students primarily used their computers at home to listen to the podcasts as they prepared for quizzes and/or the unit test. The students believed that the podcasts had a positive impact upon their grade, were a positive educational tool, and helped them to better understand the material at hand. The students also wanted to see an expansion of podcast usage in other subjects. The students claimed that it motivated them to study and the participating teachers agreed that it motivated the students to study in a non-traditional manner. Data illustrated a need for further research regarding podcasting’s impact on grades and performance at the K-12 level, student podcast construction, podcast delivery modes, and podcast use with special education and ELL students.

A General Diffusion of Knowledge: Republican Efforts to Build a Public School System in Reconstruction Texas

Description: From the early days as a Spanish colony Texas attracted settlers with the promise of cheap fertile land. During the period of Mexican control the population of Texas increased and a desire for public education manifested among the people. Through the end of the Civil War government in Texas never provided an adequate means for educating the children of the region. Even when funds became available with the Compromise of 1850 the state only established a school fund to help offset the costs of education, but did not provide a public school system. The first truly successful attempt at mass education in Texas came after the Civil War with the work of the Freedmen’s Bureau. The bureau helped the former slaves adjust to the emerging post war society through a variety of means such as education. In spite of its short existence the bureau managed to educate thousands of African Americans. By 1870 the former slaves wanted more education for their children, and Texans of all races began to see the need for a public school system. This study focuses on Republican efforts during Reconstruction to establish a public school system in Texas to meet the educational needs of its children. An analysis of data from county, state, and federal records forms the basis of this study. The data suggests that Republican efforts were hampered by the opposition of Texans to high taxes, compulsory education, racism, and animosity toward that party for emancipation and Civil War.

Fashion-brand Experiences in Multi-channel Retailing: Impacts of Experience Dimensions and Experience Types on Brand Resonance

Description: The brand behind the garment is what gives the product popularity, relevance to the consumer, and overall profitability. As time passes, markets are becoming flooded with more brands that inherently provide the commodities. As a result, fashion marketers must put more time and investment into stipulating ways for which their brand can reach a select target consumer and enhance repeat purchase intentions with their competitive differentiations. As their efforts engage, an experiential perspective emerges in the fashion industry. By comparing fashion brands and their different distribution channels, the objectives of this study are to identify consumers’ perceptions of fashion brand experience dimensions and experience types, and to investigate the effect of brand experience dimensions and types on brand resonance. Upon extending Schmitt and Brakus, Schmitt, and Zarantonello’s experience dimensions and types, in conjunction with Keller’s brand resonance model, 12 out of 20 hypotheses confirm the significant impact of consumers experiences on brand resonance by analyzing the data (n = 374) from a university in the United States. Sensory and affective experiences are primary factors for establishing fashion brand association, while cognitive and relational driven experiences lead to establishing fashion brand loyalty. Sensory, affective, and relational experiences affect both product and store type experiences, while only product experience affects brand resonance. With the depiction of different brand effects, this study concludes that while Forever 21 may focus on relational experiences with the consumer, Gap utilizes positive cognitive experiences to develop a link to brand loyalty and fashion product reliability.
