King Fisher: The Short Life and Elusive Career of a Texas Desperado

Access: Use of this item is restricted to the UNT Community
America’s Wild West created an untold number of notorious characters, and in southwestern Texas, John King Fisher (1855– 1884) was foremost among them. To friends and foes alike, he insisted he be called “King.” He found a home in the tough sun-beaten Nueces Strip, a lawless land between the Nueces River and the Rio Grande. There he gathered a gang of rustlers around him at his ranch on Pendencia Creek. For a decade King and his gang raided both sides of the Rio Grande, shooting down any who opposed them. Newspapers claimed King killed potential witnesses—he was never convicted of cattle or horse stealing, or murder. King’s reign ended when he was arrested by Texas Ranger Captain Leander McNelly. In no uncertain terms he advised Fisher to change his ways, so King became deputy sheriff of Uvalde County. But his hard-won respectability would not last. On a spring night in 1884, King made the mistake of accompanying the truly notorious gambler and gunfighter Ben Thompson on a tour of San Antonio, where several years prior Thompson shot down Jack Harris at the latter’s saloon and theater, the Vaudeville. Recklessly, King Fisher accompanied Thompson back to the theater, where assassins were …

UV Magnetic Plasmons in Cobalt Nanoparticles

Access: Use of this item is restricted to the UNT Community
The main goals of this research were to fabricate magnetic cobalt nanoparticles and study their structural, crystal structure, optical, and magnetic properties. Cobalt nanoparticles with average particle size 8.7 nm were fabricated by the method of high temperature reduction of cobalt salt utilizing trioctylphosphine as a surfactant, oleic acid as a stabilizer, and lithium triethylborohydride as a reducing reagent. Energy-dispersive X-ray spectroscopy (EDX) analysis confirmed the formation of cobalt nanoparticles. High resolution transmission electron microscopy images show that Co NPs form both HCP and FCC crystal structure. The blocking temperature of 7.6 nm Co NPs is 189 K. Above the blocking temperature, Co NPs are single domain and hence showed superparamagnetic behavior. Below the blocking temperature, Co NPs are ferromagnetic. Cobalt nanoparticles with a single-domain crystal structure support a sharp plasmon resonance at 280 nm. Iron nanoparticles with average particle size 4.8 nm were fabricated using chemical reduction method show plasmon resonance at 266 nm. Iron nanoparticles are ferromagnetic at 6 K and superparamagnetic at 300 K.

Beneath Missouri Skies: Pat Metheny in Kansas City 1964-1972

Access: Use of this item is restricted to the UNT Community
The New Yorker recently referred to Pat Metheny as “possibly the most influential jazz guitarist of the past five decades.” A native of Lee’s Summit, Missouri, just southeast of Kansas City, Metheny started playing in pizza parlors at age fourteen. By the time he graduated from high school he was the first-call guitarist for Kansas City jazz clubs, private clubs, and jazz festivals. Now 66, he attributes his early success to the local musical environment he was brought up in and the players and teachers who nurtured his talent and welcomed him into the jazz community. Metheny’s twenty Grammys in ten categories speak to his versatility and popularity. Despite five decades of interviews, none have conveyed in detail his stories about his teenage years. Beneath Missouri Skies also reveals important details about jazz in Kansas City during the sixties and early seventies, often overlooked in histories of Kansas City jazz. Yet this time of cultural change was characterized by an outstanding level of musicianship.

Recovering an Irish Voice from the American Frontier: The Prose Writings of Eoin Ua Cathail

Access: Use of this item is restricted to the UNT Community
Recovering an Irish Voice from the American Frontier is a bilingual compilation of stories by Eoin Ua Cathail, an Irish emigrant, based loosely on his experiences in the West and Midwest. The author draws on the popular American Dime Novel genre throughout to offer unique reflections on nineteenth-century American life. As a member of a government mule train accompanying the U.S. military during the Plains Indian Wars, Ua Cathail depicts fierce encounters with Native American tribes, while also subtly commenting on the hypocrisy of many famine-era Irish immigrants who failed to recognize the parallels between their own plight and that of dispossessed Native peoples. These views are further challenged by his stories set in the upper Midwest. His writings are marked by the eccentricities and bloated claims characteristic of much American Western literature of the time, while also offering valuable transnational insights into Irish myth, history, and the Gaelic Revival movement. This bilingual volume, with facing Irish-English pages, marks the first publication of Ua Cathail’s work in both the original Irish and in translation. It also includes a foreword from historian Richard White, a comprehensive introduction by Mahoney, and a host of previously unpublished historical images.

Examining Employee Satisfaction, Customer Service and Customer Satisfaction in a Retail Banking Organization

Access: Use of this item is restricted to the UNT Community
In the increasingly competitive world of retail banking, organizations are focusing their attention on customer service as a means of increasing customer loyalty and retention. With this goal of increasing customer retention, the link between the attitudes of the service provider (employee satisfaction), the customer interaction behaviors that those attitudes lead to (customer service quality), and the attitudes that those behaviors generate in the customer (customer satisfaction) has become an increasingly important area of investigation. The goal of this research is to analyze the relationships that exist between these three variables: employee satisfaction, customer service quality, and customer satisfaction in a mid-sized retail bank. Data from three separate surveys collected during the same time period in 137 branches of a regional bank are analyzed using multiple regression analysis to determine whether relationships and interactions exist at a banking center level. While results of the analyses did not show a significant relationship between the variables, issues relevant to this determination are discussed and conclusions drawn regarding the nature of these constructs.

Copper Wire-Bonding Reliability: Mechanism and Prevention of Galvanic Aluminum Bond Pad Corrosion in Acidic Chloride Environments

Access: Use of this item is restricted to the UNT Community
With the reliability requirements of automobile microelectronics pushing towards near 0 ppb levels of failure control, halide induced corrosion issues in wire bonded devices have to be tightly controlled to achieve such a high reliability goal. With real-time corrosion monitoring, for the first time we demonstrated that the explosive H2 evolution coupled with the oxygen reduction reaction, occurring at the critical Al/Cu interfaces, is the key driving force for the observed aggressive corrosion. Several types of passivation coating on Cu wire surfaces to effectively block the cathodic H2 evolution were explored with an aim to disrupt this explosive corrosion cycle. The properties of the protective coating were evaluated using various analytical techniques. The surface coating exhibited high thermal stability up to 260 °C (evaluated using TGA analysis). A uniform, highly hydrophobic coating (surface contact angle of >130° with water), was achieved by carefully controlling CVD parameters such as time of deposition, surface control of Cu metal, amount of inhibitor compound loading, temperature of coating process etc. FTIR spectroscopy combined with corrosion screening was used to optimize the CVD passivated coating with strong chemisorption. SEM and EDX, XPS were carried out on various coated surfaces to understand the composition and selectivity …

Cold-Formed Steel Member Connections Using BAC Screw Fasteners

Access: Use of this item is restricted to the UNT Community
In this project, the main research objective is intend to seek criteria for evaluating the capacity of BAC screw fasteners with mixed configuration of waterproof seal washer, sealer tape and different pre-drill holes to determine shear and tension strength values for the screws used in cold-formed steel connections. The thesis presents the design methods and test program conducted to investigate the behavior and strength of the screw connections in shear and tension test. Test results were compared with AISI design provisions to determine if new design equations will be developed for those screws used in BAC cooling tower applications. LRFD resistance factors and ASD safety factors were investigated to the proposed design equations.
