Breaking the Doubler Barrier: Using Sy Brandon’sDivertissement to Demonstrate a Practical Approach to Performing Multiple WoodwindWorks

Breaking the Doubler Barrier: Using Sy Brandon’sDivertissement to Demonstrate a Practical Approach to Performing Multiple WoodwindWorks

Date: December 2014
Creator: Levels, Brian Eugene
Description: Multiple woodwind training is ideal for securing certain types of employment; however, with so many different instruments, performance standards on each are difficult to maintain. Furthermore, for many multiple woodwind players, proficiency on all woodwinds ceases to be a top priority after graduation, even though they continue to market themselves as highly proficient on all of these instruments. The problem for most begins with what it means to be proficient on each instrument. The technical demands of multiple woodwind performance vary widely, but often a performance calls for complete proficiency on a variety of instruments. Multiple woodwind players who lack in professional level proficiency damage the credibility of the field and jeopardize employment opportunities for others. This study aims to address the common problems involving proficiency and to help multiple woodwind players, band directors, and doublers become familiar with and overcome these common pitfalls. Sy Brandon’s Divertissement provides an outstanding platform to address problems and provide solutions for multiple wind players, band directors, and doublers. This dissertation serves as a multiple woodwind specialist’s resource for maximum efficiency in learning and playing repertoire that involves multiple woodwinds, such as musicals, and other multiple woodwind genres.

The Power of Perception: Women and Politics at the Early Georgian Court

The Power of Perception: Women and Politics at the Early Georgian Court

Date: August 2014
Creator: Stewart, Hailey A.
Description: The early Georgian period illustrates how the familial dynamic at court affected women’s opportunity to exert political influence. The court represented an important venue that allowed women to declare a political affiliation and to participate in political issues that suited their interests. Appearances often at variance with reality allowed women to manipulate and test their political abilities in order to have the capability to exercise any possible power. Moreover, some women developed political alliances and relationships that supported their own interests. The family structure of the royal household affected how much influence women had. The perception of holding power permitted certain women to behave politically. This thesis will demonstrate that the distinction between appearances and reality becomes vital in assessing women at the early Georgian court by examining some women’s experiences at court during the reigns of the first two Georges. In some cases, the perceived power of a courtier had a real basis, and in other instances, it gave them an opportunity to assess the extent of their political power. Women’s political participation has been underestimated during the early Georgian period, while well-documented post-1760.

Glass Forming Ability, Magnetic Properties, and Mechanical Behavior of Iron-Based and Cobalt-Based Metallic Glasses

Glass Forming Ability, Magnetic Properties, and Mechanical Behavior of Iron-Based and Cobalt-Based Metallic Glasses

Date: December 2014
Creator: Veligatla, Medha
Description: Lack of crystalline order and microstructural features such as grain/grain-boundary in metallic glasses results in a suite of remarkable attributes including very high strength, close to theoretical elasticity, high corrosion and wear resistance, and soft magnetic properties. In particular, low coercivity and high permeability of iron and cobalt based metallic glass compositions could potentially lead to extensive commercial use as magnetic heads, transformer cores, circuits and magnetic shields. In the current study, few metallic glass compositions were synthesized by systematically varying the iron and cobalt content. Thermal analysis was done and included the measurement of glass transition temperature, crystallization temperature, and the enthalpies of relaxation and crystallization. Magnetic properties of the alloys were determined including saturation magnetization, coercivity, and Curie temperature. The coercivity was found to decrease and the saturation magnetization was found to increase with the increase in iron content. The trend in thermal stability, thermodynamic properties, and magnetic properties was explained by atomic interactions between the ferromagnetic metals and the metalloids atoms in the amorphous alloys. Mechanical behavior of iron based metallic glasses was evaluated in bulk form as well as in the form of coatings. Iron based amorphous powder was subjected to high power mechanical milling and ...

The Role of the Actin Cytoskeleton in Asymmetric Cell Division in Maize

The Role of the Actin Cytoskeleton in Asymmetric Cell Division in Maize

Date: August 2014
Creator: Alhassan, Hassan Hamdan
Description: Stomata are specialized plant structures required for gaseous exchange with the outer environment. During stomata formation, the cytoskeleton plays an important role in controlling the division of the individual cells leading to the generation of the stomata complex. Two mutants that affect microfilament and microtubule organization in subsidiary mother cells include brk1 and dcd1. While only 20% of the subsidiary cells in the brk1 and dcd1 single mutants are abnormally shaped, it was reported that there is a synergistic effect between the brk1 and dcd1 mutations in the brk1; dcd1 double mutant since 100% of the subsidiary cells are abnormal. The focus of this research is to try to understand this synergistic effect by investigating the actin cytoskeleton and nuclear position in the single and double mutants. The reported results include the observation that the size of actin patch was largest in the wild-type subsidiary mother cells (SMCs) and smallest in dcd1 and brk1; dcd1 SMCs and that brk1 and brk1; dcd1 double mutants had fewer actin patches than wild-type and dcd1 SMCs. Additionally, we observed that some SMCs that did not have actin patches still underwent nuclear migration suggesting that nuclear migration may not be solely dependent on actin ...

Measuring Teaching Effectiveness Using Value-added and Observation Rubric Scores

Measuring Teaching Effectiveness Using Value-added and Observation Rubric Scores

Date: December 2014
Creator: McKenzie, Andrew
Description: This mixed-methods study examined the extent to which teacher performance and student performance measures correlated, and to understand which specific practices of mathematics teachers in Grades 3-5 related to student performance. Research was conducted at five elementary schools in a large, urban north Texas school district. Data sources included component scores and recorded evidence from observation rubrics, interviews with campus administrators, and value-added modeling (VAM) student growth scores. Findings indicated a modest relationship between teacher performance levels and student performance levels. Lack of access to individual teacher VAM data, per district policy, might have impacted the strength of the relationship. Interviews with administrators and an examination of the evidence cited in the observation rubrics identified specific practices associated with highly rated mathematics teaching. Differences in administrators’ experience levels with both mathematics instruction and the observation instrument might have influenced rubric scores and the level of specificity shown in evidence statements.

Studies of Charged Particle Dynamics for Antihydrogen Synthesis

Studies of Charged Particle Dynamics for Antihydrogen Synthesis

Date: December 2014
Creator: Correa, Jose Ricardo
Description: Synthesis and capture of antihydrogen in controlled laboratory conditions will enable precise studies of neutral antimatter. The work presented deals with some of the physics pertinent to manipulating charged antiparticles in order to create neutral antimatter, and may be applicable to other scenarios of plasma confinement and charged particle interaction. The topics covered include the electrostatic confinement of a reflecting ion beam and the transverse confinement of an ion beam in a purely electrostatic configuration; the charge sign effect on the Coulomb logarithm for a two component (e.g., antihydrogen) plasma in a Penning trap as well as the collisional scattering for binary Coulomb interactions that are cut off at a distance different than the Debye length; and the formation of magnetobound positronium and protonium.

Immunity for New Mexico Public School Districts and the 1978 Tort Claims Act

Immunity for New Mexico Public School Districts and the 1978 Tort Claims Act

Date: August 2014
Creator: Herauf, Todd J.
Description: In a 3-year timeframe, nearly 800 student negligence suits were filed, and most involved some claim of personal injury. Despite heightened public attention of negligence lawsuits against school districts and their employees, an empirical study of court decisions revealed that the volume of litigation against school districts remained steady from 1990 to 2005, the majority of cases were ruled in favor of the school district employees, and government and official immunity were most often the basis for these rulings. Researchers have concluded that immunity laws are strong in the United States, although they vary by state in their application. However, a primary recommendation was that, because of the misconception of a lack of immunity for public school employees, a comprehensive study on governmental and official immunity is needed. This dissertation employed legal research, analysis, and methodology to engage in a comprehensive investigation of teacher immunity in the four southern states of Texas, Oklahoma, Mississippi, and New Mexico. Of central concern to this dissertation was the Tort Claims Act of 1978 from the State of New Mexico. The Tort Claims Act is the vehicle by which immunity is granted to public school employees. Court findings over the last 35 years point ...

Evidence for Multiple Functions of a Medicago Truncatula Transporter

Evidence for Multiple Functions of a Medicago Truncatula Transporter

Access: Use of this item is restricted to the UNT Community.
Date: December 2014
Creator: Huang, Ying-Sheng
Description: Legumes play an important role in agriculture as major food sources for humans and as feed for animals. Bioavailable nitrogen is a limiting nutrient for crop growth. Legumes are important because they can form a symbiotic relationship with soil bacteria called rhizobia that results in nitrogen-fixing root nodules. In this symbiosis, rhizobia provide nitrogen to the legumes and the legumes provide carbon sources to the rhizobia. The Medicago truncatula NPF1.7/NIP/LATD gene is essential for root nodule development and also for proper development of root architecture. Work in our lab on the MtNPF1.7/MtNIP/LATD gene has established that it encodes a nitrate transporter and strongly suggests it has another function. Mtnip-1/latd mutants have pleiotropic defects, which are only partially explained by defects in nitrate transport. MtNPF1.7/NIP/LATD is a member of the large and diverse NPF/NRT1(PTR) transporter family. NPF/NRT1(PTR) members have been shown to transport other compounds in addition to nitrate: nitrite, amino acids, di- and tri-peptides, dicarboxylates, auxin, abscisic acid and glucosinolates. In Arabidopsis thaliana, the AtNPF6.3/NRT1.1( CHL1) transporter was shown to transport auxin as well as nitrate. Atchl1 mutants have defects in root architecture, which may be explained by defects in auxin transport and/or nitrate sensing. Considering the pleiotropic phenotypes observed ...

Prokofiev Beckons the Double Bass Into the Modern Age: a Pedagogical Study of the Op 39 Quintet

Prokofiev Beckons the Double Bass Into the Modern Age: a Pedagogical Study of the Op 39 Quintet

Date: August 2014
Creator: Jones, Kathryn E.
Description: Until Serge Prokofiev’s 1924 ballet score Trapèze, the double bass occupied a background or at best a doubling role in almost all composers’ use of the instrument. Technical challenge was limited in these pieces, because composers did not see the instrument’s potential in a chamber music environment. As luthiers developed the instrument, the technical ability of players grew, and composers began writing more challenging music for the instrument. As one of the first major composers to see the double bass in a new light, Prokofiev wrote challenging music for the instrument. This paper illuminates the alluring pedagogical aspects of Prokofiev's Quintet in G Minor, Op. 39 and provides recommendations for accomplishing some difficult passages with ease.

An Assessment of a Hospice and Palliative Care Partnership Program

An Assessment of a Hospice and Palliative Care Partnership Program

Date: December 2014
Creator: Munene, Grace N
Description: This project attempts to describe how a hospice and palliative care partnership program works. Through the assessment of one such program, the researcher sought to find out the essential components of the partnership including how the two partner organizations interact and work together. Data was collected using various methods: document review of organization documents such as newsletters, annual or quarterly reports, brochures and other available literature e.g. materials on organizations’ website and on social media; in-depth interviews with stakeholders of both organizations that included staff and board members; observation of staff working; and participant observation during organization events. The findings of the research shows that in order for organizations to have an effective partnership program in place, both partners need to have strong leadership in place, possess a willingness to learn from each other, maintain regular communication, and visit each other regularly. With this in place, several outcomes of the program are likely such as: increasing advocacy for hospice and palliative care, increasing visibility of the organizations both nationally and internationally, and provides an opportunity for organizations to network with other organizations in their locality in order to achieve partnership objectives. The study further reveals that global collaborations in the ...
