A Countertenor Aria Collection Continuum for Studio Training and Performance

Description: An assessment of the standard voice instructor or performer collection of printed music would likely reveal numerous operatic repertoire volumes in anthology format appropriated to the primary four voice categories. However, thorough investigation divulges little in comparable printed material accessible to the countertenor. This scarcity of systemized collections is especially evident in the territory of comprehensive countertenor operatic repertoire. This project fills that present void by cr… more

A National Idiom Universally Understood: Brazilian Tradition and Personal Evolution in Osvaldo Lacerda's "Variações e Fuga para quinteto de sopros"

Description: The career of Osvaldo Lacerda (1927-2011) spanned a critical time in the development of Brazilian nationalist music. Though he was an outspoken nationalist composer, he was also influenced by European trends and training. Even within his nationalist compositions, evidence of a shift in style that mirrors the European movements of Modernism and Postmodernism is found in his works. Among his thirty-six chamber works, three are wind quintets, written between 1962 and 1997. Although all three works… more

Assessing Perception and Attitude of Pianists toward Ergonomically Scaled Piano Keyboards (ESPK): Raising Awareness about ESPK and Evaluating Changes of Attitude through an Educational Survey

Description: As epidemiologic research demonstrates health concerns for hand problems among pianists, scientists are measuring historic piano keyboards and realizing that much of the piano literature was composed for and played on pianos with smaller keys compared to what is used on the modern piano. Having to play this literature on a larger keyboard is especially difficult for small-handed piano students and professionals. Fortunately, smaller keyboards are now available for use with standard pianos - and… more

The Nature of Cognitive Impairment in Multiple Sclerosis

Description: Cognitive impairment is common in multiple sclerosis (MS), with as many as 70% of patients with MS affected. Individuals with MS who experience cognitive deficits are less likely to be employed, and may have more difficulty performing independent activities of daily living. Most commonly, deficits are observed in processing speed, complex attention, and memory. Because lesion location varies widely among individuals, no clear pattern of cognitive dysfunction in MS has emerged. However, a number… more

High-Energy, Long-Lived Charge-Separated States via Molecular Engineering of Triplet State Donor-Acceptor Systems

Description: Molecular engineering of donor-acceptor dyads and multimodular systems to control the yield and lifetime of charge separation is one of the key goals of artificial photosynthesis for harvesting sustainably solar energy. The design of the donor-acceptor systems mimic a part of green plants and bacterial photosynthetic processes.

Genomic Island Discovery through Enrichment of Statistical Modeling with Biological Information

Description: Horizontal gene transfer enables acquisition and dissemination of novel traits including antibiotic resistance and virulence among bacteria. Frequently such traits are gained through the acquisition of clusters of functionally related genes, often referred to as genomic islands (GIs). Quantifying horizontal flow of GIs and assessing their contributions to the emergence and evolution of novel metabolic traits in bacterial organisms are central to understanding the evolution of bacteria in genera… more

Infinitely Many Solutions of Semilinear Equations on Exterior Domains

Description: We prove the existence and nonexistence of solutions for the semilinear problem ∆u + K(r)f(u) = 0 with various boundary conditions on the exterior of the ball in R^N such that lim r→∞u(r) = 0. Here f : R → R is an odd locally lipschitz non-linear function such that there exists a β > 0 with f < 0 on (0, β), f > 0 on (β, ∞), and K(r) \equiv r^−α for some α > 0.

The Effects of the $0.50-Debt Test on Fast Growth Texas School Districts: A Case Study of Three Districts

Description: A three-district case study was conducted to determine the effects of the 50-cent debt test on fast-growth Texas school districts. The 50-cent debt test for Texas schools came into existence as part of Senate Bill 351 in 1991. Prior to the passing of Senate Bill 351, districts in Texas were limited to issuing 10% of their assessed valuation. Of the 75 school districts that currently meet the criteria to be considered a fast-growth district, 15 of the districts had an Interest and Sinking tax… more

Keep Calm and Play On: The Effects of Grit, Mindfulness, and Goal Orientation on Sport Anxiety and Performance

Description: Achievement motivation theory suggests there are two primary approaches to achievement tasks: to appear competent or to develop a skill. These two different approaches to performance yield different affective and behavioral responses. Athletes holding a performance goal orientation tend to respond to challenges with behaviors exemplifying learned helplessness and increased anxiety. Athletes holding a mastery goal orientation tend to respond to challenges with greater effort and experience less … more

The Effectiveness of the PAI in Identifying Minimized Substance Use and Predicting Poor Treatment Outcomes in an Offender Population

Description: The accurate evaluation of substance use is a critical component of forensic assessment due to the well-established link between drug use sentencing issues and risk of recidivism. Due to limited resources and chronic time constraints, practitioners typically rely only on self-report measures to assess substance use (SU) patterns. As these measures directly inquire about SU patterns, they remain vulnerable to response distortion. This can lead to ineffective treatment recommendations made to … more

Use of Bio-Product/Phase Change Material Composite in the Building Envelope for Building Thermal Control and Energy Savings

Description: This research investigates the bio-products/phase change material (PCM) composites for the building envelope application. Bio-products, such as wood and herb, are porous medium, which can be applied in the building envelope for thermal insulation purpose. PCM is infiltrated into the bio-product (porous medium) to form a composite material. The PCM can absorb/release large amount of latent heat of fusion from/to the building environment during the melting/solidification process. Hence, the PCM-b… more
