Description
A new arrangement of the Concerto for Two Horns in E-flat Major, Hob. VIId/6, attributed by some to Franz Joseph Haydn, is presented here. The arrangement reduces the orchestral portion to ten wind instruments, specifically a double wind quintet, to facilitate performance of the work. A full score and a complete set of parts are included. In support of this new arrangement, a discussion of the early treatment of horns in pairs and the subsequent development of the double horn concerto in the eighteenth century provides historical context for the Concerto for Two Horns in E-flat major. A summary of the controversy concerning the identity of the composer of this concerto is followed by a description of the content and structure of each of its three movements. Some comments on the procedures of the arrangement complete the background information.

Description
The elaborate signals of animals are often costly to produce and maintain, thus communicating reliable information about the quality of an individual to potential mates or competitors. The properties of the sensory systems that receive signals can drive the evolution of these signals and shape their form and function. However, relatively little is known about the ecological and physiological constraints that may influence the development and maintenance of sensory systems. In the house finch (Carpodacus mexicanus) and many other bird species, carotenoid pigments are used to create colorful sexually selected displays, and their expression is limited by health and dietary access to carotenoids. Carotenoids also accumulate in the avian retina, protecting it from photodamage and tuning color vision. Analogous to plumage carotenoid accumulation, I hypothesized that avian vision is subject to environmental and physiological constraints imposed by the acquisition and allocation of carotenoids. To test this hypothesis, I carried out a series of field and captive studies of the house finch to assess natural variation in and correlates of retinal carotenoid accumulation and to experimentally investigate the effects of dietary carotenoid availability, immune activation, and light exposure on retinal carotenoid accumulation. Moreover, through dietary manipulations of retinal carotenoid accumulation, I tested the impacts of carotenoid accumulation on visually mediated foraging and mate choice behaviors. My results indicate that avian retinal carotenoid accumulation is variable and significantly influenced by dietary carotenoid availability and immune system activity. Behavioral studies suggest that retinal carotenoid accumulation influences visual foraging performance and mediates a trade-off between color discrimination and photoreceptor sensitivity under dim-light conditions. Retinal accumulation did not influence female choice for male carotenoid-based coloration, indicating that a direct link between retinal accumulation and sexual selection for coloration is unlikely. However, retinal carotenoid accumulation in males was positively correlated with their plumage coloration. Thus, carotenoid-mediated visual health and performance or may be part of the information encoded in sexually selected coloration.

Description
Molecular dynamics (MD) simulations provide a particularly useful approach to understanding conformational change in biomolecular systems. MD simulations provide an atomistic, physics-based description of the motions accessible to biomolecular systems on the pico- to micro-second timescale, yielding important insight into the free energy of the system, the dynamical stability of contacts and the role of correlated motions in directing the motions of the system. In this thesis, I use molecular dynamics simulations to provide molecular mechanisms that rationalize structural, thermodynamic, and mutation data on the interactions between the lac repressor headpiece and its O1 operator DNA as well as the ERK2 protein kinase. I performed molecular dynamics simulations of the lac repressor headpiece - O1 operator complex at the natural angle as well as at under- and overbent angles to assess the factors that determine the natural DNA bending angle. I find both energetic and entropic factors contribute to recognition of the natural angle. At the natural angle the energy of the system is minimized by optimization of protein-DNA contacts and the entropy of the system is maximized by release of water from the protein-DNA interface and decorrelation of protein motions. To identify the mechanism by which mutations lead to auto-activation of ERK2, I performed a series of molecular dynamics simulations of ERK1/2 in various stages of activation as well as the constitutively active Q103A, I84A, L73P and R65S ERK2 mutants. My simulations indicate the importance of domain closure for auto-activation and activity regulation. My results enable me to predict two loss-of-function mutants of ERK2, G83A and Q64C, that have been confirmed in experiments by collaborators. One of the powerful capabilities of MD simulations in biochemistry is the ability to find low free energy pathways that connect and explain disparate structural data on biomolecular systems. An extention of the targeted molecular dynamics technique using constraints on internal coordinates will be presented and evaluated. The method gives good results for the alanine dipeptide, but breaks down when applied to study conformational changes in GroEL and adenylate kinase.

Description
The purpose of this project is to introduce Bryan Johanson's composition for two guitars, 13 Ways of Looking at 12 Strings, and present an authoritative recording appropriate for publishing. This fifty-minute piece represents a fascinating suite in thirteen movements. The author of this project performed both guitar parts, recorded them separately in a music studio, then mixed them together into one recording. This document focuses on the critical investigation and description of the piece with a brief theoretical analysis, a discussion of performance difficulties, and guitar preparation. The composer approved the use and the scope of this project. Bryan Johanson is one of the leading contemporary composers for the guitar today. 13 Ways of Looking at 12 Strings is a unique guitar dictionary that takes us from Bach to Hendrix and highlights the unique capabilities of the instrument. It utilizes encoded messages, glass slides, metal mutes, explosive "riffs," rhythmic propulsion, improvisation, percussion, fugual writing, and much more. It has a great potential to make the classical guitar attractive to wider audiences, not limited only to guitarists and musicians. The main resources employed in researching this document are existing recordings of Johanson's other compositions and documentation of his personal views and ideas. This written document uses the composer's prolific and eclectic compositional output in order to draw conclusions and trace motifs. This project is a significant and original contribution in expanding the guitar's repertoire, and it uniquely contributes to bringing forth a significant piece of music.

Description
The purpose of this project was to commission, perform, and discuss a new work for an instrument pairing not often utilized, oboe and percussion. The composer, Alyssa Morris, was selected in June 2009. Her work, titled Forecast, was completed in October of 2009 and premiered in February of 2010, as part of a program showcasing music for oboe and percussion. Included in this document is a detailed biography of the composer, a description of the four movements of Forecast, performance notes for each movement, a diagram for stage set-up, the full score, the program from the premiere performance with biographies of all the performers involved, and both a live recording and MIDI sound file. The performance notes discuss issues that arose during preparation for the premiere and should help avoid potential pitfalls. TrevCo Music, publisher of the work, graciously allowed inclusion of the full score. This score is solely for use in this document; please visit the publisher's website for purchasing information. The commission and documentation of this composition are intended to add to the repertoire for oboe in an unusual instrument pairing and to encourage further exploration of such combinations.

Description
The focus of this study was the first Serbian opera, Na Uranku (At Dawn). It was written by Stanislav Binièki (1872-1942) and was first performed in 1903 at the National Theatre in Belgrade. There were two objectives of this project: (1) a live concert performance of the opera, which produced an audio recording that can be found as an appendix; and, (2) an accompanying document containing a history and an analysis of the work. While Binièki's opera is recognized as an extraordinary artistic achievement, and a new genre of musical enrichment for Serbian music, little had been previously written either about the composer or the work. At Dawn is a romantic opera in the verismo tradition with national elements. The significance of this opera is not only in its artistic expression but also in how it helped the music of Serbia evolve. Early opera settings in Serbia in the mid-nineteenth to early twentieth century did not have the same wealth of history upon which to draw as had existed in the rich operatic oeuvre in Western Europe and Russia. Similarly, conditions for performance were not satisfactory, as were no professional orchestras or singers. Furthermore, audiences were not accustomed to this type of art form. The opera served as an educational instrument for the audience, not only training them to a different type of music but also evolving its national consciousness. Binièki's opera was a foundation on which later generations of composers built. The artistic value of this opera is emphasized. The musical language includes an assimilation of various influences from Western Europe and Russia, properly incorporated into the Serbian musical core. Audience reaction is discussed, a positive affirmation that Binièki was moving in the right direction in establishing a path for the further development of the artistic field of Serbian musical culture. A synopsis of the work as well as the requisite performing forces is also included.

Description
In the 1970s James Watson recognized the inability of conventional DNA replication machinery to replicate the extreme termini of chromosomes known as telomeres. This inability is due to the requirement of a building block primer and was termed the end replication problem. Telomerase is nature's answer to the end replication problem. Telomerase is a ribonucleoprotein which extends telomeres through reverse transcriptase activity by reiteratively copying a short intrinsic RNA sequence to generate 3' telomeric extensions. Telomeres protect chromosomes from erosion of coding genes during replication, as well as differentiate native chromosome ends from double stranded breaks. However, controlled erosion of telomeres functions as a naturally occurring molecular clock limiting the replicative capacity of cells. Telomerase is over activated in many cancers, while inactivation leads to multiple lifespan limiting human diseases. In order to further study the interaction between telomerase RNA (TR) and telomerase reverse transcriptase protein (TERT), vertebrate TERT fragments were screened for solubility and purity following bacterial expression. Soluble fragments of medaka TERT including the RNA binding domain (TRBD) were identified. Recombinant medaka TRBD binds specifically to telomerase RNA CR4/CR5 region. Ribonucleotide and amino acid pairs in close proximity within the medaka telomerase RNA-protein complex were identified using photo-activated cross-linking in conjunction with mass spectrometry. The identified cross-linking amino acids were mapped on known crystal structures of TERTs to reveal the RNA interaction interface of TRBD. The identification of this RNA TERT interaction interface furthers the understanding of the telomerase complex at a molecular level and could be used for the targeted interruption of the telomerase complex as a potential cancer treatment.

Description
Dr. Jerold D. Ottley's twenty-five years leading the Mormon Tabernacle Choir resulted in many distinguished awards and recognitions for the ensemble. Included among these are two Platinum and three Gold records from the Recording Industry Association of America, an Emmy from the Academy of Television Arts and Sciences, and two Freedom Foundation Awards for service to the country. He conducted the Choir at two presidential inaugurations, Ronald Reagan's in 1981 and George H. W. Bush's in 1989, as well as performances at the 1984 Los Angeles Olympics Gala. He presided over eleven international tours to twenty-six countries and crisscrossed the United States for engagements in nearly every region of the country. Despite the awards, commendations, and increased recognition of the Choir, Ottley's greatest contributions were largely internal to the organization. Jerold Ottley is a skilled music educator, administrator, and emissary. Application of these proficiencies while at the helm of the Choir, led to what are, arguably, his three largest contributions: 1) as educator, he instituted in-service training for choir members, raising the level of their individual musicianship, thereby improving the technical level of the entire Choir; 2) as administrator, Ottley created policies and procedures that resulted in a more disciplined, refined ensemble; and 3) as emissary, he raised the ensemble's reputation among the general public and with music professionals. For the general public, he significantly broadened the Choir's repertoire and traveled frequently thereby reaching a wider audience. He secured greater respect among music professionals by inviting many of them to work directly with the Choir. The results were unparalleled. Ottley's twenty-five year tenure with the Choir is reflected in broader audiences, increased professional acceptance, added organizational discipline, and unprecedented musical proficiency. It is a notable legacy for a man who reportedly never felt comfortable as director of the Mormon Tabernacle Choir.

Description
A systematic approach to composition has been used by a variety of composers to control an assortment of musical elements in their pieces. This paper begins with a brief survey of some of the important systematic approaches that composers have employed in their compositions, devoting particular attention to Pierre Boulez's Structures Ia . The purpose of this survey is to examine several systematic approaches to composition by prominent composers and their philosophy in adopting this type of approach. The next section of the paper introduces my own systematic approach to composition: the Take-Away System. The third provides several musical applications of the system, citing my work, Octulus for two pianos, as an example. The appendix details theorems and observations within the system for further study.

Description
The purpose of this study was to examine the effects of an after-school music program on music underachievers' musical achievement, social development and self-esteem. A true-experimental pretest-posttest design was used and included 14 hours of treatment time. The subjects (N = 66), fifth-grade students were randomly selected from the lowest quartile of scores on Colwell's Music Achievement Test (MAT), which was administered to all fifth-grade students (N = 494) in three Korean elementary schools. The treatment group (n =33) experienced a movement-based after-school music program (MAMP); the control group (n = 33) did not receive the after-school music program. Measurements included sections of Colwell's Music Achievement Test (MAT), Kim's Social Development Scale (SDS), and Hare's Self-Esteem Scale (HSS). The researcher and music teachers of each school administered all measurements. Fourteen treatment lessons occurred over fourteen weeks. One-way analyses of covariance tests were used to test for post-test differences between groups. A significant difference was found in music achievement total scores of the MAT with the treatment group scoring higher scores than the control group. There were no significant differences for interval and meter discrimination tests of MAT. There were no significant differences between treatment and control groups in the post-test scores of the Social Development Scale (SDS) and the Self-Esteem Scale (HSS). However, for both tests, mean scores increased for the treatment group and decreased for the control group. Results from this study suggest that a movement-based after-school music program promotes music underachievers' musical growth and may also support music underachievers' social development and self-esteem.
