The First Movements of Sergei Bortkiewicz's Two Piano Sonatas, Op. 9 and Op. 60: A Comparison including Schenkerian Analysis and an Examination of Classical and Romantic Influences (open access)

The First Movements of Sergei Bortkiewicz's Two Piano Sonatas, Op. 9 and Op. 60: A Comparison including Schenkerian Analysis and an Examination of Classical and Romantic Influences

The purpose of this study is to analyze the first movements of Sergei Bortkiewicz's two piano sonatas and compare them with works by other composers that may have served as compositional models. More specifically, the intention is to examine the role of the subdominant key in the recapitulation and trace possible inspirations and influences from the Classical and Romantic styles, including Mozart, Beethoven, and Schubert. The dissertation employs Schenkerian analysis to elucidate the structure of Bortkiewicz's movements. In addition, the first movement of Mozart's Piano Sonata K. 545, Beethoven's Coriolan Overture, and the first movement of Schubert's "Trout" Quintet in A, D. 667, are examined in order to illuminate the similarities and differences between the use of the subdominant recapitulation by these composers and Bortkiewicz.

An Introduction to the Piano Works of William Mason (1829-1908) and a Performance Guide to Selected Repertoire for Intermediate Students (open access)

An Introduction to the Piano Works of William Mason (1829-1908) and a Performance Guide to Selected Repertoire for Intermediate Students

William Mason (1829–1908) was a well-known American composer, pianist, and pedagogue. Researchers have mainly focused on Mason's career as a pedagogue in the United States and his pedagogical treatises, which are widely considered and used as the conceptual core of teaching materials on the nineteenth century. However, there has been only an annotated catalogue of Mason's music works, and no performance guide to his piano compositions. This dissertation is designed to be the first performance guide to his solo piano repertoire and act as an introduction to his music through an examination of selected works suitable for the intermediate student. This study provides instruction for students on how to practice these works through the analysis of the elements of practice – pedaling, phrasing, technique practice, touch, and musical expression – which were all considered as essential by Mason himself for a good performance. The five piano works selected are: Three Preludes, Op. 8, No. 1; Ballade et Barcarole, Op. 15; Valse Caprice, Op.17; Spring-Dawn, Mazurka–Caprice, Op. 20; and Spring Flower–Impromptu, Op. 21.

Navigating Musical Tensions: African American Themes against Western Structure in Florence B. Price's (1887-1953) Piano Sonata in E minor (open access)

Navigating Musical Tensions: African American Themes against Western Structure in Florence B. Price's (1887-1953) Piano Sonata in E minor

Florence Price (1887–1953) was one of the most important African American woman composers of the early twentieth century. Price's music is known for combining techniques of Western art music with elements of the African American musical heritage. Although Price composed many works for piano, from large virtuoso pieces to characteristic miniatures, this study will address only her Piano Sonata in E minor. The purpose of this study is to analyze this sonata and discuss her compositional techniques and musical style as a combination of African American elements and Classical European procedures, combined and coordinated yet remaining in tension. Traditional European harmony, tonality, and form are successfully combined with African American characteristics: pentatonic scale, spirituals, syncopations, repetition, and dance rhythms. Indeed, Price's work is a considerable achievement, and she is one of the important African American women composers who should be better recognized today.

Near-Infrared Spectroscopy of High Redshift Quasars: Bringing Distant Quasars into View (open access)

Near-Infrared Spectroscopy of High Redshift Quasars: Bringing Distant Quasars into View

The Gemini Near Infrared Spectrograph - Distant Quasar Survey (GNIRS-DQS) is the largest uniform, homogeneous survey of its kind, covering 260 quasars at 1.5 ≤ z ≤ 3.5. This unique survey, coupled with data from the Sloan Digital Sky Survey (SDSS), enables new investigations into redshifts, supermassive black hole masses (MBH), and accretion rates at high redshift through spectroscopic coverage of important rest-frame UV-optical emission lines. The importance of this survey is highlighted in the fact that the optical emission lines provide more reliable measurements of these quasar parameters than their UV counterpart. With such a unique sample compiled here, I construct prescriptions to calibrate these quasar parameters derived from rest-frame UV emission lines to those derived from rest-frame optical emission lines. These prescriptions provide important insight into how these parameters depend on redshift and are potentially biased as we look out further into the universe. Additionally, all the work completed with this sample will help shape our understanding of how these quasars and their host galaxies co-evolve over cosmic time.

Inkjet Printed Transition Metal Dichalcogenides and Organohalide Perovskites for Photodetectors and Solar Cells

This dissertation is devoted to the development of novel devices for optoelectronic and photovoltaic applications using the promise of inkjet printing with two-dimensional (2D) materials. A systematic approach toward the characterization of the liquid exfoliated 2D inks comprising of graphene, molybdenum disulfide (MoS2), tungsten diselenide (WSe2), and 2D perovskites is discussed at depth. In the first study, the biocompatibility of 2D materials -- graphene and MoS2 -- that were drop cast onto flexible PET and polyimide substrates using mouse embryonic fibroblast (STO) and human esophageal fibroblast (HEF) cell lines, was explored. The polyimide samples for both STO and HEF showed high biocompatibility with a cell survival rate of up to ~ 98% and a confluence rate of 70-98%. An inkjet printed, biocompatible, heterostructure photodetector was constructed using inks of photo-active MoS2 and electrically conducting graphene, which facilitated charge collection of the photocarriers. The importance of such devices stems from their potential utility in age-related-macular degeneration (AMD), which is a condition where the photosensitive retinal tissue degrades with aging, eventually compromising vision. The biocompatible inkjet printed 2D heterojunction devices were photoresponsive to broadband incoming radiation in the visible regime, and the photocurrent scaled proportionally with the incident light intensity, exhibiting a …

Bohuslav Martinů's Oboe Concerto, H. 353: A New Piano Reduction of the Orchestral Score (open access)

Bohuslav Martinů's Oboe Concerto, H. 353: A New Piano Reduction of the Orchestral Score

Bohuslav Martinů's "Concerto for Oboe and Small Orchestra" is one of the most frequently played pieces in the oboe repertoire. For this reason, it is often played with the piano reduction instead of the orchestra in oboe recitals. However, the existing piano reductions include many errors and discrepancies from the orchestral score, misrepresent the orchestration, sometimes fail to make the oboe entries clear, and tend to be unplayable for pianists. Moreover, the scores were published after the composer's death without him supervising the final editing. I have prepared a new, playable piano reduction to represent the orchestration more faithfully and help pianists work with their soloists more easily. Based on the work of Martin Katz, a prominent collaborative-pianist, I establish four principles for creating a new piano reduction. After scrutiny of the deficiencies of existing piano reductions, I suggest solutions for making the passages in question practical and bringing out the leading voices clearly so that the soloist can join in as easily as playing with an orchestra. To aid in reflecting the orchestral texture that Martinů created, I include abbreviated instrument names in many passages to help pianists to understand how to create balance. I have changed some passages …

Multiomics Data Integration and Multiplex Graph Neural Network Approaches

With increasing data and technology, multiple types of data from the same set of nodes have been generated. Since each data modality contains a unique aspect of the underlying mechanisms, multiple datatypes are integrated. In addition to multiple datatypes, networks are important to store information representing associations between entities such as genes of a protein-protein interaction network and authors of a citation network. Recently, some advanced approaches to graph-structured data leverage node associations and features simultaneously, called Graph Neural Network (GNN), but they have limitations for integrative approaches. The overall aim of this dissertation is to integrate multiple data modalities on graph-structured data to infer some context-specific gene regulation and predict outcomes of interest. To this end, first, we introduce a computational tool named CRINET to infer genome-wide competing endogenous RNA (ceRNA) networks. By integrating multiple data properly, we had a better understanding of gene regulatory circuitry addressing important drawbacks pertaining to ceRNA regulation. We tested CRINET on breast cancer data and found that ceRNA interactions and groups were significantly enriched in the cancer-related genes and processes. CRINET-inferred ceRNA groups supported the studies claiming the relation between immunotherapy and cancer. Second, we present SUPREME, a node classification framework, by comprehensively …

A Pedagogical Guide to Teaching Tone Production for Elementary-Level Piano Students, with Examples from Appropriate Elementary-Level Music (open access)

A Pedagogical Guide to Teaching Tone Production for Elementary-Level Piano Students, with Examples from Appropriate Elementary-Level Music

The early stage of piano students' training is one of the most important, because it is then that they establish their habits for life. Those who teach beginners need clear principles for developing a solid technical foundation and for preventing bad technical habits. One of the most difficult principles to inculcate in young students is that of tone production and quality. The primary purpose of this study is to provide a pedagogical guide to help piano teachers teach tone production to elementary-level students. To accomplish this purpose, the strategies of the twentieth-century pedagogues Josef Lhévinne, Josef Hofmann, and Heinrich Neuhaus are examined, and applied to the elementary-level piano literature. This study offers practical training suggestions to teachers of elementary piano students as well as musical examples from high-quality piano literature to accompany these suggestions.

Factors Impacting Multicultural Teaching Competence among Counselor Educators: Ethnic/Racial Identity Development and Social Justice Orientation (open access)

Factors Impacting Multicultural Teaching Competence among Counselor Educators: Ethnic/Racial Identity Development and Social Justice Orientation

Multicultural (MC) counseling and social justice (SJ) are foundational parts of counselors' professional identity, and they are fostered through a developmental process that counselor educators facilitate. The purpose of this study was to explore the relationship between counselor educators' ethnic/racial identity development (ERI), their social justice orientation (SJO) and their multicultural teaching competence (MCTC). MCTC was examined using the constructs of knowledge and sensitivity. Data was collected from a nationally distributed online survey. Data were analyzed using four hierarchical regression models in order to control for socially desirable responding. Results indicated that ERI was a significant predictor of MCTC-Knowledge (p < .001) and that SJO was a significant predictor of MCTC-Sensitivity (p < .001). Socially desirable responding was not significantly related to MCTC. Results suggest the importance of attending to ERI and SJO as separate processes in training future counselor educators.

Placing High-Redshift Quasars in Perspective: Unifying Distant Quasars with Their Lower Redshift Counterparts through Near-Infrared Spectroscopy

I present spectroscopic measurements for 260 sources from the Gemini Near Infrared Spectrograph–Distant Quasar Survey (GNIRS-DQS). Being the largest uniform, homogeneous survey of its kind, it represents a flux-limited sample of Sloan Digital Sky Survey (SDSS) quasars at 1.5 < z < 3.5. A combination of the GNIRS and SDSS spectra covers principal quasar diagnostic features, chiefly the C IV λ1549, Mg II λλ2798, 2803, Hβ λ4861, and [O III] λλ4959, 5007 emission lines, in each source. The spectral inventory is utilized primarily to develop prescriptions for obtaining more accurate and precise redshifts, black hole masses, and accretion rates for all quasars. Additionally, the measurements facilitate an understanding of the dependence of rest-frame ultraviolet–optical spectral properties of quasars on redshift, luminosity, and Eddington ratio, and test whether the physical properties of the quasar central engine evolve over cosmic time.

The Role of Interface in Crystal Growth, Energy Harvesting and Storage Applications (open access)

The Role of Interface in Crystal Growth, Energy Harvesting and Storage Applications

A flexible nanofibrous PVDF-BaTiO3 composite material is prepared for impact sensing and biomechanical energy harvesting applications. Dielectric polyvinylidene fluoride (PVDF) and barium titanate (BaTiO3)-PVDF nanofibrous composites were made using the electrospinning process based on a design of experiments approach. The ultrasonication process was optimized using a 2k factorial DoE approach to disperse BaTiO3 particles in PVDF solution in DMF. Scanning electron microscopy was used to characterize the microstructure of the fabricated mesh. The FT-IR and Raman analysis were carried out to investigate the crystal structure of the prepared mesh. Surface morphology contribution to the adhesive property of the composite was explained through contact angle measurements. The capacitance of the prepared PVDF- BaTiO3 nanofibrous mesh was a more than 40% increase over the pure PVDF nanofibers. A comparative study of dielectric relaxation, thermodynamics properties and impact analysis of electrospun polyvinylidene fluoride (PVDF) and 3% BaTiO3-PVDF nanofibrous composite are presented. The frequency dependent dielectric properties revealed micro structural features of the composite material. The dielectric relaxation behavior is further supported by complex impedance analysis and Nyquist plots. The temperature dependence of electric modulus shows Arrhenius type behavior. The observed non-Debye dielectric relaxation in electric loss modulus follows a thermally activated process which …
