Bridging the Divide Between the Soloist and the Ensemble Player

In conservatories and music schools, the general practice for an aspiring pianist is to focus on solo performance learning mainly solo repertoire. With the advent of the advanced degree in collaborative piano, pianists could submerge themselves in the study of duo sonatas, larger chamber music ensembles, and art song. The appearance of this degree was an important step in the development of pianists, as this kind of work requires specific training and focus to master the vast repertoire involved. However it also more clearly brought out the invisible divide separating the solo pianist from the collaborative pianist, a.k.a. the accompanist. While geniuses such as Bach, Beethoven and Brahms were known to compose and perform all types of music, the appearance of super stars such as Liszt and Paganini helped bring into being the term accompanist and since then music world has tacitly embraced this divide. The goal of my dissertational study is to show that this divide need not exist. The three recitals which comprise this dissertational project were all performed at the University of Maryland, the first on 12 November 2010 at Gildenhom Recital Hall, the second at Ulrich Recital Hall on 10 September 2011, and the third at Gildenhorn Recital Hall on 11 November 2011. The repertoire included Rachmaninoff Prelude in g# minor op. 32 no. 12 and Etude-Tableaux in Eb minor op. 29 no. 5, Brahms Sonata for Piano and Violin in d minor op. 108, Mendelssohn Piano Trio in d minor op. 49, Chopin Sonata No.2 in Bb minor, Franck Sonata for Piano and Violin, Prokofiev Piano Concerto no. 2 in g minor op. 16 with pianist Elizabeth Brown as orchestra, Beethoven Sonata for Piano and Violin in A op 47 (Kreutzer), and Paul Schoenfield Cafe Music. All works with violin and cello were performed with violinist Rebecca Racusin, and cellist Devree Lewis. The recitals were recorded on compact discs and are archived within the Digital Repository at the University of Maryland(DRUM).

SELECTED TWENTIETH-CENTURY BRITISH & AMERICAN ENGLISH SONG REPERTOIRE WRITTEN FOR SOPRANO

English language song (both British and American) is influenced by a variety of cultures, races, and musical forms and has produced a broad range of song repertoire. Like songs in all countries and throughout history, these songs can be classified into three categories: imitative songs, experimental songs, and songs of individuality. Music experimentation, necessary and welcome as it is, can hardly command broad international attention. Thus, the songs of this dissertation performance project are chosen from the first and third categories: imitative songs and individual songs in the composer's own unique style. This project concentrates its exploration on twentieth-century solo songs written in English. Although twentieth-century British & American composers also produced solos and chamber music in other languages, this dissertation focuses upon their English repertoire. This performance project consists of three programs: one British repertoire and two American. The first program titled An Evening of British Song examines twentieth-century British song written by Roger Quilter, Peter Warlock, William Walton, Benjamin Britten, Thomas F. Dunhill, Ivor Gurney, and Frank Bridge. It was presented on December 12, 2001, in Homer Ulrich Recital Hall with the collaborative pianist Meriel Owen. The second program titled An Evening of American Song I comprises music written by Dominick Argento, Samuel Barber, Ned Rorem, Leonard Bernstein, and Lee Hoiby. It was presented on October 23, 2002, in Joseph & Alma Gildenhorn Recital Hall with the collaborative pianist R. Timothy McReynolds. The third program titled An Evening of American Song II written by John Duke, John Corigliano, Charles Ives, Richard Hundley, Lori Laitman, Frederick Loewe, George Gershwin, and Jerome Kern was presented on December 18, 2003, again in Joseph & Alma Gildenhorn Recital Hall with the collaborative pianist R. Timothy McReynolds and the flutist Jessica Dunnavant. Each of these three dissertation recitals occurred at the University of Maryland in College Park and was recorded. These CD recordings are held by the Michelle Smith Performing Arts Library at the University of Maryland.

Evaluating Alternative Nutrient Sources in Subsistence-Level Aquaponic Systems

Many food production methods are both economically and environmentally unsustainable. Our project investigated aquaponics, an alternative method of agriculture that could address these issues. Aquaponics combines fish and plant crop production in a symbiotic, closed-loop system. We aimed to reduce the initial and operating costs of current aquaponic systems by utilizing alternative feeds. These improvements may allow for sustainable implementation of the system in rural or developing regions. We conducted a multi-phase process to determine the most affordable and effective feed alternatives for use in an aquaponic system. At the end of two preliminary phases, soybean meal was identified as the most effective potential feed supplement. In our final phase, we constructed and tested six full-scale aquaponic systems of our own design. Data showed that soybean meal can be used to reduce operating costs and reliance on fishmeal. However, a more targeted investigation is needed to identify the optimal formulation of alternative feed blends.

The Impact of Prenatal Nicotine Exposure on Impulsivity and Neural Firing in the Medial Prefrontal Cortex

Prenatal nicotine exposure (PNE) is linked to a large number of psychiatric disorders, including attention deficit hyperactivity disorder (ADHD). Current literature suggests that core deficits observed in ADHD reflect abnormal inhibitory control governed by the prefrontal cortex (PFC) of the brain. The PFC is structurally altered by PNE, but it is still unclear how neural firing is affected during tasks that test behavioral inhibition, such as the stop-signal task, or if neural correlates related to inhibitory control are affected after PNE in awake behaving animals. To address these questions, we recorded from single medial PFC (mPFC) neurons in control rats and PNE rats as they performed our stopsignal task. We found that PNE rats were faster for all trial types and were less likely to inhibit the behavioral response on STOP trials. Neurons in mPFC fired more strongly on STOP trials and were correlated with accuracy and reaction time. Although the number of neurons exhibiting significant modulation during task performance did not differ between groups, overall activity in PNE was reduced. We conclude that PNE makes rats impulsive and reduces firing in mPFC neurons that carry signals related to response inhibition.
