Adaptive Resonance Associative Map: A Hierarchical ART System for Fast Stable Associative Learning

This paper introduces a new class of predictive ART architectures, called Adaptive Resonance Associative Map (ARAM) which performs rapid, yet stable heteroassociative learning in real time environment. ARAM can be visualized as two ART modules sharing a single recognition code layer. The unit for recruiting a recognition code is a pattern pair. Code stabilization is ensured by restricting coding to states where resonances are reached in both modules. Simulation results have shown that ARAM is capable of self-stabilizing association of arbitrary pattern pairs of arbitrary complexity appearing in arbitrary sequence by fast learning in real time environment. Due to the symmetrical network structure, associative recall can be performed in both directions.

The impacts of past land-use on the ecology of an ancient woodland in south-west Ireland

A multi-disciplinary study was conducted to compare stands of ancient and secondary origin within a single wood, the Gearagh woodland, County Cork. These sites were compared with adjacent areas of grassland, which provided a reference for the former land-use (pasture) of the secondary woodland. A historical study confirmed that while the core of the Gearagh has been subject to minimal human interference, other sections have been cleared in the past for agricultural purposes. Investigations into soil structure and composition showed that soil properties in these secondary woodland areas were significantly altered by this past woodland clearance and conversion to agriculture, while the soil of the ancient woodland showed little signs of disturbance. The vegetation community also differed between the two woodland areas, partly due to altered environmental conditions. Many of the ancient woodland plant species were unable to form a persistent seed bank, while there was increased representation of species associated with more open-habitat conditions in the seed bank of the secondary woodland. While germination of woodland species was low in all sites, overall, seeds tended to germinate more successfully in the ancient woodland. The ancient woodland also provided a suitable habitat for many soil and ground detritivores, most notably enchytraeids, although earthworms were not abundant. Past agricultural use, however, changed the decomposer community considerably, with increased representation of earthworm species and a decline in the abundance of enchytraeids in the secondary stands. In conclusion, the legacies of historical agricultural activities can continue to significantly affect the structure and composition of present-day woodlands so that they may differ considerably from undisturbed ancient woodland stands, even within the same woodland. A greater understanding of the origin, development and ecological functioning of ancient woodlands should aid in determining future conservation and management requirements.

The examination of the traditional femininity and women’s lives in ancient China

This thesis explores the evolution of the concept of traditional Chinese femininity in relation to women’s lives in ancient China (221 BCE – A.D.1840). It proposes that the traditional Chinese femininity had been trying to seek a balance between the permanent principles and contingency plans for the stability and development of the society, which caused women’s humiliation and freedom. In reality, politicians and thinkers in ancient China had been transforming the concept of femininity itself to make it more adaptable to the social conditions of that time. This may be discussed in terms of three aspects. Firstly, the traditional concept of Chinese human relationships, including the ethical order, always emphasised the influence of individual behaviour on others and the overall stability and linked development of family, society and nation. Thus, both men and women, must be placed within this interrelated, interacting and cooperating relationship. Secondly, the association of family and country created an overlap of family and public affairs, which, objectively, facilitated the movement of women from the inner to the public arena. Thirdly, the notions of political and ethical morality and of men’s virtues and women’s virtues were integrated because of the union of family and nation. Therefore, typically virtuous women could be a source of encouragement for men and, furthermore, men formulated their virtues in the public space by formulating women’s virtues in the private space. The shaping of the gender image and concept of women in ancient China reflected the country’s changing cultural and gender norms. Chinese femininity and lifestyles, like Chinese history, were a continuous presence in the society but were also constantly changing. Through this study, it could be noted that Chinese women were not hidden and that their subjectivity and the concepts motivating them were not merely devised by a male-dominated society and culture.

The architecture of influence: Paul Rudolph's Art and Architecture Building at Yale

Focussing on Paul Rudolph’s Art & Architecture Building at Yale, this thesis demonstrates how the building synthesises the architect’s attitude to architectural education, urbanism and materiality. It tracks the evolution of the building from its origins – which bear a relationship to Rudolph’s pedagogical ideas – to later moments when its occupants and others reacted to it in a series of ways that could never have been foreseen. The A&A became the epicentre of the university’s counter culture movement before it was ravaged by a fire of undetermined origins. Arguably, it represents the last of its kind in American architecture, a turning point at the threshold of postmodernism. Using an archive that was only made available to researchers in 2009, this is the first study to draw extensively on the research files of the late architectural writer and educator, C. Ray Smith. Smith’s 1981 manuscript about the A&A entitled “The Biography of a Building,” was never published. The associated research files and transcripts of discussions with some thirty interviewees, including Rudolph, provide a previously unavailable wealth of information. Following Smith’s methodology, meetings were recorded with those involved in the A&A including, where possible, some of Smith’s original interviewees. When placed within other significant contexts – the physicality of the building itself as well as the literature which surrounds it – these previously untold accounts provide new perspectives and details, which deepen the understanding of the building and its place within architectural discourse. Issues revealed include the importance of the influence of Louis Kahn’s Yale Art Gallery and Yale’s Collegiate Gothic Campus on the building’s design. Following a tumultuous first fifty years, the A&A remains an integral part of the architectural education of Yale students and, furthermore, constitutes an important didactic tool for all students of architecture.

Visual Disobedience: The Geopolitics of Experimental Art in Central America, 1990-Present

This dissertation centers on the relationship between art and politics in postwar Central America as materialized in the specific issues of racial and gendered violence that derive from the region's geopolitical location and history. It argues that the decade of the 1990s marks a moment of change in the region's cultural infrastructure, both institutionally and conceptually, in which artists seek a new visual language of experimental art practices to articulate and conceptualize a critical understanding of place, experience and knowledge. It posits that visual and conceptual manifestations of violence in Central American performance, conceptual art and installation extend beyond a critique of the state, and beyond the scope of political parties in perpetuating violent circumstances in these countries. It argues that instead artists use experimental practices in art to locate manifestations of racial violence in an historical system of domination and as a legacy of colonialism still witnessed, lived, and learned by multiple subjectivities in the region. In this postwar period artists move beyond the cold-war rhetoric of the previous decades and instead root the current social and political injustices in what Aníbal Quijano calls the `coloniality of power.' Through an engagement of decolonial methodologies, this dissertation challenges the label "political art" in Central America and offers what I call "visual disobedience" as a response to the coloniality of seeing. I posit that visual colonization is yet another aspect of the coloniality of power and indispensable to projects of decolonization. It offers an analysis of various works to show how visual disobedience responds specifically to racial and gender violence and the equally violent colonization of visuality in Mesoamerica. Such geopolitical critiques through art unmask themes specific to life and identity in contemporary Central America, from indigenous genocide, femicide, transnational gangs, to mass imprisonments and a new wave of social cleansing. I propose that Central American artists--beyond an anti-colonial stance--are engaging in visual disobedience so as to construct decolonial epistemologies in art, through art, and as art as decolonial gestures for healing.

BOULANGER, SATIE, AND DEBUSSY: THEIR SPHERES OF INFLUENCE ON FRENCH MELODIE AND AMERICAN ART SONG

This dissertation project explored the spheres of influence on art song by Nadia Boulanger, Erik Satie, and Claude Debussy within Boulangeries, Les Six, and Les Apaches. After World War I, American composers flocked to Paris to study with Boulanger. Boulanger gave her students the confidence to explore their native talents instead of mimicking foreign models. Works by Aaron Copland, Virgil Thomson, Theodore Chanler, John Duke, and Richard Hundley were included in the first dissertation recital on January 31, 2010: The Legacy of Nadia Boulanger: Her Influence on American Song Composers. Satie established a new modern French musical style, and was a catalyst for the formation of Les Six. Ned Rorem came to Paris, and had a close association with Les Six. Works by Satie, and three members of Les Six, Francis Poulenc, Arthur Honegger, Darius Milhaud; and Rorem were featured in the second recital on September 1, 2010: Satie, Selected Members of Les Six, and Rorem in Paris. Debussy was one of the most significant French composers in the late nineteenth century, predating Boulanger and Satie. Young composers exploring new directions were inspired by Debussy, forming the group Les Apaches. The final recital, April 7, 2011, featured works by Debussy and two members of Les Apaches, Maurice Ravel and Manuel de Falla: Debussy: A Catalyst for Les Apaches, Ravel and Falla. Falla‘s less well-known repertoire was presented. This dissertation showed the influence of these three major figures and that they embraced innovation in their own time, along with their followers. Recordings of these three performances may be obtained from the Michelle Smith Performing Arts Library in Clarice Smith Performing Arts Center at the University of Maryland, College Park.

THE ART SONG OF SOUTH AMERICA: AN EXPLORATION THROUGH PERFORMANCE

The repertoire included in this dissertation was presented over the course of three recitals, The Songs of Argentina, The Songs of Brazil, Chile and Venezuela, and The Songs of Perú and Colombia. Each recital was supplemented by written program notes and English translations of the Spanish, Portuguese and Quechua texts. The selections presented in this study was chosen in an effort to pair the works of internationally renowned composers like Argentine composers Alberto Ginastera and Carlos Guastavino, and Brazilian composer Heitor Villa-Lobos, with those of lesser-known composers, including Venezuelan composer Juan Bautista Plaza, Peruvian composers Edgar Valcárcel, Theodoro Valcárcel, and Rosa Mercedes Ayarza de Morales, and Colombian composer Jaime Léon. Each composer represents a milestone in the development of art song composition in South America. All three recitals were recorded and are available on compact discs in the Digital Repository at the University of Maryland (DRUM). This dissertation was completed in May, 2011.

THE ART OF TRANSCRIBING FOR HARPSICHORD

A relatively unexplored area of the harpsichord repertoire is the group of transcriptions made by J.S. Bach (1685-1750), Jean Henry d'Anglebert (1629-1691), and Jean-Baptiste Forqueray (1699-1782). These transcriptions are valuable and worth exploring and performing. Studying them provides unique insights into their composer‘s musical thinking. By comparing transcriptions with their original sources, the transcriber's decisions and priorities can be observed. The performance component of this dissertation comprises three recitals. The first features works of Johann Sebastian Bach: two transcriptions of violin concerti by Antonio Vivaldi (1678-1741), and two transcriptions of trio sonatas by Johann Adam Reinken (1643-1722). The most salient feature of Bach‘s transcriptions is his addition of musical material: ornamenting slow movements, adding diminutions and idiomatic keyboard figurations throughout, and recomposing and expanding fugal movements. The second recital features works of Jean Henry d'Anglebert and Jean-Baptiste Forqueray, two French composer/performers. From d'Anglebert‘s many transcriptions, I assembled two key-related suites: the first comprised of lute pieces by Ennemond Gaultier (c. 1575-1651), and the second comprised of movements from operas by Jean-Baptiste Lully (1632-1687). Forqueray's transcriptions are of suites for viola da gamba and continuo, composed by his father, Antoine Forqueray (1671-1745). Creative and varied ornamentation, along with the style brisé of arpeggiated chords, are the most important features of d‘Anglebert‘s transcriptions. Forqueray‘s transcriptions are highly virtuosic and often feature the tenor and bass range of the harpsichord. The third recital features my own transcriptions: the first suite for solo cello by J.S. Bach, excerpts from the opera La Descente d’Orphée aux Enfers by Marc-Antoine Charpentier (1643-1704), and two violin pieces by Nicola Matteis (fl. c. 1670-c. 1698). In these transcriptions, I demonstrate what I have learned from studying and performing the works in the first two recitals. These recitals were performed in the Leah Smith Hall at the University of Maryland on May 4, 2010; May 11, 2010; and October 7, 2010. They were recorded on compact discs and are archived within the Digital Repository at the University of Maryland (DRUM).

PIANO AS A PARTNER IN TWENTIETH­ CENTURY ART SONG REPERTOIRE: A RECORDING PROJECT

The piano's role in art song repertoire has evolved from a modest one during its formative years to the versatility, complexity and creativity found in the twentieth-century. The art song repertoire of the twentieth century is vast and has secured the reputation for being the most diverse, innovative, illustrative, atmospheric and colorful in all of art song literature. Within this time period, there are compositions that reach back to the romantic works of nineteenth century, others which combine old and new traditions, and finally those which adopt new means and new ends. In choosing the material for this project, I have focused on compositions with uniquely challenging and unusual piano accompaniments in order to achieve a balance between well- known and rarely performed works, as well as those pieces that combine various languages and styles. Selections range from Claude Debussy, Richard Strauss, Sergey Rachmaninoff, Ralph Vaughan Williams, Roger Quilter, Francis Poulenc, Fernando Obradors, and Joaquin Rodrigo to composers such as Samuel Barber, Marc Blitzstein, Dominick Argento, William Bolcom, and John Duke, including arrangements of traditional spirituals by Harry T. Burleigh and Florence B. Price, all of which helped to establish the American Art Song. My objective is to trace the development of the twentieth-century art song from the late Romantic Period through nationalistitrends to works which show the influences of jazz and folk elements. The two CD's for this dissertation recording project are available on compact discs which can be found in the Digital Repository at the University of Maryland (DRUM). The performers were Daniel Armstrong, baritone, Giles Herman, baritone, Thomas Glenn, tenor, Valerie Yinzant, soprano, Aaron Odom, tenor, Jennifer Royal, soprano, Kenneth Harmon, tenor, Karen Sorenson, soprano and Maxim Ivanov, baritone.

FOLK ELEMENTS IN TWENTIETH-CENTURY HUNGARIAN MUSIC

At the beginning of the twentieth century, composers Béla Bartók and Zoltán Kodály collected thousands of folksongs from the rural regions of Hungary. In an effort to preserve a part of their culture that they feared would be lost, they not only transcribed and catalogued these folksongs, but also incorporated the folk traditions they encountered into their own compositional style. This dissertation deals with violin music written by Bartók, Kodály and their Hungarian contemporaries that have in common the use of rhythms, modes, melodies, figurations and playing techniques sourced in folk traditions. The use of the Hungarian folk idiom in classical music was not exclusive to the twentieth century. From the late eighteenth century until the first decades of the twentieth century, composers utilized aspects of a popular eighteenth-century form of Hungarian folk music called verbunkos. What makes the use of folk music unique in the twentieth century is that, thanks to the work of Bartók and Kodály, composers found inspiration in the more authentic “peasant music.” Unlike the popular, urban verbunkos music, peasant music was the product of the more secluded village-music tradition, largely untouched by the influences of city life. In addition to stimulating a new focus on peasant music, Bartók and Kodály fully assimilated the folk idiom into their compositional toolkits, creating a new style of folk-inspired art music that influenced a generation of Hungarian composers. The new style included characteristic elements of both peasant music and the verbunkos tradition, such as ancient modes and scales, accompanimental and melodic rhythmic patterns, ornamentation, and phrase structures sourced in folk song. To demonstrate the implementation of the folk idiom by twentieth-century Hungarian composers, three recital programs were given at the University of Maryland that included works by Béla Bartók, Sándor Veress, Leo Weiner, Zoltán Kodály, Ernő Dohnányi, Zoltán Székely and György Kurtág. The works can be divided into two main categories: settings or transcriptions of folk material (e.g. Bartók’s Hungarian Folksongs) and compositions using classical forms that include the Hungarian folk idiom (e.g. Bartók’s Contrasts). Recital collaborators include Li-Tan Hsu, Evelyn Elsing, Elizabeth Brown, Shelby Sender and Samantha Angelo.

LUCIANO BERIO’S NATURALE: A STORY COMBINING FOLK MUSIC AND ART MUSIC

The study of a score by a serious performer is a fundamental step in the process of arriving at a knowledgeable and deeply informed approach to performing a piece of music. In order to obtain this knowledge numerous aspects of the score must be taken into consideration. It is the intent of this dissertation to gather and analyze the information concerning Naturale, a work written by Luciano Berio in 1985 for viola, percussion and recorded voice, based on Sicilian folk songs. All the aspects surrounding Naturale’s existence are taken into consideration in this study. First, it is important to reflect on Berio’s compositional style and traits, the manner in which he relates his works one to another, what he sees in folk music and his own personal desire to intertwine art music and folk music. For Berio Naturale is not an isolated venture into the realm of mixing folk music and his own avant-garde style; it is instead one of many works resulting from his long-standing relationship with folk music. Another essential aspect in this case is the study of Sicilian folk music itself, and the sources used by Berio to find the songs by which he was inspired. The work is examined section by section with figures showing both excerpts of Naturale as well as the original songs with their translations. An analysis containing harmonic, thematic and formal aspects of the score was developed in order to arrive at a better understanding of the structure and pacing of the piece. For this research the author went to Italy to conduct an interview with Maestro Aldo Bennici, the Sicilian violist for whom Naturale was composed. This interview helped in the discovery of two more songs used by Berio that have not to this point been identified in any other document. Bennici’s outstanding testimony portrayed the expressive character of this music and the evocative imagery behind this score. I hope to bring this knowledge to other performers, that they may fully understand and appreciate the unique beauty and power of Berio’s Naturale.
