The twentieth century has witnessed a renaissance in the composition of choral music. Not since the Baroque, has choral writing held the prominent position with composers that it has today. At the same time, English composers have regained a stature and influence they have not held since the time of Purcell. It was not until the time of Edward Elgar, Gustave Holst, and Ralph Vaughn-Williams that English music began to recover from the decline of the nineteenth century. Benjamin Britten has played a large role in both the choral renaissance and the recovery of English music.

Virtually disregarded in contemporary discussions of cello performance and pedagogy is the name of Luigi Silva (1903-1961). Though he did not achieve fame as a performer to the same degree as his peers Leonard Rose (1918-1984), Emanuel Feuermann (1902-1942) or Gregor Piatigorsky (1903-1976), Silva had an internationally-acclaimed performing career. Owing to his formidable technique on the instrument, he was known as the "Paganini of the cello." Through Silva's unparalleled ability to analyze technical problems in his students' playing and assist his student have populated faculties of most of the major American post-secondary schools of music and many of the principal chairs in important symphony orchestras. Of even longer-lasting significance is his enormous contribution to the literature for cello of over 100 transcriptions and scholarly editions of standard cello repertoire. By combining his own incredible artistry on the instrument and his extraordinary enthusiasm for teaching with his transcriptions of such works as the 24 Paganini Caprices, Silva helped raise the standard of cello technique to an unprecedented level and has impacted in one way or another every cellist in the twentieth century. This dissertation document describes the influences Silva's transcriptions and editions have had on cello playing and teaching in the 20th-Century.

This fascinating new book, Venice, Cita Excelentissima, contains a series of translated excerpts from the diaries of the Venetian patrician Marin Sanudo (1466-1536). Sanudo wrote his vast diaries between 1496 and 1533. As early as Sanudo's own lifetime, historians used the richness and variety of these diaries as an unparalleled evidentiary source for early modern Venice. The depth of the diaries derives from Sanudo's personal access to govern ment records and, perhaps even more, his attention to detail and the wide range of topics that he deemed worthy of record. The importance of the diaries prompted a group of Italian editors to publish them in their entirety between 1879 and 1903, a project that eventually spanned fifty-eight volumes. E

In this thesis, a comprehensive understanding of supervised machine learning algorithms, namely Logistic Regression, Support Vector Machine, Random Forest, and Ensemble Stacking, is performed. This research also extends and further explores different feature selection techniques: correlation analysis, chi-squared, mutual information classification, and Recursive Feature Elimination (RFE). Then, a practical application in the context of coronary artery disease prediction was conducted to apply and analyze models' performance with different feature selection methods on various measures of accuracy, F1 score, and confusion matrix. The outcomes of this experimentation reveal that among models developed, Logistic Regression with chi-squared feature selection is a robust and reliable predictive model, achieving an accuracy of 87.65%. This research advances the understanding of machine learning algorithms and feature selection techniques, with practical implications for reliable prediction of coronary artery disease.

The lecture was presented April 7, 1987. This presentation centered on the flute music literature used for the Concours of the Conservatoire de Paris from 1828 through 1893. The historical parameter began with Jean-Louis Tulou's tenure as flute professor at the Conservatoire and ended with Joseph-Henri Altes'tenure in the same capacity. The Concours is an annual performance competition to determine which students on each instrument will graduate from the Conservatoire. The majority of Concours pieces for flute during the tenures of professors from Tulou through Altes were composed by those two men. Short biographies of Tulou and Altes were presented. Discussion of interim professors Victor Coche and Vincent-Joseph Dorus was included, with focus on the role of these two men in bringing acceptance of the Boehm system flute to the Conservatoire. Tulou's fifteen Grands Solos were compared in form, key center and tonal progression. His themes and passagework are constructed to best display the conical-bore, old system-flute with small toneholes. His Solos continued to be used for the Concours, in alternation with Altes', throughout the tenures of both Vincent-Joseph Dorus and Altes. Tulou's Cinquieme Grand Solo was used for more detailed analysis and performance. Altes wrote his Solos de Concours for the Boehm system flute. Idiomatic treatment in composition of themes and passagework, as well as tonal progression in his Solos, was considered. Altes' Methode de flute reveals his views on variety in articulation, use of alternate fingerings, and musical interpretation. Those ideas are reflected in the construction of his Cinquieme Solo de ronrnwr. the example used for more detailed analysis and performance. The discussion was concluded by a comparison of the Solos of Tulou and Altes with regard to form, tonal progression, and idiomatic construction of themes and passagework.

O milho de segunda safra, também conhecido como milho safrinha, é definido como aquele semeado entre os meses de janeiro e março. Esta modalidade de cultivo atingiu no ano agrícola de 2013/2014 uma área plantada de 9,18 milhões de hectares, superior a área cultivada com milho primeira safra, que no mesmo período foi de 6,61 milhões de hectares. Na segunda safra, há alto risco de instabilidades climáticas, principalmente em decorrência de baixas temperaturas, geadas, má distribuição de chuvas e redução do fotoperíodo. Todos estes fatores prejudicam a atividade fotossintética do milho, reduzindo sua produtividade. No entanto, dada a importância deste cultivo, empresas públicas, privadas e universidades vêm buscando incrementar a produtividade e a estabilidade. Para isso, alguns caracteres são especialmente preconizados. Devido ao alto risco de perda por adversidades ambientais, muitos produtores investem pouco em adubação, principalmente adubação nitrogenada. Neste contexto, o desenvolvimento de plantas mais eficientes no uso e, ou, tolerantes ao estresse por nitrogênio, resultaria em maior segurança para o produtor. Não obstante, a precocidade tem elevada importância, já que materiais precoces reduzem o risco de perdas neste período. No entanto, a mesma deve estar sempre associada a alta produtividade. Assim, para a seleção simultânea destes caracteres, pode-se lançar mão de índices per se de resposta das plantas ao estresse, análises gráficas e, ou, índices de seleção simultânea. Adicionalmente, os valores genotípicos das linhagens para essas características, além de serem preditos via REML/BLUP single-trait (análise univariada), também podem ser preditos via REML/BLUP multi-trait (análise multivariada). Dessa forma, os valores genotípicos são corrigidos pela covariância existente entre os caracteres. Assim, o objetivo deste trabalho foi verificar a possibilidade de seleção simultânea para eficiência no uso e tolerância ao estresse por nitrogênio, além de plantas precoces e produtivas. Para isto, linhagens de milho tropical foram cultivadas e avaliadas para estes caracteres. Foram então simulados diversos cenários de seleção simultânea. A partir destes resultados, observou-se que o índice per se de resposta das plantas ao estresse Média Harmônica da Performance Relativa (MHPR) foi o mais eficiente na seleção de plantas eficientes no uso e tolerantes ao estresse por nitrogênio. Isto ocorreu devido a forte correlação desfavorável entre os índices que estimam a eficiência e a tolerância, além da superioridade e em acurácia, herdabilidade e ganhos com a seleção deste índice per se. Já para a seleção simultânea da produtividade e precocidade, o índice Aditivo de seleção simultânea, utilizando os valores genotípicos preditos via REML/BLUP single-trait se mostrou o mais eficiente, já que obteve ganhos satisfatórios em todos os caracteres e há a possibilidade de modular, de forma mais satisfatória, os ganhos em cada caractere. Conclui-se que a seleção simultânea tanto para eficiência no uso e tolerância ao estresse por nitrogênio, quanto para produtividade e precocidade são possíveis. Além disso, a escolha do melhor método de seleção simultânea depende da magnitude e do sentido da correlação entre os caracteres. / Second growing season maize, also known as winter maize, is the maize sowed in Brazil between January and March. This growing modality reached 9.18 million hectares in 2013/2014, higher than the area cultivated in first growing season that was 6.61 million hectares in the same period. In the second season, there is a high risk of climate instabilities, mainly due to low temperatures, frost, poor rainfall distribution and reduction of photoperiod. All these factors harm photosynthetic activity, reducing the maize yield. However, because of the recent plant area increasing, public, private companies and universities have sought increased yield and stability of the second growing season maize. For this, some traits are mainly in the selection process. With the high risk of yield loses due to environmental adversities, many farmers have done little investment in fertilizers, especially nitrogen fertilization. In this context, the development of plants that are nitrogen use efficient and nitrogen stress tolerant could result in a safer activity for the farmers. In addition, the earliness is highly important, since early materials reduce the risk of losses during this period. However, the earliness must always be associated with a high yield. This way, simultaneous selection of these traits can be made by per se responses indexes of stressed plants, graphical analysis and simultaneous selection indexes. Additionally, the genotypic values of the genotypes for the traits can be predicted not only by REML/BLUP single-trait (univariate analysis), but also by REML/BLUP multi-trait (multivariate analysis). In the second, the genotypic values are adjusted considering the covariance between the traits. This way, the objective of this study was to investigate the possibility of simultaneous selection for nitrogen use efficiency and nitrogen stress tolerance, as well as early and high yielding plants. For this, tropical maize lines were grown and evaluate. By these data, it was simulated several simultaneous selection sets. It was observed that Harmonic Mean of the Relative Performance (HMRP) is the most efficient in the selection for nitrogen use efficient and nitrogen stress tolerance. This probably occurs due to the strong unfavorable correlation between the indexes that estimate the efficiency and the tolerance, as well as the superiority in accuracy, heritability and selections gains of HMRP. In case of simultaneous selection for yield and earliness, the additive simultaneous selection index using the genotypic values predicted by REML/BLUP single-trait proved the most efficient selection, because it got satisfactory gains in all the traits and, this index allows the possibility to modulate the gains in each trait. It was concluded that the simultaneous selection for nitrogen use efficiency and nitrogen stress tolerance, as well as for yield and earliness are possible. Furthermore, the choice of the best simultaneous selection method depends on the magnitude and direction of the correlation between the traits.

The origin of the story of Narcissus is unknown, and the circumstances of his death are uncertain, but the most popular version of the tale as told by Ovid has been read, translated, explained, moralized and disputed by innumerable writers and alluded to by many more. Renaissance writers in England, such as Golding, Edwards and Sandys, were interested in first introducing the myth into their own language and then, in explaining its meanings, lessons and moralizations. Later poets paraphrased their translations, often adding their own point of view or else using only the skeleton structure of the myth for their own poetic purposes. The simple story of a youth who died by a pool after falling hopelessly in love with his own reflection acquired a significance and immortality worthy of a Greek god. The Eighteenth Century writers, who were less interested in the gods than their predecessors had been, almost completely ignored Narcissus in their poetry, but later poets such as Blake, Shelley and Keats revived him once again and transformed the faded youth into a Romantic. In The Book of Thel Blake explores the consequences of self-love, and anticipates the fuller development of this theme in The Four Zoas. He uses the archetypal pattern of the Narcissus myth for portraying the fading Thel, who refuses to enter the state of Generation because she is afraid of the voice of experience that she meets in her own grave when she descends into the underworld. Her sterile separation from her Spectre is similar to the unconsummated relationship between Narcissus and Echo. Thel fleeing from her grave escapes back to non-existence, fading by the river like Narcissus and Echo. An understanding of the function of the Narcissus story in Shelley's poem, Alastor, is indispensable to an interpretation of this controversial poem. Shelley's allusions to the myth are faithful to the Ovidian version of Narcissus as a youth who sighs away his life after seeing his own shadow in a well. Shelley associates the Poet's quest with the Narcissus myth by generally paralleling the narrative structure of Ovid's story, and by employing much of its imagery. Chapter II argues that Shelley's poem is both unified and consistent when it is interpreted in terms of the Narcissus theme. Keats primarily uses the popular myth of Endymion and Cynthia in his poem, Endymion, but also includes other myths in the manner of the Renaissance epyllion. The most significant addition to the main myth is the story of Narcissus as a comment on the nature of Endymion's quest. Keats pictures the hero at the well, viewing the reflection of the vision, in order to establish the specific parallel to Ovid's story. Endymion, however, unlike Narcissus or the Poet in Alastor, recognizes his illusion and proceeds towards accepting his responsibility to his kingdom and to the Echo figures in the poem. The analysis concludes with a comparison of the specific handling of the Narcissus myth in the three poems in terms of the various versions of the myth, the treatment of the metamorphosis of Narcissus Into a flower, and the development of the theme of self-love. The thesis establishes the significance of the Narcissus myth in The Book of Thel, Alastor and Endymion, and evaluates Blake's, Shelley's and Keats's contribution to the attempts of the Renaissance writers to introduce the Ovidian story into English literature. / Arts, Faculty of / English, Department of / Graduate
