Libby Larsen is one of the most performed and acclaimed composers today. She is a spirited, compelling, and sensitive composer whose music enhances the poetry of America's most prominent authors. Notable among her works are song cycles for soprano based on the poetry of female writers, among them novelist and poet Willa Cather (1873-1947). Larsen has produced two song cycles on works from Cather's substantial output of fiction: one based on Cather's short story, "Eric Hermannson's Soul," titled Margaret Songs: Three Songs from Willa Cather (1996); and later, My Antonia (2000), based on Cather's novel of the same title. In Margaret Songs, Cather's poetry and short stories--specifically the character of Margaret Elliot--combine with Larsen's unique compositional style to create a surprising collaboration. This study explores how Larsen in these songs delves into the emotional and psychological depths of Margaret's character, not fully formed by Cather. It is only through Larsen's music and Cather's poetry that Margaret's journey through self-discovery and love become fully realized. This song cycle is a glimpse through the eyes of two prominent female artists on the societal pressures placed upon Margaret's character, many of which still resonate with women in today's culture. This study examines the work Margaret Songs by discussing Willa Cather, her musical influences, and the conditions surrounding the writing of "Eric Hermannson's Soul." It looks also into Cather's influence on Libby Larsen and the commission leading to Margaret Songs. Finally, a description of the musical, dramatic, and textual content of the songs completes this interpretation of the interactions of Willa Cather, Libby Larsen, and the character of Margaret Elliot.

Puerto Rico has produced many important composers who have contributed to the musical culture of the nation during the last 200 years. However, a considerable amount of their music has proven to be difficult to access and may contain numerous errors. This research project intends to contribute to the accessibility of such music and to encourage similar studies of Puerto Rican music. This study focuses on the music of Héctor Campos Parsi (1922-1998), one of the most prominent composers of the 20th century in Puerto Rico. After an overview of the historical background of music on the island and the biography of the composer, four works from his art song repertoire are given for detailed examination. A product of this study is the first corrected edition of his cycles Canciones de Cielo y Agua, Tres Poemas de Corretjer, Los Paréntesis, and the song Majestad Negra. These compositions date from 1947 to 1959, and reflect both the European and nationalistic writing styles of the composer during this time. Data for these corrections have been obtained from the composer's manuscripts, published and unpublished editions, and published recordings. The corrected scores are ready for publication and a compact disc of this repertoire, performed by soprano Melliangee Pérez and the author, has been recorded to bring to life these revisions. Despite the best intentions of the author, the various copyright issues have yet to be resolved. It is hoped that this document will provide the foundation for a resolution and that these important works will be available for public performance and study in the near future.

Novel biological strategies for cancer therapy have recently been able to generate improved anti-tumor effects in the clinic. Of these new advancements, oncolytic virotherapy is a promising strategy through a dual mechanism of oncolysis and stimulation of tumor immunogenicity against the target cancer cells. Myxoma virus (MYXV) is an oncolytic poxvirus that has a natural tropism for Leporids, being nonpathogenic in humans and all other known vertebrates. MYXV is able to infect cancer cells due to mutations and defects in many innate signaling pathways, such as those involved in anti-viral responses. While MYXV alone infects and kills many classes of human cancer cells, recombinant techniques allow for the implementation of therapeutic transgenes, which have the potential of ‘arming’ the virus to enhance its potential as an oncolytic virus. The implementation of certain transgenes allows improved cancer cell killing and/or promotion of more robust anti-tumor immune responses. To investigate the potential of immune-inducing transgenes in MYXV, in vitro screening experiments were performed with several single transgene-armed recombinant MYXVs. As recent studies have shown the ability of MYXV to uniquely target malignant human hematopoietic stem cells, the potential of oncolytic MYXV armed with individual immune-enhancing transgenes was investigated through in vitro killing analysis using human acute myeloid leukemia (AML) and multiple myeloma (MM) cell lines. Additionally, in vitro experiments were performed using primary bone marrow (BM) cells obtained from human patients diagnosed with MM. Furthermore, the action of an engineered bispecific killer engager (huBIKE) was investigated through co-culture studies between the CD138 surface marker of target MM cells and the CD16 surface marker of primary effector peripheral blood mononuclear cells (PBMCs), particularly NK cells and neutrophils. In this study, several of the test armed MYXV-infected human AML and MM cell lines resulted in increased cell death compared to unarmed MYXV-infected cells. Additionally, increased killing of CD138+ MM cells from primary human BM samples was observed following infection with huBIKE-armed MYXV relative to infection with unarmed MYXV. Furthermore, analysis of co-culture studies performed suggests enhanced killing of target MM cells via engagement of NK cells with U266 MM cells by huBIKE.
