Exploring Modernist Traits In The Guitar Works Of Manuel María Ponce, Michael William Bunny
Exploring Modernist Traits In The Guitar Works Of Manuel María Ponce, Michael William Bunny
Theses and Dissertations
Music of the early twentieth century developed drastically from that of previous eras. With Debussy’s emphasis on tone color and timbre, Stravinsky’s rhythmic complexities, and Bartók’s incorporation of folk music, the twentieth century had a far different sound to that which preceded it. Each of these composers demonstrated different practices of this new genre called modernism. However, likely due to Andrés Segovia’s dislike of modernist music, there were not many popular composers that followed this trend in the guitar world. Those composing for the guitar shied away from attributes of modernism, ensuring that their works would be played. Manuel María …

Unaccompanied Double Bass Literature: History, Pedagogy, And Performance Practice, Joseph Lee Gaskins
Unaccompanied Double Bass Literature: History, Pedagogy, And Performance Practice, Joseph Lee Gaskins
Theses and Dissertations
While most solo recitals featuring the double bass employ the piano as accompaniment, this ensemble configuration presents several problems for the performer in terms of balance and sound production. These challenges can cause students who are still developing their technique and musicianship to form bad habits in an effort to meet the demands of playing with piano. Over time, double bassists have developed a multitude of strategies to solve the problem of projecting a soloistic sound that will project over the accompaniment. However, the question must be asked: Why not remove the accompaniment from the equation entirely? While the double …
Child-Caregiver Relational Closeness And Child Mental Health In Nonparental Care Settings, Amanda Stafford Mcrell
Child-Caregiver Relational Closeness And Child Mental Health In Nonparental Care Settings, Amanda Stafford Mcrell
Theses and Dissertations
This dissertation examines child-caregiver relational closeness and child mental health within nonparental care systems in Low- and Middle-Income countries (LMICs). Five key factors impacting the well-being of orphaned, separated, and vulnerable children in LMICs are explored using the Positive Outcomes for Orphans (POFO) dataset: child maltreatment, social support, child-caregiver relationships, and nonparental care systems. First, I examined the relationship between maltreatment, social support, and mental well-being. Findings showed that maltreatment was associated with lower mental well-being, where social support (emotional support, tangible support, positive social support) was associated with greater mental well-being, even in the concurrent presence of maltreatment. Second, …

Hallucinations In Large Foundation Models: Characterization, Quantification, Detection, Avoidance, And Mitigation, Vipula Rawte
Hallucinations In Large Foundation Models: Characterization, Quantification, Detection, Avoidance, And Mitigation, Vipula Rawte
Theses and Dissertations
Deception is an inherent aspect of social interactions, with research indicating that most people engage in deceptive behavior at least once or twice daily . In parallel, advances in artificial intelligence have led to machines exhibiting deceptive tendencies. These deceptions can be categorized into two types: unintended and intentional. Unintended deceptions - often referred to as hallucinations - occur when generative AI systems produce plausible and convincing narratives yet are factually inaccurate. This phenomenon primarily results from the systems' architectural design, extensive parametric memory, and reliance on statistical assumptions. In this thesis, we provide a comprehensive discussion on the characterization, …
Translating Theory Into Practice: Mediating Academic Advising Reform At Scale Through Improvement Science, Joshua Black
Translating Theory Into Practice: Mediating Academic Advising Reform At Scale Through Improvement Science, Joshua Black
Theses and Dissertations
Improving student outcomes at community colleges is a difficult, multifaceted problem. While no single approach can be a panacea for such a challenging problem of practice, Guided Pathways (GP) research suggests a scalable reform model that may ultimately help to improve the underlying systems and structures colleges have designed to support their students, and in turn, may help colleges to achieve the goal of improved student outcomes more consistently. Because of the breadth of the GP model’s recommendations for reform, however, implementation is complex. To be effective, each of the reforms must be localized, adopted, and brought to scale within …

The Impact Of Ballet Techniques On Singing Performers, Julie H. Welch
The Impact Of Ballet Techniques On Singing Performers, Julie H. Welch
Theses and Dissertations
Singing performers are tasked to being a multifaceted artist using their acting and even dance skills in a performance. Voice teachers have long incorporated physical activity into training, but traditional ballet techniques—such as core tension and neck elongation—can contradict healthy singing practices. Given ballet’s deep historical connection to opera and stage performance, this study aims to examine whether integrating ballet into vocal training enhances or hinders a singer’s technique and overall performance. This investigation surveyed forty subjects who identified as teachers, singing performers, or students earning a performance degree and interviewing select subjects for further information; results will be discussed.

A Multifaceted Perspective Of Scaling Entrepreneurial Innovation And Impact In Developing Country Contexts, Chanyong Yoo
A Multifaceted Perspective Of Scaling Entrepreneurial Innovation And Impact In Developing Country Contexts, Chanyong Yoo
Theses and Dissertations
This paper redefines the understanding of venture scaling in emerging and developing countries through a longitudinal case study of over a decade of transformative growth by Gojek, a local venture in Indonesia. Contrary to the replication logic common among global players—which prioritizes rapid and broader market opportunity expansion using a single, proven business model—Gojek adopted a more incremental and depth-oriented approach. By identifying untapped local demands and developing new market opportunities through stacking different business models, Gojek generated both demand- and supply-side complementarities within its business model portfolio that led to subsequent scaling. The findings suggest that scaling in developing …
Exploiting Structures In Reinforcement Learning: Multi-Agent Homogeneity, Euclidean Symmetry, And Natural Languages, Dingyang Chen
Exploiting Structures In Reinforcement Learning: Multi-Agent Homogeneity, Euclidean Symmetry, And Natural Languages, Dingyang Chen
Theses and Dissertations
Reinforcement learning (RL) has emerged as a powerful paradigm for decision-making in complex environments. However, many RL tasks exhibit inherent structural properties—such as homogeneity, symmetry, and linguistic patterns—that are often underutilized, leading to inefficiencies in learning and generalization. This dissertation systematically exploits these structures to improve the efficiency, scalability, and robustness of RL algorithms across multi-agent and sequential decision-making settings. First, we investigate homogeneity in multi-agent systems, where agents share similar roles and objectives. By leveraging this structure, we develop communication-efficient actor-critic methods for homogeneous Markov games, enabling scalable learning with reduced coordination overhead. Second, we introduce Euclidean symmetry in …
Reclaiming The Body: Gender Politics And Embodied Meaning In Piano Performance And Pedagogy, Rachel Misheff
Reclaiming The Body: Gender Politics And Embodied Meaning In Piano Performance And Pedagogy, Rachel Misheff
Theses and Dissertations
This study examines the impact of the mind-body duality and its gendered metaphor on the lived experiences of historical and contemporary female pianists. Specifically, it explores how the principles of mind-body dualism have constructed gendered practices in piano performance and pedagogy that have both marginalized female pianists and engendered distinct embodied relationships to music. The study draws upon research from other disciplines, such as phenomenology, theories of embodiment, feminist theory, psychoanalysis, and Embodied Music Cognition, to examine how these gendered musical norms resulting from mind-body dualism functioned as forces of social inscription. This research, therefore, suggests that the body’s lived …
