A Lineage Of Contemporary Jazz Violin, Tsu Hao Kuo

Dissertations

The development of jazz violin has always been multifaceted. Not only has it followed the evolution of jazz, but it has also established its own parallel genres. Since the swing era, the violin no longer remains a top choice for jazz musicians as opposed to early jazz musicians who often doubled on string instruments. Intriguingly, the decline of its popularity in larger ensembles did not inhibit the growth of the jazz violin. Not only did jazz violinists thrive in small jazz ensembles, but its distinct blend with other string music genres also reached styles beyond the common narrative of jazz …

Lgbtq+ Adolescents With Disabilities’ Experiences Of School Connectedness And Identity Navigation, Lyndsay Loretta Mccabe

Dissertations

In the United States, LGBTQ+ students have recently faced a barrage of school-based anti-LGBTQ+ legislation and policies (American Civil Liberties Union, 2025). Little is known about the effects of such policies and the overall sociopolitical climate on school connectedness and identity navigation for LGBTQ+ adolescents with disabilities. School connectedness, or the degree to which students feel that they belong at their school, is associated with numerous academic, behavioral, and social-emotional benefits (K. Allen et al., 2018; Centers for Disease Control and Prevention [CDC], 2022b). Students who are at the intersection of multiple marginalized identities, such as LGBTQ+ adolescents with disabilities, …

Environmental Beliefs Among Evangelical Leadership, Jeffrey Stark

Dissertations

There has been consensus among climate scientists for over a decade about the reality of human caused climate change. Even with this consensus, the public understanding of this issue remains divided based on factors generally unrelated to the science. Evangelical Protestants are one group which consistently polls as more skeptical of climate change. This is true not only when compared to the general population but also when compared to other religious demographics. Most large-scale surveys of evangelicals assume the demographic to be a monolith and do not attempt to break the demographic down further. In this mixed methods study, we …

Molecular Design And Engineering Of Luminophores For Aggregation Induced Electrogenerated Chemiluminescence, Jesy Alka Motchaalangaram

Dissertations

Most conventional luminophores produce intense emissions in solutions but suffer from weak emissions or quenching when aggregated in poor solvents due to intermolecular interactions, such as π-π stacking. This phenomenon is known as aggregation caused by quenching (ACQ), limits their applications in their solid state. In contrast, aggregation induced emission (AIE) is a phenomenon in which luminophores are weak- or non-emissive in solution but emit intensively in their aggregated or solid states. AIE has enabled significant advancements in various real-world applications and has inspired new areas of research. The combination of AIE with electrogenerated chemiluminescence (ECL) has resulted in a …
