The Consequences of Early Life Stage Thyroid Suppression on Immune Function in the Fathead Minnow (Pimephales promelas)

Description: Current evidence suggests that thyroid hormones (THs) may impact development of the immune system. However, studies that explore the role of THs in immune development are limited, and the mechanisms leading to alterations in immune function are poorly understood. It is important to elucidate the role of THs in immune development given that many environmental contaminants have been shown to disrupt TH homeostasis and may also have negative impacts on the immune system. As such, the main goal of … more

Perception of Falls and Confidence in Self-Management of Falls among Older Adults

Description: Mobility safety, especially fall prevention, plays a significant role in successful aging for older adults. Fall preventive programs aim to reduce risks for mortality from fall-related injuries among older adults. However, the covariation between personal perceptions of falls and factors and confidence of self-management in falls (CSMoF) is still under-studied despite its importance to fall prevention. Using the International Classification of Functioning, Disability, and Health (ICF) model, th… more

Interlocal Competition and Local Fiscal Health

Description: A sizeable literature documents patterns of competition between local governments in metropolitan regions, while also exploring variation in such local government financial attributes as efficiency, budget size, fiscal disparity, and service equity, which are frequently bound together under the concept of fiscal health. However, the concept of fiscal health is broader and more sophisticated than any one fiscal measure, and empirical studies tend to focus only on multi-purpose governments. This … more

Privacy Preserving Machine Learning as a Service

Description: Machine learning algorithms based on neural networks have achieved remarkable results and are being extensively used in different domains. However, the machine learning algorithms requires access to raw data which is often privacy sensitive. To address this issue, we develop new techniques to provide solutions for running deep neural networks over encrypted data. In this paper, we develop new techniques to adopt deep neural networks within the practical limitation of current homomorphic encrypt… more

A Survey of 21st Century Gay-Themed American Art Songs for Baritone

Description: The majority of repertoire catalogs for singers, printed and digital, often list works by voice type, language, and/or genre. The 21st century has seen an emergence of online classical music catalogs where the user can seek repertoire by searching composers from underrepresented communities (i.e., women, Black, LGBTQ, Latinx). What does not currently exist is a resource that catalogs songs for solo voice dealing specifically with gay subject matter. This dissertation surveys seventeen 21st cent… more

Beyond Fourths and Pentatonics: A Critical Analysis of Selected Recordings of McCoy Tyner from 1962 to 1963

Description: In this paper, I explore the early musical language of McCoy Tyner. Today, Tyner is recognized mostly for his use of quartal harmony and pentatonic scales despite having made recordings in his early career that reflect a more mainstream approach. In an effort to expand how Tyner is represented, I argue that Tyner's early style was characterized by a graceful balance of tradition and innovation, a masterful blend of bebop syntax with pentatonic melodies and quartal harmonies. The recordings that… more

Institutionalizing Atrocity: An Analysis of Civil War Legacy, Post-Conflict Governance, and State Behavior

Description: This dissertation examines the behavior of post-civil war governments and explores how the aftermath of civil war not only influences state behavior but how the previous conflict becomes institutionalized through a state's governance decisions. While post-civil war states will each have different governance needs as they endure the post-conflict environment, this dissertation contends that the governance decisions a state chooses are key to understanding, and potentially predicting, future gove… more

Key Factors in Developing a Successful Bond Referendum in Texas School Districts

Description: In May of 2002, Wichita Falls ISD, a district in Texas with a stagnate enrollment of 14,000 students for multiple years, asked for the community to support a $120 million bond to help cover the cost of four new elementary campuses and to maintain and upgrade aging facilities. The bond failed. Additionally, a 2004 bond failed again. Finally, in 2006, the district is finally able to pass a $60 million bond and only includes two new elementary campuses and no funding to address the aging facilitie… more
