Mining Public Opinion On Covid-19 Vaccines Using Unstructured Social Media Data, Chad Aaron Melton

Doctoral Dissertations

The emergence of the novel coronavirus (COVID-19), and the necessary separation of populations led to an unprecedented number of new social media users seeking information related to the pandemic. Nowadays, with an estimated 4.5 billion users worldwide, social media data offer an opportunity for near real-time analysis of large bodies of text related to disease outbreaks and vaccination. This study investigated and compared public discourse related to COVID-19 vaccines expressed on two popular social media platforms, Reddit and Twitter. Approximately 9.5 million Tweets and 70 thousand Reddit comments were analyzed from dates January 1, 2020, to March 1, 2022, and …

Emerging Trends In Bus Ridership In The United States, Abubakr Ziedan

Doctoral Dissertations

Public transit ridership in the United States was declining even before the COVID-19 pandemic. Many different factors affect transit ridership levels, and the recent declines in ridership across the country make it critical to assess which factors are causing declines and which may help to increase ridership. Therefore, this dissertation seeks to quantify the impact of three emerging factors on bus ridership: shared electric scooters (e-scooters), new fare payment technologies and policies, and the COVID-19 pandemic.

This dissertation analyzed the impacts of shared e-scooters on bus ridership. This was investigated at the route level in Louisville, KY, and Nashville, TN, …

Kitchen Invasion: Restaurants’ Business Model Innovations During The Covid-19 Crisis, Jaewoo Jung

Doctoral Dissertations

My dissertation explores how and why firms facing the same exogenous threats react differently, leading to different business model innovation (BMI) processes. I examine BMI in a context that has been hard-hit by COVID-19 pandemic restrictions—the restaurant industry. Employing a mixed-method research design, I conducted a longitudinal, inductive comparative case study of 17 restaurateurs in the same geographic region to explore how they have responded to the pandemic and how their BMI unfolded over time. To generalize my understanding of these processes, I then analyzed large-scale media data about the restaurant industry using topic modeling. In this quantitative analysis, I …

Relocating Community To The Virtual: Sound Knowledge, Affective Listening, And The (Dis)Embodying Of Sound And Space, Zachery D. Coffey

Masters Theses

Music within Protestant church communities frequently reduces the distinction between performers and audience, emphasizing the collective, participatory role of all congregation members, in manners of music making similar to those discussed by Thomas Turino. This dynamic helps establish individual and communal identities. With the onset of the COVID-19 pandemic, church communities saw changes in their services, music, and ways of life. Meeting in a physical building proved impossible due to the dangers of COVID-19 and many churches mitigated these dangers by streaming, recording, and posting services online. Between 2020 and 2022, I observed and participated in changes to technological production …

Design And Development Of The Urban Population Health Observatory To Improve Disease Surveillance And Response, Whitney Brakefield

Doctoral Dissertations

Chronic and infectious diseases have a profound impact on the quality and length of life of populations that suffer from these conditions. Scientists, physicians, and health officials are seeking innovative approaches to decrease the morbidity and mortality of deadly diseases. Incorporating artificial intelligence and data science techniques across the health science domain could improve disease surveillance, intervention planning, and policymaking. In this dissertation, we describe the design and development of the Urban Population Health Observatory (UPHO), an explainable knowledge-based multimodal big data analytics platform. A common challenge for conducting multimodal big data analytics is integrating multidimensional heterogeneous data sources, which …

Justice Involvement During Covid-19 And The Possibility Of Transitional Justice, Rachel A. Ponder

Doctoral Dissertations

The COVID-19 pandemic introduced numerous unprecedented political, social, and economic challenges that resulted in unprecedented responses by policy makers. As result, existing inequalities and injustices rooted in a dense history of structural and institutional violence were uncovered and exacerbated. As of June 2021, at least 398,627 people in prison tested positive for COVID-19 and at least 2,715 had died (The Marshall Project 2021). In the United States, the inmate population is disproportionately made up of poor, people of color. This is a pattern that is rooted in the country’s long history of racism and white supremacy. This cycle continues as …
