Curation And Analysis Of Ai Ready Environmental Justice Datasets : A Proof-Of-Concept Study, Paridhi Parajuli
Theses
Equity and Environmental Justice (EEJ) advocates for unbiased distribution of environmental impacts across communities, regardless of social and economic characteristics. After extreme events like natural disasters, EEJ gains importance due to evident disparities in impact among communities. Addressing these injustices requires comprehensive datasets and analytical methods for quantification and resolution. While AI and advanced data analysis offer promising solutions, creating AI-ready EEJ datasets is challenging due to heterogeneity in the data surrounding EEJ. In this work, we focus on curating novel datasets for EEJ targeting a few recent extreme events - Maui Wildfire, Hurricane Harvey, and Hurricane Ida. We demonstrate …

The Effect Of Emotional Demeanor Of Adult Sexual Assault Victim Testimonies On Mock Jurors' Verdicts, Callie Ahearn
Theses
Experiencing a sexual assault and testifying in trial are both highly emotional events that can influence a witness to display strong negative emotions. The display of emotion is referred to as the emotional demeanor and the present study examined the impact of a victim’s emotional demeanor on jury decision-making. Results revealed a main effect of crying during the direct examination with more guilty verdicts and higher pro-victim ratings (believability, credibility, and trustworthiness). Female participants provided higher pro-victim judgments on believability than male participants. Verdict reasoning demonstrated that participants had an idea of what they expected a rape victim to look …

Hyperinsulinemic Lew.1wr1 Rats Develop Insulin Resistance And Nonalcoholic Steatohepatitis, Madushika M. Wimalarathne
Dissertations
The pathophysiological causes of nonalcoholic steatohepatitis (NASH) development are not fully understood but are often associated with hyperinsulinemia, insulin resistance and ectopic lipid accumulation. A subpopulation of type 1 diabetes patients develops the pathophysiological parameters to be termed “double diabetes,” which is associated with NASH. The objective of this work was to identify metabolic features of double diabetes and assess if LEW.1WR1 rats develop NASH. I assessed pathophysiologically relevant protein changes using proteomics and western blotting. I found that 17-week-old LEW.1WR1 rats showed protein changes related to non-alcoholic fatty liver disease, a precursor to NASH. We tested a second population …

The Effectiveness Of System-Wide Trust Repair Strategies, J. Andrew Atchley
The Effectiveness Of System-Wide Trust Repair Strategies, J. Andrew Atchley
Theses
This study considered whether contagion effects for trust extend to an interactive task that includes tasks that are visually incongruent and perform dissimilar task functions, and if trust repair strategies operate on a system-wide basis. Participants supervised three automated tasks over three blocks. The animal task decreased in reliability in block 2, and a trust repair strategy was issued prior to block 3. The findings indicated that there was a decrease in trust for the animal task only. The trust repair strategies were also ineffective for restoring trust. This study supported the idea that contagion effects do not extend to …

Algorithmic bias, also known as algorithmic discrimination or AI bias, is a pervasive phenomenon marked by the systematic and unjust treatment of specific demographic groups based on attributes like race, gender, age or other distinguishing characteristics. The widespread adoption of artificial intelligence (AI) and machine learning algorithms across various domains has amplified concerns surrounding algorithmic bias, which has the potential to perpetuate discrimination and deepen societal inequalities. This thesis embarks on a comprehensive exploration of algorithmic bias, delving into its multifaceted nature. It dissects various forms of bias, including selection bias, confirmation bias, and measurement bias, shedding light on the …
Differences In Effectiveness Of Intrinsic And Extrinsic Motivation-Based Incentives In Promoting Use, Acceptance, And Adoption Of Automated Systems, Hannah M. Barr
Theses
This study examines the effectiveness of incentive mechanisms manipulating extrinsic and intrinsic motivation. Specifically, these incentives are used to promote use, acceptance, and adoption of an automated system in a simulated hostage-rescuing task. More frequent use of the automated system indicates increased acceptance and adoption. Participants are measured for how frequently they use the system. Participants also responded to questionnaires measuring their motivation, acceptance, and adoption. Bayesian ANOVAs are used to find differences in use, acceptance, and adoption between incentive mechanisms. It was expected that incentive mechanisms affecting intrinsic motivation will outperform incentive mechanisms affecting extrinsic motivation in promoting system …
Feature Selection In High-Dimensional Space With Applications To Gene Expression Data, Nishan Pantha
Feature Selection In High-Dimensional Space With Applications To Gene Expression Data, Nishan Pantha
Theses
Recent years have seen rapid growth in high-dimensional datasets. Most existing machine learning (ML) algorithms fail in high-dimensional settings where many features could be redundant. A critical process of feature selection is thus applied in such a setting that helps in identifying the most relevant features while removing redundant ones. With the increase in high dimensionality, one is also faced with problems of efficiency and interpretation in performing such selection methods. Therefore, this thesis proposes a “novel” feature selection framework that uses an ensemble of interpretable ML algorithms to perform feature selection and the ranking of final features. Finally, this …
Connecting Bridges : A Critical Disability Reading Of A Silent Voice, Tyler Dickey
Connecting Bridges : A Critical Disability Reading Of A Silent Voice, Tyler Dickey
Theses
Disability scholars have read stories in the form of manga to see how their depictions of disabilities can be harmful or helpful to those possessing disabilities. Most manga examined in this way usually consists of a story where either only one character is present with a disability, or the story falls within the ‘supercrip’ narrative. Yoshitoki Ōima’s A Silent Voice differs from this trend as it displays multiple characters with different types of disabilities and falls into the slice-of-life genre. This thesis exists to do a critical disability reading of A Silent Voice as a piece of disability literature. I …
