Remedies For Non-Disclosure In Asset Sales: Voidance Vs. Damages, Albert H. Choi, Kathryn E. Spier

Law & Economics Working Papers

This paper analyzes the problems of non-disclosure in the context of an asset sale between a buyer and a seller. The seller can have important information about the asset and can opportunistically decide not to disclose that information to the buyer, and the buyer may sue the seller ex post for remedy. The buyer and the court have a choice over different types of remedy. The paper considers three different remedy regimes: (1) no liability; (2) voidance; and (3) damages. Under voidance, the buyer can rescind the transaction (return the asset and get the price back), while with damages, the …

Uncovering Environmental Justice Disparities: Tree Canopy Inequality In Low-Income Marginalized Communities, Emmanuel Wallace

Tennessee State University Alumni Theses and Dissertations

Tree canopy inequality in low-income marginalized communities is a direct result of decades of environmental injustice within urban communities in the United States, specifically the Home Owner’s Loan Corporation. This phenomenon underscores the disproportionate distribution of tree cover, green spaces, and their myriad benefits in neighborhoods marked by poverty and social vulnerability. Rooted in a history of discriminatory urban planning practices and systemic disparities, tree canopy inequality has profound consequences on residents' health and well-being. It leads to urban heat island effects, reduced air quality, and additional socio-economic disparities. On average, urban communities of color have 33% less tree canopy …

Dietary Modulation Of Obesity-Specific Gut Microbial Signatures And Their Functional Roles, Anjula Swathi Sagam

Tennessee State University Alumni Theses and Dissertations

Obesity remains a major global health concern, contributing significantly to chronic diseases. While diet is a well-known driver of obesity, emerging evidence suggests the key role of gut microbiota in mediating diet-related metabolic outcomes. Numerous epidemiological and microbiome studies suggested diet-microbiome-obesity associations. However, consistent microbial markers and mechanistic insights remain limited. To address this gap, this study aimed to identify consistent microbial species associated with obesity and investigate how diet influences their growth and function. A review of over 200 publicly available 16S rRNA and shotgun metagenomic studies revealed consistent microbial patterns in obesity, including members of Firmicutes and Bacteroidetes. …

Development Of The Negative Attitudes Toward Nonbinary Individuals Scale, Jenna Sue Lehmann

Tennessee State University Alumni Theses and Dissertations

Research within the field of psychology examining the experiences of transgender individuals and prejudice toward transgender individuals has increased in recent history alongside the conscious awareness of transgender individuals within the United States. The research that has been conducted has primarily focused on transgender individuals broadly as a group on binary transgender individuals. As, such measures of prejudice toward these groups have been developed and validated. Although the study of nonbinary experiences and prejudice is developing, there has been no extant measure of prejudice toward nonbinary individuals specifically. A measure of prejudice toward this group is needed to (1) examine …

Exploring The Cooling Effects Of Urban Forests In Summer, Xiaoyue Li

Tennessee State University Alumni Theses and Dissertations

As a nature-based solution to combat urban heat islands, urban forests can provide cooling and other co-benefits. However, little is known about the cooling benefits of urban forests in parking lots and under different land covers, especially with field observations. To address this gap, we measured air temperature (AT) and relative humidity (RH) and calculated heat index (HI) in three urban settings in Nashville, TN, in summer 2024. The research sites included: 1) Two different parking lots: parking lots with and without trees; 2) Three different distances from trees within the parking lot with trees: under trees, near trees, and …

Dynamics And Controls Of Greenhouse Gas Emissions In Bioenergy Croplands, Lovish Kasrija

Tennessee State University Alumni Theses and Dissertations

Agriculture contributes considerably to global greenhouse gas (GHG) emissions, requiring sustainable methods for tackling climate change. This thesis includes two mega-analyses and one field experiment to investigate the impact of conservation tillage and soil amendments on crop productivity and greenhouse gas emissions. The first mega-analysis combined data from 30 meta-analyses to assess the impact of no-tillage (NT), reduced-tillage (RT), and combination NT+RT on crop yields and soil GHG emissions. NT decreased yields by 3.3% and increased N₂O emissions by 8.7%, but RT and NT+RT had no effect. The second mega-analysis found that both NT and RT considerably increased soil organic …

Effects Of Straw Return On Crop Yield, Soil Organic Carbon And Greenhouse Gas Emissions, Maazeera Fatima

Tennessee State University Alumni Theses and Dissertations

Global crop residue production was substantial, at approximately 3758 × 106 mg annually. The practice of straw return, was found to enhance soil organic matter content, increase crop yield, and mitigate soil greenhouse gas emissions. However, individual studies showed inconsistent results. While meta-analyses synthesized multiple individual studies and provided overall effects of straw return, but their conclusions were varied. We evaluated meta-analyses on the effects of straw return on crop yield, soil organic carbon, and greenhouse gas emissions and proposed a grand mean response ratio to estimate an overall effect and the impacts of different properties. The result showed that …

Gentrification And Voter Turnout In Urban School Board Elections, Erika Leicht

Tennessee State University Alumni Theses and Dissertations

Gentrification is a process in which low-income urban neighborhoods experience reinvestment and an influx of higher socioeconomic status (SES) residents. There is a growing literature on the impacts of gentrification on public schools, including effects on enrollment, student achievement, and parent involvement. This study examined whether gentrification is related to voter turnout in school board elections in urban local education agencies (LEAs) in Texas. It also examined whether the relationship between gentrification and voter turnout varies depending on the availability of school choice options and the racial/ethnic differences between public school students and neighborhood populations. Using a fractional logistic regression …

Influence Of Parental Approval And Disapproval On Interracial Relationship Outcomes, Stefanie Boakye

Tennessee State University Alumni Theses and Dissertations

Interracial couples may encounter unique challenges in their relationships due to negative perceptions such as racial prejudice, discrimination, disapproval, cultural stereotypes, and opposition from society and family. These challenges can be especially difficult when the disapproval comes from their parents. This study explored how perceived parental approval influences interracial romantic relationship outcomes, specifically relationship satisfaction, commitment, and closeness. Data were collected from individuals in interracial relationships (N ≈ 80) using the Relationship Assessment Scale (RAS), the Investment Model Scale (IMS), the Relationship Closeness Inventory (RCI), and the Parent-Adult Child Relationship Questionnaire (PACQ). A multivariate analysis of variance (MANOVA) was conducted …

A Case Study Of Public Policy, Neighbourhood Change, And Transit Equity Outcomes, Stacy-Ann Baker

Tennessee State University Alumni Theses and Dissertations

Despite intentions or understatement, public policy has influenced neighbourhood change, such as gentrification. However, its impact tends to be muted, ignored, or underappreciated. Transit equity policy and research have also lacked a robust social justice framework that considers spatial justice. Additionally, there have been several knowledge gaps, limitations, and mixed results regarding impacts, notably concerning buses, bus rapid transit (BRT), accessibility, and communities of concern. Unlike other studies, this dissertation proposal employs the social-ecological system framework (SESF), the public transportation sustainability list (PTSIL), and sustainability impact assessment (SIA) guidance from the Organization for Economic Co-operation and Development (OECD) in a …

Distribution And Occurrence Of Cyanohabs, Nutrients, And Water-Quality Data In The Tennessee State University Wetland, Kristi Hill

Tennessee State University Alumni Theses and Dissertations

Toxic algal blooms are an expanding issue for aquatic ecosystems because they are hazardous to human and environmental health. Algal blooms naturally occur from the combination of warm temperatures, sunlight, and abundant nutrients in water, but what triggers them to become harmful algal blooms (HABs) and begin synthesizing toxin is not well understood, and their threat to freshwater sources was not heavily researched until recently. Microcystin (MC), a freshwater algal toxin, is a HABs toxin which targets the liver and causes sickness and death in humans and animals (pets, livestock, and wildlife). Urban freshwater wetlands are among the most HAB …

The Impact Of Supervisor Cultural Humility On The Supervisory Working Alliance Among International Trainees, Fanchen Gao

Tennessee State University Alumni Theses and Dissertations

Supervisor cultural humility has been theorized to contribute to stronger supervisory working alliances (SWA), yet limited research has examined its role within multicultural contexts involving international trainees. Guided by the Multicultural Orientation framework, this study explored whether supervisors’ cultural humility predicted the quality of the supervisory working alliance, whether the relationship differed based on participant role (supervisor or trainee), and whether international trainees’ cultural backgrounds influenced their perceptions of the SWA. The sample included 72 participants from counseling and psychology training programs in the United States, consisting of international trainees and clinical supervisors. Participants completed an online survey assessing cultural …

Mindfulness And Student Achievement In Urban Middle After-School Programs, La Shell Bonds

Tennessee State University Alumni Theses and Dissertations

This dissertation explores the influence of mindfulness-based interventions on academic achievement, disciplinary outcomes, and social-emotional learning (SEL) competencies among urban middle school students participating in after-school programs. Grounded in Vygotsky’s sociocultural theory, self-regulatory frameworks, and Dweck’s growth mindset, the study employs a quasi-experimental design with 36 participants randomly assigned to either a mindfulness intervention group or a control group that receives the standard SEL curriculum. Over two weeks, the experimental group engaged in structured mindfulness activities—including breath awareness, body scans, and peer-led circles,—while quantitative data were collected on standardized test scores (Math and English Language Arts), suspension rates, and SEL …

In a randomized, dose-response trial, we used molecular and phenomic profiling to compare responses with traditional moder ate-intensity endurance and resistance training (TRAD) versus high-intensity tactical training (HITT) that encompassed explosive whole-body interval training and high-intensity resistance training. Ninety-four participants (18–27 yr) completed 12 wk of TRAD or HITT followed by 4 wk of detraining. Although similar performance and body composition improvements were observed in response to HITT and TRAD, some dose-dependent differences were observed for: 1) ex vivo muscle tissue changes in myofiber size, capillarization, satellite cell frequency, and mitochondrial function and 2) differential gene expression (DGE) of muscle …

Satellite Cells Choreograph An Immune Cell-Fibrogenic Cell Circuit During Mechanical Loading In Geriatric Skeletal Muscle, Nicholas T. Thomas, Camille R. Brightwell, Allison M. Owen, Alexander R. Keeble, Sabin Khadgi, Yuan Wen, Christopher S. Fry, Kevin A. Murach

Physiology Faculty Publications

Muscle stem cells, or satellite cells (SCs), decline in number throughout the lifespan and may become senescent in very old age. Whether and how remaining SCs contribute to muscle adaptation in the oldest-old is unclear. Using acute mechanical overload in geriatric SC replete and depleted mice (28-month-old) combined with single-cell RNA-sequencing, we show: (i) subsets of geriatric SCs display signs of senescence as well as normal fate progression during overload, (ii) SCs express markers that may contribute to the regulation of innervation, (iii) the presence of SCs during overload enhances global intercellular communication and increases mRNA levels of the cell …

Ibi-Dt: A Novel Approach Combining Individualized Bayesian Inference And Decision Tree For Identifying Cancer Drivers And Their Interactions, Md Asad Rahman, Gregory F. Cooper, Jinying Zhao, Xinghua Lu, Jinling Liu

Engineering Management and Systems Engineering Faculty Research & Creative Works

Cancer is mainly caused by a relatively small portion of somatic genome alterations (SGAs), called cancer drivers. Despite success in identifying a good number of cancer drivers, many more remain to be discovered to explain various cancers. Moreover, limited tools are available to identify potential interactions among cancer drivers for a better understanding of oncogenesis. To tackle these challenges, we have developed a novel approach called individualized Bayesian inference using a decision tree (IBI-DT). IBI-DT recognizes the genetic heterogeneity among cancer patients, where different individuals or patient subgroups of distinct genomic makeup may have different drivers. IBI-DT works by constructing …

The Role Of Implicit Bias In Police Citizen Interactions - A Historical Review And Policy Recommendations, Catherine Anne Liedman, Ziwei Qi

International Journal of Undergraduate Research and Creative Activities

Abstract

This paper examines the impact of implicit bias on police-citizen interactions, contributing to racial disparities in stops, arrests, and the use of force. While explicit racism has declined since the Civil Rights Era, unconscious stereotypes continue to influence law enforcement decisions. Research highlights that Black individuals experience higher rates of police encounters and fatal force compared to White individuals, a pattern not fully explained by crime rates but rather by systemic and historical biases within policing institutions. Efforts to address implicit bias, such as diversity training, have shown limited long-term effectiveness. Instead, meaningful reform requires structural changes, including improved …

As of 2024, approximately 36% of bridges across the United States require repair or replacement, with 7% classified as structurally deficient. The estimated cost to address these deficiencies exceeds $260 billion. In recent years, Ultra-High-Performance Concrete (UHPC) has emerged as a repair material for infrastructure preservation, drawing increased attention from transportation agencies and researchers worldwide. The Federal Highway Administration (FHWA) has notably advocated for UHPC’s adoption in bridge preservation initiatives, recognizing its exceptional mechanical properties and durability.

This report presents a comprehensive literature review on the application of UHPC as a repair and strengthening material for bridge compression members. While …

The Uk's Intended Move To Electric And Connected And Autonomous Vehicles: Are Infrastructural Barriers Preventing Successful Transition?, Katy Ferris, James Marson

Transportation Law Journal

The advent of Connected and Autonomous Vehicles (CAVs) is poised to transform global transportation systems, offering unparalleled opportunities to enhance safety, sustainability, and efficiency. Given that CAVs are most likely also to be electric vehicles (EVs), and in the UK, CAVs/EVs are a central element of government efforts to modernise mobility while achieving net-zero emissions by 2050, it would seem the UK is ready to embrace the transition to this new and disruptive form of transportation. However, while technological innovation has surged, critical questions remain about the readiness of physical, digital, and policy infrastructures to support the widespread adoption of …

From Displacement To Design: Reframing Work, Skills, And Education For The Ai-Transformed Economy A Review, James Hutson

Faculty Scholarship

Between 2023 and 2025, the U.S. labor market entered a period of accelerated restructuring driven by generative artificial intelligence (AI) and automation. Routine, entry-level cognitive roles—particularly in clerical, customer service, and junior technical positions—contracted sharply as intelligent systems assumed high-volume, rules-based tasks. While these displacements echo past automation cycles, the present transformation is distinct in its scope, affecting both knowledge work and creative functions, and in its speed, amplified by enterprise-scale adoption. Simultaneously, demand has surged for specialized AI-related positions, interdisciplinary roles blending domain expertise with AI fluency, and ―durable skills‖ that remain resistant to automation. Drawing on labor market …

Adversaguard: A Distributed Data-Poisoning Benchmark For Parallel Ai, Yulia Kumar, Solomon Thomas, Dejaun Gayle, J. Jenny Li, Dov Kruger

Center for Cybersecurity

As organizations scale model training across large clusters and clouds, data poisoning has emerged as a significant practical threat. Most existing research focuses on data poisoning in single-node environments. Far fewer studies have compared the effectiveness of attacks across parallel training strategies, where factors like gradient aggregation and distributed memory ceilings fundamentally alter attack detectability and its impacts. To address this gap, we introduce AdversaGuard, a reproducible benchmark and accompanying application designed specifically for distributed settings to protect AI training pipelines. This research makes the following key contributions: (1) A comprehensive Distributed Data Poisoning (DDP) benchmark spanning seven distributed systems …

Enhancing Non-Player Character Dialogue In Video Gages: An Evaluation Of Large Language Model-Generated Responses, Lam P. Quach

Master's Theses

As video games increasingly emphasize narrative depth and player immersion, the quality of Non-Player Character (NPC) dialogue has become crucial for creating engaging gaming experiences. This thesis investigates the potential of Large Language Models (LLMs) to generate high-quality NPC dialogue by comprehensively evaluating four state-of-the-art models: Gemma 3 27B, Mistral 7B, QWEN 2.5, and LLAMA 3.1. The study employs a mixed-methods approach, combining human evaluation (N=50 participants) with AI-based assessment across five key benchmarks: coherence, personality expression, engagement, style/tone appropriateness, and overall quality. Participants evaluated 32 dialogue samples (8 per model) generated for a fantasy game context featuring two distinct …

First-Time Mothers' Experiences Of Breastfeeding During The Early Postpartum Period In Nairobi, Kenya: A Qualitative Study, Viola Siongei, Rose Maina, Eunice Pallangyo

School of Nursing & Midwifery, East Africa

Background/Aims The rate of exclusive breastfeeding in the first 6 months is still low, despite global active promotion of the practice. The exclusive breastfeeding rate among first-time mothers is much lower than among multiparous women, which has been attributed to difficulties assuming the new role and a lack of breastfeeding skills. This study aimed to gain an in-depth understanding of first-time mothers' breastfeeding experiences and the factors that influence these experiences during the early postpartum period in Nairobi, Kenya.

Methods This qualitative explorative, descriptive study involved 17 purposively sampled first-time mothers at 4–6 weeks postpartum. In-depth, face-to-face semi-structured interviews were …
