Framing The Problem To Meet The Policy Solution: An Embedded Mixed Methods Case Study Of The 2017 Michigan Opioid Laws, Leandra Hawkins Burke

Dissertations

The opioid crisis presents a wicked problem for public administration. Hundreds of thousands of people have died from opioid overdoses in the United States, and countless others have experienced severe opioid-related physical, psychological, and socioeconomic harms. Countering the opioid crisis has been difficult due to interdependencies across different drugs and multiple pathways for abuse and dependence. Many scholars, health providers, and politicians have called for a broad public health approach to combat the opioid crisis, but the full expanse of what that would entail has not yet been realized. What has been demonstrated is that interactions targeting a single aspect …

The Impact Of Feedback Timing On Work Performance When There Is A Long Duration Between Sessions, Priyanka B. Dave

Dissertations

Performance feedback is a powerful tool central to many functions at work, as it guides, motivates, and rewards employees’ behaviors. To better understand the function of feedback, previous research has examined the impact of feedback’s timing (proximal to the previous per-formance versus proximal to the next performance) on the effectiveness of feedback. However, the findings have been mixed across studies. Studies with less than 1-day between session dura-tions tend to find no difference between after-session versus before-session feedback. However, investigations with multiple-day between session durations tend to find improved performance with before-session feedback. This study used a counterbalanced across-subject design …

Multiple Monochromatic Subgraphs In Edge-Colored Graphs, Emma Felicity Jent

Dissertations

Ramsey theory, though a relatively young branch of mathematics, has captivated the attention of graph theorists, combinatorialists, and theoretical computer scientists alike through its raw beauty, versatility, and powerful applications. Before it emerged as a branch of mathematics, the central idea of Ramsey theory appeared in the form of three lemmas in three separate papers by three different mathematicians working on three distinct areas of research. The first such lemma was published by David Hilbert in 1892, followed by the second lemma published by Issai Schur in 1916. However, Frank Ramsey’s renowned lemma, published in 1930, compelled mathematicians to establish …

"It Can Be Hard To Stand Up Straight In A Crooked Room:" Examining The Mediating Effects Of Black Women's Gendered Racial Identity On The Relationship Between The Strong Black Woman/Superwoman Schema And Collective Coping, Devin Willis

Dissertations

Prior research on the Strong Black Woman (SBW)/Superwoman (SW) schema has produced mixed findings. Both positive and negative outcomes of Black women’s internalization of this schema have been identified. These mixed findings may be linked to the measurement of the SBW/SW schema and the relationship with other culturally relevant variables. There have been significant positive relationships identified between Black women’s gendered racial identity (GRID) and the internalization of gendered racial stereotypes (i.e., the SBW/SW). Methods for coping with stereotypes have also been identified as influential when considering Black women’s coping behaviors.

The purpose of this study is to examine the …

Mechanistic And Evolutionary Insights Into A Group Of Nicotine And Hydroxynicotine Degrading Flavoenzymes, Zhiyao Zhang

Dissertations

Flavoprotein amine oxidases (FAOs) are key enzymes in various kinds of metabolic pathways, mediating redox reactions via flavin cofactors. While most FAOs function as oxidases that readily reduce oxygen to hydrogen peroxide, a few outliers of the FAO family act as dehydrogenases that suppress the reaction with oxygen. The molecular basis for this divergence in function remains poorly understood.

The work presented in this study investigates the fundamental mechanisms of how flavincontaining enzymes activate or suppress their reaction with different electron acceptors to achieve high turnover rates. The overall body of work is divided into three different sections that (1) …

Mathematics, Physics, and Computer Science Faculty Articles and Research

This study presents a GIS-based multi-criteria decision-making framework to assess climate-induced migration risk along the West African coast. We developed a comprehensive risk index that integrates environmental hazards such as flood frequency and socio-economic vulnerability indicators, including poverty levels, population density, and adaptive capacity. By utilizing datasets such as the Geocoded Disasters (GDIS) dataset, Social Vulnerability Index (SVI), Poverty and Adaptive Capacity Index (PACI), and the Population Exposure Index (PEI), the study identifies regions most susceptible to displacement. Results reveal that areas like Benin’s Abomey-Calavi, Cotonou, and Akpo-Misserete are especially vulnerable due to high disaster frequency, substantial population exposure, and …

Dissipation Physics And Absorption Features In Black Hole X-Ray Binaries, Theodore Dezen Phd, Benjamin R. Cavallari

McNair Summer Research Program

As matter falls closer toward the center of the accretion disk it loses gravitational potential energy, part of which becomes radiation primarily in X-ray wavelengths. Accretion disk models often invoked to fit observed spectra predict relativistically smeared absorption features that are not present in data from black hole X-ray systems such as GX 339-4 and LMC-X3. Informed by recent local and global simulations, we conduct new disk structure and radiative transfer calculations with increased dissipation rates of gravitational potential energy into thermal energy in disk upper layers. We find a noticeable reduction of the absorption features compared to older models …

Development And Validation Of A Baseline Clinical Tool For Primary Care Providers To Address Nicotine Delivery System Usage In Adolescents, Monica M. Janssen

Doctoral Scholarly Projects & Capstones

Family practice providers are a pillar of the health care system as demonstrated through helping patients of all ages achieve health. Adolescents are a unique patient population in an age where they are moving toward adulthood, out of childhood, and vulnerable to influence. Providers could help adolescents shape their future in health through prevention. Preventative care including evidence-based evaluations and treatments could provide adolescents with a strong foundation in healthy adulthood. Adolescent electronic nicotine delivery system (ENDS) use is a public health issue that increases the risk of nicotine addiction and long-term health consequences.

The Market For Local Beef And Local Beef Processing Investment In Arkansas., Rebekah O'Neal

Graduate Theses and Dissertations

The COVID-19 pandemic exposed vulnerabilities in the U.S. food supply chain, particularly in the beef sector, where processing bottlenecks and labor shortages disrupted meat production and the market. In response, several policies were implemented to strengthen food system resilience, and significant funding was allocated to expand independent meat processing capacity nationwide. However, the long-term viability of expanding regional processing capacity remains uncertain, notably in Arkansas, a net exporter of live cattle. This study evaluates whether consumer demand supports the expansion of local beef processing in Arkansas. Using a dichotomous choice survey, we estimate market shares for beef labeled “Arkansas Grown” …

Connecting For Success: Evaluating The Frequency Of Check & Connect Meetings On Student Behavior, Kaylee S. Mckinney

Master's Theses

Dropout prevention efforts commonly address risk factors including chronic absenteeism, which continues to be a nationwide concern. Check & Connect is a student engagement intervention that aims to improve graduation rates and mitigate several risk factors of dropout. Previous research has failed to address if the frequency of Check & Connect meetings results in varied effectiveness of the intervention. The current study aims to evaluate the effects of modified frequency of Check & Connect meetings on academic engagement, term grade average, absences, and office discipline referrals through the use of a multiple baseline across participants design. Results revealed that students …

High-Resolution Event Stratigraphy Of Ostracods In The Ozan Formation Of Texas And Arkansas, Denali L. John

Master's Theses

This study focuses on the high-resolution event stratigraphic framework of the lower Campanian Ozan Formation in Northeast (NE) Texas and Southwest AR which is richly fossiliferous in ostracods. Little research has been published on the Ozan Formation and even less dealing with Ozan ostracods. Additionally, correlation of Upper Cretaceous units between Texas and AR is controversial due to the general lack of good exposures in both regions and extensive faulting in Northeast Texas despite similar depositional environment across the region. This study calibrates the ranges of ostracods and creates an event stratigraphic composite that is orders of magnitude higher in …

Social Sprouts: A Play-Based Packaged Intervention - Improving Peer Interactions In Early Childhood Classrooms With A Novel Group Contingency, Brittany D. Garza

Master's Theses

Teaching prosocial skills such as positive peer interactions in early childhood settings not only promotes behavioral health but reliably predicts future learning outcomes. The literature suggests that decreasing levels of challenging behavior may improve peer interactions, and a feasible class-wide strategy that can address this combination of needs effectively is a group contingency. The current study investigated the effect of a novel group contingency, Social Sprouts, on both positive peer interactions and disruptive behavior. This study utilized a nonconcurrent multiple baseline design in three Head Start classrooms to evaluate the effect of this packaged intervention delivered just before and during …

Master's Theses

This study investigates the historical presence and ecological significance of Arundinaria gigantea (giant cane) in 1810, Wayne County, Mississippi, using original survey documents. These records provide rare quantitative insights into the distribution of cane brakes, revealing that A. gigantea possibly represented up to 44% of the surveyed landscape, likely second only to Pinus palustris (longleaf pine).

This research involved digitizing historical surveyors' notes, transcribing them into a structured format, and extracting spatial data for GIS analysis. The methodology developed for this research can be used to ensure the preservation and usability of these historical documents for future research. …

Using Inquiry Classroom Experiences To Correct Student Misconceptions In Elementary Science: An Action Research Study, Hope A. Ellison

Master's Theses

Misconceptions in elementary science education can significantly hinder students' ability to construct accurate and lasting conceptual understandings. Grounded in the constructivist learning theory, this quasi-experimental study investigates how inquiry-based instruction influences the identification and correction of third-grade students’ misconceptions in science, specifically in the domains of energy, force, and matter. Using a pre- and post-test design, along with data derived from daily teacher field notes, the research was conducted with a sample of fifteen third-grade students at a public elementary school in Mississippi. The results, discussed in the methods section, revealed a statistically significant improvement in students’ conceptual understanding following …

Trust Across Difference In Radical Social Movement Organizations: The Case Of The Student Nonviolent Coordinating Committee, Kerstin Miller

Master's Theses

Social movement literature does not properly address trust between activists as a foundation of social movement organizations. This thesis aims to fill that gap by examining how trust within the Student Nonviolent Coordinating Committee, a radical civil rights organization in the sixties, was built and broken over the course of the decade. I drew on first-hand accounts written by SNCC activists to find patterns in how they thought about trust building and trust breaking in their own organization. I found that trust was built primarily through sustained interaction between activists, and that trust in the organization led to activists being …

Do Finances Determine Our Fate?: Understanding The Relationships Between Socioeconomic Status, Inflammation, And Cancer Recurrence Risk, Faith Wilbourne

Master's Theses

Individuals of a low socioeconomic status (SES) are more likely to experience a cancer recurrence relative to individuals with a higher SES. This may be partially explained by the stressors of living with a low SES. These stressors can increase inflammatory markers known to elevate the risk of cancer development. Health-promoting behaviors such as exercise, adequate sleep, and a healthy diet can reduce systemic inflammation. Health behaviors may therefore moderate any potential relationship between SES and cancer recurrence risk. This study explored associations between SES (income, educational attainment) and inflammatory markers related to cancer recurrence while seeking to determine if …

Reflecting On Racial Microaggressions: The Impact On Food Consumption In Minority Women, Khadiza Akter

Master's Theses

U.S. laws, policies, and practices have been implemented to reduce forms of overt racism and discrimination. These structural barriers have been effective (e.g., Dovido & Gaertner, 2000; McConahay, 1986; Sue & Sue, 2007). Covert forms of racism, however, including racial microaggressions, are more difficult to address using structural changes and, therefore, continue to thrive (Omi & Winant 1994; Sue et al., 2007). Racist attitudes and discriminatory behaviors are sources of anxiety and stress (Kogan et al., 2014; Pascoe & Richman, 2009) with long-term anxiety and stress leading to elevated risks for mental and …

Exploring Fisheries Species Distribution Shifts In Response To Freshwater Inflow Through The Bonnet Carré Spillway Using Species Distribution Models, David T. May

Master's Theses

The Bonnet Carre Spillway (BCS) is a flood control structure on the Mississippi River (MR) ~52 km upstream of New Orleans. The BCS protects downstream communities from MR flooding by diverting floodwaters into Lake Pontchartrain when the MR exceeds 5.18m flood stage. Diverted waters flow east into the Mississippi Sound (MSS), introducing turbid, nutrient rich freshwater to the estuary before draining into the Gulf of Mexico. BCS openings have become much more frequent in the last decade, though little work has been done to explore the impact of the BCS on nektonic fisheries species. Here, a series of seasonal Maximum …

Assessment Of A Muscadine Grape (Vitis Rotundifolia) Mapping Population For Tolerance To Pierce’S Disease Pathogen Xylella Fastidiosa And Resistance To Black Rot Disease Pathogen Guignardia Bidwellii, Anushka Tennakoon

Master's Theses

Pierce’s disease (PD) and black rot disease cause severe economic losses for grape production under humid and warm conditions. Identifying resistance genes is crucial for controlling these disease by developing resistant cultivars. Muscadine grape (Vitis rotundifolia) cultivar ‘Pam’ has been identified to possess a high level of resistance to diseases. To elucidate the genetic basis of the resistance to the causal pathogens Xylella fastidiosa and Guignardia bidwellii in this cultivar, parents and 141 F1 individuals developed from open pollinated ‘Pam’ were evaluated for two seasons under natural disease pressure. The mapping population was genotyped using genotyping-by-sequencing (GBS) and …

Female Preference And Prezygotic Isolation In The Fundulus Notatus Species Complex, Emilee K. Holderness

Master's Theses

Understanding how reproductive isolation arises between closely related species is central to evolutionary research. Hybridization is widespread across taxa and shaped by interactions among environmental factors, evolutionary history, genetic compatibility, and behavior. These forces often operate nonlinearly across space and time, yet mate choice is frequently assessed under artificial conditions that may not reflect natural behavior. To address this limitation, female mate preference was investigated within the Fundulus notatus species complex, where F. notatus and F. olivaceus hybridize at varying rates across replicate contact zones. Using a free-choice design, behavioral trials were conducted with individuals from populations characterized by high …

Inside The Walls Of The Asylum: Exploring The Lives Of Individuals In The Mississippi State Asylum (1855-1935), Savannah V. Logan

Master's Theses

The Mississippi State Asylum (MSA), established in 1855, was the first such institution in but has been largely forgotten about since its closure in 1935. The cemetery associated with the facility, which is located on the University of Mississippi Medical Center campus, was recently rediscovered with new construction. As part of the Asylum Hill project, the remains of seven of the 7000 burials along with their mortuary artifacts were analyzed and allowed these forgotten individuals to once again regain their voice and tell a portion of their life story through osteobiographies.

The sample, dating to 1855-1899, included five males and …

Background: The SPAN (Stroke Preclinical Assessment Network) is a confirmatory multicenter trial network to test cerebroprotective interventions in experimental acute stroke. In a first-of-its-kind trial, SPAN tested 6 interventions in a rodent model of transient focal ischemic stroke. Here, we report the efficacy of fasudil, an isoform-nonselective rho-associated kinase inhibitor, on primary and secondary outcomes in the SPAN trial.

Methods: Fasudil was administered at 10 mg/kg intraperitoneally every 12 hours for 6 doses starting 5 minutes before reperfusion in a 60-minute endovascular filament middle cerebral artery occlusion model. The active treatment arm (n=345) was compared with the pooled intraperitoneal and …

Family-Level Factors That Influence Physical Activity Among Hispanic Adolescents At Risk For Type 2 Diabetes, Sandra Mihail, Ayleen A Hernandez, Erica G Soltero

Children’s Nutrition Research Center Staff Publications

Objective: Family-based health promotion and disease prevention strategies are recommended as best practice; however, there is limited knowledge regarding the family-level factors that influence modifiable behavior risk factors like physical activity (PA) among Latinx adolescents. This study addressed this knowledge gap by using qualitative methods to identify perceptions of family-level factors that influence PA among Hispanic youth.

Methods: We conducted semistructured, open-ended interviews with 20 Latinx adolescents (14-16 years) with obesity (body mass index ≥95th percentile) to identify their perceptions of how family influences PA. Content analysis was used to identify emergent themes, which were then compared across demographic factors, …

Analysis Of An Ethanol Sensitive Bmp-Nkx2.3-Fgf Signaling Pathway In Pouch Morphogenesis., Hieu Dai Le Vo

Electronic Theses and Dissertations

Craniofacial malformations lie at the heart of Fetal Alcohol Spectrum Disorders (FASD). While there is growing evidence for a genetic component to FASD, little is known of the cellular mechanisms underlying these ethanol-sensitive loci in facial development. Bone Morphogenetic Protein (Bmp) signaling pathway dependent pouch formation is a key mechanism in facial development. We have previously shown that multiple Bmp mutants are sensitized to ethanol-induced facial defects. However, ethanol does not directly impact Bmp signaling. This suggests that downstream effectors, like nkx2.3 and Fibroblast Growth Factor (Fgf) signaling, may mediate the impact of ethanol on Bmp mutants. Here, I …

Understanding The Potential Impact Of Ostracism On Lgbtq Health Disparities, Ellen D.B. Riggle

Political Science Faculty Publications

Research finds harmful impacts of ostracism on the health and well-being of the ostracized individual (as well as the ostracizer and members of the community). While often conceptualized as social (interpersonal), ostracism may originate at multiple levels of the socio-ecological system, including forms of political and institutional ostracism. The ostracism of LGBTQ people originates in cultural stigma and is reproduced and reinforced at all levels, from discriminatory laws and institutional policies (e.g., workplace, educational), to the actions of community or family members, to interactions with strangers. Ostracism, acute and chronic, creates increased risk for psychological and physical harm to LGBTQ …
