Digital Marketplaces As Conditional Economic Infrastructure In Conflict-Affected Economies, Diana Umerova

Student Publications and Presentations

Armed conflict disrupts trade, logistics, and financial institutions, constraining firms’ ability to participate in domestic and international markets. While prior research documents macroeconomic losses and supply-chain shocks, there is limited explanatory analysis of how digital marketplaces operate as conditional economic infrastructure under active conflict. Using the Russia–Ukraine war as a contextual case, this thesis extends a qualitative, secondary-data analysis to explain how digital marketplaces function through the economic mechanisms of alternative market access, organizational reconfiguration, and digital payment facilitation, while acknowledging structural constraints, elevated transaction costs, and platform governance risks. Building on existing research, the study argues that digital marketplaces …

The Opioid Crisis In The United States Vs. Portugal’S Public Health Approach, Ciara Dillon

Student Publications and Presentations

The opioid epidemic in the United States is a persistent public health issue exacerbated by increasingly dangerous and potent synthetic opioids. Although there are growing levels of access to naloxone and medication-assisted treatment (MAT) as well as growing numbers of overdose-related deaths, these data indicate that U.S. drug policy continues to be characterized by a primarily reactive and partially punitive framework. This study will compare the U.S. drug policy model to that of Portugal, which fully decriminalized all illicit drugs in 2001, shifting from a national drug policy based on punishment and repression to one focused on preventing the consumption …

Engineering Function In Lung Biology: Integrating Imaging, Regenerative Constructs, And Functional Biodesign, Rene A Girard, Jamie Tran, Yuqing Cai, Mary C Farach-Carson, Hadi T Nia, Allison M Greaney, Laura E Niklason, Killian Hurley, Elvin Blanco, Sinem Koc-Günel, Harry Karmouty-Quintana

Faculty, Staff and Student Publications

The lung is a uniquely demanding target for regeneration because function depends on the coordinated integration of cellular diversity, three-dimensional architecture, cyclic mechanical forces, vascular perfusion, immune surveillance, and extracellular matrix remodeling. While single-cell and spatial profiling, lineage tracing, and iPSC-derived models have transformed our understanding of lung cell states and developmental potential, these descriptive approaches have also highlighted a central bottleneck: the field still lacks broadly adopted platforms to test whether engineered tissues and regenerative interventions restore function under physiologic load. In this review, we focus on emerging technologies that enable functional biodesign in lung biology by coupling engineered …

College of Population Health Faculty Papers

BACKGROUND: Pakistan's persistently high maternal (178 per 100 000 livebirths) and neonatal (41 per 1000 livebirths) mortality ratios are compounded by lack of reliable data on the root causes and preventable risk factors, which hinders their effective use in improving care and progress toward safe, high-quality services. We sought to identify system delays impacting maternal and perinatal deaths using a facility-based death audit review system integrated with community engagement for implementing actionable solutions.

METHODS: We used a mixed methods, concurrent parallel study design at three secondary level healthcare facilities in District Matiari, Sindh, Pakistan. We reviewed 319 cases that included …

Elected Sheriffs’ Election Process And How It Affects Their Behavior, Brian James Ardoin

Walden Dissertations and Doctoral Studies

Scholars have widely examined how electoral pressures influence the behavior of judges and prosecutors; however, less attention has been given to how elections affect law enforcement leaders. This quantitative study examined whether sheriff election cycles in Louisiana were associated with changes in law enforcement behavior. Louisiana parish sheriffs occupy a unique role as both elected officials and chief law enforcement executives, which may create incentives that influence enforcement priorities. Using secondary arrest data from the Federal Bureau of Investigation Uniform Crime Reporting program, this study analyzed parish-level arrest patterns from 2009 through 2019 to determine whether deputies’ arrest behavior differed …

Exploring Marital Resilience Through The Lived Experiences And Perception Of Spousal Support During Events Of Shared Stressors, Prince-James Smith

Walden Dissertations and Doctoral Studies

Marital resilience during shared stressors remains insufficiently understood, particularly when both spouses are simultaneously affected by the same external stressor and must adapt together over time. The purpose of this qualitative phenomenological study was to explore marital resilience through the lived experiences and perceptions of spousal support during shared stressors among individuals who had been legally married for 10 years or more, with specific attention to how participants described the shift from solo coping to dyadic coping over time. Bowlby’s attachment theory provided the theoretical foundation, and Senge’s learning organization theory served as the conceptual framework. Participants included 18 legally …

Mergers and acquisitions (M&A) have been widely used as a growth strategy; however, many organizations fail to achieve their desired outcomes. This ongoing risk is a major concern for business leaders because ineffective post-merger personnel integration can disrupt workforce stability, reduce productivity, and hinder organizational performance. Grounded in transformational leadership theory, the purpose of this qualitative pragmatic inquiry project was to explore the strategies business leaders used to integrate personnel during post-merger transitions. Data were collected through semistructured interviews with eight business leaders from global corporations who had successfully executed mergers and acquisitions, along with a review of publicly available …

Contra Continuous And Irresolute Maps Via M-Open Sets In N-Cylindrical Neutrosophic Topological Spaces, S. Anandhi, R. Vijayalakshmi, Shantha K. Lakshmi

Neutrosophic Sets and Systems

This paper introduces and investigates the concept of n-cylindrical neutrosophic contra M-continuous mappings within the framework of n-cylindrical neutrosophic topological spaces. Motivated by recent advances in neutrosophic contra continuous functions, irresolute mappings, and n-cylindrical fuzzy neutrosophic topological structures, the study establishes several fundamental properties of n-cylindrical neutrosophic contra M-irresolute mappings. The proposed mappings are analyzed in relation to existing classes of neutrosophic contra continuous and contra irresolute functions, highlighting their structural properties and interrelationships. The obtained results extend and generalize earlier studies in neutrosophic topology, thereby contributing to the theoretical development of neutrosophic topological spaces. Furthermore, this work provides a …

Advancing Common Fixed Point Theorems In Bipolar Fuzzy-2 Metric Space And Applications In Nonlinear Analysis, Rajesh Kumar Saini, Mukesh Kushwaha

Neutrosophic Sets and Systems

This study advances common fixed point theorems (CFPT) in bipolar fuzzy-2 metric space (BF2MS) and explores their applications in nonlinear analysis. BF2MS generalizes traditional metric and fuzzy metric spaces (FMS) by incorporating dualistic relationships, allowing the representation of both attraction and repulsion effects. We extend classical fixed point theorems (FPTs) to BF2MS, establishing conditions for the existence of common fixed points (CFPs). The study's applications span nonlinear analysis, stability analysis, control theory, and multi-criteria decision-making under uncertainty. Our findings refine existing results and provide practical real-world applications, supported by numerical examples, enhancing fuzzy mathematics and nonlinear systems modeling.

Murder And Non-Negligent Manslaughter Rates In Southern And Western America, Madison Penkalski

Student Publications and Presentations

The variation in violent crime rates in the U.S. has been a persistent concern in the criminal justice system, notably homicides and offenses like murder and non-negligent manslaughter (NNM). Prior research has suggested that socioeconomic factors like poverty, firearm availability, population density, along with regional and cultural differences, could be a primary contributing factor to geographic disparities in violent crime rates. It is hypothesized that southern states will exhibit higher mean murder and NNM rates than those in western states. Crime data was collected from the Statista database and from the U.S. Census Bureau. Descriptive statistics were used to summarize …

Reconstructing Nebraska’S Late Quaternary Paleoenvironment, Landscape Change, And Human–Environment Dynamics Using Diatoms And Optically Stimulated Luminescence Dating, Gosia Mahoney

Dissertations and Doctoral Documents, University of Nebraska-Lincoln, 2023–

This dissertation examines Holocene environmental change and human–environment interactions in the Nebraska Sand Hills by integrating geomorphic, paleoenvironmental, and geochronological data. It presents three complementary studies that together explore how climatic variability, local landscape processes, and human activity influenced environmental systems.

The first study reconstructs the early Holocene evolution of a dune-dammed valley in the central Sand Hills. Stratigraphic, sedimentological, and diatom evidence indicate that eolian activity resulted in a blocked fluvial system, leading to elevated groundwater levels and the formation of a wetland that later developed into a lake. Notably, this transformation occurred under relatively dry conditions, demonstrating that …

Impact Of Bryozoans On The Psii Efficiency Of Sargassum, Maxwell Ronan Stanfield

Ocean Engineering and Marine Sciences Student Publications

Sargassum species such as s. fluitans and s. natans support epiphytic organisms on its surface, such as diatoms, hydrozoans, and encrusting bryozoans. Evidence previous studies suggests that marine epiphytic organisms have a negative effect on the photosynthetic pathways of the algae they live on (Khan, Du, Khan, Che, and Khurshid 2021; Cancino, Mufioz, Mufioz, and Orellana 1987). Interestingly, some evidence shows that even when epiphytic encrusting bryozoans limit the light reaching red algae, the algae was able to produce more photosynthetic pigments to compensate for the lowered light intensity (Muñoz, Cancino, and Molina 1991). No data is currently available on …

A Continuous Viral Vaccine Biomanufacturing Platform Utilizing Multiple Bioreactor Configurations, Justin Sargunas, Bradley Priem, Dylan Carman, Taravat Sarvari, Natalie Nold, Vaishali Sharma, Andrew Pekosz, Caryn Heldt, Michael Betenbaugh

Michigan Tech Publications

Scalable, continuous biomanufacturing processes have grown in importance to meet demand for smaller bioreactor sizes, lowered production costs, and improved quality attribute consistency. The Sf9/recombinant baculovirus (rBV) expression system demonstrates promise for virus-like particle (VLP) vaccine and gene therapy production. Here, we present a continuous rBV platform integrating an infection plug flow reactor (PFR) between stirred tank growth (gCSTR) and production (pCSTR) bioreactors. Cell expansion in the gCSTR included a ramp-up stage followed by continuous growth, reaching a steady state of 5×10 cells/mL and >90% viability. Péclet number-fit tracer studies confirmed near-ideal plug flow in the PFR, yielding a 10 …

Virtual Reality Rehabilitation And Visual Recognition Recovery After Stroke, Ivy Westfall, Brandy Whitford

Student Publications and Presentations

Every year, many stroke survivors experience challenges that go beyond movement. In addition to physical weakness, changes in thinking and vision can last long after the stroke. Most rehabilitation programs focus first on balance and motor skills. As a result, problems with visual recognition and interpretation can go unnoticed. When the temporal lobe is damaged, a person may not be able to recognize familiar faces, everyday objects, or even well-known places, even when they can see. Virtual reality (VR) has become a growing tool in stroke recovery. By immersing patients in interactive, goal-directed visual environments, VR may engage neuroplastic mechanisms …

Public Perception Of Equine Rabies And Its Implications For Future Education And Preventative Strategies, Kya Walton

Honors College Theses

This study examined the rabies knowledge, vaccination, and risks of exposures of horse owners/overseers across the state of Kentucky. Research was conducted to determine the need for public health educators and veterinarians to inform the public on rabies. Survey results concluded that respondents' general knowledge of rabies transmission and mortality rate was respectable, but knowledge relating to equine vaccination was comparatively lower. A weak inverse relationship was observed between general rabies knowledge and concern over an individual’s horses contracting rabies. A weak positive correlation was determined when looking into general rabies knowledge and the likelihood of vaccinating an individual’s horses. …

Pepper Spray Exposure And The Effect On Dna Profiling Of Blood, Brandon Schmakel

Honors Projects

Pepper spray is a common self defense tool used in both law enforcement and civilian settings, with the goal of incapacitating the sprayed individual. In real casework where pepper spray was used, a red-brown stain which tested positive presumptively for blood provided no DNA profile after further testing six months later. A previous graduate student, Emma Crawn, attempted to emulate these casework conditions and instead achieved a DNA profile with slight indications of inhibition or degradation. Further analysis of active pepper spray ingredients such as Oleoresin Capsicum (OC) and Chloroacetophenone (CN) reveals that there are observed reactions, such as oxidation, …

The True Interstellar Anisotropy Of 13 Tev Cosmic Rays, Matthew Conde

Aerospace, Physics, and Space Science Student Publications

Cosmic rays (CRs) are high-energy particles; bare atomic nuclei, with varying origins and energy levels. Research in this field is focused on identifying potential origins, understanding transport mechanisms faced on their journey to Earth, and interpreting the angular structure of incident CRs. One obstacle of this research is the trajectory modulation induced by the heliosphere during the CRs’ journey. In this work we employ a method to reconstruct the properties of CRs as they were at the local interstellar medium (LISM) by means of a nonlinear model fit to the map at Earth. Another obstacle is the time-averaging used to …
