Effects Of Multiple Stressors On Pseudomonas Fluorescens Over Short And Long Timescales, Parisa Burchfield

Electronic Theses and Dissertations

Stressors are ubiquitous factors in biological systems that result in deviations from an organism's optimal physiological state, potentially causing fitness decreases. Stressors can be biotic (e.g., predators, parasites, competitors) or abiotic (e.g., pH changes, temperature, environmental toxins). Persistent stress can lead to population declines unless organisms respond through mechanisms such as evolutionary adaptation. Experimental evolution with microorganisms, particularly bacteria, is a powerful method for studying these phenomena due to their short generation times, large populations, as well as the ability to control their environment, and freeze and revive populations. Bacteria-phage systems, such as Pseudomonas fluorescens SBW25 and its lytic phage …

Social Capital: The Link Between State Political Culture And Civic And Political Participation, Austin Marie Conner

Electronic Theses and Dissertations

Systemic racism inhibits African Americans’ civic and political participation, yet the scholarship on this topic is scarce and examines Black behavior as homogenous. This study utilizes Putnam’s social capital theory and Elazar’s state political culture typology to identify social and regional distinctions in African American civic and political behavior. Both social capital and state political culture have been linked to civic and political participation, however, not much is known about how these two constructs specifically influence African American civic and political behavior. Utilizing data from the 2016 Collaborative Multiracial Post-Election Survey, this study conducts five logistic regression models to examine …

Glycopolymeric Nanoparticles Enrich Less Immunogenic Protein Corona And Improve Tumor Delivery Compared To Pegylated Nanoparticles, Kenneth Ryan Hulugalla

Electronic Theses and Dissertations

Nanoparticles (NPs) offer significant promise as drug delivery vehicles; however, their in vivo efficacy is often hindered by the formation of a protein corona (PC), which influences key physiological responses such as blood circulation time, biodistribution, cellular uptake, and intracellular localization. Understanding NP-PC interactions is crucial for optimizing NP design for biomedical applications. Traditional approaches have utilized hydrophilic polymer coatings like polyethylene glycol (PEG) to resist protein adsorption, but glycopolymer-coated nanoparticles have emerged as superior alternatives due to their biocompatibility and ability to reduce the adsorption of highly immunogenic proteins. In this study, we synthesized and characterized glycopolymer-based poly[2(diisopropylamino)ethyl methacrylate-b-poly(methacrylamidoglucopyranose) …

From Pixels To Strings: Efficient String Art Creation Leveraging Greedy Algorithm, Ashraya Joshi

Electronic Theses and Dissertations

This thesis optimizes String Art generation using advanced algorithms. String art is a technique that creates visual artworks composed of straight lines of strings tensioned between pins distributed on a canvas. Initially employing the Hough Transform, issues such as computational complexity and edge detection inaccuracies led to adopting a Greedy Algorithm. This algorithm iteratively enhances visual similarity between the string art and the original image by reducing the difference between pixel intensities between them, significantly improving quality and efficiency. Integrating non-photorealistic rendering techniques, the study ensures smoother and more coherent lines. The study demonstrates the improvements with different quantitative metrics. …

Study Of Binary Black Hole Dynamics Using Gravitational Waves, Cody Ayres Mccammon

Electronic Theses and Dissertations

Merging binary black holes exhibit precessional motion that can be classified into three distinct morphologies: Circulating, librating around 0, and librating around π. This information is decoded from the gravitational wave signal. Binary systems can transition between morphologies as they spiral inwards, and spin precession effects are more pronounced near merger. The spin morphology reveals information about the binary black holes’ formation such as through isolated evolution of massive binary stars and their collapse or through dynamic evolution channels such as capture. In this study, we considered inferring the morphology at reference points at which the binary has (approximately) a …

Perceived Use Of True-Self-As-Guide And Decision Satisfaction In Self-Control Conflicts, Madelyn Church

Electronic Theses and Dissertations

When encountering ambiguous situations, individuals may look to their ‘true self’ to help guide their behavior and decisions (see Rivera et al., 2019). Empirical research has demonstrated that the perception of using one’s “true-self-as-guide” is beneficial in eliciting more satisfaction in decisions (e.g., Kim et al., 2021). Self-control conflicts create a unique challenge involving two aspects derived from the self: impulse and self-control. True-self-as-guide may be beneficial in feeling satisfied when navigating these situations. Through two studies, I investigated the effect that perceived use of the true self may have on decision satisfaction under self-control conflicts. Study 1 (N = …

Temperamental Fear As A Vulnerability Factor For Posttraumatic Stress Symptoms: An Examination Of Fight, Flight, Freeze Using A Trauma Film Paradigm, Jaime P. Murtagh

Electronic Theses and Dissertations

Fear is often the primary emotion associated with anxiety and stress-related disorders with research suggesting that the expression of fear varies greatly between individuals and has been hypothesized to be associated with differences in behavioral inhibition, personality, as well as temperament. One theory which has been used to conceptualize variations in temperament is the reinforcement sensitivity theory which consists of the behavioral inhibition system (BIS), behavioral approach system (BAS), and the fight, flight, freeze system (FFFS), with the latter being of particular interest in posttraumatic stress disorder (PTSD). Variations in FFFS sensitivity has been linked to variations in psychopathology with …

Structural And Binding Studies Of Marine Glycans With Potential Therapeutic Use, Hoda Alsayed Mohamed Ahmed

Electronic Theses and Dissertations

This dissertation presents a comprehensive analysis of various marine-derived polysaccharides, focusing on their structures and binding properties. Using nuclear magnetic resonance (NMR) and surface plasmon resonance (SPR), distinct marine polysaccharides were structurally characterized, and their interactions with various biological targets were evaluated. The initial study explores a glucan isolated from Marcia hiantina, a bivalve mollusk, and its biological activity. Detailed structural analysis via NMR and chromatography techniques revealed a branched glucose-based polysaccharide with potent antioxidant and anti-inflammatory properties. Further studies on the red alga Botryocladia occidentalis identified three sulfated galactans in its cell wall. Through NMR, we characterized the least …

Do Storytelling And Survival Processing Have Additive Effects On Recall Performance?, Zoe Helena Fischer

Electronic Theses and Dissertations

Both survival processing and storytelling have been shown to enhance memory performance relative to control conditions. We examined the extent to which combining these two techniques improves participants’ memory abilities relative to comparable control conditions. In one experiment, participants (n = 100) were randomly assigned to write sentences using unrelated common nouns in a sentence creation control, storytelling, survival, or survival plus storytelling condition. Participants who were instructed to write a story about survival were predicted to remember more words on a subsequent free recall test than participants in the other conditions. Mechanistically, we predict that combining predominantly item-specific processing …

Advancing College Access: A Correlational Inquiry On College Credit Attainment Among Low-Income High School Students, John Dixon

Electronic Theses and Dissertations

A college degree is vital for individuals to access lucrative, fulfilling careers. College access opportunities have existed for decades in K-12 education. In 2024, millions of high school students have access to advanced coursework, exposing them to college-level rigor with the potential to earn college credits (Jagesic et al., 2022). Students from historically marginalized communities do not participate in college courses in high schools at rates similar to White, affluent students. Furthermore, participation in these college opportunities does not always give students college credits. My quantitative, nonexperimental research study aimed to determine the extent of the relationship between the types …

Weight Discrimination And The Negative Cultural Value Of Fat: The Relationship To Well-Being Across Higher Weight Individuals Of Different Nations, Ana Clara Vieira Zaidan

Electronic Theses and Dissertations

Discrimination against individuals with higher body weights is prevalent in and outside of the US (see Pearl et al., 2021), yet research on this topic is limited when considering non-US perspectives. Cross-cultural studies had not yet explored the impact of cultural norms around weight. In the domain of anti-fat attitudes, cross-cultural research had explored variations in the negative cultural value of fatness (NCF) and its impacts across countries (Crandall et al., 2001). Incorporating this perspective, Study 1 examined how perceived weight discrimination (PWD) and NCF uniquely predict various well-being outcomes across two different countries among individuals who identified as overweight. …

A Longitudinal Study Of Mississippi’S Achievement Scores And School Ratings Based On Principal Preparation, Brittaney Boyd

Electronic Theses and Dissertations

The role of the principal is complex, and there are many ways principals might potentially influence classroom instruction and student learning (Allensworth & Hart, 2018). Over the last decade, the principal’s effectiveness has been evaluated based on student achievement.

The purpose of this quantitative study, A Longitudinal Study of Mississippi’s Achievement Scores and School Ratings Based on Principal Preparation is to determine whether a significant difference exists between Mississippi’s alternate and traditional route principal preparation graduates based on academic successes for the 2017-2018, 2018-2019, 2021-2022, and 2022-2023 school terms, whether a significant difference exists among the different Institutions of Higher …

During this expedition, two ground-penetrating radar units, a Mala GX 160 MHz antenna and a Crossover 1760 dual frequency antenna, were used to survey the basaltic, volcanic landscapes of Mauna Loa and Kīlauea. Post-eruptive digital elevation models of the Ahu’ailā’au (2018 Lower Puna) Eruption and Quantum Geographic Information Systems were used in tandem with GPR Insights software to provide a thorough picture of the surface and subsurface lava flows from Ahu’ailā’au. Using …

Standard And Non-Standard Neutrino Oscillations At The Nova Experiment, Luiz Ricardo Prais

Electronic Theses and Dissertations

Initially believed to be massless, the discovery of neutrino oscillations proved that neutrinos have masses, a feature not anticipated by the Standard Model of Elementary Particles. Investigations of the existence of the so-called physics Beyond the Standard Model is a subject of active effort in the field of particle physics. Interactions of neutrinos with matter are well described by the Standard Model, however in the presence of new physics our knowledge and ability to measure the standard neutrino oscillation parameters may be affected. Non-Standard Interactions (NSI) may arise as a subleading effect to the neutrino oscillation framework by introducing additional …

What Mediation Romantics Can Learn From The Model T (Or Maybe The Chevrolet Trax), Nancy A. Welsh

Cardozo Journal of Conflict Resolution

When mediation was reintroduced to the U.S. in the 1970s, it was infused with a democracy-and-self-determination-enhancing, social justice ethos. As the process has been very successfully institutionalized, however, these ambitions have been scaled backalthough, at least arguably, certain "mediative elements" have actually been adopted (or coopted) by other procedural innovations. Perhaps it is time for those of us frustrated with the evolution of mediation to reconcile ourselves to the reality and value of a "basic" model of mediation designed for the sole purpose of getting parties from dispute to settlement-in much the same way that the basic model of a …

Early Neutral Evaluation In Baseball Arbitration, Yakov Schwalb

Cardozo Journal of Conflict Resolution

In recent years, the contracts awarded to Major League Baseball ("MLB") players in free agency have been astronomical. In the 2023 offseason, Shohei Ohtani signed the largest contract in American sports history, a ten-year $700 million contract with the Los Angeles Dodgers. In the previous year, MLB teams spent over $3.5 billion on free agents. However, before a player is eligible for free agency, he can undergo a process called final offer arbitration ("FOA"). In this system, if a player and his professional baseball team are unable to reach an agreement for the player's salary for the upcoming season, the …

Squatters Squabbles: The Use Of Mediation To Provide Beneficial Solutions To Adverse Possession Claims In New Jersey, Bayla Zohn

Cardozo Journal of Conflict Resolution

In our society, law is a complex and ever-evolving field, constantly adapting to fit our needs. Yet, there are certain legal matters we would expect to have clear and obvious resolutions. Property ownership should be simple and unambiguous, governed by "established legal rules and precepts." Examine a deed, survey the stated legal owner of the tract of land, and your answer should be uncomplicated. Yet, there are a multitude of complex laws that allow individuals to obtain legal ownership of land in a seemingly illicit fashion.

Benzene Exposure In Reproductive Biology: A Comprehensive Analysis Of Placental Response And Molecular Mechanisms In Trophoblast Function, Anthony Maxwell

Wayne State University Dissertations

The increase in environmental challenges and exposure to pollutants like benzene poses pressing concerns for reproductive health. This dissertation investigates the impact of benzene exposure during gestation on placental function, a key determinant for fetal development and pregnancy outcomes. Our work establishes that benzene exposure during pregnancy induces maternal immune activation, leading to increased rates of fetal resorptions, compromised fetal growth, and abnormal placental development. Intriguingly, we identify a sexual dimorphic response in male and female placentas to benzene exposure, attributable to inherent differences between male and female placental biology. On a molecular level, benzene is metabolized into hydroquinone in …

The New American Conspiracism: The Conspiracy Mentality And The Consequences For American Democracy, Jennifer M. Seech Seramur

Wayne State University Dissertations

This research is at the forefront of a developing field of inquiry into the psychological impacts of an American media environment plagued with mis- and disinformation. Many have suggested that we have entered a "post-truth" era and this phenomenon will have disastrous consequences for the stability of American democracy. However, few have empirically tested these notions. This research seeks to fill part of this gap in knowledge by analyzing a survey with over 8,000 participants to bring empirical evidence to bear on these assertions. Through an assessment of the effects of a conspiracy mentality (or one’s proclivity to endorse and …

Ion Current Analysis And Misfire Prediction During Cold Start In A Compression Ignition Engine, Manan Jyotin Trivedi

Wayne State University Dissertations

In future, compression ignition engines are anticipated to continue powering heavy-duty trucks and certain machinery, while passenger vehicles and light-duty vehicles will increasingly be battery powered. However, compression ignition engines face challenges such as combustion instability, misfiring, and high unburnt hydrocarbon emissions when started under severe cold conditions. These issues can be mitigated through the use of real-time feedback to the engine's control module.

The ion current signal, reflective of combustion and emissions characteristics, has proven to be a reliable feedback signal under warmed-up conditions. In this dissertation, the potential of the ion current signal as a feedback mechanism during …
