Pilz Domain-Containing Proteins Regulate Motility In Acinetobacter Baumannii, Gabriel Smith

Electronic Theses and Dissertations

Acinetobacter baumannii is an increasingly multidrug-resistant pathogen contributing to hospital-acquired infections, necessitating a greater understanding of how it interacts with its surroundings. Many bacteria utilize different methods of bacterial motility to move about and interact with these surroundings. A bacterial second messenger, cyclic diguanosine monophosphate (c-di-GMP), can regulate various motility factors that are potentially advantageous for survival in and adaptation to their environment. Concentrations of c-di-GMP are regulated by specific synthesizing and degrading enzymes. Controlled levels of c-di-GMP allow interaction between the c-di-GMP and its binding effectors that induce changes in bacterial phenotypes such as biofilm formation and motility. A …

Transatlantic Memory And Identity: The Legacy Of Colonel Heg And The 15th Wisconsin In Norway And Norwegian America, Remi Berg

Electronic Theses and Dissertations

While memory studies of the American Civil War flourishes, ethnic and immigrant perspectives remain obscured. This project attempts to uncover how Norwegian-Americans remembered the 6000 Norwegian immigrants who fought in the Union Army. It explores the processes behind commemoration of Colonel Hans Christian Heg and the 15th Wisconsin Infantry Regiment from 1914 to 1928. It reveals that Norwegian-Americans commemorated Colonel Heg on three different and connected levels. Nationally, Norwegian-Americans raised a statue of Heg in Wisconsin after the individual determination of Waldemar Ager to challenge nativism and Americanization. Transnationally, Ager cooperated with the organization Nordmands-Forbundet who facilitated the erection of …

Co-Rumination, Psychological Inflexibility, And Internalizing Symptoms In Adolescence, John Parigger

Electronic Theses and Dissertations

Two risk factors for anxiety and depression in adolescence were examined: co-rumination, which occurs when friends excessively talk about problems; and psychological inflexibility, which occurs when one avoids negative feelings and fails to act on values. I hypothesized that psychological inflexibility would exacerbate the effect of co-rumination on adolescent anxiety and depression. Participants were 167 adolescents (Mage = 14.60 years, SD = 1.3; 65.7% cisgender males) who completed standard measures as part of an online survey. Results indicated no moderation effect, but there were main effects of co-rumination and psychological inflexibility on depression symptoms. Co-rumination may relate to …

Venturing In Limbo: Entrepreneurial Resourcefulness By The Forcibly Displaced., Sadek Showkat

Electronic Theses and Dissertations

Entrepreneurial resourcefulness is an overarching concept in the entrepreneurial process that has gained momentum among theorists and practitioners. Traditionally, entrepreneurial resourcefulness is theorized as a state—a behavior or trait—rather than a process. However, our understanding of this concept changes significantly when viewed through the lens of the lived experiences of forcibly displaced individuals. This dissertation presents a theoretical and empirical investigation of how these entrepreneurs pursue entrepreneurial resourcefulness through three interrelated essays. The first essay provides a problematizing review and introduces a novel typology (exogenous vs. endogenous) that captures the heterogeneity of the construction of entrepreneurial resourcefulness across …

Examination Of Model Minority Myth, Mentorship, University Environment, And Sense Of Belonging On The Well-Being Of Asian American Undergraduate And Graduate Students., Stephanie Chin, Stephanie Chin

Electronic Theses and Dissertations

Even though Asian Americans continue to demonstrate academic excellence and have the highest rates of completion in higher education, their psychological well-being and the factors impacting it are often overlooked due to the model minority myth (Poon et al., 2016; Mahalingham, 2013). Higher education research mainly focuses on academic outcomes (e.g., persistence and retention) and less so on psychological outcomes. This study explored and examined psychosociocultural factors, specifically internalization of the model minority myth stereotype, mentorship, university environment, and sense of belonging on psychological (eudaimonic) well-being, in order to provide a more holistic and contextualized perspective of Asian American students’ …

The Architect Of The Past: Heinrich Himmler's Remaking Of Germany's History., Chad M. White

Electronic Theses and Dissertations

This thesis explores the complex interplay between historical narratives, ideological manipulation, and cultural artifacts in Heinrich Himmler’s efforts to reshape Germany’s history during the Nazi regime. The study shows how Himmler used historical revisionism to mythologize Germanic history to support Nazi ideology. Himmler used the Ahnenerbe, an SS organization, to research and propagate distorted narratives, fabricating artifacts to legitimize the Aryan myth and assert Germanic superiority. Influenced by movements like the Völkisch Movement, Himmler's ideology relied on pseudo-historical narratives to shape public perception and Nazi policies. The study analyzes Himmler's writings and the spatial transformation of sites like Wewelsburg Castle …

Effects Of A Protection Zone In A Reaction-Diffusion Model With Shifting Bounded Habitat And Allee Effect., Davis Henderson

Electronic Theses and Dissertations

We consider a reaction-diffusion equation that models a population in a shifting bounded habitat with a protection zone and the Allee effect. We assume that the population growth function exhibits the strong Allee effect and has a positive integral within the protection zone (indicating population persistence) and a negative integral in the surrounding patches (indicating population decay). We prove that the existence of steady-state solutions to this system depends on the length of the protection zone. It is demonstrated that there exists some value H* such that, for a protection zone of size H*, there exists a solution and, for …

Carboxen Micropreconcentrator Performance For Analyzing Btex In Air., Raymond Daniel Spargo

Electronic Theses and Dissertations

Volatile Organic Compounds (VOCs) are a class of toxic chemicals in environmental air associated with several serious health risks. Some of the most common and concerning VOCs are Benzene, Toluene, Ethyl Benzene, and Xylene (BTEX). To maintain healthy air quality in these environments, researchers pursue instruments and processes to quickly and accurately predict sub-ppb concentrations of BTEX in indoor and outdoor air. By employing a micropreconcentrator (μPC) to combine Solid-Phase Micro-Extraction (SPME) with Gas Chromatography Mass Spectrometry (GC-MS) analysis, trace BTEX content in air samples can be captured, extracted and analyzed. In this thesis, a dual-compartment μPC with Carboxen 1000 …

This study is based on Beck's cognitive stress-vulnerability model of depression and previous research on (a) the increased risk for severe illnesses associated with TNF-⍺ (i.e., an inflammatory cytokine), (b) the effect of perceived everyday discrimination (PED) on depressive symptoms and TNF-⍺, (c) the association between depressive symptoms and TNF-⍺, (d) and findings that the negative cognitive triad (i.e., negative views of the self, world, and future) serves as a partial mediator between PED and depressive symptoms. The purpose of this study is to integrate Beck’s model and these different research lines by inspecting the associations between the stressor PED …

Relations Between Discrimination, Negative Attribution Style, Cortisol, And Depressive Symptoms In Adolescents., Hannah Widmer

Electronic Theses and Dissertations

The aim of our study was to integrate the chronic stressor of Perceived Everyday Discrimination (PED) into the Hopelessness Theory of Depression with a focus on the comorbidity between physical and mental health by way of depressive symptoms and cortisol in adolescents. Research has shown that cognitive diatheses mediate the relation between stress and depressive symptoms and cortisol predicts depression. We hypothesized that Negative Attribution Style (NAS) and cortisol would mediate the relation between PED and depressive symptoms. Altogether, 99 adolescents (mean age: 14.10 years, 36.4% female; 63.6% male; ethnicity: 2% Latinx; 98.2 % non-Latinx; race: 41.4% Black, 34.8% White, …

Manipulation Of Cellular Proliferating Cell Nuclear Antigen (Pcna) During Herpes Simplex Virus Type 1 Infection, Jessica Packard, Jill A. Dembowski

Electronic Theses and Dissertations

Herpes simplex virus type 1 (HSV-1) is a double stranded DNA virus that replicates within the nucleus of host cells. Using accelerated native isolation of proteins on nascent DNA (aniPOND), cellular proteins were found to associate with HSV-1 replication forks. One host factor of interest is proliferating cell nuclear antigen (PCNA), the DNA sliding clamp that tethers DNA polymerases and DNA damage response proteins to replicating cellular DNA. Although HSV-1 encodes its own DNA polymerase processivity factor (UL42), PCNA plays a key role in HSV-1 infection. We used commercially available PCNA inhibitors and short hairpin RNAs (shRNA) to investigate how …
