An Investigation Of The Impact Of Canadian Wildfires On Us Air Quality Using Satellite, Model And Ground Measurements, Zhixin Xue

Dissertations

In recent years, frequent and widespread wildfires in Canada have become the “new normal” during summer, which degrades the U.S. air quality significantly. Smoke from wildfires in British Columbia and Alberta can be transported by northwesterly winds to the U.S. and cause health issues to vulnerable populations, which also increases the health costs to the country. During the fire season, daily PM2.5 in cities along the smoke transport path in the United States can increase 5 to 10 times compared to pre-fire values. This research examined different processes affecting smoke's vertical and horizontal transport and quantified the increase in fine …

Examining The Relationship Between Child Maltreatment, Executive Functioning, And Trauma Appraisal, Myshira Oliver

Dissertations

Problem

A current problem is that although child maltreatment has been demonstrated to be negatively associated with both executive functioning and trauma appraisal (leading to feelings of shame, self-blame, etc.), there is not an established model within the literature that explains the relationship between child maltreatment, executive functioning, and trauma appraisal. The purpose of this study was to develop a model that displayed the relationship between child maltreatment, executive functioning, and trauma appraisal. Additionally, this study sought to discover differences in trauma appraisal and executive functioning based on the type of child maltreatment experienced.

Method

This study employed a quantitative, …

Understanding The Process Of Health Goal Achievement Among Black Men Who Have Sex With Men (Msm) In Chicago: An Exploratory Qualitative Study, Anthony Johnson

Dissertations

Background: Over the last 30 years, Black men who have sex with men (MSM) have been disproportionately affected by HIV/AIDS while accounting for only approximately 1% of the population of the United States. The majority of research with Black MSM has focused on HIV infection risk factors, but very little attention has been given to their overall health and well-being. The breadth of HIV-health related research that includes Black MSM tends to demonstrate high levels of racial, environmental, and economic disparities that need to be addressed. However, more research must be conducted to explicate the process of exercising strength and …

Dissertations

Un- and under-insured individuals have lower access and less health literacy than their insured counterparts. This is a major public health problem as lower health literacy leads to unhealthy communities which have higher chronic disease rates. This quantitative dissertation uses data from a public health hospital system to understand the relationship between health literacy and healthcare utilization. The Andersen Model has been applied to determine whether, or to what extent, health literacy explains the relationship between the identified predisposing and enabling factors and the outcomes of appropriate utilization of care by controlling for variables associated with health literacy. A sample …

Rhodium-Catalyzed Decarbonylation Of Aroyl Chlorides, Wiktoria M. Koza

Dissertations

The development of efficient strategies for the synthesis of aryl–halogen bonds is highly desirable due to the prevalence of these moieties in pharmaceuticals, agrochemicals, and organic synthesis. Although there are numerous applications of aryl chlorides in chemistry, an efficient strategy for the preparation of these molecules is underdeveloped. Transition metal-catalyzed decarbonylation provides an efficient and selective approach for aryl–halogen bond formation. There has been significant progress in the development of new decarbonylation strategies, particularly involving aldehydes for the synthesis of new carbon–hydrogen (C–H) bonds or for cross-coupling reactions. However, transition metal-catalyzed decarbonylation methods for carbon–halogen (C–X) bond formation have been …

Maternal-Fetal Attachment And Its Relationship To Quality Of Life In Pregnant Women With Diabetes, Cheryl Ann Angel

Reclaiming The Patria: Sinarquismo In The United States, 1936-1966, Nathan Ellstrand

Dissertations

This dissertation examines the rise and fall of the Catholic, nationalist, and anti-communist Mexican Unión Nacional Sinarquista (UNS or National Synarchist Union) in the U.S. between 1936 and the 1960s. Whereas most scholars study the UNS as a Mexico-specific movement, I examine the organization as a transnational one. This project not only adds to the literature on the UNS, but in Mexican American, Western, and postrevolutionary Mexican history. The individuals that became sinarquistas found refuge from the Mexican church-state conflict in the U.S. in places such as Texas, California, and Chicagoland. The organization’s leadership therefore envisioned an expanded Mexico wherever …

The Souls Of Black Folks In The Twenty-First Century: Self-Efficacy, Grit, And Their Development In Low-Income Urban Black Youth, Amzie Moore

Dissertations

Self-efficacy and grit have shown to be internal resources for African American youth, particularly urban low-income youth living in high crime and high poverty communities. This dissertation is a quasi-experimental, longitudinal, and mix method study, which evaluated a cross-age peer mentoring program. This evaluation was to examine if youth mentors’ attendance in the program for one year predicted increases in their self-efficacy and grit. The results of the study revealed that age significantly interacted with youth attendance, predicting increases in self-efficacy. Findings from the qualitative analyses illustrated that the peer-mentoring program strengthened culturally-relevant self-efficacy and grit among youth mentors.

Leveraging Moral Foundations To Increase Covid-19 Vaccination, Cara Elizabeth Ray

Dissertations

Despite the vast majority of the eligible U.S. adult population being vaccinated against COVID-19, geographical clusters of unvaccinated individuals pose a substantial risk of outbreak. It is important to encourage as many individuals as possible to vaccinate against COVID-19 to reduce its spread and severity. Past research has identified endorsement of the purity and liberty moral foundations – intuitive domains of moral concern – as predictors of vaccine hesitancy and political conservatism, while conservatism is itself associated with vaccine hesitancy. Across two online surveys, I examined the effects of a message invoking the purity and liberty foundations as well as …

The Role Of Glycogen Synthase Kinase 3 Β (Gsk-3Β) At The Cardiac Myofilament, Marisa Jean Stachowski

Dissertations

Altered kinase activity and localization is gaining appreciation as a mechanism contributing to cardiovascular disease. Previous work suggests that the kinase glycogen synthase kinase 3 β (GSK-3β) regulates contractile function of the myofilament, but this work was performed in vitro. The goal of this work was to investigate GSK-3β’s in vivo role in regulating myofilament function, the mechanisms involved, and the translational relevance in disease. GSK-3β’s myofilament localization was confirmed in wild type mouse and human tissue via western blot of myofilament enriched tissue and immunofluorescence. These experiments also revealed that GSK-3β phosphorylated at Y216 binds to the z-disc. We …

Housing insecurity is one of the main drivers of poverty and inequality in contemporary urban society. We know that this insecurity contributes to poor outcomes for the individuals experiencing it. We know less about how this housing insecurity impacts contact with the criminal justice system. Using event history analysis, this study assesses the effects of housing insecurity in Polk County Iowa and Palm Beach County Florida. Results confirm that housing insecurity increases the risk of being rearrested each day a person is without stable housing. These findings reveal that lack of access to safe, affordable, and stable housing not only …

Does Co-Speech Gesture Support Children’S Analogical Reasoning? An Investigation Into The Differential Effects Of Gesture On Learning, Amy Michelle Wilkinson

Dissertations

A well-established conceptualization of academic capitalism is rooted in the marriage of economic theory and critical social. Significantly, academic capitalism links economic dimensions with the political-ideological transformations of U.S. society associated with the fall of communism and the rise of neoliberalism. Academic capitalism is based on a recognition of the paradoxical nature of higher education and offers a lens through which to examine the ways in which institutions in the United States have come to prioritize learning for the labor market as a private good within the new global economy, while also becoming less beholden to the notion of learning …

Dark Patterns: Effect On Overall User Experience And Site Revisitation, Deon Soul Calawen
