Developing A Global, Multi-Decadal (1983-2017) Convection Tracking Database Utilizing Isccp Hxg Data, Yuliya Selevich

Dissertations and Theses

Deep convective systems play a crucial role in Earth's climate system, yet tracking their behavior over large spatial and temporal scales remains challenging. This study introduces a new global convection tracking database spanning July 1983 to June 2017, developed using the ISCCP H-Series Pixel-Level Gridded (HXG) dataset and the object-based TOBAC (Tracking and Object-Based Analysis of Clouds) framework. By applying multi-threshold feature detection, segmentation, and linking algorithms to infrared brightness temperature fields, convective systems are systematically identified and tracked through their life cycles. The resulting database provides a rich set of structural, dynamical, and radiative properties for over 67 million …

Political Regimes And Social Well-Being In The Sahel: An Analysis Of Gendered Development And Children's Education, Binta Fv Diarra

Dissertations and Theses

This thesis explores how divergent governance structures in the Sahel, specifically in Burkina Faso, Chad, Mali, and Senegal, affect the region's human development. Emphasizing gendered vulnerabilities and education, the research examines how political structures and leadership priorities deeply influence access to education and healthcare, specifically for women.

Authoritarian regimes often centralize power and prioritize regime stability over public welfare, leading to chronic underfunding of education and health services. In Mali and Burkina Faso, repeated coups and insecurity have affected schools and hospitals, disproportionately affecting girls and displaced women. Chad's one-party dominance reflects how systemic exclusion and poor service delivery entrench …

Examining Drug Policy In Portugal And Greece, Collin Fernandes

Dissertations and Theses

This thesis examines the divergent drug policies implemented in Portugal and Greece, analyzing why Portugal's comprehensive decriminalization model has been more successful than Greece's partial approach. Since 2001, Portugal has pioneered a drug policy that decriminalizes all drugs for personal use while investing in harm reduction services, rehabilitation, and social reintegration. In contrast, Greece maintained criminalization while implementing more limited harm reduction measures, particularly through OKANA (the Organization Against Drugs). The research highlights how economic factors, particularly the 2008 financial crisis and austerity measures, negatively affected both countries' programs but hit Greece's initiatives with greater severity. Portugal's programs have remained …

Examining The Complex Interplay Of Stress, Social Support, And Drinking Motives On Alcohol Use Behaviors: A Moderated Mediation Model Among College Students, Sabrina Perrin

Dissertations and Theses

College student alcohol use remains a public health concern, yet the psychological and social mechanisms that contribute to high-risk drinking patterns are not fully understood. Guided by the motivational model of alcohol use and stress-buffering theory, this study tested a moderated mediation model to examine how perceived stress, coping motives for drinking, and perceived social support interact to influence alcohol use behaviors. A sample of over 1,100 diverse urban college students completed measures of stress, social support, drinking motives, and four alcohol-related outcomes: binge drinking, frequency of alcoholic drinks consumed, negative drinking consequences, and use of protective behavioral strategies (PBS) …

Testing An Educational Intervention To Improve Recognition And Understanding Of Emotional Manipulation In Romantic Relationships, Tiss Zaitz

Dissertations and Theses

Romantic relationships significantly impact happiness and well-being, yet rarely is it taught how to build them or recognize unhealthy relationship dynamics. This gap has profound implications, as Emotional Manipulation (EM) can have severe and lasting consequences. This study examined whether an educational intervention could improve participants' ability to recognize and understand EM in interpersonal relationships. Participants (N = 327) completed a pretest assessing recognition and comprehension of EM and were then given an answer sheet with detailed explanations to enhance understanding. A subset (n = 46) completed a posttest to measure changes in recognition and knowledge. Results showed significant improvement …

Unveiling Invisible Wounds: Experiences Of Racial Microaggressions, Racial Gaslighting, And Mental Health Among Racially And Ethnically Minoritized Adults, Supriya Pandit

Dissertations and Theses

Racial microaggressions are momentary, subtle, and often unintentional comments or behaviors that nonetheless communicate negative race-based messages towards racially and ethnically minoritized individuals. Given the accumulated and differential impact of racial microaggressions on individuals' mental health over time, it is crucial to investigate its associations with specific mental health symptoms and intrapsychic alleviating factors. To further clarify which coping strategies for racial microaggressions can be more empowering versus harmful, it is also crucial to investigate the processes and mental health consequences that unfold when individuals choose to challenge racial microaggressions, such as racial gaslighting. Racial gaslighting is an insidious interpersonal …

The Transformative Power Of An Ethic Of Care In Patricia Piccinini’S Mythic Posthuman Offspring, Keely Parrish

Dissertations and Theses

This thesis examines the contemporary artist Patricia Piccinini and her posthuman hybrid creations within the context of a feminist ethic of care. Largely referring to scholarship by the political scientist Joan C. Tronto, I argue that Piccinini expands the definition of an ethic of care to include non-human entities as well as human ones. The four phases of care identified by Tronto will serve to outline the encounter between the audience and Piccinini’s work to see how humans and non-humans (1) care about, (2) take care of, (3) give care and (4) receive care from each other, as well as …

Revelations: Spirituality As Privileged Perspectivism In Magical Realist Distortions, Isabella Scala-Kazanecki

Dissertations and Theses

This thesis examines the role of spiritual beliefs in the literary mode now known as magical realism in Cuban Alejo Carpentier’s The Kingdom of This World (1949), Indian-Born British and American Salman Rushdie’s The Satanic Verses (1988), and a lesser-known novel, Household Saints (1981) by Francine Prose, an American writer. The Kingdom of This World, itself the originator of the mode of magical realism, has allowed me to conclude with Carpentier that magical realism arises from “privileged revelations,” as he notes in the preface to his seminal book. But these revelations in magical realism are not necessarily always of the …

Living By The Sword: Religiosity And The Terrorist Subculture Of Russian Revolutionaries, 1904-1910, Gregory I. Mcevoy

Dissertations and Theses

The Marxist dictum of “religion is the opiate of the masses” has led to a prevailing assumption in scholarship that the socialist movements of the early twentieth century have been inherently atheistic. Religion is often associated as a remnant of old, antiquated society and incompatible with the claimed modernity of socialist progress. This assumption has led to overlooking the religiosity within certain radical movements and revolutionary culture at large. Scholarship on the political underground in Tsarist Russia has, thus far, perpetuated this impression. While it is the true that the Bolsheviks and Leninist Social Democrats rejected religion as obscurantist and …

Defining ‘Un-Americanism’ In Culture And Art: The Dies Committee’S Investigation Of The Federal Theatre Project, Matthew G. Summers

Dissertations and Theses

This thesis explores the House Un-American Activities Committee’s (HUAC) expansive definition of ‘Un-Americanism’ through the body’s 1938 investigation of the Federal Theatre Project (FTP). The committee, then known as the Dies Committee after its chairman Martin Dies (D-TX), publicly presented the hearings as an attempt to root out communism in a deeply compromised government program. And indeed the FTP, an ambitious New Deal Program to provide work for unemployed professionals in the theatre, had an undoubtedly leftist bent. However, the hearings were consistently focused on the project's progressive stances on issues of race and gender, and effectively exposed the underlying …

Cosmopolitanism Now: Fragmented Belonging, Adriana Fischetti

Dissertations and Theses

Abstract

This thesis reconceptualizes cosmopolitanism for the contemporary moment as fragmented belonging, critiquing and moving beyond traditional cosmopolitan frameworks grounded in universal reason, seamless integration, or coherent identity. Through close readings of Teju Cole’s Open City and Tremor, and Mohsin Hamid’s The Reluctant Fundamentalist and Exit West, this study argues that cosmopolitanism today emerges explicitly from rupture, contradiction, and ethical struggle, shaped fundamentally by conditions of displacement, empire, surveillance, and global capitalism. Engaging critical theorists such as Kwame Anthony Appiah, Homi Bhabha, Pheng Cheah, and Roland Barthes, the thesis identifies fragmented belonging as an ethically charged response to …

The Sand Creek Massacre And The History Of Greater Reconstruction In The American West, Anna E. Plotnick

Dissertations and Theses

In the traditional U.S. historical narrative, the Civil War & Reconstruction era is a North vs. South story. Nevertheless, the era of western expansion, a central theme throughout the nineteenth century, has no contingent place within this traditional narrative. Meanwhile, the history of the American West and its diverse peoples appears in many textbooks as an unrelated albeit contemporaneous narrative. Separated by geographical regions, historians often do not examine these concurrent histories. However, many of these historical events and actors were interconnected. As I am interested in understanding the Reconstruction era’s national impact, I intend to explore how Reconstruction policies …

Essential Caretaking For Artists With Disabilities: Exploring The Overlooked Histories Of Hazel Knapp And Grandma Moses, Bryan P. Martin

Dissertations and Theses

This thesis explores the intersection of disability studies and art history, addressing the underrepresentation of disability in scholarship, especially concerning medical sociology and caretaking. Focusing on two early-twentieth-century self-taught American artists, Hazel Knapp (1908–95), who fell into obscurity, and Anna Mary Robertson Moses (1860–1961), best known as Grandma Moses, this is a comparative analysis of how disability influenced their artistic practices and shaped their divergent career outcomes. Knapp was born with Charcot-Marie-Tooth disease, a neurodegenerative disorder, and fell into obscurity due to a lack of support for her condition, but experienced a promising start to her career that included patronage …

Mental Fatigue Effect On Joint Repositioning, Collin Kehrwald

Dissertations and Theses

Mental fatigue influences both cognitive and physical performance, but its specific effects on proprioception have not been widely explored. This study aimed to examine how mental fatigue affects shoulder and knee joint repositioning senses. A joint repositioning task was used to assess proprioception in 18 college-aged males, with measurements taken for both shoulder and knee joint angles before and after a mental fatigue-inducing intervention. The Stroop task was employed to induce mental fatigue between the conditions. Results showed a significant increase in shoulder flexion variable error (p = 0.01, pre-Stroop = 2.79 ± 1.31 degrees, post-Stroop = 4.97 ± 3.20 …

Blattella Germanica As A Vector Of Salmonella Typhimurium, Matthew Turner

Dissertations and Theses

The following investigates the role of the German cockroach (Blattella germanica) as a vector of the bacterium Salmonella enterica subspecies enterica serovar Typhimurium (S. Typhimurium). As such, this work examines various host-pathogen-microbiome interactions that define the vectorial capacity of the German cockroach for Salmonella. To date, the majority of literature focuses on the general association of the German cockroach with various human pathogens, claiming any dissemination to be carried out via passive mechanical transmission. This project recognizes those claims, while expanding to include the possibility of biological transmission, involving active and complex host-pathogen interactions, including mechanisms like replication within the …

The Third Person Effect: Misinformation And Disinformation Of News On Racism, Jody-Ann Kadine Tyson

Dissertations and Theses

The increased proliferation of misinformation and disinformation has been a cause for concern in the 21st century, as it has had significant repercussions on societal systems and the overall livelihood of individuals. Additionally, a 2016 study revealed that 84% of the American respondents are confident in their ability to detect misinformation and disinformation, while 64% believed that misinformation and disinformation made others confused about current affairs and events (Barthel et al., 2016). These results confirm that some people are not cognizant of the effects of media messages on themselves, but on others (TPE). Due to this implied ignorance, the spread …

Investigating Trauma-Informed Practices Impact On Teacher Well-Being And Burnout, Philip Walter Schonebaum

Dissertations and Theses

Trauma-informed practices are a way to reduce the negative impacts of trauma without retraumatizing trauma victims (SAMHSA, 2014). Using trauma-informed training for staff, this study herein sought out to examine the overall impacts on utilizing trauma-informed care strategies on teacher well-being and burnout. The action research project, relying on qualitative data collection techniques, was an immersive approach to impact change in the educational landscape of a small, rural school district. Findings showed implementing trauma-informed practices in the school district led to a greater job satisfaction, reduced stress, and a sense of camaraderie with the students within the school.

Educational Trouble In Paradise: Student Perception Of Teaching Behaviors And It's Relation To Intrinsic Motivation And Academic Achievement, David Mchale Davis

Dissertations and Theses

Grounded in self-determination theory, this study explored students’ perceptions of provision of choice, teacher feedback, and emotional support, and how these teaching behaviors relate to intrinsic motivation and academic achievement. This study is a cross-sectional survey design and has data from 197 public high school students in the Bahamas. Path analysis was used to evaluate a model in which the three teaching behaviors predicted intrinsic motivation, which in turn was hypothesized to mediate their effects on academic achievement, measured by GPA, math grade, and students’ perceived likelihood of graduating. Results supported the model, indicating that higher levels of perceived teacher …

Barbara Strozzi (1619-1677): Empowerment In The Life And Madrigals Of The Venetian Virtuosa, Abigail Rockhill Beckler

Dissertations and Theses

It is generally agreed upon that studying underrepresented women composers is vital to expanding the breadth of musical study prior to 1900. However, when teaching about lesser-known women musicians, it is often misconstrued that these women were simply “granted” a musical career by a man within their network, and that because society would not allow them a chance otherwise, the woman had little say in what happened next. This study will show that Venetian composer and virtuosa Barbara Strozzi (1619–1677) exemplifies the early woman composer who had personal agency in the flourishing of her career. While Strozzi was allowed certain …

Social-Emotional Learning In Out-Of-School Time Settings: A Mixed Methods Investigation Of Perceived Need, Kaitlin Halbert

This study examines the integration of Social and Emotional Learning (SEL) into Out-of-School Time (OOST) settings. It evaluates the perceived need for SEL curricula among OOST professionals, highlights potential benefits and barriers to implementation, and identifies necessary adaptations to tailor these programs for the unique OOST environment. Using a mixed-methods explanatory sequential design, including surveys (BIRS, URP-NEEDS, URP-IR) completed by 115 OOST providers and interviews with 10 providers, the research analyzes both quantitative and qualitative data. The results demonstrate a strong consensus among OOST professionals on the importance and value of SEL, acknowledging its potential to enhance student behavior, social …

Calcium Carbonate Microparticles As Acid Responsive Targeted Drug Delivery Carriers For Oral Diseases And Its Anti-Bacterial Activity, Hem Raj Joshi

Dissertations and Theses

Dental diseases are mostly caused by bacterial infections in the teeth, forming biofilms that release acids and decay the enamel of the teeth. More than half of the world's population were affected by oral diseases, including periodontitis (gum disease), dental caries (cavities), and oral cancer. Chlorhexidine (CHX) is the mostly used antimicrobial drug for dental diseases, but its overexposure to the healthy teeth causes many side effects, such as tooth staining, taste alteration, and many more. Taking advantage of the acidic environment of infected teeth, we designed a pH responsive targeted drug delivery system using calcium carbonate microparticles (CCMPs) as …

Convergence In Cancer: Integrative Multi-Modal Modeling For Pan-Cancer Drug Response Prediction, Jessica Zylla

Dissertations and Theses

Heterogeneity and rarity can make cancer difficult to study and treat. Cancer's heterogeneity, evident in tumor locations, tumor cell types, subtypes, and microbiota within the tumor microenvironment, complicates diagnosis, prognosis, and treatment. Research into the tumor microenvironment and its microbiota is an evolving area of oncology that may advance cancer drug-patient response. Cancer-omics signatures are crucial to drug response, yet there is no tool that physicians use as a gold standard. Research indicates that microbial presence can alter drug metabolism and immune response, affecting cancer-drug efficacy on a patient-specific basis. This work highlights the need for training readiness in transdisciplinary …

Schools Apart: Curricular Stratification Across School Socioeconomic Compositions And Implications For Educational Inequality In The Us, Daniel Mackin Freeman

Dissertations and Theses

Motivated by longstanding sociological theories and utilizing the most current, large, and nationally representative data, this dissertation aims to describe and add nuance to our understanding of how the curriculum US youth are exposed to is stratified by the socioeconomic composition of the schools they attend. All three empirical chapters suggest that school SES contributes to substantial differences in school structure, as evidenced by differences in course-taking patterns and how course-taking relates to academic achievement in high school and beyond. The first study suggests that the relationship between curricular intensity in secondary school and postsecondary achievement is variable depending on …

Video compression, however, can significantly mitigate these …

A Mechanistic Study Of Silicon Nanocrystal Formation Via Solid State Synthesis, Katherine Mccarthy Weinfurter

Dissertations and Theses

Silicon nanocrystals (SiNCs) show promising physiochemical properties that could be used in industrial applications. The production of SiNCs through solid-state synthesis is ideal due to relatively low cost of equipment and chemical reagents, as well as the ability to scale-up production. A widely known and commonly used precursor previously used in solid-state synthesis for SiNCs, hydrogen silsesquioxane (HSiO_1.5), was discontinued in chemical manufacturing, which has led to researching alternative precursors (or starting materials). We have identified that there is a gap of knowledge related to producing these precursors, as well as the mechanistic understanding of the chemical reactions …

Tag-Based Security In C: Writing And Specifying Flexible Protection, Sean Noble Anderson

Dissertations and Theses

The C language is ubiquitous and insecure. Tag-based security policies offer a flexible toolkit for runtime protection, including policies that mitigate the effects of undetected programming bugs and those that enforce security properties of the program logic. But tag policies can be difficult to define, and the protection that they offer can be difficult to specify and to prove.

This dissertation builds from an assembly-level specification of stack safety, encompassing the essential control-flow structure of C and other high level languages, to a C source-level policy definition framework called Tagged C. Tagged C includes a variant C semantics parameterized by …

Investigating Student Expectations, Buy-In, And Engagement In Lower Division Undergraduate Chemistry Labs, Elizabeth Blanche Vaughan

Dissertations and Theses

Laboratory courses constitute an integral aspect of chemistry education at the undergraduate level. Despite their prominence, a growing number of researchers have begun to think more critically about the value of laboratory learning experiences. As pedagogical decisions should be based on evidence, it is necessary for chemistry education researchers and practitioners to investigate the claim that teaching laboratories are a valuable part of science education. Therefore, the aim of this dissertation was to address one small section of this gap in the literature by obtaining a more robust understanding of students' expectations, buy-in, and engagement in lower division, undergraduate, chemistry …

Recovery Of Black Carbon Concentrations In Burned Forests In Wyoming, Usa, Monica Vanesa Zapata Villegas

Dissertations and Theses

Burned forests that remain standing following fire release light-absorbing particles (LAPs), including black carbon (BC), into winter snowpacks, reducing snow surface albedo and accelerating snowmelt timing for decades postfire. Although the role of LAPs in seasonal snow has been extensively studied, the spatiotemporal variability of LAPs' contributions to snowmelt relative to time-since-fire and burn severity remains unknown. This study aimed to quantify the spatiotemporal variability of forest fire effects on LAPs in snow and associated snow albedo in the Triple Divide region of western Wyoming, headwaters of the Colorado, Columbia, and Missouri rivers. Using geochemical analysis and radiative transfer modeling, …
