Early Childhood Foundations Of Adolescents' Critical Consciousness In Under-Resourced And Minoritized Communities: The Roles Of Prosocial Behavior And Cognitive Self-Regulation In Middle Childhood, Zahra F. Naqi-Hasnain

Dissertations

As Black and Latino teens from under-resourced backgrounds remain vulnerable to oppressive forces, critical consciousness has emerged as a developmental asset that involves understanding, reflecting upon, and acting against inequitable social structures. However, scholars have yet to determine how critical consciousness may fit into a developmental framework, leaving unanswered questions regarding the roots of adolescents’ critical consciousness. By integrating sociopolitical and developmental frameworks, this dissertation empirically examined how early environmental factors and individual competencies set the stage for critical consciousness during adolescence, via prosocial and self-regulatory skills during middle childhood. Longitudinal data were drawn from the Chicago School Readiness Project …

Identifying And Characterizing Cognitive Profiles In Midlife Females: A Latent Profile Analysis, Hannah Hagy

Dissertations

Females are at two-thirds greater risk of developing Alzheimer’s disease (AD) than males. Due to this notable sex difference in cognitive aging and disease burden, there has been an increased focus on understanding the critical role of the menopausal transition (decline in fertility during midlife) as it relates to cognitive functioning across midlife. Thus, the present cross-sectional study used a sample of midlife females at different stages in the menopausal transition (N=202; Age 40-60 years) as part of a larger, multimodal design study, to elucidate distinct cognitive profiles while accounting for education, which were then characterized by other demographic factors, …

Multiracial Congregations: Transformative Or Status Quo?, Michelle Dodson

Warm Bodies, Strong Attachments, And The Search For Better Bonds: The Politics Of Human-Animal Entanglements In U.S. Fiction And Media, John Charles Hawkins

Dissertations

This dissertation describes human-animal relationships as sites of political longing and meaningful failure in the context of twentieth and twenty-first U.S. fiction and media. I locate three tendencies of imagination prevalent in writing about bonds between humans and other animals: collaboration in regional modernity, refamiliarization in consumer capitalism, and transformation in rationalist patriarchy. These expressions of desire for a different way of relating, I argue, open important windows into the places where current power structures generate suffering and distress. I also emphasize the compelling but imperfect nature of these expressions. The texts and images in this dissertation offer attempts to …

Development And Benchmark Of Polarizable Models For Ions, Luke Landry

Dissertations

Metalloproteins are ubiquitous in biology, playing crucial roles in diverse processes. Meanwhile, molecular simulations have become an important tool in scientific research. To accurately simulate metalloprotein systems, accounting for polarization and charge transfer effects is required. The fluctuating charge (FQ) model can effectively simulate the charge transfer effect, but the existing models often lack specificity for metalloproteins. In our research, a tailored FQ model for zinc-containing metalloproteins, leveraging the extended charge equilibration (EQeq) scheme, was introduced. CM5 charges were used as the target in our model parameterization, which offers advantages over RESP/CHELPG charges. Most notably, CM5 charges hold independence over …

Multi-Label Classification Using Conformal Prediction, Chhavi Tyagi

Dissertations

In many machine learning applications, such as image tagging, document classi-fication, and medical diagnosis, a data instance can be associated with multiple classes in parallel so that each instance is associated with multiple response variables simultaneously defining multi-label classification. Standard multi-label classification methods that provide point predictions have been developed. They lack in quantifying the uncertainty of predictions. These methods also lack in accounting for label dependencies and are very computationally expensive. This dissertation develops two methods of multi-label classification using conformal prediction that quantify the uncertainty of predictions. Chapter 1 introduces notations and tools that have been used in …

Investigating The Neurovascular Correlates Of Cognitive Function In Individuals With Spinal Cord Injury Using Functional Near-Infrared Spectroscopy, Donna Yali Chen

Dissertations

Individuals with spinal cord injury (SCI) have a 13 times greater risk of cognitive impairment than able-bodied individuals and commonly report symptoms of depression and anxiety. The reports of cognitive impairment in individuals with SCI are independent of concomitant brain injury. Although the direct cause of cognitive impairment in individuals with SCI is unknown, key contributors may include comorbid depression, chronic pain, anxiety, fatigue, brain injury, or cardiovascular dysfunction. Previous studies have focused on SCI at the level of the spinal cord but have under-investigated the supraspinal levels. Due to the lack of neuroimaging studies on SCI rehabilitation, it is …

Certifying Stability In Runge-Kutta Schemes: Algebraic Conditions And Semidefinite Programming, Austin Juhl

Dissertations

Numerical stability is a critical property for a time-integration scheme. In the context of Runge-Kutta methods applied to stiff differential equations, A-stability is one of the most basic and practically important notions of stability. Dating back to the work of Dahlquist, it has been known that A-stability is equivalent to the Runge-Kutta stability function satisfying a particular convex feasibility problem. Specifically, up to a transformation, the stability function lies in the convex cone of positive functions. In recent years, sum-of-squares optimization and semidefinite programming have become valuable tools in developing rigorous certificates of stability in dynamical systems. Therefore, it is …

Electrified membrane filtration presents a robust alternative, utilizing minimal or no chemical additives and harnessing electrical power to directly reduce contaminants or produce reactive oxidants or reductants on-site.

This dissertation is dedicated to the development of innovative electrochemically reactive membranes designed to address three major challenges: (1) the engineering of electrocatalysts with …

A Methodological Framework For Ontology Development, Enrichment, And Application In Natural Language Processing Tasks, Navya Martin Kollapally

Dissertations

Electronic Health Records (EHRs) have been widely used in healthcare to record demographics, vital signs, test results, immunizations, medical imaging reports, differential diagnoses, etc. It is now accepted that non-clinical (e.g., social) factors have a substantial influence on health outcomes. Hence, it is desirable to record these Social and Commercial Determinants of Health (SDoH & CDoH) in an EHR. The "non-text parts" of EHR notes (e.g., data tables) rely on coded terms from underlying ontologies or terminologies to facilitate semantic interoperability. Ontologies help define concepts, the relationships between them, and instances that can be utilized in research.

The first accomplishment …

Large Deviation Theory In Stochastic Processes: Applications To Biological Modeling, Moshe C. Silverstein

Dissertations

This dissertation delves into developing and applying stochastic models to analyze complex biological systems. It leverages Large Deviation Theory (LDT) to gain insights into these systems, focusing on two key examples: neural networks and calcium signaling dynamics. Traditional deterministic methods frequently fail to capture biological processes' randomness and inherent variability. Meanwhile, many stochastic approaches struggle to be mathematically tractable or provide accessible insights. The approach introduced in this study provides rigorous mathematical frameworks to enhance understanding of these stochastic behaviors while remaining tractable and insightful.

A stochastic model for a random biological neural network is constructed that addresses the dependencies …

Caregiver Support For Patients Diagnosed With Dementia, Michelle N. Kabakibi

Dissertations

Background: Current research indicates that caregivers of dementia patients often experience a great deal of stress related to caregiving. Most of these caregivers are informal caregivers without prior knowledge or training in dementia care. Previous studies indicate that informal caregivers often experience stress during this postdiagnosis period due to a lack of high-quality and available information, education, and support services tailored to meet the unique needs of families caring for a dementia patient. Currently published approaches to providing caregivers with information are largely centered on a one-size-fits-all approach.

Purpose: This descriptive qualitative study was conducted to examine the lived experience …

An Autoethnography Of A Social Justice-Minded Teacher In Corrections, Graciela Rubalcaba-Munoz

Dissertations

ABSTRACT The incarceration of women has increased 93% in the last fifty years. This impacts marginalized communities at disproportionate rates. Although the provision of education in corrections became federal law in 1952 as a means to rehabilitate inmates, women’s facilities currently do not receive equitable resources to support education, which puts additional pressure on the educational staff. The legal requirement for education includes county jails, the transitory facilities that house inmates while they await court or transfer to prison. The jail educational system is volatile, making it difficult to engage students when there are constant interruptions, unexpected incidents, lockdowns, and …

Exploratory Study Of Graduate Nursing Student Grit And Strategies Used By Their Faculty: A Mixed Methods Approach, Leanne T. Burke

Dissertations

Registered Nurse (RN) workforce projections continue to show a shortage of RNs, which will intensify as Baby Boomers age and large numbers of nurses reach retirement (AACN, 2017a). To meet workforce demands, increasing numbers of nurses prepared at the graduate level for advanced roles like nursing faculty, nurse researchers, and primary care providers are critical. With variable attrition rates in master's and doctoral programs, there is a need for research into the uniqueness of these populations. In particular, noncognitive predictors of success, such as grit, may be important. This explanatory sequential mixed methods study assessed grit levels (measured by Grit-S) …

It is argued that the midrash technique in the Prologue serves to persuade the audience to perceive itself as a religious other. Through John’s use of the midrash technique in the Prologue, there is an engaged effort to create boundaries and construct a new identity for his community. The choice of vocabulary and theological claims are essential markers of how the author intends to construct a new identity. Using rhetorical analysis, the dissertation claims that the Prologue …

Cpsf6'S Nuclear Localization Signal Mediates Hiv-1 Intranuclear Events Following Nuclear Import, Nick Rohlfes

Dissertations

The early stages of the HIV-1 lifecycle include the trafficking of the viral capsid into the nucleus of infected cells. The viral capsid, which encloses the viral genome and accessory proteins required for reverse transcription (RT) and integration, traffics towards the nucleus and enters through the nuclear pore complex (NPC). This process is mediated through interactions between the virus and several host proteins, including cleavage and polyadenylation specificity factor 6 (CPSF6). CPSF6 is an early HIV-1 host factor which assists HIV-1 nuclear localization and post-entry integration targeting. CPSF6 contains a function nuclear localization signal (NLS), and as a result, is …

Sales Professional Preservation: Examining The Impact Of Incongruent Ideological Belief Systems On Intentions To Quit Among Sales Professionals, Brian Lee Morgan

Dissertations

Organizations that lead with ideologies of moral tradition, politics, and social economics are playing a losing game. The ideological belief system congruence within the organization between leaders and members creates a better atmosphere with less turnover and better recruitment. Sales professionals want an environment free of ideological incongruence. Without ideological alignment, they will defect from the organization. Leaders are miscalculating the negative impact on members’ intentions to quit when they are faced with leaders acting upon ideology changes that affect the member-customer ecosystem. In addition, leaders should be aware of the personal attributes that can exacerbate turnover and work to …
