Application Of Immobilized Palladium Monolithic Catalysts In Suzuki-Miyaura And Tsuji-Wacker Redox Reactions, Sajjad Ghobadi

Theses and Dissertations

Herein, a wholistic analysis of the viability of monolithic catalysts for redox reactions is presented. The interdisciplinary approach taken in this systematic study included preparation and investigation on Pd-on-carbon monoliths as catalysts in a flow and electrochemical settings.

The Suzuki-Miyaura reaction-focused study led to rational design, preparation, and successful application of Pd⁰-on-graphene oxide (GO) monolithic catalysts in flow conditions. In this study a combination of chemical reduction, freeze-casting, and vapor-phase reduction processes was applied to Pd-GO structures leading to the preparation of these monoliths. The Suzuki flow synthesis reactions revealed that the monolithic structure led to significantly improved …

Anticholinergic Burden And Risk Of Cognitive Impairment In Older Adults, Syeda Hashimi

Theses and Dissertations

Studies reveal that 10-27% of older adults chronically use anticholinergic medications. Increased cumulative anticholinergic burden scores are associated with increased risks of dementia. The mechanisms by which anticholinergic drugs negatively impact cognition remain elusive. However, researchers speculate that the drug’s impairment of cholinergic neurons promotes neuroinflammation.

We hypothesize that drugs with anticholinergic properties will induce inflammation in the brain. MCP1 and IL 6 are chemokines that contribute to neuroinflammation. We investigated the influence of diphenhydramine (Benadryl) on the production of MCP1 and IL-6 in Normal Human Astrocytes and Paroxetine on the production of MCP1 in Normal Human Astrocytes and Normal …

An Intuitive Eating Intervention For College Women With Disordered Eating: Evaluating Two Accessible And Affordable Approaches, Carolyn B. Burnette

Theses and Dissertations

Undergraduate women of all racial and ethnic groups engage in disordered eating behaviors (DEBs) at alarming rates. Most women do not receive treatment, with the largest disparities observed in women of color and those at higher weights. Prevailing interventions have limitations that could exacerbate these disparities, such as an emphasis on the thin ideal, which is often considered less relevant for some women of color. This is concerning, as disordered eating is often chronic and symptom crossover is common. Thus, a transdiagnostic, inclusive secondary prevention approach could enhance outcomes by addressing the spectrum of DEBs in diverse women. The purpose …

Don’T Call This World Adorable & Other Salvaged Stories, Brooke A. Hofsess

Journal of Social Theory in Art Education

In this contribution to the special issue on Precarity, the author builds salvaged stories that touch ecological precarities related to place-based discourses within art education. Tsing’s (2015) attentiveness to precarity and Alaimo’s (2012; 2016) suspicion of sustainability cascade upon the author’s thinking/living/writing with Ecologies of Girlhood, an interdisciplinary, intersectional, intergenerational arts program considering living feminist lives co-creatively with place (Ahmed, 2017). New material feminism moves alongside an Indigenous ontology of land-based pedagogies creating “inter-theoretic conversations” (Rosiek, Snyder, & Pratt, 2019) about sustainability and place. These accounts are simply told and cultivated from everyday practices that explore a craftsmanship of attention …

Cissexism And Precarity Perform Trans Subjectivities, Kevin Jenkins

Journal of Social Theory in Art Education

Precarity is not experienced by all. Rather, as Judith Butler (2009) notes, it is the extreme state of precariousness—a heightened exposure to institutional and social violence imposed on marginalized populations such as people of color, non-white immigrants, people of non-Christian faiths, and LGBTQ+ people. Nor does precarity impact the people in these groups evenly.

The three digital artworks in this series highlight some of the ways in which trans people navigate precarity and are performed by it. The lifetime suicide attempt rate for trans and gender non-conforming people averages at 41% with the highest rate at 46% reported by trans …

Victim Silencing, Sexual Violence Culture, Social Healing: Inherited Collective Trauma Of World War Ii South Korean Military “Comfort Women”, Mijin Cho

AUCTUS: The Journal of Undergraduate Research and Creative Scholarship

The unresolved reconciliation process for WWII South Korean military “comfort women” presents a case of nationally inherited collective trauma, in which South Koreans far removed in time and space from the historical tragedy feel its implications and obligations for reparations and social healing. In examining the South Korean comfort women redress movement and systemic concealment of WWII military sexual slavery, this study investigates a pattern of victim silencing, characterized by institutional patriarchy and ineffective government involvement, from 1945 to 2019. Following the South Korean government’s formal rejection of the 2015 agreement with Japan regarding a final and irreversible conclusion to …

Stigma, Confinement, And Silence : On The Precarious Life And Death Of John Derby, Kevin Tavin, Mira Kallio-Tavin

Journal of Social Theory in Art Education

In this commentary, we take seriously the question of what does it mean to be in a precarious position and a precarious subject within educational institutions. Structured around three concepts, Stigma, Confinement, andSilence we discuss the life and death of art education scholar and colleague, John Derby. We attempt to address how John’s scholarship helped other researchers in art education orientate themselves and take a critical stance based on disability studies.

Investigating Equity Practices And Teaching For Global Readiness In A K-12 School District, Jamie M. Schlais Dr.

Theses and Dissertations

This study investigated K-12 educators’ (N=154) teaching for global readiness practices; perceptions of individual global competencies; and supports needed to provide all students an equitable education. A fully mixed, concurrent triangulation, equal status design, combined Vessa’s (2016) Teaching for Global Readiness Scale (TfGRS) and McCain et al.’s (2014) Globally Competent Learning Continuum (GCLC) to examine educators’ perceptions of teaching for global readiness. Perceptions of district equity initiatives were obtained through teacher interviews and central office administrator questionnaires. Survey results for the second semester of the 2018 school year reported teachers engaged in critical literacy and transactional practices from “never” to …

Synthesis And The Genetic Encoding Of Novel Lysine Post-Translational Modifications, Sahan A. Galbada Liyanage

Theses and Dissertations

Post-translational modifications (PTMs) play a significant role in regulating cell signaling and regulating the inner cellular environment. The study of PTMs and their primary biological functions is critical for the development of new medicines targeting the pathways and biomolecules responsible for the PTMs.

Previous studies revealed the direct coupling of the β -hydroxybutyryl lysine (K_BHB) modification with the gene expression. K_BHB in histone proteins links metabolism to epigenetics and gene expression and enables to study in-depth, how cell metabolism controls the gene expression and vice versa. Similar novel histone modification, K_Lac, attracts a special interest …

Environmental Governance For Whom? Examining The Political, Institutional, Fiscal, And Legal Determinants Of State Environmental Agency Budget Policy In The Us, Andrew R. Duggan

Theses and Dissertations

Budgets are a prospective tool of governance, and appropriations are a planning vehicle reflecting: bureaucracies’ values, complex interactions, collective preferences, political influences, and available resources. Research spanning 30 years finds that environmental pollution is a key determinant of environmental budgets in the US, though myriad factors, actors, and subsystems are important to consider. Due to federalism and devolution of responsibilities and authorities, environmental governance falls largely to the states. While the dynamics that shape state environmental budget policy have received scholarly interest, theoretically-driven examinations of environmental appropriations remain limited within the public budgeting and environmental policy literature.

Behavior Change Techniques To Promote Smoking Cessation During Pregnancy: A Theory-Based Meta-Analysis, Caroline A. Orr

Theses and Dissertations

Despite significant progress, smoking during pregnancy remains one of the leading preventable causes of adverse fetal and maternal health outcomes. Using the current best practice standard of psychosocial counseling, only about one out of every 20 pregnant women quits smoking, and relapse rates are very high. Developing more effective interventions to promote smoking cessation during pregnancy is a critical public health priority that requires a thorough understanding of behavior change and its complex pathways and determinants. As such, the purpose of this three-part study was to conduct the first systematic theory-based evidence synthesis of smoking cessation interventions during pregnancy, and …

Effects Of Violent And Nonviolent Life Stressors Among Urban Early Adolescents: Testing Competing Models Of Comorbid Distress And Externalizing Symptoms, Erin Thompson

Theses and Dissertations

The strong association between stressful life events and the wide-ranging spectrum of psychopathology has led some to advocate for the reconceptualization of traumatic stress. There has been a longstanding debate on whether these symptoms are best represented by using dimensional versus categorical approaches. Moreover, further understanding of the risk factors associated with various dimensions or patterns of comorbid emotional and behavioral problems could inform future research and intervention efforts. The current study tested competing variable- and person-centered approaches and examined how stressful life events are associated with different patterns of distress and externalizing symptoms among a predominantly African American and …

Open Ensemble Modeling Of Confined Electrolytes, Serban Zamfir

Theses and Dissertations

The main purpose of my study was to work towards better understanding the behavior of salt solutions in nanoconfinements and its causes. To this end I have developed an in-house C++ code that can perform notoriously challenging open ensemble Monte Carlo molecular simulations, calculate relevant thermodynamic and extract structural information about each system. I use this code in my first project which deals with the intrusion/extrusion of aqueous NaCl into a nanopore open to a pressurized bulk environment. For my second project, I study the effect of explicitly accounting for intramolecular polarization and accompanying multi-body interactions on the uptake, structure, …

College Students’ Perceptions Of Popular Diets And Orthorexia Nervosa, Madison W. Weinstock

Theses and Dissertations

Data suggest that individuals’ purported dietary patterns influence others’ perceptions of them. However, few studies have investigated how adherence to specific popular diets might influence these perceptions. This study investigated female undergraduates’ (n = 463) perceptions of vignette characters described as adhering to specific dietary practices perceptions of a vignette character in a sample of 463 female undergraduates. Characters described as adhering to a Clean Eating diet were viewed most positively, followed by individuals on the Ketogenic diet or nondieters. Characters following an Intermittent Fasting diet, and those with Orthorexia Nervosa were viewed most negatively. These findings support the …

Plant-Pollinator Associations In An Eastern Serpentine Savannah And The Effects Of Overbrowsing, Allyson Richins

Theses and Dissertations

Chapter 1: Native plant response to deer overbrowsing in a serpentine savannah

Plants are particularly vulnerable to physical disturbance in low productivity areas, due to a high cost of replacing lost plant tissue. In the eastern United States, serpentine grasslands are fragmented ecosystems with high concentrations of rare endemic plant species, low concentrations of soil nutrients, and uncontrolled deer overpopulation. This study assessed functional responses of native angiosperms in a rare eastern serpentine savannah to selective deer browsing. Plant count, flower count, floral area, vegetative area, and plant height of 10 serpentine plant species were compared inside and outside of …

Kcc2: A Novel Therapeutic Target To Rescue Gabaergic Dysfunction And Behavioral Deficits Induced By Hiv And Opiate Use, Aaron J. Barbour

Theses and Dissertations

With adherence to combined antiretroviral therapy (cART), HIV infection can be considered a controllable chronic condition, but quality of life issues remain. The preeminent of which, HIV-associated neurocognitive disorders (HAND), encompasses an array of neurological complications and has persisted despite cART implementation. The symptoms of HAND can be exacerbated by opiate use, a common comorbidity for people infected with HIV (PWH). While neurons are not infected by HIV, they incur sublethal damage, with γ-amino butyric acid- (GABA)ergic function being particularly vulnerable to viral and inflammatory factors released by infected/affected glia. This dissertation presents studies on novel organoid and dissociated primary …
