Railspace: A Geocritical Study Of The Railroad Through American Literature And Culture, Michael A. Smith

Electronic Theses and Dissertations

This dissertation uses geocriticism to argue that the American railroad is best understood as a set of discursively constructed railspaces formed through a variety of viewpoints, a polysensorial awareness of space, and stratified social relationships and power struggles. This study takes up four railspaces, the constituent texts of which demonstrate how intertextual discourse shapes and is shaped by the railroad. The observation car, charted through California Zephyr advertisements and Muriel Rukeyser’s “Campaign,” is an apparatus that produces perpetual spectacle. Three novels—Sister Carrie by Theodore Dreiser, Double Indemnity by James M. Cain, and Strangers on a Train by Patricia Highsmith—and …

A Catholic Ethic For Smartphones In Tanzania, Faustine Tarimo

Electronic Theses and Dissertations

This project is a synthesis of Church documents and papal encyclicals to form a Catholic ethic for the smartphone use in Tanzania. The research question for this project is how a Catholic communication ethic shapes the use of smartphones for human communication in Tanzania. The problem I want to address is the perceived danger of losing connectivity or ‘real’ face-to-face encounters between people in “let’s talk culture” in Tanzania. The goal of this project is to appreciate the use of smartphones, at the same time to attend to a Catholic ethic to integrate into a “let’s talk culture” some digital …

Pharmacological Characterization Of Novel Serotonin Transporter Inhibitors Identified Through Computational Structure-Based Virtual Screening, Michael Wasko

Electronic Theses and Dissertations

Depression is a mental health disorder affecting greater than 350 million people worldwide with roughly 7% of the United States population diagnosed as of 2017. The selective serotonin reuptake inhibitors (SSRIs) have been the mainstay of pharmacotherapies for depression for the last 40 years. The SSRIs target the serotonin transporter (SERT), a monoamine transporter (MAT) responsible for terminating serotonergic neurotransmission. The SSRIs are not perfect therapeutics and suffer from delayed response times, inconsistent efficacy among patients, and often produce intolerable side effects. Therefore, a strong need exists to develop new antidepressants that are more efficacious and have fewer adverse effects. …

Antiparasitic Peptide From The Ocean: Discovery, Synthesis And Structure-Activity Relationship Study, Kh Tanvir Ahmed

Electronic Theses and Dissertations

Millions of people die every year because of infectious diseases, and malaria is among the top five of the deadliest infectious disease. In 2018, malaria took more than four hundred thousand lives, and more than half of them are children under five years of age. Most malaria-affected parts of the world are also the home of the most underprivileged people. Seemingly, antimalarial drug discovery never achieved the attraction that it requires. Like malaria, another infectious disease that is not extensively explored by drug discovery campaigns is American trypanosomiasis or Chagas disease.

Subjects Of Economy: Social Documentary Poetics And Contemporary Poetry Of Work, Michelle B. Gaffey

Electronic Theses and Dissertations

Although the term “documentary” originated in film and photography studies, it has been used to describe a range of compositional and research strategies in discussions of twentieth and twenty-first century poetry as well. A study of such documentary poetics, however, requires us to distinguish between documentary poetics in general and social documentary poetics in particular. To illustrate this distinction, I discuss five contemporary books of poetry and photographs: C.D. Wright’s and Deborah Luster’s One Big Self: Prisoners of Louisiana, Cynthia Hogue’s and Rebecca Ross’s When the Water Came: Evacuees of Hurricane Katrina, Chris Llewellyn’s Fragments from the Fire: …

Effectiveness Of An Interdependent Group Contingency With Randomization Using The Ipad, Chelsea Gyke

Electronic Theses and Dissertations

Classroom management, although considered one of the essentials of the optimal learning experience, is often a challenge for teachers. Certain classroom management strategies, such as group contingency interventions and token economies, are evidence-based strategies to aid teachers in gaining successful management of the classroom. The utilization of Class Dojo, a popular classroom management website, as a mechanism to implement an interdependent group contingency (IGC) intervention with randomized components may increase both the effectiveness of the intervention and the social validity of the intervention when compared to a manual implementation.

Participants included students in an elementary school self-contained special education classroom …

“That Those Hearing Or Reading Might Strive To Imitate”: Donative Intent, Positive Triangular Mimetic Desire, And The Portrayal Of The Mediator-Divine (Non)Object Relationship In Richard Rolle, Julian Of Norwich, And Richard Crashaw, Steven Geitgey

Electronic Theses and Dissertations

Mystical texts often present themselves as possessing a “donative” intent, in which the writer aims to share the significance of their own experience. This dissertation will show how a consideration of donative intent and its textual results can enrich the study of medieval and early-modern mystical writings, approaching them from the broad concept of triangular mimetic desire in conjunction with other theoretical insights in order to examine the methods through which writers seek to portray their mediator-object relationship with God and inspire reading subjects’ mimetic desire.

I will elucidate Richard Rolle’s portrayal of his mediatorial purpose and unique experiences, and …

Melatonin-Tamoxifen Drug Conjugates As Breast Cancer Drugs: Pharmacological Evaluation In Phenotypically Diverse Breast Cancer Models And Pharmacokinetic Assessment In Liver Microsome And Female Mouse Models, Mahmud Hasan

Electronic Theses and Dissertations

Tamoxifen is a first-generation selective estrogen receptor modulator, which reduces the risk of both invasive and non-invasive breast cancer (BC) as well as tumor recurrence in several clinical trials. However, chronic use of tamoxifen can increase uterine cancer risk and induce tamoxifen resistance. In past studies, melatonin alone reversed tamoxifen resistance induced by light exposure at night in rodents. This study demonstrates that melatonin or melatonin-based ligands (e.g., melatonin-tamoxifen drug conjugates) may be novel BC therapies that are efficacious and free of side effects. To investigate this further, five melatonin-tamoxifen drug conjugates with different linker sizes were synthesized and screened …

Accurate Quantitation Of Hexavalent Chromium For Reference Standard Certification And Quality Control Testing Using Speciated Isotope Dilution Mass Spectrometry, James E. Henderson

Electronic Theses and Dissertations

The ability to perform accurate, repeatable, and defensible elemental and molecular speciated analysis is immensely significant for measurements that support human health, environmental science, and industry. This is especially true since trivalent chromium [Cr(III)] is necessary for proper nutrition, while hexavalent chromium [Cr(VI)] is extremely toxic, genotoxic, and carcinogenic. The main challenges associated with speciated analysis are related to reactive species that are continuously transformed or converted to other species during sample processing. Accurate determination of Cr(III) and Cr(VI) species require a method that is capable of monitoring and correcting for interconversion, bias, and instrumental error. Traditional quantitative methods, such …

The Haven: A Clinical Ethnography Of A Farm-Based Therapeutic Community, Monica Lawson

Electronic Theses and Dissertations

Therapeutic communities are communal spaces where individuals live for an extended period in hopes of recovering from personal crises, or while coping with severe mental illness. They provide a humanistic alternative to inpatient hospitalization. Although they are seldom studied, even less is known about farm-based therapeutic communities in the United States, where communal work is viewed as central to recovery. This dissertation examines the experience of living and working at the Haven. Originally conceived as a farm-based community where suffering individuals could experience reprieve from the demands of the “working world,” and heal by living in community, recent changes in …

Atom Transfer Radical Processes: From Catalyst Design To Polymer Synthesis, Characterization, And Application, Michael Novak

Fluoride Removal With Augmented Bentonite In Drinking Water And Community Perceptions In Arusha, Tanzania, Kara Okular

Electronic Theses and Dissertations

High fluoride concentrations in drinking water affect millions of people around the world. The World Health Organization recommended a fluoride concentration in drinking water of ≤ 1.5 mg/L; fluoride above this concentration can cause long-term dental and skeletal fluorosis. Fluoride imparts no taste to water; therefore, people do not realize that they are ingesting high fluoridated water. Researchers sought to develop a material to remove fluoride from drinking water through sorption. Aluminum was used to form a double ionic layer on the bentonite clay surface. Once mixed in contaminated water, a coagulant, ferric sulfate, was used to separate the bentonite …

Examining The Intersectionality Of Religious Faith, Spirituality, And Healthcare Communication, Felix Okeke

Electronic Theses and Dissertations

This dissertation is my own contribution in responding to the concern raised by certain communication scholars. Their concern was that little research and few publications have been done in the communication field by communication scholars that trace the relationship among religious faith, spirituality, and healthcare communication. While Parrott (2004) describes this apparent neglect as “collective amnesia,” others label it “religion blindness.” Thus, in trying to trace this relationship, this project uses Christian, biblical, and bioethics backgrounds to establish the value, sacredness, and dignity of human life, since these concepts make healthcare and healthcare communication necessary in the first place. These …

Control Of Corrosion On Ss316l Using Surface Initiated Polymers, Alexander Rupprecht

Electronic Theses and Dissertations

Pitting corrosion is arguably one of the most destructive and dangerous forms of corrosion, resulting in damage to structures, the environment, and public health. In addition, damage caused to structures such as bridges, pipelines, and boats, corrosion also has a profound effect on the biomedical community. Implanted metallic devices (i.e., vascular stents and artificial joints) are prone to pitting corrosion caused by aggressive ions present in extracellular fluid. To provide a corrosion-resistant surface on SS316L, films of poly(styrene), poly(methyl acrylate), and poly(methyl methacrylate) were formed using surface-initiated atom transfer radical polymerization (SI-ATRP). The resulting hydrophobic polymer films had a fractional …

Identifying The Effects Naturally Forming Bacterial Communities Have On The Efficiency Of Passive Remediation Systems Built To Treat Abandoned Coal Mine Drainage, Michelle M. Valkanas

Electronic Theses and Dissertations

Abandoned mine drainage (AMD) has resulted in worldwide devastation. Passive remediation systems (PRS) are a cost-effective option to treat AMD. While the geochemistry (abiotic) of these systems is well understood, little work has been done to characterize the microbial communities (biotic) that naturally form within these systems. The goal of this dissertation was to identify the effects that bacterial communities have on the efficiency of PRSs. Four passive remediation sites built to treat coal mine drainage were studied: two that treat acidic discharges (Boyce and Middle Branch) and two that treat circumneutral discharges (Wingfield Pines and Lowber). Survey studies suggested …

Rna Structure And Function: Biological Relevance In Neurodegenerative And Infectious Disease Pathogenesis, Joshua Imperatore

Electronic Theses and Dissertations

The studies outlined in this dissertation encompass a broad focus, relating to the pathogenesis of neurological disorders such as Alzheimer’s disease, fragile X syndrome, and amyotrophic lateral sclerosis, as well as a novel infectious disease, COVID-19. However, all four studies detailed within this dissertation contain similar elements, namely, the coordinated role of RNA structure and function in essential molecular mechanisms. The results of these investigations allow us to speculate on various disease- related mechanisms, including dysregulated microRNA processing pathways, nucleocytoplasmic shuttling via distinct RNA-protein interactions, and fine-tuned molecular switches controlling genomic dimerization and viral hijacking of host cellular microRNAs. Taken …

Epidemics, Politics And Public Health: Ludwig Rajchman, Md, The League Of Nations Health Organization And The Creation Of A Transnational Health Institution, Paul J. Weinbaum

Electronic Theses and Dissertations

Traditional scholarship on the League of Nations labels the organization as a failure because it did not prevent the outbreak of the World War II. Recent research examines League activities in a more comprehensive manner and concludes that the organization should be credited with important and enduring achievements. Perhaps the most successful work was carried out by the Health Section led by Dr. Ludwick Rajchman. Using primary sources from the League archives in Geneva, documents from organizations such as the Rockefeller Foundation, articles from medical journals and other relevant secondary sources, I argue that the Health Section, became the world’s …
