Relations And Folds In Leibniz: Monadological Intimacy, Jeff Lambert

Electronic Theses and Dissertations

My goal is to provide a clear explanation of Leibniz’s notoriously difficult system of relations. Relations among ‘windowless’ substances that exert no causal power over one another seems like a pipe dream that should be abandoned. However, I demonstrate that each substance expresses its relations only through the unique representation of all other substances. That is, any relation a substance expresses is due to this unique, perspectival, non-causal, representation of others. Because this is the case for all substances, this means that this relation of representation is an ongoing process of interconnection for all substances. This representation is not merely …

Agency, Identity, And Authority In Rwanda: 1950s Political Rhetoric As A Bridge To Post-Colonial Genocide, Amanda E. Rollinson

Electronic Theses and Dissertations

During the Rwandan genocide, Hutu targeted Tutsi and allies. Interpreting this complex event requires examining the late 1950s. Analyzing Tutsi and Hutu in central Rwanda in 1957 improves understanding of political and social context preceding the genocide. This study rejects that the genocide occurred as an inevitable event. Instead, it layers domestic actors with international groups: the White Fathers missionaries; the United Nations; Belgium; and the United States. Analyzing each group and synthesizing their interactions elevates Rwanda’s history from the falsehood of ancient adversaries to a complex, modern narrative. Studying Rwandan rhetoric and responses to it provides an opportunity to …

British Eugenics Failure And Success, Angela Gallagher

Electronic Theses and Dissertations

The historical narrative of eugenics often focuses on those eugenic societies and movements that ‘succeeded’ in part or in full in achieving a eugenic society. Less studied are those societies that failed, whether due to social backlash or internal incoherence. The British Eugenic Educational Society as the foundational point of eugenics, has therefore been overlooked as a result of it’s perceived lack of contribution to eugenic thought and its failure to pass eugenic legislation. Founded by Francis Galton, the originator of the philosophy of eugenics, the British Eugenic Educational Society should have been successful given it’s reputation and the numerous …

Friendship In The Digital Age: Implications From A Philosophy Of Communication Approach, Tiffany Petricini

Electronic Theses and Dissertations

Friendship is a central relationship-style that grounds us. Much of the literature on the effects of technology on our relationships, especially friendship, has taken a skeptical approach. The notion of friendship is historically-situated, thus, it requires attention in each era and has prompted questions throughout human history. Our time is no exception. Changing cultures and redefinitions of basic human institutions have led us to our current moment, in which we are experiencing a loud and continuing debate on the effect of technology on our lives. Advancements in science have allowed us to understand our past and present in new ways. …

The Appearance Of The Other Ego In Edmund Husserl’S Phenomenology, Paul Zipfel

Electronic Theses and Dissertations

In this work I investigate Edmund Husserl’s phenomenological analyses of the appearance of the other ego in order to elucidate the essential components of the sense of the other ego: co-constitution, inaccessibility, and a unique process of verification. I open with an example illustrating the way in which other egos appear to me as different from ordinary objects in the world. When one looks outside in a storm and sees a branch rapping on the window, it is not an alarming experience. However, were another person to be rapping at the window, the experience would be quite different. This is …

Cultural Identity Salience, Individuation, And Life Satisfaction In Emerging Adulthood, Matthew L. Nice

Electronic Theses and Dissertations

This quantitative study examined emerging adults’ (18-29 years old) cultural identity domains of race/ethnicity identity, gender identity, sexual identity, spiritual identity, and socioeconomic class identity with their features of individuation from parents and life satisfaction. Additional emphases were placed on understanding the differences between college-going and non-college-going emerging adults and the differences between early (18-23 years old) and later (24-29 years old) emerging adulthood. This study supported both significant and non-significant relationships among the cultural identity domains salience with the features of individuation and life satisfaction. Emerging adults who attend college were revealed to have higher life satisfaction than those …

Caring For Victims Of Child Maltreatment: Pediatric Nurses’ Moral Distress And Burnout, Angela Karakachian

Electronic Theses and Dissertations

Background: Moral distress is a significant concern for nurses as it can lead to burnout and intentions to leaving the profession. Pediatric nurses encounter stressful and ethically challenging situations when they care for victims of suspected child maltreatment. Data on pediatric nurses’ moral distress in this situation are lacking, as most research in this field has been done in adult inpatient and intensive care units.

Aims: The purpose of this study was to describe pediatric nurses’ moral distress and determine the impact of caring for victims of suspected child maltreatment on nurses’ moral distress, burnout, and intention to leave.

The Performer As Analyst In The Piano Sonata Opus 12 By Jean Sibelius, Jesse Tingle

Electronic Theses and Dissertations

This thesis examines and models the process of analysis as a means for performers, particularly pianists, to engage with the large-scale organizational features of musical works, using the Piano Sonata, Opus 12 by Jean Sibelius as a case study. The unique character and structure of each of the three movements suggests an equally wide range of approaches to analysis, including studies in sonata form, construction of a musical narrative based on external source material, and the use of concepts from Sonata Theory to explain the logic of a highly unconventional tonal and thematic design. The analyses are interwoven with a …

An Investigation Of Technology Implementation Through The Lens Of Student Centered Learning And The Technological Pedagogical Content Knowledge Paradigm, Adam Wasilko

Electronic Theses and Dissertations

National statistics show that there are increases in access and availability of computers, and technology, in both the classroom and students’ personal lives (Culp et al. 2005, Hoffman & Ramirez, 2018). However, Tas (2017) and Wachira and Kenngwee (2010) posit that there is stagnation, even declines in certain cases, of the integration of instructional technologies in delivering student center learning in the classroom. This decline is even more prevalent in the science classroom (Vickrey, Golick, & Stains, 2018). Teachers face many challenges in the classroom; especially when technology integration is considered (Blackburn, 2016). This study seeks to determine which conditions …

The In/Authentic Subject: Kierkegaard, Heidegger, And Selfhood, Joseph Tighe

Electronic Theses and Dissertations

This dissertation represents an attempt to understand the self, what it is, what it means, and how it provides subjective identity. These concerns are situated within a personal narrative that describes the loss of self and its rediscovery subsequent to that loss. In critically examining the work of both Soren Kierkegaard and Martin Heidegger on the concept of authenticity, I have attempted to come to terms with my experience of the loss of selfhood as well as the conditions of possibility for its return. I argue that Kierkegaard’s construction of the self, while problematically religious, convincingly describes the experience of …

The Problem Of Nature In The Phenomenology Of Merleau-Ponty, Alessio Rotundo

Electronic Theses and Dissertations

In my dissertation, I show that Merleau-Ponty’s idea of nature yields a double meaning: nature as ensemble of genetic and productive processes that are attainable in experience (phenomenal nature) and nature as that which enables this experience (transcendental nature). My thesis is that the two meanings of nature, when taken together, offer a guide to Merleau-Ponty’s final philosophical formulations about “flesh” and the “visible” and the “invisible.” The aim of the dissertation is to trace the salient conceptual and methodological complications entailed by this conception. I argue that the bivalence of the problem of nature in Merleau-Ponty receives a methodological …

St. Ignatius' Quill Pen: Exploring The Orality-Literacy Difficulty In The Spiritual Exercises, Hongchao Qian

Electronic Theses and Dissertations

Informed by the work of Walter Ong, in the first prelude of the First Week in the Spiritual Exercises, St. Ignatius of Loyola used an emblematical image, the “prison-cage”, to provide phenomenological accounts for the exercitants to examine the existential situation within. This dissertation explores into the difficulty of being rhetorical in mediating on the existential situation emblematically. I try to understand the orality-literacy dynamic within the Exercises through the theoretical framework of semiotic phenomenology. The Ignatian emblematics can be understood as phenomenological descriptions that asked the exercitants to provide the parts of moral-phenomenological reductions and phenomenological interpretations within …

The Physiology And Evolution Of Selenite Respiration In Bacteria, Michael Wells

Electronic Theses and Dissertations

The selenium oxyanions selenate (Se(VI)) and selenite (Se(IV)) can be utilized by some bacteria and archaea as terminal electron acceptors in anaerobic respiration. Se(VI) and Se(IV) respiration is mediated by a phylogenetically and ecologically diverse array of organisms, suggesting that selenium respiration is ubiquitous in natural environments. Several respiratory Se(VI) reductases have been characterized in bacteria, revealing that Se(VI) respiration has evolved independently several times in this domain. Se(IV) respiration, in contrast, has yet to be characterized. I have purified and characterized the first respiratory Se(IV) reductase from Bacillus selenitireducens MLS10. The Se(IV) reductase appeared to purify as a single …

The development of mobile communication occurred during the second half of the twentieth century and has become domesticated into everyday life. One consequence of the widespread adoption of mobile communication device use is an increase in connectivity. This increase in connection has led to a shift in interpersonal relationships. People now must be aware of when to connect and disconnect to develop meaningful relationships in private, public, and social realms. This project seeks an understanding of how the consequence of increased connectivity and the development of …

Gene Delivery To The Blood-Brain Barrier For Ischemic Stroke Therapy, Wanzhu Zhao

Electronic Theses and Dissertations

Stroke is a major cause of death in the United States. We aim to develop safe and efficient approaches for the treatment of stroke. Regenerative therapies have been identified as the major need for curing stroke [1]. We explored two different carriers (poly (ethylene glycol)_5k-poly (L-aspartate-diethylenetriamine)₄₈ (PEG-DET) / Pluronic P84 (P84) and exosomes (EXOs) / microvesicles (MVs)) to deliver brain-derived neurotrophic factor (BDNF) plasmid DNA (pDNA), a functional gene encoding a neurotrophin. In the first project, our data showed that DNA nanoparticles (NPs) with 0.03% P84 was a promising formulation to deliver Luciferase pDNA into immortalized human …

Characterization Of Photoacoustic Flow Cytometry Signals, Craig Benzinger

Electronic Theses and Dissertations

Photoacoustic flow cytometry has been utilized to clinically determine the presence of melanoma circulating tumor cells (CTCs). Further investigation was conducted into the morphology of detection signals and how they could be manipulated to allow for further classification. Novel features were extracted from waveforms that appear to have strong classification ability. Neural networks were also used to determine classification potential and the creation of feature mapping for future unsupervised classification. Detections were expanded from single waves to a time dependent multiwave event. Waveforms were also determined to be of non-parametric distribution, allowing for classification by neural network but not allowing …

With this emergence of a larger Biracial community, schools need to consider how they will implement equitable resources and practices to meet the needs for this unique population. School librarians, serving as instructional leaders, can provide the necessary materials and strategies to support their students who are Biracial in order to foster positive racial identity. The purpose of this study is to explore school librarians’ perspectives on the influence of multicultural literature on students’ acceptance and understanding …

Pierre Hadot's Holistic Philosophy Of Communication, Jonathan Crist

Electronic Theses and Dissertations

Pierre Hadot’s holistic philosophy of communication attends to the health of the self and community through practice of spiritual exercises for the transformation of one’s entire being, working at the nexus of mind, body, soul, and cosmos. The task is ever-incomplete, works in an understanding of “human being as essentially an exposure that lacks a closed identity” and “keep[s] sight of the opening, wound, or lack that remains at the heart of any community and all communication” (Butchart 136). This is responsive to the present moment experiencing disjointed experience of time and space, increased anxiety, underdeveloped capacity for attention, and …

A Genomic Analysis Of Bobcat Populations In North America With A Comparison To The Canada Lynx: An Assessment Of Local Adaptation To Unique Ecoregions And Phylogeography, Jennifer C. Broderick

Electronic Theses and Dissertations

Bobcats (Lynx rufus) are an ecologically and genetically diverse species with a large contiguous range throughout North America. The species not only has a wide array of phenotypic variation compared to other mammals, but shows marked adaptability across ecozones with differing ecological influences. It is these various selective pressures in distinctive parts of the continent that have likely led to localized adaptations within the bobcat metapopulations. The species is also marked by its ability to maintain connectivity and populations in anthropogenically developed areas, an advantage it has over other felids, including its close relative the Canada lynx ( …

Pilot Study Exploring The Effect Of Targeted Cox-2 Inhibition In Macrophages Responding To Neuronal Injury; Promoting Enhanced Axonal Regeneration, Alyssa Brauckmann

Electronic Theses and Dissertations

Celecoxib nanoemulsion (CXB-NE) has been developed as a macrophage targeted analgesics by Dr. Janjic and her team at Duquesne University, (Janjic et al, 2018; Liu et al, 2020; Saleem et al, 2019b; Vasudeva et al, 2014). The CXB-NE nanoemulsion carrying a Nonsteroidal Anti-inflammatory (NSAID) inhibitor of COX-2 activity result in a reduction in PGE2 expression in macrophages. Using CXB-NE in rats that have peripheral nerve injury constricting the sciatic nerve relieves hypersensitivity, a pain-like behavior. The treatment also decreases inflammation associated with this chronic constriction injury (Janjic et al, 2018; Saleem et al, 2019b; Stevens et al, 2019). In this …

Identification Of Human Adrenal Carcinoma Cells Using Photoacoustic Flow Cytometry, Alexis Stahl

Electronic Theses and Dissertations

With consistently high mortality rates in patients with adrenal cancer, lack of early detection and diagnosis are an ever increasing problem in fighting the deadly disease. Currently, very few patients are diagnosed with adrenal cancer within the early stages due to the absence of symptoms until large tumors are formed, which is in most cases is fatal. Because of this, early detection equipment is crucial to optimizing the survival rate in patients. We studied the absorbance wavelength of human adrenal carcinoma cells, as well as the minimum cell concentration needed in samples using photoacoustic flow cytometry (PAFC). PAFC generates ultrasonic …

Using Tandem Mass Spectrometry And Irmpd Spectroscopy To Determine The Intrinsic Reactions Of Uranyl-Containing Ions, Irena Tatosian

Electronic Theses and Dissertations

Developing a comprehensive understanding of the intrinsic reactivity of uranium-containing species remains an important goal, as it may influence future developments in areas ranging from new approaches to nuclear fuel processing to studies of the migration and fate of the element in the environment. At a more fundamental level, such studies contribute to the understanding of the role that 5-f electrons may play in chemical bonding, the so called “f-electron challenge”. Electrospray ionization (ESI) is an effective way to generate gas-phase complexes containing uranium and uranyl ions for subsequent studies of intrinsic structure and reactivity. Studies in the gas-phase are …

N-Terminal Imine Derivatization For Enhanced De Novo Peptide Sequencing: A Study Of The Fragmentation Pattern Generated From Cid Of Peptide-Imines, Khiry L. Patterson

Electronic Theses and Dissertations

In this work, the fragmentation pattern derived from model peptides derivatized to create N-terminal imines (Schiff bases) were evaluated. Collision-induced dissociation of the protonated peptide-imines ([M+H]⁺) generally produced complete series of the sequence informative a_n and b_n ions, now undoubtedly characteristic of the peptide ion species. A novel product ion was also observed, denoted the y^ǂ ion, determined by IRMPD spectroscopy and density functional theory to be generated from the elimination of the N-terminal amino acid residue despite the N-terminal modification. It was concluded the pathway involved a nucleophilic attack by an amide nitrogen and …
