Exploring Moral Permissibility Of Nurse Participation In Limited Resuscitation, Felicia Stokes May 2022

Exploring Moral Permissibility Of Nurse Participation In Limited Resuscitation, Felicia Stokes

Electronic Theses and Dissertations

This dissertation offers a novel approach to support nurses when they face conflict between clinicians and families or alternate decision-makers over potentially inappropriate end-of-life goals of care. This dissertation will provide a normative analysis of the moral permissibility of limited resuscitation, with arguments supported by analyses of families’ and nurses’ perspectives and actions in the EoL decision-making process. Limited resuscitation is a cardiopulmonary resuscitation effort where full pharmacologic and mechanical intervention is not used, or the length of the resuscitative effort is shortened. It is typically associated with deception because it is performed without the knowledge of patients and families. …

Steps Toward The Total Synthesis Of The Chrysosporazine Family, Katie Kaczynski May 2022

Steps Toward The Total Synthesis Of The Chrysosporazine Family, Katie Kaczynski

Electronic Theses and Dissertations

Cancer is one of the leading causes of death worldwide, with 19.3 million new cancer cases and 10 million deaths in 2020 alone. In the United States, cancer was the second leading cause of death after heart disease. One of the reasons that cancer is so frequently terminal is that cancerous cells frequently develop multidrug resistance (MDR) to frontline chemotherapeutical treatments, resulting in cancers cannot be treated and are inevitably fatal. This makes the discovery of ways to combat MDR so important in the treatment of cancer. The chrysosporazines are a family of recently discovered (2019) natural products that have …

A Review Of Current Methods In Avian Dietary Analysis And Their Integrated Application To Characterize The Trophic Niche Of Louisiana Waterthrush (Parkesia Motacilla)., Brandon Hoenig May 2022

A Review Of Current Methods In Avian Dietary Analysis And Their Integrated Application To Characterize The Trophic Niche Of Louisiana Waterthrush (Parkesia Motacilla)., Brandon Hoenig

Electronic Theses and Dissertations

Characterizing a species’ dietary composition presents an avenue to understand many facets of its ecological niche and can provide essential information for the species’ long-term conservation. To date, the vast majority of diet studies have relied on direct identification of prey during foraging observations or from diet samples to characterize the dietary habits of birds. However, advancements in laboratory-based approaches have revolutionized the field of trophic ecology by allowing researchers to indirectly infer dietary habits with higher resolution across greater time scales. Here, I apply two of these laboratory-based techniques, namely DNA metabarcoding and stable isotope analysis, to characterize the …

Richard Sennett Calling In Communication Ethics, Lin Gu May 2022

Richard Sennett Calling In Communication Ethics, Lin Gu

Electronic Theses and Dissertations

This project focuses on an interplay between Richard Sennett’s scholarship and the literature of communication ethics. Content from communication ethics provides a better understanding on how Sennett contributes to urban communication in this historical moment, and answers how we can make communication possible in the era of difference.

Sennett’s scholarly concerns starts with a phenomenon that he termed as the fall of public man, which is people’s self-withdrawal from the public domain. Sennett initially credited this to a mismatched “I” and “me” and believes reconciling them would solve the problem. Later, Sennett realizes the self-withdrawal from the public domain has …

Exploring The Phenomena Of Faculty Who Utilize Contemplative Pedagogy In The Helping Professions, Christina Frasher May 2022

Exploring The Phenomena Of Faculty Who Utilize Contemplative Pedagogy In The Helping Professions, Christina Frasher

Electronic Theses and Dissertations

The phenomenon of faculty who utilize contemplative pedagogy in the helping professions is a topic rarely discussed in the literature. In my review of the literature, I have found only one dissertation on faculty perspectives, one dissertation on individuals in higher education, and one study that used the perspective of faculty as the primary data. While this information is valuable, it is not context-specific research on how faculty in the helping professions experience practicing contemplative pedagogy. At present, there are no studies that explore how faculty process and utilize contemplative pedagogy when teaching in the helping profession; this study contributes …


Investigating The Effect Of Dissolved Oxygen-Assisted Corneal Cross-Linking (Cxl) On Porcine Corneas, Julianni Dar May 2022

Investigating The Effect Of Dissolved Oxygen-Assisted Corneal Cross-Linking (Cxl) On Porcine Corneas, Julianni Dar

Electronic Theses and Dissertations

Corneal cross-linking is a clinical procedure that is known to stop the progression of keratoconus, an eye disease that affects the cornea’s structure, ultimately leading to vision loss in its advanced stages. The typical treatment plan includes riboflavin and UV-A exposure in the hope to increase the mechanical properties of the cornea. There are two types of CXL pathways, with Type-II CXL requiring oxygen. Naturally, the dissolved oxygen is limited in the cornea; therefore, limiting the effect of Type-II CXL. This study proposes to improve the Type-II CXL contribution by integrating dissolved oxygen during the standard CXL treatment used in …


Stanley Hauerwas' Approach To Christian Marital And Sex Ethics: A Review And Speculative Expansion, Jeffrey A. Schooley May 2022

Stanley Hauerwas' Approach To Christian Marital And Sex Ethics: A Review And Speculative Expansion, Jeffrey A. Schooley

Electronic Theses and Dissertations

Few places in congregational and denominational life are more fraught with tension and division than conversations about marital and sex ethics. Systemic abuses mingled together with individual failures on this issue has led to confusion, conflict, and chaos. Worse yet, the remedies proposed—and they are many—tend to either double down on “Traditional” values or seek massive reformation of Christian convictions in light of Modern philosophical, anthropological, and sociological presuppositions. Interlocutors quickly come to an impasse and fragmentation occurs. The catalyst for these conflicts is often debates over same-sex marriage, but one does not have to wade far into this conversation …

A Life Lived With Schizophrenia: When Mother’S Love Is Kept In The Dark Exploring Maternal Communication And Attachment Organization In Families With Schizophrenia, Myrsini Stefanidou Marini May 2022

A Life Lived With Schizophrenia: When Mother’S Love Is Kept In The Dark Exploring Maternal Communication And Attachment Organization In Families With Schizophrenia, Myrsini Stefanidou Marini

Electronic Theses and Dissertations

In recent years, research into the transgenerational transmission of attachment styles has shown that a mother’sattachment style often predicts the attachment style of her infant. Fearsome parental behavior has been found to predict disorganized attachment in infants, which is further associated with a range of mental health disturbances in adolescence. Furthermore, regular patterns of disturbed communication between mother and child have also been found to lead to ‘schizophrenic’ thinking and behavior in the child’s life. While acknowledging that genetic and other biological factors contribute to the emergence of schizophrenia, this study focused on disorganized attachment and disturbed communication between mother …

The controversy surrounding Osaka and others led to further questions. Looking through the lens of agenda setting and framing theories, the purpose of this study is to better understand the frequency, variety, and evolution of language in journalistic coverage of …


Cultural Trauma Fiction: Political Violence, Rampage Violence, And Structural Violence In Contemporary American Literature, Courtney Mullis May 2022

Cultural Trauma Fiction: Political Violence, Rampage Violence, And Structural Violence In Contemporary American Literature, Courtney Mullis

Electronic Theses and Dissertations

This dissertation identifies and proposes a new subgenre of American literature, Cultural Trauma Fiction, that has arisen since the late 20th century in response to numerous large-scale traumatic events and their representation in the media. Cultural trauma occurs when a shocking, shared event fractures collective identity and initiates a discursive process to understand what took place, why it happened, and how the affected culture can heal. Cultural traumas differ from individual trauma because cultural traumas affect a culture, rather than an individual, and because they are mediated; many members of the culture experience the trauma of these events secondhand …

A Microfluidic Assay For Single Cell Bacterial Adhesion Studies Under Shear Stress, Amanda Trusiak May 2022

A Microfluidic Assay For Single Cell Bacterial Adhesion Studies Under Shear Stress, Amanda Trusiak

Electronic Theses and Dissertations

The study of bacterial adhesion to host cells is important in understanding bacterial pathogenesis and developing new therapeutic approaches. Here, we studied bacterial adhesion under shear stress using a novel microfluidic method. Specifically, the adhesion of a uropathogenic E. coli strain (FimHOn, ATCC 700928/CFT073) to mannose-modified substrates was studied under flow conditions. The FimHOn E. coli strain expresses FimH which is a mannose-specific adhesin found on the fimbriae that binds to glycoproteins on the epithelium. We developed a microfluidic method that mimics bacterial adhesion to urothelial cells. First, the microfluidic channels were modified by sequentially adsorbing BSA-mannose and BSA onto …
