Rooted In The Earth: An Igbo Sacramental Nature Of The Universe, A Model For Igbo Christian Ecological Ethics, Kenneth Oguzie

Electronic Theses and Dissertations

The contemporary Igbo society faces a lot of challenges. These include political, religious, and moral crises. These crises affect the environment in many ways. They threaten the peace and harmony of the Igbo society. As a result, it touches on faith. The Igbo society holds a holistic view of life. Whatever affects one aspect of life affects the other areas. Ecologically, various factors are responsible for the crises. These include changes in lifestyle from the traditional way of living to modern style of life with its penchant on consumerism. Also, colonialism and its lingering residues, civil unrests, politics, population growth, …

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 …

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 20^th 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 …

Reporting On Athletes And Mental Health: An Evolution In Language And Lexicon From 1970 To 2019, Vivian Ferris

Electronic Theses and Dissertations

In the spring and summer of 2021, several athletes made headlines for seemingly prioritizing mental health over the status quo of sports society. For example, in May 2021, during the French Open, professional U.S. tennis player Naomi Osaka announced she would not appear at press conferences, despite threats of fines, citing on social media it was for her mental health. 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 …

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 …

A Systems Approach In Clinical, Organizational And Professional Ethics In Healthcare, Dina Siniora

Electronic Theses and Dissertations

This dissertation aims to apply a systems approach to clinical, organizational, and professional ethics in healthcare. A systems approach can offer a valuable understanding of bioethical issues and should be more extensively utilized to advance the bioethical analysis. This research is proposed to inspire systemic thinking as an approach to tackle the issues in clinical, organizational, and professional ethics, given that healthcare ethics can be considered as a kind of systems thinking because it takes into consideration the connections among several systems and comprehends their consequences on one another. Systems thinking has appeared as a means of hypothesizing and tackling …

The Lived Experience Of Second Victim Crnas, Michael Neft

Electronic Theses and Dissertations

A second victim is a health care provider who has been involved in a critical event. A

critical event is a clinical situation in which an unforeseen clinical outcome occurs, or

the clinical deterioration of the patient takes place for many different reasons. The

patient and his/her family are the first victims. The health care provider(s) involved in

the event are second victims. After such an event, the healthcare provider may

experience a constellation of negative emotions, such as guilt, sadness, depression,

somatic symptoms, hypervigilance, and fear. Most second victims require support to

cope with the adverse clinical situation. Second …

Biomaterials: From Scaffold Design To Implant Optimization, Jennifer Marie Armen

Electronic Theses and Dissertations

This work encompasses three individual projects concerning biomaterials and their modifications. Chemically-Induced Cross-Linking of Peptidic Fibrils for Scaffolding Polymeric Particles and Macrophages EAK16-II (EAK) is a self-assembling peptide (SAP) that forms β-sheets and βfibrils through ionic-complementary interactions at physiological ionic strengths. The soft materials can be injected in vivo, creating depots of drugs and cells for rendering pharmacological and biological actions. The scope of the applications of EAK is sought to extend to tissues through which the flow of extracellular fluid tends to be limited. In such anatomical locales the rate and extent of the fibrilization are limited insofar as …

Turbulent Transport Of Dissolved Oxygen In Natural Channels, Alanna Bachtlin

Electronic Theses and Dissertations

The transport and mixing of dissolved oxygen (DO) is important to replenish the oxygen depleted by natural processes; gas transfer in general has implications for ecosystem metabolism and greenhouse gas transfer. Currently, reaeration coefficients can be found through gas tracer methods, which estimates one-way gas transfer. For this project, a net oxygen consumption rate, , was developed using the similarity equations, which provides a value from DO and velocity profiles specific to a stream site. Additionally, three models to calculate friction velocity, which is required for oxygen consumption rate, were compared. Reynolds stresses, mathematically developed in the Reynolds-Averaged Navier-Stokes Equations, …

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 …

A Bioethics Critique Of The Healthcare System In Nigeria: Personal Dignity And Human Solidarity, Cyprian Duru

Electronic Theses and Dissertations

Life is a sacred gift, an indivisible good with an inherent dignity and value. Despite its uniqueness, fragility, vulnerability, and limitations, it remains the most interesting, attractive, and exciting thing one can possess. These attributes invoke a deep sense of respect to life. Recently, science and biotechnology have astonished the world, as they continue to disorient human consciousness on new set of ethical issues. In effect, life is seriously exposed to the perspectives of modern science and technology. Thus, President George W. Bush warns that the powers of science are morally neutral, capable for good and bad purposes. In …

Narrative Authority: A Narrative-Based Multicultural Ethics To Overcome Western Biases In The Current Models Of Care, Fahmida Hossain

Electronic Theses and Dissertations

Technological advances and globalization are transforming healthcare dramatically. But unfortunately, current medical practices remain blind to their multicultural patients’ varied worldviews and norms, especially in the West. As a result, patients often find themselves isolated, anxious, and resentful.

All the humanistic models in the current literature view the individual as a unique and autonomous being and, in turn, provide practices to access and recognize the patient’s personhood. These models—Narrative Medicine, Narrative Ethics, and Ethics of Care—attempt to catch sight of the individual, the person’s situation, and some semblance of the person’s story before diagnosing or offering prescriptions. However, all these …

A Critical Study Of Unaccompanied Homeless Youth In A Local Housing Program, Michael J. Warren

Housing programs available to youth experiencing homelessness offer varying types of supports and initiatives. However, few programs are created by and with the perspectives of these youth. This qualitative study examines the experiences of unaccompanied homeless youth (UHY) while living in a housing program, identifies specific needs of UHY, and aims to learn of the political role the community and educational institutions play in empowering youth experiencing homelessness.

Implications highlight how critical pedagogy can be used by educational leaders to empower student voice and aims to shift student learning from a “banking” model to democratic participation. This research will advance …

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 Contribution Of Ethical Governance Of Artificial Intelligence & Machine Learning In Healthcare, Tina Nguyen

Electronic Theses and Dissertations

With the Internet Age and technology progressively advancing every year, the usage of Artificial Intelligence (AI) along with Machine Learning (ML) algorithms has only increased since its introduction to society. Specifically, in the healthcare field, AI/ML has proven to its end-users how beneficial its assistance has been. However, despite its effectiveness and efficiencies, AI/ML has also been under scrutiny due to its unethical outcomes. As a result of this, two polarizing views are typically debated when discussing AI/ML. One side believes that AI/ML usage should continue regardless of its unsureness, while the other side argues that this technology is too …

Teaching During Covid-19: The Lived Experiences Of Title I Educators Transitioning From Face-To-Face Instruction To Remote Instruction, Nicole Boykins

Electronic Theses and Dissertations

The purpose of this study was to investigate how school closures resulting from the COVID-19 pandemic impacted school educators who teach in Title I schools serving minority students located in a southern region of the United States. Due to the swift nature of the COVID-19 pandemic and the massive impact on many communities’ health and well-being, government officials moved quickly to close schools. Teachers, much like everyone else, had little voice in the launch of remote learning, expectations of remote teaching, or how to best support students and families during a global pandemic. Educators had to rely on their skills …

A Cleave Within The Piney Woods: Nacogdoches, Stephen F. Austin State University And How Racial Integration Divided The Town And Gown, Caitlin Hornback

Electronic Theses and Dissertations

Stephen F. Austin State University was once the pride and joy of the city of Nacogdoches, Texas. When the Texas State Legislature began to look for a location for their new state normal school, the people of the East Texas town fought to have it built there and the Stephen F. Austin Teacher’s College opened its doors in September 1923 to a proud community. Through the trials and tribulations of early twentieth century events, the school managed to stay afloat and grow in numbers. Dr. Ralph W. Steen became the president of the college in 1958 and he oversaw a …

Detection, Occupancy, Abundance, And Mercury Accumulation Of The Alligator Snapping Turtle (Macrochelys Temminckii) In Texas, David Rosenbaum

Electronic Theses and Dissertations

Land use practices and physical alterations of ecosystems result in habitat loss and fragmentation, while chemical alterations, such as pollutant input, reduce habitat quality and health of exposed organisms. Here, I investigated the effects of watershed- and local-scale environmental variables on the occupancy, abundance, and mercury accumulation of a threatened aquatic species (Macrochelys temminckii, i.e., alligator snapping turtle) within the southwestern periphery of its distribution. Hierarchical modeling suggested the distribution of the species is more affected by watershed-scale land-cover than local habitat, and provided a baseline estimate of average species abundance across its range in eastern Texas. Abundance …

Detection And Occurrence Of Nerodia Harteri (Serpentes: Colubridae) In An Upper Portion Of The Brazos River Watershed, Jessica Yates

Electronic Theses and Dissertations

Semiaquatic snakes are disproportionately impacted by habitat alteration adjacent to wetlands because of their reliance on both terrestrial and aquatic habitats. Brazos River Watersnakes, Nerodia harteri, are endemic natricines with one of the most restricted geographic ranges in North America. I quantified detection and site occupancy probabilities of N. harteri and its sympatric congeners (N. erythrogaster and N. rhombifer), as well as microhabitat selection within the Nerodia community. Within occupied transects, search effort was positively correlated with detecting N. harteri, whereas environmental and/or habitat variables were better predictors for detecting the sympatric congeners. Microhabitat selection between …

Assessing The Live Bait Industry And The Ecological Status Of Invasive Cyprinodontiformes (Sheepshead Minnow: Cyprinodon Variegatus And Gulf Killifish: Fundulus Grandis) In Texas Streams, Erin Shepta

Electronic Theses and Dissertations

The introduction of invasive species is one of the greatest threats to global biodiversity. Once established, invasive species often cause irreversible ecological damage on native communities. Here, I investigated the pathway of introduction and ecological impacts of the sheepshead minnow (C. variegatus) and the gulf killifish (F. grandis). Both species were thought to have been introduced into inland Texas waters via bait-bucket releases and have caused native populations of their inland congeners to decline. While I did not find evidence that either species were being sold in inland shops, bait industry experts did reveal other potentially …

An Application Of Differential Mathematical Modeling Techniques To Study The Ongoing Rabies Epizootic In China, Christopher Turner

Electronic Theses and Dissertations

Rabies remains a global public health issue with a wide variety of neurological symptoms such as confusion, slight paralysis, hypersalivation, and hydrophobia. Rabies is usually fatal once symptoms appear. Many species are reservoirs for rabies, such as foxes, racoons, and wild dogs, which in turn can transmit the disease to humans, leading to complex transmission chains. There is a long latent period of rabies, between 1 to 3 months after infection, which further complicates control efforts. Mathematical modeling is a valuable tool in the study of infectious disease outbreaks and there have been many models applied to rabies outbreaks. However, …

Effect Of Mycorrhizae Inoculation On The Growth And Success Of Three Taxodium Distichum Hybrids In Saline - Impacted Coastal Soils, Elif Ilhan

Electronic Theses and Dissertations

In 2008, Galveston Island was severely impacted by Hurricane Ike, resulting in high salt deposition in the soil and groundwater. This caused a loss of many native plant species. A study was initiated to determine effective ways to promote the growth conditions of three bald cypress genotypes (Taxodium distichum var distichum and Taxodium distichum var mexicanum crosses) in salt-affected soils. The treatments applied were mycorrhizae inoculation, fertilizer application, and a combination of mycorrhizae inoculation and fertilizer application. A total of sixty (60) trees planted in plots of three rows and divided into five randomized replication blocks of four treatments …

Covid-19’S Effects On Mortality Salience, Death Anxiety, And Worldview Defense, Sahvannah K. Shavers

Electronic Theses and Dissertations

Since late-2019, the world has been trying to overcome an invisible killer: COVID-19. With near constant reminders of the virus the knowledge that a tiny viral particle has potential to harm or even kill has become overwhelming for many. Terror Management Theory (TMT) suggests that when individuals are reminded of their own death people take part in culturally appropriate activities and defend their own culture as ways to alleviate this increased death anxiety. The current study aims to identify whether 1) reminders of COVID-19 prime death thoughts, 2) reminders of COVID-19 increase death anxiety, and 3) increased death anxiety from …

Stigma As A Barrier To Military Mental Health Services, Alicea Gray

Electronic Theses and Dissertations

A psychiatric disorder is perhaps an uncomfortable topic that isn’t discussed enough in the military. However, the nature of the profession (i.e., the possibility of combat exposure) increases the risk of mental health disorders in the military. Despite the increasing awareness of the effects of untreated mental health conditions, a treatment gap still exists within the military culture. The present study aims to describe the prevalence of stigma in the military, as well as examine related factors, such as leadership behaviors and the associations between endorsed and anticipated stigma and treatment seeking intentions. Utilizing a questionnaire, this study investigated the …

Aggregatibacter Actinomycetemcomitans Exploits And Modulates The Immune Response By Human Neutrophils For Survival In The Anaerobic Environment., Hazel Ozuna

Electronic Theses and Dissertations

Aggregatibacter actinomycetemcomitans (Aa) is a Gram-negative facultative anaerobe and an opportunistic oral pathogen, strongly associated with localized periodontitis and other inflammatory diseases. Periodontitis is a chronic inflammation of the periodontium resulting from the inflammatory response of the host towards the dysbiotic microbial community present at the gingival crevice. The host immune response creates a hostile environment for microorganisms; therefore, it is important for Aa to be able to regulate the necessary genes to survive and thrive in such an environment. Aaexpresses several virulence factors such as a cytolethal distending toxin (Cdt), lipopolysaccharide (LPS) and leukotoxin A (LtxA), …
