Creating Safe Schools: An Exploratory Study Of Educator Perspective On Student Behavior And Restorative Practices In Schools Implementation, Rachel Danielle Vargas

Electronic Theses and Dissertations

Restorative practices in schools (RPS) is an Integrated Student Support process that many U.S. K-12 schools utilize to combat student behavior and racial disparities against students. Initial research suggests that RPS is a successful tool to drop suspension rates, create safe school environments, and help students stay engaged in school. However, there is not sufficient empirical evidence to support a successful implementation model, leading to mixed results and opinions about the effectiveness of RPS. The purpose of this study was to explore the program processes of RPS and determine effective implementation strategies that lead to successful student outcomes. Data were …

A Bioaffinity Self-Assembling Gel For Localized Delivery Of Immunotherapeutics, Ngoc Pham

Electronic Theses and Dissertations

Renal cell carcinoma (RCC) is a type of cancer in which malignant cells develop in the kidney tubules. Immune checkpoint inhibitors (ICI), including anti-PD-1 antibodies (aPD1), as monotherapies or in combination settings have advanced to the front-line treatment for patients diagnosed with RCC. Systemic infusion of ICI may render subtherapeutic concentrations in the lesions and increase risks of immune-related adverse events. To overcome these limitations, locoregional drug delivery has gained substantial interests as a modality in immuno-oncology. However, conventional intratumoral injections may be ineffective because the high interstitial fluid pressure in tumors resists drug retention and results in rapid local …

Aerodynamics And Turbulent Wake-Flow Characteristics Of Owls During Flapping Flight, Krishnamoorthy Krishnan

Electronic Theses and Dissertations

Owls exhibit unique flight capabilities in the low Reynolds number flow regime which is prone to complex viscous flow phenomena. They possess unique feather features and flexible wing structures which are postulated to help them fly nearly silently and stably at low speeds in a complex flow setting. Understanding the aerodynamics of owls could pave the way to enhance the future designs of small flying vehicles. Though it has been a focus of research over multiple decades, no conclusive agreement has been attained on the aerodynamic mechanisms associated with owl flight. Particularly, the aerodynamics of flapping owl flight is severely …

Loggerhead Shrike Detectability And Occurrence In Coastal South Carolina Urban Areas, Michelle Krauser

Electronic Theses and Dissertations

Grassland birds, such as the loggerhead shrike (Lanius ludovicianus), are threatened by extensive land-use change, including urbanization. Loggerhead shrikes have been declining since the early 1900s and are rare or extirpated in portions of their former range. Obtaining reliable population estimates of loggerhead shrikes is important to identify demographic trends and ensure conservation decisions are based on an accurate assessment of their current status. Imperfect detection, or the inability to detect every shrike during a survey, can result in biased population estimates. Estimating detection probability is labor-intensive and requires assumptions that are difficult to satisfy in most field studies. Understanding …

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 …

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. …

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 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 …

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 …

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 …

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 …

The Reception Of Isaiah's Suffering Servant In Thomas Aquinas' Theology Of The Cross, Daniel Waldow

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 …

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 …

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, …

The Mystagogical Catechesis Of Narsai Of Nisibis: Mēmrē 39 And 38 In Their Syriac Context, Jordan Ryan Turney

Electronic Theses and Dissertations

This thesis is a study of Narsai of Nisibis’s mēmrē on the sacraments of the baptismal liturgy that situates these mēmrē in their Syriac theological context and presents them as an important witness to Late Antique Christian mystagogy. Narsai is a significant figure in the Syriac Christian tradition, yet he has received comparatively little scholarly attention, especially in the West. However, an increase in editions and studies of Narsai’s work over the last century has led to a further awareness of his influence on Syriac Christianity. Several scholars have pointed out that these mēmrē bear a resemblance to other Late …
