Investigating Student Self-Beliefs And Learning Metrics In Online Courseware: A Quantitative Inquiry, Rachel Van Campenhout

Electronic Theses and Dissertations

Online courseware is an emerging educational technology that has the potential to reach students at scale. Designed with cognitive and learning science principles, courseware utilizes effective methods to maximize learning outcomes for students. Mindset (implicit theories of ability) and self-efficacy are two widely researched self-belief topics which have been shown to influence student learning outcomes and self-concepts. These self-belief theories are not specific to a domain and therefore could be measured and analyzed in relation to student learning metrics from any subject. The purpose of this nonexperimental correlational research study is to investigate the relationships between student self-beliefs and key …

Perceived Levels Of Teaching Self-Efficacy Among Advanced Ces Doctoral Students Engaging In External Pedagogical Experiences, Erika Williams

Electronic Theses and Dissertations

This quantitative study examined factors of internal preparation practices (i.e., coursework in college teaching, fieldwork in college teaching, and frequency of supervision) and external pedagogical experiences (i.e., holding a bachelor’s or master’s degree in teaching and adjunct faculty experiences in higher education) and their potential effects on teaching self-efficacy among counselor education and supervision doctoral students. This study identified both significant and non-significant relationships between the stated variables. Contrary to previous research (Suddeath et al., 2020), internal preparation practices did not significantly predict scores of teaching self-efficacy among this population. However, the findings suggest that participants holding a bachelor’s or …

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 …

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 …

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 …

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 …
