Transformative Experiential Impacts On Students: An Intervention, Stacy R. Bailey

Dissertations

Students’ successes in first-year writing courses at the university level are critical to academic success and degree completion. Fostering students' engagement in first-year writing courses has proved challenging for institutions of higher education (IHE). Utility value interventions (UV) employing social psychological intervention (SPI) methods have been implemented successfully to aid students in understanding the value of course content and improve achievement. Utility value is the perceived usefulness of a task or content. Similarly, transformative experience (TE) interventions have been implemented with success. Transformative experience is a learning outcome achieved when students re-conceptualize their out-of-school experiences as a result of their …

Pink Is The New Bull: The Feminization Of Pit Bulls In Visual And Literary Discourses As A Rescue Tactic, Stephanie Hogue

Master of Arts in American Studies Capstones

Since the 1980s, pit bulls have been portrayed in a raced, classed, and gendered national discourse that has associated them with minority males of color in low-income urban areas. This discourse has led to a villianization of the breed that has resulted in restrictions on pit bulls and their owners. This project seeks to explore the raced, classed, and gendered representations of pit bulls in cultural productions and the nuanced ways in which the intersectional identities ascribed to pit bulls have impacted their status as acceptable pets in the United States.

Revealing A Non-Canonical Role Of Anti-Apoptotic Mcl-1 In Early Embryonic Development, Xue Yang

Theses and Dissertations (ETD)

MCL-1, a well-known pro-survival BCL-2 family member, is indispensable for the survival of various cellular lineages and is also among the most frequently amplified genes in a variety of human malignancies. Gene ablation studies previously revealed that Mcl-1 deficiency leads to embryonic lethality around E3.5 during peri-implantation stage. Strikingly, the study did not detect any increase in apoptotic cells of the blastocyst, indicating a function of MCL-1 beyond regulating apoptosis. Our previous studies revealed an unrecognized role of MCL-1 in promoting mitochondrial physiology, which is independent of its classical anti-apoptotic function and requires being imported into the mitochondrial matrix. In …

Social-Ecological Factors Affecting Patient Shield Use Among Radiologic And Computed Tomography Technologists, Megan Housenick-Lee

Electronic Theses and Dissertations

Medical radiation is estimated to contribute to over 200,000 deaths annually. Recent increases in the use of radiation-producing medical imaging examinations have led to increasing cumulative radiation dose to the general public. Multiple measures have been taken to address this alarming trend, including physician education, technologist education on dose reduction, and equipment-facilitated dose reduction techniques. Shield use can reduce the primary beam by up to 95%. Medical imaging technologists are the primary individuals responsible for applying shielding during an examination. Currently, literature shows that technologists are not shielding individuals as often as they should.

After pilot testing, medical imaging technologists …

Interaction Between Fragments Of Tau Protein Investigated By Force Spectroscopy Using Afm, Anad Mohamed Afhaima

Theses and Dissertations

Over the last couple of decades, there has been rapidly growing interest in research of natively unfolded proteins. Some proteins from this group are implicated in a number of neurodegenerative diseases. One group of neurodegenerative diseases, taupathies, is associated with tau protein. A number of biophysical and spectroscopic studies have revealed that tau protein can expand to a largely extended state and to transition rapidly between many different conformations. Although many of the techniques that elucidate structure of macromolecules have provided important information about the folded states of proteins, important information about the transition between the extended conformation states remain …

Metastable-State Nh Photoacids And Organic Photo Carbon Monoxide Releasing Materials, Aluthwatte Rallage Nawodi Madhusanka Abeyrathna

Theses and Dissertations

The recently discovered metastable-state photoacids (mPAHs) can produce a large proton concentration with high efficiency and good reversibility upon irradiation with visible light with moderate intensity. Therefore, mPAHs can be conveniently incorporated in to different systems to control various proton-transfer processes. Recently, several applications of mPAHs have been demonstrated. However, none of the previously reported mPAHs can function at a pH 7.4. Thus, biological applications of mPAHs are limited. In this work, mPAHs that can reversibly release a proton in PBS buffer (pH = 7.4) under visible light are designed and synthesized. NH-PAH-1 is the first of this type of …
