Prevention Of Chronic Inflammation By Targeting Macrophage Integrin Adb2, Cady Forgey

Electronic Theses and Dissertations

Macrophage integrin a_Db₂ promotes macrophage retention and accumulation within inflamed tissue, a key event in development of chronic inflammation. Recently, the P5 peptide was identified as a specific inhibitor for integrin a_Db₂ interaction with 2-(ω-carboxyethyl) pyrole (CEP), a ligand at inflammatory sites. This thesis aims to identify integrin a_D I-domain amino acids involved in binding P5 peptide and likewise to CEP. We propose that non-conserved, basic amino acids of the integrin a_Db₂ I-domain are responsible for binding to P5 peptide and likewise to CEP. Eight amino acids were analyzed by …

Teacher Perceptions Of Collegial Collaboration In An Academy Structure., Kristy Marie Field

Electronic Theses and Dissertations

Collaboration in is an often researched, many-named concept with a definition which has historically been unclear. What one calls collegiality another may call teacher teaming and yet another may refer to as professional networking. Scholars agree effective teacher collaboration can lead to higher student achievement, teacher efficacy, and teacher retention. However, as elusive as an agreed-upon definition may be an agreed-upon structure that fosters an effective version of this collaboration. When Ford began the Ford Next Generation Learning initiative, they embarked on the path to developing a school model that focused on school and community partnerships to support long-term, transformational …

Investigating The Disorder And Compaction Of Designed Minielastin Using Nuclear Magnetic Resonance., Ma Faye Charmagne Aquino Carvajal

Electronic Theses and Dissertations

Minielastins are elastin-based proteins with alternating hydrophobic and cross-link modules similar to tropoelastin. Tropoelastin is the ~70 kDa soluble monomeric precursor of elastin. The extracellular matrix protein, elastin provides elasticity to tissues and organs such as lungs, arteries and ligaments. The elastic properties of natural elastin are believed to be entropic in origin. In vivo, the elastin matrix is approximately 50% water by weight. Without water, elastin is brittle and hard. Minielastins, like tropoelastin, undergo a liquid-liquid phase transition upon an increase in temperature. Factors such as hydrophobicity, chain length and concentration affect the coacervation temperature, T_c. The …

Social Media And Fear: Social Media As A Catalyst For Political Fear In The United States., Shane R. White

Electronic Theses and Dissertations

Abstract: Using the American National Election Study data from the 2012 and 2016 surveys I explore how social media usage shapes fear. This is likely caused by the nature of social media leading to oversharing of sensationalized articles likely to elicit an emotional and fearful response. My findings suggest first that social media usage has a statistically significant effect on whether they would say they are afraid of a candidate (2012) and how afraid they say they are of the candidates (2016). Second, social media has little effect on economic fear, and may actually make people more hopeful about the …

The Ball Is In Your Court: A Phenomenological Study Examining College Athletes With Learning Disabilities And/Or Adhd On College Campuses., Stephanie Thea O'Donnell

Electronic Theses and Dissertations

Approximately only 1% of scholarly top-tier higher education published research focuses on the experiences of students with disabilities since the passing of the ADA in 1990 (Pena, 2014). Even fewer studies have explored the learning-disabled collegiate athlete experience. The purpose of this emerging phenomenological study is to understand the lived experiences of college athletes with learning disabilities and/or ADHD at NCAA Division 1 FBS institutions, giving voice to the untold stories, and commonalities amongst this population.

External Homophobia And Outness In Gay Men., Thomas Charles Isaak Jr

Electronic Theses and Dissertations

Prior studies regarding outness among gay men have often focused on internalized homophobia as a barrier to coming out for gay men, while less emphasis has been placed on external homophobia. Drawing upon social construction theory and Connell’s hierarchy of masculinity, I utilize data from the 2010 Social Justice Sexuality Project to complete an ordinary least square regression to examine the impact of external homophobia on the level of outness among the 987 gay men in this study. In this study, I find that gay men who were exposed to external homophobia reported decreased levels of outness. Further, I find …

Computational Behavioral Analytics: Estimating Psychological Traits In Foreign Languages., Kristopher Wayne Reese

Electronic Theses and Dissertations

The rise of technology proliferating into the workplace has increased the threat of loss of intellectual property, classified, and proprietary information for companies, governments, and academics. This can cause economic damage to the creators of new IP, companies, and whole economies. This technology proliferation has also assisted terror groups and lone wolf actors in pushing their message to a larger audience or finding similar tribal groups that share common, sometimes flawed, beliefs across various social media platforms. These types of challenges have created numerous studies in psycholinguistics, as well as commercial tools, that look to assist in identifying potential threats …

In Need Of A Hero? The Creation And Use Of The Legend Of General George S. Patton, Jr., Nathan Curtis Jones

Electronic Theses and Dissertations

During WWII, General George Patton became the hero Americans needed through the creation of a self-crafted brand and with help from journalists. After Patton’s death, opportunists forwarded a legend narrative that developed into a collective memory that morphed over time to meet contemporary challenges. Stakeholders of that collective memory commemorated and memorialized the dead hero for monetary and political gain, to promote patriotism, make military doctrinal changes, and even promote peace. Today, this collective memory has potential for the U.S. Army as it transforms civilians into soldiers and officers. This study contributes to history and memory studies by linking representations …

Privacy In Multigenerational Homes Before And Amidst Covid-19, Jennifer Luque

Electronic Theses and Dissertations

Multigenerational households in the United States are more prevalent now than they have been in the last forty years. In part, aging, illness, job loss, saving money, and even tradition are factors that contribute to the idea of multiple generations living together in one home. Given the health of the individuals, size of the home, and number of dedicated bedrooms and bathrooms, living multigenerational can have both positive and adverse effects. Many family groups fall into the category of multigenerational living. However, this study investigates the relationships between adults and senior family members in terms of privacy in the home. …

"Don't Put An 'Or' Where God Puts An 'And'": Constitutive Rhetoric In Queer Appalachia., Brooke Elizabeth Boling

Electronic Theses and Dissertations

Appalachians who use the word “queer” to specifically refer to being gay, lesbian, bisexual, transgender, queer, intersex, and/or asexual, are regularly faced with negotiating how these parts of their identity can exist simultaneously, as many both within and without the region believe it is impossible to be Appalachian and queer at the same time. Despite rampant homophobia in the region and external narratives suggesting that queer Appalachians do not exist, these folkx have carved out spaces for themselves to assert their identities and create community and belonging through rhetorical actions. Many of these spaces are online, taking place through digital …

Putting Cajuns On The Map: Music's Role In Popularizing Louisiana's Bayou Culture, Christine Broussard

Electronic Theses and Dissertations

Southern Louisiana witnessed a grassroots Cajun cultural revival whose most active years stretched across three decades in the latter half of the twentieth century. While important local and world events created conditions favorable to its development, actors and events within the Cajun musical sphere specifically, and the establishment and use of iconography within that sphere, played integral roles in sustaining the Cajun renaissance into the 1980s. Activist efforts that recast long-held negative tropes about Cajun culture ensured modern-day Cajuns had access not only to cultural traditions but to the same spaces created to help keep those traditions alive. While those …

The Interaction Of Adversity, Hope, Social Support, And Academic Resilience In Emerging Appalachian Adults, Daniel Joseph Gottron Jr.

Electronic Theses and Dissertations

The negative impact of adverse childhood experiences on both short-term and long-term wellbeing has been repeatedly validated across multiple populations. While adverse childhood experiences have been thoroughly researched in many contexts, this is not the case for Appalachia, which has often been relegated to the fringe of scholarly research, resulting in an overall lack of research on Appalachia. Further lacking is research into how protective factors might be utilized to help overcome adversity. While some recent research on the relationship between adverse childhood experiences, hope, and resilience has been conducted, it too has been limited to select populations. It is …

Analyzing The Longevity Of Sperm Within The Female Japanese Quail By Assessing Sperm Penetration Of The Perivitelline Layer Under Optimal And Suboptimal Conditions., Garret G. Ashabranner, Joey L. Bray

Electronic Theses and Dissertations

After mating, birds have the ability to store semen within the female reproductive tract. The sperm storage tubules will store and subsequently release semen to travel up the oviduct. Sperm cells that make the trek up the oviduct have a chance to fertilize the ovum. These sperm cells will bind to the perivitelline layer of the ovum and hydrolyze a hole in the perivitelline layer, where it has the possibility to fertilize the female sex cell. Analyzing the number of penetration points on the perivitelline layer is an effective way to analyze reproductive efficiency. Many environmental factor has its effect …

Multiphysics Computational Model Of Fluid Flow And Mass Transport In Aneurysm, Tanja Cupac

Electronic Theses and Dissertations

The abdominal aortic aneurysm is progressive, asymptomatic, and can eventually lead to rupture which is a catastrophic event leading to massive internal bleeding and possibly death. AAA cases have been characterized by the development of an intraluminal thrombus (ILT). The ILT correlates with the progression of hypoxia in the arterial wall. The extent that ILT presence reduces oxygen flux to the wall has not been quantified and there is rather a poor understanding of key parameters that can affect thrombus-mediated oxygen transport in AAA. The purpose of this study is to address this gap and to assess the effects of …
