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 …

This paper examines the US-Cuban relationship during the first military occupation of Cuba from 1898 to 1902, to show the role of high modernist state building in the occupation and the scope of Cuban participation in this endeavor. This is evidenced by heavily examining the annual reports of the US Military Governor General of Cuba and the US appointed civil secretaries of the Cuban government. This research differs from previous studies in the field by introducing James C. Scott’s concepts of legibility and high modernist state building, as well as suggesting that the Cuban civil secretaries participated within a limited …

Characterization Of Adiposity And Inflammation Genetic Pleiotropy Underlying Cardiovascular Risk Factors In Hispanics., Mohammad Yaser (Anwar)

Electronic Theses and Dissertations

The observed overlap between genetic variants associated with both adiposity and inflammatory markers suggests that changes in both adiposity and inflammation could be partially mediated by common pathways. The pervasive but sparsely characterized “pleiotropic” genetic variants associated with both adiposity and inflammation have been hypothesized to provide insight into the shared biology. This study explored and characterized the genetic pleiotropy underpinning adiposity and inflammation using genetic and phenotypic observations from the Cameron County Hispanic Cohort (CCHC). A total of 3,313 samples and >9 million single nucleotide polymorphisms (SNPs) were examined in this study. Mixed model genome-wide association studies (GWAS) were …

Language Ability And Concurrent Predictors Of Pragmatic Communication In Children With Williams Syndrome Or 7q11.23 Duplication Syndrome., Amanda G. Harmon

Electronic Theses and Dissertations

The present project examined the language abilities of children with two reciprocal neurogenetic disorders: Williams syndrome (WS), which is caused by a hemideletion of 26 - 28 genes on chromosome 7q11.23, and 7q11.23 duplication syndrome (Dup7), which results from an extra copy of the same 26 - 28 genes. Appraising the language of children with WS and Dup7 helps in understanding the communication difficulties they encounter. There were three research goals. The first was to determine the overall level of language and communication ability as measured by the Children’s Communication Checklist-2 (CCC-2; Bishop, 2006) for each syndrome, relative to chronological …

This thesis consists of a collection of linked short stories, connected at the intersections of medicine, public health, race, gender, and socioeconomics. The Sick Ones was completed during a time of social unrest and the emergence of the Covid-19 virus. Inspired by medicine’s history of exploiting sick, poor, and racialized bodies, The Sick Ones explores the treatment of illness and societal woes in a near-speculative future. Each story is plot-driven, but complimented by a protagonist who keeps the narrative grounded, as they attempt to survive unprecedented circumstances. Some of the protagonists are complicit in their own medical exploitations, while others …

Statistical Approaches Of Gene Set Analysis With Quantitative Trait Loci For High-Throughput Genomic Studies., Samarendra Das

Electronic Theses and Dissertations

Recently, gene set analysis has become the first choice for gaining insights into the underlying complex biology of diseases through high-throughput genomic studies, such as Microarrays, bulk RNA-Sequencing, single cell RNA-Sequencing, etc. It also reduces the complexity of statistical analysis and enhances the explanatory power of the obtained results. Further, the statistical structure and steps common to these approaches have not yet been comprehensively discussed, which limits their utility. Hence, a comprehensive overview of the available gene set analysis approaches used for different high-throughput genomic studies is provided. The analysis of gene sets is usually carried out based on …

Modified-Half-Normal Distribution And Different Methods To Estimate Average Treatment Effect., Jingchao Sun

Electronic Theses and Dissertations

This dissertation consists of three projects related to Modified-Half-Normal distribution and causal inference. In my first project, a new distribution called Modified-Half-Normal distribution was introduced. I explored a few of its distributional properties, the procedures for generating random samples based on Bayesian approaches, and the parameter estimation based on the method of moments. The second project deals with the problem of selection bias of average treatment effect (ATE) if we use the observational data. I combined the propensity score based inverse probability of treatment weighting (IPTW) method and the directed acyclic graph (DAG) to solve this problem. The third project …

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 …

Aspects Of Causal Inference., John A. Craycroft

Electronic Theses and Dissertations

Observational studies differ from experimental studies in that assignment of subjects to treatments is not randomized but rather occurs due to natural mechanisms, which are usually hidden from researchers. Yet objectives of the two studies are frequently the same: identify the causal – rather than merely associational – relationship between some treatment or exposure and an outcome. The statistical issues that arise in properly analyzing observational data for this goal are numerous and fascinating, and these issues are encompassed in the domain of causal inference. The research presented in this dissertation explores several distinct aspects of causal inference. This dissertation …

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 …

"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 …

Automatic Target Recognition With Convolutional Neural Networks., Nada Baili

Electronic Theses and Dissertations

Automatic Target Recognition (ATR) characterizes the ability for an algorithm or device to identify targets or other objects based on data obtained from sensors, being commonly thermal. ATR is an important technology for both civilian and military computer vision applications. However, the current level of performance that is available is largely deficient compared to the requirements. This is mainly due to the difficulty of acquiring targets in realistic environments, and also to limitations of the distribution of classified data to the academic community for research purposes. This thesis proposes to solve the ATR task using Convolutional Neural Networks (CNN). We …

Plasma Resuscitation Attenuates Intestinal Barrier Disturbance Following Hemorrhagic Shock., Jessica E. Schucht

Electronic Theses and Dissertations

Background: Intestinal ischemia-reperfusion injury (IIRI) following resuscitated hemorrhagic shock (HS/RES) leads to endothelial damage, microcirculatory dysfunction and intestinal barrier breakdown, increasing intestinal permeability. This pathologic process contributes pathophysiology of multiple organ dysfunction syndrome (MODS) in some trauma patients. Although vascular smooth muscle machinery remains intact, microvascular vasoconstriction occurs secondary to endothelial cell damage, resulting in further ischemia and organ injury. Used separately, resuscitation with Fresh Frozen Plasma (FFP) or Direct Peritoneal Resuscitation (DPR) improves the intestinal microcirculation and alleviates organ injury. Further examination of these effects individually or combined could aid in the resuscitation of hemorrhagic shock. Methods: Sprague Dawley …

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 …
