Co-Flowering Community Effects On The Relative Contribution Of Pollen Quantity And Quality Limitation To The Reproductive Success Of Four Clarkia Species, Emma Moore

Electronic Theses and Dissertations

More than 60% of plant populations experience low pollen availability which limits seed production (pollen limitation). Pollen limitation occurs due to low quantity or quality of pollen delivered to stigmas. Despite its ubiquity in nature, to date we still have limited understanding of the drivers of pollen limitation in plant communities. Plants typically occur in diverse communities where pollinator sharing is common and can influence quality and quantity aspects of pollen limitation. Co-flowering species can attract larger numbers of pollinators or they can compete for pollinators affecting pollen loads on stigmas. Pollinator competition may also lead to higher rates of …

The Initial Validation Of A Self-Care Belief And Behavior Questionnaire In The Iecmh Workforce, Julia Najm

Electronic Theses and Dissertations

The Infant and Early Child Mental Health (IECMH) workforce is essential in improving the lives of vulnerable children and families. IECMH practitioners are exposed to challenging emotional experiences which increases their risk of internalizing disorders, burnout, and emotion regulation difficulties, especially in the time of COVID-19. Thus, it is important to identify possible interventions to increase provider wellness in the face of taxing work. The construct of self-care offers a promising area of study as a possible intervention point.

Exploring The Experiences Of Underrepresented Students Pursuing Health-Related Graduate Or Professional Programs, Alison Williams

Electronic Theses and Dissertations

For many years graduate and professional education programs for the health professions have sought to increase the diversity of their student body to include students from a wider variety of backgrounds. Increasing the diversity of healthcare providers is an essential component of addressing inequities in healthcare. However, despite initiatives to increase racial and ethnic diversity in the health professions, these professions remain largely White and female. Previous researchers have sought to identify the reasons that racial and ethnic minorities are underrepresented in healthcare, and the barriers to persistence and success. Little research exists explaining why men are underrepresented in the …

Geometric Morphometric Analysis Of Modern Viperid Vertebrae Facilitates Identification Of Fossil Specimens, Lance D. Jessee

Electronic Theses and Dissertations

Snake vertebrae are common in the fossil record, whereas cranial remains are generally fragile and rare. Consequently, vertebrae are the most commonly studied fossil element of snakes. However, identification of snake vertebrae can be problematic due to extensive variation. This study utilizes 2-D geometric morphometrics and canonical variates analysis to 1) reveal variation between genera and species and 2) classify vertebrae of modern and fossil eastern North American Agkistrodon and Crotalus. The results show that vertebrae of Agkistrodon and Crotalus can reliably be classified to genus and species using these methods. Based on the statistical analyses, four of the …

A Low Cost, Compact Electrochemical Analyzer Based On An Open-Source Microcontroller, Michael Kofi Darko Addo

Electronic Theses and Dissertations

Compared to other instruments for chemical analyses, electrochemical analyzers are relatively simple, inexpensive, easy to miniaturize and require little-to-no maintenance. However, like all commercially available instruments, commercial electrochemical analyzers like potentiostats primarily operate as black boxes with manufacturers providing little or no information about internal circuitry and programming. This practice can limit a researcher’s ability to develop new techniques or adapt an instrument for applications outside its typical use. In contrast, creators of open-source instruments release all the necessary information for reproduction of the hardware and software – minimizing such barriers to innovation in chemical analyses. Here, we report a …

Fortunately, utilizing advanced natural language processing (NLP) techniques, data harvested from social networks have been employed to investigate various social trends within healthcare, such as disease tracking and …

Effects Of Environmental Pollutants On Liver Disease: Role Of The Gut-Liver Axis., Ngozi Victoria Adiele

Electronic Theses and Dissertations

Polychlorinated biphenyls (PCBs) and polystyrene (PS) microplastics are environmental pollutants associated with various diseases including toxicant associated fatty liver disease (TAFLD). Previously, exposure to Aroclor 1260 (a PCB mixture) has been shown to exacerbate TAFLD, partly through Aroclor 1260 induced gut dysbiosis. Studies has also demonstrated that PS exposure alters gut microbiome composition and induced obesity. However, the effects of Aroclor 1260 on the gut and the effects of PS on the liver are still understudied. Therefore, we hypothesize that environmental pollutants will disrupt the gut-liver axis through changes in gut and its microbiome as well as changes in liver …

Where Are All The Women?: Using Role Congruity Theory To Explore The Experiences Of Female Interscholastic Athletic Directors., Nicholas Swim

Electronic Theses and Dissertations

Leadership in sport organizations continues to be male dominated, even as multiple scholars have argued and proven the importance of women holding sport leadership positions (Burton & Leberman, 2017; Darvin & Lubke, 2021; Schull, 2017). The lack of women attaining these positions leads to fewer opportunities for role modeling and mentoring experiences for female athletes. As Burden et al. (2010) argue, interscholastic athletic directors are important as they usually represent the first interactions for young athletes with people in sport leadership positions. Researchers have investigated this phenomenon at the intercollegiate level (Bower & Hums, 2013; Darvin & Lubke, 2021; Taylor …

Perception Is Reality! How Perception Shapes Our World., Nicole Clay

Electronic Theses and Dissertations

This thesis is an examination of the role different photography techniques play in how images are perceived. There have existed techniques for manipulating the perception of images since the creation of the camera. The techniques examined in this paper are editing, staging, and the use of captions. In recent years, perception has become a powerful tool for political parties to manipulate. This manipulation of perception has led to an increasing distrust in the images the media presents to the public. This paper does not seek to answer any questions but to encourage people to have a greater understanding of photography.

Why Are Measures Of Depression Imperfectly Correlated? An Empirical Investigation., Eric Joseph Smith

Electronic Theses and Dissertations

Depression remains one of the most prevalent and impactful mental health disorders worldwide. A large number of measures of depressive symptoms are currently available, all designed to assess the same underlying construct. However, the measures tend not to correlate highly with one another. Measurement error cannot fully account for this observation, suggesting that clinical heterogeneity – that is, differences in symptom coverage across measures – might contribute to the lower-than-expected correlation between measures. We conducted two concurrent studies to examine this hypothesis. In Study 1, we developed a coding scheme to categorize items into one of 10 symptom categories. We …

Americans worship in different churches, learn in disparate schools, and live in separate neighborhoods. Residential segregation has consequences that impact the economy, professional …

Epitranscriptomic Regulation In Breast Cancer And Pcb-Induced Liver Disease., Belinda Petri

Electronic Theses and Dissertations

Post-transcriptional RNA modifications including N6-methyladenosine (m6A) regulate mRNA stability, splicing, and translation. My research examined m6A in two disease models: breast cancer (BCa) and non-alcoholic fatty liver disease (NAFLD). Acquired resistance to endocrine therapies (ET) develops in approximately 20% of BCa patients with estrogen receptor α positive (ER+) tumors following treatment. The mechanisms by which tumor cells evade ET are not completely understood. Using a cell line model, we investigated the role of an m6A reader protein, HNRNPA2B1 (A2B1) that is upregulated in ET-resistant ER+ BCa cells. Stable overexpression of A2B1 in ET-sensitive MCF-7 cells (MCF-7-A2B1), results in ET resistance, …

New Methodologies For Sustainable Organic Synthesis In Water., Sudripet Sharma

Electronic Theses and Dissertations

Water is stable, benign, and green solvent. Its usage as a solvent in organic synthesis is significantly enhanced by micellar catalysis. However, replacing water as a reaction medium in organic synthesis is not sufficient to meet the sustainability challenges—excessive organic solvents are still required for product isolation and purification. Notably, solvents used in syntheses contribute to more than 80% of waste generation. In addition to solvents, the use of palladium in large amounts is also a problem for the future as it is a precious, low-abundance metal, and its supply is dwindling. Therefore, this dissertation highlights the various sustainable protocols …

The Relationships Between State-Level Economic Policies, Child Maltreatment, And Suicidal Behavior And Mortality., Yana B. Feygin

Electronic Theses and Dissertations

Suicide has proven to be difficult to predict and prevent at the individual level,1–3 so much so that a recent analysis of individual risk assessments found a maximal positive predictive value of 5.5% for suicide death,2 and suicide continues to be a leading cause of death among adolescents age 10-19 years.4 By targeting modifiable risk factors at the population level, policy has the potential to extend our reach to people and subgroups that are missed by individual level interventions. This ecological study of adolescent suicide rates, state policies, and child maltreatment in US states from 2005-2019 and Kentucky counties from …

Providers’ Effective Approach: Reducing Resistance To Insulin Treatment In Type 2 Diabetic Patients With Hyperglycemia, Eden A. Tsegay

Why Democracies And Autocracies Go To War: Comparing The Cases Of Iraq And Ukraine, Ketevan Chincharadze

Electronic Theses and Dissertations

History shows that both democratic and nondemocratic countries wage wars to advance their strategic interests. This study has comparatively analyzed two conflicts – the 2003-2011 U.S. invasion of Iraq and Russia’s ongoing war in Ukraine – to identify the trends that motivate both democratic and autocratic leaders to behave similarly by launching an invasion. The interpretive research of various memoirs, books, interviews, academic articles, news reports, and speeches, has uncovered that personal biases, particularly confirmation biases, play a significant role in motivating leaders to start a war. Leaders’ confirmation biases are often shaped by three prominent factors – historical memory, …

Vegetal Being: Dreamwork, Ritual, And Performance In Han Kang’S The Vegetarian, Briana Hanratty

Electronic Theses and Dissertations

In this thesis, I am writing towards an ecofeminist informed reading of the English version of The Vegetarian by Han Kang, translated by Deborah Smith. My aim is to display how, like an ecosystem of complex interdependency, it is impossible to separate body from theory from text from ecological context. To engage with this form of ecofeminism, I center an autotheoretical methodology with voices from ritual theory and performance theory in order to examine how Yeong-hye, the titular vegetarian of Han Kang’s novel, operates as a narrative-level metaphor for the desire for erotic ecology as a mode of ecological and …

The Queer Ecology Of Clouds In Nineteenth-Century British Poetics, Lucien Darjeun Meadows

Electronic Theses and Dissertations

Throughout the nineteenth century, British writers were interested in the emergent science of meteorology, and their lyrical writing (their “poetics”), from poetry to creative and scientific prose, often turns to clouds as both meteorological formations and as material metaphors for human-environment interactions. These writers frequently invoke clouds to disrupt or “queer” depictions of human-environment relationships built on human domination of environmental beings. Clouds, in poetic writing, help writers (and readers) instead experience subject-subject relationships of reciprocity—a collaborative, non-hierarchical way of existing with and learning from our ecological relatives.

Dwelling in the confluence of literary studies, queer studies, and ecology, The …

Historical Realism And Stoic Heroes In The Work Of John Williams, Cameron Sepede

Electronic Theses and Dissertations

This thesis investigates how John Williams’s three major works of fiction — Butcher’s Crossing, Stoner, and Augustus — are narratively structured around three main characters who embody the tenets of stoic and Emersonian transcendental philosophy, respectively. Williams uses these characters to promote and critique preconceived notions of heroic masculinity as structured within these philosophies. Through an analysis of form, this thesis will explore how Williams scaffolds his three main characters around the language and ideas present within each philosophical school. Williams’s portrayal of heroic masculinity, as seen through a feminist perspective, questions the ideal masculine hero, which will be …
