Legacy And Emerging Per- And Polyfluoroalkyl Substances : Analysis, Environmental Distribution, And Bioconcentration, Richard Anthony Brase

Legacy Theses & Dissertations (2009 - 2024)

Per- and polyfluoroalkyl substances (PFAS) constitute a broad class of anthropogenic chemicals that have been used in numerous industrial and consumer-product applications since the late 1940s. The environmental persistence of these compounds in combination with their widespread commercial use have led PFAS to be recognized as contaminants of concern on the global scale. Despite regulatory efforts calling for the decreased use of certain perfluorocarboxylic and -sulfonic acids referred to as “legacy” PFAS, these compounds continue to be detected in both environmental and biological matrices. Moreover, manufacturers have begun to replace the legacy PFAS with emerging alternatives for which the regulations …

Application Of Direct Analysis In Real Time-High Resolution Mass Spectrometry To Genus- And Species-Level Differentiation And Identification Of Coral, Jessica Mary Hayes

Legacy Theses & Dissertations (2009 - 2024)

Coral reefs are one of the most biologically diverse ecosystems, and the accurate identification of the species is essential for diversity assessment, species delimitation and conservation. Current species and genus determination approaches are time consuming, resource intensive and can be highly subjective. To explore the hypothesis that the small molecule profiles of coral are species and genus specific, and can be used as a rapid tool to catalogue, classify and identify coral genera and species, the small-molecule chemical fingerprints of coral belonging to the species Acanthastrea echinata, Catalaphyllia jardinei, Duncanopsammia axifuga, Echinopora lamellosa, Euphyllia divisa, Euphyllia paraancora, Euphyllia paradivisa, Galaxea …

Study Of Primary Cilium Structure And Intraflagellar Transport, Shufeng Sun

Legacy Theses & Dissertations (2009 - 2024)

Primary cilia are hair-like protrusions that stem from the basal bodies in the cytoplasm and extend into the extracellular space to sense signals. Intraflagellar transport (IFT) functions to transport cargo molecules into and out of the ciliary compartment to assemble, maintain, and disassemble the cilia. Accurate knowledge of the three-dimensional (3D) structure of primary cilia and precise details of the IFT profile is the foundation for understanding the sensory functions of primary cilia. This work covers three aspects of primary cilia. Firstly, we obtained and analyzed the overall 3D architecture of the complete primary cilia axoneme region using serial section …

Behavioral, Endocrine, And Neural Responses To Stress In Postpartum And Nulliparous Rats : Potential Mechanisms Of Postpartum Stress Resilience, Joanna Medina

Legacy Theses & Dissertations (2009 - 2024)

Major depressive disorder is one of the most pervasive psychiatric illnesses in the United States. Women are at greater risk for developing depression, particularly during their childbearing years. Approximately 17% of new mothers develop postpartum depression within 4 weeks after parturition. The risk for postpartum depression is even greater in women who do not breastfeed or stop breastfeeding early. Major depressive disorder and postpartum depression share the same symptomology and common etiological bases. Dysregulated stress responses, dopamine activity, and neuroinflammation are recognized mechanisms for depression. The transition to motherhood encompasses physiological and behavioral adaptations in the brain essential for ensuring …

Graduate Students' Intrinsic Motivation In Fully Online Courses, Ahmed Alahmari

Legacy Theses & Dissertations (2009 - 2024)

Motivation in general is one of the most important components of the process of learning and teaching in any educational environment, and it can explain the success or failure of student. In online learning, learners tend to study on their own and intrinsic motivation is particularly the main source that triggers and sustains learning process (Hartnett, 2016; Johnson et al., 2015; Shroff et al., 2007). Therefore, learners need high levels of intrinsic motivation to ensure success in their studies. Despite the emerging research regarding online learning, little attention has been given to graduate students’ intrinsic motivation in online courses. Therefore, …

Legacy Theses & Dissertations (2009 - 2024)

Forensic entomology is the study of insects that colonize human/animal wounds and remains and their development for use in legal contexts. It has numerous facets and applications including: estimation of time since death; investigation of neglect/abuse of children and the elderly; and determination of the presence of toxins and drugs as a potential cause of death. In order for the discovered insects to be of forensic utility, accurate species identification is crucial. Current methodologies for species determination rely on the knowledge and expertise of an entomologist; exhaustive taxonomic keys; and access to adequate equipment and facilities; resources which are often …

Change And Continuity In Biology, Gunnar O'Neill Babcock

Legacy Theses & Dissertations (2009 - 2024)

This dissertation considers various examples of change and continuity in biology. In particular, it focuses on the conceptual possibilities during the fission of microorganisms and genes when they multiply or replicate. Among the kinds of conceptual revision that are outlined in the first two chapters, the three chapter argues that certain concepts such as death, reproduction and organism have limited applicability in certain domains of biology. The fourth chapter investigates whether synthetic genomes should be considered parts of genetic lineages. It concludes that synthetic genomes are parts of the lineages upon which they were modeled. The final chapter aims to …

Perceiving Organization As An Entity : The Relationship Of Entitativity And Organizational Justice Perception, Wei Zhuang

Legacy Theses & Dissertations (2009 - 2024)

Entitativity is an important group construct that has received little attention in the organizational psychology literature. The current study based on 343 employed individuals explores the potential role of entitativity perceptions of organizations on the relationship between justice perceptions and employees’ emotional and behavioral reactions. Results of a three-wave survey study suggest that entitativity perceptions are positively associated with employees’ experienced gratitude toward organizations but have no relationship with employees experienced anger toward organizations. In addition, this study provides evidence that positive emotions can mediate the effect of justice perceptions on positive behavioral outcomes, and negative emotions can mediate the …

The Effects Of 17alpha-Hydroxyprogesterone Caproate On The Development Of The Mesocortical Dopamine Pathway And Cognitive Behavior, Melanie Lolier

Legacy Theses & Dissertations (2009 - 2024)

This dissertation examined the complex developmental impact of the clinically relevant synthetic progestin 17α-hydroxyprogesterone caproate (17-OHPC) on medial prefrontal cortex (mPFC) development. In rodents, the effects of 17-OHPC are subtle, but significant. In the Chapter II, we observed that 17-OHPC abolishes sex differences in dopaminergic fiber innervation and alters microglia phenotype in the prelimbic and infralimbic areas by the end of the first postnatal week. In the third chapter, the overall effect of 17-OHPC on the ontogeny of dopaminergic fiber innervation and synaptic bouton density were used to characterize the timing and duration of treatment effects in the mPFC. In …

To Burn Or Bury? That Is The Question : The Late Bronze Age And Iron Age In Northern Europe, Petra N. Peretin

Legacy Theses & Dissertations (2009 - 2024)

Changes in social organization can be studied through several different avenues one ofwhich is through mortuary patterns. Here we will be looking at changes in social organization during the Late Bronze Age and Iron Age in Northern Europe using mortuary and osteological data. If we study how each community interacts, mourns, stores, transports, and buries their dead then we can learn about the underlying mechanisms that transform and maintain a society, and gain insight into the societal and economical shifts of the Late Bronze Age and Iron Age in this region. These changes will be determined by analyzing the distribution …

A Novel Role For Neurotensin In Regulation Of Stem Cell Function In The Small Intestine, Stephanie Rock

Theses and Dissertations--Toxicology and Cancer Biology

Neurotensin (NT) is a nutrient-regulated gut hormone that plays important roles in lipid absorption, obesity, metabolic disorders, and normal and neoplastic growth in the intestine. In this study, we 1) elucidate the mechanisms regulating NT release from endocrine cells, 2) examine the role of NT on proliferation and stem cell function in the small intestine and 3) define the effects of NT on colorectal cancer stem cells. We report that NT release from endocrine cells is enhanced by the MAPK scaffold protein Kinase Suppressor of Ras 1 (KSR1) and the exocyst complex component 70 (Exo70). Moreover, free fatty acid stimulated …

Antebellum Black Climate Science: The Medical Geography And Emancipatory Politics Of James Mccune Smith And Martin Delany, Colin Fisher

History: Faculty Scholarship

This article argues that two prominent antebellum Black physicians—James McCune Smith and Martin Delany—developed competing scientific theories of nature’s impact on the human body in response to the climatic theories of the American Colonization Society, polygenist race scientists, and southern defenders of slavery. It further argues that the physicians’ divergent conclusions regarding nature’s agency played a significant role in underwriting arguably the most important and consequential political debate in antebellum Black America—namely, the dispute between integrationists who advocated remaining in the United States and fighting for equality and emigrationists who argued that America was so hopelessly racist that African Americans …

Residual Spatial Autocorrelation In Macroecological And Biogeographical Modeling: A Review, Guetchine Gaspard

Theses and Dissertations--Geography

Macroecological and biogeographical modelers have predicted the distribution of species across space relying on the relationship between biotic processes and environmental variables. Such a method employs data associated, for instance, with species abundance or presence/absence, climate, geomorphology, and soils. Statistical analyses found in previous studies have highlighted the importance of accounting for the effects of spatial autocorrelation (SAC), which indicates a level of dependence between pairs of nearby observations. A consensus has existed that residual spatial autocorrelation (rSAC) can substantially impact modeling processes and inferences. However, more emphasis should be put on identifying the sources of rSAC and the degree …

Micromending The Metabolic Rift: An Analysis Of Food Waste Composting Systems In Lexington, Kentucky, Casey Byrd

Theses and Dissertations--Geography

The metabolic rift theory explores materials and social exchanges between rural and city communities and human-nature relations. Metabolic rifts can exist both environmentally and socially and are often geographically or culturally unique. Ultimately the metabolic rift is earmarked by increasing disconnection between humans and their environment. This thesis draws upon life cycle analysis studies, social-economic studies, and environmental and sustainability studies to argue that large-scale contemporary urban composting efforts, although well intended, are insufficient to mitigate the effects of the metabolic rift. Mobilizing theories around capitalism and the metabolic rift, this research paper connects social, environmental, and economic notions of …

Bio-Spatial Policing In Theory And Practice: Examining Impacts And Resistance Through Mobilities And Children's Everyday Life, Emily Kaufman

Theses and Dissertations--Geography

Despite decades of reforms and technological innovations, increasing evidence shows that state securitization disproportionately harms already racially, spatially, and socio-economically marginalized communities. My research investigates uneven impacts of state securitization, from punitive welfare programs to school surveillance to policing. Across sites, I focus on scales, voices and the everyday lived experiences often left out of scholarly discourse and sensational media. In the current climate of growing awareness and scholarship on police violence, my dissertation addresses three less-studied areas: 1) the interplay between racial, gendered, spatial, and technified police practices; 2) how these practices impact the everyday lives of those racially …

Effects Of Season And Nutrition On Insulinemic Responses In Insulin Dysregulated Horses, Erica Lyn Macon

Theses and Dissertations--Veterinary Science

Insulin dysregulation (ID) is the main risk factor for the development of hyperinsulinemia-associated laminitis (HAL). ID in the equid has been extensively researched; however, recommendations for diagnosing and managing ID horses have originated from work completed in other models, such as the ID pony and healthy horse. Therefore, our overall objective was to improve current diagnostic tools and nutritional management strategies by investigating the effect of season, the fed and fasted state on the oral sugar test (OST) and dietary nutrient content on insulinemic responses in the ID horse. To address this, four main objectives with three specific aims were …

A Quantitative Phenomenological Study Of The Proliferated Use Of Electronics And The Impact On The Communication Skills Of Prekindergartens, Pamela B. Colbert

Doctor of Education Dissertations

Children who have a deficit in language as they enter school continue to be behind their peers as they progress from grade to grade. During the COVID-19 pandemic, many children were unable to attend school or preschool in person. Children develop language best in face-to-face environments. Previous literature did not include how the pandemic and the increased use of remote learning using technology might impact kindergarten readiness. This study adds to the body of knowledge by including perceptions of parents after remote learning during the COVID-19 pandemic. I utilized a quantitative phenomenological research design. Data were collected using a questionnaire …
