Exploring The Relationship Between Behaviour And Neurochemistry In The Polyphenic Spider, Anelosimus Studiosus (Araneae: Theridiidae), Jennifer B. Price

Electronic Theses and Dissertations

The importance of social behaviour is evident in human society, but there are both costs and benefits associated with cooperation and sociality throughout the animal kingdom. At what point do the benefits outweigh the costs, and when do selective pressures favour sociality and colonization over solitude and independence? To investigate these questions, we have focused on an anomalous species of spider, Anelosimus studiosus, also known now as the northern social spider. Throughout its broad range, A. studiosus is solitary and aggressive, but recently, colonies of cooperative and social individuals have been observed at northern latitudes. This leads to two …

Endothelial Hspa12b Is A Novel Protein For The Preservation Of Cardiovascular Function In Polymicrobial Sepsis Via Exosome Mir-126, Xia Zhang

Electronic Theses and Dissertations

Sepsis is the most frequent cause of mortality in most intensive care units. Cardiovascular dysfunction is a major complication associated with sepsis, with high mortality rates up to 70%. Currently, there is no effective treatment approach for sepsis.

The integrity of the endothelium is fundamental for the homeostasis of the cardiovascular system. Sepsis induces endothelial cell injury which is the key factor for multiple organ failure. The increased expression of adhesion molecules and chemokines in endothelial cell promotes leukocytes infiltration into the tissue. The loss of tight junction proteins and increased permeability of the endothelial cells will provoke tissue hypoxia …

The Combined Effects Of Leptin And Coenzyme Q10 In Ameliorating Obesity- Induced Infertility In Female Rats, Adekunle Adedeji

Electronic Theses and Dissertations

Infertility is one of the major problems of obesity. Studies have shown that administration of leptin reversed obesity-induced infertility in rats and mice. Coenzyme Q₁₀ (CoQ₁₀) is an antioxidant and also supplies the energy needed for ovulation and embryo development. We hypothesized that leptin when combined with CoQ₁₀ could greatly improve obesity-induced infertility. The results showed a significant decrease in food intake, body weight, and the regular estrous cycle was restored after treatment with leptin+CoQ₁₀. There was a significant increase (p10 significantly (p10 can improve fertility in obese infertile female rats. This study could …

The Church, State, And Literature Of Carolingian France, Steffan James Geiter

Electronic Theses and Dissertations

This thesis examines the eighth century rise in power of the Carolingian Church and the Carolingian dynasty through an early promise of religious revival, monarchial revival, and increased Papal power. Such aims gained the Carolingians a powerful in the Church. Aided by Boniface (672-754 AD) and the Church, the Carolingians replaced the Merovingians in Francia. In conjunction with this revival, Church scholars dictated a reformation of kingship in treatises called the Speculum Principum. A king’s position became tremulous when they strayed from these rules, as it betrayed their alliance. Ultimately, Louis the Pious (778-840 AD) faced deposition after they …

The bacterium Rhodococcus is a potential source for novel antimicrobial metabolites. Recently, the Rhodococcus strain MTM3W5.2 was isolated from a soil sample collected from Morristown, East Tennessee and was found to produce an inhibitor molecule that is active against similar Rhodococcus species. The aim of this research is to extract, purify, and characterize the active compound. The compound was obtained from both agar and broth cultures of strain MTM3W5.2 and purified by primary fractionation of crude extract on a Sephadex LH-20 column, followed by semi-preparative reversed phase column chromatography. Final purification was achieved using multiple rounds of an analytical C …

(En)Visioning Resistance: Applications Of The Battlefield Myth In The War Scroll As A Window Into The Theological Development Of The Community, James Prather

Electronic Theses and Dissertations

The War Scroll (1QM) from Qumran is a composite document and is the result of a complex redactional process. It is the goal of this thesis to provide a historical proposal for the redaction of 1QM based on conflicting eschatological combat theology found within. Beginning with the earliest roots of ancient Israelite combat mythmaking and its continued evolution into the late Second Temple Period, writers appropriated and adapted the Israelite Battlefield Myth to envision theologies of resistance against oppression. Looking at the various adaptations and the social milieu in which each was written, it is possible to identify different trajectories …

Epistemology In The Churches Of Christ: An Analysis And Critique Of Thomas B. Warren, Derek Estes

Electronic Theses and Dissertations

This thesis seeks to understand at least one prevalent religious epistemology in the Churches of Christ by exploring the work of Thomas B. Warren. To accomplish this goal, I first offer a descriptive analysis of Warren’s theory of knowledge followed by an assessment of its strong and weak points. Ultimately finding his epistemology unsatisfying, I conclude the thesis by highlighting recent developments in religious epistemology that might point the way forward in accounting for knowledge of God in a theologically and philosophically robust way.

An Investigation Of Hydrogeologic, Stratigraphic, And Structural Controls On Acer Grandidentatum Communities In A Karst Landscape, Owl Mountain Province, Fort Hood Military Installation, Texas, Melinda S. Faulkner

Electronic Theses and Dissertations

The Owl Mountain Province is located within the Fort Hood Military Installation, an approximately 880 km2 installation established in the 1940s in Bell and Coryell counties, Texas, which has undergone extensive land use changes associated with military training, maintaining much of the vegetation in early succession. This study investigates thelithologic, stratigraphic, and structural controls on the hydrologic, hydrogeologic, and geomorphologic evolution of the Owl Mountain Province as expressed by mesic vegetation communities, including Pleistocene relicts Acer grandidentatum, within karst terrains. These systems exhibit complexly overprinted speleogenetic evolutions within a dynamic groundwater regime resulting from regional climate shifts throughout the …

The Stratigraphic Position Of Fossil Vertebrates From The Pojoaque Member Of The Tesuque Formation (Middle Miocene, Late Barstovian) Near Española, New Mexico, Garrett R. Williamson

Electronic Theses and Dissertations

The stratigraphy of the Pojoaque Member of the Tesuque Formation near Española, NM is not well understood. This region, during the Middle Miocene, represented a dynamic alluvial fan-fluvial-lacustrine environment within the Española Basin while the Rio Grande Rift was active. Cavazza (1986) identified two paleodrainage systems (lithosome A, basin-margin facies and B, basin-floor facies) by means of sandstone and conglomerate petrology, paleocurrent, and sedimentary facies analyses. After x-ray diffraction analyses of claystones within lithosome B, mordenite was discovered, which is a zeolite mineral commonly found within volcanic rocks. This is significant because the presence of mordenite confirms Cavazza’s (1986) conclusion …

‘Untruths And Propaganda’ – Churches Of Christ, Darwinism, And The 1985-1986 Acu Evolution Controversy, Paul A. Anthony

Electronic Theses and Dissertations

In 1985-1986, Abilene Christian University endured what one observer called the worst attack in “size, nature and intensity” on a university affiliated with Churches of Christ. The flashpoint was whether two biology professors were teaching evolution as fact without refutation. The university denied it, but the controversy raged for two years. Left unanswered was the most basic of questions: Did ACU professors actually teach evolution without a creationist rebuttal? Which leads to another: Why in 1985 – 130 years after the publication of On the Origin of Species and 60 years after ACU had fired a professor who questioned readings …

The Texts We Play: Avatar Creation And Racial Invisibility In Role-Playing Video Games, Daniel L. Archer

Electronic Theses and Dissertations

This project sets out to address problems of racial inequalities in role-playing video games as part of a growing field of video game studies in literary criticism. As these games are an increasingly popular form of entertainment in contemporary culture, their potential effects on players cannot be ignored. If these games continue to reflect society in a way that perpetuates racist stereotypes, social progress will halt. In order to study these games from a literary perspective, then, this project combines both narratological and ludological approaches to video game studies in order to bring about new insight from two strong perspectives. …

Heidegger And Deleuze: The Groundwork Of Evental Ontology, James Scott Bahoh

Electronic Theses and Dissertations

This dissertation examines the concept of event, as found in the ontologies developed by Martin Heidegger (1889-1976) and Gilles Deleuze (1925-1995). The texts I focus on are Heidegger's Sein und Zeit (1927), "Vom Wesen des Grundes" (1928), "Vom Wesen der Wahrheit" (lecture 1930, print 1943), Beiträge zur Philosopie (vom Ereignis) (written 1936-38, but not published until 1989), and Deleuze's Différence et répétition (1968). My focus is on the way each philosopher advances an account of the event in relation to a set of key fundamental themes. For Heidegger, these are truth, difference, ground, and time-space. For Deleuze I also discuss …

Kant With Foucault: On The Dangers Of The Theoretical Reification Of The Subject To Freedom And The Need For A Practical Psychology, Matthew Gordon Valentine

Electronic Theses and Dissertations

In this dissertation I consider the question, "Is it possible to think the subject qua subject or must any theoretical attempt to understand the subject necessarily reify it?" To answer this question, I appealed to Immanuel Kant's distinction between theoretical and practical reason, noting that practical reason could think the subject as a free soul rather than as a naturally-determined object. I then divided the sciences of the subject into four general types to determine which science could think the subject qua subject. Three sciences were shown to necessarily reify the subject: empirical psychology, rational psychology, and heteronomous ethics. I …

Congenic And Functional Analysis Of Rat Mammary Cancer Susceptibility., Saasha Le

Electronic Theses and Dissertations

Breast cancer is a complex disease affected by genetic, epigenetic and environmental factors. The genetic architecture of breast cancer comprises of high to low penetrance alleles. Although low penetrance alleles associate with a small change in an individual’s risk to breast cancer, the total number of variants present and the high population frequency attributes to a much greater population based impact compared to rare high penetrance alleles. Animal models have been used to study these low penetrance modifier alleles in breast cancer. Different rat strains vary in their susceptibility to 7,12- dimethybenzanthracene (DMBA) induced mammary carcinogenesis, with the Wistar- Furth …

Electronic Theses and Dissertations

This dissertation explores the role of epigallocatechin-3-gallate (EGCG), as a potential treatment for patients with inflammatory bowel disease (IBD). IBD is a common disorder that causes a great deal of suffering. Our understanding of the etiologies, pathogenic mechanisms, and treatment targets continues to evolve. Many new therapeutic targets are making their way through the pharmaceutical pipelines. However, not all patients benefit from these therapies. EGCG has long been studied as an anti-cancer agent. Most of our understanding of this compound comes from the oncologic literature. As the pathways of oncology and inflammation converge, new lessons can be taken from the …

Identification Of Host Factors Required For Yersinia Pestis Macrophage Intracellular Survival And Their Impact On Vacuole Maturation, Acidification And Trafficking., Michael Graylin Connor

Electronic Theses and Dissertations

Y. pestis is a facultative intracellular pathogen and the causative agent of plague. This bacterium, while most noted or the Black Death during the European 14^th century, is not a historic pathogen but a re-emerging pandemic with both domestic and global impact. Y. pestis is capable of colonizing the macrophage, and actively subverts phagolysosome maturation to establish a replicative niche known as the Yersinia containing vacuole (YCV). The exploited host factors required to support the YCV are unknown. Here we identified a comprehensive list of host factors required for Y. pestis survival through a genome-wide RNAi high-throughput screen. We …

Reel Racism, Real Consequences : A Multiple Case Analysis Of Savior Films As Racial Projects., Eric A. Jordan

Electronic Theses and Dissertations

This thesis analyzes how four blockbuster movies released in the years 2000-2014 represent racial projects. Racial projects encompass anything that helps people understand race. Films are racial projects because of their racist portrayal of characters. Films can be used to train audiences to view race in various ways that may contribute to problematic colorblindness. Specifically, the “White Savior” and “Magical Negro” tropes are ways through which films tell the viewers what to expect from White characters and characters of color. Viewers walk away from these films having constructed a racialized schema about White and Black characters, which further supports the …

Cell-Based Therapies For Ischemic Cardiomyopathy : Investigations Of Intramyocardial Retention And Safety Of High Dose Intracoronary Delivery Of C-Kit Positive Cardiac Progenitor Cells, And Therapeutic Utility Of A Novel Population Of Cardiac Mesenchymal Stem Cells Expressing Stage-Specific Embryonic Antigen-3 (Ssea-3)., Matthew C. L. Keith

Role Of Phosphodiesterase-4 In Alcohol-Induced Organ Injury., Diana Veronica Avila

Electronic Theses and Dissertations

Alcoholic liver disease (ALD) remains a leading cause of death from liver disease in the U.S., and there is still no FDA-approved therapy. Alcohol metabolism leads to generation of free radicals and oxidative stress with a resultant formation of lipid peroxidation products, which, in turn, contribute to the development of ALD. Alcohol induced hepatic steatosis is the earliest and most frequent manifestation of ALD and a significant risk factor for progressive liver disease. Cyclic adenosine monophosphate (cAMP) signaling has been shown to significantly regulate lipid metabolism. Moreover, agents that increase cAMP have been shown to effectively mitigate oxidative stress both …

Claude Cahun, Marcel Moore, And The Collapse Of "Surrealist Photography"., Elizabeth Ann Driscoll Smith

Electronic Theses and Dissertations

This thesis probes the photographic oeuvre of Claude Cahun and Marcel Moore and their interpretation of Freudian fetishism. Cahun and Moore rework Freud’s theory to disrupt and invalidate various symbols conventionally associated with sexual difference, examining social, fictional, and historical dimensions of gendering and the shift that occurs when their parameters disintegrate. The first section examines the lovers’ portraiture and use of clothing—specifically the androgyny of early-twentieth century Paris fashion—in order to demarcate same-sex gaze, desire, and fetish. The second section covers the four years in which Cahun and Moore’s participation in the Paris Surrealist circles can be traced—from 1933 …

La Minga As A Model Of Food Justice? : A Thesis On The Motivations And Practices Of Immigrant And Native-Citizen Growers At La Minga Cooperative Farm In Prospect, Ky., Tyler Austin Short

Electronic Theses and Dissertations

Progressive and radical stakeholders in the local food system call for forms of agricultural production and distribution that dialectically oppose the dominant paradigm of corporate-controlled agribusiness. This ethnographic research engages with the question of whether La Minga is a model of food justice. I collected ethnographic data from May 2015 to March 2016 via informal conversations and semi-structured interviews with members of the farm as well as secondary data gleaned from literature on anarchism, political economy, and food and agriculture. La Minga serves as a small-scale example of immigrants and native-citizens exercising their human right to produce healthy, culturally-appropriate food …

Environmental Vegetation : A Possible Association With Cardiovascular Disease Risk., Ray Anthony Yeager Ii

Electronic Theses and Dissertations

The built environment affects numerous aspects of human health and wellbeing, including risk of cardiovascular disease (CVD), the leading cause of morbidity and mortality in both the U.S. and worldwide. The amount and quality of environmental vegetation, is an important aspect of the built environment that affects known CVD risk factors, including psychosocial stress, health behaviors, and exposure to air pollutants. Nevertheless, little evidence on the role of potential mechanisms and geographic scale in these relationships exists. Of previous studies that describe associations between vegetation and CVD outcomes, limited investigation has been performed to assess these observed relationships in differing …

Presence And The Actor's Craft., Casey Richard Moulton

Electronic Theses and Dissertations

The purpose of this thesis is to establish that Presence is essential to an actor’s craft. This thesis makes considerable mention of my own work on Naomi Iizuka’s Polaroid Stories, playing the part of SKINHEADboy, as well as making mention of the theoreticians and practitioners of Acting who have dealt with the subject of Presence. The parallels I draw between actor training and the sources from outside of the field of Acting feed not only into an understanding of how consequential Presence is for the actor, but also how Presence can affect the lives human beings. This thesis also contains …

An Evaluation Of Multiple Endmember Spectral Mixture Analysis Applied To Landsat 8 Oli Images For Mapping Land Cover In Southern Africa's Savanna., Fernando Ferreira Caixeta

Electronic Theses and Dissertations

Mapping land cover in southern Africa’s savannas using traditional pixel based remote sensing techniques can be very challenging due to the heterogeneity of its vegetation structure and the spectral difficulty in separating similar land covers across various land uses. In order to overcome these complications, a Multiple Endmember Spectral Mixture Analysis (MESMA) provides a potential remote sensing approach to quantify spectral variation in the physical environment at a subpixel level. The MESMA approach was applied in the study area of the Mayuni Conservancy, in Namibia. Results show that 32.3% of the study area is covered by photosynthetic vegetation (PV), 32.0% …
