Raising Consciousness: Challenging Diversity In Christian Publishing, Michael Omari Johnson

Masters Theses

The Christian publishing industry has overlooked the importance of diversity, particularly its impact on black American audiences. While studies show that diversity and inclusion can lead to more innovation through problem-solving, there persists a paradox where a lack of opportunities, disparities in wealth and employment and systemic prejudices can play a role in the ethnic and racial homogeneity of the Christian publishing industry. Thus, there are many barriers preventing people of color from emerging to the market, reflecting in the storytelling, content creation and audience of African-descent followers.

Native Plant Allelopathy: A Potential Approach To Limit Invasive Grass Encroachment In Thorn Forest Restoration, Emily A. Mullins

Theses and Dissertations

Less than 5% of the Tamaulipan thorn forest remains in the United States. For this reason, there have been many attempts at restoration of this ecosystem. Oftentimes these attempts are unsuccessful due to the high prevalence of invasive African grasses that outcompete the seedlings. In an effort to improve the efficacy of these restoration efforts, native plant allelopathy has been examined for its ability to exclude invasive guineagrass. Native species were surveyed and selected species were tested for allelopathy in laboratory bioassays. The species that exhibited allelopathy in the laboratory were then evaluated in pot experiments for their ability to …

Infection And Persistence Of Zika Virus In Female Immune-Competent Gray Short-Tailed Opossums (Monodelphis Domestica), Oscar Quintanilla

Theses and Dissertations

Zika virus (ZIKV) is a class IV RNA virus transmitted by Aedes species of mosquitoes. It produces flu-like symptoms, but recent studies have associated additional, more severe pathologies with ZIKV like microcephaly. Currently, no effective treatment options or vaccines exist. This is partly due to limitations of current animal models. Monodelphis domestica (the gray short-tail opossum) may serve as a proper model for ZIKV research. Here we test the susceptibility of M. domestica to ZIKV infection. Female, immune-competent subjects were injected with live ZIKV and analyzed serologically and histologically for evidence of ZIKV replication. ELISAs performed on sera confirmed that …

Samuel Daniel’S Lyric Reception: The Role Of Poet-Critics From Wordsworth To Winters, Caleb Mcghee

Electronic Theses and Dissertations

The Elizabethan poet Samuel Daniel was popular in his day, producing lyric, dramatic, and narrative poems. Contemporary anthologies, however, memorialize him primarily as a lyric poet, one that usually gets few entries. My thesis shows how Daniel had a minor reputation as a lyric poet by the 1960’s, despite having high-profile admirers. These well-known poet-critics who engaged with his work are essential to analyzing his lyric reputation: owing to the Romantic emphasis on the lyric, I begin with William Wordsworth and Samuel Taylor Coleridge’s reception of his lyrics in the 19th century. I then analyze the turn of the century …

Total Synthesis Of Cytotoxic Mansouramycins From Amino Acids, Beatriz Gamez

Theses and Dissertations

Natural products produced by plants, animals, and microorganisms are of significant importance in chemistry for being major sources of molecular scaffolds essential for new drug discovery. Mansouramycins are cytotoxic bioactive compounds containing isoquinoline skeletons with substituents on the quinone and pyridine rings that may be difficult to synthesize. Synthetic processes exist for compounds B and D, however, there exists an absence of simple synthetic approaches to all four alkaloids.

These changes in species dominance …

Differentiating Between Invasive And Native Populations Of Bighead And Silver Carp Using Ms-Aflp, Erika Renee Sarvela

Theses

When a species is introduced outside their native range, the genetic diversity of the introduced population is generally decreased due to the founder effect, and the fitness of individuals in the introduced population may decrease due to inbreeding depression. Invasive species are a paradox to this paradigm because while the initial population size of an invasive species may be small in their non-native range, the individuals are able to survive, eat, and reproduce so successfully, that they have deleterious effects on native species. One mechanism that invasive species use to overcome a lack of genetic diversity and adapt to their …

Real-Time Cloth Simulation On Virtual Human Character Using Enhanced Position Based Dynamic Framework Technique, Itimad Raheem Ali, Mazin Abed Mohammed, Talib A. Al-Sharify, Hoshang Kolivand

Baghdad Science Journal

Cloth simulation and animation has been the topic of research since the mid-80's in the field of computer graphics. Enforcing incompressible is very important in real time simulation.

The Frequency-Amplitude Response Of A Class Of Nonholonomic Systems, Colin Rodwell

All Theses

Nonholonomic systems have been investigated as models for locomotion due to the similarity between nonholonomic constraints and the no-slip condition of wheels or the Kutta condition of swimmers' tails. The focus of most past research has been on kinematic nonholonomic systems. However, an increasing body of research points to benefits that dynamic components of these systems, such as underactuated degrees of freedom, can provide.

This work investigates the effect of adding stiff degrees of freedom to the Chaplygin sleigh, a classical nonholonomic system that has been used in the past as a swimming model. Observed resonance behavior is shown to …

Chronic Effects Of Methylphenidate On Neuronal Viability And Plasticity, Hannah Oakes

Electronic Theses and Dissertations

Methylphenidate (MPH) is the most commonly prescribed drug to treat Attention Deficit Hyperactivity Disorder (ADHD). ADHD is now considered a life-long disorder; therefore, patients take MPH from adolescence into adulthood, highlighting the need for research studying chronic MPH use. MPH increases dopamine and norepinephrine within the synaptic cleft; therefore, chronic use of MPH may lead to changes within important dopaminergic pathways. One pathway, the mesolimbic pathway, includes the hippocampus, an area where adult neurogenesis occurs. We investigated the effects of chronic low and high doses of MPH on neurogenesis and examined levels of a few key proteins linked to cell …

Predator-Avoidance Of Larval Black-Bellied Salamanders (Desmognathus Quadramaculatus) In Response To Cues From Native And Nonnative Salmonids, Brian L. Dempsey

Electronic Theses and Dissertations

The introduction of nonnative salmonids into Southern Appalachia may pose a threat to resident salamander populations. In recent years, the stocking and encroachment of rainbow trout (Oncorhynchus mykiss) into headwaters where the black-bellied salamander (Desmognathus quadramaculatus) and brook trout (Salvelinus fontinalis) naturally coexist has raised concerns. In aquatic prey, predator-avoidance responses are primarily influenced through the detection of chemical cues released from predators. The objective of this study was to determine how co-occurrence with a predator influences black-bellied salamander predator recognition behavior. To evaluate this, salamander activity metrics (general activity, number of movements, and latency to move) were recorded before …
