Molecular Detection Of Tick-Borne Pathogens Associated With Ixodid Tick Species Infesting Migratory Songbirds And Ruminants, Nabanita Mukherjee

Master's Theses

Ticks are hematophagous arthropods and capable of inoculating various infectious agents to their vertebrate hosts. Ticks attached to birds and ruminants are capable of carrying tick-transmitted microorganisms. In our study, the prevalence of tick-borne pathogens was examined in ticks infesting migratory songbirds and Pakistani ruminants. During spring migration seasons, ticks were removed from northward-migrating songbirds in Louisiana and identified as Amblyomma Jongirostre, Amblyomma nodosum, Amb/yomma ca/caratum, Amblyomma maculatum, and Haemaphysalis species, all are considered as Neotropical ticks. Ticks removed from ruminants were identified as Hya/omma anatolicum, Hyalomma dromedarii, Rhipicephalus microplus, and Rhipicephalus sanguineus. A total of 112 and 72 bacterial …

Lincoln: Reformer Or Revolutionary? An Analysis Of Lincoln's Legacy As Compared To The Political Ideals Of The Amerian Revolution, Hayley Elizabeth Patterson

Master's Theses

Despite the fact that his greatest legacies departed from American traditions, Abraham Lincoln coveted the political ideals espoused by the Founding Fathers. As president, Lincoln inherited the unprecedented challenges that resulted from decades of politicians tabling the insoluble problem of slavery. He operated within the realms of constitutionally allocated authority to meet those challenges. Where the Constitution provided no direction, Lincoln developed solutions that more closely resembled the political philosophies of the American Revolution than any of his political opponents' alternative solutions. The unprecedented circumstances he faced not only enabled Lincoln to reconcile the right to freedom as described in …

Adolescent Narcissism And Prosocial Behavior As A Function Of Peer, Parent, And Self-Perception, Rebecca Lynn Kauten

Master's Theses

The association between narcissism and aggression has been empirically supported in adults and adolescents, but it is unclear whether narcissism might also be related to prosocial behavior. The current study aimed to investigate different facets of narcissism in adolescents and their association with self-, parent-, and peer-reported prosocial behavior. In a sample of 175 at-risk adolescents ages 16-18 (151 males, 24 females), it was expected that reports of the individual's engagement in prosocial behavior would vary as a function of the informant and the specific facet of narcissism (i.e., adaptive or pathological). However, no main effects or interactions emerged with …

Do Gender, Delinquent Peer Affiliations, And Parenting Practices Moderate The Relation Between Callou-Unemotional Traits And Delinquency, Nicole Rivera-Hudson

Master's Theses

The present study examined how contextual factors differentially influence the relation between the components of callous-unemotional (CU) traits and delinquency for male and female adolescents. More specifically, it considered delinquent peer affiliations and ineffective parenting practices as moderators in this relation with the belief that those moderators would exert a different influence for males and females. The study was conducted with a sample of 238 adolescents (166 males, 72 females) ages 16 to 19 attending a voluntary military style residential program. Analyses demonstrated a general lack of support for the central hypotheses of the present study. There was a significant …

Development Of A Genetic Monitoring Program For Stock Enhancement Of Mississippi Spotted Seatrout (Cynoscion Nebulosus), Carly Renee Somerset

Master's Theses

The spotted seatrout is a coastal sciaenid fish that is intensively exploited in the northcentral Gulf of Mexico. A stock enhancement research program was initiated in 2004 to develop methods to culture juveniles and release them in natural habitats to increase recruitment in the fishery. The goal of this study was to initiate a genetic monitoring program for stock enhancement activities. Assays for 15 microsatellite loci were optimized. Simulations indicated that this panel of molecular markers was sufficient to identify recaptured hatchery fish with high confidence assuming genetic data on broodfish spawned to produce released fish were available. Stock structure …

Comparative Analysis Of Antiviral Responses In Mouse Embryonic Stem Cells And In Mesenchymal Stem Cells, Jundi Wang

Master's Theses

Embryonic stem cells (ESCs) are cells that have unlimited capacity for selfrenewal and differentiation. These properties make ESCs a great cell source for application in regenerative medicine. When used for cell therapy, ESC-derived cells could be placed in a wounded area that is likely to be exposed to various pathogens. However, it is not well-understood whether ESCs and ESC-derived cells have active antiviral responses against infectious agents from the environment. To answer this important question, I comparatively analyzed the antiviral responses of ESCs and mesenchymal stem cells (MSCs, C3H10Tl/2 cell line) to infectious agents. Using the expression of type I …

Spring Landbird Migration Along The Northern Coast Of The Gulf Of Mexico: Multi-Scaled Investigation Of Stopover Ecology Within An Urbanized Landscape, Jill Marie Gautreaux

Master's Theses

Two-thirds of bird species breeding in eastern N. America annually migrate from temperate breeding grounds to tropical wintering locations, engaging in non-stop movement directly across the Gulf of Mexico (GOM). Thus, millions of migrants concentrate in woodlands along the northern Gulf coast during spring and fall passage. These coastal landscapes are some of the most rapidly developing areas in the U.S. with population growth rates five times higher than that of inland areas. Anthropogenic pressures, along with human-created (e.g., oil spills) and natural disturbances (e.g., hurricanes), result in rapid degradation of sensitive coastal ecosystems, creating tension between importance of coastal …

Religious Fundamentalism And Death Penalty Attitudes: Towards A New Operationalization Of The Constructs, William H. Whited

Master's Theses

The death penalty has remained a highly debated topic in the United States. Due to the link between public support for the death penalty and its utilization as a sanction, it is important to continue investigating the factors related to differences in death penalty support. Religion has a complicated relationship with death penalty attitudes in that certain religiosity factors are associated with support for the sanction while others are linked with opposition. Religious fundamentalism, for instance, is one variable that has been inconsistently associated with death penalty support in the literature. This discrepancy could be due to the poor measurement …

Finite Element Analysis And Validation Of Hip Joints With The Main Types Of Femoroacetabular Impingement, Kevin Lucas Mitchell

Master's Theses

Current research suggests that femoroacetabular impingement can be a cause of osteoarthritis. Femoroacetabular impingement is a condition that can affect both the femur and the pelvis of an individual. Femoroacetabular impingement can cause damage to the hip joint and its surrounding tissues. The articular cartilage and the labrum are both affected by this condition. A cam impingement is where a bony protrusion develops at the femoral head/neck junction. A pincer impingement is where a bony protrusion develops at the acetabular rim. Often, patients are seen with a combination of both impingements. The main goal of this study was to computationally …

They have also questioned the experts that analyze fingerprints and the methods they use. There have been recent cases where judges have questioned the foundation of fingerprinting and dismissed fingerprints as evidence. This meta-analytic study brings together opinions, cases, and studies that focus on the foundation, evolution, and technological advancements of fingerprinting.

Analysis Of Post-Cranial Traits For The Assessment Of Biological Distance Among Temporally Distinct New World Populations Of African Descent, Claire Marie Dansereau

Master's Theses

This investigation examines change in post-cranial osteometric markers in temporally distinct New World populations of African ancestry: Newton Plantation series (17th-19th century Barbados; N = 16); two subsamples from the Hamann-Todd (HT) series (U.S.) based on birth year, 1865-1900 (N = 66) and 1901-1915 (N = 62); and the Forensic Databank Collection (FDB) (20th century U.S.; N = 137). It was anticipated that individuals from Newton would exhibit less admixture than those from H-T or FDB. They were also predicted to demonstrate greater skeletal robusticity due to mechanical loading. Additionally, it was expected that stature would increase over time due …

The Limitations Of Democratic Peace, Anthony Glenn Jordan

Master's Theses

The theory of Democratic Peace suggests that democracies are unlikely to wage war on one another, yet it spends little time actually defining what democracies are. Research on the theory of Democratic Peace suggests that the theory only applies to mature democracies, but how is maturity determined? The criteria used by multiple scholars is needed to defend the theory from particular challenges such as the Cenepa Valley War, but even with such defenses, the criteria omits how a state treats women and racial minorities. These omissions become clear when one examines how scholars treat the United States of America. This …

From Servitude To Freedom: Gender, Labor, And Domestic Relations, Elizabeth Michelle Talbot

Master's Theses

In the sugar parishes of Louisiana, enslaved people endured high mortality rates and declining populations at the height of the harsh slave regime in the mid-twentieth century. This resulted from regional disease, brutal working conditions, and a skewed sex ratio where enslaved men consistently outnumbered enslaved women. Following emancipation, freedwomen attempted to rebuild their families and community amid the tumultuous environment that defined the sugar parishes. This thesis utilizes Freedmen's Bureau records, American Missionary Association correspondence, census data, and local newspapers to argue that freedwomen sought to gain control over their labor, bodies, relationships, and children in the postbellum era …

Risk Assessment Model For Pipe Rehabilitation And Replacement In A Water Distribution System, Jan C. Devera

Master's Theses

The efficient delivery of potable water for a community through its distribution system has historically been the backbone of nearly all metropolitan developments. Much of these systems are comprised of pipe networks made of various materials including concrete, iron, PVC, and even steel. As these communities expand and urbanize, water demand and population density simultaneously increase. This develops higher strains and stresses in the community‟s water distribution network causing pipes to corrode, crack, or rupture prematurely while in service. As a result, the deterioration of water distribution systems in growing cities is increasingly becoming a major concern for our nation. …

The Effects Of Variation In Collagen D-Spacing On Compact Bone Viscoelasticity: A Finite Element Analysis, Miguel A. Mendoza

Master's Theses

The D-spacing that is characteristic of collagen and its structural arrangement was previously thought to be a constant value. Much research is revealing that it is actually a distribution of values in biological tissues. Recent ovine experimentation has also shown that the D-spacing distribution is significantly altered following estrogen depletion. While ewes contain some major biological differences between their human counterparts, they are an economical and robust large animal model for postmenopausal osteoporosis. So, the exploration of the possible implications that D-spacing has on the mechanical properties of the whole bone utilizing animal models and computational methods is warranted. Six …

A Study Of The Collisional Evolution Of Orbital Debris In Geopotential Wells And Geo Disposal Orbits, Christina R. Diaz

Master's Theses

This thesis will present the effects of the orbital debris evolution in two key areas: the geosynchronous disposal orbit regime known as “graveyard” and the two geopotential wells found in 105◦ W and 75◦ E longitude bins. After developing a GEO specific orbit propagator for NASA Johnson Space Center’s Orbital Debris Of- fice, collisions were simulated throughout these regimes using a low velocity breakup model. This model considered the effects of perturbations particularly non-spherical Earth effects (specifically sectorial and zonal harmonics), lunar effects, third body effects and solar radiation pressure effects. The results show that CDPROP does well in simulating …

An Insight Into The Microbial Diversity And Expression Of Cysteine Protease Inhibitors (Cystatin) In Rickettsia Parkeri Infected Amblyomma Maculatum, Khemraj Budachetri

Master's Theses

Amblyomma maculatum (Gulf Coast tick) is an emerging tick species of public health significance in United States. It is a competent vector of Rickettsia parkeri, an etiological agent of a human rickettsiosis. In this study, we investigated the spotted fever group of rickettsial diversity in A. maculatum based on rickettsial ompA gene PCR. Our results showed A. maculatum harbors R. parkeri, R. amblyommii, and R. endosymbiont of A. maculatum. While only R. parkeri was detected in female salivary glands which suggest its ability to traffic from midgut to salivary glands via hemocoel. The presence of R. parkeri was further …

The Development And Use Of A Color Discrimination T-Maze Learning Task In The Zebrafish (Danio Rerio), Elizabeth Ann Lamb

Master's Theses

Zebrafish (Danio rerio) are becoming increasingly utilized in behavioral studies as a model of human learning and memory. The results of a previous study by Colwill, Raymond, Ferreira, and Escudero (2005) indicated that this species is capable of discriminating between colors and learning to respond to an assigned hue at either arm of a T-maze, indicating a learned association between the neutral stimulus and reward. While this original study showed that this task was appropriate for use in this species, we proposed that it had the potential to provide more data on specifics of the learning process with amended methods. …

Stravinsky As Art And Entertainment: Performances Of His Music In The United States, 1910 - 1916, Penny R. S. Brandt

Master's Theses

Stravinsky's music was introduced into the United States in a variety of ways throughout the 1910s: in newspapers, through early concert performances of both absolute and program music, and through performances of his ballets by the Ballet Russes and by American ensembles. This study examines the different ways in which Stravinsky's music became known to the American public between 1910 and 1917 and includes information about early performances of his music in New York and Boston, including a production of Petrushka by the Neighborhood Players of New York in April 1916, and a parody of Rite of Spring penned by …

Historical Consciousness In Purcell's Canonic Settings Of The Lesser Doxology, Martha H. Brundage

Master's Theses

In an article on canon composition in England, Denis Collins noted similarities in the canonic styles of William Byrd and Henry Purcell. This project is an attempt to continue Collins’s research and identify similarities in the canonic writing of the sacred canons composed by Purcell and the earlier generation of Byrd and Thomas Tallis. There is evidence in Purcell’s canons that he drew inspiration from Byrd’s works.

Perhaps the most telling connection between the works of Byrd and Purcell is the similarity between Byrd’s canonic setting of the Gloria Patri as the third section of the motet O lux beata …

Improving The Surface-Ground Water Interactions In The Community Land Model: Case Study In The Blue Nile Basin, Di Wu

Master's Theses

Soil moisture is a key water cycle parameter, known to have a positive feedback on precipitation, namely, an increase in soil moisture would increase net radiation and latent heat flux and decrease sensible heat flux and consequentially lower the boundary layer height and increase moist static energy, which eventually leads to precipitation increase. Arguably, land surface models that simulate land surface processes and the surface fluxes to the atmosphere do not capture adequately the spatial variability of soil moisture, particularly over land surface areas with complex topography. A parameterization is applied in this study to the Community Land Model (CLM) …
