Maternal Effects And Offspring Behavior: Potential Contributors To The Lack Of Recruitment In Mississippi Gopher Tortoises (Gopherus Polyphemus), Aaron L. Holbrook Dec 2015

Maternal Effects And Offspring Behavior: Potential Contributors To The Lack Of Recruitment In Mississippi Gopher Tortoises (Gopherus Polyphemus), Aaron L. Holbrook

Master's Theses

Federally threatened in Mississippi, gopher tortoise (Gopherus polyphemus) populations within the state have strongly variable recruitment and are generally in decline. Hatching success is significantly lower in Mississippi than in any other part of the species’ range , and most hatchlings die within the first year. There are few refuges where survival and hatching success is high. Here I compare two populations that differ in recruitment and offspring survival for differences in corticosterone. Corticosterone is a hormone that influences both energy availability and is released in elevated levels during stressful events, like living in poor quality habitat. Prolonged corticosterone elevation …

A previous study found that the majority of the Hispanic American population felt as if they are overlooked and would not be warned properly in a time of crisis (Heath, Lee, & Ni, 2009). Therefore, the present study focused on variables …


High Resolution Melt Analysis Of Samples With Differential Dna Methylation To Identify Tissue Source Of Origin, Stephanie M. Ledgerwood Dec 2015

High Resolution Melt Analysis Of Samples With Differential Dna Methylation To Identify Tissue Source Of Origin, Stephanie M. Ledgerwood

Master's Theses

In Forensic Science casework, identifying the source of a tissue can assist in crime scene reconstruction. Currently, presumptive testing methods to identify tissue type are utilized in crime scene laboratories, but there is a need for a more reliable confirmatory test for tissue type identification. High Resolution Melt (HRM) analysis is an innovative technology that has the potential to determine tissue types through variations in DNA methylation patterns. Recently, DNA methylation patterns have been found to correspond with specific tissue types in particular regions of DNA. Two markers, B_SPTB_03 and DDX4 have been effective in differentiating sperm from other tissue …


A Statistical Model For The Prediction Of Dissolved Oxygen Dynamics And The Potential For Hypoxia In The Mississippi Sound And Bight, Andreas Moshogianis Dec 2015

A Statistical Model For The Prediction Of Dissolved Oxygen Dynamics And The Potential For Hypoxia In The Mississippi Sound And Bight, Andreas Moshogianis

Master's Theses

Hypoxia events occur when dissolved oxygen concentrations fall below the minimum threshold (dissolved oxygen concentrations < 2 mg O2 L-1) necessary to avoid respiratory distress among aquatic organisms. In the Mississippi Sound and Bight, hypoxia is most prevalent from late-spring through late summer. Since hypoxia events can have dramatic effects on coastal fisheries, the spatial and temporal magnitude of hypoxia presents a clear threat to the productive fisheries in the northern Gulf of Mexico. Long-term hydrographic data were collected from eight sampling stations on a monthly basis from January 2009 to December 2011 along a cross-shelf transect from the mouth of …

Territorial Defense Strategies In The Northern Cardinal (Cardinalis Cardinalis): Who Is The Bigger Threat?, Kaylee M. Gentry

Master's Theses

This thesis examines the use of defensive strategies in relation to territories year round in the northern cardinal (Cardinalis cardinalis). Responses to recorded neighbor song and stranger song playback from the middle of a focal male’s territory were measured. This allowed for an estimation of aggression in both the winter and spring seasons. Each focal male was subjected to both treatments (stranger song and neighbor song). Males were more responsive over-all to neighbor song playback, however in the winter months, persistence of response to neighbor song playback increased. It was also shown that southeastern United States cardinals show …


Child Routines And Self-Regulation As Mediators Of Parenting Practices And Externalizing Problems In Preschoolers, Lovina R. Bater Dec 2015

Child Routines And Self-Regulation As Mediators Of Parenting Practices And Externalizing Problems In Preschoolers, Lovina R. Bater

Master's Theses

Studies clearly indicate that parenting practices relate to child externalizing behaviors, although the mechanisms underlying this relation are less well understood. Researchers suggest that daily routines are one way through which parenting practices relate to externalizing behaviors, allowing children to regulate their thoughts, emotions, and behaviors accordingly, potentially promoting development of appropriate self-regulatory behaviors. Self-regulation is also a possible route through which child routines inversely relate to externalizing behaviors. These relationships have been tested in school-age and older children, yet self-regulatory abilities are known to develop during the preschool period. This study examined child routines and self-regulation as serial mediators …

Democratizing Dionysus: The Origins Controversy And The Dual Evolution Of Tragedy And Civism, Belen Plaza-Gainza Dec 2015

Democratizing Dionysus: The Origins Controversy And The Dual Evolution Of Tragedy And Civism, Belen Plaza-Gainza

Honors Theses

Finding the origins of tragedy has been a fascinating subject since late antiquity, and it continues to be a source of academic debate. The controversy I have examined is from the early years of our twenty-first century, and has questioned the testimony of Aristotle, opening the debate once again. The evidence continues to prove that tragedy’s origins were religious, and even though there is no hard evidence to prove that it evolved from Dionysiac ritual, there is no hard evidence to disprove this theory either.

I have taken this opportunity to examine the origins of tragedy from its evolution, which …


Influence Of Benagene Supplementation In Conjunction With High Intensity Cycling Exercise, Wilson P. Simmons Dec 2015

Influence Of Benagene Supplementation In Conjunction With High Intensity Cycling Exercise, Wilson P. Simmons

Honors Theses

High intensity aerobic performance is determined by the body’s maximal ability to match lactate production and clearance rates, defined as the lactate threshold (LaTh). Intensities performed above the LaTh result in accumulation of lactate causing fatigue. In a double-blind experiment, using trained cyclists and triathletes, we investigated skeletal muscle adaptations that occurred following 28-days of Benagene supplementation (oxaloacetate). The testing protocol consisted of an initial cycle test (T1) to measure VO2max, LaTh, respiratory exchange ratio (RER), power output (PO) and heart rate (HR). Testing began after a 15-min warm-up at 75W, beginning at 100W, increasing 30W each 3-min …


¿Dónde Están Todas Las Mujeres?: The Impact Of Female Labor Force Participation On Female Political Representation In Latin America, Murakami A. Carpenter Dec 2015

¿Dónde Están Todas Las Mujeres?: The Impact Of Female Labor Force Participation On Female Political Representation In Latin America, Murakami A. Carpenter

Honors Theses

Do higher levels of female labor force participation increase female political representation? Over the past 40 years, the involvement of Latina women in the labor force and the number of female legislators in Latin America has been steadily increasing. To determine if there is a correlation between these two variables, this research builds on the socio-economic status model created by Brady, Verba and Schlozman (1995). Using both a bivariate and a multivariate model, I test for a correlation between the number of women working and the number of elected female legislators in 24 Latin American countries. Contrary to expectations, I …

Characterization Of Embryonic Stem Cell-Differentiated Cells As Mesenchymal Stem Cells, Rachael N. Kuehn Dec 2015

Characterization Of Embryonic Stem Cell-Differentiated Cells As Mesenchymal Stem Cells, Rachael N. Kuehn

Honors Theses

Embryonic stem cells (ESCs), due to their ability to differentiate into different cell types while still maintaining a high proliferation capacity, have been considered as a potential cell source in regenerative medicine. However, current ESC differentiation methods are low yielding and create heterogeneous cell populations. If transplanted in the human body, differentiated ESCs could be rejected by the immune system, form tumors, or may not function normally within the human body. On the other hand, mesenchymal stem cells (MSCs), a type of adult stem cell typically derived from bone marrow, have proved to be excellent candidates in clinical applications due …


Robert Frost’S New Hampshire, Philip Larkin’S England, And Seamus Heaney’S Ireland: Non-Urban Place And Democratic Poetry, Faisal I. Rawashdeh Dec 2015

Robert Frost’S New Hampshire, Philip Larkin’S England, And Seamus Heaney’S Ireland: Non-Urban Place And Democratic Poetry, Faisal I. Rawashdeh

Dissertations

In Anglo-American Modernist poetry, place is reduced to an analogue for the cultural degradation brought forth by the disruptive experience of modernity. This demotion stands in sharp contrast to the representation of place as a center of value in the poetry of Robert Frost, Philip Larkin, and Seamus Heaney. In this dissertation, I shall explain this value in terms of its connection to a particular cultural substance which Frost, Larkin, and Heaney deem foundational for their non-ideological terms of belonging to place. Frost embraces New England vernacularism first as the basis for his egalitarianism and second as the core substance …

Polyacrylonitrile Copolymers: Effects Of Molecular Weight, Polydispersity, Composition, And Sequencing On Thermal Ring-Closing Stabilization, Jeremy D. Moskowitz

Dissertations

Controlled polyacrylonitrile (PAN)-based carbon fiber precursors with defined molecular weights, polydispersities, compositions, and architectures have been prepared for their study on thermal ring-closing stabilization behavior. PAN and its copolymers of number average molecular weights exceeding 170,000 g/mol were successfully synthesized via low temperature reversible addition-fragmentation chain transfer (RAFT) polymerization. RAFT polymerizations of PAN-based precursors were compared to conventional free radical solution polymerizations with a focus on the effects of molecular weight and polydispersity on structural evolution and cyclization efficiency. When RAFT polymerization was extended to copolymers, it was found that RAFT copolymers achieved greater cyclization intensities and improved thermal stability …


Mississippi Teachers’ Perception Of Merit Pay, Diana M. Stephens Dec 2015

Mississippi Teachers’ Perception Of Merit Pay, Diana M. Stephens

Dissertations

Teachers are the center of increasing student achievement and student motivation, therefore a way to motivate teachers must be implemented. Although most teachers are motivated intrinsically for their love of teaching, external motivation could add another component to teacher success. Merit pay is one way to provide an external motivator to change teaching strategies in order to increase student achievement. This study measured teachers’ perceptions in Mississippi who are involved in the merit pay pilot program. There are four school districts participating in the pilot program and two of those school districts were surveyed for this study, a central Mississippi …

Olfactory Enrichment In California Sea Lions (Zalophus Californianus), Mystera M. Samuelson

Dissertations

In the wild, California sea lions (Zalophus californianus) are exposed to a wide array of sensory information at all times. However, it is impossible for captive environments to provide this level of complexity. Therefore unique procedures and practices are necessary for the maintenance of physiological and psychological health in captive animals (Wells, 2009). This project aims to explore the behavioral effect of scent added to the environment, with the goal of improving the welfare of captive sea lions by introducing two scent types: 1.) Natural scents, found in their native environment, and 2.) Non-natural scents, not found in …


Macrobenthic Communities In The Northern Gulf Of Mexico Hypoxic Zone: Testing The Pearson-Rosenberg Model, Shivakumar Shivarudrappa Dec 2015

Macrobenthic Communities In The Northern Gulf Of Mexico Hypoxic Zone: Testing The Pearson-Rosenberg Model, Shivakumar Shivarudrappa

Dissertations

The Pearson and Rosenberg (P-R) conceptual model of macrobenthic succession was used to assess the impact of hypoxia (dissolved oxygen [DO] ≤ 2 mg/L) on the macrobenthic community on the continental shelf of northern Gulf of Mexico for the first time. The model uses a stress-response relationship between environmental parameters and the macrobenthic community to determine the ecological condition of the benthic habitat. The ecological significance of dissolved oxygen in a benthic habitat is well understood. In addition, the annual recurrence of bottom-water hypoxia on the Louisiana/Texas shelf during summer months is well documented.

The P-R model illustrates the decreasing …

How Did The Students Cross The Stage? The Relationship Of Demographic Factors On Early Selection Of College Major, Christy Riddle Dec 2015

How Did The Students Cross The Stage? The Relationship Of Demographic Factors On Early Selection Of College Major, Christy Riddle

Dissertations

Student retention is a highly researched topic studied for many decades, but low retention of college students still exists today. As more states move to success-based funding formulas, it is more important than ever for higher education institutions to increase retention efforts (Swecker, 2011). Colleges and universities launch programs trying to combat and improve retention deficits. Research reveals that student engagement, academic advising, demographics, socioeconomic factors, and early selection of major within the first academic year play a role in retention.

The purpose of this study is to determine if early selection of major relates to the demographic factors of …
