Methodologies For Simplified Lifeline System Risk Assessments, Michael Germeraad

Master's Theses

Natural hazards are a growing risk across the globe. As regions have urbanized, single events impact greater proportions of the population, and the populations within those regions have become more dependent on infrastructure systems. Regional resilience has become closely tied to the performance of infrastructure. For a comprehensive risk assessment losses caused by lifeline outage must be considered alongside structural and nonstructural risks. Many well developed techniques quantify structural and nonstructural risk; however, there are insufficient procedures to determine the likelihood of lifeline outages. Including lifelines in seismic assessments will provide a comprehensive risk, improving a decision maker’s capacity to …

Prison-Based Animal Programs: A Descriptive Analysis, Alicia M. Loe

Master's Theses

There are many types of programs used in prisons. One such type is known as prison-based animal programs (PAPs). Prison-based animal programs bring animals into facilities in order to help offenders with emotional and behavioral problems. However promising these programs are, there is little empirical research. If these programs are to be continued, more research is needed. There has only been one national study looking at PAPs (Furst 2006). This current study will help fill the gap on PAP research. A national study was conducted using 302 randomly selected correctional facilities. Characteristics of PAPs were gathered through the use of …

Analysis Of Embryo Scoring And Comparison Of Clinic Performance In In-Vitro Fertilization, James W. Whistler

Master's Theses

Clinical Assisted Reproductive Technology (ART) practices seek to make improvements in embryo quality and resultant procedural success rates. There is a significant variance in live birth rates among clinics nationwide. The goal of this thesis is make comparisons of embryo quality among clinics and understand these differences. This analysis focuses on the stage between egg retrieval and embryo transfer. Because the currently accepted embryo scoring methods are not directly proportional to performance, a new scoring methodology is proposed and applied. Data provided by the Society for Assisted Reproductive Technology (SART) consisting of 36,836 patient cycles from 40 anonymous clinics nationwide …

Deciphering The Functional Collaboration Of Mid And Bric-A-Brac 2 As Potential Regulators Of Cellular Proliferation Within Adult Drosophila Ovaries, Petra Visic

Master's Theses

Stem cell niches are highly organized and specialized microenvironments located within specific tissues of both vertebrate and invertebrate organisms [1]. In Drosophila melanogaster, three distinct stem cell niches have been identified within the ovary including the germline stem cell (GSC), follicle stem cell (FSC), and escort stem cell (ESC) niche. Recently, Fregoso-Lomas et al. [2] reported that Gurken/Epidermal Growth Factor Receptor (EGFR) signaling is modulated within posterior ovarian follicle cells by Midline (Mid). The mid gene encodes a T-box transcription factor protein that specifies cell fates in the developing heart [3][4], central nervous system [5][6], epidermis [7], and eye …

Geographic Patterns Of Genetic Distribution Within Calochortus Gunnisonii In The Central And Southern Rocky Mountains, Ryan Scott Fuller

Master's Theses

Organismal population ranges and genetic architecture have largely been shaped by climatic events. The Quaternary Period (2.6 million years to present) has been characterized by a series of climatic events manifested as Ice Ages. During glacial periods, plants and animals in temperate and arctic regions were restricted to small patches of suitable habitat less affected by expanding glaciers and extreme cooling. These refugia held importance for the persistence of organisms through glacier interphases. Mountain system vegetation in temperate latitudes was affected by patchy glacier patterns that separated some species into multiple refugia. The isolation of such populations has had a …

Physical Disability And Suicidal Desire: An Examination Of The Constructs Of The Interpersonal-Psychological Theory Of Suicide, Lauren Rachel Khazem

Master's Theses

The primary aims of this study were to examine constructs of the Interpersonal-Psychological Theory of Suicide (IPTS) in an understudied population. Differences in levels of IPTS variables and suicidal ideation between university students with and without physical disabilities were examined. Participants were 184 students from two Southern universities who provided answers to online-based self-report questionnaires. It was hypothesized that students with physical disabilities would endorse higher levels of all IPTS constructs relative to students without physical disabilities. It was further hypothesized that disability status would exhibit an indirect effect on suicidal ideation through perceived burdensomeness and thwarted belongingness. Results indicated …

A Comparison Of Habitat And Geomorphic Changes On East Ship Versus Sand Islands Mississippi, 2007-2014, Carlton Peter Anderson

Master's Theses

ABSTRACT

A COMPARISON OF HABITAT AND GEOMORPHIC CHANGES ON EAST SHIP VERSUS SAND ISLANDS MISSISSIPPI, 2007-2014

by Carlton Peter Anderson

May 2015

The islands of the Mississippi-Alabama (MS-AL) barrier island chain along the micro-tidal northern Gulf of Mexico are highly dynamic coastal features subject to rapid changes in habitat, geomorphology, and elevation by natural and anthropogenic disturbances, such as hurricanes, subsidence, sea-level rise, and dredging activities. The purpose of this study was to compare elevation, total volume, habitat-type coverage, and short-term change between “naturally” formed East Ship Island and “man-made” Sand Island (Disposal-Area 10). This study used a combination of …

Personality, Character Strengths, Empathy, Familiarity And The Stigmatization Of Mental Illness, Jessica Shanna James

Master's Theses

The stigma associated with mental illness is pervasive and detrimental. The aim of the current study was to assess individual characteristics that may be positively and negatively associated with the stigmatization of mental illness. Two-hundred fifty-nine undergraduate students from the University of Southern Mississippi completed measures of the Big Five personality traits (i.e., Agreeableness, Extraversion, Conscientiousness, Neuroticism, and Openness to Experience), Dark Triad personality traits (i.e., Machiavellianism, Narcissism, and Psychopathy), selected character strengths (i.e., Open-mindedness, Perspective, Bravery, Integrity, Kindness, Social Intelligence, Fairness, Forgiveness and Mercy, and Hope), Empathy, and Familiarity with mental illness. Participants also completed measures of stigmatizing attitudes …

Are People Reading Local News? A Content Analysis Of Popular News Stories On Nine Newspaper Websites, Peter Shiang Chen

Master's Theses

The news industry has come under tremendous pressure in the last decade. None more so than the newspaper industry, which has seen all aspects of its operation: readership, revenue, staff, distribution and reputation decline dramatically. This study uses content analysis to examine the reading habits of news consumers from nine newspaper-based websites from the Advance Publishing chain. The samples were the stories in the “most popular this hour” list, examined every 5 days from August to September, 2014. These stories were separated into categories such as news, sports, business, etc., and further coded based on their proximity to the news …

A Study On Photodegradation And The Fate Of Pyrogenic Carbon, John Thomas Howell

Master's Theses

Accounting for all possible sources of atmospheric CO₂ is a pressing issue today due to the increasing effects of climate change. Estimates suggested that on the order of 1.3 million tons of dissolved pyrogenic carbon (pyDOC) could be entering the northern Gulf of Mexico annually. Assessing the fate of pyDOC in aquatic systems is crucial to understanding ecosystem impacts and potential feedback to climate change. Current research indicates that despite a generally lower susceptibility to biodegradation than their unpyrolyzed equivalents, pyrogenic carbon is not environmentally inert. While the role of microorganisms on the fate and transformation …

Excerpts From Television's Greatest Hits And Other Stories, Zachary Stephen Williams

Master's Theses

The short stories contained in this manuscript are mostly of the realist stripe, with a few concessions made to my more fabulist tendencies. Each is about men and women being forced to relive their old lives or finding themselves at the cusp of new ones, propositions which prove simultaneously attractive and repulsive. By the end of each story, it is my hope to transmit that the characters have survived somewhat intact, though reconstituted. There is a man in grief over the death of the wife he couldn’t stop cheating on, adults trick-or-treating at the expense of their children’s youths, a …

Fixing The Failed: An Investigation Of Terrorist Organizations And State Building Capabilities, Joshua Adam Freeman

Master's Theses

This study examines the role of terrorist organizations in failed states. In particular, their ability to perform positive state-building activities that result in stability is investigated. Both terrorism and state failure present unique and serious threats to international security. However, there is very little literature concerning the positive effect terrorist organizations can have in failed states. Presented is not only an investigation of the linkages between state failure and terrorism, but also a new classification of terrorist organizations based upon their ability to state-build in failed states. These organizations are classified by their ability to provide goods and services within …

Seasonal Variation In Corticosterone, Stress Responses, And Physiology In The Northern Cardinal Cardinalis Cardinalis, Benjamin Matthew Duckworth

Master's Theses

Seasonal regulation of the adrenocortical response (e.g., ‘stress response’) appears to be ubiquitous in mid- to high-latitude vertebrates. Northern Cardinals (Cardinalis cardinalis) are a Temperate dwelling passerine of Tropical-descent with a wide species range (tropics to Northern Temperate zones). This species encounters a wide variety of environmental conditions and strong seasonality, however corticosterone (CORT, the main adrenal stress hormone) has not been studied with regards to changes in seasonal levels. I initially analyzed samples from cardinals collected between 2007-2011 from the Lake Thoreau Environmental Research and Educational Center (Hattiesburg, Mississippi, USA). The data suggested seasonal differences of CORT, with higher …

Deepwater Horizon Impacts On The Diet, Growth, And Condition Of Larval Spanish Mackerel (Scomberomerus Maculatus), John Timothy Ransom

Master's Theses

The Deepwater Horizon oil spill (DWHOS) coincided with the pelagic larval stages of many valued commercial and recreational fishes in the northern Gulf of Mexico. Larval fish survival and eventual recruitment into adult populations may have been impacted by changes in the planktonic food web caused by the release of oil and chemical dispersants during the DWHOS event. Using samples from a long-term ichthyoplankton survey off the coast of Alabama, I sought to resolve the effects of the DWHOS on larval fishes. I compared the condition, growth, and diet of larval Spanish Mackerel (Scomberomorus maculatus), collected during summer …

Unsortable Wares: A Petrographic Analysis Of Addis Temper From The Fatherland Site (22ad501), Adams County, Mississippi, David Benjamin Abbott Jr.

Master's Theses

In the Lower Mississippi Valley from about 1200AD until European contact, two different ceramic tempers (and presumably cultures) existed side-by-side. Areas in which grog or clay tempering occurs are considered part of the Plaquemine Culture. Areas in which shell tempering predominates are considered part of the Mississippian Culture. Ceramic pastes that contain both shell and grog cause some classificatory confusion. This research examines the history of some of the confusion surrounding Addis ware/paste through its varying descriptions in the archaeological literature and attempts, through experiment and petrographic analysis, to give some insight into this paste recipe and its variability.

Age And Iq As Potential Moderators In The Relation Among Endopheonotypes And Expressed Behaviors In Children With Autism Spectrum Disorder, Elizabeth Clara Fair

Master's Theses

The current study examined how certain endophenotypes (i.e., local processing ability, mental flexibility, planning, and disinhibition /inhibition) are related to specific expressed behaviors (i.e., acting out behaviors, social insight deficits, social contact problems, anxious/rigid behaviors, and stereotypical behaviors) that are commonly found in children with ASD. In addition, this study examined whether these associations are modified by age or IQ. Participants consisted of 29 children (ages 7 to 16 years) with ASD and their parents. Parents completed the Children’s Social Behavior Questionnaire (CSBQ) to assess their child’s variety of expressed behaviors. The children were given the Kaufman Brief Intelligence Test—Second …

College Students’ Alcohol Use And Related Problems: What Makes Religiousness A Protective Factor?, Corey Todd Brawner

Master's Theses

Excessive alcohol use has been recognized as a critical health hazard for college students, particularly for members of social fraternities and sororities. Religiousness and Spirituality (R/S) has received substantial support as a protective factor for alcohol use across many populations. The current study utilized a series of hierarchical regression models to delineate the protective influences of six R/S dimensions on alcohol consumption, harmful drinking patterns, and alcohol-related problems, as well as their moderating effect on the association between Greek membership and alcohol outcomes in a sample of 709 undergraduates from one Christian-affiliated institution and one public university. Public religious participation …

Impacts Of The Deepwater Horizon Oil Spill On Microbial-Mediated Cellulose Decomposition In Mississippi Gulf Coast Salt Marshes, Jerrid Shawn Boyette

Master's Theses

Field studies were conducted to examine the effects of the Deepwater Horizon oil spill on rates of marsh organic matter decomposition. Decomposition in surface and subsurface marsh sediments was assessed in stands of Spartina alterniflora and Juncus roemerianus in 9 Mississippi Gulf Coast marshes exposed to differing oiling intensities. The cotton strip bioassay technique was used as a proxy for cellulose decomposition. In addition, rates of microbial respiration, fungal biomass (ergosterol) and nutrients (C:N, C:P) of surface sediment cotton strips were also quantified. Subsurface cotton strip decay, as determined by losses in tensile strength, were significantly different among marsh …

Marine Snow Settling Velocities At An Oil Spill Site And A Control Site In The Northern Gulf Of Mexico, Clayton Hugh Dike

Master's Theses

After budgeting for response efforts and natural processes, over one million barrels of oil from the BP oil spill were unaccounted for. A hypothesis coined "The Dirty Blizzard" formed subsequent to observations of large and numerous oiled marine snow aggregates amidst the surface slick proposed that a large quantity of oil sank to depth via the aggregates. Having reached the seafloor, aggregates were subject to microbial degradation and to redistribution due to bottom currents. To assist in characterizing redistribution of particles near the seafloor, sediment traps, marine snow cameras, and acoustic Doppler current profilers (ADCPs) were deployed at two sites …

Saving Sex Slaves: The A21 Campaign And The Mobilization Of Christian Affect, Nicole Elizabeth Magee

Master's Theses

In this thesis, I argue that the A21 Campaign’s discourse mobilizes Christian affect to produce relational proximity between audience members and human trafficking victims. My study intervenes in related literature surrounding Burke’s (1969) idea of identification by acknowledging that discourse can invite audiences to feel relationally close to or empathetic with others in the absence of consubstantiation. Relying on Gould’s (2009) notion of the mobilization of affect, I contend that unconscious, Christian affective investments are mobilized within A21’s rhetoric through the covert deployment of evangelical tropes that register with Christians’ affective desires and encourage believers to act as Christ or …

Humor Types: Replication Using Latent Profile Analysis And Associations With Maladaptive Personality Traits, Joseph Robert Finn

Master's Theses

Martin’s (2003) Humor Styles Questionnaire measures four distinct styles of humor usage. However, examining these humor styles individually fails to account for the combination with which they are used as well as how these combinations may affect the relationship between humor and personality. The present study examined relationships of the humor styles, both individually and in combination, with a broad array of maladaptive personality traits. The incremental validity of accounting for the combinations with which the humor styles are used was examined through the use of hierarchical multiple regressions. Results demonstrated that the humor styles, both individually and in combination, …

Eight Degree Of Freedom Vehicle Model With Pitch, Yaw, Tire Control And Sensor Inputs, Sean T. Hirtle

Master's Theses

This research focuses on the development of an eight degree of freedom vehicle model in the MATLAB computing language. Its purpose is to provide flexibility in the modeling and implementation of signal inputs and crash avoidance logic while maintaining accuracy in the physics of the vehicle’s motion. Firstly, the equations of motion for the bodies involved under a reasonable set of assumptions were developed. Next the model was translated to computer code. By writing the model in SimuLink with *.m files, the modularity of the code is enhanced. To validate the model, several well defined tests were simulated.

To establish …

Synthetic Aperture Radar: Rapid Detection Of Target Motion In Matlab, Daniel S. Kassen

Master's Theses

Synthetic Aperture Radar (SAR) has come into widespread use in several civilian and military applications. The focus of this paper is the military application of imaging point targets captured by an airborne SAR platform. Using the traditional SAR method of determining target motion by analyzing the difference between subsequent images takes a relatively large amount of processing resources. Using methods in this thesis, target motion can be estimated before even a single image is obtained, reducing the amount of time and power used by a significantly large amount. This thesis builds on work done by Brain Zaharri and David So. …

Experimental Investigation Of Drag Reduction By Trailing Edge Tabs On A Square Based Bluff Body In Ground Effect, Scott R. Sawyer

Master's Theses

This thesis presents an experimental investigation of drag reduction devices on a bluff body in ground effect. It has previously been shown that the addition of end-plate tabs to a rectangular based bluff body with an aspect ratio of 4 is effective in eliminating vortex shedding and reducing drag for low Reynolds number flows. In the present study a square based bluff body, both with and without tabs, will be tested under the same conditions, except this time operating within proximity to a ground plane in order to mimic the properties of bounded aerodynamics that would be present for a …

Evaluating The Effectiveness Of Cranial Molding For Treatment Of Positional Plagiocephaly Using Finite Element Analysis, Maziyar Keshtgar

Master's Theses

Since the advent of recommendations for placing infants in the supine position during sleep to reduce the incidence of sudden infant death syndrome, clinicians have noted an increase in the frequency of cranial asymmetry due to deformation of suture sections of the infants’ skulls as a result of constant concentrated stress in one area at the back of their head. This specific form of cranial deformation is known as positional plagiocephaly and its rate of occurrence has increased from 0.3% in 8.2% within the past 30 years.

Current treatments and methodologies for preventing and correcting positional plagiocephaly such as stretching …

Master's Theses

In today's fast-paced, fiercely competitive world; speed and flexibility are essential. Companies are increasingly realizing that the sequential approach to developing new product simply will not get the job done.

The goal of this thesis is to investigate critical issues and challenges that occur during the transition from a traditional software development methodology such as Waterfall to Scrum. During the last decade, Scrum has gained a vast success in software development due to its lightweight character and efficient way of handling the challenges of increased market speed, change and product complexity.

This thesis is based on a sequential exploratory mixed …

The Self-(Un)Made Mother: Jungian Archetypes In Dickens's Little Dorrit, William David Love Jr.

Master's Theses

Charles Dickens’s novel Little Dorrit (1857) depicts an abundance of surrogate mothers while simultaneously revealing an absence of biological motherhood. The primary female characters become surrogate mothers in their own ways in order to bypass the legal and physical dangers associated with biological motherhood. To do this, they embrace various alternate forms of femininity—the crone, the maiden, the woman warrior, and the seductress. These women negate themselves willingly in actions that would seem to reinforce the gender norms of their time, but their self-negation actually leads to empowerment and sustainability for themselves and for others. Furthermore, a Jungian interpretation of …

A Settlement Geography Of Three Ports On The Northern Gulf Of Mexico: The Role Of Rivers, Railroads, And Hurricanes: 1830-1930, Zachary Evan Kalina

Master's Theses

The settlement geography of the Gulf Coast of the United States possesses and shares unique cultural and historical characteristics. The thesis analyzes three selected towns along the coast: Indianola, Texas; Pascagoula, Mississippi; and Apalachicola, Florida. The thesis focuses on describing each town’s historical background and early efforts at permanent settlement, the expansion of the settlement using various modes of transportation such as shipping and railroads, the economic and agricultural base that was used to improve the settlement’s reputation, the characteristics of the settlement’s concept of folk housing, and the impact and recovery of the settlement from disasters such as fire …

Another Word For Autumn And Other Stories, Henry Burgard Shepard Iii

Master's Theses

The subject, style, and form of these stories are different from one another. At first glance, there seems to be no obvious thematic connection throughout this collection, no binding thread that ties them together. However, what allows these stories to exist side by side is their focus. The characters in these stories are human, no matter what situation they find themselves in, be it strange, fantastic, or mundane, they strive to achieve their desires. Each story takes a different approach to create a succinct feeling, all parts working toward eliciting a certain emotion. In one story, a family is powerless …
