The Viral Fingerprint: A Content Analysis Of Popular Viral Advertisements, Thomas Grant Broadus Ii

Master's Theses

This paper presents an analysis of 280 online videos that appeared on the Advertising Age weekly chart of the top ten viral videos of the week; the videos appeared on the chart from March 23rd 2009 to March 9th 2011. The videos were analyzed along four areas of observation including the advertiser characteristics, the formatting characteristics of the video, the messaging strategies of each video, and the level of involvement the product would require for a consumer to make a purchase. Through examining the components of each video, a thread of commonality was revealed. Cumulatively, the dominant themes and characteristics …

Individual Differences In Zebrafish (Danio Rerio) Behavior: Implications For Personality, Christina Nicole Toms

Master's Theses

Individual differences (IDs) in zebrafish (Danio rerio) behavior were examined across time and contexts in order to investigate personality traits. Zebrafish (N = 30) were exposed to six behavioral tasks that were collectively expected to capture (a) aggression, (b) boldness/shyness, and (c) fear. The tasks included a small open field, mirror exposure, emergence, large open field, novel object, and predator exposure tasks. IDs in behavior were found to be consistent across time for a majority of behaviors and consistent across contexts for all but two behaviors. Convergent and discriminate evidence was examined for the three constructs. There was …

A Statistical Examination Of Friction Ridge Skin Patterns In The Interdigital, Hypothenar, And Thenar Areas Of The Palms, Kristin Ann Pilgrim

Master's Theses

Friction ridge skin, which is only located on the fingers, palms, and soles of the feet, has been used in the identification of individuals before the beginning of the twentieth century. A majority of the information known about friction ridge skin has been accumulated through the extensive research of fingerprints. Studies have been conducted to statistically categorize general patterns located on the fingerprints in order to include or exclude an individual for identification purposes. Although fingerprints offer great insight into the importance of friction ridge skin in forensic science, palm print patterns and characteristics have been relatively ignored. Therefore, a …

Mycorrhizal Colonization Of Native Salt Marsh Plants On Mississippi's Gulf Coast And The Effects Of Commercial Mycorrhizal Inoculants On Nursery-Grown Plants, Kathryn Rondot Mcbride

Master's Theses

Salt marshes are important economically and ecologically to the Gulf Coast and other coasts worldwide. Due to human activities, many coastal salt marshes have been degraded or destroyed. Restoration efforts, through the replacement or addition of naturally occurring salt marsh plants, are taking place worldwide. Most restoration plants are raised in nurseries and are not ready for transfer to restoration sites for eight or nine months. Once the plants are at the restoration site many die due to transplant stress. Arbuscular Mycorrhizal Fungi (AMF) may be able to shorten the time the restoration plants need to stay in the nursery …

Temporal And Spatial Variability Of Phytoplankton Biomass In Coastal Mississippi Waters, Lorin Matthew Dornback

Master's Theses

Chlorophyll concentrations were measured in western Mississippi coastal waters to determine the spatial and temporal variability of phytoplankton. Nutrients (nitrate, silicate, phosphate), river discharge, temperature, salinity, stratification, tides, currents and winds were measured in concert with the phytoplankton concentrations. The purpose of this study was to determine the seasonal variability in phytoplankton and what was driving the variability. This study was comprised of a three year (September 2007-November 2010) time series where samples were taken once a month for eight stations. Profiles of each station were taken using a Conductivity, Temperature and Depth (CTD) sensor and a WET Labs FL-3 …

An Examination Of The Yang-Baxter Equation, Alexandru Cibotarica

Master's Theses

The Yang-Baxter equation has been extensively studied due to its application in numerous fields of mathematics and physics. This thesis sets out to analyze the equation from the viewpoint of the algebraic product of matrices, i.e., the composition of linear maps, with the intent of characterizing the solutions of the Yang-Baxter equation.

We begin by examining the simple case of 22 matrices where it is possible to fully characterize the solutions. We connect the Yang-Baxter equation to the Cecioni-Frobenius Theorem and focus on obtaining solutions to the Yang-Baxter equation for special matrices where solutions are more easily found. Finally, …

The Use Of Remote Sensing For Mapping Possible Vectors Of West Nile Virus In Mississippi, Brian Matthew Moore

Master's Theses

There is renewed interest in disease surveillance due to the persistence of numerous vector-borne diseases. Though the life-history processes of disease vectors are known to dictate their distribution patterns, it has been hypothesized that vectors, such as local mosquito abundance, could be predicted from factors such as climate and land use/land cover. Remote sensing has been used as a supplement to traditional methods of mosquito surveillance and to map the spatial distribution of mosquito habitats. This, in turn, affords optimism for improved vector/disease management to identify the best use of remote sensing data and geo-statistical techniques to predict and map …

Transmitting Whiteness: Librarians, Children, And Race, 1900-1930s, Shane Hand

Master's Theses

In the wake of the public library movement in the southern United States during the early twentieth century, local librarians began providing library services for those whom they deemed to be their most valuable resources, children. Representatives of a new profession, children’s librarians campaigned for better tomorrows by collecting good books specifically for young readers while providing safe, comfortable spaces that encouraged an atmosphere of instructive entertainment.

Supplemental to the development of a unique children’s department, library administrators sought strong working relationships with the city’s various public schools. The public cooperative that developed between libraries and schools brought thousands of …

Feeding Selectivity And Habitat Usage Of Esox Americanus, Scott Richard Clark

Master's Theses

Patterns of piscine prey selection and habitat usage of Esox americanus were assessed through a series of field and experimental studies. Although few detailed studies exist on the foraging behavior and habitat usage of E. americanus, throughout its range it may be an important trophic component in maintaining fish assemblage structure in many lower order streams. Across 17 sampled streams, the presence of E. americanus among reaches within streams was found to be strongly correlated with increasing levels of habitat complexity. Reaches occupied by E. americanus featured increased amounts of in-stream physical structure, increased variability in stream width and …

Ornamentation, Behavior, And Maternal Effects In The Female Northern Cardinal, Caitlin Winters

Master's Theses

This study seeks to understand the relationship between ornamentation, maternal effects, and behavior in the female Northern Cardinal (Cardinalis cardinalis). Female birds possess ornaments that indicate a number of important known aspects of quality and are usually costly to maintain. However, the extent to which female specific traits, such as maternal effects, are indicated is less clear. It is predicted by the Good Parent Hypothesis that this information should be displayed through intraspecific signal communication. Specifically, androgens and carotenoids are of interest in this study because both are linked to ornamentation, and are also important egg components that …

The Relationship Of Testosterone And 5-Ht To Aggressive, Self-Aggressive, And Antisocial Behavior In Men, Anne Winston Mcintyre

Master's Theses

Studies of humans show an inconsistent relationship between aggression and T, as well as between T and antisocial and self-aggressive behavior. Other biological variables, including cortisol and brain serotonin, have been implicated as having an effect on the regulation of antisocial and self-aggressive behavior. Researchers have suggested that inconsistencies in the T-aggression relation may be due to the presence of moderating variables. One theory posits that serotonin moderates the relation between T and aggression. The purpose of this study was to examine the relationship between T (as well as cortisol and 5-HT) and aggression-related constructs. A second purpose was to …

An Extensionalist Approach To Ontological Commitment: Why Quine Is Mostly Right, William Felix Suttle Iii

Master's Theses

A criterion of ontological commitment is a formal method for determining what objects or entities a theory says exists. The most famous criterion of ontological commitment was developed by W.V.O. Quine. However, Quine's criterion has been attacked for presumably not meeting his own standards for an acceptable theory. After explaining the motivation and details of Quine's criterion, I will tum to the prominent objections against his theory. I will argue that there are problems both with Quine's formulation of his criterion, as well as the interpretation of Quine's criterion as presented by his objectors. In response to these issues, I …

Beneath The Surface: American Culture And Submarine Warfare In The Twentieth Century, Matthew Robert Mcgrew

Master's Theses

Cultural perceptions guided the American use of submarines during the twentieth century. Feared as an evil weapon during the First World War, guarded as a dirty secret during the Second World War, and heralded as the weapon of democracy during the Cold War, the American submarine story reveals the overwhelming influence of civilian culture over martial practices. The following study examines the roles that powerful political and military elites, newspaper editors and Hollywood executives, and ordinary citizens – equal players in a game larger than themselves – assumed throughout the evolution of submerged warfare from 1914 to 1991. In each …

A Comparison Of Two Different Methods For Solving Biharmonic Boundary Valve Problems, Megan Lashea Richardson

Master's Theses

We use the methods of compactly supported radial basis functions (CS-RBFs) and Delta-shaped basis functions (DBFs) to obtain the numerical solution of a two-dimensional biharmonic boundary value problem. The biharmonic equation is difficult to solve due to its existing fourth order derivatives, besides it requires more than one boundary conditions on the same part of the boundary. In this thesis, we use either a one-level or a two-level technique for constructing the approximate solution in the context of Kansa’s collocation method. This thesis will compare the accuracy of the methods of CS-RBFs and DBFs when applied to the biharmonic boundary …

The Application Of Personality Assessment To Suggest Appropriate Employment In Various Fields Within Economic Development, Brittani Elizabeth Plaisance

Master's Theses

Personality assessment has been established through previous literature as a viable tool in organizational contexts in different job fields (Hough & Dilchert, 2010; Rothstein & Goffin, 2006). The field of economic development has seen little application of personality assessment to aspiring professionals within the discipline. This research hoped to establish distinct personality typologies within economic development by bifurcating the field into two sectors of (a) business recruitment, retention, and expansion and (b) entrepreneurship developers and community developers. Participants were asked to complete the Personal Preferences Self-Description Questionnaire (Thompson, 1996) after distinguishing within which of the two realms they were employed. …

An Analytical Study Of Air-Sea Co2 Gas Exchange In The Northwest Mississippi Bight Region, Andrea Kathryn Braatz

Master's Theses

With the continued increase of carbon dioxide (CO2) emissions, researchers are concerned with accumulation of excess CO2 within the atmosphere. The ocean is an important sink for the drawdown of atmospheric CO2 concentrations. Due to high spatial and temporal variability, CO2 fluxes in the coastal ocean are not as well characterized as those for the open ocean. More specifically, data for the northern Gulf of Mexico (GOM) coastal region is lacking. A time series analysis of air-sea CO2 flux rates from May through December 2009 was conducted using data collected by The University of Southern Mississippi’s Central Gulf Ocean Observing …

Detection Of Hydrogen In A Two-Phase Cryogen Flow Stream With Thermal Protection Design Configurations, Anton Dmitrievitch Netchaev

Master's Theses

All commercial liquid-propelled rockets use hydrogen as means to reach outer space. These rocket boosters are tested on the ground and use hydrogen as means of purging the remaining explosive gasses left in the test tanks. To conserve helium, a non-renewable resource, a test fixture was developed to characterize and test sensors that could improve the accuracy and response of the current system. By improving response time of the system, helium waste during the purge process can be minimized. The test fixture was constructed to simulate temperatures and pressures that are encountered at the testing facilities. The test fixture is …

Diet And Feeding-Related Morphometrics Of The Blackstripe Topminnow, Fundulus Notatus, In Allotropic And Syntopic Populations With The Blackspotted Topminnow, Fundulus Olivaceus, Charles Michael Champagne

Master's Theses

The Fundulus notatus species complex consists of three described species: F. notatus, F. olivaceus and F. euryzonus. Both F. notatus and F. olivaceus have broad overlapping ranges with many populations being found within and outside of contact zones. Contact zones are generally found in midreaches with F. olivaceus dominating headwaters and F. notatus in larger rivers downstream. Both species share similar ecological niches so the mechanism allowing for stable coexistence in contact zones is unknown. The purpose of this study was to examine variability in diet and feeding morphology of F. notatus in syntopic and allotopic populations across …

Parenting A Chronically Ill Child: Social Support, Coping, Family Hardiness, And Maternal Stress, Kathryn Lynch Bigalke

Master's Theses

Parents of children with cancer experience higher stress than parents of children with other medical conditions or with no developmental concerns (Canam, 1993; Cohen, 1999). Researchers are beginning to explore a number of protective factors that may influence parental stress in parents of children with cancer. Social support (Abidin, 1992), problem-focused coping (Judge, 1998), and family hardiness (Maddi et al., 2006) have been related to lower levels of stress and more positive outcomes in parents of healthy children, but have not been fully explored in the pediatric cancer population. The current study was designed to assess the relationship between parental …

The Role Of Moral Exemplars In Stanley Hauer's Ethics, Timothy William Walker

Master's Theses

This thesis is on the virtue ethics of Stanley Hauerwas, with particular focus on the role of moral exemplars in his theory. Hauerwas emphasizes the role of what are called "moral exemplars" in his virtue ethics. These are people or characters of narratives that best exemplify virtue. A theory is exemplarist if the moral concepts of the theory are defined in reference to an exemplary person, moral knowledge is gained from knowledge of an exemplar, and moral exemplars are necessary for one's learning to be moral. This definition reflects the three types of roles exemplars could play in a moral …

Reliable Ethernet, Aleksandr Movsesyan

Master's Theses

Networks within data centers, such as connections between servers and disk arrays, need lossless flow control allowing all packets to move quickly through the network to reach their destination. This paper proposes a new algorithm for congestion control to satisfy the needs of such networks and to answer the question: Is it possible to provide circuit-less reliability and flow control in an Ethernet network? TCP uses an end-to-end congestion control algorithm, which is based on end-to-end round trip time (RTT). Therefore its flow control and error detection/correction approach is dependent on end-to-end RTT. Other approaches utilize specialized data link layer …

Equivalent Circuit Implementation Of Demyelinated Human Neuron In Spice, Nathan A. Angel

Master's Theses

This work focuses on modeling a demyelinated Hodgkin and Huxley (HH) neuron with Simulated Program with Integrated Circuit Emphasis (SPICE) platform. Demyelinating disorders affect over 350,000 people in the U.S and understanding the demyelination process at the cellular level is necessary to find safe ways to treat the diseases [9]. Utilizing a previous SPICE model of an electrically small cell neuron developed by Szlavik [32], an extended core conductor myelinated neuron was produced in this work. The myelinated neuron developed has seven active Nodes of Ranvier (nodes) separated by a myelin sheath. The myelin sheath can be successfully modeled with …

Influence Of Vineyard Floor Management Practices On Soil Aggregate Stability, Total Soil Carbon And Grapevine Yield, Kimberly Ellen Adams

Master's Theses

Soil aggregates provide pore spaces of various sizes supplying water, gases and nutrients to plant roots and microorganisms, and facilitate moisture retention and availability. Soil aggregate stability is indicative of soil biological and structural health, and is increased by soil carbon derived from plant roots and the soil microbial biomass. Aggregate stability and soil carbon can be enhanced by increasing organic matter through compost additions or by planting cover crops. Additionally, aggregate stability is enhanced by arbuscular mycorrhizal fungi (AMF) that form a symbiotic association with plant roots, and consolidate soil particles into aggregates through hyphal networks and through the …

The Historical Influence Of Railroads On Urban Development And Future Economic Potential In San Luis Obispo, Adrianna L. Jordan

Master's Theses

Abstract

The Historical Influence of Railroads on Urban Development and Future Economic Potential in San Luis Obispo

Adrianna L. Jordan

Today the sound of a train passing through San Luis Obispo may be intermittent and faint, but persistent nonetheless, a reminder that the railroad (displaced eventually by the automobile and accompanying expansion of highways and road systems, and later by air connectivity) was a significant force in the development of the City of San Luis Obispo. The sound of railroads evokes a sentimental reminder of the past, but the railroad’s continued presence in the city, cutting through its urban fabric, …

Effects Of Chainring Design On Performance In Competitive Cyclists, Christiane Rose O'Hara

Master's Theses

The development of noncircular chainrings to improve cycling performance has been in progress since the 1980’s and continues apace. The aim of this study was to compare performance time and physiological responses in cycling using a standard circular chainring versus a noncircular chainring developed in 2005: the Rotor Q-Ring. Eight competitive male cyclists were pre-tested using the original circular chainrings and also on the initial week of testing. The intervention consisted of cycling with Rotor Q-Rings for four weeks. Post-testing occurred with the original chainrings for the final week of testing. Testing consisted of a maximal or submaximal graded exercise …
