The study was conducted in three distinct sections: phase one analyzed the model itself and all associated documents, while the researcher also conducted interviews with several individuals with knowledge of the development of the system to …
Designing Framework For The Computer Aided Design Of Silicon Carbide Jfet Circuits In Bleo Environments, Venkata Vinay Naidugari
Designing Framework For The Computer Aided Design Of Silicon Carbide Jfet Circuits In Bleo Environments, Venkata Vinay Naidugari
Electronic Theses and Dissertations
Abstract: circuit design and testing are two essential processes to synthesis of an efficient and reliable circuit. Real-time testing of a circuit through circuit fabrication and development is an expensive and a risky procedure whereas testing the circuit by modelling and simulating is more efficient and inexpensive. Silicon-based semiconductors are the basic components of any modern day electronic devices, and their usage has dominated the marketplace. But these conventional cmos devices cannot exist in an environment consisting of harsh radiation, high temperature and many other environmental conditions, such as venus or mars. However, 6h-sic jfets, which are basic logic gate …
Co2 Adsorption On Volcanic Ash: Net Contribution Of Volcanic Eruptions To The Global Carbon Cycle, Lee New
Co2 Adsorption On Volcanic Ash: Net Contribution Of Volcanic Eruptions To The Global Carbon Cycle, Lee New
Electronic Theses and Dissertations
Adsorption of co2 on mineral surfaces accounts for a small percentage of the terrestrial co2 sink. Volcanic ash is virtually free of co2 when erupted and has a high surface area resulting in a high capacity for co2 adsorption. Volcanism is commonly assumed to be only a source of co2, but pyroclastic eruptions can also potentially serve as a sink. Adsorption was investigated for 6 volcanic ash samples of andesitic composition from four volcanoes: Okmok, Redoubt, Spurr, and Tungurahua. The eruption of volcano redoubt released 0.75 x 109 metric tons of co2 and 55 x 109 kg of ash throughout …
A Kinematic Comparison Of Shoulder And Elbow Dynamics Influenced By The Shoe-Surface Interface In Youth And Adolescent Baseball Pitchers, Jacob Richard Gdovin
A Kinematic Comparison Of Shoulder And Elbow Dynamics Influenced By The Shoe-Surface Interface In Youth And Adolescent Baseball Pitchers, Jacob Richard Gdovin
Electronic Theses and Dissertations
From 1994-2006, 1.5 million baseball injuries were treated within emergency departments across the United States while the upper extremity was the second most commonly injured body part. Although it has been determined that pitch count, pitch type and pitching mechanics are the main contributors to upper extremity pain in baseball pitchers, footwear has not been considered a potential factor. Therefore, the purpose of this study was to determine how baseball-specific footwear [turf shoes (ts) and molded cleats (mc)] affects the shoulder and elbow dynamics of youth and adolescent pitchers during an overhead pitch on various surface inclinations [flat ground (fg) …

Comparing The Depositional Environment Of The Upper Smackover Formation In Southwestern Clarke County, Mississippi And Brooklyn/ Little Cedar Creek Field, Alabama, Elsie Ekene Okoye
Electronic Theses and Dissertations
This research evaluated the depositional settings of the upper Smackover formation in southwestern Clarke County (scc), Mississippi and compared its facies to those of the Brooklyn and little cedar creek fields (bf/lcc) in Conecuh and Escambia Counties, Alabama. The Smackover formation has been a prolific oil producing formation in the Gulf of Mexico since its discovery in Union County, Arkansas in 1937. The discovery of the lcc in 1994 and the bf in 2007 has generated additional interest in the Smackover. The bf/ lcc occur near the updip limit of the upper Jurassic (Oxfordian) Smackover formation. These fields produce from …
Detection Of Sedimentary Depositional Cycles In The Salado Formation, Southeastern New Mexico, Scott Paul Milo
Detection Of Sedimentary Depositional Cycles In The Salado Formation, Southeastern New Mexico, Scott Paul Milo
Electronic Theses and Dissertations
An abundance of evaporitic features is preserved throughout the approximately 2,000-foot-thick Salado formation that is present across west Texas and southeastern New Mexico. The formation and preservation of evaporitic features are largely influenced by hydrology, and so those found in the Salado represent an uninterrupted record of hydrogeologic conditions in what is now the southwestern United States during the late Permian. Because it is home to the Waste Isolation Pilot Plant (WIPP) repository chamber, the salado has been the subject of countless studies ranging from areas of sedimentology, to geochemistry, to geotechnical engineering, to hydrology. However, until now there have …
Sherds With Style: A Ceramic Analysis From A Protohistoric Site In Oktibbeha County, Mississippi., Allison Smith
Sherds With Style: A Ceramic Analysis From A Protohistoric Site In Oktibbeha County, Mississippi., Allison Smith
Electronic Theses and Dissertations
A key part of understanding the lesser known contact period in the Southeastern United States is studying the effects of contact on Mississippian chiefdoms and their descendant population. The Starkville Archaeological Complex is an archaeological pattern of a distinct clustering of contact-era sites in the Blackland Prairie physiographic district of northeast Mississippi. Atkinson (1979) defined these sites as a dispersed settlement pattern with distinct ceramic assemblages associated with European metal. The ceramics are characterized as sandy historic Chickasaw pastes with Mississippian-like distinct curvilinear or angular surface decorations. This thesis is an analysis of the ceramic assemblage excavated in 2016 from …
The Impact Of Simulated Microgravity On The Growth Of The Model Legume Plant Medicago Truncatula, Gemma Elizabeth Lionheart
The Impact Of Simulated Microgravity On The Growth Of The Model Legume Plant Medicago Truncatula, Gemma Elizabeth Lionheart
Electronic Theses and Dissertations
Simulated microgravity has been a useful tool to help understand plant development in altered gravity conditions. Thirty-one genotypes of the legume plant Medicago truncatula were grown in either simulated microgravity on a rotating clinostat, or a static, vertical environment. Twenty morphological features were measured and compared between these two gravity treatments. Within-species genotypic variation was a significant predictor of the phenotypic response to gravity treatment in 100% of the measured morphological and growth features. In addition, there was a genotype–environment interaction (G×E) for 45% of the response variables, including shoot relative growth rate (p < 0.0005), median number of roots (p ∼ 0.02), and root dry mass (p < 0.005). These findings are discussed in the context of improving future studies in plants space biology by controlling for genotypic differences, and by connecting traits to their underlying genetic causes by using genome-wide association (GWA) mapping. In the long-term, manipulation of genotype effects, in combination with M. truncatula’s symbiotic relationships with rhizobacteria and arbuscular mycorrhizal fungi, will be important for optimizing legumes for cultivation on long-term space missions.

The Reptile Gut Microbiome: Its Role In Host Evolution And Community Assembly, Timothy John Colston
Electronic Theses and Dissertations
I characterize the endogenous (gut) microbiome of Squamate reptiles, with a particular focus on the suborder Serpentes, and investigate the influence of the microbiome on host evolution and community assembly using samples I collected across three continents in the New and Old World. I developed novel methods for sampling the microbiomes of reptiles and summarized the current literature on non-mammalian gut microbiomes. In addition to establishing a standardized method of collecting and characterizing reptile microbiomes I made novel contributions to the future direction of the burgeoning field of host-associated microbiome research. Through persistent and rigorous fieldwork I amassed the largest …
Risk, Reward, And The Role Of Habitat Selection On Community Dynamics In Temporary Ponds, Matthew Robert Pintar
Risk, Reward, And The Role Of Habitat Selection On Community Dynamics In Temporary Ponds, Matthew Robert Pintar
Electronic Theses and Dissertations
The processes that generate patterns of species diversity within and among habitat patches are a fundamental topic of interest in ecology. Traditionally, there was a focus on post-colonization effects such as predation, however, pre-colonization processes, such as habitat selection, are equally important determinants of community structure. In freshwater systems, the lethal effects of dominant predators (particularly fish) are well established, while the transition from permanent to temporary ponds is a defining characteristic. This transition produces distinct communities characterized by organisms with complex life cycles and plastic developmental strategies. This means that many organisms occupying habitat patches arrive there by the …
Impact Of Timber Harvest On Mercury Mobilization In A Mixed Pine And Hardwood Forest And Adjacent Lake In Mississippi, Mary Kristen Dickerson
Impact Of Timber Harvest On Mercury Mobilization In A Mixed Pine And Hardwood Forest And Adjacent Lake In Mississippi, Mary Kristen Dickerson
Electronic Theses and Dissertations
With 65% of land area covered in forest, Mississippi is a leader in the timber industry. Whereas forestry provides numerous benefits for humans and wildlife, forest harvest has been hypothesized to increase mercury (Hg) mobilization to aquatic systems. In a forest, Hg mostly accumulates in the upper layer of soil, where associates with organic matter. This top soil is exposed after clear-cutting and thus more susceptible to runoff. Harvest may also change the net balance between Hg methylation and demethylation by microorganisms through changes in redox conditions and addition of carbon sources from decaying logging residues. To better understand the …
Graphene Nano-Composites For Hypervelocity Impact Applications, Alharith Manasrah
Graphene Nano-Composites For Hypervelocity Impact Applications, Alharith Manasrah
Electronic Theses and Dissertations
The Low Earth Orbit (LEO) is a harsh environment cluttered with natural meteoroids and man-made debris, which can travel at velocities approaching 15 km/s. Most space activities within the LEO will encounter this environment. Thus, the spacecraft and its hardware must be designed to survive debris impact. This research introduces new procedures to produce a nano-composite material with mortar-brick nano-structure inspired from nacre. Nacre-like composites were successfully manufactured, based on three host polymers, with a wide range of graphene concentrations. The manufactured exfoliated graphene nano-platelet, embedded in a host polymer, provided good potential for enhancement of the hypervelocity impact (HVI) …
The Impact Of Spiritual Maturity On Clinical Mental Health Counseling Students' Intentions To Engage In Social Justice Advocacy, James Samuel Strickland
The Impact Of Spiritual Maturity On Clinical Mental Health Counseling Students' Intentions To Engage In Social Justice Advocacy, James Samuel Strickland
Electronic Theses and Dissertations
The ACA Code of Ethics (2014) provides a set of professional values which frequently exceeds law in an effort to ensure that clients are protected. As such, The ACA Code of Ethics (2014) states, “counselors are aware of-and avoid imposing- their own values, attitudes, beliefs, and behaviors” (section A.4.b). However, legal cases pertaining to conflict between personal values and professional values when counselors fail to bracket personal values has been on the rise within the counseling profession. Counselors have the professional obligation to protect and advocate for clients’ rights through social justice advocacy which can occur at individual, group, institutional …

To guide the study, the researcher developed four research questions and four null hypotheses. The population of this study was derived from a sample of Mississippi students in Grades K-3 who were administered the Early Literacy STAR assessment for kindergartners and the STAR assessment for first through third-graders. This assessment was administered twice during the 2015-2016 school year. The pretest was given in August; the posttest was given in April/May. These students came from four different schools; two schools had literacy coaches and …
The Impact Of Word-Study Intervention Strategies On Students' Measures Of Reading Comprehension And Fluency, Trenisha Weekley
The Impact Of Word-Study Intervention Strategies On Students' Measures Of Reading Comprehension And Fluency, Trenisha Weekley
Electronic Theses and Dissertations
Despite the existing research regarding effective word-study interventions for struggling adolescent readers, various researchers propose a need for additional research on effective reading interventions to confirm and extend existing knowledge. The current study specifically investigates the impact of the overt/covert and outside-in word-study instructional intervention strategies on struggling adolescent readers’ fluency and comprehension measures. Paired samples t-tests revealed a significant difference in the pretest and posttest fluency scores of participants receiving either overt/covert or outside-in word-study strategy instruction. However, no significant difference occurred between participants’ pretest and posttest comprehension scores. Additionally, ANCOVA statistical analyses revealed no significant differences between the …

The Creation Of Choctaw Central High School And Its Transition To A Bureau Of Indian Affairs Contract School: An Oral History, Fredrick L. Hickmon
Electronic Theses and Dissertations
The members of the Mississippi Band of Choctaw Indians are the invisible heroes of Mississippi. Because of the limited attention placed on the Tribe in Mississippi high school social studies curriculum, and no course of study in any post-secondary institutions in the State, citizens who do not live in close proximity are oblivious to the Choctaws’ existence. Absent is any thought on Mississippi Choctaws deep, rich, background, as the original defenders of the State, or their feelings and contributions toward education. As such this work explored the history of the Mississippi Choctaw with emphasis on education using data collected from …
Understanding Child-Centered Canine Assisted Play Therapy: A Qualitative Collective Case Study, Jennifer Austin-Main
Understanding Child-Centered Canine Assisted Play Therapy: A Qualitative Collective Case Study, Jennifer Austin-Main
Electronic Theses and Dissertations
Children are often referred to counseling for a multitude of reasons (e.g. divorce, trauma, abuse, etc.). Given these challenges faced by so many children, counselors are charged with using evidence based forms of counseling to appropriately help children and their families address these issues. One highly researched and effective therapeutic intervention to working with children is play therapy, more specifically child-centered play therapy (CCPT). A recent trend in play therapy is the incorporation of animals into the play therapy process to facilitate healing and growth (Chandler, 2012; Parish-Plass, 2013; Thompson, 2009), in particular the use of canines in CCPT, known …
Principal Preparedness For Crisis Management In Urban High Schools, Newman C. Robertson
Principal Preparedness For Crisis Management In Urban High Schools, Newman C. Robertson
Electronic Theses and Dissertations
Building level principals are faced with a myriad of responsibilities from teacher observations to meeting with stakeholders to serving as chief academic and administrator in the school. From the student who frequently does not attend class to peer-to-peer fights to the student who brings a weapon to school causing a lockdown, any form of violence (i.e. high, mid-level, low) can be stressful to a principal who has not been properly trained in crisis management and disrupt the learning environment and school safety (Trump 2011; Dupper & Adams, 2002). Thus, the purpose of this qualitative, collective case study is to examine …
The Impact Of Pre-Kindergarten Programs On Student Achievement In Mississippi Elementary Schools, Fletcher B. Harges
The Impact Of Pre-Kindergarten Programs On Student Achievement In Mississippi Elementary Schools, Fletcher B. Harges
Electronic Theses and Dissertations
Each of the states bordering Mississippi invests large amounts of money in providing children with state-funded pre-k programs in their public schools. However, Mississippi falls behind these states and does not similarly invest in this effort to provide many of its children with the opportunity to attend state-funded pre-k programs. Because school readiness is such a huge concern for instructional leaders of Mississippi schools, there is a need to determine the benefits associated with offering pre-k to all students throughout the state. Therefore, the purpose of this study was to examine the impact pre-k has on the academic achievement of …

The research analyzed a single academic year, 2015–16, within the subject district. The study sample consisted of 20 high schools with similar characteristics. Ten of the high schools have a female principal and 10 of the high schools have a male principal. The independent variables of the study were principal gender and teachers’ perceptions of the school climate; dependent variables were the …
The Effects Of Closed-Captioned Television On The Oral Reading Fluency Of Low Socioeconomic 2nd Grade Students, Kristina Livingston
The Effects Of Closed-Captioned Television On The Oral Reading Fluency Of Low Socioeconomic 2nd Grade Students, Kristina Livingston
Electronic Theses and Dissertations
Research into the use of closed-captioning has provided exciting evidence into the possibilities of its usefulness as a literacy tool. Although previous studies have shown the efficacy of closed-captioning as a tool that can assist the deaf and hard-of-hearing, those learning a second language, and hearing students, the existing scholarship lacks important information regarding closed-captioning and its impact on oral reading fluency. Previous scholars have proven that CC can assist all students on word recognition, vocabulary, and reading comprehension; however, there is a dearth of new research focusing on low socioeconomic students from rural communities. This quantitative, quasi-experimental, comparative study …
Interwoven, Preston Tolbert
Interwoven, Preston Tolbert
Electronic Theses and Dissertations
I am regularly amazed by the power of artifacts. Objects can translate intent, skill, function, place, and time, causing us to reflect upon the maker and past users. By incorporating basketry patterns on the surface of my pots, I am creating a connection to my heritage. My family made baskets back many generations. The patterns are incomplete and fade as they weave around the forms. This reflects the nature of objects that have been used to the point of collapse. We live in a society driven by partial consumption and indiscriminant disposal. When something exhibits wear, we get a new …
Southern Discomfort: Performing Femininity In The Deep South, Rachel Whitney Turnipseed
Southern Discomfort: Performing Femininity In The Deep South, Rachel Whitney Turnipseed
Electronic Theses and Dissertations
The “performance” of gender is variable and multifarious, fabricated in reaction to audience, mood, and previous experiences. Starting in childhood, people “police” our gender performances, and profoundly shape our self-presentation and sense of personal identity. We gradually learn to self-edit our performances of gender, after countless critiques by others, which often negatively impact our body image as they preserve “norms,” marginalizing anyone who does not conform. The mixed-media installation, Southern Discomfort: Performing Femininity in the Deep South, examines this process and its impact on young girls. The young, blonde, female figure who appears multiple times in my installation reveal girls …

Impact Of Hydration On Collegiate Athletic Performance, Fatigue, And Recovery, Lauren Woodard
Electronic Theses and Dissertations
The impact of dehydration on several key physiological functions that are critical for athletic performance is well studied. Hydration monitoring has been known to have significant value on impaired physical functions by maximizing performance during training and competition. Impaired physical functions has been suggested as a limitation on explosive strength, musculoskeletal output, cardiovascular output, and proper technique in contact sports. The purpose of this study was to investigate the relationship between hydration levels and physiological profiles that can be used as a proactive approach in monitoring a collegiate athlete’s athletic performance, fatigue, and recovery status. It was hypothesized that insufficient …
Relationships Between Dietary Habits, Demographics, And Hike Outcome Among 2015 Pacific Crest Trail Backpackers, Lauren Ann Black
Relationships Between Dietary Habits, Demographics, And Hike Outcome Among 2015 Pacific Crest Trail Backpackers, Lauren Ann Black
Electronic Theses and Dissertations
This quantitative research study explores the relationship between dietary patterns, hiker demographics, and total miles hiked during a backpacking trip on the Pacific Crest Trail (PCT). Long hiking distances, low rate of thru-hike completion, consumption of processed and ready to eat foods, weight loss, and large time and monetary strains are comthemes accepted anecdotally by the backpacking population11. However, these themes have yet to be adequately researched and validated for long distance backpackers and PCT backpackers specifically. The online survey gathered data from 151 backpackers who hiked the PCT in 2015. Significant positive correlational relationships were found between the number …
Investigating The Glass Ceiling: How Women In Top Media Management Shattered The Glass Ceiling, Jessica Frenshea Love
Investigating The Glass Ceiling: How Women In Top Media Management Shattered The Glass Ceiling, Jessica Frenshea Love
Electronic Theses and Dissertations
This paper explores the successful experiences of women in top media management and their attitudes toward factors of the glass ceiling to identify which factors they perceive as most important, those that remain prominent, and other factors that may have aided in their success. The glass ceiling is the “unseen, yet unbreachable barrier that keeps minorities and women from rising to the upper rungs of the corporate ladder, regardless of their qualifications or achievements” (Cotter, Hermsen, Ovadia, & Vanneman, 2001). This ceiling persists for women in top media management, despite increased feminization in these fields. Previous studies conclude that family …
The Element Spectrum Of A Graph, Milisha Hart-Simmons
The Element Spectrum Of A Graph, Milisha Hart-Simmons
Electronic Theses and Dissertations
Characterizations of graphs and matroids that have cycles or circuits of specified cardinality have been given by authors including Edmonds, Junior, Lemos, Murty, Reid, Young, and Wu. In particular, a matroid with circuits of a single cardinality is called a Matroid Design. We consider a generalization of this problem by assigning a weight function to the edges of a graph. We characterize when it is possible to assign a positive integer value weight function to a simple 3-connected graph G such that the graph G contains an edge that is only in cycles of two different weights. For example, as …
