Assessment Of Reliability And Stability Of Various Visual Search Parameters, Michael Don Mizer
Assessment Of Reliability And Stability Of Various Visual Search Parameters, Michael Don Mizer
MSU Graduate Theses
Research in social science has been on a continuous self-correcting path as scientists find new ways to look at old problems. Recent technology has given us the ability to perform compounded calculations in a fraction of previous times while recording complex measurements with greater degrees of precision. While this is helpful regarding corporeal measures, quantifying cognition is still a difficult task. Recently, many computer-aided eye tracking devices have been developed and used to validate visual search theories. However, few inquiries have been made assessing the reliability and stability of these methods. This study assessed the reliability and stability of visual …
Using Virtual Reality To Improve Sitting Balance, Alice Kay Barnes
Using Virtual Reality To Improve Sitting Balance, Alice Kay Barnes
MSU Graduate Theses
This thesis focuses on using virtual reality (VR) to enhance sitting balance and core strength. It is a study in how to create a VR exercise program which is interesting enough to keep players/patients motivated, but comfortable to play and not overwhelming to the senses. The software used for this study was written with the hope that a later version of it might be used with occupational/physical therapy patients one day. For this master’s thesis, the initial testing has been done with healthy volunteers. The software incorporates what developers know thus far about designing for VR, and it is hoped …
The Spatial Ecology And Microhabitat Selection Of The Pygmy Rattlesnake (Sistrurus Miliarius) In Southwestern Missouri, Dylan Wallace Maag
The Spatial Ecology And Microhabitat Selection Of The Pygmy Rattlesnake (Sistrurus Miliarius) In Southwestern Missouri, Dylan Wallace Maag
MSU Graduate Theses
Despite a wide distribution throughout the southeastern United States, pygmy rattlesnakes (Sistrurus miliarius) have received less research attention than many other rattlesnake species. I captured a total of 33 S. miliarius at the Drury-Mincy Conservation Area (DMCA) and retained 14 large individuals (mostly gravid females) for a radio telemetry study. Snakes were primarily captured during evening road driving surveys and were encountered rarely with any other sampling technique. Sistrurus miliarius are widespread at DMCA where they were encountered in forest, savanna, and glade habitats. Snakes selected microhabitats with more vegetative cover and tree canopy closure than random sites …
The Effect Of Weight Carried And Time Ridden On Back Pain In Horses Ridden During Horse Shows As Determined By Pressure Algometry, Meghan Louise Mothershead
The Effect Of Weight Carried And Time Ridden On Back Pain In Horses Ridden During Horse Shows As Determined By Pressure Algometry, Meghan Louise Mothershead
MSU Graduate Theses
The objective of this study was to determine the effects of weight carried (rider + tack) on back pain in horses used in riding classes and a series of intercollegiate horse shows. Sixteen school horses (431-649 kg) were ridden consistently over a semester. Cross sectional images were used to measure width and put in a mapping program to figure total area. Back pain scores were determined using a pressure algometer on predetermined points over the horses back. Pain scores were recorded over five periods, including 28 d into the semester (P1) and during the show period on three consecutive Fridays …
A Study Of Manganese And Cobalt Incorporated Nickel Oxide Based Core-Shell Magnetic Nanoparticles, Samiul Hasan
A Study Of Manganese And Cobalt Incorporated Nickel Oxide Based Core-Shell Magnetic Nanoparticles, Samiul Hasan
MSU Graduate Theses
The synthesis along with the structural and magnetic properties of manganese (Mn) and cobalt (Co) -incorporated nickel oxide (NiO) inverted core-shell nanoparticles (CSNs) were investigated. The primary objective of this study was to determine the effect of substitution of nickel (Ni) by transition metal ions (Mn2+/Co2+) in affecting the magnetic properties of the resultant CSNs. The core of the CSNs is comprised of NiO and the shell constitutes a Nix(Mn/Co)1-xO phase. The synthesis of the CSNs was accomplished in two steps: first, NiO nanoparticles were synthesized using a thermal decomposition method. In …
Block Copolymer Nanostructures For Inorganic Oxide Nanopatterning, Krishna Pandey
Block Copolymer Nanostructures For Inorganic Oxide Nanopatterning, Krishna Pandey
MSU Graduate Theses
Self-assembled nature of block copolymer (BCP) makes them ideal for emerging technologies in nanometer scale. The micro phase separation between two or more dissimilar polymer blocks of BCP leads to uniform periodic nanostructures of different domains of dimension in the range of 5-100 nm, good for the development of emerging microelectronic and optoelectronics devices. Molecular weight and chain architecture of each blocks govern the morphology evolution; gives different structure like spherical, micelles, lamellae, cylindrical, gyroid etc. The morphology evolution of BCP nanostructure also depends on different external factors as well. In the first work of this thesis, three external factors …
A Comparison Of Traditional, Trial-Based, And Synthesized Contingency Trial-Based Functional Analyses, Kaitlin S. Curtis
A Comparison Of Traditional, Trial-Based, And Synthesized Contingency Trial-Based Functional Analyses, Kaitlin S. Curtis
MSU Graduate Theses
Researchers have developed functional analyses (FAs) to improve efficiency and correspondence that still use core components of the traditional format. The purpose of the current study was to evaluate the correspondence between the trial-based FA and the traditional FA. I also evaluated the correspondence between the synthesized-contingency trial-based FA and the traditional FA. Within this study, I determined that by combining methods, I was able to reduce false negatives for escape found within the trial-based FAs and false-positives found within the synthesized contingency FAs.
Synchronization Of Reproduction In Deertoe Mussel (Truncilla Truncata), Kendell R. Loyd
Synchronization Of Reproduction In Deertoe Mussel (Truncilla Truncata), Kendell R. Loyd
MSU Graduate Theses
Freshwater mussels, Order Unionoida, are diverse and widespread in North America but have suffered general decline and many extinctions in recent decades. The reproductive biology of Unionoida is complex and may be vulnerable to human impacts. Male mussels release aggregates of sperm called spermatozeugmata that drift downstream. Females obtain spermatozeugmata from the water and brood the fertilized eggs internally during development. Many aspects of general reproductive biology are poorly understood, including the mechanisms that coordinate spawning and the route by which sperm meet eggs in the female. The present study focuses on reproduction in the Deertoe (Truncilla truncata), …
Provenance Analysis Of The Grover Gravel Using Detrital Zircon Geochronology, Petrology And Heavy Mineral Analysis, Grant Spoering
Provenance Analysis Of The Grover Gravel Using Detrital Zircon Geochronology, Petrology And Heavy Mineral Analysis, Grant Spoering
MSU Graduate Theses
The Grover Gravel in the St. Louis, Missouri area contains a mix of chert, quartzite, jasper, and ironstone in clast sizes ranging up to 60 cm. The gravel varies in thickness from a veneer to over 30 feet and rests on upland surfaces at elevations sometimes exceeding 300 feet above the floors of major valleys. A pre-Pleistocene age generally has been proposed or assumed for the gravel, which classically has been interpreted to be a meandering-stream deposit atop an extensive flat upland surface, which was subsequently eroded and dissected by rejuvenated streams. However, large quartzite boulders in the gravel also …
Household Chipped Stone Technology At South Cape (23cg8): A Mississippian Hinterland Site In Southeast Missouri, Deseray L. Helton
Household Chipped Stone Technology At South Cape (23cg8): A Mississippian Hinterland Site In Southeast Missouri, Deseray L. Helton
MSU Graduate Theses
Mississippian archaeology is characterized by a longstanding bias towards studying large, mound-bearing sites as opposed to small hinterland sites. Although this bias has diminished in recent decades, research on hinterland sites is still relatively uncommon. This study helps correct that bias through an analysis of flaked stone technological organization at South-Cape (23CG8), a Mississippian hinterland site in Cape Girardeau, Missouri. A sample of flaked stone artifacts from two house features at the site was analyzed. The results indicate that residents at South Cape generally acquired and consumed higher quantities of local lithic raw material than of supra-local lithic raw material. …
The Unraveling Of The Nation-State In The Middle East: Examples Of Iraq And Syria, Zachary Kielp
The Unraveling Of The Nation-State In The Middle East: Examples Of Iraq And Syria, Zachary Kielp
MSU Graduate Theses
After the carnage of World War One and the dissolution of the Ottoman Empire a new form of political organization was brought to the Middle East, the Nation-State. Based on European ideas of Sovereignty and equality between countries; the nation-state was thrust upon these areas that had no history or interest in adopting a foreign form of governance and served the primary purpose of safeguarding the imperial interests of Europe. Compounding their error, the regions of these new nation-states contained populations that had long resented and mistrusted each other. While these countries could be held together by repressive dictatorships for …
On The Existence Of Bogdanov-Takens Bifurcations, Zachary Deskin
On The Existence Of Bogdanov-Takens Bifurcations, Zachary Deskin
MSU Graduate Theses
In bifurcation theory, there is a theorem (called Sotomayor's Theorem) which proves the existence of one of three possible bifurcations of a given system, provided that certain conditions of the system are satisfied. It turns out that there is a "similar" theorem for proving the existence of what is referred to as a Bogdanov-Takens bifurcation. The author is only aware of one reference that has the proof of this theorem. However, most of the details were left out of the proof. The contribution of this thesis is to provide the details of the proof on the existence of Bogdanov-Takens bifurcations.
Peppermint, Anthony Isaac Bradley
Peppermint, Anthony Isaac Bradley
MSU Graduate Theses
This collection contains poetry introduced in a critical way via a theory-based creative nonfiction essay. The work included is a meditation on what identity means on both an intimate and a larger scale, and how the two might be affected by the choices we are faced with from a young age. Elements of pop culture are used alongside rural elements of the surrounding areas to illustrate changing or stagnant viewpoints on topics such as masculinity, gender norms, and queer expression. Peppermint is a document of my mind as it once was, and how it has been shaped up to this …
Survival Analysis: A Modified Kaplan-Meir Estimator, Justin A. Bancroft
Survival Analysis: A Modified Kaplan-Meir Estimator, Justin A. Bancroft
MSU Graduate Theses
The popular Kaplan-Meir estimator has traditionally been used to great effect as a survival function estimator. However, the Kaplan-Meir estimator is dependent upon a maximum likelihood parameter estimator which may not be the best estimator in all cases. We modify the Kaplan-Meir estimator, based on a Bayes parameter estimation, in hopes of providing a more accurate survival estimator for small sample sizes. Core elements of survival analysis are presented, acting as a foundation from which to construct and compare our modified Kaplan-Meir estimator. It is hypothesized that our modified Kaplan-Meir estimator is generally more accurate than the standard Kaplan-Meir estimator …
Czech Cultural Identity: Incompatible With Mass Muslim Immigration And Contributes To Rising European Populism, Alana Thi Vorda
Czech Cultural Identity: Incompatible With Mass Muslim Immigration And Contributes To Rising European Populism, Alana Thi Vorda
MSU Graduate Theses
This thesis examines the respective successes and failures of the Czech experience with integrating Roma and Vietnamese immigrants, and asserts that, given deeply established historical and cultural narratives, and contemporary domestic political considerations as shown in these two previous cases, the Czech Republic is unlikely to effectively assimilate any new surge in Muslim immigration. Developments in the Czech Republic are likely, therefore, to reflect the accelerating populist momentum that is currently sweeping Central and Eastern European states.
Charting Constellations Of Power: Texas Public Education Policy, Hollie Wright
Charting Constellations Of Power: Texas Public Education Policy, Hollie Wright
MSU Graduate Theses
For decades, public education in Texas has been entrenched in neoliberalism-inspired policies that research shows largely fail to produce promised results and have a tendency to perpetuate the very problems advocates claim the policies will solve. This raises questions about the decision-makers and what is happening in the public education policy process. In line with Laura Nader’s directive for more anthropologists to make those in power the subject of their research, I used both ethnographic and social network analysis methods to ‘study up’ in Texas public education. This study describes some relationships of members of the Texas State Board of …
Island Biogeography Of Small Mammals And Associated Ectoparasites In The Ozark Glades, Emily M. Beasley
Island Biogeography Of Small Mammals And Associated Ectoparasites In The Ozark Glades, Emily M. Beasley
MSU Graduate Theses
Island Biogeography Theory (IBT) explains and quantifies broad-scale ecological patterns among islands and isolated habitat patches. IBT predicts that the number of species per habitat patch varies as a function of area and isolation as a result of local colonization and extinction. IBT has been extended to habitat islands and hosts as islands for their associated parasites. In the latter system, host body mass acts as a substitute for island area, whereas host population density is used as a measure of isolation. Using the fragmented Ozark glades and the small mammals therein as a model system, I 1) used a …
Ecology Of Hatchling Alligator Snapping Turtles (Macrochelys Temminckii), Sarah J. Spangler
Ecology Of Hatchling Alligator Snapping Turtles (Macrochelys Temminckii), Sarah J. Spangler
MSU Graduate Theses
Little is known about the first year of life for many of the world’s freshwater turtles. This is due in part to their cryptic nature and the difficulty of locating hatchlings in the wild. The lack of information about this demographically important age group has led researchers to draw conclusions from indirect inferences about survival rates and ecological roles of hatchlings that may or may not be accurate. To begin filling in some of these gaps, I focused on the first year in an alligator snapping turtle’s life. I studied: (1) circadian and circannual patterns of activity, (2) growth rates …
An Assessment Of North Korean Threats And Vulnerabilities In Cyberspace, Jeremiah Van Rossum
An Assessment Of North Korean Threats And Vulnerabilities In Cyberspace, Jeremiah Van Rossum
MSU Graduate Theses
This thesis answers the fundamental questions of what North Korean capabilities and intent in cyberspace are and what North Korean threats and vulnerabilities are associated with these. It argues that although North Korea’s cyberspace resources and capabilities have increased and reached a level that represents an advanced persistent threat, its cyberspace operations have remained restrained and regional. It also argues that North Korea’s valuable assets include its ability to control cyberspace within North Korea and its ability to engage in cyberspace activities and operations from abroad. The thesis recommends that the United States government exploit these assets by denying and …
Comparison Of Trial-Based, Synthesized Trial-Based, And Traditional Functional Analyses, Kara Leigh Forck
Comparison Of Trial-Based, Synthesized Trial-Based, And Traditional Functional Analyses, Kara Leigh Forck
MSU Graduate Theses
I evaluated a synthesized trial-based functional analysis with two students who engaged in problem behavior by combining the methods from the trial-based functional analysis and synthesized contingency functional analysis. Multiple test conditions were combined into one test condition and were evaluated in 2-min trials. The purpose of this study was to compare the degree of correspondence of the results between the trial-based, synthesized trial-based, and traditional function analyses. One participant showed exact correspondence between the three functional analyses, while the other participant showed partial correspondence.
The Effects Of Goal Setting Type And Feedback On Basketball Skill Improvement, Shelby Diane White
The Effects Of Goal Setting Type And Feedback On Basketball Skill Improvement, Shelby Diane White
MSU Graduate Theses
Goal setting is a process that is used by many people in a variety of settings. For example, goals can be set for weight loss, career milestones, or anything a person would like to increase or decrease. According to Locke and Latham (1984), the best way to set a goal is to make sure the goal is specific. If someone wants to lose weight, the individual should state exactly how much weight they would like to lose and set a specific deadline for achieving the weight loss. A second aspect to goal setting is to make sure the goal is …
A Qualitative Study Of Group Therapy Incorporating Rap Music With Inmates, Abigail V. Richards
A Qualitative Study Of Group Therapy Incorporating Rap Music With Inmates, Abigail V. Richards
MSU Graduate Theses
This study aims to explore the lived experiences of inmates who participate in group psychotherapy incorporating elements of rap music. Rap music includes elements such as emotional expression, songwriting, community building, freestyling, and beat, which can be beneficial for individuals experiencing typical symptoms of incarceration such as anxiety, self-discovery, and difficulties regulating emotion. Ten inmates of a Missouri county justice center (50% male) were recruited on a volunteer basis to participate in a five-week psychotherapy group. The study involves psychoeducation, group-drumming, self-expression, and improvisation. Qualitative data were collected through an interview process with participants, including inmates, facilitators and supervisors. Results …
Entangled Trade: Peaceful Spanish-Osage Relations In The Missouri River Valley, 1763-1780, Maryellen Ruth Harman
Entangled Trade: Peaceful Spanish-Osage Relations In The Missouri River Valley, 1763-1780, Maryellen Ruth Harman
MSU Graduate Theses
This thesis examines peaceful Spanish-Osage and Spanish-Missouri relations with an emphasis on the period 1763-1780. Using specific primary source documentation, this study highlights frequent reports from Lieutenant-Governors stationed at St. Louis concerning the thriving fur trade and positive Osage economic exchanges with Spanish-licensed traders. The multi-cultural, multi-ethnic, multi-racial inhabitants and the entangled nature of trade and political interactions in the Missouri River Valley region, specifically in the Upper Louisiana capital, St. Louis, complicated and sometimes undermined peace. During this period, however, the Spanish, Osage, and Missouri nations, sought to overcome these misunderstandings and emphasized instead the mutual benefits of trade …
Yeast Dynamin And Ypt6 Converge On The Garp For Endosome-To-Golgi Trafficking, Pelin Makaraci
Yeast Dynamin And Ypt6 Converge On The Garp For Endosome-To-Golgi Trafficking, Pelin Makaraci
MSU Graduate Theses
Protein recycling is an important cellular process required for cell homeostasis. Results from prior studies demonstrated that Vps1, a dynamin homologue in yeast, is implicated in protein recycling from the endosome to the trans-Golgi Network (TGN). However, the function of Vps1 in relation to Ypt6, a master GTPase in the recycling pathway, remains unknown. The present study reveals that Vps1 physically interacts with Ypt6 if at least one of them is full-length. It was found that overexpression of full-length Vps1, but not GTP hydrolysis-defective Vps1 mutants, is sufficient to rescue abnormal phenotypes in membrane trafficking pathways provoked by loss …
Electronic Structure Evaluation Of Competing Pathways In The Gold(Iii)-Catalyzed Ohloff-Rautenstrauch Cyclosimerization Converting Propargylic Acetates To Carene-Like Natural Products, Jeremy M. Hines
MSU Graduate Theses
Propargylic acetates can lead to complex transformations upon exposure to a gold catalyst. Gold catalyzed transformations also allow for simple synthesis of a number of natural products. Gold (III)-cycloisomerization of a 5-acetoxy-1,6-enyne is reported to proceed through two pathways that differ in the order of major events: cyclization followed by ester migration (“cyclization first”) or the reverse (“migration first”). Both pathways could theoretically proceed in either order. This rearrangement is called the Ohloff-Rautenstrauch rearrangement and has high regio- and stereocontrol affording a bicylo[4.1.0]heptane carbon substructure. This rearrangement allows for the synthesis of the carene class of natural products. Computational modeling …
This Way Girl Comes Bearing Gifts, Alexandra Webster
This Way Girl Comes Bearing Gifts, Alexandra Webster
MSU Graduate Theses
The following collection deals with autobiographical work. My purpose for this thesis was to present poems in which spoke to a girlish attitude under various circumstances such as age, location, and expectation. While this thread of girlhood lends itself as a conceptual framework, the poems themselves vary in style. They move between elements of imagism, narrative, lyricism, meditation, and some code-switching. I found that by letting the poems happen upon recognition and shape themselves out of memorable content rather than by trying to adhere to a strict concentration on one particular style or form allowed me ample materials for building …
Comparison Of Understory Chemical And Mechanical Treatments To Promote Regeneration Of Desirable Forestland Species, Rebecca Rachael Tyler
Comparison Of Understory Chemical And Mechanical Treatments To Promote Regeneration Of Desirable Forestland Species, Rebecca Rachael Tyler
MSU Graduate Theses
Invasive woody plants and trees can have a negative impact on desired tree regeneration in the understory of forest stands, and forage density in grassland sites. An assessment of chemical and mechanical treatments on woody plants in the understory of forestland and in grassland is needed. Two experiments were set up in two forest stands and in two grassland/forest edge sites, with two treatment times during the growing season in the first year of the study. On the forestland sites, chemical and mechanical treatments were applied on undesired woody plants to see if they effect the regeneration of desired tree …
Urban Detention Basin Contamination With Polycyclic Aromatic Hydrocarbons (Pahs) And Metals, Holly Marie Duff
Urban Detention Basin Contamination With Polycyclic Aromatic Hydrocarbons (Pahs) And Metals, Holly Marie Duff
MSU Graduate Theses
Polycyclic aromatic hydrocarbons (PAHs) are organic compounds that can be toxic to wildlife and humans when released to the environment. Coal-tar sealants, which are applied to parking lots or driveways, contribute up to 1,000 times more PAHs than alternative sealants. Over time, these sealants abrade and are transported into drainage networks. Coal-tar sealants are currently used in Springfield, Missouri, however the extent of PAH contamination throughout urban drainage systems is unclear. This study focused on PAH contamination within an urban detention basin on the Missouri State University campus which receives runoff from several coal-tar sealed parking lots. Sediment samples collected …
Contemplative Practices And Post-Secondary Well-Being: Potential Methods For Reducing Test Anxiety, Shannon S. Hayden
Contemplative Practices And Post-Secondary Well-Being: Potential Methods For Reducing Test Anxiety, Shannon S. Hayden
MSU Graduate Theses
Students encounter numerous sources of stress in college from school work to examinations. A proposed method for reducing test related anxiety is contemplative practice (namely, mindfulness meditation and expressive writing). These interventions were used immediately prior to an exam to determine effectiveness on students’ mood and test grade. Although the study produced few statistically significant results, a promising trend in utilizing these interventions for increasing exam grades, increasing positive mood, and decreasing negative mood was uncovered. Each intervention appears to have dissimilar effects on different types of students (i.e., varying degrees of dispositional mindfulness and cognitive test anxiety; for example, …
The Effects Of Motivation And Goal Setting On Response Latency And Mental Effort, Jessica K. Willis
The Effects Of Motivation And Goal Setting On Response Latency And Mental Effort, Jessica K. Willis
MSU Graduate Theses
Researchers have found that performance is enhanced when participants set goals that are specific, difficult, and perceived as attainable. Also, motivation contributes to performance; specifically, intrinsic motivation, approach motivation, and avoidance motivation. Ninety participants were assigned randomly to one of two motivation groups; a goal setting or a control and assessed over a series of memory problems; solvable and unsolvable. Participant’s response latencies (RL) following an unsolvable problem was examined as a function of motivation type. Based upon the results from a 2 (Group; goal setting vs control) X 2 (test order) X 2 (memory problem difference scores) mixed ANOVA, …
