Assessment Of Reliability And Stability Of Various Visual Search Parameters, Michael Don Mizer Dec 2017

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 …


Entangled Trade: Peaceful Spanish-Osage Relations In The Missouri River Valley, 1763-1780, Maryellen Ruth Harman Dec 2017

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 …


Block Copolymer Nanostructures For Inorganic Oxide Nanopatterning, Krishna Pandey Dec 2017

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 …


Using Virtual Reality To Improve Sitting Balance, Alice Kay Barnes Dec 2017

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 …


Charting Constellations Of Power: Texas Public Education Policy, Hollie Wright Dec 2017

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 …


An Assessment Of North Korean Threats And Vulnerabilities In Cyberspace, Jeremiah Van Rossum Dec 2017

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 …


Island Biogeography Of Small Mammals And Associated Ectoparasites In The Ozark Glades, Emily M. Beasley Dec 2017

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 …


On The Existence Of Bogdanov-Takens Bifurcations, Zachary Deskin Dec 2017

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.


Czech Cultural Identity: Incompatible With Mass Muslim Immigration And Contributes To Rising European Populism, Alana Thi Vorda Dec 2017

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.


Survival Analysis: A Modified Kaplan-Meir Estimator, Justin A. Bancroft Dec 2017

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 …


The Unraveling Of The Nation-State In The Middle East: Examples Of Iraq And Syria, Zachary Kielp Dec 2017

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 …


A Qualitative Study Of Group Therapy Incorporating Rap Music With Inmates, Abigail V. Richards Dec 2017

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 …


Comparison Of Trial-Based, Synthesized Trial-Based, And Traditional Functional Analyses, Kara Leigh Forck Dec 2017

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.


A Comparison Of Traditional, Trial-Based, And Synthesized Contingency Trial-Based Functional Analyses, Kaitlin S. Curtis Dec 2017

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.


Household Chipped Stone Technology At South Cape (23cg8): A Mississippian Hinterland Site In Southeast Missouri, Deseray L. Helton Dec 2017

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 Spatial Ecology And Microhabitat Selection Of The Pygmy Rattlesnake (Sistrurus Miliarius) In Southwestern Missouri, Dylan Wallace Maag Dec 2017

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 Dec 2017

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 …


Provenance Analysis Of The Grover Gravel Using Detrital Zircon Geochronology, Petrology And Heavy Mineral Analysis, Grant Spoering Dec 2017

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 …


Yeast Dynamin And Ypt6 Converge On The Garp For Endosome-To-Golgi Trafficking, Pelin Makaraci Dec 2017

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 …


Peppermint, Anthony Isaac Bradley Dec 2017

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 …


Ecology Of Hatchling Alligator Snapping Turtles (Macrochelys Temminckii), Sarah J. Spangler Dec 2017

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 …


A Study Of Manganese And Cobalt Incorporated Nickel Oxide Based Core-Shell Magnetic Nanoparticles, Samiul Hasan Dec 2017

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 …


Synchronization Of Reproduction In Deertoe Mussel (Truncilla Truncata), Kendell R. Loyd Dec 2017

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), …


The Effects Of Goal Setting Type And Feedback On Basketball Skill Improvement, Shelby Diane White Dec 2017

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 …


Cognitive Origin Of Reported Goals, Nikolas M. Pate Aug 2017

Cognitive Origin Of Reported Goals, Nikolas M. Pate

MSU Graduate Theses

Goal setting theory assumes that goals that drive self-regulation exist in ‘goal structures’ and that asking participants to report their goals draws from these pre-existing structures. This study tested this assumption of pre-existing goals against the notion that goals are generated by goal-setters at the time they are requested to report their goals. A model of working memory was used to differentiate between goals existing in memory or goals generated on the spot. Participants were 211 students from a large Midwestern public university, randomly assigned to one of two groups. The experimental group participants reported their career goals while also …


Habitat Associations With Small Mammal Communities At Wilson's Creek National Battlefield, Stephanie Anne Ellison Aug 2017

Habitat Associations With Small Mammal Communities At Wilson's Creek National Battlefield, Stephanie Anne Ellison

MSU Graduate Theses

The purpose of this study was to aid the National Park Service at Wilson’s Creek National Battlefield with the reported habitat monitoring and management goals through vegetation and wildlife surveys within the park. I provided a description of two major habitat types that are of ecological concern, which included non-native ruderal grasslands and upland deciduous woodlands and forests. I evaluated small mammal communities to determine factors that may affect the detection of individual species and examined habitat associations with occupancy, as small mammals are good indicators of habitat quality. My study highlights the need to manage invasive species such as …

Simplifying Methods For In Vitro Metamorphosis Of Glochidia, Morgan A. Kern Aug 2017

Simplifying Methods For In Vitro Metamorphosis Of Glochidia, Morgan A. Kern

MSU Graduate Theses

Captive culture of Unionoid mussels is complicated by the parasitic larval stage, which normally requires a host fish for metamorphosis. Alternatively, some mussel species can metamorphose in vitro, i.e. in an artificial medium in Petri dishes. Most workers have used 5% CO2 atmosphere and bicarbonate to stabilize pH, requiring a specialized incubator. In the present study, in vitro metamorphosis success of Anodonta oregonensis and other species were higher or similar in air than in 1%, or 5% CO2. The nutritional role of the medium was tested by substituting physiological saline without nutrients at varying intervals before …

MSU Graduate Theses

The changing composition of early childhood classrooms challenges teachers to be more responsive to the diverse needs of all children. This study explores the challenges and successes early childhood teachers experience with facing diversity in their classrooms. The purpose of this qualitative interview study was to investigate kindergarten teachers’ perceptions, beliefs, and teaching practices concerning anti-bias education in Seoul, South Korea. There were two groups of in-service kindergarten teachers, four teachers in each group, who participated in one-on-one interviews with structured and open-ended questions. The teachers in one group had more experience with teaching in diverse classroom settings than the …


Going Home, Emily Susannah Budd Aug 2017

Going Home, Emily Susannah Budd

MSU Graduate Theses

I continue to explore the space that exists between worlds and ideology in an attempt to blur the demarcation between them. Using the everyday, I attempt to show features of the uncanny and sublime nature of common objects by including fantastic elements while maintaining an illusion of reality. Rather than showing the audience one true meaning, I offer them a lens to one of the infinite possibilities. The story is left for the observer to complete, each narrative unique and valid. As the Western viewer tends to seek out absolutes and categorical placements, I try to create a venue that …
