Tearing The Guts Out Of The Wehrmacht: A Re-Examination Of The Russo-German War, Randall Wells, Jr.
Tearing The Guts Out Of The Wehrmacht: A Re-Examination Of The Russo-German War, Randall Wells, Jr.
Masters Theses
Nazi Germany invaded the Soviet Union on 22 June 1941. Hitler’s plan to annihilate Germany’s Eastern neighbor and populate the vast Russian expanse with his own people was as ambitious as it was adventuristic. Although it began successful, the Russo-German War quickly devolved into a quagmire as Russian troops outfought their German opponent and beat them back to Berlin. Contrary to prevailing historiography, the Wehrmacht’s loss on the Eastern Front cannot be solely attributed to a failure to equip German troops with proper winter clothing, an inadequate logistics network or Hitler’s interference in military decisions. For an army that had …
Sinister Subshade: The Revival Of The Ku Klux Klan In Modern America, Taylor Ashton Spicer
Sinister Subshade: The Revival Of The Ku Klux Klan In Modern America, Taylor Ashton Spicer
Masters Theses
Through the implementation of qualitative analysis this study purposes to discover if there exists possible correlation between President Trump’s assent to power and the increasing legitimacy of the Ku Klux Klan. Using Ernest Bormann’s (1972) Fantasy Theme Criticism, the Knights Party official website and the Donald J. Trump official website are systematically analyzed for dramatis personae (character), setting and action. The rhetorical visions compiled from each analysis are compared employing Ernest Bormann’s (1980) Symbolic Convergence Theory. Resulting analysis suggests little to no correlation between the two movements. The two websites provide very different rhetorical visions with no overlap. The work …
The New England Narrative, Cynnamon C. Mathis
The New England Narrative, Cynnamon C. Mathis
Masters Theses
Though equally successful, noteworthy, inspiring, and crucial as the contributions to American Independence made by New England women patriots, the contributions made by North Carolinian women patriots are excluded from the history of America’s founding as a direct result of sectional nationalism.

14-3-3 Protein Rad24 And Its Effect On Mid1 Localization And Contractile Acto- Myosin Ring Assembly During Cytokinesis In S. Pombe, Anissa P. Grawe
14-3-3 Protein Rad24 And Its Effect On Mid1 Localization And Contractile Acto- Myosin Ring Assembly During Cytokinesis In S. Pombe, Anissa P. Grawe
Masters Theses
In animal and yeast cells, cell division (cytokinesis) is facilitated by the formation of a contractile acto-myosin ring (CAR). Proper CAR formation and constriction is heavily reliant on the temporal regulation, phosphorylation, and localization of key proteins. In the fission yeast S. pombe, Mid1 is an important dimeric CAR scaffolding protein that connects the contractile apparatus to the plasma membrane at the right place and time during cytokinesis. Mid1 is confined to both the nucleus and protein assemblies called nodes during interphase, and transitions to the cell cortex at mitotic entry as nodes mature and coalesce into the CAR. Rad24 …
Deep Reinforcement Learning For Autonomous Search And Rescue, Juan Gonzalo Cárcamo Zuluaga
Deep Reinforcement Learning For Autonomous Search And Rescue, Juan Gonzalo Cárcamo Zuluaga
Masters Theses
Unmanned Aerial Vehicles (UAVs) are becoming more prevalent every day. In addition, advances in battery life and electronic sensors have enabled the development of diverse UAV applications outside their original military domain. For example, Search and Rescue (SAR) operations can benefit greatly from modern UAVs since even the simplest commercial models are equipped with high-resolution cameras and the ability to stream video to a computer or portable device. As a result, autonomous unmanned systems (ground, aquatic, and aerial) have recently been employed for such typical SAR tasks as terrain mapping, task observation, and early supply delivery. However, these systems were …
College Self-Funding Predicting Deviant Behaviors, Blake A. Darling
College Self-Funding Predicting Deviant Behaviors, Blake A. Darling
Masters Theses
This study examines the effects of the source of college funding on student participation in four deviant behaviors: monthly binge drinking, monthly marijuana use, illicit drug use, and academic cheating. Using secondary data from a self-reported online survey conducted at a midwestern University, competing hypotheses based in general strain theory and social bond theory, were tested. Logistic regression analyses of the four deviant behaviors suggest that the source of college funding has a very limited effect. Only in the cases of marijuana use and illicit drug use were significant relationships observed; where students whose funding came from their parents were …
Use Of Fluorescein Dye For Characterizing Water And Solute Flux Across The Groundwater – Surface Water Interface, Ryan Nicholas Cascarano
Use Of Fluorescein Dye For Characterizing Water And Solute Flux Across The Groundwater – Surface Water Interface, Ryan Nicholas Cascarano
Masters Theses
Quantifying groundwater discharge across the sediment—surface water interface remains a challenge due to streambed heterogeneity and the integration of disparate measurements over a continuum of spatial and temporal scales. In this study, mini-piezometers are first used to identify areas of groundwater discharge in lakes and streams, and micro-pulses of fluorescein dye are released at precisely known shallow depths as a conservative tracer. The use of fluorescein dye allows for visual dye detection regardless of light conditions, and measurements of dye concentrations over time using a fluorometer are used to generate high resolution breakthrough curves. Accurate determination of groundwater velocity and …

Contribution Of Monoaminergic Mechanisms To The Discriminative Stimulus Effects Of 3,4-Methylenedioxypyrovalerone (Mdpv) In Sprague-Dawley Rats, Harmony I. Risca
Masters Theses
3,4-Methylenedioxypyrovalerone (MDPV) is a popular synthetic cathinone reported to have a high abuse potential and comparable pharmacological actions to those of cocaine. The aim of this study was to evaluate a variety of monoaminergic agents for substitution, potentiation, or antagonism in rats trained to discriminate MDPV. Male Sprague-Dawley rats were trained to discriminate 0.5 mg/kg MDPV and a variety of monoaminergic drugs were tested for substitution and/or potentiation of the MDPV cue. In separate experiments, stimulus antagonism tests were conducted with selected dopamine antagonists or serotonin antagonists in rats trained to discriminate 1 mg/kg MDPV. Full substitution for MDPV was …
Time Evolution Of Ecog Network Connectivity In Patients With Refractory Epilepsy, Michael J. Selesko
Time Evolution Of Ecog Network Connectivity In Patients With Refractory Epilepsy, Michael J. Selesko
Masters Theses
Epilepsy is a common neurological disorder that causes recurrent, unprovoked seizures. Focal, refractory epilepsy is characterized by seizures that start in a specific area in the brain and do not respond to antiepileptic medication. This study was conducted to characterize the connectivity of the focal brain region where seizures originate, known as the epileptogenic zone. Connectivity was measured from electrocorticogram (ECoG) recordings, during seizure events, using information theoretic measures mutual information (MI) and (TE). MI is the amount of information shared between two discrete random variables. TE is the directed information transfer between two discrete random variables. MI provides information …

Effects Of Fire Season And Temperature On A Spotted Knapweed (Centaurea Stoebe) Infested Grassland, Zachery T. Pitman
Masters Theses
Invasive species, including the non-native forb Centaurea stoebe (spotted knapweed), constitute an imminent threat to degraded and restored native prairies. Considering the major threat that C. stoebe poses to imperiled prairie ecosystems, I examined the effectiveness of fire as a control agent of C. stoebe and (±)-catechin. I conducted a 2-year experiment in part of a restored tallgrass prairie community at Pierce Cedar Creek Institute in Barry County, Michigan between May and August of 2016 and 2017. My experiment consisted of individually burning 60 1-m² plots with a propane torch to achieve high (316° C) and low (103° C) temperatures …
Occupancy And Detection Of Yellow Perch In Great Lakes Coastal Wetlands, Kaitlyn M. Dykstra
Occupancy And Detection Of Yellow Perch In Great Lakes Coastal Wetlands, Kaitlyn M. Dykstra
Masters Theses
Accurately estimating the distribution of a species is important for managing sustainable populations of fishes. The Yellow Perch Perca flavescens is an important sport fish in the Great Lakes region and one of the most abundant fishes in Great Lakes coastal wetlands, which they commonly use for spawning and nursery habitat. Many fisheries management decisions are based on results from sampling fish assemblages, but these methods rarely account for incomplete detection (i.e., presence of a species that is not detected by sampling), which could create biased results. We applied the method of occupancy modeling, which accounts for incomplete detection, to …
The Effect Of Alpha-Linolenic Acid (Ala) On Endothelial Cell Expression Of Connexin43, Benjamin Pichette
The Effect Of Alpha-Linolenic Acid (Ala) On Endothelial Cell Expression Of Connexin43, Benjamin Pichette
Masters Theses
Atherosclerosis is the leading cause of cardiovascular diseases like myocardial infarctions and strokes. The formation of these atherosclerotic plaques occurs through localized inflammatory responses in blood vessels. Epidemiological evidence suggests omega-3 fatty acids (FAs) decrease vascular inflammation. The omega-3 FAs eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) reduce inflammation through pathways that may include the free fatty acid-4 (FFA-4) receptor. While EPA and DHA are well studied, less is known about the essential omega-3 FA from which they are synthesized: alpha-linolenic acid (ALA). Thus, this study will investigate whether ALA can activate the FFA-4 receptor and thereby contribute to anti-inflammatory …
Assessment Of Invasive Gypsophila Paniculata Control Methods In The Northwest Michigan Dunes, Emma K. Rice
Assessment Of Invasive Gypsophila Paniculata Control Methods In The Northwest Michigan Dunes, Emma K. Rice
Masters Theses
Gypsophila paniculata is an invasive species in Michigan’s northern lower peninsula and a problem invasive in much of the northern United States and Canada. Gypsophila paniculata readily outcompetes native plants in sandy, well-drained soils due to its deep taproot, which allows access to scarce resources. It reproduces and disperses mainly by seed, but the phenology of seed maturation is poorly understood. Gypsophila paniculata is of particular concern in lakeshore dunes because the areas where it is most dense are also populated by several endemic and threatened species. Despite many years of intensive management, high densities of G. paniculata persist …
Estimating Components Of Stream Metabolism Using The Free Water Dissolved Oxygen Method, Jay R. Zuidema Jr.
Estimating Components Of Stream Metabolism Using The Free Water Dissolved Oxygen Method, Jay R. Zuidema Jr.
Masters Theses
Stream ecosystem metabolism is commonly measured in stream ecology studies in order to understand the functioning of the stream ecosystem and as an indicator of stream health. One common method for gathering the time series data required to estimate stream metabolism is the free water dissolved oxygen method, which involves measuring dissolved oxygen in freely moving water. This is accomplished by taking measurements at a single location (one-station monitoring method) or at two locations (two-station monitoring method). In conjunction with these data, a process-based model of dissolved oxygen dynamics is used to estimate gross primary production, respiration, and net production. …
Genetic Structure Of Invasive Baby’S Breath (Gypsophila Paniculata) Populations In A Michigan Dune System, Hailee B. Leimbach-Maus
Genetic Structure Of Invasive Baby’S Breath (Gypsophila Paniculata) Populations In A Michigan Dune System, Hailee B. Leimbach-Maus
Masters Theses
Invasive species can reduce biodiversity of a system by outcompeting native species for resources, changing the physical characteristics of a habitat, and altering natural disturbance regimes. Coastal sand dune ecosystems are dynamic with elevated levels of disturbance, and as such they are highly susceptible to plant invasions. The topography, geographic distribution of preferred habitat, and disturbance regime in an ecosystem can influence where an invasive plant becomes established, its dispersal patterns, and how densely it grows. One such invasion that is of major concern to the Great Lakes dune systems is baby’s breath (Gypsophila paniculata). The invasion of …

Age at death estimation is an important duty of forensic anthropologists working in medico-legal contexts, as well as bioarcheological researchers. The purpose of this study is to evaluate the accuracy of a CNN relative to the performance of human observers using traditional methods of age estimation. To accomplish this, a CNN created for this project and expert anthropologists were …
Computational Study Of The Nature Of Tetrel Bond, Yama Aman
Computational Study Of The Nature Of Tetrel Bond, Yama Aman
Masters Theses
For more than a hundred years, the type of a chemical bond has been distinguished according to the relative electronegativities of chemical units at the ends of a bond. Whereas, the bond of unequally electronegative on both ends is called a polar covalent or even ionic bond or a non-polar covalent bond in case of both equal. Regardless the type of bonded elements, the whole idea for the bond was believed to be electron driven only. In the 20th century the development of the idea, that not just the electronic relation but specific elements are also able to characterize the …
On Wlan Fingerprint Indoor Positioning Systems Clustering, And Classification For Enhanced Performance, Haider G. Al Glehawi
On Wlan Fingerprint Indoor Positioning Systems Clustering, And Classification For Enhanced Performance, Haider G. Al Glehawi
Masters Theses
The most economic and affordable IPS are those incorporating existing infrastructure, such as the widely spread Wireless Local Area Network (WLAN). The Received Signal Strength (RSS) fingerprinting-based system is one of the most promising and powerful techniques so far to be used for indoor positioning. However, there are two challenges in using RSS based IPS; the first challenge is the variation of RSS to indoor multipath propagation, and the second is the high number of Access Points (APs) that are deployed in the region of interest. The first issue leads to degradation in the performance of RSS based IPS, while …
Evaluation Of Generalized And Specific Token Reinforcement Using A Paired Stimulus Preference Assessment And Progressive Ratio Schedules, Haily K. Traxler
Evaluation Of Generalized And Specific Token Reinforcement Using A Paired Stimulus Preference Assessment And Progressive Ratio Schedules, Haily K. Traxler
Masters Theses
Skinner (1953) stated that the effects of generalized conditioned reinforcers should maintain longer than specific conditioned reinforcers because their effects are not dependent on a particular motivating operation. Tokens easily model different levels of generality because tokens can be paired with one or more back-up reinforcers. In the current study, three types of tokens were assessed that could be exchanged for either salty snacks, food and drinks offered in a small marketplace, or money on a gift card. Token preferences were assessed using a Paired Stimulus preference assessment and a progressive ratio (PR) task. The results of the preference assessment …
A Parametric Analysis Of Choice Under Risk, David W. Sottile
A Parametric Analysis Of Choice Under Risk, David W. Sottile
Masters Theses
Accurate assessment of risk propensity is important because risky choices underlie a broad range of behavioral problems. The Balloon Analogue Risk Task (BART) is an assessment that measures propensity to engage in risky choice. While this is a useful assessment, the BART changes two variables that affect risky choice simultaneously, probability of an undesirable outcome and stake size, which cannot be separated within the context of the BART. The goal of this study was to evaluate the separate and combined effects of key factors that are likely to risky choice (Magnitude of payoff, probability of an undesirable outcome, and stake …
Is Religion An Effective Rehabilitation Method? Comparing The Results, Ashley Kittrell
Is Religion An Effective Rehabilitation Method? Comparing The Results, Ashley Kittrell
Masters Theses
Faith-based rehabilitation programs receive both praise and criticism from the criminal justice academic community. Critics argue they risk violating inmates’ constitutional rights by forcing them to participate and adhere to religious principles and activities. Supporters of faith-based programs claim that they reduce both recidivism rates and high incarceration costs. Current studies evaluating the effectiveness of faith-based programs have struggled to accurately define and measure either variable. This study compares two popular faith-based programs to a similar secular program to determine if there is a significant difference in recidivism rates using an independent t-test.
Defining Contagion : Examining Imagination As A Source Of The Infection In Print Studios, Joshua Tangen
Defining Contagion : Examining Imagination As A Source Of The Infection In Print Studios, Joshua Tangen
Masters Theses
In this thesis, I attempted to define a contagious component of art education within a community print shop. In this quest, I examine theories around imagination, creativity, and psychology through an analysis of the work of Maxine Greene, Kieran Egan, Ken Robinson, and Mihaly Csikszentmihalyi. Gathered from a variety of sources that include, books, scholarly articles, and online video, I link Greene’s concepts of what role imagination plays in critical thinking and empathy, Egan’s promotion of imagination’s ability to create personal and emotional engagement, Robinson’s ideas about creativity in learning, and Csikszentmihayli’s theory of flow. Connecting these four philosophers are …
Space In Between : Finding A Third Space For Art Education & Creative Community, Denise Gunter
Space In Between : Finding A Third Space For Art Education & Creative Community, Denise Gunter
Masters Theses
The arts remain in the shadow of Education’s assumptions: the arts are a subject of skill, a place for the finished product. While counter efforts, both current and past, have been pursued by the field of Art Education to promote art as an everyday tool, the static presence of this regulated pedagogical space makes it difficult to shift art accessibility from the artist to society as a whole. In response, it is certain the field demands a new environment. A space that validates its convictions and passions into something translatable to the masses, so art education may stand alone. In …
