Church Conflict In The Atlanta-Rome District: Developing A Systematic Approach To Conflict And Membership Attrition, James C. Clements

Masters Theses

The decline in church membership and attendance of the 22 churches and 18 ministries of the Atlanta-Rome District (ARD) of the Christian Methodist Episcopal (CME) Church has dramatically impacted the ministries and effectiveness of the Atlanta-Rome District churches in conducting what Jesus Christ commanded in the Great Commission. The congregations whose membership once boasted governmental officials and civil rights icons have all but dwindled to a faithful few that continue to support the Spiritual and fiduciary obligations of the local churches. The rise of non-denominational churches with a more contemporary style of worship as well as internal conflicts within the …

Fat Bias And Culture Shock: Psychosocial Adjustments In Post-Obesity Life, Scott Thomas Macpherson

Masters Theses

Obesity in the United States is unprecedented levels, affecting adults and children as well. As our society has become for sedentary since industrialization, the nation has become fatter. The escalating rate of obesity has had a negative effect on the health of millions of Americans. Health problems such as metabolic disorders and other comorbidities, for instance, hypertension, Type II diabetes, heart disease, weight related cancers etc., (Mozaffarian and Benjamin 2013). The collective cost of obesity is to the nation is staggering, weighing in at $270 billion a year, childhood obesity costs nearly $15 billion alone (Hammond and Levine 2010). This …

Is Tpmt Testing A Predictor Of Duration Of Use Or Long-Term Benefit Of Thiopurine Agents?, Shatoya R. Wilson

Masters Theses

Background: Inflammatory Bowel Disease (IBD) affects as many as 1.3 million Americans and includes both ulcerative colitis (UC) and Crohn’s disease (CD). Recent practices have moved towards using immunomodulators early in the course of disease to prevent disease progression. Patients have shown improved outcomes on immunomodulators compared to aminosalicylates, and reduced risk for tachyphylaxis compared to corticosteroid treatment. Thiopurine agents such as azathioprine and 6-mercaptopurine are immunomodulators often used to treat IBD. Unfortunately, many patients experience cytotoxicity from thiopurine use. Recent studies have shown that patients deficient in thiopurine-S-methyltransferase (TMPT), produce an overabundance of the therapeutic end product, 6-thioguanine nucleotide …

Evaluating The Efficacy Of Convolution Neural Networks In Age At Deat Estimation Using 3d Scans Of The Pubic Symphyseal Face, Melissa A. Brown

Masters Theses

The research presented assesses the utility of machine learning approaches, specifically convolutional neural networks (CNNs), to the estimation of age at death in adult decedents by analysis of the pubic symphyseal face of the os coxa rendered as a 3D image. 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 …

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 …

Application Of A Three-Lever Drug Discrimination Method To Differentiate The Interoceptive Stimulus Effects Of 3, 4-Methylenedioxypyrovalerone And 4-Methylmethcathinone In Male Sprague-Dawley Rats, Trent Bullock

Masters Theses

Psychoactive “bath salts” represent a continuing drug abuse problem. The synthetic cathinones, 3, 4-methylenedioxypyrovalerone (MDPV) and 4-methylmethcathinone (4-MMC) are popular constituents of “bath salts” in the United States and the United Kingdom, respectively. Addiction to these substances has proven difficult to treat, possibly requiring targeted therapeutics. Drug discrimination is a preclinical assay that may aid in treatment development. Thus far, two-lever (drug vs no drug) discrimination studies have exhibited asymmetrical substitution patterns between 4-MMC and MDPV. Therefore, a three-lever discrimination method was employed in which 12 male Sprague-Dawley rats were trained to discriminate 0.5 mg/kg MDPV, 2.0 mg/kg 4-MMC, and …

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 …

Finally, a primary polymer and a secondary Ag encapsulation layer were deposited using screen printing process. The capability of the fabricated thermistor was investigated by measuring its …

An Examination Of Age Labels In Music Related Dissertations And Theses: 2009-2016, Phillicia Jackson

Masters Theses

The life expectancy rate of advanced age individuals has increased dramatically in recent years, creating a greater need for research topics related to this segment of the population. Smith (2009) completed a content analysis of the use of age labels describing this advanced age group using dissertations and theses produced between 1983 and 2008. This current investigation replicated the process used in the earlier study using dissertations and theses completed between 2009 and 2016. The same search procedure, inclusion criteria, and analysis protocol was used, in order to be able to evaluate changes which may have occurred over time. A …

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 …

An Investigation Of Sub-Meter Skill In Stem And Non-Stem Undergraduate Students, Laura A. Tingin

Masters Theses

This study designed a nationally-relevant, valid, and reliable survey that measures STEM and Non-STEM undergraduate student familiarity with sub-meter metric scale and common sub-meter sized science objects. The instrument assesses scalar relationship and scalar magnitude, as explained by Cheek, LaDue, and Shipley (2017). The instrument development was based on an existing Scale of Objects Questionnaire (SOQ) instrument created by Tretter, Jones, Andre, Negishi, & Minogue (2006a) which was modified to be nationally relevant and in an electronic format in two phases: online survey development and undergraduate pilot testing. Online survey development was framed in the tailored design method described by …

Impacts Of Sediment Dredging On Phosphorus Dynamics In A Restored Riparian Wetland, Kimberly Oldenborg

Masters Theses

Global reductions in biodiversity and water quality are having major consequences for ecosystem health and societal well-being. The restoration of riverine floodplains and wetlands provides an ideal opportunity to increase biodiversity and water quality because their hydrologic connectivity to adjacent streams and rivers promotes the formation of heterogeneous habitat while also facilitating their functioning as a nutrient sink, in general. However, many historic floodplains and riverine wetlands have been drained for the creation of agricultural land, resulting in an accumulation of nutrients in the soils. Therefore, restoration practices that hydrologically reconnect former agricultural land to an adjacent stream or river …

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 …

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 …

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 …

Investigating Erosion And Ecological Impacts To An Urban Coldwater Stream Using Multiple Techniques, Daniel T. L. Myers

Masters Theses

Sediment pollution is a major cause of stream degradation. Our objectives were threefold. First, we assessed the impacts of environmental stressors on the structure of fish and macroinvertebrate communities across a gradient of agricultural to urban land cover in a coldwater tributary of the Grand River, Michigan, USA called Indian Mill Creek. We found that instream woody debris, streambed substrate, riffle and pool habitat variability, and riparian conditions affected aquatic macroinvertebrates along an agricultural to urban land cover gradient. We also found that variation in fish community assemblage was driven largely by stream flow and temperature regimes and could be …

Effects Of Eicosapentaenoic Acid (Epa) On Mouse Endothelial Cell Health, Spencer C. Pageau

Masters Theses

Cardiovascular disease is the number one killer of adults in the US (~800,000 lives every year:1 in 3 deaths). Evidence suggests omega-3 fatty acids like eicosapentaenoic acid (EPA), found in fish oils, reduce the risk of developing cardiovascular diseases. Many of these diseases are caused by atherosclerotic plaque development in vessels due to endothelial cell damage initiating inflammatory responses. Recent work argues omega-3 fatty acids stimulate anti-inflammatory responses by binding to Free Fatty Acid (FFA) receptors. Inflammatory responses in endothelial cells alter the expression of many proteins that affect the function of those cells. In particular, gap junction protein (connexin: …

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

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 …

Environmental Factors Influencing Amphibian Community Assemblage In Dune Wetlands On The Lake Michigan Coast, Alex H. Jouney

Masters Theses

Wetlands in dune landscapes provide important breeding habitat for amphibians along the Lake Michigan Coast. Unfortunately, these unique habitats and the corresponding amphibian metapopulations are understudied and threatened. We assessed amphibian species richness and terrestrial habitat type in 16 permanent and ephemeral wetlands along the coast of Lake Michigan in Grand Haven, MI. Wetland area, terrestrial habitat type, depth, hydroperiod, shade, and degree of isolation were measured from April to September of 2017. Nine species of amphibian were found; Green Frog (Rana clamitans melanota) and Spring Peepers (Pseudacris crucifer crucifer) were most abundant and Fowlers Toad …

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

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 …

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 …

A Place For Plastics : Bioplastics, Bacteria And Our Thoughtless Acts, Megan Valanidas

Masters Theses

One third of all plastics end up in the ecosystem. It is time we start designing for this outcome. 311 million tons of plastics were produced in 2014 and that number is projected to more than double by 2050. Just 5% of plastics are recycled. Recycling alone is not mitigating the problem. The carbon footprint alone is massive. China’s recent announcement to no longer recycle the West’s waste promises even more challenges. We need to design for plastics to end up in the ecosystem and in the waste stream. This is where plastics go and this is where they should …

Talking To Computers, Jen Spatz

Masters Theses

A popular belief amongst UX designers is that the more voice user interfaces (i.e. Alexa, Siri, Google Assistant) speak and behave like people, the more functional they will be. But, conversational mimicry is not the only way a screenless computer can communicate information. The scope of sounds humans can interpret, manipulate, and make is broad. This project seeks to identify ways designers can mine this domain for interaction cues that promote a deeper understanding of digital content and the systems that deliver it.

Architecture As An Adapter : A Revolution In High-Rise Corporate Architecture, Nan Zou

Masters Theses

“It is not the strongest of the species that survive, but the one most responsive to change” is the core of Charles Darwin’s Natural Selection theory. This relates not only to biology, but architectural typologies over time.

Office design has gone through many periods of evolution to reflect changes in industry and the workforce: from Ford’s assembly line to office cubicles to the open plan workplace and today’s anti-office. Designers have been mediating between workers and space for better performance for over 100 years -- though none of these anticipated the need for complete flexibility.

Through the development of automated …

Phase one investigates the impact on ecosystems surrounding Miami due to climate shift and rising sea level. During this phase, the effect of sea level rise (SLR) on ecosystems in Miami will be analyzed using the existing Land Cover Distribution Map and Land Cover Change Report posted by the National Oceanic and Atmospheric Administration (NOAA).

Phase two talks about the farming land being taken over by the wetland. However, both wetland and farming …

Harmless Studio, David Thomas Pittman

Masters Theses

This thesis project is oriented around a vegan concept brand called “Harmless Studio.” The project recognizes that industrial design causes and supports the harm of animals through the use of animal materials. This book presents the historical, social, and scientific background of the human-animal relationship as it exists today, and it challenges the common acceptance of that relationship as it is— ultimately suggesting that industrial design need not harm animals to serve human needs. This vegan approach to design is presented through a selection of sustainable, non-animal materials and objects made from those materials. The objects are presented as part …

Squishy Play, Lauren Traugott-Campbell

Masters Theses

Work is part of our identity and dictates how workers spend most of their time in the US. This obsession has truncated our imagination and ability to conceive of alternatives. As a tactic to reclaim free time, I offer a practice I refer to as squishy play in which participants momentarily adopt new social norms to collectively discover new ways of engaging with the world and each other.

I use squishy play as a lens to investigate the power structures, social norms, and material output of late capitalism in the US. Squishy play is generous in its frivolity. It is …

Radically Normal : The Menstruation Issue, Kathryn Smiley

Masters Theses

Hey readers, Periods are normal. But you’d never know that by checking out the average bathroom. The only menstruation-related public restroom fixture considered remotely standard is the trash, the one used to hide the evidence. A tampon dispenser is a rare sighting –a functioning, stocked dispenser, even rarer still.

Dispensers’ exclusion from public space reveals the ways that menstruation is not treated like other natural body functions. Instead, it has long been considered a sign of imbalance and weakness, discussed mainly in hushed tones and sly euphemisms. Historically, the medical profession has greatly contributed to cultural anxieties about women and …
