P-Lax : Toys For Adults, To Play & Relax, Zhizi Liu

Masters Theses

Adults don’t play enough. There is so much emphasis on working and being productive in modern day life, but this can have negative effects—for an adult this can lead to high stress and a sense of guilt when one isn’t being productive. My mission is to help adults de-stress and take a break from work by reintroducing play into their day-to-day interactions. Toys for children are often used for educational purposes and to help enhance their creativity and social abilities; toys for adults can instead used to improve mood, and to help release pressure that is built up from everyday …

Midwives For Haiti: Process Evaluation, Denielle M. Riley

Masters Theses

The reduction of maternal mortality is a long-time international objective. One often underemphasized component of addressing complex and context-driven health problems, such as maternal mortality, is the importance of program evaluation. Program evaluation has been identified as particularly scarce among safe motherhood initiatives, which seek to reduce maternal deaths and improve the health outcomes of mothers (Freedman et al., 2007). Useful program evaluation starts with process evaluation. This study is a case study process evaluation of postpartum data collection, which utilizes interviews, observations, and document review. The purpose of this study was to evaluate, describe, and compare the intended and …

Effective Population Size, Demography, And Viability Of Eastern Massasaugas (Sistrurus Catenatus) In Southwest Michigan, Danielle R. Bradke

Masters Theses

As humans increasingly exploit natural areas, wildlife populations face a growing number of threats that often result in population decline and isolation. Small, isolated populations are vulnerable to extirpation due to both genetic and demographic factors. Yet, low detectability of many imperiled species often precludes the collection of population-level data important for assessing population viability and implementing successful conservation. The eastern massasauga (Sistrurus catenatus) is a cryptic pitviper that has been extirpated throughout much of its historic range due to agricultural conversion of wetland habitat and other synergistic threats. Consequently, this species is federally listed as threatened in both the …

“The Cracked Pots Of Humanity”: Post-World War Ii American Literary Perspectives On Psychiatric Treatment/Containment Of Mental Disorders, Jennifer Chichester

Masters Theses

This thesis examines the ways in which characters in Shirley Jackson’s The Haunting of Hill House and The Bird’s Nest, Ken Kesey’s One Flew Over the Cuckoo’s Nest, and John Kennedy Toole’s A Confederacy of Dunces grapple with the concept of “madness” on individual and societal levels. Each of these Post-World War II novels question whether “madness” is a social construct. Is the person mad, or is society? These three novels, written in an era when inpatient psychiatric care was losing its prominence as a method for treating those deemed insane, reflect the growing trend of deinstitutionalization in the 1950s …

Reasons For Their Departure: A Look At Undergraduate Women Who Abandon Stem Majors, Nicole S. Rombach

Masters Theses

Despite surpassing undergraduate men in degree completion, undergraduate women are still underrepresented in certain STEM majors and depart from these fields at higher rates. Much of the existing research on this topic, however, is quantitative in nature and conducted at large research institutions. This study sought to gain a better understanding of the reasons why undergraduate women switched from STEM to non-STEM majors at a large, Midwest liberal arts institution. A qualitative, phenomenological design was used to identify the reasons students identify as important in their decision to switch majors, the ways in which gender might have been tied to …

Batman As Monomyth: Joseph Campbell, Robert Jewett, John Shelton Lawrence, Frank Miller, Grant Morrison, Scott Snyder, And The Hero’S Journey To Gotham, Andrew Thigpen

Masters Theses

In 1988, Jeffrey Lang and Patrick Trimble wrote an article called, “Whatever Happened to the Man of Tomorrow,” which explains the absence of a hero of the American monomyth in comic books. The American monomyth was proposed by Robert Jewett and John Shelton Lawrence and describes a community in harmonious paradise threatened by evil. The normal institutions of law and order fail to defeat the evil, but fortunately, a hero from outside the community arises to resist temptation, defeat the evil, and return the community to its peaceful condition. Lang and Trimble observe the death of Superman during the events …

Spatial Ecology Of The Adult And Neonate Eastern Box Turtle In A Forested Landscape, Patrick B. Laarman

Masters Theses

A thorough understanding of spatial ecology is fundamental when developing and implementing conservation strategies for imperiled turtle species. I investigated spatial ecology of adult and neonate eastern box turtles in the Manistee National Forest (MNF), Michigan. My primary objectives were to evaluate relative habitat preferences of adults and document residency time of neonates in natal openings. I radio-fitted 25 adults, protected 64 nests, and radio-fitted 66 neonates. Mean home range size for adults (n = 25 turtles) was 16.4 ha ± 2.4 SE (100% Minimum Convex Polygon). I detected non-random habitat use by adults (Wilks Ʌ = 0.202, df = …

The Role Of Metastasis Suppressor Cd82 In The Deactivation Of The C-Met Signaling Pathway In Prostate Cancer, Katie L. Uhl

Masters Theses

BACKGROUND AND PURPOSE: Prostate cancer is the second leading cause of cancer deaths among men in the United States. Metastasis plays a major role in patient prognosis and treatment options. One of the factors that influences metastasis is the activation of the c-Met signaling pathway. Activation of the growth factor c-Met results in cytoskeletal rearrangement, migration, and invasion. Previous studies have shown CD82 to act as an active metastatic suppressor in normal, healthy cells and is downregulated in various forms of cancer. When CD82 is re-expressed in cancer cells, the cells no longer express metastatic characteristics. The purpose of this …

Effect Of Michigan State-Funded Child And Adolescent Health Center (Cahc) In Directing The Health And Wellness Of West Michigan's Oakridge School District, Amber M. Bytwerk

Masters Theses

School-based health centers are an integrated and proactive resource to promote health and wellness of students, as well as the surrounding community. Literature shows that the number of school-based health centers are steadily increasing across America, with few looking at their integration into the population. Within West Michigan, only two such clinics are operational. Applying data from the Michigan Profile for Healthy Youth (MiPHY) and primary data collected from school staff and administrators, an evaluation was conducted on the interconnectedness and behavioral effects of a community branching from the school-based health center. This project is based on review of: the …

Religion, Science, And Truth In The Human Experience: Poetry As Living Synthesis In Walt Whitman’S Leaves Of Grass, Karen E. Luidens

Masters Theses

Walt Whitman’s great masterpiece Leaves of Grass stands out in the canon of nineteenth-century American poetry for both its innovations in form and its bold ventures into controversial subjects. One such subject is the role of science as opposed to religion in shaping the modern worldview. Whitman’s poetry alternately and at times simultaneously expresses both materialistic and metaphysical cosmologies, criticizing and casting away ancient traditions as often as he calls on them for inspiration.

In this paper I explore the influence of contemporary science on Whitman’s worldview, analyze how its theories shape the cosmology presented by his poetry, and discuss …

Finally, The Molecular Characterization Of Geitleria: Results In The Formation Of A Newly Described Nostocales (Cyanobacteria) Clade Geitleriaceae Fam. Prov., Sp. Prov, Jonathan Kilgore

Masters Theses

Geitleria was described from a limestone cave in Israel, and subsequently reported from caves of France, Romania, Spain, and Florida, Costa Rica, and Cook Islands. It is morphologically unusual in that it has true-branching, but no heterocytes. A morphologically distinct species of Geitleria was recently collected from a limestone cave in Great Smoky Mountains National Park, Tennessee, and is herein described as G. appalachiana sp. prov. Sequence data for 16S-rRNA and rpoC1 loci for the species were obtained from field material using single filament PCR. Phylogenetic evidence indicates that Geitleria does not belong to any family in the Nostocales containing …

The Effects Of Feedback Modality On Performance, Garrett D. Warrilow

Masters Theses

Giving employees information about their performance is a common method for employers seeking to improve or change performance. With the popularity of the internet and computers feedback today is often provided through emails, text messages, and video meetings. While feedback has continued to evolve within and across organizations little has been done to assess the impact its delivery through various modalities has. This study explored and evaluated the relationship between the modality which objective feedback is delivered, and the differential effects it produced on performance of a check entering task. This experiment was a laboratory study employing a between-group repeated …

Anything But Race: Content Analysis Of Racial Discourse, Christopher Smith

Masters Theses

This research adds to previous scholarship on colorblind racism which investigates the ways in which students at Western Michigan University use new language compared to the Jim Crow past to defend or challenge the modern racial order in the United States. Using data collected from 15 voluntary participants I conducted a content analysis of participant’s responses to questions regarding race and racism with the purpose of demonstrating the use of colorblind racism or the challenge to the dominant racial order.

The Antipredator Behaviors Of Cryptic And Aposematic Anurans And Variability In Alkaloids, Conspicuousness, And Pattern Within Dendrobates Auratus (Dendrobatidae), Annelise Blanchette

Masters Theses

Crypsis and aposematism are common antipredator strategies that have evolved as defensive mechanisms to prevent predation. Prey that employ these defensive strategies also exhibit antipredator behaviors meant to avoid or deter predation. These behaviors include: (1) escape or immobility in the presence of an immediate predator or (2) exhibiting bold behavior by accepting the risk of potential predation in a novel environment in exchange for the benefits of foraging and mating opportunities. In this study, the escape and bold behaviors of cryptic members of Craugastor and the aposematic dendrobatid Dendrobates auratus were tested to compare these alternative antipredator strategies. Craugastor …

Satellite Sequencing Optimization And Observational Orbit Determination Using Genetic Algorithms, Andrew W. Verstraete

Masters Theses

The problem of mission design for a robotic servicing satellite in geosynchronous Earth orbit (GEO) was investigated. A representative set of potential client satellites was selected, and operational needs were randomly assigned based on the average number of GEO retirements, anomalies, and repositioning maneuvers that currently occur each year. An objective function was developed to represent the value of servicing mission sequences, including client fees, time penalties, and operational risk. A genetic algorithm was then used to find sequences of operations on the potential client set that maximized the objective function’s value. Scenarios were analyzed with the database of satellites …

The primary focus of this study is to analyze the effects of authoritative knowledge and biomedical interventions on women’s role within their reproductive process as it occurs within the US.I explore the technological advances surrounding childbirth practices within the United States and how through this technology, biomedical forms of authoritative knowledge of birth practices have developed and how these changes have benefitted as well as hindered women. Through interviews and interactions with mothers and pregnant women I evaluate how medical interventions emotionally and physically affect women; evaluate the necessity of increasing technological interventions as opposed to low technology midwifery assisted …

Guided By The Spirits: The Meanings Of Life, Death And Youth Suicide In An Ojibwa Community, Seth Allard

Masters Theses

Suicide is a leading cause of death amongst indigenous North American youth. The majority of studies on indigenous youth suicide focus on quantitative data collection and analysis. Qualitative and collaborative methods provide the cultural and historical contexts necessary for a critical understanding of youth suicide in indigenous communities. Through classic ethnographic methods (structured interviews, participant observation) and descriptive analysis, this work highlights the value of qualitative data. Medical anthropology informs an ethnomedical approach toward youth suicide, death, life, health and related concepts. Analyzing the semantics of prevention and intervention aids a critical-interpretive approach to current research and prevention-intervention frameworks and …

2-D And 3-D Mapping Of Soil And Rock Structure In Karst Terrain Of Southwestern Missouri Using The Non-Invasive Electrical Resistivity Tomography Method (Ert), Diya Ali Ahmad Alfuqara

Masters Theses

"Electrical resistivity tomography data were acquired in an extensively karstic area of southwestern Missouri. The interpretation of the electrical resistivity tomography data was constrained by multichannel analysis of surface wave data and limited boring control. The objective of the study was to determine if variations in the moisture content of the soil and shallow rock are related to ground surface topography. Analysis of the acquired electrical resistivity tomography data showed that resistivity values of soil and shallow rock beneath and in proximity to identified natural and man-made surface run-off pathways are typically low compared to the resistivity values of soil …

A Review Of Random Matrix Theory With An Application To Biological Data, Jesse Aaron Marks

Masters Theses

"Random matrix theory (RMT) is an area of study that has applications in a wide variety of scientific disciplines. The foundation of RMT is based on the analysis of the eigenvalue behavior of matrices. The eigenvalues of a random matrix (a matrix with stochastic entries) will behave differently than the eigenvalues from a matrix with non-random properties. Studying this bifurcation of the eigenvalue behavior provides the means to which system-specific signals can be distinguished from randomness. In particular, RMT provides an algorithmic approach to objectively remove noise from matrices with embedded signals.

Major advances in data acquisition capabilities have changed …

Masters Theses

"The development of renewable energy sources, such as biofuels, is of great interest in today's world due to depletion of fossil fuels and concerns about climate change. The production of the main by-product, crude glycerol, in biodiesel production presents an opportunity for the production of industrially relevant commodities. Crude glycerol in biodiesel waste is highly impure and possesses high salt concentrations and alkalinity, making it infeasible for direct industrial utilization. Moreover, current glycerol purification methods are highly cost-intensive, necessitating a search for cost-effective approaches that are feasible to employ. Genome data analysis of Halanaerobium hydrogeniformans, revealed the metabolic capability …

Investigating The Sources And Dynamics Of Escherichia Coli In A Missouri Ozarks Watershed, Kaleb Bassett

Masters Theses

"Escherichia coli, an intestinal bacterium, can serve as an indication of the presence of pathogenic microorganisms in water systems used by humans for recreation, agriculture, or drinking water. Many aquatic systems in the United States exceed the E. coli standard, set by the Environmental Protection Agency, for safe drinking water and recreational use. During 2016, a water sampling program was established in the Mill Creek watershed, a rural watershed located near the city of Newburg in Phelps County, Missouri. Water samples were collected before, during, and after storms throughout the year to examine the relationship between E. coli …

Evaluation Of Ecto-Mycorrhizae As A Determinant Of Chestnut Growth And Stress Response, Pabitra Aryal

Masters Theses

Although agriculture focuses on row crops throughout much of the Midwest, chestnut (Castanea spp.) appears to be an agroforestry crop well suited as a sustainable alternative to row crops in areas prone to erosion. As ectomycorrhizal (ECM) colonization is often crucial for tree establishment and production, I addressed the importance of ECM colonization on chestnut performance by assessing 1) natural ECM colonization in an established chestnut orchard and 2) the effect of experimental ECM inoculation on seedling establishment and drought response in a greenhouse. In the established orchard, I selected 50 Chinese-American hybrid chestnuts (C. mollisima x C. dentata …

Metabolic And Morphologic Shifts In Neuro2a Cells Cultured In Galactose Medium, Leah Welker

Masters Theses

It has been observed that highly-proliferating cells, such as cancer cells, rely mainly on glycolysis for ATP production, regardless of presence of oxygen. This effect, however, can be reversed by changing the main energy substrate in the medium from glucose to galactose. The oxidation of galactose in glycolysis yields less net ATP, presumably forcing the cell into OXPHOS. This has been established in many cell lines, including HeLA, HepG2, and skeletal muscle cells. As of yet, this has not been reproduced in neuronal cells. Using Neuro2a, a murine neuroblastoma cell line, this study exposes neuronal cells to galactose medium, and …

Red Emissive Bodipy Dyes As Sensitizers For Near-Infrared Emission Of Lanthanide Complexes & Structural & Spectroscopic Studies Of Quinoline-Functionalized Bodipy Dyes, Adedayo Ayodeji Kukoyi

Masters Theses

Bioimaging has become a significant tool for the visualization of biological events and the detection of numerous biomarkers. However, detection sensitivity is compromised by background signal from the biofluid which interferes with signals from the probes that usually emit in the visible region Alternative probes such as those that emit in the near-infrared (NIR) region are necessary to overcome these shortcomings. Lanthanide ions have demonstrated efficiency with sharp characteristic emission in the visible and (NIR) region. Emission however is mostly achieved by indirect sensitization process in which energy from the triplet state of a sensitizer is transferred to the excited …

Comparative Leaf Anatomy Of C3 And Cam Species In Oncidiinae (Maxillarieae, Orchidaceae), Samuel A. Eident

Masters Theses

The subtribe Oncidiinae is a diverse group of mostly epiphytic orchids within the tribe Maxillarieae, consisting of 55 genera and 1700 species. In this group, there have been many studies examining morphological and anatomical variation as well as metabolic pathways of carbon fixation, but most have not integrated morphological and anatomical variation with a physiological aspect of inquiry. The objective of my research was to establish a suite of anatomical characteristics that can be used to distinguish between C₃ and CAM species. Secondarily, I hoped to use that suite of characteristics in determining whether intermediate CAM species (those that …

Morphology And Variation In The Gargle Call In A Chickadee Hybrid Zone In Central Illinois, Shannon Marie Regan

Masters Theses

Black-capped (Poecile atricapillus) and Carolina Chickadees (P. carolinensis) have distributions that span the northern and eastern portions of the United States. The areas where these distributions meet are called contact zones and extend from Kansas to New Jersey. Contact zones often have a narrow range of hybridization and usually within these zones of hybridization we will see a mixture of genetic, morphological, and cultural traits. One focus of this project was to compare morphology and genetics of chickadees within and near the largest Illinois contact zone, which has not been done previously. This contact zone was …

Expression, Purification, And Characterization Of An Intrinsically Disordered Late Embryogenesis Abundant (Lea) Protein From Artemia Franciscana Utilizing Escherichia Coli And Nicotiana Tabacum, Md Fazlul Karim

Masters Theses

Anhydrobiosis is an astounding strategy that allows certain species (both animals and plants) to survive severe environmental conditions such as desiccation, extreme cold, or heat in the habitat. Despite the occurrence of several different molecular strategies, expression of highly hydrophilic polypeptides termed LEA proteins has been most conclusive identified as a requirement for the survival of plants and animals during periods of water stress such as freezing and drying. Several classification schemes for LEA proteins have been proposed and the brine shrimp, Artemia franciscana, is the only known animal that naturally expresses LEA proteins from three different classification groups …
