Assessing A Byproduct Of The Cbd Ethanol Extraction Process For Potential As A Wood Finishing Product, Avani M. Flanagan

Masters Theses

Developments in regulations concerning the use of CBD products as therapeutic remedies have allowed the global cannabidiol (CBD) market to take off within the past five years. Despite producers of CBD oil wanting to optimize their methods and increase product yields, several waste streams still exist. During the winterization phase of the ethanol extraction process, CBD oil is cooled and filtered so the fats, waxes, and lipids from the Cannabis sativa plant can coagulate and be removed, creating a purer oil with higher potency but contributing to the 58% (crude weight) total loss that occurs throughout the process. The removed …

Development Of A Chemical Biology Approach To Uncover The Influence Of Sequence Variations On Ces1 Activity In Live Cells, Samuel James Knebel

Masters Theses

Drug metabolism is the biochemical process of modifying drugs to detoxify and remove them through enzymatic transformations. These biotransformation’s occur primarily in the liver and are critical to understanding how pharmaceutical compounds are chemically altered inside the human body. Human carboxylesterases (CESs) catalyze the hydrolysis of esters, amides, thioesters, and carbamates. CES-mediated hydrolysis plays an important role in the metabolism of many drugs including the first FDA approved antiviral treatment for COVID-19, remdesivir (Veklury), the seizure control medication rufinamide (Banzel), and the flu antiviral drug oseltamivir (Tamiflu). CES activity is known to be influenced by a variety of factors including …

Wolbachia Infection In Gall Associated Insect Communities In Illinois And Indiana, Jakeb Watts

Masters Theses

Wolbachia is a maternally inherited, gram-negative bacterium and has been found to be associated with up to 60% of all insects, frequently resulting in male-killing, feminization, and cytoplasmic incompatibility in the hosts. Gall wasps and other gall-forming insects induce on various host plants abnormal tissue growths, or plant galls, with distinct morphology. They are considered as obligatory parasites to their host plant. The presence of Wolbachia infection in gall wasp populations in North America has not been extensively documented. Given the strong influence on host reproduction, not knowing Wolbachia infection in insect populations prevents the understanding of how populations are …

Triclosan Degrading Bacteria From Wastewater Treatment Plants In Central Illinois, Mohammed Alsulami

Masters Theses

Triclosan is an antimicrobial agent that has been used in personal care products and has been identified to cause malformation on cartilage and bone development in zebrafish and influence on thyroid hormone system in humans. Due to its widespread usage and insufficient removal from wastewater treatment plants, triclosan has emerged as a pervasive contaminant that poses a potential threat to the environment and human health. The goal of the study was to isolate and characterize triclosan-degrading bacteria from WWTPs in central Illinois. Using enrichment culture with NMS media containing triclosan as sole carbon source, eighteen bacterial strains were isolated. The …

Predictors Of Attitudes About Autism Spectrum Disorder (Asd), Claire Sullivan

Masters Theses

Students with Autism Spectrum Disorder (ASD) are far less likely to enroll in secondary education than neurotypical students and students with disabilities (White et al., 2016). There is little research on the factors contributing to the reluctance of young adults on the autism spectrum to seek higher education. This study aims to answer two research questions. The first research question aims to determine if there is a predominance of negative attitudes towards ASD amongst present undergraduate college students. The second research question explores whether this could be a determining factor in a college determination for students with ASD. This current …

The Influence Of Cover Crops On Grassland Restoration, Josh C. Poland

Masters Theses

Grassland ecosystems comprise almost a fourth of all Earth’s land mass; however, due to ever-increasing rates of agricultural land conversion, these habitats are facing a large-scale biodiversity crisis. The degradation of grasslands extends beyond physical impacts, such as soil erosion, to include the loss of soil microbial communities as a serious risk to the health and productivity of these habitats. Cover cropping, commonly used in agriculture to revive agricultural soils, has rarely been applied to grassland restorations, and could combat or reverse the harmful effects of modern agriculture techniques. For the first chapter of my thesis, I used a greenhouse …

A Survey Of Diatom Assemblages Of North Dakota: Identification, Enumeration, And Assessment Of Stream Health With Environmental Variables, Cole Tilford

Masters Theses

Diatoms have been used as biological indicators for assessing the environmental health of waterways for over a century. Their low motility and responsiveness to environmental changes makes them ideal for this purpose. North Dakota oil extraction has undergone a massive transformation as hydraulic fracturing across the Bakken Formation and the Williston Basin has increased over the last 20 years. Hydraulic fracturing increased the potential for environmental pollution of North Dakota’s waterways, especially in the form of highly saline hydraulic fracturing liquid. Many North Dakota streams are already saline and additional salinity could cause drastic changes in aquatic ecosystems. North Dakota …

Species Responses To Habitat Edges And Fragmentation Per Se: A Cross Taxa Meta-Analysis, Rachel Snyder

Masters Theses

Aim We examined the scale equivalency of fragmentation effects at the patch scale and landscape scale to determine if patch level effects scale up to landscape level effects. First, we examined species responses to fragmentation effects at the patch scale and landscape scale. Second, we evaluated whether there is a difference in response between taxonomic groups and across latitudes. Finally, we analyzed the data at the level of individual species in order to determine how species respond to edge effects and fragmentation effects. Location Data for 71 studies were gathered from the BioFrag database. Studies used were located in 48 …

Board Games: A Perfect Match For Reading Comprehension, Christopher Allen Frazier

Masters Theses

Analog board games greatly benefit students’ development and overall well-being. Board games offer opportunities for early learning, help boost language skills, sharpen students’ ability to focus, teach the value of teamwork, and soothe anxiety. Integrating board games with literacy skills allows students to assimilate information and develop into lifelong learners. Without solid literacy skills, the future is bleak for most students. To compound the problem, a trend today is to replace traditional board games as an educational tool with digital alternatives. This trend has seen a downward correlation with students having significant reading deficiencies in their reading comprehension in grades …

Is The Kalam Cosmological Argument's Second Premise Defendable?, Mark Karapetyan

Masters Theses

Contrary to the skeptic's rejections, the second premise of the cosmological argument can be defended via scientific and philosophical arguments.

Bibliotherapy In The Helping Professions: A Heuristic Model For Intervention Design, Natalie Marie Haney

Masters Theses

I propose a new approach to examining bibliotherapy’s usefulness in the community-based care of individuals with serious mental illness (SMI), focused on producing a heuristic that benefits helping professionals who offer non-clinical and non-psychiatric services. Meant for writers designing bibliotherapy interventions in the helping professions, I conceptualize bibliotherapy in a model against the backdrop of community-based care’s history. A model has the potential to allow each writer to conduct situation-specific inquiry, invent bibliotherapy intervention designs suited to the unique needs of the profession’s help-seekers, and reflect on knowledge generated for intervention reiteration. Referring to Dewey, Rosenblatt and Barnlund to create …

Relationships Among Age, Relative Telomere Length, And Dna Methylation In Pteropus Bats, Erika E. Forest

Masters Theses

Bats are the longest-lived mammalian order relative to body mass, but questions remain about relationships among mechanisms related to aging. Relative telomere length (rTL) decreases with age in most mammals, but the relationship between age and rTL is highly variable among the few bat taxa studied to date. More recently, DNA methylation (DNAm), a type of epigenetic regulation in which methyl groups are added to cytosine-phosphate-guanine (CpG) sites across the genome, has been shown to be highly predictive of age in many species of bats. We examine the relationships among age, rTL, and DNAm in Pteropus pumilus and P. hypomelanus …

Benthic Macroinvertebrate Pre-Assessment Of A Proposed Restoration In The Grand River, Grand Rapids, Mi, Usa, Matthew L. Bain

Masters Theses

River restoration is the dominant field of applied water resources management in the United States. Ecological improvement should be the goal of all river restorations, though many restoration projects fail to produce positive results due to limited scope or inadequate assessment methodologies. Pre-restoration, biotic data is essential for such projects as it can be paired with post-restoration data to gauge ecological outcomes. A major restoration effort is now underway in Michigan's longest river, the Grand River, where it flows through downtown Grand Rapids. The primary restoration measures will occur in-stream at local scale. We conducted a pre- restoration survey for …

“The Ugly Truth”: Examining War Trauma And Therapeutic Storytelling Through The Works Of Tim O’Brien, Meredith Ivy Fedewa

Masters Theses

Within this work, a close study on the relationship between trauma and storytelling is examined through three of Tim O’Brien’s works: The Things They Carried, Going After Cacciato, and In the Lake of the Woods. Through the application of psychoanalysis, specifically the work of Jacques Lacan, and modern trauma theory, the relationship between individual identity and the traumatizing encounter of the Real is examined through O’Brien’s concepts of Story Truth versus Happening Truth, as well as how those concepts work together to navigate one’s trauma story. Through weaving the aforementioned theory with each text, O’Brien is seen …

Beyond All Worlds: George Macdonald, The Pre-Tolkienians, And The Forgotten Possibilities Of Fantasy, Ethan Patrick Stevens

Masters Theses

The history of modern fantasy has been powerfully shaped by the worldbuilding paradigm so successfully executed in J.R.R. Tolkien's 1954-55 trilogy The Lord of the Rings. However, there were nearly a hundred and fifty years of creative work between the birth of fantasy as a genre and Tolkien’s publication of The Lord of the Rings. By examining the pre-Tolkienian fantasists, we find that Tolkien's way of exhaustive consistency was not, and is not, the only way to write fantasy. Phantastes (1858), the first novel by the influential Victorian fantasist George MacDonald, defies contemporary worldbuilding standards almost constantly in …

Suicide At The Intersection Of Race And Gender, Marina Geider

Masters Theses

Sociological studies have examined suicide rate differences between groups since the work of Durkheim in 1897, and current literature still draws on his classic theories and methods. Although research has begun identifying the social factors that affect the suicides of Black and White populations differentially, little progress has been made towards an understanding of Black female suicide. The present study takes an intersectional approach to Durkheim's social integration-regulation thesis to bridge this gap. Several negative binomial regression analyses were employed to model suicide counts for Black men, Black women, non-Hispanic White men, and non-Hispanic White women in the United States. …

Wood Turtle (Glyptemys Insculpta) Spatial Ecology, Habitat Selection, And Use Of Restored Oak-Pine Barrens In Northwestern Michigan, Diana Paige Methner

Masters Theses

Habitat fragmentation and loss, predation, and illegal collection are among the many threats plaguing turtle species worldwide which have caused substantial population declines. In the United States and Canada, approximately 38% of turtle and tortoise species are under significant threat. The wood turtle (Glyptemys insculpta) a freshwater turtle species experiencing declines and in 2023, the U.S. Fish and Wildlife Service will determine if this species should be listed under the Endangered Species Act. We studied the spatial ecology of wood turtles in northwestern Michigan, USA to fill knowledge gaps that exist throughout their geographic range. Between May 2021 …

The Effects Of Deleting Lrb E3 Ligase Region 2 On Red Light Responses In Arabidopsis Thaliana, Sabina Liskey

Masters Theses

The ability of plants to absorb light through photoreceptors is essential for successful plant development. Phytochromes are important plant photoreceptors that detect and absorb red and far-red light and must function properly for plant survival. The Light Response BTB proteins (LRB) play an important role in a plant’s response to red light by degrading phytochrome B (PhyB) via the ubiquitin proteasome system (UPS). Although there has been a successful investigation into understanding the function of the LRBs, the function of a few regions within LRB proteins remains unknown, including a portion located on the N-terminal end of the protein, termed …

"The Missus Has Paid For Your Life.": Preconstituted Third-World Women In Chris Cleave's Little Bee, Jeanette P. Barry, Jeanette Parry Barry

Masters Theses

In “Under Western Eyes,” Chandra Mohanty explains how some Western feminist scholars unconsciously other third-world women by imposing on them their Eurocentric universality. Using Mohanty as a primary lens, this thesis argues that in Chris Cleave’s Little Bee (2008), the protagonists, Sarah and Little Bee, are respectively represented as a Western referent and a third-world preconstituted woman, rendering any true collaboration between them impossible. Little Bee is meant to enlighten its readers of the plight of refugees in the United Kingdom, and in some ways it does just that. Little Bee also, however, situates the English protagonist Sarah as a …

Running Out Of Oxygen: Revealing The Interannual And Intra-Annual Dynamics Of Bottom Water Hypoxia In A Great Lakes Estuary Using Time-Series Observations, Experiments, And Analyses, Nate M. Dugener

Masters Theses

Bottom water hypoxia, a condition of low dissolved oxygen in the bottom waters, negatively effects lakes and freshwater and marine coastal estuaries globally. As climate change shifts climatological and ecological patterns, hypoxia continues to shift in duration and severity. In Muskegon Lake, Michigan, hypoxia occurs annually, restricting fish habitat, increasing cyanobacteria blooms, and disrupting ecological and socioeconomic prosperity. In the current study, we examined the duration and severity of hypoxia over a 11 years (2011-2021) utilizing data from the Muskegon Lake Observatory buoy (MLO, https://www.gvsu.edu/wri/buoy/). During 2021, we analyzed the dissolved oxygen (DO) concentrations observed by the MLO, conducted biweekly …

Developing Biblical, Community-Based Resources For Military Wives Entering The Empty Nest And Midlife Transition Period, Cynthia Louise Stumme

Masters Theses

Military wives approaching the onset of middle age and the empty nest should have access to resources that help them navigate the challenges of midlife within the context of the military lifestyle. The US military provides resources supporting successful family relationships for almost every other demographic except for military wives at the midlife and empty nest stage of life. While midlife is understudied as a life stage, the existing research does identify specific objectives for personal development and growth during middle age which lead to thriving in that stage and in old age. Using these objectives as a guide, this …

Stravinsky's Symphony Of Psalms Compared With Burton's Psalms Symphony, Roberto L. Burton

Masters Theses

"Stravinsky's own account of the composition of this great work follows and needs no addenda. But since composers don't always point out their greatest masterstrokes, here are a few additional comments. Listen closely to the first chord it recurs several times during the opening minutes of the first movement for although it is a simple e minor triad, in Stravinsky's hands even a conventional chord becomes distinctive. In assigning the triad's notes to the instruments of the orchestra, Stravinsky hands out twice as many G’s (minor triads) as the root of E or the fifth of B, contrary to what …

Effective Environmental Education: The Way To A Greener, Brighter Future, Amber Leanne Bailey

Masters Theses

Green spaces provide many benefits to local communities, including improved mental and physical health and stronger, safer communities. They also provide sustainable ecosystems for wildlife. These benefits provide a better quality of life for the people in the community. However, some communities cannot experience these benefits due to a common issue among green spaces: degradation in the forms of littering and vandalism. Despite efforts in environmental education, this problem persists. The aim of this project is to contribute to keeping green spaces greener. To study potential solutions for the continued degradation, an analysis of relevant literature is conducted on the …

Potential Impacts Of Hemlock Woolly Adelgid Infestation On Forest Overstory And Avian Assemblages In West Michigan, Usa, Nathaniel Sq Wagner

Masters Theses

Invasive species threaten the health and resiliency of native ecosystems wherever they are found. The damage caused by invasive species often leads to a cascade that degrades the ecosystem as a whole. In eastern North America, the invasive insect, hemlock woolly adelgid (Adelges tsugae; HWA), threatens the continued existence of eastern hemlock (Tsuga canadensis) and the species that are associated with it. Often considered a foundation species, eastern hemlock influences the structure and composition of eastern forests by lowering soil temperature, subsequently raising soil moisture content. In the absence of hemlock, many forests become dominated by …

Using Plot Photographs To Estimate Tundra Vegetation Cover In Northern Alaska, Hana Christoffersen

Masters Theses

Plot photography can provide a quick, robust method to measure vegetation, especially in polar environments where logistics can be expensive and challenging. The success and widespread adoption of plot photography in the Arctic hinges on the accuracy of image analysis and data product interpretation. The relative cover of eight vegetation classes was estimated using a point frame and digital camera across thirty, 1-m² plots at Utqiaġvik, Alaska from 2012 to 2021. Geographic object-based image analysis (GEOBIA) was applied to generate objects and classify the three band (red, green, blue) images.

Defending The Resurrection Of Jesus Through The Reliability Of The Credible Witnesses, Gregory K. Cherven

Masters Theses

The purpose of this thesis is to illuminate the fact that there is sufficient evidence for the resurrection of Jesus Christ through the reliability of the credible witnesses. Although physical evidence is lacking, it does not mean there is not sufficient evidence. Is it necessary to have physical evidence to secure a conviction? Criminal cases will be explored in which murder convictions were secured without the recovery of a dead body, physical evidence, or a confession. The convictions were secured based solely on witness testimony. The eye-witnesses of the resurrection of Jesus are evaluated through a modern lens and there …

Comparative Anatomical Study Of The Brachial Plexus Of Primates, Alison Leann Camero

Masters Theses

Old world monkeys, new world monkeys, and humans all originate from a common ancestor. Although humans and old world monkeys are phylogenetically more closely related, old world monkeys and new world monkeys have similar locomotion. A difference in muscle patterns exists between old world monkeys, new world monkeys, and humans. Different musculature may be due to differences in locomotive patterns and species-specific use of their forearms. Muscles in the forelimbs are innervated by the nerves of the brachial plexus. There are differences among the brachial plexuses of human and non-human primates as well as variability within the species.

Civic Virtue In America During The Gilded Age, Daniel Gregory Lundstedt

Masters Theses

This study will seek to reevaluate the era which historians have traditionally labeled as the Gilded Age. It will do this through an examination of the state of civic virtue in the United States during this period. This will be accomplished through an interdisciplinary foray into America’s past. From it, hopefully some fresh understandings of what America is, and where it is going, can become apparent. This project falls within the broader exploration of the relationship between the citizen and society and will thus hopefully contribute to that set of literature. This project will be a convergence of several subdisciplines …

Taking Aim: The Evolution Of Women In Competitive Shooting Sports In The 20th Century United States, Alena Rose-Marie Buczynski

Masters Theses

Throughout history, women have been overlooked, discounted, and ignored for their skills and abilities as competitive and professional athletes. Competitive shooting sports were popular in the United States; however, men excluded women from participating in many of these activities until the early 19th century, when America saw the rise of famous markswomen such as Annie Oakley, Calamity Jane, and Lillian Smith. These women challenged the masculinity of the sport of shooting and bested many of their male counterparts as they traveled and performed across the United States. In the 1970s, women found themselves entering the Olympic arena of competitive shooting …
