The Transcriptional Response Of Trametes Versicolor To Growth On Maple Chips And Miscanthus Straw, Maha Alanazi

Masters Theses

This thesis research explored the transcriptional response of Trametes versicolor, a white-rot fungus, in response to fundamentally different types of lignocellulosic biomass (miscanthus and maple) and rich medium (malt extract agar). After five weeks of growth by the fungus on the biomass, the fungal RNA was extracted from three biological replicates per biomass type and mRNA was sequenced (approximately 30 million reads per sample). The reads were processed using ArrayStar to covert to RPKM and annotated using JGI's T. versicolor GO annotation file along with NCBI's BLAST. Comparisons were made between average gene expression of the fungus grown on …

Chemotaxis Of Batrachochytrium Dendrobatidis Zoospores In Response To Live Amphibians, David Bartholow

Masters Theses

Batrachochytrium dendrobatidis (Bd) is one of the primary drivers of amphibian decline, and has spread rapidly on a global scale, but the mechanisms of Bd movement on small spatial scales are poorly understood and may play a role in transmission and infection. The flagellated zoospores of this fungus exhibit chemotaxis in response to single chemical cues, towards potential nutrient sources and away from metabolites of anti-fungal bacteria (AFB) present on amphibian skin. Levels of cutaneous AFB were manipulated on Eurycea bislineata hosts (either by bathing in a culture of the AFB Janthinobacterium lividum, or bathing in antibiotics) …

In addition, five themes were analyzed: Inconsistency of dietary intake, High cost of eating healthy, Post workout …

Groundwater-Surface Water Interaction In The Headwater Of The White River, Manistee National Forest, Michigan, Ziqian Li

Masters Theses

Groundwater is a significant fresh water source in most areas and can be affected by potential changes to climate and precipitation from anthropogenic influences. Considering groundwater and surface water can be regarded as one hydrologic system, it is significant to understand the dynamics between precipitation, shallow groundwater and surface water in order to manage these resources.

Water samples were collected roughly biweekly from July 2016 to June 2017, and analyzed for electrical conductivity and stable isotopes of oxygen and hydrogen. During sample collection site visits, stream discharge and the groundwater heads from different wells were measured.

The stable isotopes of …

An Ethnohistorical Study Of The Dowagiac Chieftains, Kathryn A. Bishop

Masters Theses

This research uses ethnohistorical methods to examine the use of imagery appropriated from American Indian cultures by the Dowagiac Union Schools. High School yearbooks from 1899- 2014, along with other artifacts, were identified as sources of information to describe students’ experiences. Applying Brayboy’s (2005) Tribal Critical Race Theory, an off-shoot of Critical Race Theory, combined with the research of historical and theoretical scholars like Davis (2002), Pewewardy (2001), and Deloria, King, and Springwood (2001), a case is made for the removal of American Indian mascots used by educational institutions, including the Dowagiac Chieftains. Though over 1,750 occasions of American Indian-appropriated …

Trading To Drink And Drinking To Trade: Assessing Alcohol Trade And Consumption In Seventeenth And Eighteenth Century New France, Cara A. Mosier

Masters Theses

Alcohol is one of the most misunderstood commodities used by both Native Americans and Europeans during the seventeenth and eighteenth centuries in North America. Although documentary sources are available, they can often provide conflicting information on the frequency of alcohol trade and its context of consumption. The archaeological record must be examined in conjunction with the primary and secondary sources to better understand alcohol consumption during this time. My research is conducted to answer the question: what patterns emerge when comparing the archaeological record to the documentary record concerning Native alcohol consumption in the seventeenth and eighteenth century fur trade …

Libya, The New York Times, And A Propaganda Model Of The Mass Media, Randy Laprairie

Masters Theses

This project derives a set of research expectations from the propaganda model, a structural model of the corporate news media developed by Edward S. Herman and Noam Chomsky. The model predicts that the news media will reflect elite views and priorities and marginalize views outside the range of elite opinion. Consequently, it is expected that the media will tend to support the elite’s preferred modes of exercising state power in international affairs. This often entails demonizing official enemies of the United States in order to justify military interventions while downplaying the crimes of the United States and its allies. To …

Architectural Representation And The Dragon’S Lair In Beowulf, Margaret Heeschen

Masters Theses

Since the early twentieth century, the dragon’s lair of Beowulf has been primarily associated with the early megalithic mounds of northern Europe. This interpretation of the space, however, does not account for the many contradictions present in the poet’s descriptions. In order to fully understand the quiddity of the dragon’s lair, we must resolve three major issues with previous interpretations: the use of rare words with unclear meanings, contradictions in descriptions of the physical space, and an assumption by scholars that the poet is describing a single type of space identifiable in the historical record. By addressing each of these …

Apan Production Through Photooxidation Of Isoprene In The Presence Of NoX, Timothy Glidewell

Masters Theses

Peroxyacyl nitrates (PANs, RC(O)OONO₂) are of great importance in atmospheric chemistry. They act as transporters of reactive nitrogen, and radical delivery agents. There are no known natural emission sources of PANs; they are produced through reaction of volatile organic compounds (VOCs) and nitrogen oxides (NO_x) in the atmosphere.

VOCs can enter the atmosphere through biogenic and anthropogenic pathways. It has been estimated that isoprene makes up 70% of the biogenic VOCs (BVOCs) emitted annually. Isoprene has been shown to impact ozone levels in both rural and urban areas by sequestering and transporting NO_x in the form …

Gradus Ad Parnassum: A Reader's Edition And Commentary, Sara Miller Schulte

Masters Theses

The seminal eighteenth-century counterpoint treatise Gradus ad Parnassum by Johann Joseph Fux exists in Latin, German, French, Italian, Spanish, and a host of other languages in its entirely, but in English only the second book of two has been translated, and even that is available only in a collection of partial translations. While a complete English translation is well beyond the scope of this project, toward that end, this research makes a case for its completion and provides a modernized edition and commentary of the as-yet-untranslated first book.

The Effect Of Auditory Stimuli On Test Performance: Testing The Arousal Hypothesis, Ian Thomas Kells

Masters Theses

Since the publication of Rauscher, Shaw, and Ky’s study in 1993 on the “Mozart Effect”, the study of music and its effect on cognition and performance has gained significant attention. Roth and Smith (2008) investigated this “Mozart Effect” and suggested a continuation of research and interpretation through an arousal theory. This study examined the effects of a subject-identified arousing stimulus on performance on the Verbal Reasoning portion of the GRE, analyzed through an arousal theory framework. A sample of 24 non-music Western Michigan University students took part in one 60-minute testing period using subject-preferred music, which was then analyzed across …

Finding A Baseline For Accountability In Diversion Programming, Anthony G. Frontiera

Masters Theses

This present study looked at a Mid-West American Juvenile Justice institution with the hope of helping to build a baseline of understanding in terms of how their diversion programming efforts are shaping out. Historically, research and funding have not been directed into diversion efforts in the same ways that re-entry efforts have seen. Studies have shown that if diversion efforts are not effective, then another cohort of youth are consigned to 50% higher recidivism rates than otherwise. The research before you was conducted to assist this institution in understanding and then changing their course of action with regards to diversion …

The purpose of this study is to validate a set of biomechanical finite element analyses against previously reported experimental results to predict the contact area and peak contact pressure in the lateral tibiofemoral compartment of the knee during lateral meniscal root avulsions in combination with MFL deficiencies. Patient specific MRI data was used to develop finite element models for three distinct testing conditions: 1) intact, 2) lateral meniscus posterior root avulsion, and 3) lateral meniscus posterior root avulsion with deficient meniscofemoral …

Life Among Good Women: The Social And Religious Impact Of The Cathar Perfectae In The Thirteenth-Century Lauragais, Derek Robert Benson

Masters Theses

This Master’s Thesis builds on the work of previous historians, such as Anne Brenon and John Arnold. It is primarily a study of gendered aspects in the Cathar heresy. Using inquisitorial registers from the mid-thirteenth century to the early-fourteenth, as well as a few poetic and prose sources, it seeks to understand how the Cathar “Good Women” were perceived by their lay believers. The methodology of prosopography is utilized throughout to measure witness testimonies against one another and to compare the connections between the Cathar constituency and the female ministers.

Two main inquiries are investigated: the sacerdotal and pastoral roles …

Enhancing Intersection Safety For The Blind And Visually Impaired (Bvi) Pedestrian Using Device-To-Infrastructure Communication, Mohammad Sayyah Al-Akash

Masters Theses

Visually impaired pedestrians have limited mobility options, where they rely heavily on walking and transit for their transportation needs. One of the major issues facing these pedestrians is intersection crossing. Accessible Pedestrian Signals (APS), as a means of helping their intersection crossings, were introduced in the United States as early as 1920 but were not included in the Manual on Uniform Traffic Control Device (MUTCD) until 2000. The most recent type of APS is the beaconing APS which has shown improvements in road crossing abilities of blind pedestrians though it has many downsides to it. This study developed a cane …

Overcoming Ideology: Examining The Tension Between Sex Work And Anti-Human Trafficking Advocacy, Emily R. Williams

Masters Theses

Human trafficking has become a national conversation and concern. Grassroots organizations designed to combat human trafficking spring up rapidly and help shape public perception on what trafficking is – and what it isn’t. Drawing on participant observation and indepth interviewing, I speak with anti-trafficking advocates determined to eradicate human trafficking and sex workers who prefer to stay in their profession. This thesis will largely explore the unintended consequences of well-meaning advocacy, and the tension between their views on the sex industry and the views from within the sex industry. I aim to use this work not only as a local …

Evaluating The Affective Impact Of A Place-Based Learning Course Project In The Geosciences, Nathan Charlton

Masters Theses

Coping with issues such as climate change and depletion of natural resources demands a scientifically literate public. For many students, the only exposure to earth science comes in a college-level general education geoscience course. One way to engender positive attitudes toward and interest in earth science among these students (the future public) is to connect learning to actual places to which students have a personal attachment.

This study seeks to evaluate the impact of a place-based learning project (MyPlace) currently in use in an introductory geosciences general education course at Western Michigan University. Students in the MyPlace project select a …

In this study, the effect of oil viscosity, experimental sample size, and step size were considered to see how they would affect the extracted skin-friction using the GLOF method. These results were then compared to published literature on skin-friction diagnostics of delta wings, based on observations of critical characteristics such as reattachment and separation lines. Delta wings of 50°, 55°, 60°, 65°, and 70° sweep angles were built and placed in the Small Wind Tunnel (SWT) at …

Papermaking Factors Affecting Lateral Web Position During Commercial Heat Set Web Offset Printing, George W. Shields

Masters Theses

The interaction of water with paper plays a role in web handling characteristics during commercial heat set web offset printing. Water absorption leads to lower web tension for a given strain.

This research investigates paper properties and their role in preventing lateral web movement from cross machine air flows in the drying section during normal printing operations. Tensile properties of sheets are measured at various moisture contents and then used to determine the equilibrium stress-strain relationship for papers at moisture contents typical of heat set web offset printing. Permeability, fiber orientation and tensile stiffness are evaluated against lateral web movement …

Surveying The Circular Rep Encoding Single Stranded (Cress) Dna Viral Consortium Found In Invasive Quagga Mussels (Dreissena Rostriformis Bugensis) And Sediments Of The Central Lake Michigan Benthos, Nicholas Gezon

Masters Theses

Globalization and resulting increases in international trade has allowed for the movement of species between almost all ecosystems on Earth. The Great Lakes in particular has seen a number of high impact invasive species that have moved in following the opening of the lakes to intercontinental shipping trade. This research specifically focuses on the benthic community of Lake Michigan which has seen significant community shifts including declines of the amphipods Diporeia spp. and the expansion of invasive quagga mussels (Dreissena rostriformis bugensis). Little is known about the viral community in the benthos of Lake Michigan and how …

Previous jumping studies have examined the role of arm swing in vertical and horizontal long jump performance, but none have been found which studied the role of arm swing in standing lateral jumps. The purpose of this study was to investigate the effect of arm motion on standing lateral jump performance and to examine the biomechanical mechanisms that may explain differences in jump distance.

A series of lateral jump experiments was performed for two jump cases (free and restricted arms) in which six participants jumped laterally for maximum distance from two in-ground force platforms. A motion capture system collected 3D …

Role Of Race/Ethniciy, Pre-Pregnancy Bmi, And Socioeconomic Status On Risk For Large-For-Gestational (Lga) Infants Born To Women With Gestational Diabetes Mellitus (Gdm), Anna M. Kiefer

Masters Theses

Background Fetal macrosomia occurs in approximately 10% of all pregnancies taking place in the United States. Babies born LGA are placed at a greater risk for shoulder dystocia, perinatal trauma, cesarean section, jaundice, hypoglycemia, and neonatal intensive care admission. Even more, the long-term impacts are severe and include increased risk of becoming overweight or obese and developing type 2 diabetes later in life. Women with gestational diabetes mellitus (GDM) have higher rates of delivering macrosomic offspring due to insulin resistance taking place beyond what is normal during a pregnancy. Additionally, maternal obesity, socioeconomic status, and race/ethnicity have been associated with …

The Effect Of Dietary Specialism And Generalism On Evolutionary Longevity In An Early Paleogene Mammalian Community, Samantha Glonek

Masters Theses

This study examines the relationship between relief index (RFI) on first and second mandibular molars and longevity of the genus. The molars were extracted from small-bodied, arboreal mammals during the late-Paleocene, early-Eocene in the Bighorn Basin in Wyoming. This study site is a well-known location to research and study fossil mammals of this time period. The study was conducted and analyzed at the genus level due to the relatively small number of specimens available and identifiable at the species level. Dietary breadth, or how broad or narrow a dietary preference is for a mammal, is an area of concentration within …

Query Expansion Techniques For Enterprise Search, Eric M. Domke

Masters Theses

Although web search remains an active research area, interest in enterprise search has waned. This is despite the fact that the market for enterprise search applications is expected to triple within the next six years, and that knowledge workers spend an average of 1.6 to 2.5 hours each day searching for information. To improve search relevancy, and hence reduce this time, an enterprise- focused application must be able to handle the unique queries and constraints of the enterprise environment. The goal of this thesis research was to develop, implement, and study query expansion techniques that are most effective at improving …

Brook Trout Behavioral Thermoregulation And Habitat Selection In A Small Michigan Coldwater Stream: Implications For Successful Management, Justin Emory Wegner

Masters Theses

Global warming and conversion of forests for urbanization, agriculture and mineral extraction are increasing water temperatures throughout Brook Trout’s range causing population declines; particularly in populations persisting in marginal habitats and in the southern limits of their distribution. The Brook Trout is an ectotherm that can cope with elevated water temperature by moving to coldwater refuge such as groundwater seeps, coldwater tributary confluences, and headwaters. Availability of coldwater refuge is vital for the survival of Brook Trout populations threatened by increasing water temperatures. I used radio telemetry to study the movement, habitat use, and behavioral thermoregulation of Brook Trout living …
