Phosphorus Retention In West Michigan Two-Stage Agricultural Ditches, Emily Kindervater

Masters Theses

Input of excess nutrients into a water body can negatively impact ecological structure and function, as well as the economic vitality of surrounding communities, by contributing to eutrophication. For example, phosphorus (P) and sediment inputs from agricultural drainage have facilitated the development of hypereutrophic conditions in Lake Macatawa, a drowned river mouth lake located in Holland, Michigan. Two-stage ditches, an agricultural best management practice (BMP), are used in some areas of the Midwest to reduce N export downstream via denitrification. This BMP simulates a mini-floodplain by replacing a traditional, trapezoidal ditch with a channel that has excavated benches on each …

Masters Theses

The purpose of this thesis project is to assess the arousal hypothesis by implementing an auditory stimulus (music) at various times during a task (Verbal Processing section of the GRE) to analyze changes in arousal, as measured by electrodermal activity (EDA). Testing is administered for one hour with music implemented before testing and twice during testing. EDA levels are used to measure physiological response and are collected over the one hour testing period. For analysis, testing material is broken into different time blocks to assess arousal levels through mean slope, mean skin conductance level (SCL), mean skin conductance response (xSCR), …

The Influence Of Road Salt On Seasonal Mixing And Redox Stratification In Three Southwest Michigan Kettle Lakes, Danielle Dupuis

Masters Theses

Influxes of saline water from roads treated with deicers can alter the density structure of urban lakes. This can delay or halt turnover events, which may lead to persistent hypolimnetic anoxia in nutrient-rich lakes. In this study, the lake columns of two urban lakes (Woods Lake and Asylum Lake) and one rural lake (North Lake), were sampled once a month from March 2016 to June 2017. Lake column water was analyzed for conductivity, temperature, dissolved oxygen, ferrous iron, manganese, sulfide, calcium, magnesium, sodium, chloride and methane concentrations as a function of depth. All three lakes are eutrophic with anoxic hypolimnia …

Overcoming Hidden Shame To More Effectively Connect With God And His People, Colleen Lou Worrell

Masters Theses

This research project was designed to help Christians identify and overcome hidden shame so that they would be able to enjoy a more authentic connection with God and as an extension, to His people. I chose this topic because Christians are often seen by non-Christians as being judgmental, critical and unloving. This behavior does not reflect the transformation and behavior mandated in Romans 12 and other similar scriptures. Because these behaviors are sinful, the investigation began with a review of mankind’s first sin in the garden of Eden. Out of that review, I discovered that shame is commonly found alongside …

U.S. Metropolitan Bridges To Puerto Rican Music Identity; Cuban And Puerto Rican Music Connections From The 1920'S-1970'S, William George Johnson

Masters Theses

“Cuba and Puerto Rico are As two wings of the same bird, They receive flowers and bullets Into the same heart ...” (Lola Rodriguez de Tio, 1868) Puerto Rican poet and political activist Lola Rodriguez de Tio penned these words after being inspired by the call for the independence of Puerto Rico. Her words were further canonized in Puerto Rican cultural identity after being published in the song La Borinquena by composer Rafael Hernandez. Hernandez’s song would later become a musical symbol of national identity for the island of Puerto Rico and the Puerto Rican Diaspora. The connection between the …

Teaching Marching Band In Urban Schools, Freamon Mcnair Iii

The Development And Continued Evolution Of The American Style Of Oboe Playing, Rebecka Rose

Masters Theses

Though the American school of oboe playing did not exist roughly a century ago, its popularity and impact, in all of its variations, currently extends throughout and beyond the United States. Marcel Tabuteau, the founding father of the American school, developed a new and unique style during the early part of the twentieth century. This style became a truly hybrid school grounded in the French oboe school, and developed through his playing and teaching at the Curtis Institute of Music into a style that encompasses beauty, expression, and the vibrancy that has come to typify the American school oboist. The …

Bimusicality: Pedagogical Insights For Music Educators From "Second-Music" Learning Experiences, Kerry Digiacomo

Masters Theses

This study explores the development of “bimusicality” in adolescent and adult music learners to discover correlations between this experience and second language acquisition processes. North American music educators need to be equipped to help their students grow in their understanding of diverse musical styles, genres, and traditions, and the ethnomusicological concept of bimusicality, in connection with existing research on second-language acquisition as a sociocultural phenomenon, offers a new frame of reference for understanding how music learners may interact with distinct musical styles. Survey research with a group of 98 adult musicians, followed by ethnographic interviews of 16 of these survey …

Identification Of Deletions In The Hdc Gene Of Drosophila Melanogaster Generated Through Transposon-Excision Mutagenesis, Gregory A. Wesseling

Masters Theses

Histamine is a biogenic amine that functions as a neurotransmitter in a number of vertebrate and invertebrate systems and is synthesized from its precursor histidine by the enzyme histidine decarboxylase (HDC). In Drosophila, histamine has been shown to have function in photoreceptors, mechanoreceptor cells, as well as centrally located neurons. Mutations of the Hdc gene, such as Hdc^JK910, exhibit defects in histamine synthesis and display altered behaviors such as blindness, inability to groom, impaired thermal tolerance, and altered sleep rhythms. However, all Hdc mutants obtained thus far demonstrate some transcriptional activity.

In order to remove Hdc expression …

Reckoning: Detroit’S Literary Crisis Of Conscience, Danielle E. J. Cope

Masters Theses

Once the industrial heavy-weight of the twentieth century, the city of Detroit is now plagued by a narrative of decay that is made obvious by its abandoned and neglected buildings and neighborhoods. In sensational reporting about Detroit’s misfortunes, a reductive brush is frequently applied to paint the city into a “before” and “after” picture of “success” and “failure,” fetishizing its decay while often ignoring the countless ways that socio-economic forces contributed to its decline. Addressing the unresolved wounds of class discrimination and structural racism, authors Angela Flournoy and Michael Zadoorian have provided a literary space in which fictional Detroiters reckon …

From Subject To Cyborg: Reframing Identity Within Female Spaces In Neil Gaiman's Black Orchid And A Game Of You, Mary A. Ruge

Masters Theses

Whether they are secret or whether they are household names, identities are paramount in superhero comics. Yet those that create these identities do so from a place of privilege in a hierarchy which results in inauthentic characters and repetitive plots. For the superhero genre, the misrepresentation of female characters (perhaps related to a severe underrepresentation of female creators) has resulted in highly patriarchal storylines that are reductive, stereotypical, and often violent toward women. To combat this trend, one must consider the ways in which a more complex female character violates the current framework and offer a solution. For superhero comics, …

Yellow Perch Genetic Stock Structure In Eastern Lake Michigan: What Is The Importance Of Drowned River Mouth Lakes?, Gregory M. Chorak

Masters Theses

Habitat heterogeneity has the possibility of structuring populations. Even in connected landscapes, there can be cryptic structuring of populations that coincides with landscape features that limit gene flow or select for different phenotypes within a species. Yellow perch (Perca flavescens) is an economically and ecologically prominent fish in the Laurentian Great Lakes. In the Lake Michigan basin, yellow perch reside in nearshore Lake Michigan, including drowned river mouths (DRMs, lake-like habitats that link tributaries to Lake Michigan). The goal of this study was to understand whether yellow perch populations are structured in eastern Lake Michigan by the connected …

Polychlorinated Biphenyl Concentrations In Fish From Lake Michigan Tributaries And A Preliminary Risk Assessment Concerning Their Consumption By Sport And Tribal Fishermen, Amanda K. Potter

Masters Theses

Human and environmental health continues to be threatened by persistent organic pollutants in the Great Lakes ecosystem. Polycholorinated biphenyls (PCBs) are considered one of the most toxic contaminants in the Great Lakes due to their recalcitrance, bioaccumulation, lipid solubility, and adverse health effects.

The three main questions examined in this research were: 1) Do PCB concentrations vary between largemouth bass (Micropterus salmoides), northern pike (Esox Lucius), smallmouth bass (Micropterus dolomieu), and walleye (Sander vitreus) in west Michigan tributaries of Lake Michigan; 2) Do PCB concentrations vary on a watershed level among Manistee …

The goal of the research study was to understand how SES impacted the outcomes of children diagnosed with ALL, with a particular interest in children living in West Michigan. Children ages 0-14 years who received treatment for ALL at Spectrum Health’s Helen DeVos Children’s Hospital’s Pediatric Hematology and Oncology program between the years 2002-2011 were considered for this study. Eligible participant’s zip codes and dates of relapse/death were obtained …

Seasonal Ecology Of Mottled Sculpin And Brown Trout In A Coldwater Michigan Stream, Susanna K. Lagory

Masters Theses

In temperate regions, environmental conditions vary distinctly between seasons. This variation can strongly impact in-stream environmental conditions. Winter is often thought to be harsher than other seasons for stream fishes, given the adverse environmental conditions that arise from low temperatures during winter in temperate regions. Low temperatures, episodic elevated discharge, and ice formation associated with winter are hypothesized to reduce movement, body condition, and survival of stream fishes. However, few studies test this hypothesis through formal comparisons, and most studies of seasonal stream fish ecology focus on salmonids. To address this knowledge gap, I estimated and compared body condition, net …

The Effect Of Good Form Running Gait Retraining On Lower Extremity Kinematics And Ground Reaction Forces, Alyssa Schaefbauer

Masters Theses

Running is a popular activity for those trying to get in shape, stay fit, and improve overall health. As running has increased in popularity over the past couple of decades, so has the number of running related injuries. (Higginson, 2009; Statistics and Research, 2016). Interest in running gait research has also increased to address and understand the running related injuries. In addition to reducing injuries, the search for an optimal running form that will improve efficiency is being pursued (Davis, 2005). Good Form Running has become an increasingly popular school of running that seeks to fulfill these needs, but its …

Assessing The Potential Benefits Of Recreational Therapy On Functioning Outcomes, Samantha R. Lamkin

Masters Theses

Background: The aim of recreational therapy, like all rehabilitation therapies, is to promote the functionality and well-being of a person with disability. However, unlike other forms of therapy, recreational therapy utilizes a unique approach to rehabilitation by incorporating meaningful daily life activities into the patient’s individualized rehabilitation plan. Gains in functionality can be quantified using a Likert scale measurement Functional Independence Measures (FIM®). Previously conducted research shows a positive association between recreational therapy services and functionality gains in specific populations of persons with disability with stroke, traumatic brain injury, and spinal cord injury being most heavily represented. Problem: Research gaps …

The Role Of Affective Forecasting And The Impact Bias In Nutritional Health Behaviors, Matthew D. Fallon

Masters Theses

Previous literature on affective forecasting has studied its role in health decisions, but there is little research investigating affective forecasting in diet choices and eating behaviors. The present study collected affective forecasts from 43 college participants before eating an indulgent snack and then observed emotions immediately after eating the snack. We predicted that emotion predictions would be significantly stronger than observed emotions, in support of previous literature on the impact bias. We also predicted that optimism would predict a stronger impact bias and that extraversion and neuroticism would have a role in forecasts and observed emotions. Contrary to our hypothesis, …

Effects Of Aging And Dietary Phytoestrogens On Sperm Production In Sprague Dawley Rats, Brian Cutler

Masters Theses

Estrogens, in addition to testosterone, are physiologically relevant to normal sperm production in the testis and sperm maturation in the epididymis. Previous studies from our lab demonstrated that daily sperm production declines from 15 to 18 months of age in Sprague Dawley rats, and treatment with estrogen during this period attenuated the age-associated decline. Phytoestrogens are present in standard rodent diets at high levels (350-650 mg/kg) and may be potential endocrine disruptors. The purpose of this study was to investigate the effect of removing dietary phytoestrogens during aging on sperm production. Retired breeder Sprague Dawley rats were obtained at 9 …

Using Figurative Language In American English: Challenges And Successes Of Adult English Learners, Abbey L. Ventrone

Masters Theses

English language learners (ELLs) face many challenges when learning English. One of those challenges is the figurative language that is used in every day conversations. Often the lack of understanding or misunderstanding, can result in awkward conversations for English learners. This study aimed to identify what interpretations adult English learners at the advanced level give to American English figurative language and how do those interpretations differ or correspond to native speakers’ interpretations. This case study looks specifically at five adult learners from three different countries. The learners met once a week during the summer of 2016 to listen and interpret …

Nest-Site Selection And Neonate Survival Of Eastern Box Turtles (Terrapene Carolina Carolina) In Michigan’S Northern Lower Peninsula, Joseph T. Altobelli

Masters Theses

Turtles (Order Testudines) are experiencing global declines largely due to anthropogenic influences such as habitat fragmentation, illegal collection and sales, and the threat of global climate change. Removal of individuals from the adult age-classes means there is now a greater need to understand the survival of neonate and juvenile turtle age-classes. In this study I examined a population of eastern box turtles (Terrapene carolina carolina) at the northern limit of their range in Michigan’s lower peninsula. The objectives of my thesis were 1. to determine the microhabitat factors that influence nestsite selection by female box turtles and how …

An Analysis Of The Metal Finds From The Ninth-Century Metalworking Site At Bamburgh Castle In The Context Of Ferrous And Non-Ferrous Metalworking In Middle- And Late-Saxon England, Julie Polcrack

Masters Theses

This thesis opens with an investigation of the evidence for blacksmithing and non-ferrous metalworking in Anglo-Saxon England during the Middle- and Late-Saxon periods, c. 700-1066. The second chapter of this thesis focuses on knives and non-ferrous strap-ends during this period in order to discern any regional distinction in metalworking from the Anglo-Saxon kingdom of Northumbria. I initially conjectured that Northumbrian knives and strap-ends would show stylistic differences from knives and strap-ends made in other Anglo-Saxon kingdoms, but in this chapter, I conclude that Northumbrian metal objects were homogenous with the assemblages from the remaining kingdoms. In the final chapter of …

The values for the Buck-Boost circuit components, the capacitor and the inductor, are tuned and selected so …

A Study On The Impact Of Instruction Set Architectures On Processor’S Performance, Ayaz Akram

Masters Theses

The recent advances in different instruction set architectures (ISAs) and the way those ISAs are implemented have revived the debate on the role of ISAs in overall performance of a processor. Many people in the computer architecture community believe that with current compiler and microarchitecture advances, the choice of ISA does not remain a decisive matter anymore. On the other hand, some researchers believe that this is not the case and they claim that ISAs can still play a significant role in the overall performance of a computer system. Novel heterogeneous architectures exploiting the diversity of different ISAs have been …

Defining The Immune Response And Cellular Pathologies In Multiple System Atrophy, Annamarie Valenti

Masters Theses

Multiple System Atrophy (MSA) is a neurodegenerative disease characterized by the accumulation of misfolded α-synuclein (α-Syn) in oligodendrocytes of the central nervous system (CNS). A previous study in our lab used Affymetrix DNA microarray analysis to show the downregulation of various mitochondrial related genes, as well as the upregulation of genes involved in inflammatory/immune responses in MSA brain tissue. Therefore, it is hypothesized that an increased presence of immune proteins exists in the MSA brain accompanied by glial cell pathology including decreases in cell metabolism and cell viability. This study uses immunohistochemistry (IHC) to show the increased presence of CD68 …
