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 …

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 …

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 …

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 …

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, …

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 …

Best Practices For Differentiated Learning Among Third Through Fifth Grade Ell Students, Tara J. Macias

Masters Theses

With the increase of second language English learners in U.S. kindergarten through twelfth grade schools and the continued achievement gap between these students and English speaking students, educators and administrators need to develop, implement and support best practices for differentiation among English Language Learners. ELL students are often categorized as special education students while their only barrier to learning is language acquisition. On the other hand, ELL students may have additional learning difficulties that are not identified because there is an assumption that language acquisition is the single challenge to their learning. Educators often engage in whole group instruction with …

The Role Of Calcium In Regulation Of Glial Cell Line Derived Neurotrophic Factor By Skeletal Muscle Cells, Alicia M. Boynton

Masters Theses

Glial cell line-derived neurotrophic factor (GDNF) is an important signaling molecule for the somatic motor nervous system. GDNF protein is produced and secreted by skeletal muscle cells and helps maintain motor neuron innervation at the neuromuscular junction. Treatment with exogenous GDNF prevents denervation which is characteristic of aging and neurodegenerative disease. The therapeutic potential of GDNF cannot be fully explored without understanding the mechanisms by which GDNF protein production is regulated. The primary objective of this study was to determine the role of calcium in regulating GDNF protein expression by skeletal muscle cells. Skeletal muscle cells (C2C12) were grown in …

Divine Utilitarianism, Jimmy Lewis

Masters Theses

This work addresses the subject of God and ethics and aims to answer questions concerning why God does what he does and whether God is a utilitarian in his ethics. In order to answer these questions, God’s nature is explored through the lens of classical theists such as Anselm, Thomas of Aquin, and Augustine. Jeremy Bentham and John Stuart Mill’s conceptions of utilitarianism are also explicated so that there is no confusion regarding the definition of utility which is used in Divine Utilitarianism. Finally, Divine Utilitarianism is juxtaposed to Divine Command Theory and the explanatory power of each is considered. …

The Story And The Song: Examining Worship In The Tabernacle In Relation To The Gospel And Postmodern Evangelism, Debra Wilcox

Masters Theses

By examining tabernacle worship and its connection to the Gospel, worship leaders may find effective lyrical contexts for reaching the post-modern unbeliever. The priestly responsibility of the worship leader is to carry out the job description of helping people to worship God. As worship leaders select music for worship, they should take the opportunity to teach context and select songs that have parallels to tabernacle worship. In example, the significance of “entering into” worship is a reference to the high priest entering into the Most Holy Place. Worship pastors can approach the task of connecting postmodernists to God by examining …

The Modification Of A Curtain Coating Formulation: A Study Of Rheology And Surface Tension, And Their Effect On Pitting, Samantha Leigh Schoenfelder

Masters Theses

When an undisclosed recycled fiber mill installed a “two-slotted” curtain coater to replace their air knife coater, a prominent defect arose known as “pitting,” which is also called pinholing or cratering. Pitting occurs when the coating of the sheet has small holes that mar its surface, which, when clustered together or larger in size, can cause print breakup during the printing process.

Through research, pitting is known to be caused by a boundary layer of air that gets laterally pulled in between the coating and board during their initial contact. Thus, rheological properties and the surface tension of the curtain …

Flying Thru Security, Chelsea Bass

Masters Theses

Due to the Transportation Security Act (TSA), which passed in November 2011, airport security has drastically changed. The new security checkpoint practices have caused security lines to be very long; on average, a traveler waits 90 minutes to get through security. Most airline travelers frequently describe feeling anxiety, frustration, stress, and annoyance while in airport security lines. Being overwhelmed with time, pressure to move quickly and the overall security check process are also problematic for them as well as for the TSA officers and airlines. However, these emotionally negative travel experiences can become positive ones with some design element intervention …

Characterization Of Γ-Butyrolactone Rings: A Computational And Toxicological Study, Donald C. Kidd

Masters Theses

Given the declining state of the natural environment, identifying green methodologies in synthetic chemistry is becoming paramount. An under explored area of green chemistry, is the use of catalytic systems in green solvents. One interesting concept in green chemistry is the use of N-Heterocyclic Carbenes (NHCs) as organocatalysts.

Thiamine or vitamin B1 was one of the first NHCs recognized. Thiamine is required for carbohydrate metabolism and helps the cell produce adenosine triphosphate (ATP). Over the last 20 years NHCs have been found to be efficient catalysts in carbon-carbon bond forming reactions.

But to date, little research has been done exploring …
