Living In A Gangsta’S Paradise: Dr. C. Delores Tucker’S Crusade Against Gansta Rap Music In The 1990s, Jordan A. Conway

Theses and Dissertations

This project examines Dr. C. DeLores Tucker’s efforts to abolish the production and distribution of gangsta rap to the American youth. Though her efforts were courageous and daring, they were not sufficient. The thesis will trace Tucker’s crusade beginning in 1992 through the end of the 1990s. It brings together several themes in post-World War II American history, such as the issues of race, gender, popular culture, economics, and the role of government. The first chapter thematically explores Tucker’s crusade, detailing her methodology and highlighting pivotal events throughout the movement. The second chapter discusses how opposition from rap artists, and …

Polycultural Interactions: Fuzzy Identity, Xi Lu

Theses and Dissertations

“Robin D.G. Kelley coined the term polyculturalism as an alternative to multiculturalism, ‘since the latter often implies that cultures are fixed, discrete entities that exist side by side—a kind of zoological approach to culture.’ ”

Polyculturalism assumes the whole world’s cultures are interactive and fluid instead of independent and static, and individuals’ relationship to cultures are complex and cannot be categorized. Yet an individual constitutes multiple cultures, and individual identity embraces the various forms of culture in all aspects of one’s life.

My research examines how polyculturalism affects aspects of communications among people who hold a multiplicity of voices. It …

Coloring The Square Of Planar Graphs Without 4-Cycles Or 5-Cycles, Robert Jaeger

Theses and Dissertations

The famous Four Color Theorem states that any planar graph can be properly colored using at most four colors. However, if we want to properly color the square of a planar graph (or alternatively, color the graph using distinct colors on vertices at distance up to two from each other), we will always require at least \Delta + 1 colors, where \Delta is the maximum degree in the graph. For all \Delta, Wegner constructed planar graphs (even without 3-cycles) that require about \frac{3}{2} \Delta colors for such a coloring.

To prove a stronger upper bound, we consider only planar graphs …

Applications Of Stability Analysis To Nonlinear Discrete Dynamical Systems Modeling Interactions, Jonathan L. Hughes

Theses and Dissertations

Many of the phenomena studied in the natural and social sciences are governed by processes which are discrete and nonlinear in nature, while the most highly developed and commonly used mathematical models are linear and continuous. There are significant differences between the discrete and the continuous, the nonlinear and the linear cases, and the development of mathematical models which exhibit the discrete, nonlinear properties occurring in nature and society is critical to future scientific progress. This thesis presents the basic theory of discrete dynamical systems and stability analysis and explores several applications of this theory to nonlinear systems which model …

An Exploration Of Factors Influencing Attrition From A Pediatric Weight Management Intervention, Melissa Ann Kwitowski

Theses and Dissertations

Childhood obesity is a serious health problem in the United States. Numerous weight management programs attempt to address this issue. However, attrition poses significant treatment efficacy challenges. Understanding attendance and attrition from childhood obesity programs is crucial for effective and appropriate resource utilization. NOURISH+ is a community-based treatment program for parents of overweight and obese children (age 5–11 years, BMI ≥ 85th percentile). The current study investigated attrition from NOURISH+ to enhance understanding of pediatric obesity treatment retention factors. NOURISH+ participants (n=70) completed a questionnaire assessing barriers to adherence and general program feedback. Data were analyzed using frequencies, …

Determinants Of Stress And Effects On Performance In Internal Medicine Residents, Sarah Braun

Theses and Dissertations

The purpose of the present study was to assess: a) perceived stress, burnout, depression, and empathy at three time points in internal medicine residents, b) the role of gender and trait mindfulness in stress response during residency and c) to evaluate the impact these variables have on performance evaluations. Additionally, specific tasks of the residency that may contribute to the experience of stress and burnout were evaluated to test a model of job strain. Stress predicted subsequent burnout and depression. Burnout predicted subsequent depression, and stress mediated this relationship. Women reported higher mean levels of empathy and burnout than men. …

Prediction Of Protein-Protein Interactions In Escherichia Coli From Experimental Data In Treponema Pallidum, Marco A. Abreu

Theses and Dissertations

Protein – Protein interactions (PPIs) are thought to be conserved between species, although this has not been systematically investigated. This problem was explored in Escherichia coli from experimental data in Treponema pallidum by predicting PPIs, focusing on protein domains of little or unknown function. The comparison of T. pallidum to a model organism such as E. coli can not only reveal additional data about T. pallidum but also reveals how E. coli is similar to this distantly related, obligate parasite. A set of novel T. pallidum interactions, enriched for proteins of unknown function, were the basis of over 23,000 predicted …

Hands On Painting, Matthew Yaeger

Theses and Dissertations

How can we know something through how it is sensed? Making anthropomorphic, three-dimensional paintings through a set of basic, at-hand materials, I’m interested in how empathy, modesty, and doubt can mediate a tangible experience of an object. Challenging notions of perception, I want to create a heightened sense of awareness in which the intangible can be seen or felt.

The Prevalence Of Dietary Supplement Use Among Older Adult Population Using National Health And Nutrition Examination Survey (Nhanes) 2009-2012, Fawaz M. Alotaibi

Theses and Dissertations

Background: Dietary supplements (DS) use has increased in the U.S. in the past 20 years. More than half of the U.S. population reported using DS. There are few studies to our knowledge that have assessed DS use specifically for older adults. In this study we purposed to evaluate the trend of using DS among older adults and to test the association between using DS and several demographics, socioeconomics and health characteristics. The second objective was to evaluate the reasons behind using DS among older adults using a nationally representative database.

Methods: This is a cross sectional study using the most …

Cute As A Button, Marta R. Finkelstein

Theses and Dissertations

Cute As A Button explores powerlessness, vulnerability, illness and addiction all wrapped up in tender buttons and a cute, cuddly creature. Using animation, sculpture, sound and an intimate space, I surround the viewer in a saccharine nightmare, one that references the dark underbelly of the cute and the sweet. The visual and aural elements are representative of the psychological and emotional states of powerlessness, which are overcome by the act of making and exploring a medium over which I can have complete control.

The Role Of Adam10, Adam17, And Spag6 In Humoral Immunity And Secondary Lymphoid Tissue Architecture, Lauren Folgosa Cooley

Theses and Dissertations

ADAM10, ADAM17, and SPAG6 contribute significantly to humoral immunity and secondary lymphoid tissue architecture. ADAM10 and ADAM17 are two closely related zinc-metalloproteinases. Through cleavage of their ligands CD23 and TNF, respectively, they greatly influence IgE production and secondary lymphoid tissue architecture maintenance. Th1 prone WT strains initially exhibit increased ADAM17 and TNF yet reduced ADAM10 relative to Th2 prone WT strains. In the absence of B cell ADAM10, a compensatory increase in ADAM17 and TNF cleavage is noted only in Th1 prone C57Bl/6, not Th2 prone Balb/c. B cell TNF homeostasis is important for maintaining secondary lymphoid tissue architecture. We …

Rituals, Our Past, Present & Future. Glimpses Of Islamic Enrichment, Othman Mohamed Khunji Mr

Theses and Dissertations

A Muslim should be encouraged to comprehend the benefit

and value behind every aspect of Islamic practice and wisdom,

and not just practice their religion because they were told to do

so. The products proposed in this thesis aim to achieve this by

inviting and encouraging a Muslim to practice The Five Pillars

of Islam while comprehending their value through the use of

modern means such as Arduino technology, 3D printing and

visual computing programing.

I am provoked by the fact that the circle of Gulf-region Muslims

I’m surrounded by, and have been exposed to since childhood,

belong to one …

Double Zero, Anthony Earl Smith

Theses and Dissertations

This thesis follows the trajectory of my artistic practice over the past two years, which has led to the installation of my thesis exhibition titled, Double Zero. I hope to position the work among its art and cultural terms by exploring how I have expanded my research concerning Situationist and Marxist theory as well as developed a broader photographic studio practice driven by material experimentation, play, and an investigation into how we live and interact with commodities through media.

The Orphanage Of Things: A Narrative Of Abandonment, Malaz Elgemiabby

Theses and Dissertations

In Sudan, 110 babies are abandoned in the streets of Khartoum every month. The majority of abandoned children are born out of wedlock. Young women with illegitimate pregnancies are often ostracized by their families and society, and the lack of emotional, financial and legal support has led many to take desperate measures, including the abandonment of their children. Relinquishing mothers exist like ghosts in Sudanese society. The only evidence of the mother’s experience is her anonymous, abandoned child. In order to understand and examine this phenomenon, I used ethnographic performance art informed by design research practice (Performative Research Design). I …

Thank You For A Lovely Time, Kelley Mj Morrison

Theses and Dissertations

Stemming from my own fixation on trying to understand the actions, decisions and thought processes of those around me my work explores the difference between internal and external lives. I construct “brain spaces”; whether my own or someone else’s I strive to understand the decisions they have made and the stories we are a part of. I combine thoughts, feeling and sentiments which I have collected over my life to make objects that act as intermediaries, allowing others to imagine stepping into a mind other than their own. I attempt to bring the landscape of the mind into the physical …

Privacy Protection On Cloud Computing, Min Li

Theses and Dissertations

Cloud is becoming the most popular computing infrastructure because it can attract more and more traditional companies due to flexibility and cost-effectiveness. However, privacy concern is the major issue that prevents users from deploying on public clouds. My research focuses on protecting user's privacy in cloud computing. I will present a hardware-based and a migration-based approach to protect user's privacy. The root cause of the privacy problem is current cloud privilege design gives too much power to cloud providers. Once the control virtual machine (installed by cloud providers) is compromised, external adversaries will breach users’ privacy. Malicious cloud administrators are …

Inhibition Of Mtor Signaling Protects Against Myocardial Reperfusion Injury, Acute Myocardial Infarction, Scott M. Filippone

Theses and Dissertations

Acute myocardial infarction (AMI) is the leading cause of death worldwide. Currently, the best method of treating cardiac ischemia is early reperfusion which, itself, induces myocardial damage. The mTOR complex is a key regulator of cardioprotection against cell stressors. We hypothesized that reperfusion therapy with Rapamycin, a potent mTOR inhibitor, would reduce infarct size in adult mouse hearts. Rapamycin was administered at the onset of reperfusion following 30 min in situ LAD ligation. After 24 hours of reperfusion, myocardial infarct size and apoptosis were significantly reduced in rapamycin-treated mice compared to control. Rapamycin inhibited pro-apoptotic protein Bax and phosphorylation of …

Cyclic Gmp: A Satiety Signal In C. Elegans, Ji S. Park

Theses and Dissertations

Appetite control and satiety mechanisms help animals maintain energy homeostasis; however, these mechanisms can be misregulated, leading to overweight and obesity. Caenorhabditis elegans is an excellent model system to study appetite and satiety because of its conserved behavioral aspects of satiety and conserved molecular mechanisms. ASI senses nutrition and its activity is required for the behavioral state of satiety quiescence. The purpose of this thesis project was to elucidate the function of cGMP signaling in ASI by looking at behavioral effects from the pharmacological use of sildenafil (Viagra), a PDE inhibitor, and the effects on ASI activation from mutating guanylyl …

A Continuous Process Towards The Synthesis Of Quinolones, Stevara N. Clinton

Theses and Dissertations

Abstract

The development of quinolones is described from the first quinolone to the latest fluoroquinolones. Quinolones have generated considerable interest since their discovery because of their antibacterial capabilities. Analogs incorporating the 4-quinolone ring system comprise a largely expanding group of synthetic compounds. The development of antibacterial resistance has created the need for an efficient synthesis of quinolones that can be easily adapted toward the assembly of quinolone based antibacterial drugs.

There are several reported approaches to the 4-quinolone ring system. Many of these methods use expensive starting materials, require the removal of high boiling solvents, or use high temperature conditions …

Lullaby, Amber M. Smith

Theses and Dissertations

I have been investigating the way in which my mind has altered my memories, especially from childhood. The more a moment is recalled, the less precise it becomes. The most inaccurate memories from childhood are the ones I have fixated on. Bedrooms are spaces where dreaming, sleeping and reverie take place leading to even more fragmenting. The intimate space of a bedroom allows me to represent the personal distorted recollections. The bedroom furniture is missing parts, shifted in height and placement or combined together. By making doubles of furniture, a direct comparison can be made from the real piece to …

Postcession, Evan D. Pomerantz

Theses and Dissertations

This is a series of daily writings. Each day consists of a new topic and is closed at the end of the day. The ideas presented are philosophical, humorous, rambling, lamentations, incantations, doubt-ridden, aesthetic pep talks which combine into an affective representation of my studio practice’s becoming. There will be little congruency, some stories, and a lot of parallels because that is who I am.

Tracing Motion, Stephanie M. Clark

Theses and Dissertations

This document explores the use of motion within design to defamiliarize a message. The objective is to expand a viewer’s level of understanding through prolonged perception. I experiment with this idea using present-day tools which afford my own movement during the capturing process to create various visual interpretations of motion. I look to László Moholy-Nagy, Aleksandr Rodchenko and Eadweard Muybridge who explored the use of the camera, the new technology of their day, to understand its potential to create a new visual language. They believed the lens of the camera was the eye of the future—and the public’s exposure to …

Surface Photovoltage Transients For P-Type Algan, Karen L. Phumisithikul

Theses and Dissertations

There is an understanding of surface photovoltage (SPV) behavior for GaN, yet little is known about the SPV behavior for AlGaN. In this work, a Kelvin probe was used to measure the SPV for p-type AlGaN. Very slow SPV transients were found in AlGaN, which could not be explained with a simple thermionic model. A possible explanation of this behavior is the segregation of impurities to the surface, which causes significant reduction of the depletion region width (down to 2 nm), with carrier tunneling and hopping becoming the dominant mechanisms responsible for the SPV transients. To verify this assumption, …

Place-Based Scholarship Program Design, Context, And Intergenerational Mobility: A Case Study Of The Kalamazoo Promise Scholarship Program, Arielle F. Niemeyer

Theses and Dissertations

Earning a college degree correlates with achieving financial security. Thus, improving an individual’s access to college is a key tactic used to mitigate poverty and foster intergenerational mobility. Despite the recognized value of higher education, earning a degree remains unattainable for many because of financial constraints. However, research definitively demonstrates that financial aid overcomes that obstacle. It also reveals that some program designs are more effective than others. The Kalamazoo Promise is a place-based scholarship program that offers four-year, full-tuition scholarships to residents who graduate from a Kalamazoo public high school. It is characterized by first-dollar and universal eligibility features, …

Investigation Into The Specification Of Nurf Recruitment To The Genome, Marissa Mack

Theses and Dissertations

The nucleosome remodeling factor (NURF) is a mutli-protein complex that plays a role in the regulation of gene expression through its ability to remodel nucleosomes. The largest subunit of this complex, Bptf (Bromodomain PHD Finger Transcription Factor) is important for many cellular processes as a transcriptional regulator and improper function results in disease or malignancy. To further understand the genome-wide recruitment of the NURF complex, the interaction partner for the N-terminal PHD finger domain of Bptf was investigated through pull down assays followed by mass spectrometry. It was determined that this domain does not recognize histones; instead it recognizes a …

Virsa: The Contemporary Value Chain, Samreen Zahra Mrs

Theses and Dissertations

"Handicraft" means a useful or decorative object made by a craftsman who has direct control over all stages of production. Handicrafts have always had a greater value, an identity of their own that is reflective of their place, culture and materials, as well as a sense of belonging to a particular place and time. With the ever-growing mass production that followed the Industrial Revolution, we lost those crafts to multiple reasons: one being cheaper, industrial-made products reducing the demand for handicrafts, and another being a shift in consumer tastes. Most craftspeople hardly earn enough to survive and fulfill their basic …

Reconstructing A Science Fiction Autobiography, Jason R. Rood

Theses and Dissertations

This is a collection of essays revolving around concepts pertinent to my current visual arts practice, centering on a deconstruction of personal narrative mythologies. What is generated is a web of connection that spans Narrative Modes, Science Fiction, the use of Lines and Drawing, the Digital and Space and Time. Through this interweaving of topics, I am beginning the process of rebuilding the structure of a personal story for the future.

One Script, Two Perspectives: Generation Me And The Staging Of Really Really, Kirstin R. Hensley

Theses and Dissertations

Really, Really, by Paul Downs Colaizzo, is loosely based on the 2006 Duke University sexual assault scandal resulting from what proved to be a false accusation of rape made against three members of the men’s lacrosse team. After individually reading the play, Jorge Burmudez and I both arrived at differing opinions of who was the true victim, in turn inspiring this thesis, which is an exploration of two separate productions of the play demonstrating contrasting perspectives/outlooks regarding sex crimes within sports organizations in the university setting. It will describe our process from conceptualization to a post-mortem talking about particular …

Curiosity And Compassion: Curiosity And Attachment Security's Relationship With Empathic Responding To Hardship, Athena H. Cairo

Theses and Dissertations

Compassion requires both attention and motivation to engage with another person’s experience. Two studies examined whether curiosity—the interest and motivation to explore new or complex information—promotes empathic concern and suppresses personal distress. These studies also examined whether attachment insecurity moderates curiosity’s effect on empathy. Study 1 identified correlations among curiosity, attachment security, empathic concern, and personal distress traits. In Study 2, participants were primed with high or low curiosity before watching a video of a peer experiencing hardship, then reported state curiosity, empathic concern, personal distress, and prosocial motivation. Trait and state curiosity predicted greater empathic concern and prosocial motivation. …

The Object Inbetween, Lucy L. Derickson

Theses and Dissertations

My mission is to bring attention to the unusual, undefined, and fluid connections we have to objects through various avenues of experience. Things, objects, and devices have shaped our culture, environment, and personal philosophies. We live, grow, learn, and mourn with objects. We worship, sympathize, and relate to objects. But what I am most interested in is a human tendency to retreat to objects, allowing them to mediate experiences of friendship and intimacy between people.

During my graduate studies, I have been evaluating my personal and professional connections with others in order to understand how technology such as smart phones …
