The presence of interstate highways in rural areas improves access to nearby rural

communities and changes those communities’ spheres of influence. Research into

understanding how improved access from interstate highways affects rural communities

is needed. This case study was designed to investigate how rural communities changed

on the basis of population, vacancy, median home value, and median contract rent in the

short term after an interstate highway was completed nearby in the early 1990s.

The communities included in this study are incorporated cities, towns, villages

and census-designated places in non-metropolitan counties with at least one incorporated

city, town, village and …

Contesting Consent: Consent, Sexual Scripts, And Gendered Power, Julia Kristine Metz

Graduate Research Theses & Dissertations

Within the past decade, the United States has seen an upsurge of affirmative consent policies being introduced or passed within the legislation of state governments and universities (Laker and Boas 2015). However, in a moment when the President of the US has been recorded saying “Grab ‘em by the pussy,” two Supreme Court justices have been accused of sexual misconduct, and a Secretary of Education has rolled back Title IX policies that had made progress in curbing sexual violence in schools, the meaning of sexual consent is now being contested more than ever. However, there have only been a handful …

Trauma Memory: The Role Of Alexithymia And Emotion Regulation, Jennifer Milliken

Graduate Research Theses & Dissertations

Alexithymia is a clinical term used to describe individuals who struggle to connect to their emotional experiences. Alexithymia is observed among individuals with a variety of mental health problems (Taylor, 2000; Taylor, Bagby, & Parker, 1997), and may characterize more severe clinical presentations (e.g., Frewen, Dozois, Neufeld, & Lanius, 2008). In addition, alexithymia seems to be related to adverse treatment outcomes (Kosten, Krystal, Giller, Frank, & Dan, 1992; Ogrodniczuk, Piper, & Joyce, 2011). This study adds to the current literature by examining the effect of alexithymia and emotion regulation (i.e., emotion suppression; emotion acceptance) on variables associated with trauma memory …

Hif-2 Regulation Of Amino Acid Transporter Expression In Hepatocellular Carcinoma Cells, Jason A. Misurelli

Graduate Research Theses & Dissertations

Hypoxia represents a major driver of the cancer phenotype in solid tumors, especially those of hepatic origin. Low oxygen availability triggers a complex cellular response which alters metabolism and promotes cellular invasion. Growing evidence suggests the amino acid glutamine, an important molecular currency for both energy producing reactions and biosynthetic pathways, plays an enhanced role in cancer cells under hypoxia. Hypoxia-inducible factors (HIFs) are transcription factors crucial for regulating the cellular response to low oxygen. Family member HIF-1 has been well studied, however, recent evidence suggests HIF-2 may have a regulatory role in amino acid transport and metabolism under hypoxia. …

Unsc Legitimacy As A Tool For Misdirection, Medha Monjaury

Graduate Research Theses & Dissertations

In the months leading up to the 2003 invasion of Iraq, the Bush administration made clear to the American people that the United States was prepared to go to war if Iraq failed to comply with Resolution 1441 and disarm. However, during the process of drafting and passing Resolution 1441, the U.S. expended considerable time and energy maintaining to the United Nations Security Council that it would not use the resolution as a pretext to strike Iraq. Moreover, it appears that the Security Council was convinced of the U.S.’ stated intentions when it passed Resolution 1441 unanimously in November 2002, …

Bayesian Lasso Survival Analysis, Justin P. Neely

Graduate Research Theses & Dissertations

This thesis examines the use of Bayesian LASSO regression for survival data to estimate the survival function and to select significant covariates simultaneously. We consider survival times of patients with adenocarcinoma lung cancer. The survival and genetic data are available in the Cancer Genome Atlas (TCGA) Research Network. As a pilot study, within chromosome 5, we apply Bayesian LASSO regression to explore genetic markers that may help to identify crucial genes to determine survival times of patients. Using Gibbs sampling we can obtain Markov Chain Monte Carlo samples for regression coefficients and model variance as well as LASSO penalty from …

The Role Of Sensory And Affective Systems In The Semantic Processing Of Abstract Concepts, Jane Elizabeth Neal

Graduate Research Theses & Dissertations

The role of modal, or embodied, systems in the semantic representation of abstract concepts, which are by nature not experienced by the senses, remains unclear. The experiments presented in this dissertation investigated the extent to which the activation of visual or affective systems may be modulated by context. Experiment 1 examined whether a verbal or visual memory load interfered with the semantic processing of abstract concepts paired with either a low or highly imageable adjective, and whether processing was similarly affected for concrete concepts. While the cognitive loads were effectively maintained, neither load type affected processing times for either concept …

The Hero Never Leaves The Tavern: Complicating Narrative In Dungeons & Dragons, Christopher Nelson

Graduate Research Theses & Dissertations

This thesis aims to explore how Dungeons & Dragons complicates storytelling elements such as the role of narrator and audience and the structure of the hero’s journey. Using the Game Trailers Archive’s Tabletop Adventures series as a case study, I analyze over 50 hours of gameplay along with studying Dungeons & Dragons’s history and what influenced its creation and narrative style. This study is meant as an examination of the role of audience and narrator in Dungeons & Dragons and the game’s narrative elements using the lenses of Wayne Booth’s theories on the narrator as stated in his book The …

Why We Turn The Page: A Literary Theory Of Dynamic Structuralism, Justin J. J. Ness

Graduate Research Theses & Dissertations

This study claims that every narrative text intrinsically possesses a structure of fixed relationships among its interest components. The progress of literary structuralism gave more attention to the static nature of what a narrative is than it did to the dynamic nature of how it operates. This study seeks to build on the work of those few theorists who have addressed this general oversight and to contribute a more comprehensive framework through which literary critics may better chart the distinct tensions that a narrative text cultivates as it proactively produces interest to motivate a reader’s continued investment therein. This study …

Ground Beetle Community Structure And Function In Restored Tallgrass Prairie, Melissa Nelson

Graduate Research Theses & Dissertations

With the removal and destruction of natural areas for human use, there is a push to restore natural habitats. However, most restoration activities focus on reestablishing plant communities, while less is known about the recovery of organisms in higher trophic levels and their functional roles. Considering functional traits (those that explain an organisms’ response to environmental change and impacts on ecosystems) of restored communities may reveal how communities, and the ecosystem functions they drive, recover. Of particular interest are ground beetles (Coleoptera: Carabidae) because of their diversity and important ecological roles as consumers. This study focused on the ground beetle …

Examining Political Discourse On A Crafting Website, Laura Steibel O'Brien

Graduate Research Theses & Dissertations

Websites dedicated to leisure pursuits are often used to connect with others over a shared interest. Some allow and encourage participants to engage in discussion. This project examined the ways that one crafting website, Ravelry, attempts to maintain civil discourse among its users, as opposed to the sometimes hostile and aggressive interactions found on other sites. The study looked at its discussion moderation practices as its users discussed politics and then analyzed how this related to community norms and practices of civil public discourse. Discourse analysis of words, phrases, and interactions within representative discussion threads suggest that while Ravelry’s guidelines …

Microbiome And Metagenome Of An Anthropogenic Hyperalkaline Slag-Fill Waterway In South Chicago, Illinois, Usa, Jan Ingemar Ohlsson

Graduate Research Theses & Dissertations

The aquifers and waterways around the Lake Calumet area of south Chicago, IL, USA have been affected by a century of intensive industrial waste dumping. Steel slag in particular was used as infilling to claim most of the Calumet Wetlands for industrial and residential development. Since the prohibition and cessation of these disposal activities, a growing body of research has recorded the environmental and health effects of the infill, particularly where interactions between slag minerals and rainwater produces extremely alkaline groundwater (pH ≥13). Atmospheric carbon dioxide interacting with these calcium hydroxide-rich slag fluids produces massive precipitation of a loose, white …

Latino Students’ Experiences With Bullying Victimization And Internalizing And Externalizing Distress Outcomes: The Role Of Family Support, Jocelyn Arlene Ortiz

Graduate Research Theses & Dissertations

Bullying victimization is relatively prevalent within schools and a significant number of White students (23%) and Latino students (16%) have reported being bullied at school. Research on bullying victimization has found that students who experience bullying victimization are more likely to experience negative internalizing, externalizing, and academic outcomes. Research on familismo (i.e., an individual’s strong identification with and attachment to their family that involves feelings of loyalty, reciprocity, and solidarity to the family) suggests that this cultural value may play a bigger role within the outcomes of Latinos because of its importance within Latino culture. The current study examined whether …

A Computational Fluid Dynamics Analysis Of The Aerodynamic Performance Of Wind Turbine, Ashkan Ostovari

Graduate Research Theses & Dissertations

Renewable energy resources are likely to be a future energy solution. Among them, the wind has gained a lot of interest. Despite the theoretical limitation in wind energy harnessing efficiency, it is, still, one of the most promising renewable resources with utilizing turbines to extract this energy. Wind turbines, based on their axis of rotation are categorized into vertical axis wind turbine (VAWT) and horizontal axis wind turbine (HAWT), which HAWT’s have shown relatively higher efficiency than VAWT’s. The aim of this thesis is first to develop a scaled-down model of a wind turbine in Computational Fluid Dynamics (CFD) environment …

International Institutions And Inertia: Unsc Behavior On Myanmar’S Internal Ethnic Conflicts, Matthew Peerboom

Graduate Research Theses & Dissertations

Since the resurgence of Rakhine State's conflict in 2017, and the resulting 750,000 refugees, Myanmar has received increased scrutiny by the United Nations Security Council (UNSC). However, some of Myanmar's ethnic conflicts have been continuous since independence in 1948, and thus begs the question: what explains the difference in attention? Three analytical lenses will be utilized to examine UNSC behavior: Bureaucratic Institutionalism, Geopolitics, and the null hypothesis of sheer Magnitude. In the end, it appears Institutionalism has come out as the strongest driver of Council action escalation on Myanmar. For Kayin’s low action period, it met two of the conditions …

The Evolution Of Educational Rights Of School Officials And Parents Of Disabled Students: A Review Of Related Litigation, Laura C. Pawlak

Graduate Research Theses & Dissertations

This study attempts to examine the evolution of the rights of parents of students with disabilities. For more than 40 years since President Gerald Ford signed Public Law 94-142, The Education for All Handicapped Children Act, into law, the ability for parents to advocate for their child with a disability continues to evolve. At the same time, school officials continue to care for all students in loco parentis, advocating to have the educational needs of children met.

Often, when parents and school officials meet around the table to plan an Individualized Education Plan (IEP) for a student with a disability, …

Cognitive Bias Modification For Negative Sexual Assault Disclosure Experiences: Examining A Mechanism For Improving Post-Disclosure Well-Being, Caitlin Mary Mcnamara Pinciotti

Graduate Research Theses & Dissertations

Following a sexual assault, many survivors choose to disclose the experience to others. More commonly, these conversations occur between friends, family members, or significant others, but survivors may also disclose to professionals, such as law enforcement and medical professionals. Unfortunately, support providers often do not respond supportively to disclosing survivors, and unsupportive acknowledgement and turning-against reactions are common. Extant literature has overwhelmingly indicated that these negative reactions have lasting detrimental effects on survivors, including leading to increased symptoms of posttraumatic stress disorder (PTSD) and other adverse outcomes. Although social support and PTSD theories converge to suggest that negative disclosure experiences …

Exceptionalism And Transatlanticism In Early American Literature (1760-1860) And Classic Hollywood Cinema (1930-1960), John M. Price

Graduate Research Theses & Dissertations

This dissertation explores the seemingly contradictory characteristics of two distinct art forms in two distinct eras. When exploring the period 1760 to 1860, scholars of transatlanticism argue that the literature of Great Britain and the young United States are of one unified cultural identity, and yet this period is also one in which American writers sought to establish a unique national voice. To understand this dichotomy, this dissertation examines the parallels between Early American Literature, or EAL, and classic Hollywood cinema (1930-1960). This exercise in intertextuality demonstrates how both mediums in both periods absorbed influences from other countries and other …

Computational Methods For Bicubic L1 Splines, Priyesh Koyu Rai

Graduate Research Theses & Dissertations

The past two decades have seen the development of L1 splines for interpolation and approximation of geometric data. L1 splines have been shown to preserve shapes better than the conventional L2 splines, especially for data with abrupt changes in the magnitude of spacing. Efficient computation plays an important role in the practical application of L1 splines. This thesis creates new computational methods for constructing bicubic L1 interpolating splines and bicubic L1 spline fits. The bicubic splines in this study are piecewise bicubic polynomials defined on a rectangular grid generated by the tensor product of nodes. We developed a hybrid computational …

Seabird Threats On Land And At Sea: Measuring Nearshore Response To Invasive Predator Eradications And Storm Petrel Diet Response To Fishing Expansion, Lyndsay L. Rankin

Graduate Research Theses & Dissertations

Seabirds are crucial components of many marine and island ecosystems, and yet they are the world’s most threatened group of birds. They spend most of their lives at sea, where they face numerous threats including climate change, pollution, and fisheries. When they return to land to breed, they are threatened by human disturbance and invasive species. This research examines seabird response to threats on land and at sea using stable isotope analysis. Seabirds provide multiple ecosystem services, such as depositing rich marine-derived nutrients into the islands where they nest. Invasive predators disrupt this bottom-up control by decimating seabird populations. Successful …

Exploring The Relationship Between Facets Of Mindfulness And Emotion Regulatory Flexibility, Anthony Nicholas Reffi

Graduate Research Theses & Dissertations

Emotion dysregulation can often be attributed to an inability to employ a range of regulatory strategies across varying stressful situations (i.e., regulatory flexibility). Therefore, it remains clinically relevant to determine the mechanisms that facilitate regulatory flexibility. Although mindfulness and regulatory flexibility have been linked, relations between mindfulness facets and regulatory flexibility have not yet been considered. This study aimed to determine which facets of self-reported trait mindfulness are related to regulatory choice flexibility. Using a previously validated performance-based emotion regulation choice paradigm, undergraduates (N = 78; 62.8% female; Mage = 19.82, SD = 2.03) chose to use either reappraisal or …

Barrier Graphs And Extremal Questions On Line, Ray, Segment, And Hyperplane Sensor Networks, Kirk Anthony Boyer

Electronic Theses and Dissertations

A sensor network is typically modeled as a collection of spatially distributed objects with the same shape, generally for the purpose of surveilling or protecting areas and locations. In this dissertation we address several questions relating to sensors with linear shapes: line, line segment, and rays in the plane, and hyperplanes in higher dimensions.

First we explore ray sensor networks in the plane, whose resilience is the number of sensors that must be crossed by an agent traveling between two known locations. The coverage of such a network is described by a particular tripartite graph, the barrier graph of the …

A Multimethod Investigation Of Emotional Labor And Sleep Quality: Can Perceptions Of Sleep Quality Influence Health And Emotion Regulation?, Arielle P. Rogers

Graduate Research Theses & Dissertations

Sleep and emotional labor (i.e., emotion regulation at work) are integral to health and job performance. Poor sleep quality has been linked to decreased emotional labor; however, no study has examined the reason for this relationship. This study draws from models of self-regulation to suggest that perceptions of good sleep quality can increase employees’ motivation to exert emotional labor in the absence of display rules (i.e., “display autonomy”), resulting in better emotion performance (i.e., coded affective displays) and health (i.e., decreased emotional exhaustion). College students (N = 205) were randomly assigned to a “display rules” or “display autonomy” condition and …

A Child Shall Lead Them: Exploring Discourses Of Efficacy And Climate Change As They Appear In Children's Animated Film, Jason Derry

Electronic Theses and Dissertations

Recent climate change discourse has tended to presume scientific knowledge and rational argumentation as the principle factor in convincing peoples and publics toward climate action. However, scholarship across numerous fields reveals myriad other contributing factors in how people think about and respond to this environmental crisis, which leans predominately toward silence and apathy. Alongside this, children are often centered as inheriting a calamity, yet find themselves largely disempowered. From out of this rhetorical milieu I interject by way of a multidisciplinary grounding to examine the predominate framings of efficacy in the context of children, climate change, and environmental discourse. To …
