Beaver Creek is an impaired streams that is not supporting its designated use for recreation due to Escherichia coli (E.coli), and sediment. To address this problem, this thesis was divided into two studies.

The first study explored changes in Land Use Land Cover (LULC), and its impact on surface water quality. Changes in E.coli load between 1997-2001 and 2014-2018 were analyzed. Also, Landsat data of 2001, and 2018 were examined in Terrset 18.31. Mann-Whitney test only showed a significant reduction in E.coli for one site. Negative correlation was established between E.coli load, and Developed LULC, Forest LULC, and …

"Wand'ring This Woody Maze": Deciphering The Obscure Wilderness Of Paradise Regained, Brooke Johnson

Electronic Theses and Dissertations

The setting of Milton’s great sequel is puzzling, being called a desert and a “waste wild” (IV. 523) repeatedly and at the same time including descriptions of protective oaks and woody mazes. These conflicting descriptions conjure up several questions: In which environment does the epic take place? Because Milton is so detailed in his adaptations of biblical narrative the inclusion of trees is quite perplexing. While he does tend to expand biblical narrative quite frequently – e.g. Paradise Lost – he rarely initiates a change without just cause. The crux of this particular change centers on what this just cause …

A Replication And Extension Of A Prediction Tool Identifying Need For Treatment Among Opioid Exposed Infants, Loni Parrish

Electronic Theses and Dissertations

The incidences of maternal opioid use and neonatal opioid withdrawal syndrome (NOWS) have increased by nearly 400% over the past decade. Isemann and colleagues (2017) developed prediction tools (TiTE/TiTE²) to differentiate, within the first two days of life, between infants who will require pharmacotherapy for NOWS from those infants who will not require pharmacotherapy for NOWS. The goal of the current experiment was to replicate and extend their prediction model. The present experiments successfully replicated Isemann et al., (2017) results and also established alternative cutoff values for requiring treatment that provide better balance between all four metrics. Moreover, …

Ontogenetic And Adult Shape Variation In The Endocast Of Tapirus: Implications For T. Polkensis From The Gray Fossil Site, Thomas M. Gaetano

Electronic Theses and Dissertations

Endocranial morphology provides evidence of sensory ecology and sociality of extinct vertebrates. The Earliest Pliocene Gray Fossil Site (GFS) of NE Tennessee features a conspicuous dominance of skeletal elements belonging to the dwarf tapir, Tapirus polkensis. Numerous individuals in one fossil locality often suggests gregarious behavior, but sociality in T. polkensis contradicts behavior documented for extant Tapirus species. I test T. polkensis for variation in sensory and social ecology using computed tomography and 3D digital endocasts from an ontogenetic sequence. I compare the T. polkensis endocasts with extant Tapirus species using Encephalization Quotients (EQs) and 3D geometric morphometrics. Results …

Blend It Like Beckett: Samuel Beckett And Experimental Contemporary Creative Writing, Sam Nicole Campbell

Electronic Theses and Dissertations

Samuel Beckett penned novels, short stories, poetry, stage plays, radio plays, and scripts—and he did each in a way that blended genre, challenged the norms of creative writing, and surprised audiences around the globe. His experimental approach to creative writing included the use of absurdism, genre-hybridization, and ergodicism, which led to Beckett fundamentally changing the approach to creative writing. His aesthetics have trickled down through the years and can be seen in contemporary works, including Aimee Bender’s short story collection The Girl in the Flammable Skirt and Mark Z. Danielewski’s novel House of Leaves[1]. By examining these works …

Stacking The Odds For Better Gpr: An Antenna Comparison, Montana Kruske

Electronic Theses and Dissertations

Ground penetrating radar (GPR) is limited by depth penetration and signal-to-noise ratio (SNR), impacting the ability to resolve subsurface features. Stacking, a process of averaging multiple scans in the same location, improves SNR. Digital antennas are capable of stacking at much higher rates than analog antennas. Four sites were examined using a GSSI SIR-4000 GPR unit with a 400 MHz analog antenna and a 350 MHz digital “hyperstacking” (350 HS) antenna. Sites represent various soil conditions, with known features. Data were compared qualitatively and quantitatively for differences in antenna outputs. Visual inspection of radargrams indicate a reduction in noise in …

The Relationship Between Adverse Childhood Experiences, Acute Stress, And Working Memory, Marissa R. Jones

Electronic Theses and Dissertations

Working memory (WM) is a crucial component of cognitive function that affects learning, reasoning, and problem solving, all of which are important for daily functioning. Therefore, addressing factors that can impact working memory, such as stress, are incredibly relevant to understanding WM efficiency. WM is an important component of higher order cognitive function and high WM capacity has been shown to be important for academic and occupational performance. Thus, understanding the relationship between stress-related factors and WM could aid in identifying strategies to mitigate the deleterious effects of stress on working memory. Although some previous research has indicated a negative …

Climate Variability From 1980 To 2018 And Its Effect On Wind Directions, Wind Speeds, And Vog Dispersal In Hawaii, Monica Ayala

Electronic Theses and Dissertations

Wind patterns in the Pacific Ocean fluctuate seasonally, annually, and decadally, resulting in changes in the dispersal of volcanic smog (vog) across the Hawaiian Islands. A variety of synoptic-scale weather patterns can affect the Islands, creating variability in the direction and intensity of wind patterns. Recent changes in wind profiles were analyzed to identify possible patterns that could influence and increase the dispersion of vog over time on Hawai’i Island and the other Hawaiian Islands to the northwest. Historically, Northeast Trade Winds prevailed for much of the year, shifting vog into the Pacific Ocean southwest of Hawaii and away from …

The Powerful Presence Of Dams In Appalachian Poetry, Zoe Hester

Electronic Theses and Dissertations

Contemporary Appalachian poetry offers a lens through which we can see the immense impact that the Tennessee Valley Authority has had in Appalachia. In this thesis, I explore the powerful presence of dams in Appalachian poetry by analyzing three poems. Jesse Graves’s “The Road into the Lake” centers on personal and familial loss, Jackson Wheeler’s “The TVA Built a Dam” mourns the loss of communities, and Rose McLarney’s “Imminent Domain” focuses on the ecological destruction that has occurred in Appalachia and around the globe as the result of the construction of TVA dams. Ultimately, all three poems serve as eulogies …

Evaluation Of A Jail Reentry Program., Bailey Elisabeth Holland

Electronic Theses and Dissertations

Previous research has focused on prison reentry programs and the impact the program has on reducing rates of recidivism, but there is a lack of research on jail reentry programs and the impact of programs’ individual services have on recidivism. Secondary data was obtained from the Louisville Metro Jail Familiar Faces Action and Community Transition (F2ACT) reentry program, which included basic demographic data of the participants, a record of individual services received by each participant, and the number of times each participant was booked into Louisville Metro Corrections before and after participating in F2ACT. A multinomial logistic regression found that …

This thesis presents a practitioner’s view on interest groups and interest group theory based primarily on Mancur Olson’s conclusions that small, organized minority interests have an advantage over the large, disorganized majority interests in the policymaking process; it tests the “why” behind this theory through an examination of a variety of factors, including the influence of money, the power of communications tools deployed by these interests, and the lobbyists’ role. It includes an introduction plus four chapters, including literature review, research methods, participant observations and in-depth interviews, and conclusion. The research methods included primarily participant observation based on a two-decade …

An Investigation Of Anxiety- And Depression-Like Behavior After Head Trauma In Mice, Sean K. Payne

Electronic Theses and Dissertations

Every year around 2 million people in the United States (US) suffer a traumatic brain injury. Those people are often at a higher risk of post-TBI psychiatric illness, like anxiety and depression. Animal models of TBI are a useful way to measure such psychiatric illnesses in a pre-clinical setting. There were two purposes of this study: the first being to test the modified Marmarou TBI model, and second to investigate anxiety- and depression-like symptoms in C57Bl6/J mice following a TBI. The modified Marmarou model used different weights (95g, 30g, & sham) to see how severity affected the manifestation of anxiety-like …

A Causal Comparative Analysis Of The Academic Self-Efficacy Of Black Male High School Students Taught By A Black Or White Male Teacher., Joseph Jones Jr.

Electronic Theses and Dissertations

The airm of this study was to determine if there was a difference in the academic-self efficacy among Black male students taught by a Black Male teacher compared to the academic self-efficacy of Black male students that are taught by a Whilte male teacher. Academically, Black male students lag behind their peers in academic achievement indicators such as grade point average, standardized test scores, and high school graduation rates (Schottt Report, 2015). Existing literature regarding Black male academic achievement focuses on exploring the academic achievement gap that exists, but little to no research investigates how to close that gap. Using …

“A Lot Of Prayer, And Some Wine In-Between”: Applying The Relational Turbulence Model To The Stepparent-Biological Parent Marriage., Paul Taylor

Electronic Theses and Dissertations

The present study utilizes the relational turbulence model (RTM) to illuminate stepparent experiences of relational uncertainty and partner interference within the context of the stepparent-biological parent marriage. In-depth, semi-structured interviews with 6 stepparents revealed four primary themes pertaining to how stepparents experienced relational uncertainty: (a) enactment of parenting, (b) competing expectations, (c) shifts in attitude and behavior by spouse, and (d) differences between marriage partners. Interference from partners was experienced by stepparents in relation to the enactment of parenting and the maintaining of the marriage as an intimate relationship.

An Unusual Mastodon Revisited: Providing A Regional Focus For Mammut Americanum (Proboscidea, Mammutidae) In The Southeast, Matthew Inabinett

Electronic Theses and Dissertations

A century ago, two large American mastodon Mammut americanum specimens from coastal South Carolina were mounted for display at Amherst College. Their robust build, broad and pentalophodont third molars, and well-developed mandibular tusks were noted as unusual. Here, these specimens are redescribed; three additional mastodon mandibles from the same region of South Carolina are also described. Though collection information on these specimens is sparse, they appear to span >150 ka in the Middle to Late Pleistocene, and probably include the first report of Mammut from the earliest-Rancholabrean Ten Mile Hill Formation. Some “unusual” features — moderately to extremely broad third …

A Poetic Ethnodrama: Discussing The Impact Of The Pressure To Publish On Creative Writers' Production, Abby N. Lewis

Electronic Theses and Dissertations

This study examines the presence of the pressure to publish while in college as an undergraduate or graduate student, and the impact that pressure has on students’ ability to produce creative work. After interviewing participants, the researcher created an ethnodrama to best represent participants’ emotions and unique experiences with publishing while in school. An examination of the literature reveals that master’s-level students are often overlooked in scholarly research on the subject of publishing. This study uses a qualitative research method to identify key emotional experiences from students at the master’s and undergraduate level in the hopes of providing a platform …

Tobacco Enhances Bacterial-Induced Periodontal Bone Loss In Mice., Mina Iskander

Electronic Theses and Dissertations

Background: Tobacco smoking is the leading environmental risk factor for periodontal diseases. Delineation of the mechanisms underlying tobacco-induced or exacerbated periodontitis is hampered by the lack of an appropriate and reliable animal model. Hypothesis: We hypothesized that Porphyromonas-gingivalis-infected, cigarette smoke-exposed mice would represent reproducible models of acute (ligature model) and chronic (oral gavage model) tobacco-enhanced periodontitis that reflect multiple aspects of the disease noted in human smokers. Methods: In a chronic oral gavage disease model, Balb/c mice (6-8 weeks, 4 groups of n = 6 per group) were exposed to smoke produced by a Teague-10 smoking machine from 1R6F research …

A Protocol Driven Stroke Code's Impact On Door-To-Needle Times, Jesse Osborne

Electronic Theses and Dissertations

Tissue plasminogen activator (tPA) is most effective the faster it is able to be administered to a patient that has been affected by stroke. A Stroke Code is a strategy that acute care facilities implement to reduce the time from diagnosing a stroke to administering tPA. The purpose of this study was to determine if the initiation of a Stroke Code in an acute care hospital reduces the door-to-needle time for patients affected by a stroke. In particular, does a Stroke Code reduce door-to-needle times. The research was conducted using data from April 1, 2014 to December 31, 2014 (pre-Stroke …

Managing Stress In A Constantly-Changing Workforce, Lorri Burch-Hubbard

Electronic Theses and Dissertations

When staffing reductions occur in the workplace, staff left behind may face increased stress, may not be given the support they need to manage the feelings caused by the reduction. This study was conducted to evaluate the impact of stress caused by staffing reductions has on medical technologists (MT), medical technicians (MLT) and respiratory therapists (RT), and to identify any common methods of stress management used by those staff who remain in the organization.

Literature research showed the negative impact stress can have on individuals when it is not addressed, such as decreased work performance, health issues, and even the …

Knot Flow Classification And Its Applications In Vehicular Ad-Hoc Networks (Vanet), David Schmidt

Electronic Theses and Dissertations

Intrusion detection systems (IDSs) play a crucial role in the identification and mitigation for attacks on host systems. Of these systems, vehicular ad hoc networks (VANETs) are difficult to protect due to the dynamic nature of their clients and their necessity for constant interaction with their respective cyber-physical systems. Currently, there is a need for a VANET-specific IDS that meets this criterion. To this end, a spline-based intrusion detection system has been pioneered as a solution. By combining clustering with spline-based general linear model classification, this knot flow classification method (KFC) allows for robust intrusion detection to occur. Due its …

Glare Reduction By Dark Facial Markings And Bills In Birds, Clara Lebow

Electronic Theses and Dissertations

Avian facial plumage, bill coloration, and feather microstructure may serve one or more adaptive functions. Several researchers have proposed that dark eyestripes, bills, and facial masks aid in reducing glare, however, there have been relatively few tests of this hypothesis. Dark facial markings have been shown to have an adaptive glare-reduction function in recent field studies of a few species, but this hypothesis has never been tested in a broad multispecies analysis. It is likely that feather microstructure influences feather brightness and has an effect on the efficacy of glare reduction properties of feathers. I examined the link between dark …

Effects Of Pre-Workout Caffeine Supplementation On Post-Exercise Hypotension, Shelby L. Gibbs

Electronic Theses and Dissertations

Post-exercise hypotension (PEH) is believed to play a major role in the antihypertensive health benefits of exercise. While it has been shown that resistance exercise is effective at eliciting PEH, commonly consumed sports supplements may attenuate or completely eliminate that response. Caffeine, a popular stimulant, is often consumed prior to exercise. Therefore, the purpose of this study was to investigate the effects of pre-workout caffeine supplementation on the post-exercise hypotensive response in adults with above normal blood pressure. Participants (n = 5) were recreationally resistance trained men and women who consumed placebo or caffeine (3 mg/kg bodyweight) 45-minutes prior to …

Applications Of Digital Remote Sensing To Quantify Glacier Change In Glacier And Mount Rainier National Parks, Brianna Clark

Electronic Theses and Dissertations

Digital remote sensing and geographic information systems were employed in performing area and volume calculations on glacial landscapes. Characteristics of glaciers from two geographic regions, the Intermountain Region (between the Rocky Mountain and Cascade Ranges) and the Pacific Northwest, were estimated for the years 1985, 2000, and 2015. Glacier National Park was studied for the Intermountain Region whereas Mount Rainier National Park was representative of the glaciers in the Pacific Northwest. Within the thirty year period of the study, the glaciers in Glacier National Park decreased in area by 27.5 percent while those on Mount Rainier only decreased by 5.7 …

Using Saddlepoint Approximations And Likelihood-Based Methods To Conduct Statistical Inference For The Mean Of The Beta Distribution, Bryn Brakefield

Electronic Theses and Dissertations

The prevalence of conducting statistical inference for the mean of the beta distribution has been rising in various fields of academic research, such as in immunology that analyzes proportions of rare cell population subsets. For our purposes, we will address this statistical inference problem by using likelihood-based applications to hypothesis testing, along with a relatively new statistical method called saddlepoint approximations. Through simulation work, we will compare the performance of these statistical procedures and provide both the statistical and scientific communities with recommendations on best practices.

Dixieland Crusaders: Mass Media, The Ku Klux Klan, And The Optics Of Populism, 1970-1979., Olivia E. Raymond

Electronic Theses and Dissertations

The 1970s in the United States of America ushered in transformative policies that reshaped the nation. In her landmark essay, “The Long Civil Rights Movement and the Political Uses of the Past” (2005), Dr. Jacquelyn Dowd Hall reveals how Black activists inspired “a long movement of movements.” However, often forgotten in narratives of new activism from this era is the resurgence of white reactionary social movements. This thesis argues that mass media is central to mainstreaming radical far-right ideology to a national audience. It explores the political ramifications of sensationalist coverage of the Ku Klux Klan in mass media, specifically …

Determining The Efficacy Of Additive Manufacturing For The Aerospace Spare Parts Supply Chain, Kyle O'Brien

Electronic Theses and Dissertations

This thesis investigates how additive manufacturing (AM) based on-demand part production can supplement or replace the traditional production and inventory in typical aerospace’s spare parts supply chain systems. This study focuses on the operational characteristics of AM and its impacts on the overall logistics of plant-level operations. To capture the microscopic operational aspects of the AM production, a discrete-event simulation based approach was adopted, with key AM operation resources (e.g. AM system, operator) and attributes (e.g. AM manufacturing speed, individual part characteristics and demands) accounted for in the modeling process. In addition, a benchmark warehouse inventory model was also established …

Susceptibility Assessment Of Bank And Floodplain Erosion In Stream Restoration Using A Two-Dimensional Hydrodynamic., Fereshteh Noorbakhsh

Electronic Theses and Dissertations

In the design of stream restorations, boundary shear stress (shear stress) and velocity during high flow events are the key parameters in the assessment of the risk of morphological failure associated with channel bank and bed erosion and sediment transport. The use of two-dimensional hydrodynamic models (2D Models) is becoming more common to estimate critical shear stress and velocity for stream restoration projects. These models can give detailed distribution of shear stress and velocity over floodplain surfaces and channel. Obtaining reliable and correct estimates of stress and velocity require an accurate digital terrain model, estimates of input flows at the …
