Dyadic And Ecological Associations With Intimate Partner Violence (Ipv): Using Hierarchical Linear Modeling To Differentiate Ipv From Community Crime, Rachel Carpenter

Electronic Theses and Dissertations

Research on intimate partner violence (IPV) and intimate partner sexual violence (IPSV) has largely focused on individual and dyadic-level risk factors, but recently studies have explored how the surrounding environment is associated with IPV/IPSV. Studies that have explored community-level variables typically only use IPV/IPSV samples and do not first compare indicators of IPV/IPSV to those of general crime in those same communities. To address these gaps, this study was conducted in two parts. Data were retrieved from the Tennessee Bureau of Investigation Reporting System, County Health Rankings and Roadmaps System, the US Census Bureau, and other sources. Study 1 first …

Assessing The Applicability Of A Three-Minute All-Out Swimming Test In Collegiate Swimmers, Luis Rodriguez-Castellano

Electronic Theses and Dissertations

Performance tests are used to gauge swimmer fitness and guide training prescription. While some traditional protocols, such as, best average swimming (Bavg) lack scientific support, the three-minute all-out test (3MT) is validated to measure critical speed (CS) and distance capacity above CS (D’) from a single maximal swimming bout. In collegiate swimming, a 3MT could be convenient and time efficient. Yet, issues arise with calculating 3MT parameters. Moreover, anthropometry, resistance training, and stroke technique may influence swimming performance and physiological thresholds including 3MT parameters. Hence, this dissertation focused on evaluating the 3MT parameter calculation methods using the interval and lap …

Enestr¨Om-Kakeya Type Results For Complex And Quaternionic Polynomials, Matthew Gladin

Electronic Theses and Dissertations

The well known Eneström-Kakeya Theorem states that: for P(z)=∑_i=0ⁿ a_i zⁱ, a polynomial of degree n with real coefficients satisfying 0 ≤ a₀ ≤ a₁ ≤ ⋯≤ a_n, all zeros of P(z) lie in |z|≤1 in the complex plane. In this thesis, we will find inner and outer bounds in which the zeros of complex and quaternionic polynomials lie. We will do this by imposing restrictions on the real and imaginary parts, and on the moduli, of the complex and quaternionic coefficients. We also apply similar restrictions on complex polynomials with …

Youth-Friendly, Person-Centered Contraceptive Care For Adolescents: Exploring The Capacity Of Safety-Net Clinics In Alabama And South Carolina, Kristen Surles

Electronic Theses and Dissertations

Introduction: In recent years, high quality contraceptive care for adolescents has shifted away from tiered effectiveness counseling and toward youth-friendly, patient-centered counseling (YFPCCC). YFPCCC is essential in the South, which has higher rates of sexual activity, lower rates of contraception use, and higher teen birth rates. This study examined Southern clinics’ characteristics which support YFPCCC and youth’s perceptions of the contraceptive care they receive.

Methods: This mixed methods study examined secondary data collected in two surveys and primary data collected through key-informant interviews. The first survey examined clinic characteristics impacting YFPCCC, and the second survey examined adolescents’ (aged 16-24) perspectives …

Japanese Canadians In World War Ii: Neglected Historiography, Clayton Huff

Electronic Theses and Dissertations

During World War II, Japanese across North America were forced into internment camps out of suspicion and wartime hysteria. The historiography has chosen to focus specifically on Japanese Americans and their experiences. Academic and popular history is overwhelmingly focused on Japanese Americans, with minimal discussion ever given to Japanese Canadians or Mexicans who were interned. Tens of thousands of Japanese Canadians were interned during this tumultuous time. By ignoring their testimonies and hardships, history has forgotten these oppressed people. This thesis seeks to examine the current historiography of Japanese Canadians and compare it to that of Japanese Americans while also …

Cultural Lag Does Not Exist: An Exposition And Critical Evaluation Of W.F. Ogburn’S Hypothesis, Heather L. Osborne

Electronic Theses and Dissertations

Despite a century of scholarly critique, William Fielding Ogburn’s cultural lag hypothesis (CLH) endures. The inclusion of Ogburn’s hypothesis in introductory sociology textbooks, reference books, and histories of technology lends an unwarranted authority to its scientific credibility. I critically assess Ogburn’s CLH and find that it is neither scientifically nor theoretically sound. Specifically, I discover presumptions of cultural integration and normative progressivism, the fallacy of ambiguity, problems of causal explanation, operationalization, and selective bias, which renders the CLH unmeasurable, unfalsifiable, and non-replicable. Finally, I briefly discuss the implications and make suggestions for future research.

Student Relational Maintenance With Instructors: Scale Development And Validation, Emily N. Napier

Electronic Theses and Dissertations

This thesis examined the instructor-student relationship through an interpersonal communication perspective. The current thesis took a two-step process to first derive participant-generated responses concerning undergraduate student maintenance behaviors and second to construct and validate a scale concerning those behaviors. Of additional interest was to explore reasons as to why students aim to maintain these relationships. A 16-item measure titled the Student Relational Maintenance Scale was created and consists of making connections, advice seeking, etiquette, and attendance behaviors. Additionally, results revealed that both professional and personal reasons motivated students to build these relationships. Making connections, advice seeking, etiquette, and attendance behaviors …

Three broad categories of experience were found: RAs who were considered essential employees and required to work during the pandemic, RAs who were given the option of working during the pandemic, and RAs who were laid off at the beginning of their pandemic. The central research question was regarding the perceived experience of RAs …

The Stringent Response In Pseudomonas Aeruginosa Influences The Phenotypes Controlled By The Gac/Rsm System, Michael Shawn Hooker

Electronic Theses and Dissertations

Pseudomonas aeruginosa is a ubiquitous, opportunistic pathogen that causes acute and chronic infections. Infection is typically initiated via motile and virulent strains. After exposure to stressors, acute infections make both genotypic and phenotypic switches to a chronic, sessile strain. This is due to intricate regulatory networks directing gene expression in response to stressors. One network, GacA/GacS, has been established to control virulence factors. The stringent response of bacteria is mediated by alarmones produced primarily by RelA which responds to starvation.

To study the effect of the stringent response on the virulence switch. A series of experiments were run in both …

Unsupervised Dimension Reduction Techniques For Lung Diagnosis Using Radiomics, Janet Kireta

Electronic Theses and Dissertations

Over the years, cancer has increasingly become a global health problem [12]. For successful treatment, early detection and diagnosis is critical. Radiomics is the use of CT, PET, MRI or Ultrasound imaging as input data, extracting features from image-based data, and then using machine learning for quantitative analysis and disease prediction [23, 14, 19, 1]. Feature reduction is critical as most quantitative features can have unnecessary redundant characteristics. The objective of this research is to use machine learning techniques in reducing the number of dimensions, thereby rendering the data manageable. Radiomics steps include Imaging, segmentation, feature extraction, and analysis. For …

“It’S Alive!” The Birth And Afterlife Of The Gothic Genre, Tanner Linkous

Electronic Theses and Dissertations

This thesis explores the development of the Gothic novel in England throughout the eighteenth and nineteenth centuries. This thesis establishes the Gothic as a literary mode of middle-class terror by analyzing Gothic novels within the historical context of the Industrial and Democratic revolutions. This requires an in-depth understanding of politics throughout both centuries and this thesis engages with several sources such as Maggie Kilgour’s The Rise of the Gothic Novel which adds important context to my claims. Additionally, I use several contemporary sources such as Godwin’s Caleb Williams, the writings of Edmund Burke, and On the Pleasure Derived from Objects …

The abundance, accessibility, and scale of data have engendered an era where machine learning can quickly and accurately solve complex problems, identify complicated patterns, and uncover intricate trends. One research area where many have applied these techniques is the stock market. Yet, financial domains are influenced by many factors and are notoriously difficult to predict due to their volatile and multivariate behavior. However, the literature indicates that public sentiment data may exhibit significant predictive qualities and improve a model’s ability to predict intricate trends. In this study, momentum SVM classification accuracy was compared between datasets that did and did not …

Identifying Taphonomic Distribution Patterns At The Gray Fossil Site, Shawn Haugrud

Electronic Theses and Dissertations

Since the early days of the discovery of the Gray Fossil Site (GFS), meticulous efforts to preserve the spatial data were a priority. Direct surveying of fossils prior to recovery, as well as grid mapping the site, provided relative spatial data within a square meter. Such efforts meant that even fragments and microfossils, recovered during the screening operations and eventual concentrate picking, maintained some spatial data. Available spatial data are used to identify smaller deposits within the greater system, as well as non-random distribution patterns among a number of GFS taxa. Patterns are particularly pronounced in the large-bodied taxa, Teleoceras …

Consuming The World: Poetic Appetite, Memory, And Identity In Li-Young Lee’S Food Poems, Claire Liszka

Electronic Theses and Dissertations

Food is a universal human necessity, yet food often serves more than a biological purpose as it informs individual and communal identities, and even facilitates memory. This thesis explores personal memory, the development of identity, and an almost reverential connection to nature in several food poems by Li-Young Lee in Rose (1986) and Behind My Eyes (2008). Born in 1957, Lee has been writing poetry since he was young, studying under Gerald Stern in the late 1970s, and he is known for writing sublime, transcendent yet incredibly accessible and expressive poetry.

Spin Trapping Behavior Of Some Selected Melatonin Derivatives For Hydroxyl Radicals: A Computational Study, Aaron Caesar

Electronic Theses and Dissertations

Melatonin (N-acetyl-5-methoxytryptamin, MLT) is a naturally occurring antioxidant which has shown some potential for use as a spin trap. Spin traps react with short lived hydroxyl radicals (HO·) to produce more stable products called spin adducts which may be characterized by electron paramagnetic resonance spectroscopy. However, the relative stability of hydroxyl spin adducts of melatonin derivatives (MLTD) compared to 2-hydroxymelatonin (HO-MLT) has not been examined computationally. Computational studies have been done on four selected MLTD; methylmelatonin (Me-MLT), chloromelatonin (Cl-MLT), cyanomelatonin (CN-MLT), and nitromelatonin (NO₂-MLT). Geometry of the structures were optimized at the HF/6-31G(d), cc-pVXZ, (X=D and T) and …

Brand-Funded Documentary Films And Climate Change: An Aristotelian Rhetorical Analysis, Matthew Rossetti

Electronic Theses and Dissertations

This paper examines the concept of brand-funded documentaries that center on the issue of climate change and uses Aristotle’s Rhetorical Triangle to better understand how the films use rhetoric in communicating their message. A rhetorical analysis was conducted using four brand films from Amazon, Corona, Patagonia and REI and the results are intended to demonstrate the best methods of persuasion and the most effective rhetoric utilized in brand-funded documentaries. Because brand-funded documentaries not only make an argument about a particular issue, in this case climate change, but also must communicate a particular brand’s values and commitments, examining the rhetoric in …
