Moral Objections To Pornography: Does The Reason For Opposition Affect Consumption?, Grant Parker

Electronic Theses and Dissertations

Recent literature has suggested a link between self-described “problematic” pornography usage or pornography addiction and moral incongruence (Grubbs et al., 2022; Guidry et al., 2019). That is, when someone is morally opposed to pornography, they feel worse about their use of it. As of yet, however, no link has been established between specific reasons for objecting to pornography and their effects on consumption. Participants were 54 adults selected randomly using Amazon’s MTurk survey distribution platform. Respondents completed demographic questions and 6 scales measuring frequency of pornography use, objections to pornography, self-perceived problematic porn use, external and internal shame, God representations, …

Building Comprehension: A Causal Comparative Study Of Factors Contributing To The Oral Reading Fluency Of First Graders, Kimberly Michelle Shaw

Electronic Theses and Dissertations

Teachers are charged with the task of reaching all students academically in hopes all students will become proficient readers by third grade. Oral reading fluency is a predictor in academic success since fluency reflects comprehension. Students often come to school unprepared in their earliest years due to a lack of opportunity and/or early literacy experiences, creating an achievement gap, a disparity in academic performance between groups of students. This study identifies the correlation between socioeconomic status, race, gender, and preschool enrollment and the oral reading fluency of first-grade readers as indicated by the Dynamic Indicators of Basic Early Literacy Skills …

Teaching Students With A Mild Intellectual Disability How To Respond To Strangers Using Computer-Based Video Instruction, Chelsey Rae Simmons

Electronic Theses and Dissertations

Computer-based video instruction (CBVI) has been effective in teaching students with disabilities various health, community, and safety skills. Research suggests that CBVI is often used in conjunction with community-based instruction (CBI). Frequently, students with severe disabilities or students who are of high school age participate in CBI and/or CBVI and its accompanying research. This study investigated the effectiveness of CBVI to teach students with a mild ID, ages 11-13, appropriate responses to lures from strangers. A single-case, multiple probe across participants design was used to examine the impact of CBVI on one dependent variable, a correct two-step response (verbal and …

Creating Unicorns: Teaching Iep Literacy And Accommodation Self-Advocacy Through Asynchronous Interactive Video Modules, Kathleen M. C. Dorr

Electronic Theses and Dissertations

Data indicate that individuals who disclose their disability status to self-advocate for accommodations at the postsecondary level may be as rare as the mythical unicorn. During the 2019–20 school year in the United States, 7.3 million public education students aged 3–21 years received some form of special education services. These students account for 14% of the nation’s public school enrollment (Irwin et al., 2021). In one study, only 20% of high school students reported having received any instruction on reading and understanding their own Individualized Education Program (IEP; Agran & Hughes, 2008). In another study, only 19% of postsecondary students …

An Evaluation Of Hospital-Based Health Technology Assessment Processes In The United States., Scott Skinner

Electronic Theses and Dissertations

This research study explored the practices of hospital-based health technology assessment (HTA) in the U.S., as experienced by healthcare technology management (HTM) professionals. HTA can play an important role in helping to evaluate health technologies at both the macro (e.g., policy) level as well as at the micro (e.g., institutional) level of the public health ecosystem (C. S. Goodman, 2004). HTA seeks to broadly evaluate the effects, properties, and other impacts of various health technologies (C. S. Goodman, 2004). Common goals of HTA are to evaluate the safety, effectiveness, and cost-benefit of health technologies. A primarily phenomenological approach was used …

An Investigation Into Structural Plasticity In Peripheral Taste Neurons Associated With Taste Cell Turnover., Zachary Whiddon

Electronic Theses and Dissertations

The continual replacement of taste cells creates interesting questions regarding how the innervating neurons are impacted during this process. Here we ask how innervation within taste buds is affected when taste cell entry is inhibited and reestablished. Inhibition of sonic hedgehog signaling (Shh) is thought to inhibit taste cell turnover. Consistently, fewer new cells were added to individual taste buds after treatment with a Shh-inhibitor compared to vehicle treatment, and taste bud volume decreased after 16 days of treatment. We next examined how taste nerve fiber extension into the gustatory epithelium is affected by preventing taste cell turnover. Ten days …

Social Ecological Resilience, Social Capital, Anomie And The Impact Of Covid-19., Kevin Pacifico Gonzaga

Electronic Theses and Dissertations

From climate change to racial tension and income inequality, many difficulties face the United States and those who live within its borders. The extreme and increasing political polarization in the United States as well as the impact of the COVID-19 pandemic have only made these challenges more difficult to address. In this complex web of adversity, the concept of resilience is important to study. Resilience may be broadly defined as the ability to “bounce back” or return to adaptive functioning after experiencing significant adversity or challenges (Smith et al., 2008). Better understanding how resilience functions and the general state of …

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.

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 …

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 …

Vibroacoustic Response Of The Tympanic Membrane To Hyoid-Borne Sound Generated During Echolocation In Bats, Chelsie Snipes

Electronic Theses and Dissertations

The hyoid apparatus in laryngeally echolocating bats forms a mechanical connection between the larynx and auditory bullae and has been hypothesized to transfer the outgoing echolocation call to the middle ear during echolocation call emission. We used µCT data to build models of the hyoid apparatus and middle ear from six species of bats and used finite element modeling (FEM) to measure the vibroacoustic response of the tympanic membrane due to hyoid-borne sound generated during echolocation. We found that hyoid-borne sound in all six species stimulated the eardrum within a range likely heard by bats. Although there were minor differences …

Mechanism And Kinetics Of Photocatalytic Partial Oxidation Of Methane On Single Site Mox Reaction Centers., Clint Evrard

Electronic Theses and Dissertations

Single-site transition-metal doped photocatalysts are a class of materials in which small transition-metal oxide clusters are embedded onto the surface of zeolites, graphene, and bulk semiconductors. Experimental findings demonstrate that VO4, CrO4, NbO4, and WO4 clusters embedded on an MCM- 41 mesoporous amorphous SiO2 are effective photocatalysts for oxidative reactions. The selective direct partial oxidation of methane (POM) to form methanol is essential for efficiently utilizing natural gas. Photocatalytic methane oxidation has advantages over traditional thermal catalysis as it can be deployed at small-scale facilities to reduce methane release into the atmosphere due to flaring potentially. Our work has aimed …

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 …

Tell The Bees That Transcendentalism Is Lost: The Search For The Lost Transcendental Space In The Bee Poetry Of Emily Dickinson And Sylvia Plath, Adyson M. Ross

Electronic Theses and Dissertations

Ralph Waldo Emerson’s bee poem, “The Humble-Bee,” expresses the nineteenth-century transcendentalist philosophy of finding wholeness and oneness in nature while Sylvia Plath’s twentieth-century bee poems function as a response to Plath’s feelings of alienation and repression, indicating that transcendental peace is lost in the postmodern era. Emerson’s poem indicates the spiritual fulfilment found through observing bees and highlights the harmony between humans and nature, but women of the nineteenth century find difficulty achieving this same level of freedom; Emily Dickinson reclaims the language of transcendentalism in her bee poetry to explore a world otherwise denied to her. The effects of …

Extracting Topography From Historic Topographic Maps Using Gis-Based Deep Learning, Briar Pierce

Electronic Theses and Dissertations

Historical topographic maps are valuable resources for studying past landscapes, but they are unsuitable for geospatial analysis. Cartographic map elements must be extracted and digitized for use in GIS. This can be accomplished by sophisticated image processing and pattern recognition techniques, and more recently, artificial intelligence. While these methods are generally effective, they require high levels of technical expertise. This study presents a straightforward method to digitally extract historical topographic map elements from within popular GIS software, using new and rapidly evolving toolsets. A convolutional neural network deep learning model was used to extract elevation contour lines from a 1940 …

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 …

Bibliotherapy: A Literary And Linguistic Analysis Of Literature, Matthew Curry

Electronic Theses and Dissertations

Bibliotherapy—the process of utilizing literature for its therapeutic properties—has been around for centuries; however, it wasn’t until a surge of research in the 1920s that the process became recognized as an adequate method of therapy. With the rising mental health crisis looming over the United States, the time to develop, establish, and advocate for a bibliotherapeutic curriculum in K-12 public education is now. Using literary works such as Gary Paulsen’s Hatchet, Helena Fox’s How it Feels to Float, and Laurie Halse Anderson’s Speak, this thesis establishes the literary, therapeutic, and pedagogical reasoning for the implementation of such …

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 …

Approaching Trans Healthcare Competency: The Implementation Of Trans Health Education For Medical Providers In Appalachia, Rebecca Altschuler

Electronic Theses and Dissertations

Barriers to competent and safe healthcare disproportionately impact people who are marginalized because of their race, ethnicity, gender, or socioeconomic status. It is well documented that transgender patients in particular experience barriers to both accessing care and receiving high quality, non-discriminatory care (Hatzenbuehler & Pachankis, 2016; James et al., 2016; Rahman et al., 2019; Safer et al., 2016). This lack of access to culturally competent healthcare services contributes to health disparities that disproportionately impact the trans community. Literature on barriers to competent care for trans patients indicates that providers experience discomfort related to their ability to provide competent care (Safer …
