To examine this phenomenon, the District of North Dakota Federal Probation and Pretrial Supervision Service records have been disseminated. Overall, the results indicate that child pornographers in North Dakota mirror those around the globe. In addition, the sample of child pornographers was compared to other sexual offenders and general offenders through bivariate analyses. There were …

The Dangers Of Power: Government Control In The Worlds Of Condie’S Matched And Lowry’S The Giver, Deborah Faith Haley

English

This paper considers the topic of government control through the context of young adult dystopian literature. The novels The Giver (1993) by Lois Lowry and Matched (2011) by Ally Condie are specifically considered in their connection to governmental control over an entire society. The novels The Giver and Matched both provide views into worlds where such basic human experiences as language use and memory are controlled, so that the protagonists—Jonas (The Giver) and Cassia (Matched) –find themselves torn between trusting what they have been told all their lives by their respective societies and what they have come to understand through …

Exploring Aspects Of Science Literacy Demonstrated By Early Undergraduate Stem Majors Through A Manuscript-Style Writing Assignment, Samantha Lynn Jusino

Graduate Theses, Dissertations, and Problem Reports (ETD)

Over the past twenty years, scientific literacy amongst undergraduates has not improved despite their exposure to higher education science classes. Underlying mechanisms of science literacy development are poorly understood; however, exposure to authentic practices in science has been demonstrated as a means to fostering science literacy development. A unique approach to studying science literacy is through examining the three domains of the science literacy conceptual framework developed in this study, Science as Access, Science as Process, and Science as a Sociopolitical Factor and their components as they emerge through the process of writing a manuscript-style writing assignment. In …

The Museum Of Queer Curiosities, Reba "Feliks" Kay Pyron

Graduate Theses, Dissertations, and Problem Reports (ETD)

This paper documents the research, personal motivations, and processes that make The Museum of Queer Curiosities (TMOQC). The installation, exhibited in the Paul Mesaros Gallery, uses the manipulation of traditional techniques in printmaking, sculpture, and craft, to create a space in which authority, labels, confusion, and compassion are discussed. Through the synthesis of familiar visual art installation techniques and museum display, the work attempts to provide a foothold for the viewer to navigate queerness and ephemeral identity. The body of work that occupies TMOQC creates the surreal simulation of a scientific museum, transforming the art gallery into a stage where …

Tobacco Cessation In A Dental School Setting, Kerri T. Simpson

Graduate Theses, Dissertations, and Problem Reports (ETD)

Introduction

Tobacco use remains the single largest preventable cause of death in the United States. Currently, the prevalence of tobacco use is 20.7% in adults (≥18 years old) and 31.2% among high school students. According to various studies, over 60% of Americans want to quit tobacco, but it takes a person several attempts to quit before they are successful. There is limited data in the literature that discusses the effectiveness of tobacco cessation programs in US dental schools. Therefore, information on the effectiveness of a tobacco cessation program in a dental school setting could benefit this state and the problem …

Leaf Angle And Leaf Stomata Responses To Experimental Drought In Quercus Velutina And Acer Saccharum, Brittany Nichole Casey

Graduate Theses, Dissertations, and Problem Reports (ETD)

The possibility of increased severity and frequency of drought conditions, as a result of global climate variability, greatly complicates our ability to forecast future forest functions such as productivity and carbon sequestration. Assessing how tree species vary in their response to drought can aid in predicting the impact on forest ecosystems as a whole. Throughfall exclusion (TfE) experiments are potentially useful tools to simulate realistic drought conditions within intact forest ecosystems. We employed a TfE experiment during the 2018 growing season within the WV Land Trust’s Elizabeth’s Woods Nature Preserve, near Morgantown, WV, to assess the leaf angle and leaf …

Predictors Of Self-Control During Emerging Adulthood: The Roles Of Implicit Beliefs And Early Risk, Katy L. Delong

Graduate Theses, Dissertations, and Problem Reports (ETD)

This study explored how early adverse experiences (i.e., low socioeconomic status, household chaos, attachment insecurity) and implicit beliefs about self-control (i.e., whether self-control is a limited or nonlimited resource) were associated with trait and momentary self-control in a sample of college students. As the first study to explore these factors together, individuals’ implicit beliefs were tested as a moderator and meditator of the association between early risk and self-control. Participants (N = 214) first completed a baseline survey with the main predictors and trait self-control, followed by one week of experience sampling to assess momentary self-control, or success resisting …

Blind Image Denoising Using Supervised And Unsupervised Learning, Surekha Pachipulusu

Graduate Theses, Dissertations, and Problem Reports (ETD)

Image denoising is an important problem in image processing and computer vision. In real-world applications, denoising is often a pre-processing step (so-called low-level vision task) before image segmentation, object detection, and recognition at higher levels. Traditional image denoising algorithms often make idealistic assumptions with the noise (e.g., additive white Gaussian or Poisson). However, the noise in the real-world images such as high-ISO photos and microscopic fluorescence images are more complex. Accordingly, the performance of those traditional approaches degrades rapidly on real-world data. Such blind image denoising has remained an open problem in the literature.

In this project, we report two …

The Morphological, Physiological, And Genetic Underpinnings Of Intraspecific Salinity Tolerance In Sorghum Bicolor, Ashley N. Henderson

Graduate Theses, Dissertations, and Problem Reports (ETD)

Decreases in land quality and quantity threaten the efficient production of agriculturally and economically pivotal crops. Such reductions in arable lands are a consequence of population growth and urbanization, and often result in the introduction of various abiotic stresses. The most common abiotic stressors include water limitation (drought), water logging (over watering), poor water quality (salinity), and extreme temperatures (cold, frost, heat). Each of these stressors negatively impact plant growth, development, and yield. Soil salinity, specifically, is a considerable constraint affecting lands used in agriculture. Salts in the soil rise both naturally and through anthropogenic factors making the abundance a …

Structural Characterization Of Emerging Synthetic Drugs, Jay Tyler Davidson

Graduate Theses, Dissertations, and Problem Reports (ETD)

The identification of well-characterized seized drugs is performed thousands of times a day in the United States; however, the expanding use of emerging synthetic drugs is creating a growing problem for both toxicological and seized drug analyses. Two of the most rapidly growing areas of emerging synthetic drugs are synthetic cathinones and fentanyl-related compounds (FRCs). In this work we demonstrate the combination of multi-stage mass spectrometry (MSⁿ), accurate mass measurements with high-resolution mass spectrometry (HRMS), and isotopic labeling for the structural characterization of synthetic cathinones and fentanyl analogs. The deliverables of this research include the identification of conserved …

Frontal Brain Injury: Effects On Flexibility, Impulse Control, And Attention, Christopher Matthew O'Hearn

Graduate Theses, Dissertations, and Problem Reports (ETD)

Traumatic Brain Injury (TBI) is defined as an impact to the head, penetration of the skull, or rapid deceleration of the skull, resulting in an alteration of brain function or neurological deficit. Cognitive deficits are common following TBI and often go unresolved due to a lack of effective treatments. These deficits often perseverate into the chronic post injury phase, so the development of rehabilitative strategies is imperative. Behavioral flexibility, impulse control, and attention are a few cognitive processes that are commonly affected by TBI. The current research compares these processes between rats with and without a severe frontal brain injury …

Ultrafast Optical Properties Of La0.7sr0.3mno3 Thin Films, Saeed Yousefi Sarraf

Graduate Theses, Dissertations, and Problem Reports (ETD)

Thin film solids often exhibit different physical properties in the ultra-thin regime. Enhancement of surface to bulk ratio results in the domination of surface/interface related phenomena such as surface recombination. Moreover, in the ultra-thin regime, quantum size and quantum confinement effects can alter the band gap of the system and constrain the strain wave propagation in the thin film. Ultrafast properties of solids can also be drastically altered in the ultra-thin regime due to the aforementioned phenomena. Experimentally, observation of these phenomena is challenging due to the insufficient material to absorb and interact with the electromagnetic wave. This dissertation addresses …

Prescribing The Profession: Representations Of Medical Professionalization Debates In American Literary Forms, 1830-1940, Jeffrey Wayne Yeager

This dissertation traces the debates concerning the professionalization of medicine in America across the 19^th- and well into the 20^th-century and explores how the debates concerning professionalization in any given moment affected popular literary forms. Using Fredric Jameson’s The Political Unconscious as its theoretical framework, this dissertation’s chapters on the gothic, realism, naturalism, and satire trace each mode’s dominant hegemonic position on this issue while showcasing dissenting voices across this century-long discourse. This project’s methodology is centered in the New Historicism. Unlike other projects before it, this dissertation focuses primarily on the historical problem of state …

Tree Growth And Water Use Efficiency During The Twentieth Century: From Global Trends To Local Drivers, Justin Michael Mathias

Graduate Theses, Dissertations, and Problem Reports (ETD)

The frequency and severity of extreme environmental conditions will continue to increase under global environmental change. How terrestrial plants respond to prolonged, and often novel environmental stressors, will have profound impacts on, and feedbacks with, the Earth climate system at local to continental scales. Central to these feedbacks are plant stomata, actively regulated pores on the leaves of plants that act as a control valve over the fluxes of carbon dioxide (CO₂) into the leaf during photosynthesis and water vapor (H₂O) out of the leaf during transpiration. Importantly, changes in stomatal aperture do not affect the …

Impact Of Sire Selection And Breed On Parasite Resistance In Sheep, Andrew Ryan Weaver

Graduate Theses, Dissertations, and Problem Reports (ETD)

Selection within and among breeds are strategies to mitigate the impact of parasitism given failing chemotherapeutics. While Texels have improved marketability compared to other parasite-resistant breeds, the mechanism by which Texels reduce fecal egg count (FEC) is unclear. The immune response to Haemonchus contortus (Hc) was compared in Texel, parasite-resistant St. Croix, and parasite-susceptible Suffolk sheep. Adult worms exposed to St. Croix- and Texel-derived peripheral blood mononuclear cells and serum in vitro had greater binding around the reproductive structures than Suffolk and worm egg release tended to be affected by breed (P = 0.09). Resistance in Texels …

The Exploration Of Nanotoxicological Copper And Interspecific Saccharomyces Hybrids, Matthew Joseph Winans Phd

Graduate Theses, Dissertations, and Problem Reports (ETD)

Nanotechnology takes advantage of cellular biology’s natural nanoscale operations by interacting with biomolecules differently than soluble or bulk materials, often altering normal cellular processes such as metabolism or growth. To gain a better understanding of how copper nanoparticles hybridized on cellulose fibers called carboxymethyl cellulose (CMC) affected growth of Saccharomyces cerevisiae, the mechanisms of toxicity were explored. Multiple methodologies covering genetics, proteomics, metallomics, and metabolomics were used during this investigation. The work that lead to this dissertation discovered that these cellulosic copper nanoparticles had a unique toxicity compared to copper. Further investigation suggested a possible ionic or molecular mimicry …

Mnemonic Discrimination And Social Anxiety: The Role Of State Anxiety, Gabriella T. Ponzini

Graduate Theses, Dissertations, and Problem Reports (ETD)

The Mnemonic Similarity Task (MST) measures mnemonic discrimination, or the ability to correctly identify new stimuli from highly similar, old stimuli. Neuroscientific and theoretical suppositions suggest that poor mnemonic discrimination may represent a potential risk or maintenance factor for anxious individuals. However, state affect appears to moderate the relation between mnemonic discrimination abilities and trait anxiety. The current study aimed to elucidate the nascent research on mnemonic discrimination and anxiety by evaluating the MST in a specific subtype of anxiety (i.e., social anxiety) and utilizing a clinically relevant stressor task (i.e., knowledge of a future speech). Participants (N = …

Neuroimaging Of Real-World Audio-Visual Sensory Integration In High-Functioning Autism, Paula J. Webster

Graduate Theses, Dissertations, and Problem Reports (ETD)

Sensory processing differences are a prevalent aspect of autism spectrum disorder (ASD) that may contribute to core deficits of ASD such as repetitive behaviors as well as comorbidities including anxiety disorders. The ability to integrate information among our senses is required to comprehend the world around us and is crucial for the development of language, motor skills, and social communication. Prior studies have shown that individuals with autism differ from individuals without autism when presented with simple, non-natural audio-visual stimuli such as basic shapes accompanied by pure tones. Because the human brain processes non-natural and natural stimuli differently, more recent …

Role Of Ciliary Proteins Adp Ribosylation Factor Like Gtpase 13b (Arl13b) And Bardet-Biedl Syndrome-8 (Bbs8) In Photoreceptor Outer Segment Morphogenesis, Maintenance, And Viability, Tanya L. Dilan

Graduate Theses, Dissertations, and Problem Reports (ETD)

Photoreceptor neurons are modified primary cilia with an extended ciliary compartment known as the outer segment (OS). The mechanisms behind the elaboration of photoreceptor cilia, OS morphogenesis, and maintenance remain poorly understood. In this work, we focused on dissecting the role of two ciliary proteins, the small GTPase ADP-ribosylation factor-like GTPase 13B (ARL13B) and Bardet-Biedl Syndrome-8 (BBS8) in the context of photoreceptor biology. Both BBS8 and ARL13B are linked to defects in ciliogenesis (cilia development) and Retinitis Pigmentosa (vision loss). ARL13B is implicated in regulating ciliary length, and BBS8 is part of the Bardet-Biedl Syndrome complex (BBSome); the BBSome is …

Utilizing Conservation Genetics As A Strategy For Recovering The Endangered Candy Darter (Etheostoma Osburni) In West Virginia, Brin E. Kessinger

Graduate Theses, Dissertations, and Problem Reports (ETD)

The Candy Darter (Etheostoma osburni) is a small freshwater fish native to the New River drainage in West Virginia and Virginia that was listed as endangered in November 2018. It has been extirpated from much of its historic range in West Virginia, restricting it to the Gauley and Greenbrier river drainages. In addition to extirpations, the species is threatened by introgressive hybridization with the invasive Variegate Darter (E. variatum). Previous research primarily focused on hybridization, but population genetic analyses were limited. Population genetic analyses aim to identify distinct populations through genetic structure and characterize the levels …

Alternative Media And Mulches In Organic Vegetable Production, Heather R. Griffith

Graduate Theses, Dissertations, and Problem Reports (ETD)

Reducing or eliminating waste from organic vegetable production can conserve money as well as resources. Conventional greenhouse production of vegetable transplants often relies on abundant fertigation which produces large amounts of polluted runoff, and the field production of organic vegetables frequently relies on the use of polyethylene mulch. A greenhouse study was conducted to determine if organic transplants can be successfully produced in a greenhouse under reduced soil moisture in order to reduce leaching of nutrients and potential water pollution. To test this, we compared the effect of reduced irrigation volumes to the standard practice of irrigating with 120% of …

An In-Depth Investigation Of The Effects Of Work-Related Factors On The Development Of Knee Musculoskeletal Disorders Among Construction Roofers, Amrita Dutta

Graduate Theses, Dissertations, and Problem Reports (ETD)

Construction roofers have the uppermost likelihood of developing knee musculoskeletal disorders (MSDs). Roofers spend more than 75% of their total working time being restricted to awkward kneeling postures and repetitive motions in a sloped roof setting. However, the combined effect of knee-straining posture, roof slope and their association to knee MSDs among roofers are still unknown. This dissertation aimed to provide empirical evidence of the effects of two roofing work-related factors namely, roof slope and kneeling working posture, on the development of knee MSDs among construction roofers. These two factors were assessed as potential to increase knee MSD risks in …

Graduate Theses, Dissertations, and Problem Reports (ETD)

Over the past four years the Food Justice Lab, now housed within the Center for Resilient Communities at West Virginia University, hosted a series of food access planning workshops across the state of West Virginia. Mobilizing more than 200 participants, the Nourishing Networks workshop training program was designed to build grassroots capacity for food system change. Eighty-percent of workshop participants were women and dialogues recorded at these events revealed how women are disproportionately impacted by food insecurity and disproportionately labor to repair a broken food system. Women in West Virginia are not only growing food, feeding their families, selling it …

Predictors Of Employee Engagement In Institutions Of Higher Education, Jessica Marie O'Day

Education

This study investigated predictors of employee engagement at a large public research university. Generally speaking, the typical employee is disengaged at work (Adkins, 2015), and previous research has identified burnout as a contributor to employee disengagement (Maslach et al., 2001). Full-time staff employees volunteered to participate in a four-part survey regarding their levels of employee engagement, burnout, anxiety, and physical activity. Burnout was found to be the most significant predictor of employee engagement or disengagement, however, the results of all four surveys used in the study further exposed the complicated nature of successful employee engagement strategy.

Accessing The Functional Capabilities Of The Tick Microbiome Through Metagenomics, Darin Lee Shrewsberry Jr

Graduate Theses, Dissertations, and Problem Reports (ETD)

The black-legged tick Ixodes scapularis is a common ectoparasite of animals and an obligate blood feeder, attaching to a host animal and taking a blood meal once per life stage (i.e. 3 times during its life). Unfortunately for the tick, blood represents a nutrient poor diet largely consisting of lipids and proteins but notably lacking in essential nutrients such a B vitamins (e.g., biotin, riboflavin, niacin) Other exclusive blood feeders such as the tsetse fly harbor symbiotic bacteria that provision B-complex vitamins to their host. I. scapularis harbors Rickettsia buchneri an endoparasitic bacterium that intriguingly possesses two copies of a …

A Machine Learning And Data-Driven Prediction And Inversion Of Reservoir Brittleness From Geophysical Logs And Seismic Signals: A Case Study In Southwest Pennsylvania, Central Appalachian Basin, Tobi Micheal Ore

Graduate Theses, Dissertations, and Problem Reports (ETD)

In unconventional reservoir sweet-spot identification, brittleness is an important parameter that is used as an easiness measure of production from low permeability reservoirs. In shaly reservoirs, production is realized from hydraulic fracturing, which depends on how brittle the rock is–as it opens natural fractures and also creates new fractures. A measure of brittleness, brittleness index, is obtained through elastic properties of the rock. In practice, problems arise using this method to predict brittleness because of the limited availability of elastic logs.

To address this issue, machine learning techniques are adopted to predict brittleness at well locations from readily available geophysical …
