Disturbance Related To Unconventional Oil And Gas Development In The Appalachian Basin, Kevin Jordan Harris

Graduate Theses, Dissertations, and Problem Reports (ETD)

Little research has been done on the land cover change of unconventional oil and gas (UOG) wells across the Appalachian basin. In the last decade, UOG development has increased drastically across the region. Permitted well data from 2007 to 2017 were assembled into a geospatial database and analyzed with current aerial imagery to determine the activity of permitted wells in Ohio, Pennsylvania, and West Virginia. To capture all disturbance related to UOG development, a 25-hectare buffer was placed around each active well as the study extent. A supervised classification approach was used to determine the pre-development and post-development landcover across …

Addiction Or Disorder? Using The Bias Map Model To Explain The Stigmatizing Effects Of News Media Labels For Opioid Use Disorder, Kylie J. Wilson

Graduate Theses, Dissertations, and Problem Reports (ETD)

The stigma surrounding opioid use disorder is often reinforced by the language that the general public and institutions use to talk about people with the disorder. Consistent with labeling theory, contending that labels are vehicles for social categorization and stereotypes, triggering bias, (e.g., Ashford, Brown, Ashford, & Curtis, 2019; Corrigan, Kuwabara, & O’Shaughnessy, 2009; Goodyear, Haass-Koffler, & Chavanne, 2018; Link & Phelan, 1999) but the ingroup based cognitive and emotional process through which these affect public stigma has not been explored in detail. This dissertation employs the Stereotype Content Model (SCM) and the Behaviors from Intergroup Affect Stereotypes (BIAS) Map …

Validation Of Fast Spectrochemical Screening Methods For The Identification Of Counterfeit Pharmaceutical Packaging, Emily Ann Haase

Graduate Theses, Dissertations, and Problem Reports (ETD)

Counterfeit pharmaceuticals are an actively developing health and economic threat worldwide. Particularly prevalent are counterfeit pharmaceuticals distributed in emerging nations and through internet pharmacies or e-pharmacies. Although technology has been developed that discourages anti-counterfeiting practices (such as optically variable devices, invisible ink, and track-and-trace technology), it remains somewhat novel and expensive to implement on a widespread scale.

In this study, Laser Induced Breakdown Spectroscopy (LIBS) and Attenuated Total Reflectance-Fourier Transform Infrared Spectroscopy (ATR-FTIR) were proposed as fast and non-invasive tools for the identification of counterfeit pharmaceutical packages. The main objective of this research was to develop and evaluate the capabilities …

Galvanizing Germantown: The Politicization Of Louisville's German Community, 1848-1855, Ann Kathryn Fleming

Graduate Theses, Dissertations, and Problem Reports (ETD)

This project interprets the Revolutions of 1848 and their ideological legacy through a transnational and transcultural context, highlighting the role of radical forty-eighters who imparted their republican messages to “Little Germanies” within the United States. Karl Heinzen serves as the primary example of the transient group that shared their radical visions with local German communities populated with political and cultural organizations, an active press and a commitment to civic engagement demonstrated through their involvement anti-slavery groups, labor reform, and improved rights for the immigrant population.

The thesis traces the politicization of Karl Heinzen in the German Confederation and his involvement …

Top-Down Model Development Using Data Generated From A Complex Numerical Reservoir Simulation With Water Injection, Yvon Andrea Martinez

Graduate Theses, Dissertations, and Problem Reports (ETD)

Numerical simulation and data-driven modeling are two current approaches in engineering reservoir modeling. Numerical reservoir simulation attempts to match past production history by modifying reservoir properties of the model. After multiple computationally intensive trial and error efforts, accurate history matches are identified. These history matches are used by project management for production forecasting purposes. Data-driven reservoir modeling utilizes measured data and is, therefore, free of assumptions that are often included in numerical reservoir simulations. Artificial intelligence and machine learning algorithms are technologies implemented in the development of a data-driven reservoir model with efforts to learn fluid flow through porous media …

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 …

“I Don't Really Look Very Asian”: Transracially And Transnationally Adopted Asian Youth In Rural Appalachia, Sandra L. Rodeheaver

Graduate Theses, Dissertations, and Problem Reports (ETD)

Transracially adopted Asian children in rural Appalachia find themselves adopted into places where there is little or no racial and ethnic diversity. In this context, it may be difficult to transgress the model minority stereotype and systemic racism in schools and the community. There are particular issues and concerns related to racial identity for TRAAs that may make the task of becoming fully integrated members of the community challenging. Building on the literature on transracial and transnational adoption, this study aims to better understand the lives and perspectives of two transracially adopted Asian (TRAA) girls living in rural Appalachia and …

Occurrence, Mating Strategy, And Pathogenicity Of Members Of Nectriaceae In Central Appalachia, Cameron Michael Stauder

Graduate Theses, Dissertations, and Problem Reports (ETD)

Members of the Nectriaceae occupy many ecological niches including dominant canker pathogens, such as Neonectria ditissima and N. faginata. These two pathogens contribute to the decline of American beech (Fagus grandifolia) forests across the Appalachian Mountains due to beech bark disease (BBD). Interestingly, N. ditissima represents a well-known canker pathogen many hardwood species, while N. faginata has not been observed outside of BBD. Additionally, N. faginata occurs at higher incidences than N. ditissima in BBD stands. Nectriaceae in Central Appalachia were surveyed as to further characterize the diversity and possibly identify a non-beech host of N. faginata. …

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 …

Improvement Of Tcad Augmented Machine Learning Using Autoencoder For Semiconductor Variation Identification And Inverse Design, Kashyap Mehta, Sophia Susan Raju, Ming Xiao, Boyan Wang, Yuhao Zhang, Hiu Yung Wong

Faculty Research, Scholarly, and Creative Activity

A machine learning (ML) model by combing two autoencoders and one linear regression model is proposed to avoid overfitting and to improve the accuracy of Technology Computer-Aided Design (TCAD)-augmented ML for semiconductor structural variation identification and inverse design, without using domain expertise. TCAD-augmented ML utilizes TCAD simulations to generate sufficient data for ML model development when experimental data are inadequate. The ML model can then be used to identify semiconductor structural variation for given experimental electrical measurements. In this study, the variation of layer thicknesses in the p-i-n diode is used as a demonstration. An ML model is developed to …

Energy Filtering Effect At Source Contact On Ultra-Scaled Mosfets, Johan Saltin, Nguyen Cong Dao, Philip H.W. Leong, Hiu Yung Wong

Faculty Research, Scholarly, and Creative Activity

We postulate that in ultra-scaled Field Effect Transistors (FET), such as nanowires in sub-7nm technology, the source contact will act as an energy filter and increase the effective temperature of carriers arriving at the channel barrier. This is due to the absence of inelastic scattering in the short source-contact-to-channel region. As a result, the Sub-threshold Slope (SS) will increase substantially. In this paper, we verify this energy filtering effect through numerical calculations and Technology Computer-Aided-Design (TCAD) simulations calibrated to quantum solvers for electrostatics. It is found that SS degradation increases as the source metal workfunction increases. At 300K, in the …

Spatial Particulate Fields During Highwinds In The Imperial Valley, California, Frank R. Freedman, Paul English, Jeff Wagner, Yang Liu, Akula Venkatram, Daniel Q. Tong, Mohammad Z. Al-Hamdan, Meytar Sorek-Hamer, Robert Chatfield, Ana Rivera, Patrick L. Kinney

Faculty Research, Scholarly, and Creative Activity

We examined windblown dust within the Imperial Valley (CA) during strong springtime west-southwesterly (WSW) wind events. Analysis of routine agency meteorological and ambient particulate matter (PM) measurements identified 165 high WSW wind events between March and June 2013 to 2019. The PM concentrations over these days are higher at northern valley monitoring sites, with daily PM mass concentration of particles less than 10 micrometers aerodynamic diameter (PM10) at these sites commonly greater than 100 μg/m3 and reaching around 400 μg/m3, and daily PM mass concentration of particles less than 2.5 micrometers aerodynamic diameter (PM2.5) commonly greater than 20 μg/m3 and …

The Assembly History Of The Nearest S0 Galaxy Ngc 3115 From Its Kinematics Out To Six Half-Light Radii, Arianna Dolfi, Duncan A. Forbes, Warrick J. Couch, Anna Ferre-Mateu, Sabine Bellstedt, Kenji Bekki, Jonathan Diaz, Aaron J. Romanowsky, Jean P. Brodie

Faculty Research, Scholarly, and Creative Activity

Using new and archival data, we study the kinematic properties of the nearest field S0 galaxy, NGC 3115, out to ∼6.5 half-light radii (Re) from its stars (integrated starlight), globular clusters (GCs), and planetary nebulae (PNe). We find evidence of three kinematic regions with an inner transition at ∼0.2 Re from a dispersion-dominated bulge (Vrot/σ < 1) to a fast-rotating disc (Vrot/σ > 1), and then an additional transition from the disc to a slowly rotating spheroid at ∼ 2-2.5Re, as traced by the red GCs and PNe (and possibly by the blue GCs beyond ∼ 5Re). From comparison with simulations, we propose an assembly history in which …

Investigating The Relationship Between Self-Efficacy And Cardiopulmonary Resuscitation Quality In Certified Athletic Trainers, Lucas William Lammert

Health Nutrition and Exercise Science

Certified athletic trainers (ATCs) are often the first to respond to an athletic sudden cardiac arrest (SCA) and are expected to administer the highest quality of cardiopulmonary resuscitation (CPR) possible. The goal of this study was to investigate the relationship between confidence and CPR quality in ATCs. Fifty ATCs completed confidence questionnaires before and after performing a prolonged CPR assessment on a medium-fidelity manikin. CPR data included measures of chest compression and ventilation quality. Data were analyzed to compare confidence levels pre- and post-CPR assessment, as well as to determine the relationship between CPR performance and self-efficacy. A small, negative …

Methods: Twelve professional modern dancers (8 female, 4 male) participated in this study. Two force plates were utilized to record the force-time data during drop jumps (DJ) before and after an acute, fatiguing protocol. Dancers performed a 5-10 minute self-selected warm up followed by 3-5 practice trials of DJs onto the force plates. Three trials were recorded from each dancer with 30-60 seconds (s) of rest between trials. …

Using Blockchain For Digital Card Game, Raymond A. Swannack

EWU Masters Thesis Collection

In recent years, the popularity of both online card games and blockchain technology have grown exponentially. While combining these two does not immediately seem like an obvious idea, they in fact complement each other nicely. Blockchain allows for players to actually own their cards, in a way that was unheard of in the digital format just a few years ago. It also gives them the freedom to use them in any way they like, just like in real life. In this thesis we will look into how viable this idea really is. We use the Ethereum virtual machine to simulate …

Owner Perceptions Of Cat-Human Communication, Kendal Cler

EWU Masters Thesis Collection

This study focuses on cat to human communication with an emphasis on the way humans perceive cats' communicative signals. Compared to other animals, the domestication of cats has been a slow process and humans have begun to recognize the communicative signals from cats and vice versa. Based on the results of this survey research, humans have started to notice different forms of communication from cats, and are able to decipher their cat’s needs, most of the time. Owners of cats in this study appear to be projecting human values of communication onto their cats. Cats have begun to adjust their …
