Effects Of Fluency-Based And Percentage-Based Mastery Criteria On Learning, Maintenance, Application, And Learner Experience In Behavior-Analytic Skill Acquisition, Marisela Alicia Aguilar

Graduate Theses, Dissertations, and Problem Reports (ETD)

In behavior analysis, staff are often trained to percentage-based criteria to demonstrate that they have mastered a skill. However, percentage-based mastery criteria may not result in long-term maintenance of the skill. In other areas of instruction, fluency criteria resulted in multiple positive outcomes such as maintenance, endurance, and application of the skill beyond the training context, but these outcomes have not yet been widely demonstrated in the context of teaching behavior support plan (BSP) content and implementation. Across two experiments, we attempted to evaluate the extent to which training individuals to a fluency-based or percentage-based criterion resulted in maintenance and …

Framing Addiction In The Age Of Vaping: A Journalism-Focused Reporting Toolkit, Jessica L. Riley

Graduate Theses, Dissertations, and Problem Reports (ETD)

This project addresses a critical gap in journalism practice: the lack of accessible, evidence-based guidance for reporting on addiction. Particularly as it relates to nicotine, tobacco and vaping. Journalists play a key role in shaping public understanding of substance use, yet existing resources often focus on opioids, lack specificity, or fail to keep pace with rapidly evolving nicotine products and scientific research. As a result, reporters may struggle with inconsistent terminology, unclear risk communication and the potential for unintentionally stigmatizing language.

Grounded in media effects theory, health communication and stigma research, this project examines how journalistic language and framing influence …

Statistical Analysis Of Evidence In Criminal Cases, Giuliana Leon Carrillo

Graduate Theses, Dissertations, and Problem Reports (ETD)

Ideally, the evaluation of relevant forensic evidence must corroborate the hypotheses that the prosecution and/or the defense holds regarding the commitment of a crime. Therefore, optimal forensic evidence would be the one that can be found all the time under the same circumstances, and cannot be found otherwise, making the forensic scientist able to evaluate this evidence given the hypotheses provided. Nevertheless, this is hard to find, as ideal evidence being only a concept.

In this project, the probabilistic interpretation of relevant forensic evidence investigated in criminal cases with the aid of Wigmore charts and Bayesian networks was proposed. Using …

Community Resilience Drives Change, Andrew Thomas Solt

Graduate Theses, Dissertations, and Problem Reports (ETD)

The opioid crisis has impacted many Americans. From 1999 to 2023, approximately 800,000 people have died due to opioid overdose (CDC, 2025). What began as overprescriptions of painkillers has quickly evolved into a complex social health issue that is now further worsened by stronger synthetic drugs like fentanyl. Fentanyl and fentanyl analogs (synthetic opioids that are very similar chemically to fentanyl) are often found in illegal drug supplies and in counterfeit pills (CDC, 2025). Thus, individuals who might have been initially overprescribed painkillers might now be pushed towards illegally produced drugs that are significantly more potent than what they were …

A Digital Calibration Source For 21 Cm Cosmology Telescopes, Kalyani Balkrishna Bhopi

Graduate Theses, Dissertations, and Problem Reports (ETD)

Precise calibration of radio telescope beams and gains is a central requirement for 21 cm intensity mapping experiments, which aim to measure large scale cosmological structure through the redshifted emission line of neutral hydrogen. Bright astrophysical foregrounds dominate the sky at these frequencies, and separating them from the cosmological signal demands precise control over instrumental systematics, particularly the telescope beam and its frequency-dependent response. Existing aerial calibration sources are incoherent broadband emitters, detectable only as total power. They provide no direct phase information and suffer from poor sensitivity in low signal-to-noise regimes.

We present the Precision Emitter for 21cm Array …

Computer Vision Methods For Rfi Segmentation In Radio Astronomy, Yechan Kweon

Graduate Theses, Dissertations, and Problem Reports (ETD)

Radio Frequency Interference (RFI) increasingly contaminates the radio astronomy spectrum, often exceeding astronomical signal amplitudes by 50–70 dB. Reliable detection and mitigation are therefore essential for studies of faint transient phenomena such as pulsars and fast radio bursts (FRBs). Existing practical methods including Spectral Kurtosis (SK), Median Absolute Deviation (MAD), and SumThreshold perform well in many settings but depend on assumptions about the RFI environment and data statistics, limiting their effectiveness for weak, broadband, or nonstationary interference.

We develop a transform based RFI detection method that requires no prior knowledge of the RFI origin or type. The method operates on …

An Assessment Of Disease Risks, Population Genetics, And Spatial Ecology Of Appalachian Cottontails (Sylvilagus Obscurus) And Snowshoe Hares (Lepus Americanus) In West Virginia, Usa, Madison Leigh Miller

Graduate Theses, Dissertations, and Problem Reports (ETD)

Snowshoe hares (Lepus americanus) occupy a large range across the United States and Canada. While snowshoe hare populations are generally considered stable in the interior of their range, populations along range edges are experiencing declines, possibly driven by climate-related factors such as seasonal coat color mismatch. West Virginia represents one of the southernmost extents of the species’ range, yet little is known about the population genetic status or population sizes of snowshoe hares in the state. Appalachian cottontails (Sylvilagus obscurus) are another lagomorph species found in West Virginia. This species experienced a historical decline and currently …

Semantic-Weighted Lidar–Camera Slam For Robust Mapping In Vegetation-Rich Environments, David Aigbovboise Akhihiero

Graduate Theses, Dissertations, and Problem Reports (ETD)

Many LiDAR odometry and SLAM methods are lightweight and effective, but they assume that all LiDAR point returns are equally reliable. In practice, this assumption is often violated in vegetation rich or semi transparent environments, where in a single beam footprint, LiDAR beams may intersect multiple scattering surfaces like leaves, branches or glass. These ambiguities in returns produces probabilistic or biased range measurements that violate the assumptions of most geometric registration frameworks and can lead to drift and inconsistency.

To address this challenge, this dissertation proposes a semantic-weighted LiDAR-camera SLAM framework that integrates class dependent weights into a front-end LiDAR …

Comparing Unet And Hrnet For Geomorphic Feature Extraction From Digital Terrain Model-Derived Land Surface Parameters, Behnam Solouki

Graduate Theses, Dissertations, and Problem Reports (ETD)

Do The Adaptogenic Mushrooms, Cordyceps Militaris And Hericium Erinaceus, Produce Caffeine-Like Discriminative-Stimulus Effects?, Stephen James Cullinan

Graduate Theses, Dissertations, and Problem Reports (ETD)

Caffeine is one of the most widely consumed drugs in the United States, but its excessive consumption increases the risk of heart disease, sleep problems, and anxiety. In response to these issues, there has been a rise in efforts to find safer alternatives to caffeine while maintaining similar subjective effects. The adaptogenic mushrooms, cordyceps and lion’s mane, are claimed to have similar energy- and mood-enhancing effects as caffeine; however, there is limited research directly comparing their effects to caffeine. A drug-discrimination paradigm, in which rats were trained to discriminate between caffeine and saline, was used to compare the discriminative-stimulus effects …

Timing, Spectral, And Single-Pulse Properties Of Radio Pulsars, Evan Francis Lewis

Graduate Theses, Dissertations, and Problem Reports (ETD)

Radio pulsars are highly magnetized, rapidly rotating neutron stars which emit beams of radio waves from their magnetic poles. Their incredible rotational stability allows for their use in a variety of high-energy astrophysical studies, though the details of their internal structure and emission mechanisms are still unknown. We use observations of a cross-section of the pulsar population in order to investigate the nature of their evolution, their emission properties, and their environments.

First we derive timing solutions for three pulsars discovered through their sporadic single pulses. It was possible to obtain timing solutions through a set of single-pulse times of …

Examining Moral Susceptibility In Ai Vs. Human-Assisted Decision-Making, Seth James Fogle

Graduate Theses, Dissertations, and Problem Reports (ETD)

Artificial intelligence (AI) systems are increasingly integrated into decision-making contexts, yet their influence on ethical judgment remains unclear. This study examines whether advice from an AI advisor, compared to a human advisor, affects moral susceptibility in a consumer decision-making scenario. Using a 2 × 2 between-subjects experimental design (advisor type × price condition), this research tests whether personal agency, perceived objectivity, and diffusion of responsibility operate as psychological mechanisms underlying ethical decision-making.

Results indicate that advisor type did not significantly influence moral susceptibility, nor did it significantly affect the proposed mediators. Additionally, the price condition did not moderate these relationships. …

Development Of Periodic Plasmonic Nano-Structures For Enhanced Labeled Bio-Sensing Systems, Kyle Zackary Smith

Graduate Theses, Dissertations, and Problem Reports (ETD)

The biomedical industry has seen sustained growth over the past half century, with a continually increasing demand for flexible, easy-to-use, and cost-effective tools. One large area of commercial interest has been point-of-use or point-of-care diagnostics, using optical based Lab-On-Chip (LOC) style systems. Label and label-free fluorescence detection systems are common benchtop modalities that have seen recent integration into these portable, cost-effective LOC applications. However, despite their maturity, there are still opportunities to improve device characteristics, specifically in reference to throughput, limit-of-detection (LOD), and hybrid integration (along with associated costs).

Optical research avenues at WVU have focused on improving these systems …
