Using Professional Development As A Tool To Build Teacher Capacity For Recognizing Giftedness In African American Students, Dr. Jacqueline D. Drye

Dissertations, Theses, and Masters Projects

African American students are underrepresented in gifted programs in American public schools. This is due in part to the teachers’ role in the gifted identification process. Classroom teachers are asked to refer students for evaluation for gifted services. To effectively do this, teachers must understand the unique challenges faced by gifted students from diverse populations, be able to recognize potential and be willing to explore their own perceptions about giftedness. When considering the historical plight of African Americans and their quest for an equitable education, coupled with current statistics on income, employment and educational attainment, the need to address this …

Social Media And Professional Learning, Tiffany Truitt

Dissertations, Theses, and Masters Projects

Although research indicates professional learning could positively influence both teacher retention and student achievement, many educators continue to express dissatisfaction with professional learning experiences. In a Virginia Department of Education (VDOE, 2019b) survey, teachers at Roth High School expressed issues with misalignment between the content of professional learning offerings and their specific learning needs, a lack of follow-up implementation support, and a failure to see an effect on student achievement. Using Guskey’s (2000) Five Levels of Professional Development Framework, which uses a leveled approached to assessing professional learning, this action research study sought to achieve a better understanding of the …

Policy Recommendations For Tire Additive 6ppd And Its Derivative 6ppd-Q, Ashley E. King

Dissertations, Theses, and Masters Projects

Around 3.1 billion tires are produced around the world annually1. The antioxidant additive, 6PPD (i.e., N-(1,3-dimethylbutyl)-N’-phenyl-p-phenylenediamine) is widely employed in passenger and commercial vehicle tires at 0.4-2% by mass to impede tire degradation2. Antioxidants are intended to migrate to tire surfaces and form protective films to prevent rubber oxidation. 6PPD is designed to react with oxidant species like ozone, intentionally forming chemical transformation products that can then escape from the tire and into the environment. 6PPD-Q (i.e., 2-anilino-5-[(4-methylpentan-2-yl)amino]cyclohexa-2,5-diene-1,4-dione) is one such transformation product.

After release and disbursement in the environment, 6PPD-Q is bioavailable to aquatic animals and mammals and acute …

Accessibility And Inclusivity In Marine Science Education: A Suite Of Collaborative Marine Science Lesson Plans, Amy Nicholson

Dissertations, Theses, and Masters Projects

Excerpt from capstone: "Marine science education is oftentimes sparse in formal education. This is due to a myriad of factors, including but not limited to: minimal state marine science curricula standards, geographic restraints, and lack of resources. This problem is not just unique to marine science, either. In 2018, it was found that only two states required environmental science in secondary education, with just eight requiring general earth and space science (American Geosciences Institute 2018). To further this disparity, marine science curricula are often focused on upper grade levels, with most marine science curricula being focused on the 10th grade …

Considering Tidal Flooding To Provide A Holistic Approach To Nutrient Input Management, Mary Beth Armstrong

Dissertations, Theses, and Masters Projects

This report explores the integration of tidal flooding impacts into nutrient management frameworks for the Chesapeake Bay, a potentially large gap in current strategies. Coastal communities in the Chesapeake Bay, face an increasing threat from tidal flooding—also known as sunny-day flooding—which occurs without rainfall. In 2023, Norfolk, Virginia experienced 10 days of tidal flooding, but forecasts indicate that by 2075 the area could be experiencing tidal flooding every day. Recent research highlights that even a single tidal flooding event can introduce substantial nutrient loads into the Bay, sometimes exceeding the annual nutrient allocations. This significant increase in both the frequency …

A Program Evaluation Of I-Ready Implementation In A North Carolina Middle School, Juliana Irene Owen Thompson

Dissertations, Theses, and Masters Projects

Aurelius School District used Curriculum Associates’ i-Ready program, which was philosophically aligned to the science of reading and included i-Ready Diagnostic, i-Ready Instruction, and Teacher Toolbox, to improve Cole Middle School students’ reading achievement. Because of the high monetary cost of i-Ready, the school district was considering changing or ending this program. This pragmatic, mixed methods design, CIPP (Stufflebeam, 2003) program evaluation analyzed the fidelity of implementation of the i-Ready program through descriptive statistics (frequencies); assessed the effectiveness of the i-Ready program in increasing student achievement (on the Diagnostic, NC Check-Ins, and NC EOG) through descriptive statistics (mean, standard deviation, …

Characterizing Changes In Participation And Diversification In Virginia's Small-Scale Commercial Fishing Industry, Shelby Brooke White

Dissertations, Theses, and Masters Projects

Small-scale fisheries represent a diverse and dynamic portion of the global commercial fishing population and serve as a source of food security, income, and livelihood for many individuals and contribute to the development of local community and regional identities. Virginia’s small-scale commercial fisheries offer similar benefits, accounting for a significant portion of the state’s total annual landings and employing thousands of individuals. Despite the value of these fisheries, the number of commercial licenses has declined over the past few decades. Declines are attributed to various factors but indicate potential shifts in participation and resource dependence that may be consequential. Similar …

A Spectral Return: Non-Metaphorical Ghosts, Monsters, And Hauntology, Kit Bauserman

Dissertations, Theses, and Masters Projects

Uses of hauntology within academic scholarship are peculiarly metaphorical and British. This project aims to combat the overabundance of such readings to create more breadth in academic discourse on the spectral. This project does not seek to replace metaphorical or British renderings of hauntology, but to exist alongside it as overreliance on a particular formulation creates detrimental limits and barriers to scholastic innovation. The first essay examines the ghosts of Theodore “Wes” Wesley and Samuel Isaac Bailey within Unwell: A Midwestern Gothic Mystery (2018-2023) and The Sheridan Tapes (2020-present). Examining these category-defying ghosts which exhibit mass, warmth, and breath through …

Exploring Software Licensing Issues Faced By Legal Practitioners, Nathan James Wintersgill

Dissertations, Theses, and Masters Projects

Most modern software products incorporate open source components, which requires compliance with each component’s licenses. As noncompliance can lead to significant repercussions, organizations often seek advice from legal practitioners to maintain license compliance, address licensing issues, and manage the risks of noncompliance. While legal practitioners play a critical role in the process, little is known in the software engineering community about their experiences within the open source license compliance ecosystem. To fill this knowledge gap, a joint team of software engineering and legal researchers designed and conducted a survey with 30 legal practitioners and related occupations and then held 16 …

Program Analysis For Software Engineers And Students, Jialiang Tan

Dissertations, Theses, and Masters Projects

Software inefficiencies are inevitable in computer systems. At the code level, software packages have become increasingly complex, they are comprised of a large amount of source code, sophisticated control and data flow, and growing levels of abstraction. This complexity often introduces inefficiencies across software stacks, leading to performance degradation. At the resource level, the evolution of hardware outpaces the performance optimization of software, leading to resource wastage and energy dissipation in emerging architecture. To better understand program behaviors, software developers take advantage of performance profiling tools. Existing profiling techniques, whether fine-grained profilers or coarse-grained profilers focus on identifying hotspots, which …

Environmental Education In The Classroom: Selected Early-Career Teachers' Experiences Navigating Pre-Service And In-Service Activity Systems, Sarah Mcguire Nuss

Dissertations, Theses, and Masters Projects

Recent publications argue that to prepare teachers of all grade levels to be confident and competent in incorporating environmental education into their classrooms, pre-service teacher training is effective (e.g., J. T. McDonald & Dominguez, 2010). But the systems in which teachers learn and work are complex, making professional learning about, and implementation of, environmental education both disparate and limited (Franzen, 2017). This study sought to understand the nature of participants’ experiences within and between teacher preparation and in-service learning systems as they relate to environmental education. Cultural historical activity theory (CHAT) provided a framework to allow for deeper understanding of …

Artificial Illumination Of Trawl Gear Components To Reduce Pacific Halibut (Hippoglossus Stenolepis) Bycatch In The U.S. West Coast Groundfish Bottom Trawl Fishery, Derek Jackson

Dissertations, Theses, and Masters Projects

Pacific halibut (Hippoglossus stenolepis) is a prohibited species for the U.S. West Coast Bottom Trawl Fishery and in the last decade, there has been a concentrated interest in the use of artificial illumination serving as a potential bycatch reduction device. Previous studies conducted off the coast of Oregon have found that the addition of green light-emitting diodes to the bridles of low-rise, cutback trawls greatly reduced the number of Pacific halibut caught. However, recent regulation changes now permit high-rise trawls, a gear configuration that fishes a very different volume of water than the previously permissible gear profile, in areas where …

The Enduring Mystery At Town Creek: New Interpretations At A Rural North Carolina Museum, Elizabeth Henry

Dissertations, Theses, and Masters Projects

Town Creek Indian Mound is a rural museum and historic site located in Montgomery County, North Carolina. Archaeological excavations at Town Creek historic site have occurred in varying capacities for nearly ninety years. Since 1955, Town Creek’s museum has served to represent archaeological endeavors occurring at the historic site. Therefore Western-trained and white archaeologists have been the sole voices presented within the museum space. Town Creek’s current museum exhibits are stuck in a state of pastness, only representing a small portion of Native lifeways; namely discourse on ritual, ceremony, and death. Current exhibits and historical interpretations at Town Creek’s museum …

Landscapes Of Silence At The First Baptist Church, Victoria R. Gum

Dissertations, Theses, and Masters Projects

The Historic Area of Colonial Williamsburg is often presented as a “town which time passed by” (Yetter 1988:30). This narrative implies that the museum landscape reflects the actual past and that restoration efforts simply returned the town to the way it used to be. However, the Restoration was accomplished according to specific ideological goals. Colonial Williamsburg was created as a shrine to traditionalist, conservative values (Greenspan 2002; Handler & Gable 1997; Lindgren 1989; Lindgren 1993) which are intrinsically linked to the global structure of systemic White supremacy. These values were enacted during the Restoration, as Black residents of the future …

Ecosystem Transitions And State Changes Rapidly Alter The Coastal Carbon Landscape: Evidence From The Chesapeake Bay Region, Alexander Jason Smith

Dissertations, Theses, and Masters Projects

The coastal landscape is a naturally shifting mosaic of distinct ecosystems that are rapidly migrating with climate change. While directional changes in climate, such as warming and sea level rise, are fundamentally reorganizing the coastal landscape, ecosystem function, especially carbon storage, is affected to an unknown degree. This dissertation presents four chapters that examine the role of ecosystem transitions in coastal carbon dynamics across a range of spatial scales – within individual ecosystems, between two ecosystems, and at the landscape between an array of ecosystems. Ghost forests, or the marsh-forest ecotone, serves as an ideal example of a migratory ecotone. …

A Reevaluation Of Why Crypto-Detectors Fail: A Systematic Revaluation Of Cryptographic Misuse Detection Techniques, Scott Marsden

Dissertations, Theses, and Masters Projects

The correct use of cryptography is central to ensuring data security in modern software systems. Hence, several academic and commercial static analysis tools have been developed for detecting and mitigating crypto-API misuse. While developers are optimistically adopting these crypto-API misuse detectors (or crypto-detectors) in their software development cycles, this momentum must be accompanied by a rigorous understanding of their effectiveness at finding crypto-API misuse in practice. The original paper presents the MASC framework, which enables a systematic and data-driven evaluation of crypto-detectors using mutation testing. MASC was grounded in a comprehensive view of the problem space by developing a data-driven …

The Role Of Stereotype And Moral Values In Predicting Victim Blaming, Jihye Choi

Dissertations, Theses, and Masters Projects

Exposing participants to a victim with different racial identities (Asian American vs. African American vs. White American) under two different types of misfortunes (poverty vs. disease), the present study aimed to find whether the victim-blaming patterns differ depending on the victim’s race and whether the difference in victim-blaming tendency could be explained by the interaction between pre-existing stereotypes and situational relevance.

Spectroscopy And Dynamics Of Atmospherically And Combustion-Relevant Collision Complexes, John Patrick Davis

Dissertations, Theses, and Masters Projects

Potential energy surfaces describing bimolecular collisions sensitively depend on the chemical functionality and the relative orientation of colliding partners, thus defining the accessibly reactive and nonreactive pathways. Herein, we investigate the peculiar product outcomes arising from Jahn-Teller distortion of the nitric oxide and methane complex (NO-CH4). We have reported an in-depth spectroscopic and dynamics study of NO-CH4 by utilizing conformation-specific and action spectroscopy, as well as velocity map imaging, to understand the fundamental dissociative mechanisms at play. Ultimately, we have gained information about how the Jahn Teller effect possibly impacts the potential product energy transfer pathways. There is a translationally …

Constraining Of The Minerνa Medium Energy Neutrino Flux Using Neutrino-Electron Scattering, Luis Zazueta

Dissertations, Theses, and Masters Projects

Long baseline neutrino oscillation experiments rely on the flux from accelerator-based neutrino beams. As experimental neutrino physics moves to the next generation of experiments a precise characterization of the neutrino flux on a given experiment becomes crucial to the goals of the experiments: to precisely determine the neutrino oscillation parameters.This work takes advantage of neutrino-electron scattering processes for their precisely predicted cross section. The observed number of scattering events can be used as a benchmark to constrain the neutrino flux. A measurement was made of the energy spectrum of neutrino-electron elastic scattering (νe-→νe-), using data from the antineutrino-enhanced run period …

The Association Between Sociodemographic Risk, Parental Substance Use, And Child Emotion Regulation Capabilities, Lydia Fay Bierce

Dissertations, Theses, and Masters Projects

Emotion regulation, defined as the ability to modulate one’s emotional experiences in order to navigate social interactions successfully and attain goals, has been associated with social competence, adjustment, and resilience during early childhood and beyond. Family-level risk factors have been linked to differences in emerging emotion regulation skills, measured at both the behavioral and physiological level. The current study investigated two familial risk factors, sociodemographic risk and parental substance use, as predictors of toddlers’ emotion regulation. Participants were 117 parent-toddler dyads recruited across a range of sociodemographic risk. Dyads completed a structured series of parent-child interaction tasks, including a resting …

Identifying Factors Controlling Dinophysis Spp. Feeding, Growth, And Toxin Production Through Field And Lab Studies, Vanessa R. Strohm

Dissertations, Theses, and Masters Projects

Harmful algal blooms (HABs) and their associated phycotoxins pose a threat to both human and shellfish health around the world. Dinophysis spp., a causative organism of diarrhetic shellfish poisoning (DSP) in humans, and its two toxin classes: dinophysistoxins (DTXs) and pectenotoxins (PTXs), have been documented throughout the year in the Chesapeake Bay. While DTX concentrations currently remain below regulatory limits in regional seafood products, further research is needed to understand environmental drivers, both biotic and abiotic, that may be impacting Dinophysis spp. feeding on prey, growth, and toxin production. To characterize populations of Dinophysis in situ, an Imaging FlowCytobot (IFCB) …

The Effect Of A Positive Story Intervention On Positivity, Stress, Hope, And Trauma Symptomatology: A Longitudinal Randomized Controlled Trial, Allison Dukes

Dissertations, Theses, and Masters Projects

The Coronavirus (COVID-19) pandemic brought many adverse effects to the global community. One effect was decreases in the mental health of college students due to forced isolations. College counseling centers, which had been experiencing long waitlists pre-pandemic, struggled to meet the demand as most had to switch to offering telehealth therapy services. Thus, the field of college counseling made a call for additional clinicians and interventions to support this population during this period of heightened need. The field of positive psychology, made popular in 2000 by Seligman and Csikszentmihalyi, focuses on how positive emotions and positivity influence our wellbeing. Additionally, …

Justice And Change: An Exploratory Case Study Of The Early Implementation Of The Restorative Justice Whole-School Model And Reculturing In A High School In The American South, Amber Weyland Rodenbo

Dissertations, Theses, and Masters Projects

Discipline inequities across racial, gender, and socioeconomic barriers are a constant in the United States, persisting long after the desegregation of schools in the last century. School divisions and schools across the United States have implemented restorative justice as an alternative to traditional punitive discipline as a potential remedy for discipline inequities. To institute whole-school restorative justice, a change in school culture, or reculturing, must occur, per Fullan’s culture of change and coherence models. Using Fullan’s models, this research was a practice-oriented exploratory case study. The following sources of data were collected: interviews with administrators, an at-will survey sent to …

The Influence Of Teacher Attribution For Challenging Behavior On Teacher Self-Efficacy And Expectations For Student Success, Mackenzie Turbeville-Mccorry

Dissertations, Theses, and Masters Projects

This study investigated how teachers’ perceptions of students demonstrating challenging behaviors are influenced by the cause of the behavior. This study measured teacher perceptions of how successful a student would be in general education, the impact a student would have on the class, and the teachers’ self-efficacy to support a student across five different attributions for challenging behavior: (a) an intellectual disability, (b) a negative attitude toward school, (c) an emotional and behavioral disability, (d) a history of trauma, and (e) autism. In Virginia, students with disabilities are disproportionately suspended, and additional inequities exist in access to an inclusive education …

A Case Study: Teachers’ Perceptions Of The Influence Of Proessional Development On Self-Efficacy Related To Implementing A Balanced Literacy Model, Kathryn Theresa Kryscio

Dissertations, Theses, and Masters Projects

Researchers have known for several years that when a child is reading below proficiency by the end of third grade, it is likely the child will continue to struggle learning to read through the child’s academic career (Dickinson & Porche, 2011; Wasik & Hindman, 2011). Yet, the problem of children falling below third grade reading proficiency continues. If teaching a child to read is a moral purpose, and it is essential for a child to read proficiently by the end of third grade, then literacy instruction in kindergarten through third grade is pivotal. In this case study, the researcher sought …

Examining Racial Differences In Psychophysiological Responses To Exposure To Police Brutality, Autumn Scarborough

Dissertations, Theses, and Masters Projects

​​​​​Despite the prevalence of police brutality videos online, research examining the effects of exposure to such videos is extremely limited. The current work examined racial differences (among both participant and victim) in psychophysiological responses to videos of police brutality. Over the course of three sessions, participants (total N = 56) responded to questionnaires measuring attitudes toward police legitimacy, trait empathy, and justification of police use of force. EEG activity was recorded while participants watched four short videos depicting real-life incidents of excessive police use of force (two with Black victims and two with White victims). We examined mu suppression, commonly …
