Development Of The Teaching Twice Exceptional Students Scale, Michelle Ann Godzinski

Dissertations

Twice exceptional (2e) students are a unique population of students, who present with a wide range of strengths and weaknesses. For this reason, it is important for teachers to be trained and feel prepared to work with these students. Teacher self-efficacy has been shown to influence both student and personal outcomes (e.g. student perceptions of school, student academic success, teacher retention, etc). The Teaching Twice Exceptional Students Scale (TTESS) was developed as a way to measure teacher’s self-efficacy in regard to working with 2e students, so that districts may better identify gaps in knowledge or training that teachers may have. …

Assessing The Damage: Moral Realism And The Evolutionary Debunking Argument, Olivia Denton

Honors Theses

For millennia, prominent thinkers have believed that moral sentiments were the recognition of external, objective truths, be they of divine, Platonic, or natural origin. Now the challenge is to find any objective tether at all for our evaluative judgements. The theory of evolution’s encroachment on metaethics is practically as old as Charles Darwin himself, but the more evolved version of this attack on the justification for moral realism (the position that avers the existence of objective moral truths and that we can know at least some of them) comes in the form of Evolutionary Debunking Arguments (EDAs). The (specifically, materialist) …

The Experiences Of Beginning Counselor Education And Supervision Faculty In The Supervision-Of-Supervision Relationship, Bonnie Jean Nicholson

Dissertations

This narrative study attempted to explore the experience of beginning counselor educators in providing supervision to doctoral supervisors-in-training. The need for a greater understanding of the supervision-of-supervision process is well recognized within the profession of counseling (e.g., Barker & Hunsley, 2013; Borders & Giordano, 2016). Four counselor educators in the beginning years of employment at a Council for Accreditation of Counseling and Related Educational Programs (2015) accredited counselor education and supervision doctoral program provided narratives of their own experiences providing supervision-of-supervision. Nine themes and 18 subthemes emerged from the data analysis; the following nine themes were confirmed by the participants …

Decision Making By The Prefrontal Cortex And The Role Of Dopamine In Pyramidal Neuron Function, Nesrien Muftah Milad Mohamed

Dissertations

There were two primary focuses of this research. The first aim was to investigate how students’ perception toward the flipped classroom and video learning correlate to their characteristics including their demographics, first generation status, English language learner status, Grit level, motivation types, quality of peer collaboration, and social self-efficacy. Our data indicated that there is significant correlation between student’s motivation status and attitude toward learning from video lectures. The intrinsically motivated students have a higher attitude toward learning from video. This study also demonstrates that participants with high Grit scores performed better than the participants with low Grit scores. The …

The Impact Of Rater Effects On Decision Consistency And Decision Accuracy Under The Many-Facet Rasch Measurement Framework, Haussohou Daniel Edi

Dissertations

The rise of performance-based assessments in high-stakes licensure examinations has brought many challenges in the field of measurement. Although examiners are commonly trained to apply a standardized rating of examinees, the introduction of human subjectivity to the measurement process poses a threat to the reliability and validity of scores from these assessments (Wind & Guo, 2021). Considering the high-stakes decisions based on performance-based assessments when they are used for licensure, it is essential to provide evidence of the consequences that rater effects have on decision consistency and decision accuracy, within and across rating designs.

Etiology And Epidemiology Of Mini-Ring In Ultradwarf Bermudagrass Putting Greens, Lukas Dant

All Dissertations

Mini-ring is a disease in ultradwarf bermudagrass (UDBG) [Cynodon dactylon (L.) Pers. × C. transvaalensis (Burtt-Davy)] putting greens caused by Waitea zeae (Voorhees) J.A. Crouch & Cubeta, (formerly Rhizoctonia zeae). Symptoms typically resemble frog-eye patches that are 10 to 40 cm in diameter with a bronze to orange outer ring and green center. In the southeastern United States, mini-ring symptoms appear in late-summer and generally persist until UDBG dormancy in late-fall. Mini-ring is often problematic in UDBG when nitrogen (N) fertility is reduced to manage organic matter production and improve putting green performance and perceived green speed. While …

Carbon Fibers From Bio-Based Precursors Derived From Renewable Sources, Sagar Kanhere

All Dissertations

Carbon fibers have the highest strength and modulus among all known fibers and are used as reinforcements in high-performance composites [1]. Carbon fibers also have a very low density relative to metals. Therefore, carbon fibers possess ultrahigh specific strength and modulus, which make them desirable for high-performance light-weight composites. A vast majority of commercial carbon fibers are produced from PAN precursors that are expensive, which limits the use of PAN-derived carbon fibers to aerospace applications (e.g., airplanes). However, for costsensitive applications, there is a need for low-cost, moderate performance carbon fibers. Lignin is a low-cost by-product of pulping and biorefining …

The Effects Of The Avid Program On Rural Student Growth In Middle Grades Mathematics, James Allen

All Dissertations

From this mixed method study, I present my findings on the effects of selected aspects of the Advancement Via Individual Determination (AVID) program on rural middle school students’ mathematics achievement. Previous research on the AVID program has focused on implementation in urban schools, although rural communities’ student populations continue to grow.

Most research on AVID’s success in urban settings show positive correlations between how long students participate in the AVID program and their college readiness. Other research about predictors of college success shows students who do not enroll in advanced level mathematics courses in middle school are less likely to …

Computational And Experimental Investigations Of Alkali Cation Interactions At The Rutile – Water Interface, Isaac Johnston

All Dissertations

Overall, the objective of this dissertation was to investigate the degree of sorption for the alkali cations on rutile to ascertain the impact of different cation properties, such as ion size and charge density, on sorption mechanics as well as probe how the ion may alter the surface – aqueous interface. Initial molecular dynamic simulations and batch experiments showed minimal surface sorption for any alkali cation at relatively low concentrations while simultaneously suggesting the enthalpy of deprotonation shifts slightly in the presence of the alkali cations at different ionic strengths. The cations are likely causing small reorientations of the near-surface …

Development Of Enzyme-Responsive Polymersomes As A Drug Delivery System For Gm1 Gangliosidosis, Bipin Chakravarthy Paruchuri

All Dissertations

GM1 gangliosidosis is a lysosomal storage disorder caused by deficiency of β-galactosidase (βgal) and subsequent accumulation of GM1 ganglioside in lysosomes. The rare nature of this disorder presents challenges with prognosis and treatment. Enzyme replacement therapy (ERT) can effectively treat systemic deficiencies, but the intravenously administered enzyme cannot cross the blood-brain barrier (BBB) to treat the central nervous system. A delivery system to encapsulate and deliver the enzyme can facilitate enzyme transport across the BBB with suitable surface modifications. One of the pathological aspects of GM1-affected cells is the upregulation of the lysosomal enzyme hexosaminidase A (HexA). In this dissertation, …

Uni-Prover: A Universal Automated Prover For Specificationally Rich Languages, Nicodemus Msafiri John Mbwambo

All Dissertations

Formal software verification systems must be designed to adapt to growth in the scope and complexity of software, driven by expanding capabilities of computer hardware and domain of potential usage. They must provide specification languages that are flexible and rich enough to allow software developers to write precise and comprehensible specifications for a full spectrum of object-based software components. Rich specification languages allow for arbitrary extensions to the library of mathematical theories, and critically, verification of programs with such specifications require a universal automated prover. Most existing verification systems either incorporate specification languages limited to first-order logic, which lacks the …

Program Planning On Social Determinants Of Health For Rural Nebraska, Maria H. Cantu Hines

Capstone Experience: Master of Public Health

Social determinants of health (SDOH) are non-health factors that impact health in both direct and indirect ways. Research into SDOH and their effects has been extensive in recent years and has been further documented by the COVID-19 pandemic. Despite the wealth of the literature on the SDOH, awareness of these important factors is not prevalent among community residents. Rural communities are as subject to the impact of SDOH just as their urban counterparts and experience additional complexities related to geography and topography.

This capstone project aims to raise awareness, provide education, and assist with tools and resources, to empower rural …

Committed To Commitment: The Problem With Washington State’S Involuntary Treatment Act, Hannah Garland

Washington Law Review

Washington State utilizes the Involuntary Treatment Act (ITA) to civilly commit individuals experiencing behavioral health crises. Although civil commitment involves stripping away fundamental rights, it receives less attention than criminal incarceration. The ITA is meant to protect not just the general community, but also the rights of people with behavioral health disorders who utilize the ITA system. Yet, its implementation tells a different story. Individuals in King County are detained and committed repeatedly, without receiving consistent care. Furthermore, the ITA disproportionately impacts unhoused individuals and Black individuals. As the ITA continues to grow both in utilization and expense, other community-based …

Finite Element Approach On Minimization Of Cracks At I-Girder Ends Induced By Prestress, Sangit Rauniyar

Civil Engineering Dissertations - Archive

Prestressed I-girders are one of the very commonly and widely used girders for bridges. It is produced at precast plant and transported to bridge site. To produce a prestressed I-girder, strands are first pulled and concrete is poured in I-girder’s formwork. Once the concrete reaches a desired strength, strands are released which induce prestress in I-girder. There are mainly two types of design for I-girders-one that requires debonding of strands at the end of I-girders and another that requires harping of strands at the end of I-girders. The debonding and harping of strands are done to reduce tension at the …

The Effect Of Aphantasia On Visual Memory Retention, Joshua M. Bain

Longwood Senior Theses

Aphantasia is the inability to create mental imagery which affects approximately 2% of people in the world (Zeman et al., 2015). The vividness of visual imagery questionnaire (VVIQ) was used to sort participants into four groups (aphantasia, low, medium, and high vividness) based on their vividness score with aphantasia participants scoring a 16 (the minimum). I tested the effect of aphantasia on scores of a visual memory recall test. Participants saw two of six possible images and answered five questions per image.

Identifying And Minimizing Underspecification In Breast Cancer Subtyping, Jonathan Cheuk-Kiu Tang

Master's Theses

In the realm of biomedical technology, both accuracy and consistency are crucial to the development and deployment of these tools. While accuracy is easy to measure, consistency metrics are not so simple to measure, especially in the scope of biomedicine where prediction consistency can be difficult to achieve. Typically, biomedical datasets contain a significantly larger amount of features compared to the amount of samples, which goes against ordinary data mining practices. As a result, predictive models may fail to find valid pathways for prediction during training on such datasets. This concept is known as underspecification.

Underspecification has been more accepted …

Design Of A System To Investigate The Relationship Between Feedback And Delivery Medium For A Novel Motor Task, Ashley Humpal

Master's Theses

Stroke is a chronic, lifelong illness, and full recovery requires continuous physical and cognitive rehabilitation. Such long-term rehabilitation is cost-prohibitive; however an approach to providing long-term therapy that has recently gained traction is the use of socially assistive agent (SAA) systems. These systems make use of non-contact communication devices and can be used to guide people through a variety of rehabilitative tasks. They have the potential supplement current rehabilitation practices by providing motivation during intense exercises, and can extend the reach of the therapist into remote and home settings.

Though SAA systems have been used in a variety of rehabilitative …

Effects Of Atomic Oxygen On Outgassing Of Silicone Materials, Samuel Westrick

Master's Theses

An important consideration for spacecraft material selection is the space environment that the spacecraft will be operating in. Two features of the space environment that drive material selection are material outgassing and the presence of atomic oxygen in low Earth orbit (LEO). Materials that are considered for use in space are tested to be able to understand how they’ll outgas on orbit and how they’ll respond to interactions with atomic oxygen. However, testing to understand how atomic oxygen interaction with a material will affect how the material will outgas is rare and not standardized. This thesis used a vacuum chamber …

A Study On The Effects Of Cementless Total Knee Arthroscopy Implants' Surface Morphology With Finite Element Analysis, Peter Hunt

Master's Theses

Total knee arthroscopy is one of the most performed and most successful orthopedic surgeries, with nearly a million procedures performed in 2020 in the United States alone. Due to changing patient demographics, the use of cementless fixation for implant stability is becoming more prevalent amongst recipients. Cementless implants rely on the surface morphology of a porous coating to bond implant to bone; the quality of this bond is dependent on an interference fit and the roughness, or coefficient of friction, between implant and bone. Stress shielding is a comparison of the properties in implanted bone to natural bone; it is …
