Fabrication Of Catalyst Infused Filament For 3-D Printing Of Hybrid Rocket Fuels, Kurt C. Olsen, Stephen A. Whitmore, Brayden Barton

Small Satellite Conference

Additive manufacturing changes the electrical breakdown properties of certain 3D-printed thermoplastics like Acrylonitrile Butadiene Styrene (ABS), and when printed materials are presented with a high-voltage electrical potential, electrical-arcing along the layered surface pyrolizes the material. This electrostatic property has been harnessed to develop a High-Performance Green Hybrid Propulsion (HPGHP) technology that has capability for reliable start, stop, and re-ignition. HPGHP operates reliably using gaseous oxygen (GOX) as the complementing oxidizer; but has experienced reliability and ignition latency issues when GOX is replaced by Nytrox, a higher-density blend of nitrous oxide and GOX. Ignition issues are overcome by infusing small amounts …

Achieving Successful Outcomes In A Teleintervention Program, K. Todd Houston, Lauri Nelson, Brianna Job

Journal of Early Hearing Detection and Intervention

For well over a decade, family-centered early intervention services have been delivered through models of teleintervention (TI) to children who are Deaf and Hard of Hearing (DHH) and their families. Ongoing outcome data continue to demonstrate the viability, effectiveness, and positive impacts these services provide to both the service providers and the families served. However, to establish a successful TI program, careful planning is required, and barriers and potential roadblocks must be reduced or eliminated. When these challenges are adequately addressed, TI programs are more likely to achieve its primary goal of delivering appropriate family-centered early intervention.

Training The Next Generation Of Practitioners In Early Intervention And Telepractice: Three University Models, K. Todd Houston, Lauri Nelson, Kristina Blaiser

Journal of Early Hearing Detection and Intervention

The COVID-19 pandemic continues to shape the provision of family-centered early intervention services for children who are Deaf or Hard-of-Hearing and their families. In programs, schools, and centers, direct in-person contact with families have been significantly curtailed as a means to limit the exposure to and spead of the virus. Emergency remote learning has lead to an increase in telepractice, also referred to as teleintervention, as the designated model of service provision. Most early interventionists, speech-language pathologists, and teachers of the Deaf were not sufficiently trained to suddenly implement emergency remote teaching or telepractice services, but service providers had no …

Telepractice-Based Assessment Of Children Who Are Deaf/Hard-Of-Hearing: Focus On Family-Centered Practice, Kristina M. Blaiser, Lauri Nelson, K. Todd Houston

Journal of Early Hearing Detection and Intervention

Ongoing assessment and progress monitoring is considered best practice to serve children who are Deaf/Hard-of-Hearing (DHH) yet logistics related to provider shortages, distances between families, and illness make regular assessment difficult if not impossible. In the last ten years, telepractice has become a more commonly used service delivery model for serving children who are DHH and their families, however, many providers lack the training needed to adequately assess this population (Behl & Kahn, 2015). With explicit planning of the assessments and tools needed on both sides of the camera, providers can create a shared framework to collect the information needed …

Relationships Between Middle School Students' Adaptive Reasoning When Creating Learner-Generated Drawings And Partner Talk During Inquiry-Based Mathematical Tasks, Angela M. Frabasilio

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Adaptive reasoning is one of five components students use to develop mathematical expertise and become mathematically proficient. When students adapt their reasoning they are logically thinking about the mathematical relationships between concepts and adapting their thinking to solve problems. Three Act Math Tasks are popular math problems used in schools in which students engage in adaptive reasoning. These types of problems are beneficial to students because they engage students in inquiry-based learning, a kind of learning where students work to pose questions, interpret data, design ways to solve the problem and present their solutions. Little is known about how students …

Parent Work-Family Balance And Adolescent Psychosocial Well-Being During The Covid-19 Shutdown, Shailey Woodward

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Parents who work have many responsibilities to fulfill. They may encounter frustration and exhaustion, which can impact how well they parent. Experiences such as financial strain and the COVID-19 shutdown may further impact parenting. At the same time, adolescents are establishing identities and need attentive parents to help them develop healthy psychosocial well-being. Using Erikson’s (1968) psychosocial theory of development as a backdrop, the purpose of this study was to observe the relationships between parent work-family balance, parenting satisfaction, and adolescent psychosocial well-being within the context of financial stress and the COVID-19 shutdown. I found that parent and adolescent perceptions …

Sustain Water Conservation Behaviors Using Nonparametric Ranking And Social Marketing, Mahmudur Rahman Aveek

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Circulation of water use feedback and conservation messaging are strategies implemented to reduce water demand on a short-term (seasonal) basis. Often considered a less impactful strategy than other tactics such as price increments and usage restrictions, authorities mostly use feedback in informational campaigns with a focus to apprise users about their water use. Such conservation programs have had limited success that has been attributed to the fact that the information provided with the feedback campaigns was generic and did not motivate users enough to sustain their water-saving behaviors. However, the advent of disaggregation technologies that can provide appliance-wise water use …

Psychosocial Development In Adolescents With Disabilities: Modification And Evaluation Of Measures, Myles Maxey

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Adolescents with intellectual and developmental disabilities (IDD) are often overlooked in research, including psychosocial development (self-esteem, autonomy, attachment, and identity formation). Reliable and consistent survey tools are essential to understanding developmental trends. This study focused on creating surveys that could be comprehended by all adolescents, no matter if they experience IDD or not. Findings from this study suggested that there are more similarities than difference across areas of psychosocial development among adolescents with IDD as well as with their typically developing peers. These findings can help researchers more accurately assess psychosocial development for more adolescents, including those experiencing IDD.

Highly Variable Rainfall-Runoff Patterns Across Burned Mountainous Watersheds In The Colorado River Headwaters, Haley Anne Canham

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Wildfires can contribute to enhanced flooding, erosion, debris flows, sediment transport, and water quality changes that impact downstream infrastructure, water users, and aquatic habitat. With increasing wildfire risk in the western U.S. due to a changing climate, understanding post-wildfire rainfall-runoff patterns and controls is critical for continued water resources security. To improve understanding of post-wildfire rainfall-runoff patterns and controls, we developed a transparent, repeatable analysis framework to collect precipitation and streamflow data, identify paired rainfall-runoff events, and analyze these events to evaluate post-wildfire rainfall-runoff patterns and controls. To automate the rainfall-runoff event identification, the Rainfall-Runoff Event Detection and Identification (RREDI) …

Impacts Of The Changing Pacific On North American Drought, Atmospheric Rivers, And Explosive Cyclones, Jacob Stuivenvolt-Allen

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The impacts of specific weather events can vary greatly from year to year. Much of these impacts depend heavily on the frequency of impactful weather which is constrained by the state of the climate system each year. This research focuses largely on the impacts that climate oscillations from year-to-year or even from decade-to-decade have on the frequency of impactful weather. There are numerous examples of impactful weather that impact North America, but this work focuses on drought in the western United States, atmospheric rivers in Northern California and rapidly developing winter storms along the east coast. While seemingly disparate events, …

Spacecraft Formation Flying Control Switching Surface Based On Relative Orbital Elements, Tyson K. Smith, John Akagi, Greg Droge

Space Dynamics Laboratory Publications

The development of a switching surface constraint based on the D’Amico relative orbital elements (ROE) is presented in this paper. Relative orbital elements give a more intuitive understanding of how the relative motion of a cluster of satellites changes with time and allows the control algorithm to take advantage of the natural dynamic motion. This work models each vehicle using a model predictive control (MPC) approach, based on the Hill-Clohessey-Whiltshire (HCW) equations, to plan maneuvers which are simulated using a high-fidelity motion model. An ROE based convex polytope switching surface is added to the MPC formulation to force the states …

Recognizing And Reducing Ambiguity In Mathematics Curriculum And Relations Of Θ-Functions In Genus One And Two: A Geometric Perspective, Shantel Spatig

All Graduate Plan B and other Reports, Spring 1920 to Spring 2023

Anxiety and mathematics come hand in hand for many individuals. This is due, in
part, to the fact that the only experience they have with mathematics is what some
mathematics educators refer to as "schoolmath," which uses a somewhat different
language than real mathematics. The language of schoolmath can cause individu-
als to have confusion and develop misconceptions related to several mathematical
concepts. One such concept is a fraction. In chapter one of this report, one possible
reason for this is discussed and a possible solution is purposed.
In chapter three of this report, genus-two curves admitting an elliptic involution …

Investigating Cause-Specific Mortality Of Sheep To Determine The Impacts Of Carnivores On Domestic Livestock, Nathan Jacob Floyd

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Livestock and carnivores interact in ways that are considered conflict throughout the world. In the western United States, livestock are often grazed on public lands in close proximity to predators in their natural habitat, and can be killed as prey. Livestock losses to predators can threaten rancher’s livelihoods. Sheep and lambs are especially vulnerable to predators due to their small size and lack of defensive abilities. To reduce the impacts that predators have on livestock, it is important for ranchers and wildlife biologists to have an accurate understanding of how many livestock die and are killed by predators when grazing …

High School Biology Teachers' Integration Of Argumention In The Context Of Disciplinary Literacy Coaching, Ashley Strong

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Scientific argumentation is a core scientific practice. Although scientific argumentation has been linked to increased learning of scientific content, improved reading, writing, and critical thinking, traditional science classrooms have not included scientific argumentation. Teachers often have little experience learning or teaching science through argumentation and need support to integrate this complex practice of science into their classrooms. This study compared four high school biology teachers’ instruction of scientific argumentation as they worked with a literacy coach. Data were collected through interviews, audio recordings of classroom instruction and literacy coaching sessions, and artifacts. After analyzing the data, several key findings stood …

Organizational Culture And Communication Competence Workshop: Masters Plan B, Travis Bergon

All Graduate Plan B and other Reports, Spring 1920 to Spring 2023

This project began as an attempt to understand how events, such as the “Great Resignation” (i.e., an unprecedented mass exit of employees from the U.S. workforce), have impacted the way in which organizations are attempting to mitigate employee turnover. In addition, this project examined what role managers might play in promoting a positive organizational culture. A review of literature identified Schein’s (1990) model of organizational culture and Spitzberg and Cupach’s (1984) conceptualization of communication competence as useful frameworks for helping managers understand and promote positive organizational culture and employee mental health and well-being. In addition, the review of literature pointed …

Power And Communication: A Literature Review And Course Proposal, Cody Clayton

All Graduate Plan B and other Reports, Spring 1920 to Spring 2023

This paper overviews my final master’s degree project. In this project, I researched the intersection of power and communication. Using academic articles, I reviewed best practices regarding power in the classroom. In addition, I found articles that discussed power and communication within organizations. Using these two bodies of research, I wrote a literature review focused on power bases and power distances. These two specific forms of power were chosen because they each have a different focus, but they can both be applied to teaching practices and organizations. I was then able to design a course to teach these concepts by …
