Utilizing Additive Manufacturing Of Semi-Crystalline Thermoplastics And Topology Optimized Generative Designs For Complex Small Satellite Bus Geometries, William Hunter Bradford, Aidan Delliponti, Ryan Formel

Small Satellite Conference

Small satellite buses have traditionally been manufactured through subtractive means and ultimately limiting capability in feature, form, and an inability to alter the volumetric density of the material. However, emergent additive manufacturing methods that utilize Fused Deposition Modeling (FDM) integrated with soluble support material allow us to print synthetic thermoplastics, such as Polyetheretherketone (PEEK). Consequently, the number of structural parts and hardware components is reduced, along with the cost. Structural strength and dimensional stability of PEEK are comparable to traditional aluminum alloys in the construction of most satellite components. Additive manufacturing further allows the implementation of topology optimization algorithms to …

Evaluating Network Performance Of Containerized Test Framework For Distributed Space Systems, Walter Vaughan, Alan George, Brian Kempa, Daniel Cellucci, Nicholas Cramer

Small Satellite Conference

Distributed space systems are a mission architecture consisting of multiple spacecraft as a cohesive system which provide multipoint sampling, increased mission coverage, or improved sample resolution, while reducing mission risk through redundancy. To fully realize the potential of these systems, eventually scaling to hundreds or thousands of spacecraft, distributed space systems need to be operated as a single entity, which will enable a variety of novel scientific space missions. The Distributed Spacecraft Autonomy (DSA) project is a software project which aims to mature the technology needed for those systems, namely autonomous decision-making and swarm networking. The DSA project leverages a …

Lunarwsn Node - A Wireless Sensor Network Node Designed For In-Situ Lunar Water Ice Detection, Fangzheng Liu, Ariel Ekblaw, Joseph Paradiso

Small Satellite Conference

In this paper, we present a fully functional cubic sensor node prototype designed to be ballistically deployed from a rover or lander to regions of interest that might be unsafe or impractical for rovers or landers to reach. Unlike helicopters or drones, this system can be deployed in airless environments. Crucially, the nodes are equipped with wireless ranging and wireless communications capabilities, such that each node can be localized by leveraging wireless ranging with triangulation, and a cluster of deployed nodes form an expandable WSN (Wireless Sensor Network), that we term LunarWSN. The hardware redundancy of the network can reduce …

Small Satellite Conference

This paper analyzes the various problems high school CubeSat organizations face, as well as their potential solutions. We conducted a case study of various high school CubeSat organizations from around the United States, interviewing them about their mission goals, organizational structure, funding sources, and other relevant information. We found that the three most common significant problems faced by these CubeSat teams were a lack of student training, turnover, and time commitment constraints. By comparison, a lack of funding and access to mentors were not expressed as the most significant problems for any of the groups. Teams shared their solution to …

Settler-On-Settler Violence: Ritual Protocols In Youtube Street Fight Videos - Paper 1, Kelly Menzel, Tyson Yunkaporta

Journal of Indigenous Research

This is part one of a series of two papers exploring a project that was conducted by two Australian Aboriginal researchers, one male and one female, and might be described as ‘reverse anthropology’, in the same way that people sometimes refer to positive discrimination as ‘reverse racism’. But we would just call it anthropology; a tidal river is still a river when it flows back the other way. The project could hardly be acknowledged as anthropology though, as it was based on Indigenous methods of inquiry that do not yet belong to a formal discipline. Initially the goal was to …

Spectral Ocean Color (Spoc): Lessons Learned From The University Of Georgia Small Satellite Research Laboratory's First Satellite, Sydney Whilden, Deepak Mishra, David L. Cotten, Nicholas Neel

Small Satellite Conference

In October 2020, the University of Georgia Small Satellite Research Laboratory launched its first CubeSat, a 3U Earth-observation mission designed to collect multispectral data from Georgia’s coastal environments for UGA’s Center for Geospatial Research to make recommendations on environmental conservation, care, and use. SPOC successfully detumbled, but after approximately a month in orbit, a coronal mass ejection (we speculate) caused us to lose contact. Despite our disappointment at the loss of SPOC, we are leveraging the lessons learned for our upcoming missions. These lessons can be categorized in four principal areas: software (flight and payload), mission operations, testing, and educational …

Aspen seedlings for boreal mine reclamation

Bradley Pinno

Trembling aspen is a major component of the forests in Alberta. Aspen is an early successional species which occurs in both pure and mixed stands. It also provides the timber for pulp mills and oriented strand board mills with a harvest rate of nearly 12M m³ (5.08 BBF) of aspen timber annually in Alberta. Aspen normally regenerates vigorously after disturbance from root suckers in the range of 10,000–100,000 stems per hectare. However, after industrial disturbances such as mining or the creation of well sites where the soil has been removed, root …

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

This dissertation reports on research conducted to better understand how college student writers learned to work against their own biases as they researched and wrote arguments. I conducted a review of former studies to design a curriculum that would help students avoid bias and increase their ability to write arguments tailored to specific readers in ways that accomplish their goals. This review also informed the kinds of data to be collected and analyzed in order to accomplish the research goal, which was to understand whether and how each of seven students enrolled in a composition course reduced their biases. I …

Executive Orders On A Political Timeline: Examination Of Executive Orders In The Supreme Court And Stephen Skowronek's Theory Of Presidential Leadership, Alisha Rachele Urrutia

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The research performed here applies a theoretical model of the presidency by Stephen Skowronek that spans all of American history to the number of executive orders issued per president and the number of these orders argued before the Supreme Court per president. I hypothesized that presidents who have the fewest political resources available to them (disjunctive presidents) would issue the most executive orders, and presidents who transform the face of American government and politics (reconstructionists) would face the most Supreme Court cases dealing with executive orders. I created two datasets for this research and used descriptive statistics to evaluate these …

Reversing The Gaze: Using Indigenous And Western Worldviews To Compare Coverage Of Climate Change And Indigenous Peoples In The News Media, Gina Mccrackin

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The news media acts as an important conduit for shaping societal views of the socio-politics of climate change. While climate change will indeed affect everyone, it will not affect everyone equally. Indigenous peoples are among the populations whose well-being is threatened the most by climate change. International scholarship finds it is not uncommon for Indigenous cultures, communities, and perspectives to be underrepresented and misrepresented in Western climate change media. Research also indicates that fair Indigenous representation occurs when Indigenous peoples are the authors of news articles themselves. We evaluated the differences in discussions of climate change and environmental issues …

The Personal Is Still Political: An Analysis Of Jessica Valenti's Contemporary Feminine Style, Michala M. Zilkey

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

In 2016, Jessica Valenti’s memoir, Sex Object, was published. Sex Object describes Valenti’s experiences of sexualization and objectification in a personal and anecdotal format. The feminine style, a rhetorical style that bridges the divide between norms of femininity and expectations of public oration, has been heralded as essential for advancing the feminist movement. This thesis asks the question, to what extent does contemporary feminists’ rhetoric mirror and diverge from earlier iterations of the feminine style? I argue that Valenti’s employs a feminine style that utilizes relational norms and self-disclosure to illustrate the personal as political and the political as …

Who Is More Likely To Be Delinquent In Their Mortgage Payments Among Homeowners? The Role Of Financial Literacy, Ellie Donne Hansen

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Homeownership is a way for families to build wealth and marks status attainment. Despite the many benefits of homeownership, homeowners who are delinquent on their mortgages lose the effective means of wealth accumulation and may trigger the beginning of the foreclosure process. There is evidence that homeowners with appropriate levels of financial literacy have a lower likelihood of mortgage delinquency.

Using data from the 2018 National Financial Capability Study (NFCS), the main purpose of this study was to examine what factors are associated with mortgage delinquency among homeowners. This study also examined to what extent financial literacy plays a role …

Teaching Multicultural Psychology As A Cultural Competence Intervention: An Empirical Evaluation Of Course Components, Elizabeth Tish Hicks

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Previous research has shown that a semester-long multicultural psychology course can effectively increase students’ cultural competence-related attitudes when students complete the class in-person and online. Cultural competence refers to the knowledge, awareness, and skills required to appreciate, recognize, and effectively work with members of other cultural groups. This dissertation examined several components of a multicultural psychology course: ethical grading, skill development, and intergroup contact. The first paper discussed techniques used to minimize grading bias and examined whether cultural competence shifts impacted grading. Students’ cultural competence scores did not relate to or predict their grades in the course, which supported the …

School Resource Officers' Reports Of Training And Perceptions Of High School Students With Disabilities, Kandace T. Jones

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The purpose of this explanatory sequential, mixed methods research study was to identify the perceptions of school resource officers (SROs) regarding high school students with disabilities and their preparedness to work with this population, as a result of their SRO training. This study involved a national quantitative survey of SROs working in public high schools, followed by one-on-one interviews from the same sample to allow for a deeper analysis of the survey results and develop a theory on how training impacts SRO preparedness and their perceptions of high school students with disabilities. The resulting theory ascertained that the presence of …

A Dynamic Relationship With Wilderness: Comparing Day And Multi-Day Visitors' Indicators Of Quality In Wilderness Settings, Caleb Meyer

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The length of stay in wilderness areas is declining and, in many areas, day visitors comprise most of all use. Most prior research exploring this trend took place in the 1990s and few studies of wilderness visitation account for the increase in outdoor recreation participation over the last decade. Lack of understanding surrounding this trend raises questions about managerial and philosophical approaches to the recreation-wilderness relationship. This study explored these topics within visitor use management approaches used by the National Park Service, which manages the proposed Glen Canyon Wilderness, near Escalante, Utah, where this research took place.

Results of this …

Advancing The Cyberinfrastructure For Smart Water Metering And Water Demand Modeling, Nour A. Attallah

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

With rapid growth of urban populations and limited water resources, achieving an appropriate balance between water supply capacity and residential water demand poses a significant challenge to water supplying agencies. With the recent emergence of smart metering technology, where water use can be monitored and recorded at high resolution (e.g., observations of water use every 5 seconds), most existing research has been aimed at providing water managers with detailed information about the water use behavior of their consumers and the performance of water using fixtures. However, replacing existing meters with smart meters is expensive, and effectively using data produced by …

Vietnam Continued: The Battle For American Public Memory In Public School History Textbooks, Donnie Owens

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The question of “how do we actively remember the past?” can perhaps best describe the purpose of public memory studies. Acknowledging this question, I analyze popular public-school textbooks to assess the way in which educational literature constructs the public memory of the Vietnam War. In total, the narratives of the texts construct a public memory of Vietnam as a controversial conflict contained within a decade of American uncertainty. However, these narratives also take care to minimize or leave aside the details of Vietnam’s lasting impact and in favor of reaffirming American exceptionalism. Ultimately, this thesis finds that students who read …

Evaluating Microbial Safety Of Food Products And Processes In Small Scale Food Services, Processors And Manufacturers, Sujan Acharya

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

This study evaluated microbial safety of relatively new and modified food products prepared especially by small-scale foodservice establishments and home producers. In the first part, microbial safety during fermentation at room temperature was evaluated. Chapter 3 monitored Listeria monocytogenes and Escherichia coli O157 survival during Sauerkraut’s natural fermentation. Chapter 4 evaluated the survival of acid-adapted E.coli O157 during kombucha fermentation and in kombucha-fruit blend during refrigeration. During both fermentations, the pathogens were inactivated before the recommended duration of fermentation. However, E.coli O157 introduced after fermentation survived in kombucha-fruit blends during refrigerated storage. The second part (Chapter 5) evaluated the safety …

Emotional Support Animal Partnerships: A Multimethod Investigation, Jillian Ferrell

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Emotional Support Animals (ESAs) are increasing in prevalence and awareness, though not all the publicity and attention have been positive. Many people, including housing officials, persons with disabilities, health professionals, and the general public are confused about the roles and rights of ESAs. Misunderstandings, lack of awareness, and fraud have led to dangerous and inappropriate situations for humans and animals alike despite overwhelming evidence of powerful therapeutic benefits of the human animal bond.

Three studies provide insight into various perspectives involved in ESA partnership experiences and development. Each study provides a theoretical, quantitative, and qualitative approach, respectively, to explore the …

Modeling A Pandemic: Investigating Student Learning About Disease Spread In The Context Of Agent-Based Modeling, Siyu Wu

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The COVID-19 pandemic has highlighted a need for students to learn about public health issues, including the transmission of disease and methods for the prevention of epidemics. This study presents data from a project focused on developing computational microworlds to help middle school students learn about these topics. The microworld is designed to help students model and test their ideas about how a disease spreads through a population and how an epidemic can be prevented. I employed a lab-based case study approach to conduct one-on-one 1.5-hour interviews through Zoom with four middle-school students (ages 12-14). During the interview, the student …

Cuo Nanoparticles Solubility As Influenced By Soil Pore Water, Native Microorganisms, And Wheat Rhizosphere Chemistry In A Sand Matrix, Dakota Sparks

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Nanoparticles (NPs) are particles less than 100 nm (~4 millionths of an inch) in a direction. NPs, due to their small size, are used in a variety of products, such as silver (Ag) NPs as an antimicrobial in clothes. Copper Oxide (CuO) NPs are used in electronics as semiconductors and other fields as antimicrobials and purposefully or accidentally end up in the environment. Copper (Cu) is a necessary nutrient for plants, but at higher amounts is toxic to plants and beneficial soil microbes.

In order to understand how the CuO NPs interacts with plants, wheat seedlings were grown in sand …

Using Cytoplasmic Biopsies To Determine Bovine Oocyte Quality, Madison Lindsey

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Embryos resulting from assisted reproductive technologies, such as in vitro fertilization (IVF) or intracytoplasmic sperm injection (ICSI), develop with lower efficiencies than embryos resulting from their in vivo counterparts. The reasons behind the developmental discrepancies remain largely unknown. Because the egg is the primary determinant of embryo developmental success, it is reasonable to consider inherent egg quality as a possible cause. The hypothesis for this project is that there are distinct mRNA transcript patterns, or molecular “fingerprints,” that distinguish high- versus low-quality eggs developing within the same environment. In this study, a small cytoplasmic biopsy was removed from 40 eggs …

Natural History And Development Of Melittobia Acasta On Megachile Rotunda , Alan R. Anderson

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Alfalfa is one of the most economically important crops in North America. To produce alfalfa seed, a pollinator must release plant reproductive organs by applying pressure to keel petals. The alfalfa leafcutting bee, Megachile rotundata, is the primary commercial pollinator of alfalfa. U.S. bee managers struggle to maintain populations due to many mortality factors. One cause is attack from parasitoid wasps such as Melittobia acasta. Females can lay hundreds of eggs and have multiple generations, which can decimate bee stocks. Chapter Two investigates the life cycle and base temperature that allows development of M. acasta on bee hosts. …

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.

Executive Functioning And Brain Activation In Young Monolingual And Bilingual Children: An Fnirs Study, Matthew L. Cook

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Over the past 40 years, the prevalence of bilingualism in the United States has increased. As bilingualism is increasing, it is important to examine potential benefits or drawbacks that early household bilingual exposure has on child development and how bilingualism may facilitate those benefits or drawbacks. This study included 5 monolingual and 6 bilingual children and compared differences in brain activation location and executive functioning skills. Results from this project show a trend of activation differences where the monolingual children had less activation of the middle area of the prefrontal cortex while there was similar activation in both the left …
