Teaching The Engineering Design Process To High School Students By Implementing A Non-Traditional Engineering Capstone Course, Joseph Woodard

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

This plan B project is to showcase the implementation of an engineering design capstone course at a remote, rural public high school, in a non-traditional (after-school) format with a small group of students. The project documents successful strategies along with challenges that were learned from such an implementation of this course. Three high school students were supported in learning to solve an extended design challenge, in this case creating an augmented reality (AR) sandbox. The project shows how a capstone course can be utilized in teaching students to solve complex, ill-structured problems.

In this project, a manuscript was prepared for …

Straight Men Come Out: Queer Eye And The Path To A More Mindful Masculinity, Eli M. Roush

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

My thesis explores the culture surrounding the 2018 reboot of Queer Eye for the Straight Guy in relation to contemporary arguments in masculinity studies about the costs of hegemonic masculinity, performance, and identity. This paper examines how Queer Eye carefully creates space where heteronormative men can safely express emotional vulnerability and embody a more functional masculinity that expands beyond the bounds of hegemonic performance. The bulk of the analysis involves close readings of specific episodes and scenes from Queer Eye that introduce and examine the strategies the Fab Five use to redefine their subject's engagement with masculinity, explore the effectiveness …

Mass Shootings And The Performance Of Tourism Stocks, Marshall Deem

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

This study investigates the effects of mass shooting events on the performance of the tourism industry within the United States. The results of the study show that outside of the market-wide returns, the performance of tourism stocks is negatively impacted after a large-scale mass shooting event. Furthermore, when separating extreme outliers in the data such as the Las Vegas Mandalay Bay shooting, the results of the study find that tourism stocks surrounding other large-scale mass shootings are significantly negative. Overall, the results of the study demonstrate a negative response in the tourism industry to large-scale mass shootings.

Youth In World War Ii, Alyson Griggs

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

This thesis project consists of two focuses. The first part focuses on the experiences of Japanese American adolescents who were interned with their parents at the Central Utah Relocation Center during World War II. Although these students were born in the United States and therefore U.S. citizens, they were considered "Japanese" by the U.S. government and many of its citizens. When the U.S. government forcibly removed Japanese American youth and their families from the West Coast, this heavily affected Japanese American youth's perceptions of themselves and the country of their birth. This portion of the project includes a digital exhibit, …

Precision Pointing Considerations For Long-Distance Free-Space Optical Communications, John Thomas Beasley, Thomas Benjamin Walsh, Eric Glenn Forstner

Small Satellite Conference

Present and future demand for global, low-latency telecommunications gives rise to several proposed constellations of satellites in Low Earth Orbit that feature high-bandwidth optical network links between spacecraft.

Free-space optical communication between satellites on separate orbital planes is a non-trivial endeavor. Over long distances, the budget for pointing error is very restricted. To illustrate the scales involved, this paper begins with a quantitative examination of angular inter-satellite vectors. This establishes context for the subsequent presentation of relevant design, integration, and on-orbit considerations that affect the ultimate performance of extremely precise pointing and tracking systems.

Coarse pointing precision plays a substantial …

Genomic Insights Into Speciation History And Local Adaptation Of An Alpine Aspen In The Qinghai–Tibet Plateau And Adjacent Highlands, Jia-Lang Li, Lin-Ling Zhong, Jing Wang, Tao Ma, Kang-Shan Mao, Lei Zhang

Aspen Bibliography

Natural selection serves as an important agent to drive and maintain interspecific divergence. Populus rotundifolia Griff. is an alpine aspen species that mainly occurs in the Qinghai–Tibet Plateau (QTP) and adjacent highlands, whereas its sister species, P. davidiana Dode, is distributed across southwest and central to northeast China in much lower altitude regions. In this study, we collected genome resequencing data of 53 P. rotundifolia and 42 P. davidiana individuals across their natural distribution regions. Our population genomic data suggest that the two species are well delimitated in the allopatric regions, but with hybrid zones in their adjacent region in …

Nonhost disease resistance is the most common type of plant defense mechanism against potential pathogens. In this study, the metabolic enzyme formate dehydrogenase (FDH1) was identified to be involved in nonhost disease resistance in Nicotiana benthamiana and Arabidopsis thaliana. In Arabidopsis, AtFDH1 was highly upregulated in response to both host and nonhost bacterial pathogens. Arabidopsis Atfdh1 mutants were compromised in nonhost resistance, basal resistance, and gene-for-gene resistance. The expression patterns of salicylic acid (SA) and jasmonic acid (JA) marker genes after pathogen infections in Atfdh1 mutant indicated that SA is most likely involved in the FDH1-mediated plant defense response to …

Animal, Dairy, and Veterinary Science Faculty Publications

Placenta-derived extracellular vesicles (EVs) are involved in communication between the placenta and maternal immune cells possibly leading to a modulation of maternal T-cell signaling components. The ability to identify EVs in maternal blood may lead to the development of diagnostic and treatment tools for pregnancy complications. The objective of this work was to differentiate EVs from bovine placenta (trophoblast) and peripheral blood mononuclear cells (PBMC) by a label-free, non-invasive Raman spectroscopy technique. Extracellular vesicles were isolated by ultracentrifugation. Dynamic light scattering (DLS) and scanning electron microscopy (SEM) were applied to verify the presence and the size distribution of EVs. Raman …

Investigating The Direct And Indirect Effects Of Forest Fragmentation On Plant Functional Diversity, Jenny Zambrano, Norbert J. Cordeiro, Carol Garzon-Lopez, Lauren Yeager, Claire Fortunel, Henry J. Ndangalasi, Noelle G. Beckman

Biology Faculty Publications

Ongoing habitat loss and fragmentation alter the functional diversity of forests. Generalising the magnitude of change in functional diversity of fragmented landscapes and its drivers is challenging because of the multiple scales at which landscape fragmentation takes place. Here we propose a multi-scale approach to determine whether fragmentation processes at the local and landscape scales are reducing functional diversity of trees in the East Usambara Mountains, Tanzania. We employ a structural equation modelling approach using five key plant traits (seed length, dispersal mode, shade tolerance, maximum tree height, and wood density) to better understand the functional responses of trees to …
