David Lum Interview
No full textMr. David Lum, Linfield class of 1958, is a former PE teacher and founder/owner of Lum’s Auto Center, which has two locations in Oregon and one in Washington.
This interview takes place at the Linfield University McMinnville campus, conducted by Linfield archivist Rich Schmidt, on January 24, 2022.
In this interview, Mr. Lum speaks about his early years growing up as a Chinese-American in Astoria, Oregon, especially during the 1930s and 1940s. He also speaks about the influences that led him to Linfield, people he remembers from his time there, and his early career post-graduation. Mr. Lum also discusses his career in car sales and important take-aways from his experiences as he reflects on his life
Impacts of R&D Funding and Climate Change on Agricultural Output Within the U.S.
No full textIn recent years, record amounts of natural disasters have occurred, decreasing profitability of farming operations and jeopardizing sufficiency of international food supplies. We believe climate change to be at the forefront of these issues. With rapid changes in climate occurring, one would expect public sector research and development funding to increase, in attempt to develop new technologies that could compensate for productivity losses. The research examines the relationship between public research and development funding and aggregate agricultural output in the United States. Through extensive data analysis, this study has found that research and development funding has a positive relationship with aggregate output, whereas climate change indicators have a negative relationship with aggregate agricultural output. Regressions were designed to explain aggregate agricultural output as a function of climate change indicators, public sector research and development funding, fertilizer use, agricultural total factor productivity, labor inputs, and more. With uncertainty ahead in global food supply, increasing population, and changing environment, the findings of this study stress the importance of increased investment in agriculture within the United States and throughout the world
Is Retinoid X receptor alpha a mtDNA transcription factor?
Get PDFMitochondria are important organelles in eukaryotic cells due to their role in metabolism. They also have their own genome (mtDNA) which encodes many of the protein subunits within the oxidative phosphorylation (OXPHOS) pathway. The remaining protein subunits are encoded in the nuclear genome, translated in the cytosol, and imported into mitochondria. Transcriptional coordination between these two genomes to produce functional OXPHOS complexes is critical to maintaining cellular homeostasis. A major control point is transcription, this process requires regulatory proteins that determine the expression of these genes. Retinoid X receptor alpha (RXRα) is a protein that has many functions in human cells and is a ligand activated nuclear receptor. It can also translocate to the mitochondria where its purpose is unknown. The goal of this project is to determine the role of RxRα as a mitochondrial transcription factor. We have expressed and purified the RXRα protein, and then also assessed its DNA binding affinity with various mtDNA sequences. We concluded RXRα binds as a dimer with space between the binding sites. Our aim is to investigate RxRα binding the mtDNA using atomic force microscopy (AFM). In doing so we will better understand the mechanisms that are involved in mtDNA transcription. If RxRα is a transcription factor, that is another protein that we can regulate to increase or decrease transcription. Being able to increase or decrease transcription in mitochondria is important as mitochondrial dysfunction causes a wide array of diseases and plays a part in aging
Did She Ask for It?: A Content Analysis of Sexual Assault Myths in Popular Television
No full textResearch on media effects indicates that viewers develop sexual attitudes and beliefs consistent with what they see on the screen. The goal of this research was to investigate the accuracy of sexual assault portrayals in media. Popular television shows among college students were coded for the presence of common rape and perpetrator myths about sexual assault. A team of six undergraduate research assistants coded 48 episodes of 26 popular shows. This poster will highlight themes that were found in this content analysis

Characterization of Electronic Behavior within a 2D FET using KPFM
No full textDeveloping a further understanding of the electronic behavior within 2D devices is a crucial step before implementing their wider use in technology. A 2D Field Effect Transistor (FET) utilizes biasing a graphene back gate to shift the chemical potential of the WSe2 semiconductor above it. In this experiment Kelvin Probe Force Microscopy (KPFM), an indirect work function measurement technique, has been used to generate potential spatial maps of the 2D FET at differing back gate biases. KPFM results are reaffirmed by expected electronic behavior in areas of the h-BN insulative component and the graphene conductive contact component. The measured electrostatic potential of WSe2 coincides with the electronic behavior of ambipolar semiconductors. The relative chemical potential of the WSe2 sample was extracted and an estimated bandgap of 1.26 ±.063 eV was derived, falling outside of reported results
