Mapping Of Non-Native Invasive Plant Species Using Remote Sensing And Gis: Assessment Of Human Impact On Kudzu (Pueraria Montana) Spread, Harshitkumar Godhasara
Scholars Week
Remote sensing methods provide tools to identify and map non-native plants. Biophysical characteristics of plants can be utilized to recognize and distinguish non-native invasive plants from other native plant species. Kudzu is an invasive plant, which causes economic loss and decreases biodiversity. Moreover, kudzu doubles emission of nitric oxide and increases ozone pollution. The impact of human activities on the spread of noxious plant species like kudzu can be assessed utilizing remote sensing and geographic information systems (GIS) tools. Kudzu spread in the USA was mapped using in situ data including the actual coordinates of kudzu sites. Geographic distribution of …
Pilot Study Exploring The Impact That Laboratory Instruction Has On A Student's Stem Professional Identity , Datiel Dayani, Dr. Michelle Head
Pilot Study Exploring The Impact That Laboratory Instruction Has On A Student's Stem Professional Identity , Datiel Dayani, Dr. Michelle Head
Symposium of Student Scholars
STEM professional identity serves as one lens through which researchers have used to study factors that influence achievement in chemistry courses and persistence in a STEM major. The literature has proposed that the high attrition rate among STEM majors may result from the student’s evolving professional identity, motivational factors, and how they correlate a STEM career to their future aspirations. There is limited insight into how laboratory classes and teaching practices affect a student’s professional identity development. To investigate this, this study employed James Marcia’s identity development theory to understand the relationship between a student's identity status and their perception …
Nudging Students To Use Stronger Passwords: A Test Of Big Five Personality-Based Messages, Shelia Kennison, Eric Chan-Tin
Nudging Students To Use Stronger Passwords: A Test Of Big Five Personality-Based Messages, Shelia Kennison, Eric Chan-Tin
Computer Science: Faculty Publications and Other Works
Cybersecurity breaches can occur when one uses an easily hacked password. Prior research has investigated 1) possible steps to encourage users to use strong passwords and 2) how personality is related to users using strong passwords.
We investigated whether personality-based nudging messages based on Big Five traits could nudge people to create stronger passwords (c.f., Jones et al., 2021). We also examined how personal characteristics, such as gender, age, personality traits, password knowledge, attitudes, and behavior, and need for cognition, were related to password strength.
We tested the hypothesis that passwords created following messages matching participants’ personality would be stronger …
Tweets R Us: Predicting Personality From Language And Emoji Use On Twitter, Maxwell Meckling, Sarah Shoup, D. E. Chan-Tin, Shelia Kennison
Tweets R Us: Predicting Personality From Language And Emoji Use On Twitter, Maxwell Meckling, Sarah Shoup, D. E. Chan-Tin, Shelia Kennison
Computer Science: Faculty Publications and Other Works
The research investigated the suggestion from prior research that language and emojis use on Twitter and other social media platforms can predict users’ personality and gender (Adali et al., 2014; Golbeck et al., 2011; Li et al., 2019; Moreno et al., 2019; Raess, 2018). Some studies have also analyzed Twitter language to identify individuals with specific health conditions (e.g., alcohol recovery, Golbeck, 2012; sleep problems, Suarez et al., 2018).
If strategies to predict Twitter users’ characteristics prove to be successful, future efforts to direct persuasive messages related to recommended practices in public health and/or cybersecurity will be possible. Commercial applications …

Speed And Accuracy For Partial Differential Equation Solvers, Aidan Grasby
Speed And Accuracy For Partial Differential Equation Solvers, Aidan Grasby
Undergraduate Student Research Internships Conference
This Research project consisted of testing multiple software used to solve partial differential equations to determine the fastest solver while not compromising other aspects such as accuracy. The larger project involved using electrodes and electric fields to treat brain tumours. An optimization program is required to determine electrode placement and this program must solve partial differential equations to determine the electric field for each electrode configuration. This optimization step is extremely slow so it is critical a faster partial differential equation solver is found. Therefore, I tested various software to determine the fastest solver that could then be linked with …

A Paleoseismic Study Of The Twin Lakes Fault, Mount Hood Fault Zone, Oregon, Charlie Carr, Ashley R. Streig
McNair Symposium
Recent geologic mapping on high-resolution topography from lidar has led to the discovery of a zone of active faults on Mount Hood. The Mt. Hood Fault Zone consists of four separate faults, and stretches ~55 km from south to north, and crosses the summit of Mount Hood. The focus of this study is the northern section of Twin Lakes Fault, which lies directly south of Mount Hood and adjacent to OR35 and the White River. Lidar topography reveals the west side down normal displacement on the Twin Lakes fault. The highest tectonic seismicity rates in the Mount Hood area occur …

54fe(D,P)55fe Single Neutron Transfer Presentation, Matthew Quirin, Raymond Saunders
Physics and Astronomy Presentations
During our summer research at the John D Fox Laboratory, we used the 9 MV Tandem van de Graaff accelerator and the Super Enge Split-Pole Spectrograph to make measurements of the neutron transfer reaction 54Fe(d,p) 55Fe to observe and explore excited states of 55Fe and shell structure beyond the magic number N=28. We have created momentum spectra and angular distribution plots of the protons from the reaction which will be analyzed to determine the angular momentum values of states and single-neutron energies in 55Fe in an effort to better understand nuclear structure.
Analysis Of Botulinum Toxin A And Interacting Proteins In Skeletal Muscle Cells: An Investigation Into The Mechanisms Of Botulinum Toxin A As A Treatment For Chronic Exertional Compartment Syndrome, Lauren Kee
Pence-Boyce STEM Student Scholarship
Background: Chronic exertional compartment syndrome (CECS) is a condition in which muscle tissue expands against the surrounding fascia during activity and is compressed along with the nerves and blood vessels within the muscle compartment, leading to abnormally high intracompartmental pressure (ICP) and debilitating pain. Treatment typically includes fasciotomy, which results in significant levels of CECS recurrence; however, botulinum toxin A (BoNT-A) injection has recently been seen to decrease both ICP and pain through an unknown mechanism with little to no recurrence.
Methods: In this study, cyclooxygenase-1 (COX-1), cyclooxygenase-2 (COX-2), prostaglandin E2 receptor 4 (EP4), endothelial nitric oxide synthase (eNOS), …

Downscaling Methodology For Satellite Land Surface Temperatures Over Urban Environments, Naved Khan, Ruben Vecino
Publications and Research
The objective of this study is to develop high spatial and temporal resolution Land Surface Temperature (LST) data using a combination of Landsat 8, infrared satellite sensors such as the Moderate Resolution Imaging Spectroradiometer (MODIS), and the Geostationary Operational Environmental Satellite-R Series (GOES-16). The Landsat 8 Thermal Infrared Sensor (TIRS) provides higher spatial resolution (30 m) estimates of skin temperature every 16 days. MODIS makes daytime and nighttime observations of the Earth’s thermal emission at a coarser spatial resolution (1000 m), while GOES-16, which has lower spatial resolution (2 km), measures the skin temperature at a much higher temporal resolution …

How Risk-Related Statistics, As Reported In News And Social Media, Are Linked To The Use Of The Public Transit System, Prashiddhi Pokhrel
Thinking Matters Symposium
Due to the pandemic, people have started relying more on televisions, news, social media, and other news outlets for guidance. Moreover, with the increasing amount of news, data, and information there is also an increase in the amount of misleading statistics. People’s opinions and decisions significantly depend on the data, statistics, and information that they are exposed to, as well as their sources. For this project, we want to look at how information and its sources are affecting the decision made by the general public for the usage of the Portland Transit System. It is very important to know why …
