Strangers To The Algorithm: The Effects Of Algorithmic Decision-Making In Removal Proceedings On Due Process Rights, Otoniel Ramos

Undergraduate Research Symposium Podium Presentations

This paper investigates the impact of algorithmic decision-making tools on due process rights, particularly within immigration removal proceedings. Deviating from prior studies, which primarily focused on various measures of fairness or the long-term racial stratification as a consequence of these tools, this research emphasizes the implications for due process—a fundamental legal principle enshrined in the U.S. Constitution. By examining ICE's use of these tools between July 2012 (when they were adopted) and October 2016, the study reveals the ways algorithmic input may inadvertently erode principles of procedural justice, especially adjudicatorial independence, in a setting where the rights of non-citizens are …

Improving Healthcare Utilization Models And Uncovering Health Behavior Patterns In Asian Americans Through Data Disaggregation, Luke Cho

Undergraduate Research Symposium Podium Presentations

Although Asian Americans are made up of 20+ distinct ethnicities with unique health outcomes, previous healthcare research has treated them as a monolithic group, covering up many important disparities in health outcomes and healthcare utilization patterns. This study examines how disaggregating Asian American health data by ethnicity improves models analyzing healthcare utilization patterns, focusing on routine physicals, dental checkups, alternative medicine consultations, and preference for ethnic concordance.

Using data from the 2015 Asian American Quality of Life survey (2,609 adults in Austin, Texas), binomial generalized linear models (GLMs) analyzed the impact of income, age, gender, insurance status, and ethnicity on …

Exploring Modality Differences In Recognition Memory: Repetition Effects On Recollection And Familiarity, Ivanesa Velikova, Kevin Mohawk, Colleen Parks

Undergraduate Research Symposium Posters

Research has shown that memory for visual objects tends to be superior compared to memory for auditory objects. The present study aimed to investigate the underlying mechanisms of why recognition memory tends to be better for visual information. Recognition memory relies on two processes, recollection and familiarity. Recollection involves retrieving contextual details of a memory while familiarity is simply a feeling that something has been encountered before. We investigated recollection and familiarity in the two modalities by having participants lean a list of auditory objects (e.g., dog barking) and visual objects (e.g., picture of a lion) under full attention (FA) …

The Impact Of Intimate Partner Violence On Young Mother's Mental Health, Claudia Chavez, Clariana Vitória Ramos De Oliveira

The Effect Of Encoding Strategies On Recognition Memory, Camila Schettini, Cole Kaneshiro, Kevin Mohawk, Colleen Parks

Undergraduate Research Symposium Posters

Successful memory decisions require distinguishing between true and false memories. VariouS strategies can be used to avoid false memories such as the Recall-To-Reject (R-R) strategy and the Distinctiveness Heuristic (DH). R-R involves rejecting false information by recalling correct information (I know this person is not Bob, because Bob has brown hair); while DH involves the rejection of false information due to failure to recollect expected information (I know I never met this person because I would remember if I had). The purpose of this study is to examine how these strategies affect recognition memory. In the present study participants were …

Comparing Forgetting Rates Between Item And Relational Memories, Lex De Asis, Rhiannon N. Soriano Smith, Colleen M. Parks

Undergraduate Research Symposium Posters

Forgetting is an everyday occurrence where an idea that could be recalled successfully is no longer able to be retrieved (Tulving, 1974). Multiple theories suggest how forgetting occurs, such as the decay theory, which suggests that memories are gradually forgotten over time, and the interference theory, in which forgetting occurs because of competing information. Additionally, there are two newer theories which both predict that item representations should be forgotten because of interference and mnemonic discrimination should be forgotten due to decay: the memory system-dependent forgetting hypothesis (Hardt, Nader, & Nadel, 2013), and the representation theory of forgetting (Sadeh et al., …

A Simple And Low-Cost Method For Generating Short Laser Pulses, Daniel Fisher

Undergraduate Research Symposium Posters

A simple, portable method is described and demonstrated for generating short optical pulses (~ 1 μsec) from a continuous wave (CW) source using a rotating pinhole. A CW 633nm HeNe beam was focused onto a 225 μm diameter stainless steel pinhole, which was rotated up to 1000 Hz using an optical chopper wheel. The pulsed light was then focused onto a silicon photodetector and read by an oscilloscope.

Undergraduate Research Symposium Posters

During deep space exploration, astronauts depend on mission-essential performance in Dual Cognitive Motor Tasks (DCMT), such as receiving information from ground control to assemble and configure wires during a spacewalk. DCMT relies upon processing cognitive and motor information simultaneously. Previous research on rodent models has shown various impairments in cognition and motor function in separate tasks after exposure to deep space radiation and sleep fragmentation (SF). However, an assessment of DCMT performance in rodents has not been established. Rats and humans use similar hand-over-hand movements to pull a string, and task demands may be varied to assess cognition and motor …

Impact Of Young Biocrust On Dryland Surface Albedo, Rhynhardt Mudde, Rebekah Magness, Raul Roman, Nicole Pietrasiak

Undergraduate Research Symposium Posters

More than 40% of the Earth’s surface is covered by drylands. Due to limited availability of water, less surface area is covered by vascular plants. Instead, this space is occupied by microbial communities that exist in close contact with mineral soil, creating a living aggregate on the upper soil layer and are known collectively as biological soil crusts or “biocrusts”. Biocrusts play a vital role in ecosystem functioning in drylands specifically through their influence on hydrological processes (e.g., water retention, infiltration). However, the impact of biocrusts on evaporation is not well understood. Biocrusts have been reported to either increase or …

The Characterization Of Cooperative String-Pullung Behavior In Rats After Exposure To Space Flight Stressors, Teresa L. Garcia, Nuhamine A. Moges, Sierra Ordonez, Nicole M. Attallah, D. H. Rodgers, A. Adhikari, K. D. Omengan, D. Lloyd, S. L. Gleed, A. A. Blackwell

Undergraduate Research Symposium Posters

Astronauts work cooperatively to complete tasks on missions through deep space where they will experience stressors, including radiation and sleep fragmentation, that may impair performance. Animals work together to achieve a common goal during cooperative tasks using string-pulling behaviors. While string-pulling behavior has revealed deficits in rat sensorimotor function after exposure to space flight stressors, it has yet to be determined if rats will engage in cooperative string-pulling or if these stressors will influence cooperation. Thus, to explore how space flight stressors impact cooperative behavior, female Wistar rats were exposed to either sham (n = 8) or 10 centi-grays of …

Undergraduate Research Symposium Posters

In the United States, one in three adults has pre-diabetes, and 80% are unaware that they are at risk of developing type-2 diabetes (T2D). Elevated blood glucose levels are associated with an increased risk of heart disease, obesity, dyslipidemia, and hypertension. African-American and Hispanic individuals are disproportionately affected by pre-diabetes and its complications, such as arterial stiffness and obesity, compared to Caucasians. Approximately 70% of those with pre-diabetes may develop T2D, therefore it is crucial to find effective ways to manage and reverse these conditions. Potatoes, which contain a good source of resistant starch, potassium, and other beneficial nutrients, might …

Examining Emotion And Ease Of Recall For Life Story Memories In Young Adults, Roxanna E. Chavez, Erin L. Murphy, David E. Copeland

Undergraduate Research Symposium Posters

Life stories are narratives that use autobiographical memories to shape personal identity. This study investigated how emotional valence and ease of recall may change over time. Participants were asked to recall ten life story memories in two interviews held three weeks apart. Participants provided ratings of emotional valence and ease of recall for each memory. A significant difference was found in emotional valence between Session 1 (M = 3.159, SD = .772) and Session 2 (M = 2.905, SD = .788), t(68) = 2.734, p < .01, with Session 1 memories rated as significantly more negative (M = 1.812, SD = 1.427) than those in Session 2 (M = 1.275, SD = 1.316), t(68) = 3.232, p < .01. Furthermore, negative memories were more frequent in the last five Session 1 memories (M = 0.986, SD = 0.866) than in all of Session 2 memories (First Five: M = 0.652, SD = .783; Last Five: M = 0.623, SD = .892), F(3, 204) = 3.663, p < .05. For ease of recall, the first five memories in both sessions (Session 1: M = 5.684, SD = 0.806; Session 2: M = 5.612, SD = 0.963) were significantly easier to recall than the last five in both sessions (Session 1: M = .214, SD = 1.128; Session 2: M = 5.136, SD = 1.080), F(2.498, 169.864) = 7.369, p < .001. Overall, these findings suggest participants recalled more accessible memories first, with negative memories being harder to retrieve as sessions progressed.

The Relationship Between Gender And Experienes Of Weight Stigma From Healthcare Providers, Isabella J. Aceituno, Shannon Sagert

Undergraduate Research Symposium Posters

Healthcare providers are a common source of weight stigma, which is associated with lower physician trust, poorer patient outcomes, and the avoidance of healthcare services. Currently, there is a lack of consensus in research on whether women and men are equally likely to experience weight stigma from healthcare providers. The present study examined whether gender differences exist in weight stigma received from healthcare providers in childhood or adulthood, comfort seeking medical care, and healthcare avoidance. Adult participants (N = 196) reported the frequency at which they experienced stigmatizing experiences in healthcare environments in the past 12 months and during childhood …

"Screen Time" And The Perception Of It Among Different Social Classes, Jasmine Ayon

Undergraduate Research Symposium Posters

“Screen Time” and the subsequent demonization of it is a phenomenon that is not as analyzed through a social and comparative lens as much as psychological and health ones. To address this gap in research, we performed a content analysis on articles concerning families and “screen time” use that were published on two well-known parenting websites SheKnows and Parents.com from 2019 - 2022 (n = 220). In this paper, we address how these articles talk about screen time use among different social classes. In our analysis, we found what appears to be a double standard in the way screen time …

Effects Of Fire Temperatures On Mojave Desert Native And Nonnative Seeds, Sophia Lorenzana, Lindsay Chiquoine

Undergraduate Research Symposium Posters

Large-scale wildfires have been historically rare in hot deserts like the Mojave, largely due to the scarcity or uneven distribution of native plant biomass as fuel. Thus, native plants in these regions are ill-adapted to withstand spreading wildfire, resulting in slow post-fire recovery. Here, I test the hypothesis that nonnative grasses respond better to heat cues than native plant species. Seeds from 3 invasive and 13 native plant species were collected from research sites located in the eastern Mojave Desert, near surrounding Clark County Flood Control District weather stations. Seeds were buried in an artificial substrate mimicking field soil conditions …

Repurposing Non-Toxic And Cost-Effective Organic Ligancds To Enhance The Removal Of Uranium And Thorium From Wastewater, Will Campbell

Undergraduate Research Symposium Posters

Cheap, effective and industrially practical remediation methods for uranium and thorium are of utmost importance. Electrocoagulation is a cheap but only mildly effective method for the remediation of these elements. It was recently shown that chelating ligands enhance this process. Unfortunately, few ligands have been tested for this enhancement. Of these, the most effective, Alizarin Red S, had a 99.2% uranium removal efficiency but was expensive ($3.6 / g), toxic to humans and environmentally harmful. Therefore, ligands that avoid these downsides are needed before any industrial application can occur. Potential ligands were found via exhaustive searches of MilliporeSigma’s database. Over …
