Evaluation Of Sleep Outcomes After Traumatic Brain Injury In Children Using Questionnaires And Actigraphy, Connie Tran, Sydney Weese, Cydni Williams Md

Student Research Symposium

Traumatic brain injuries are the result of a sudden external blunt force to the brain and can result in long-term complications or death. In pediatrics, it is the leading cause of acute and chronic sleep wake disturbances, as well as cognitive deficits, which can lead to a reduction in the quality of life. These impairments can later result in lowered performance in work and school settings or decreased psychosocial function. Although there is sufficient evidence that traumatic brain injuries contribute to is that it is unknown whether or not sleep wake disturbances contribute to an increase in the mentioned cognitive …

Hide & Cru-Seq: Investigating Potential Crucivirus Hosts With Fluorescently Labeled Protein, Marcell Devaune Richard, Nacho De La Higuera, Jono Abshier, Ken Stedman

Student Research Symposium

Cruciviruses are DNA viruses that contain a capsid protein that shares striking similarities to capsid proteins from RNA viruses. Formerly known as “RNA-DNA hybrid viruses”, this novel type of viruses suggest gene exchange between unrelated RNA and DNA viruses. However, the hosts of cruciviruses remain unknown. To investigate this groundbreaking virus genome further, utilization of the predicted viral host recognition domain (P-domain) fused to a thermal green protein and a histidine tag, allows investigation of crucivirus hosts in environments where these viruses have been discovered. Using cruciviruses that have been found in soil samples on the PSU campus, along with …

Exploring Speech Experiences, Cpib Scores, And Aac Assessment Experiences Of Autistic Aac Users With Intermittent, Unreliable, Insufficient, And/Or Expensive Speech, Karina Rayl, Pang Lee Herr, Brandon Eddy, Amy Donaldson, Stephanie Fuller, Alyssa Zisk

Student Research Symposium

There is growing evidence from the perspectives of speaking autistic people that augmentative and alternative communication (AAC) supports their self-expression and communicative agency. Despite the evidence supporting the communication effectiveness of AAC, autistic adults have reported that professionals often prioritized speech as the ideal communicative method rather than offering AAC as a communication option. This study will investigate autistic adults’ AAC assessment experiences and explore whether a modified version of the Communication Participation Item Bank (CPIB) self-rating questionnaire could be an effective tool to document the internal states of intermittent, unreliable, insufficient, and/or expensive speech. Surveys will be distributed to …

Second Language Impacts On First Language Processing, Natalie Robison, Sarah C. Creel, Sarah Elkington, Judith Kelholt, Amy Lin, Carolyn Quam

Student Research Symposium

This line of research investigates attrition (loss of fluency) of native Mandarin language (L1) proficiency with increasing proficiency in English. English uses pitch to denote intonation (e.g., “it’s there?” versus “it’s there!”), while Mandarin uses pitch to indicate word meanings; e.g., /he/ means “drink” with a high, level tone, or “river” with a rising tone. The present study delineates between two alternative explanations for the prior finding (Quam & Creel, 2017) that English proficiency correlates with attrition of Mandarin tones, but not vowels. This pattern could be explained by 1) language assimilability (L1-L2 Assimilability Hypothesis), or 2) by tone being …

Describing Shen & Shen Ming Via A Hybrid Quantum Computational Model, Alex M. Cullen, Johnny Lemau

Student Research Symposium

Definitions for Traditional Chinese Medicine (TCM) terminology within the context of quantum biology (QB) have recently been proposed. These definitions aim to elucidate concepts such as qi meridians in TCM. Our study presents a hypothesis that seeks to provide an operational definition for Spirit (Shen) and Bright Spirit (Shen Ming) in TCM via a scoping review. We propose that Shen represents physical, phenomenological proto-consciousness/consciousness in the forms of computation, such as singular particles/bits/qubits, computers, organisms, or computational strategies, whereas Shen Ming may refer to emergent, quasi-physical meta-proto-consciousness/consciousness formed by coherent relationships of multiple orchestrated/integrated units of computation; manifesting itself as …

Impact Of Testosterone Therapy On Voices In Trans-Masculine People: A Scoping Review, Samuel E. Hedine, Jeff Conn, Deanna Britton

Student Research Symposium

Treatment of trans people by speech-language pathologists (SLPs) dates back to at least the 1980s. However, the majority of early research on the voices of trans people focused on trans-women. More recently, the field of speech-language pathology has garnered more interest in the effects of testosterone therapy in trans-masculine individuals. The goal of this project is to review current research, and compile the known effects of testosterone therapy in the trans-masculine population on common acoustic indices of voice production, including fundamental frequency (pitch), decibels/sound pressure level (dB SPL; loudness) and cepstral peak prominence (voice quality). A scoping literature search was …

Construction And Mutagenesis Of Ssv1 Mutants In Extreme Viruses, Lou Ann F. O'Connor, Jono Abshier, Kenneth M. Stedman

Student Research Symposium

Archaeal viruses with unique structures such as spindle-shaped virions are found abundantly in extreme environments like geothermal hot springs around the world. Among all spindle-shaped viruses, the model Sulfolobus Spindle-shaped Virus 1 (SSV1) is best studied. Creating the lemon-shaped or spindle-shaped virion structure are two proteins, VP1 as the major capsid protein, and VP3 as the minor capsid protein. The primary structure of VP1 consists of a proteolytic cleavage site at position 66 that is believed to be necessary for virus evolution. Recent studies showed that genetic mutation of the amino acid, glutamate (E) at position 66 in VP1 which …

Feesability Of Laryngeal Endoscopy Simulation Labs In Student Training: A Scoping Review, Anna Thut

Student Research Symposium

Fiberoptic Endoscopic Evaluation of Swallowing (FEES) involves passing a flexible endoscope through the nose and down the throat to provide a detailed view of the throat, airway, and vocal folds. With the scope in place, people can eat and drink, allowing the clinician to evaluate for safe swallowing. Speech-Language Pathologists (SLP) use FEES for diagnostic evaluation and to gauge therapy progress and effectiveness. Simulation training on a low or high-fidelity model may provide a bridge for SLP graduate students to gain competency before being introduced to FEES in a clinical setting. This review aims to gather evidence on the use …

Respiratory-Swallowing Coordination In Motor Neuron Disease: A Scoping Review, Mariam Z. Mansoor

Student Research Symposium

Respiratory-swallowing coordination (RSC) is essential for providing efficient breathing and optimal swallowing function. Most commonly used methods of measuring RSC include nasal thermistry, and respiratory inductance plethysmography (RIP) to determine direction and durations of airflow. Outcome measures include swallow apnea duration (SAD) and respiratory phase pattern (RPP), i.e., direction of airflow pre- and post-SAD. The goal of the current project was to conduct a scoping literature review of RSC, focusing on the motor neuron disease (MND) population, including people with amyotrophic lateral sclerosis (ALS). A multi-engine literature search was conducted in 2023-24 via PubMed and Google Scholar. No limitations were …

The Effect Of Whey Protein On Gluten-Free Rolls, Maeci Armstrong, Lindsay Jarman, Sara Marshall

Student Research Symposium

Growing numbers of people developing celiac disease and gluten intolerances have increased the demand for gluten-free products in the United States. 1 Many gluten-free breads are low in protein and lack the desired texture, volume, and flavor that can be found in most standard wheat bread products. Whey protein has been shown to increase the protein content in bread and mimic gluten in creating a protein network within the dough to produce the desired texture. 1 This experiment aims to determine the effect on texture, moisture, flavor, volume, cell structure, and acceptability when whey protein isolate is added in 4 …

Observing The Variations In Peanut Butter Cookies - Replacing All-Purpose Flour To Maximize Protein Intake, Mia Knight, Joy Bruneel, Jessica Mills, Ashley Sorensen

Student Research Symposium

Protein plays a vital role in every human’s life. This macronutrient is essential in the diet for cell formation and repair. Protein powder, a nutritional supplement, is used to help build muscle, repair tissue, and make enzymes and hormones. Protein powder has also been found to help people lose weight and tone their muscles. Since some people have trouble getting enough daily protein, specifically athletes and elderly individuals, this study aims to research and learn the effects of substituting almond flour, whey protein powder, and soy protein powder in place of all-purpose flour to achieve a quality-tasting, protein-packed peanut butter …

Speech Intelligibility Assessment: Predicting "Noncompliant" Listener Behavior, Briggs Kroff

Student Research Symposium

Purpose: When researching speech intelligibility among people with dysarthria, convenience sampling has typically been used to recruit listeners. A new alternative online crowdsourcing method, Mechanical Turk (MTurk), results in ecologically valid results, but outlier results are often removed from the analysis and considered 'noncompliant'. This study aims to examine whether or not there is a relationship between age, gender, speech/language/hearing impairment, and whether someone is 'noncompliant'.Methods: Sixteen speakers, both with and without dysarthria, were recorded while they read prewritten sentences. Research participants found through MTurk then listened to the sentences and transcribed them. They also were asked questions including their …

The Effectiveness Of Translation Apps And Understanding The Flaws Of Language Learning In Classroom Settings, Mia Knight

Student Research Symposium

There are over 7,000 languages spoken around the world. In the past twenty years alone, the internet has digitized and improved much - including translation apps. With apps specific to particular languages and topics and with the ability to access so much information at the touch of a finger, it is easy for individuals to engage themselves in communicating with those who speak different languages. According to the Pew Research Center, in 2022, language learning in the United States was at its lowest point in twenty years.2 Conversely, translation app use has increased. Although these mobile translation apps, e.g., Google …

Applying A Health-Risk Model To Climate Change Communication: The Benefits And Barriers Of The Eppm For Inciting Carbon Footprint Reductions, Mikenna Debruin

Student Research Symposium

Whereas over 99% of the scientific community believes in the concept of anthropogenic climate change, lay support is still lagging behind. I suggest three key factors to lagging lay support: 1) complexity, 2) manufactured scientific controversy, and 3) doom-and-gloom framing. Because of these factors, individuals are less willing believe in the prevalence of human-induced climate change, nonetheless do something about it. The Extended Parallel Process Model (EPPM), however, presents a model to assuage eco-anxiety and counter psychological distance from the problem. The EPPM, proposed by Kim Witte in the 1990s, combines appeals to threat and appeals to efficacy to contextualize …

Augmentative And Alternative Communication Course Design And Features: An Analysis Of Course Syllabi And Calendars, Celine Goodbody, Hosanna Broderick, Brandon Eddy

Student Research Symposium

Augmentative and alternative communication (AAC) is an area of clinical practice that supplements or compensates for impairments in speech-language production and/or comprehension (ASHA, n.d.). A survey study by Johnson and Prebor (2019) found 86% of graduate speech-language pathology (SLP) programs offered an AAC course, though half (49%) suggested their students were underprepared to provide AAC services. High-quality graduate training, including AAC coursework, has been suggested as a solution to prepare clinicians to provide AAC services. Recently, Sauerwein and Burris (2021) surveyed AAC course instructors at accredited SLP graduate programs to analyze AAC course design features. Sixty-four (24.2%) programs responded to …
