Douglas Fir Bending Strength At Sub-Pyrolytic Temperatures And Aftermath, David Kroeker, Aran Badasian

Architectural Engineering

Current fire design for wood framed buildings assumes a protective layer of charring and the material beyond that layer is entirely undamaged after the fire. It is documented that wood does experience a loss of ultimate capacity during a fire, however, the bulk of tests providing the reduction in capacity have been in tensile and compressive tests. The tests described in this paper were conducted to investigate the reduction in bending strengths both during and after being raised to pre-pyrolytic temperatures. These tests confirmed current design practices as laid out in the National Design Specification for Wood Construction 2024, while …

Evaluation Of Alternative Solvents For Electrospinning Occluded Scaffolds To Model Intracranial Atherosclerotic Disease In Blood Vessel Mimics, Olivia D. Rankin

Master's Theses

Intracranial atherosclerotic disease (ICAD) is characterized by a buildup of fatty plaque within the walls of arteries supplying the brain, resulting in vessel narrowing, restricted blood flow, and increased risk of ischemic stroke. While various treatments exist for ICAD, most are accompanied by high recurrent stroke rates and other adverse events, highlighting the need for further investigation and models for pre-clinical testing. Tissue engineered Blood Vessel Mimics (BVMs), consisting of a polymer scaffold sodded with human vascular cells, serve as physiologically relevant in vitro models for vascular device testing. This thesis focused on the application of alternative solvents to a …

Matlab Shake Table Control And Data Acquisition System, Abigail Austin

Architectural Engineering

The College of Architecture and Environmental Design’s (CAED) seismic laboratory shake table is used for earthquake engineering education and experimental testing. However, the existing control system is outdated and difficult for students unfamiliar with the system to operate. The objective of this project was to develop a MATLAB-based control and data acquisition application to simplify shake table operation and improve accessibility, of both operation and output, for student users.

The developed application imports earthquake acceleration records, scales the input motions to the operational limits of the shake table, and executes the desires motion through the existing hardware system. Experimental data …

Electrically Evoked Emg Decomposition Using The Perturbative Generalized Series Expansion, William R. Walker

Master's Theses

Electrically evoked electromyography records the muscle's response to nerve stimulation and has been used for clinical assessment of neuromuscular function, as well as treatments such as functional electrical stimulation or stroke rehabilitation. In every muscular contraction, an electrical signal is generated. These signals come from the summation of simultaneously recruited motor units, enabling decomposition techniques to reveal information about motor unit recruitment.  By improving the ability to decompose and analyze these signals, clinical treatments involving neuromuscular electrical stimulation can be optimized and better understood. Much of the research on EMG analysis focuses on voluntary EMG, leaving a gap in the …

Develop & Test Radar Assignments For Future Graduate Curriculum, Thomas Ky Hong, Christopher William Hoferer

Electrical Engineering

With Cal Poly’s switch to semesters, many upper-level electives lack enough depth and structured content for the new 15-week format. In addition, while the Electrical Engineering department currently offers approximately five weeks of RADAR-focused laboratory material within EE 424: Intro to Remote Sensing, this limited exposure is insufficient to provide students with a comprehensive understanding of RADAR theory and practical applications. The semester conversion presents a timely opportunity to expand this existing five-week RADAR segment into a full 15-week course that integrates both lecture and laboratory content. To address the current curriculum gap, we have seamlessly extended the RADAR exercises …

Vision-Guided Motion Planning For Autonomous Catch With A Robotic Arm, Kayla Go-Oco, Ashik K. Islam, Raegan Gritzmacher

Electrical Engineering

Modern robotic systems are often evaluated using static and highly controlled tasks, such as pick-and-place demonstrations, which do not fully represent the uncertainty and adaptability required in real-world environments. A major challenge in robotics research is enabling robotic systems to perceive, track, and respond to dynamic objects in real time while maintaining accurate and reliable motion control. This project addresses these challenges by developing an autonomous robotic platform in which an OpenMANIPULATOR-Y robotic arm detects, tracks, and attempts to catch a moving tennis ball using a vision-guided control system. The system integrates YOLO-based object detection with an Intel RealSense D455 …

Increasing Lead (Pb) Screening Participation Rates In The Pediatric Patient Population At The Philadelphia College Of Osteopathic Medicine Lancaster Avenue Community Healthcare Center, Jacob Varrato

PCOM Biomedical Studies Student Scholarship

Elevated blood lead levels (EBLLs) are an ongoing public health crisis predominantly affecting children under six in low-income communities located in major cities across the United States (Zartarian et al. 2024). Chronic lead exposure due to outdated housing, polluted water, and contaminated soil is especially harmful in early childhood. Frequent hand to mouth contact at this age increases the risk of ingesting particulate matter containing lead (CDC). EBLLs can predispose children to neurocognitive deficits, cardiovascular disease, and epigenetic modifications to gene expression patterns (Collin et al. 2022). While precautionary measures and timely screening protocols greatly reduce the risk of developing …

Effects Of Mitoquinone On Doxorubicin-Induced Cytotoxicity In H9c2 Cardiac Myoblasts And 22rv1 Prostate Cancer Cells, Tia Patrick

PCOM Biomedical Studies Student Scholarship

Introduction:

Although Doxorubicin (DOX) is a widely prescribed chemotherapeutic agent, its clinical use is limited by cardiotoxicity (DIC) caused by oxidative stress, mitochondrial dysfunction, and cardiac apoptosis. Dexrazoxane (DEX) is the only FDA-approved cardioprotective agent to prevent DIC. However, DEX may induce secondary malignancy. Mitochondria-targeted antioxidants (MTAs), such as mitoquinone (MitoQ) and 10-(6′-plastoquinonyl) decyltriphenylphosphonium (SKQ1), selectively accumulate within mitochondria to scavenge reactive oxygen species (ROS) at their primary site of production. Our previous findings demonstrated that MitoQ and SKQ1 prevented the reduction in cell viability caused by DOX treatment in H9c2 myoblasts. However, it remains unclear whether MitoQ can selectively …

The Spiritual Communities Of Bronies, Amie Sexton

Theses, Dissertations and Culminating Projects

Bronies, adult, typically male, fans of the cartoon My Little Pony: Friendship is Magic, have long been regarded for seemingly breaking expectations around gender norms. This study finds that Bronies break expectations around what is expected of spiritualism. Through interviews and ethnographic observation of social media spaces Bronies frequent, it is found that spirituality based on the cartoon within the fandom is broad, diverse, and at times, normative. A proportionally-small group of fully sincere spiritualists with plural experiences and strong convictions inspire a much larger community of post-ironic aspirants. Aspirations towards spiritual experiences and the development of profound terminologies create …

"Certain" Unalienable Rights: Christian Nationalism And Beliefs About Freedom Of Speech, Emily J. Haan

Honors Projects

Christian nationalism can be defined as an ideology advocating for the fusion of Christianity with American civic life. While the First Amendment protects freedom of speech and religion, Christian nationalism has been linked to limiting the rights of those who do not fit into their vision for America. Citing the belief that America was founded as and should continue to be a Christian nation, Christian nationalists hold an exclusionary view of America, pointing to a relationship between Christian nationalist ideology and a limiting freedom of speech for stigmatized groups. This project uses data from the General Social Survey, 2021, (N …

Kitchen Table Press: A Case Study Of Regression To The Neoliberal Mean, Alaina Disalvo

Dissertations, Theses, and Capstone Projects

This thesis examines the idealistic founding of Kitchen Table: Women of Color Press in 1980 and its slow downfall, culminating in the cession of ownership of the Press to a university in 1992. It traces the ideological development of Kitchen Table Press’s key founders, Barbara Smith and Audre Lorde, and their respective relationships to the ideologies of other renowned feminist figures of the era, specifically June Jordan and Adrienne Rich. It examines the history of the Press through historical, intersectional, affective, and socialist lenses. This thesis argues that neoliberal pressures can bend even the most radical organizations away from their …

Managing Migration And Political Change: Lessons From Sweden’S 2015 Asylum Crisis For South Korea’S Emerging Immigration Era, Sean Lee

Dissertations, Theses, and Capstone Projects

The purpose of this capstone project is to analyze how two nations that have little in common in terms of geography or politics have been required to deal with immigration issues in ways that their institutions did not anticipate. One nation has been dealing with immigration-related issues for some time now, while the other nation has yet to do so. In 2015, when Sweden received approximately 162,000 asylum applications in one year alone, Sweden’s housing systems were strained, many of the municipalities were unable to keep up with the demand, and the political climate began to shift in ways that …

The Impact Of Multi-Brand Promotions On Visual Distinctiveness And Consumer Choice, Melanie Isabel Paul Austin

Dissertations, Theses, and Capstone Projects

In cluttered retail environments, marketers must often decide whether to showcase a brand alone in a single-brand promotion, or alongside other brands in a multi-brand promotion. Prior research has explored the role that different retail promotions play in consumers’ choice contexts. This research explores how multi-brand promotion versus single-brand promotions impact consumers’ purchase behavior. Study 1 uses secondary scanner data to show that multi-brand promotions lead to significantly higher sales of the promoted product compared to single-brand promotions. Study 2 replicates our secondary data findings in a quasi-field study with actual choice behavior. A series of lab studies again confirm …

An Inferential Analysis Of Lexical Networks, Christopher D. Gravelle

Dissertations, Theses, and Capstone Projects

Lexical networks are graphs where words are treated as nodes, and relations between words are treated as edges. The adoption of lexical networks in psycholinguistics is impeded by a lack of readily available inferential methods, which limits work to purely descriptive analyses with little ability to make inferences about what variables account for lexical network structure. The current research explores the use of latent space network models as a method for analyzing lexical networks. Latent space network models are latent variable regression models, which model the presence or strength of edges by estimating pairwise distances between nodes in a latent …

New Age Spirituality In Post-Secular Turkey: Navigating Secular Sensibilities And Class Privilege, Zeynep Ozbarlas

Dissertations, Theses, and Capstone Projects

The conflict between religion and secularism has been one of the major forces shaping Turkey’s socio-political landscape since the late nineteenth century. With the radical secular turn during the founding of the Turkish Republic, secularism remained the dominant force until the rise of political Islam in the 1980s. This dissertation, grounded in ethnographic fieldwork, argues that New Age spirituality, adopted by the secular upper-middle class, has become an alternative venue for the reproduction of secular sensibilities and socio-economic privilege in contemporary Turkey, at a time when the two-decade tenure of the Erdoğan regime has undermined secular hegemony.

Although New Age …

Goddess In A Trash Can: Religious Ritual Disposal In New York City Public Parks, Zoe Oro-Hahn

Dissertations, Theses, and Capstone Projects

Practitioners of Afro-Caribbean religions, including Santería, Vodou, Espiritismo, and Las 21 Divisiones, utilize the New York City Public Parks system to hold rituals, connect with spirits and ancestors, and dispose of religious remains leftover from trabajos (workings) and brujería (witchcraft). Utilizing photos from Van Cortlandt Park in the Bronx, my thesis considers the religious, political, social, and practical rationale behind this phenomenon, explores the rituals occurring, and provides policy suggestions that balance religious needs of practitioners with the safety and wellbeing of New York City’s parks.

Assessing The Influence Of Disability Views On Perceptions Of Hearing Aids Among Older Korean Adults, Stasha Lee

Dissertations, Theses, and Capstone Projects

Background

Age-related hearing loss, also known as presbycusis, is highly prevalent among older adults, yet hearing aid adoption remains low, in part due to concerns about stigma and negative social perceptions. This study aimed to examine whether attitudes towards disabilities influence perceptions of individuals wearing hearing aids among older Korean adults. It also explored the potential effects of cultural identity and the age of the individual wearing the hearing aid on these perceptions.

Methods

Ten participants completed the Attitudes and Perspectives on Persons with Disabilities (APPD) questionnaire and rated 8 different images of individuals (one younger male and one older …

New York State Excelsior Scholarship Program: A Post-Implementation Analysis Of Student Success, Eligibility, And Indebtedness – An Intersectional Study Of Black And White Female Students, Marcus I. Richardson

Dissertations, Theses, and Capstone Projects

The New York State (NYS) Excelsior Scholarship Program, introduced in 2017, was designed as a “first-in-the-nation” tuition-free initiative intended to expand college affordability for undergraduate students attending public institutions in New York State. While the program aims to increase access to higher education, its eligibility requirements, particularly the expectation that students complete 30 credits annually through continuous full-time enrollment, may disadvantage students whose academic pathways diverge from traditional enrollment patterns. This study examined the relationship between structural, financial, and academic factors and students’ ability to retain Excelsior Scholarship eligibility at the City University of New York (CUNY). Using institutional data …

Revolutionary Petunias In The Hallways: Adultification, Identity, And Black Girls’ High School Experiences, Renee Niles

Dissertations, Theses, and Capstone Projects

This thesis examines how adultification, the racialized misperception of Black girls as more mature, responsible, and self-sufficient, shapes high school experiences and identity development. Using Constructivist Grounded Theory and Black feminist epistemology, the study draws on interviews with eight Black women to explore how these experiences are interpreted over time. The study conceptualizes adultification as a form of developmental governance, an ongoing structural process that regulates perception, behavior, and identity from adolescence into adulthood.

Radiotheranostics For Gynecological Pathologies, Joni Sebastiano

Dissertations, Theses, and Capstone Projects

Molecular imaging, specifically positron emission tomography (PET), is vital for detecting disease and understanding its biological makeup. The exploitation of radiolabeled antibodies for PET imaging has proven to be indispensable to the field of molecular imaging over the last several decades. The development of radioimmunoconjugates for use in immunoPET has not only allowed for the sensitive, specific, and high-resolution detection of disease, but has also enabled a deeper understanding of the disease biology, ultimately guiding more personalized therapeutic strategies. Most typically, this technology is harnessed for the diagnosis and treatment of cancer, however more recently, the field has explored the …

Technology Disruptions In Platform Ecosystems: Ai, Market Adaptation, And Digital Resignation, Eunah Cho

Dissertations, Theses, and Capstone Projects

This dissertation examines how technological disruptions reshape behavior, competition, and user response in platform ecosystems. Bringing together two studies of generative AI in digital labor market and one study of mandatory privacy disclosure in mobile app ecosystems, it argues that platform technologies do not affect participants uniformly. Instead, their effects are mediated by market structures, competitive dynamics, and platform dependence.

The first study shows that ChatGPT shifts workers’ human capital strategies by reducing investment in specialized depth while increasing skill diversity, revealing a move from exploitation toward exploration. Yet market rewards remain uneven, as workers who integrate AI with deep …

Music Appreciation In Cochlear Implant Users: A Questionnaire, Hanna Davidson

Dissertations, Theses, and Capstone Projects

Cochlear implants provide significant benefits for speech perception in individuals with severe to profound hearing loss; however, music perception and appreciation remain challenging due to limited spectral and temporal resolution. This study examined music appreciation in post lingually deafened adult cochlear implant users, focusing on changes in enjoyment, listening behaviors, and subjective experiences following implantation. Sixteen adults completed a 36-item questionnaire assessing pre- and post-implant music engagement, perceived sound quality, and emotional responses to music. Quantitative data were analyzed using descriptive statistics and inferential statistics, and qualitative responses were analyzed thematically.

Results indicated a moderate decline in music enjoyment following …

The Hope Dionysos (After Augustus): A Post-Actian Reading Of Dionysian Imagery, Jane Horman

Dissertations, Theses, and Capstone Projects

At the center of the Roman court at The Metropolitan Museum of Art in New York stands an almost seven-foot-tall statue of an androgynous looking figure, leaning on a smaller statue of a woman. This piece, formally known as Statue of Dionysos Leaning on a Female Figure, has been nicknamed the Hope Dionysos for both the archaic statue he is leaning on, as well as the family to whose collection he belonged for many years. However, in its day, the statue occupied a complicated place in Roman culture. This paper will examine the ways in which Dionysos, specifically through …

Mediating Energy And Charge Transfer Dynamics Of Lead Halide Perovskite Nanocrystals Via Surface Chemical Approaches, Aaron S. Malinoski

Dissertations, Theses, and Capstone Projects

Energy and charge transfer are the fundamental mechanisms by which semiconductor nanocrystals interact with their external environment and underpin all light-conversion related applications. Lead halide perovskite nanocrystals (PNCs) are a relatively new class of semiconductor nanocrystals that possess a unique and dynamic surface chemical environment. Investigations into the influence of these surface chemical conditions on the electronic coupling between surface-bound molecular acceptors and the perovskite nanocrystals, and how the surface chemistry can be manipulated, in turn controlling the charge and energy transfer mechanisms, is the focus of this dissertation. Through ligand-shell engineering using commercially available, inexpensive small molecules, the surface …

Access Denied: Financial Aid Inequalities And The Economic Impact On Daca Students, Teresa D. Jordan

Dissertations, Theses, and Capstone Projects

This capstone project argues that financial aid policies in the United States create a system of structural inequality that systematically denies Deferred Action for Childhood Arrivals (DACA) recipients’ equitable access to higher education. Drawing on peer-reviewed scholarship, federal policy data, and large-scale survey research, this paper demonstrates how the categorical exclusion from federal financial aid, inconsistent in-state tuition laws, and recurring DACA renewal fees form an interlocking barrier with profound psychological and economic consequences for a population that is deeply integrated into American society. These compounding barriers force students into a framework of constrained rationality, distorting their academic major choices …

How Temporal Integration And Complexity Drive Musical Enjoyment, August Miller

Dissertations, Theses, and Capstone Projects

Music is a type of aesthetic stimulus that unfolds dynamically over time. Combining approaches from previous research on musical preferences and research on spatial integration as a driver of visual aesthetic appreciation, we investigated how the integration of musical percepts over time influences listener enjoyment and the level of agreement between the enjoyment ratings of each listener. We used a DNN tool to quantify temporal dependencies in 32 music clips and also computed complexity scores for them. Subjects listened to each music clip while using a rotating dial to provide a continuous enjoyment rating, changing the dial’s position at the …

Trans-Cyber Cinema: Digital Embodiment In Science-Fiction Films, Sophia R. Schrock

Dissertations, Theses, and Capstone Projects

This thesis aims to define the trans-cyber genre within cinema. By looking retroactively at a selection of nine films made across various decades and countries, this genre connects these films through their visualization and thematization of both trans and cyber embodiments, whereby the trans-cyber being emerges. Before the cinematic analysis and explanation of the three generic conventions selected for this thesis – transformation of body/gender; altered reality, memory, and temporality; and, radical death – the two intertwining theoretical frameworks will be established. This includes a brief summary of applicable transgender theory, and an introduction to cyborg theory (using Donna Haraway’s …

Contra La Guerra Contra Las Madres: Una Revisión Feminista De La Figura De La Madre En Las Obras De Gabriela Wiener, Marta Dillon Y Las “Madres De Soacha”, Fatima Velez

Dissertations, Theses, and Capstone Projects

This dissertation critically examines how the figure of the mother appears across a set of contemporary Latin American cultural productions. Through the analysis of the work of Peruvian writer and performer Gabriela Wiener; the literary, journalistic, and cinematic production of Argentine writer and activist Marta Dillon; and the collective work of the Colombian human rights group known as the Mothers of Soacha—particularly the participation of three of its members in the play Antígonas, tribunal de mujeres—this study proposes the concept of a “war against mothers.” In dialogue with the term coined by Rita Segato (2016), “war against women,” this …

A Hot Topic:
Congressional Polarization And Climate Change, Mercedes R.P. Wilby

Dissertations, Theses, and Capstone Projects

Scholars offer competing explanations for how congressional polarization develops and operates. The literature variously points to shifting agendas, procedural change, or member adaptation or replacement. In this project, I study how congressional polarization occurs by asking what mechanisms account for the emergence of climate policy polarization. Climate policy is a useful test case to evaluate these competing theories. As a relatively low-salience, highly technical issue that is neither new nor inherently ideological, it is not an obvious candidate for deep partisan division. Yet climate policy has become sharply polarized, extending partisan disagreement even to the underlying science.

In order to …

Implicit Attitudes Toward Hearing Aid Visibility: Conspicuous Versus Inconspicuous Hearing Aid Colors, Orly R. Ames

Dissertations, Theses, and Capstone Projects

Hearing aid stigma remains a significant barrier to treatment uptake, with device visibility frequently identified as a contributing factor. Although prior research has examined visibility in relation to hearing aid size and style, the role of color as a distinct aesthetic dimension has not been systematically investigated. The present study assessed whether hearing aid color affects implicit and explicit attitudes toward hearing aids and whether such evaluations differ across contexts. Twenty-six adults who were not current hearing aid users participated in an online quantitative multi-method study consisting of an Implicit Association Test (IAT) and self-report questionnaires. The IAT measured implicit …
