The Role Of Mscs In The Il23/17 Pathway And Their Response To Mechanical Stress, Norma Aileen Dominguez Jimenez

Honors Theses

Mechanical stress plays a central role in shaping cellular behavior within skeletal tissues. At the enthesis, where tendons and ligaments attach to bone, repeated mechanical loading is strongly associated with inflammation and the development of ankylosing spondylitis (AS). Although mesenchymal stem cells (MSCs) are known to contribute to tissue structure and repair at these sites, their potential role in inflammatory signaling, particularly within the I 23/IL 17 pathway, remains unclear. In this thesis I investigated whether MSCs are capable of expressing cytokines involved in this pathway and how mechanical stress and differentiation influence this expression. Using the mouse derived C3H/10T1/2 …

Racial Capitalism And Black Maritime Geography In 19th Century Portland, Maine, Jeremy Harrison

Honors Theses

Portland, Maine, is located on the rocky shores of the Atlantic Ocean and has served as home to a diverse population that has benefited from the economic and social aspects of the shipping and trading industry. This port city in one of the northernmost regions of the United States was one of the last stops for ships carrying goods before reaching the city centers of the Americas and Europe. As a result, during the late 18th and early to mid-19th centuries, skilled and unskilled Black laborers from somewhat fringe regions within the Atlantic migrated to Portland in search of not …

The Efficacy Of Hybrid Manufacturing For High Stress Automotive Components, Logan Trimmer

Harrisburg University Other Works

The goal of this research was to establish the viability of using hybrid manufacturing for automotive applications. By verifying that high-stress components can be created, it can be assumed that any other lower stress part could be made to match the strength requirements. A limiting factor of adoption for hybrid manufacturing is how new the technology is. Studies on time and cost were performed allowing for comparisons with traditional manufacturing technologies (casting, forging, milling) used in automotive applications. This research utilized a Haas Automation UMC750 5-axis CNC mill with a Meltio laser wire direct energy deposition attachment. Fusion 360 was …

Three-Photon Rydberg Eit Lineshape Analysis In Rubidium, Jackson Lake

This detection technique was studied by characterizing the lineshape parameters of the EIT transmission peak, specifically the height, width and area of the transparency window as functions of the dressing and coupling laser powers. With the goal of characterizing the linewidth of the transmission signal, a confocal etalon was built and implemented in the optical setup to perform frequency calibration of …

Brewing Resilience: Cooperatives, Micro-Mills, And The Quest For Survival In Costa Rica's Changing Coffee Landscape, Leila N. Iredell

Honors Theses

This thesis examines how different organizational models in Costa Rica's coffee sector shape producers’ ability to capture value, build resilience, and sustain rural livelihoods in a rapidly changing global market. In comparing traditional cooperatives and new micro-mills, I examine specifically how control over the value chain, access to markets, and social infrastructure differ across models and what these differences mean for the farmers who depend on them. This project analyzes how the collapse of international price agreements and decades of market volatility drove producers toward new strategies, from independent processing and direct trade to coffee tourism. Costa Rica stands as …

Bridging Physics-Based Modeling And Machine Learning To Predict Material Behavior: Applications In Fatigue Crack Growth And Dielectric Property Characterization, Ansan Pokharel

Graduate Theses, Dissertations, and Problem Reports (ETD)

This dissertation integrates physics-based modeling with machine learning (ML) to predict how materials behave under complex thermal and mechanical conditions. A key innovation of this work is the use of finite element analysis (FEA) to supplement experimental data. This approach creates more diverse and representative synthetic datasets, helping to reduce the limitations and biases that arise when training ML models solely on experimental measurements. The research focuses on two applications: improving the prediction of fatigue properties in superalloys and estimating temperature-dependent, high-frequency dielectric properties relevant to microwave-based chemical processing.

In the first study, low-cycle fatigue experiments were performed on the …

Be A Man: Hypermasculinity And Hostile Attribution Bias As Predictors Of Violence, Kaley Nicole Potter

Graduate Theses, Dissertations, and Problem Reports (ETD)

In recent years, violence has risen to record-high numbers in communities and correctional facilities, with men perpetrating the vast majority of violent crimes. Hypermasculine values (e.g., power, aggression, and domination) have been linked to aggressive and violent behavior. Hostile attribution bias, which leads individuals to attribute hostile intent to neutral or ambiguous stimuli, has also been linked to aggression.

The current study used structural equation modeling (SEM) to examine hypermasculinity and hostile attribution bias as predictors of proclivity for violence, comprised of aggression and historical violence. The model was iteratively modified to assess changes in model fit and constructs. Male …

Ai-Assisted Task Completion: Consumer Sentiments By Effort Level, Jason Mickey Martin

Graduate Theses, Dissertations, and Problem Reports (ETD)

This study examines consumer anger in reaction to firms’ use of artificial intelligence (AI) to assist them in the completion of tasks. Specifically, we focus on instances when AI supplements rather than replaces human effort. Using cognitive appraisal theory and psychological contract constructs, this research investigates how the amount of effort consumers invest into a service review and the effort reciprocated by firms influences emotional reactions. Across two studies, using scenario-based experiments, we find that consumers report higher levels of anger when AI is used to aid in responding to high-effort reviews compared to low-effort reviews. The results suggest that …

Statistical Analysis Of Evidence In Criminal Cases, Giuliana Leon Carrillo

Graduate Theses, Dissertations, and Problem Reports (ETD)

Ideally, the evaluation of relevant forensic evidence must corroborate the hypotheses that the prosecution and/or the defense holds regarding the commitment of a crime. Therefore, optimal forensic evidence would be the one that can be found all the time under the same circumstances, and cannot be found otherwise, making the forensic scientist able to evaluate this evidence given the hypotheses provided. Nevertheless, this is hard to find, as ideal evidence being only a concept.

In this project, the probabilistic interpretation of relevant forensic evidence investigated in criminal cases with the aid of Wigmore charts and Bayesian networks was proposed. Using …

Three Essays On Option Markets, Fangzheng Ou

Graduate Theses, Dissertations, and Problem Reports (ETD)

This dissertation includes three essays examining index option and stock option markets. The first essay investigates the pricing kernel puzzle by examining S&P 500 index option returns and empirical pricing kernels across expiration dates ranging from one month to one year. We document that at short maturities, out-of-the-money call option returns are negative and decrease with the strike price, while at long maturities, at least some are positive and increase with the strike price. Empirical pricing kernels predominantly exhibit a W-shape at short maturities, with this pattern becoming less pronounced and evolving toward a monotonically decreasing curve at longer maturities. …

Hyena: An Observing System Simulation Experiment For Hypothetical Energetic Neutral Atom Imagers, Joel Tibbetts, Amy Keesee, Matina Gkioulidou, Robert Demajistre, Viacheslav Merkin

Faculty Publications

Mesoscale plasma sheet flows are widely understood to be a critical component of the overall picture of energy, particle, and magnetic flux transport during periods of geomagnetic activity. Without simultaneous measurements with true global coverage, the short lifetime (~10 min) and localized spatial extents (~1–3 R_E in azimuth) of these structures make obtaining a global picture of their contributions to stormtime magnetosphere dynamics difficult to characterize. Energetic neutral atom (ENA) imaging can enable remote mapping of plasma energization in the magnetosphere; however, its line-of-sight integrated nature, coupled with the challenging-to-characterize attributes of the target physical phenomena, means that numerous …

The issue of book bans has moved to the forefront of public and political debate over the past few years. Anti-censorship advocates who defend against these challenges have yet to be studied. The purpose of this study was to examine the beliefs and worldviews as expressed by those defenders in a public forum—Reddit. Data in the form of Reddit threads was collected from subreddits belonging to states that have seen the greatest number of book challenges. This data was subjected to discourse analysis, first manually, then by qualitative analysis software (MAXQDA). Analysis revealed that defenders spent a majority of discursive …

The Conservation Value Of Silvicultural Systems For Breeding And Post-Fledging Bird Communities In Northeastern North America, Christopher Andrew Liazos

Antioch University Dissertations & Theses

Forest bird community decline in the eastern United States is partly due to the lack of early-and-late-successional forests stemming from historic land use. Silviculture can create underrepresented forest age classes and structures to support avian communities during the breeding and post-fledging periods. In southwestern New Hampshire, we conducted a case study evaluating avian conservation value indices across silvicultural systems. Our goal was to observe how avian conservation value indexes and abundance differed between recently managed and unmanaged stands. We surveyed 215 breeding and 118 post-fledging points across 22 sites using point counts and vegetation surveys. Conservation values in the breeding …

Storytelling And Equity: A Program Evaluation That Promotes And Supports Narrative-Based Learning And Open Dialogue Practices At Higher Ed Institutions, Regis A. Peeples

Antioch University Dissertations & Theses

On college campuses worldwide, storytelling functions as a primary method for transmitting and affirming knowledge. It serves to validate lived experiences, acts as a relational teaching tool, and supports theoretical inquiry. Given that teaching is inherently political, storytelling can also perpetuate hate, oppression, and other social harms within academic environments. Even when educators use storytelling constructively, limited training exists on the full range of its impacts on students, particularly in terms of what may be described as “dangerous” storytelling. Dangerous storytelling refers to narratives, intentional or authentic, that reinforce or cultivate phobias about physical appearance (e.g., race, culture, nationality), propagate …

How To Reduce Inpatient Violence: A Theory Synthesis From Four Models, Arthur Walker

Antioch University Dissertations & Theses

Working in an inpatient setting inherently involves an increased risk of violence. This violence can affect both staff and patients alike and can lead to psychological trauma, serious bodily injury, and even death. To mitigate this risk, many models for preventing inpatient violence have been proposed for hospitals to implement. However, the evidence for the efficacy of these methods is inconsistent, and the theoretical underpinnings are varied and slim. This dissertation seeks to improve these models by re-examining the theoretical structures for common themes of four models for inpatient violence reduction and proposing additional recommendations informed by this synthesis. First, …

A Qualitative Analysis Of Fitness Wearable Use And Embodiment, Lucas Brandt

Antioch University Dissertations & Theses

Wearable fitness technologies have become increasingly integrated into contemporary health and wellness culture, providing users with continuous access to physiological and behavioral data related to movement, sleep, stress, recovery, and overall health. Research has demonstrated that wearable devices can increase physical activity and support health behavior change (Ferguson et al., 2022; Koivisto & Hamari, 2019). Although less is known about how these technologies influence individuals’ lived experiences of their bodies. Understanding this relationship is particularly important given growing concerns regarding embodiment, self-surveillance, and the psychological effects of health-tracking technologies (Bergsland, 2017; Rapp, 2021). Drawing on theories of mind-body connection and …

Bi+ Cismale Experiences With Straight Cismale Friends, Taylor M. Hardock

Antioch University Dissertations & Theses

Minority Stress Theory (2006) posits that individuals with a marginalized sexual identity have unique challenges and stressors. Bisexual+, or bi+, individuals have particular stressors related to not holding a monosexual identity, including specific mental health challenges. Research has shown that friendship can have many positive benefits on individuals, though the literature looking at friendship among bi+ identifying people is very limited. This qualitative study investigates the experiences of friendship between bi+ and straight cis men, especially as they may relate to minority stress and experiences of resilience and community belongingness. A thematic analysis was utilized to understand the personal experiences …

Doctoral Trainees’ Experiences Of Vicarious Trauma Within Inpatient Settings: An Exploratory Study, Melissa Neitlich

Antioch University Dissertations & Theses

Vicarious trauma (VT), first coined by Irene Lisa McCann and Anne Pearlman, is described as a pervasive and cumulative impact of working with survivors of trauma, resulting in changes to the therapist’s identity, worldview, psychological needs, beliefs, and memory. In spite of the unique vulnerabilities of doctoral trainees for experiencing VT, there is limited research on the impact of VT among doctoral trainee populations, as most of the extant literature focuses on the impact of VT in middle- to late-career psychological practice. In this primarily qualitative dissertation, I examined trainees’ experiences of vicarious trauma within various inpatient settings using the …
