Design And Construction Of An Affordable Adjustable Repetition Rate Optical Frequency Comb, Christopher Latchford

Physics, Astronomy and Geophysics Honors Papers

Two different adjustable repetition rate optical frequency combs were designed and constructed with off-the-shelf components, including several improvements to established erbium fiber designs. These designs were assembled at a fraction of the cost of a commercial comb. Both combs were constructed with a repetition rate of roughly 100 MHz, with one combs tuning range being 2 MHz and the others being 3 MHz. These combs followed different designs, the first being a modification of an established nonlinear polarization rotation (NPR) design, the second being a modification to a “figure 9” design. A stabilization control loop for frep achieved long-term drifts …

Preserving The Horizon: How Henry David Thoreau And William Morris’S Environmental Aesthetics Ward Off Ecoapocalypse, Esther Kw Mack

West Chester University Master’s Theses

To add to the current the current ecodiscourse, this thesis sets out to reimagine contemporary ecological discourse through the analysis of nineteenth century figures Henry David Thoreau and William Morris, two countercultural figures who dedicated their lives to protecting nature. Where Thoreau’s “Autumnal Tints” highlights autumn’s tide through a scientific narrative, Morris encapsulates the four seasons’ companionship in “Verses for Pictures,” as well as his infamous textile “Acanthus.” By synthesizing ecoadvocates’s life works from around the world and positioning them as interlocutors to Asian philosophy, art, and practice merge to evolve into a profound ecorehetoric accompanied by aesthetics. As the …

The Effects Of Prenatal Alcohol And Nicotine Exposure On Later-Life Drug-Seeking Behavior And Memory Performance, Zoe Campanella

West Chester University Master’s Theses

Alcohol and nicotine are the two most commonly consumed licit substances among pregnant individuals, and the potential consequences of prenatal exposure to each drug include a variety of neurological and behavioral alterations. These may include an increased likelihood of developing a substance use disorder (SUD) and/or cognitive impairments later in life. However, 30% of pregnant individuals who report consuming alcohol also report consuming nicotine, yet the potential consequences of combined prenatal exposure are not understood. Furthermore, 40% of pregnancies in the U.S. are unplanned, meaning that drug exposure most commonly occurs during the first trimester. However, there is limited research …

Unveiling The Bacterial Communities Of Aphaenogaster: Taxonomic Composition, Developmental And Species Influences, And The Impact Of Climate Change, Lily Kelleher

West Chester University Master’s Theses

Ants are vital keystone species in many ecosystems because they provide ecosystem services such as: seed dispersal, soil bioturbation, and pest control. However, ant bacterial symbioses remain largely unstudied, but these interactions are crucial because microbes play a vital role in the ants’ overall health. Today, global climate change is impacting our biodiversity, and we can use information about how changing temperatures impact the symbiotic bacterial communities associated with ants to predict future impact. Aphaenogaster rudis and A. fulva remain understudied in terms of their bacterial community and are important North American species. For this study, ants from several colonies …

Beyond Legacy Leadership Models: Reframing Organizational Development For A Post-Digital, Systemic Era, J Sells

College of Arts and Cultural Studies

Legacy leadership models continue to dominate universities, leadership programs, and organizational development curricula. Frameworks such as the Four Colors typology, the Competing Values Framework (CVF), the Four Frames, and related personality- or quadrant-based theories were designed during a predigital era characterized by stability, linearity, and predictable organizational boundaries. However, the contemporary reality of leadership is radically different: leaders now operate within volatile, digitalized, AI-mediated, globally entangled supply value chain ecosystems. This paper proposes that legacy leadership frameworks are theoretically insufficient, structurally misaligned, and operationally outdated for developing leaders in twenty-first-century organizations. Drawing on systems thinking, digital transformation research, organizational complexity, …

The Physiological Effects Of Anabolic Steroids On The Human Body, Aedan Kerr

Undergraduate Honors Theses

Anabolic-androgenic steroids (AAS) are synthetic derivatives of testosterone used both medically and illicitly for their muscle-building and performance-enhancing properties. While clinically prescribed for conditions like hypogonadism, osteoporosis, and muscle-wasting diseases, AAS are frequently abused by athletes and recreational lifters seeking rapid physical gains. AAS increase muscle protein synthesis via androgen receptor-mediated gene transcription, but they also predispose users to tendon ruptures and various organ functions. AAS abuse is strongly associated with a host of side effects including gynecomastia, male-pattern hair loss, infertility, hepatotoxicity, erythrocytosis, dyslipidemia, insulin resistance, and hypogonadism. Cardiovascular complications such as left ventricular hypertrophy, cardiomyopathy, and myocardial infarctions …

Electronic Propulsion Engines: Revolutionizing Space Travel, Isaiah Echeverria

Undergraduate Honors Theses

Most spacecrafts rely on chemical propulsion to generate thrust and venture into the depths of outer space. They rely on principles from Newton’s three laws of motion, conservation of momentum-energy, and atomic physics. However, an electronic form of propulsion also exists providing spacecrafts an alternative opposed to the sole use of chemical energy. Electronic propulsion systems or engines last longer than current chemical spacecraft engines and are improving to produce greater amount of thrusts.

Comparing the two types of spacecraft engines shows the benefits and disadvantaged obtained by using either option as well as the main differences and similarities shared …

Adding Libraries To The Equation: Mathematical Sciences’ Underutilization Of Academic Librarians, Jennifer Lc Burke, Elizabeth C. Novosel, Daniel G. Kipnis, Rasitha Jayesekere

Scholarship and Professional Work

Academic librarians do not engage with all disciplinary departments equally. Despite equal or even greater efforts, some departments are less responsive to librarian outreach. One such department is mathematics. To understand mathematics departments’ relationships with their academic librarians, three mathematics librarians created a 20-question survey that was disseminated to mathematics faculty, instructors, and instructional staff in the United States and Canada. Of the 188 survey participants, more than a third reported that they never engage with their librarians, approximately half only do so occasionally, and a mere eight percent of participants collaborated with librarians to provide information literacy instruction (IL) …

The Right To Truth, Maureen Edobor

Scholarly Articles

This Article argues that today’s anti-CRT statutes, book bans, and “divisive concepts” laws are not isolated culture-war skirmishes but the latest chapter in a long campaign—dating back to the Lost Cause and the United Daughters of the Confederacy—to legislate white innocence as national identity. By sanitizing slavery, suppressing discussions of systemic racism, and threatening educators with punitive ambiguity, these laws flatten historical truth and convert classrooms into zones of anticipatory obedience. The result is a state-engineered amnesia that undermines the core First and Fourteenth Amendment protections the Supreme Court has recognized for more than a century, from Meyer and Barnette …

Deep Learning-Based Ensemble Two-Step Classification Of Medical Images Using Cnn Architectures And Ensemble Methods, Noreliz Alorico

Master's Theses or Doctor of Nursing Practice

Breast cancer remains one of the most common cancers amongst women globally. Early detection is crucial for improving survival rates. While mammography is widely used and an effective imaging technique, it can sometimes yield false positive or false negatives. Mammogram interpretation is highly operator-dependent, introducing variability and the potential for diagnostic errors. Additionally, mammographic images have limitations, such as low contrast in breast tissue and overlapping structures that can obscure lesions or mimic abnormalities. These limitations can lead to unnecessary biopsies or delayed diagnosis. These challenges highlight the needs for advanced and data driven diagnostic tools to support and enhance …

Spectral Divergence Prioritizes Key Classes, Genes, And Pathways Shared Between Substance Use Disorders And Cardiovascular Disease., Everest Castaneda, Elissa J Chesler, Erich Baker

Faculty Research 2025

Introduction: Substance use disorders (SUDs) are heterogeneous diseases with overlapping biological mechanisms and often present with co-occurring disease, such as cardiovascular disease (CVD). Gene networks associated with SUDs also implicate additional biological pathways and may be used to stratify disease subtypes. Node and edge arrangements within gene networks impact comparisons between classes of disease, and connectivity metrics, such as those focused on degrees, betweenness, and centrality, do not yield sufficient discernment of disease network classification. Comparatively, the graph spectrum's use of comprehensive information facilitates hypothesis testing and inter-disease clustering by using a larger range of graph characteristics. By adding a …

A balanced microbiota protects the body through mechanisms such as colonization resistance, positioning it as a key ally in the fight …

A Framework For Strengthening The Quantitative Skills/Reasoning Support Ecosystem At Small Liberal Arts Colleges, Laura J. Muller, Melissa Eblen-Zayas

Faculty Research 2025

We developed a framework for characterizing an institution’s quantitative skills/reasoning support ecosystem to consider how various activities contribute to student success in areas connected to students’ quantitative preparation. Through discussions with faculty and staff stakeholders at eight selective small liberal arts colleges, we established that the quantitative skills/reasoning support ecosystem at these institutions consists of four domains: bridge programs with a quantitative component, assessment of readiness, curricular on-ramps, and supplementary support for courses that require quantitative skills/reasoning. The framework includes questions about each domain that can be used by stakeholders in different institutional positions to reflect on existing efforts to …

Faculty Research 2025

INTRODUCTION: For years, the placenta was believed to be sterile, but recent studies reveal it hosts a unique microbiome. Despite these findings, significant questions remain about the origins of the placental microbiome and its effects on pregnancy and fetal health. Some studies suggest it may originate from the vaginal tract, while others indicate that oral bacteria can enter the maternal bloodstream and seed the placenta. However, research analyzing the vaginal, oral, and placental microbiomes within the same cohort is lacking. Additionally, it's unclear whether the placental microbiome differs between healthy pregnancies and those with complications like preterm birth (PTB), which …
