Shrinking Attachment Spaces, Anastasia M. Clements

West Chester University Graduate Theses, Dissertations, and Final Projects

Gluing constructions such as pushouts and other colimits are often used to attach spaces to- gether in algebraic topology. The weak topology is a natural choice of topology for attachment spaces in the context of CW-complexes and simplicial complexes because of its universal property but is insufficient for gluing together infinitely many spaces and preserving topological properties like compactness or metrizability. In this thesis, we introduce a modification of the weak topology called the shrinking attachment topology, which is defined on a space Y constructed by attaching an infinite sequence of spaces B₁, B₁, B_{3 …}

Dual Language Learner Status In Relation To Cortisol For Children In Head Start Preschool, Keala Bratsch

West Chester University Graduate Theses, Dissertations, and Final Projects

Early childhood education (ECE) has well documented school readiness benefits, especially for children facing economic hardship. Yet preschool context poses challenges that are associated with elevated stress levels and potential long-term tax on physiological systems that respond to stress. The present study examined dual language learner (DLL) status in relation to levels of the stress hormone cortisol among low-income children attending Head Start Preschool programs. Participants included 207 children ages 3- 5 years who attended preschool in 2021-22 (60.9% attending a dual-language learning school, 39.1% attending an English-instruction-only preschool; all participants meeting the criteria for low-income), and their parents or …

Five teachers, one social worker, and one special education leader participated in one-on-one interviews …

Impact Of Childhood Trauma On Perceptions Of Health: Examining The Role Of Religiosity As A Protective Factor Among Black And African American Adults, Patrice Penrose

West Chester University Graduate Theses, Dissertations, and Final Projects

Purpose: Childhood trauma has detrimental immediate and lifelong impacts on health. Black and African Americans experience higher rates of potentially traumatic events (PTEs) than the general population. Religiosity, a common coping mechanism for many who experience trauma, could serve to moderate the impacts. This study examines whether the importance of religion buffers against the impact of childhood exposure to PTEs on adult perceptions of health and assesses whether social support and/or coping mediate the relationship between religiosity and perceived health.

Method: This study analyzed data from 2,537 Black and African American participants in the National Longitudinal Study of Adolescent to …

The Role Of Technology In Education: Friend Or Fiend?, Michaela A. Morgan

West Chester University Graduate Theses, Dissertations, and Final Projects

In this paper we will be examining the role of educational technology in the United States through a critical lens with the purpose of arguing that the growing dependence on EdTech, standardized testing, and data-driven instruction has contributed to the privatization, dehumanization, and inequity of public education. Drawing from critical pedagogy, sociocultural theory, and educational research both recent and decades prior. In my paper I explore how technology in schools often functions less as a liberatory tool and more as a mechanism of surveillance, commodification, and control. We consider the historical roots of educational inequality, including eugenics, meritocracy, and colonial …

Negating Capitalist Forms Of Life And Subjectivities Through An Ontological Exploration Of Education And Pedagogy, Shannon Gallagher

West Chester University Graduate Theses, Dissertations, and Final Projects

Capitalism is not solely an economic system but is a particular form of life. Its pervasive effects have defined what it means to be human, live, and exist within the capitalist reality we inhabit. Education has been carefully curated with its formative potential in mind to form subjects who embody and act upon capitalist ontological assumptions. By doing so, education has been employed to constrain individuals to this reality with no possibility of any alternative way to be and become. This thesis argues that for education to be humanizing and liberating, there must be a critical examination of how capitalist …

Health Promotion In Tertiary Music Institutions: A Position Paper, Raluca Matei, B. Ackermann, Joy Allen, Et Al.

Faculty Works

Health promotion in tertiary music education lacks shared guidance despite rising concern for musicians’ well-being. This position paper addresses that gap with a consensus-based, evidence-informed framework developed by 122 contributors across six continents and a variety of disciplines, including musicians and student representatives. It advances a broad understanding of health—physical, psychological, social, cultural, and occupational—and positions health promotion as integral to musicking rather than an add-on. We offer seven adaptable recommendations for institutions: (1) Reframe musicianship through health-informed cultural transformation; (2) Transform institutional culture and governance; (3) Collaborate across disciplines and expertise; (4) Equip educators, leaders, and staff to promote …

Roles, Responsibilities, Considerations, And Beyond: Community Musical Care, Renate 艶子 Rohlfing

Music and Health Position Papers

Community musical care is about creating spaces where people come together, connect, and imagine healthier futures through music. It is about nurturing environments where creativity becomes a tool for well-being and collective strength. The concept is grounded in a fundamental belief: People inherently understand how to use creativity to care for themselves and others. In their daily lives, they use music to deepen relationships, process emotions, and navigate the complexities of being human. A crucial aspect of this work involves sustaining cultural practices and honoring the musical traditions that communities carry forward through generations.

Ecological Intensification Of Maize-Kale Systems In Kenya By Biofertilization And Push-Pull Management Shifts Nematode Communities, Agnes Kiriga, Johnnie Van Den Berg, Frank Chidawanyika, Solveig Haukeland, Bianca Greyvenstein, Dennis Beesigamukama, Chrysantus M. Tanga, Sevgan Subramanian, Daniel M. Mutyambai

All Peer-Reviewed Publications

Plant-parasitic nematodes (PPNs) pose a persistent threat to vegetable production in Kenya, contributing to reduced yields and soil degradation. The management of PPNs in vegetables in Kenya has largely remained unaddressed. The integration of ecological intensification strategies such as the vegetable integrated push-pull (VIPP) system and the use of black soldier fly frass fertilizer (BSFF) is gaining traction in sustainable agriculture. The aim of this study was to determine the effects of integrating VIPP and BSFF on nematode abundance and diversity in maize-kale cropping systems. Field trials were conducted in two different agroecological zones in Kenya. Field treatments involved plots …

Hepatitis C Among Persons Who Inject Drugs In New York State: Progress Towards Elimination, Meredith A. Barranco

Electronic Theses & Dissertations (2024 - present)

Background: Hepatitis C virus (HCV) infection is one of the leading causes of liver disease in the United States (US) and worldwide. In the United States today, HCV is transmitted primarily through injection drug use (IDU) and therefore disproportionately impacts persons who inject drugs (PWID), a population with a range of complex social and health needs. HCV is not vaccine-preventable but can be cured in over 90% of cases with an 8–12-week course of daily direct-acting antiviral (DAA) medication. Since approval of curative medications in 2014, various jurisdictions have developed plans to eliminate HCV. In 2021, the New York State …

Audiovisual Motion Onset Asynchrony As Expectation Violation: Effects On Memory And Liking In Media Contexts, Sijia Song

Electronic Theses & Dissertations (2024 - present)

This research presents the first systematic investigation of motion-onset asynchrony (MOA) as a form of audiovisual temporal incongruency grounded in contemporary spatial audio and extended reality (xR) systems. MOA—the delay between the onset of visual and auditory motion—was manipulated at three levels (0 s, 1.1 s, 3 s) to test its effects on cognitive (memory) and affective (liking) outcomes during short 2D animated video viewing. Guided by inverted-U models of expectation violation, it was hypothesized that moderate MOA would be associated with the highest memory performance and liking ratings and that liking would mediate MOA’s effects on memory. Across two …

The Relationship Between Interoceptive Awareness And Eating Disorder Symptomatology, Madelyn G. Johnson

Electronic Theses & Dissertations (2024 - present)

Interoceptive awareness (IA; e.g., the ability to perceive and interpret internal bodily sensations) is increasingly recognized as central to eating disorder (ED) psychopathology, yet findings remain mixed regarding whether heightened IA is protective or maladaptive. Across two studies using a sample of 654 college students (Mage = 18.74, SD = 1.56; 46% White; 58% female) from a large northeastern U.S. university, we examined (1) how specific IA facets relate to ED symptom severity, and (2) whether anxiety sensitivity (AS) helps explain these associations. In Study 1, linear regressions predicting Eating Disorder Examination Questionnaire–7 (EDE-Q7) scores showed that nearly all MAIA-2 …

Understanding The Syphilis Resurgence Among Females Of Childbearing Age: Informing Prevention Efforts In New York State, Salvatore Currenti

Electronic Theses & Dissertations (2024 - present)

Syphilis is caused by Treponema pallidum and transmitted through direct contact with infected mucosal lesions and via vertical transmission during pregnancy (i.e., congenital). Transmission of syphilis to an infant during pregnancy (i.e., congenital syphilis [CS]) can lead to early fetal death, stillbirth, neonatal death, preterm birth, low birthweight, and congenital infection in infants. The United States (U.S.) is experiencing epidemic increases in both females of reproductive age with syphilis and infants with CS. In New York State (NYS), these trends have also occurred, especially after COVID-19 emergence, and increases in reported cases and incidence rates are comparable to national statistics. …

Investigating A Mindfulness Curriculum And Prompting For Generalization On Overall Engagement Time, Caitlyn Ruggiero

Electronic Theses & Dissertations (2024 - present)

Mindfulness is a practice that has existed for centuries (Felver et al., 2022) and has been adapted to address various aspects of human life. Among the various uses of mindfulness practices, they have been adapted for use in school settings to support the use of adaptive learning behaviors in the classroom. For the target behavior to change in the natural setting, the student receiving intervention must be able to generalize the learned mindfulness skills to the classroom. The current study aimed to determine whether participation in the Soles of the Feet mindfulness intervention increased students’ overall engagement time (OET) in …

A Cross-Species Meta-Analysis Of Environmental Enrichment Effects On Cognition, Greg S. Fitzgerald

Electronic Theses & Dissertations (2024 - present)

Environmental enrichment --providing animals or people with stimulating, complex surroundings --consistently improves cognitive performance in laboratory rodents. But when similar interventions are tested in humans, the benefits are much smaller. Understanding why matters: if researchers overestimate how well rodent findings will translate, it can mislead expectations for human cognitive interventions.

This dissertation presents the first cross-species meta-analysis comparing environmental enrichment effects on cognition between rodent and human studies. Drawing on 121 studies (71 rodent, 50 human) contributing 478 effect sizes, the analysis used multilevel models with variance correction to account for the statistical dependence created when studies report multiple outcomes. …

Providers' Perceptions Of Barriers And Facilitators To Implementing Non-Pharmacological Treatment For Adults With Chronic Pain: A Meta-Synthesis, Mikhaela Mcfarlin

Electronic Theses & Dissertations (2024 - present)

Background. Chronic pain is a public health concern impacting approximately 20% of adults in the U.S. Nonpharmacological interventions are considered first-line treatments for patients with chronic pain, yet nonpharmacological interventions remain significantly underutilized. While previous research has explored barriers from the patient’s perspective, limited attention has been paid to providers’ experiences implementing these treatments. This qualitative meta-synthesis aimed to examine provider-perceived barriers and facilitators to implementing nonpharmacolgical treatments for adults with chronic pain. Methods. Independent reviewers conducted systematic searches across PubMed, PsycInfo, CINAHL, and ProQuest Dissertations using relevant (e.g., “mental health provider”, “nonpharmacological”) and applied inclusion criteria to …

Bio-Orthogonal Chemistry-Based Strategy To Turn-On And Turn-Off Crispr-Cas9 Gene Editing In Solution And In Live Cells, Bhoomika Pandit

Electronic Theses & Dissertations (2024 - present)

The CRISPR–Cas9 system is a widely popular tool for genome engineering. There is a strong interest in developing tools for temporal control of CRISPR-Cas9 activity to address some of the challenges and to broaden the scope of potential applications. In this thesis I describe two biorthogonal based approaches to either Turn-ON and Turn-OFF CRISPR-Cas9 gene editing.

In first project work I describe a bio-orthogonal chemistry-based approach to Turn-ON Cas9 nuclease activity with temporal precision. We report a TCO-acylimidazole reagent that acylates 2′-OH groups of RNA. Poly-acylation (“cloaking”) of RNA was optimized in vitro using a model 18-nt oligonucleotide, as well …

Disentangling Exercise Motivation From Eating Disorder Symptom Severity: A Dominance Analysis Of Compulsive Exercise Predictors, Sarah E. Siegel

Electronic Theses & Dissertations (2024 - present)

Compulsive exercise (CE) appears frequently in eating disorder (ED) samples but also occurs in nonclinical populations, raising the possibility that different motivational processes drive the behavior, perhaps depending on ED pathology. This study examined the relative contribution of exercise motives to CE while separating motivational variance from ED symptom severity. Undergraduate women (N = 376; 38.3% White, 28.8% Black) completed the Exercise Motivations Inventory–2 (EMI-2), the Compulsive Exercise Test (CET), and the 7-item Eating Disorder Examination Questionnaire (EDE-Q7). An exploratory factor analysis of EMI-2 subscales yielded four factors: Affective Well-being (Enjoyment, Revitalization, Stress Management), Health/Function (Ill-health Avoidance, Nimbleness, Positive Health, …

Development Of Alternative Plasma Etching Techniques For The Selective Removal Of Tan With Respect To Sioch Dielectric Materials To Enable Future Back-End-Of-The-Line Scaling, Ivo Otto Iv

Electronic Theses & Dissertations (2024 - present)

Transistor scaling has continued according to Moore’s Law for over fifty years. As transistor size decreases, adequate power delivery is required to enable transistor scaling without performance loss. Power delivery is provided by a metal interconnect network with insulating dielectric that connects the transistor level to the power source, the signal speed within this metal line network limiting transistor level switching speeds. Reduction of signal delay has moved from primarily dimension-based improvement towards adoption of conductor and dielectric materials with lower resistivity and a reduced dielectric constant value, respectively: transitioning from Al/SiO₂ to Cu/low-κ SiOCH. With this transition comes …

Advancing Periodic Time Series Analysis: Application, Bias Assessment, And Optimal Window Selection In The Variable Bandpass Periodic Block Bootstrap Method, Yanan Sun

Electronic Theses & Dissertations (2024 - present)

Time series analysis is essential for understanding long-term patterns, periodic behavior, and underlying correlations in complex datasets. The periodically correlated (PC) time series is a type of time series where the correlation structure repeats over fixed intervals. The Variable Bandpass Periodic Block Bootstrap (VBPBB) has recently been proposed as a resampling method that preserves PC structures through the use of periodogram, bandpass filters, and block bootstrap resampling. Although promising, VBPBB remains underutilized, and its limitations have not been fully examined. This dissertation advances both the application and methodological development of the VBPBB.

The first project applies the VBPBB to a …

School-Based Interventions With Youth Engaging In Bullying Behaviors: Effective Strategies From The Perspective Of School Social Workers, Elizabeth A. Crowe

Electronic Theses & Dissertations (2024 - present)

Bullying is a nationally recognized social problem associated with harmful consequences for all youth involved. Despite their crucial role in bullying interventions and student success, the practices and perspectives of school social workers are notably absent from academic literature. This survey research study sought to identify strategies that school social workers use with youth engaging in bullying behavior; distinguish which strategies are the most and least effective from the perspective of school social workers; and recognize the supports and barriers school social workers face when implementing bullying interventions.

Survey data from a sample of school social workers answered these questions. …

The Moderating Effect Of Self-Efficacy On The Relationship Between Social Determinants Of Health And Alcohol Use In A Diverse Adult Sample, Cara L. Fresquez

Electronic Theses & Dissertations (2024 - present)

Heavy alcohol consumption is associated with a range of psychosocial problems and chronic conditions, resulting in approximately 140,000 preventable deaths each year. With these potential consequences in mind, it is understandable that 46% of individuals who consume alcohol report attempting to reduce the quantity of alcohol they drink; however, very few enter formal treatment. Despite this, many people will decrease their heavy drinking over time, presumably due to individual and environmental factors, particularly self-efficacy and protective social determinants of health (SDoH). This study aimed to answer the research question “How is SDoH adversity related to the likelihood of reporting reduced …

The Maxima Method For Identification Of Principal Periodic Components In Time Series Analysis, Megan Di Maio

Electronic Theses & Dissertations (2024 - present)

This dissertation investigates methods for mean estimation in periodically correlated time series, focusing on the Variable Bandpass Periodic Block Bootstrap (VBPBB) and a novel data-driven maxima method. Time series require specific methods because of the temporal correlation in the data. Traditional methods like the General Seasonal Block Bootstrap (GSBB) account for this correlation but often produce wide confidence intervals because they cannot isolate multiple periodicities, allowing noise and other frequencies to interfere with analysis. The VBPBB method addresses this by applying a Kolmogorov-Zurbenko Fourier Transform (KZFT) filter to the data before bootstrapping, which suppresses interfering frequencies and results in narrower, …

Paying The Price: How Financial And Health Stress Can Impact Incidental Memory In The Survival Processing Paradigm, Bailey C. Hall

Electronic Theses & Dissertations (2024 - present)

Cognitive psychologists have examined how evolutionary pressures can shape memory systems and how survival-relevant information is processed. Nairne et al. (2007) established the survival processing paradigm and showed that processing information within a survival context reliably enhances later recall. Previous research has identified academic pressure and financial stress as the most influential stressors for undergraduate students (Patel & Lewis, 2023). Financial stress is widespread and influences multiple domains of life, including health behaviors and psychological well-being (Northern et al., 2010). In this study, two scenarios were created to explore financial and health stress compared to the original grassland survival scenario. …

Disability And Self-Identity: Examining Their Relationship And Impact On First-Year Students’ College Transition, Caroline A. Mcpartlin

Electronic Theses & Dissertations (2024 - present)

As students with disabilities enroll in college at increasing rates, higher education institutions (HEIs) are challenged to consider students with disabilities’ unique needs. Student development theory informs higher education policy and practice but lacks disability perspectives. As such, this study was designed to narrow gaps in disability literature and supplement student development theory with a needed disability perspective. Through an examination of how participants categorized their self-identities and identities as college students, this study investigated students with disabilities’ identity development and its impact on their college transition.

Utilizing qualitative interviews, 12 students with disabilities (SWDs) were prompted to share their …

Punishment, Fast And Slow: Five Experiments On Behavioral Economics In The Mass Incarceration Context, Nathaniel M. Schutten

Electronic Theses & Dissertations (2024 - present)

As many jurisdictions across the United States seek to reduce their prison populations, a pressing question is whether the public will support the reforms necessary to do so. Public openness to reform likely varies across policy areas, with the path of least public resistance occurring where attitudes are the most malleable and loosely held. A major challenge, however, is that traditional methods for measuring public opinion are poorly suited to identifying which policy areas are characterized by such weakly held views.

This dissertation develops a novel behavioral economics framework for identifying these areas. I theorize that when public opinion is …

Neural Network Transceiver For Ltv Mimo Channels, Iresha Amarasekara

Electronic Theses & Dissertations (2024 - present)

Eigenfunctions are commonly employed to characterize kernels in various data-driven analyses. In machine learning, eigenfunction decomposition typically relies on Mercer's theorem, which assumes kernel symmetry. However, this condition is often unmet in communication systems, where channel kernels are asymmetric due to differences in downlink and uplink propagation environments. The High-Order Generalized Mercer's Theorem (HOGMT) provides a systematic approach for decomposing multidimensional asymmetric kernels into eigenfunctions. To address the complexity of eigen-decomposition, this work introduces a baseline neural network (NN) framework HNET. The HNET framework is further enhanced by incorporating the augmented Lagrangian method (ALM) to explicitly enforce orthogonality constraints. This …

Stem Cell-Derived Developmental Models For Translational Evaluation Of Disease And Therapy, Maria B. Paredes-Espinosa

Electronic Theses & Dissertations (2024 - present)

Human development as well as congenital and adult diseases emerge from coordinated interactions among multiple cell types, regulatory programs, and tissue compartments that remain largely unresolved. Conventional simple lineage-restricted in vitro systems poorly capture this complexity. My dissertation uses human stem cell-derived developmental models to study human cardiac morphogenesis and heart diseases and application of a networked neuron platform to explore senescence-associated neurodegeneration impact on Alzheimer’s neurons.

Elongating multi-lineage organized cardiac (EMLOC) gastruloids are a synthetic embryology model that co-generates contractile cardiomyocyte populations alongside mesenchymal, endothelial, epicardial-like, neural crest-associated, and neuronal cells within a shared in vitro developmental environment. Single-cell …

Emotional Factors Influencing Adaptive Memory: An Examination Of The Role Of Valence In The Survival Processing Effect, Dailyn Q. Clark

Electronic Theses & Dissertations (2024 - present)

Encoding information (e.g., words) in terms of their survival value produces enhanced recall relative to encoding the same information in terms of its value to other schematically similar situations (Nairne et al., 2007). In the survival memory paradigm, a scenario focused on imagining being stranded in the grasslands of a foreign land is followed by the rating of individual words (e.g., orange, mountain) as to their relevance to that scenario (Nairne et al., 2007). Using an incidental test of memory, it is often revealed that memory for those words is higher than for those same words encoded under non-survival, control …

Social Class Differences Between Client And Therapist: A Grounded Theory Study Of Working-Class Clients' Perspectives, Micah Herman

Electronic Theses & Dissertations (2024 - present)

Although a substantial body of research highlights the importance of broaching differences related to race, ethnicity, gender, and sexual orientation in psychotherapy, considerably less attention has been paid to social class, a dimension of socio-cultural identity that profoundly shapes individuals’ life circumstances, their sense of self, and their relationships with others. In recognition of our limited understanding of how working-class clients perceive and respond to class-based cultural differences between themselves and their therapists, the present grounded theory study addressed (1) how working-class clients experience and make meaning of social class differences in the therapeutic relationship and (2) what clients see …
