From Public To Policy How Jellyfish Data And Citizen Science Can Be Used For Biodiversity Management, John Terenzini Jan 2026

From Public To Policy How Jellyfish Data And Citizen Science Can Be Used For Biodiversity Management, John Terenzini

School of Biological and Marine Sciences Theses

Long term biodiversity data is necessary for detecting biological and ecological changes to marine ecosystems. The data can inform marine policy, yet data are often lacking for some species and traditional data collection approaches can be logistically challenging and expensive. Jellyfish are one taxon for which data are lacking, and data collection can be challenging due to their life history traits and the inherent challenges of marine research. This research aims to provide evidence for the importance of monitoring jellyfish, demonstrate the effectiveness of citizen science for monitoring jellyfish, and examine how jellyfish monitoring data can inform international frameworks. The …

Social Dirt Or Fertile Soil: A Phenomenological Study Of Contingent Faculty, Ann M. Hiloski-Fowler Jan 2026

Social Dirt Or Fertile Soil: A Phenomenological Study Of Contingent Faculty, Ann M. Hiloski-Fowler

West Chester University Graduate Theses, Dissertations, and Final Projects

The experiences of contingent or adjunct faculty affect their professional identity development. Contingent faculty use has increased since the 1970s. By 2013, two-thirds of U.S. higher education faculty were contingent (Finkelstein et al., 2016). While institutions use contingent faculty to fulfill their educational missions (Haviland et al., 2017; Kezar & Sam, 2011; Kimmel & Fairchild, 2017), their status as academic laborers stigmatizes them in academia, developing what Levin and Shaker (2011) term a “hybrid identity” (p. 1479), as both professionals and laborers, professors and temporary employees. Historically, the professional status of the professoriate has been defined on the tenure track …


Factors That Impact K-6th Grade Teachers’ Sense Of Self-Efficacy: A Mixed Methods Study, Becky A. Eckburg Jan 2026

Factors That Impact K-6th Grade Teachers’ Sense Of Self-Efficacy: A Mixed Methods Study, Becky A. Eckburg

West Chester University Graduate Theses, Dissertations, and Final Projects

Although there have been efforts to narrow the "achievement gap," research shows that the academic achievement levels of students in low socioeconomic school settings are likely to be significantly lower than the academic achievement levels of students in higher socioeconomic school settings (Babayiğit et al., 2021; Rahman et al., 2024). Studies also show that teachers have a significant impact on their students' growth, no matter what their academic setting may be (Petek & Pope, 2023), and that collective teacher self-efficacy is a significant factor in positive student achievement (Hattie, 2008). If targeted professional development could support teachers' self-efficacy, student achievement …


Structures Of Fantasy In Terry Gilliam's 'Time Bandits', Sean Fash Jan 2026

Structures Of Fantasy In Terry Gilliam's 'Time Bandits', Sean Fash

West Chester University Graduate Theses, Dissertations, and Final Projects

Terry Gilliam’s use of fantasy genre conventions in his filmography is obvious in presence, but elusive in understanding.  Time Bandits, as an early entry into this filmography, simultaneously seems to mock and embody these genre conventions.  This paper seeks to find a way to understand Time Bandits on a structural level through existing frameworks in fantasy criticism and to see what deeper meanings the film holds behind its silly, fantastical presentation.  These structural templates of analysis are John Clute’s “full fantasy model” from his Encyclopedia of Fantasy and Farah Mendlesohn’s “portal quest fantasy” from her Rhetorics of Fantasy.  By deconstructing …

Catwalk Xt Enables Sensitive Detection Of Locomotor Deficits After C2 Hemisection And Integrates Readily Into Ongoing Experimental Workflows In Adult Female Rats, Aaron L. Silverstein, Christopher M. Calulot, Christopher J. Mclouth, John C. Gensel, Warren J. Alilain

Biostatistics Faculty Publications

Over half of all spinal cord injuries (SCIs) in the United States occur at the cervical level and often cause both life-threatening breathing dysfunction and profound locomotor deficits. Although the C2 hemisection (C2Hx) model is vital for study of breathing dysfunction after experimental SCI, post-C2Hx locomotor deficits have only been assessed by metrics such as the Martínez Scale and ladder tests, which require time-intensive scoring by human observers. However, the CatWalk XT Gait Analysis system (Noldus Information Technology) delivers automated, quantitative assessment of interlimb coordination, gait cycle, and paw function, providing robust locomotor data in a time-efficient and practical manner. …

Raising The Profile Of Collaborative Biostatisticians In Team Science, Margaret R. Stedman, C. Christina Mehta, Emily Slade, Patricia L. Hibberd, Glenn M. Chertow, Robert H. Podolsky, Sowmya R. Rao Jan 2026

Raising The Profile Of Collaborative Biostatisticians In Team Science, Margaret R. Stedman, C. Christina Mehta, Emily Slade, Patricia L. Hibberd, Glenn M. Chertow, Robert H. Podolsky, Sowmya R. Rao

Biostatistics Faculty Publications

Recent emphasis on transdisciplinary teams in science offers an opportunity for biostatisticians to assume roles beyond data management and analysis. Biostatisticians contribute to all phases of research, from hypothesis formulation and rigorous study design to data analysis and interpretation. Yet, their contributions are often underrecognized. We argue for better integration of biostatisticians in research training and team structures. Postgraduate physician-scientist training should include mentorship from biostatisticians and education on collaborative skills. Fully integrating biostatisticians as co-investigators improves rigor, reproducibility, and innovation. Institutional support, including protected time and updated promotion criteria, is essential to support sustained collaboration. Structural changes must address …

Rethinking Team Science Metrics Through Collaborative Guideposts, Kristen J. Mcquerry, Kelsey Karnik, Megan E. Hall, Caitline Phan, Yana Feygin, Emily Slade Jan 2026

Rethinking Team Science Metrics Through Collaborative Guideposts, Kristen J. Mcquerry, Kelsey Karnik, Megan E. Hall, Caitline Phan, Yana Feygin, Emily Slade

Biostatistics Faculty Publications

Introduction – The increasing reliance on interdisciplinary and transdisciplinary teams has reshaped how science is conducted, yet evaluating the success of such teams remains a persistent challenge. Traditional metrics, such as publication counts, impact factors, and citation indices, fail to capture the full scope of team contributions, particularly in contexts where success may be defined by community engagement, mentorship, or long-term collaboration. Methods – In this Perspective, we introduce Collaborative Guideposts, a framework designed to align success metrics with a team’s organizing priorities. We illustrate this approach through two contrasting team models from a biostatistical collaboration center: Team A, a …

Strong social support is a protective factor in diabetes and mental health management. The purpose of this study was to examine the influence of the type of support on perceived mental health status among people with diabetes. We used data from the 2021 Household Component of the Medical Expenditure Survey (MEPS). Regression models assessed the association between mental well-being (outcome) and expected help from family, friends, and the community (exposure). Support from both friends and family were significantly associated with better mental well-being, adjusting for covariates. Secondary analyses showed that those who reported greater anticipated support from family were more …

Just Prosecution, G. Ben Cohen Jan 2026

Just Prosecution, G. Ben Cohen

Akron Law Faculty Publications

Prosecutors were once envisioned as the heroes of the criminal legal system, wielding immense power to secure justice. Yet their role remained largely untethered to a coherent, principled framework. Without clear guardrails, traditional prosecution contributed to mass incarceration, racial disparities, and punitive excesses. Progressive prosecution sought to redress these deficiencies, but a lack of cohesive theoretical grounding, accompanied by a divestiture of power, left prosecutions weak. Reform was fragmented by electoral pressures but remained subject to abolitionist critiques. This article asks readers to consider the idea of Just Prosecution as a way of reimagining the prosecutor’s role—raising the question of …


Skin Type Diversity In Image Datasets, Neda Alipour Jan 2026

Skin Type Diversity In Image Datasets, Neda Alipour

Doctoral

Image-based AI systems that analyse human skin are increasingly used in healthcare and computer vision applications. However, many human skin-based image datasets do not provide reliable information about skin type, making it difficult to assess whether these systems perform consistently across the full spectrum of skin colour. The objective of this thesis is to examine how skin type diversity is represented and measured in image datasets, and to evaluate the reliability of image-based skin type measurement methods under different imaging conditions. Using publicly available skin lesion image datasets as a well-defined and widely used sub-class of skin image datasets, this …

This study investigated how levels of perceived sexualization changed between 2007, 2012, and 2017, in Seventeen and Teen Vogue magazines. A decrease in perceived sexualization was expected across the ten-year period of time. This window of time reflects the last ten years of publication for both magazines. Research was conducted by creating and utilizing a grading system for non-explicit sexualized …


The Lived Experience Of Intimate Partner Violence For Females In Emerging Adulthood: A Qualitative Study, Laurel Dobkin M.S. Jan 2026

The Lived Experience Of Intimate Partner Violence For Females In Emerging Adulthood: A Qualitative Study, Laurel Dobkin M.S.

Selected Full Text Dissertations, 2011-

Emerging adulthood is the developmental period between ages 18 to 25 where individuals begin to explore their worldviews and develop intimate relationships. This period is important for developing a sense of identity and self (Arnett, 2000, 2014). During this period, negative events or relationships, such as intimate partner violence (IPV), may have detrimental effects (Erikson, 1968; Barreto & Frazier, 2012). While literature suggests that IPV has high rates and negative consequences in emerging adulthood (Bhattacharjee & Gopal, 2022; Centers for Disease Control and Prevention [CDC], 2024; Shen & Kusunoki, 2019), there is little research on the subjective experience of females …

Design, Syntheses And Biological Applications Of Fluorescent Probes For Nad(P)H, Hsa And Cellular Microenvironment Sensing, Adenike M. Olowolagba

Dissertations, Master's Theses and Master's Reports

Fluorescent probes have emerged as powerful tools for investigating complex biological processes due to their high sensitivity, selectivity, and capability for real-time, non-invasive imaging. In particular, the detection of key biomolecules such as NAD(P)H, viscosity-related parameters, human serum albumin (HSA), and pH is essential for understanding cellular metabolism, redox homeostasis, and disease progression. In Chapter 2, three coumarin-based fluorescent probes (A–C) were designed, synthesized, and characterized for monitoring NAD(P)H levels in living cells. Probes A and B feature coumarin–cyanine hybrid structures linked via vinyl and thiophene bridges to 3-quinolinium acceptors, respectively, while probe C incorporates a dicyano moiety to replace …


Nondestructive Evaluation Of Additively Manufactured Parts Using Resonant Inspection And Frequency Domain-Based Correlation Criteria, Gita Deonarain Jan 2026

Nondestructive Evaluation Of Additively Manufactured Parts Using Resonant Inspection And Frequency Domain-Based Correlation Criteria, Gita Deonarain

Dissertations, Master's Theses and Master's Reports

Additive manufacturing (AM) enables the production of highly customized and geometrically complex components; however, these parts remain susceptible to a wide range of defect types and severities. The combination of complex geometries and distributed defects presents a significant challenge for post-process nondestructive evaluation (NDE). Conventional inspection techniques, such as computed tomography and ultrasonic testing, are often limited by geometry, material, accessibility, and cost, while in situ monitoring is not yet sufficiently mature to replace post-process inspection.

This dissertation establishes the Frequency Domain Assurance Criterion (FDAC) as a quantitative, vibration-based framework for defect detection in AM components. FDAC captures spatial–spectral correlations …


Reconciling Discretion With The Rule Of Law: A Rawlsian Analysis Of Civil Disobedience By State Actors In Liberal-Democratic Schemes, Reid Devoge Jan 2026

Reconciling Discretion With The Rule Of Law: A Rawlsian Analysis Of Civil Disobedience By State Actors In Liberal-Democratic Schemes, Reid Devoge

Dissertations, Master's Theses and Master's Reports

This dissertation starts from the position that the stability of liberal-democratic political schemes relies on its citizens mutually accepting a basic conception of political justice. While these conceptions of justice may vary, most incorporate the inter-connected concepts of autonomy, liberty, liberalism, and the rule of law. Within this conception of a liberal democracy, a potentially destabilizing issue arises when a legislatively passed law is put into effect, but a portion of the citizens perceive it as unjust. If legitimate (i.e., lawful) actions do not sufficiently resolve the concern, civil disobedience (i.e., disobeying the law) is a potential recourse, but this …


Shm For Incipient Buckling Detection In Overloaded Structures Using Nonlinear System Identification Algorithms On Redundant Data Sets, Padmanabh Shridhar Desai Jan 2026

Shm For Incipient Buckling Detection In Overloaded Structures Using Nonlinear System Identification Algorithms On Redundant Data Sets, Padmanabh Shridhar Desai

Dissertations, Master's Theses and Master's Reports

Structural health monitoring (SHM) detects and characterizes damage to predict failure, but failures such as buckling, which are not predicated on traditional damage modalities, are harder to detect. Direct load measurements are costly and difficult to implement (especially for dead loads) as they require copious numbers of sensors, which must be installed before loading is present. Vibration-based detection is a good alternative because it can infer global structural characteristics with relatively few sensors. This dissertation presents an SHM approach for detecting incipient buckling in structures under excessive loads based on non-linear models fit from measurements of small lateral vibrations due …


Mechanical Fractionation Of Wheat Middlings For Application In Pyrolysis And Animal Feed, Okwudili I. Obiakor Jan 2026

Mechanical Fractionation Of Wheat Middlings For Application In Pyrolysis And Animal Feed, Okwudili I. Obiakor

Dissertations, Master's Theses and Master's Reports

Wheat middlings are grain byproducts that are underused for bioenergy production despite having a high lignocellulose content. Its use as a feedstock for catalytic pyrolysis depends on effective and sustainable fractionation to enhance efficiency and product yield. This study tested mechanical pre-fractionation (sieving and air classification) to reduce ash content of certain fractions to < 1% for catalytic pyrolysis and enrich nutrient levels of other fractions for feed applications. Wheat middlings were separated into 11 fractions using screen sizes from 106 µm to 1651 µm, and the composition of each fraction was characterized (ash, protein, structural carbohydrates, lignin, starch, and simple sugars). For cyclone separation, a full factorial design was used to study the effect of air velocity (15,18, 20 m/s) and feed rate (33, 35, 38 kg/h) on the amount of material collected in the underflow and overflow, and the composition of these fractions was characterized. Sieving showed a pronounced segregation of ash content, from 4.5% to 6.5% in wheat middlings fractions, with 5.7% being the lowest for coarse fractions which has higher lignocellulose content, and 4.5% in the fine fraction (150-212 µm). The same defined enrichment was observed in all nutrients except for protein. Starch enrichment zone were defined in the fine fractions (212 µm and below), for structural carbohydrates and lignin in the coarse fractions (600 µm and above), and for ash in coarse fractions (1180-1651 µm). In contrast, protein content was not significantly different between various fractions (p value=0.787). The fiber rich fraction (> 600 µm), suitable for pyrolysis, which have a composite ash value of 6.0% can be sorted and mixed with intermediate fractions to reduce ash to 5.3% and the remaining fractions rich in digestible nutrients used for animal feed formulation. Compared to sieving, cyclone separations did not …


Digital Technology And Women’S Health In Nigeria: A Feminist Sts Walkthrough Analysis Of Mdoc Digital Health, Edith Michael Ogbodo Jan 2026

Digital Technology And Women’S Health In Nigeria: A Feminist Sts Walkthrough Analysis Of Mdoc Digital Health, Edith Michael Ogbodo

Dissertations, Master's Theses and Master's Reports

This thesis critically examines how a Nigerian digital health platform, mDoc, represents and constructs women’s health. Drawing on Feminist Science and Technology Studies (STS) and Light et al.’s (2018) walkthrough method, the study interrogates the values, assumptions, and power relations embedded in mDoc’s design, language, and governance structures. The analysis reveals that mDoc, despite positioning itself as an equitable solution to Nigeria’s health crisis, reproduces and depoliticizes the structural inequalities it claims to address. Through its neoliberal emphasis on self-care, the individualization of structurally produced suffering, and the datafication of women’s bodies, the platform encodes gendered, colonial, and class-based assumptions …
