Agricultural Evidence Synthesis At A Critical Juncture: Quality Gaps And Implications For Evidence-Based Agriculture, Chao Cai, Jane Yatcilla, Justyna Czader, Sylvie Brouder, Jeffrey Volenec

Libraries Faculty and Staff Scholarship and Research

Systematic reviews and meta-analyses have become essential tools for synthesizing evidence to guide agricultural policy and practice, yet whether these syntheses are themselves conducted with sufficient rigor has rarely been systematically assessed. This study provides a field-wide assessment of reporting quality in agricultural evidence synthesis, examining whether existing reviews are conducted with sufficient transparency and rigor to support the policy and practice decisions they are meant to inform. We drew a random sample of 244 systematic reviews and meta-analyses from a bibliometric dataset of 1,709 articles published between 1997 and 2023, evaluating reporting quality using a 12-indicator rubric across four …

A Zinc Chelate Of Lysine/Glutamic Acid Reduces Alcohol-Induced Ciliary Dysfunction, Emily Do, Daren L. Knoell, Christopher Bauer, Deanna Mosley, Deandra R. Smith, Derrick R. Samuelson, Todd A. Wyatt

Journal Articles: Environmental, Agricultural & Occupational Health

Alcohol misuse is a known risk factor for pneumonia, and up to 50% of individuals who misuse alcohol are zinc deficient. Chronic alcohol misuse can lead to alcohol-induced ciliary dysfunction (AICD), preventing effective mucociliary clearance and protection against lung infection. Because zinc salts fail to alter AICD, we hypothesized a form of zinc (Zinpro Zinc LG) with enhanced cell uptake would protect against AICD. Human and mouse airway epithelial cells were treated with 50 mM ethanol for 1-24 h followed by the ciliostimulatory agents. Cilia beat frequency (CBF) and cAMP-dependent protein kinase (PKA) activity were assayed. Cyclic AMP or beta …

Comprehensive Analytical Investigation Of Tetrahydro-4h-Chromene And Dihydropyridine Derivatives, Ryan J. Burk

Chemistry & Biochemistry Dissertations

Health Professions Education

Purpose: This study investigated how medical students – as future physicians – perceive the relevance of Mintzberg’s ten managerial roles to physician leadership, and whether these perceptions change throughout medical education.

Method: In 2021, all first‑year (n = 116/116) and 98% of final‑year (n = 107/109) students at the University of Oulu, Finland completed a web‑based survey rating Mintzberg’s ten managerial roles in fulfilling physician leaders’ leadership work on a 5‑point Likert scale. Item reliability and internal consistency were examined with Cronbach’s α. Because Likert data are ordinal, medians and interquartile ranges (IQRs) were calculated, and group differences were tested …

Ghostly Grieving In Theatre’S Now Also The Dramaturgy Of Perception And The Body In Contemporary American Ghost Plays, Jacob Mann Christiansen

Graduate Student Theses, Dissertations, & Professional Papers

“Ghostly Grieving in Theatre’s Now Also” explores how contemporary American plays and playwrights stage the dead as a way of understanding theatre’s unique language for dealing with the shared, complex human experience of grief. Focusing on theatrical ghosts and other “impossible” presences, I articulate how these figures function as dramaturgical devices. I also argue that theatre’s ghosts “set the stage” (as it were) for communicable meaning-making by inviting audiences into the tasks of creation and mourning.

My work draws on performance theory (especially phenomenological accounts of theatrical storytelling), on dramaturgical analysis, and on grief studies. In this dissertation project, I …

Developing Identity After Goodbye: Social Identity Theory And How Adolescent Survivors Navigate Suicide Loss, Elizabeth Susan Lawton

Graduate Student Theses, Dissertations, & Professional Papers

Adolescents who lose a loved one to suicide, known as suicide-loss survivors, face a disruption to identity development, a life stage defined by identity formation (Adler et al., 2018) and group belonging (Pittman & Richmond, 2008). Suicide bereavement is complicated not only by grief but also by stigma, which can fracture social ties and undermine self-concept. Social identity theory (SIT) provides a framework for examining how young adults, now ages 18 to 30, reconstruct their social identities after experiencing suicide loss in adolescence. Research in other stigmatized contexts shows that adopting positive in-group identities can buffer against stigma and protect …

Hidden Wounds: Exploring Moral Injury In Childhood Exposure To Domestic Violence, Megan Elizabeth Denny

Graduate Student Theses, Dissertations, & Professional Papers

The profound impacts of Childhood Exposure to Domestic Violence (CEDV) have been documented extensively, revealing long-term psychological effects such as the potential development of post-traumatic stress disorder (PTSD) and increased likelihood of future victimization or perpetration of violence. Yet, the concept of moral injury (MI) traditionally explored in military and healthcare contexts, remains significantly underexplored in populations exposed to CEDV. This study examines the relevance of MI among individuals who experienced domestic violence (DV) during their youth. The research focused on two primary aims: (1) to describe the level and variability of moral injury-related distress among adults with histories of …

The Subadults Of Casas Grandes: A Bioarchaeological Study, Holli Kaye Mcdonald

Graduate Student Theses, Dissertations, & Professional Papers

Across the span of nearly eight hundred years, from AD 700-1450, the societies of the Casas Grandes region waxed and waned and left an astounding representation in the archaeological record. Best-known through the temporally older site of Convento (occupied during what is known as the Viejo Period) and the later site of Paquimé (occupied during the Medio Period), gradual cultural expansion and florescence across this period are witnessed through a variety of findings across decades of anthropological investigation.

Along with the artifacts and architecture unveiled during initial excavations at Paquimé and Convento, remains of 654 individuals were catalogued as well. …

The Forensic Implications Of Hydrochloric Acid (Hcl) Exposure On Dna Preservation In Human Teeth, Shaelyn Lee Zimmerman

Graduate Student Theses, Dissertations, & Professional Papers

Identity is a human right, and forensic anthropological methods are often aimed at returning identity to decedents. Three main pathways are used for the identification of human remains: fingerprints, dental records, and DNA analysis. Identification efforts may be hindered when perpetrators attempt to obscure the victim’s identity. In cases where corrosive substances, such as hydrochloric acid (HCl) are used, dental comparison and fingerprinting often fail and genetic analysis becomes the best chance of achieving personal identification.

Previous studies have shown teeth are an excellent source of DNA. Large, multi-rooted teeth, such as molars, are often preferred because they contain the …

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 …

Fit Ideal Internalization And Muscularity-Oriented Disordered Eating Among College Women: Examining Social Comparisons And Body Dissatisfaction As Serial Mediators, Nicole Graumann

West Chester University Graduate Theses, Dissertations, and Final Projects

Muscularity-oriented disordered eating (MODE) comprises rigid eating behaviors driven by a desire to be toned and muscular (Cunningham et al., 2021; Murray et al., 2019). While MODE has been widely studied among men, it is increasingly prevalent among women, and it is vital to explore its associated risk factors. In particular, the fit ideal (thin but also toned) is an emerging issue among women’s body image and could be a factor for women engaging in MODE; however, there is limited research exploring this relationship. The present study examined the relationship between the fit ideal internalization and MODE among college women …

The Importance Of Multi-Component Strategies And Healthcare Worker Compliance In Preventing Healthcare-Associated Infections: A Systematic Review, Michelle Northcut

Theses and Dissertations

Healthcare-associated infections (HAIs) remain a preventable threat to patient safety and are linked to morbidity, mortality, antimicrobial resistance, and increased healthcare costs (CDC, 2024; AHRQ, 2024). Evidence suggests that 30–70% of HAIs may be prevented through consistent application of infection prevention practices; however, implementation and adherence gaps persist (CDC, 2024). This systematic review examined the relationship between healthcare worker compliance with infection prevention practices and infection outcomes and explored how institutional and organizational factors influenced both compliance and infection outcomes.

Following PRISMA 2020 guidelines, searches were conducted in PubMed, CINAHL, ProQuest, and Google Scholar for studies published between 2015 and …

Understanding Maternal Morbidity And Mortality Rates In Georgia, Ebony Hall

Theses and Dissertations

The United States continues to have a significant concern for public health regarding the maternal morbidity and mortality rates. In contrast, women of African American descent and other marginalized populations maintain a disproportionately higher rate of pregnancy-related disparities. More specifically, in Georgia, a persistent number of disparities can correlate to a lack of access to adequate prenatal care, insurance status, and many other social determinants of health that are linked to the contribution of adverse maternal health care outcomes. The purpose of this research study is to evaluate various maternal health experiences during pregnancy, while focusing on the occurrence of …

Child Maltreatment Risk Identification In Complex Caregiving Environments: A Public Health Review Of Split-Custody And Multi-Household Family Contexts, Makenzie Lee

Theses and Dissertations

Child maltreatment remains a significant public health concern with lifelong consequences for children's health, development, and well-being. As children's caregiving environments become increasingly diverse through split-custody arrangements, blended families, kinship care, and other multi-household contexts, recognizing and assessing child safety concerns may become more complex. Although these family structures are not inherently associated with maltreatment, the distribution of caregiving responsibilities and information across multiple households may complicate child maltreatment risk identification.

This capstone presents a scoping review of peer-reviewed literature examining child maltreatment risk identification within complex caregiving environments. The review synthesized evidence related to caregiving environments, caregiver relationships, child …

Reflections On Linear B (Part 13): Sign 21 May Derive From The Ancient Egyptian 'Wedjat Eye’ (‘Eye Of Horus’ But Also Associated With Ra), Gerald Leonard Cohen

Arts, Languages and Philosophy Faculty Research & Creative Works

This article suggests that Linear B sign 21 (of unknown origin)

may derive ultimately from the Ancient Egyptian ‘wedjat eye’

(Eye of Horus). A point of special interest here is the possibility

that the pronunciation of Linear B sign 21 (designated as ‘qi’)

derives in abbreviated form from the Proto-Indo-European dual

of ‘eye’ and would therefore be the oldest Greek attestation of

that reconstructed PIE form.

Caring For Your Heart During Survivorship After Pediatric Cancer: A Visual Education Guide On Chemotherapy-Induced Cardiotoxicity, Bryona Rose Hamilton

Theses

Chemotherapy is an effective weapon in the fight against pediatric cancer. However efficient, treatment can lead to side effects that last long after a patient finishes their last round of chemotherapy. This thesis examines current research on chemotherapy-induced cardiotoxicity, a side effect of chemotherapy treatment caused by a class of chemotherapy drugs called Anthracyclines (such as doxorubicin and daunorubicin). While effective chemotherapy agents, these drugs have been known to cause late long-term heart damage when used to treat pediatric cancers such as Acute Lymphoblastic Leukemia (ALL), Acute Myeloid Leukemia (AML) and Pediatric Sarcoma. A written portion of this thesis project …

A Novel Nephron: 3d Visualization Of Glomerular Filtration In The Kidney, Cassie Young

Theses

Renal physiology, particularly the process of glomerular filtration, remains one of the most conceptually challenging topics in medical education due to its microscopic scale, dynamic pressure relationships, and structural complexity. Understanding how plasma passes through the glomerular filtration barrier requires spatial reasoning across multiple levels—from the gross anatomy of the kidney to the ultrastructure of capillaries, podocytes, and the glomerular basement membrane. This thesis addresses these challenges through the development of a scientifically accurate three-dimensional (3D) animation that illustrates glomerular filtration within its anatomical and physiological context. Designed as a visual teaching aid, the animation aims to improve comprehension of …

Dna Landscape Tool: An Interactive Webpage, Kerstyn Gay

Theses

Deoxyribonucleic acid (DNA) is a molecule that carries genetic information that makes up every organism. DNA is typically introduced into the biology curriculum starting in high school and depending on an individual's educational path can continue through college. Although taught frequently during school, elements of DNA can be difficult for students to grasp, due to the different visual representations of DNA found in various resources. For instance, when comparing an illustration of a chemically accurate nucleotide base to an abstract visualization of a chromosome learners often aren’t given enough scaffolding to see how one representation relates to the other, which …
