Reifsnyder, Kevin Flurkey, Jonathan R Archer, Laura Robinson, Andrea Di Francesco, Karen L. Svenson, Ron Korstanje, David E Harrison, J Graham Ruby, Gary Churchill

Faculty Research 2025

Lifespan is an integrative phenotype whose genetic architecture is likely to highlight multiple processes with high impact on health and aging. Here, we conducted a genetic mega-analysis of longevity in Diversity Outbred (DO) mice that included 2,444 animals from 3 independently conducted lifespan studies. We identified 8 loci that contributed significantly to lifespan independently of diet and drug treatment in at least one study. One of these loci also influenced lifespan in a sex-dependent manner, and we detected an additional locus with a diet-specific effect on lifespan. Collectively, these loci explained over half of the estimated heritable variation in lifespan …

Prison-Breaking From Plato's Cave, Brennan Mcdavid

Philosophy Faculty Articles and Research

This article examines the philosophical significance of nature (ϕύσις) in Plato’s Allegory of the Cave. The word is used in the protasis of the conditional clause at 515bc where Socrates proposes to inquire into ‘what the manner of the release and healing from these bonds and this folly would be if in the course of nature (ϕύσϵι) something of this sort should happen to them’. This instance of ‘nature’ has been a matter of philological and philosophical debate, with attention paid principally to the narrow passage of the allegory for reconstructing Plato’s meaning. This article argues from the standpoint of …

Staff Education To Improve Knowledge Of Phq-9 Use, Grace Eluma

Walden Dissertations and Doctoral Studies

The DNP project revolved around educating healthcare staff on using a depression screening tool known as the Patient Health Questionnaire (PHQ-9). Undiagnosed depression can affect people’s quality of life, their functional condition, and general health outcomes, making it a significant problem that needs to be addressed. The U.S Preventive Services Task Force (USPSTF) recommends using evidence-based screening tools such as the PHQ-9 to assess, diagnose, and monitor the condition’s severity. However, a few nurses use this tool despite being aware of it or misusing it, resulting in under-utilization, inappropriate assessment, and increased events. The project aimed to implement a staff …

Extracting Magnetic Exchange Interactions From Magnetic Pair Distribution Function Data Via Monte Carlo Simulations, Emma Zappala

Theses and Dissertations

The magnetic pair distribution function (mPDF) is a powerful tool used to analyze diffuse magnetic scattering data in real-space. Presently, mPDF is usually used to model real-space spin configurations of materials, offering important insights into the local magnetic structure, but not to directly probe the magnetic interactions giving rise to the magnetic structure in the first place. Using Monte Carlo simulations, a robust algorithm to simulate the magnetic structure of materials, we can connect the underlying magnetic exchange parameters to the spin configurations from experimental mPDF data. We prove this concept using a simple two-dimensional Ising model and then demonstrate …

Proportionality: Can’T Live With It But Can’T Live Without It, Geoffrey S. Corn

International Law Studies

Perhaps no other word in the international humanitarian law lexicon evokes more interest and emotion than proportionality. How States implement the rule of proportionality is perhaps the most hotly debated aspect of international humanitarian law. The indeterminate nature of the rule allows for its meaning to conform to whatever its reader wants it to mean. This is a consequence of the variables related to key provisions of the rule: How do we assess military advantage? What makes an anticipated military advantage “concrete and direct”? And most problematic of all, what is the meaning of the term “excessive”? All of these …

Gender In Translation: How The Contemporary Bible Is Challenging Androcentric Language In Translation Through Gender-Accurate And Feminist Hermeneutical Lenses, Matthew T. Gennard

Masters Theses

This Thesis surveys the changing practice of gender-accurate translation from the late nineteenth century to the present, with special consideration for the three key principles of gender-accurate translation: Generic ‘he,’ androcentric lexemes, and pronoun substitution. These focus areas are derived from an analysis of the five translation guidelines produced during the late twentieth-century gender-neutral controversy. The loss of individuality when introducing pronominal interchange or the masculine representative hermeneutical lens has left scholars divided on gender-accurate practices. This study surveys the sociohistorical development of the feminist hermeneutical lens and the changing linguistic trends of contemporary language, which challenge androcentric assumptions in …

Pigs For The Dispossessed Goat Demon: Jesus’ Exorcism In Mark 5 And Animal Interest, Michael Joseph Gossett

Masters Theses

This thesis explores how a historical-literal reading of Mark 5:1-20 can be defended against objections that claim Jesus caused or allowed unnecessary animal suffering. Contextual insights gleaned from 2nd Temple Watchers Traditions and Greco-Roman polytheism illuminate plausible symbolic value present in the deaths of the Gerasene swine. The context of Mark 5:1-20 presents a supernatural conflict compatible with Christian theology and rebel angel theodicies. Jesus’ actions concerning the Gerasene pigs are not necessarily unjustifiable examples of animal mistreatment.

Correctional Officers’ Perceptions Of Personal Safety Equipment Effectiveness, Tiffany Haigler-Sion

Walden Dissertations and Doctoral Studies

The United States has the largest correctional system and the highest incarceration rate in the world. Within this system, correctional officers (COs) serve as the primary point of contact with inmates. Existing literature suggests that the nature of inmates’ offenses often influences COs’ perceptions. Moreover, safety equipment plays a critical role in maintaining security within prison environments. Understanding COs’ experiences and perceptions regarding their safety equipment is therefore essential. The research problem is that little is known about COs’ lived experiences with and perceptions of the safety equipment they carry to keep safe from inmate severe assault. The purpose of …

Enhancing Patient Safety: Fall Prevention Through Video Education, Fithawit T. Zere

Master's Projects and Capstones

Abstract

Problem: Globally, hospital falls remain a leading cause of injuries, increased costs, short and long-term disability and emotional impact on patients/families. Despite required prevention measures, a local hospital experienced rising fall rates during 2024 (n=71);13 of these occurred in the Med-telemetry microsystem. Although multiple strategies and financial investments occurred, nursing compliance with the fall prevention “bundle” remained suboptimal.

Context: Thirteen falls resulted in $182,000 in 2024. A quality improvement (QI) project was initiated over 12 weeks after routine audits revealed inconsistency in application of several components of the required bundle: particularly, the fall prevention video upon admission.
