Birds Of A Feather: Peace And Conflict Founders Milton Schwebel And Luella Buros, Janet Carlson

Buros Center: Professional Staff Publications

Milton Schwebel, peace psychology pioneer, described Luella Buros as “a pillar of strength, her principles uneroded by age or economic well-being, her determination to struggle against social evils undiminished” (1992, p. 4). At age 90, Buros had just become the founding contributor to Peace and Conflict: Journal of Peace Psychology. Schwebel was its founding editor. In announcing the gift, he emphasized Buros’s steadfast commitment to pursuing peace, while recognizing her artistic accomplishments and her collaboration with her husband, Oscar, in establishing the renowned Mental Measurements Yearbook series (Buros, 1968; Buros, 1978; Carlson, 2023). She later provided funds to support …


Archaeoparasitology Of The Colorado Plateau, Karl J. Reinhard, Morgana Caacho Jan 2025

Archaeoparasitology Of The Colorado Plateau, Karl J. Reinhard, Morgana Caacho

Karl Reinhard Publications

Archaeoparasitology has been conducted in the Southwest for 57 years. In the first decade of the period, two pictures of parasitism emerged. Analysis of compressed organic sediments from a latrine at Elden Pueblo presented a spectrum of geohelminths not different from medieval Europe. These findings contrast pronouncedly with an analysis of coprolites from all other studies that show consistent pinworm parasitism at other sites in the Southwest. We summarize the paleoepidemiological bases for these contrasting phenomena.

North Texas Research Forum 2025

Background: Skin cancer in the United States accounts for approximately 50% of new early cancer diagnoses. Despite this, many individuals underestimate their personal risk, leading to lower engagement in preventative behaviors. Several factors may influence an individual’s perceived risk, including family history, age, race, ethnicity, skin type, and gender. While some individuals recognize their increased susceptibility based on personal, familial, and cultural experiences, others may have a lower perceived risk due to misconceptions or limited awareness. This study examines how these demographic factors influence individuals' perceived risk of skin cancer. Methods: This study analyzed data from 333 individuals aged 19 …


The Fifth (202-195 Bce) And The Sixth (170-168 Bce) Syrian Wars In The Dead Sea Scrolls: Implications For Understanding The Origin Of The Maccabean Revolt, Kenneth Atkinson Jan 2025

The Fifth (202-195 Bce) And The Sixth (170-168 Bce) Syrian Wars In The Dead Sea Scrolls: Implications For Understanding The Origin Of The Maccabean Revolt, Kenneth Atkinson

Faculty Publications

The rulers of the Seleucid and the Ptolemaic Empires fought six wars for control of the region known as Coele-Syria during the third and the second centuries BCE. These conflicts weakened both powers, allowing them to be conquered by the Roman Republic. For the Jews of Judea, the Fifth Syrian War witnessed increased conflicts in the country among its high priests regarding the nature of Hellenistic reforms and how to deal with the Seleucid Empire. These difficulties continued and led to the Maccabean Revolt at the conclusion of the Sixth Syrian War, which would eventually culminate in Judean independence from …

A Systems Organizational Model Of Professional Role Development For New Apps: Building A Train The Trainer Program, Abigail H.B. Baugh

Yale School of Nursing Digital Theses

Most Advanced Practice Provider (APP) turnover occurs within the first year of practice. It is often linked to feelings of inadequacy caused by limited professional instruction and immediate expectations of full practice integration. These challenges are compounded further in systems with inconsistent onboarding processes and underprepared trainers, further exacerbating turnover rates. At East Carolina University (ECU) Health System, turnover rates for Physician Assistants and Nurse Practitioners reached 20% and 12%, respectively, surpassing national averages (ECU Health, 2024), highlighting the urgent need for a structured onboarding approach.A system-based Train-the-Trainer (TTT) program was developed to address these issues, focusing on essential areas …

Theory And Practice In John Wesley’S Critique Of Calvinism: A Philosophical Examination, Walter Stepanenko Jan 2025

Theory And Practice In John Wesley’S Critique Of Calvinism: A Philosophical Examination, Walter Stepanenko

The Asbury Journal

On more than one occasion, John Wesley found himself engaged in debate with Calvinists in the Methodist revival. This paper philosophically re-examines John Wesley’s concerns with the Calvinism of some members of his evangelical cohort. It is argued that Wesley’s concerns fall into two types: theoretical concerns about the conceptual coherency of a view that makes God the author of sin, and practical concerns about the moral implications of a view that suggests some individuals are elect and others are reprobate. This article then attempts a principled reconstruction of these objections. It is argued that while there is a rational …

Transformer Integration, Fine-Tuning And Zero-Shot Learning For State Of Health Estimation In Li-Ion Batteries Using Large Language Models, Chinmay Nilesh Mahagaonkar

Master's Projects

In this thesis, we present a comparative analysis of the use of transformerbased and Large Language Model (LLM) models for State of Health (SoH) and Remaining Useful Life (RUL) prediction of lithium-ion batteries. With electric cars and renewable energy systems based on batteries at the forefront, the need to predict degradation accurately in order to enhance the performance and reduce maintenance costs has become imperative. Most traditional prediction methods lag the complex and non-linear characteristics of degradation in batteries, and hence the usage of sophisticated methods becomes a necessity. The research employs the CALCE dataset, which includes long-horizon cycling data …


Introducing Justice And Rights To Students Of Economics, Mark D. White Jan 2025

Introducing Justice And Rights To Students Of Economics, Mark D. White

Publications and Research

Most economics instruction is focused on outcomes, whether evaluated in terms of individual or collective welfare or well-being. This is consistent with economics’ roots in classical utilitarianism, and no consideration is usually given to the process by which these results obtain, which is a deontological concern of right and wrong. This can seem odd to economics students, especially in the context of trade-offs in which one party is benefited at the expense of another, or aggregate welfare is maximized while some individuals are harmed, with no consideration in either of rights, desert, or justice. This chapter argues for the importance …

Validating A Novel Capability Of Assessing Pathways Of Animal Water Gain And Loss, Zachary T. Steele, Karen Caceres, Zachary A. David, Lisa M. Shollenberger, Alexander R. Gerson, Seth D. Newsome, John P. Whiteman

Biological Sciences Faculty Publications

Understanding variations in the routes by which wild animals gain and lose water is challenging, and common methods require longitudinal sampling, which can be prohibitive. However, a new approach uses Δ′¹⁷OBW (Δ′¹⁷O of animal body water), calculated from measurements of δ′¹⁷O and δ′¹⁸O in a single sample, as a natural tracer of water flux. Δ′¹⁷OBW is promising, but its relationship to organismal variables such as metabolic rate and water intake have not been validated. Here, we continuously measured oxygen influxes and effluxes of captive deer mice (Peromyscus maniculatus), and manipulated their water intake and metabolic rate. We used …


Heterotrophy Of Particulate Organic Matter Subsidies Contributes To Divergent Bleaching Responses In Tropical Sclaractinian Corals, Connor R. Love, Kelly E. Speare, Michael D. Fox, Veronica Z. Radice, Kelton W. Mcmahon, Gretchen E. Hofmann,, David L. Valentine, Marie E. Strader Jan 2025

Biological Sciences Faculty Publications

Heterotrophic feeding on plankton and particulate organic matter (POM) by tropical Scleractinian corals is known to aid in the resistance and recovery from thermally induced bleaching. However, the relative importance of heterotrophy in promoting bleaching resistance and recovery is likely to vary based on ecological context and the severity of heat stress. In 2019, the Pacific Island of Mo'orea experienced mass coral mortality during a widespread marine heatwave. Many Acropora hyacinthus colonies on the shallow reef slope (5 m) were resistant to bleaching, while colonies on the deeper fore reef (14 m) often bleached and subsequently recovered, despite similar thermal …

Form And Function In Mobulids: A Comparative Analysis Of Filter Morphology With Bioinspiration Applications, J. B. Teeple, S. R. Kahane-Rapport, K. E. Cohen, L. Hamann, J. A. Strother, E. W. M. Paig-Tran

Biological Sciences Faculty Publications

Mobulas (manta and devil rays) are large-scale ram filter feeders that separate planktonic food particles from large volumes of water with minimal clogging. This contrasts with most human-made filters that can suffer from problematic clogging requiring additional mechanisms for clearing blocked surfaces and maintaining performance. Prior studies have shown that mobulas employ a unique mechanism referred to as ricochet separation to filter feed, whereby captive vortices in filter pores cause particles to bounce off the filter surfaces and away from the filter pores. This mechanism enables the filtration of particles smaller than the pore size and reduced clogging. However, few …

Low Salinities Impair Heat Tolerance And Alter Reproductive Traits With No Implications For Survival In A Marine Annelid From Coastal Habitats, Gabrielle Newton, Gloria Massamba-N'Siala

Biological Sciences Faculty Publications

Climate change is expected to intensify salinity and temperature fluctuations in estuarine and coastal habitats. However, the impact of salinity variation on ectotherms’ thermal tolerance remains underexplored, limiting our understanding of the interplay between these stressors. This study investigated salinity-dependent changes in life history traits (survival, growth rate, fecundity, and egg size) over a 33-day exposure to a salinity gradient (12, 17, 22, 27, 32, 35, 40, 45, 50) in the marine annelid Ophryotrocha labronica. Individuals that survived the salinity treatments were assessed for their upper and lower thermal tolerance limits. Female individuals, the target of the study, exhibited …


The Prize Biter Of Modernity? Investigating Killer Whale Bite Mechanics, Daniel Hong Jan 2025

The Prize Biter Of Modernity? Investigating Killer Whale Bite Mechanics, Daniel Hong

West Chester University Graduate Theses, Dissertations, and Final Projects

Although the killer whale (Orcinus orca) is a cosmopolitan apex predator, very little work has been done on its feeding biomechanics. Here I use finite element analysis to investigate the mandibular stiffness of a juvenile male Bigg’s killer whale, and compare it to that of the false killer whale (Pseudorca crassidens) and the saltwater crocodile (Crocodylus porosus). Full mandibles and left and right halves of mandibles are simulated under FEA. I also estimate the total jaw muscle force produced by the Bigg’s killer whale using the dry skull method. The killer whale lacks an …


What We Owe Each Other: An Examination Of Social Exchange Theory And Public Perception Of Healthy Relationships, Sarah R. Korbich Jan 2025

What We Owe Each Other: An Examination Of Social Exchange Theory And Public Perception Of Healthy Relationships, Sarah R. Korbich

West Chester University Graduate Theses, Dissertations, and Final Projects

This study uses prior literature on social exchange theory and uses various frameworks to examine the public’s perception and comprehension of SET through examining user-generated content on TikTok. Social exchange theory is based upon the idea that when interacting with other persons, you are exchanging rewards and costs. This study was guided by two questions that explore how social exchange is generalized and understood by the public, and how well the public’s ideas of positively contributing to a healthy relationship aligns with operational measures of SET. This study’s intention is to encourage SET’s usage in application to relational contexts as …

Wastewater receives per- and polyfluoroalkyl substances (PFAS) from diverse consumer and industrial sources, and discharges are known to be a concern for drinking water quality. The PFAS family includes thousands of potential chemical structures containing organofluorine moieties. Exposures to a few well-studied PFAS, mainly perfluoroalkyl acids (PFAA), have been associated with increased risk of many adverse health outcomes, prompting federal drinking water regulations for six compounds in 2024. Here, we find that the six regulated PFAS (mean = 7 to 8%) and 18 measured PFAA (mean = 11 to 21%) make up only a small fraction of the extractable organofluorine …

Measuring dissolved concentrations of polybrominated diphenyl ethers (PBDEs) and non-BDE flame retardants on a global scale provides critical insights into the effectiveness of the Stockholm Convention. In the present study, we deployed passive sampling devices at 43 seawater and freshwater sites covering 21 countries from 2016 to 2020. The detection frequencies were 20–94% for BDE congeners and 33–42% for dechlorane plus, higher than those (0–20%) for other target compounds. The median concentrations of dissolved Σ9PBDE (sum of BDE-28, -47, -66, -85, -99, -100, -153, -154, and -183) were 0.28 and 0.64 pg L–1 in seawater and freshwater, …


Achievements And Challenges With Equilibrium And Kinetic Passive Sampling Of Hydrophobic And Hydrophilic Organic Compounds In Surface Waters, Kees Booij, Rachel Mackie, Branislav Vrana, Rainer Lohmann, Sarit L. Kaserzon Jan 2025

Achievements And Challenges With Equilibrium And Kinetic Passive Sampling Of Hydrophobic And Hydrophilic Organic Compounds In Surface Waters, Kees Booij, Rachel Mackie, Branislav Vrana, Rainer Lohmann, Sarit L. Kaserzon

Graduate School of Oceanography Faculty Publications

Passive sampling in surface waters is an important method in the monitoring and risk assessment of hydrophobic and hydrophilic organic chemicals. Sampler designs can be optimized for fast equilibrium attainment (equilibrium sampling) or improved time-integrative capability (kinetic sampling). We argue that both equilibrium and kinetic sampling can be applied when aqueous concentrations do not vary with time, whereas kinetic sampling also yields useful results for time-variable concentrations that are often observed with hydrophilic compounds in surface waters. We show that these methods have similar accuracy in principle but that their dominant error sources are different: sampler-water sorption coefficients for equilibrium …

Mitigating Cold Start Problem Through Metadata Integration And User Preference Analysis, Prabaljit Walia

Master's Projects

Recommendation systems power the most popular platforms in the world: from content catalogs on Netflix to custom feeds on TikTok – the importance of recommendation systems is significant. Collaborative filtering, the most popular recommendation technique, is essentially based on the idea of leveraging collective user intelligence i.e., creating recommendations by finding similar users. But this technique suffers when there is not enough data in the profiles of users, formally termed as the cold start problem. This research focuses on this problem by introducing an approach that integrates metadata-driven similarity measures with profile expansion techniques. Our approach combines traditional collaborative filtering …
