Evangelistic Preaching Essentials: Inviting The Next "Yes", Julie Ann O'Hara

Doctor of Leadership

Churches within the seventy-eight districts of the USA/Canada Region of the Church of the Nazarene do not have consistently effective evangelistic preaching. Evangelistic preaching is central to the denomination's historical identity, rooted in the holiness tradition of gospel proclamation that invites response. Educational pathways for ordination provide limited exposure to evangelistic preaching, relying instead on local-level practice, and opportunities are frequently limited. Consequently, many developing preachers enter ministry with passion but little experience in evangelistic proclamation.

Research conducted in response to the NPO highlighted several insights. First, growth in preaching requires repeated practice, not simply exposure to content. Second, practice …

Addressing Pornography Use Among Christian University Students: A Small Group Study Curriculum, Jeffery P. Styer

Doctor of Leadership

In the world of 24/7 access to the internet, it has been determined that Christian universities have students who struggle with a habit of viewing pornography impacting current and future relationships, with God, self, and others. These students graduate and are sent out into the world where they continue to struggle with pornography use and its accompanying guilt and shame. It is an injustice for the university and the church (worldwide) not to address this problem.

Research for this project confirms that pornography use is an issue both inside and outside the church. Christians are quick to identify pornography as …

Differences In Comorbidities, Presenting Symptoms, Demographics, And Patient Reported Outcomes In Long Covid By Initial Test Status, Stephanie Georgoudiou

Nursing Dissertations - Archive

Importance Severe Acute Respiratory Syndrome Coronavirus-2 (SARS-CoV-2), which causes coronavirus disease 2019 (COVID-19), remains a major global health concern. Recovery may result in persistent symptoms known as post-acute sequelae of SARS-CoV-2 (PASC), or long COVID. Most studies focus on individuals with laboratory-confirmed infection; however, some patients with COVID-like illness and negative tests also develop persistent symptoms. Testing status should not delay appropriate interventions or specialist referrals. Early, symptom-based care is essential to improve outcomes.

Objective To compare patient-reported outcomes and demographics between long COVID patients who tested positive versus negative during their initial illness.

Digital Redlining In The Smart City: Artificial Intelligence, Housing Law, And Structural Urban Inequality, Spurthi Nrusimhadevara

Undergraduate Scholarship and Creative Works

Artificial intelligence is increasingly used in urban housing systems, where it shapes decisions about tenant screening, rent pricing, lending, zoning, and neighborhood investment. Although these tools are often promoted as efficient and impartial, they frequently rely on historical data that reflect racial, economic, and spatial inequality. As a result, AI systems can reproduce discriminatory outcomes even when protected characteristics are not directly used. This paper examines digital redlining in the smart city and argues that algorithmic housing tools mirror long standing structural inequities that raise significant concerns under fair housing and civil rights law. It evaluates how automated screening, predictive …

Cultivating Trust, Communication, And Collaboration: A Relational Leadership Design For Intercultural Collaboration In Nouakchott, Mauritania, Elysse Audrey Burns

Doctor of Leadership

Foreign-led initiatives operating in Nouakchott, Mauritania, encounter challenges in collaborating effectively with local communities, hindering the growth of sustainable, locally driven leadership and contextually relevant initiatives. This doctoral project investigates how relational dynamics shape intercultural collaboration and responds through the development of a structured relational leadership certificate program grounded in the Mauritanian context.

Using documented discovery workshops and one-on-one interviews with Mauritanian and international practitioners, the research identified recurring concerns regarding decisionmaking authority, communication clarity, and the distribution of responsibility within foreignled initiatives. Participants described patterns in which expectations were inconsistently communicated, local voices were unevenly integrated into decisions, and …

Welcoming Hospitality, Adam Cheney

The project aims to invite Christians into a biblically grounded posture of hospitality toward their Somali neighbors.

Rooted in both research and lived experience, this work sits at the intersection of Evangelical ministry, support for refugees and immigrants, and community engagement. Throughout the research process, I observed the deep need for marginalized voices to be heard and understood. The study identifies four primary barriers contributing …

Added Value Of T2 Space Stir In Magnetic Resonance Imaging Evaluation Of Post-Traumatic Brachial Plexus Injury, Nehal Tharwat, Ahmed Mohamed Abdelkhalek, Mohamed Ashraf Abd El-Moniem, Hesham Abdel Fattah Elsobky, Ahmed Alaa El-Din Elagamy

Mansoura Medical Journal

Background: Traumatic brachial plexus injuries (TBPIs) cause severe upper limb disability. Owing to the complex anatomic architecture of the brachial plexus (BP), TBPIs are difficult to diagnose. Magnetic resonance neurography of the BP using three-dimensional isotropic imaging provides excellent background fat suppression and adequate soft-tissue contrast, thereby allowing better delineation of the BP along its pathway. This study aimed to compare image quality between T2-Short tau inversion recovery (T2-STIR) and 3D-transverse relaxation time-sampling perfection with application of optimized contrasts using different flip-angle evolution short tau inversion recovery (3D-T2 SPACE STIR) sequences in cases of TBPIs.

Methods: This study included 44 …

Developing Provider Digital Twins For Personalized Provider-Patient Communication Via A Rag-Based Conversational Framework, Pengze Li, Yutong Hu, Jianfu Li, Garit Gemeinhardt, Fang Li, Muhammad Amith, Licong Cui, Antonio J Forte, Cui Tao

Faculty, Staff and Student Publications

Digital twins have emerged as a paradigm in precision and personalized medicine, enabling data-driven modeling of individuals to support tailored interventions. While most existing work focuses on patient-oriented twins, little attention has been given to modeling the provider’s role, particularly in clinical communication. In this study, we present GRACE (Generalized RAG-Enhanced Conversation Framework), a framework for constructing a provider digital twin (ProDT) that emulates key aspects of clinicians’ communicative and cognitive behavior. GRACE integrates three modules: a physician-informed dialog script generation and optimization module for provider-patterned conversation, a Retrieval-Augmented Generation (RAG) pipeline for factual grounding and timely knowledge updating, and …

Intra-Coronary Imaging And Transcriptomics Of Calcified Nodules Before And After Intensive Lipid-Lowering Therapy: A Yellow Iii Substudy, Pruthvi C Revaiah, Yuliya Vengrenyuk, Jiajia Liu, Keisuke Yasumura, Vemuri Krishna Santosh, Monika Karki, Ishani Bansal, Amit Hooda, Joseph K Sweeny, Sahil Khera, Vishal Kapur, Prakash Krishnan, Pedro R Moreno, Roxana Mehran, Xiaobo Zhou, Jagat Narula, Samin K Sharma, Annapoorna S Kini

Faculty, Staff and Student Publications

Aims: Calcified nodules (CNs) contribute to 3-5% of acute coronary syndromes (ACS). Identifying peri-calcific lipid-rich areas is challenging with conventional imaging but feasible using near-infrared spectroscopy (NIRS). This YELLOW III substudy investigated the impact of maximal lipid-lowering on CN morphology and lipid content over 26 weeks.

Methods and results: Patients with stable CAD and lipid-rich, non-obstructive plaques (lipid arc >90°, FCT < 120 µm on OCT) received Evolocumab (140 mg biweekly) plus maximally tolerated statins. Lesions were evaluated at baseline and 26 weeks using combined NIRS-IVUS and OCT. Exploratory endpoints were the maximum 4 mm lipid core burden index (LCBI) in segments containing CNs (maxLCBI4mm-CN) and morphological changes in CN. Linear mixed-effects models were used to evaluate temporal changes and group interactions. Peripheral blood mononuclear cell (PBMC) transcriptomics were analysed. Among 110 patients, 43 (39.1%) had CNs. A total of 73 paired CNs were analysed for morphology, of which 65 CNs were ≥4 mm. CNs with lipid signal (CNLS) demonstrated a significant reduction in maxLCBI4mm-CN from 176.8 to 113.3 (β = -63.51 ± 17.63; P < 0.001), whereas no change was observed in dense CNs (P = 0.317). Morphological parameters remained largely unchanged in both groups. A modest increase in the surrounding calcium arc was observed in CNLS (P = 0.018), while depth showed a differential change …

A Structured Review Of Emerging Prompt Instability Indices (Piis) To Evaluate The Reproducibility Of Prompt-Driven Image Segmentation Models., Adib Shafipour, Deevakar Rogith, Zulfiia Ditto, Hien V Tran, Katie Stinson, Toufeeq Ahmed Syed

Faculty, Staff and Student Publications

Prompt-aware image segmentation has introduced new flexibility by allowing models to incorporate user-provided cues, such as points, boxes, or text prompts, to guide object delineation across diverse imaging domains. This flexibility introduces a fundamental challenge: ensuring segmentation results remain reproducible when prompts are altered. Minor variations in prompts produce substantially different outputs, raising concerns about the reliability and scientific validity of research and clinical applications. This paper conducts a structured review of emerging Prompt Instability Indices (PIIs), quantitative measures developed to assess the reproducibility of prompt-driven segmentation models. A systematic search of PubMed and arXiv (2020-2025) identified relevant studies, analyzed …

A Hybrid Vit-L/32-Maxvit-L Architecture With Adaptive Gated Fusion For Multiclass Gastrointestinal Disease Detection And Multi-Method Post-Hoc Explainability, Shahid Mohammad Ganie, Pijush Kanti Dutta Pramanik, Zhongming Zhao

Faculty, Staff and Student Publications

Introduction: Accurate detection of gastrointestinal diseases from endoscopic images remains challenging due to substantial inter-class similarity, intra-class variability, and heterogeneous lesion presentation. While convolutional neural networks (CNNs) effectively capture fine mucosal textures, their limited receptive field restricts global contextual reasoning. Conversely, transformer architectures model long-range dependencies but may underrepresent localized structural detail.

Methods: This study proposes a dual-branch hybrid transformer framework that integrates global token-level reasoning from ViT-L/32 with hierarchical spatial modeling from MaxViT-L. An adaptive gated fusion mechanism is introduced to dynamically regulate the relative contribution of local and global representations on a per-sample basis, enabling content-aware cross-scale integration. …

Global-Local Feature Fusion: A Robust Hybrid Deep Learning Model For Multiclass Brain Tumor Classification With Grad-Cam++ Interpretation, Kirti Pant, Pijush Kanti Dutta Pramanik, Shahid Mohammad Ganie, Anindita Saha, Zhongming Zhao

Faculty, Staff and Student Publications

Background: Accurate classification of brain tumors in MRI scans is critical for effective clinical decision making, yet manual assessment is labor-intensive and subject to variability. Although deep learning models, particularly CNNs and Transformers, have shown potential, each architecture alone has limitations: CNNs excel at local feature extraction but lack global context awareness, while Transformers capture global relationships but may overlook fine-grained details.

Objectives: To develop a hybrid Transfer Learning-Transformer model that integrates CNN-driven local feature modeling with Transformer-based global reasoning to enhance multi-class brain tumor classification.

Methods: The proposed workflow comprises three stages: (1) benchmarking standalone CNN (ResNet50, VGG19, ConvNeXtBase, …

Process Over Product With Labor-Based Grading, Ti Macklin, Nicole Brun-Mercer

Boise State University Publications and Presentations

Many instructors adopt a process approach to writing, assigning multiple drafts and offering feedback for revision; they nonetheless maintain that ultimately a student must receive a grade based on the instructor-determined caliber of the final product in order to maintain high academic standards. This traditional grading system can be demotivating, increase anxiety, discourage creativity and risk-taking, and unleash linguistic bias. In contrast, labor-based grading focuses on effort and improvement and can result in greater student engagement, innovation, and growth. This article explains labor-based grading, illustrates its use in an L2 first-year writing class, and suggests ways to adopt it in …

Buying Blind: Corruption Risk And The Erosion Of Oversight In Federal Ai Procurement, Jessica Tillipman

GW Law Faculty Publications & Other Works

The United States is accelerating toward a corruption crisis of its own making. In its race to rapidly acquire artificial intelligence (AI), current policy risks undermining longstanding procurement integrity safeguards. This article examines how AI increases traditional corruption risks and introduces new vulnerabilities that current oversight mechanisms are ill-equipped to address.

Recent federal AI policies have accelerated adoption while simultaneously narrowing regulatory oversight, effectively leaving “regulation by contract” as the primary—and profoundly inadequate—mechanism for embedding safeguards. The consequence of these policies is that the government is “buying blind,” acquiring AI technologies without adequate transparency, audit rights, or testing requirements. These …

Taking Stock Of Comparative Law Teaching In U.S. Legal Education, Francesca Bignami, Irene Calboli

GW Law Faculty Publications & Other Works

For over 25 years, U.S. law schools have sought to globalize their curricula, reflecting the increasing interconnectedness and international scope of legal practice. Although there have been efforts to take stock of the impact of globalization on law schools, the vast majority have focused on international law, not comparative law. This U.S. National Report, written for the International Academy of Comparative Law’s 2026 Congress, fills the knowledge gap. In summer and fall 2024, we conducted a survey that examined course offerings, requirements, and opportunities for JD students. The survey was supplemented by interviews and a literature review of law schools …

Taking Legal Pluralism Seriously: Federalism, Diversity Jurisdiction, And The Erie Doctrine, Paul S. Berman, Emma Bjeldanes

GW Law Faculty Publications & Other Works

The U.S. Supreme Court’s watershed decision in Erie Railroad Co. v. Tompkins is sometimes read to require federal judges hearing claims based on federal diversity jurisdiction to apply state law, essentially as if the case were being decided in a state court. The doctrine therefore appears to create a categorical rule disempowering federal courts from ever departing from state law, despite the Constitution’s grant of federal jurisdiction. However, as the Court’s 2026 Erie case, Berk v. Choy, makes clear, sometimes the Erie analysis is used to empower federal courts to override clear state policy choices embodied in state law simply …

Erie And The Constitution's Constraints On General Law, Anthony J. Bellia Jr., Bradford R. Clark

GW Law Faculty Publications & Other Works

The Constitution of 1787 was the instrument by which the people of the States made a partial and conditional transfer of sovereign authority to a new federal government. To preserve the States’ residual sovereignty, the Constitution established a system of conditional federal supremacy. Specifically, it made the federal government’s ability to displace of state law contingent on compliance with specific structural and procedural safeguards. The Supremacy Clause identifies only three sources of “the supreme Law of the Land”—the Constitution, laws enacted pursuant to it, and treaties made under its authority. For each of these sources of law, the Constitution specifies …

Beyond Digital Pessimism: How A Focus On Trust Can Enhance Eu Digital Law, Neil Richards, Woodrow Hartzog, Claire Boine, Lea Despotis

Faculty Scholarship

Lawmakers looking to foster technological innovation on the European market are adopting laws they hope will promote consumer trust in digital products. Their strategy can be broken down into three components. First, they aim to empower consumers to choose how much data they want to share with companies through an express consent framework. Second, they seek to avoid harms from digital products through product safety law such as adapting the Product Safety Regulation to digital products or adopting the AI Act. Third, they endeavor to prevent manipulation of consumers through digital means.

In this essay, we argue that while laudable, …

Frame: Fast Reference-Based Ancestry Makeup Estimation Tool, Pramesh Shakya, Ardalan Naseri, Degui Zhi, Shaojie Zhang

Faculty, Staff and Student Publications

Motivation: The availability of large-scale genetic data presents a unique opportunity to study the genetic ancestries of individuals, which requires an efficient and scalable method. The existing global ancestry methods are accurate, but they cannot scale to large genetic datasets. Identity-by-descent (IBD) segments are DNA segments shared by individuals such that they are inherited from a common recent ancestor without recombination. These IBD segments, which reflect co-ancestry, provide an efficient alternative for inferring genetic ancestry.

Results: We introduced a reference-based global ancestry inference method called FRAME (Fast Reference-based Ancestry Makeup Estimation). FRAME utilizes partial local ancestry information estimated through IBD …

Music Interventions For Critically Ill Patients: Evaluating Effects Of Music On Psychoemotional Symptoms In Critically Ill Patients Receiving Respiratory Support, Allyson Crighton

Honors Undergraduate Theses

Critically ill adults receiving respiratory support in intensive care units (ICUs) frequently experience psychoemotional disturbances such as agitation, anxiety, and delirium, which contribute to prolonged ventilation, increased sedative use, and adverse patient outcomes. While pharmacologic management remains standard practice, associated risks including oversedation and delirium highlight the need for safe, complementary interventions. Emerging evidence suggests that music-based interventions may offer a non-invasive, cost-effective strategy to reduce psychological or emotional distress in this vulnerable population. This integrative literature review examined the effects of music interventions, including passive music listening and structured music therapy, on agitation and related psychoemotional outcomes in critically …

Parenting Stress And Its Association With Parental Technoference: An Integrative Literature Review, Emily S. Machuca

Honors Undergraduate Theses

Introduction: Today, digital devices are a part of daily life, but can serve as a distraction that interrupts important relationships, a process referred to as technoference. In the context of parenting, device use during child interactions may reduce parental attentiveness and engagement, with potential implications for child development and behavior. Parenting stress may influence how and why parents engage with digital devices in the presence of their children. However, the association between parenting stress and parental technoference remains unclear in the current literature. This integrative literature review aimed to synthesize existing evidence examining the relationship between parenting stress and parental …

Ai Data Center Dynamic Load Effects On Current Transformer Saturation, Sergio A. Hernandez

Electrical Engineering Theses

AI data centers can produce rapid changes in electrical demand that may influence current transformer performance during faults. This study evaluates the effect of an AI data center transient on CT saturation during single line-to-ground faults using a 400 V, 60 Hz grid connected inverter model in MATLAB/Simulink. The normal condition transient produced a maximum RMS current rate of approximately 211 A/ms, which was used along with the maximum power condition to define fault inception cases. A MATLAB time-domain CT model then swept the fault current DC offset coefficient to determine the minimum offset required for CT saturation. The calculated …
