Qoe Enhancement For Video Streaming Based On Attention U-Net Model, Iman Kadhum Abbood, Doaa Ayed Mohammed, Israa Hadi Ali, Sarah Abdul-Ridha Abed

Baghdad Science Journal

Video streaming services, including YouTube, Netflix, and Amazon, account for a large portion of global internet traffic. Therefore, the maintenance of high visual quality is very important to user satisfaction and overall Quality of Experience (QoE) for these users. However, fluctuating bandwidth often causes frame drops and motion discontinuities, resulting in visual artifacts and degraded QoE. Although existing video frame interpolation methods attempt to address these challenges, most remain limited in their ability to sustain performance under bandwidth-constrained environments. To overcome these limitations, IncepU-Net has been introduced. IncepU-Net is proposed as an enhanced U-Net architecture that integrates multi-scale inception modules …

God’S Design For Human Nature: Paul’S Biblical-Theological Use Of Creation Theology In Romans 1:18–32, Eunsoo (Daniel) Seo

Doctoral Dissertations and Projects

The world in which the Apostle Paul ministered was not a theological vacuum, but a sophisticated marketplace of competing worldviews and diverse moral frameworks. Within the specific milieu of first-century Rome, the cultural forces of Stoic philosophy, Roman imperial ideology, and pagan polytheism created an environment where complex expressions of human nature and sexuality emerged. Dominant Roman social stratifications often celebrated or normalized same-sex relations and blurred the distinctions of the created order. Paul found himself proclaiming a message of a Sovereign Creator in a society that had been conditioned for centuries to view the human nature through the lens …

Grace Within The Holiness Code, Michael B. Bowe

Doctoral Dissertations and Projects

Leviticus introduces the concept of God’s holiness—his unique, innate, and ontological otherness—and calls his people to reflect that holiness in their own lives. While scholarship has traditionally focused on Israel’s sacrificial cult practices, it has often neglected the theological trajectory of holiness within the broader canonical framework of the Torah. This dissertation seeks to reframe the Holiness Code (Leviticus 17–26) not merely as a set of ritual prescriptions, but as a theological narrative that exposes the limits of human effort and invites reflection on divine grace.

Chapter 1 surveys the history of interpretation and critiques the limitations of historical-critical and …

James Wilson And His Republic Of Happiness, Seth Ryan Hodges

Doctoral Dissertations and Projects

The following dissertation examines the political and moral philosophy of James Wilson, a signer of the Declaration of Independence and a Framers’ theorist whose synthesis of natural law, theology, and Enlightenment moral philosophy grounded what he referred to as the “Republic of Happiness.” It argues that Wilson’s concept of happiness was not rhetorical, but the structural foundation of his legal and constitutional thought. Drawing on Wilson’s Lectures on Law, revolutionary pamphlets, and convention debates, the study demonstrates that for Wilson, happiness meant moral excellence rather than pleasure or material satisfaction. The pursuit of happiness represented both a divine command and …

Genesis 1:1-11:9 Shows That Humanity Is The Object Of God's Love: A Dissertation, Donna R. Dilworth

Doctoral Dissertations and Projects

Most scholars turn to the New Testament when exploring the concept of divine love, citing passages such as John 3:16 and 1 John 4:8 to illustrate God’s sacrificial love through Christ. However, this dissertation reexamines the Primeval History of Genesis 1:1–11:9 as a foundational witness to divine love, arguing that these early chapters reveal humanity as the object of God’s enduring affection, even in the absence of the Hebrew term ʾāhāḇ (“love”). Rather than focusing solely on the term “love,” it is crucial to consider the nature of God himself. Scholars widely agree that the assertion “God is love” (1 …

The Necessity Of Human Taphonomy Facilities, Mia Frame

Themis: Research Journal of Justice Studies and Forensic Science

This review explores the question of whether human taphonomy facilities (HTFs) are necessary for forensic science research. These facilities are used for multiple facets of research including postmortem interval (PMI) estimation or time since death, entomology, taphonomy, and the study of volatile organic compounds. The use of human analogues like pigs and rabbits will also be addressed to show why taphonomic research on human remains must be done. It is important to look at the physical and logistical limitations of these facilities, as well as ethical limitations including religious beliefs and public perception. This article will conclude by examining future …

When Qtc Shrinks After Rhythm Conversion, Mohammed Hussein Kamareddine, Alyssa Zakala, Farid Farkouh, Ibrahim Alameh, Gan-Xin Yan

Department of Medicine Faculty Papers

CASE SUMMARY: An 83-year-old man with a history of atrial fibrillation on amiodarone therapy was admitted for direct-current cardioversion because of recurrent atrial fibrillation with a ventricular rate of approximately 105 beats per minute. Cardioversion successfully restored sinus rhythm. Postcardioversion 12-lead electrocardiography revealed an unexpectedly short QTc of 344 ms despite chronic treatment with a QT-prolonging agent. This finding was attributed to QT hysteresis, reflecting delayed adaptation of ventricular repolarization to the abrupt reduction in heart rate after rhythm conversion.

TAKE-HOME MESSAGE: QT hysteresis can result in transient QTc shortening and has important implications for interpretation of QT intervals during …

Occupational Identity And The Interactions Of Perceptions Pertaining To Career Choice Satisfaction And Intrinsic Job Satisfaction, Barbara Denisi Etterle

Doctoral Dissertations and Projects

Individuals are often remembered not solely for who they are but also for what they do. Grounded in identity theory, social identity theory, and informed biblical theology, this study advanced the premise that occupation serves as the most salient expression of identity and purpose. The construct of work–life purpose, defined as the alignment between an individual’s occupational pursuits and overarching life purpose, was introduced. This study examined the relationships among occupational identity; career choice satisfaction; intrinsic job satisfaction; and self-perception, others-perception, and divine-perception. Using bivariate correlations and regression analyses, the results revealed significant correlations among constructs, but the predictive power …

The Perceived Vocal Health Of Male Elementary Music Educators In Maryland, Adam Samuel Beres

Doctoral Dissertations and Projects

There is a notable lack of research and expertise on the vocal well-being of music educators. Vocal health issues, even among accomplished vocalists with extensive vocal training, have highlighted a notable lack of literature on the subject. Nowhere is this issue more apparent than among male elementary music educators. Significantly, vocal-range similarities between female elementary music educators and their students place male educators at a performance disadvantage, which may encourage male music educators to adopt unhealthy vocal practices, such as prolonged use of falsetto. This study aims to investigate the impact of vocal health pedagogy on male elementary general music …

The central research question was: …

Covenantal Allegiance In The Epistle Of James: An Integrative Critical-Covenantal Interpretation, Lorpu Davis

Doctoral Dissertations and Projects

This dissertation argues that the Epistle of James presents faith as covenantal allegiance enacted through communal practices under social and theological pressure. While scholarship on James has frequently separated socio-historical analysis from theological interpretation, this study proposes an integrative reading through the Integrative Critical-Covenantal Method (ICCM). ICCM employs a three-step procedure comprising close textual analysis, text-triggered socio-historical diagnosis, and theological analysis, with integrated adjudication. The dissertation examines seven strategically selected “pressure texts” in James: 1:9–11; 1:27; 2:1–13; 2:14–26; 3:13–18; 4:1–10; and 5:1–6. These passages reveal how James addresses status competition, patronage expectations, economic vulnerability, partiality, rivalry, and injustice within diaspora …

The Problem Of Evil: Theodicy Of Afterlife, Christian C. Anyanwueze

Doctoral Dissertations and Projects

The problem of evil has remained a central issue in philosophical theology, prompting both ancient and contemporary scholars to propose various theodicies and defenses concerning the existence of evil in a world created by an omnipotent, omniscient, and wholly good God. While Plantinga’s Free Will Defense, Hick’s soul-making theodicy, and the Augustinian-Thomistic greater-good tradition offer significant contributions to the discussion, each faces important limitations. Plantinga’s model functions primarily as a logical defense and leaves unresolved questions concerning transworld depravity and eschatological fulfillment, while Hick’s instrumental use of evil as a means of soul-building has been criticized for potentially compromising divine …

Discipleship-Led, Servant Leadership: A Process For Equipping And Training Simultaneously In The Local, Revitalizing Church, Joseph Raymond Noel Smith

Doctoral Dissertations and Projects

Church revitalization has been a topic of conversation in church circles for the better part of the last two decades. While numerous books and trainings have been produced to facilitate the many necessary components of church growth required for revitalization, still more than 3400 churches close their doors annually (Rainer, 2020). Additionally, 39% of professing Christians are not currently engaged in any form of discipleship (Barna, 2022) while 45% of churches are utilizing volunteers to accomplish the work of the ministry (The Unstuck Group, 2017). These numbers indicate a substantial need within the church for a program which can simultaneously …

Harmonizing Faith: An Investigation Of The Efficacy Of A Small Group Study On The Theology Of Music For Spiritual Growth, Timothy Davis

Doctoral Dissertations and Projects

The problem this study addresses is that Trinity Anglican Church in Connersville, Indiana, had not cultivated a theology of music among its congregants to enrich encounters with God through music. The purpose of this DMIN action research project was to implement a small group study on the theology of music to enrich encounters with God through God-honoring, captivating music. The researcher employed a novel approach: Luke 10:27 served as a paradigmatic framework for exploring how music relates to the dimensions of heart (i.e., emotion), soul (i.e., spiritual encounter), strength (i.e., embodied experience), mind (i.e., intellect), and neighbor (i.e., communal and …
