Crisis Of Command: Shaef, Strategy, And The War In Northwest Europe, Fall 1944, Josh Glover

Doctoral Dissertations and Projects

This dissertation examines the strategic debates among the Supreme Allied Commander, U.S. General Dwight D. Eisenhower, and his subordinate commanders, British Field Marshal Bernard Montgomery and U.S. Generals Omar Bradley and George Patton, in the fall of 1944. Most historians have focused specifically on the military campaigns throughout the fall of 1944, the commanders who executed them, and the missed opportunities and failures that occurred. The question left unanswered is why the Allies missed the opportunity to end the war in 1944. To answer this, I analyzed the numerous strategic debates among these four commanders and many others that took …

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 …

Doctoral Dissertations and Projects

Developing a well-rounded musician must be the goal of every music teacher. In today’s modern educational system, assessment is a tool used to help shape the curriculum of all subjects. Music assessment must be no different. The National Core Arts Standards (NCAS) utilize anchor standards for assessment in four categories: creating, performing, responding, and connecting. Standards that fall within performing are quickly evaluated in formal and informal assessments, but other standards, such as creation, responding, and connecting, often need exploration. One needs to craft assessments to determine student understanding of performance and non-performance standards and explore development in those areas. …

The Role Of Faith In Coping With Mental Health Challenges In Late Life: A Phenomenological Study Of Religious Experience In The Aging Population, Krista Kelley

Doctoral Dissertations and Projects

Depression, anxiety, and suicidal ideation are significant concerns among older adults. These conditions are often neglected due to stigma, atypical symptom presentation, and medical comorbidities, resulting in increased healthcare utilization, heightened suicide risk, and emotional dysregulation. Psychosocially, these challenges obstruct a successful resolution of Erikson’s final stage, ego integrity versus despair, leading to dissatisfaction, regret, and reduced well-being. Although previous research has suggested a link between religious engagement and improved mental health outcomes, few studies have explored older adults’ lived experiences of faith in coping with mental health. This qualitative phenomenological study examined the experiences of 25 older adults regarding …

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