Talk Like An Egyptian: Egyptian Influence And Appropriation In The Book Of Exodus, Dorian W. Alexander

Dissertations

Problem

It is an inarguable truth that ancient Egypt has left a legacy upon world culture. However, the one area of Egyptian influence and legacy that remains to be studied in greater scholarship is the Bible. While many have made observations in effort to detract from and even outrightly refute any Egyptian influence on the Bible, one merely need read through any number of passages in the Bible (particularly the Old Testament) to witness just how large of an imprint is made upon it by ancient Egypt.

Method

Within just the limits of the book of Exodus alone, one finds …

Refining Cross-Population Polygenic Risk Scores Across Diverse Populations, Mansi Patel

Dissertations

Large biobanks containing whole genome sequences connected to the deidentified electronic health records of hundreds of thousands of individuals are increasingly available to researchers. This has facilitated the development of polygenic risk scores (PRS), which use machine learning to predict risk of disease and other phenotypes from millions of genetic variants. Due to Eurocentricity of available genetic data, PRS have primarily been trained in populations of European descent. Differences in allele frequencies, effect sizes, and linkage disequilibrium patterns between populations can limit the transferability of PRS across different populations. Given that most data are from European genetic ancestry populations, we …

Investigating Whether Txnrd2 Is A Therapeutic Target Against Triple Negative Breast Cancer Using African American-Derived Models, Keacha Chang

Dissertations

Despite similar breast cancer incidence rates, African American (AA) women experience a 40% higher mortality rate compared to Caucasian American (CA) women. This disparity is multifactorial and particularly pronounced in the Chicago area.

Soteriological Perspectives In The Seventh-Day Adventist Church From 1930 To 2000, Jungkyu Park

Dissertations

The Topic

The soteriology of the Seventh-day Adventist Church, originally shaped in the mid-nineteenth century around the preparation for the imminent Second Coming, has undergone gradual development over time. By the mid-twentieth century, various perspectives emerged due to the continuation of traditional teachings from the late nineteenth century and challenges from external theological influences. In particular, throughout the debate over Last Generation Theology, each theologian defined and interpreted “righteousness by faith” according to their own theological background and historical context. The resulting tensions and conflicts continue to persist to this day.

The Purpose

This study aims to describe and examine …

Comparison Of Post-Exercise Lipid Oxidation Rates Between Lower And 1 Upper-Body Resistance Training In Well-Trained Females, Alyssa L. Parten

Dissertations

INTRODUCTION: Lipid oxidation (LOx) is a relevant physiological process linked to metabolic health. Despite growing interest in resistance training (RT) as a means to influence substrate utilization LOx responses in females remain poorly characterized, with no study examining whether lower- and upper body RT elicits different LOx patterns during the recovery period following exercise. This distinction may  be relevant because lower-body exercises involves greater fat-free mass (FFM) and energy expenditure,  whereas upper-body exercises recruit less FFM, potentially influencing metabolic effects.

PURPOSE: To  determine if LOx rates after exercise differ between lower- and upper-body RT in well-trained females.

METHODS: Twenty-two females …

What About The Children? An Exploration Of Family Counselors' Play Therapy Training And Preparedness To Integrate Children Into Family Counseling, Patricia J. Walker Monical

Dissertations

Children are an important part of families, yet family counselor education programs often do not incorporate training for including children in family counseling. At some point in their careers, family counselors and therapists will encounter clients who have children 3–12 years old. The problem is that since these professionals often receive little to no training in play therapy and thus do not typically include young children in family therapy, these younger family members are often overlooked. Research has confirmed that, due to a lack of sufficient training and supervision in play therapy, many family therapists report feeling unprepared to work …

Alienation On Campus: Students, Agency, And A 'Praxis Of Possibility', Julia R. Allison

Dissertations

In the 1950s, 60s, and 70s, the idea of alienation took hold across the United States as a way of explaining feelings of disconnection, powerlessness, and meaninglessness that seemed to be pervading American society.
