Blessed Is Anyone Who Will Eat Bread In The Kingdom Of God: Reading The Lukan Meal-Scenes As Proleptic Messianic Banquets Signaling The Dawn Of The End Of Exile, Brian Spencer Kelly

Theses and Dissertations

Scholars frequently claim that there existed an expectation for an eschatological/ messianic banquet in Second Temple Judaism, that the banquet was used as an image for the blessed age to come, and that Jesus’ praxis of banqueting with reputed sinners related to the messianic banquet tradition. These three claims are often assumed, resulting in three problematic trends: evidence for the messianic banquet tradition is often lacking, the tradition is typically treated in isolation from other eschatological expectations, and the tradition’s connection to Jesus’ fellowship is inadequately demonstrated. This thesis begins by surveying the gamut of Second Temple literature for the …

Purpose-Driven Curriculum For 9th-12th Grades For Adulthood Careers & Life Gratification, Destiny Krystle Chioma Nnadozie

Theses and Dissertations

A purpose-driven or purpose-based curriculum is not the standard required for high schools in the United States. Students in grades 9th-12th are educated based on a curriculum that covers mathematics, English, science, and social studies (De Roux & Riehl, 2022; Xiao et al., 2018). The unique individual purpose of each student, realized while in high school, is not considered a priority, leaving students to enter their adult careers lacking true career fulfillment due to this misalignment (Baroudi et al., 2017; S. Lyons et al., 2015; H. Wu, 2024).  Using a qualitative systematic review research design, this study aimed to explore …

Employee Perception Of Manager Listening Behaviors And The Impacts On The Supervisor-Subordinate Relationship, Esther Song

Theses and Dissertations

Strong communications skills are one of the most coveted capabilities in the workplace today. Within two-way communication, listening is often overlooked as a critical skill. While there have been many theories and skill-based training around listening, it is difficult to find a consistent, global definition to listening. This lack of definition makes is challenging to assess what “good” listening skill entails. Moreover, this lack of definition creates a gap in understanding effective measures for listening in the workplace, particularly in assessing the supervisor/subordinate relationship. This study focused on understanding listening in the workplace. In particular, this study looked at employee …

Resilience And Stress: Trauma, Grit, Resilience And Perceived Organizational Support In First Responders, Paige Gallas Parker

Theses and Dissertations

First responders comprise an underserved and under-researched population, despite consensus that their work involves exposure to potentially traumatic events. Inconsistent definitions of “first responder” and unclear prevalence rates of posttraumatic stress symptoms (PTSS) limit efforts to assess and promote resilience. This study examined the relationships between grit, resilience, perceived organizational support, and trauma symptoms in a sample of 234 first responders (69% firefighters, 29% lifeguards) employed by a large West Coast fire department. Measures included a demographics questionnaire, the Professional Exposure to Traumatic Events (PETE), the Posttraumatic Stress Disorder Checklist (PCL-5), the Connor-Davidson Resilience Scale (CD-RISC-10), the Short Grit Scale …

Taking It To The Streets: A Comparative Case Study Of Urban Street Medicine Programs For The Unhoused Population, Dolly Dimple Harris

Theses and Dissertations

“Taking it to the Streets” originated from the 1960s social and political activism (Doohan & Mishori, 2019). The term reflects the 1990s movement when a Philadelphia physician decided that caring for the unhoused population was necessary and started street medicine. Street medicine is an alternative medical approach to formal healthcare intended to address unhoused individuals in their lived environment. In the street medicine model, healthcare providers offer medical support for the unhoused in alleyways, parks, under bridges, and encampments. The purpose of this comparative case study was to examine two street medicine programs’ administrative processes and how they provide healthcare …

Educating Outdoors: A Qualitative Case Study On School Readiness Development In A Nature-Based Preschool, Lauren Lefevre

Theses and Dissertations

Play is widely considered one of the most crucial activities for healthy early childhood development, yet many current early childhood education (ECE) programs prioritize academics at the expense of this critical activity. Despite this focus on math and literacy skills, a significant number of children arrive at kindergarten unable to demonstrate proper school readiness. Nature-based early childhood education (NbECE) is a growing alternative education option that prioritizes risky play, loose parts play, and nature play, potentially providing children with countless opportunities for school-readiness development through play. Guided by the biophilia hypothesis (Wilson, 1984), which suggests that humans are innately drawn …

Ai: A Path Forward In Education - Teachers’ Insights On Implementation, Challenges, And Future Innovations, Mercedes Cordoba Meeks

Proactive Distributed Emergency Response With Heterogeneous Tasks Allocation, Justice Darko, Hyoshin Park

Engineering Management & Systems Engineering Faculty Publications

Traditionally, traffic incident management (TIM) programs coordinate the deployment of emergency resources to immediate incident requests without accommodating the interdependencies on incident evolutions in the environment. However, ignoring these inherent interdependencies while making current deployment decisions is shortsighted, and the resulting naive deployment strategy can significantly worsen the overall incident delay impact on the network. The interdependencies on incident evolution in the environment, including those between incident occurrences and those between resource availability in near-future requests and the anticipated duration of the immediate incident request, should be considered through a look-ahead model when making current-stage deployment decisions. This study develops …
