Two Essays On Leveraging Analytics To Improve Healthcare, Deepika Gopukumar
Theses and Dissertations
The healthcare cost has continued to increase over the past few years despite various policies, efforts, and initiatives taken by the government. It is still projected to grow over the next few years by the Centers for Medicare and Medicaid Services (CMS). Readmissions have been a major contributor to the increase in costs and have always been a contributing factor. To get a perspective, considering the fact that at least 9% of individuals who had COVID-19 were likely to get readmitted shortly, according to a study by the Centers for Disease Control and Prevention (CDC) COVID-19 response team, along with …
An Internatural Communication Study Of Identity Within Nonprofit Animal Shelters, Samentha Emily Sepúlveda
An Internatural Communication Study Of Identity Within Nonprofit Animal Shelters, Samentha Emily Sepúlveda
Theses and Dissertations
In a two-part study of this dissertation project, I relied on qualitative research methods to examine the stories of animal shelter employees and volunteers—stories about animal shelters, animal sheltering, and shelter animals—to analyze communication processes that shape staff-identity, organizational-identity, and organizational identification. This project was guided by the communicative constitution of organizations (CCO) approach, which frames communication as not simply something that happens within an organization, but rather argues organization happens in communication. Furthermore, contributing to internatural communication research, this project explored identity and identification from a “more-than human” perspective. Relating CCO and internatural communication to research in this dissertation …

An Examination Into Retention Behavior Of Air Force Female Officers, Jessica M. Astudillo
Theses and Dissertations
Female retention rates in the US military have been considerably lower than that of their male counterparts for numerous years. In the Air Force, women represent 14 percent of officer ranks from O-5 level and above. Comparatively, the overall rate of women officers in service is 20 percent. Understanding the negative factors associated with the attrition rate of this group can help the Air Force leverage positive change. It may also influence adjustments that will increase the number of women serving, and improve diversity throughout both the officer and enlisted ranks. In this study, logistic regression and survival analysis are …

An Examination Of Civilian Retention In The United States Air Force, William F. Wilson
Theses and Dissertations
The backbone of the United States Air Force is undoubtedly the large civilian workforce that supplements the great work that is accomplished. Many research studies have been conducted on officer and enlisted personnel to ensure that the career fields are properly developed and managed to meet the ever growing demands of the military's varied missions, but no recent studies have focused on the civilian workforce. Striking a balance between new and experienced employees is paramount to success given the ever-changing economic and political landscapes where we find ourselves. The first part of the research uses logistic regression to determine the …
An Analysis Of The Effects Of Technology Readiness Levels On Cost Growth, Christopher R. Bissing
An Analysis Of The Effects Of Technology Readiness Levels On Cost Growth, Christopher R. Bissing
Theses and Dissertations
This research seeks to evaluate the effects of Technology Readiness Levels (TRL) on Cost Growth. It makes use of data from Technology Readiness Assessments (TRA) and Selected Acquisition Reports (SAR) to explore relationships between TRLs at Milestone B and cost growth in Major Defense Acquisition Programs (MDAP) and Major Automated Information Systems (MAIS). Programs using higher proportions of critical technologies rated below TRL 7 tend to experience greater cost growth than programs that use more mature technologies. Current DoD doctrine requires TRL 6 to enter Milestone B. The results of this research seek to evaluate the merit of this requirement. …
