A Theory Of General Relativity, Madeleine Mae Morris

Theses and Dissertations

"A Theory of General Relativity" is a quiet exploration into the poetic and scientific ways we inhabit space and time. This work is a manifestation of the time I spent being my grandmother's caretaker and exists now in the form of an artist book, an exhibition of framed photographs with glass objects, and this written thesis. Throughout those five years, I became consumed by the relationships between Mothers and Daughters, which brought into excruciatingly sharp focus seemingly simple questions like: who are we, what have we done to each other, what do we owe to each other, do I reap …

Machine Learning Models To Automate Radiotherapy Structure Name Standardization, Priyankar Bose

Theses and Dissertations

Structure name standardization is a critical problem in Radiotherapy planning systems to correctly identify the various Organs-at-Risk, Planning Target Volumes and `Other' organs for monitoring present and future medications. Physicians often label anatomical structure sets in Digital Imaging and Communications in Medicine (DICOM) images with nonstandard random names. Hence, the standardization of these names for the Organs at Risk (OARs), Planning Target Volumes (PTVs), and `Other' organs is a vital problem. Prior works considered traditional machine learning approaches on structure sets with moderate success. We compare both traditional methods and deep neural network-based approaches on the multimodal vision-language prostate cancer …

The Experiences Of Parents In A Christian Spiritual Parenting Program, Zili Wang

Theses and Dissertations

Christians face a rising problem in faith transmission to the next generation (Kinnaman & Hawkins, 2016). Research indicates that younger generations are less religious than their parents in many countries, especially in the U.S. (Pew Research Center, 2018b). Even though most American Christians say that faith is vital in their life, educating children in religion is critical because it provides moral guidance and appropriate values (American Enterprise Institute, 2019). However, most Christians find it challenging to perceive and articulate the relationship between faith and daily life even though they attend church regularly (Bunge, 2008). Also, many parent-child spiritual programs organized …

An Examination Of Leading Through Change Using Snyder’S Hope Theory And Lewin’S 3-Step Model, Scott E. Sorensen

Theses and Dissertations

Never has the world experienced such rapid change, and the environment in which organizations operate necessitates increased change capability and organizational agility (Argyris, 1991). Strebel (1996) found success rates for change initiatives in Fortune 1000 companies ranged from a low of 20% to a high of 50%. Later studies would substantiate Strebel’s (1996) findings, claiming that, on average, failure rates of transformational change initiatives approach 70% (Beer & Nohria, 2000; Sirkin et al., 2005). Suppose this is so, and companies wish to thrive in such a dynamic environment. A fundamental understanding of why change efforts fail and how to drive …
