The Rhetoric Of Missions Reporting, Bailey Cate

Electronic Theses and Dissertations

Missions, especially short-term trips, are becoming more and more controversial. As short-term missionaries interact in the field, they take pictures depicting the poverty, lack of resources, and overall sense of destitution around them. These photos have helped generate income, as many Christians who see the photos as part of updates on mission work they supported come to see themselves in a position of “savior” because they have resources to give to “those in need.” Evangelism is a critical component of Christianity; however, how people evangelize and how they communicate about that evangelism is equally critical. By analyzing both the church …

Climatic Range Filling Of North American Trees, Benjamin Seliger

Electronic Theses and Dissertations

Understanding the degree to which species distributions are controlled by climate is crucial for forecasting biodiversity responses to climate change. Climatic equilibrium, when species are found in all places which are climatically suitable, is a fundamental assumption of species distribution models, but there is evidence in support of climate disequilibria in species ranges. Long-lived, sessile organisms such as trees may be especially vulnerable to being outpaced by climate change, and thus prone to disequilibrium. In this dissertation, I tested the degree to which North American trees are in equilibrium with their potential climatic ranges using the ‘range filling’ metric, which …

Relativistic Corrections To Nonrelativistic Electric Dipole Transitions, Daniel Venn

Electronic Theses and Dissertations

Radiative transition probabilities for light atoms and ions are normally calculated from nonrelativistic wave functions and the electric dipole transition operator. For the nonrelativistic energies, the theory of relativistic corrections is well established in terms of the Breit interaction, but the same is not true for relativistic corrections to transition probabilities. The main focus of this work to perform high precision variational calculations for the relativistic corrections for the case of allowed electric dipole transitions, and to compare with known results for the one-electron case. The calculation involves the use of perturbation theory, using pseudostates to sum over the complete …
