Rivalry, Risk, And Ruin: The Economic Politics Of Antebellum Florida, Tyler Mudd
Rivalry, Risk, And Ruin: The Economic Politics Of Antebellum Florida, Tyler Mudd
Doctoral Dissertations and Projects
This dissertation investigates the interplay of land speculation, legal authority, and political governance in the Florida Territory from 1821 to 1845. Centered around the extensive Forbes and Innerarity land claims carried over from the Spanish period, the litigation and politics are demonstrative of the territorial administration and was profoundly shaped by a concentrated cohort. This faction of legally trained officeholders and investors, figures such as Joseph M. White, Richard K. Call, James, Gadsden, and William P. DuVal, operated as governing nucleus. Their ability and command of statutes, access to federal patronage, and strategic involvement allowed them to use land speculation, …
Sacred Space, Divine Presence, And Covenant: A Theological Trajectory From Eden To The Indwelling Spirit Across The Pentateuch And The Book Of Joshua, William C. Merry
Sacred Space, Divine Presence, And Covenant: A Theological Trajectory From Eden To The Indwelling Spirit Across The Pentateuch And The Book Of Joshua, William C. Merry
Doctoral Dissertations and Projects
This dissertation thesis is that sacred space, divine presence, and covenant are a theological triad that gives form to the canonical progression from Eden through the Pentateuch into Joshua and finds its eschatological orientation in the indwelling Spirit. The project as a whole, and its treatment of Genesis–Deuteronomy and Joshua in particular, maintains that the presence of God is never conceived independently of a covenantal relationship and is thereby always concretized, i.e., spatialized in and through the site or locale of the sacred space: Eden, the tabernacle, the land, and the sanctuary at Shiloh. Each of these stages in the …

Climate change has significantly increased the risk of drought and natural disasters. Droughts are expected to become more frequent and severe globally, particularly in Iraq, due to decreasing precipitation, rising temperatures, reduced vegetation cover, and water scarcity. The extent and location of drought are primarily influenced by limited precipitation and scarce water resources. In Iraq, drought is a serious and recurring issue exacerbated by the mismanagement of water resources and insufficient precipitation. Drought indicators are utilized to monitor and evaluate drought conditions to address this issue. Drought models typically consider systematic patterns of precipitation shortages, temperature increases, and other factors …

The behavior of subgrade materials plays a pivotal role in determining the longevity of transportation infrastructure. More often, interests had been focused on the mechanical behavior of treated soils prior to the failure stage, while the critical state conditions had received very little attention. This study focused on the critical state characteristics of two distinct lateritic soils (Sample 1, non-plastic and Sample 2, plastic) which were treated with rice husk ash (RHA). The chemical composition of the rice husk ash was examined using X-ray fluorescence. The two natural soils were characterized, and the X-ray diffraction technique was used to identify …
