Phosphorus Pathways In Deep Time
… and across the subsequent reaches of geological time. These minerals act as useful tools for probing the geological history of rocky objects, including the collisional processes through which asteroids and planets may be assembled, or indeed destroyed. However, the mechanisms by which P-bearing …

Factors Underlying Students' Conceptions of Deep Time: An Exploratory Study
ABSTRACT Geologic or “deep time” is important for understanding many geologic processes. There are two aspects to deep time. First, events in Earth’s history can be placed in temporal order on an immense time scale (succession). Second, rates of geologic processes vary significantly. Thus, some …

Deep Time: Deep Learning Extensions to Time Series Factor Analysis with Applications to Uncertainty Quantification in Economic and Financial Modeling
… uncertainty through high-order moments in time series data, along with first principal-based improvements on the standard autoencoder and variational autoencoder. While the first-principal improvements on the standard variational autoencoder provide additional means of explainability, we …

A Melting Fossil: Constituting Planetary Time In The Cryosphere, 1815-1980
… ice as a natural chronometer to understand the deep past and future of the Earth. Using archival sources that span two centuries and three continents, this project argues that through ice, Earth scientists have refashioned their conceptualization of deep time from something slow, lumbering, and …

The Evolving Face of God as Creator: Early Ninteenth-Century Traditionalist and Accommodationist Theological Responses in British Religious Thought to Paleonatural Evil in the Fossil Record
… instead suggesting a harsh concatenation of deep-time prelapsarian pain, struggle, destruction of the weak, predation, diseases, plagues, catastrophic mass extinctions, and death in the subrational creation. Thus, a new theodical dimension arose which the Church had not had to address prior …

Integrating morphological data from fossil and living species and the early evolution of ray-finned fishes (Actinopterygii)
… and genetic data. However, fossils provide a deep-time perspective on the history of life, including the tempo of evolutionary change, the acquisition of traits, and give us a glimpse at groups that have no living representatives. The goal of my dissertation is to explore problems that arise …

Fossil Poetry, theBirth of Geology, and the Romantic Imagination, 1790-1860
… communicating the dizzying, sublime notions of deep time, vanished animals, and lost worlds. This study traces the parallel development of the scientific theory of the earth and the poetry with which it was partnered, especially in the figure of its most expressive and symbolic figure: the …

Uncovering strata: an investigation into the graphic innovations of geologist Henry T. De la Beche
… also drew the first portrayal of a scene from deep time, Duria antiquior, which became the first innovative classroom geology teaching graphic. Through his introduction and development of several important genres of visual explanation, De la Beche emerged as the Father of Visual Geology …

sourdough architecture
… architecture is egocentric, where architectural time neglects the ecological deep time of geology, decay, erosion, and climate. This thesis states that, like sourdough starter, architecture arises from nature (flour and water) in the form of building materials and their physical existence, and …
