There is little, if any, direct fossil evidence of the cardiovascular, respiratory, reproductive or digestive biology of dinosaurs. However, a variety of data can be used to draw reasonable inferences about the physiology of the carnivorous theropod dinosaurs (Archosauria: Theropoda). Extant archosaurs, birds and crocodilians, possess regionally differentiated, vascularized and...
Providing transformational learning opportunities for undergraduate students demands changes to teaching practices. In large-enrollment introductory courses, graduate teaching assistants (GTAs) play an important role in facilitating student learning in small group environments. However GTAs are not provided the pedagogical development necessary to support them to be effective in their teaching...
This dissertation presents an analysis of the historic preservation
framework on tribal cultural resources management (CRM). It examines some of
the challenges this framework poses to tribal governments working on cultural
resources protection efforts within a compliance framework. An examination of
five major laws that regulate the practice of CRM...

This dissertation presents an analysis of the historic preservation
There is a national interest in improving the quality of science, technology, engineering, and mathematics (STEM) education in institutions of higher education in the face of mounting difficulties. Reports by the National Academy of Sciences in 2018 and 2020 found that the dissemination and adoption of effective, timely change initiatives...
Environmental archives provide records of natural and anthropogenic variation in the environment at different temporal and spatial scales. Lead (Pb) concentrations and isotopic ratios are useful tracers of anthropogenic emissions from industrial activities including mining, smelting, and leaded gasoline use, however, methods of measuring Pb are largely limited in low...
The purpose of this pilot study was to determine whether students
using a series of planned exercises designed to improve typewriter
composition skills would be better able to compose at the typewriter
than students in a control group. The study was also concerned with
the effect that the use of...
The basaltic landscapes of the Oregon High Cascades form a natural laboratory for examining how geologic setting and history influence groundwater flowpaths, streamflow sensitivity to climate, and landscape evolution. In the High Cascades, highly permeable young basaltic lavas form extensive aquifers. These aquifers are the dominant sources of summer streamflow...
