Many conventionally reinforced concrete deck girder (RCDG) bridges were built in the US during the 1950s, throughout the expansion of the Interstate System. Designs followed the AASHO standard of the time, which permitted higher shear stress in concrete and reduced detailing requirements than permitted by current specifications. Many of these...
The purpose of this study was to provide understanding of Oregon Workforce Quality Council contributions to the development of a world-class workforce. Research goals were
to describe Council processes and outcomes, as well as barriers to the achievement of Council purposes. A case-study approach was selected for the research design....
This dissertation has two objectives. The first objective is to determine where best to situate the study of mentoring (i.e. the 'making of scientists') on the landscape of the history of science and science studies. This task is accomplished by establishing mentoring studies as a link between the robust body...
Developers frequently change the type of a program element and update all its references for performance, security, concurrency, library migration, or better maintainability. Despite type changes being a common program transformation, it is the least automated and the least studied. Manually performing type changes is tedious since the programmers have...
Surface transient storage (STS) and hyporheic transient storage (HTS) have
functional significance in stream ecology and hydrology. Both provide refugia for aquatic
communities and their longer mean residence times (compared to the main flow) increase
the potential for biogeochemical reactions that can improve water quality. As STS and
HTS have...

This document provides definitions and a general overview of streams and lakes of San Juan County (SJC) and then describes impacts to these water bodies and strategies for determining widths of buffers that protect their functions. It similarly provides definitions and a general overview of SJC upland (terrestrial) habitats, describes...
There is a significant gap in academia in the field of transboundary water management of the non-sovereign entities. The objective of this master’s thesis is to work towards filling this gap.
The first part of this master’s thesis research identifies potential hydro political tension risks of the transboundary basins in...
The Yanacocha Mining District in northern Perú is considered the largest group of
high-sulfidation style epithermal gold deposits in the world. District-scale geologic mapping coupled with detailed 40Ar/39Ar geochronology, geochemistry and petrography establish the volcanic history of the area and analyze the temporal and spatial evolution of volcanism, hypogene advanced...
Urban areas currently cover a small fraction of Oregon’s landscape but will expand to accommodate an increasingly large proportion of the state’s growing population and economic activity. Residential developments on rural lands now cover more than twice the area occupied by Oregon’s urban developments and are growing rapidly. Oregon urban...
