Evaluation of the Effect of Supportive Services on the Success of Apprentices in a Highway Trade

Maura Kelly
This project evaluates the impact of a Bureau of Labor and Industry (BOLI) initiative that provides supportive services (i.e. child care subsidies, fuel assistance, support for overnight travel, clothing and protective equipment) to promote retention of apprentices in the highway trades. This research project specifically focuses on the Knife River apprentice program, a single employer apprentice program that trains apprentices for highway work. This will be a useful case study because the ap... Read More

Seismic Damage State Models for Oregon Bridges

Peter Dusicka
The highway transportation network relies on the health and integrity of bridges. Frequently traveled parts of Oregon are within the seismically active Pacific Northwest and many of the bridges were designed and built to lateral demands that are less than the current expectation, a deficiency caused by our growing awareness of seismic hazard and our enhanced understanding of the bridge response. Many of the bridges are vulnerable to earthquakes, which can result in not only immediate damage b... Read More
