The educational environment is filled with different types of students, all with diverse learning styles. The Meyers-Briggs Type Indicator and Kolb’s Theory of Experiential Learning are generally accepted methods for determining and assessing a person’s preferred method of information processing.

Despite recent efforts to improve site safety, construction still accounts for a disproportionate injury and illness rate. According to the 2007 injury and illness data released by the National Safety Council, the construction industry has a fatality and disabling injury rate that is approximately three times higher than the all-industry...
This thesis evaluates pre-construction auditing procedures used in the United Kingdom, Australia, and New Zealand in order to help create post-construction auditing procedures for the state of Oregon. It was funded as part of the development of the Oregon Department of Transportation (ODOT) Safety Investigation Manual, and also evaluates content...
Crash rates are said to be nearly three times higher on curved sections than those on straight sections of rural roadways. As a result, advisory curve/speed signs are standard practice to mitigate these risks on sharp horizontal curves. The industry standard for determining appropriate and uniform speeds for such signs...
More than 65,000 organic chemicals are currently in commercial production with
approximately 1000 added each year. Many chemicals are released into the environment as organic mixtures derived from complex hazardous or solid wastes. Of these, more than 1000 chemicals are of environmental concern because of their production quantities, toxicity, persistence,...
Because of the increased need for sustainable construction in an ever urbanizing culture, new
sustainable drainage systems are being developed and implemented. Bioswales are becoming
an increasingly popular form of sustainable urban drainage used for parking lots and
subdivisions. But little is known regarding the effectiveness of bioswales in really...
The present highway funding system, especially fuel taxes, may become less reliable revenue sources in the future, while the transportation public agencies do not have the sufficient financial resources needed to meet the increasing traffic demand. Regarding the socio-economic impact of road privatization, a wide range of approaches and models...
Forest roads produce fine sediment with traffic during wet weather. If the forest road is connected to a stream it can be a source of turbidity and fine sediment that may be detrimental to aquatic organisms especially salmonids.
The goal of this work was to investigate turbid runoff during wet-weather...

In the United States there are currently two different options for providing safety audits to roadway projects. Traditional audits can be conducted using procedures similar to those in the United Kingdom, or those similar to Australia and New Zealand (Austroads). Another option for conducting safety audits is to use the...
