The primary purpose of this study was to determine the effectiveness of the Oregon Level I Diversion Program in changing knowledge and attitude concerning driving after drinking. A secondary purpose was to determine the effect of the eight different class-time schedules used to teach the required 12-hour curriculum on the clients' test scores. An additional purpose was to determine if a significant correlation existed between gain in knowledge scores and selected instructional variables. The 61 Item Drinking and Driving Inventory was administered to all 965 individuals in the sample. Pretest and posttest scores were analyzed using a Paired T and Analysis of Covariance. Data from questionnaires administered to teachers in the Oregon Diversion Program were correlated with students' gains in knowledge scores. The Pearson r and Spearman rho were used in the correlation analyses. Results of the statistical analyses at the .05 level of significance were: 1. There was a significant difference in pretest and posttest scores for all four dependent variables (knowledge score, two attitude scores and the behavioral intention score). 2. There was a significant difference in the adjusted means among the eight time spans for three of the dependent variables (knowledge score, one attitude score and the behavioral intention score). 3. The instructional variable identified as Cultural Differences on the questionnaire correlated significantly with students' gains in knowledge scores. An additional finding was gathered from the Oregon Department of Motor Vehicles' statistics. There was a lower re-arrest rate for the clients who completed the Level I Diversion Program than for the persons who chose to be processed through the court system. Selected recommendations included: 1. A long range study of recidivism to include correlation of personal and demographic variables of clients should be conducted. 2. A demographic analysis of program instructors, including their educational background correlated with performance, should be undertaken. / Graduation date: 1984

I investigated the population attributes and habitat selection of mountain beaver (Aplodontia rufa) recolonizing clearcuts in the Coast Range mountains of Polk and Lincoln counties, Oregon between June 1989 and August 1990. The population characteristics of colonizing mountain beaver were evaluated in 12 stands of 3 types: 1-year-old clearcuts assumed to be inhabited entirely by immigrants, 4- to 5-year-old clearcuts inhabited by immigrants and their descendants, and 40- to 60-year-old forest stands assumed to support stable mountain beaver populations. Mountain beaver rapidly recolonized vacant habitat created by previous trapping efforts; after only 1 year, densities in clearcuts were statistically indistinguishable from forest sites (P = 0.7). Populations in 1-year-old clearcuts had more juveniles (P = 0.03) and had a female bias (P = 0.02) when compared with the predominantly adult male populations in the other two stand types. Individuals from clearcuts were heavier than those from forest sites (P < 0.05). Approximately half of the juvenile females in clearcuts reproduced; no juvenile females were found to be reproductively active in forest stands. Among juvenile females that conceived, those in 1-year-old clearcuts had larger litter sizes than those in 4- to 5-year-old clearcuts (P < 0.05). The 8 clearcuts were used to identify habitat features selected by recolonizing mountain beaver. Clearcuts were colonized irrespective of distances < 400 m from edge (R² = 0.01). Six habitat variables were selected by stepwise logistic regression model colonized versus non-colonized habitat. Mountain beaver selected areas with high amounts (<25-cm) and large (>25-cm) woody debris, forage plants, and uprooted stumps; they were likely to colonize areas that had highly penetrable (soft) soils and areas near drainages. The logistic function that included these 6 variables had a correct classification rate of 85% based on a jackknife procedure. Forest managers may find these habitat features useful in predicting mountain beaver recolonization and damage. / Graduation date: 1992

The purpose of this study was to investigate how schools/school districts plan to implement Oregon Administrative Rule 581-22-413, specifically: (1) How schools plan to integrate alcohol and drug abuse prevention into the Comprehensive Health Program. (2) How schools plan for age appropriate annual instruction at the senior high level. (3) How schools plan for the alcohol and drug abuse prevention education of the district's staff. An examination of the related literature revealed concerns about the proper type of planning schools/school districts would need to do to effectively satisfy this OAR. The literature further indicated School Health Programs were encouraged by the experts in the field, but few schools had achieved the entire concept. Staff education was an area that the literature indicated needed greater definition and implementation. A survey questionnaire was prepared with the help of a Delphi group to investigate the concerns. The questionnaire was sent to 180 randomly chosen administrators. The data were collected and descriptive analyses were performed. It was determined from this study that most of the Oregon schools administrators are concerned about OAR 581-22-413 and are attempting to meet these regulations. However, they are facing time and financial constraints which make it difficult to fit the new requirements into the curriculum. Staff in-service is becoming a reality for administrators and certified staff but other school personnel have been left out. There are indications that alcohol and drug abuse prevention education is being integrated into senior high school classes such as Science, Social Studies and Physical Education, in addition to comprehensive health courses. This approach can work providing the teachers of those subjects are well prepared to teach alcohol and drug prevention effectively. It was recommended that all college graduates seeking a teaching certificate be required to take a course in alcohol and drug abuse prevention in order to qualify. / Graduation date: 1991

As part of a hierarchical approach to classifying watersheds and stream habitats based on geomorphic and geologic criteria, we defined ten classes of fluvial and lacustrine habitats at the scale of valley segments. Valley segments are landscape units which encompass surface waters and the adjacent floodplains and hillslopes with which they interact over time frames of thousands of years. They form a large-scale template that constrains the character of aquatic habitat, controls the effects of disturbances in riparian areas, and mediates responses of streams to upland and upstream events. The regional distribution of valley segment types in southwest Oregon reflects bedrock geology and tectonic history of the landscape. Fluvial segment types differ in stream adjacent landforms, slope erosion processes, floodplain and valley morphology, channel slope, riparian vegetation, streambank texture, gravel bar morphology, and pool-forming features. Studies that do not carefully account for inherent differences between valley segment types could fail to detect critical changes in stream habitat caused by human disturbance. Alluvial valley and alluviated canyon segment types, which have extensive floodplains, low channel slopes, abundant woody debris, and ample gravel beds, are of greatest direct importance for salmon and other native fishes. Virtually all alluvial valleys in the study area have been heavily disturbed by logging, agriculture, and residential development. Alluviated canyon segments located in the few drainage basins where human activity has been limited probably serve as habitat refugia for the last diverse assemblages and productive populations of salmon in the region. Alluviated canyons in extensively-fogged basins exhibit increased abundance of large woody debris, fewer cross-channel debris jams, more extensive bank erosion, reduced pool area and increased riffle area, shallower riffles, and increased surface concentration of fine sediments in pools and other habitats, compared to similar segments in lesser-disturbed basins. These changes in channel morphology and stability appear to be driven by increased sediment load, caused by logging-related landslides and other erosion sources. Field studies in Sixes River basin indicated that abundance and diversity of salmonid fishes declines as maximum stream temperature increases. Changes in summer distribution of juvenile chinook and coho salmon since 1970 are related to changes In water temperature. Although some tributaries have cooled, a decline in rearing distribution in mainstem areas could be caused by long-term loss of channel complexity and associated coolwater refugia. Analysis of fish habitat structures constructed by federal and state agencies indicated that failure rates are high. Recovery of anadromous fish runs in southwest Oregon will require protection of remaining habitat refugia and reduction of sediment yield from disturbed watersheds. / Graduation date: 1992

Over the past four years, considerable attention has been focused on the problems of high unemployment in the State of Oregon. The percentage of jobless continued to be higher than that of the nation. The depressed housing market, caused by high interest rates, coupled with an increase in the import of Canadian timber managed to reduce the demand for Oregon lumber and wood products drastically. This has resulted in an abnormally high unemployment rate in many of Oregon's counties which are dependent on the wood industry; for example, the 1980 jobless rate in Harney County reached a record high of 29 percent. On the other side of the spectrum, less dependent counties such as Gilliam and Morrow continued to grow during the same period, with unemployment rates of merely 4.9 and 5.8 percent respectively. These rates are approximately half the state average. Community leaders, including the Governor, seem convinced that the only solution is economic diversification. It is an argument that makes a great deal of sense at first glance. The notion here is that if you diversify you will become less vulnerable to outside forces and hence will have a more stable economy. But what is diversification? How can we tell that one region is more diversified than another? Furthermore, having a diversified economy, does this ensure a lower rate of unemployment? The thrust of this dissertation deals with providing answers to these questions. Three schools of thought--ogive-norm, portfolio variance and entropy--were examined in an effort to determine a more proper measure of economic diversification. Various statistical procedures of hypothesis testing were employed together with stepwise regression and analysis of variance. The research findings indicate that there is a definite relationship between economic diversification and regional unemployment. However, only 28 percent of the change in the rate of unemployment is explainable by changes in the levels of diversification.
