Interrupting Generational Poverty: Experiences Affecting Successful Completion Of A Bachelor's Degree, Donna Marie Beegle

Dissertations and Theses

The problem addressed in this study can be stated thus: There are extremely limited numbers of students from the lowest economic class graduating from our nation's institutions of higher education. The challenge to institutions of higher education is how to improve access, support, and successful completion of higher education for students experiencing the most extreme poverty barriers.

Weber's (1946) social-class theory was selected to determine the meanings and interpretations of students from poverty backgrounds in regard to their success and perceived barriers to success in completing college. This theoretical construct is based on the idea that collectively held meanings arise …

The Impacts Of The Introduced European Green Crab, Carcinus Maenas, On Selected Bivalves And Meiofaunal Communities, Zasha A. Bassett

Dissertations and Theses

This thesis examines the potential impact of the invasive green crab, Carcinus maenas, in Yaquina Bay, Oregon. I sampled the current extent of crab colonization in the intertidal zone of Yaquina Bay using a standardized trapping regimen in selected intertidal sites in August and September 1999. I also evaluated the potential impacts of C. maenas on the commercially important bivalve, Crassotrea gigas. Carcinus' preferred size ranges of C. gigas and other species were experimentally determined. Additionally, Carcinus species preference for C. gigas was examined in relation to two common bivalves, Mytilus trossolus and Macoma nasuta. Experiments were …

The report considers several factors that are likely to affect the school district's enrollments between the present and 2010, including the future number of births, net migrants, and the proportion of school-age children and youth enrolled in the public schools. To take into account a variety of demographic and enrollment possibilities, this report describes five different scenarios of housing, population, and enrollment changes for the ten years between 2000 to 2010.

Time Point-Level Analysis Of Passenger Demand And Transit Service Reliability, Thomas J. Kimpel, James G. Strathman, Kenneth Dueker

Center for Urban Studies Publications and Reports

This paper provides a framework for analyzing transit service reliability and estimating passenger demand at the time point-level of analysis. It begins with a literature review of passenger demand modeling and transit service reliability analysis, and shows how advances in transportation technologies are producing vast amounts of data that encourage the use of new modeling techniques. Differences between route-level and time point-level demand modeling are discussed. Lastly, the results of the passenger demand and transit service reliability models estimated from Tri-Met BDS data are presented.

A Clearinghouse Approach To Sharing Transportation Gis Data, Kenneth Dueker, J. Allison Butler, Paul Bender, Jihong Zhang

Center for Urban Studies Publications and Reports

Updating and maintaining Geographic Information Systems-Transportation data (GIS-T data) is proving difficult. Different database formats needed to support diverse applications leads to inconsistencies and inaccuracies, and duplication in updating. A clearinghouse approach is recommended for the collection and dissemination of new transportation features that can be segmented in different ways to meet the needs of various applications and inserted to update existing GIS-T databases. The clearinghouse approach is advantageous in that it is based on collecting data about new or changed transportation features once and uses the data many times to update existing databases.

An Examination Of Commercial Medicinal Plant Harvests, Mount Hood National Forest, Oregon, Shannon Michelle Campbell

Dissertations and Theses

During the past fifteen years, non-timber or special forest products have become an important economic resource in the Pacific Northwest. These products are primarily derived from understory species and contribute approximately $200 million to the regional economy. Medicinal plants are a little researched component of the non-timber forest product industry that relies on cultivated and wildcrafted (or wild-collected) medicinal plant species. This study examines the commercial extraction of wildcrafted medicinal plants from Mount Hood National Forest. Specifically, this study documents the medicinal plant species extracted from Mount Hood National Forest, their annual yield amounts, harvesting methods, and the changes in …

Cooking In Eden: Inventing Regional Cuisine In The Pacific Northwest, Amy Jo Woodruff

Dissertations and Theses

This study examines how regional cuisine is being self-consciously constructed in the Pacific Northwest and discusses the ways in which it contributes to identity in the region. I identify the characteristics--foods, dishes, and culinary practices--of this "new" Northwest cuisine, as well as social and cultural values associated with it, and explore how together they create a sense of regional distinctiveness and loyalty. Because this type of regional cuisine is closely associated with the professional cooking community, I look to restaurants in Portland, Oregon that self-identity as representative of the Pacific Northwest and to regional cookbooks, in order to pinpoint the …

“Where Girls Will Be Boys And Boys Will Be Girls”: The Spatial Perceptions And Place-Bound Identity Of The Drag Community In Portland, Oregon, Courtney Sullivan Villegas

Dissertations and Theses

Space is socially and culturally constructed. As such, experiences in and perceptions of the environment vary on the basis of culture and position in society. These perceptions influence the creation of places, especially places designed to make people feel accepted and at home. The building of such places and of community networks between these places is most important among groups who find themselves outside of societal norms.

This research examines these notions of space and place through a focus on the drag community in Portland, Oregon in order to determine whether spatial perception contributes to the construction of a place-bound …

Use Of Cultural Topics In Electronic Dialogue Journals In The Foreign Language Classroom, Katya Elizabeth Monge Jacome

Dissertations and Theses

The purpose of this study has been to determine what effect the difference in cultural and general topics has on the length, complexity, and quality of resulting entries in electronic dialogue journals. The data, which consisted of 132 electronic dialogue entries generated by eleven adult students in a second year university Spanish course over a period of four weeks, were measured for length, in terms of total words and total number of t-units; complexity, by dividing the total number of words by the total number of t-units; and quality, as assessed by the Jacobs profile (1981), which considers the following …

Asiatic Cholera And Dysentery On The Oregon Trail: A Historical Medical Geography Study, Brian Lee Altonen

Dissertations and Theses

Two disease regions existed on the Oregon Trail. Asiatic cholera impacted the Platte River flood plain from 1849 to 1852. Dysentery developed two endemic foci due to the decay of buffalo carcasses in eastern and middle Nebraska between 1844 and 1848, but later developed a much larger endemic region west of this Great Plains due to the infection of livestock carcasses by opportunistic bacteria.

This study demonstrates that whereas Asiatic cholera diffusion along the Trail was defined primarily by human population features, topography, and regional climate along the Platte River flood plain, the distribution of opportunistic dysentery along the Trail …

Signs Of Popular Ecology In The Ecotourism Landscape Near Tikal National Park, Guatemala, Michael Mooradian Lupro

Dissertations and Theses

Ecotourism is a common conservation and development strategy in the Maya, Forest region. New sites of ecotourism consumption, such as El Rematé near Tikal National Park in Guatemala, are developing in response to consumer demand for budget accommodations in this attractive cultural and natural setting. This study analyzes new ecotourism infrastructure developments in El Rematé for signs that this tourism draws on ecological imagery as expressed in popular media - or popular ecology - not on the natural and cultural ecology of the region that is the target of international conservation efforts. Analysis suggests that ecotourism entrepreneurs who effectively associate …

International Students' Experiences In Higher Education: A Case Study Examining Uncertainty Reduction Theory In Communication Classrooms, Susan Kuhn

Dissertations and Theses

This was an exploratory case study which focused on international students' experiences in higher education. In particular, this study investigated the efficacy of uncertainty reduction theory in communication classrooms. The research asked four exploratory questions: (a) What are the students’ perceptions of the teacher/student relationship? (b) Do international students experience uncertainty in communication classrooms? (c) If uncertainty is experienced, what is its source(s)? (d) If uncertainty is experienced, do students seek to reduce it, and if so, how?

A phenomenological perspective was utilized in this study as the organizing, theoretical framework. Relevant literature on uncertainty reduction theory was reviewed as …

Multiple Source Pools And Dispersal Barriers For Galápagos Plant Species Distribution, J. Alan Yeakley, John F. Weishampel

Environmental Science and Management Faculty Publications and Presentations

We reexamined geographic factors explaining the number of plant species on islands in the Galápagos Archipelago. We hypothesized that plant species richness (S) was related to the number of source pools and that plant species dispersal preferentially followed direct, oceanic pathways. To test different dispersal pathways from multiple source pools, the total number of islands within a given dispersal radius (i) was posed as the sum of the number of line-of-sight islands (C_i) and of the number of islands without line-of sight connection (B_i). In partial regression analyses, controlling for nearest island area (A₂) …

Residents Informing The Planning Process: Pleasant Valley And Its Natural Resources, Steve Olson, Ian Simpson, Jay Sugnet, Tim Williams, Alison Young

Master of Urban and Regional Planning Workshop Projects

As a society, we are slowly learning the importance of the interaction between the natural and built environments. We need a new model for planning and development that gives more weight to natural resource considerations than has traditionally occurred in the development process.

An opportunity exists in Pleasant Valley to bring focus to natural resources in future planning efforts by tapping into the local knowledge of residents who know and love the land. Because the area will begin to urbanize in the near future, it is necessary to learn about the area before development occurs or people move away. The …

Spatial Modeling In Emergency Medical Systems: Analysis Of A Regional Trauma System With Two Centers, Christopher A. Bangs

Dissertations and Theses

The allocation of trauma patients to one of two trauma centers based on multiple criteria presents significant challenges in modeling network-based solutions for Emergency Medical Services (EMS). Capabilities in a desktop Geographic Information Systems (GIS) include spatial analysis and map visualizations that contribute to improved understanding of EMS and the trauma allocation. Using a common desktop GIS application and a statistical analysis application, key spatial and temporal characteristics of both penetrating and blunt trauma are described, and the EMS allocation system is analyzed.

As a sub-group of all emergencies, trauma-system patients represent the most severely injured. Understanding the spatial-temporal distributions …

The Columbia River's Fate In The Twentieth Century, William L. Lang

History Faculty Publications and Presentations

Discusses the history of the Columbia River during the 20th century, emphasizing the image of the river as both a source of industry and an example of wild natural beauty. In 1933 the river was dammed to harness its power for hydroelectricity and control its unpredictable flooding. With the completion of the dams in the 1970's, however, came problems with the edenic vision of the river, especially with the annual salmon run. By the late 20th century, the salmon had all but disappeared, leading to an ongoing conflict between supporters of the dams and conservationists.

Variability In Winter Mass Balance Of Northern Hemisphere Glaciers And Relations With Atmospheric Circulation, Gregory J. Mccabe, Andrew G. Fountain, Mark Dyurgerov

Geography Faculty Publications and Presentations

An analysis of variability in the winter mass balance (WMB) of 22 glaciers in the Northern Hemisphere indicates two primary modes of variability that explain 46% of the variability among all glaciers. The first mode of variability characterizes WMB variability in Northern and Central Europe and the second mode primarily represents WMB variability in northwestern North America, but also is related to variability in WMB of one glacier in Europe and one in Central Asia. These two modes of WMB variability are explained by variations in mesoscale atmospheric circulation which are driving forces of variations in surface temperature and precipitation. …

Land Use And Growth Impacts From Highway Capacity Increases, Thomas W. Sanchez

Center for Urban Studies Publications and Reports

This analysis examined the historical relationship between land use changes and the location of capacity increasing highway projects in the State of Oregon from 1970 to 1990. Aerial photography for 18 cities was used to delineate the extent of urban development in each time period. A geographic information system (GIS) was used to assemble the data. Using this data, a logit regression model tested the significance of geographic variables such as proximity to highway projects, land use zoning classification, city size, and other spatial characteristics. The analytical methods used in this study incorporated a set of commonly used techniques to …

Climate, Water Navigability, And Economic Development, Andrew D. Mellinger, Jeffrey D. Sachs, John Luke Gallup

Economics Faculty Publications and Presentations

Geographic information systems (GIS) data was used on a global scale to examine the relationship between climate (ecozones), water navigability, and economic development in terms of GDP per capita. GDP per capita and the spatial density of economic activity measured as GDP per km2 are high in temperate ecozones and in regions proximate to the sea (within 100 km of the ocean or a sea-navigable waterway). Temperate ecozones proximate to the sea account for 8 percent of the world’s inhabited land area, 23 percent of the world’s population, and 53 percent of the world’s GDP. The GDP densities in temperate …
