Standing in the Way of Control : Small Farmers, Water Use, and Technology Adoption in Oregon

Creator:: Hepperly, Jody R.
Abstract:: In recent years, several interrelated forces—prolonged drought, growing populations, height-ened environmental protections, sustained agricultural use, and hydrologic alterations due to climate change—have increased pressure on water users in the Western United States, where the agricultural sector accounts for up to 90% of total water withdrawals. Technology im-provements developed since the...

A blank screen? : digital divide discourses and practices

Creator:: Powell, Jasmine
Abstract:: The existence of a “digital divide,” or inequalities of access to digital technologies among different American subpopulations, has been hotly debated and contested since the National Telecommunications and Information Administration first popularized the phrase in 1995. The purpose of this thesis is to critically examine the dominant discourses around the...

Computer and internet usage in rural clubs : are members digitally divided?

Creator:: Cassell, Christopher J.
Abstract:: Lower rates of computer adoption and usage in rural areas has been called a "digital divide." This work explores the current state of connectivity within a rural town of the Pacific Northwest with a quantitative and qualitative overview of computer usage and access within civic and activity clubs, ranging from...

An exploration of information and communication technology use on the part of Eritrean refugees in Rome, Italy

Creator:: Opas, Matthew E.
Abstract:: Thesis explores the ways in which Information and Communication Technology (ICT)use, specifically that of telephones and the Internet, impacts the lives of Eritrean refugees in Rome, Italy. Informal interviews, semi-structured interviews, and participant observation were carried out in a 'center of second reception.' Results show that information obtained through the...

Artificial means of distinguishing smooth-line map unit boundaries : an examination of Oregon soil survey maps

Creator:: Sun, Yulin
Abstract:: Soil is a complex living system with high heterogeneity, which makes locating soil map boundaries a challenge. In traditional soil survey, the placement of soil map boundaries relies largely (at least initially) on identifying the soil-forming factors of biota and topographic relief through stereo aerial photo pairs. Future soil survey...

Development of predictive mapping techniques for soil survey and salinity mapping

Creator:: Elnaggar, Abdelhamid A.
Abstract:: Conventional soil maps represent a valuable source of information about soil characteristics, however they are subjective, very expensive, and time-consuming to prepare. Also, they do not include explicit information about the conceptual mental model used in developing them nor information about their accuracy, in addition to the error associated with...

Predicting the spatial variability in soil properties using DSM across Malheur National Forest

Creator:: Seeno, Elizabeth A.
Abstract:: Soil properties may hold the key to improved predictions of soils during digital soil mapping (DSM), which has developed with a focus on environmental factors external to soil. The spatial variability in soil properties was modeled across Malheur National Forest in eastern Oregon as an approach to improve DSM. The...

Use of decision tree analysis for predictive soils mapping and implementation on the Malheur County, Oregon initial soil survey

Creator:: Hash, Sarah Jane
Abstract:: Soil surveys provide essential information for making land use and management decisions on publicly-owned lands in the semi-arid Great Basin. Soil maps produced with conventional mapping techniques are time-consuming, costly, and do not explicitly document the soil scientist's mental soil-landscape model. Predictive soils mapping using decision tree analysis (DTA) can...

Predictive mapping for the delineation of landtype association units in the Fremont National Forest, Oregon

Creator:: Malone, Melanie R.
Abstract:: Predictive Soil Mapping (PSM) has recently become an attractive method for soil scientists wishing to develop a more objective and efficient approach to mapping soils. Due to the potential PSM has for reducing the effort to produce soil maps, as well as its ability to improve the classification accuracy of...

Predictive mapping of landtype association maps in three Oregon national forests

Creator:: Peterman, Wendy L.
Abstract:: This study explores the use of predictive mapping techniques in developing Landtype Association (LTA) maps for use in natural resource management. These maps are produced for the USDA Forest Service on a regional basis at a 1:100,000 scale. The goal of this study is to develop and test a method...
