A key problem managers face is how to allocate scarce
resources among various activities or projects. Linear
programming, or LP, is a method of allocating resources
in an optimal way. It is one of the most widely used operations
research tools and has been a decision making aid in almost...
Background: Current policy in Oregon under the Individuals with Disabilities Education Act (IDEA) indicates that children diagnosed with developmental delay (DD) are eligible for services before school, but not eligible for the receipt of services in school-based programs. Due to this definition of eligibility, children with DD face additional barriers...
In the 27 years since the establishment of federal law mandating special education, no state has been fully in compliance. In addition, the voices of school personnel (special education teachers, speech and language pathologists, and school psychologists) charged with implementing these laws and regulations have been largely silent in the...

Oregon's Special Farm Use Assessment program is investigated
in this paper for its effectiveness in preserving farmland from urban

Following thermal neutron induced fission, supervised machine learning and temporal gamma-ray spectroscopy methods were used to identify differences in the delayed gamma-ray spectra of Pu-239 and U-235. The temporal gamma-ray spectroscopy method takes advantage of the time-dependent decay of fission products. Employing Spearman's rank-order correlation coefficient and without prior knowledge...

More women than ever before survive breast cancer with 89% of those diagnosed becoming survivors (NCI, 2008). However, according to the National Cancer Institute (2005) some groups of women bear a greater burden of difficulty in survivorship. Sexual minority women (SMW), or women who partner with other women in romantic...
Crops were grown at the experimental farms using accepted cultural practices (within the limits of experimentation) or trials were conducted on growers' fields. Most experiments were designed as randomized complete blocks with three to five replications. Herbicide treatments were applied uniformly with CO₂ precision plot sprayers. Unless otherwise indicated, preplant...
Results from vegetation management trials involving horticultural crops conducted during the past year are compiled and reported by faculty members of the Oregon Agricultural Experiment Station, the Oregon State Extension Service, and colleagues who cooperated from adjacent states along with local enterprises.

In this thesis, we study the Karatsuba-Ofman Algorithm (KOA), which is a recursive multi-precision multiplication method, and improve it for certain special applications. This thesis is in two parts. In the first part, we derive an efficient algorithm from the KOA to multiply the operands having a precision of 2[superscript...

Oregon land use specialists believe that the present
definitions of farm and forest land in the state planning
goals are too broad. This results in poor quality resource
lands being as strongly protected as those of top quality.
With persistent growth pressure on rural lands, a means to

Here presented is a photographic catalogue, a key, and literature review for the 35 genera and 90 species of lepturine longhorn beetles (Cerambycidae: Lepturinae) found in the Pacific Northwest. Several nomenclatural changes, recognized by the global taxonomic community, but previously unknown to North American authors, are adopted, and one new...
A healthy nation starts with healthy citizens, and participation in sports is one of the most powerful ways to promote healthy habits for a lifetime—not only for physical fitness but also for emotional wellbeing and social cohesion.

The group of scientists that make up the Intergovernmental Panel on Climate Change found in 2007 that the warming of Earth’s climate is unequivocal and largely due to human activity. Earth’s climate has changed in the past, though the recent magnitude and pace of changes are unprecedented in human existence....

"The topic of market failure is rarely addressed in the literature. This report represents a starting point. It describes the dynamics of farmers' market startups, closures, and manager turnover. It focuses on two important resources--administrative revenue and labor--used by farmers' markets. Data for a sample of markets that failed are...
Starting in the 1960's, the demand for recreational properties nationwide experienced a great surge. [Reilly, 1973; David, 1969; Hoover, n.d.; ASPO, 1976]
A number of studies have been done of the impact of recreational subdivisions on local taxes. [Tillson, et. al. 1972; Thompson and Myrick, 1975; LeJeune, 1972; Moss and...

"Farmers' markets are valuable market channels for small farmers and important venues for the economic, nutritional, and social lives of communities. Efforts to make farmers' markets sustainable should focus on two influences on markets: external (related to public policy) and internal (related to market management). Well-crafted public policy is needed...
An estuary, unlike the open ocean, is a dynamic system that is continuously undergoing changes in its physical and chemical properties. Marked fluctuations in the levels and kinds of nutrients, temperature, and salinity are normally found in estuarine environments. These changes occur principally as a result of freshwater intrusions, tidal...
School-aged children with disabilities have difficulty in meeting current physical activity guidelines (Stanish et al., 2019). As such, there is a need for providing effective physical activity promotion programs for school-aged children with disabilities. School settings can be the right place to promote physical activity for children with disabilities because...
Most farmers’ markets lack information to make effective
changes and improvements. We have designed three
simple, low-cost methods to address the information gaps.
The first two—attendance counts and dot surveys—are
quantitative and can be used independently by markets.
The third method is the more complete Rapid Market
Assessment (RMA), which...

Irrigation scheduling is directly related to profitable onion production and sustainable agricultural practices. Research at the Oregon State University Malheur Experiment Station has demonstrated that onion yield and grade are very closely related to irrigation practices, especially the criterion used to schedule irrigations. Careful attention to irrigation scheduling can help...
