This research investigated the effect of a literature-based unit on subjects' in primary grades attitudes toward the elderly and aging. The experiment followed a pretest/posttest design; covariates derived from three separate survey portions were compared with respective postmeasure scores.
Other research on young children's attitudes toward aging suggests that ageist...
Wild turkey (Meleagris gallopavo) ecology has been examined within its native range, but knowledge of extralimital populations of Rio Grande wild turkeys (M. g. intermedia) is lacking. I investigated habitat use, characteristics of activity sites, home
ranges and movements, productivity, and survival of Rio Grande turkey hens from 1989
through...
Size and color are important visual quantity attributes of the fruit of strawberry (Fmgaria x ananassa Duch.). Strawberry cultivars produce fruit of a characteristic size and color, the later being the result of accumulation of particular anthocyanins. This research sought to determine the basis for genotypic differences in fruit size...
The Rattlesnake Ash-Flow Tuff erupted 7.05±0.01 Ma from the western Harney Basin, southeastern Oregon. The location of the vent area is inferred based on vent-ward increases in size of pumices, in degree of welding, and in degree of post-emplacement crystallization. Today's outcrops cover 9000 km2 and estimated original outcrop coverage...
I evaluated fire occurrence, growth and recruitment and determined the fire history of 21 old and 20 young 8ha stands in Cascade, Siskiyou and mid-Coast mixed conifer and evergreen forests in southwestern Oregon. The rates and patterns of growth were measured and analyzed on 1,079 old-growth and 2,111
young stand...
The main result of this written dissertation is a mathematical solution to the problem of multiplex recording for high performance tandem time-of-flight mass spectrometry. The prescription is to use a time-lag accelerator in the second stage to match the ion optical properties of the decay fragments to the requirements of...
The primary purpose of this study was to determine the work values of the emotionally disturbed adolescents and to compare these values with those indicated by adolescents
of the same age level from a regular public school. A secondary objective was to compare the work values of the age levels,...
The dissertation introduces community-based adaptive watershed management (CAWM) as a holistic conservation framework. The CAWM
framework integrates social and ecological suitability to achieve conservation outcomes. The core theoretical concepts consist of adaptive management, adoption-diffusion,
symbolic interactionism, community-based conservation, spatial analysis and watershed management. The CAWM framework is applied to the...
This research sought to "get at" students' understandings of their own racial identity development. The limited degree with which participants have been heard and honored in research activities points to the need to inquire about their experiences first-hand, respect their stories, and consider their voices among, or in spite of,...
The purpose of this study was to provide understanding of Oregon Workforce Quality Council contributions to the development of a world-class workforce. Research goals were
to describe Council processes and outcomes, as well as barriers to the achievement of Council purposes. A case-study approach was selected for the research design....
Instruction in a University Honors College was evaluated using Small Group Instructional Diagnosis (SGID), a qualitative evaluation process. Fifty-one class sections were evaluated over a three-year period to determine what worked to help students learn, what did not work, and suggestions for improvement. Seven instructors used both SGID and an...
The role of synthesis and degradation in controlling enzyme
concentrations was studied.
Concentrations of chloride and arginine were determined for
blood and liver at various stages of development from the embryo to
the 8 day old chicken. The chloride concentrations were used to
obtain the volume of extracellular blood in...
Epiphytic, planktonic and benthic diatom assemblages were investigated in Netarts Bay, Oregon. Samples were collected for a
one-year period from February 1980 to March 1981. A planktonic flora was observed only during periods of offshore enrichment when marine neritic species were abundant and were transported into the bay by tidal...
The purpose of this study was to determine if there was a difference in students' drinking patterns and the resultant negative consequences based on gender role identity,
gender role ideology and self-reported drinking motivations on a college campus. A
questionnaire was administered to a sample of 735 university students. Gender...
The purpose of this study was to determine the extent to which an Immersion Bilingual Mathematics Institute (IBMI) can affect the mathematics achievement of entering seventh grade students of Mexican-American heritage. Mathematics achievement was defined as
mathematics skills measured by the Mathematics Computation and Mathematics Concepts and Applications tests of...
An investigation has been made of several physical parameters of the effluent plume of the Columbia River as it enters the Pacific
Ocean. Radioactive material in trace amounts enters the Columbia River from the Hanford nuclear reactors at Richland, Washington. One of these nuclides, chromium -51, has been used to...
In juvenile corrections education approximately 50% of the students are eligible for special education services. This dissertation examines Oregon's juvenile corrections educators' understanding of their role in the special education process. This process involves student referrals, evaluations, and eligibility determination for special education services, and the development of individualized education...
The eruption of Mt. St. Helens provided the
opportunity to study secondary production of grazing insects in the context of disturbance. Two stream sites were chosen that significantly differed in how their
watersheds were impacted by the eruption. Clearwater Creek was catastrophically disturbed (physical alteration of habitat, loss of riparian...
The primary purpose of the present study was to investigate the effect of peer presence upon the health-related physical fitness test scores of college students. A total of 312 undergraduate college students, 156 males and 156 females, 18 through 29 years of age, randomly selected from the physical education activity...
Due to its frequent use in agriculture and its frequent detection in surface water,
atrazine was chosen as a model compound to study the treatment capability of a surface flow wetland used to remediate irrigation runoff at a container nursery near Portland, Oregon. Further evaluation of treatment of atrazine was...
