An attempt was made to demonstrate isozymic forms of esterase,
MDH, LDH and GPDH and the variation in enzyme pattern with increasing
age in the thoracic muscle, appendage muscle and hemolymph
of the American cockroach, Periplaneta americana. Sampled specimens
of both sexes were aged one through seven days, two weeks...
The Macrocheles glaber species group contains many
of the common mites which are associated with the dung
of domestic animals. Species in the glaber group have
been investigated for their use as biological control
agents of synanthropic flies.
Over 10,000 slide-mounted specimens of Macrocheles
in the OSU Acarology Collection and...
Purpose: The study assessed the perceived need for inservice
training to improve the teaching of mathematics in primary schools
in Bendel State of Nigeria. Specifically, the study sought to
know where and when the primary school mathematics teachers need
inservice training to improve their standards of teaching elementary
mathematics. The...
The purpose of this study was to seek evidence which might
lead to the development of more effective ways of dealing with the
problem of failure to attend school.
Concept of self has long been considered worthy of consideration
in evaluating behavior. It is known that significant experiences
in life...
The purpose of the study was to determine whether taking a
course of study about ethnic minorities and racial prejudice in the
United States would produce a statistically significant change in the
attitudes of white, middle-class high school students toward three
ethnic minorities i. e., Blacks, Native Americans, and Chicanos....
Studies in other laboratories have established the presence of
the Embden-Meyerhof-Parnas (EMP) pathway and the pentose phosphate
(PP) pathway in plant tissue. Research in this laboratory with mung
bean (Phaseolus aureus) seedlings has confirmed the presence of these
two pathways as well as the glucuronic acid (GA) pathway. However,
no...
The purpose of the project was to demonstrate, evaluate, and quantify the effectiveness of Best Management Practices (BMP's) adopted in 1978 (2) by Gilliam, Morrow, Sherman, Umatilla, and Wasco County Soil and Water Conservation Districts
(SWCD's), Oregon (Map 1). These demonstrations and evaluations were designed to reduce landowner uncertainties concerning...
The structure of two oak woodland types in the Santa Rosa region
of the Santa Ana Mountains of southern California has been described
by Zuill (1967). One type called the grass oak woodland (GOW) is
composed mainly of Q. engelmannii on hills and slopes. The other
type called the dense...
The purpose of this study was to compare the performance
between high school students with esteem needs and those with
security needs in discovering a two-second delay between correct
response and feedback in a paired-associated learning task, Subjects
had to determine which one of seven possible responses (digits) to a...
Modern agricultural erosion was studied using ¹³⁷Cs from
fallout as an indicator of erosion/deposition. The study area was a
285 ha agricultural watershed in the hilly western margin of the
Willamette Valley, a high winter rainfall zone in which fall-planted
crops are commonly grown.
Objectives of the study were (i)...
A study of the relative rates of the alkyl hydrogen abstraction
from a series of meta and para substituted t-butylbenzenes by the
chlorine atom at 70°C has been carried out. Application of the
Hammett equation yielded a ρ value of -0.44 for the para compounds.
Possible explanations for the non-linearity...
This investigation was initiated in an attempt to delineate
some factors affecting the adsorption of poliovirus to soil particles
in seawater. The results could have significance in the development
of assay procedures for viral contaminants in natural waters.
A sample of marine sediment, obtained from an estuary near
Purdy, Washington,...
The rise of social networking is more prevalent in today's society than ever before. Of the existing social networking platforms, Twitter is widely recognized as operating within the social networking elite. With this rise in social networking comes the challenge to develop new strategies of navigation when presenting one's identity...
About 7,000 years ago two major tephra-falls blanketed the
Pacific Northwest in volcanic ash. These two tephra-falls, identified
as the Llao and climatic tephra-falls, were a part of the eruptive
events that led up to the collapse of Mount Mazama to form Crater Lake
in the southern Oregon Cascades.
The...
Restoration programs effectively prevent or mitigate wildfires and pest outbreaks in the forest lands. The most common approach is to selectively harvest smaller and dead trees in order to preserve larger and superior trees. Ponderosa pine, Pinus ponderosa, (PP) lumber is one of the common species harvested from restoration programs...
Purpose of the Study The purpose of this investigation was two fold: (1) to determine the effects of a Summer Institute for Cultural Awareness upon the self-actualization of experienced teachers from four separate high schools, and (2) to determine the success of the Summer Institute for Cultural Awareness in terms...
Adults and nymphs of a new genus and species of the family Macrochelidae are described from detritus cavities of the leafcutting ant, Atta texana. This new species is notable in having peritremes with no posterior loop, a series of small subterminal teeth on the fixed cheliceral digit rather than the...
Seal Rock (35LNC14) is a late prehistoric shell midden site located on the central Oregon coast. Information derived from the faunal remains, radiocarbon dates, and location and size of the midden deposits suggest the site represents a late littoral stage of cultural adaptation. Analyses of lithic artifacts, and bone and...
The purpose of this research was to examine factors associated
with the social climate of single-sex and coeducational residence
halls, fraternities, sororities, and cooperatives on the Oregon State
University campus.
The primary sources of data for this study were student
responses to the ten subscales of the URES Form R,...
The purposes of the study were: (1) to provide a descriptive
analysis and historical record of the undergraduate OSU Fourth Cycle
Urban/Rural-Migrant Teacher Corps program; (2) to follow up former
OSU Fourth Cycle corps members to determine their employment status
and attitudes toward their educational experiences; and (3) to determine...
Purpose of the Study: The purpose of this investigation was to measure some of the effects of an elementary science program, the Science Curriculum Improvement Study (SCIS) on science achievement of certain sixth grade students. Important to the problem was how the SCIS students compared with students exposed to a...
We developed and investigated machine learning methods that require
minimal preprocessing of the input data, use few training examples, run fast, and
still obtain high levels of accuracy.
Most approaches to designing machine learning programs are based on the
supervised learning paradigm – training examples are chosen randomly and given...
The two-fold purpose of this study is (1) to determine
differences in perception of counseling and guidance needs
between community college bound high school seniors,
community college counselors, and chief student services
administrators, and (2) to establish the nature and priority

Rooted in the writer's general concern with the teaching and
evaluation of writing, this study attempts to determine whether
verbally creative teachers are better able to identify verbally creative
students than are less verbally creative teachers. A second aim was
to determine whether the verbal creativity of the teacher is...
Island systems and species are susceptible to extinction because of their small population size and an ecological naiveté from an evolutionary past lacking strong competition and predation. For example, only one-fifth of the world’s bird species occur on islands, yet more than 90% of the avian extinctions witnessed during historic...
A programming paradigm can be defined as a model or an approach employed in solving a problem. The results of the research described in this document demonstrate that it is possible to unite several different programming paradigms into a single linguistic framework. The imperative, procedural, applicative, lambda-free, relational, logic and...
Soil acidity, expressed by low soil pH, causes reduced crop growth and significant economic loss. It is the most commonly overlooked and poorly understood yield-limiting factor in western Oregon and a developing concern in eastern Oregon. This publication describes the concept of soil acidity and the limitations it causes for...
