The publication of Charles Darwin’s On the Origin of Species, truly a synthesized work of natural history, coincided with the emergence of specialized disciplines in the 19th century. This thesis aims to explore the relationship between the specialization of knowledge, in the form of disciplinization, and the reception of new...
U.S. foreign policy during the period between World War II and the Vietnam War has been described as part of a “nation-‐building” or “liberal” grand strategy. This thesis contends that understanding U.S. efforts to influence the internal affairs of sovereign states through the spread of liberal values and institutions during...
Fungi play critical roles in ecosystem processes and interact with plant communities in mutualistic, pathogenic, and commensal ways. Fungal communities are thought to be influenced by both associated tree communities and soil properties. However, the relative importance of the biotic and abiotic drivers of soil fungal community structure and diversity...

The principal objective of the study was first to
present a historical discussion of foreign and domestic
trade in canned salmon in the United States and Canada, and
secondly, to estimate the ex-vessel derived demand characteristics
for red and pink salmon facing the fishermen in both
countries. Secondary sources were...
The purpose of this study is to illuminate the role,
the function, and the ironic outcome of the Victory in
Vietnam Committee's campaign pamphlet to recall Senator
Frank Church of Idaho in 1967. The VVC's political
strategy was to build credibility with the media through
the recall pamphlet. The analysis...
The emission of sulfur oxides from anthropogenic sources represents a potential threat to terrestrial ecosystems. Sulfate, the most highly oxidized form of sulfur, is the most common form of inorganic sulfur in most soil environments. The sorption of sulfate may influence the alkalinity of the soil solution and as a...
Organization theory had seldom been applied to higher education
organizations but recent developments in organization theory appeared
to have potential for such application. No coherent theory of
educational change had been developed. However, one multidisciplinary
synthesis of literature on organizational change was congruent with
modern organization theory and contained both...
This essay is an exploration of identity formation and expression. Humanity's identity formations create the orientations and languages with which we use to create our knowledge and understanding of the surrounding external environment (both social and physical) and our internal environment (psychological). This essay traces the sources of identity formation...
The Purpose of the Study:
The purpose of this study was to examine early teacher
attrition through a follow-up of Washington County teachers
in Oregon who left the profession with five years of experience
or less. Focus was given to background data and
areas of greatest professional concerns for former...
The purpose of the study was to develop a schematic model
that would make motivation and learning theories more comprehensible
to beginning theory students by providing a common method of displaying
and integrating theories in such a way that they could claim
a mutual language and could be examined and...
The central purpose of this study was to examine the
influence of achievement orientation and teaching methodology on
the learning of theoretical content related to nursing.
The sample came from Senior nursing students from the
Oregon Health Sciences University, enrolled in Nursing 460 during
the academic year 1982-1983. Fall Term...
Four assumptions--
1. That there is an effective and potential demand for processed
fruit products in the Western State of Nigeria.
2. That current supply of raw materials in the Western State
of Nigeria is more than sufficient to meet the increased demand
which the short-term addition or expansion (or...
Changes in the structure of the U.S. agricultural
industry since World War II have transformed it into a
highly productive component of the domestic economy. But
these changes have not occurred without indirect costs. For
example, the reliance on agricultural chemicals has produced
environmental effects causing growing concern. In addition,...
An enhancement of the therapeutic effect and/or a reduction in
the toxicity have been shown by a variety of antineoplastic compounds
when glucose is added to the treatment schedule. A possible explanation
for this involves a selective change in intracellular pH of the
tumor tissue initiating a greater uptake of...
Shewanella oneidensis MR-1 is a gram-negative, facultative anaerobic bacteria with the capability of dissimilatory metal reduction. The ability of the organism to reduce a wide range of solid metal-oxides during anaerobic respiration makes it an ideal candidate for the powering of microbial fuel cells (MFCs), which capture the electrons discharged...
In this research, a model system for studying the effects of the toxic metabolite, methylglyoxal, was created using Chinese Hamster Ovary (CHO) cells which produce tissue plasminogen activator (t-PA). The human gene for glyoxalase I was subcloned into an inducible mammalian expression vector. This vector was then used to create...
The purpose of the work is to enable students of botany to identify
accurately Oregon ferns, both as living plants and as dried specimens.
Therefore, it provides vegetative keys to the families, genera
and species of the ferns (Class FILICINAE) found in Oregon. Correct

The gonadal steroids, testosterone and estradiol, are known to be important
modulators of neuronal functions and behaviors in most vertebrate species. These
steroid hormones also elicit changes in neuropeptide synthesis and secretion, alter
specific neurohormone receptor levels, and alter neuronal morphology and
electrophysiology. Many of the actions of androgens and...
An investigation of the correlation between a number of behavioral,
morphological and physiological parameters and dominance status of male
Ring-necked Pheasants (Phasianus colchicus) was undertaken. Dominant
males performed significantly more aggressive behaviors than
subordinates and a higher proportion of these behaviors was directed
toward distantly ranked subordinates. Animals could also...
Tissue differentiation of the primary root and its associated
laterals is reported. Secretory elements are the first of the primary
tissues to mature. They appear to be located between the precursory
phloem and pericycle in the primary root, but are more closely
associated with the pericycle in long lateral roots....
An ancient pheromonal signal is found in aquatic courting salamandrids and terrestrial courting plethodontids, two highly divergent salamander families. In the aquatic courting salamandrids Cynops pyrrhogaster and C. ensicauda, the decapeptide sodefrin is cleaved from a larger 189 amino acid Sodefrin Precursor Factor (SPF) protein and released from a gland...
Grass seed producers in Oregon's Willamette Valley have
employed the cultural practice of post-harvest open field burning
