This study describes Extension field staff orientations toward
poverty. Expressions on origins, solutions and definitions of poverty
were elicited from informants. Responses were then classified by
categories, coded and analyzed using the Statistical Interactive Programming
System (SIPS). Orientations were then measured by identifying
modal categories. A category was identified as...
Today's office worker is being expected to operate computers in order to
increase office productivity. While learning the new technology is a positive
challenge for most people, some students experience a negative computer
attitude when faced with computer training. This study sought to determine if
there were significant differences about...
This study examines the long-term role of interference on stand development of Douglas-fir (Pseudotsuga menziesii [Mirb.] Franco) and red alder (Alnus rubra Bong.) planted mixtures in the Central Cascades of Oregon, USA. The two species are common associates in naturally regenerated and planted conifer stands in the Pacific Northwest. Due...
The small S₁ ocean tide is caused primarily by diurnal atmospheric pressure loading. Its excitation is therefore unlike any other diurnal tide; in particular, pressure loading is maximum near the equator where the diurnal gravitational potential is zero. The global character of the S₁ tide is here determined by numerical...
The procedures outlined in this publication show you how to estimate standing volume and annual growth of timber stands—areas that are uniform in age, stand characteristics, and species. Estimates of volume and growth are helpful in planning when to harvest or how much to remove in a thinning operation. These...

When a star dies in a supernova, its constituent particles are torn apart and a gaseous cloud of atoms remains. These atoms may eventually condense again into large bodies such as planets and stars. There are three main theories as to how this happens: classical, kinetic, and non-local thermodynamic equilibrium...
This paper concerns a question that frequently occurs in various applications: Is any dispersal coupling of stable discrete linear systems, also stable? Although it has been known this is not the case, we shall identify a reasonably diverse class of systems for which it is true. We shall employ the...
The purpose of this study was to compare and describe
test score differences on the Woodcock Psycho-Educational
Battery in Spanish (BATERIA) and the Wechsler Intelligence
Scale for Children--Revised Mexican version (WISC-RM).
Analyses were performed on the two test batteries, investigating
mean score differences on the different clusters as
a function...

This thesis examines a range of generic influences in William Shakespeare's Richard II. By exploring the play's references to conflicting interpretations of history from different generic perspectives, I hope to advance a more nuanced reading of the play's dynamic staging of history. In Chapter One, I suggest that Richard II...
The biotransformation of hop aroma via yeast is a prominent topic in the brewing industry with considerable interest placed on how yeast can enhance volatile thiol production during wort fermentation. Three potent thiols are known contributors to tropical qualities in wine and beer aroma, specifically 3-mercaptohexan-1-ol (3MH), 3-mercaptohexyl acetate (3MHA),...
This thesis traces the relationship between the First World War, constructions of masculinity, and the life and poetry of T.S. Eliot. Central to this relationship is a study of homoeroticism, which the author characterizes as different from homosexuality but not exclusive of it, in late 19th and early 20th century...
Hypermediation, as described by Jay Bolter and Richard Grusin in their book Remediation, is a style of writing, recording, presenting, etc. that “makes us aware of the medium or media and (in sometimes subtle and sometimes obvious ways) reminds us of our desire for immediacy” (34). This mode of production...
During his lifetime C. S. Lewis chose to speak to Christians in plain and simple language that they could understand. Lewis taught and defended truths that he felt were discernible through reason. Morality, free will, and the divinity of Jesus Christ were fundamental to his core beliefs and teachings. His...
The phenomenon of phantom limb pain has been well documented for centuries, but little clinical work has been done to alleviate it. Physician and neuroscientist Vilayanur S. Ramachandran began researching this condition nearly two decades ago, and has discovered a promising alternative treatment: mirror-box therapy. This therapy is not yet...
This thesis discusses the African American authors Richard Wright and James Baldwin, and their views regarding how literature should be written. These views are examined as laid out in a selection of each author‟s essays, as well as through an analysis of the characters Bigger Thomas and Rufus Scott in...
The inhibition of S-aden.osylmethionine: Δ²⁴-sterol methyltransferase
(EC 2.1.1.41) activity by endogenous cellular components has
been studied in vitro. The principal inhibitors were Na⁺ and K⁺; Cs⁺,
NH₄⁺ and Li⁺ were also shown to inhibit the reaction. The inhibition
by potassium cation has been studied, and we have found that energy...
Within The Lamplighter, a novel written in 1854, Maria
Susanna Cummins defines a version of the sentimental novel
that significantly differs from the prescriptive analysis
male critics have offered for the genre. This thesis
argues that feminist theory and recent rhetorical theory
have caused a critical paradigm shift that has...
Driven by the need for high energy-density power sources, demand has
stimulated the development of small-scale engines. A small-scale engine
with a fuel supply could replace batteries and utilize higher energy-density
liquid hydrocarbon fuels; such an advance could deliver a new age of
portable devices. Currently, operable small-scale engines exist;...
Background: The identification of the loci and specific alleles underlying variation in quantitative traits is an important goal for evolutionary biologists and breeders. Despite major advancements in genomics technology, moving from QTL to causal alleles remains a major challenge in genetics research. Near-isogenic lines are the ideal raw material for...
The purpose of this watershed assessment is to provide an inventory and characterization of
watershed conditions in the Wilson River watershed and to provide recommendations that
address the issues of water quality, fisheries and fish habitat, and watershed hydrology.
Recommendations are provided in this watershed analysis to identify actions and management decisions on the part of BLM that might improve watershed health in the Trask River watershed.
How and where the ocean tides dissipate
their energy are longstanding questions with both
oceanographic and astronomical implications. Two
decades ago, Doake suggested that flexing of Antarctic
ice shelves by the underlying ocean tide is an important
energy sink, perhaps accounting for over half the global
dissipation rate. Observational constraints...
Rising energy demands and the continual push to find more energy efficient technologies have been the impetus for the investigation of waste heat recovery techniques. Diesel engine exhaust heat utilization has the potential to significantly reduce the consumption of fossil fuels and reduce the release of greenhouse gases, because diesel...
Investigations were made in the field, greenhouse, growth
chamber, and laboratory to: (a) observe the general activity of N-
(phosphonomethyl)glycine (glyphosate); (b) determine the extent of its
interaction with certain s-triazine herbicides; and (c) find an explanation
for such an interaction.
Greenhouse and growth chamber studies substantiated other
observations that...
Northern anchovy (Engraulis mordax) are a dominant forage fish in the California Current large marine ecosystem (CCLME). However, little is known about northern anchovy abundance, distribution, age structure, or population fluctuations relative to ocean conditions in the eastern boundary upwelling system off the U.S. West Coast. This thesis includes three...
The increased US domestic production of surimi from the US Pacific Coast after 1977 is a major consequence of the US's extended fisheries jurisdiction to 200 nautical miles. It is only one consequence, however, whose nature can best be understood by examining the surimi market in the context of what...
The principal objective of the study was first to
present a historical discussion of foreign and domestic
