In ethnographic research, an anthropologist becomes integrated in the community of their study. Throughout this process, the anthropologist adapts to the cultural practices and the language of this community, becoming intimately connected to them. Ethnography communicates, through the anthropologist’s experience, crucial practices, tensions, and values discovered during research. However, it...
Semen characteristics and egg production of male and female
commercial broiler breeders maintained in cages or on litter floors
were evaluated over a 24-week period. Semen was collected from males
caged singly or in pairs on a schedule of 3, 5, and 10 times (3X, 5X,
and 10X) weekly from...
Any woman's wardrobe is important, as it is to a
great extent an indication of her character. A High
School teacher, holding the position she does, as a director
of the aims and ideals of young girls must be especially
careful in her dress. Her clothing should be
neat, well...
The Beat Generation was an American counter-culture movement in the 1950's. Comprised of nomadic writers, poets, actors, musicians, and artists, the Beat movement represented no systematic philosophy and its most distinguishing characteristic was its apolitical disengagement from society. The Beats offered no substantive alternatives to the existing social order, but...
The Mark 0. Hatfield Marine Science Center (HMSC)
public education opportunities include interpretive programs
offered along the Estuary Nature Trail. The purpose of this
study was to determine the effectiveness of three informal
education programs, interpretive signs, a self-guided trail
brochure, and guided naturalist walks, in imparting
information on the...
Although employee theft is claimed by many authors to be a
significant problem in America with corrosive and damaging effects upon
business and society, very little research has been done to establish
the causes of such behavior. The purpose of this thesis was to identify,
discuss, and critically evaluate theories...
The objectives were to investigate the ability of a two-factor
central composite rotatable design (CCRD), using cooking temperature
(CT) and endpoint temperature (ET) as independent variables, to
predict selected chemical, physical and sensory meat quality
characteristics considered important by the industry, researcher and
consumer alike. Response surface analysis (RSA) was...
Thesis summarizes interviews with growers residing within the Groundwater Management Area (GWMA) in the Southern Willamette Valley of Oregon. Informal and semi-structured interviews were used to identify perceived impediments and incentives perceived by local farmers in following best management practices related to water quality. Results from the interviews were coded...
In Act I of Anton Chekhov’s play, Ivanov, Borkin strolls onto the stage drunk, with a shotgun flung over one shoulder and intent to sneak up on his contemplative cousin and employer, Ivanov. Already there is tension between light and dark, between Borkin’s playfulness --he enters on tiptoe--and Ivanov’s sobriety....
Industrial waste heat composed of saturated liquid water can be redirected to charge a thermochemical energy storage (TCES) system. This energy can be stored long-term in the inherently energy-dense chemical bonds and used for space heating. Initial reactor scale cycling experiments were conducted in tandem with TCES material improvements. Hydration...
I view the Columbia River Pastoral Letter as a guide to
God’s economy on the Columbia River. What is it that the
marine stories of the Bible tell us about what God views
as a healthy economy on the water? It is clear that the
fishermen’s encounters and stories of...
These three papers address uncertainty in the management and valuation of renewable natural resources. The first paper develops a model to integrate both stock and price uncertainty to obtain optimal resource levels. The model is an extension of Reed (1974) and shows by proof and by example that when prices...
Preliminary toxicity studies of BCNU in rats revealed that significant
prolongations of pentobarbital hypnosis were associated with
all doses employed. Investigations were undertaken to determine the
underlying mechanism responsible for this observed effect. Studies
on the in vitro metabolism of pentobarbital by hepatic microsomes
of BCNU-treated animals demonstrated that significant...
The effect of the proline analogue, L-azetidine-2-carboxylic
acid, on proline biosynthesis in Escherichia coli has been studied.
The analogue inhibits the formation of proline precursor by acting
as a false feedback inhibitor, Analysis of kinetic constants in
whole-cell preparations indicate that the inhibition is noncompetitive.
Comparative inhibitor constants for proline...
"The literature that has been produced in the
South springs from the depth and fullness of the southern nature; it is all picturesque, in one manner or an
other. Creative art is everywhere evident, especially
in the works of Edgar Allan Poe. The works of George
Washington Cable receive vitality...
Annosus root disease (Heterobasidion annosum (Fr.) Bref.) is causing notable conifer
mortality in grand fir habitat types in central Idaho. The most significant mortality is occurring in Douglas-fir (Pseudotsuga menziesii (Mirb.) Franco.) trees of all age classes. This project was designed to study some aspects of the general biology of...
Shallow coastal waters serve an important role as long-term carbon (C) sinks because they capture terrestrial C
and retain internally produced C in wetlands and sediments. We show that tropical cyclones (TCs) can lead to
rapid CO₂ efflux from estuaries, driven by physical and biogeochemical perturbation of these coastal C...
To determine if a storm event (i.e., high winds, large volumes of precipitation) could
alter concentrations of Vibrio vulnificus and V. parahaemolyticus in aquacultured oysters
(Crassostrea virginica) and associated surface water and sediment, this study followed a
sampling timeline before and after Hurricane Irene impacted the Chesapeake Bay estuary in...
The central purposes of this study were to review the
historical sources of David Kolb's formulation of experiential
learning theory, and to determine the effect and
application of Kolb's theory and Learning Style Inventory
as reflected in the literature between 1971 and 1990.
It was found that Kolb based his...
The plan of the present study was as follows:
1. A survey was made of professional textbooks dealing with methods of teaching science and biology. Only books published since 1920 were used.
2. Recently published high school textbooks, workbooks and laboratory manuals, and teachers' guides were reviewed for teaching aids....
En mayo de este año, la Revista Panamericana de Salud Pública dedicó un número especial a promover el proceso más reciente de reforma de salud en Ecuador como un caso exitoso en la región. En el artículo editorial, la directora de la Organización Panamericana de la Salud (OPS), Carissa Etienne,...
A huge discrepancy between theory and practice exists in one popular application area of functional programming--spreadsheets. Although spreadsheets are the most frequently used (functional) programs, few formal models of computation and type systems exist that would provide the foundation for creating reliable spreadsheets. Consequently, existing spreadsheets contain many errors, some...
On the Oregon coast, however, the issue of water supply has become paramount, especially given the need to restore instream flows in order to restore coastal salmon runs and meet water quality standards. With the ebb and flow of population and the economic growth of Oregon coastal communities, three hypotheses...
Transcriptome analysis of Pseudomonas fluorescensSBW25 showed that 702 genes were differentially regulated in a gacS::Tn5 mutant, with 300 and 402 genes up- and downregulated respectively. Similar to the Gac regulon of other Pseudomonas species, genes involved in motility, biofilm formation, siderophore biosynthesis and oxidative stress were differentially regulated in the...
Intact core tetraether membrane lipids of marine planktonic Crenarchaeota were quantified in water column-suspended particulate matter obtained from four depth intervals (~70, 500, 1,000 and 1,500 m) at seven stations in the northwestern Arabian Sea to investigate the distribution of the organisms at various depths. Maximum concentrations generally occurred at...
To determine whether there were differences between foreign (Arab) and American student attitudes toward academic dishonesty in Oregon State University, a seventy-eight item questionnaire designed by Kirk, (1970) was adapted and administered to two hundred and eighty Arab and American graduate and undergraduate students. Three aspects of academic dishonesty were...
Author Nella Larsen and photographer James VanDerZee are two of the most canonical figures of Harlem Renaissance studies, whose respective novels and portraits have been explored extensively, if separately, by scholars. Both Larsen's 1929 novel Passing and VanDerZee's studio portraiture of the 1920s and 1930s have been read in terms...
In Nella Larsen’s novel Passing, the character of Irene notes how “no one is every completely happy, or free, or safe,” which highlights how social limitations in American society restrict access to freedom and safety from those who do not conform to standards as defined by American society– something especially...
