Zora Neale Hurston was a Black American writer
during the period of the Harlem Renaissance. The
purpose of this study is to show that three of her four
novels form a protracted discussion of a particular
type of freedom which was of especial interest to
Hurston. The study seeks to...
Yellow toadflax (Linaria vulgaris) and Dalmatian toadflax (Linaria
dalmatica) are members of the figwort (Scrophulariaceae) family.
They were introduced into North America as ornamental plants because of their showy, snapdragon-like flowers. Yellow toadflax was brought from Wales in the mid-1800s as a garden flower by Ranstead, a Welsh Quaker who...
Yellow starthistle (Centaurea solstitialis L.) is a member of the knapweed
(Centaurea L.) complex. It is poor forage for all livestock and causes
“chewing disease,” a nervous disorder, in horses. Yellow starthistle infests
millions of acres in California and the Pacific Northwest. Infestations range
from scattered plants to dense stands...
This report describes sediment testing done on the Yaquina River benthos between river miles 6 and 11 (a section between Yaquina and Toledo). The sediments were found to be safe for in-water disposal, thus enabling dredging to proceed.
Dedicated to recording, portraying, and indicting
the social inequities that he witnessed in nineteenth
century Victorian England, one of Charles Dickens' many
concerns was the roles assigned to women both in the
public and private spheres.
The purpose of this thesis is to examine the
narratives of Amy Dorrit and...
A sample of 1,003 women, age 22 in 1983-84 and age 27 in 1988-89, were
selected from the National Longitudinal Survey of Youth. Personal, familial, and
geopolitical predictors of alcohol consumption were evaluated at each time period and
longitudinally. The study integrated macro- and micro-level influences to determine
their influence...
The issue of Navy women in combat has been widely discussed
since women first served during World War I. In this paper I intend to
present the political, philosophical, and historical reasoning behind the
changing of the regulations to allow women in combat.
History shows that the Navy has faced...

The 18 winegrape varieties in this trial were in fifth leaf in 1994. Vines were pruned in February to either a Scott Henry (4 arms on a vertical trellis using two fruiting wires 12 inches apart at 30 and 42 inch height) or a guyot (a double arm on a...
Four year old vines of 18 varieties were cane pruned, trained to a Scott Henry, thinned before veraison, and harvested in October and November 1993. Two of the varieties, Chardonnay and Cabernet Sauvignon, were used as standards. Only four varieties were spur pruned to reduce cropping or cluster size: Dolcetto,...
The natural fall of trees in riparian areas is an important source of coarse woody debris for mountain streams, improving fish habitat and influencing stream morphology. Existing models consider the probability of coarse woody debris entering a stream channel based upon trees having a random direction of fall without consideration...

Agricultural scientists recognize farmer knowledge and experience can provide important contributions to the development of new agricultural technologies. However, insufficient use has been made of this valuable resource because farmer knowledge and experience are difficult to collect, quantify, and evaluate.
The protagonists in the fiction of Paule Marshall, Alice Walker, and Toni
Morrison illuminate American cultural perceptions of black women and illustrate how the
creators of these characters hope to change those perceptions. I studied Paule Marshall's
Daughters, Alice Walker's Meridian and The Color Purple, and Toni Morrison's The
Bluest...

Seed size, abundance, viability, dormancy, and germination requirements strongly influence plant establishment and therefore are important considerations in restoration of native vegetation. These characteristics provide criteria for selection of suitable species, development of collection and pretreatment methods, and determination of seeding densities. The first set of objectives of this study...
This article is based on a total of 353 observations, many of which were systematic censuses.
At West Beaver Pond, Llewellyn made 225 observations of waterbirds during 1982-June 1993. He noted a total of 19 taxa; 53% were seen in five or more of the 10 years with many observations....

Between Siletz River Mile (RM) 50.0 and 50.6, Llewellyn made 151 observations of waterbirds during 1981-1993. He noted a total of 12 species; most were seen during several years. Hooded and Common mergansers and American...
Stephens winter wheat was grown using conventional furrow irrigation and surge irrigation on 12 one-half-acre plots. Both systems were operated simultaneously four times during the season. Conventional irrigation applied 26.5 ac-in/ac of water with runoff of 0.8 ac-in/ac and infiltration of 25.7 ac-in/ac. Surge irrigation applied 13.7 ac-in/ac with 0.5...
Water quality problems related to excessive algal
growth, high nutrient loading, and low flows have been

agricultural, and urban areas. Located in the Portland...
Population size of Clavibacter michiganensis subsp.

This study addresses the relationship between thermal microfronts and coherent vortex structures in homogeneous turbulence. The turbulence is created by mean shear in a weakly stratified flow. The data set is generated by direct numerical simulation providing highly resolved instantaneous three‐dimensional fields of fluctuating velocity and temperature (1603 data points...
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...
A concept image is that collection of all images, pictures, symbols, definitions
and properties associated with any given mathematical concept. One of the
most important components in the mental representation of concepts in the concept
image of advanced mathematical thinkers is visualization. This component, in
turn, is indispensable in the...
During the last two years thrips have been suspected of causing shoot damage in the form of reduced leaf size and stunted vine growth in one vineyard in the Cave Junction area of Southern Oregon. While there can be several problems that can cause this symptom in grapes, it was...
Video Respite (VR) refers to a series of videotapes
designed to engage cognitively impaired individuals so
that caregivers can have opportunities for respite.
Previous work has evaluated the impact of VR with family
caregivers. This study assessed use of VR in special
care units (SCUs) for persons with dementia. The...
Vernalization plays a fundamental role in the adaptation of winter cereals to their growing environment by controlling their growth habit, thereby allowing them to escape cold injury. Because of the climatic conditions of the region, dry summers and wet winters, growers sometimes cannot plant all of their winter wheat in...
Genetic differences between early and late forms of
Alaskan chinook salmon (Oncorhynchus tshawytscha) were
identified using two genetic approaches: mitochondrial
DNA (mtDNA) analysis and protein electrophoresis. The
study populations consisted of early- and late-run chinook
salmon in each of the Kenai and Kasilof rivers in Alaska,
and a single population...
Contingent valuation has been used to elicit values

to biased contingent...
