Members of the family Sciomyzidae, known as snail-killing or marsh flies, are unique amongst insects in that the vast majority of reared species feed exclusively on mollusks and as a result their biological control potential has been well documented in the scientific literature. However, in North America there is a...
The physical controls of snowmelt in the Pacific Northwest (PNW) are poorly
understood. While there have been numerous field and modeling investigations at the
plot and watershed scale, few studies have identified how the snow energy balance
(EB) components vary in importance both spatially and temporally. The identification
of how...
The purpose of this study is to critically analyze whether India’s National Population Policy of 2000 represents a paradigm shift in terms of how the nation-state conceptualizes and address population growth through formal population policy. Analyzed through transnational feminist theory, this study employed political discourse analysis as the research method....
Knowledge of regional-scale patterns of plant community structure and controlling factors is largely qualitative and based on numerous local studies. Data from a subsample of 10,000 field plots were used to quantify and map compositional gradients of woody plant communities across Oregon forests. Canonical correspondence analyses explained 9-14% of the...
This thesis examines one aspect of social change in Nepal. Contact
with the outside world since 1951 has provided a non-traditional
means of achieving access to highly valued occupations, resulting in
the formation of an emerging elite. High caste status is no longer
absolutely necessary to gain access to education,...
I offer a personal and prehistoric exploration of the concept of immanence, the principle of a divine force living, remaining, and operating within living creatures, inherent in the human, including the female; a unifying force that connects humans to each other, to nature, and to the earth. I examine the...
The purpose of this study was to determine that a behavioral lifestyle modification approach to weight loss changes participants' dietary intake and physical activity levels and that these changes were associated with weight loss and weight loss maintenance. Behavioral factors important in other weight control studies were also investigated to...
In undisturbed N-limited forested catchments, DON may represent over 90% of the total N lost in streams. Some ecologists have suggested that plant-derived reactive polyphenols may be responsible for DON binding and transport because polyphenol-protein complexes are known to precipitate out of solution, bind to mineral surfaces or organic matter...

Thirteen fabrics containing "Rovana" (saran), "Verel" (mod-acrylic), and rayon were examined for colorfastness to light and laundering,
shrinkage, tensile strength, elongation, abrasion-resistance
and flammability. The fabrics represented three weaves: plain,
twill and leno; and three colors: white, eggshell and turquoise. The
fiber contents, according to the manufacturers, varied from 20...
The purpose of this study was to assess reactions to and
opinions about color and color performance by women ages 45 to 54
years. Hypotheses were developed to test relationships and differences
between both perception and acceptance of color change and:
1) the three primary colors, 2) the two methods...
This thesis is a study of the clothing behavior of disadvantaged
adolescents in a rural community as it relates to the factors of social class, security level, peer acceptance and self-selection of clothing.
This study was selected because very little research in clothing
behavior has been done in disadvantaged rural...
The presence of diacetyl in sufficient concentrations to cause
off-flavor in beer is a serious economic problem affecting the brewing
industry. Research was carried out in an attempt to provide an
industrially acceptable method for reducing diacetyl to safe levels
in beer, with additional applications to frozen concentrated orange
juice,...
Mysids were sampled seasonally from the intertidal
zone of the beach to a depth of 61 m offshore along the
mid-Oregon coast. The seven mysid species collected
occurred in characteristic bathymetric zones, with members
of different genera occupying overlapping zones
while members of the same genus occupied largely different
zones....
Calcium concentration and its regulation was examined in
tissues of larval Rana catesbiana. Considerable variability was
found in tissue calcium that could not be explained by stage of development.
A seasonal effect was observed, with plasma calcium decreasing
and muscle calcium increasing during winter. Total plasma
calcium concentration reflects, within...

with clothing was measured by comparing the actual...
The basaltic landscapes of the Oregon High Cascades form a natural laboratory for examining how geologic setting and history influence groundwater flowpaths, streamflow sensitivity to climate, and landscape evolution. In the High Cascades, highly permeable young basaltic lavas form extensive aquifers. These aquifers are the dominant sources of summer streamflow...
Background: Although both transgender adults and adults living with disabilities struggle to access healthcare, both populations are underserved and understudied. Existing research either examines transgender adults and adults with disabilities as separate groups or frames disability as a health outcome a transgender person may experience. Health care utilization and health...
Hydrologic processes within mineral flat wetlands, along with their
connections to groundwater and downstream surface water in lowland agricultural
catchments are poorly understood, particularly under different land uses. In the three
field studies included in this thesis, we examined infiltration, wetland hydroperiod,
groundwater recharge dynamics, surface runoff generation, and water...
Oregon's estuaries are important ecosystems for scientific study. Consequently, knowledge of what research has been conducted helps us identify benchmarks and plan new projects. A comprehensive bibliography of published research, technical reports, local documents, and data sets is one means of recording this knowledge. For these reasons, the Guin Library...
Recent developments in Distributed Temperature Sensing (DTS) have allowed new insight into the surface-to-ground water interaction. The continuous temperature measurement by the DTS allows for cool water inflows to be located during warm summer months. These cool water inflows can then be differentiated between ground water and hyporheic exchange. The...
One goal of the Oregon Library Association's Vision 2010 is to promote a strong and diverse workforce throughout all of the state's libraries.
