Participation in school garden programs improves health outcomes in K-12
student and is an effective tool for experiential learning. Although most schools in the Corvallis School District have a school garden, none are currently integrated into the curriculum. Using a cross-sectional,online survey, I learned that the majority of parents of...
Determining age in crustaceans is inherently imprecise because they molt
periodically and do not retain hard structures throughout their lifespan. Morphological
measurements, such as carapace length, are often used to estimate age because
methods for direct ageing do not exist. However, variability in individual growth rate
and molt frequency can...
HIV testing among high risk adolescents in Dar es Salaam, Tanzania is challenging due to poor access to test sites and AIDS-related social stigma. We adapted the OraQuick HIV Test, a self-implemented test (SIT), for low literacy youth with no internet access. To compensate for poor literacy, a picture instruction...
Today, billions of people are limited to using biomass-fueled traditional fires as a primary energy source for cooking and purification of drinking water. Reliance on open burning of biomass leads to exposure to high levels of household air pollution which has been estimated to claim over 1.5 million lives annually,...
This literature review aims to discuss the safety and use of cannabidiol (CBD) products for dogs and cats. The most prominent issue with CBD products for pets is the limited amount of resources and information available to the veterinary community.

Native prairies of the Willamette Valley are considered among the rarest of Oregon's ecosystems (Clark and Wilson, 2001). As a result of agriculture conversion, urban development and cessation of native burning, Willamette Valley prairies have become highly fragmented and invaded by non-native species, leaving little room for native plant diversity....
Models of ecosystem carbon (C) balance generally assume a strong relationship between net primary productivity (NPP), litter inputs, and soil C accumulation, but there is little direct evidence for such a coupled relationship. Using a unique 50-year detrital manipulation experiment in a in a mixed deciduous forest and restored prairie...
Olive production potential in Oregon was researched in a multi-disciplinary approach, including a grower survey, a propagation greenhouse study, and a field study, from 2018 through 2020. The Oregon Olive Grower Survey was designed to collect information relating to orchard establishment and management practices, knowledge and understanding of these practices,...
N-ary relationships, which relate N entities where N is not necessarily two, are omnipresent in real life. In this thesis, we develop a visualization technique for N-ary relationships.
First, we propose a visual metaphor that utilizes vertices and polygons to represent entities and N-ary relationships. Based on this visual metaphor,...
This study used a multi-method approach to explore factors associated with high and low depression in a sample of rural mothers living in poverty. From a sample of 117 women with very high or very low CES-D depression scores, 40 cases were randomly selected for in-depth qualitative analysis. Qualitative comments...
