The Mt. Scott watershed in northern Clackamas County, Oregon is an urban watershed that lies inside the Portland metropolitan urban growth boundary. Urbanization of the watershed began in the early 1970s and has recently accelerated. A landscape level analysis of the urbanization process was combined with the results of a...
The State of Oregon possesses a tumultuous relationship with the Earned Income Tax Credit (EITC) and currently experiences one of the lowest participation rates in the country despite attempting several policy reforms. The State of Washington has exhibited a comparatively similar relationship. However, it has adopted a distinctive policy supplementation...
Biohazardous waste refers to wastes that are potentially infectious to humans, as well as wastes from animal or plant research that could be potentially infectious to these organisms, or could alter their genetic selection process. Research resulting in generation of biohazardous waste is typically conducted at large, research-based universities. The...
This study was designed to determine whether individual
students at the eleventh grade level who were graded on a pass-fail
basis in United States History would show any difference in academic
achievement from those of a similar group marked by the traditional
ABCD-F letter-grade method. In addition, the study was...
Working conditions in the international garment industry have long been a concern and a process to assess and certify fair trade practices was developed as a means by which to improve those conditions. Standards for fair trade apparel include safe working conditions, fair wages, compliance with laws, and reduced environmental...
Understanding the mechanism of resistance, relative fitness and competitiveness of herbicide resistant biotypes is important to predict population dynamics and to establish resistance management strategies. This study was conducted to determine the level of resistance to acetolactate synthase (ALS) inhibitors and the mechanism of resistance of ALS-inhibitor resistant downy brome...
This study explores how multispecies social networks influence small farmers' perceptions of and responses to climate change across Oregon. Local food sovereignty and food system resilience depend on a robust local food system in which small farms play a critical role. To maintain their viability, small farmers must adapt to...
Damage estimates to the built environment from tsunamis are important for disaster mitigation, including planning emergency response and recovery. This dissertation evaluates the damage states of buildings in a small urban coastal city, Seaside, Oregon, from tsunami hazards generated by a Cascadia Subduction Zone (CSZ) event. This study is separated...
Tocopherols are plant secondary metabolites that are known collectively as
vitamin E. Tocopherol compounds act as potent antioxidants by quenching free
radicals and protecting fatty acids from oxidative damage. In humans (in vivo)
tocopherols protect membrane lipids from breaking down, while in oils (in vitro)
tocopherols protect fatty acids from...
