Social scientists have studied people's responses to disasters for many decades, and behavioral commonalities and variations are summarized in different mental schemes/models in disaster studies. Integrating those findings from social science into evacuation simulation can improve simulation accuracy and eventually better support decision-making and disaster preparedness. However, this kind of...
Surface water and groundwater interactions are a key component in the functioning of stream ecosystems. Exchange of water between the stream and the hyporheic zone creates habitat for aquatic organisms and serves as a control for stream biogeochemical, thermal, and flow processes. This study takes a multi-method field-based approach to...
Developed coastlines provide a variety of recreation opportunities to coastal residents and visitors but are also the first line of defense for oceanfront development against chronic hazards like erosion and sea level rise. In the Pacific Northwest of the United States, oceanfront homes also face an additional severe but very...
This research addresses how instructors move from surface levels of diversity
understanding to deep levels. The focus was higher education instructors who taught in a
general education program, primarily teaching freshman students. The case location is at
a public institution on the West coast. Using the literature on diversity and...
Heat-related fruit damage is a common problem in the northern highbush blueberry (Vaccinium corymbosum L). This is particularly true in regions such as the northwestern United States, where summers are warm and dry, and daytime temperature regularly exceeds 32 oC. Millions of dollars of fruit damage are reported in blueberries...
Exposure to ultraviolet (UV) radiation is a primary cause of melanoma and non-melanoma skin cancer and thus represents a critical public health concern. Skin cancer risk behavior research lacks an instrument designed to assess health beliefs about UV exposure that may increase skin cancer risk by increasing risky UV exposure...
The feeding ecology of a common temperate mesoherbivore, the oligophagous sea slug Placida dendritica (Gastropoda: Opisthobranchia: Ascoglossa), was examined from April 1985 to June 1989. Along the central coast of Oregon, Placida consumed three host species: the low intertidal green algae Codium setchellii, C. fragile, and Bryopsis corticulans. Individual slugs...
Improving the methods used for the detection and estimation of fissile material mass content is essential to nuclear security and safeguards to ensure special nuclear material (SNM) accountability, control, safety and security. With the continued expansion of the nuclear industry and the need for safe management of spent fuel, improving...
Meiotic chromosome counts from 200 populations of Claytonia
(Montia) perfoliata (sensu lato) reveal a polyploid pillar complex based
on three morphologically different, chemically distinct, and geographically
defined diploids. The basic chromosome number is x=6.
Diploid C. perfoliata Willdenow with linear juvenile leaves and deltoid
mature basal leaves ranges southeastward from...
Small Unmanned Aircraft Systems (sUASs) equipped with optical sensors are capableof remotely sensing landscapes and wildlife at spatial and temporal resolutions that werepreviously inaccessible due to technical and budgetary limitations. Conventional remotesensing and photogrammetric workflows can be applied to the resulting high resolution imageryto facilitate new types of scientific inquiry....
